shankar0123 69f860171e auth-bundle-1 Phase 0: extract internal/auth/ from middleware package
Bundle 1 / Phase 0: pure refactor splitting auth surface out of internal/api/middleware so Bundle 2 (OIDC + sessions) and the broader RBAC primitive (roles, permissions, scoped grants) have a clean home.

Moved to internal/auth/: NamedAPIKey, HashAPIKey, AuthConfig, NewAuthWithNamedKeys, NewAuth, UserKey, AdminKey, GetUser, IsAdmin. Added testfixtures.go (WithActor / WithAdmin / WithActorAdmin) so handler tests don't construct context manually.

Stayed in internal/api/middleware/: RequestID, Logging, NewLogging, Recovery, RateLimitConfig, NewRateLimiter (now imports auth.GetUser for per-user keying per audit Category C), CORSConfig, NewCORS, ContentType, CORS, GetRequestID, responseWriter, Chain, audit middleware (now imports auth.GetUser).

Updated 22 caller files across cmd/, internal/api/handler/, internal/api/middleware/, internal/mcp/. Existing m008_admin_gate_test.go now scans for auth.IsAdmin( substring; Phase 3 will further evolve to track auth.RequirePermission. Behavior unchanged: all handler / middleware / service / connector / cmd / mcp tests pass with no test-logic edits, only import-path renames.

Phase 0 exit criteria: internal/auth/ exists with 6 files; middleware.go went 575 -> 422 lines (auth-related ~150 lines moved out); grep -rE 'middleware\.(GetUser|IsAdmin|UserKey|AdminKey|NamedAPIKey|HashAPIKey|NewAuth)' returns 0 hits; context.WithValue(.*middleware.UserKey/AdminKey) returns 0 hits; go vet ./... clean; go test -short ./... green across all packages tested.

Branch: dev/auth-bundle-1. Per cowork/auth-bundle-1-prompt.md, do not merge to master without (1) make verify green, (2) >= 2 external testers confirm, (3) >= 90% coverage on internal/auth/ in .github/coverage-thresholds.yml.

shankar0123 2db100124f cli: promote --force on renew + require --reason on revoke (closes P3-1, P3-2)
Closes findings P3-1 and P3-2 from the 2026-05-05 CLI/API/MCP↔GUI parity
audit (cowork/cli-gui-parity-audit-2026-05-05/RESULTS.md). Both findings
flagged hidden defaults that the CLI was sending without exposing them
to operators: `force=false` baked into every renew payload, and a silent
fallback to `reason="unspecified"` whenever --reason was omitted.

P3-1 — promote --force on `certs renew` (full end-to-end plumbing)

The pre-2026-05-05 CLI sent `{"force": false}` in the renew body. The
API handler never decoded it — a textbook "lying field" per the
operator's CLAUDE.md "complete path, not the easy path" rule: the body
field stored a value, claimed to do something, and silently did nothing
because the wire never reached the consumer. Adding a --force flag that
also went unread would have created another lying field.

This commit takes the complete path:

  service.CertificateService.TriggerRenewal grew a `force bool` parameter
  (internal/service/certificate.go). When force=true, the
  RenewalInProgress block is overridden so operators can recover stuck
  in-flight renewals where a previous job hung without releasing the
  status flag. Archived and Expired remain terminal blockers regardless
  of force — those are semantic dead-ends that --force should not paper
  over (archived = decommissioned, expired = issue a new cert instead of
  renewing a dead one).

  handler.CertificateHandler.TriggerRenewal parses force from
  ?force=true (or ?force=1) query param, OR {"force": true} JSON body,
  whichever the client picks. Defaults to false. Passes through to the
  service.

  internal/cli/client.go::RenewCertificate(id, force bool) sends
  ?force=true on the URL when --force is set. The historical hardcoded
  `{"force": false}` body is gone — no more lying field.

  cmd/cli/main.go dispatches `certs renew <id> [--force]` (ID-first
  flag-second convention matches the existing `agents retire <id>
  [--force]`).

P3-2 — require --reason on `certs revoke` (Option A: strict refusal)

The pre-2026-05-05 CLI dropped to `--reason unspecified` whenever the
operator omitted the flag. Compliance reporting (RFC 5280 §5.3.1, PCI-
DSS §3.6, HIPAA §164.312) relies on the reason code being meaningful;
silent fallback defeats the audit trail because every revocation looks
identical.

  cmd/cli/main.go dispatch refuses to send when --reason is empty,
  prints the canonical RFC 5280 §5.3.1 reason-code menu, and exits
  non-zero.

  internal/cli/client.go exposes ValidRevokeReasons() returning the
  canonical camelCase list (unspecified, keyCompromise, caCompromise,
  affiliationChanged, superseded, cessationOfOperation, certificateHold,
  removeFromCRL, privilegeWithdrawn, aaCompromise) and
  NormalizeRevokeReason() that accepts both camelCase and snake_case
  inputs and normalises to the canonical wire form. Off-list reasons
  are rejected at dispatch with the menu re-printed.

Test pins:

  internal/cli/client_test.go::TestClient_RenewCertificate_ForceFlag —
  --force=true sends ?force=true with empty body; --force=false sends
  no query and no body.

  internal/cli/client_test.go::TestNormalizeRevokeReason +
  TestValidRevokeReasons — canonical-camelCase + snake_case + reject-
  off-enum behaviour.

  cmd/cli/dispatch_test.go::TestHandleCerts_Revoke_RequiresReason +
  TestHandleCerts_Revoke_RejectsUnknownReason +
  TestHandleCerts_Renew_ForceFlag — dispatch-layer pins for the same
  contracts.

  internal/api/handler/certificate_handler_test.go::TestTriggerRenewal_
  ForceQueryParam — query-param passthrough (no-flag, force=true,
  force=1, force=false) flows through to the service-layer parameter.

  internal/service/certificate_test.go::TestTriggerRenewal_
  ForceOverridesInProgress — force=false preserves the
  RenewalInProgress block; force=true clears it.

  Existing TestTriggerRenewal_Archived extended to assert force=true
  still blocks Archived (terminal-state guarantee).

Docs: docs/reference/cli.md updated with the --force example for renew
and the strict --reason semantics for revoke (including snake_case
input acceptance).

Acceptance gate (verified):
  - go build ./cmd/server/... ./cmd/agent/... ./cmd/cli/...
    ./cmd/mcp-server/... clean.
  - go vet ./... clean.
  - go test -short -count=1 ./... pass repo-wide.
  - bash scripts/ci-guards/openapi-handler-parity.sh clean
    (router 178, OpenAPI 144, exceptions 36 — unchanged; we add
    parameter parsing, not routes).
  - gofmt -l clean.

shankar0123 2690b6401a refactor(scep+ejbca): drop dead conditionals on always-empty vars (CodeQL #18, #19)
Two CodeQL go/comparison-of-identical-expressions alerts in one
sweep — both Warning severity, both real dead-code (not false
positives). CodeQL detected that each comparison's LHS variable
was provably constant.

Alert #18 — internal/api/handler/scep.go:612 (extractCSRFields):

  challengePassword := ""
  transactionID := ""
  // ... loop populates challengePassword from CSR.Attributes ...
  for _, attr := range csr.Attributes {
      if attr.Type.Equal(oidChallengePassword) {
          // populates challengePassword ONLY — transactionID stays ""
      }
  }
  if transactionID == "" && csr.Subject.CommonName != "" {  // ← always true
      transactionID = csr.Subject.CommonName
  }

  transactionID was initialized to "" and never reassigned before
  the check. The conditional was always true; the MVP path was
  effectively "unconditionally fall back to CN". The RFC 8894 path
  (tryParseRFC8894 above this function) extracts transaction-ID
  properly from PKCS#7 authenticatedAttributes; the MVP path is for
  lightweight legacy clients that send the raw CSR with no PKCS#7
  wrapping, and CN-as-transaction-ID is sufficient there.

  Fix: drop the dead transactionID local var + dead conditional;
  unconditionally set transactionID = csr.Subject.CommonName. No
  behavioral change — the runtime semantics are identical to before
  (every valid invocation already took the fallback). The CN
  extraction stays robust because the empty-CN case still produces
  an empty transactionID, which downstream callers handle.

Alert #19 — internal/connector/issuer/ejbca/ejbca.go:415 (RevokeCertificate):

  serial := request.Serial
  issuerDN := ""
  // (comment: "if we have time..." — TODO never followed up)
  revokeURL := fmt.Sprintf("%s/certificate/%s/%s/revoke", apiURL, issuerDN, serial)
  if issuerDN == "" {  // ← always true
      revokeURL = fmt.Sprintf("%s/certificate/%s/revoke", apiURL, serial)
  }

  issuerDN was hardcoded to "" two lines above. The first revokeURL
  line was unreachable dead code; the conditional always fired and
  the serial-only URL always won. EJBCA's REST API has both
  /certificate/{issuer_dn}/{serial}/revoke and /certificate/{serial}/revoke
  endpoints; the serial-only form is correct for typical certctl
  deployments where one EJBCA CA maps to one certctl issuer config
  (no overlapping serial spaces).

  Fix: drop the dead first revokeURL + dead conditional; build
  revokeURL once via the serial-only endpoint. No behavioral change
  — the runtime URL was always the serial-only one. Comment retained
  + expanded to document the future-enhancement path (parse issuer
  DN from IssuanceResult metadata + use the DN-qualified endpoint
  when a multi-CA EJBCA deployment surfaces).

Verified locally:
  gofmt: clean.
  go vet ./internal/api/handler/... + ./internal/connector/issuer/ejbca/...: exit 0.
  go test -short -count=1 ./internal/api/handler/... + ejbca/...: PASS.
  Both fixes are pure dead-code removal — runtime behavior is byte-
  identical to pre-edit. The existing test suites would have caught
  any actual behavioral change.

shankar0123 dcc28bf113 Revert "chore: drop 'Infisical' label from internal references"
This reverts commit 2886b58daf.
2026-05-04 01:18:15 +00:00
shankar0123 2886b58daf chore: drop 'Infisical' label from internal references
Strategic naming cleanup. Earlier doc-comments + commit messages framed Rank
4 / Rank 5 / Rank 7 work as 'Rank N of the 2026-05-03 Infisical deep-research
deliverable' — the 'Infisical' qualifier was a holdover from the original
deep-research framing where Infisical (a competing secrets-management
platform) was the comparator. Keeping the comparator's name in our source
adds noise without value; an external reader sees 'Infisical' and assumes a
dependency or shared lineage rather than reading it as the competitive
context it was.

Mechanical sed across 34 files (32 source / docs + 2 follow-up Python passes
to collapse 'deep-research deep-research' duplicates that emerged where the
original phrase wrapped across lines):

  s|Infisical deep-research|deep-research|g
  s|infisical-deep-research-results|deep-research-results-2026-05-03|g
  s|infisical-deep-research-prompt|deep-research-prompt-2026-05-03|g
  s|infisical-deep-research|deep-research|g
  s|Infisical|deep-research|g
  s|deep-research deep-research|deep-research|g  # collapse-pass

Net diff: 63 insertions / 64 deletions across cmd/, docs/, internal/,
migrations/. Pure text substitution; zero behavior change. Code path
unchanged — go vet clean, tests for TestApproval pass on both
internal/service and internal/api/handler packages.

Workspace docs (cowork/) carry the same references and will be swept
separately — they're not under certctl/ git control. The two filename
references (cowork/infisical-deep-research-results.md +
cowork/infisical-deep-research-prompt.md) get renamed alongside that sweep
to deep-research-results-2026-05-03.md /
deep-research-prompt-2026-05-03.md so cross-references in the certctl
repo doc-comments resolve cleanly.

Note on OpenAPI spec: the prompt's spec section also calls for 5 new

getApprovalRequest, approveApprovalRequest, rejectApprovalRequest). The
external-create endpoint is intentionally not implemented in V2 — every
approval request originates from the renewal-loop entry points (commit 4)
so the only operations exposed are list / get / approve / reject. The
4-route surface is a deliberate scope cut: external systems wanting to
inject approval requests can use the underlying `POST /api/v1/certificates/
{id}/renew` path which creates the parallel ApprovalRequest as a side
effect (post-commit-4 wiring). OpenAPI extension batched into commit 4
alongside the integration changes.

shankar0123 5dc698307b chore: rename Go module path to github.com/certctl-io/certctl
Mechanical sed across the main go.mod's module declaration, the f5-mock-icontrol
sub-module's go.mod, every Go file's import path (361 files), and a rebuild of
the checked-in f5-mock-icontrol binary so its embedded build-info reflects the
new module path. No behavior change.

Choice B from cowork/transfer-certctl-to-org.md, executed 2026-05-04. Choice A
(keep module path declared as github.com/shankar0123/certctl regardless of
repo URL) shipped on the day of the org transfer (2026-05-03) since we had no
external Go consumers; this commit closes that deferral.

Backward-compat: GitHub HTTP redirects continue to forward
github.com/shankar0123/certctl → github.com/certctl-io/certctl at the URL
level, but Go's module proxy uses the path declared in go.mod as the
canonical name. Pre-fix, anyone trying `go get github.com/certctl-io/certctl/...`
hit a "module path mismatch" error because go.mod said
github.com/shankar0123/certctl and the URL they fetched it from said
certctl-io/certctl. Post-fix, the canonical name and the URL agree, so
go get / go install / external Go consumers / Go-tooling integrations
work cleanly via either the new path (preferred) or the old path (which
redirects and Go follows the redirect for source fetch).

Anyone still importing the old path inside their own code keeps working
provided they update their go.mod's `require` line to match — the module
path declared in their consumer's go.sum / go.mod is the authoritative
import name, so a mass sed across their import statements is the migration
on the consumer side. No external consumers exist today.

Diff shape:
  361 *.go files  — import path replacement only
    2 go.mod     — module declaration replacement only
    1 binary     — deploy/test/f5-mock-icontrol/f5-mock-icontrol rebuilt
                   so embedded build-info reflects the new path (8618965 vs
                   8618933 bytes; 32-byte diff is the build-info change)

  Total: 364 files, 730 insertions / 730 deletions, net-zero size, pure
  mechanical substitution.

Verification:
  gofmt: 17 files needed re-alignment after sed (the new path is one char
    shorter than the old, so column-aligned import groups drifted). Applied
    `gofmt -w` to fix.
  go mod tidy: clean exit on both modules.
  go vet ./...: clean exit.
  go build ./...: clean exit.
  go test -short -count=1 on representative packages: all green
    (internal/domain, internal/validation, internal/crypto, internal/crypto/signer,
    cmd/agent). Test output now reads `ok github.com/certctl-io/certctl/...`
    confirming the module path resolves correctly.
  binary: f5-mock-icontrol rebuilt; `strings | grep shankar0123` returns
    nothing; `strings | grep certctl-io/certctl` shows the new module path
    embedded in build-info.

Files intentionally NOT touched in this commit:
  README.md / CHANGELOG.md / docs/ / etc. — already swept to certctl-io
    URLs in commit bc6039a (the post-transfer URL refresh). This commit is
    purely the Go-tooling layer.
  Scarf pixels (`shankar0123.docker.scarf.sh/...`) — Scarf-account
    namespace, not a Go import or GitHub repo URL. Stays.

This is a non-blocking, non-customer-impacting change. Operators pulling
container images, running `make verify`, hitting the API, or installing the
agent see no functional difference. Only Go-tooling consumers (none today)
are affected, and they're enabled — not broken — by this commit.

shankar0123 6af95ccf5f notifications: per-policy multi-channel expiry-alert routing
Closes Rank 4 of the 2026-05-03 Infisical deep-research deliverable
(see cowork/infisical-deep-research-results.md Part 5). Pre-fix,
RenewalService.CheckExpiringCertificates already ran daily,
RenewalPolicy.AlertThresholdsDays drove per-cert thresholds, and
NotificationService.SendThresholdAlert deduped per (cert, threshold)
— but the channel was hardcoded to Email
(internal/service/notification.go:118 pre-fix). Operators who
configured PagerDuty / Slack / Teams / OpsGenie via
CERTCTL_PAGERDUTY_ROUTING_KEY etc. got nothing at any threshold
unless SMTP was also wired. Their first signal of an expired cert
was a 3 AM outage.

This commit lands the routing matrix on top of the existing
infrastructure:

  1. RenewalPolicy gains AlertChannels (per-tier channel list) +
     AlertSeverityMap (per-threshold tier assignment) +
     EffectiveAlertChannels / EffectiveAlertSeverity accessors.
     Default*() helpers preserve the back-compat Email-only
     behaviour for operators who haven't touched their policies
     post-upgrade. Migration 000026 adds the JSONB columns
     idempotently.
  2. NotificationService.SendThresholdAlertOnChannel — the new
     per-channel dispatch helper. Old SendThresholdAlert stays as
     an Email-only alias so non-policy callers (admin "send test
     alert" surfaces) keep working byte-for-byte.
  3. NotificationService.HasThresholdNotificationOnChannel — per-
     (cert, threshold, channel) deduplication so a transient
     PagerDuty 5xx today does NOT suppress today's Slack alert and
     tomorrow's PagerDuty retry will still fire.
  4. RenewalService.sendThresholdAlerts walks the resolved channel
     set per threshold tier, fans out to every configured channel,
     handles per-channel failures independently, defensively drops
     off-enum channels with an audit row trail, and records a per-
     channel audit event with metadata.channel + metadata.severity_tier.
  5. service.ExpiryAlertMetrics — atomic counter table mirrored on
     the VaultRenewalMetrics shape from the 2026-05-03 audit fix #5
     (commit ceca364). Three labels: channel × threshold × result
     (success / failure / deduped). Cardinality bound: 6 × 4 × 3 =
     72 series for the standard 4-threshold matrix.
  6. handler.MetricsHandler.SetExpiryAlerts wires the Prometheus
     exposer for certctl_expiry_alerts_total{channel,threshold,result}.
     Pre-sorted snapshot for byte-stable emission.
  7. cmd/server/main.go threads ONE service.ExpiryAlertMetrics
     instance through both the recording side (notificationService.
     SetExpiryAlertMetrics) and the exposing side
     (metricsHandler.SetExpiryAlerts).

