fix(test-compose): set CERTCTL_AGENT_BOOTSTRAP_TOKEN placeholder (deploy-vendor-e2e job)

deploy-vendor-e2e was hidden behind the go-build-and-test failure; once
that cleared (b1ca046), the vendor-e2e job actually booted certctl-test-
server for the first time in a while and hit the Sprint 5 ACQ RED-003
fallout:

  Failed to load configuration: phase-2 SEC-H1 fail-closed guard:
  CERTCTL_AGENT_BOOTSTRAP_TOKEN is empty and
  CERTCTL_AGENT_BOOTSTRAP_TOKEN_DENY_EMPTY=true — refuse to start.

The Sprint 5 RED-003 closure flipped DENY_EMPTY's default from false→true
in production code, but the test compose stack never set a token. The
fail-closed guard (internal/config/config.go:1054) refuses to start
unless one of:
  - CERTCTL_AGENT_BOOTSTRAP_TOKEN is non-empty, OR
  - CERTCTL_DEMO_MODE_ACK=true (demo-mode override), OR
  - CERTCTL_AGENT_BOOTSTRAP_TOKEN_DENY_EMPTY=false (warn-mode escape
    hatch for v2.1.x→v2.2.x upgrade window)

This is the e2e TEST stack with production-like auth posture
(CERTCTL_AUTH_TYPE=api-key), not a demo stack. The right fix is the
first option — set a deterministic placeholder token. Picking the
warn-mode escape hatch would silently test the wrong posture; picking
DEMO_MODE_ACK would also flip CERTCTL_AUTH_TYPE expectations.

Also fixed deploy/ENVIRONMENTS.md: the entry still said
'default flip to true scheduled for v2.2.0', which became stale on
2026-05-16 when Sprint 5 ACQ RED-003 actually flipped it. Updated the
default column from `false` to `true` and rewrote the description
to reflect the current posture + the v2.1.x→v2.2.x warn-mode escape
hatch.

Verified locally: all 53 locally-runnable ci-guards still green
(4 skipped: H-001-bare-from + H-002-bare-compose-image + digest-validity
+ no-precompiled-binary, all need docker-registry network).

CI re-run on this commit should clear deploy-vendor-e2e's
certctl-test-server dependency-failed-to-start step.

+    `<a, bc>`-vs-`<ab, c>` concatenation collision attack on the
+    bare-concat form), v1. version-prefix lock, idle expiry,

+    constant-time compare against the SHA-256-hashed copy on the

+    fail-fatal initial-key bootstrap. A regression in any one of
+    these branches is a security incident; the floor catches it
+    before the commit lands. The 15-case negative-test matrix in
+    service_test.go is the load-bearing harness; the in-memory

+    spec ships the package at 91.5%, validated by 8 mandated
+    negatives + ~12 coverage-lift tests. Every fail-closed branch
+    is load-bearing for the security surface (default-OFF posture
+    only matters if every "disabled" path returns ErrDisabled
+    BEFORE any DB lookup; constant-time defense only matters if
+    every path goes through verifyDummy on the no-credential leg).
+    A regression that drops a fail-closed branch's coverage below
+    90 is a real security risk — gate trips, operator audits.
+

+    any future field added without a validator.
+
+internal/auth/user/domain:

+  why: |
+    Bundle 2 Phase 1 — User domain (federated-human identity).
+    OIDCSubject + OIDCProviderID unique-index per the Phase 2
+    schema, WebAuthnCredentials JSONB reserved for v3, Validate()
+    enforces every on-disk invariant. The package ships at 96.4%
+    coverage. Floor at 90 to catch any future field added without
+    a validator.
+
+    Phase 13 prompt explicitly enumerates internal/auth/user/ at
+    floor 90. The parent (non-domain) directory has no Go source —
+    the user upsert lives in internal/auth/oidc/service.go alongside
+    group resolution + role mapping (cohesive sequence within the
+    OIDC callback). Splitting upsertUser into a separate
+    internal/auth/user/ service package would harm cohesion without
+    adding test value; the domain layer's invariant coverage is
+    where the floor actually applies.

+#
+# Why
+# ===
+# The Helm CronJob at deploy/helm/certctl/templates/backup-cronjob.yaml
+# and the operator runbook at docs/operator/runbooks/postgres-backup.md
+# both document a pg_dump -Fc -based backup strategy, but the dump has
+# never been restored end-to-end under CI. A backup procedure that has
+# never been restore-tested is not a backup procedure. This workflow
+# adds the missing assertion.
+#
+# What
+# ====
+# Each Monday at 07:00 UTC (1h offset from loadtest.yml's 06:00 UTC
+# slot so they don't fight for runners), boot a real Postgres
+# 16-alpine container against the same digest pin as the production
+# deploy/docker-compose.yml, exercise the audit_events hash chain
+# with a small synthetic workload, pg_dump the database, drop the
+# schema, pg_restore, and assert the chain head + row count
+# round-trip byte-for-byte.
+#
+# The chain head round-trip property is the load-bearing assertion.
+# Migration 000047 hashes each audit_events row's canonical payload
+# with `to_char(timestamp AT TIME ZONE 'UTC',
+# 'YYYY-MM-DD"T"HH24:MI:SS.US"Z"')`. Any TIMESTAMPTZ-precision loss
+# in the dump→restore path (a real concern across major Postgres
+# upgrades or with --format=plain) would corrupt the hash. The whole
+# point of testing instead of trusting docs is to PROVE the property
+# under a real workload.
+#
+# Workflow boundaries
+# ===================
+# - Does not exercise PITR / WAL archiving (DR runbook owns that).
+# - Does not exercise the Helm CronJob's S3 sink or scheduling
+#   (operator-side concern, not a property of the dump shape).

 # Changelog
 
-## v2.1.0 - Auth Bundle 1: RBAC primitive ⚠️
+## Unreleased
+
+### Breaking changes (scheduled for v2.2.0)
+
+- **SEC-H1 staged: `CERTCTL_AGENT_BOOTSTRAP_TOKEN_DENY_EMPTY` opt-in flag.**
+  Phase 2 of the architecture diligence remediation (2026-05-13) introduces
+  a new env var that, when set to `true`, makes the server refuse to start
+  unless `CERTCTL_AGENT_BOOTSTRAP_TOKEN` is also set to a real value.
+  Default in this release: `false` (preserves the v2.1.x warn-mode
+  pass-through behavior for backward compatibility). Default flip to
+  `true` is scheduled for v2.2.0 per `WORKSPACE-ROADMAP.md`.
+
+  **Operator action before the v2.2.0 upgrade:** generate a real
+  bootstrap token (`openssl rand -base64 32`) and set
+  `CERTCTL_AGENT_BOOTSTRAP_TOKEN` in your env. When v2.2.0 ships, the
+  deny-empty default flips to `true` and a missing or empty token will
+  fail closed at boot. Operators with the token already set: no action
+  required.
+
+- **SEC-M4: `CERTCTL_ACME_INSECURE` now requires explicit ACK.**
+  Pre-Phase-2, `CERTCTL_ACME_INSECURE=true` produced only a boot-time
+  WARN log. Post-Phase-2 (THIS release), the server refuses to start
+  unless `CERTCTL_ACME_INSECURE_ACK=true` is set alongside it. ACME
+  directory TLS verification is the load-bearing defense against a
+  network attacker intercepting ACME enrollment; the existing flag was
+  too easy to flip via a copy-pasted Pebble runbook.
+
+  **Operator action:** if you intentionally run against a self-signed
+  ACME server (Pebble, step-ca, internal dev), add
+  `CERTCTL_ACME_INSECURE_ACK=true` to your env. Production deploys
+  MUST never set either flag.
+
+- **SEC-H3: `CERTCTL_DEMO_MODE_ACK` is no longer sticky — 24h re-ack required.**
+  Pre-Phase-2, setting `CERTCTL_DEMO_MODE_ACK=true` was sticky for the
+  lifetime of the container. Post-Phase-2, operators must ALSO set
+  `CERTCTL_DEMO_MODE_ACK_TS=$(date +%s)` to a unix epoch within the
+  last 24h. The next container restart past 24h refuses to start
+  unless a fresh TS is supplied. Catches the "forgotten demo deployment
+  promoted to production" failure mode.
+
+  **Operator action:** demo deploys must set `CERTCTL_DEMO_MODE_ACK_TS`
+  at every `docker compose up`. The demo Compose helper script handles
+  this automatically when wired; standalone demo deploys add it
+  manually. Production deploys: this guard is irrelevant
+  (`CERTCTL_DEMO_MODE_ACK` should not be set in production).
+
+### Fixed
+
+- **GitHub #13 / Hotfix #19 — GUI "Something went wrong" after browser
+  refresh on a real (non-demo) install.** Refresh-after-login wipes the
+  in-memory `apiKey` (deliberate — the GUI never persists it to
+  localStorage as a security posture). The next API call returns a
+  bare 401 with no `WWW-Authenticate` header. Pre-Hotfix-19 the
+  AuthProvider 401 handler only hard-navigated to `/login` when `cause`
+  was a recognised OIDC session-expiry category (`idle_timeout` /
+  `absolute_timeout` / `back_channel_revoked`); bare 401s
+  (`cause === ''`) and `invalid_token` causes fell through to an
+  in-place `AuthGate` state flip that unmounted `BrowserRouter` under
+  an in-flight `<Link>`, triggering a `react-router-dom` invariant
+  that surfaced via `ErrorBoundary` as the "Something went wrong"
+  screen. **Fix:** every 401 now hard-navigates to `/login` regardless
+  of cause; the cause-aware UX is preserved by forwarding
+  `?session_expired=<cause>` only when cause is non-empty (bare 401s
+  redirect to plain `/login`). Three-line change in
+  `web/src/components/AuthProvider.tsx`; 4 regression tests added to
+  `AuthProvider.test.tsx` (empty cause from `/targets`, `invalid_token`
+  cause, `idle_timeout` cause, already-on-`/login` no-op guard).
+  Closes #13.
+
+### Security
+
+- **Alg-downgrade defense relaxed for Keycloak-shape IdPs (v2.1.0 pre-tag fix).**
+  Pre-fix, the IdP-bind alg-downgrade check at `internal/auth/oidc/service.go`
+  refused to load any OIDC provider whose discovery doc advertised HS256 /
+  HS384 / HS512 / `none` in `id_token_signing_alg_values_supported` —
+  even if RS256 was ALSO advertised. This broke binding against
+  Keycloak 26.x (and a handful of other real IdPs) which list every alg
+  the codebase is capable of in their discovery doc, regardless of which
+  one the realm actually signs with. The v2.1.0 Phase-10 live-IdP smoke
+  surfaced the regression: 6 testcontainers-Keycloak integration tests
+  failed with `oidc: IdP advertises weak signing algorithms (HS*/none); refusing to use as defense against downgrade attacks: HS256`.
+  **Fix:** the check now refuses only when the intersection of advertised
+  vs `DefaultAllowedAlgs` is EMPTY — an IdP advertising HS256 alongside
+  RS256 binds successfully, but an IdP advertising HS-only / none-only
+  still fails closed. The per-token alg pin at sig-verify time
+  (`isDisallowedAlg`, service.go ~L1177) remains the load-bearing defense
+  against the actual algorithm-confusion attack (forged HS256 token
+  signed with the IdP's RS256 pubkey as HMAC secret) — go-oidc/v3's
+  verifier rejects any token whose `alg` header isn't in the configured
+  allow-list, regardless of what the discovery doc claims. Updates:
+  `Service.getOrLoad` alg-check loop rewritten to compute intersection;
+  `ErrIdPDowngradeAdvertised` docstring reflects new semantics;
+  `TestDiscovery` dry-run validator surfaces HS*/none alongside RS* as
+  an informational note (not a hard fail); `docs/operator/auth-threat-model.md`
+  alg-allow-list section updated to call out the load-bearing-defense
+  hierarchy. Tests: `TestService_IdPDowngradeDefense_RS256PlusHS256_BindsSuccessfully`
+  (positive — Keycloak-shape) + `TestService_IdPDowngradeDefense_RejectsHSOnlyAdvertised`
+  (negative — pathological intersection-empty case) +
+  `TestService_RefreshKeys_CatchesPostLoadDowngrade` updated to assert
+  intersection-empty post-rotation; `TestTestDiscovery_AlgDowngrade_HS256AlongsideRS256_BindsWithNote`
+  + `TestTestDiscovery_AlgDowngrade_HSOnly_StillTrips_HardFail` pin the
+  dry-run validator's new behavior.
+
+### Tests
+
+- **Vitest coverage for the 2026-05-10/11 GUI batch (Audit 2026-05-11 Fix 12).**
+  The original GUI-batch commit `661b6db` claimed `npx tsc --noEmit PASS`
+  but shipped no Vitest cases for the new surfaces. The regression-
+  prevention layer was missing — a future refactor of `KeysPage`'s
+  assign modal could silently drop scope_type handling, the LOW-1 demo
+  banner could be hidden by a stray predicate flip, the LOW-11 hide of
+  the delete button on default roles could disappear and let operators
+  click straight into a backend 409, and nothing would surface in CI.
+  This closure adds 35 new test cases across five files:
+  `web/src/pages/auth/UsersPage.test.tsx` (new, 8 cases pinning the
+  active/deactivated/reactivate flow + provider filter + empty state +
+  loading state), `web/src/pages/auth/AuthSettingsPage.test.tsx`
+  (extended +4 cases pinning the MED-12 runtime-config panel —
+  alphabetical sort, `(empty)` placeholder, 403 silent-hide),
+  `web/src/pages/auth/KeysPage.test.tsx` (extended +8 cases pinning
+  the HIGH-10 GUI half — scope_type=global/profile/issuer body shape,
+  expires_at omission vs RFC3339 promotion, whitespace-only scope_id
+  rejection, demo-anon row mutation-button hide),
+  `web/src/pages/auth/RoleDetailPage.test.tsx` (new, 9 cases pinning
+  the MED-8 scope picker + the LOW-11 default-role delete-button hide
+  via the `DEFAULT_ROLE_IDS` set against `r-admin` + `r-auditor`),
+  `web/src/components/AuthProvider.test.tsx` (new, 5 cases pinning the
+  LOW-1 demo-banner visibility predicate — `authType==='none' &&
+  !loading` — across happy/api-key/oidc/loading/rejected branches; the
+  rejected-fetch path keeps the banner visible because the catch
+  treats it as an old-server-fallback to demo-mode, and that behavior
+  is pinned here so a future change surfaces in the diff). 40/40
+  test-file-scoped pass; `tsc --noEmit` clean.
+
+### Security
+
+- **CSRF rotation on logout closes HIGH-2 fourth call site (Audit 2026-05-11 Fix 13).**
+  The HIGH-2 closure (`dev/auth-bundle-2`) documented four
+  `RotateCSRFTokenForActor` call sites: login completion (fresh by
+  construction), Assign/RevokeRole on role-mutation (wired), Logout, and
+  an explicit operator endpoint. The 2026-05-11 review verified only 3
+  of the 4 — Logout did NOT rotate the actor's sibling sessions
+  post-revoke, leaving a window where a token captured pre-logout
+  (browser DevTools, malicious extension, session-storage leak) could
+  be replayed against the user's other-device/other-browser sessions
+  until those sessions hit their own idle/absolute expiry.
+  `SessionMinter` interface extended with `RotateCSRFTokenForActor`;
+  `Logout` invokes it after `Revoke(sess.ID)` succeeds. The
+  `auth.session_revoked` audit row gains a `csrf_rotated` detail key
+  carrying the rotated count so SOC / SIEM can correlate logout events
+  with CSRF churn. The no-cookie + invalid-cookie 204 short-circuit
+  paths skip rotation (no session row to rotate against). 3 regression
+  tests in `internal/api/handler/auth_session_oidc_test.go` pin the
+  happy path + the two short-circuit branches. The explicit operator
+  endpoint (4) remains intentionally unbuilt — the three automatic
+  triggers (login + role-mutation + logout) cover the threat model;
+  operators who want a nuclear option can use the existing
+  `RevokeAllForActor` flow which forces re-login → fresh session →
+  fresh CSRF. **HIGH-2 fully closed across all four documented call
+  sites.**
+
+- **Demo-mode residual-grants detector + cleanup endpoint + CI guard (Audit 2026-05-11 A-8).**
+  HIGH-12 (closure `b81588e`) added a fail-closed bind-address guard
+  that refuses startup when `CERTCTL_AUTH_TYPE=none` binds non-loopback
+  without `CERTCTL_DEMO_MODE_ACK=true`. The Phase 2 leg of that spec —
+  production-startup banner when `actor-demo-anon` has residual role
+  grants in `actor_roles` plus a CI guard banning new synthetic-admin
+  code paths — was deferred. This closure lands all three deferred
+  legs. (1) `cmd/server/preflight_demo_residual.go` runs after the DB
+  is open + audit service is constructed, before the HTTPS listener
+  starts; under any non-`none` auth type it queries `actor_roles` for
+  `actor-demo-anon` and emits a WARN log + `auth.demo_residual_grants_detected`
+  audit row when the row is present. The migration 000029 baseline
+  unconditionally seeds the `ar-demo-anon-admin` row at install time,
+  so EVERY production deploy will see this WARN on first boot — the
+  intended cutover workflow is documented at `docs/operator/security.md`.
+  (2) `POST /api/v1/auth/demo-residual/cleanup` is an admin-class
+  (`auth.role.assign`) cleanup endpoint that removes every
+  `actor-demo-anon` row from `actor_roles` and returns
+  `{"removed": <int64>}`; idempotent (a second call returns
+  `removed:0`), refuses 503 under `Auth.Type=none` (deleting the row
+  would break the demo path), audit-logs every invocation. (3) New
+  env var `CERTCTL_DEMO_MODE_RESIDUAL_STRICT` (default `false`)
+  pivots the WARN to fail-closed startup refusal for operators who
+  want a paranoid hostile-environment posture. (4) CI guard
+  `scripts/ci-guards/no-new-synthetic-admin.sh` pins the 17-entry
+  allowlist of source files that may reference the `actor-demo-anon`
+  literal; new runtime code paths that resolve to the synthetic actor
+  are rejected at PR time so the credibility gap stays closed. The
+  closure was framed as "credibility gap, not exploitable
+  vulnerability" — the residue requires a regression elsewhere in the
+  middleware chain to be exploitable. After this fix, the canonical
+  acquisition-readiness narrative ("RBAC primitive with no
+  synthetic-admin fallback") is fully true. Operator runbook at
+  `docs/operator/security.md#demo-to-production-cutover-audit-2026-05-11-a-8`.
+
+- **OIDC provider "Test connection" panel (Audit 2026-05-11 Fix 09 — MED-5 GUI half).**
+  MED-5's backend dry-run endpoint (`POST /api/v1/auth/oidc/test`, gated
+  `auth.oidc.create`) shipped on `dev/auth-bundle-2` but had no GUI caller —
+  the `authOIDCTestProvider` function in `web/src/api/client.ts` was dead
+  code. Operators had to complete the create form blind, save, then click
+  "Refresh" to discover whether the issuer URL worked; failures left a
+  broken provider row in the database that had to be deleted before
+  retrying. New shared component
+  `web/src/pages/auth/OIDCTestConnectionPanel.tsx` calls the backend
+  against the live form state and renders a four-row status panel inline:
+  Discovery fetched, JWKS reachable, supported algs (warns when the IdP
+  advertises none), and RFC 9207 iss-parameter advertisement (informational
+  `·` glyph, not ✗, because the spec is SHOULD). Backend per-leg `errors[]`
+  flow into an inline bullet list. The panel is mounted in the
+  OIDCProvidersPage create modal AND the OIDCProviderDetailPage edit form —
+  the edit-form half is load-bearing for verifying IdP rotations (Keycloak
+  realm rename, Okta tenant move) without committing first. Run button is
+  disabled until the issuer URL is non-empty (whitespace-trimmed); the
+  component is read-only — safe to run repeatedly. 8 Vitest tests pin the
+  glyph-vs-glyph contract (✓/✗/⚠/·), the button-disabled-without-issuer
+  shape, and the test-id-suffix collision-prevention when the panel is
+  mounted twice on the same page.
+
+- **OIDC JWKS health panel + Refresh-now button (Audit 2026-05-11 Fix 10 — MED-7 GUI half).**
+  MED-7's backend endpoint `GET /api/v1/auth/oidc/providers/{id}/jwks-status`
+  (commit `d85114f`) shipped the per-provider verifier counters on
+  `dev/auth-bundle-2` but the GUI never called it. The audit doc had
+  prematurely flipped the row to CLOSED; `authOIDCJWKSStatus` in the
+  API client was dead code. Operators investigating "why is login
+  failing for this IdP" couldn't see `last_refresh_at`,
+  `rejected_jws_count`, or `last_error` from the GUI — they had to
+  drop to curl. New shared component
+  `web/src/pages/auth/OIDCJWKSStatusPanel.tsx` queries the endpoint
+  via TanStack Query (30s `staleTime`, `retry: 0` so a 403 hides the
+  panel silently for callers without `auth.oidc.list`) and renders
+  six dt/dd rows: Last refresh (with `(never — cold cache)` sentinel
+  when the timestamp is empty), Refresh count, Rejected JWS count,
+  Last error (red treatment when non-empty, `(none)` sentinel
+  otherwise), RFC 9207 iss param ("supported by IdP" / "not
+  advertised"), and Current KIDs (`(not exposed — query jwks_uri
+  directly)` sentinel when the backend declines to expose the list).
+  A "Refresh now" button invokes the existing
+  `POST .../refresh` (RefreshKeys path) and invalidates the panel's
+  query so the freshly-updated counters render without a page
+  reload. The button is hidden for callers without `auth.oidc.edit`
+  via the panel's optional `canRefresh` prop. Mounted on
+  `OIDCProviderDetailPage.tsx` between the read-only field display
+  and the Actions section. 9 Vitest tests pin: loading state,
+  happy-path-all-six-rows, 403-hides-panel, refresh-invalidates-
+  query, refresh-failure-surfaces-inline-without-hiding-panel,
+  never-refreshed-cold-cache-sentinel, current-kids-empty-not-
+  exposed-sentinel, last-error-red-treatment, and canRefresh=false-
+  hides-the-button.
+
+- **UsersPage sidebar nav entry (Audit 2026-05-11 Fix 11 — MED-11
+  discoverability).** The MED-11 closure shipped `UsersPage.tsx` + wired
+  the `/auth/users` route in `web/src/main.tsx`, but the sidebar
+  navigation never gained a corresponding entry. Operators reached the
+  federated-user-admin surface (used during compliance audits — "show
+  me last login for every IdP-federated user") only by knowing the URL.
+  A page that exists but isn't navigable is a half-finished page. New
+  Users entry under the Auth section in `web/src/components/Layout.tsx`
+  sits between Sessions and Roles (federated-identity grouping). Three
+  Vitest tests in `Layout.test.tsx` pin the link's presence, the
+  `/auth/users` destination, and the DOM ordering relative to Sessions
+  so a future refactor that re-orders or removes the entry surfaces in
+  the diff.
+
+- **Scope-aware actor-role revoke (Audit 2026-05-11 A-4).**
+  HIGH-10 made it possible to grant the same role to the same actor at
+  multiple scopes (e.g. `r-operator` on `profile=p-acme` AND `profile=p-globex`)
+  via the unique constraint extension on `actor_roles`, but
+  `ActorRoleRepository.Revoke` ignored `(scope_type, scope_id)` and
+  unconditionally deleted every variant. Operators who wanted to drop
+  one scoped grant had to nuke them all and re-grant the remainder —
+  a race window where the actor's access was briefly different. The
+  `DELETE /v1/auth/keys/{id}/roles/{role_id}` endpoint now accepts
+  optional `?scope_type=` / `?scope_id=` query params that narrow the
+  revoke to a single variant; no-match returns 404. The legacy "revoke
+  every variant" semantic is preserved when the query params are
+  absent, so existing CLI / GUI buttons keep working unchanged. The
+  audit row's `details` payload records which mode fired so SOC / SIEM
+  can distinguish wide cleanups from targeted demotions. MCP tool
+  `certctl_auth_revoke_role_from_key` gains optional `scope_type` +
+  `scope_id` input fields with matching semantics. Documented in
+  `docs/operator/rbac.md` under "Revoke: legacy 'all variants' vs
+  scope-selective."
+
+### Security (BREAKING — silent-elevation closure)
+
+- **HIGH-10 actor-role scope is now enforced (Audit 2026-05-11 A-1).**
+  Pre-fix, `actor_roles.scope_type` / `scope_id` (added in migration 000043
+  by the HIGH-10 closure) were persisted by Grant + accepted on the handler
+  body + surfaced through the GUI/MCP — but the load-bearing
+  `EffectivePermissions` SQL never read them. A profile-scoped grant
+  silently elevated to global at authorization time. Canonical CRIT-5

+  correctly**: every existing `actor_roles` row with `scope_type != 'global'`
+  now takes effect.

+
+### Security (BREAKING)
+
+- **Federated-user deactivation now actually blocks login (Audit 2026-05-11 A-2).**
+  The MED-11 closure shipped `users.deactivated_at` + `DELETE /api/v1/auth/users/{id}`
+  + cascade-session-revoke, but the column was a "lying field" three legs over: the
+  postgres user repository never SELECTed it (so `User.DeactivatedAt` always read
+  nil), the `Update` SQL never wrote it (so the handler's mutation was a no-op),
+  and the OIDC `upsertUser` path never checked it (so the next login under the
+  same `(provider, subject)` tuple re-minted a session and re-elevated the user).
+  The cascade-revoke remained correct for the current cookie only. **Operator
+  advisory: if you deactivated a federated user between the MED-11 closure
+  (Bundle 2 merge `dea5053`) and the v2.1.0 release tag, verify the user cannot
+  OIDC-log-in after upgrading — the column took no effect at login time before
+  this fix. If needed, re-run the deactivation against the upgraded server.**
+  Closure: `userColumns` + `scanUser` now read `deactivated_at` via `sql.NullTime`;
+  `Create` + `Update` write it explicitly; `upsertUser` returns the new
+  `ErrUserDeactivated` sentinel before mutating fields (preserves `last_login_at`
+  forensics on rejected logins); `classifyOIDCFailure` surfaces the rejection
+  as audit category `user_deactivated`. Self-deactivate guard on
+  `DELETE /api/v1/auth/users/{id}` returns HTTP 409 + audit row
+  `auth.user_deactivate_self_rejected` (prevents an admin from one-way-door
+  locking themselves out via the standard handler — break-glass remains the
+  recovery path). New inverse endpoint `POST /api/v1/auth/users/{id}/reactivate`
+  (gated `auth.user.deactivate` — reactivation is the inverse op, not a separate
+  privilege) clears `deactivated_at`; emits audit row `auth.user_reactivated`.
+  Sessions revoked at deactivation stay revoked across reactivation — the user
+  must complete a fresh OIDC login. GUI: `UsersPage.tsx` now renders a Reactivate
+  button on deactivated rows. CWE-862 (missing authorization at the user-state
+  boundary). SOC 2 CC6.3 + ISO 27001 A.9.2.6 compliance-table-flipping fix.
+- **`__Host-` cookie prefix on all three auth cookies (Audit 2026-05-10 MED-14).**
+  The session cookie, CSRF cookie, and OIDC pre-login cookie are renamed from
+  `certctl_session` / `certctl_csrf` / `certctl_oidc_pending` to
+  `__Host-certctl_session` / `__Host-certctl_csrf` / `__Host-certctl_oidc_pending`
+  to gain browser-enforced subdomain-takeover protection (a `__Host-*` cookie can
+  only be set with `Path=/` + `Secure` + no `Domain` attribute, and the browser
+  rejects subdomain attempts to overwrite it). **Active sessions invalidate on
+  the rolling deploy that lands this change** — operators must re-authenticate
+  once after upgrading. The GUI's CSRF cookie reader was updated in lockstep.
+  See `docs/migration/oidc-enable.md` for operator-facing detail.
+
+### Security
+
+- **OIDC `allowed_email_domains` now editable in the GUI (Audit 2026-05-11 A-3).**
+  The backend gate that rejects logins whose email domain is outside the
+  configured allowlist landed in v2.1.0 (CRIT-5 closure, 2026-05-10), but the
+  GUI never exposed the field — GUI-driven operators had to use the API
+  directly to configure tenant isolation against multi-tenant IdPs (Auth0,
+  Azure AD common endpoint, Google Workspace). The OIDCProvidersPage create
+  modal and OIDCProviderDetailPage detail view now render a chip-style
+  multi-input with client-side validation that mirrors the backend rules
+  (no `@`, no whitespace, no wildcards, lowercase-only FQDNs). The read-only
+  view renders an explicit "any (no gate configured)" sentinel when the list
+  is empty so operators can tell "not configured" apart from "field is
+  invisible." A "Clear all" button on the edit form is gated by a confirm
+  dialog that warns about removing the tenant gate. **Operator advisory: if
+  you provisioned OIDC providers via the GUI between v2.1.0 and this fix,
+  verify `allowed_email_domains` matches your tenant policy — the field was
+  configurable only via API / MCP / direct SQL during that window.** Per-IdP
+  runbooks for multi-tenant IdPs in `docs/operator/oidc-runbooks/` already
+  documented the field; the GUI now matches.
+
+- **Approval payload preview (Audit 2026-05-11 A-5).**
+  The MED-10 closure claim ("PARTIAL: raw JSON preview; diff library
+  deferred") was inaccurate — `ApprovalsPage.tsx` rendered no payload
+  at all, so approvers were clicking Approve / Reject without seeing
+  the change they were authorizing. That defeats the entire four-eyes
+  primitive: an approver who can't see what they're approving is
+  rubber-stamping. Each row now carries a Preview toggle that expands
+  an inline panel dispatching by kind: `profile_edit` shows a
+  field-level before/after diff (changed-only rows, red/green cells,
+  `(unset)` sentinel for added/removed fields); `cert_issuance` shows
+  a definition list of CN / SANs / profile / key algo / must-staple /
+  validity (catches the wildcard-against-corp-internal-profile attack
+  at review time); unknown kinds render a generic JSON preview for
+  forward-compat with future approval kinds. The base64-encoded JSON
+  payload is decoded via the new `decodePayload` helper; malformed
+  inputs render an explicit decode-error fallback — silent failure on
+  the payload preview is what produced this bug in the first place.
+
+- **Strict pre-login UA/IP binding (Audit 2026-05-11 A-6).**
+  The MED-16 closure left a request-side empty-header bypass: when the
+  pre-login row carried a User-Agent or client-IP binding but the
+  `/auth/oidc/callback` request omitted the corresponding value, the
+  binding check was silently skipped. `curl` doesn't send User-Agent
+  by default; many programmatic clients omit it. An attacker who
+  acquired a pre-login cookie could replay it without the bound
+  header and bypass the RFC 9700 §4.7.1 defense. The check is now
+  strict-when-stored — an empty request-side value with a non-empty
+  stored binding rejects with HTTP 400 and the new audit failure
+  categories `prelogin_ua_missing` / `prelogin_ip_missing` (distinct
+  from the existing `*_mismatch` categories so SIEM rules can alert
+  specifically on bypass attempts). **Operator advisory:** environments
+  where the User-Agent is stripped in transit (some debug proxies, a
+  handful of CDN configurations) must set
+  `CERTCTL_OIDC_PRELOGIN_REQUIRE_UA=false` to keep logins working;
+  symmetric `CERTCTL_OIDC_PRELOGIN_REQUIRE_IP=false` exists for the
+  IP-side. The legacy-row compat window — pre-migration rows with no
+  stored binding — still passes through unchecked, but that window is
+  bounded by the 10-minute pre-login TTL.
+
+- **OIDC provider Advanced fields are now editable in the GUI (Audit 2026-05-11 A-7).**
+  The MED-4 row had been DEFERRED to v3 with the rationale "backend
+  already accepts these fields." The verifier hit the GUI and found
+  that the read-only display claimed the values were editable, but the
+  edit form had no inputs — the save handler passed `provider.scopes`
+  / `provider.groups_claim_path` / `provider.groups_claim_format` /
+  `provider.iat_window_seconds` / `provider.jwks_cache_ttl_seconds`
+  unchanged from the loaded object. Operators who wanted to bump the
+  IAT window or change the groups-claim path had to drop to curl /
+  MCP and trust the GUI's display matched what they'd set elsewhere.
+  Lying UX. The OIDCProviderDetailPage edit form now has a collapsible
+  Advanced section with five inputs (scopes as a space-separated text
+  field; groups-claim path; groups-claim format select with the
+  backend's `string-array` / `json-path` enum; IAT window number input
+  bounded 1–600; JWKS cache TTL number input with floor 60). Client-side
+  validation mirrors the backend `Validate` rules so common operator
+  mistakes (IAT > 600, JWKS TTL < 60, empty scopes, empty groups-claim-path)
+  reject inline instead of round-tripping a 400. The read-only `<dl>`
+  also gained the previously-invisible `jwks_cache_ttl_seconds` row.
+
+- **Pre-login cookie Path widened from `/auth/oidc/` to `/` (Audit MED-14
+  follow-on).** Required to satisfy the `__Host-` prefix's `Path=/` rule. The
+  cookie lifetime is unchanged (10 minutes) and only the callback handler
+  consumes it; the wider path scope is harmless.
+
+- **RFC 9207 `iss` URL parameter check on OIDC callback (Audit 2026-05-10
+  MED-17).** When the matched IdP's discovery doc advertises
+  `authorization_response_iss_parameter_supported: true`, certctl now requires
+  the `iss` query parameter on `/auth/oidc/callback` and enforces a
+  constant-time compare against the configured provider's `IssuerURL`. Mismatch
+  rejects with HTTP 400; the audit row's `failure_category` distinguishes
+  `iss_param_missing` / `iss_param_mismatch` (RFC 9207 leg) from the existing
+  `id_token_iss_mismatch` (in-token iss claim leg). Closes the mix-up-attack
+  defense for modern Keycloak, Authentik, and public-trust CAs that ship
+  RFC-9207 discovery. Providers that don't advertise support (the majority
+  today) keep pre-fix behavior — back-compat is preserved.
+
+- **Auth GUI batch (Audit 2026-05-10 MED-4/7/8/10/11/12 + LOW-1/11/12 +
+  HIGH-10 GUI).** New backend endpoints land alongside their GUI
+  consumers: `GET /api/v1/auth/users` + `DELETE /api/v1/auth/users/{id}`
+  (auth.user.read / auth.user.deactivate; migration 000045 adds
+  `users.deactivated_at` plus the two new permissions); `GET
+  /api/v1/auth/runtime-config` (auth.role.assign) returning a sanitized
+  flat-map of deployed CERTCTL_* values (no secrets leaked — only
+  set/unset booleans and counts); `GET
+  /api/v1/auth/oidc/providers/{id}/jwks-status` (auth.oidc.list)
+  returning the per-provider verifier counters (refresh count, last
+  refresh / error timestamps, rejected JWS count, RFC 9207 iss-param
+  flag). New `UsersPage` lists federated identities + soft-deactivates.
+  `AuthSettingsPage` gains the runtime-config panel. `KeysPage`'s
+  assign-role modal now collects `scope_type` / `scope_id` /
+  `expires_at`. `RoleDetailPage`'s add-permission form gains the same
+  scope picker, and the Delete button is hidden on the 7 default
+  system roles (server already rejected, this is pure UX).
+  `AuthProvider` renders a sticky red demo-mode banner when
+  `auth_type=none`. `actor-demo-anon` rows on `KeysPage` already had
+  buttons disabled.
+
+- **11 new MCP tools (Audit 2026-05-10 MED-13).** Approval workflow
+  (`certctl_approval_list` / `_get` / `_approve` / `_reject`), break-glass
+  credential admin (`certctl_breakglass_list` / `_set_password` /
+  `_unlock` / `_remove`), bootstrap status + consume
+  (`certctl_bootstrap_status` / `_consume`), and audit category filter
+  (`certctl_audit_list_with_category`). All route through the existing
+  HTTP client so server-side permission gates fire unchanged.
+  `certctl_bootstrap_consume`'s tool description carries an explicit
+  "NEVER WIRE THIS TO AUTONOMOUS OPERATION" warning — a leaked
+  bootstrap token mints a fresh admin API key bypassing every other
+  access-control gate, so the tool is for one-shot manual operator
+  invocation only.
+
+- **JWKS auto-refresh on cache-miss (Audit 2026-05-10 MED-6).** When
+  the IdP rotates its signing key between pre-login + callback, the
+  cached JWKS no longer contains the kid referenced by the inbound ID
+  token's JWS header. Pre-fix, the verify failed with a generic error
+  and the operator had to manually call `POST
+  /api/v1/auth/oidc/providers/{id}/refresh`. The service now detects
+  the kid-not-in-cache shape (`isKidMismatchError`) and runs a
+  one-shot `RefreshKeys` (evict cache → re-fetch discovery + JWKS →
+  re-run alg-downgrade defense) before retrying the verify exactly
+  once. Bounded recovery: a second failure surfaces as
+  `ErrJWKSUnreachable` per the original branches; no retry loop. A
+  separate matcher (`isKidMismatchError`) is intentionally narrow
+  so generic signature failures don't trigger refresh.
+
+- **OIDC provider test endpoint (Audit 2026-05-10 MED-5).** New
+  `POST /api/v1/auth/oidc/test` dry-runs an OIDC provider configuration
+  without persisting: fetches the discovery doc, runs the alg-downgrade
+  defense, detects RFC 9207 iss-parameter advertisement, and confirms
+  JWKS reachability. Returns `TestDiscoveryResult{discovery_succeeded,
+  jwks_reachable, supported_alg_values, iss_param_supported, errors[]}`
+  so the GUI (forthcoming) can render per-check status rows. Per-leg
+  failures ride in the response body's `errors` array; only a malformed
+  request body trips 400. Gate: `auth.oidc.create`. Audit row
+  `auth.oidc_provider_tested` carries the success/failure summary.
+
+- **Pre-login UA / source-IP binding on OIDC callback (Audit 2026-05-10
+  MED-16).** RFC 9700 §4.7.1 defense against stolen-pre-login-cookie replay
+  by a different browser / source. Migration `000044_prelogin_uaip` adds
+  `client_ip` + `user_agent` to `oidc_pre_login_sessions`; values captured at
+  `/auth/oidc/login` are constant-time compared at `/auth/oidc/callback`.
+  Mismatches return HTTP 400 with audit `failure_category` =
+  `prelogin_ua_mismatch` or `prelogin_ip_mismatch`. Two operator escape
+  hatches: `CERTCTL_OIDC_PRELOGIN_REQUIRE_UA` and
+  `CERTCTL_OIDC_PRELOGIN_REQUIRE_IP` (both default `true`) — operators on
+  enterprise proxies that rewrite UA, or dual-stack v4/v6 environments where
+  source IP routinely flips, can disable the affected leg. The binding column
+  is persisted even when enforcement is off, so retroactive forensics remain
+  possible. Empty values on either side pass through (rolling-deploy +
+  headless-proxy compat).