Dispatch flow (post-fix, per renewal-loop tick):

  cert ages past T-30  → daily renewal-loop fires
                       → policy lookup
                       → for each crossed threshold:
                           - resolve severity tier (informational/
                             warning/critical) via AlertSeverityMap
                           - look up channel set in AlertChannels[tier]
                           - for each channel: dedup → SendThresholdAlertOnChannel
                             → notifierRegistry[channel] → audit row →
                             Prometheus counter increment

Tests (internal/service/renewal_expiry_alerts_test.go):

  TestExpiryAlerts_DefaultMatrix_EmailOnly
  TestExpiryAlerts_PerTierFanOut
  TestExpiryAlerts_PerChannelDedup
  TestExpiryAlerts_OneChannelFails_OthersStillFire
  TestExpiryAlerts_OffEnumChannelDropped
  TestExpiryAlerts_MetricCounterIncrements
  TestExpiryAlerts_NilPolicy_FallsToDefault
  TestExpiryAlerts_OperatorOptOutOfTier

The PerTierFanOut test wires 6 mock notifiers, drives a cert at 0
days through the canonical 4 thresholds with the matrix
{informational:[Slack], warning:[Slack,Email],
critical:[PagerDuty,OpsGenie,Email]}, and asserts the exact
recipient counts: Slack=3, Email=3, PagerDuty=1, OpsGenie=1, no
Teams, no Webhook. The OneChannelFails test pins that PagerDuty
returning a 503 does NOT skip Slack/Email at the same threshold.

Drive-by fix (internal/service/testutil_test.go): the existing
mockNotifRepo.List ignored its filter and returned all rows, which
let legacy tests pass on dedup-via-substring even though the
postgres repo actually applied the filter. Updated the mock to
honour CertificateID / Type / Status / Channel / MessageLike
filters in the same shape as the postgres implementation
(internal/repository/postgres/notification.go). All pre-existing
service tests still pass — the legacy test suite happened to be
robust to the mock filter doing nothing.

Documentation:
  - docs/connectors.md Notifier section gains "Routing expiry
    alerts across channels" — operator-facing, JSON example,
    procurement playbook ("How do I make sure PagerDuty pages on
    the T-1 alert?"), debug recipe via SQL on audit_events +
    notification_events + Prometheus.
  - docs/runbook-expiry-alerts.md — sysadmin-grade flowchart,
    per-policy channel-matrix configuration recipes, "did the on-
    call team get paged?" SQL queries, cardinality budget, V3-Pro
    forward path.
  - cowork/WORKSPACE-ROADMAP.md gains "Multi-channel expiry
    alerts: per-owner routing" V3-Pro entry under Adapter
    hardening.

Out of scope (intentional, flagged in V3-Pro forward path):
  - Per-owner / per-team / per-tenant channel routing (matrix is
    per-policy today, not per-owner).
  - Calendar-aware suppression (no T-30 alerts on weekends).
  - Escalation chains (T-1 unanswered for 30m → escalate).
  - Per-channel rate limiting (downstream of I-005 retry+DLQ).

CHANGELOG.md is intentionally not hand-edited per CHANGELOG.md
itself ("no longer maintains a hand-edited per-version changelog;
per-release notes are auto-generated from commit messages between
consecutive tags").

Verified locally:
- gofmt clean.
- go vet ./internal/domain/... ./internal/service/...
  ./internal/api/handler/... ./cmd/server/...  clean.
  (./internal/repository/postgres/... vet failed on transitive
  testcontainers/docker module download — sandbox disk pressure,

- go test -short -count=1 ./internal/domain/...
  ./internal/service/... ./internal/api/handler/...  green.
- go test -race -count=10 -run 'TestExpiryAlerts'
  ./internal/service/...  green (per-channel dedup race-free).

shankar0123 ceca3647eb vault: add automatic token renewal at TTL/2 + Prometheus metric
Closes Top-10 fix #5 of the 2026-05-03 issuer-coverage audit (see
cowork/issuer-coverage-audit-2026-05-03/RESULTS.md). Pre-fix, the
VaultPKI adapter authenticated with a static token and never called
renew-self. Long-lived deploys hit token expiry; the first
operator-visible signal was failed cert renewals on production
targets.

This commit:

  1. Connector.Start(ctx) spawns a goroutine that calls
     POST /v1/auth/token/renew-self at TTL/2 cadence (computed from a
     one-shot lookup-self at startup). Honours ctx.Done() for
     graceful shutdown via a per-loop done channel + Stop().
  2. On `renewable: false` response (initial lookup OR any subsequent
     renewal), the loop emits a WARN, increments the not_renewable
     counter, and exits. The operator must rotate the token before
     Vault's Max TTL elapses.
  3. New Prometheus counter certctl_vault_token_renewals_total with
     labels result={success,failure,not_renewable}. Registered
     alongside existing certctl_issuance_* counters in
     internal/api/handler/metrics.go.
  4. ERROR-level logging on renewal failure with operator-actionable
     substring ("vault token renewal failed; rotate the token before
     TTL expires") so journalctl + grep find it. Loop keeps ticking
     after a failure — transient blips don't kill it.

New optional issuer.Lifecycle interface:

  type Lifecycle interface {
      Start(ctx context.Context) error
      Stop()
  }

Connectors that hold no background goroutines (almost all of them)
do not implement this — IssuerRegistry.StartLifecycles /
StopLifecycles feature-detect via type assertion. New
lifecycle-bearing connectors plug in by implementing the interface;
no further registry plumbing required.

Wiring (cmd/server/main.go):

  - service.NewVaultRenewalMetrics() instance is shared between
    issuerRegistry.SetVaultRenewalMetrics (so Vault connectors built
    by Rebuild get a recorder) and metricsHandler.SetVaultRenewals
    (so the Prometheus exposer emits the new series).
  - issuerRegistry.StartLifecycles(ctx) is called after
    issuerService.BuildRegistry; defer issuerRegistry.StopLifecycles
    is paired so goroutines exit cleanly on signal.
  - IssuerConnectorAdapter.Underlying() exposes the wrapped
    issuer.Connector so registry-level machinery can reach the
    concrete connector behind the adapter without duplicating the
    wiring at every call site.

Tests (internal/connector/issuer/vault/vault_renew_test.go):

  - TestVault_RenewLoop_TickAtHalfTTL — three ticks → three
    renewals, all "success".
  - TestVault_RenewLoop_StopsOnNotRenewable — second renewal returns
    renewable=false, loop exits, third tick fires no HTTP call.
  - TestVault_RenewLoop_FailureSurfacesViaMetric — first renewal 403
    bumps "failure", second renewal succeeds → loop kept ticking.
  - TestVault_RenewLoop_CtxCancellation_StopsCleanly — Stop returns
    within 200ms after ctx cancel.
  - TestVault_RenewLoop_StartsNothingWhenNotRenewable — token
    already non-renewable at boot ⇒ no goroutine, "not_renewable"
    metric increments at startup so operators see it in Grafana.
  - TestVault_ComputeInterval — 4 cases pinning TTL/2 +
    minRenewInterval floor.
  - TestVault_RenewSelf_ParseFailure_NamesActionableInError —
    surfaced error contains "vault token renewal failed" + "rotate
    the token".

Cadence is dynamic — every successful renewal re-derives TTL/2
from the renewed lease's lease_duration, so a short bootstrap
token that gets renewed up to a longer Max TTL shifts to the
longer cadence automatically (defends against degenerate fast
ticking on a token whose Max TTL is far longer than its initial
TTL).

Documentation:
  - docs/connectors.md Vault PKI section gains "Token TTL +
    automatic renewal" subsection (operator-facing: cadence, metric,
    renewable=false rotation playbook).

Out of scope (intentional, flagged in the audit follow-up):
  - AppRole / Kubernetes / AWS IAM auth methods (different renewal
    semantics).
  - Hot-reload of rotated token from disk (operator restarts
    today; future: GUI/MCP issuer-update path triggers Rebuild
    which Stops the old connector and Starts the new one).
  - Auto-re-auth after token death (operator playbook owns it).

CHANGELOG.md is intentionally not hand-edited (per CHANGELOG.md
itself: "no longer maintains a hand-edited per-version changelog;
per-release notes are auto-generated from commit messages between
consecutive tags").

Verified locally:
- gofmt clean.
- go vet ./internal/service/... ./internal/api/handler/...
  ./internal/connector/issuer/vault/... ./cmd/server/...  clean.
- go test -short -count=1 ./internal/connector/issuer/vault/...
  ./internal/service/... ./internal/api/handler/...  green.
- go test -race -count=10 -run 'TestVault_RenewLoop|TestVault_ComputeInterval'
  ./internal/connector/issuer/vault/...  green.

shankar0123 876b937e47 acme-server: cert-manager integration test + production hardening (Phase 5/7)
Closes the production-readiness loop on the ACME surface. After this
commit, certctl ships per-account rate limits + a GC sweeper for
expired ACME state + a kind-driven cert-manager 1.15 integration test
+ a lego-driven RFC conformance harness + a k6 loadtest scenario for
the unauthenticated ACME path.

Architecture:
  - Rate limits live in-memory + per-replica. Restart wipes the
    counters; orders/hour caps are eventual-consistency anyway. A
    3-replica certctl-server fleet behind an LB effectively has 3x
    the configured throughput per account; persistent rate limiting
    is a follow-up if production telemetry shows abuse patterns we
    can't catch in a single restart cycle. Per-key + per-action
    isolation: ActionNewOrder/acc-1, ActionKeyChange/acc-1, and
    ActionChallengeRespond/<challenge-id> are independent buckets.
  - GC loop follows the existing scheduler-loop pattern (atomic.Bool
    + sync.WaitGroup; see crlGenerationLoop for shape). Three
    independent SQL sweeps per tick (DELETE expired nonces; UPDATE
    pending authzs whose expires_at < now() to expired; UPDATE
    pending/ready/processing orders whose expires_at < now() to
    invalid). Each sweep is a single statement; failures are logged-
    and-continued so a failing nonces sweep doesn't block authzs.
    Per-sweep 1m timeout bounds a stuck Postgres.
  - cert-manager integration test is gated on KIND_AVAILABLE so CI
    skips it cleanly (kind is too heavy for per-PR). Operators run
    locally via 'make acme-cert-manager-test'; the harness brings up
    a fresh cluster each run + tears it down on Cleanup.
  - lego conformance harness drives a real ACME client through
    register → run → cert-PEM-landed against a hermetic certctl
    stack. Catches RFC-shape regressions third-party clients would
    hit before they ship.
  - k6 ACME-flow scenario hammers the unauthenticated surface
    (directory + new-nonce + ARI synthetic-id) at 100 VUs × 5m. JWS-
    signed flows are out of scope for k6 (no JWS support); they're
    covered by the lego harness above.

What ships:
  - internal/api/acme/ratelimit.go (+ ratelimit_test.go: 7 cases —
    disable-when-perHour-zero, capacity, per-key isolation, per-
    action isolation, refill-over-time, RetryAfter, concurrent-access
    with -race + 200 goroutines × 200 calls).
  - internal/repository/postgres/acme.go: 4 new methods —
    CountActiveOrdersByAccount + GCExpiredNonces + GCExpireAuthorizations

shankar0123 397d5665b4 fix: collapse identical if/else branches in Account handler (CodeQL #25)
CodeQL alert #25 (go/duplicate-branches) on internal/api/handler/
acme.go::ACMEHandler.Account flagged that 'if readOnly { ... } else
{ ... }' had byte-identical bodies — both setting the same
Content-Type: application/json header. The 'readOnly' bool was
threaded through the function as a placeholder for differentiated
headers (Cache-Control etc. on the POST-as-GET path) that never
landed; both branches collapsed to the same value with no
follow-through.

Audit + fix:
  - The alert is real (verified by re-reading the source); not a
    false positive.
  - The Copilot Autofix Anthropic surfaced was correct in spirit but
    incomplete: it collapsed the if/else but left 'readOnly' as
    dead code (declared at line 395, assigned at lines 400 and 436,
    only read at the now-removed if). golangci-lint's 'unused'
    linter would flag 'readOnly' next.
  - Complete fix: collapse the if/else AND remove the now-unused
    'readOnly' variable + its 2 assignments. Single unconditional
    'w.Header().Set("Content-Type", "application/json")' covers
    both paths (RFC 8555 §6.3 POST-as-GET + §7.3.2 / §7.3.6 update
    + deactivation all return the same account JSON shape — no spec
    rationale for differentiating headers).

Verified locally: 'gofmt -l .' clean; 'go vet ./...' clean;
'go test -short -count=1 ./internal/api/handler/' green; 'grep
readOnly' on the file returns only the new explanatory comment
(no live references).

The alert was first detected in commit 27bd660 (Phase 1b) — the
duplicate has been sitting in the codebase since the Account
handler shipped. No functional regression for any RFC 8555 client
(cert-manager, lego, Posh-ACME): same status code, same headers,
same body.

shankar0123 0299e4a852 acme-server: key rollover + revocation + ARI (Phase 4/7)
Closes the RFC 8555 + RFC 9773 surface beyond the issuance happy-path:
  - POST /acme/profile/<id>/key-change   (RFC 8555 §7.3.5)
  - POST /acme/profile/<id>/revoke-cert  (RFC 8555 §7.6)
  - GET  /acme/profile/<id>/renewal-info/<cert-id>  (RFC 9773 ARI)

After this commit, ACME clients can rotate account keys, revoke certs
through the ACME surface (rather than only via the certctl GUI/API),
and fetch ARI for proactive renewal scheduling.

Architecture:
  - Key rollover: outer JWS verified against the registered account key
    (existing kid path); the inner JWS — embedded as the outer's payload
    — verified against the embedded NEW jwk in a new dedicated routine
    (ParseAndVerifyKeyChangeInner) that enforces RFC 8555 §7.3.5
    inner-only invariants: MUST use jwk + MUST NOT use kid, payload
    .account == outer.kid, payload.oldKey thumbprint-equals registered.
    A single WithinTx swaps the stored thumbprint+pem and writes the
    audit row. Concurrent-rollover safety via SELECT…FOR UPDATE on the
    conflicting account row in UpdateAccountJWKWithTx; the loser
    observes the winner's new thumbprint and is told to retry (409).
  - Revocation: two auth paths. kid → AccountOwnsCertificate single-
    indexed COUNT lookup over acme_orders. jwk → constant-time RFC 7638
    thumbprint compare against the cert's pubkey. Both paths route
    through service.RevocationSvc.RevokeCertificateWithActor so the
    existing CRL/OCSP refresh + audit + metrics pipeline applies. RFC
    5280 §5.3.1 numeric reason codes clamp to certctl's
    domain.ValidRevocationReasons; codes 8 (removeFromCRL) + 10
    (aACompromise) clamp to 'unspecified' since they aren't in the set.
  - ARI is GET-only and unauth per RFC 9773 §4. Cert-id wire shape is
    base64url(AKI).base64url(serial); ParseARICertID strict-decodes,
    SerialHex emits the canonical certctl-shape lowercase-no-leading-
    zeros hex used in certificate_versions.serial_number.
    ComputeRenewalWindow has 3 branches: bound RenewalPolicy →
    [notAfter - days, notAfter - days/2]; no policy → last 33% of
    validity; past expiry → [now, now + 1d] (renew immediately).
    Retry-After honors CERTCTL_ACME_SERVER_ARI_POLL_INTERVAL.

What ships:
  - internal/api/acme/{keychange,ari}.go (+ phase4_test.go: 15 tests).
  - internal/api/acme/order.go: RevokeCertRequest wire shape.
  - internal/api/handler/acme.go: KeyChange, RevokeCert, RenewalInfo
    + 11 new writeServiceError mappings.
  - internal/repository/postgres/acme.go: UpdateAccountJWKWithTx (FOR
    UPDATE + expectedOldThumbprint precondition; ErrACMEAccountKey-
    ConcurrentUpdate sentinel) + AccountOwnsCertificate.
  - internal/service/acme.go: RotateAccountKey + RevokeCert +
    RenewalInfo; CertificateRevoker + RenewalPolicyLookup interfaces;
    SetRevocationDelegate + SetRenewalPolicyLookup wiring; 11 new
    sentinels; 6 new metrics.
  - internal/service/acme_phase4_test.go: service-layer tests for
    RotateAccountKey (happy + duplicate-key) + RevokeCert (kid mismatch
    + jwk mismatch + jwk happy + already-revoked + reason-clamping) +
    RenewalInfo (disabled + bad cert-id).
  - internal/api/router/router.go: 6 new register calls (3 per-profile
    + 3 shorthand). Router parity exceptions extended in lockstep
    (in-tree SpecParityExceptions + CI-only openapi-handler-exceptions
    .yaml).
  - cmd/server/main.go: SetRevocationDelegate(revocationSvc) +
    SetRenewalPolicyLookup(renewalPolicyRepo) at startup.
  - internal/config/config.go: CERTCTL_ACME_SERVER_ARI_ENABLED (default
    true) + CERTCTL_ACME_SERVER_ARI_POLL_INTERVAL (default 6h);
    BuildDirectory's ariEnabled flag now flips on under
    cfg.ARIEnabled.
  - docs/acme-server.md: phase status flipped to Phase 4; endpoints
    table grows 6 rows (3 per-profile + 3 shorthand); FAQ section
    appended explaining how to rotate keys, revoke certs, and consume
    ARI.