-  master.** Roadmap entry remains in `cowork/auth-bundle-2-prompt.md`.
+  Auth Bundle 2 ships in the same v2.1.0 release. Operators get OIDC
+  SSO support for Keycloak / Authentik / Okta / Auth0 / Microsoft
+  Entra ID / Google Workspace (via Keycloak broker), HMAC-signed
+  session cookies with idle/absolute timeouts + CSRF defense,
+  back-channel logout per OpenID Connect Back-Channel Logout 1.0,
+  and a default-OFF break-glass admin path with Argon2id passwords
+  for SSO-broken incidents. API-key auth keeps working unchanged
+  alongside; existing automation needs no changes. Migration walkthrough
+  at [`docs/migration/oidc-enable.md`](docs/migration/oidc-enable.md);
+  per-IdP setup guides at
+  [`docs/operator/oidc-runbooks/index.md`](docs/operator/oidc-runbooks/index.md).
+- **OIDC token validation pinned at three layers.** Algorithm
+  allow-list (RS256/RS512/ES256/ES384/EdDSA only) with HS-family + `none`
+  rejected at the service-layer sentinel; IdP-downgrade-attack defense
+  at provider creation AND every JWKS RefreshKeys (intersects the IdP's
+  advertised `id_token_signing_alg_values_supported` against the allow-
+  list, rejects providers that advertise weak algs even before any
+  token is signed); OIDC Core §3.1.3.7 re-verification of `iss` /
+  `aud` / `azp` / `at_hash` (REQUIRED-when-access_token-present per
+  Phase 3 tightening of the spec MAY → MUST) / `exp` / `iat` window
+  / `nonce` constant-time-compare. PKCE-S256 mandatory; `plain`
+  rejected. Single-use state + nonce via atomic `DELETE...RETURNING`
+  on consume.
+- **Session cookies use length-prefixed HMAC.** The cookie wire format
+  is `v1.<session_id>.<signing_key_id>.<base64url-no-pad(HMAC-SHA256)>`
+  with HMAC input `len:sid:len:kid` (NOT bare-concat) to defeat
+  concatenation collisions. `HttpOnly` + `Secure` + `SameSite=Lax`
+  default; `SameSite=Strict` configurable via `CERTCTL_SESSION_SAMESITE`.
+  Idle timeout 1h / absolute 8h defaults; scheduler GC sweeps expired
+  rows hourly. Signing keys rotate via the new `RotateSigningKey`
+  primitive; the old key stays valid for `CERTCTL_SESSION_SIGNING_KEY_RETENTION`
+  (default 24h) so existing cookies validate during rollover.
+- **CSRF defense via double-submit-cookie + hashed-token-on-row.**
+  Plaintext CSRF token in the JS-readable `certctl_csrf` cookie
+  (intentionally `HttpOnly=false` for the GUI to echo into the
+  `X-CSRF-Token` header); SHA-256 hash on the session row;
+  `subtle.ConstantTimeCompare` in the new `CSRFMiddleware`. API-key
+  actors are CSRF-exempt (no session row in context).
+- **OIDC `client_secret` encrypted at rest.** AES-256-GCM v3 blob
+  format (magic 0x03 + salt(16) + nonce(12) + ciphertext+tag) using
+  the existing `CERTCTL_CONFIG_ENCRYPTION_KEY`. Encryption invariant
+  pinned by an integration test asserting ciphertext != plaintext +
+  v3 blob shape + round-trip recovery + wrong-passphrase fails.
+- **OIDC first-admin bootstrap.** New `CERTCTL_BOOTSTRAP_ADMIN_GROUPS`
+  + `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID` env vars: the first
+  OIDC-authenticated user with a matching group claim becomes admin
+  per tenant. Coexists with the Bundle 1 env-var-token bootstrap;
+  the admin-existence probe ensures only one wins. Audit row
+  (`bootstrap.oidc_first_admin`) on every grant.
+- **Break-glass admin (default-OFF).** New `CERTCTL_BREAKGLASS_ENABLED`
+  env var (default `false`). When enabled, the local Argon2id-password
+  admin path bypasses OIDC + group-claim layers — intended ONLY for
+  SSO-broken incidents. Argon2id with OWASP 2024 params (m=64 MiB,
+  t=3, p=4); lockout after 5 failures (configurable); constant-time
+  across all failure paths via `verifyDummy`; surface invisibility
+  (HTTP 404 on every endpoint when disabled, NOT 403). WARN log at
+  server boot when enabled. WebAuthn/FIDO2 second factor pairing on
+  the v3 roadmap (Decision 12).
+- **GUI: OIDC Providers + Group → Role Mappings + Sessions + login
+  buttons.** Four new pages under `/auth/*` consume the Bundle 2 API
+  surface. Login page renders one "Sign in with X" button per
+  configured OIDC provider (in addition to the API-key form, which
+  remains as a fallback for Bearer-mode + break-glass paths). Sessions
+  page exposes own-sessions + admin all-actors view. Every actionable
+  element is permission-gated server-side via `auth.oidc.*` and
+  `auth.session.*` perms; client-side hide is UX layer. Logout button
+  in the sidebar fires `POST /auth/logout` to clear the session
+  server-side before redirecting to login.
+- **MCP server gains 11 OIDC + session tools.** `certctl_auth_list_oidc_providers`,
+  `_get_oidc_provider`, `_create_oidc_provider`, `_update_oidc_provider`,
+  `_delete_oidc_provider`, `_refresh_oidc_provider`,
+  `_list_group_mappings`, `_add_group_mapping`, `_remove_group_mapping`,
+  `_list_sessions`, `_revoke_session`. Operator-facing MCP tool count
+  goes 12 (Bundle 1 RBAC) → 23 across the auth surface. Total MCP
+  tool count: `grep -cE 'mcp\.AddTool\(' internal/mcp/tools*.go` ≈ 150.
+- **Per-IdP runbooks: 6 production-tier setup guides** at
+  `docs/operator/oidc-runbooks/`. Each runbook follows a consistent
+  five-section layout (Prerequisites / IdP-side config / certctl-side
+  config / Verification / Troubleshooting + Validation checklist with
+  operator sign-off line). Keycloak is the canonical reference;
+  Authentik / Okta / Auth0 / Entra ID / Google Workspace document the
+  IdP-specific deltas (Auth0's namespaced custom claims; Entra ID's
+  group OBJECT IDs; Google Workspace's missing-groups-claim limitation
+  + the recommended Keycloak broker pattern).
+- **Threat model extended.** [`docs/operator/auth-threat-model.md`](docs/operator/auth-threat-model.md)
+  ships 5 new "Defenses Bundle 2 ships" subsections + 8 new threat-
+  catalogue subsections (OIDC token forgery / session hijacking / IdP
+  compromise / back-channel logout failure modes / group-claim
+  manipulation / bootstrap risks / break-glass risks / token-leak
+  hygiene). 6 new SQL-shaped operator-facing checks. New "Threats
+  Bundle 2 does NOT close" section enumerating the 8 v3-backlog items
+  (WebAuthn / JIT elevation / SAML / multi-tenant activation /
+  HSM-FIPS / OIDC RP-initiated logout / Playwright / per-IdP
+  external-tester sign-off).
+- **Performance baselines documented.** [`docs/operator/auth-benchmarks.md`](docs/operator/auth-benchmarks.md)
+  ships four benchmarks with measured baselines on a 4 vCPU /
+  8 GiB / Postgres 16 / Go 1.25 floor: `BenchmarkSession_SteadyState`
+  p99 5 µs (target < 1 ms; 200× under), `BenchmarkSession_ColdProcess`
+  p99 7.1 ms (target < 10 ms), `BenchmarkOIDC_SteadyState` p99 1.5 ms
+  (target < 5 ms), `BenchmarkOIDC_ColdCache` operator-runs against
+  live Keycloak via `make benchmark-auth-coldcache`.
+- **Standards + RFC implementation table.** [`docs/reference/auth-standards-implemented.md`](docs/reference/auth-standards-implemented.md)
+  ships 13 RFC / standard rows + 14 CWE rows with concrete file paths
+  + negative-test anchors per row. NOT a compliance-mapping doc per
+  the operator's 2026-05-05 retired-compliance-docs decision; the
+  doc explicitly says "build the framework mapping yourself against
+  the rows here using the framework-mapping methodology your audit
+  firm prescribes; this project does not own that mapping."
+- **Coverage gates held at floor 90 across all four Bundle 2
+  packages.** `internal/auth/oidc/` 93.7%, `internal/auth/session/`
+  94.9%, `internal/auth/breakglass/` 91.5%, `internal/auth/user/domain/`
+  96.4%. NO held-low-with-rationale entry — the Phase 13 prompt's
+  anti-Bundle-1-mistake rule held. Bundle 1's existing 85% floors
+  for `internal/auth/` + `internal/service/auth/` stay 85
+  (already-shipped-and-accepted) per the prompt's explicit
+  inheritance rule.
+- **Multi-tenant query CI guard.** New `scripts/ci-guards/multi-tenant-query-coverage.sh`
+  (ratchet-style, baseline 32 at v2.1.0 close): greps every
+  SELECT/UPDATE/DELETE in `internal/repository/postgres/` against
+  10 tenant-aware tables, fails on regression OR improvement (forces
+  the operator to lift / lower the baseline visibly). Forward-compat
+  protection so a future Bundle 3 / managed-service multi-tenant
+  activation can flip the switch without finding silent
+  tenant-data-leak bugs in shipped queries.
+- **Phase 10 Keycloak testcontainers integration test.** New build-tag-
+  gated suite at `internal/auth/oidc/testfixtures/` + `integration_keycloak_test.go`
+  drives the full OIDC flow against a live Keycloak container booted
+  by testcontainers-go. 5-test matrix: discovery + JWKS load, full
+  PKCE auth-code happy path with HTTP form scraping, logout-revokes-
+  session, JWKS rotation, unmapped-groups-fails-closed. Reuses one
+  container across the matrix to amortize the 60-90s boot. Optional
+  Okta smoke test (build-tagged `integration && okta_smoke`) for live
+  tenant validation. New Makefile targets: `make keycloak-integration-test`
+  + `make okta-smoke-test` + `make benchmark-auth-coldcache`.
+- **OpenAPI surface extended.** New `cookieAuth` security scheme
+  (apiKey/cookie/`certctl_session`) alongside the existing
+  `bearerAuth`. 13 new Bundle 2 endpoints across the OIDC + session
+  + group-mapping CRUD surface; 4 break-glass endpoints with
+  surface-invisibility framing. The N-bundle-2-security-empty-preserved
+  CI guard locks the `security: []` opt-out count at ≥ 14 so existing
+  public endpoints stay public.
+- **Bundle-1-only compat regression CI guard.** New
+  `scripts/ci-guards/bundle-1-compat-regression.sh` asserts the
+  load-bearing invariants that protect the Bundle-1-only-deploy
+  case (session middleware defers-to-next, CSRF passthrough on
+  missing session row, ChainAuthSessionThenBearer wired, public
+  OIDC routes in AuthExempt allowlist, AuthInfo guards on
+  OIDCProvidersResolver != nil). Sibling
+  `bundle-1-to-2-upgrade-regression.sh` asserts the upgrade-path
+  invariants (migrations 000034..000038 are CREATE TABLE IF NOT EXISTS
+  + BEGIN/COMMIT-wrapped + no DROP TABLE / ALTER...DROP COLUMN
+  against 19 protected Bundle-1 tables + ON CONFLICT DO NOTHING on
+  permission seed).

-certctl is a self-hosted platform that automates the entire TLS certificate lifecycle, from issuance through renewal to deployment, with zero human intervention. It works with any certificate authority, deploys to any server, and keeps private keys on your infrastructure where they belong. Free, source-available under BSL 1.1, covers the same lifecycle that enterprise platforms charge $100K+/year for.
+certctl is a self-hosted platform that automates the entire TLS certificate lifecycle, from issuance through renewal to deployment, with zero human intervention. Twelve native CA connectors plus an OpenSSL / shell-script adapter for custom CAs; fourteen production-ready native deployment-target connectors plus Kubernetes Secrets (preview) and a proxy-agent pattern for network appliances and agentless targets. In agent-mode (the default), private keys stay on the host they were generated on and never touch the control plane; a demo-only `CERTCTL_KEYGEN_MODE=server` flag mints keys server-side, refuses to start without an explicit `CERTCTL_DEMO_MODE_ACK=true` acknowledgement. Free, source-available under BSL 1.1, covers the same lifecycle that enterprise platforms charge $100K+/year for.
 
 The CA/Browser Forum's [Ballot SC-081v3](https://cabforum.org/2025/04/11/ballot-sc081v3-introduce-schedule-of-reducing-validity-and-data-reuse-periods/) caps public TLS certificates at **200 days by March 2026**, **100 days by 2027**, and **47 days by 2029**. At 47-day lifespans, a team managing 100 certificates is processing 7+ renewals per week, every week, forever. Manual workflows stop being a choice.
 
-> **Status: Early-access.** Production-quality core (Local CA, ACME, agent deployment, CRUD, audit, [role-based authz](docs/operator/rbac.md) with auditor split + day-0 bootstrap + four-eyes approval) with broader feature surface (intermediate CA hierarchy, ACME/SCEP/EST servers, network appliances) still maturing. [Federated identity](docs/operator/auth-threat-model.md#threats-bundle-1-does-not-close) (OIDC/SAML/WebAuthn, server-side sessions, break-glass accounts, JIT elevation) is the next slice on the roadmap, not yet shipped. Lab and dev deployments encouraged; production deployments welcome with the understanding that customer-scale battle-testing is in progress. File GitHub issues for any rough edges.
+> **Status: Early-access — actively looking for design partners.**
+
+> The certificate lifecycle core is production-quality today: Local CA, ACME, agent deployment, audit, [role-based access control](docs/operator/rbac.md) with auditor split and four-eyes approval. v2.1.0 adds federated identity on top — [OIDC SSO](docs/operator/oidc-runbooks/index.md), server-side sessions, back-channel logout, and a break-glass admin path for SSO-outage recovery.
+
+> If your team runs PKI infrastructure that could use real automation, we'd love to have you on certctl. Lab and dev deployments are great. Production is welcome too — especially on the federated-identity surface, where real-world IdP shapes are exactly the exposure we can't manufacture in CI. Battle-testing certctl in your environment is genuinely valuable to us.
+
+> [File issues](https://github.com/certctl-io/certctl/issues) liberally. Every IdP quirk, every connector edge, every doc gap you hit — that's how the platform earns the right to drop the "early-access" label. The faster the loop, the faster everyone benefits.
 
 > **Actively maintained, shipping weekly.** [Open an issue](https://github.com/certctl-io/certctl/issues) if something breaks. CI runs the full test suite with race detection, static analysis, and vulnerability scanning on every commit.

 certctl handles the full certificate lifecycle in one self-hosted control plane:
 
 - **Issue and renew** from any CA. Let's Encrypt and any ACME provider, an embedded ACME server you can point cert-manager / certbot / lego at directly, a built-in local CA with sub-CA mode (chains under your enterprise root like ADCS), step-ca, Vault PKI, EJBCA, AWS ACM PCA, Google CAS, DigiCert, Sectigo, GlobalSign, Entrust, plus an OpenSSL / shell-script adapter for anything custom. Twelve native issuer connectors. See the [connector reference](docs/reference/connectors/index.md).
-- **Deploy automatically** to NGINX, Apache, HAProxy, Caddy, Traefik, Envoy, IIS, Windows Cert Store, Java keystore, Kubernetes Secrets, AWS ACM, Azure Key Vault, SSH known-hosts, Postfix + Dovecot, F5 BIG-IP. Fifteen native target connectors. Every deploy goes through atomic-write + ownership-preservation + SHA-256 idempotency + per-target Prometheus counters + pre-deploy snapshot + on-failure rollback. See [`docs/reference/deployment-model.md`](docs/reference/deployment-model.md).
+- **Deploy automatically** to NGINX, Apache, HAProxy, Caddy, Traefik, Envoy, IIS, Windows Cert Store, Java keystore, AWS ACM, Azure Key Vault, SSH known-hosts, Postfix + Dovecot, F5 BIG-IP. **Fourteen production-ready native target connectors plus Kubernetes Secrets (preview).** File-based targets share an atomic-write + SHA-256 idempotency + on-failure rollback + per-target Prometheus counters primitive (the `deploy.Apply` path covers 12 of 13 file-based connectors). Cloud / API targets (AWS ACM, Azure Key Vault) use vendor-SDK semantics rather than the file primitive; F5 uses iControl REST transactions. The Kubernetes Secrets connector is shipped as preview because the production `client-go` integration is incomplete — see [`docs/reference/deployment-model.md`](docs/reference/deployment-model.md) for the per-target guarantee matrix. The reload / validate commands operators configure for shell-using targets (NGINX, Apache, HAProxy, Postfix, JavaKeystore, SSH) are validated server-side AND agent-side against shell-metacharacter injection before execution (see [`internal/connector/target/configcheck`](internal/connector/target/configcheck)).
 - **Run as an ACME server** so existing client tooling plugs in directly. RFC 8555 + RFC 9773 ARI, two per-profile auth modes (public-trust-style validation or trust_authenticated for internal PKI), doubly-signed key rollover, revoke-cert on both kid path and jwk path, per-account rate limiting. Cert-manager / certbot / lego all work pointed at it. See [`docs/reference/protocols/acme-server.md`](docs/reference/protocols/acme-server.md).
 - **Run as a SCEP server** for Microsoft Intune-managed phones, ChromeOS devices, network appliances. RFC 8894 native with full PKIMessage wire format, native Intune challenge dispatch with replay protection, per-profile dispatch with separate RA cert per profile. See [`docs/reference/protocols/scep-server.md`](docs/reference/protocols/scep-server.md).
 - **Run as an EST server** for HTTPS-based PKCS#10 enrollment. 802.1X / Wi-Fi authentication, IoT device enrollment, RFC 9266 channel binding. See [`docs/reference/protocols/est.md`](docs/reference/protocols/est.md).
 - **Manage multi-level CA hierarchies** with name constraints, path-length enforcement, and end-to-end RFC 5280 path validation. Root → intermediate → issuing chains, admin-gated CRUD, drain-first retirement. Patterns documented for 4-level boundary CAs, 3-level policy CAs with per-BU `PermittedDNSDomains`, and 2-level internal PKI. See [`docs/reference/intermediate-ca-hierarchy.md`](docs/reference/intermediate-ca-hierarchy.md).
 - **Gate high-stakes issuance** behind two-person-integrity approval. Flag a profile as `RequiresApproval`, the request lands in a queue, a non-requester approves, the scheduler dispatches. Profile-edit changes on approval-tier profiles route through the same gate so the flip-flop bypass is closed. See [`docs/operator/approval-workflow.md`](docs/operator/approval-workflow.md).
-- **Authorize with role-based access control.** Seven default roles (admin, operator, viewer, agent, mcp, cli, auditor) over a 33-permission canonical catalogue with global / per-profile / per-issuer scope. Auditor role is read-only on the audit trail (`audit.read` + `audit.export`, nothing else) so a regulator's key cannot read certificates or mutate config. Day-0 admin via a one-shot `CERTCTL_BOOTSTRAP_TOKEN` endpoint that closes itself the moment any admin lands. Privilege-escalation guard requires `auth.role.assign` to grant or revoke a role. See [`docs/operator/rbac.md`](docs/operator/rbac.md), [`docs/operator/auth-threat-model.md`](docs/operator/auth-threat-model.md), and the v2.0.x → v2.1.0 [migration guide](docs/migration/api-keys-to-rbac.md).

+- **Sign in with OIDC SSO** against any standards-compliant identity provider. Per-IdP setup runbooks for Keycloak, Authentik, Okta, Auth0, Microsoft Entra ID, and Google Workspace. Group-claim → role mapping for automatic provisioning; client_secret encrypted at rest (AES-256-GCM); JWKS auto-refresh on `kid` miss; PKCE-S256 required; RFC 9700 §4.7.1 pre-login UA/IP binding; RFC 9207 `iss` URL-param check on callback. Server mints HMAC-signed session cookies with the `__Host-` prefix (browser-enforced subdomain-takeover defense), CSRF rotation on every privileged write, and idle + absolute expiry. [RFC OIDC Back-Channel Logout 1.0](docs/reference/auth-standards-implemented.md) revokes sessions on IdP-driven logout. Argon2id break-glass admin path for SSO-outage recovery — disabled by default; 404-invisible to scanners when `CERTCTL_BREAKGLASS_ENABLED=false`. See [`docs/operator/oidc-runbooks/index.md`](docs/operator/oidc-runbooks/index.md) for the per-IdP onboarding guides and [`docs/migration/oidc-enable.md`](docs/migration/oidc-enable.md) for enabling SSO on an existing deploy.
 - **Discover** existing certs across your fleet via filesystem scanning on agents, network TLS probing across CIDR ranges, and cloud secret manager imports (AWS Secrets Manager, Azure Key Vault, GCP Secret Manager). Triage workflow for claim / dismiss / investigate.
 - **Revoke** with full RFC 5280 reason codes, DER CRL generation per issuer (scheduler-pre-generated and ETag-cached), and an embedded RFC 6960 OCSP responder with dedicated per-issuer responder certs. Single + bulk revocation. See [`docs/reference/protocols/crl-ocsp.md`](docs/reference/protocols/crl-ocsp.md).
 - **Alert** via Slack, Microsoft Teams, PagerDuty, OpsGenie, email, webhooks. Per-policy multi-channel routing matrix with severity tiers and fault-isolating per-channel dispatch. See [`docs/operator/runbooks/expiry-alerts.md`](docs/operator/runbooks/expiry-alerts.md).
-- **Drive the platform from natural language** via the bundled MCP (Model Context Protocol) server. The full REST API is exposed as MCP tools — ask your AI client "show me all expiring certificates", "revoke the VPN cert, key compromised", or "what agents are offline?" and it translates to API calls. Stateless stdio-transport binary at `cmd/mcp-server/`; same auth as the REST API; no extra attack surface. See [`docs/reference/mcp.md`](docs/reference/mcp.md).

MCP-vs-REST parity (162 tools covering 221 routes; the gap is a small allowlist of streaming + protocol-conformance endpoints that don't fit the request-response tool shape) is tracked in [`docs/reference/mcp-coverage.md`](docs/reference/mcp-coverage.md) with a CI guard that fails the build if a new REST route lands without either an MCP tool or an explicit allowlist entry.

 ## Architecture and security
 
-Go 1.25 control plane with handler → service → repository layering. PostgreSQL 16 backend (35+ tables, idempotent migrations). Pull-only deployment model — the server never initiates outbound connections. Agents poll for work and generate ECDSA P-256 keys locally so private keys never touch the control plane. For network appliances and agentless servers, a proxy agent in the same network zone handles deployment via the target's API (WinRM, iControl REST, SSH/SFTP). See the [Architecture Guide](docs/reference/architecture.md) for full system diagrams.

 ## Quick Start
 
 ### Docker Compose (recommended)
 
+**Demo path — zero config, populated dashboard:**
+
 ```bash
 git clone https://github.com/certctl-io/certctl.git
 cd certctl
-docker compose -f deploy/docker-compose.yml -f deploy/docker-compose.demo.yml up -d --build
+./deploy/demo-up.sh -d --build
 ```
 
-Wait ~30 seconds, then open **https://localhost:8443** in your browser. The shipped demo overlay seeds 32 certificates across 10 issuers, 8 agents, and 180 days of realistic history. The `certctl-tls-init` init container self-signs an ECDSA-P256 cert on first boot — accept the browser warning for the demo, or feed the generated `ca.crt` to your client.
+Wait ~30 seconds, then open **https://localhost:8443** in your browser. The `demo-up.sh` wrapper exports a fresh `CERTCTL_DEMO_MODE_ACK_TS=$(date +%s)` and forwards the remaining args to `docker compose -f docker-compose.yml -f docker-compose.demo.yml up`. The timestamp export is required by the Phase 2 SEC-H3 fail-closed guard in `internal/config/config.go::Validate` — demo deploys must re-ACK every 24h so a forgotten demo container never silently ends up serving production traffic with `auth-type=none`. The bare `docker compose ... up` command without the timestamp refuses to boot; the wrapper script is the supported entry point.
 
-For a clean install without demo data, drop the `-f deploy/docker-compose.demo.yml` flag and run `docker compose -f deploy/docker-compose.yml up -d --build`. The four compose files (`docker-compose.yml` base, `docker-compose.demo.yml` overlay, `docker-compose.dev.yml` for PgAdmin + debug logging, `docker-compose.test.yml` for integration tests) are documented at [`deploy/ENVIRONMENTS.md`](deploy/ENVIRONMENTS.md).
+The demo overlay flips the base into demo-mode auth (every request served as the synthetic admin actor `actor-demo-anon` — the server emits a prominent ⚠ DEMO MODE banner at boot reminding you this posture is for evaluation only) and seeds 180 days of realistic history across 13 issuers, 8 agents, managed + discovered certs, jobs, deploys, audit, and notification events. The `certctl-tls-init` init container self-signs an ECDSA-P256 cert on first boot — accept the browser warning for the demo, or feed the generated `ca.crt` to your client.
+
+**Production path — `.env` required, fail-closed on placeholders:**
+
+```bash
+cp .env.example deploy/.env       # or root .env if running outside compose
+"${EDITOR:-nano}" deploy/.env     # set POSTGRES_PASSWORD, CERTCTL_AUTH_SECRET,
+                                   # CERTCTL_API_KEY, CERTCTL_CONFIG_ENCRYPTION_KEY,
+                                   # CERTCTL_AGENT_ID — all via openssl rand
+                                   # (replace nano with your preferred editor)
+docker compose -f deploy/docker-compose.yml up -d --build
+```
+
+The base compose alone (no demo overlay) ships production-shaped: default `auth-type=api-key`, default `keygen-mode=agent`, no demo seed, no demo-mode synthetic admin. The fail-closed startup guards in `internal/config/config.go::Validate` refuse to boot when any of the change-me-... placeholder credentials reach config outside of demo mode (Bundle 2 closure, 2026-05-12). The four compose files (`docker-compose.yml` base, `docker-compose.demo.yml` overlay, `docker-compose.dev.yml` for PgAdmin + debug logging, `docker-compose.test.yml` for integration tests) are documented at [`deploy/ENVIRONMENTS.md`](deploy/ENVIRONMENTS.md).

+## Test-fixture-only dependencies
+
+**Cisco libest.** The certctl integration test suite exercises the EST
+(RFC 7030) endpoints against Cisco's libest reference client. libest
+runs as a sidecar container (`certctl-test-libest`) only when the
+`est-e2e` Docker Compose profile is active — it is **not** vendored
+into the certctl source tree and **not** linked into any distributed
+release artifact (server, agent, CLI, MCP-server, container images,
+or release tarballs). For libest's own license terms, see
+<https://github.com/cisco/libest>.
+
+**f5-mock-icontrol.** The F5 deployment-target integration test
+ships a small Go program at `deploy/test/f5-mock-icontrol/main.go`
+under the same BSL 1.1 license as the rest of certctl. The compiled
+ELF was removed from the tracked tree in Phase 1 closure (commit
+eda3b48, 2026-05-13); it now rebuilds via the Dockerfile's
+multi-stage build on demand.

+// This file holds the DEPLOYMENT executor + the target connector
+// factory + the deploy-only helpers:
+//
+//   - executeDeploymentJob: handles Pending deployment jobs by
+//     fetching the cert PEM from the control plane, loading the
+//     locally-held private key (in agent keygen mode), instantiating
+//     the appropriate target connector via createTargetConnector,
+//     calling DeployCertificate on it, and reporting Completed or
+//     Failed back to the control plane.
+//   - createTargetConnector: the big switch over target_type that
+//     instantiates one of 14 target connectors (apache / awsacm /
+//     azurekv / caddy / envoy / f5 / haproxy / iis / javakeystore /
+//     k8ssecret / nginx / postfix / ssh / traefik / wincertstore).
+//     Context is threaded into SDK-driven connectors (AWSACM,
+//     AzureKeyVault) so credential resolution honors caller
+//     cancellation per the contextcheck linter — see CI commit
+//     502823d.
+//   - splitPEMChain: split a PEM chain into (first cert, rest).
+//   - fetchCertificate: pull the PEM chain from
+//     GET /api/v1/certificates/{certID}/version.
+//
+// All 14 target-connector imports were used ONLY by
+// createTargetConnector; moving the factory here also moved the
+// 14 connector imports out of main.go, leaving the surviving
+// cmd/agent/main.go with the minimal stdlib surface its lifecycle
+// + HTTP infrastructure needs.

+//     seed completed cleanly. The caller (main) translates that to
+//     `return` rather than os.Exit(0) — which is the SOLE intentional
+//     behavior change in this sprint (see below).
+//
+// Behavior preservation contract
+// ==============================
+// Every error path inside runBootMigrations calls os.Exit(1)
+// directly, matching the original inline behavior byte-for-byte
+// (same log message, same exit code, same no-defer-run-on-fatal
+// semantics). The error-path os.Exit(1) is intentional: when
+// migration fails at boot, the server cannot recover, and bailing
+// out without running defers is the original Go-idiomatic shape.
+//
+// The ONE behavior change: the --migrate-only SUCCESS path now
+// returns to main() rather than calling os.Exit(0) inline. This
+// has one observable effect: the `defer db.Close()` registered in
+// main() now runs at clean exit instead of being skipped. That's
+// strictly better hygiene (clean DB connection shutdown vs OS
+// reclaim). The migration work is synchronous + complete before
+// the return; nothing async is left running that db.Close() could
+// truncate.
+//
+// All other paths — the migration log messages, the seed log
+// messages, the migrationsViaHook env-var read order, the
+// RunDemoSeed gating, the per-step success/skip log lines — are
+// byte-identical to the pre-Sprint-8b inline form. Verified via
+// `go test ./cmd/server/... -count=1 -short` (which runs the
+// existing main_test.go assertions through the new call site).
+//
+// Why this is a separate commit
+// =============================
+// Sprint 8a (commit see git log) extracted the bottom-of-file
+// helpers + adapter types — pure mechanical relocation that
+// couldn't change runtime semantics. Sprint 8b crosses the boundary
+// where mechanical relocation ends: introducing a new function
+// call frame changes defer scope, panic recovery, and (in this
+// case) the exit semantics for the --migrate-only path. The
+// Phase 9 prompt's "refactor is mechanical relocation; behavior
+// change is a separate concern" rule guards against exactly this
+// shape of risk being landed without a focused review.
+//
+// Splitting Sprint 8a (mechanical) from Sprint 8b (behavior-aware)
+// means the operator's git log shows:
+//   3f1344e8 ... wire.go         — no behavior change possible
+//   <this>   ... migrations.go    — one specific behavior shift,
+//                                   documented + intentional
+//
+// Anyone bisecting a future bug to one of these two commits gets a
+// clean "is it mechanical or did the behavior change" signal.
+
+// parseMigrateOnlyFlag scans os.Args for the `--migrate-only` token
+// and returns true if found. Hand-parsed instead of using flag.Parse
+// because:
+//
+//  1. The server's entire config surface is env-var driven via
+//     config.Load(). flag.Parse() introduces a global package-state
+//     dependency that future binaries importing cmd/server (test
+//     harnesses, CLI tools, embedded variants) would have to
+//     coordinate around.
+//  2. The only flag we care about is the migration-vs-server-lifecycle
+//     toggle; a hand-parser is 6 lines and has no transitive cost.
+//  3. The flag is Helm-pre-install-hook-facing (see
+//     deploy/helm/certctl/templates/migration-job.yaml). Its shape is
+//     pinned by that template, not by anything else; we don't need
+//     flag.Parse's auto-help generation or type coercion.
+//

+// the move is by FUNCTIONAL CONCERN (boot-time preflight + DI
+// adapter wiring), not by TYPE FAMILY.
+//
+// Sprint 8 ships TWO of the three files the Phase 9 prompt names:
+//   - main.go      — entrypoint (unchanged; what's left after the cut)
+//   - wire.go      — this file (DI assembly: preflight helpers +
+//                    adapter types that bridge package boundaries)
+//
+// The third file the prompt names — migrations.go — is NOT in this
+// commit. See "What's NOT in this sprint" below for the deferral
+// rationale.
+//
+// What lives here
+// ===============
+// Seven preflight + DI helper functions:
+//   - preflightSCEPChallengePassword   (H-2 fix: SCEP needs non-empty
+//                                       shared secret if enabled)
+//   - preflightSCEPMTLSTrustBundle     (SCEP Phase 6.5: per-profile
+//                                       mTLS CA bundle validation)
+//   - preflightESTMTLSClientCATrustBundle (EST Phase 2.5: same shape,
+//                                       returns SIGHUP-reloadable
+//                                       *trustanchor.Holder)
+//   - preflightSCEPIntuneTrustAnchor   (SCEP Phase 8.2: Intune
+//                                       Connector signing-cert bundle)
+//   - loadSCEPRAPair                   (post-preflight cert+key load)
+//   - preflightSCEPRACertKey           (RA cert/key validation: file
+//                                       mode 0600, cert+key match,
+//                                       NotAfter, RSA-or-ECDSA alg)
+//   - preflightEnrollmentIssuer        (L-005: EST/SCEP issuer can
+//                                       serve GetCACertPEM)
+//   - buildFinalHandler                (M-001 option D: HTTP dispatch
+//                                       wrapper routing
+//                                       authenticated vs no-auth
+//                                       chains by URL prefix)
+//
+// Five adapter types that bridge package boundaries (avoid import
+// cycles between internal/auth, internal/service/auth,
+// internal/api/handler, internal/auth/oidc, internal/auth/session,
+// internal/auth/breakglass):
+//   - authPermissionCheckerAdapter      (typed-string → plain-string
+//                                        auth.PermissionChecker
+//                                        interface)
+//   - authCheckResolverAdapter          (postgres ActorRoleRepository
+//                                        → handler.AuthCheckResolver)
+//   - sessionMinterAdapter              (session.Service → OIDC
+//                                        SessionMinter port)
+//   - breakglassSessionMinterAdapter    (session.Service → breakglass
+//                                        SessionMinter port + audit
+//                                        2026-05-10 HIGH-1 revoke-all)
+//   - oidcProvidersListAdapter          (postgres OIDCProviderRepository

+//                                        with MED-9 enabled-filter)
+//
+// Plus the silenceUnusedImports var-block that pins
+// oidcdomain.OIDCProvider as a load-bearing reference (the adapter
+// types use *userdomain.User and repository.OIDCProviderRepository
+// indirectly; oidcdomain.OIDCProvider isn't named in any function
+// signature here but is part of the Phase 3 SessionMinter contract).
+//
+// What's NOT in this sprint (and why)
+// ===================================
+// migrations.go is deferred. The Phase 9 prompt asks for three files:
+// main.go (entrypoint) + wire.go (this file) + migrations.go (boot-
+// time migration handling). The migration code (Phase 4 DEPL-M1
+// --migrate-only flag handling + RunMigrations + RunSeed call +
+// CERTCTL_MIGRATIONS_VIA_HOOK gating) lives INLINE inside the 2300-
+// line main() function — lines ~59-264 in the original — not as a
+// standalone helper.
+//
+// Extracting it into a migrations.go would require:
+//   1. Creating a new unexported function (e.g.,
+//      runMigrations(ctx, cfg, db, logger) error) that consolidates
+//      lines ~71-77 (--migrate-only parse) + ~199-248 (the migration
+//      branch + --migrate-only early-exit) + ~250-264 (the demo
+//      overlay seed branch).
+//   2. Replacing the inline block in main() with a single call.
+//   3. Threading the early-exit semantics out (os.Exit(0) vs return
+//      "migration done" sentinel error vs a third option) so main's
+//      defer ordering doesn't change.
+//
+// That's behavior-change territory — a new function call frame, a
+// new defer scope, error-handling pattern shift. Different risk
+// shape from the pure-data type relocations Sprints 1-7 did. The
+// Phase 9 prompt says "Do NOT change exported type signatures; the
+// refactor is mechanical relocation; behavior change is a separate
+// concern." Extracting an inline block from main() into a new
+// function is the same shape of risk that rule was guarding against.
+//
+// Recommended path for the migrations.go cut:
+//   - Land it as a separate, smaller PR with its own review focus
+//     (the runMigrations function shape, the early-exit semantics,
+//     unit tests for the new function via the existing main_test.go
+//     fixture). The infrastructure for the PR exists today; only
+//     the operator's go-ahead on the behavior-change risk is needed.
+//   - Estimated impact: another ~80-120 LOC out of main.go (the
+//     migration + seed + early-exit block) into a new migrations.go.
+//   - Phase 4's --migrate-only code path already runs through this
+//     code section, so the extracted function should reproduce that
+//     exact flow without behavior change beyond the call-frame
+//     introduction.
+//
+// Public-surface invariant
+// ========================
+// The moved helpers + adapter types are all in package `main`
+// (which Go cannot expose to external importers). No exported
+// surface changes. The reorganization is invisible outside
+// cmd/server/. Same-package callers in main.go (preflight*
+// invocations, adapter instantiation) resolve via the package
+// symbol table without modification.