Tests:
  - 'go vet ./...' clean across the repo.
  - 'go test -short -count=1 ./...' green across every package.
  - phase4_test.go covers: keychange happy-path + 5 negatives +
    MapKeyChangeErrorToProblem coverage; ARI cert-id round-trip + 6
    malformed cases + BuildARICertID from a generated cert; window-
    math 3 branches.
  - service-layer tests confirm: RotateAccountKey atomically swaps the
    thumbprint (verifies persisted state) and rejects duplicate keys;
    RevokeCert routes through the stub RevocationSvc with the right
    actor string + reason on the jwk path, rejects mismatched keys,
    rejects already-revoked certs, clamps reason codes correctly;
    RenewalInfo respects ARIEnabled + cert-id format.

shankar0123 7e22204ba7 acme-server: HTTP-01 + DNS-01 + TLS-ALPN-01 challenge validation (Phase 3/7)
Wires up the actual challenge-validation machinery so profiles in
acme_auth_mode='challenge' resolve end-to-end. After this commit,
cert-manager 1.15+ with `solver: http01: ingress` against a
challenge-mode profile completes a real HTTP-01 flow and gets a cert.
DNS-01 + TLS-ALPN-01 share the same code path with the appropriate
validator selection.

Architecture (the load-bearing parts):
  - 3 separate semaphore-bounded worker pools (one per challenge type),
    so HTTP-01 and DNS-01 can't starve each other under load. Default
    weight 10 per type; tunable via CERTCTL_ACME_SERVER_HTTP01_CONCURRENCY,
    DNS01_CONCURRENCY, TLSALPN01_CONCURRENCY.
  - 30s per-challenge timeout (configurable via PoolConfig.PerChallengeTimeout).
  - HTTP-01 validator runs validation.IsReservedIPForDial (newly
    exported wrapper preserving the existing private impl byte-for-byte
    for the network scanner + ValidateSafeURL paths) on the resolved
    IP — both at the initial dial and every redirect hop. SSRF probes
    into private IP space are refused before the connect.
  - DNS-01 validator uses a dedicated resolver pointed at
    CERTCTL_ACME_SERVER_DNS01_RESOLVER (default 8.8.8.8:53) — does
    NOT use the system resolver to keep behavior deterministic across
    deployments. Wildcard handling: `*.example.com` queries
    _acme-challenge.example.com.
  - TLS-ALPN-01 validator (RFC 8737) connects with ALPN `acme-tls/1`,
    inspects the id-pe-acmeIdentifier extension (OID 1.3.6.1.5.5.7.1.31),
    asserts the ASN.1 OCTET STRING value equals SHA-256 of the key
    authorization. Cert chain is intentionally NOT validated
    (InsecureSkipVerify=true is correct per RFC 8737 — the proof is
    in the extension, not the chain). Documented in docs/tls.md L-001
    table + the //nolint:gosec comment carries the justification.
    SSRF guard: same posture as HTTP-01.
  - Validation is asynchronous: handler accepts the POST and returns
    200 immediately with status=processing; the worker-pool fires a
    callback that updates challenge → authz → order in a fresh
    background-context WithinTx. The order auto-promotes to `ready`
    when ALL authzs become valid; auto-fails to `invalid` when ANY
    authz becomes invalid.

What ships:
  - internal/api/acme/challenge.go: KeyAuthorization (RFC 8555 §8.1) +
    DNS01TXTRecordValue (§8.4) + TLSALPN01ExtensionValue (RFC 8737 §3)
    helpers; IDPEAcmeIdentifierOID; ChallengeProblemFromError mapper
    (4-way: connection / dns / tls / incorrectResponse); 9 sentinel
    errors covering every named failure mode.
  - internal/api/acme/validators.go: ChallengeValidator interface;
    Pool dispatcher with 3 semaphores + per-type in-flight + peak
    gauges; HTTP01Validator + DNS01Validator + TLSALPN01Validator
    implementations; Drain method called from cmd/server/main.go's
    shutdown sequence.
  - internal/api/acme/validators_test.go: KeyAuthorization round-trip,
    DNS01 / TLS-ALPN-01 helper tests, SSRF rejection, bounded-
    concurrency saturation test (peak-in-flight ≤ cap), type-isolation
    test (HTTP-01 saturation doesn't block DNS-01), UnknownType test,
    7-case ChallengeProblemFromError mapping.
  - internal/repository/postgres/acme.go: GetChallengeByID +
    UpdateChallengeWithTx + UpdateAuthzStatusWithTx.
  - internal/service/acme.go: SetValidatorPool wires the *acme.Pool;
    RespondToChallenge dispatches with account-ownership assertion +
    KeyAuthorization computation + processing-status transition (atomic
    + audit); recordChallengeOutcome callback persists the final
    challenge + cascading authz + order-promote/-fail in one WithinTx +
    audit row. 4 new metrics.
  - internal/api/handler/acme.go: Challenge handler; round-trips
    account.JWKPEM through ParseJWKFromPEM to recover the *jose.JSONWebKey
    the validator pool needs.
  - internal/api/router/router.go + openapi_parity_test.go +
    api/openapi-handler-exceptions.yaml: 2 new routes (per-profile +
    shorthand for challenge/{chall_id}) with parity exceptions.
  - cmd/server/main.go: constructs the Pool at startup with the
    per-type concurrency caps from cfg.ACMEServer; ACMEService.ValidatorPool()
    accessor exposed for the shutdown drain sequence.
  - internal/validation/ssrf.go: exported IsReservedIPForDial wrapper
    (private impl unchanged; network scanner + ValidateSafeURL paths
    byte-identical with prior behavior).
  - docs/tls.md: L-001 InsecureSkipVerify table extended with the
    TLS-ALPN-01 validator justification (RFC 8737 §3).
  - docs/acme-server.md: phase status updated; endpoints table grows
    the challenge row; phases-cross-reference flips Phase 3 → live.

Tests:
  - 80%+ coverage on the new files.
  - BoundedConcurrency test: 10 challenges submitted against an
    HTTP-01 pool of weight 3; observed peak-in-flight ≤ 3, all 10
    eventually complete, post-Drain in-flight returns to 0.
  - TypeIsolation test: HTTP-01 saturation does NOT block a DNS-01
    submission; DNS-01 callback fires within 2s.
  - SSRF rejection test: a Validate against `localhost` is refused
    before the dial (ErrChallengeReservedIP or ErrChallengeConnection).

shankar0123 4ee486edcb acme-server: orders + authorizations + finalize + cert download (Phase 2/7)
Closes the issuance loop in trust_authenticated mode (commits e146b00
+ 27bd660 wired the foundation + JWS-verified account resource).
After this commit, an ACME client running against a profile with
acme_auth_mode='trust_authenticated' end-to-end-issues a real cert:

  POST /acme/profile/<id>/new-order      → 201 + order URL (status=ready)
  POST /acme/profile/<id>/order/<oid>    → POST-as-GET fetch
  POST /acme/profile/<id>/order/<oid>/finalize  → 200 + status=valid + cert URL
  POST /acme/profile/<id>/cert/<cid>     → 200 + PEM chain

Profiles with acme_auth_mode='challenge' get the same code path with
authz/challenge rows in `pending` state until Phase 3's validators
wire up. The mode is read from the bound profile's column at request
time, NOT cached at server start — operators flipping the column via
SQL take effect on the next order without restart.

Architecture (the load-bearing part):
  - Finalize routes through service.CertificateService.Create — the
    canonical certctl issuance entry point that wraps the
    managed_certificates row insert + audit row in s.tx.WithinTx.
    RenewalPolicy / CertificateProfile / per-issuer-type Prometheus
    metrics / audit rows all apply uniformly to ACME-issued certs via
    the same code path that already serves EST/SCEP/agent/REST issuance.
  - Identifier validation runs BEFORE order creation. Rejected
    identifiers return RFC 7807 with per-identifier subproblems and
    create no order row.
  - Source stamp on managed_certificates: domain.CertificateSourceACME.
    Operators bulk-revoke ACME-issued certs by filtering on Source=ACME.
  - 3-step atomicity boundary documented in code + this commit msg:
    (A) WithinTx-A marks order processing + audit row.
    (B) IssuerConnector.IssueCertificate + CertificateService.Create
        (each in its own WithinTx — Create wraps cert row + audit
        atomically).
    (C) WithinTx-C creates certificate_versions row + transitions order
        to valid + sets certificate_id + audit row.
    The brief window between B and C can leave a managed_certificates
    row whose order is still in `processing`. Phase 5's GC scheduler
    reconciles. Documented inline.

What ships:
  - internal/api/acme/order.go: OrderResponseJSON + AuthorizationResponseJSON
    + ChallengeResponseJSON + NewOrderRequest + FinalizeRequest wire
    shapes; ValidateIdentifiers (Phase 2 syntactic checks, dns-only);
    CSRMatchesIdentifiers (RFC 8555 §7.4 strict equality, case-folded).
  - internal/domain/acme.go: ACMEOrder + ACMEAuthorization + ACMEChallenge
    + ACMEIdentifier + ACMEProblem domain types + closed status enums
    for each (order: pending|ready|processing|valid|invalid; authz:
    pending|valid|invalid|deactivated|expired|revoked; challenge:
    pending|processing|valid|invalid; challenge type: http-01|dns-01|
    tls-alpn-01).
  - internal/domain/profile.go: new ACMEAuthMode field reading from
    certificate_profiles.acme_auth_mode (added in migration 25).
  - internal/domain/certificate.go: new CertificateSourceACME enum value.
  - internal/repository/postgres/profile.go: extended SELECT/scanProfile
    to read the per-profile acme_auth_mode column with a COALESCE
    default of trust_authenticated.
  - internal/repository/postgres/acme.go: full order/authz/challenge
    CRUD (CreateOrderWithTx + GetOrderByID + UpdateOrderWithTx +
    CreateAuthzWithTx + GetAuthzByID + ListAuthzsByOrder +
    ListChallengesByAuthz + CreateChallengeWithTx) with proper
    sql.NullTime + JSONB handling. scanACMEOrder /
    scanACMEAuthz / scanACMEChallenge helpers.
  - internal/service/acme.go: extended ACMERepo interface; new
    SetIssuancePipeline wires certificateService + certificateRepo +
    issuerRegistry. CreateOrder (auth-mode-dispatched: trust_authenticated
    auto-marks order ready + authz valid + 1 placeholder http-01
    challenge valid; challenge mode keeps everything pending). LookupOrder
    (with account-ownership assertion). LookupAuthz. ListAuthzsByOrder.
    FinalizeOrder (3-step atomicity boundary as above; CSR-vs-order
    SAN strict-equality check before issuance; persists FinalizeOrderResult
    {Order, CertID}). LookupCertificate. randIDSuffix + base32encode
    helpers for the human-readable acme-ord-* / acme-authz-* /
    acme-chall-* prefixes (CLAUDE.md "TEXT primary keys with human-
    readable prefixes" architecture decision). 8 new per-op metrics.
  - internal/service/acme_test.go: extended fakeACMERepo with Phase 2
    interface stubs; new orderTrackingRepo for observable persistence;
    2 new tests asserting trust_authenticated → auto-ready/valid and
    challenge → stays-pending.
  - internal/api/handler/acme.go: NewOrder + Order + OrderFinalize +
    Authz + Cert handler methods. orderURL / authzURL / certURL /
    challengeURLBuilder helpers; marshalOrderForResponse fetches
    per-order authzs to populate the URL list. parseOptionalTime for
    notBefore / notAfter.
  - internal/api/handler/acme_handler_test.go: extended mockACMEService
    with Phase 2 method stubs; 4 new handler tests (NewOrder happy +
    rejected-identifier + OrderFinalize bad-CSR + Cert happy).
  - internal/api/router/router.go: 10 new Register calls (5 per-profile
    + 5 shorthand) for new-order, order/{ord_id}, order/{ord_id}/finalize,
    authz/{authz_id}, cert/{cert_id}.
  - internal/api/router/openapi_parity_test.go + api/openapi-handler-exceptions.yaml:
    10 new exception entries.
  - cmd/server/main.go: SetIssuancePipeline at startup, threading
    certificateService + certificateRepo + issuerRegistry into ACMEService.
  - docs/acme-server.md: phase status updated; endpoints table grows
    5 rows for new-order/order/finalize/authz/cert (per-profile +
    shorthand variants); new section "Finalize routing through
    CertificateService.Create" documenting the 3-step atomicity
    boundary + the actor-string convention `acme:<account-id>`.

Tests: ACME package + service + handler + router + config + domain
all green under -short. New cases:
  - TestCreateOrder_TrustAuthenticated_AutoReady (asserts auto-ready
    transition + valid-status authz/challenge + audit row + metric bump).
  - TestCreateOrder_ChallengeMode_StaysPending (asserts pending-status
    cascading authz/challenge for challenge mode).
  - TestACMEHandler_NewOrder_HappyPath (asserts 201 + Location +
    finalize URL shape).
  - TestACMEHandler_NewOrder_RejectedIdentifier (asserts 400 + RFC 7807
    rejectedIdentifier + per-identifier subproblems for type=ip).
  - TestACMEHandler_OrderFinalize_BadCSR (asserts 400 + badCSR for
    non-base64 CSR field).
  - TestACMEHandler_Cert_HappyPath (asserts 200 + PEM content-type +
    PEM chain in body).

shankar0123 27bd660e49 acme-server: account resource + JWS verifier (Phase 1b/7)
Layers JWS-authenticated POST machinery onto the Phase 1a foundation
(commit e146b00). After this commit, an ACME client can run

  POST /acme/profile/<id>/new-account

against certctl and successfully register an account. Account update
+ deactivation via POST /acme/profile/<id>/account/<acc-id> work.
Orders + challenges remain Phase 2 / 3.

Background:
  Two prior dispatch attempts at the original Phase 1 ("skeleton +
  directory + new-nonce + new-account" as a single commit) failed on
  go-jose v4 API speculation (jws.GetPayload, sig.Algorithm,
  jose.SHA256, etc. — none of those exist in v4). Splitting Phase 1
  into 1a (foundation, no go-jose) and 1b (this commit, all go-jose
  in one place) concentrated the JWS work where attention pays off.
  The verifier reads the actual go-jose v4 surface — ParseSigned with
  closed alg allow-list, Header struct fields (Algorithm, KeyID,
  JSONWebKey, Nonce, ExtraHeaders[HeaderKey]), JWK.Thumbprint with
  stdlib crypto.SHA256.

What ships:
  - internal/api/acme/jws.go: 487-line verifier + sentinel error
    family. Enforces RFC 8555 §6.2 + §6.4 + §6.5 invariants:
      - alg in {RS256, ES256, EdDSA} (closed allow-list passed to
        jose.ParseSigned — HS256 / none / etc. rejected at parse time)
      - exactly one of `kid` / `jwk` in protected header (per
        endpoint policy — new-account demands jwk, others demand kid)
      - protected `url` matches request URL exactly
      - protected `nonce` consumed against acme_nonces (badNonce on
        miss/replay/expiry per RFC 8555 §6.5.1)
      - kid round-trips against canonical AccountKID(accountID) URL
        (catches cross-profile / cross-host replay)
      - kid path: account exists + status=valid (deactivated /
        revoked accounts cannot authenticate)
      - signature verifies; post-Verify payload bytes equal
        UnsafePayloadWithoutVerification (defense in depth)
    + JWK persistence helpers (JWKToPEM / ParseJWKFromPEM round-
    trip a public-only JWK as a PEM-wrapped JSON envelope; stored
    as TEXT in acme_accounts.jwk_pem for diff-friendliness) +
    JWKThumbprint per RFC 7638.
  - internal/api/acme/jws_test.go: 16 cases covering happy paths
    (RS256 kid, ES256 jwk, EdDSA kid) + every named failure mode
    (alg-not-allowed, bad-sig, missing-nonce, unknown-nonce,
    replay, url-mismatch, mixed kid+jwk, deactivated-account,
    cross-host kid). Uses real keypairs + real go-jose Signer to
    build JWS objects.
  - internal/api/acme/account.go: NewAccountRequest /
    AccountUpdateRequest payload shapes (RFC 8555 §7.3 + §7.3.2 +
    §7.3.6) + AccountResponseJSON wire shape + MarshalAccount
    helper.
  - internal/domain/acme.go: ACMEAccount struct + ACMEAccountStatus
    closed enum (valid / deactivated / revoked).
  - internal/repository/postgres/acme.go: full account CRUD path
    (CreateAccountWithTx with 23505-unique-violation sentinel
    translation, GetAccountByID, GetAccountByThumbprint,
    UpdateAccountContactWithTx, UpdateAccountStatusWithTx) +
    sql.ErrNoRows-wrapped repository.ErrNotFound on lookup misses.
  - internal/service/acme.go: ACMERepo interface extended;
    SetTransactor + SetAuditService wires; NewAccount (idempotent
    re-registration per RFC 8555 §7.3.1 — same JWK returns existing
    row without an update or new audit event); LookupAccount;
    UpdateAccount; DeactivateAccount; VerifyJWS adapter that bridges
    api/acme.VerifierConfig to the service-layer ACMERepo; per-op
    metrics extended (new_account_total + _failures_total +
    _idempotent_total + update_account_total + _failures_total +
    deactivate_account_total).
  - internal/service/acme_test.go: 8 new tests covering
    new-account happy path / idempotent re-registration / only-
    return-existing match + no-match / contact update / deactivate
    / lookup-not-found / requires-transactor.
  - internal/api/handler/acme.go: NewAccount + Account handlers.
    Account dispatches POST-as-GET (RFC 8555 §6.3 — empty body or
    {} payload returns the account row), contact update, and
    deactivation from the same endpoint. Defense-in-depth check
    that the kid path-segment matches the URL path-segment (the
    verifier already round-tripped the kid against canonical URL,
    but the handler re-asserts to catch any future verifier
    refactor).
  - internal/api/handler/acme_handler_test.go: 7 new cases
    covering happy-create, idempotent-200, only-return-existing-
    no-match-400, malformed-JWS-400, kid-URL-mismatch-401,
    deactivate, contact-update, POST-as-GET.
  - internal/api/router/router.go: 4 new Register calls (per-
    profile + shorthand for new-account and account/{acc_id}).
  - internal/api/router/openapi_parity_test.go: SpecParityExceptions
    extended with the 4 new routes (RFC 8555 wire-protocol surface,
    not OpenAPI-shaped — same precedent as Phase 1a).
  - cmd/server/main.go: SetTransactor + SetAuditService on
    acmeService at startup so the WithinTx-based new-account /
    update / deactivate paths run with the same transactor instance
    shared across CertificateService / RevocationSvc / RenewalService.
  - docs/acme-server.md: Phase status updated; endpoints table grows
    new-account + account/<acc_id> rows; new "JWS verification
    (Phase 1b)" section enumerates the 7 invariants the verifier
    enforces; phases-cross-reference table marks 1b live.
  - go.mod / go.sum: github.com/go-jose/go-jose/v4 v4.0.4 added.

Atomicity: every account-state mutation writes its acme_accounts row
+ its audit_events row inside one repository.Transactor.WithinTx
call — the canonical certctl atomicity contract (matches
CertificateService.Create at internal/service/certificate.go:131).
Idempotent re-registration explicitly does NOT write an audit row
(RFC 8555 §7.3.1 returns the existing row unmodified).

Tests: 16 jws_test.go cases + 11 service tests + 11 handler tests
all pass under -short. Bad-signature test uses a real registered
account whose stored JWK is a different keypair from the signer's,
so the JWS parses cleanly but jose.Verify rejects — exercises the
ErrJWSSignatureInvalid path directly.

shankar0123 e146b00f0e acme-server: foundation — directory + new-nonce + per-profile routing (Phase 1a/7)
First slice of the RFC 8555 ACME server endpoint (master plan at
cowork/acme-server-endpoint-prompt.md, per-phase prompts at
cowork/acme-server-prompts/). This commit lands the smallest viable
end-to-end deployable slice: an ACME client running

  curl -sk https://certctl/acme/profile/<id>/directory
  curl -sk -I https://certctl/acme/profile/<id>/new-nonce

successfully fetches the directory document and a Replay-Nonce.
Account creation, JWS verification, orders, challenges, and
revocation are all out of scope for this phase and arrive in Phases
1b–4.

Closes the Rank 1 LHF from the 2026-05-03 Infisical deep-research
(cowork/infisical-deep-research-results.md). Pre-fix, certctl was an
ACME consumer only — no /acme/directory endpoint, no JWS verifier,
no challenge validators. K8s customers running cert-manager could
not point at certctl as an ACME issuer; they had to deploy a certctl
agent on every node.

What ships:
  - internal/api/acme/{directory,nonce,errors}.go (+ tests).
  - internal/api/handler/acme.go + acme_handler_test.go.
  - internal/repository/postgres/acme.go (nonce ops only — Phase 1b
    extends with account CRUD; Phases 2-4 extend with order / authz /
    challenge CRUD).
  - internal/service/acme.go (BuildDirectory + IssueNonce stubs;
    Phase 1b adds VerifyJWS / NewAccount / etc.).
  - migrations/000025_acme_server.{up,down}.sql ships the full 5-table
    ACME schema (acme_accounts / acme_orders / acme_authorizations /
    acme_challenges / acme_nonces) PLUS the per-profile
    certificate_profiles.acme_auth_mode column. Phase 1a actively
    uses only acme_nonces; remaining tables are empty until Phases
    1b-4 plug in.
  - internal/config/config.go: ACMEServerConfig struct + ACMEServer
    field on Config. Env vars use CERTCTL_ACME_SERVER_* prefix to
    avoid colliding with the existing consumer-side ACMEConfig at
    config.go:1746 (CERTCTL_ACME_DIRECTORY_URL / PROFILE /
    CHALLENGE_TYPE etc.). Phase 1a wires Enabled +
    DefaultAuthMode + DefaultProfileID + NonceTTL + DirectoryMeta;
    Order/Authz TTLs + per-challenge-type concurrency caps + DNS01
    resolver are reserved fields parsed in 1a so operators can set
    them ahead of Phases 2/3.
  - cmd/server/main.go: wire ACMEHandler into the HandlerRegistry
    literal alongside the existing certificate / EST / SCEP / etc.
    handlers.
  - internal/api/router/router.go: HandlerRegistry.ACME field + 6
    Register calls (3 per-profile + 3 shorthand).
  - internal/api/router/openapi_parity_test.go: 6 new entries in
    SpecParityExceptions. ACME is a wire-protocol surface (JWS-signed
    JSON over HTTPS per RFC 7515) whose semantics are dictated by
    RFC 8555 + RFC 9773 rather than by an OpenAPI document, same
    precedent as SCEP/EST. The canonical reference is
    docs/acme-server.md.
  - docs/acme-server.md: Phase-1a-shaped reference. Configuration
    table for every CERTCTL_ACME_SERVER_* env var. Per-profile
    auth-mode decision tree skeleton. TLS trust bootstrap section
    flagging cert-manager's ClusterIssuer.spec.acme.caBundle
    requirement (the single biggest first-time-deploy footgun;
    the full cert-manager walkthrough lands in Phase 6 but the
    requirement is documented up front).

Architecture decisions baked in:
  - URL family is /acme/profile/<id>/* (per-profile, canonical) with
    /acme/* shorthand active when CERTCTL_ACME_SERVER_DEFAULT_PROFILE_ID
    is set. Path matches existing per-profile precedent in EST + SCEP.
  - Auth mode is per-profile (acme_auth_mode column on
    certificate_profiles), NOT server-wide. One certctl-server can
    serve trust_authenticated for an internal-PKI profile and
    challenge for a public-trust-style profile simultaneously. The
    column is read at request time, not cached at server start —
    operators flipping a profile's mode via SQL take effect on the
    next order without restart.
  - Nonces are DB-backed (acme_nonces table). Survive server restart.
    The RFC 8555 §6.5 replay defense requires the store to outlast
    the client's nonce caching window; an in-memory-only nonce
    store would lose every in-flight order on restart.
  - Per-op atomic counters on service.ACMEService.Metrics() —
    certctl_acme_directory_total, certctl_acme_directory_failures_total,
    certctl_acme_new_nonce_total, certctl_acme_new_nonce_failures_total.
    Naming follows certctl frozen decision 0.10 cardinality discipline.
    Phase 1b will extend with new_account counters; Phase 2 with
    order / finalize / cert; Phase 3 with per-challenge-type counters.

Audit fixes #11 + #12 (cowork/acme-server-prompts/audit-additions.md)
applied:
  - #11: CERTCTL_ACME_SERVER_* prefix avoids the consumer-side
    CERTCTL_ACME_* namespace collision.
  - #12: prior-attempt WIP from two failed Phase-1 dispatches was
    discarded at phase start; this commit starts from a clean tree.

Tests:
  - 14 unit tests in internal/api/acme/ (directory, nonce, errors).
  - 7 handler-level tests via httptest.NewServer + mockACMEService
    (mirrors the mockSCEPService pattern at scep_handler_test.go).
  - 7 service-layer tests with mocked repo + injected profileLookup.
  - All pass under -race -count=1 -short.

Deferred to Phase 1b:
  - JWS verification (go-jose v4 — see master-prompt §8a for the API
    surface and audit doc for the speculation pitfalls).
  - new-account / account/<id> endpoints + AccountService.
  - Nonce *consumption* path (issue path is in this commit; consume
    is only invoked by JWS-verified POSTs which Phase 1b adds).

shankar0123 95c2bf9818 metrics: add per-issuer-type issuance counters, histogram, and failure classifier
Closes the #4 acquisition-readiness blocker from the 2026-05-01 issuer
coverage audit. Before this commit, certctl's Prometheus exposition had
zero per-issuer-type signal — operators answering "is DigiCert slow?"
or "is Sectigo failing more than ACME?" had to grep logs by issuer
name. This commit adds three series labelled by issuer type:

  certctl_issuance_total{issuer_type, outcome}
  certctl_issuance_duration_seconds{issuer_type}            (histogram)
  certctl_issuance_failures_total{issuer_type, error_class}

The histogram covers 0.05–120 second buckets to span the local-issuer
fast path and async-CA slow path (DigiCert/Sectigo/Entrust polling
can take minutes). error_class is a closed enum of eight values
(timeout, auth, rate_limited, validation, upstream_5xx, upstream_4xx,
network, other) classified once in service.ClassifyError. Cardinality
budget is ~276 new series, well within Prometheus's comfortable range.

Implementation:
- service.IssuanceMetrics is the thread-safe counter + histogram
  table. Three independent views (counters / failures / durations)
  exposed via SnapshotCounters / SnapshotFailures / SnapshotDurations.
  sync.RWMutex protects the map shape; per-key sync/atomic.Uint64
  primitives keep the recording hot path lock-free under concurrent
  service-layer goroutines.
- service.IssuanceCounterEntry / IssuanceFailureEntry /
  IssuanceDurationEntry / IssuanceMetricsSnapshotter live in service
  (not handler) to avoid an import cycle: handler already imports
  service for admin_est.go etc., so service can't import handler back.
  Handler's exposer takes the snapshotter via the service-defined
  interface.
- service.ClassifyError pure function maps error → error_class.
  context.DeadlineExceeded / context.Canceled → timeout; *net.OpError
  → network; substring matches against canonical AWS / DigiCert /
  Sectigo error shapes for auth / rate_limited / validation /
  upstream_5xx / upstream_4xx / network; unknown → other. Each branch
  has at least one representative test case in
  TestClassifyError.
- IssuerConnectorAdapter.SetMetrics wires per-adapter recording
  (issuerType + metrics). Existing 28+ test call sites of
  NewIssuerConnectorAdapter keep their one-arg signature; production
  wiring goes through SetMetrics post-construction.
- IssuerRegistry.SetIssuanceMetrics + Rebuild type-asserts to
  *IssuerConnectorAdapter and calls SetMetrics with the issuer type
  string. nil-guarded — tests that hand-build adapters without
  metrics get no-op recording.
- IssuerConnectorAdapter.IssueCertificate / RenewCertificate wrap the
  underlying connector call with start := time.Now() and
  recordIssuance(start, err). Renewal is recorded into the same
  certctl_issuance_* series as initial issuance — operationally,
  renewal IS issuance from the connector's perspective (matches the
  audit prompt's guidance on series naming).
- handler/metrics.go GetPrometheusMetrics gains a new exposer block
  emitting all three series in stable label order with correct
  Prometheus format (_bucket / _sum / _count for the histogram, +Inf
  bucket appended). Sorted via sort.Slice for stable output. nil-
  guarded so deploys without the wire produce clean exposition.
- formatLE helper trims trailing zeros from histogram bucket labels
  via strconv.FormatFloat(le, 'f', -1, 64) so the `le` labels match
  Prometheus client conventions ("0.05", "30", "120", not "0.0500"
  etc.).
- cmd/server/main.go wires a single IssuanceMetrics instance into
  both the IssuerRegistry (recording) and the MetricsHandler (exposer)
  using DefaultIssuanceBucketBoundaries.

Tests:
- TestIssuanceMetrics_RecordAndSnapshot — happy-path counter +
  histogram + failure recording, BucketBoundaries returns a copy
  (not shared storage).
- TestIssuanceMetrics_HistogramCumulative — pins the cumulative-buckets
  contract. 100ms observation lands in 0.1 bucket and every larger
  bucket; 750ms only in the 1.0 bucket. Off-by-one here would
  corrupt every quantile query downstream.
- TestIssuanceMetrics_Concurrency — 100 goroutines × 1000 ops under
  the race detector. Asserts atomic counter integrity across
  contended writes.
- TestClassifyError — 17 cases covering every branch of the closed
  enum plus the nil-error special case.

Implementation chooses the existing hand-rolled fmt.Fprintf
exposition pattern (no prometheus/client_golang dependency added)
to stay consistent with the OCSP / deploy counter blocks already in
the file.

Out of scope (separate follow-ups):
- Revocation metrics (certctl_revocation_*) — symmetric to issuance
  but the audit didn't ask; explicit follow-up commit.
- Discovery / health-check duration histograms.
- prometheus/client_golang migration.

shankar0123 b9d15c5dbf repo,service: introduce WithinTx and atomic audit rows for issue/renew/revoke
Closes the #3 acquisition-readiness blocker from the 2026-05-01 issuer
coverage audit (Part 1.5 finding #1: audit row not transactional with
issuance). AuditRepository.Create previously ran on the package-level
*sql.DB while the certificate insert / version insert / revocation
insert ran on independent connections — a failed audit INSERT after
a successful operation INSERT was silently lost. SOX §404 over IT
general controls, PCI-DSS §10 audit logging, HIPAA §164.312(b) audit
controls, and CA/B Forum Baseline Requirements §5.4.1 audit log
records all presume audit-with-operation atomicity.

Design — Option A (Querier abstraction). The chosen pattern: a shared
repository.Querier interface (subset of *sql.DB and *sql.Tx) plus a
postgres.WithinTx helper that begins a tx, runs fn, commits on nil
error, rolls back on error or panic, and returns the wrapped result.
Repository methods that participate in a service-layer transaction
expose a *WithTx variant taking repository.Querier; the bare methods
remain for stand-alone use. A repository.Transactor abstracts the
"begin tx, run fn, commit/rollback" lifecycle so service-layer code
runs multi-write operations atomically without holding *sql.DB
directly. Option B (UnitOfWork) was considered but adds boilerplate
without behavioral benefit for the current scope. Option C
(context-carried tx) was explicitly rejected — it hides the
transactional boundary from the type system, reproducing the class
of bug we're fixing.

This commit:
- Adds internal/repository/querier.go with the Querier interface
  (compile-time guards that *sql.DB and *sql.Tx satisfy it) and the
  Transactor interface for service-layer use.
- Adds internal/repository/postgres/tx.go with the WithinTx helper
  (begin/fn/commit/rollback with panic recovery) and a transactor
  type that satisfies repository.Transactor.
- Adds CreateWithTx variants on AuditRepository, CertificateRepository
  (Create + Update + CreateVersion), and RevocationRepository.
  Existing bare methods now delegate to the *WithTx variant using
  the package-level *sql.DB so existing call sites are
  behavior-preserving.
- Updates repository/interfaces.go: AuditRepository, CertificateRepository,
  and RevocationRepository declare the new *WithTx methods. Adds an
  atomicity contract doc-comment on AuditRepository pointing at
  WithinTx + the audit blocker.
- Adds AuditService.RecordEventWithTx, mirroring RecordEvent but
  routing through CreateWithTx so the audit row is part of the
  caller's transaction. Same redaction + marshalling contract.
- Refactors three audit-emitting service paths to use Transactor.WithinTx
  when SetTransactor was wired, with a legacy fallback for backward
  compat:
    * CertificateService.Create — cert insert + audit row in one tx.
    * RevocationSvc.RevokeCertificateWithActor — cert status update +
      revocation row + audit row in one tx. The OCSP cache invalidate
      remains best-effort (out of scope per the prompt).
    * RenewalService CompleteServerRenewal — cert version insert +
      cert update + audit row in one tx. Job status update stays
      outside the audit-atomicity scope (job state lives outside
      the operator-facing audit trail).
- Adds SetTransactor on CertificateService, RevocationSvc, and
  RenewalService. cmd/server/main.go wires a single Transactor
  instance shared across all three so all audit-emitting paths run
  their writes in transactions backed by the same *sql.DB handle.
- Updates 5 mock implementations to satisfy the new interface methods:
  mockCertRepo (testutil_test.go), mockCertRepoWithGetError
  (shortlived_test.go), fakeRevocationRepo (crl_cache_test.go),
  intuneE2EAuditRepo (scep_intune_e2e_test.go), and the integration-
  test mocks (lifecycle_test.go: mockCertificateRepository,
  mockAuditRepository, mockRevocationRepository). All *WithTx mocks
  ignore the Querier and delegate to the bare method (mocks have no
  DB; in-memory state is shared regardless of "tx").
- Adds a service-layer test mockTransactor with BeginTxErr and
  CommitErr knobs so the atomic-audit tests can assert error
  propagation through the transactional boundary.
- Adds internal/repository/postgres/tx_test.go: unit-level test that
  WithinTx surfaces "begin tx" wrap when BeginTx fails, and that
  Transactor.WithinTx delegates correctly. Real-Postgres rollback
  semantics are covered by the testcontainers tests in the postgres
  package — sandbox disk pressure prevented adding a sqlmock dep
  for the in-fn / commit-failure unit test, so those scenarios are
  exercised through atomic_audit_test.go using the mockTransactor's
  CommitErr / BeginTxErr fields.
- Adds internal/service/atomic_audit_test.go:
    * TestCertificateService_Create_AtomicWithTx — asserts audit
      insert failure inside the tx surfaces as the operation's error
      (closes the blocker contract).
    * TestCertificateService_Create_LegacyPathLogs — pins the
      backward-compat behavior when SetTransactor isn't wired:
      audit failure is logged-not-failed, matching pre-fix.
    * TestCertificateService_Create_TransactorBeginFailure — BeginTx
      error path: operation fails, no cert insert, no audit insert.
    * TestCertificateService_Create_TransactorCommitFailure —
      Commit error after successful in-fn writes surfaces as the
      operation's error. Real Postgres can fail Commit on
      serialization conflicts; the service must report this.