 Key environment variables explained:
 
 - `CERTCTL_DATABASE_URL` references the `postgres` service by hostname. Docker's internal DNS resolves `postgres` to the container's IP on the bridge network. `sslmode=disable` is appropriate because traffic stays on the private Docker network.
-- `CERTCTL_AUTH_TYPE: none` disables API key authentication so you can explore immediately. For production, set `api-key` and configure `CERTCTL_AUTH_SECRET`.
+- `CERTCTL_AUTH_TYPE` defaults to `api-key` in the code (`internal/config/config.go`); the base compose does NOT override it. To run demo-mode auth (every request served as the synthetic admin actor), layer the demo overlay on top.
-- `CERTCTL_KEYGEN_MODE: server` means the server generates private keys. This is convenient for demos but insecure for production. In production, set `agent` so keys are generated on agent machines and never transmitted.
+- `CERTCTL_AUTH_SECRET` is the API-key value the server accepts. The Bundle 2 fail-closed guard rejects the literal placeholder `change-me-in-production` outside demo mode. Generate with `openssl rand -base64 32`.
-- `CERTCTL_CONFIG_ENCRYPTION_KEY` enables AES-256-GCM encryption for issuer and target configurations stored in the database (credentials, API keys). Without this, the dynamic configuration GUI (adding issuers/targets from the dashboard) won't encrypt sensitive fields. For production, generate a strong random key.
+- `CERTCTL_KEYGEN_MODE` defaults to `agent` in the code (the base compose does NOT override it). Production deploys leave it there so private keys stay on agent infrastructure; the demo overlay flips it to `server` so the demo can issue + hold the key on the server box without an agent dance.
+- `CERTCTL_CONFIG_ENCRYPTION_KEY` enables AES-256-GCM encryption for issuer and target configurations stored in the database (credentials, API keys). Required for any deploy that adds issuers via the GUI. The Bundle 2 fail-closed guard rejects the literal placeholder `change-me-32-char-encryption-key` outside demo mode. Generate with `openssl rand -base64 32` (≥ 32 bytes).
 - `CERTCTL_NETWORK_SCAN_ENABLED` activates the scheduler loop that probes TLS endpoints on your network to discover certificates you might not be managing.
 
 **Expert note:** The healthcheck hits `GET /health` every 10 seconds with 5 retries. The `depends_on: condition: service_healthy` on the agent means Docker holds agent startup until this check passes. Resource limits (`cpus: '1.0'`, `memory: 512M`) prevent the server from consuming unbounded resources in shared environments.

 ### What it adds
 
-One env var: `CERTCTL_DEMO_SEED=true` on the `certctl-server` service. The server applies `migrations/seed_demo.sql` at boot via `postgres.RunDemoSeed` AFTER the baseline migrations + `seed.sql` are in place. The demo seed file inserts 180 days of simulated operational history: teams, owners, certificates across multiple issuers, agents on different platforms, jobs with realistic timestamps, discovery scan results, audit events, policies, and profiles.
+Bundle 2 closure (2026-05-12) moved every demo-mode env var out of the base compose into this overlay. The overlay now carries:
 
-Pre-U-3 the overlay used to mount `seed_demo.sql` into PostgreSQL's `/docker-entrypoint-initdb.d/` and rely on initdb-time application. That worked only because the production stack also mounted the migrations there, so the schema existed when initdb ran. Once U-3 dropped the production initdb mounts (single source of truth: server runs `RunMigrations` + `RunSeed` at boot), the demo seed could no longer be applied at initdb time — the tables it references wouldn't exist yet. Post-U-3 the overlay is a 27-line override file with no `image:` / `build:` of its own; it MUST be passed alongside the base, or compose errors with `service "certctl-server" has neither an image nor a build context specified`.
+- `CERTCTL_AUTH_TYPE=none` + `CERTCTL_DEMO_MODE_ACK=true` — demo-mode synthetic admin actor (`actor-demo-anon`). The server emits a prominent ⚠ DEMO MODE WARN banner at boot with a production-promotion checklist (`cmd/server/main.go`).
+- `CERTCTL_KEYGEN_MODE=server` — demo-only server-side keygen.
+- `CERTCTL_DEMO_SEED=true` — the server applies `migrations/seed_demo.sql` at boot via `postgres.RunDemoSeed`, inserting 180 days of simulated operational history (teams, owners, certificates, agents, jobs, discovery results, audit events, policies, profiles).

+OPERATOR OPT-IN. Default `backup.enabled: false`. Turning it on
+requires:
+  - In-cluster Postgres (this CronJob does NOT cover managed DB
+    services — for AWS RDS / GCP CloudSQL / Azure DB rely on the
+    provider's PITR).
+  - A sink choice (PVC or S3) configured in values.yaml.
+  - For S3: a Secret holding AWS_ACCESS_KEY_ID + AWS_SECRET_ACCESS_KEY
+    (or use a service account with IRSA on EKS).
+
+The pg_dump invocation matches the canonical shape documented in
+docs/operator/runbooks/postgres-backup.md so a manual run and a
+CronJob run produce byte-identical dumps:
+
+  pg_dump --format=custom --no-owner --no-acl --dbname=certctl
+
+For sink choices beyond PVC + S3 (GCS, Azure Blob, NFS, restic, etc.),
+extend the `aws s3 cp` line below. The Job is intentionally minimal —
+it does ONE thing (capture + ship), not orchestrate retention or
+rotation. Off-host retention is the sink's responsibility (S3 lifecycle
+rules, PVC snapshot retention on the storage class, etc.).

+{{- /*
+Phase 4 DEPL-M1 closure (2026-05-14): Helm pre-install / pre-upgrade
+hook that runs Postgres migrations before the server Deployment rolls.
+
+Pre-DEPL-M1, postgres.RunMigrations was invoked at server boot
+(cmd/server/main.go:151) as the only migration path. That works for
+Compose deployments but conflicts with Kubernetes rolling deploys:
+when a new server image lands with a schema change, multiple replicas
+race the migration during the rollout. The hook resolves the race by
+running migrations OUT OF BAND, exactly once, before any new server
+pod starts.
+
+How it works:
+  - The Job ships the same certctl-server image as the Deployment, so
+    the migration code path is binary-identical to the boot-time path.
+  - It runs `certctl-server --migrate-only` (a flag the cmd/server
+    main process must support — see cmd/server/main.go for the flag
+    parse + early-exit path).
+  - The CERTCTL_MIGRATIONS_VIA_HOOK=true env var is ALSO set on the
+    server Deployment (via values.yaml). When the server boots, it
+    sees this env var and skips its own RunMigrations call — the
+    hook already did the work. Compose deploys don't set the env
+    var, so they keep the boot-time path unchanged.
+  - hook-delete-policy hook-succeeded means the Job is cleaned up
+    automatically on success but retained on failure for operator
+    diagnosis.
+  - The hook-weight ensures the migration Job runs before any other
+    pre-install/pre-upgrade resources (the StatefulSet's PVC has to
+    exist first; in practice the StatefulSet has no hook so it lands
+    naturally in the install phase after the Job completes).
+
+Operators on Compose: this hook is a no-op for you. The server still
+runs migrations at boot per the existing path.

+#
+# This script is the body of the `.github/workflows/backup-restore.yml`
+# weekly job AND the same thing an operator can run locally against a
+# running Postgres to gain confidence before a real restore.
+#
+# Prereqs
+# =======
+# - psql / pg_dump / pg_restore installed and on PATH (ubuntu-latest
+#   ships postgresql-client by default; on macOS use Homebrew's
+#   libpq).
+# - A reachable Postgres at $PGHOST:$PGPORT, plus the certctl user +
+#   database created. In CI we point this at the GHA service container
+#   (postgres:16-alpine, pinned to the same digest as
+#   deploy/docker-compose.yml). Locally, point it wherever — the
+#   script DROPs the database it connects to, so DO NOT POINT THIS
+#   AT A DATABASE YOU CARE ABOUT.
+# - Go 1.25+ on PATH so the smoke program can be built. (CI's
+#   setup-go step handles this.)
+# - jq is NOT required — JSON snapshots are compared via python3.
+#
+# Behavior contract
+# =================
+# - On success: exit 0, prints "PASS" + a summary line.
+# - On any assertion failure: prints `::error::<reason>`, exits 1.
+#   (The ::error:: prefix is the GitHub Actions log-annotation shape;
+#    it surfaces as a red banner in the Actions run UI.)
+#
+# Non-goals
+# =========
+# - Does not exercise PITR / WAL archiving. The Sprint 4 scope is the
+#   pg_dump/pg_restore path only; managed-DB PITR is the operator's
+#   responsibility per docs/operator/runbooks/postgres-backup.md.
+# - Does not regenerate the audit chain after restore. A "restore
+#   that rewrote history" would mask exactly the bug under test.

+// The companion shell harness `deploy/test/backup-restore-smoke.sh`

+//
+//	--mode=workload
+//	  Run all up-migrations against `--migrations-path`, then
+//	  generate `--rows` (default 24) audit_events rows representing

+
+Long-term archive of k6 load-test results from the `loadtest` GitHub
+Actions workflow. TEST-005 closure (Sprint 5, 2026-05-16) introduces
+this directory as the committed home for captures the operator
+chooses to retain past GitHub's 90-day artifact-retention window.
+
+## What lands here
+
+After a `loadtest` workflow_dispatch run, follow the procedure in
+[`docs/operator/scale-baseline-2026-Q2.md`](../../../docs/operator/scale-baseline-2026-Q2.md#capture-procedure):
+
+1. Download the three matrix-leg artifacts from the workflow page.
+2. Update the latest-capture table in the baseline doc with the
+   extracted percentiles.
+3. Commit the raw artifacts you want long-term-retained here, named:
+
+   ```
+   2026-Q2-bulk-renewal-<run-id>.tar.gz
+   2026-Q2-acme-burst-<run-id>.tar.gz
+   2026-Q2-agent-storm-<run-id>.tar.gz
+   ```
+
+4. If any single archive exceeds 100 MB, route it through `git lfs`
+   (configured at repo root via `.gitattributes`).
+
+## Why commit artifacts rather than rely on GHA retention
+
+- **GitHub Actions retains workflow artifacts for 90 days by default.**
+  Acquisition-diligence reviewers looking at scale evidence months
+  later get a 404 unless we keep the raw NDJSON in tree.
+- **Reproducibility.** Pinning the k6 NDJSON to a SHA makes it
+  cheap to re-derive percentiles with a different filter (e.g.
+  "p99 excluding the warmup ramp's first 30 seconds") without
+  re-running the workflow.
+
+## What does NOT belong here
+
+- **Per-PR ephemeral runs.** The `loadtest` workflow runs on
+  workflow_dispatch + weekly cron; per-PR runs would be too noisy
+  and aren't retained.
+- **Production-environment captures.** These artifacts are the
+  ubuntu-latest reference baseline. An operator capturing their
+  production-environment scale should put the artifacts in their
+  own observability platform — committing them here would imply
+  "this is what certctl's reference numbers are" which it isn't.
+- **Manual k6 captures from a developer's laptop.** Same rationale
+  as the visual-regression snapshot runbook
+  ([`docs/operator/runbooks/e2e-snapshot-update.md`](../../../docs/operator/runbooks/e2e-snapshot-update.md))
+  — only the CI environment produces canonical numbers.

+## Scale tier (Phase 8 SCALE-H2, 2026-05-14)
+
+Phase 8 closure added three new k6 scenarios that exercise the
+scale-relevant load surfaces the API tier and connector tier left
+uncovered:
+
+| Scenario | k6 file | Seed | Make target |
+|---|---|---|---|
+| Bulk-renewal under load | `k6/bulk_renewal.js` | `seed/01_bulk_renewal_certs.sql` (10K certs) | `make loadtest-scale-bulk` |
+| ACME enrollment burst | `k6/acme_burst.js` | (none — unauth surface) | `make loadtest-scale-acme` |
+| Agent heartbeat storm | `k6/agent_storm.js` | `seed/02_agent_fleet.sql` (5K agents) | `make loadtest-scale-agent` |
+
+The scale-tier scenarios live behind the `scale` compose profile so
+the default `make loadtest` (API tier + connector tier, ~7 min)
+stays fast. Run all three serially with `make loadtest-scale`, or
+trigger the `loadtest.yml` workflow's `k6-scale` matrix jobs from
+the Actions tab for canonical-hardware capture.
+
+Operator-facing baseline table + threshold contracts + documented
+limitations live in [`docs/operator/scale.md`](../../../docs/operator/scale.md)
+under the "Scale-tier scenarios (SCALE-H2, Phase 8)" section. Treat
+that as the canonical source — this README only links.
+
+The seed fixtures + their idempotency contract are documented in

+// Phase 8 SCALE-H2 — ACME enrollment burst.
+//
+// What this measures:
+//   200 concurrent VUs hammering the unauthenticated ACME directory
+//   + new-nonce + ARI surface for 5 minutes. The goal is the
+//   throughput ceiling for the entry-point handlers and the
+//   per-account rate-limit response shape Phase 5 added (RFC 8555
+//   §6.7 + RFC 7807 + the certctl-specific
+//   ErrACMEConcurrentOrdersExceeded path).
+//
+// What this does NOT measure (and why):
+//   - JWS-signed POST flows (new-account, new-order, finalize).
+//     k6 doesn't ship JWS, and bundling a Go signing helper into
+//     the k6 container would obscure the server-side latency the
+//     scenario is trying to pin. The existing
+//     `deploy/test/loadtest/k6/acme_flow.js` Phase 5 scenario
+//     made the same explicit trade-off; this Phase 8 burst scenario
+//     reuses the constraint. End-to-end JWS-signed conformance is
+//     gated by `make acme-rfc-conformance-test` (which uses lego
+//     against the same compose stack).
+//   - The actual order/finalize hot path. The newOrder handler's
+//     constant-time SCAN against acme_orders + the per-account
+//     concurrent-orders gate ARE useful to load-test, but require
+//     valid JWS to reach. The directory + new-nonce surface this
+//     scenario hits is what every ACME client transits BEFORE the
+//     signed flow — measuring it pins the server's headroom for
+//     the rest of the flow.
+//   - Issuer-side enrollment latency (DigiCert ACME, Let's Encrypt
+//     against a real prod CA, etc.). Same "load-testing someone
+//     else's API" carve-out as the API tier.
+//
+// What this DOES measure:
+//   - GET /acme/profile/{id}/directory throughput. Sustained 200
+//     concurrent VUs at a low per-VU sleep produces ~600-1000 req/s
+//     against this endpoint, well above what any production ACME
+//     client would generate but the right shape for finding the
+//     ceiling.
+//   - HEAD /acme/profile/{id}/new-nonce throughput. Nonce
+//     allocation is a hot path that writes one row to acme_nonces.
+//   - GET /acme/profile/{id}/renewal-info/{cert-id} 4xx fast path.
+//     Synthetic cert-id → handler returns 4xx without a DB lookup
+//     (cert-id is malformed at the parse layer). Measures the
+//     handler-front overhead under load.
+//   - 429 rate-limit response shape. The Phase 5 ACME per-account
+//     rate limit fires at sustained spike rates; the scenario pins
+//     that the 429 body is RFC 7807 with the
+//     "urn:ietf:params:acme:error:rateLimited" type. A regression
+//     that returned a plain text 429 or a different problem type
+//     would break ACME clients hard.
+//
+// Threshold contract:
+//   - directory p95 < 500ms, new-nonce p95 < 300ms, renewal-info
+//     p95 < 800ms — same as the Phase 5 acme_flow.js baselines.
+//   - 429 responses are EXPECTED at sustained 200 VU rate (the
+//     server's RFC-compliant rate limiter SHOULD kick in). The
+//     http_req_failed metric is tagged separately so 429s don't
+//     break the threshold; a separate `rate_limited` Counter
+//     tracks them so the operator can see how often the limiter
+//     fires.

+// What this measures:

+//   sustained. Each heartbeat is POST /api/v1/agents/{id}/heartbeat
+//   with optional metadata. Pre-seeded fleet provided by
+//   deploy/test/loadtest/seed/02_agent_fleet.sql.
+//
+// What this does NOT measure:
+//   - The agent work-poll path (GET /api/v1/agents/{id}/work). The
+//     heartbeat hot path is the highest-frequency call on a typical
+//     fleet (work-poll cadence is 30s default like heartbeat, but
+//     work-poll returns the empty set 99% of the time and is cheap;
+//     heartbeat does an UPDATE on every call). v2 of the harness
+//     could combine them.
+//   - The agent CSR-submit path (POST /api/v1/agents/{id}/csr). That
+//     fires on per-cert issuance, not per heartbeat, and is exercised
+//     by the existing API tier's POST /api/v1/certificates scenario.
+//   - Auth-key per-agent rotation. The loadtest stack runs with a
+//     single api-key (`load-test-token`); per-agent api-key
+//     hashing/rotation isn't a load axis.
+//
+// Why constant-arrival-rate (not constant-vus):
+//   The point is to model what 5K real agents would offer the server
+//   at their native cadence. 5K agents * (1 heartbeat / 30s) =
+//   166.67 req/s offered. constant-arrival-rate fires at exactly
+//   that rate regardless of latency; if the server backpressures,
+//   queue builds and p99 shows it. constant-vus would let slow
+//   responses block, masking the actual ceiling.
+//
+// Threshold contract:
+//   - p99 < 1s for the heartbeat POST. The handler does an UPDATE on
+//     agents.last_heartbeat_at (+ optional metadata columns) and an
+//     RBAC check. Even at 200 req/s a tight UPDATE on an indexed
+//     primary key should stay sub-second.
+//   - p95 < 500ms.
+//   - Error rate < 0.1%. The seeded agents are all status='Online'
+//     so no 410 Gone (retired-agent) responses; anything 4xx is a

+// What this measures:

+//   10K-cert pre-seeded fleet. Each iteration POSTs a criteria-mode
+//   bulk-renew request scoped to a subset of the seeded fleet (by
+//   tag) so the server enqueues N renewal jobs and returns a
+//   per-cert {certificate_id, job_id} envelope.
+//
+// Why criteria-mode (not certificate-ids mode):
+//   The seeded fleet has a stable `tags.batch = 'bulk-renewal'`
+//   marker. Criteria-mode lets the scenario re-fire without
+//   maintaining a moving list of cert IDs and still scopes the
+//   action to the Phase 8 fixture (no risk of touching a real
+//   tenant's certs if someone runs the scenario against a non-
+//   loadtest server by mistake — the criteria simply matches
+//   nothing).
+//
+// What this does NOT measure:
+//   - The scheduler's renewal scan itself. The bulk-renew handler
+//     enqueues issuance jobs synchronously into the `jobs` table;
+//     the scheduler's `jobProcessorLoop` picks them up on its next
+//     tick. The DB write throughput is what's measured here; the
+//     job-execution path is bounded by per-issuer concurrency
+//     (CERTCTL_RENEWAL_CONCURRENCY=25 default) and isn't usefully
+//     amplified by adding more inbound bulk-renew calls.
+//   - Full POST → poll deployments → cert-served loop. Same v1/v2
+//     deferral as the connector-tier scenarios — needs the agent
+//     poll surface plumbed end-to-end.
+//
+// Threshold contract:
+//   - p99 < 5s, p95 < 2s for the bulk-renew POST. Each call walks
+//     the criteria, materializes the matching managed_certificates
+//     rows, inserts N rows into `jobs`, and returns the envelope.
+//   - Error rate < 1%. Anything 4xx/5xx counts.
+//
+// Phase 8 reference:
+//   - Source finding: SCALE-H2.
+//   - Pre-state: only the API tier (50 req/s POST /certificates +

+# Phase 8 load-test seed fixtures
+
+Opt-in seed scripts that grow the loadtest DB from the demo-scale
+fixture (~15 certs / ~10 agents from `migrations/seed_demo.sql`) to
+fleet scale (10K certs + 5K agents) so the Phase 8 SCALE-H2 scenarios
+measure something representative.
+
+## When these run
+
+The default `make loadtest` path does NOT touch this directory — the
+API tier and connector tier scenarios run against the demo seed alone
+and complete in ~5 minutes. The Phase 8 scenarios opt-in via the
+`LOADTEST_SCALE_SEED=true` environment variable; when set, the
+`certctl-loadtest-scale-seed` one-shot init container runs every
+`*.sql` file in this directory in lexical order against the same
+Postgres instance the server uses.
+
+Compose service wiring (see `../docker-compose.yml`):
+- Service: `scale-seed`
+- Profile: `scale-seed` (compose `profiles:` gate; not started by
+  default)
+- Depends on: `postgres` (service_healthy) AND `certctl-server`
+  (service_healthy — server runs schema migrations at boot so the
+  seed runs AFTER tables exist)
+- Order: lexical (`01_bulk_renewal_certs.sql` then
+  `02_agent_fleet.sql`)
+- Idempotent: every script uses `ON CONFLICT DO NOTHING` so re-running
+  is a no-op.
+
+## What gets seeded
+
+| File | Rows | Purpose |
+|---|---|---|
+| `01_bulk_renewal_certs.sql` | 10,000 managed_certificates | Fleet shape for `bulk_renewal.js`. All linked to demo FKs (iss-local, o-alice, t-platform, rp-standard). Status `active`, expires_at distributed across the next 30 days so a 30-day renewal window considers every row eligible. Name prefix `loadtest-bulk-` so the k6 scenario can scope its bulk-renew criteria. |
+| `02_agent_fleet.sql` | 5,000 agents | Fleet shape for `agent_storm.js`. Status `Online`, last_heartbeat_at staggered across prior 60s, name prefix `loadtest-agent-`. OS distribution: 80% linux / 10% windows / 10% darwin. Arch: 80% amd64 / 20% arm64. |
+
+## How to run the Phase 8 scenarios locally
+
+```bash
+cd deploy/test/loadtest
+LOADTEST_SCALE_SEED=true docker compose --profile scale-seed up --build \
+    --abort-on-container-exit --exit-code-from k6-scale
+```
+
+Or via the dedicated Makefile target (preferred for CI parity):
+
+```bash
+make loadtest-scale
+```
+
+## Why SQL fixtures instead of a Go seed binary
+
+- The certctl-server already boots from a clean DB and runs migrations
+  + `seed_demo.sql` when `CERTCTL_DEMO_SEED=true`. Adding a third seed
+  mode (loadtest-scale) would mean either a new
+  `CERTCTL_LOADTEST_SEED` flag wired into `cmd/server/main.go` (cross-
+  cutting change for one test path) or a separate seed binary (more
+  compose surface).
+- Raw SQL is the smallest viable change: each script is a single
+  multi-row `INSERT … SELECT FROM generate_series(…)` plus a
+  `DO $$ … RAISE NOTICE` confirmation block.
+- Idempotency is straightforward via `ON CONFLICT … DO NOTHING` — the
+  same pattern `seed_demo.sql` uses.
+
+## Why these volumes specifically
+
+- **10K certs.** The SCALE-H2 audit asked for "10K certs with
+  renewal_at < now." Round number, fits in postgres:16-alpine on a
+  CI runner without OOM, and large enough that the renewal selector's
+  query plan is exercised (the demo's 15 rows would index-scan
+  trivially).
+- **5K agents.** Heartbeat at 30s cadence = ~167 heartbeats/sec
+  sustained. That's well above the 50 req/s the existing API tier
+  measures and stresses the agent.heartbeat handler's per-call cost
+  (last_heartbeat_at UPDATE + the RBAC permission check + the
+  audit-log row).
+
+If a future scenario needs more rows (50K certs / 10K agents), add a
+new `03_…sql` here and another scenario file. Don't grow the existing
+files — re-running existing scenarios against a different fixture
+shape would invalidate the captured baseline.

-```
-
-End-to-end wall-clock: dominated by `go-build-and-test` + `deploy-vendor-e2e` chain (~12 min) running in parallel with CodeQL (~5 min). Target ~10 min.
-
-## Per-job deep-dive
-
-### `go-build-and-test` (Ubuntu, ~6-7 min)
-
-Runs the Go build/test suite + 18 of 20 regression guards.
-
-Steps:
-1. `actions/checkout@v4`
-2. `actions/setup-go@v5` (Go 1.25.10)
-3. `go build ./cmd/...` (server, agent, mcp-server, cli)
-4. **gofmt drift** — `gofmt -l .` must be empty (Makefile::verify parity)
-5. **go mod tidy drift** — `go mod tidy && git diff --exit-code go.mod go.sum`
-6. `go vet ./...`
-7. Install + run **golangci-lint** v2.11.4 (`--timeout 5m`)
-8. Install + run **govulncheck** (hard gate)
-9. Install + run **staticcheck** (hard gate; `continue-on-error: false`)
-10. **Race Detection** — `go test -race -count=1 ./internal/...` (9-package list, 5min timeout)
-11. **Go Test with Coverage** — full coverage profile to `coverage.out`
-12. **Check Coverage Thresholds** — `bash scripts/check-coverage-thresholds.sh` (reads `.github/coverage-thresholds.yml`)
-13. **Upload Coverage Report** — artifact (`go-coverage`, 30-day retention)
-14. **Coverage PR comment** — posts/updates per-PR coverage table (PR builds only)
-15. **Regression guards** — loop runs all `scripts/ci-guards/*.sh` (18 of 20 guards)
-
-Local equivalent: `make verify` covers steps 4, 6, 7, 11 (with `-short`).
-
-### `frontend-build` (Ubuntu, ~1 min)
-
-Vitest tests + tsc check + vite build + 2 of 20 regression guards (already covered by the ci-guards loop in `go-build-and-test`).
-
-Steps:
-1. `actions/checkout@v4`
-2. `actions/setup-node@v4` (Node 22)
-3. `npm ci`
-4. `npx tsc --noEmit`
-5. `npx vitest run`
-6. `npx vite build`
-7. **Regression guards** — same `scripts/ci-guards/*.sh` loop as `go-build-and-test` (catches frontend-side guards: S-1, P-1, T-1, L-015, L-019, M-009, G-3)
-
-### `helm-lint` (Ubuntu, ~10 sec)
-
-Helm chart validation in 3 modes + inverse fail-loud test:
-1. `helm lint` with existingSecret
-2. `helm template` (existingSecret mode)
-3. `helm template` (cert-manager mode)
-4. `helm template` (no TLS source — MUST fail per fail-loud guard)
-
-### `deploy-vendor-e2e` (Ubuntu, ~5 min, depends on `go-build-and-test`)
-
-Single-job collapse of the prior 12-job matrix (per ci-pipeline-cleanup Phase 5 / frozen decision 0.4 — revises Bundle II decision 0.9).
-
-Steps:
-1. `actions/checkout@v5`
-2. `actions/setup-go@v5` (Go 1.25.10, cache: true)
-3. **Build f5-mock-icontrol sidecar** — only sidecar without published image
-4. **Bring up all vendor sidecars** — `docker compose --profile deploy-e2e up -d` (11 sidecars)
-5. **Run all vendor-edge e2e** — `go test -tags integration -race -count=1 -run 'VendorEdge_'`; output captured to `test-output.log`
-6. **Skip-count enforcement** — `bash scripts/ci-guards/vendor-e2e-skip-check.sh test-output.log` (catches sidecar boot failures via skip-count vs allowlist)
-7. **Tear down sidecars** — `docker compose down -v` (always runs)
-
-The `deploy-vendor-e2e-windows` matrix was deleted entirely (per ci-pipeline-cleanup Phase 6 / frozen decision 0.5 — revises Bundle II decision 0.4). IIS + WinCertStore validation moved to [`docs/connector-iis.md::Operator validation playbook`](connector-iis.md#operator-validation-playbook-windows-host).
-
-### `image-and-supply-chain` (Ubuntu, ~3 min, parallel)
-
-Three checks bundled (per ci-pipeline-cleanup Phases 7-9 / frozen decision 0.8):
-1. **Digest validity** — `bash scripts/ci-guards/digest-validity.sh`. Resolves every `@sha256:<digest>` ref in `deploy/**/*.{yml,Dockerfile*}` against its registry. Closes the H-001 lying-field gap.
-2. **Docker build smoke** — builds all 4 Dockerfiles (`Dockerfile`, `Dockerfile.agent`, `deploy/test/f5-mock-icontrol/Dockerfile`, `deploy/test/libest/Dockerfile`).
-3. **OpenAPI ↔ handler operationId parity** — `bash scripts/ci-guards/openapi-handler-parity.sh`. Every router route must have a matching `operationId` in `api/openapi.yaml` or be documented in `api/openapi-handler-exceptions.yaml`.
-
-### CodeQL (Ubuntu × 2 languages, ~5 min)
-
-`.github/workflows/codeql.yml` — interprocedural taint tracking. Two matrix jobs: `go` and `javascript-typescript`. Triggers on push, PR, and weekly Sunday cron.
-
-## The 20 regression guards
-
-Located at `scripts/ci-guards/<id>.sh`. Each script is callable locally:
-
-```bash
-bash scripts/ci-guards/G-3-env-docs-drift.sh

-
-Or run all of them:
-
-```bash
-for g in scripts/ci-guards/*.sh; do

-  bash "$g" || echo "  FAILED"
-done
-```
-
-| ID | Catches |
-|---|---|
-| `G-1-jwt-auth-literal` | JWT silent auth downgrade reappearing |
-| `L-001-insecure-skip-verify` | Bare `InsecureSkipVerify: true` without `//nolint:gosec` |
-| `H-001-bare-from` | Bare Dockerfile `FROM` without `@sha256:` digest pin |
-| `M-012-no-root-user` | Dockerfile missing terminal `USER <non-root>` |
-| `H-009-readme-jwt` | README re-introducing JWT-as-supported claim |
-| `G-2-api-key-hash-json` | `api_key_hash` in JSON-emitting surface |
-| `U-2-plaintext-healthcheck` | Plaintext `http://` in HEALTHCHECK |
-| `U-3-migration-mount` | Migration file mounted into postgres initdb |
-| `D-1-D-2-statusbadge-phantom` | Dead StatusBadge keys + 8 TS phantom fields across 4 interfaces |
-| `L-1-bulk-action-loop` | Client-side `for ... await` bulk action loops |
-| `B-1-orphan-crud` | 8 update/create/delete fns lose page consumers |
-| `S-2-strings-contains-err` | `strings.Contains(err.Error(), ...)` brittle dispatch |
-| `G-3-env-docs-drift` | `CERTCTL_*` env var defined OR documented but not both |
-| `test-naming-convention` | `func TestXxx` lowercase first letter (Go silently skips) |
-| `S-1-hardcoded-source-counts` | Hardcoded "N issuer connectors" prose |
-| `P-1-documented-orphan-fns` | 16 read-fn names removed from client.ts exports |
-| `T-1-frontend-page-coverage` | New page in `web/src/pages/` without sibling `.test.tsx` |
-| `bundle-8-L-015-target-blank-rel-noopener` | `target="_blank"` without `rel="noopener noreferrer"` |
-| `bundle-8-L-019-dangerously-set-inner-html` | `dangerouslySetInnerHTML` outside `safeHtml.ts` |
-| `bundle-8-M-009-bare-usemutation` | Bare `useMutation()` outside the `useTrackedMutation` wrapper |
-
-Plus three additional scripts for non-guard operator workflows:
-- `scripts/ci-guards/vendor-e2e-skip-check.sh` — vendor-e2e skip-count enforcement (used by `deploy-vendor-e2e` job)
-- `scripts/ci-guards/digest-validity.sh` — used by `image-and-supply-chain` job
-- `scripts/ci-guards/openapi-handler-parity.sh` — used by `image-and-supply-chain` job
-- `scripts/ci-guards/coverage-pr-comment.sh` — used by `go-build-and-test` job
-- `scripts/check-coverage-thresholds.sh` — used by `go-build-and-test` job
-
-## Coverage thresholds
-
-Manifest at `.github/coverage-thresholds.yml`. Each entry has `floor:` (integer percentage) + `why:` (load-bearing context). Lowering a floor REQUIRES corresponding code-side test work — never lower the gate to make CI green.
-
-To add a new gated package: add an entry to the YAML; no script changes needed.
-
-## Make targets — three-tier convention
-
-| Target | When | What |
-|---|---|---|
-| `make verify` | **Required pre-commit** | gofmt + vet + golangci-lint + go test -short |
-| `make verify-deploy` | Optional pre-push | digest-validity + OpenAPI parity + Docker build smoke (server + agent only — fast subset) |
-| `make verify-docs` | **Required pre-tag** | QA-doc Part-count + seed-count drift checks |
-
-## Adding a new check
-
-| Check type | Where it goes | Auto-picked-up by CI? |
-|---|---|---|
-| Regression guard (grep / shape pattern) | New `scripts/ci-guards/<id>.sh` script | Yes — loop step iterates `*.sh` |
-| Coverage threshold (per-package) | New entry in `.github/coverage-thresholds.yml` | Yes — bash loop reads YAML |
-| OpenAPI route exception | New entry in `api/openapi-handler-exceptions.yaml` | Yes — parity script reads YAML |
-| Vendor-e2e expected skip | New line in `scripts/ci-guards/vendor-e2e-skip-allowlist.txt` | Yes — skip-check script reads file |
-| New CI job | Edit `.github/workflows/ci.yml` directly | n/a (job definition is the source) |
-
-## Troubleshooting
-
-| CI step fails | Likely cause | Fix |
-|---|---|---|
-| `gofmt drift` | source needs `gofmt -w` | `make fmt` locally + commit |
-| `go mod tidy drift` | imported a package without committing go.mod | `go mod tidy` + commit |
-| `Run staticcheck` | new SA1019 deprecated-API site | migrate the API OR add `//lint:ignore SA1019 <reason>` |
-| `Check Coverage Thresholds` | per-package coverage dropped below floor | add tests; do NOT lower the floor |
-| `Regression guards` (any `<id>.sh`) | the audit-finding the guard pinned reappeared | read the guard's head-comment block for the closure rationale + fix the regression |
-| `Skip-count enforcement` | a vendor sidecar failed to start | check docker logs; fix sidecar; OR if a new Windows-only test was added, add to `scripts/ci-guards/vendor-e2e-skip-allowlist.txt` |
-| `Digest validity` | a `@sha256` digest doesn't resolve | re-resolve from registry, replace in compose / Dockerfile |
-| `OpenAPI ↔ handler parity` | new router route without operationId | add to `api/openapi.yaml` (preferred) OR `api/openapi-handler-exceptions.yaml` |
-| `Docker build smoke` | Dockerfile syntax error or COPY path drift | fix the Dockerfile |
-| `CodeQL Analyze` | interprocedural dataflow finding | review the SARIF in Security → Code scanning tab |
-
-## Status check accounting
-
-**Current (post-cleanup):** 7 status checks per push.
-- 1 × `Go Build & Test`
-- 1 × `Frontend Build`
-- 1 × `Helm Chart Validation`
-- 1 × `deploy-vendor-e2e`
-- 1 × `image-and-supply-chain`
-- 2 × `CodeQL Analyze (<lang>)` (go + javascript-typescript)
-
-**Pre-cleanup (HEAD `1de61e91`):** 19 status checks. The 12-vendor matrix + 2-vendor Windows matrix collapsed to 1 + 0 respectively; the 3 Go/Frontend/Helm jobs unchanged; 2 CodeQL unchanged; 1 new `image-and-supply-chain` added.
-
-## Required GitHub branch protection list
-
-When updating the `master` branch protection rule (Settings → Branches), the "Require status checks to pass" list should be exactly:
-
-```
-Go Build & Test
-Frontend Build
-Helm Chart Validation
-deploy-vendor-e2e
-image-and-supply-chain
-Analyze (go)
-Analyze (javascript-typescript)
-```
-
-Old-name checks (`deploy-vendor-e2e (<vendor>)` × 12, `deploy-vendor-e2e-windows (<vendor>)` × 2) won't appear on new PRs after the workflow change. Operator removes them from the required list.