Out of scope (separate follow-up commits, same shape):
- Issuer CRUD audit atomicity.
- Target CRUD audit atomicity.
- Agent retire (already transactional via RetireAgentWithCascade;
  verified, not changed).
- Renewal-policy CRUD audit atomicity.
- Owner/team/agent-group CRUD audit atomicity.
- Discovery / health-check audit atomicity.

shankar0123 482c7e8047 chore(fmt): repo-wide gofmt -w sweep — close drift surfaced by ci-pipeline-cleanup Phase 4
Mechanical reformat. The new 'gofmt drift' CI step (added in
ci-pipeline-cleanup Phase 4, commit 71b2245) surfaced 111 files
with accumulated gofmt drift across cmd/, internal/, and deploy/test/.

Each file's diff is gofmt-standard: whitespace adjustments, intra-
group import sorting (alphabetical by import path within blank-line-
separated groups), and struct-tag column alignment. No semantic
changes — verified via 'git diff --ignore-all-space' which shows only
the line-position deltas from import reordering.

The gate stays in place after this commit. Going forward it catches
gofmt drift at PR time.

claude 188a41774a chore: gofmt fixes across deploy-hardening I new files
Phase 13 verification surfaced gofmt-formatting drift in 6 files
across the bundle's new code:

- internal/api/handler/metrics.go (struct field alignment)
- internal/connector/target/k8ssecret/validate_only_test.go (alignment)
- internal/connector/target/nginx/nginx.go (alignment)
- internal/connector/target/postfix/postfix.go (alignment)
- internal/connector/target/ssh/validate_only_test.go (alignment)
- internal/service/deploy_counters.go (alignment)

Pure mechanical gofmt -w fixes; no behavior changes. CI's
make verify gate (which runs `go fmt ./...`) didn't catch these
because go fmt is more lenient than gofmt -l, but golangci-lint
v2.11.4 + the explicit gofmt step in Phase 13 verification did.

Phase 13 full-matrix verification all green:
- gofmt -l: empty across all bundle-touched files
- go vet ./internal/deploy/... ./internal/connector/target/... ./internal/service/ ./internal/api/handler/ ./cmd/agent/: clean
- golangci-lint v2.11.4 (the version CI runs): 0 issues

claude 7e8c8cadbb feat(metrics): per-target-type deploy counters wired into /metrics/prometheus
Phase 10 of the deploy-hardening I master bundle. Mirrors the
production-hardening-II Phase 8 OCSP-counter pattern. Per frozen
decision 0.9, the metric naming convention is
`certctl_deploy_<area>_total` with target_type + sub-label.

internal/service/deploy_counters.go:
- DeployCounters struct with sync.Map of per-target-type buckets
  (apache, nginx, etc.). Lock-free fast path via sync/atomic
  Uint64 counters; LoadOrStore on first tick.
- 8 sub-counters per target-type bucket:
  - attemptsSuccess / attemptsFailure
  - validateFailures (PreCommit returned error)
  - reloadFailures (PostCommit returned error → rollback ran)
  - postVerifyFails (post-deploy TLS handshake failed)
  - rollbackRestored (rollback succeeded)
  - rollbackAlsoFail (operator-actionable escalation)
  - idempotentSkips (SHA-256 match → no-op deploy)
- Snapshot returns []DeploySnapshot for the Prometheus exposer.

internal/service/deploy_counters_test.go:
- 5 tests: zero-state, per-target-type tick isolation, race-detector
  smoke under concurrent ticks, cross-target bucket isolation,
  snapshot-mutation-doesn't-affect-counter.

internal/api/handler/metrics.go:
- New DeployCounterSnapshotter interface (mirrors CounterSnapshotter
  for the OCSP counters but uses the per-target-type tuple shape).
- New DeploySnapshotEntry struct copying the service-layer shape;
  avoids importing the service package directly so the handler
  stays dependency-light.
- New SetDeployCounters setter on MetricsHandler (mirrors
  SetOCSPCounters wiring).
- Prometheus exposer extended with 6 new metric blocks per frozen
  decision 0.9:
  - certctl_deploy_attempts_total{target_type, result}
  - certctl_deploy_validate_failures_total{target_type}
  - certctl_deploy_reload_failures_total{target_type}
  - certctl_deploy_post_verify_failures_total{target_type}
  - certctl_deploy_rollback_total{target_type, outcome}
  - certctl_deploy_idempotent_skip_total{target_type}
- Output sorted by target_type for stable diffs across requests.

The agent-side wire-up (cmd/agent/main.go ticking counters in the
DeployCertificate dispatch site) is intentionally deferred to a
follow-up commit — Phase 10's load-bearing change is the
infrastructure; per-connector tick wiring is a mechanical follow-on.

Build + go vet clean. go test -count=1 green for service +
handler packages.

Phase 11 next: cross-cutting integration tests at deploy/test/.

shankar0123 efce2363f7 feat(metrics): extend /metrics/prometheus with per-area OCSP counters (Phase 8)
Production hardening II Phase 8 — surface the OCSP per-event counters
shipped in Phase 1+2 through the existing /api/v1/metrics/prometheus
endpoint. Operators now alert on certctl_ocsp_counter_total
{label="rate_limited"} (Phase 3 trip), {label="nonce_malformed"}
(Phase 1 reject), {label="signing_failed"} (issuer connector fails),
etc.

NEW interface CounterSnapshotter (handler/metrics.go) — minimum
surface the Prometheus exposer needs from any per-area counter table:
just Snapshot() map[string]uint64. service.OCSPCounters.Snapshot
(Phase 1) satisfies it; future per-area counters (CRL, cert-export,
EST per-profile, SCEP per-profile, Intune per-profile) plug in the
same way as separate SetXxxCounters setters.

Naming convention per frozen decision 0.10:
  certctl_<area>_counter_total{label="<event>"} <value>

This commit ships only the OCSP block. The remaining areas (CRL,
cert-export, EST, SCEP, Intune) plug in via the same
SetXxxCounters pattern in follow-up commits — the wire-up cost per
area is one new field + one setter + one block of fmt.Fprintf lines.
The bundle's S-1 docs-count guard means we don't claim a specific
total in prose; operators run `curl /api/v1/metrics/prometheus | grep
certctl_` to enumerate.

Wired in cmd/server/main.go: a single shared *service.OCSPCounters
instance is created once and passed to BOTH the
ocspResponseCacheService (so the cache hot path ticks counters) AND
metricsHandler.SetOCSPCounters (so the Prometheus exposer reads
them). Existing dashboard metrics (certctl_certificate_total,
certctl_agent_total, etc.) remain unchanged at the same line offsets
— back-compat preserved.

Pre-commit verification: go build ./... clean; go test -short
-count=1 green for handler/ + service/. The existing
TestGetPrometheusMetrics_Success tests still pass (the new counter
block is additive at the END of the response body, after the
existing dashboard metrics + uptime line).

shankar0123 3efb9d18ff feat(crl): HTTP caching headers (ETag + If-None-Match 304) per RFC 7232 (Phase 4)
Production hardening II Phase 4 — wire RFC 7232 conditional-request
support into GetDERCRL so CDNs and reverse proxies in front of certctl
can serve repeated CRL fetches from edge caches. Saves bandwidth +
removes the per-request DB read on the certctl side when a relying
party honors max-age.

ETag: weak form (W/) per RFC 7232 §2.3 wrapping the first 16 bytes
of SHA-256(DER) — sufficient ID space for the cache layer + leaves
headroom for a future builder that might emit signature randomness
that doesn't change the CRL semantics.

If-None-Match: when the inbound header matches the computed ETag,
short-circuit to 304 Not Modified with no body. Identical inbound
ETag → identical CRL → no need to retransmit the bytes.

Cache-Control: public, max-age=3600, must-revalidate. The 1h max-age
matches the default CRL regen cadence; relying parties that cache
won't re-fetch within the window. must-revalidate forces revalidation
once the window expires (so a stale relying party doesn't keep
returning expired-cache CRLs after the regen tick).

The pre-existing Cache-Control: max-age=3600 is preserved
syntactically (the new line replaces it with the more complete form);
existing relying parties see the same ceiling, just with the addition
of public + must-revalidate hints for downstream caches.

Pre-commit verification: go build ./... clean; go test -short
-count=1 green for handler/. The existing TestGetDERCRL_* tests still
pass — the new headers are additive, the response body is unchanged.

shankar0123 2e653acd7e feat(ratelimit): per-endpoint rate limit on OCSP + cert-export (Phase 3)
Production hardening II Phase 3 — wire the existing
internal/ratelimit/SlidingWindowLimiter into the OCSP and cert-export
handlers. Removes the DoS vector where an unauthenticated relying
party (or compromised admin token) can hammer the responder /
key-export endpoint at unbounded rates.

OCSP: per-source-IP cap. Default 1000 req/min/IP, 50k tracked IPs
(matches the SCEP/Intune replay cache cap). Configurable via
CERTCTL_OCSP_RATE_LIMIT_PER_IP_MIN; zero disables. Source IP comes
from net.SplitHostPort(r.RemoteAddr) — we deliberately do NOT honor
X-Forwarded-For because OCSP is publicly reachable and untrusted
intermediaries could spoof the header to bypass the limit.

On rate-limit trip: respond with the canonical
ocsp.UnauthorizedErrorResponse pre-built blob from x/crypto/ocsp
(status 6 per RFC 6960 §2.3) plus Retry-After: 60. Using the
unauthorized status (instead of TryLater) avoids hand-rolling DER
for a single rejection path; relying parties retry on any non-good
status anyway.

Cert-export: per-actor cap. Default 50 exports/hr/operator.
Configurable via CERTCTL_CERT_EXPORT_RATE_LIMIT_PER_ACTOR_HR; zero
disables. Actor extracted from the X-Actor request header (set by
the auth middleware); falls back to RemoteAddr if empty (defensive).

On rate-limit trip: HTTP 429 + JSON body
{"error":"rate_limit_exceeded","retry_after_seconds":3600} +
Retry-After: 3600.

NEW config fields in internal/config/config.go::SchedulerConfig:
  OCSPRateLimitPerIPMin (default 1000)
  CertExportRateLimitPerActorHr (default 50)

WIRED in cmd/server/main.go: ocspLimiter constructed with the
configured cap, 1m window, 50k map cap; exportLimiter same shape with
1h window. Both wired via SetOCSPRateLimiter / SetExportRateLimiter
on their respective handlers. Existing deploys see no behavior
change unless the env vars are set to non-default values + traffic
exceeds the cap.

Pre-commit verification: go build ./... clean; go test -short
-count=1 green for handler + service + config.

shankar0123 5af14a819c feat(ocsp): RFC 6960 §4.4.1 nonce extension support — echo client nonce in response, reject malformed
Production hardening II Phase 1.

The OCSP responder previously ignored the request's nonce extension
entirely, leaving relying parties vulnerable to replay attacks. RFC
6960 §4.4.1 defines the OPTIONAL id-pkix-ocsp-nonce extension (OID
1.3.6.1.5.5.7.48.1.2): when present in the request, the responder
MUST echo the same value in the response; when absent, no nonce in
the response (back-compat with relying parties that don't send one).

NEW internal/service/ocsp_nonce.go: ParseOCSPRequestNonce walks raw
DER (golang.org/x/crypto/ocsp.Request doesn't expose the request's
extensions field — the library only exposes IssuerNameHash +
IssuerKeyHash + SerialNumber). Returns one of three states:
  - (nil, false, nil) — no nonce extension in request
  - (nonce, true, nil) — well-formed nonce, ≤ MaxOCSPNonceLength (32)
  - (nil, false, ErrOCSPNonceMalformed) — empty or oversized

NEW internal/service/ocsp_counters.go: sync/atomic counter table for
OCSP request lifecycle (request_get/post, request_success/invalid,
nonce_echoed, nonce_malformed, rate_limited, ...). Mirrors the EST/
SCEP counter pattern; Phase 8 wires these into /metrics/prometheus.

CertSrv types extended:
  - internal/connector/issuer/interface.go::OCSPSignRequest gains
    Nonce []byte field.
  - internal/service/renewal.go::OCSPSignRequest (the service-layer
    duplicate used by ca_operations.go) gains the same field.
  - internal/service/issuer_adapter.go bridges the two.

Service path: CAOperationsSvc.GetOCSPResponseWithNonce(ctx, issuerID,
serialHex, nonce) is the new entry point that plumbs the nonce
through every signing site (good / revoked / unknown / short-lived).
The legacy GetOCSPResponse becomes a nil-nonce wrapper for back-
compat — every existing caller (tests, the GET handler) sees no
behavior change.

CertificateService gains the same WithNonce variant; the handler
interface adds it to the contract. MockCertificateService in tests
extended with the new method (delegates to the legacy fn when no
override is set, so existing tests that don't care about the nonce
keep working).

Local issuer's SignOCSPResponse appends the id-pkix-ocsp-nonce
extension (non-Critical per RFC 6960 §4.4) to the response template's
ExtraExtensions when req.Nonce != nil. The extnValue is the nonce
bytes wrapped in an OCTET STRING per RFC 6960 §4.4.1.

POST OCSP handler (HandleOCSPPost):
  - After ocsp.ParseRequest succeeds, calls ParseOCSPRequestNonce on
    the raw body to extract the optional nonce.
  - On ErrOCSPNonceMalformed (empty or > 32 bytes): writes an
    'unauthorized' OCSP response (status 6 per RFC 6960 §2.3) using
    the canonical ocsp.UnauthorizedErrorResponse from x/crypto/ocsp.
    Does NOT echo malicious bytes back.
  - On well-formed nonce: passes it through GetOCSPResponseWithNonce.
  - On no nonce: nil passed through; back-compat preserved.

GET OCSP handler unchanged — the GET form has no body to carry a
nonce extension.

6 new tests in internal/service/ocsp_nonce_test.go pin every
documented failure mode + the 32-byte boundary. The test fixture
builds an OCSPRequest via golang.org/x/crypto/ocsp.CreateRequest then
splices in a [2] EXPLICIT Extensions element by hand (the library
doesn't expose extension construction either).

Pre-commit verification: gofmt clean, go vet clean across affected
packages, go test -short -count=1 green for service/ + handler/ +
connector/issuer/local/. No new env vars introduced (Phase 1 is
always-on per RFC; no operator opt-out).

shankar0123 f52ae0b18c fix(est): plumb context through ESTService.ReloadTrust to satisfy contextcheck
CI golangci-lint v2.11.4 flagged internal/api/handler/admin_est.go:178:
the AdminESTServiceImpl.ReloadTrust method took ctx context.Context but
called svc.ReloadTrust() with no context, then the underlying
ESTService.ReloadTrust used context.Background() internally for the
audit RecordEvent call. That's the contextcheck linter's textbook
'context discarded at boundary' violation.

Fix: change ESTService.ReloadTrust signature to ReloadTrust(ctx
context.Context) and forward the caller-supplied ctx into
auditService.RecordEvent. AdminESTServiceImpl.ReloadTrust now passes
its received ctx through. The HTTP handler already forwards
r.Context() one layer up, so the request-scoped trace identifiers now
flow end-to-end into the audit row instead of being severed at the
service boundary.

Verified locally with golangci-lint v2.11.4 (the same version CI runs)
against ./internal/api/handler/... ./internal/service/... — '0
issues.' All cmd/* binaries build clean, go test -short -count=1
green for both packages.

shankar0123 67fadeb4e6 EST RFC 7030 hardening master bundle Phases 10-11: libest sidecar e2e
+ Cisco IOS quirk fixtures + ManagedCertificate.Source provenance +
EST bulk-revoke endpoint + 13 typed audit action codes.

Phase 10.1 — libest reference-client sidecar:
- deploy/test/libest/Dockerfile: multi-stage Debian-bookworm-slim
  build of Cisco's libest v3.2.0-2 from source (autoconf/automake/
  libtool + libcurl4-openssl-dev + libssl-dev). Runtime stage
  carries only estclient + bash + openssl + ca-certificates so the
  exec surface stays small + predictable.
- docker-compose.test.yml libest-client entry (profiles: [est-e2e])
  with bind mounts for /config/est (test workspace) + /config/certs
  (certctl CA bundle for TLS pinning); IP 10.30.50.9 (10.30.50.8
  was already taken by certctl-agent).
- deploy/test/est/.gitkeep keeps the bind-mount target tracked.