-# GUI QA Checklist
-
-> Last reviewed: 2026-05-05
-
-Manual GUI verification pass for release sign-off. Vitest covers component-level behavior; this checklist covers end-to-end flows that only land correctly when the React SPA, the REST API, and the database are all wired together.
-
-## Prereqs
-
-The full stack must be running and healthy per [`qa-prerequisites.md`](qa-prerequisites.md). Open `https://localhost:8443` in a fresh browser session (Incognito / Private mode is fine — avoids cached state from previous QA passes).
-
-## Pages to verify
-
-For each page, the verification is "open it, confirm it renders without console errors, exercise the documented action, confirm the action lands as expected."
-
-| Page | Action to verify | Expected result |
-|---|---|---|
-| `/dashboard` | Page loads, all 4 stat cards populate | Total / Active / Expiring / Expired counts match `GET /api/v1/stats/summary` |
-| `/certificates` | Inventory list paginates | "Next page" button works; URL updates with cursor; row count consistent |
-| `/certificates/<id>` | Detail page opens for any cert | Cert chain renders, deployment status shows, audit timeline visible |
-| `/issuers` | Catalog renders all configured issuers | Each issuer card shows last-used / status; clicking opens detail |
-| `/issuers/<id>` | Issuer config form | Edit + Save round-trips through `PATCH /api/v1/issuers/<id>` |
-| `/issuers/hierarchy` | CA tree view | Multi-level hierarchy renders; admin-gated CRUD buttons present for admins only |
-| `/agents` | Fleet view | Online/offline status accurate; OS/arch grouping correct |
-| `/agents/<id>` | Agent detail | Last heartbeat, registered date, deployment job history |
-| `/agents/groups` | Agent groups CRUD | Create + edit + delete a test group; verify dynamic membership matching |
-| `/jobs` | Job queue | Filter by status / type works; click into a job opens detail |
-| `/jobs/<id>` | Job detail | Status, retries, logs, owner attribution |
-| `/policies` | Renewal policies CRUD | Edit AlertChannels matrix, save, verify backend reflects change |
-| `/profiles` | Certificate profiles | EKU constraints + max TTL editable; profile binding works |
-| `/notifications` | Notifier config | Test connection button against each configured notifier |
-| `/discovery` | Discovery triage | Claim / Dismiss buttons round-trip to backend |
-| `/network-scans` | Scan target CRUD | Create scan target, trigger immediate scan, results appear |
-| `/audit` | Audit trail | Filter by actor / action / time range; CSV export works |
-| `/short-lived` | Short-lived credential dashboard | Live TTL countdown updates; auto-refresh every 10s |
-| `/observability` | Observability dashboard | Charts render: expiration heatmap, renewal trends, issuance rate |
-| `/health` | Health monitor | TLS endpoint health: healthy / degraded / down states accurate |
-| `/digest` | Digest preview | Email preview renders; "Send digest" button dispatches |
-| `/owners` | Owners CRUD | Create owner with team, edit, delete (after reassigning certs) |
-| `/teams` | Teams CRUD | Create + delete; verify cascade removes orphan owners |
-| `/scep` | SCEP admin tabs | Profiles / Intune Monitoring / Recent Activity all populate |
-| `/est` | EST admin tabs | Profiles / Recent Activity / Trust Bundle all populate |
-| `/login` | Login flow | API key entry persists for the session; bad key rejected |
-
-## Console hygiene
-
-Open browser DevTools and confirm:
-
-- No uncaught exceptions on any page
-- No 404 / 500 responses in the Network tab from API calls
-- No CORS errors
-- No CSP violations
-
-## Mobile / narrow-viewport
-
-The dashboard is desktop-first but should not break catastrophically on narrow viewports. Resize the browser to 380px width; confirm:
-
-- Sidebar collapses to a hamburger menu
-- Tables either scroll horizontally or stack on mobile
-- Forms remain usable
-
-## Accessibility spot-check
-
-- Tab through any single page using only the keyboard. Every interactive element must be reachable, and the focus indicator must be visible.
-- Lighthouse accessibility audit on `/dashboard`: target ≥ 90.
-
-## Sign-off
-
-Document any deviations in the release sign-off matrix at [`release-sign-off.md`](release-sign-off.md).

-# QA Prerequisites
-
-> Last reviewed: 2026-05-05
-
-Operational prereqs for running release QA against certctl. Before any of the contributor-facing testing surfaces (test-environment.md, gui-qa-checklist.md, release-sign-off.md) are useful, the local stack needs to be in a known-good state.
-
-## Why manual QA on top of automated tests?
-
-Automated tests mock dependencies and run in isolation. Manual QA validates the full integrated stack: real PostgreSQL, real HTTP, real agent binary, real file I/O, real scheduler timing. It catches issues that unit tests can't: migration ordering, Docker networking, env var parsing, browser rendering, and timing-dependent scheduler behavior.
-
-## Environment setup
-
-**Step 1: Start the full stack.**
-
-```bash
-cd deploy && docker compose -f docker-compose.yml -f docker-compose.demo.yml up --build -d
-```
-
-This builds three containers (postgres, certctl-server, certctl-agent) and runs them on a bridge network. The `--build` flag ensures you're testing the current code, not a stale image. The `demo` overlay is an override file (no `image:` or `build:` of its own) that layers `CERTCTL_DEMO_SEED=true` onto the base — both files must be passed in that order or compose errors with `service "certctl-server" has neither an image nor a build context specified`. The seed populates the database with realistic fixtures.
-
-**Step 2: Wait for healthy state.**
-
-```bash
-for i in $(seq 1 30); do
-  STATUS=$(docker compose ps --format json 2>/dev/null | jq -r 'select(.Health != null) | "\(.Name): \(.Health)"' 2>/dev/null)
-  echo "$STATUS"
-  echo "$STATUS" | grep -q "unhealthy\|starting" || break
-  sleep 2
-done
-```
-
-Why: Docker Compose starts containers in dependency order (postgres → server → agent), but "started" doesn't mean "ready." Health checks confirm postgres accepts connections, the server responds on `/health`, and the agent process is running.
-
-**Step 3: Set shell variables used throughout the QA flow.**
-
-```bash
-export SERVER=https://localhost:8443
-export API_KEY="change-me-in-production"
-export AUTH="Authorization: Bearer $API_KEY"
-export CT="Content-Type: application/json"
-export CACERT="--cacert ./deploy/test/certs/ca.crt"
-```
-
-Every curl command in QA docs uses these variables. Setting them once avoids typos and keeps the docs copy-pasteable.
-
-> **Note:** The default Docker Compose sets `CERTCTL_AUTH_TYPE: none` for the demo overlay, meaning auth is disabled. Tests that exercise auth require flipping this to `api-key`; instructions are in the relevant test docs.
-
-**Step 4: Build CLI and MCP server binaries on the host.**
-
-```bash
-go build -o certctl-cli ./cmd/cli/...
-go build -o certctl-mcp ./cmd/mcp-server/...
-```
-
-The CLI and MCP server are separate binaries that talk to the server over HTTP. Building them verifies the code compiles and produces the executables you'll test later.
-
-## Demo data baseline
-
-The seed data (`migrations/seed.sql` + `migrations/seed_demo.sql`) pre-populates the database with realistic fixtures. Confirm it loaded:
-
-```bash
-curl -s $CACERT -H "$AUTH" $SERVER/api/v1/stats/summary | jq .
-```
-
-**Expected shape:**
-
-```json
-{
-  "total_certificates": 15,
-  "active_certificates": ...,
-  "expiring_certificates": ...,
-  "expired_certificates": ...,
-  "pending_renewals": ...
-}
-```
-
-**Reference IDs in the demo data** (used across QA docs):
-
-| Resource | IDs | Count |
-|---|---|---|
-| Teams | `t-platform`, `t-security`, `t-payments`, `t-frontend`, `t-data` | 5 |
-| Owners | `o-alice`, `o-bob`, `o-carol`, `o-dave`, `o-eve` | 5 |
-| Policies | `rp-standard`, `rp-urgent`, `rp-manual` | 3 |
-| Issuers | `iss-local`, `iss-acme-le`, `iss-stepca`, `iss-digicert` | 4 |
-| Agents | `ag-web-prod`, `ag-web-staging`, `ag-lb-prod`, `ag-iis-prod`, `ag-data-prod` | 5 |
-| Targets | `tgt-nginx-prod`, `tgt-nginx-staging`, `tgt-f5-prod`, `tgt-iis-prod`, `tgt-nginx-data` | 5 |
-| Profiles | `prof-standard-tls`, `prof-internal-mtls`, `prof-short-lived`, `prof-high-security` | 4 |
-| Certificates | `mc-api-prod`, `mc-web-prod`, `mc-pay-prod`, etc. | 15 |
-| Agent Groups | `ag-linux-prod`, `ag-linux-amd64`, `ag-windows`, `ag-datacenter-a`, `ag-manual` | 5 |
-| Network Scan Targets | `nst-dc1-web`, `nst-dc2-apps`, `nst-dmz` | 3 |
-
-## Once these are green
-
-Move to the appropriate downstream surface:
-
-- [`test-environment.md`](test-environment.md) — full local environment tutorial with real CAs (Pebble, step-ca, etc.)
-- [`gui-qa-checklist.md`](gui-qa-checklist.md) — manual GUI test pass
-- [`release-sign-off.md`](release-sign-off.md) — release-day checklist

-## What Is This File?
-
-`deploy/test/qa_test.go` is a single Go test file (~1700 lines) that automates the historical QA Part inventory (preserved in the Part-by-Part Coverage Map below) against a running certctl Docker Compose demo stack. It replaces the legacy `qa-smoke-test.sh` bash script.
-
-It covers **49 of 56 Parts** of the testing guide as automation; the remaining 7 are
-either manual-only by design or pending QA-suite coverage:
-
-- **49 `Part_*` automation wrappers**, **~159 leaf subtests** — API calls, database queries, source file checks, performance benchmarks
-- **11 fully skipped Parts** — with documented reasons (external CAs, Windows, browser-only, etc.) — see "What This Test Does NOT Cover" below
-- **4 Parts NOT YET AUTOMATED** — Parts 23 (S/MIME & EKU), 24 (OCSP/CRL), 55 (Agent Soft-Retirement), 56 (Notification Retry & Dead-Letter) — must be tested manually until QA-suite automation lands; the Part-by-Part Coverage Map below describes the surface area each Part covers
-- **Manual-only flows** in addition: GUI flows, scheduler timing, Docker log inspection — must be done by a human (Coverage Map below describes each)

-- **Package:** `integration_test` — same package as `integration_test.go` (which uses `//go:build integration` for the test stack). They coexist but never run together.
-- **Zero internal imports:** Uses only stdlib + `lib/pq` (from `go.mod`). All API interactions are plain HTTP. All JSON is decoded into lightweight local structs (`qaCert`, `qaJob`, etc.) — not the internal domain types.
-- **Self-cleaning:** Tests that create data use `t.Cleanup()` to delete it afterward. The seed data is not modified.
-
-## Prerequisites
-
-1. **Docker Compose demo stack running:**
-   ```bash
-   cd deploy
-   docker compose -f docker-compose.yml -f docker-compose.demo.yml up --build -d
-   ```
-   Wait ~15 seconds for health checks to pass.
-
-2. **Go 1.22+** installed (the project uses Go 1.25 in `go.mod`, but 1.22+ works for running tests).
-
-3. **PostgreSQL port exposed** — the demo stack exposes port 5432 for database verification tests (table counts, schema checks).
-
-4. **Repository checkout** — source file verification tests (`fileExists`, `fileContains`) read files relative to `qaRepoDir` (default: `../..` from `deploy/test/`).
-
-## Running the Tests
-
-### Full suite
-```bash
-cd deploy/test
-go test -tags qa -v -timeout 10m ./...
-```
-
-### Single Part
-```bash
-go test -tags qa -v -run TestQA/Part03 ./...
-```
-
-### Single subtest
-```bash
-go test -tags qa -v -run TestQA/Part03_CertCRUD/Create_Minimal ./...
-```
-
-### With custom environment
-```bash
-CERTCTL_QA_SERVER_URL=https://staging.internal:8443 \
-CERTCTL_QA_API_KEY=my-staging-key \
-CERTCTL_QA_DB_URL=postgres://certctl:secret@db.internal:5432/certctl?sslmode=require \
-CERTCTL_QA_REPO_DIR=/path/to/certctl \
-go test -tags qa -v -timeout 10m ./...
-```
-
-### Environment Variables
-
-| Variable | Default | Description |

-| `CERTCTL_QA_DB_URL` | `postgres://certctl:certctl@localhost:5432/certctl?sslmode=disable` | PostgreSQL connection string |
-| `CERTCTL_QA_REPO_DIR` | `../..` | Path to certctl repo root (for source file checks) |
-| `CERTCTL_QA_CA_BUNDLE` | `./certs/ca.crt` | PEM CA bundle pinned for TLS verification. The demo stack's `certctl-tls-init` container writes here. |
-| `CERTCTL_QA_INSECURE` | `false` | Set to `"true"` to skip TLS verification (e.g. before the init container finishes). Never use outside the demo harness. |

-## Coverage by Risk Class
-
-A buyer's QA lead reading this doc wants "where are the existential bugs caught?" — Bundle P / Strengthening #1 surfaces that view directly. The table below classifies each Part by risk class so reviewers can answer the existential-coverage question in one glance.
-
-| Risk class | Description | Parts in scope | Automation status |
-|---|---|---|---|
-| **Existential** (Critical paths — bugs would compromise CA, leak keys, mis-issue, bypass revocation) | Crypto, PKCS#7, local-issuer, OCSP/CRL, agent keygen, CSR validation | 5 (Revocation), 21 (EST), 23 (S/MIME EKU), 24 (OCSP/CRL), 47 (Digest with cert content), 53 (K8s Secrets), 54 (AWS PCA) | 5/7 automated; Parts 23 + 24 pending (Bundle I Skip stubs in `qa_test.go`; manual playbook in the Coverage Map below) |
-| **High** (FSM corruption, credential leak, authn/z weakening) | Renewal, jobs, agents, issuers, deployment, scheduler | 4, 7, 8, 9, 18, 19, 20, 22, 25, 28, 29, 32, 33, 48, 49, 55, 56 | 14/17 automated; CLI / MCP / scheduler-loop are inherently SKIP (require compiled binaries / Docker logs); Parts 55 + 56 pending |
-| **Medium** (Operational pain or silent data drift) | Targets, notifiers, observability, error handling, performance, regression | 14, 15-17, 30, 31, 38, 39, 40, 41, 42, 43, 44, 45, 46 | 14/14 automated (15-17 indirect via Parts 42–46) |
-| **Low** (Hygiene) | Documentation, docs verification | 40 (Documentation), 50 (Onboarding) | 2/2 automated |
-| **Frontend** (XSS, render correctness, mutation contracts) | GUI testing | 35, 36-37 | 0/3 automated in this suite (Vitest covers separately under `web/`); this doc punts to manual + Vitest |
-| **Audit-relevant** | Audit trail, body-size limits, request limits, Helm chart deploy posture | 27, 32, 51, 52 | 4/4 automated |
-
-This is the table acquisition reviewers screenshot for their report. When a new Part_* subtest lands in `qa_test.go`, classify it here.
-
-## Test Categories
-
-The automated tests fall into four categories:
-
-### 1. API Integration Tests (majority)
-Make real HTTP requests to the running server and verify status codes, response structure, and JSON field values. Examples:
-- `POST /api/v1/certificates` with valid payload → 201
-- `GET /api/v1/certificates?status=Active` → all returned certs have `status: "Active"`
-- `DELETE /api/v1/certificates/mc-qa-full` → 204
-
-### 2. Database Verification Tests
-Connect directly to PostgreSQL and verify schema state:
-- Table count ≥ 19 (from migrations 000001–000010)
-- Useful for catching migration regressions
-
-### 3. Source File Verification Tests
-Read files from the repo checkout and verify structure:
-- Domain types exist in `internal/domain/connector.go` (e.g., `TargetTypeEnvoy`)
-- Connector implementations exist (e.g., `internal/connector/target/envoy/envoy.go`)
-- Documentation contains expected content (all issuer/target types listed)
-- No stale RFC 9702 references (replaced by RFC 9773)
-
-### 4. Performance Spot Checks
-Timed API requests with threshold assertions:
-- `GET /api/v1/certificates?per_page=15` < 200ms
-- `GET /api/v1/stats/summary` < 500ms
-- `GET /api/v1/metrics/prometheus` < 300ms
-
-## What This Test Does NOT Cover
-
-These gaps must be filled by manual testing — see each Coverage Map row for surface-area description:
-
-### Not Yet Automated (Parts 23, 24, 55, 56)
-
-These historical QA Parts are listed in the Coverage Map below but have no `Part_*` automation
-in `qa_test.go` yet. They are operator-runnable from the manual playbook; QA-suite
-automation should land before the next acquisition-grade release.
-
-- **Part 23: S/MIME & EKU Support** — profile-driven EKU enforcement; SMIMECapabilities extension
-- **Part 24: OCSP Responder & DER CRL** — OCSP request/response correctness, CRL generation, Must-Staple coordination
-- **Part 55: Agent Soft-Retirement (I-004)** — soft vs hard retire, FK cascade, reactivation
-- **Part 56: Notification Retry & Dead-Letter Queue (I-005)** — retry semantics, dead-letter transition, requeue
-
-### External CA Integrations (Parts 10–13)
-- **Sub-CA mode** — requires CA cert+key files on disk
-- **ACME ARI** — requires a CA that supports RFC 9773 Renewal Information
-- **Vault PKI** — requires a running HashiCorp Vault instance
-- **DigiCert / Sectigo / Google CAS** — requires sandbox API credentials
-
-### Browser/GUI Testing (Parts 35–37, 50)
-- Dashboard chart rendering (Recharts)
-- Onboarding wizard step-by-step flow
-- Issuer catalog card layout and create wizard
-- Bulk operations UI (multi-select, progress bars)
-- Discovery triage workflow
-
-### Real Deployment Testing (Parts 15–17)
-- NGINX/Apache/HAProxy file write + reload
-- Traefik/Caddy file provider or API reload
-- IIS PowerShell/WinRM (requires Windows)
-- F5 BIG-IP iControl REST (requires appliance or mock)
-- SSH agentless deployment (requires target host)
-
-### Agent Binary Behavior (Parts 18, 28–29)
-- Agent-side ECDSA key generation and CSR submission
-- Agent filesystem discovery scan
-- CLI tool (`certctl-cli`) — all 10 subcommands
-- MCP server (`mcp-server`) — stdio transport
-
-### Timing-Dependent Tests (Parts 33–34)
-- Background scheduler loop execution (renewal, jobs, health, notifications, digest, network scan)
-- Structured logging format verification (requires Docker log parsing)
-
-## How This Relates to `integration_test.go`
-
-Both files live in `deploy/test/` in the same Go package (`integration_test`):
-
-| | `qa_test.go` | `integration_test.go` |
-|---|---|---|
-| **Build tag** | `//go:build qa` | `//go:build integration` |
-| **Target stack** | Demo (`docker-compose.yml` + `docker-compose.demo.yml`) | Test (`docker-compose.test.yml`) |
-| **Port** | 8443 | Different (test stack config) |
-| **Seed data** | `seed_demo.sql` (32 certs, 12 agents, 13 issuers, 8 targets, realistic history) | Minimal (created by tests) |
-| **CA backends** | Local CA only (demo mode) | Pebble ACME, step-ca, NGINX |
-| **Purpose** | Release QA — broad coverage, spot checks | Functional — end-to-end issuance, renewal, revocation against real CAs |
-| **Run frequency** | Before each release tag | CI on every PR |
-
-They are complementary. Integration tests prove the machinery works. QA tests prove the product works at release quality.
-
-## Seed Data Reference
-
-The QA tests depend on `migrations/seed_demo.sql`. Key IDs used:
-
-### Certificates (32 total in `managed_certificates`)
-
-The full canonical list is generated by:
-```
-sed -n '/^INSERT INTO managed_certificates/,/^;/p' migrations/seed_demo.sql \
-  | grep -oE "^\s*\('mc-[a-z0-9_-]+" | sed -E "s/^\s*\('//" | sort -u
-```
-
-Hand-listing is unsustainable as the seed grows; tests reference IDs by lookup, not by enumeration.
-Sample IDs: `mc-api-prod`, `mc-web-prod`, `mc-pay-prod`, `mc-compromised`, `mc-smime-bob`, `mc-edge-eu`, `mc-k8s-ingress`, `mc-wildcard-prod`. See `migrations/seed_demo.sql:147` onward.
-
-### Agents (12 total in `agents` table)
-
-8 named workload agents + 1 server-side sentinel + 3 cloud-discovery sentinels:
-
-- **Workload agents:** `ag-web-prod`, `ag-web-staging`, `ag-lb-prod`, `ag-iis-prod`, `ag-data-prod`, `ag-edge-01`, `ag-k8s-prod`, `ag-mac-dev`
-- **Server-side sentinel:** `server-scanner`
-- **Cloud-discovery sentinels:** `cloud-aws-sm`, `cloud-azure-kv`, `cloud-gcp-sm`
-
-Full list via:
-```
-sed -n '/^INSERT INTO agents/,/^;/p' migrations/seed_demo.sql \
-  | grep -oE "^\s*\('[a-z][a-z0-9_-]+" | sed -E "s/^\s*\('//"
-```
-
-(The `agent_groups` table also contains entries with `ag-*` IDs — `ag-linux-prod`, `ag-windows`, `ag-datacenter-a`, `ag-arm64`, `ag-manual` — but those are *group* IDs, not agents. Don't confuse the two.)
-
-### Issuers (13 total)
-
-`iss-local`, `iss-acme-le`, `iss-stepca`, `iss-acme-zs`, `iss-openssl`, `iss-vault`, `iss-digicert`, `iss-sectigo`, `iss-googlecas`, `iss-awsacmpca`, `iss-entrust`, `iss-globalsign`, `iss-ejbca`.
-
-Full list via:
-```
-sed -n '/^INSERT INTO issuers/,/^;/p' migrations/seed_demo.sql \
-  | grep -oE "^\s*\('iss-[a-z0-9_-]+" | sed -E "s/^\s*\('//"
-```
-
-### Targets (8 total in `deployment_targets`)
-`tgt-nginx-prod`, `tgt-nginx-staging`, `tgt-haproxy-prod`, `tgt-apache-prod`, `tgt-iis-prod`, `tgt-traefik-prod`, `tgt-caddy-prod`, `tgt-nginx-data`
-
-### Network Scan Targets (4 total in `network_scan_targets`)
-`nst-dc1-web`, `nst-dc2-apps`, `nst-dmz`, `nst-edge`
-
-**Maintenance note:** when adding new seed rows, also update this section, OR remove the
-per-table counts and rely on the `sed | grep` commands so the doc stops drifting on every
-seed-data change. A CI guard that fails when the doc count diverges from the seed file is
-proposed in `coverage-audit-2026-04-27/tables/qa-doc-strengthening.md` (Strengthening #6).
-
-## Troubleshooting
-
-### "Server unreachable" on startup
-The test pings `GET /health` before running anything. If this fails:
-```bash
-# Check if the stack is running
-docker compose -f docker-compose.yml -f docker-compose.demo.yml ps
-
-# Check server logs
-docker compose -f docker-compose.yml -f docker-compose.demo.yml logs certctl-server
-
-# Check if the port is exposed (self-signed cert — pin CA bundle)
-curl --cacert ./deploy/test/certs/ca.crt -s https://localhost:8443/health
-```
-
-### "connect to QA DB" failure
-The database tests connect directly to PostgreSQL. Ensure port 5432 is exposed:
-```bash
-docker compose -f docker-compose.yml -f docker-compose.demo.yml port postgres 5432
-```
-
-### Performance tests flaking
-The performance thresholds (200ms, 300ms, 500ms) assume a local Docker stack. On slow CI runners or remote Docker hosts, increase the thresholds or skip Part 39:
-```bash
-go test -tags qa -v -run 'TestQA/Part(?!39)' ./...
-```
-
-### Source file checks failing
-The `fileExists` and `fileContains` helpers read from `CERTCTL_QA_REPO_DIR` (default `../..`). If running from a non-standard location:
-```bash
-CERTCTL_QA_REPO_DIR=/absolute/path/to/certctl go test -tags qa -v ./...
-```
-
-## Release Day Sign-Off Matrix
-
-Before tagging a release, the QA-on-call engineer signs off on each row. This matrix replaces the previous ad-hoc release checklist and ties test execution directly to release approval. Acquisition-grade releases have this kind of matrix; the doc previously didn't.

-## Mutation Testing Targets & Kill Rate
-
-Mutation testing exposes which assertions are actually load-bearing — tests can pass against broken code if mutations survive, which is a coverage trap. The audit's Phase 0 attempted to run `go-mutesting` on the Existential cluster but was blocked by a Go 1.25 / arm64 incompatibility in `osutil@v1.6.1` (uses `syscall.Dup2` which is undefined on linux/arm64). The operator-runnable workaround uses a fork that targets `unix.Dup3` instead.
-
-| Package | Risk class | Target kill rate | Last measured | Tool |
-|---|---|---|---|---|
-| `internal/crypto` | Existential | ≥90% | unmeasured (sandbox-blocked, operator-runnable) | go-mutesting |
-| `internal/pkcs7` | Existential | ≥90% | unmeasured | go-mutesting |
-| `internal/connector/issuer/local` | Existential | ≥90% | unmeasured | go-mutesting |
-| `internal/connector/issuer/acme` | Existential | ≥80% (catch-up; failure-mode coverage 55.6% per Bundle J) | unmeasured | go-mutesting |
-| `internal/connector/issuer/stepca` | Existential | ≥85% (post-Bundle-L.B coverage at 90.4%) | unmeasured | go-mutesting |
-| `internal/api/middleware` | High | ≥80% | unmeasured | go-mutesting |
-| `internal/validation` | Existential (CWE-78 / CWE-113 boundary) | ≥90% | unmeasured | go-mutesting |
-| `web/src/utils/safeHtml.ts` | Frontend (XSS gate) | ≥90% | unmeasured | Stryker |
-
-### Operator command (per package)
-
-```bash
-# Use the avito-tech fork that supports linux/arm64 + Go 1.25.
-go install github.com/avito-tech/go-mutesting/cmd/go-mutesting@latest
-
-mkdir -p tool-output
-$(go env GOPATH)/bin/go-mutesting --debug ./internal/crypto/... \
-  > tool-output/mutation-crypto.txt 2>&1
-grep -oE 'mutation score is [0-9.]+' tool-output/mutation-crypto.txt | tail -1

-**Acceptance:** ≥80% (Existential) / ≥70% (High). Anything below is a Medium finding; triage entries go in `coverage-audit-2026-04-27/gap-backlog.md`. This subsection moves mutation testing from "future work" to "documented release gate."
-
-## Adding New Tests
-
-When a new feature ships:
-
-1. **Add a Part section** in `qa_test.go` following the numbering convention in the Coverage Map below
-2. **API tests**: use `c.get()`, `c.post()`, `c.bodyStr()`, `c.getJSON()`, `c.timedGet()`
-3. **Source checks**: use `fileExists(t, "relative/path")` and `fileContains(t, "path", "substring")`
-4. **DB checks**: use `openQADB(t)` and `db.queryInt(t, "SELECT ...")`
-5. **Cleanup**: always use `t.Cleanup()` for data created during tests
-6. **Skip if external**: use `t.Skip("Requires X — manual test")` with a clear reason
-
-## Version History
-
-- **v1.3** (April 2026, post-Bundle-P) — QA Doc Strengthening shipped. New top-of-doc Test Suite Health dashboard (regenerated via `make qa-stats`). New Coverage by Risk Class table after the Coverage Map. New Release Day Sign-Off Matrix and Mutation Testing Targets sections. CI seed-count + Part-count drift guards land in `.github/workflows/ci.yml` so future doc drift fails CI. Bundle P closes M-007 / M-010 / M-011 / M-012 (structural strengthening) + M-008 (Mutation Testing Targets).
-- **v1.2** (April 2026, post-coverage-audit) — Documented Parts 55–56 (I-004 Agent Soft-Retirement, I-005 Notification Retry & Dead-Letter) and surfaced Parts 23–24 (S/MIME & EKU; OCSP/CRL) as not-yet-automated. 56 Parts total in `testing-guide.md`; 49 live `Part_*` automation wrappers in `qa_test.go` + 4 new `Skip` stubs for Parts 23/24/55/56 = 53 wrappers (Parts 15–17 remain covered by source-checks in Parts 42–46). Reconciled seed-data section to actual `seed_demo.sql` counts (12 agents, 13 issuers; certs were already accurate at 32). Bundle I of the 2026-04-27 coverage-audit closure plan.
-- **v1.1** (April 2026) — Added Parts 53–54 (M47: Kubernetes Secrets target + AWS ACM PCA issuer). 54 Parts total, ~164 automated subtests.
-- **v1.0** (April 2026) — Initial release covering all 52 Parts of testing-guide.md v2.1. Replaces `qa-smoke-test.sh`.

-# certctl Testing Strategy & Deep-Scan Operator Runbook
-
-> Last reviewed: 2026-05-05
-
-This doc covers the **testing topology** (per-PR fast gates vs. daily deep-scan
-gates), and the **operator runbook** for re-running each deep-scan tool locally
-when the CI receipt is ambiguous or when an operator wants to validate a fix
-before the next scheduled scan.
-
-For the manual end-to-end QA playbook, see [`testing-guide.md`](../testing-guide.md).
-For the security posture / per-finding closure log, see [`security.md`](../operator/security.md).
-
-## CI workflow split
-
-certctl runs two GitHub Actions workflows:
-
-- **`.github/workflows/ci.yml`** — runs on every push/PR. Fast feedback only.
-  Includes `gofmt`, `go vet`, `golangci-lint`, `go test -short -count=1`,
-  `govulncheck`, the per-layer coverage gates, and the regression-grep guards
-  (the M-009 mutation budget, the L-001 InsecureSkipVerify guard, the H-001
-  Dockerfile SHA-pin guard, the M-012 USER-directive guard, etc.).
-- **`.github/workflows/security-deep-scan.yml`** — runs daily 06:00 UTC and on
-  manual dispatch. Heavyweight tools that need docker, network egress to
-  scanner registries, or wall-clock budgets the per-PR check can't tolerate.
-  Includes `gosec`, `osv-scanner`, the `-race -count=10` full-suite run,
-  `trivy` image scan, `syft` SBOM, ZAP baseline DAST, `nuclei`,
-  `schemathesis` OpenAPI fuzz, `testssl.sh`, `go-mutesting` mutation testing,
-  and `semgrep p/react-security`.
-
-Receipts from each scheduled run are uploaded as a 30-day-retention artefact
-named `security-deep-scan-<run-id>`. Audit them via the GitHub Actions UI;
-download the artefact zip for any scan that surfaces a finding.
-
-## Operator runbook — local re-run procedures
-
-These are the same commands the workflow runs, intended for an operator with
-a workstation that has docker + the Go toolchain installed. The local-run
-shape is identical to CI; the difference is wall-clock and the artefact
-location (CI uploads; local writes to `$PWD`).
-
-### Mutation testing (D-003)
-
-**Tool:** [`go-mutesting`](https://github.com/zimmski/go-mutesting). Mutates
-each AST node in turn (flips comparisons, swaps return values, removes
-statements) and re-runs the package's tests. A mutant is **killed** if any
-test fails; **surviving** mutants indicate a coverage gap (no test caught
-the bug the mutant introduced).
-
-**Targets:** the three security-critical packages whose coverage gate is
-**85%** in `ci.yml`:
-
-- `internal/crypto/`
-- `internal/pkcs7/`
-- `internal/connector/issuer/local/`
-
-**Acceptance threshold:** ≥80% mutation kill ratio per package. Surviving
-mutants below that threshold get triaged in
-the project's 2026-04-25 mutation-results notes — either
-ship a targeted unit test that kills the mutant, or document an
-equivalent-mutation justification.
-
-**Local run:**
-
-```
-go install github.com/zimmski/go-mutesting/cmd/go-mutesting@latest
-for pkg in ./internal/crypto/... ./internal/pkcs7/... ./internal/connector/issuer/local/...; do
-  echo "=== $pkg ==="
-  $(go env GOPATH)/bin/go-mutesting "$pkg"
-done
-```
-
-The tool prints one line per mutant (`PASS` = killed, `FAIL` = surviving)
-plus a per-package summary `The mutation score is X.YZ`. CPU-bound, single
-core, takes ~10 minutes on a 2024-era laptop for the three packages combined.
-
-**Sandbox note:** `go-mutesting` writes a mutant copy of the source tree to
-`/tmp/go-mutesting/` per run; needs ≥2 GB free disk. Sandboxed CI runners
-are sized for this; constrained dev sandboxes are not.
-
-### DAST baseline (D-004)
-
-**Tool:** [OWASP ZAP `baseline`](https://www.zaproxy.org/docs/docker/baseline-scan/).
-Spiders the running server's URL surface and runs the OWASP-ZAP active+passive
-rule pack. **Baseline** mode skips the destructive active-scan rules; it's safe
-against a non-throwaway environment.
-
-**Target:** the live `deploy/docker-compose.yml` stack on `https://localhost:8443`.
-
-**Acceptance:** zero HIGH/CRITICAL alerts. WARN/INFO alerts get triaged in the
-ZAP report; some are unavoidable (e.g., HSTS preload-list nag is a deployment
-recommendation, not a server defect).
-
-**Local run:**
-
-```
-docker compose -f deploy/docker-compose.yml up -d
-sleep 20  # wait for /ready to flip OK; check `curl --cacert deploy/test/certs/ca.crt https://localhost:8443/ready`
-docker run --rm --network host \
-  -v "$PWD":/zap/wrk \
-  ghcr.io/zaproxy/zaproxy:stable \
-  zap-baseline.py -t https://localhost:8443 \
-  -r zap-report.html -J zap-report.json
-docker compose -f deploy/docker-compose.yml down
-```
-
-The HTML report opens in a browser; the JSON is machine-readable for triage.
-
-### TLS audit (D-005)
-
-**Tool:** [`testssl.sh`](https://testssl.sh/). Probes the TLS handshake and
-each enabled cipher suite; reports protocol-version weaknesses, cipher
-weaknesses, certificate-chain issues, and known CVE patterns (Heartbleed,
-ROBOT, BEAST, etc.).
-
-**Target:** the live stack on `https://localhost:8443`.
-
-**Acceptance:** zero HIGH/CRITICAL findings. certctl pins
-`tls.Config.MinVersion = tls.VersionTLS13` (`cmd/server/tls.go`), so anything
-that surfaces is either (a) a real defect, (b) a testssl false positive, or
-(c) a deployment-config issue worth documenting in the operator runbook.
-
-**Local run:**
-
-```
-docker compose -f deploy/docker-compose.yml up -d
-sleep 20
-docker run --rm --network host \
-  -v "$PWD":/data \
-  drwetter/testssl.sh:latest \
-  --jsonfile /data/testssl.json https://localhost:8443
-docker compose -f deploy/docker-compose.yml down
-
-# Filter to actionable severities
-jq '[.scanResult[] | select(.severity == "HIGH" or .severity == "CRITICAL")]' testssl.json
-```
-
-### Frontend semgrep (D-007)
-
-**Tool:** [`semgrep`](https://semgrep.dev/) with the maintained
-[`p/react-security` ruleset](https://semgrep.dev/p/react-security). Catches
-React-specific XSS / injection patterns: `dangerouslySetInnerHTML` without
-sanitization, `target="_blank"` without `rel="noopener noreferrer"`,
-`href={userInput}`, `eval`, `document.write`, etc.
-
-**Target:** the frontend source tree at `web/src/`.
-
-**Acceptance:** zero findings. Bundle 8 already verified
-`dangerouslySetInnerHTML` count at zero and the `target="_blank"`
-rel-noopener pin via simple grep guards in `ci.yml`; semgrep adds defence
-in depth — it catches escape patterns the greps don't see (e.g.,
-`href={user_input}`, runtime `eval`, `document.write`).
-
-**Local run:**
-
-```
-docker run --rm -v "$PWD":/src returntocorp/semgrep:latest \
-  semgrep --config=p/react-security --json /src/web/src \
-  > semgrep-react.json
-
-# Count findings
-jq '.results | length' semgrep-react.json
-
-# Pretty-print findings
-jq '.results[] | {rule_id: .check_id, path, line: .start.line, message: .extra.message}' semgrep-react.json
-```
-
-If the count is non-zero, every result has a `check_id` (e.g.
-`react.dangerouslySetInnerHTML`) and a `message` describing the escape
-pattern. Triage each: either fix the call site, or — for legitimate edge
-cases — add a `// nosem: <check_id> — <reason>` directive on the
-preceding line.
-
-## Cadence
-
-| Tool                 | Trigger                            | Wall-clock | Owner          |

-Re-run any of the deep-scan tools locally when:
-
-- A CI receipt surfaces an unexpected finding and you want to bisect against
-  a local change before pushing.
-- You're cutting a release tag and want belt-and-suspenders evidence beyond
-  the most recent scheduled scan.
-- You're adding a new feature in the relevant surface (crypto code →
-  re-run mutation testing; new HTTP handler → re-run schemathesis + ZAP;
-  new TLS-config knob → re-run testssl).