Phase 10.2 — 5 integration tests (//go:build integration) in
deploy/test/est_e2e_test.go:
- TestEST_LibESTClient_Enrollment_Integration (cacerts → simpleenroll
  → cert-shape assertion)
- TestEST_LibESTClient_MTLSEnrollment_Integration (mTLS sibling-route
  cert auth; skip when bootstrap cert absent)
- TestEST_LibESTClient_ServerKeygen_Integration (RFC 7030 §4.4
  multipart; skip when profile gate disabled)
- TestEST_LibESTClient_RateLimited_Integration (4th enroll trips
  per-principal cap, asserts 429-shaped error)
- TestEST_LibESTClient_ChannelBinding_Integration (libest
  --tls-exporter; skip when libest build lacks the flag).
- requireESTSidecar guard skips the suite when the operator forgot
  --profile est-e2e; helpful error message includes the exact
  command to bring the sidecar up.

Phase 10.3 — Cisco IOS quirk fixtures + 3 unit tests in
internal/api/handler/cisco_ios_quirks_test.go:
- testdata/cisco_ios_15x_pem_csr.txt: PEM body sent with
  Content-Type application/x-pem-file. Handler dispatches on
  body-prefix not Content-Type — accepts cleanly.
- testdata/cisco_ios_16x_trailing_newline_csr.txt: extra trailing
  newlines after base64 body. strings.TrimSpace tolerates.
- testdata/cisco_ios_crlf_b64_csr.txt: CRLF-wrapped base64.
  base64.StdEncoding handles CRLF + LF identically.

Phase 11.1 — ManagedCertificate.Source provenance:
- New domain.CertificateSource enum (Unspecified/EST/SCEP/API/Agent).
- Migration 000023_managed_certificates_source.up.sql adds source
  TEXT NOT NULL DEFAULT '' so existing rows scan as
  CertificateSourceUnspecified — back-compat: bulk-revoke filter
  treats empty as "any source".
- Postgres repo Insert/Update/scan paths all wire the new column.

Phase 11.2 — EST bulk-revoke endpoint:
- BulkRevocationCriteria.Source field (Source-only requests rejected
  as too broad — must accompany at least one narrower criterion).
- service.bulk_revocation.resolveCertificates post-filter by Source
  (empty=any, no SQL change so existing CertificateFilter callers
  unaffected).
- New BulkRevocationHandler.BulkRevokeEST method pins Source=EST +
  dispatches; new route POST /api/v1/est/certificates/bulk-revoke
  (M-008 admin-gated). openapi.yaml documented + parity-guard green.

Phase 11.3 — 13 typed audit action codes in
internal/service/est_audit_actions.go:
- est_simple_enroll_success / _failed
- est_simple_reenroll_success / _failed
- est_server_keygen_success / _failed
- est_auth_failed_basic / _mtls / _channel_binding
- est_rate_limited
- est_csr_policy_violation
- est_bulk_revoke
- est_trust_anchor_reloaded
- ESTService.processEnrollment + SimpleServerKeygen + ReloadTrust
  split-emit BOTH the legacy bare action codes (back-compat for the
  GUI activity-tab chip filters that match by exact string +
  existing audit-log analysers) AND the new typed _success / _failed
  variants (operator grep target + per-failure-mode counter).

Tests:
- internal/api/handler/bulk_revocation_est_test.go — 5 cases
  (admin-true happy path pins Source=EST + non-admin 403 +
  empty-criteria 400 + invalid-reason 400 + method-not-allowed).
- internal/service/est_audit_actions_test.go — 5 cases (SimpleEnroll
  legacy+typed emission / SimpleReEnroll typed / IssuerError
  typed-failed / PolicyViolation triple-emit /
  unique-string invariant).

Pre-commit verification (sandbox): gofmt clean, go vet clean
(excluding repository/postgres testcontainers limit), staticcheck
clean across api/handler/api/router/domain/service/deploy/test,
go test -short -count=1 green for every non-postgres Go package +

shankar0123 8bc9f4eed8 EST RFC 7030 hardening master bundle Phases 5-7: end-to-end serverkeygen
+ profile-driven csrattrs + admin observability with per-status
counters + reload-trust endpoint.

Phase 5 — RFC 7030 §4.4 server-driven key generation:
- internal/pkcs7/envelopeddata_builder.go is the inverse of the
  existing parser/decryptor: AES-256-CBC content cipher + RSA PKCS#1
  v1.5 keyTrans + per-call random IV. Round-trip pinned in test
  (BuildEnvelopedData → ParseEnvelopedData → Decrypt returns the
  original plaintext byte-for-byte).
- ESTService.SimpleServerKeygen runs the full §4.4 flow: parse client
  CSR → require RSA pubkey for keyTrans → resolve per-profile
  algorithm (RSA-2048 default; honors AllowedKeyAlgorithms) → in-
  memory keygen → re-build CSR with server pubkey → run existing
  issuer pipeline → marshal PKCS#8 → CMS-EnvelopedData wrap to a
  synthetic recipient cert wrapping the device's CSR-supplied pubkey
  → zeroize plaintext + PKCS#8 bytes → return CertPEM + ChainPEM
  + EncryptedKey. Typed sentinels ErrServerKeygenRequiresKey-
  Encipherment / ErrServerKeygenUnsupportedAlgorithm /
  ErrServerKeygenDisabled.
- ESTHandler.ServerKeygen + ServerKeygenMTLS emit RFC 7030 §4.4.2
  multipart/mixed with random per-response boundary; per-profile
  SetServerKeygenEnabled gate returns 404 when off (defense in depth
  even if the route was registered).
- New routes POST /.well-known/est/[<PathID>/]serverkeygen +
  /.well-known/est-mtls/<PathID>/serverkeygen; openapi.yaml +
  openapi-parity guard updated.

Phase 6 — Real csrattrs implementation:
- New CertificateProfile.RequiredCSRAttributes []string + migration
  000022_certificate_profiles_csrattrs.up.sql. The migration also
  lands the previously-unwired must_staple column (closes the 5.6
  follow-up loop where the field shipped at the domain + service
  layer but the postgres scan/insert/update never persisted it).
- domain.EKUStringToOID + AttributeStringToOID lookup tables: id-kp-*
  EKUs (RFC 5280 §4.2.1.12) + RFC 5280 DN attributes + RFC 2985
  PKCS#10 attributes + Microsoft Intune device-serial OID.
- ESTService.GetCSRAttrs replaces the v2.0.x nil/204 stub with a
  profile-derived SEQUENCE OF OID ASN.1 marshal. Unknown EKU /
  attribute strings dropped + warning-logged so a typo doesn't take
  down the entire endpoint.

Phase 7 — Admin observability + counters + reload-trust:
- internal/service/est_counters.go: estCounterTab (sync/atomic; 12
  named labels) + ESTStatsSnapshot per-profile shape +
  ESTService.Stats(now) zero-allocation accessor + ReloadTrust()
  SIGHUP-equivalent + SetESTAdminMetadata setter.
- Counter ticks wired into processEnrollment + SimpleServerKeygen at
  every success/failure leg.
- internal/api/handler/admin_est.go mirrors AdminSCEPIntune verbatim:
  Profiles + ReloadTrust handlers + AdminESTServiceImpl. Both
  endpoints admin-gated (M-008 triplet pinned + admin_est.go added
  to AdminGatedHandlers).
- New routes GET /api/v1/admin/est/profiles + POST /api/v1/admin/
  est/reload-trust; openapi.yaml documented; openapi-parity guard
  reproduced clean.
- cmd/server/main.go grows estServices map populated by the per-
  profile EST loop + handed to AdminEST. New MTLSTrust() +
  HasMTLSTrust() accessors on ESTHandler so main.go can pull the
  trust holder for the admin-metadata wire-up.
- Per-profile counter isolation regression test
  (internal/service/est_profile_counter_isolation_test.go) proves
  a future shared-counter refactor would fail at compile-time
  pointer-identity check.

Pre-commit verification (sandbox): gofmt clean, go vet clean

shankar0123 34518b2e66 EST RFC 7030 hardening master bundle Phases 2-4: end-to-end mTLS sibling
route + RFC 9266 channel binding + HTTP Basic enrollment-password +
per-source-IP failed-auth limit + per-(CN, sourceIP) sliding-window cap.

Two new shared packages so EST + Intune share infrastructure:
- internal/cms/ — RFC 9266 tls-exporter extractor (ExtractTLSExporter
  with stdlib-panic recovery for synthetic ConnectionStates) +
  CSR-side channel-binding parser via raw TBSCertificationRequestInfo
  walk (the stdlib's csr.Attributes can't represent the OCTET STRING
  binding value), VerifyChannelBinding composite, EmbedChannel-
  BindingAttribute fixture helper, typed sentinel errors for missing
  / mismatch / not-TLS-1.3 mapped to HTTP 400 / 409 / 426 in handler.
- internal/trustanchor/ — extracted from scep/intune/trust_anchor*.go
  so the EST mTLS sibling route + Intune dispatcher share the same
  SIGHUP-reloadable PEM bundle primitive. intune.TrustAnchorHolder
  is now `= trustanchor.Holder` (type alias) + NewTrustAnchorHolder =
  trustanchor.New (function alias) — every existing call site compiles
  unchanged. Intune's LoadTrustAnchor is a thin wrapper over
  trustanchor.LoadBundle. White-box tests moved to the new package.
- internal/ratelimit/ — extracted from scep/intune/rate_limit.go (this
  was Phase 4.1, in the same bundle). intune.PerDeviceRateLimiter
  is now a thin wrapper preserving the (subject, issuer)→key
  composition; EST handler reaches for SlidingWindowLimiter directly.

ESTHandler grew six optional fields wired by per-profile setters
(SetMTLSTrust / SetChannelBindingRequired / SetEnrollmentPassword /
SetSourceIPRateLimiter / SetPerPrincipalRateLimiter / SetLabelForLog)
plus four new mTLS-route methods (CACertsMTLS / SimpleEnrollMTLS /
SimpleReEnrollMTLS / CSRAttrsMTLS); shared internal pipeline
handleEnrollOrReEnroll(reEnroll, viaMTLS) keeps the auth/binding/
rate-limit gates DRY. New router method RegisterESTMTLSHandlers
registers /.well-known/est-mtls/<PathID>/{cacerts,simpleenroll,
simplereenroll,csrattrs}; AuthExemptDispatchPrefixes extends the
no-auth chain to /.well-known/est-mtls.

cmd/server/main.go's EST loop wires per-profile mTLS holder +
channel-binding policy + per-principal limiter + (when EnrollmentPassword
non-empty) Basic + source-IP limiter; new preflightESTMTLSClientCATrust-
Bundle returns *trustanchor.Holder so SIGHUP rotates the EST mTLS
bundle live without restart. SCEP + EST mTLS profiles now share a
single union mtlsUnionPoolForTLS passed to buildServerTLSConfigWithMTLS
(replaces the protocol-specific scepMTLSUnionPoolForTLS); per-handler
re-verify enforces "cert must chain to THIS profile's bundle" so
cross-protocol bleed is blocked at the application layer even though
the TLS layer trusts certs from either pool's union.

Phase 3.3 source-IP failed-Basic limiter defaults: 10 attempts / 1h
/ 50k tracked IPs (no env var; tunable in a follow-up). Phase 4.2
per-principal limiter cap from CERTCTL_EST_PROFILE_<NAME>_RATE_
LIMIT_PER_PRINCIPAL_24H (existing field, Phase 1 shipped).

New tests:
- internal/cms/channelbinding_test.go: extractor + CSR-side parser +
  composite + TLS-1.3 round-trip end-to-end + EmbedChannelBinding-
  Attribute round-trip
- internal/trustanchor/holder_test.go: parseBundlePEM white-box +
  LoadBundle + Holder Get/Pool/SetLabelForLog/Reload-happy/
  Reload-keeps-old-on-failure/Reload-keeps-old-on-expired/
  WatchSIGHUP-reloads-pool/WatchSIGHUP-stop-clean
- internal/api/handler/est_hardening_test.go: 16 named cases covering
  mTLS no-trust-pool 500 + no-cert 401 + cross-profile cert 401 +
  happy-path 200 + CACertsMTLS auth gate + CSRAttrsMTLS auth gate +

Shankar 444942eab8 fix(scep-intune): close 11 audit gaps from 2026-04-29 pre-tag review
Closes the eleven gaps identified in the pre-v2.1.0 audit of the SCEP
RFC 8894 + Intune master bundle (cowork/scep-bundle-gap-closure-prompt.md).
Constitutional rule from cowork/CLAUDE.md::Operating Rules — 'Always
take the complete path, not the easy path' — drove this closure: each
gap was a load-bearing wire that crossed multiple layers (config →
validator → service wire-up → tests → docs) and shipping the bundle
without them would have produced lying-field footguns where operator-
visible config options stored values without affecting behavior.

WHAT LANDS:

Phase A — Clock-skew tolerance (master prompt §15 hazard closure)
  internal/scep/intune/challenge.go: ValidateChallenge migrated from
  positional args to ValidateOptions{} struct; new ClockSkewTolerance
  field with default 0 (strict). 24 call sites updated mechanically.
  Asymmetric application: now+tolerance >= iat AND now-tolerance < exp.
  internal/config/config.go: SCEPIntuneProfileConfig.ClockSkewTolerance
  default 60s + Validate() refusal when >= ChallengeValidity.
  cmd/server/main.go: SetIntuneIntegration signature extended;
  per-profile env-var loader honors CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CLOCK_SKEW_TOLERANCE.
  internal/service/scep.go: intuneClockSkew field + IntuneStatsSnapshot
  surfaces clock_skew_tolerance_ns. web/src/api/types.ts mirrors.
  4 new tests in challenge_test.go covering accept-within-tolerance,
  reject-beyond-tolerance, accept-expired-within-tolerance,
  negative-treated-as-zero defensive normalization.
  docs/scep-intune.md updated with the new env var + time-bounds rule.

Phase B — unknown-version-rejected golden test
  internal/scep/intune/golden_helper_test.go: goldenUnknownVersionPayload
  helper + signGoldenChallengeAny generic signer.
  challenge_golden_test.go: TestGoldenChallenge_UnknownVersionRejected
  uses an in-process ECDSA fixture (the on-disk PEM was generated with
  a Go-stdlib version that produces different ecdsa.GenerateKey bytes
  from the current call). TestRegenerateGoldenFixtures emits the new
  unknown_version fixture file too.

Phase C — Two named Intune e2e tests
  internal/api/handler/scep_intune_e2e_test.go:
    TestSCEPIntuneEnrollment_RateLimited_E2E (cap=2 + 3 attempts; 3rd
    returns FAILURE+badRequest with rate_limited counter ticked)
    TestSCEPIntuneEnrollment_TrustAnchorSIGHUPReload_E2E (rotate
    on-disk PEM + holder.Reload(); old-key challenge fails with
    badMessageCheck; signature_invalid counter ticked)
  intuneE2EFixture struct extended with trustHolder + trustPath fields
  so tests can rotate.

Phase D — Four new ChromeOS hermetic tests (10 total now)
  internal/api/handler/scep_chromeos_test.go:
    _RAKeyMismatch — PKIMessage encrypted to wrong RA cert; handler
      rejects without reaching service.
    _3DESBackwardCompat — RFC 8894 §3.5.2 legacy fallback verified.
    _RSACSR + _ECDSACSR — explicit matrix-pair pinning.
  buildTestECDSACSR helper for ECDSA P-256 CSR construction;
  tripleDESCBCEncrypt mirrors aesCBCEncrypt for 3DES-CBC;
  assertChromeOSPositiveCertRep shared assertion.

Phase E — Per-profile counter isolation test
  internal/api/handler/scep_profile_counter_isolation_test.go:
    TestSCEPHandler_PerProfileIntuneCountersIsolated wires two
    SCEPService instances + drives distinct PKIMessages + asserts
    counter isolation. Guards against a future cmd/server/main.go
    refactor that shares a *intuneCounterTab across profiles.
  buildPerProfileIntuneFixture parameterized helper.

Phase F — Server-boot regression tests
  cmd/server/preflight_scep_intune_test.go: 3 named tests covering
  disabled-backward-compat, broken-config-with-PathID, expired-cert
  refusal. preflightSCEPIntuneTrustAnchor signature extended with
  pathID arg so error messages carry PathID= for operator log-grep.

Phase G — docs/connectors.md
  Four new subsections under §EST/SCEP Integration: multi-profile
  dispatch + mTLS sibling route + Intune Connector dispatcher + SCEP
  probe in network scanner. Each has a one-paragraph operator
  explanation + an env-var or endpoint table.

Phase H — Coverage uplift
  internal/service/scep_probe_persist_test.go: 5 unit tests on
  persistProbeResult (nil-safe + nil-repo-safe + repo-error swallow +
  nil-logger guard) + ListRecentSCEPProbes (empty-slice-not-nil + repo
  pass-through) + describeCertAlgorithm (RSA/ECDSA/QF1008-nil-curve
  defensive branch/Ed25519/DSA/empty). CI gates (service ≥70, handler
  ≥75) PASS at 70.9% / 79.3%.

Phase I — deploy/test integration variant
  deploy/test/scep_intune_e2e_test.go (//go:build integration):
    TestSCEPIntuneEnrollment_Integration + _RateLimited_Integration
    against the live docker-compose certctl container. Skip-when-
    stack-missing semantics so sandbox + CI both work.
  deploy/docker-compose.test.yml: new e2eintune SCEP profile env
  vars + bind-mount of deploy/test/fixtures/.
  deploy/test/fixtures/README.md: documents the deterministic trust
  anchor regeneration recipe.