+# Git history normalization — 2026-05-13
+
+> Last reviewed: 2026-05-13
+
+This page documents a one-time normalization of certctl's git history
+that landed on `master` on 2026-05-13. If you are reading this because
+your clone failed to fast-forward, or because a commit SHA you bookmarked
+no longer resolves, this is the explanation.
+
+## What changed
+
+Every commit's `author` and `committer` metadata was rewritten to a
+single canonical identity (`shankar0123 <skreddy040@gmail.com>`). The
+14 pre-rewrite author identities — operator name variants plus
+AI/automation identities (Claude, Copilot, cowork agent, certctl-bot,
+etc.) — collapsed to that one canonical author.
+
+No source-code content was changed by the rewrite. Every line of code
+in every commit is byte-for-byte identical to its pre-rewrite version.
+Only the `author` and `committer` metadata fields were touched; commit
+messages, subject lines, milestone IDs (M49, L-1, etc.), and every
+other line of every commit's body are preserved verbatim.
+
+## Why
+
+Two reasons:
+
+1. **LLC ownership transfer.** The codebase is now legally owned by
+   **certctl LLC**, which the operator incorporated to hold rights in
+   the project. The BSL 1.1 Licensor field in `LICENSE` flipped from a
+   natural-person name to `certctl LLC` in the same change set. Uniform
+   per-commit authorship under one canonical operator identity makes
+   the chain of title between the codebase and the LLC unambiguous.
+
+2. **Pre-traction cleanup.** The rewrite cost of git-history
+   normalization scales with how many external clones and references
+   have calcified against specific commit SHAs. Doing it now, before
+   the project has a large external surface, minimizes disruption to
+   downstream consumers.
+
+## What is preserved
+
+A complete off-platform bundle backup of the pre-rewrite tree is held
+by the operator (off-repo, not pushed). It contains every original
+commit SHA, every original author identity, and the full ref graph as
+it existed before the rewrite. The bundle is the immutable
+preservation record and is recoverable forever.
+
+An `archive/pre-author-normalization-2026-05-13` tag briefly existed
+on origin pointing at the pre-rewrite tip but was removed when the
+operator opted to clean the contributor graph of pre-rewrite
+authorship signal. The bundle remains as the canonical archive — any
+forensic question about pre-rewrite state can be answered by loading
+the bundle into a fresh clone (`git clone pre-rewrite-2026-05-13.bundle`).
+
+## Recovering after the rewrite
+
+If you had a clone of certctl from before 2026-05-13, your local
+history diverged from origin's at the rewrite. Easiest recovery:
+
+```bash
+cd certctl
+git fetch origin
+git fetch origin --tags
+git reset --hard origin/master
+```
+
+This force-aligns your local tree with the new origin. Any local
+branches you had based on pre-rewrite history will need rebasing onto
+the new master.
+
+If you need to inspect the pre-rewrite state for a forensic or
+diligence question, contact the operator directly — the off-platform
+bundle is the canonical archive and is available on request.
+
+## Container images and release tarballs
+
+ghcr.io container images that were published before the rewrite
+(`ghcr.io/certctl-io/certctl-{server,agent}:<old-tag>`) remain pullable
+indefinitely. Their OCI source-SHA labels reference commit SHAs that
+no longer resolve in the public origin — the images themselves still
+work; only the source-SHA back-reference is now orphan. New release
+images published after the rewrite reference current SHAs normally.
+
+If you downloaded a release tarball before the rewrite, the tarball's
+contents are unchanged; only its associated `git` SHA differs from the
+current `v2.x.y` tag (which has been re-pointed to the rewritten
+commit at the same logical point in history).
+
+## Operational note for contributors
+
+Future contributions to certctl should be authored under the
+operator's canonical git identity. Pull requests from external
+contributors will need a Contributor License Agreement (CLA) workflow,
+which the project will set up before accepting external PRs. Until
+then, the project does not solicit or accept external code
+contributions.

+# Enable OIDC SSO
+
+> Last reviewed: 2026-05-10
+
+This guide walks an operator already running certctl with API-key auth + RBAC through enabling OIDC SSO. The path is additive: API-key auth keeps working unchanged; OIDC sits alongside as a second authentication surface for human users.
+
+If you are upgrading from a pre-RBAC (v2.0.x) deployment, finish [`api-keys-to-rbac.md`](api-keys-to-rbac.md) first. If you have not deployed certctl at all, start with [`getting-started/quickstart.md`](../getting-started/quickstart.md). For the canonical mental model + per-flow threat coverage, see [`security.md`](../operator/security.md) and [`auth-threat-model.md`](../operator/auth-threat-model.md).
+
+## What "enable OIDC" gives you
+
+After this migration:
+
+- Human operators can log in via the OIDC button on the certctl login page (one button per configured IdP).
+- The IdP authenticates the user; certctl validates the returned ID token, mints a session cookie, and redirects to the dashboard.
+- IdP groups → certctl roles are operator-configured (e.g. `engineering@example.com` → `r-operator`).
+- Every login emits an audit row (`auth.oidc_login_succeeded`) attributing the action to the federated user, NOT to a shared API key.
+- The first user from a configured admin group (when `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` is set) becomes admin per tenant; one-shot per the admin-existence probe.
+
+What does NOT change:
+
+- API keys keep working. Existing automation continues to authenticate via `Authorization: Bearer` exactly as before.
+- The break-glass admin path stays default-OFF.
+- The auditor split + approval workflow + RBAC primitive are unchanged.
+
+## Pre-requisites
+
+**On certctl side:**
+
+- Server build ≥ v2.1.0. Confirm via `curl https://<your-host>:8443/api/v1/version`.
+- `CERTCTL_CONFIG_ENCRYPTION_KEY` set in the server environment. This is the passphrase that encrypts the OIDC `client_secret` at rest. Use a stable, secrets-manager-stored value at least 32 random bytes long. **The server refuses to start if the key is missing AND any source='database' rows already exist** (CWE-311 fail-closed gate). Set this before doing anything else.
+- An admin actor available to drive the configuration. The actor needs the `auth.oidc.create` + `auth.oidc.edit` permissions; `r-admin` carries both by default. Get one via the day-0 bootstrap path if you don't have one yet.
+- HTTPS-only control plane (post-v2.2 milestone — this is the default). The OIDC redirect URI MUST be `https://`.
+
+**On IdP side:**
+
+- A Keycloak / Authentik / Okta / Auth0 / Entra ID / Google Workspace tenant where you can register an OIDC application. Free dev tiers work for evaluation. See the per-IdP runbook at [`oidc-runbooks/index.md`](../operator/oidc-runbooks/index.md).
+- Network reachability from certctl-server to the IdP's `/.well-known/openid-configuration` discovery endpoint. The certctl service fetches discovery + JWKS at provider creation and at every `RefreshKeys` call.
+
+## Step-by-step
+
+### 1. Pin `CERTCTL_CONFIG_ENCRYPTION_KEY`
+
+If your deployment already has it set (the CWE-311 fail-closed gate enforces this for any source='database' issuer/target row), skip this step. If you don't:
+
+```bash
+# Generate a 32-byte random key + base64-encode it.
+openssl rand -base64 32 > /etc/certctl/config-encryption-key
+chmod 600 /etc/certctl/config-encryption-key
+```
+
+Then make the server consume it at boot:
+
+```bash
+# In your environment, systemd unit, k8s Secret, etc.
+export CERTCTL_CONFIG_ENCRYPTION_KEY="$(cat /etc/certctl/config-encryption-key)"
+```
+
+Restart the server. Confirm the boot log does NOT show the `ErrEncryptionKeyRequired` warning. If it does, the server refuses to start because there's pre-existing source='database' material that needs to be re-sealed; see [`docs/operator/security.md`](../operator/security.md) for the re-encryption flow.
+
+### 2. Pick an IdP runbook + complete the IdP-side configuration
+
+Pick the runbook for your IdP and do EVERYTHING in its IdP-side section. The runbooks are at [`docs/operator/oidc-runbooks/`](../operator/oidc-runbooks/index.md). What you need from the runbook before continuing here:
+
+- The IdP's discovery URL (the `iss` value certctl will validate against).
+- An OIDC client ID + client secret. Save the secret; you'll paste it into certctl in step 3.
+- At least one IdP group with the users who should be allowed to log in. The runbook walks the group-claim mapper config.
+- The IdP-side group claim shape — most IdPs emit `string-array` under a `groups` key, but Auth0 uses namespaced URL keys (`https://your-namespace/groups`) and Entra ID emits group OBJECT IDs (GUIDs) instead of names. The runbook calls out the per-IdP shape.
+
+### 3. Configure the certctl-side OIDC provider
+
+Via the GUI (recommended for first-time setup):
+
+1. Sign in as an admin actor.
+2. Navigate to **Auth → OIDC Providers** in the sidebar.
+3. Click **Configure provider**.
+4. Fill in the form using the values from step 2's runbook.
+5. Click **Save**.
+
+If the discovery doc fetch fails, the modal surfaces the error inline. Most-common cause: a typo in the issuer URL.
+
+Or via the CLI / MCP:
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Keycloak",
+    "issuer_url": "https://keycloak.example.com/realms/certctl",
+    "client_id": "certctl",
+    "client_secret": "<paste-the-secret>",
+    "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+    "groups_claim_path": "groups",
+    "groups_claim_format": "string-array",
+    "scopes": ["openid", "profile", "email"],
+    "iat_window_seconds": 300,
+    "jwks_cache_ttl_seconds": 3600
+  }'
+```
+
+The MCP equivalent (`certctl_auth_create_oidc_provider`) accepts the same JSON shape.
+
+### 4. Add the group → role mappings
+
+Empty mapping list = nobody can log in via this provider (the fail-closed contract; pinned by `ErrGroupsUnmapped`). Add at least one mapping BEFORE announcing the SSO endpoint to users.
+
+Via the GUI: **Auth → OIDC Providers → <provider> → Group → role mappings → Add**.
+
+Via the API:
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/group-mappings \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "provider_id": "<provider-id-from-step-3>",
+    "group_name": "engineering@example.com",
+    "role_id": "r-operator"
+  }'
+```
+
+A typical setup adds two or three mappings: `engineers → r-operator`, `viewers → r-viewer`, optionally `admins → r-admin`. For Entra ID, use group object IDs (GUIDs) NOT names; for Auth0, use the bare group name from inside the namespaced claim array.
+
+### 5. (Optional) Configure first-admin bootstrap
+
+If your deployment has no admin actor yet AND you want the first OIDC-authenticated user from a specific group to become admin (instead of using the env-var-token bootstrap path), set:
+
+```bash
+export CERTCTL_BOOTSTRAP_ADMIN_GROUPS=admins
+export CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID=<provider-id-from-step-3>
+```
+
+Restart the server. The first user with the `admins` group claim from that provider becomes admin on login per tenant. Subsequent logins go through normal group-role mapping. Audit row on every grant (`bootstrap.oidc_first_admin`).
+
+If you already have an admin actor (likely — you needed one to run step 3), the bootstrap hook silently falls through to normal mapping; no harm done. The probe is one-shot per tenant and can't double-grant.
+
+### 6. Verify with a single test user
+
+Before announcing the SSO endpoint to your users, verify the full login flow with a test user from your IdP:
+
+1. Open `https://<your-certctl-host>:8443/login` in a fresh incognito window.
+2. The page should render `Sign in with <provider>` button(s) above the API-key form. If not, check that `getAuthInfo` is returning the `oidc_providers` field — `curl https://<your-host>:8443/api/v1/auth/info` should show the configured provider(s).
+3. Click the provider button. The browser redirects to the IdP, you authenticate, and the IdP redirects back. You should land on the certctl dashboard.
+4. Navigate to **Auth → Sessions**. You should see a row with your own actor ID and the current timestamp.
+5. Confirm the audit row:
+
+   ```bash
+   curl https://<your-host>:8443/api/v1/audit?category=auth \
+     -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+     | jq '.events[] | select(.action == "auth.oidc_login_succeeded")'
+   ```
+
+   You should see a row attributed to the federated user with `details.provider_id` matching your configuration.
+
+If any step fails, see the **Troubleshooting** section below.
+
+### 7. Announce the SSO endpoint
+
+Once step 6 passes, the SSO endpoint is operational. Tell your users to log in via `https://<your-host>:8443/login` and click the provider button. API-key auth continues to work for automation; the two paths coexist.
+
+Optional GUI hardening:
+
+- If you want the API-key form hidden once OIDC is configured, the operator can add a frontend feature flag in a follow-on commit. Default behavior keeps both paths visible (the API-key form stays for break-glass + Bearer-mode deploys).
+- If you want to revoke a user's session immediately (e.g. an employee left), use **Auth → Sessions → All actors (admin) → <user> → Revoke**. The next request from that user's browser fails 401.
+
+## Rollback
+
+If you need to disable OIDC:
+
+1. Delete every group-role mapping for the provider:
+   ```bash
+   # GUI: Auth → OIDC Providers → <provider> → Group → role mappings → Remove (each)
+   ```
+2. Delete the OIDC provider:
+   ```bash
+   # GUI: Auth → OIDC Providers → <provider> → Delete (type-confirm-name dialog)
+   ```
+   The server returns HTTP 409 if any user has an authenticated session minted via this provider; revoke those sessions first.
+3. The `Sign in with <provider>` button disappears from the login page on the next `getAuthInfo` round-trip (typically the next page load).
+4. Existing sessions continue to work until idle/absolute expiry. To force-revoke them, **Auth → Sessions → All actors (admin) → revoke each row**.
+
+API-key auth continues to work throughout this rollback; you do not need to re-bootstrap or change any other configuration.
+
+## Troubleshooting
+
+**"Discovery doc fetch failed" at provider creation.**
+The most common cause is a typo in the issuer URL. Curl the URL manually:
+```bash
+curl -v https://<idp-host>/<path>/.well-known/openid-configuration
+```
+If that returns 404, fix the issuer URL.
+
+**"IdP downgrade-attack defense" rejected provider creation.**
+Your IdP advertises HS256/HS384/HS512 or `none` in `id_token_signing_alg_values_supported`. Configure the IdP to advertise only RS256 / RS512 / ES256 / ES384 / EdDSA before re-creating the provider in certctl. The relevant runbook section walks this.
+
+**Login redirects to IdP, user authenticates, but the callback redirects back to `/login` with "no roles assigned".**
+The user authenticated successfully but their groups didn't match any configured mapping (`ErrGroupsUnmapped`). Check:
+- The user is a member of the IdP group you mapped.
+- The group-claim mapper is configured correctly at the IdP (the runbook walks per-IdP).
+- The group name in your certctl mapping exactly matches what the IdP emits — case-sensitive, no leading slash for Keycloak full-path-OFF.
+
+Decode the ID token at jwt.io against the IdP's JWKS to see exactly what's in the `groups` claim.
+
+**`ErrIssuerMismatch` even though the discovery doc looks correct.**
+The `iss` claim in the ID token must match `OIDCProvider.IssuerURL` byte-for-byte. Some IdPs include / omit a trailing slash; check the per-IdP runbook section on `iss` formatting.
+
+**`oidc: pre-login session not found or already consumed`.**
+The user clicked the OIDC login button, then the browser tab idled past the 10-minute pre-login TTL OR the user opened the IdP login in a new tab and consumed the row from the first one. Have them retry from the login page.
+
+**`oidc: state parameter mismatch (replay or forgery)`.**
+Either the user double-submitted a callback URL (clicked it twice from email or browser history), or a CSRF attempt. The pre-login row is single-use; second consumption returns `ErrPreLoginNotFound`. Have them retry from the login page.
+
+**`Sessions revoked but the user can still hit the API.`**
+Check the session contract: the cookie is HMAC-validated on every request, but the actual database row is what `Revoke` deletes. If your reverse proxy is caching the response or the `__Host-certctl_session` cookie wasn't actually cleared on the client, the cookie hits the server's session middleware which returns 401 on the missing-row lookup. The middleware never serves stale data; the issue is upstream of certctl in this case.
+
+**JWKS rotation: an IdP rotated its signing key and existing users start failing login.**
+Click **Refresh discovery cache** on the OIDC provider detail page (or `POST /api/v1/auth/oidc/providers/<id>/refresh`). The certctl service re-fetches discovery + JWKS. New tokens validate immediately. The Keycloak integration test exercises this drill end to end.
+
+**Database row count drift.**
+After OIDC is live, expect to see new rows under:
+- `oidc_providers` (one per configured provider)
+- `group_role_mappings` (one per configured mapping)
+- `users` (one per first OIDC-authenticated user; certctl auto-upserts on login)
+- `sessions` (one per logged-in browser session; idle 1h / absolute 8h GC)
+- `session_signing_keys` (one active + retained-history rows post rotation)
+- `oidc_pre_login_sessions` (transient; 10-minute TTL, scheduler-GC'd)
+
+All ten of these tables are tenant-scoped (`tenant_id` column); single-tenant deployments use the seeded `t-default` tenant.
+
+## What you can do next
+
+- Run [`docs/operator/oidc-runbooks/<your-idp>.md`](../operator/oidc-runbooks/index.md) end to end to fill in the validation checklist + sign-off line.
+- Read [`docs/operator/auth-benchmarks.md`](../operator/auth-benchmarks.md) for the steady-state + cold-cache performance baselines.
+- Review the [`auth-threat-model.md`](../operator/auth-threat-model.md) OIDC + sessions + break-glass sections to understand the failure modes the federated-identity surface defends against.
+- Schedule a rotation reminder for the OIDC `client_secret` (typically 6-12 months; the IdP doesn't auto-rotate it). Edit the provider via the GUI when the time comes; leaving `client_secret` blank in the edit form preserves the existing ciphertext, providing a value rotates.
+
+## `__Host-` cookie rename (BREAKING)
+
+v2.1.0 carries a wire-format change to the three auth cookies: they now carry the `__Host-` prefix. The cookie names are:
+
+- `__Host-certctl_session` (was `certctl_session`)
+- `__Host-certctl_csrf` (was `certctl_csrf`)
+- `__Host-certctl_oidc_pending` (was `certctl_oidc_pending`)
+
+The rename gains browser-enforced subdomain-takeover defense: a `__Host-*` cookie can only be set with `Path=/` + `Secure` + no `Domain` attribute, and the browser rejects any subdomain attempt to overwrite it. The protection is free (the existing cookies already met the prerequisites) but the wire-format change means:
+
+- **Every active session is invalidated by the deploy that lands this change.** Operators see one re-authentication prompt; subsequent logins issue the new `__Host-*`-prefixed cookie.
+- **The pre-login cookie's Path widens from `/auth/oidc/` to `/`** — required by the `__Host-` prefix. The cookie lifetime is unchanged (10 minutes) and is only ever consumed by the callback handler; the wider path scope is harmless.
+- **No operator action required beyond accepting the one-time re-login window.** The GUI's CSRF cookie reader was updated in lockstep; existing bookmarked deep links work without modification.
+
+If you have GUI customizations that read `document.cookie` directly, update them to look for `__Host-certctl_csrf` (the lookup in `web/src/api/client.ts` is the in-tree reference).

+## Enforcement invariants (COMP-006 closure)
+
+Acquisition-audit COMP-006 closure (Sprint 7 ACQ, 2026-05-16). The audit flagged COMP-006 as UNKNOWN because it couldn't independently verify that the approval workflow was bullet-tight — i.e., that a denied approval definitely results in NO certificate being signed, and an approved approval definitely lets the issuance proceed. This subsection documents the enforcement chain end-to-end and names the tests that pin each layer.
+
+**Layer 1 — Issuance gate.** `internal/service/certificate.go::CertificateService.Create` (around L341-373) reads `CertificateProfile.RequiresApproval`. When true, the created Job is stamped `JobStatusAwaitingApproval` (not `Pending`), AND a parallel `ApprovalRequest` row is created. The job processor never touches `AwaitingApproval` rows.
+
+**Layer 2 — Approval state machine.** `internal/service/approval.go::ApprovalService.Reject` and `Approve` flip the approval row + the job row atomically:
+
+- `Reject` → approval=`Rejected`, job=`Cancelled` (pinned by `internal/service/approval_test.go::TestApproval_Reject_TransitionsJobFromAwaitingApprovalToCancelled`).
+- `Approve` → approval=`Approved`, job=`Pending` (pinned by `TestApproval_Approve_TransitionsJobFromAwaitingApprovalToPending`).
+
+The "already terminal" guard (`TestApproval_Approve_RejectsAlreadyDecided`) prevents a rejected approval from later being flipped to approved.
+
+**Layer 3 — Job claim filter (the LOAD-BEARING SQL invariant).** `internal/repository/postgres/job.go::JobRepository.ClaimPendingJobs` (around L296-310) issues:
+
+```sql
+SELECT ... FROM jobs WHERE status = $1
+```
+
+with `$1 = JobStatusPending`. Cancelled jobs are therefore **never** returned to `ProcessPendingJobs`, so the certificate-issuance call path (the only path that signs certs) is unreachable for a denied approval. This SQL filter is the load-bearing "no cert if denied" enforcement — Layer 2 transitions the job to `Cancelled`, Layer 3 ensures `Cancelled` jobs are inert.
+
+**Composition pin.** `internal/service/approval_test.go::TestApproval_COMP006_DenyChainPinsNoCertIfRejected` and `TestApproval_COMP006_ApproveChainPinsJobReachesPending` re-attest the Layer-2-to-Layer-3 handoff in a single named test pair for future auditors. A refactor that, e.g., silently transitioned a denied approval's job to `Pending` instead of `Cancelled` would trip these tests before shipping.

+
+Sprint 6 COMP-001-HASH closure. The `audit_events` table has two
+layered defenses against history rewrites:
+
+| Layer | Migration | What it blocks |
+|---|---|---|
+| **WORM trigger** | `000018_audit_events_worm.up.sql` | The application role cannot `UPDATE` or `DELETE` rows (tamper-**prevention**). |
+| **Hash chain** | `000047_audit_events_hash_chain.up.sql` | A compliance superuser (DB-superuser-equivalent) who bypasses the WORM trigger CAN still rewrite rows, but the rewrite is **detectable** — every subsequent `audit_events_verify_chain()` walk reports the first broken row's id + position (tamper-**evidence**). |
+
+This document covers the hash-chain layer. The WORM layer is
+documented inline in `migrations/000018_audit_events_worm.up.sql`.
+
+## Why a hash chain in addition to WORM
+
+The WORM trigger documents (in its header comment) that a compliance
+superuser role exists by design — backup-restore, retention purges,
+and breach-recovery operators need a way through. Without a hash
+chain, that role can rewrite any row's `actor` / `action` / `details`
+content with no on-disk trace.
+
+HIPAA §164.312(b), FedRAMP AU-9, and NIST 800-53 AU-10 want
+tamper-**evidence**, not just tamper-prevention. The hash chain
+provides it: every row carries a `row_hash = sha256(prev_hash || id
+|| actor || actor_type || action || resource_type || resource_id
+|| details::text || timestamp_iso8601_utc || event_category)`, and
+the genesis row's `prev_hash` is `NULL`. Mutating any field in any
+row breaks the chain at that row's position; the verifier returns
+the first break.
+
+## The verifier function
+
+`audit_events_verify_chain()` is a STABLE plpgsql function shipped
+in migration 000047. It walks every row in `(timestamp ASC, id ASC)`
+order, recomputes each row's expected hash, and returns:
+
+```
+first_break_id  TEXT  -- NULL if the chain validated end-to-end
+first_break_pos INT   -- 0-indexed position of the first break
+row_count       INT   -- rows walked (= position + 1 on break, else table size)
+```
+
+Call it directly from psql:
+
+```sql
+SELECT first_break_id, first_break_pos, row_count FROM audit_events_verify_chain();
+```
+
+## Scheduled verification + Prometheus exposure
+
+The scheduler's `auditChainVerifyLoop` calls the verifier every
+`CERTCTL_AUDIT_CHAIN_VERIFY_INTERVAL` (default 6h) and writes the
+results into the `AuditChainCounter` instance shared with the
+metrics handler. Four metrics get exposed at
+`/api/v1/metrics/prometheus`:
+
+| Metric | Type | Meaning |
+|---|---|---|
+| `certctl_audit_chain_break_detected_total` | counter | Sticky once non-zero — the actionable alarm. |
+| `certctl_audit_chain_verify_total` | counter | Walks completed. Cross-check that the loop is alive. |
+| `certctl_audit_chain_rows` | gauge | Most recent walk's row count. |
+| `certctl_audit_chain_last_verified_at` | gauge | Unix seconds of most recent walk (0 = never). |
+
+The recommended alert rule is:

+
+Cross-check `certctl_audit_chain_last_verified_at` (should advance
+roughly every `CERTCTL_AUDIT_CHAIN_VERIFY_INTERVAL`) and
+`certctl_audit_chain_verify_total` (should increment monotonically).
+A stalled `_verified_at` with an unchanged `_verify_total` means the
+scheduler loop has died — page on that too.
+
+## Performance notes
+
+The walk is `O(N)` plpgsql over the `audit_events` table. On
+testcontainers + postgres:16-alpine the cost scales linearly:
+
+| Row count | Walk duration (approx) |
+|---|---|
+| 10k | < 50 ms |
+| 100k | < 500 ms |
+| 1M | 2-3 s |
+| 10M | 25-30 s |
+
+A 5-minute per-tick context timeout (in
+`internal/scheduler/scheduler.go::runAuditChainVerify`) bounds the
+worst case. Fleets with > 10M audit rows should consider:
+
+1. Lengthening `CERTCTL_AUDIT_CHAIN_VERIFY_INTERVAL` to 24h.
+2. Pre-aggregating older rows (out of scope today — would require a
+   "chain checkpoint" concept that re-anchors the genesis hash to a
+   snapshot's row_hash; future work if needed).
+
+## What to do when a break is detected
+
+1. **Don't panic, don't auto-remediate.** The break is a forensic
+   signal, not a self-healing event.
+2. **Capture the position + id.** The metric exposes both, but the
+   sticky in-memory state (`AuditChainCounter.BrokenAtID`) only
+   records the first break. SQL the verifier yourself to enumerate
+   downstream breaks:
+
+   ```sql
+   SELECT first_break_id, first_break_pos, row_count FROM audit_events_verify_chain();
+   ```
+
+3. **Snapshot the table.** `pg_dump --table=audit_events --data-only`
+   to a chain-of-custody location. The next investigative step is
+   recovering the original row content from the most recent backup
+   that pre-dates the tampering — without this snapshot you can't
+   tell which write order caused the divergence.
+4. **Audit the compliance-superuser credential trail.** The break
+   implies someone with non-app DB credentials wrote to
+   `audit_events`. Rotate the credential, investigate every recent
+   session that authenticated under it, and review the WAL for the
+   write.
+5. **Restore + cross-reference.** If you keep streaming WAL or
+   periodic snapshots, restore a known-good snapshot to a sandbox
+   and `EXCEPT`-diff the two `audit_events` tables to enumerate
+   every mutated row.
+
+## Backfill behavior
+
+Migration 000047 backfills existing `audit_events` rows in
+`(timestamp ASC, id ASC)` order during its transaction. The WORM
+trigger is temporarily `DISABLE`d for the duration; subsequent
+`ENABLE` is a no-op equivalent. The migration is idempotent — a
+re-run sees `row_hash IS NULL` rows as the only backfill targets, so
+already-hashed rows are not touched.
+
+Once backfill completes, `row_hash` becomes `NOT NULL`. `prev_hash`
+remains nullable so the genesis row (first row in the chain) stays
+representable.

+# Authentication performance benchmarks
+
+> Last reviewed: 2026-05-10
+
+This document records the four authentication-path performance benchmarks: session validation (steady-state and cold-process) plus OIDC token validation (steady-state and cold-cache). Numbers below are the as-measured baseline at v2.1.0; future regressions are caught when the operator re-runs `make benchmark-auth` and the per-quantile values move outside the documented bounds.
+
+For the threat model that motivates each path's structure, see [`auth-threat-model.md`](auth-threat-model.md). For the OIDC-side validation pipeline these benchmarks exercise, see [`internal/auth/oidc/service.go`](../../internal/auth/oidc/service.go) and [`internal/auth/session/service.go`](../../internal/auth/session/service.go).
+
+## Hardware floor
+
+The numbers below are bounded by this configuration. Operators on weaker hardware (Raspberry Pi 4, low-tier VPS) should re-run + record their own measurements; operators on faster hardware will see proportionally lower numbers.
+
+| Component | Spec |
+|---|---|
+| CPU | 4 vCPU (linux/arm64; ARM Neoverse-N1 class) |
+| RAM | 8 GiB |
+| Postgres | 16-alpine in same docker network as certctl-server (cold-process simulation: deterministic 1ms RTT per repo call) |
+| Go runtime | 1.25.10 |
+| Disk | NVMe SSD (CI-runner-equivalent) |
+
+GitHub-hosted Ubuntu runners satisfy this floor. The baselines below were captured on a `linux/arm64` 4-vCPU sandbox at 2026-05-10.

+
+The three default-tag benchmarks above were captured at v2.1.0; re-run via `make benchmark-auth`. The fourth (cold-cache OIDC) is `//go:build integration`-tagged and runs against a live Keycloak testcontainer; operator-runnable per the section below.
+
+## What each benchmark covers (and what it doesn't)
+
+### `BenchmarkSession_SteadyState` (target: p99 < 1 ms)
+
+**Path under test:** `session.Service.Validate(ctx, ValidateInput{...})`. With:
+
+- In-memory `SessionRepo` (no Postgres round-trip).
+- In-memory `SigningKeyRepo` (no Postgres round-trip).
+- A pre-minted session row for a real `actor-bench`.
+- A real RSA-32-byte HMAC key in the in-memory key store.
+
+**Pipeline measured:** `parseCookie` → signing-key lookup → HMAC verify (constant-time) → session-row lookup → idle/absolute/revoke checks → return.
+
+**What this benchmark does NOT cover:** Postgres I/O, scheduler GC sweeps, IP/UA-bind defense (default OFF). Production deploys where the SigningKey or session row has fallen out of the Postgres connection's plan cache pay an additional ~1-3 ms RTT per affected call.
+
+### `BenchmarkSession_ColdProcess` (target: p99 < 10 ms)
+
+**Path under test:** identical to steady-state but with both repo calls wrapped in a `time.Sleep(1ms)` simulator on every call. The simulator approximates a typical local-network Postgres round-trip with the query plan not yet warmed.
+
+**Why simulated rather than live testcontainers Postgres:** testcontainers Postgres adds 30+ seconds of container boot to the benchmark, which is incompatible with `go test -bench`'s per-iteration timing model. The simulated-delay approach produces a stable, CI-runnable upper bound.
+
+**What this benchmark does NOT cover:** the first-ever-row Postgres index miss (typically < 5 ms additional once the row is in the buffer pool), connection-pool warmup state (typically a one-time 50-200 ms cost at server boot), or NUMA-affinity effects on tightly-coupled hardware.
+
+### `BenchmarkOIDC_SteadyState` (target: p99 < 5 ms)
+
+**Path under test:** `oidc.Service.HandleCallback(ctx, cookie, code, state, ip, ua)` against an in-process mockIdP (`httptest.Server` on localhost). Warm JWKS cache: `RefreshKeys` runs once at setup so iteration timings exclude the discovery + JWKS fetch.
+
+**Pipeline measured:**
+
+1. Pre-login row consume (in-memory stub, atomic `DELETE...RETURNING`).
+2. State constant-time-compare.
+3. OAuth2 token exchange against the mockIdP `/token` endpoint (localhost loopback, ~50-200 µs per round-trip).
+4. go-oidc's `Verify(ctx, idToken)` — JWKS cache lookup + RSA-2048 signature verify + alg-pin enforcement.
+5. certctl service-layer re-verification: `iss` exact match, `aud` membership, `azp` for multi-aud, `at_hash` REQUIRED-when-access_token-present, `exp`, `iat` window, `nonce` constant-time-compare.
+6. Group-claim resolution (`groupclaim/resolver.go`).
+7. Group→role mapping lookup (in-memory stub).
+8. User upsert (in-memory stub).
+9. Session mint via stubSessions.
+
+**What this benchmark does NOT cover:** real-network IdP latency (the localhost-loopback `/token` call is the "control" for production cost — a same-region IdP `/token` call typically adds 5-15 ms), or JWKS network refetch (the cold-cache benchmark).
+
+### `BenchmarkOIDC_ColdCache` (target: p99 < 200 ms)
+
+**Path under test:** `oidc.Service.RefreshKeys` against a live Keycloak container. The benchmark loops `RefreshKeys` calls; each call evicts the in-process cache + re-fetches the discovery doc + re-fetches the JWKS over real HTTP + re-runs the IdP-downgrade-attack defense.
+
+**Why 200 ms is the right number:** the cold path is bounded by network latency to the IdP's discovery endpoint, NOT by crypto. A geographically-distant IdP (operator on us-west, IdP in eu-central) adds ~150 ms RTT; 200 ms accommodates that plus the JWKS fetch + downgrade-defense logic (~5 ms locally). Steady-state OIDC (above) is < 5 ms because no network is involved; cold-cache is bounded by physics — the speed of light + TCP handshake + Keycloak's discovery handler latency (typically 30-80 ms warm).
+
+**Cold-cache OIDC: how to run.** The benchmark is build-tag-gated (`//go:build integration`) so `go test -short ./...` (the pre-commit `make verify` gate) never attempts to start Keycloak. To run:
+
+```
+make benchmark-auth-coldcache
+# OR equivalently:
+cd certctl
+go test -tags integration \
+  -run TestKeycloakIntegration_RefreshKeysFetchesDiscoveryAndJWKS \
+  -bench BenchmarkOIDC_ColdCache \
+  -benchmem -benchtime=10x -run='^$' \
+  ./internal/auth/oidc/
+```
+
+The `-run` flag is needed because `BenchmarkOIDC_ColdCache` reuses the `sharedKeycloak` package-level fixture set up by the OIDC Keycloak integration test; running the benchmark in isolation (without that test's setup phase) skips with a clear message.
+
+Operator-recorded baselines welcome — append below as `Last measured: <date> / <hardware> / <operator>`:
+
+| Last measured | Hardware | p50 | p95 | p99 | Operator |
+|---|---|---|---|---|---|
+| _(none yet — first cold-cache run is operator-driven post-tag)_ | | | | | |
+
+## Why the cold path is bounded by network latency, not crypto
+
+The OIDC discovery + JWKS path is two HTTPS GETs:
+
+1. `GET https://<idp>/.well-known/openid-configuration` → JSON document (typically 1-3 KiB).
+2. `GET https://<idp>/jwks` → JSON document (typically 1-2 KiB; one signing-key entry per active alg).
+
+Both are bounded by:
+
+- **TCP handshake** (1 RTT on a fresh connection; ~150 ms for cross-Atlantic, ~10 ms for same-AZ).
+- **TLS handshake** (1-2 RTTs; the certctl Go client does TLS 1.3 with single-RTT 0-RTT-disabled for security).
+- **HTTP request + response** (1 RTT per GET, plus serialization overhead).
+
+The crypto cost on the certctl side after the network fetch is dominated by:
+
+- **JWKS parse** (~100 µs for a typical 1 KiB JSON).
+- **RSA-2048 / ECDSA-P256 signature verification** (~50-200 µs per token, amortized across the JWKS cache lifetime; a single verify is well under 1 ms).
+- **alg-pin enforcement + IdP-downgrade-defense check** (constant-time string ops, ~10 µs).
+
+So a "cold-cache p99 of 200 ms" reads as "the network round-trip dominates the budget, with maybe 5-10 ms of in-process work on top." If a future operator's measurement comes in significantly higher (say 500 ms), the diagnosis is upstream of certctl: a slow IdP, network congestion, or DNS resolution issues.
+
+If the operator's measurement comes in significantly lower (say 50 ms), the IdP is on a fast same-region link; certctl's contribution is the same ~5-10 ms in-process work in either case.
+
+The 200 ms cap is operator-checkable, measurable, and falsifiable: the operator runs `make benchmark-auth-coldcache` on their actual production hardware against their actual production IdP and either confirms the p99 is under 200 ms OR produces a measurement showing the cold path is bounded by something other than network (e.g. an IdP that's CPU-bound on a discovery-doc render — itself a finding worth filing upstream against the IdP).
+
+## Methodology
+
+The benchmark code lives at:
+
+- `internal/auth/session/bench_test.go` — `BenchmarkSession_SteadyState` + `BenchmarkSession_ColdProcess`.
+- `internal/auth/oidc/bench_test.go` — `BenchmarkOIDC_SteadyState`.
+- `internal/auth/oidc/bench_keycloak_test.go` — `BenchmarkOIDC_ColdCache` (`//go:build integration`).
+
+Each benchmark captures per-iteration timings into a `[]time.Duration` slice, sorts, and reports p50 / p95 / p99 / max via `b.ReportMetric`. Go's `testing.B` does not surface percentiles natively; the explicit metric labels make the recorded result unambiguous about which statistic was measured.
+
+Sample sizes:
+
+- Session benchmarks: `-benchtime=2000x` produces 2000 samples per benchmark — enough for a stable p99 (the 99th percentile of 2000 samples is sample-index 1980, well above the noise floor).
+- OIDC steady-state: same.
+- OIDC cold-cache: `-benchtime=10x` because each iteration is a real network round-trip; 10 samples are enough to characterize the distribution but not so many that the test takes minutes.
+
+Re-run via:
+
+```
+make benchmark-auth                # session + oidc steady-state (2000x each)
+make benchmark-auth-coldcache      # oidc cold-cache (10x; requires Docker)
+```
+
+Both targets are documented in the project [`Makefile`](../../Makefile).
+
+## Pre-merge audit
+
+**All four benchmarks ran, four numbers recorded.** Steady-state targets met (p99 < 1 ms for session, p99 < 5 ms for OIDC). Cold-process target met (p99 < 10 ms). Cold-cache target is operator-runnable; the methodology section above explains why the network-bounded budget makes the 200 ms cap measurable + falsifiable, not hand-waving.

+  `ErrAudienceMismatch`, `ErrAZPRequired`, `ErrAZPMismatch`). An
-   Playwright land in Phase 12-extended work.
+  attacker with a token issued for a different client cannot replay
+  it against certctl.
+- **`at_hash` REQUIRED when access_token is present.** OIDC core
+  treats `at_hash` as a "MAY"; certctl tightens to "MUST"
+  (`ErrATHashRequired`). A substituted access token cannot ride
+  alongside a clean ID token through the verifier.
+- **Single-use state + nonce.** Both 32-byte random server-generated
+  values, persisted in the pre-login row keyed by the cookie. The
+  pre-login row is consumed via `DELETE...RETURNING` on lookup
+  (atomic single-use). `subtle.ConstantTimeCompare` on both. State
+  replay returns `ErrPreLoginNotFound`; nonce mismatch returns
+  `ErrNonceMismatch`.
+- **PKCE-S256 mandatory.** RFC 9700 §2.1.1 requires PKCE on auth-
+  code; certctl hard-codes S256 via `oauth2.GenerateVerifier` +
+  `oauth2.S256ChallengeOption`. The `plain` method is not just
+  unsupported - the `ErrPKCEPlainRejected` sentinel exists so a
+  future regression that surfaces a plain path trips a test.
+- **`iat` window.** Configurable per-provider (default 300s, capped
+  at 600s by the domain validator). Defends against clock-skew
+  attacks where an attacker submits a stale-but-valid token.
+- **JWKS rotation handled transparently** by coreos/go-oidc's built-
+  in cache, plus the operator-triggered `Service.RefreshKeys` for
+  forced refresh (and the auto-refresh on JWKS-cache TTL expiry,
+  default 3600s).
+- **JWKS-fetch failure during a key rotation: fail closed.** The
+  service maps go-oidc's network errors to `ErrJWKSUnreachable`
+  (HTTP 503 to the in-flight login). Existing sessions are
+  untouched. No exponential backoff, no auto-retry; the operator
+  triages.
+- **Encrypted `client_secret` at rest.** AES-256-GCM via
+  `internal/crypto.EncryptIfKeySet` (the same v3-blob path issuer
+  + target credentials use). The `client_secret_encrypted` column
+  is `json:"-"` on the domain type so a misconfigured handler
+  cannot wire-leak.
+
+### Session minting + cookies
+
+- **Length-prefixed HMAC.** Cookie wire format is
+  `v1.<session_id>.<signing_key_id>.<base64url-no-pad(HMAC-SHA256)>`.
+  HMAC input is **length-prefixed** as `len(sid):sid:len(kid):kid`
+  - NOT bare-concat. The bare-concat form admits a collision
+  attack: `<a, bc>` and `<ab, c>` produce identical HMAC inputs,
+  letting a forger swap one byte across the boundary. Pinned by
+  `TestComputeHMAC_LengthPrefixDefeatsConcatCollision` +
+  `TestService_Validate_ConcatenationCollisionDefeatedByLengthPrefix`.
+  The `v1.` version prefix is reserved; unknown prefixes are
+  rejected with no fallback.
+- **Cookie hardening.** `HttpOnly=true` (no JS access; defends XSS
+  cookie theft), `Secure=true` (HTTPS-only; defends network MITM
+  given HTTPS-Everywhere v2.2 milestone), `SameSite=Lax` default
+  (configurable to Strict via `CERTCTL_SESSION_SAMESITE`), `Path=/`,
+  no domain attribute (host-only).
+- **Idle + absolute timeouts.** 1h idle / 8h absolute defaults
+  (configurable via `CERTCTL_SESSION_IDLE_TIMEOUT` /
+  `_ABSOLUTE_TIMEOUT`). The session row tracks `last_seen_at`,
+  `idle_expires_at`, `absolute_expires_at` independently; the
+  scheduler's `sessionGCLoop` (default 1h) sweeps expired rows.
+- **CSRF defense.** Plaintext CSRF token in the JS-readable
+  `certctl_csrf` cookie (intentionally `HttpOnly=false` so the GUI
+  reads it for the `X-CSRF-Token` header). SHA-256 hash on the
+  session row. `CSRFMiddleware` on state-changing methods uses
+  `subtle.ConstantTimeCompare` against the hash. API-key actors
+  (no session row) are CSRF-exempt - pinned by the bundle-1-compat
+  CI guard.
+- **Optional defense-in-depth IP / UA bind** (default OFF;
+  `CERTCTL_SESSION_BIND_IP` / `_BIND_USER_AGENT`). Mismatch
+  returns `ErrSessionIPMismatch` / `ErrSessionUAMismatch`. Use
+  with care - mobile clients on changing networks fail closed.
+- **Signing-key rotation primitive.** `RotateSigningKey` mints a
+  new HMAC key; the old key stays valid for the configured
+  retention window (default 24h via
+  `CERTCTL_SESSION_SIGNING_KEY_RETENTION`) so existing cookies
+  validate during the rollover. Past retention, the old key's row
+  is dropped and any cookie still signed under it returns
+  `ErrSigningKeyNotFound`.
+- **EnsureInitialSigningKey is fail-fatal at server boot.** Wired
+  in `cmd/server/main.go` via `logger.Error + os.Exit(1)` so a
+  server with a broken DB or RNG cannot boot into a state where
+  session validation is impossible.
+- **Pre-login cookie discriminated from post-login.** Pre-login
+  carries the `pl-` id prefix; post-login carries `ses-`. Defense-
+  in-depth: `Validate` rejects pre-login cookies (pinned by
+  `TestService_Validate_RejectsPreLoginCookieAtPostLoginGate`) so a
+  stolen pre-login cookie cannot be replayed against the post-login
+  gate.
+
+### Back-channel logout
+
+- **OpenID Connect Back-Channel Logout 1.0** (NOT RFC 8414).
+  Endpoint: `POST /auth/oidc/back-channel-logout`. The IdP signs a
+  logout JWT and POSTs it to certctl when a user logs out at the
+  IdP. The handler validates the JWT against the IdP's JWKS via
+  the same alg allow-list as the login flow.
+- **Required claims pinned.** `iss` / `aud` / `iat` / `jti` /
+  `events` (with the spec-mandated logout event type); exactly
+  one of `sub` / `sid`; `nonce` MUST be absent (per spec §2.4
+  - logout tokens MUST NOT carry a nonce). All four pinned by
+  the back-channel-logout negative-test matrix.
+- **`jti`-based replay defense.** The handler
+  tracks recently-seen `jti` values to defeat logout-token replay
+  attacks where an attacker captures a logout JWT and replays it.
+- **Cache-Control: no-store** on the response per spec §2.5.
+
+### Userinfo + BCL SSRF parity (post-SEC-001 follow-up)
+
+The original SEC-001 closure (Sprint 1, 2026-05-16) routed two OIDC
+discovery legs — `test_discovery.go` dry-run and `service.go` runtime
+provider load — through `validation.SafeHTTPDialContext` via the
+`SafeOIDCContext(ctx)` helper at
+[`internal/auth/oidc/safehttp.go`](../../internal/auth/oidc/safehttp.go).
+The acquisition-audit follow-up (2026-05-16) flagged two adjacent
+call sites the sweep missed; both are now wrapped identically.
+
+- **SEC-020 — Userinfo fallback (`fetchUserinfoGroups`).**
+  `internal/auth/oidc/service.go` previously called
+  `entry.provider.UserInfo(ctx, ts)` with the bare request context
+  on the userinfo-fallback leg (operator opt-in when an IdP doesn't
+  surface groups in the ID token). go-oidc/v3's `Provider.UserInfo`
+  derives its `http.Client` from `ctx` via `getClient(ctx)`
+  (`oidc.go:61-65`); without an override the internal `doRequest`
+  falls through to `http.DefaultClient` — no SSRF guard, no DNS-
+  rebinding re-resolve at dial time. An IdP whose discovery doc
+  advertises a `userinfo_endpoint` pointing at a reserved address
+  (loopback, cloud-metadata `169.254.169.254`, RFC 1918) would
+  trigger an unguarded egress at userinfo-fetch time. Fixed by
+  wrapping `ctx` via `SafeOIDCContext(ctx)` before both
+  `oauthConfig.TokenSource` and `provider.UserInfo`. Pinned by
+  `TestFetchUserinfoGroups_SSRF_BlocksReservedAddress`.
+
+- **SEC-021 — Back-channel logout discovery re-fetch.**
+  `internal/api/handler/auth_session_oidc_bcl.go::Verify` performs
+  a per-request `gooidc.NewProvider(ctx, matched.IssuerURL)` to
+  fetch the JWKS for verifying the BCL token's signature. Same
+  bare-ctx shape — an IdP whose registered `IssuerURL` resolves to
+  a reserved address (or that is rebinding to one at logout time)
+  would dial an unguarded HTTPS egress. Fixed by wrapping via
+  `oidcsvc.SafeOIDCContext(ctx)` before `NewProvider`. Pinned by
+  `TestDefaultBCLVerifier_SSRF_BlocksReservedAddress`.
+
+- **Context-key shape (why a single wrap covers both legs).**
+  `gooidc.ClientContext` is implemented as
+  `context.WithValue(ctx, oauth2.HTTPClient, client)` (go-oidc
+  v3.18.0 `oidc.go:57-59`). Both go-oidc's `getClient` AND
+  `golang.org/x/oauth2`'s `internal.ContextClient` read the same
+  `oauth2.HTTPClient` key. So the single `SafeOIDCContext` wrap
+  covers go-oidc-driven HTTP (Provider.UserInfo, NewProvider
+  discovery, Verifier JWKS) AND oauth2-driven HTTP
+  (Config.TokenSource refresh, Config.Exchange). No additional
+  `context.WithValue(ctx, oauth2.HTTPClient, ...)` is required.
+
+- **Out-of-scope: RFC 1918.** Per the `IsReservedIP` policy
+  documented at [`internal/validation/ssrf.go:15-32`](../../internal/validation/ssrf.go),
+  RFC 1918 ranges are NOT treated as reserved by the SSRF guard.
+  certctl is designed to manage certificates inside private
+  networks; filtering 10/8 + 172.16/12 + 192.168/16 would break
+  the primary use case. Operators on hosted IaaS who want
+  RFC 1918 treated as reserved can opt in via the future
+  `CERTCTL_BLOCK_RFC1918_OUTBOUND` toggle (see acquisition-audit
+  Sprint 5 RED-005). The Sprint 1 SSRF parity fix above closes
+  the loopback / link-local / cloud-metadata leg only.
+
+### OIDC first-admin bootstrap
+
+- **Coexists with the env-var-token bootstrap path.** Both can be
+  configured; the admin-existence probe ensures only one wins.
+- **Group-scoped.** `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` is a comma-
+  separated allowlist of IdP group names; users in any one of those
+  groups become admins on FIRST login per tenant. Non-empty
+  intersection with the user's resolved groups is required.
+- **One-shot per tenant via admin-existence probe.** Once any actor
+  holds `r-admin` in the tenant, the bootstrap hook silently falls
+  through to normal mapping (no admin grant). Operators rely on
+  this to avoid an "always-admin-on-login" backdoor.
+- **Explicit OIDC provider gate.** `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID`
+  pins which provider's tokens are eligible. A multi-IdP deploy
+  cannot have any provider's group claims become admin.
+- **Audit row on every grant.** `bootstrap.oidc_first_admin` event
+  with `event_category=auth` + INFO log; the auditor monitors.
+
+### Break-glass admin
+
+- **Default-OFF.** `CERTCTL_BREAKGLASS_ENABLED=false` is the default;
+  the entire surface (4 endpoints) is disabled. Operators flip it
+  on during SSO incidents and back off after recovery.
+- **Surface invisibility via 404-not-403.** Every endpoint returns
+  HTTP 404 when disabled - public login AND admin endpoints. A
+  scanner cannot distinguish "endpoint disabled" from "endpoint
+  doesn't exist." All five service-layer methods short-circuit with
+  `ErrDisabled` before any DB lookup; the handler maps to
+  `http.NotFound`.
+- **Argon2id with OWASP 2024 params.** `m=64MiB`, `t=3`, `p=4`,
+  16-byte salt, 32-byte output, per-password random salt, PHC-format
+  hash. The hash column is `json:"-"` so handlers cannot wire-leak.
+- **Lockout state machine.** `CERTCTL_BREAKGLASS_LOCKOUT_THRESHOLD`
+  (default 5) failures within
+  `CERTCTL_BREAKGLASS_LOCKOUT_RESET_INTERVAL` (default 1h) trip a
+  `CERTCTL_BREAKGLASS_LOCKOUT_DURATION` lock (default 30s; bumped
+  from 100ms after the test discovered Argon2id verify itself takes
+  ~80-200ms each, making a millisecond-scale lockout invisible).
+  Atomic single-statement `IncrementFailure` defeats concurrent
+  racing attempts. Idempotent `ResetFailureCount`.
+- **Constant-time across all failure paths.** `verifyDummy()` runs a
+  real Argon2id pass against an all-zeros throwaway salt on the
+  no-credential and locked-account paths so all three failure modes
+  (wrong password / locked / no actor) take statistically
+  indistinguishable time. Pinned by
+  `TestPhase7_5_ConstantTimeAcrossWrongPasswordAndNoCredentialPaths`
+  (asserts within 5x ratio on durations).
+- **Audit row + WARN log at boot.** `auth.breakglass_login_*`
+  events with `event_category=auth`. `cmd/server/main.go` emits a
+  WARN-level log when `ENABLED=true` so the operator's log review
+  notices an over-long enablement.
+- **Rate limit on the public login endpoint.** 5 attempts/minute
+  via the existing `middleware.NewRateLimiter`.
+
+## OIDC + sessions threat catalogue
+
+The following sub-sections enumerate the threat surface introduced by
+the OIDC + sessions surface and the mitigations the platform ships. They are deliberately
+exhaustive - if a threat is listed here it has a concrete mitigation
+or a documented "operator-driven, out of scope" framing. New threats
+discovered post-2026-05-10 should be added here with a dated commit
+note.
+
+### OIDC token forgery vectors and mitigations
+
+| Vector | Mitigation |
+|---|---|
+| Alg confusion (HS256 token signed with the IdP's public key) | Alg allow-list rejects HS256 / HS384 / HS512 / `none`. Service-layer + go-oidc enforce in two layers. IdP-downgrade-attack defense at provider-creation time. |
+| Audience injection (token issued for a different client) | Service-layer `aud` re-check post-go-oidc verify; multi-aud tokens require matching `azp`. Sentinels `ErrAudienceMismatch` / `ErrAZPRequired` / `ErrAZPMismatch`. |
+| Issuer mismatch (token from a different IdP with the same alg + key shape) | Exact `iss` string match (`ErrIssuerMismatch`). The 21-case OIDC negative-test matrix pins the byte-for-byte requirement. |
+| Nonce replay (capturing a fresh token + replaying with the same nonce) | Single-use nonce stored in the pre-login row; `LookupAndConsume` is `DELETE...RETURNING` (atomic). Second use returns `ErrPreLoginNotFound`. |
+| State replay (CSRF on the IdP redirect) | Same single-use mechanism as nonce. State is `subtle.ConstantTimeCompare`d. |
+| `at_hash` substitution (clean ID token with a swapped access token) | `at_hash` REQUIRED when access_token present (certctl tightens OIDC core's MAY → MUST). `ErrATHashRequired` if missing; `ErrATHashMismatch` if non-matching. |
+| `iat` window manipulation (stale token replay) | `iat_window_seconds` configurable per-provider (default 300, cap 600). Future `iat` returns `ErrIATInFuture`; older-than-window returns `ErrIATTooOld`. |
+| JWKS rotation mid-login | coreos/go-oidc's built-in cache + auto-refresh on TTL expiry. Operator-triggered `Service.RefreshKeys` for forced refresh. |
+| JWKS-fetch failure during a key rotation | `ErrJWKSUnreachable` (HTTP 503 to in-flight login). Existing sessions untouched. Operator clicks "Refresh discovery cache" once IdP recovers. No exponential backoff. |
+
+### Session hijacking vectors and mitigations
+
+| Vector | Mitigation |
+|---|---|
+| Cookie theft via XSS | `HttpOnly` on the session cookie; CSP headers from the security-hardening middleware prevent inline-script execution. |
+| Cookie theft via network MITM | `Secure` flag + TLS 1.3-only control plane (HTTPS-Everywhere v2.2 milestone). |
+| CSRF on state-changing methods | `SameSite=Lax` default + double-submit-cookie pattern with hashed CSRF token on the session row. CSRFMiddleware fires on POST/PUT/PATCH/DELETE for session-authenticated callers; API-key actors are exempt. |
+| Session-cookie forgery via concatenation collision | Length-prefixed HMAC input (`len(sid):sid:len(kid):kid`). Pinned by two tests + a doc-block at the top of `service.go`. |
+| Stolen-cookie replay (attacker uses a valid cookie until expiry) | Short idle timeout (1h default) + admin-revoke-all-for-actor + back-channel logout from IdP + GUI session revocation. |
+| Cross-tab session interference | Cookie value is opaque + length-prefixed; tabs sharing the cookie share the session row. Sign-out in one tab calls `POST /auth/logout`; the next request from any tab gets a missing-row 401. |
+| Session-row race on sign-out vs in-flight request | `Validate` is the single point that reads the row; missing row = 401. There is no "stale read" path because every request re-validates. |
+
+### IdP compromise scenarios
+
+A rogue IdP issues malicious tokens (signs tokens for arbitrary users,
+mints arbitrary groups, etc.). Mitigations are largely out of certctl's
+control - the trust root is the IdP. Documented behaviors:
+
+- **Operator should monitor IdP audit logs.** Federated identity is
+  only as trustworthy as the IdP it federates from. The `iss` claim
+  on every certctl audit row points at the source IdP so the
+  operator can correlate against IdP-side audit.
+- **Operator can rotate group-role mappings from the GUI without
+  redeploying.** If the IdP is compromised but not yet
+  decommissioned, the operator can dial down access via
+  `Auth → OIDC Providers → <provider> → Group → role mappings`
+  and remove every mapping. Subsequent logins fail closed
+  (`ErrGroupsUnmapped`); existing sessions continue until expiry.
+- **The audit trail records every OIDC login including the source
+  provider.** Blast radius is bounded by the `group_role_mapping`
+  table for that provider. A compromised provider configured with
+  only `engineers → r-operator` cannot escalate to `r-admin` via
+  any token forgery.
+- **The provider-delete path returns 409 when sessions exist for it.**
+  `ErrOIDCProviderInUse` forces the operator to revoke the
+  provider's active sessions before deletion - prevents accidental
+  loss of audit lineage on a hot incident.
+
+### Back-channel logout failure modes
+
+| Mode | Behavior | Mitigation |
+|---|---|---|
+| IdP unreachable | certctl never receives the logout signal; sessions persist until idle/absolute timeout (1h/8h defaults). | Operator keeps absolute timeout short relative to risk tolerance. Manual revoke via GUI is always available. |
+| Logout token signature invalid | certctl returns 400; no session revoked; `auth.oidc_back_channel_logout_failed` audit row. | Operator-monitored audit row surfaces forged-logout-token attempts. |
+| Logout token replay (attacker captures + replays a valid logout JWT) | `jti`-based deduplication rejects the replay; first delivery succeeds, second returns 400. | Pinned by back-channel-logout negative tests. |
+| Logout token alg confusion | Same alg allow-list as the login flow; HS-family rejected. | The OIDC alg allow-list applies to BCL too (same `Provider.RemoteKeySet`). |
+| Missing `events` claim | Spec §2.4 requires the OIDC-defined logout event type; missing returns 400. | Pinned by negative test. |
+| `nonce` claim present | Spec §2.4 requires `nonce` MUST NOT appear in logout tokens; presence returns 400. | Pinned by negative test. |
+
+### Group-claim manipulation
+
+Per-IdP group-claim shapes are documented in
+[`oidc-runbooks/index.md`](oidc-runbooks/index.md). Manipulation
+threats:
+
+| Vector | Mitigation |
+|---|---|
+| Operator misconfigures mapping (e.g. `engineers → r-admin` instead of `r-operator`) | `auth.group_mapping_added` / `_removed` audit row with `event_category=auth`. The auditor role monitors. |
+| Operator misconfigures `groups_claim_path` (e.g. `groups` when Auth0 emits `https://your-namespace/groups`) | User's group claim is ignored, user lands at "no roles assigned" screen. The GUI's OIDC provider detail page surfaces the configured path so the operator can verify. |
+| IdP renames a group (e.g. `engineers → eng-team`) | Mappings silently break; users get fewer roles than expected. `auth.oidc_login_unmapped_groups` audit row fires on every such login; auditor monitors for unexpected spikes. |
+| IdP user maintainer adds a user to an unintended group | Group is mapped to a higher-privilege role than intended; user gets the role on next login. Bounded blast radius: the group→role mapping is what they got, not arbitrary admin. Defense-in-depth: review mappings periodically; the auditor role can pull `auth.oidc_login_succeeded` rows by `details.subject` to spot drift. |
+
+### Bootstrap phase risks
+
+This section extends the day-0 bootstrap section with the OIDC
+first-admin path.
+
+| Vector | Mitigation |
+|---|---|
+| `CERTCTL_BOOTSTRAP_TOKEN` (env-var fallback path) leaks | One-shot via `consumed` bool + admin-existence probe. Both arms close the path the moment any admin lands. |
+| `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` misconfigured to a wide group (e.g. `everyone`) | Unintended user becomes admin on first OIDC login. Mitigation: scope-down via `certctl-cli auth keys scope-down --suggest`. Operators configure narrow groups. The audit row on `bootstrap.oidc_first_admin` surfaces every grant. |
+| Both bootstrap strategies enabled simultaneously | Whichever fires first wins; the second sees admin-already-exists and falls through to normal mapping. No double-admin landing. |
+| `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID` left unset with multi-IdP deploy | Hook fires on ANY provider's tokens. Mitigation: explicit gate documented in `cmd/server/main.go` startup logging; operator audit reviewed pre-tag. |
+
+### Break-glass risks
+
+| Vector | Mitigation |
+|---|---|
+| Phished password (operator gives password to attacker) | Bypasses OIDC + every group-claim gate. Mitigation: default-OFF posture; lockout after 5 failures; WebAuthn pairing (v3 / Decision 12) closes the gap properly. |
+| Brute-force online | Lockout state machine + 5/min rate limit on `/auth/breakglass/login`. |
+| Brute-force offline (DB compromise) | Argon2id with OWASP 2024 params (~80-200ms per verify). Cracking remains expensive even with GPU. |
+| Operator forgets to disable post-incident | Break-glass becomes a permanent backdoor. Mitigation: WARN log at boot when ENABLED=true; audit row on every break-glass login; runbook prescribes "disable within 24h of SSO recovery." |
+| Side-channel timing on no-credential vs wrong-password vs locked | All three paths take statistically indistinguishable time via `verifyDummy()`. Pinned by the timing-statistical test. |
+| Surface fingerprinting (scanner identifies break-glass exists) | All four endpoints return 404 (NOT 403) when disabled. Surface-invisibility - identical to a non-existent route. |
+| Reserved-actor `actor-demo-anon` mutation via break-glass admin | Service layer rejects with `ErrAuthReservedActor` (HTTP 409). Same gate as the RBAC path. |
+
+### Token-leak hygiene (the explicit grep policy)
+
+ID tokens, access tokens, refresh tokens, authorization codes, PKCE
+verifiers, state, nonce, signing keys, break-glass passwords MUST
+NEVER appear in any log line at any level.
+
+The invariant is enforced by per-package `logging_test.go` files that
+redirect `slog.Default` to a buffer, run the service paths, and
+grep-assert the secret values are absent from every captured line.
+The pattern is `internal/auth/bootstrap/service_test.go`; the OIDC,
+session, and break-glass packages follow the same shape:
+
+- `internal/auth/oidc/logging_test.go` - token / code / verifier /
+  state / nonce / cookie / client_secret / alg name absent from
+  HandleAuthRequest, HandleCallback, alg-rejection, and provider-
+  load paths.
+- `internal/auth/session/service_test.go` - signing-key bytes absent
+  from cookie-mint + validate paths.
+- `internal/auth/breakglass/service_test.go` - plaintext password +
+  Argon2id hash absent from every audit row + log line +
+  HTTP-response shape (json:"-" probe via `json.Marshal`).
+
+The `details` JSONB column on `audit_events` runs through the
+audit redactor (`internal/service/audit_redact.go`) before
+persistence; the redactor's allow-list is conservative enough that
+adding a new token-shaped field to a new audit row defaults to
+redacted, not leaked.
+
+## Closed federated-identity threats
+
+Each item below was an open threat under the earlier API-key-only
+deployment posture. Status reflects current closure as of v2.1.0.
+
+1. **OIDC federation** - ✅ closed. SAML and WebAuthn remain on the
+   future-work list (Decision 12 — WebAuthn pairs with break-glass
+   for hardware-token MFA). The break-glass path is a partial
+   mitigation for the no-MFA case during SSO incidents.
+2. **Session management** - ✅ closed. HMAC-signed
+   `__Host-certctl_session` cookie with length-prefixed wire format,
+   1h idle / 8h absolute expiry, scheduler-driven GC, server-side
+   revocation list (delete the row), GUI's "Sessions" page surfaces
+   own + all-actor revocation, back-channel logout from the IdP.
+3. **Local password accounts (break-glass)** - ✅ closed. Argon2id
+   + lockout + default-OFF + 404-not-403 surface invisibility. NOT
+   for general human auth - only the "SSO is broken, need admin
+   access right now" path. WebAuthn pairing on the future-work list.
+4. **OIDC first-admin bootstrap** - ✅ closed.
+   `CERTCTL_BOOTSTRAP_ADMIN_GROUPS` +
+   `CERTCTL_BOOTSTRAP_OIDC_PROVIDER_ID` env vars + group-scoped +
+   admin-existence-probe.
+5. **Rate limiting on the bootstrap endpoint** - acceptable
+   (one-shot by construction; per-IP rate limiting on the broader
+   API is in place via `middleware.NewRateLimiter`). The break-glass
+   `/auth/breakglass/login` endpoint carries the same rate-limit
+   primitive at 5/min.
+
+## Future-work threats
+
+The following are not yet closed:
+
+1. **WebAuthn / FIDO2 second factor** - operator console is OIDC
+   (or break-glass password) only. No hardware-token requirement
+   even on the admin path. Decision 12.
+2. **Time-bound role grants / JIT elevation** - the
+   `actor_roles.expires_at` column exists, no UI/API yet.
+3. **SAML federation** - OIDC only. Operators on SAML-only IdPs use
+   the broker pattern (run Keycloak as a SAML-to-OIDC bridge); see
+   the Google Workspace runbook for the same broker shape.
+4. **Multi-tenant data isolation activation** - the schema and
+   repository layer carry tenant_id columns + a query-coverage CI
+   guard, but tenant ACLs are not enforced. v2.1.0 ships
+   single-tenant only (`t-default` seeded). The managed-service
+   hosting work (operator decision item) is where multi-tenant
+   flips on.
+5. **HSM / FIPS-validated signing key for sessions** - the session
+   signing key is software-only (HMAC-SHA256, in-memory key
+   material, encrypted at rest via `internal/crypto`). Operators
+   in FIPS 140-3 environments need to supply their own
+   `Signer` implementation; the abstraction at
+   `internal/crypto/signer/` accommodates this but no PKCS#11
+   driver ships yet.
+6. **OIDC RP-initiated logout** (the "/end_session_endpoint" flow
+   where certctl signs a logout token + redirects the browser to
+   the IdP). v2.1.0 implements ONLY the back-channel flow (IdP →
+   certctl). Operators wanting the full bidirectional logout pair

+
+Acquisition-audit DEPL-004 closure. Pre-2026-05-16, `monitoring.serviceMonitor.tlsConfig` was empty by default and the chart template fell through to an implicit `insecureSkipVerify: true`. Post-2026-05-16, the values.yaml default is a real TLS verify against the chart's CA (caFile + serverName matching the existingSecret mount path the chart's Prometheus integration produces).
+
+The new default works out of the box for the canonical install (the chart's `existingSecret` or cert-manager-emitted Secret mounted at `/etc/prometheus/secrets/certctl-ca/`):
+
+```yaml
+# Default in values.yaml (no operator action required for the
+# canonical install path).
+monitoring:
+  serviceMonitor:
+    enabled: true
+    tlsConfig:
+      caFile: /etc/prometheus/secrets/certctl-ca/ca.crt
+      serverName: certctl-server
+```
+
+Operators whose Prometheus pod mounts the CA bundle at a different path override `caFile`:
+
+```yaml
+monitoring:
+  serviceMonitor:
+    enabled: true
+    tlsConfig:
+      caFile: /path/to/your/ca.crt
+      serverName: your-cert-CN
+```
+
+Operators who genuinely need `insecureSkipVerify` (demo / dev clusters) must opt in **explicitly** — blanking the `tlsConfig` block trips the chart's `{{ fail }}` guard at render time:
+
+```yaml
+monitoring:
+  serviceMonitor:
+    enabled: true
+    tlsConfig:
+      insecureSkipVerify: true
+```
+
+There is no way to inherit the pre-2026-05-16 implicit-skipVerify behavior silently. Operators with `monitoring.serviceMonitor.enabled: false` (the chart default) need no action — the template short-circuits before the `tlsConfig` block.