Shankar 1af082c410 feat(scep): SCEP probe in network scanner for fleet-readiness assessment
Phase 11.5 of the SCEP RFC 8894 + Intune master bundle. Adds an
operator-facing SCEP probe that issues GetCACaps + GetCACert against
an arbitrary SCEP server URL and returns a structured posture snapshot
(reachable + advertised caps + RFC 8894 / AES / POST / Renewal /
SHA-256 / SHA-512 support flags + CA cert subject + issuer + NotBefore
+ NotAfter + days-to-expiry + algorithm + chain length).

Two operator use cases per the master prompt:

  1. Pre-migration assessment — probe an existing EJBCA / NDES SCEP
     server before switching to certctl to see what capabilities it
     advertises and what the CA cert looks like.
  2. Compliance posture audits — periodic ad-hoc probes against the
     operator's own SCEP servers to flag drift.

Capability-only — does NOT POST a CSR per the spec (would consume slot
allocations on the target server + create audit noise). Standalone CLI
binary explicitly out of scope (per the master prompt §11.5.6 and the
operator's confirmation): the probe code lands inside certctl; a
future thin Cobra wrapper is a separate decision.

Backend (six new + one extended file):

  * internal/domain/network_scan.go — new SCEPProbeResult struct with
    every probe field documented for the GUI's display layer.

  * migrations/000021_scep_probe_results.up.sql + .down.sql — new
    scep_probe_results table with TEXT id, target_url, all probe
    flags, CA cert metadata, probed_at, probe_duration_ms, error.
    Two indexes: idx_scep_probe_results_probed_at (DESC) for the
    'recent probes' GUI query, idx_scep_probe_results_target_url
    (target_url, probed_at DESC) for the future per-URL history view.

  * internal/repository/interfaces.go — new SCEPProbeResultRepository
    interface (Insert + ListRecent).

  * internal/repository/postgres/scep_probe_results.go — Postgres
    implementation. ListRecent clamps limit to [1, 200]; on read
    re-derives ca_cert_days_to_expiry against the query-time wall
    clock so 'X days remaining' stays fresh.

  * internal/service/scep_probe.go — ProbeSCEP(ctx, url) on
    NetworkScanService. Validation order:
      1. Up-front URL validation via validation.ValidateSafeURL
         (defaults to validation.ValidateSafeURL but injectable for
         tests via the new scepValidateURL field on the service).
      2. Dial-time SSRF re-check via SafeHTTPDialContext on the
         http.Transport (defends against DNS rebinding).
      3. GET ?operation=GetCACaps + GET ?operation=GetCACert.
         GetCACert handles three response shapes: PKCS#7 SignedData
         certs-only envelope (multi-cert), raw DER (single-cert),
         and PEM-wrapped DER (non-conforming servers).
    Times out at 30s; uses a 1MB body cap for DoS defense; wraps
    the result + persists via the repo (nil-safe) before returning.
    describeCertAlgorithm helper returns 'RSA-N' / 'ECDSA-curve' /
    'Ed25519' / 'DSA' for the GUI's algorithm column.

  * internal/service/network_scan.go — added scepProbeRepo +
    scepHTTPClient + scepValidateURL + scepIDFn + nowFn fields;
    SetSCEPProbeRepo wires the repo at startup.

  * internal/api/handler/network_scan.go — extended NetworkScanService
    interface with ProbeSCEP + ListRecentSCEPProbes; added two new
    HTTP handlers:
      POST /api/v1/network-scan/scep-probe   (body {url})
      GET  /api/v1/network-scan/scep-probes  (recent history)
    Synchronous probe; HTTP 200 with the result body for both success
    and reachable-but-failed cases (so the GUI can render the failure
    tone with the operator-actionable error message).

  * internal/api/router/router.go — registered the two routes inline
    after the existing network-scan target endpoints.

  * api/openapi.yaml — documented both endpoints (operationId
    probeSCEP + listSCEPProbes) with full schema + response codes.

  * cmd/server/main.go — wires the new SCEPProbeResultRepository
    onto the network scan service via SetSCEPProbeRepo right after
    the existing NewNetworkScanService construction.

Backend tests (6 new — exit-criteria-named per the master prompt):

  * TestProbeSCEP_AdvertisesAllCaps — happy path, full RFC 8894
    capability set, ECDSA P-256 CA cert, 365-day expiry.
  * TestProbeSCEP_MissingSCEPStandard — pre-RFC-8894 server (only
    POSTPKIOperation + SHA-1 + DES3); SupportsRFC8894 = false.
  * TestProbeSCEP_GetCACertExpired — CA cert NotAfter 30d in the
    past; CACertExpired = true.
  * TestProbeSCEP_Unreachable — connect to TCP port 1; probe
    returns Reachable=false + non-empty Error.
  * TestProbeSCEP_RejectsReservedIP — http://169.254.169.254/scep
    (EC2 metadata literal) rejected by the up-front
    validation.ValidateSafeURL gate; result captures the error
    without ever issuing the HTTP call.
  * TestProbeSCEP_PEMWrappedCert — server returns PEM instead of
    raw DER for GetCACert; the fallback parse path handles it.

Frontend (one extended file + types/client):

  * web/src/api/types.ts — SCEPProbeResult + SCEPProbesResponse.
  * web/src/api/client.ts — probeSCEPServer + listSCEPProbes
    helpers.
  * web/src/pages/NetworkScanPage.tsx — new SCEPProbeSection
    component + ProbeResultPanel (with capability badges + CA cert
    details panel + raw caps line) + SCEPProbeHistoryTable. Form
    rejects empty URL with inline error before calling the API.
    Reload mutation goes through useTrackedMutation with explicit
    invalidates: [['scep-probes']] (M-009 contract).

Frontend tests (5 new + 0 regressions):

  * Scep probe section header + form renders.
  * Empty URL is rejected with inline error and never calls the
    probe endpoint.
  * Successful probe renders capability badges + CA cert subject
    + days-remaining inline panel.
  * Probe-level errors are surfaced in the inline panel (no result
    panel rendered).
  * Recent-probes history table renders one row per probe.
  * (Existing 2 NetworkScanPage XSS-hardening tests stub the new
    listSCEPProbes endpoint to an empty list so they still pass.)

Verification:
  * gofmt clean on touched files
  * go vet ./... clean
  * staticcheck on service+handler+router+repository+cmd-server clean
  * go test -short across service+handler+router+repository+cmd-server
    + integration: all green (existing + 6 new probe tests pass)
  * Frontend tsc --noEmit clean
  * Vitest: 7/7 NetworkScanPage tests pass (2 existing XSS + 5 new
    probe section)
  * G-3 docs-drift CI guard reproduced locally clean (no new env vars)
  * M-009 hard-zero useMutation guard clean (probe mutation goes
    through useTrackedMutation)
  * openapi-parity guard satisfied (both new routes documented)
  * The mockNetworkScanService in handler + integration packages
    extended with stub Probe methods; targeted coverage stays in
    scep_probe_test.go.

Out of scope (per master prompt §11.5.6 + operator confirmation):
  * Standalone certctl-scan CLI binary — separate decision, ~1d of
    follow-up work when/if shipped.

Shankar 5b67ff3944 refactor(scep-gui): rebrand SCEP admin surface to per-profile tabbed interface (Profiles + Intune + Recent Activity)
Phase 9 follow-up to the SCEP RFC 8894 + Intune master bundle. The
Phase 9.4 GUI shipped 'SCEP Intune Monitoring' at /scep/intune, which
made the per-profile observability surface look Intune-only — operators
running EJBCA + Jamf would never click that nav link expecting per-
profile RA cert + mTLS observability. The page is per-profile keyed
under the hood; this commit rebrands + restructures so the surface
matches what operators actually need.

Spec: cowork/scep-gui-restructure-prompt.md.

User-visible change:

  - Nav link renamed: 'SCEP Intune' → 'SCEP Admin'.
  - Route: /scep is the new canonical path; /scep/intune kept as a
    backward-compat alias that lands directly on the Intune tab.
  - Page header: 'SCEP Administration'.
  - Three tabs:
      * Profiles (default) — per-profile lean cards with RA cert
        expiry countdown, mTLS sibling-route status badge, Intune
        enabled/disabled badge, challenge-password-set indicator.
        'View Intune details →' link on Intune-enabled cards
        deep-links into the Intune tab.
      * Intune Monitoring — the existing Phase 9.4 deep-dive
        (per-status counters, trust anchor expiry, recent failures
        table, reload-trust button + confirmation modal).
      * Recent Activity — full SCEP audit log filter merging all
        four action codes (scep_pkcsreq + scep_renewalreq +
        scep_pkcsreq_intune + scep_renewalreq_intune); chip filters
        for All / Initial / Renewal / Intune / Static.

Backend:

  * internal/service/scep.go — new SCEPProfileStatsSnapshot type +
    IntuneSection sub-block + ProfileStats(now) accessor. Adds
    raCertSubject/raCertNotBefore/raCertNotAfter + mtlsEnabled +
    mtlsTrustBundlePath fields with SetRACert + SetMTLSConfig setters.
    Existing IntuneStatsSnapshot + IntuneStats(now) preserved
    UNCHANGED for /admin/scep/intune/stats backward compat (the
    JSON shape stays byte-stable for external consumers — the
    aliasing approach the prompt initially suggested doesn't work
    because the new shape nests Intune while the old one is flat).
    ChallengePasswordSet is derived from challengePassword != ''
    (the secret value itself is never surfaced).

  * internal/api/handler/admin_scep_intune.go — new Profiles handler
    method on AdminSCEPIntuneHandler with the same M-008 admin gate.
    AdminSCEPIntuneServiceImpl extended (in place; same
    map[string]*service.SCEPService) to satisfy the new
    AdminSCEPProfileService interface. Single handler file gets the
    third method so the M-008 pin entry count stays steady (no new
    file, no new triplet of admin-gate test files — just three new
    Profiles tests inside the existing test file).

  * internal/api/router/router.go — one new route
    'GET /api/v1/admin/scep/profiles' registered to
    reg.AdminSCEPIntune.Profiles. HandlerRegistry unchanged.

  * api/openapi.yaml — new operation 'listSCEPProfiles' documenting
    the request body / response shape / error mapping. Existing
    Intune entries unchanged.

  * cmd/server/main.go — per-profile loop now calls
    scepService.SetMTLSConfig(profile.MTLSEnabled,
    profile.MTLSClientCATrustBundlePath) right after SetPathID, and
    scepService.SetRACert(raCert) right after loadSCEPRAPair returns
    the leaf cert. Both setters are nil-safe.

  * internal/api/handler/m008_admin_gate_test.go — extended the
    existing admin_scep_intune.go entry's justification to mention
    the third endpoint. No new map entry needed (file already
    listed).

Backend tests (8 new):

  * TestAdminSCEPProfiles_NonAdmin_Returns403
  * TestAdminSCEPProfiles_AdminExplicitFalse_Returns403
  * TestAdminSCEPProfiles_AdminPermitted_ForwardsActor — also pins
    that Intune-enabled profiles emit an 'intune' sub-block while
    Intune-disabled profiles OMIT it.
  * TestAdminSCEPProfiles_RejectsNonGetMethod
  * TestAdminSCEPProfiles_PropagatesServiceError
  * TestAdminSCEPProfilesServiceImpl_NilMapReturnsEmpty
  * (existing 16 Phase 9 admin tests still pass — backward-compat
    preserved)

Frontend:

  * web/src/api/types.ts — new SCEPProfileStatsSnapshot +
    IntuneSection + SCEPProfilesResponse types. Existing
    IntuneStatsSnapshot et al unchanged.
  * web/src/api/client.ts — new getAdminSCEPProfiles helper.
  * web/src/pages/SCEPAdminPage.tsx — full rewrite as the tabbed
    surface. Reuses the existing ConfirmReloadModal and Intune
    deep-dive card components verbatim; adds ProfileSummaryCard
    (lean card for the Profiles tab) and ActivityTab. URL state
    sync via useSearchParams so deep links survive reloads + browser
    back/forward. The legacy /scep/intune route alias defaults the
    activeTab to 'intune' on mount.
  * web/src/main.tsx — new <Route path='scep' /> + preserved
    <Route path='scep/intune' /> alias. Both render SCEPAdminPage.
  * web/src/components/Layout.tsx — nav link rebranded:
    label 'SCEP Intune' → 'SCEP Admin', to '/scep/intune' → '/scep'.

Frontend tests (20 — full rebuild):

  * Admin gate (non-admin sees gated banner + zero admin API calls)
  * Profiles tab default + Intune tab tabswitch + ?tab=intune deep
    link + legacy /scep/intune alias all land on Intune
  * Profiles tab status badges (Intune + mTLS + challenge-set)
    reflect each profile's flags
  * RA cert expiry tone bands (good ≥30d / warn 7-30d / bad <7d /
    EXPIRED) verified across three fixture profiles
  * 'View Intune details →' only renders for Intune-enabled
    profiles AND switches tabs on click
  * Empty-state banner when no profiles configured
  * Intune tab counters render with the existing Phase 9 deep-dive
    shape; reload modal Open/Confirm/Cancel/Error paths all pinned
  * Recent Activity tab merges all four SCEP audit actions across
    four parallel useQuery calls; filter chips
    (all/initial/renewal/intune/static) narrow correctly
  * Error path surfaces ErrorState on the active tab

Docs:

  * docs/scep-intune.md — Operational monitoring section heading
    expanded to '(SCEP Administration → Intune Monitoring tab)'.
    Page-surface description rewritten for the tabbed shape;
    admin-endpoints list extended with the new /admin/scep/profiles
    entry.
  * docs/architecture.md — Microsoft Intune Connector trust anchor
    subsection updated to reference the Intune Monitoring tab inside
    the SCEP Administration page + lists all three admin endpoints.
  * docs/legacy-est-scep.md — forward-ref expanded with a parallel
    sentence for the per-profile observability surface (independent
    of Intune).
  * README.md — Enrollment Protocols bullet for Intune updated to
    'admin GUI SCEP Administration page at /scep' with the three
    tabs called out.

Verification:
  * gofmt clean on touched files
  * go vet ./... clean
  * staticcheck on intune+service+handler+router+cmd-server clean
  * go test -short across intune+service+handler+router+cmd-server:
    all green (existing Phase 9 tests + new Profiles tests)
  * Frontend tsc --noEmit clean
  * Vitest: 20/20 SCEPAdminPage tests + 3/3 sibling AuditPage tests
    pass
  * G-3 docs-drift CI guard reproduced locally: clean (no new env
    vars; existing CERTCTL_SCEP_ allowlist prefix covers everything)
  * M-009 hard-zero useMutation guard reproduced locally: clean
    (the existing reload mutation already used useTrackedMutation
    from the Phase 9 follow-up commit 96e81b6)
  * openapi-parity test green (new GET /api/v1/admin/scep/profiles
    operation documented)
  * M-008 admin-gate scanner green (existing admin_scep_intune.go
    entry covers all three handler methods; the test scanner
    enforces the triplet by file, not by endpoint, and the new
    Profiles triplet was added to the existing test file)

Backward compat preserved:
  * /api/v1/admin/scep/intune/stats unchanged — same JSON shape,
    same error codes, same M-008 gate
  * /api/v1/admin/scep/intune/reload-trust unchanged
  * /scep/intune route still works (alias to /scep with activeTab=intune)
  * IntuneStatsSnapshot Go type unchanged
  * IntuneStats(now) accessor unchanged

Shankar c2a8533ffe feat(scep-intune): golden-file tests + e2e harness against fixture trust anchor
Phase 10 of the SCEP RFC 8894 + Intune master bundle. Adds reproducible
testdata fixtures + a hermetic end-to-end test that exercises the full
handler → service → dispatcher → CertRep wire path.

Phase 10.1 — Golden-file tests (internal/scep/intune/):

  * testdata/intune_trust_anchor.pem — deterministic ECDSA P-256 cert
    seeded from a constant byte string (sha256-derived PRNG); regenerates
    byte-identical PEM bytes across runs.
  * testdata/intune_challenge_golden_success.txt — valid challenge,
    iat/exp window covers goldenChallengeNow.
  * testdata/intune_challenge_golden_expired.txt — same trust anchor +
    payload shape but iat/exp shifted into the past.
  * testdata/intune_challenge_golden_tampered_sig.txt — payload bytes
    intact, last sig byte flipped.

  challenge_golden_test.go reads each fixture and asserts:
    - Success → ValidateChallenge returns a populated claim
      (DeviceName / Subject / SANDNS pinned to the documented values).
    - Expired → errors.Is(err, ErrChallengeExpired).
    - Tampered → errors.Is(err, ErrChallengeSignature).
    - Plus two defensive permutations: WrongAudienceReuse pins the
      audience-check ordering after a successful sig verify;
      RotatedTrustAnchorRejects pins the holder-rotation failure mode
      using a freshly-generated unrelated trust cert.

  golden_helper_test.go contains the deterministic-PRNG, ES256 signer,
  fixture-load helpers, and the regeneration target. Operators flip
  fixtures via:
    go test -run='^TestRegenerateGoldenFixtures$'             ./internal/scep/intune/... -args -update-golden

  Why ECDSA + a deterministic seed: a hand-pasted base64 blob would
  break on every Go stdlib bump (json.Marshal field ordering, ASN.1
  encoding edge cases). Generating from a pinned seed gives
  reproducible PEM bytes; only the ECDSA signature suffix varies
  across regenerations (Go's stdlib doesn't expose RFC 6979
  deterministic-k cleanly), and ValidateChallenge re-verifies the
  signature on every read so it doesn't matter.

  intune package coverage: 95.2% (was 94.8%).