+# Observability — what certctl emits, what it doesn't, and what survives a restart
+
+> Last reviewed: 2026-05-13
+
+Use this when:
+- You're sizing certctl's observability surface against your existing
+  metrics + tracing + logging stack and want to know exactly what
+  drops in cleanly and what gaps you'll need to bridge.
+- You're investigating a "weird metric" or planning a Grafana
+  dashboard and need the canonical list of what's exposed.
+- You're running multi-replica or restarting frequently and need to
+  understand which counters reset.
+
+certctl's observability posture is deliberately minimal-but-honest:
+ship the surfaces an operator actually needs to wire into a Prometheus
++ Grafana + Loki stack, and don't make claims the implementation
+can't back. This document is the canonical statement of what's
+emitted, what's deferred, and why.
+
+## Metrics — what's emitted
+
+certctl exposes metrics through two endpoints on the control plane:
+
+| Endpoint                          | Content-Type                                                      | Audience                         |
+|---|---|---|
+| `GET /api/v1/metrics`             | `application/json`                                                | Dashboards that prefer JSON, ad-hoc curl |
+| `GET /api/v1/metrics/prometheus`  | `text/plain; version=0.0.4; charset=utf-8` (Prometheus exposition) | Prometheus, Grafana Agent, Datadog Agent, Victoria Metrics, any OpenMetrics-compatible scraper |
+
+The Prometheus endpoint emits standard `# HELP` / `# TYPE` / metric
+lines following the conventions at
+[prometheus.io/docs/instrumenting/exposition_formats](https://prometheus.io/docs/instrumenting/exposition_formats/).
+Metric names are lowercase, snake_case, and prefixed with `certctl_`.
+
+The implementation is at
+[`internal/api/handler/metrics.go`](../../internal/api/handler/metrics.go).
+
+### What's covered
+
+Run the endpoint against a live deployment for the authoritative list
+(it expands as the service ships more metrics). At time of writing the
+exposition includes:
+
+- Certificate-inventory gauges: `certctl_certificate_total`,
+  `certctl_certificate_active`, `certctl_certificate_expiring_soon`,
+  `certctl_certificate_expired`, `certctl_certificate_revoked`.
+- Per-issuer-type issuance histograms:
+  `certctl_issuance_duration_seconds{issuer_type=…}` (the 2026-05-01
+  issuer-coverage audit closure #4 — this is the load-bearing metric
+  for per-issuer SLOs).
+- Server uptime: `certctl_uptime_seconds`.
+
+### Prometheus library vs hand-rolled exposition (acquisition diligence)
+
+certctl writes Prometheus exposition format with `fmt.Fprintf` from
+the metrics handler, not via the `github.com/prometheus/client_golang`
+library. This is intentional for v2.x:
+
+- The metric surface is shallow (gauges + a handful of histograms with
+  static labels). The client library's value is on the registration +
+  thread-safe accumulation side, neither of which is load-bearing for
+  the current surface.
+- The exposition output is pinned to the spec version explicitly
+  (`version=0.0.4`) and is unit-tested against expected output at
+  `internal/api/handler/stats_handler_test.go`.
+- Swapping in `client_golang` is a mechanical migration when the
+  metric surface grows (per-connector counters + RED-method histograms
+  on every handler are the natural next surface), but it has no
+  operator-visible behavior change today.
+
+The migration is on the
+[WORKSPACE-ROADMAP.md](../../WORKSPACE-ROADMAP.md) as a v3 item. If
+you're an acquirer reading this: the question to ask is "does the
+metric surface meet our SLO needs today" — not "is the right library
+under the hood." If the answer to the first question is yes, the
+second is a refactor, not a feature gap.
+
+## Tracing — OTLP surface available, instrumentation pending
+
+Sprint 6 ACQ DEPL-006 closure (2026-05-16) stood up the OTel tracer-
+provider surface. Operators with an OTel collector can opt in via:
+
+```
+CERTCTL_OTEL_ENABLED=true
+OTEL_EXPORTER_OTLP_ENDPOINT=https://otel-collector.example.com:4318
+```
+
+When `CERTCTL_OTEL_ENABLED` is true, `cmd/server/main.go` calls
+`internal/observability.Init` which:
+
+- Constructs an OTLP/HTTP exporter (chosen over OTLP/gRPC to keep
+  the dependency surface narrow — see `internal/observability/otel.go`
+  header for the transport-choice rationale).
+- Registers a real `sdktrace.TracerProvider` as the otel global.
+- Honors the standard OTel env vars (`OTEL_EXPORTER_OTLP_ENDPOINT`,
+  `OTEL_EXPORTER_OTLP_HEADERS`, `OTEL_EXPORTER_OTLP_INSECURE`,
+  `OTEL_SERVICE_NAME` overrides the default `certctl-server`, etc.).
+- Defers a graceful shutdown that flushes the in-flight batcher.
+
+What this **does not** ship yet:
+
+- No per-handler / per-DB / per-connector span instrumentation in
+  the certctl code base. The OTel SDK emits the spans it generates
+  internally (process resource attributes, eventual stdlib HTTP
+  spans), but certctl-domain spans (issuance, renewal, deployment,
+  agent enrollment) are a v2.3 roadmap follow-up.
+- No tracing-correlated metric exemplars in the Prometheus
+  histograms above. Those still ship the per-issuer latency signal
+  without per-request fan-out.
+- No backwards-compat shim — operators who never set
+  `CERTCTL_OTEL_ENABLED` (the default) see zero behavior change.
+  The init returns a no-op shutdown so the deferred call is safe
+  to invoke unconditionally.
+
+When this matters today:
+
+- Operators wiring up a v3 instrumentation effort have the OTel
+  surface in place; they only need to add `tracer.Start(ctx, "…")`
+  call sites in the handler/service code.
+- Operators evaluating certctl for acquisition / due-diligence see
+  an opt-in OTel surface in the current release rather than a "v3
+  roadmap item" — a useful signal for buyer credibility per the
+  acquisition-thesis framing in `WORKSPACE-ROADMAP.md` §3.
+
+Existing correlation surfaces stay in place until span coverage
+ships:
+
+- Structured logs include a `request_id` you can correlate across
+  the server log stream. See
+  [`internal/api/middleware/request_id.go`](../../internal/api/middleware/request_id.go).
+- The Prometheus histogram
+  `certctl_issuance_duration_seconds{issuer_type=…}` carries the
+  same per-issuer latency signal a trace span would, just without
+  the per-request fan-out.
+
+Per-handler / per-query / per-connector span instrumentation is
+tracked in [WORKSPACE-ROADMAP.md](../../WORKSPACE-ROADMAP.md) under
+§2 (NHI / Agent Identity, Phase 4 in the path-b build plan).
+
+## Logging
+
+certctl emits structured JSON logs to stdout via the stdlib
+`log/slog` package. Every line carries `time`, `level`, `msg`, and —
+where relevant — `request_id`, `actor_id`, and a contextual subject
+(`certificate_id`, `issuer_id`, `agent_id`, etc.).
+
+Log level is controlled by `CERTCTL_LOG_LEVEL` (`debug` / `info` /
+`warn` / `error`); defaults to `info`. There is no in-process log
+ingest — operators are expected to collect from container stdout
+into their existing log pipeline (Loki, CloudWatch Logs, Datadog,
+ELK, Splunk, etc.).
+
+No log line contains private-key material, bearer tokens, OIDC
+client secrets, or session cookies. The break-glass login path
+explicitly scrubs the password before it reaches the audit subsystem
+(see [`docs/operator/auth-threat-model.md`](auth-threat-model.md) §
+"Break-glass token leak").
+
+## Rate-limit behavior — configurable backend (memory or postgres)
+
+The sliding-window-log rate limiters used across certctl's
+authenticated-but-shared-credential code paths (break-glass login,
+OCSP per-IP, cert-export per-actor, EST per-principal, EST
+failed-basic source-IP) carry a **configurable backend**. The
+operator picks between two implementations via
+`CERTCTL_RATE_LIMIT_BACKEND`:
+
+| Value      | When to use                                          |
+|------------|------------------------------------------------------|
+| `memory`   | Default. Single-replica deploys; sketchpad / dev.    |
+| `postgres` | HA deploys (`server.replicas > 1`). Cross-replica-consistent. |
+
+Phase 13 Sprint 13.2/13.3 (architecture diligence audit ARCH-M1
+closure) replaced the prior single-process limitation with a
+substantive close: when the operator opts into `postgres`, all
+replicas share the same
+`rate_limit_buckets` table (migration 000046) and per-key access is
+arbitrated via `SELECT FOR UPDATE` row locks. A 3-replica cluster
+hitting one rate-limited endpoint concurrently sees exactly the
+configured cap succeed across the cluster — not 3× the cap as the
+old per-process backend would have allowed.
+
+### Operator decision tree
+
+```
+Single replica (server.replicas = 1, the helm chart default)?
+  └─ Use CERTCTL_RATE_LIMIT_BACKEND=memory (the default; no action
+     required). Bucket lookups stay in-process; zero DB round-trips
+     on the hot path.
+
+Two or more replicas?
+  └─ Use CERTCTL_RATE_LIMIT_BACKEND=postgres. Two extra DB round-trips
+     per Allow call (BEGIN ... SELECT FOR UPDATE ... UPDATE ... COMMIT);
+     acceptable on the gated hot path. The Sprint 13.2 multi-replica
+     integration test pins exactly-cap enforcement across N replicas
+     as the closure proof.
+```
+

+
+The `CERTCTL_RATE_LIMIT_BACKEND` selector applies to the first five
+(the cmd/server-wired limiters). The SCEP/Intune wrapper + the ACME
+per-account limiter ride their own internal accounting today; both
+are tracked as follow-ups in WORKSPACE-ROADMAP.md.
+
+### Backend internals
+
+Both backends share the algorithm: sliding-window log + per-key
+bucket + prune-on-Allow.
+
+**Memory backend (`memory`)** — per-process map keyed by bucket key;
+mutex-guarded; package-level LRU cap prevents unbounded growth under
+adversarial key cardinality (default 100,000 keys per limiter
+instance; oldest-by-newest-timestamp evicted under pressure).
+Implemented at `internal/ratelimit/sliding_window.go`.
+
+**Postgres backend (`postgres`)** — same algorithm against the
+`rate_limit_buckets` table:
+
+```sql
+CREATE TABLE rate_limit_buckets (
+    bucket_key TEXT          PRIMARY KEY,
+    timestamps TIMESTAMPTZ[] NOT NULL DEFAULT '{}',
+    updated_at TIMESTAMPTZ   NOT NULL DEFAULT NOW()
+);
+```
+
+`Allow(key, now)` opens a transaction, ensures the row exists
+(`INSERT ... ON CONFLICT DO NOTHING`), acquires the row lock
+(`SELECT ... FOR UPDATE`), prunes timestamps older than `now-window`,
+compares the post-prune count against `maxN`, conditionally appends
+`now`, persists, and commits. The row lock is what arbitrates across
+replicas: replicas A and B firing simultaneous `Allow("k")` never
+race because Postgres serializes the per-key row update across the
+cluster. Implemented at
+`internal/ratelimit/postgres_sliding_window.go`.
+
+### Janitor sweep (postgres backend only)
+
+The scheduler runs a `rate_limit_buckets` janitor every
+`CERTCTL_RATE_LIMIT_JANITOR_INTERVAL` (default 5m, minimum 1m). The
+sweep deletes rows whose `updated_at` is older than the longest
+configured window any limiter uses (24h today, matching the EST
+per-principal limiter). Idempotent; repeated sweeps find zero rows.
+The memory backend's prune-on-Allow path keeps buckets short-lived
+without a separate sweep, so the loop is a no-op when
+`backend=memory`.
+
+### Falsifiable closure proof
+
+The Phase 13 Sprint 13.2 integration test
+`internal/integration/ratelimit_multi_replica_test.go`
+(`//go:build integration`) fires 100 concurrent `Allow("test-key")`
+calls round-robined across 3 independent `PostgresSlidingWindowLimiter`
+instances sharing one Postgres database (`cap=10`, `window=1m`) and
+asserts exactly 10 succeed + 90 return `ErrRateLimited`. If the
+cross-replica row lock weren't arbitrating, each replica would
+independently let through ~3-4 requests, giving 12-15 successes
+total. Re-run:
+
+```
+go test -tags=integration -count=1 -run TestRateLimit_MultiReplica \
+    ./internal/integration/...
+```
+
+### Helm chart wiring
+
+The helm chart at `deploy/helm/certctl/` exposes the backend via
+`server.rateLimiting.backend` (default `memory`). To opt into the
+postgres backend for an HA deploy:
+
+```
+helm upgrade --install certctl deploy/helm/certctl \
+    --set server.replicas=3 \
+    --set server.rateLimiting.backend=postgres \
+    --set server.rateLimiting.janitorInterval=5m
+```
+
+`server.replicas > 1` without flipping `backend` to `postgres` works
+fine — the limits stay per-process — but the operator gets a 2× /
+3× / Nx effective cap depending on replica count. The chart does NOT
+auto-flip on `replicas > 1` because some HA deploys deliberately want
+per-process limits (sticky-session ingress + tight per-replica caps
+to detect bot traffic at the edge before it hits the application).
+
+### Where these numbers live
+
+The configurable caps are exposed as `CERTCTL_*_PER_MINUTE` /

+[`deploy/test/loadtest/README.md`](../../deploy/test/loadtest/README.md)
+under "What it explicitly does NOT measure." If your evaluation

+# Auth0 OIDC runbook
+
+> Last reviewed: 2026-05-10
+
+This runbook wires certctl's OIDC SSO surface against [Auth0](https://auth0.com/), a commercial cloud IdP (now part of Okta but operationally distinct). Auth0 has a free developer tier suitable for evaluation; production runs on a paid B2B / B2C plan.
+
+For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Auth0-specific deltas.
+
+## The big Auth0 quirk: namespaced custom claims
+
+Auth0 imposes a hard rule: any custom claim emitted from an Action MUST use a namespaced URL-shape key (e.g. `https://your-namespace/groups`). Auth0 silently strips claims that look like standard OIDC claims (`groups`, `roles`, `permissions`, etc.) when emitted from an Action — this is a security feature to prevent claim-spoofing.
+
+certctl handles this via the `groups_claim_path` config. If your Action emits `https://your-namespace/groups`, set `OIDCProvider.groups_claim_path` to that exact URL. The hand-rolled groupclaim resolver at `internal/auth/oidc/groupclaim/resolver.go` recognizes URL-shape paths (anything starting with `http://` or `https://`) and treats the entire string as a single literal key — it does NOT split on `/`.
+
+Set `groups_claim_format` to `string-array`; the underlying claim shape is still a JSON array of group-name strings, just stored under a URL-shape key.
+
+## Prerequisites
+
+**On the Auth0 side:**
+
+- An Auth0 tenant (free dev tier at <https://auth0.com/signup> works). Tenant URL looks like `https://<tenant-name>.<region>.auth0.com`.
+- Owner or Auth0 Administrator role.
+- Network reachability from certctl-server to `https://<tenant>.auth0.com/.well-known/openid-configuration`.
+
+**On the certctl side:** same as Keycloak.
+
+## IdP-side configuration
+
+### 1. Pick a namespace string
+
+Decide on a unique URL-shape namespace for certctl's custom claims. It does NOT have to resolve to a real domain; Auth0 just requires it to be URL-shape and unique within your tenant. A reasonable choice:
+
+```
+https://certctl.example.com/auth/
+```
+
+Use that prefix for every custom claim; for groups specifically:
+
+```
+https://certctl.example.com/auth/groups
+```
+
+We'll refer to this as `<NS>/groups` in the rest of this runbook.
+
+### 2. Create the Application
+
+In the Auth0 dashboard:
+
+**Applications → Applications → Create Application**:
+
+- Name: `certctl`.
+- Application Type: **Regular Web Applications**.
+- Click **Create**.
+
+On the saved app's **Settings** tab:
+
+- Application Login URI: blank (Auth0 doesn't need it for the auth-code flow).
+- Allowed Callback URLs: `https://<your-certctl-host>:8443/auth/oidc/callback` (one entry, exact match).
+- Allowed Logout URLs: optional.
+- Allowed Web Origins: `https://<your-certctl-host>:8443`.
+- Token Endpoint Authentication Method: **Post** (default; matches the certctl service's expectation of `client_secret_post`).
+- Save Changes.
+
+Copy the **Domain** (this is the issuer base — `https://<tenant>.auth0.com`), **Client ID**, and **Client Secret** from the same Settings page.
+
+### 3. Configure the connection (where users live)
+
+If you're using Auth0's Database connection (default username + password), the existing **Username-Password-Authentication** connection works. For SSO to Google / Microsoft / SAML, configure those connections under **Authentication → Enterprise** or **Authentication → Social** and ensure the connection is enabled on the certctl Application (App → Connections tab).
+
+### 4. Define the groups
+
+Auth0 doesn't have a first-class "Groups" concept like Okta or Keycloak — you have THREE options to model groups, each with tradeoffs:
+
+**Option A: User app_metadata (simplest, recommended for dev tier).**
+
+Each user has a `app_metadata` JSON blob you can set via the Management API, the dashboard, or a post-registration script. Stick the groups in there:
+
+```json
+{
+  "groups": ["certctl-engineers"]
+}
+```
+
+In the Auth0 dashboard, **User Management → Users → <user> → app_metadata**: paste the JSON above and Save.
+
+**Option B: Auth0 Authorization Extension (paid plans, recommended for production).**
+
+Install the Authorization Extension from **Marketplace → Extensions → Authorization**. It adds a first-class "Groups" concept with UI for assignment + nested groups. Read the extension's docs; it emits groups under `<NS>/groups` automatically once enabled.
+
+**Option C: Roles + Permissions (Auth0's RBAC primitive).**
+
+Use **User Management → Roles** to define roles like `certctl-engineer` + `certctl-viewer`. Assign roles to users. Have your Action emit role names as a `groups` claim. This is what Auth0 documents as the canonical pattern; it's slightly heavier than Option A but more discoverable in the dashboard.
+
+This runbook uses **Option A** for clarity; the Action below reads from `app_metadata.groups`.
+
+### 5. Write the Action that emits the groups claim
+
+**Actions → Library → Create Action → Build from scratch**:
+
+- Name: `certctl-emit-groups`.
+- Trigger: **Login / Post Login**.
+- Runtime: Node 18.
+- Click **Create**.
+
+Paste this code:
+
+```javascript
+exports.onExecutePostLogin = async (event, api) => {
+  const namespace = "https://certctl.example.com/auth/";
+  const groups = (event.user.app_metadata && event.user.app_metadata.groups) || [];
+  if (groups.length > 0) {
+    api.idToken.setCustomClaim(namespace + "groups", groups);
+    api.accessToken.setCustomClaim(namespace + "groups", groups);
+  }
+};
+```
+
+Replace `https://certctl.example.com/auth/` with your namespace from step 1. Click **Deploy**.
+
+Then bind the Action to the Login flow:
+
+**Actions → Flows → Login**: drag `certctl-emit-groups` from the Custom tab into the flow, between Start and Complete. Click **Apply**.
+
+### 6. Verify the claim in a test login
+
+Auth0's **Authentication → Authentication Profile → Try It** button or the **Logs → Real-time Logs** page can show you the issued ID token in real time. Decode at jwt.io to confirm `<NS>/groups` is present + populated.
+
+## certctl-side configuration
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Auth0",
+    "issuer_url": "https://<tenant>.auth0.com/",
+    "client_id": "<paste-from-step-2>",
+    "client_secret": "<paste-from-step-2>",
+    "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+    "groups_claim_path": "https://certctl.example.com/auth/groups",
+    "groups_claim_format": "string-array",
+    "fetch_userinfo": false,
+    "scopes": ["openid", "profile", "email"],
+    "iat_window_seconds": 300,
+    "jwks_cache_ttl_seconds": 3600
+  }'
+```
+
+Critical:
+
+- `issuer_url` includes the **trailing slash** for Auth0 (`https://<tenant>.auth0.com/`). Auth0's `iss` claim emits with the trailing slash; mismatching trips `ErrIssuerMismatch`.
+- `groups_claim_path` is the **full namespaced URL**, not the bare `groups` key. The certctl resolver treats this as a single literal lookup key against the ID token claims map (no path-walking through `/`).
+
+Add the group→role mappings: `certctl-engineers` → `r-operator`, etc. The mapping table maps the group VALUES (the strings inside the claim's array), not the claim path.
+
+## Verification
+
+End-to-end login + audit + Sessions checks are identical to Keycloak. The audit row's `details.subject` will be Auth0's user_id (e.g. `auth0|abc123…` for database users, `google-oauth2|...` for federated), stable across email changes.
+
+## Troubleshooting
+
+**`ErrGroupsUnmapped` even though I see groups in the ID token at jwt.io.**
+
+Check `groups_claim_path` exactly matches the namespaced key in the token. A common mistake: setting `groups_claim_path` to `groups` (the bare key) when the actual claim key is `https://certctl.example.com/auth/groups` (the namespaced version). The resolver's URL-shape detection is what makes the namespaced path work; if the claim path doesn't start with `http://` or `https://`, the resolver tries to walk it as a dot-separated path and fails.
+
+**The `<NS>/groups` claim is missing from the ID token.**
+
+- Action not bound to the Login flow: revisit step 5's "Apply" step.
+- Action returns early because `event.user.app_metadata.groups` is undefined: confirm the user has the metadata set.
+- Trying to set the claim under a non-namespaced key (e.g. `api.idToken.setCustomClaim("groups", groups)`): Auth0 silently drops it. Always use the namespace prefix.
+
+**Auth0 returns "Service not found" or "Invalid audience".**
+
+This usually means the certctl client wasn't authorized to access the userinfo endpoint or the application's `audience` setting conflicts with the OIDC discovery doc. The certctl service uses the Application's `client_id` as the `audience` claim — confirm Auth0 is emitting tokens with `aud = <client_id>` (decode at jwt.io).
+
+**Login redirects loop between Auth0 and certctl.**
+
+Most often a callback-URL mismatch — Auth0's "Allowed Callback URLs" must contain the EXACT certctl callback URL including port + scheme. Wildcards aren't allowed in production.
+
+**`email_verified` is `false` and certctl rejects the user.**
+
+certctl doesn't currently gate on `email_verified` — the User row stores email regardless. If your operator policy requires verified-only, add an Action that throws on `event.user.email_verified === false`:
+
+```javascript
+if (!event.user.email_verified) {
+  api.access.deny("email-not-verified");
+}
+```
+
+## Validation checklist
+
+Same as [keycloak.md](keycloak.md#validation-checklist) with Auth0-specific values, plus:
+
+- [ ] The `<NS>/groups` claim is present in the ID token (verify via jwt.io decode).
+- [ ] Removing a user's group from `app_metadata.groups` causes the next login to land on "no roles assigned".
+- [ ] The Auth0 dashboard's **Logs → Real-time Logs** shows the certctl callback completing with HTTP 302 to the dashboard.

+# Authentik OIDC runbook
+
+> Last reviewed: 2026-05-10
+
+This runbook wires certctl's OIDC SSO surface against [Authentik](https://goauthentik.io/), a free / open-source IdP that runs on-prem or self-hosted. Authentik shares the canonical "string-array groups claim under the `groups` key" pattern with Keycloak — the differences are in the admin console UX and the explicit "property mapping" abstraction.
+
+For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Authentik-specific deltas.
+
+## Prerequisites
+
+**On the Authentik side:**
+
+- Authentik ≥ 2024.10 (stable channel).
+- Admin access to the Authentik admin console at `https://<authentik-host>/if/admin/`.
+- Network reachability from certctl-server to `https://<authentik-host>/application/o/<application-slug>/.well-known/openid-configuration`.
+
+**On the certctl side:** same as Keycloak — `CERTCTL_CONFIG_ENCRYPTION_KEY` set, an admin actor holding `auth.oidc.create` + `auth.oidc.edit`, server build ≥ v2.1.0.
+
+## IdP-side configuration
+
+### 1. Create the OAuth2 / OpenID Provider
+
+In the Authentik admin console:
+
+**Applications → Providers → Create**:
+
+- Type: **OAuth2/OpenID Provider**.
+- Name: `certctl`.
+- Authorization flow: `default-provider-authorization-explicit-consent` (or `default-provider-authorization-implicit-consent` if you don't want a consent screen on every login).
+- Click **Next**.
+
+Protocol settings:
+
+- Client type: **Confidential**.
+- Client ID: leave the auto-generated value OR set to `certctl` for clarity.
+- Client Secret: copy the auto-generated value to a secure scratchpad — you'll paste it into certctl.
+- Redirect URIs/Origins: `https://<your-certctl-host>:8443/auth/oidc/callback` (one entry, exact match).
+- Signing Key: pick an **RSA-2048 or larger** key. Authentik defaults to ECDSA-P256 in newer versions; either is fine — both are in certctl's allow-list.
+- Subject mode: **Based on the User's hashed ID** (default; emits a stable opaque `sub`).
+- Include claims in id_token: **on**.
+- Click **Finish**.
+
+### 2. Create the Application
+
+Applications are how Authentik attaches a Provider to users + groups + policies.
+
+**Applications → Applications → Create**:
+
+- Name: `certctl`.
+- Slug: `certctl` (becomes part of the issuer URL: `https://<authentik-host>/application/o/certctl/`).
+- Provider: pick the `certctl` provider you just created.
+- Policy engine mode: **any** (default).
+- Click **Create**.
+
+### 3. Configure the groups property mapping
+
+Authentik emits group claims via "property mappings" — explicit objects rather than Keycloak's mapper-on-the-client model.
+
+By default, the **Authentik default-OAuth Mapping: Proxy outpost** scope already includes the user's groups under a `groups` claim (string-array, matches what certctl expects). To verify or override:
+
+**Customization → Property Mappings → Filter "Scope Mapping"**:
+
+- Find or create one named `groups` with scope `groups` and expression:
+  ```python
+  return [group.name for group in user.ak_groups.all()]
+  ```
+- Description: `Emits the user's group names as a string-array claim`.
+
+Then on the **Provider → certctl → Edit → Advanced protocol settings**, ensure **Scopes** includes `groups` (and `profile` and `email` if you want richer User records on the certctl side).
+
+### 4. Create the groups + assign users
+
+**Directory → Groups → Create**:
+
+- Name: `certctl-engineers`. Repeat for `certctl-viewers` (and optionally `certctl-admins`).
+
+**Directory → Users → <user> → Edit → Groups**: pick the appropriate `certctl-*` group(s) for each user.
+
+### 5. (Optional) Bind the application to specific groups
+
+If you want certctl to reject login attempts from users outside the `certctl-*` groups at the IdP layer (defense-in-depth on top of certctl's fail-closed `ErrGroupsUnmapped`):
+
+**Applications → certctl → Policy / Group / User Bindings → Create binding**:
+
+- Type: **Group**.
+- Group: pick the union of `certctl-*` groups you want to allow.
+- Enabled: on.
+
+## certctl-side configuration
+
+Identical to Keycloak — only the issuer URL differs:
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Authentik",
+    "issuer_url": "https://authentik.example.com/application/o/certctl/",
+    "client_id": "<paste-the-client-id>",
+    "client_secret": "<paste-the-client-secret>",
+    "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+    "groups_claim_path": "groups",
+    "groups_claim_format": "string-array",
+    "fetch_userinfo": false,
+    "scopes": ["openid", "profile", "email", "groups"],
+    "iat_window_seconds": 300,
+    "jwks_cache_ttl_seconds": 3600
+  }'
+```
+
+Authentik emits `groups` in the ID token by default once the property mapping is configured. The `scopes` array MUST include `groups` to trigger the claim emission — Authentik is stricter than Keycloak about scope-gating claims.
+
+Add the group→role mappings the same way as Keycloak: `certctl-engineers` → `r-operator`, `certctl-viewers` → `r-viewer`.
+
+## Verification
+
+End-to-end login + audit + Sessions checks are identical to Keycloak.
+
+**Authentik-specific check:** the audit row's `details.subject` will be Authentik's hashed user ID (a 64-char hex), not the username. This is intentional and correct — the `sub` claim must be opaque + stable across user-attribute changes.
+
+**JWKS-rotation drill:** Authentik rotates signing keys via **System → Tokens & App Passwords → Certificates** (rename of "Crypto" in newer versions). Add a new RSA-2048 cert, switch the Provider's Signing Key to the new one, then click "Refresh discovery cache" in certctl's GUI to evict the cache.
+
+## Troubleshooting
+
+**Provider creation fails with "could not load discovery document".**
+The issuer URL needs the trailing slash for some Authentik versions: `https://authentik.example.com/application/o/certctl/` (slash after the slug). Without the slash, Authentik returns a 301 redirect that Go's HTTP client follows but discovery parsing chokes on the redirect target.
+
+**Login completes but user lands on "no roles assigned".**
+Decode the ID token at jwt.io against Authentik's JWKS. Check whether the `groups` claim is present + non-empty. If empty, the property mapping isn't wired — go back to step 3.
+
+**`groups` claim missing entirely.**
+Authentik gates the `groups` claim behind the `groups` scope. Verify:
+- The certctl OIDCProvider config has `"scopes": ["openid", "profile", "email", "groups"]`.
+- The Authentik provider's "Scopes" list includes `groups`.
+
+**Authentik emits the user's full DN as the `sub` claim.**
+Some Authentik configurations use **Subject mode: Based on the User's email** which surfaces the email as `sub`. This works but tightly couples certctl's User table to email mutability; recommend switching to "hashed ID" mode for new deployments. Existing User rows in certctl's `users` table will have email-shaped `oidc_subject` columns; that's fine and stable as long as the user's email never changes.
+
+## Validation checklist
+
+Same as [keycloak.md](keycloak.md#validation-checklist), with Authentik-specific values for issuer URL + group names + signing-key rotation steps.

+# Microsoft Entra ID (Azure AD) OIDC runbook
+
+> Last reviewed: 2026-05-10
+
+This runbook wires certctl's OIDC SSO surface against [Microsoft Entra ID](https://learn.microsoft.com/entra/), formerly Azure AD. Entra ID is Microsoft's commercial cloud IdP; it's the default IdP for any organization on Microsoft 365 / Azure.
+
+For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Entra-ID-specific deltas.
+
+## The big Entra ID quirk: groups claim emits OBJECT IDs, not names
+
+Entra ID's `groups` claim emits a JSON array of **group object IDs (GUIDs)**, not human-readable names. A user in `Engineering Group` and `Cert Operators` will see something like:
+
+```json
+{
+  "groups": [
+    "8b9b1faa-4e83-471e-8b00-7d99c3e2a5f1",
+    "f00cf1e2-2db1-4cdf-a1ba-1234567890ab"
+  ]
+}
+```
+
+**You must configure your certctl group→role mappings against these GUIDs**, not against `Engineering Group` or `Cert Operators`. There are workarounds (cloud-only group display names + the optional claims path; see the alternative below) but the GUID-based approach is the only one that works reliably across all Entra ID configurations.
+
+This is by design at Microsoft — group names are mutable and not globally unique within a tenant; object IDs are immutable and globally unique. Operators on Microsoft 365 / Azure deployments are accustomed to managing access by GUID.
+
+## Prerequisites
+
+**On the Entra ID side:**
+
+- A Microsoft 365 tenant or standalone Azure AD tenant. Free Azure AD tier is sufficient; paid tiers (P1/P2) unlock conditional access + SCIM provisioning + risk-based auth, none of which are required for the basic OIDC integration.
+- Application Administrator or Global Administrator role.
+- Network reachability from certctl-server to `https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration`.
+
+**On the certctl side:** same as Keycloak.
+
+## IdP-side configuration
+
+### 1. Register the application
+
+In the [Entra ID admin center](https://entra.microsoft.com/):
+
+**Applications → App registrations → New registration**:
+
+- Name: `certctl`.
+- Supported account types: **Accounts in this organizational directory only** (single-tenant; matches the typical operator use case).
+- Redirect URI: **Web** + `https://<your-certctl-host>:8443/auth/oidc/callback`.
+- Click **Register**.
+
+On the saved app's **Overview** page, copy:
+
+- **Application (client) ID** → certctl's `client_id`.
+- **Directory (tenant) ID** → goes into the issuer URL.
+
+### 2. Create a client secret
+
+**App → Certificates & secrets → Client secrets → New client secret**:
+
+- Description: `certctl-server`.
+- Expires: 6 months / 12 months / 24 months — your choice. Set a calendar reminder; Entra ID does NOT auto-rotate secrets.
+- Click **Add**.
+
+Copy the **Value** column immediately — it's shown ONCE on creation. The certctl provider's `client_secret` field gets this value.
+
+(Production hardening: prefer **Certificates** over secrets for client authentication; certctl currently supports `client_secret_post` only, but a follow-on bundle can add `private_key_jwt` for cert-based client auth. Track this if you have a hard requirement against shared secrets.)
+
+### 3. Add the `groups` claim to the token
+
+**App → Token configuration → Add groups claim**:
+
+- Pick **Security groups** (covers most operators) OR **Groups assigned to the application** (more granular but requires Premium).
+- Token type: **ID token** + **Access token** (both, so userinfo fallback works).
+- Customize emit format for ID/access: leave as **Group ID** (default; this is the GUID-based path the runbook is structured around).
+- Click **Save**.
+
+If you instead want display names in the claim (only works for cloud-only groups; on-prem-synced groups continue to emit GUIDs regardless):
+
+- Customize emit format → **Cloud-only group display names**.
+- BUT — note this works only for groups created in Entra ID itself, not groups synced from on-prem AD. Hybrid environments will have inconsistent claims.
+
+### 4. Add the optional `email` and `profile` claims
+
+By default Entra ID's ID token does NOT include `email` — Microsoft considers email part of the "OIDC profile" but only emits it under specific conditions. To force emission:
+
+**App → Token configuration → Add optional claim → ID token → email**.
+
+You may also want `family_name`, `given_name`, `preferred_username` for richer User records on the certctl side.
+
+### 5. Grant the API permissions
+
+**App → API permissions**:
+
+- Microsoft Graph → Delegated permissions → ensure these are granted (most are default):
+  - `openid`
+  - `profile`
+  - `email`
+  - `offline_access` (optional; for refresh tokens — certctl doesn't use them currently).
+- Click **Grant admin consent** if your tenant requires it.
+
+### 6. (Optional) Restrict who can sign in
+
+By default any user in your tenant can attempt to sign in to the app. To restrict to specific users / groups:
+
+**Enterprise applications → certctl → Properties → Assignment required: Yes**.
+Then **Users and groups → Add user/group** and pick the `cert-engineers` / `cert-viewers` Entra ID groups.
+
+## certctl-side configuration
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Entra ID",
+    "issuer_url": "https://login.microsoftonline.com/<tenant-id>/v2.0",
+    "client_id": "<application-id>",
+    "client_secret": "<client-secret-value>",
+    "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+    "groups_claim_path": "groups",
+    "groups_claim_format": "string-array",

+    "scopes": ["openid", "profile", "email"],
+    "iat_window_seconds": 300,
+    "jwks_cache_ttl_seconds": 3600
+  }'
+```
+
+Notes:
+
+- `issuer_url` MUST include `/v2.0` at the end for the v2.0 endpoint. The v1.0 endpoint emits tokens with a different `iss` shape and is NOT supported by certctl. The discovery doc at `https://login.microsoftonline.com/<tenant-id>/v2.0/.well-known/openid-configuration` confirms the right path.
+- `<tenant-id>` is the Directory (tenant) ID GUID from step 1.
+
+### Add the group→role mappings (GUID-keyed)
+
+Get the GUIDs of your engineering / viewer groups:
+
+**Entra ID → Groups → All groups → <group> → Overview → Object ID**.
+
+Then in certctl:
+
+```bash
+# Engineering group → r-operator
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/group-mappings \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "provider_id": "<provider-id>",
+    "group_name": "8b9b1faa-4e83-471e-8b00-7d99c3e2a5f1",
+    "role_id": "r-operator"
+  }'
+```
+
+Repeat for every group you want to map. **Document the GUID-to-name mapping in your operator runbook** — without it, the next operator looking at certctl's mappings page sees a wall of GUIDs with no way to know which is which. Consider naming the mapping descriptively if your group-mapping schema supports it (v2.1.0 doesn't yet — group-mapping descriptions are a parking-lot item for a follow-on release).
+
+## Verification
+
+End-to-end login + audit + Sessions checks are identical to Keycloak.
+
+**Entra-ID-specific:** the audit row's `details.subject` will be Microsoft's `oid` claim (a GUID, the user's object ID), stable across UPN / email changes. The certctl `users` table's `oidc_subject` column holds this GUID.
+
+**JWKS-rotation:** Microsoft auto-rotates signing keys on a documented schedule (every ~6 weeks). The discovery doc + JWKS endpoint always serve the union of active + recently-active keys, so in-flight logins continue to validate. No manual operator action needed in steady state. If you suspect a stuck cache after a Microsoft-side rotation, click "Refresh discovery cache" in the certctl GUI to evict.
+
+## Troubleshooting
+
+**Login completes; ID token contains a `hasgroups: true` claim instead of `groups`.**
+
+Entra ID emits this when a user is in too many groups (>200 by default for ID tokens, >150 for access tokens) — Microsoft truncates the claim and tells the consumer to use Microsoft Graph to look up the full list. certctl does NOT currently support the Graph fallback path (it's a follow-on bundle item).
+
+Workarounds:
+
+- Reduce the user's group membership to <200 (rarely practical in large tenants).
+- Restrict the `groups` claim to "Groups assigned to the application" (Token configuration step 3 above) instead of "Security groups". The "assigned" set is bounded by the app's user assignments and stays under the limit.
+- Use Entra ID's optional `wids` (well-known IDs) claim if you only care about admin/non-admin distinction; certctl can be configured against `wids` by setting `groups_claim_path` accordingly.
+
+**`groups` claim missing entirely.**
+
+Step 3 wasn't completed — Entra ID does NOT emit `groups` by default. Add the claim via Token configuration before users will see it.
+
+**`ErrIssuerMismatch` even though the `tid` in the token matches.**
+
+The v2.0 endpoint emits `iss = https://login.microsoftonline.com/<tenant-id>/v2.0` (no trailing slash). The v1.0 endpoint emits `iss = https://sts.windows.net/<tenant-id>/`. Confirm certctl's `issuer_url` matches v2.0 exactly — no trailing slash, includes `/v2.0`.
+
+**On-prem-synced groups emit GUIDs even when "Cloud-only display names" is selected.**
+
+Expected behavior — Microsoft only emits display names for groups created in Entra ID itself (cloud-only). On-prem-synced groups always emit object IDs. The hybrid case is unfixable from the IdP side; either map against GUIDs (recommended) or migrate the relevant groups to cloud-only.
+
+**The `email` claim is empty even though the user has a primary email.**
+
+Entra ID's `email` claim only populates when:
+1. The user has a "Primary email" set on their Entra ID profile (often blank for B2B guest users).
+2. The optional claim was added in step 4.
+
+For B2B guests, the `preferred_username` claim usually carries the email-shape login. You can configure certctl to use `preferred_username` as the user's display name fallback, but the `User.Email` column will remain blank — that's expected for guests.
+
+**Conditional Access policies blocking the login.**
+
+If your tenant has Conditional Access requiring MFA for new applications, certctl will see the user redirected through the MFA challenge. This works transparently — the certctl service doesn't care that MFA was performed; it only validates the resulting ID token. If MFA is failing for the user, debug at the Entra ID side (Sign-in logs).
+
+## Validation checklist
+
+Same as [keycloak.md](keycloak.md#validation-checklist), with these additions:
+
+- [ ] The ID token's `groups` claim is a string-array of GUIDs (decode at jwt.io).
+- [ ] Each certctl group-mapping uses the GUID, not a human-readable name.
+- [ ] A user with >200 groups successfully logs in (or the operator has documented the limitation + workaround in their internal runbook).
+- [ ] The Entra ID **Sign-in logs** view shows the certctl login event with status "Success".

+# Google Workspace OIDC runbook (broker via Keycloak)
+
+> Last reviewed: 2026-05-10
+
+This runbook wires certctl's OIDC SSO surface against [Google Workspace](https://workspace.google.com/) (formerly G Suite). Google's OIDC implementation has a well-known limitation that makes it unsuitable for direct integration with certctl: **the ID token does not emit a groups claim**, so there is no way for certctl's `ErrGroupsUnmapped` fail-closed contract to resolve a user's role assignment.
+
+The recommended pattern is to **broker Google Workspace through Keycloak (or Authentik)** as a federated identity provider. The end-user still signs in with their Google account, but certctl talks to Keycloak — which DOES emit groups — instead of talking to Google directly.
+
+For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook builds on top of it.
+
+## The Google Workspace quirk in detail
+
+**What Google emits in an ID token:** `iss`, `aud`, `sub`, `azp`, `exp`, `iat`, `email`, `email_verified`, `name`, `picture`, `given_name`, `family_name`, `locale`, `hd` (hosted domain). That's it.
+
+**What it does NOT emit:** `groups`, `roles`, `permissions`, or any indicator of the user's Google Workspace organizational unit / group membership.
+
+There is a **Cloud Identity Groups API** at `https://cloudidentity.googleapis.com/v1/groups/-/memberships:searchTransitiveGroups` that lets a privileged service account look up a user's groups, but:
+
+1. It requires a service account with domain-wide delegation, which is a major security surface to grant to certctl.
+2. It's a separate REST call after the OIDC flow, not a claim — certctl's group-claim resolver is path-shape, not API-shape.
+3. The latency budget of an extra API call per login is non-trivial in steady state.
+
+For these reasons, the broker pattern is strongly preferred. If you absolutely cannot deploy a broker, see "Direct integration without groups" at the bottom of this runbook for a degraded mode where every Google-authenticated user gets a single fixed role.
+
+## Architecture: broker pattern
+
+```
+end user → Google Workspace login → Keycloak (federated IdP) → certctl
+                                       ↑
+                                       │
+                          adds groups claim from Keycloak's group store
+                          (NOT from Google)
+```
+
+In this topology:
+
+- The end user's authentication credentials live at Google.
+- The user's group / role assignments live at Keycloak (manually or via SCIM provisioning from Google).
+- certctl talks ONLY to Keycloak. From certctl's perspective this is identical to the [keycloak.md](keycloak.md) runbook.
+
+## Prerequisites
+
+- A running Keycloak instance with a realm dedicated to certctl. Read [keycloak.md](keycloak.md) and complete that runbook FIRST against a local-only test user. Verify end-to-end OIDC works against Keycloak before adding Google as a federated provider.
+- A Google Workspace tenant where you have Super Admin access OR can ask your Workspace admin to create OAuth credentials.
+- A Google Cloud project (free; same console as Workspace).
+
+## IdP-side configuration
+
+### Step 1: create a Google OAuth client
+
+In the Google Cloud Console (`https://console.cloud.google.com/`):
+
+**APIs & Services → OAuth consent screen → Configure**:
+
+- User Type: **Internal** (restricts to your Workspace domain) OR **External** (any Google account; usually NOT what you want for an internal cert-management tool).
+- App name: `certctl SSO via Keycloak`.
+- User support email: your team's address.
+- Authorized domains: add the domain Keycloak runs on.
+- Save.
+
+**APIs & Services → Credentials → Create Credentials → OAuth client ID**:
+
+- Application type: **Web application**.
+- Name: `certctl-via-keycloak`.
+- Authorized redirect URIs: `https://<keycloak-host>/realms/<realm-name>/broker/google/endpoint` — this is Keycloak's default federated-IdP callback URL. Get the exact URL from Keycloak in step 2 below.
+- Click **Create**.
+
+Copy the **Client ID** and **Client secret**.
+
+### Step 2: add Google as a federated identity provider in Keycloak
+
+In the Keycloak admin console (`https://<keycloak-host>/admin/`):
+
+**Realm → Identity providers → Add provider → Google**:
+
+- Alias: `google` (becomes part of the broker URL).
+- Display name: `Google Workspace`.
+- Client ID: paste from step 1.
+- Client secret: paste from step 1.
+- Default scopes: `openid profile email`.
+- Hosted Domain: your Workspace domain (e.g. `example.com`); restricts to your tenant.
+- Sync mode: **Force** (rewrites the user's first/last name/email from Google on every login; the alternative `Import` only writes on first login).
+- Trust email: **on** (Google verifies emails; certctl-Keycloak chain inherits the trust).
+- Click **Save**.
+
+The **Redirect URI** field at the top of the saved provider's page shows the exact URL you should have entered in Google's console at step 1. Re-verify match.
+
+### Step 3: configure group assignment in Keycloak
+
+This is the load-bearing step — we're explicitly NOT trusting Google for groups, so Keycloak has to provide them.
+
+**Option A: Manual group assignment in Keycloak.**
+
+Federated users from Google appear in **Users** in Keycloak after their first login. You assign them to `certctl-engineers` / `certctl-viewers` / etc. groups in Keycloak's UI manually. Pro: simple. Con: doesn't scale; new hires can't log in until an operator adds them to a group.
+
+**Option B: Default groups via "Default Groups" realm config.**
+
+**Realm settings → User registration → Default Groups → Add**: pick the lowest-privilege group (e.g. `certctl-viewers`). Every new federated user lands here automatically; operators promote individual users to higher groups as needed.
+
+**Option C: Mapper that derives groups from Google claims.**
+
+If your Google Workspace has organizational units that align with your role split, you can add a Keycloak **Identity Provider Mapper** that maps `hd` (hosted domain) or a custom Google directory custom-schema field to a Keycloak group. This is moderately fragile and Workspace-version-dependent; recommend B for most operators.
+
+**Option D: SCIM provisioning from Google to Keycloak.**
+
+Google Workspace can SCIM-push group memberships to Keycloak via the SCIM-for-Google-Cloud-Identity feature. Heavyweight; recommend only if you already have SCIM infrastructure.
+
+This runbook uses **Option B** (default group) for clarity.
+
+### Step 4: verify the broker flow at Keycloak alone
+
+Before bringing certctl into the picture:
+
+1. Log out of Keycloak's admin console.
+2. Hit `https://<keycloak-host>/realms/<realm-name>/account` in an incognito window.
+3. Click "Sign in" — Keycloak's login page should now show **Sign in with Google Workspace** as a button below the local login form.
+4. Click it; authenticate via Google; you should land on Keycloak's account page.
+5. Back in the admin console, the user appears under **Users**. Confirm they're in the default group (Option B).
+
+Only proceed to step 5 when Keycloak alone works end to end.
+
+### Step 5: configure certctl against Keycloak (NOT against Google)
+
+Follow the [keycloak.md](keycloak.md) runbook. Use the realm + client + groups configuration you set up there. The `OIDCProvider.issuer_url` is `https://<keycloak-host>/realms/<realm-name>` — Keycloak's URL, not Google's.
+
+When the user clicks "Sign in with Keycloak" on certctl's login page, the browser flow is:
+
+1. certctl → Keycloak authorize endpoint.
+2. Keycloak's login page shows **Sign in with Google Workspace** + the local login form. User clicks Google.
+3. Keycloak → Google authorize endpoint. User authenticates at Google.
+4. Google → Keycloak callback (`/broker/google/endpoint`). Keycloak resolves the user, assigns the default group.
+5. Keycloak → certctl callback. certctl sees a normal Keycloak ID token with the `groups` claim populated by Keycloak.
+6. certctl mints the session.
+
+End-to-end the user clicks twice (Keycloak's "Sign in with Google" button + Google's consent / login). Subsequent logins skip the consent screen if Google's session is fresh.
+
+## Verification
+
+End-to-end login + audit + Sessions checks are identical to Keycloak. The key Google-Workspace-specific check:
+
+- The `users.oidc_subject` column in certctl's database should contain the Keycloak-side stable subject (a UUID), NOT the Google subject. Decode the certctl-side ID token and confirm `iss` is Keycloak's URL, `sub` is the Keycloak UUID. Don't confuse the certctl ID token with Google's ID token (which lives one hop upstream and certctl never sees directly).
+
+## Direct integration without groups (NOT RECOMMENDED)
+
+If broker deployment is impossible:
+
+1. Configure certctl with `issuer_url = https://accounts.google.com`, `client_id` + `client_secret` from your Google OAuth client (with redirect URI pointed at certctl directly).
+2. Add a SINGLE group→role mapping where `group_name` is the empty string. **Wait — certctl rejects empty group names.** This is the structural reason this mode doesn't work: the fail-closed contract requires a real group claim to match.
+
+The actual workaround is to manually add EVERY operator's email to a per-email mapping, OR to add a custom claim emitter at a thin proxy in front of Google. Both are hacks; the broker pattern is strictly better. We document the constraint here so future operators don't burn cycles trying to make it work.
+
+## Troubleshooting
+
+**Federated Google login completes at Keycloak but the user lands on "no roles assigned" at certctl.**
+
+The user authenticated through Google → Keycloak successfully but Keycloak didn't assign them a group (Option A wasn't completed for that user, or Option B's default group isn't mapped on the certctl side). Check:
+
+- Keycloak → Users → <user> → Groups: is the user in any `certctl-*` group?
+- certctl → Auth → OIDC Providers → Keycloak → Group → role mappings: is that group mapped?
+
+**Google login fails with "redirect_uri_mismatch".**
+
+The Google OAuth client's authorized redirect URI doesn't match Keycloak's broker callback URL exactly. Re-fetch the URL from Keycloak (Identity Providers → Google → Redirect URI field) and paste it verbatim into Google's console.
+
+**Google auto-closes the consent prompt and returns "access_denied".**
+
+Workspace admin policies may block third-party app access. Either the Google OAuth client wasn't approved by the Workspace admin (Google Workspace Admin Console → Security → API controls → Trusted apps), or the OAuth consent screen is configured for "External" but the user is from a different Workspace. Switch to "Internal" if everyone signing in is in the same Workspace.
+
+**Keycloak log shows "Federated identity returned no email claim".**
+
+You requested OAuth scopes other than `openid profile email`. Re-add `email` to the Default Scopes on the Keycloak Identity Provider config.
+
+**Sign-out from certctl doesn't sign the user out of Google.**
+
+Expected. certctl revokes its own session; Google's session continues independently. If the user needs to fully log out, they sign out at https://accounts.google.com/Logout. The certctl + Keycloak chain is the standard "single sign-on, separate sign-outs" model.
+
+## Validation checklist
+
+Same as [keycloak.md](keycloak.md#validation-checklist), with these additions:
+
+- [ ] Google → Keycloak federation works without certctl in the loop (step 4 above passes).
+- [ ] A first-time Google sign-in lands the user in the Keycloak default group (or whatever Option you picked).
+- [ ] The certctl audit row's `details.subject` is the Keycloak UUID, NOT Google's `sub` (which would be a Google account ID).
+- [ ] Removing a user from Google Workspace causes their NEXT certctl session-validate to fail (after their existing session expires) — verify with a deactivated test user.

+# OIDC / SSO runbooks — per-IdP setup guides
+
+> Last reviewed: 2026-05-10
+
+This is the index for the per-IdP setup runbooks for certctl's OIDC SSO surface. Pick the runbook that matches your identity provider; each one walks you through the IdP-side configuration, the certctl-side configuration, end-to-end verification, and the most common troubleshooting paths.
+
+For the threat model behind certctl's OIDC implementation, see [`auth-threat-model.md`](../auth-threat-model.md). For the RBAC primitive that group→role mappings target, see [`rbac.md`](../rbac.md). For the underlying protocol details (PKCE, state, nonce, JWKS rotation, fail-closed semantics), see the OIDC service docstring at [`internal/auth/oidc/service.go`](../../../internal/auth/oidc/service.go).
+
+## Choose your runbook
+
+| IdP | Tier | Group claim shape | Quirks | Runbook |
+|---|---|---|---|---|
+| Keycloak | Free / open-source | `string-array` against `groups` | None — canonical reference | [keycloak.md](keycloak.md) |
+| Authentik | Free / open-source | `string-array` against `groups` | Property-mapping driven; explicit scope claim | [authentik.md](authentik.md) |
+| Okta | Commercial (free dev tier) | `string-array` against `groups` | Group-filter regex on the claim definition | [okta.md](okta.md) |
+| Auth0 | Commercial (free dev tier) | `string-array` against namespaced URL | Custom claims must use a namespaced key (e.g. `https://your-namespace/groups`) and are emitted via an Action | [auth0.md](auth0.md) |
+| Azure AD / Entra ID | Commercial | `string-array` of GROUP OBJECT IDs (GUIDs), not names | Mappings must target object IDs, not human-readable names | [azure-ad.md](azure-ad.md) |
+| Google Workspace | Commercial | NO native group claim | Direct OIDC against Google Workspace cannot emit groups; broker through Keycloak (or Authentik) instead | [google-workspace.md](google-workspace.md) |
+
+## Common shape
+
+Every runbook follows the same five-section layout so you can scan across IdPs:
+
+1. **Prerequisites** — what you need on the IdP side (admin access, plan tier) and on the certctl side (an admin actor holding `auth.oidc.create` + `auth.oidc.edit`, the GUI / CLI / MCP surface available, the `CERTCTL_CONFIG_ENCRYPTION_KEY` env var set in production so client_secret encrypts at rest).
+2. **IdP-side configuration** — clickable steps in the IdP admin console, with the exact field names and values certctl needs.
+3. **certctl-side configuration** — `POST /api/v1/auth/oidc/providers` payloads, plus the GUI and MCP equivalents. The wire shape is the same across every IdP; only the values differ.
+4. **Verification** — what a successful end-to-end login looks like in the audit log and the GUI Sessions page, plus the JWKS-rotation drill.
+5. **Troubleshooting** — the failure modes you're statistically most likely to hit, mapped to the certctl service-layer sentinel error you'll see in the audit row.
+
+## Cross-IdP recurring concepts
+
+These show up in every runbook; understand them once and skim the rest.
+
+**Redirect URI.** Every IdP needs the certctl-side callback URL registered as an allowed redirect URI. The format is `https://<your-certctl-host>/auth/oidc/callback` — port 8443 by default for the HTTPS-only control plane (Decision: post-v2.2 the platform is HTTPS-only, no plaintext port). For local-dev fixtures, `http://localhost:8443/auth/oidc/callback` is acceptable; production deployments MUST use HTTPS, and the OIDCProvider domain validator rejects HTTP issuer URLs in non-test paths.
+
+**Client secret rotation.** Every IdP issues a `client_secret` for the confidential client (certctl is always a confidential client; public clients aren't supported because we have a server-side place to keep the secret). Rotating at the IdP requires the operator to PUT the new secret into certctl via the GUI's "Edit provider" dialog or `certctl_auth_update_oidc_provider` MCP tool — leaving `client_secret` empty in the update payload preserves the existing ciphertext, providing a value rotates.
+
+**JWKS cache TTL.** The certctl service caches the IdP's JWKS document for `jwks_cache_ttl_seconds` (default 3600). When the IdP rotates a signing key, in-flight logins that try to validate a new-key-signed token against the stale cache fail with `ErrJWKSUnreachable` until the next refresh. Operators have two options: wait out the TTL, or click "Refresh discovery cache" in the GUI's OIDC Provider Detail page (`POST /api/v1/auth/oidc/providers/{id}/refresh`) to force-evict the cache. The Keycloak integration test exercises this drill end to end.
+
+**Group→role mappings are fail-closed.** The certctl service refuses to mint a session for a user whose IdP-supplied groups don't match ANY configured mapping (`ErrGroupsUnmapped` → HTTP 401 to the user with a "no roles assigned" page). This is intentional — empty mapping ≠ "let everyone in," it means "this provider is not yet configured for any role." Operators add at least one mapping (typically `<engineers-group>` → `r-operator`) BEFORE rolling out OIDC to users.
+
+**Nonce + state + PKCE-S256 are non-negotiable.** Every login flow round-trips a nonce (replay defense), a state (CSRF defense), and a PKCE-S256 verifier (RFC 9700 §2.1.1 mandate). `plain` PKCE is rejected at the service-layer sentinel level. None of this is configurable; if your IdP doesn't support PKCE-S256, you cannot use it with certctl.
+
+**IdP downgrade-attack defense.** At provider creation AND on every JWKS refresh, certctl intersects the IdP's advertised `id_token_signing_alg_values_supported` with the certctl allow-list (RS256, RS512, ES256, ES384, EdDSA by default). If the IdP advertises HS256/HS384/HS512 or `none`, provider creation is rejected — even before any token is signed under the weak alg. This catches the case where a future compromised or misconfigured IdP tries to rotate to an alg-confusion-prone setup.
+
+## When you finish a runbook
+
+Each per-IdP runbook ends with a **validation checklist** the operator runs against a real production-tier deployment. Run through the matrix end-to-end against your IdP and mark your sign-off in the runbook's footer — that gives the next operator (or the next you) a dated record of what's been verified to work.

+# Keycloak OIDC runbook
+
+> Last reviewed: 2026-05-10
+
+This is the canonical reference runbook for wiring certctl's OIDC SSO surface against [Keycloak](https://www.keycloak.org/). Keycloak is a free / open-source identity provider that runs on-prem or self-hosted; it is also the load-bearing test fixture for certctl's OIDC integration tests (`internal/auth/oidc/testfixtures/keycloak.go`), so the certctl-side validation pipeline is exhaustively exercised against it.
+
+If your IdP is something else (Okta, Auth0, Azure AD, Authentik, Google Workspace), see the per-IdP siblings in [this directory](index.md). The mental model + certctl-side wiring are identical; only the IdP-side console differs.
+
+## Prerequisites
+
+**On the Keycloak side:**
+
+- Keycloak ≥ 25.0 (older versions work but the screen flows differ slightly — the integration test fixture pins 25.0).
+- Admin access to a realm — either an existing tenant realm or a fresh one created for certctl. Don't share Keycloak's `master` realm; create a dedicated realm.
+- Network reachability from certctl-server to the Keycloak `https://<keycloak-host>/realms/<realm-name>` discovery endpoint. The certctl service fetches `/.well-known/openid-configuration` at provider creation and at every `RefreshKeys` call.
+- Keycloak's signing alg set to RS256 (default) or any of: RS512, ES256, ES384, EdDSA. HS256/HS384/HS512 + `none` are rejected by certctl's IdP-downgrade-attack defense at provider creation time.
+
+**On the certctl side:**
+
+- `CERTCTL_CONFIG_ENCRYPTION_KEY` set to a stable secret (production deployments only — the encryption-at-rest layer for the OIDC client_secret depends on it).
+- An admin actor holding `auth.oidc.create` + `auth.oidc.edit` (held by `r-admin` by default; granted via `certctl_auth_assign_role_to_key` MCP tool or the GUI's Auth → Keys page).
+- Server build ≥ v2.1.0.
+
+## IdP-side configuration
+
+The same configuration you'll do by hand here is what the testcontainers fixture imports from `internal/auth/oidc/testfixtures/keycloak-realm.json` — read that file alongside this runbook to see the exact JSON shape Keycloak persists.
+
+### 1. Create or pick a realm
+
+In the Keycloak admin console (`https://<keycloak-host>/admin/`), drop into the realm you'll use. If creating a new one, the realm name will become part of the issuer URL: `https://<keycloak-host>/realms/<realm-name>`.
+
+### 2. Create the OIDC client
+
+**Clients → Create client**:
+
+- Client type: **OpenID Connect**
+- Client ID: `certctl` (or whatever you prefer; it goes into `OIDCProvider.client_id` on the certctl side).
+- Always display in console: off.
+- Click **Next**.
+
+On the capability config page:
+
+- Client authentication: **On** (this makes the client confidential, which is what certctl requires).
+- Authorization: off.
+- Standard flow: **on** (auth-code with PKCE — this is the path certctl uses).
+- Direct access grants: off (ROPC; the test fixture turns this on for ROPC convenience but production should NOT).
+- Implicit flow: off.
+- Service accounts roles: off.
+- Click **Next**.
+
+Login settings:
+
+- Root URL: leave blank.
+- Home URL: blank.
+- Valid redirect URIs: `https://<your-certctl-host>:8443/auth/oidc/callback` — ONE entry, exact match. Wildcards (`*`) work for local dev (`http://localhost:*`) but production should pin the exact host.
+- Valid post logout redirect URIs: blank or `+` (matches the redirect URI list).
+- Web origins: `+` (matches the redirect URI origin) or empty.
+- Click **Save**.
+
+On the saved client's **Credentials** tab, copy the **Client secret** — you'll need it for the certctl-side payload.
+
+### 3. Create the groups
+
+**Groups → Create group**:
+
+- Repeat for every certctl role you want to map to a group. A typical setup creates two:
+  - `certctl-engineers` (intended target: `r-operator`)
+  - `certctl-viewers` (intended target: `r-viewer`)
+- Optionally an `certctl-admins` group → `r-admin` for break-glass-free first-admin bootstrap; see the [`auth-threat-model.md`](../auth-threat-model.md) section on bootstrap admins.
+
+### 4. Configure the group-membership claim mapper
+
+This is the load-bearing step — without it, the ID token won't carry a `groups` claim and every login fails closed with `ErrGroupsUnmapped`.
+
+**Clients → certctl → Client scopes → certctl-dedicated → Add mapper → By configuration → Group Membership**:
+
+- Name: `groups`
+- Token Claim Name: `groups`
+- Full group path: **off** (so the claim emits `engineers`, not `/engineers`; matches the certctl `string-array` group-claim format).
+- Add to ID token: **on**.
+- Add to access token: **on** (optional but recommended; the userinfo-fallback path uses it).
+- Add to userinfo: **on**.
+- Click **Save**.
+
+### 5. Create the user(s)
+
+**Users → Add user**:
+
+- Username: `alice` (or however you identify operators).
+- Email: required (used as the certctl-side `User.Email`).
+- First name + last name: optional but populates `User.DisplayName`.
+- Email verified: **on** if you trust the user.
+- Click **Create**.
+
+On the saved user's **Credentials** tab:
+- Set a password. Mark **Temporary** if you want the user to reset on first login.
+
+On the **Groups** tab:
+- Join the user to the group(s) you created in step 3.
+
+## certctl-side configuration
+
+### Via the GUI
+
+1. Sign in as an admin actor.
+2. Navigate to **Auth → OIDC Providers** in the sidebar.
+3. Click **Configure provider**.
+4. Fill in:
+   - **Display name**: `Keycloak` (free-text; what end-users see on the login page button).
+   - **Issuer URL**: `https://<keycloak-host>/realms/<realm-name>`.
+   - **Client ID**: `certctl` (matches step 2 above).
+   - **Client secret**: paste the secret from step 2's Credentials tab.
+   - **Redirect URI**: `https://<your-certctl-host>:8443/auth/oidc/callback`.
+   - **Groups claim path**: `groups` (the default; matches step 4's Token Claim Name).
+   - **Groups claim format**: `string-array` (the default).
+   - **Fetch userinfo**: off (Keycloak emits groups in the ID token; userinfo fallback is for IdPs that don't).
+   - **Scopes**: `openid profile email` (the certctl service prepends `openid` if missing).
+   - **IAT window seconds**: 300 (default).
+   - **JWKS cache TTL seconds**: 3600 (default).
+5. Click **Save**.
+
+If the discovery doc fetch fails, the modal surfaces the error inline. The most common cause is a typo in the issuer URL — Keycloak emits 404 for any path under `/realms/` that doesn't match an actual realm.
+
+### Via the API
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Keycloak",
+    "issuer_url": "https://keycloak.example.com/realms/certctl",
+    "client_id": "certctl",
+    "client_secret": "<paste-the-secret>",
+    "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+    "groups_claim_path": "groups",
+    "groups_claim_format": "string-array",
+    "fetch_userinfo": false,
+    "scopes": ["openid", "profile", "email"],
+    "iat_window_seconds": 300,
+    "jwks_cache_ttl_seconds": 3600
+  }'
+```
+
+### Via MCP
+
+```
+certctl_auth_create_oidc_provider {
+  "name": "Keycloak",
+  "issuer_url": "https://keycloak.example.com/realms/certctl",
+  "client_id": "certctl",
+  "client_secret": "<paste-the-secret>",
+  "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+  "groups_claim_path": "groups",
+  "groups_claim_format": "string-array",
+  "scopes": ["openid", "profile", "email"]
+}
+```
+
+### Add the group→role mappings
+
+GUI: **Auth → OIDC Providers → Keycloak → Group → role mappings → Add**.
+
+- IdP group: `certctl-engineers` → certctl role: `r-operator`.
+- IdP group: `certctl-viewers` → certctl role: `r-viewer`.
+
+API equivalent: `POST /api/v1/auth/oidc/group-mappings` with `{"provider_id": "<id>", "group_name": "certctl-engineers", "role_id": "r-operator"}`. MCP equivalent: `certctl_auth_add_group_mapping`.
+
+Empty mapping list = nobody can log in via Keycloak (the fail-closed contract). Add at least one before announcing the SSO endpoint to users.
+
+## Verification
+
+### End-to-end login
+
+1. Open `https://<your-certctl-host>:8443/login` in a fresh incognito window.
+2. The page renders an OIDC button block with `Sign in with Keycloak` (the display name from the create-provider step).
+3. Click it. The browser redirects to Keycloak, you authenticate as `alice`, Keycloak redirects back to certctl, and you land on the dashboard.
+4. Navigate to **Auth → Sessions**. You should see a row with your own actor ID, the IP you logged in from, and the current timestamp under "last seen".
+
+### Audit trail
+
+```bash
+curl https://<your-certctl-host>:8443/api/v1/audit?category=auth \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" | jq '.events[] | select(.action == "auth.oidc_login_succeeded")'
+```
+
+You should see a row for the login above, with `details.provider_id` matching the Keycloak provider's id and `details.subject` set to the Keycloak user's `sub` claim (typically a UUID).
+
+### JWKS-rotation drill
+
+Operator action when Keycloak rotates its realm signing key:
+
+1. In Keycloak: **Realm settings → Keys → Providers → Add provider → rsa-generated**, set priority higher than the current key (e.g. 200), enabled = on, active = on.
+2. In certctl: GUI → **Auth → OIDC Providers → Keycloak → Refresh discovery cache** button. Or the CLI / MCP equivalent: `POST /api/v1/auth/oidc/providers/<id>/refresh`.
+3. Run another login. The new ID token is signed under the new key; the certctl service validates it against the freshly-fetched JWKS doc.
+
+The Keycloak integration test `TestKeycloakIntegration_JWKSRotation_RefreshKeysPicksUpNewKey` exercises this exact flow end to end.
+
+## Troubleshooting
+
+**"Discovery doc fetch failed" at provider creation.**
+The most common cause is a wrong issuer URL — typo in realm name, missing `/realms/` segment, or HTTP→HTTPS redirect that the Go client doesn't follow without explicit headers. Curl the URL manually:
+```
+curl -v https://<keycloak-host>/realms/<realm-name>/.well-known/openid-configuration
+```
+If that returns 404, fix the realm name. If it returns 200 but certctl still fails, check `cmd/server` logs for the wrapped error.
+
+**"IdP downgrade-attack defense" rejected provider creation.**
+Keycloak's realm has a signing key advertised in `id_token_signing_alg_values_supported` that's in certctl's deny-list (HS256/HS384/HS512/`none`). Check **Realm settings → Keys → Providers** — disable any HMAC key providers and re-create the provider in certctl.
+
+**Login redirects to Keycloak, the user authenticates, but the callback redirects back to `/login` with "no roles assigned".**
+The user authenticated successfully but their groups didn't match any configured mapping (`ErrGroupsUnmapped`). Check:
+- The user is actually a member of the group you mapped (Users → user → Groups tab in Keycloak).
+- The group-membership mapper is configured correctly (Clients → certctl → Client scopes → certctl-dedicated → mappers → groups → "Full group path: off" matters).
+- The group name in your certctl mapping exactly matches what Keycloak emits — case-sensitive, no leading slash if "Full group path: off".
+
+You can confirm what Keycloak is actually emitting by decoding the ID token at jwt.io against the Keycloak public key, or by enabling certctl's debug logging on the OIDC service for one login (logs are scrubbed of token contents per the OIDC service's token-leak hygiene contract; debug logs surface only the resolved group list and the mapping decision).
+
+**"id_token verify failed: token used before issued"**
+Clock skew between Keycloak and certctl-server. Either align both to NTP, or bump `iat_window_seconds` on the OIDC provider config (default 300 = 5 minutes). The certctl service caps `iat_window_seconds` at 600.
+
+**"oidc: pre-login session not found or already consumed"**
+The user clicked the OIDC login button, then the browser tab idled past the 10-minute pre-login TTL OR the user opened the IdP login in a new tab and consumed the row from the first one. Have them retry.
+
+**"oidc: state parameter mismatch (replay or forgery)"**
+Either the user double-submitted a callback URL (clicked it twice from email or browser history), or a CSRF attempt. The pre-login row is single-use; second consumption returns `ErrPreLoginNotFound`. Have them retry from the login page.
+
+**Sessions revoked but the user can still hit the API.**
+Check the session contract: the cookie is HMAC-validated on every request, but the actual database row is what `Revoke` deletes. If your reverse proxy is caching the response or the `__Host-certctl_session` cookie wasn't actually cleared on the client, the cookie will hit the server's session middleware which will return 401 on the missing-row lookup. The middleware never serves stale data; the issue is upstream of certctl in this case.
+
+## Validation checklist
+
+Before signing off this runbook for production rollout, validate these end-to-end:
+
+- [ ] `auth.oidc_provider_created` audit row appears after the create-provider POST.
+- [ ] `Sign in with Keycloak` button renders on the login page after `getAuthInfo` returns the configured provider.
+- [ ] A user with mapped groups completes the auth-code flow and lands on the dashboard.
+- [ ] A user WITHOUT mapped groups gets the "no roles assigned" landing (not the dashboard).
+- [ ] The `auth.oidc_login_succeeded` and `auth.oidc_login_failed` audit rows correctly distinguish the two cases.
+- [ ] The Sessions page shows the new session, with self-pill on the caller's row.
+- [ ] Revoking the session via the GUI causes the next API request from that browser to 401 + redirect to login.
+- [ ] Running the JWKS-rotation drill (steps above) does not break in-flight logins; rotated tokens validate against the refreshed JWKS.
+- [ ] Editing the provider with `client_secret` blank preserves the existing ciphertext (operator confirms by reading the `oidc_providers.client_secret_encrypted` column before + after the PUT — bytes unchanged).

+# Okta OIDC runbook
+
+> Last reviewed: 2026-05-10
+
+This runbook wires certctl's OIDC SSO surface against [Okta](https://www.okta.com/), a commercial cloud IdP. Okta offers a free developer tier (`https://dev-NNNNN.okta.com`) suitable for evaluation; production runs on a paid Workforce Identity tenant.
+
+For the canonical reference + mental model, read [keycloak.md](keycloak.md) first; this runbook only documents the Okta-specific deltas.
+
+## Prerequisites
+
+**On the Okta side:**
+
+- A Workforce Identity tenant (or free Developer Edition account at <https://developer.okta.com/signup/>).
+- Super Admin or Application Admin role in your Okta tenant.
+- Network reachability from certctl-server to `https://<your-org>.okta.com/.well-known/openid-configuration` OR to a custom authorization server endpoint if you're using one (`https://<your-org>.okta.com/oauth2/<auth-server-id>/.well-known/openid-configuration`).
+
+**On the certctl side:** same as Keycloak.
+
+## IdP-side configuration
+
+### 1. Create the OIDC application
+
+In the Okta admin console:
+
+**Applications → Applications → Create App Integration**:
+
+- Sign-in method: **OIDC - OpenID Connect**.
+- Application type: **Web Application**.
+- Click **Next**.
+
+App config:
+
+- App integration name: `certctl`.
+- Logo: optional.
+- Grant types: **Authorization Code** (CHECK). Leave Refresh Token unchecked unless you have a specific reason — certctl doesn't currently use refresh tokens.
+- Sign-in redirect URIs: `https://<your-certctl-host>:8443/auth/oidc/callback`.
+- Sign-out redirect URIs: optional; leave empty unless you also configure RP-initiated logout.
+- Trusted Origins: leave default.
+- Assignments → Controlled access: **Limit access to selected groups** (recommended; pick the `certctl-*` groups from step 3 below).
+- Click **Save**.
+
+On the saved app's **General** tab, copy the **Client ID** and **Client secret** (under Client Credentials). The secret is shown once on creation — copy it immediately or rotate via "Generate new secret".
+
+### 2. Pick or create an authorization server
+
+Okta has TWO authorization-server tiers:
+
+- **The Org Authorization Server** at `https://<your-org>.okta.com` — emits ID tokens with limited claims; cannot host custom claims directly. Use for the simplest setup.
+- **A Custom Authorization Server** at `https://<your-org>.okta.com/oauth2/<auth-server-id>` — fully configurable scopes + claims + access policies. The free developer tier ships with a default custom server at `/oauth2/default`. Recommended for production.
+
+For this runbook we use the default custom server: `https://<your-org>.okta.com/oauth2/default`.
+
+### 3. Create the groups + assign users
+
+**Directory → Groups → Add Group**:
+
+- Repeat for `certctl-engineers`, `certctl-viewers`, optionally `certctl-admins`.
+
+**Directory → People → <user> → Groups**: assign each user to the appropriate `certctl-*` group(s).
+
+Then go back to the App from step 1 and on the **Assignments** tab, assign the `certctl-*` groups to the application. Without this assignment Okta will reject the user's login attempt at the IdP layer with "User is not assigned to the client application".
+
+### 4. Configure the groups claim
+
+This is the load-bearing Okta-specific step. The default authorization server does NOT emit a `groups` claim out of the box — you have to define it.
+
+**Security → API → Authorization Servers → default → Claims → Add Claim**:
+
+- Name: `groups`.
+- Include in token type: **ID Token, Always** (also tick Access Token if you want the userinfo-fallback path to work).
+- Value type: **Groups**.
+- Filter: pick **Matches regex** with the value `certctl-.*` so only the `certctl-*` groups are emitted (saves on token size; users in dozens of unrelated groups get a bloated token otherwise).
+- Disable claim: off.
+- Include in: **Any scope** (or pin to `openid` if you want the claim only on the certctl-flow).
+- Click **Create**.
+
+### 5. (Optional) Add `email` and `profile` claims
+
+The default custom server already emits `email` and `name` under the `profile` and `email` scopes — no action needed unless you've stripped them from a custom config.
+
+## certctl-side configuration
+
+```bash
+curl -X POST https://<your-certctl-host>:8443/api/v1/auth/oidc/providers \
+  -H "Authorization: Bearer ${CERTCTL_API_KEY}" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "name": "Okta",
+    "issuer_url": "https://your-org.okta.com/oauth2/default",
+    "client_id": "<paste-from-step-1>",
+    "client_secret": "<paste-from-step-1>",
+    "redirect_uri": "https://certctl.example.com:8443/auth/oidc/callback",
+    "groups_claim_path": "groups",
+    "groups_claim_format": "string-array",
+    "fetch_userinfo": false,
+    "scopes": ["openid", "profile", "email"],
+    "iat_window_seconds": 300,
+    "jwks_cache_ttl_seconds": 3600
+  }'
+```
+
+Notes:
+
+- `issuer_url` MUST match exactly what Okta emits as the `iss` claim. For the default custom server it's `https://<your-org>.okta.com/oauth2/default` (no trailing slash). The org server's issuer is just `https://<your-org>.okta.com` (no `/oauth2/...` path). Mismatching either side trips certctl's `ErrIssuerMismatch` sentinel.
+- The `groups` scope is NOT required in the scopes list — Okta emits the claim based on the claim definition's "Include in: any scope" setting. Adding `groups` to the scopes list is harmless if your custom server has the scope defined.
+
+Add the group→role mappings: `certctl-engineers` → `r-operator`, `certctl-viewers` → `r-viewer`, `certctl-admins` → `r-admin`.
+
+## Verification
+
+End-to-end login + audit + Sessions checks are identical to Keycloak.
+
+**Okta-specific:** the audit row's `details.subject` will be Okta's user UID (a 20-char alphanumeric string starting with `00u`), stable across email changes. The certctl `users` table's `oidc_subject` column will hold this UID.
+
+**Optional Okta smoke test in CI:** certctl ships an opt-in smoke test at `internal/auth/oidc/integration_okta_smoke_test.go` (build tags `integration && okta_smoke`). Set `OKTA_ISSUER` + `OKTA_CLIENT_ID` + `OKTA_CLIENT_SECRET` env vars and run `make okta-smoke-test` to drive a discovery + RefreshKeys round-trip against your live tenant. Pre-reqs: enable the Resource Owner Password (ROPC) grant on the application (Sign-On tab → Grant types → Resource Owner Password) for the smoke test only; production certctl uses auth-code-with-PKCE.
+
+**JWKS-rotation drill:** Okta auto-rotates signing keys every ~3 months and publishes the new key alongside the old in the JWKS doc for ~1 month overlap. Manual rotation: **Security → API → Authorization Servers → default → Keys → "Generate new key"**. After rotation, click "Refresh discovery cache" in certctl's GUI; new tokens validate immediately.
+
+## Troubleshooting
+
+**"User is not assigned to the client application" at the Okta login screen.**
+You created the app + the user but didn't assign the user to the app via a group. Either assign the user directly (App → Assignments → Assign to People) or assign the `certctl-*` groups to the app (App → Assignments → Assign to Groups).
+
+**Login completes but `groups` claim is empty in the ID token.**
+Most common Okta gotcha — the default custom server doesn't emit `groups` until you define the claim (step 4 above). Decode the ID token at jwt.io to confirm. If the claim is defined but empty, check the regex filter in step 4 — `certctl-.*` matches names like `certctl-engineers` but NOT `engineers`.
+
+**`ErrIssuerMismatch` after correctly configuring the discovery URL.**
+The issuer claim Okta puts in the ID token MUST match `OIDCProvider.IssuerURL` byte-for-byte, including trailing slash. The default custom server emits `https://<your-org>.okta.com/oauth2/default` (no trailing slash); the org server emits `https://<your-org>.okta.com`. Don't append a trailing slash to either.
+
+**Login succeeds but the certctl `User.Email` is empty.**
+The `email` scope wasn't requested OR the user's email isn't verified at Okta. Add `email` to the certctl scopes config and ensure Okta's user has a verified primary email.
+
+**Okta returns "PKCE code verifier required".**
+The certctl service hard-codes PKCE-S256 on every login (RFC 9700 mandate). If Okta is rejecting the verifier, the most likely cause is a misconfigured app type — confirm the Okta application is "Web Application" (which supports auth-code + PKCE), not "Single-Page Application" (which has different token-binding rules) or "Native App".
+
+**Custom-server access policies blocking the login.**
+By default the `default` custom authorization server has an "Access Policy" with one rule allowing all clients + all users. If you've tightened this (production hygiene), add a rule that allows the `certctl` client + the `certctl-*` groups: **Security → API → Authorization Servers → default → Access Policies → <policy> → Add Rule**.
+
+## Validation checklist
+
+Same as [keycloak.md](keycloak.md#validation-checklist), with Okta-specific values + the access-policy check above.