Phase 10.2 — Hermetic end-to-end test (internal/api/handler/scep_intune_e2e_test.go):

  Departs from the spec's deploy/test/ location because the handler
  package already has the chromeOS-shape PKIMessage builders (buildTestCSR
  / buildEnvelopedDataForTest / buildSignedDataForTest / aesCBCEncrypt /
  postPKIOperation). Putting the e2e test in the handler package lets it
  reuse those helpers AND run in the default 'go test ./...' sweep —
  every CI run exercises the full Intune dispatcher chain. The
  deploy/test/ location is reserved for a future docker-compose-driven
  variant that would mount a fixture trust anchor into the running
  container; this hermetic version proves the wire works without that
  dependency.

  intuneE2EFixture stands up:
    - A real Intune Connector signing keypair (ECDSA P-256) + cert
      written to a temp PEM file the TrustAnchorHolder loads at startup.
    - A real RA pair the SCEPHandler decrypts EnvelopedData with.
    - A fixture issuer connector (intuneE2EIssuerConnector) that
      records every IssueCertificate call + returns a deterministic
      child cert chained to a fixture CA. Implements the full
      IssuerConnector interface (IssueCertificate / RenewCertificate /
      RevokeCertificate / GenerateCRL / SignOCSPResponse / GetRenewalInfo)
      with the non-issuance methods stubbed.
    - A capturing AuditRepository that records every Create call so
      the test can assert action='scep_pkcsreq_intune' was emitted.
    - A real SCEPService with SetIntuneIntegration wired to a real
      ReplayCache + PerDeviceRateLimiter.

  Three test scenarios:

    1. TestSCEPIntuneEnrollment_E2E — the documented happy path. Forge
       a valid Intune-shaped challenge (ES256 signed, length > 200, two
       dots — satisfies looksIntuneShaped), build a CSR with CN matching
       the claim's device_name, POST through HandleSCEP, decode the
       CertRep, assert pkiStatus=SUCCESS + issuer.issued has one entry
       + audit log carries 'scep_pkcsreq_intune' + IntuneStats.counters[
       'success']==1.

    2. TestSCEPIntuneEnrollment_ClaimMismatchRejected_E2E — same setup
       but CSR CN is 'attacker-host.example.com'. Dispatcher must
       reject with CertRep FAILURE+BadRequest (mapIntuneErrorToFailInfo:
       ErrClaimCNMismatch → BadRequest), no issuance, IntuneStats
       counters['claim_mismatch']==1.

    3. TestSCEPIntuneEnrollment_TamperedSignature_E2E — flip a byte in
       the JWT signature segment of the Intune challenge before
       wrapping it in the PKIMessage. Dispatcher rejects with
       FAILURE+BadMessageCheck (signature errors → BadMessageCheck per
       the same mapping table).

  Important sanity learning during construction: the buildTestCSR
  helper from scep_chromeos_test.go does NOT populate DNSNames on the
  CSR. The success claim therefore omits san_dns to avoid tripping
  ErrClaimSANDNSMismatch (claim says ['x'], CSR has nothing). The
  claim_mismatch sibling test exercises the SAN-dimension via the
  CN mismatch path; coverage of explicit SANDNS mismatches stays in
  the unit tests in claim_test.go where the helper builds CSRs with
  full SANs.

Verification:
  * gofmt clean on touched files
  * go vet ./internal/scep/intune/... ./internal/api/handler/...: clean
  * staticcheck: clean
  * go test -count=1 -cover ./internal/scep/intune/...: 95.2%
  * 5 golden tests + 3 e2e tests all pass
  * No new env vars (G-3 docs guard not triggered)
  * No new HTTP routes (openapi-parity guard not triggered)
  * Sibling test packages (service + router) still green

Shankar 82276bd29e feat(scep-intune): GUI monitoring tab + admin endpoints
Phase 9 of the SCEP RFC 8894 + Intune master bundle. Lands the operator-
facing Intune Monitoring tab plus the two admin-gated endpoints it reads
from. Per the constitutional 'complete path' rule: counters tick on
every typed dispatcher branch, the GUI poll is live (30s for stats,
60s for the audit log filter), and the SIGHUP-equivalent reload action
is one click + a confirmation modal — no follow-up plumbing required.

Backend (Phase 9.1 + 9.2 + 9.3):

  * internal/service/scep.go gains:
    - intuneCounterTab — atomic per-status counters keyed by the same
      labels intuneFailReason() emits (success / signature_invalid /
      expired / not_yet_valid / wrong_audience / replay / rate_limited /
      claim_mismatch / compliance_failed / malformed / unknown_version).
      Lock-free on the dispatcher hot path; snapshot() returns a
      zero-allocation map for the admin endpoint.
    - dispatchIntuneChallenge wires intuneCounters.inc(...) on every
      typed return path INCLUDING the success leg (credited before
      processEnrollment so a downstream issuer-connector failure
      doesn't double-count).
    - SetPathID + PathID accessors (so admin rows surface the SCEP
      profile path ID per row).
    - IntuneStatsSnapshot + IntuneTrustAnchorInfo public types, plus
      IntuneStats(now) accessor that walks the trust holder pool and
      packages a per-profile snapshot. ReloadIntuneTrust() is the
      typed wrapper around TrustAnchorHolder.Reload that returns
      ErrSCEPProfileIntuneDisabled when called on a profile where
      Intune isn't enabled (admin endpoint maps that to HTTP 409).

  * internal/api/handler/admin_scep_intune.go:
    - AdminSCEPIntuneService narrow interface (Stats + ReloadTrust)
      so the handler depends on a small surface; AdminSCEPIntuneServiceImpl
      is the production walker over the per-profile SCEPService map.
    - AdminSCEPIntuneHandler.Stats handles GET /api/v1/admin/scep/intune/stats
      with the M-008 admin gate (non-admin → 403 + service never
      invoked); returns {profiles, profile_count, generated_at}.
    - AdminSCEPIntuneHandler.ReloadTrust handles POST
      /api/v1/admin/scep/intune/reload-trust. Body is {path_id: '<id>'};
      empty body targets the legacy /scep root profile. Returns 200 on
      success / 404 on unknown PathID / 409 when the profile is Intune-
      disabled / 500 on a parse error from intune.LoadTrustAnchor (the
      holder retains its previous pool — fail-safe). 400 on malformed
      JSON.
    - ErrAdminSCEPProfileNotFound typed error so the handler can
      distinguish 'wrong profile' from 'broken file'.

  * internal/api/router/router.go: HandlerRegistry gains
    AdminSCEPIntune; both routes registered as bearer-auth-required
    (the admin-gate is at the handler layer per the M-008 pattern).

  * cmd/server/main.go: declares scepServices map[string]*service.SCEPService
    BEFORE HandlerRegistry construction so the same map can be referenced
    from both the admin handler (constructed early) and the SCEP startup
    loop (which populates it later by reference). The per-profile loop
    now calls scepService.SetPathID(profile.PathID) and stores the service
    pointer into the shared map. AdminSCEPIntune handler is constructed
    at the same time as AdminCRLCache.

  * internal/api/handler/m008_admin_gate_test.go: AdminGatedHandlers
    map gains 'admin_scep_intune.go' with a one-line justification —
    the regression scanner enforces the per-handler test triplet
    (TestAdminSCEPIntune_NonAdmin_Returns403 + _AdminExplicitFalse_Returns403
    + _AdminPermitted_ForwardsActor) plus their POST siblings for
    ReloadTrust.

  * api/openapi.yaml: documents both endpoints with request body /
    response shape / error mapping; openapi-parity-test now matches
    the registered routes.

Frontend (Phase 9.4):

  * web/src/pages/SCEPAdminPage.tsx — single-page Intune Monitoring
    surface:
    - Per-profile cards (one card per SCEP profile). Enabled profiles
      get the full counter grid + trust-anchor-expiry badge tone
      (good ≥30d / warn 7-30d / bad <7d / EXPIRED). Disabled profiles
      get an off-state pill with the env-var hint to opt in.
    - Counters polled every 30s via TanStack Query against
      GET /admin/scep/intune/stats.
    - Recent failures table (last 50) populated from the audit log
      filtered to action=scep_pkcsreq_intune AND scep_renewalreq_intune;
      merged + sorted by timestamp descending. Polled every 60s.
    - Reload trust anchor button per profile + confirmation modal that
      explains the SIGHUP equivalence and the fail-safe behavior.
      onConfirm runs a TanStack mutation, refetches the stats query
      on success, surfaces the underlying error (eg 'trust anchor
      cert expired') in the modal on failure (modal stays open so
      operator can retry).
    - Admin gate: when authRequired && !admin the page renders an
      'Admin access required' banner and the underlying admin API
      requests are never issued (React Query enabled flag gated on
      auth.admin) — server-side enforcement is M-008.

  * web/src/api/types.ts: IntuneStatsSnapshot + IntuneTrustAnchorInfo +
    IntuneStatsResponse + IntuneReloadTrustResponse.

  * web/src/api/client.ts: getAdminSCEPIntuneStats +
    reloadAdminSCEPIntuneTrust(pathID).

  * web/src/main.tsx: new route /scep/intune. The route is unconditional;
    the gating is at the page level so deep-links land cleanly.

  * web/src/components/Layout.tsx: 'SCEP Intune' nav link between
    Observability and Audit Trail with the appropriate sidebar icon.

Tests (Phase 9.5):

  * internal/api/handler/admin_scep_intune_test.go (16 tests):
    - M-008 admin-gate triplet for both Stats (GET) and ReloadTrust
      (POST): NonAdmin / AdminExplicitFalse / AdminPermitted.
    - Method-gate tests (Stats rejects POST, ReloadTrust rejects GET).
    - Stats propagates service errors as 500.
    - ReloadTrust maps ErrAdminSCEPProfileNotFound→404,
      ErrSCEPProfileIntuneDisabled→409, generic err→500.
    - Empty body targets legacy root PathID.
    - Malformed JSON→400.
    - AdminSCEPIntuneServiceImpl handles nil map + unknown PathID.

  * web/src/pages/SCEPAdminPage.test.tsx (13 tests):
    - Admin gate (non-admin sees gated banner + zero admin API calls;
      admin sees the page; no-auth dev mode also passes).
    - Profile rendering (counters with correct labels, expiry badge
      tone for ≥30d / EXPIRED states, off-state pill for disabled
      profiles, empty-state banner when no profiles configured).
    - Reload modal (opens on click, calls mutation on Confirm,
      keeps modal open + shows error on failure, Cancel skips
      mutation).
    - Error path renders ErrorState with retry.
    - Audit log filter merges PKCSReq + RenewalReq events and sorts
      descending.

Verification:

certctl-copilot e7a3075a75 feat(scep): mTLS sibling route /scep-mtls/<pathID> (opt-in)
SCEP RFC 8894 + Intune master bundle — Phase 6.5 of 14 (opt-in,
enterprise-procurement-checkbox).

Closes the procurement-team objection that 'shared password
authentication' is a checkbox-fail regardless of how strong the
password is. The clean answer: a sibling route that adds client-cert
auth at the handler layer AND keeps the challenge password (defense in
depth, not replacement). Devices present a bootstrap cert from a
trusted CA (e.g. a manufacturing-time cert), then SCEP-enroll for
their long-lived cert. Same model Apple's MDM and Cisco's BRSKI use.

internal/config/config.go
  * SCEPProfileConfig gains MTLSEnabled bool + MTLSClientCATrustBundlePath
    string. Indexed env-var loader reads
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED +
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_CLIENT_CA_TRUST_BUNDLE_PATH.
  * Validate() refuses MTLSEnabled=true with empty bundle path —
    structural defense in depth ahead of the file-content preflight.

cmd/server/main.go
  * preflightSCEPMTLSTrustBundle: file existence + PEM parse + ≥1
    CERTIFICATE block + non-expired check. Returns the parsed
    *x509.CertPool ready to inject into the per-profile SCEPHandler.
    Failures os.Exit(1) with the offending PathID in the structured log.
  * SCEP startup loop walks each profile; when MTLSEnabled, runs
    preflight, builds the per-profile pool, contributes the bundle's
    certs to the union pool that backs the TLS-layer
    VerifyClientCertIfGiven, clones the SCEPHandler with
    SetMTLSTrustPool, and registers the parallel sibling route via
    apiRouter.RegisterSCEPMTLSHandlers.
  * Union pool published to outer scope as scepMTLSUnionPoolForTLS;
    passed to buildServerTLSConfigWithMTLS so the listener serves both
    /scep[/<pathID>] (no client cert) and /scep-mtls/<pathID>
    (cert required at handler layer) on the same socket.
  * Final-handler dispatch gains /scep-mtls + /scep-mtls/* prefix
    routing through the no-auth chain (auth boundary is the client
    cert + challenge password, NOT a Bearer token).

cmd/server/tls.go
  * New buildServerTLSConfigWithMTLS that wraps buildServerTLSConfig
    + sets ClientCAs + ClientAuth=VerifyClientCertIfGiven when a
    non-nil pool is passed. nil pool = identical TLS shape to the
    pre-Phase-6.5 builder (no behavior change for deploys without
    mTLS profiles).
  * Critical: VerifyClientCertIfGiven (NOT RequireAndVerifyClientCert)
    so a client that doesn't present a cert can still hit the standard
    /scep route. The per-profile gate at the handler layer enforces
    'cert required' on /scep-mtls/<pathID>.

internal/api/handler/scep.go
  * SCEPHandler gains mtlsTrustPool *x509.CertPool field +
    SetMTLSTrustPool method. Per-profile pool injected by
    cmd/server/main.go after preflight.
  * HandleSCEPMTLS wrapper: gates on r.TLS.PeerCertificates non-empty
    + per-profile cert.Verify against THIS profile's pool. Returns
    HTTP 401 for missing/untrusted cert (mTLS failure is auth, not
    authorization). Returns HTTP 500 if mtlsTrustPool is nil (deploy
    bug — the route shouldn't have been registered). On success
    delegates to HandleSCEP — defense in depth: mTLS is additive,
    NOT replacement; the standard SCEP code path including the
    challenge-password gate still executes.
  * Per-profile re-verification via cert.Verify(...) is critical:
    the TLS layer verified against the UNION pool, so a cert that
    chains to profile A's bundle would pass TLS even when targeting
    profile B. The handler-layer gate prevents cross-profile
    bleed-through.

internal/api/router/router.go
  * AuthExemptDispatchPrefixes gains '/scep-mtls' (auth boundary is
    client cert + challenge password, NOT Bearer token).
  * RegisterSCEPMTLSHandlers parallel to RegisterSCEPHandlers:
    empty PathID maps to /scep-mtls root; non-empty maps to
    /scep-mtls/<pathID>. Each handler in the map MUST have had
    SetMTLSTrustPool called.

internal/api/router/openapi_parity_test.go
  * SpecParityExceptions allowlists 'GET /scep-mtls' + 'POST
    /scep-mtls' since the wire format is identical to /scep —
    documenting both routes separately would duplicate every
    operation row with no information gain. Documented alternative
    in docs/legacy-est-scep.md.

internal/api/handler/scep_mtls_test.go (new, ~210 LoC)
  * 6 tests + 2 helpers covering the auth contract:
    1. RejectsMissingClientCert — request with r.TLS=nil → 401
    2. RejectsUntrustedClientCert — cert chains to a different
       CA → 401 (per-profile re-verification works)
    3. AcceptsTrustedClientCert — cert chains to THIS profile's
       pool → 200 (delegates to HandleSCEP)
    4. StillRoutesThroughHandleSCEP — pin Content-Type + body
       come from HandleSCEP delegate (defense in depth pin)
    5. NoTrustPool_Returns500 — handler with SetMTLSTrustPool
       never called → 500 (deploy-bug surface)
    6. StandardRoute_StillNoMTLS — pin /scep keeps working
       without a client cert even when mTLS pool is set
  * genSelfSignedECDSACA + signECDSAClientCert helpers materialise
    real cert chains (trusted-bootstrap-ca + trusted-device,
    untrusted-attacker-ca + untrusted-device) so the Verify path
    exercises real x509 chain validation, not mocks.

docs/features.md
  * SCEP env-vars table extended with the two new MTLS env vars
    (CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED,
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_CLIENT_CA_TRUST_BUNDLE_PATH).
    Closes the G-3 'env var defined in Go but never documented' gate.

docs/legacy-est-scep.md
  * New 'mTLS sibling route (Phase 6.5, opt-in)' section covering
    opt-in env vars, TLS server config (union pool +
    VerifyClientCertIfGiven), handler-layer per-profile gate,
    full auth chain on /scep-mtls/<pathID>, operator migration
    workflow from challenge-password-only to challenge+mTLS.

cowork/CLAUDE.md::Active Focus
  * 'HALF 1 COMPLETE' updated from '(Phases 0-5 of 14 SHIPPED)' to
    '(Phases 0-6 + Phase 6.5 of 14 SHIPPED)'.

Verification:
  * gofmt + go vet + staticcheck clean across api/handler /
    api/router / config / cmd/server.
  * go test -short -count=1 green across api/handler (with the new
    scep_mtls_test.go) / api/router / service / config / pkcs7 /
    cmd/server / connector/issuer/local.
  * G-3 docs-drift CI guard local check: empty in both directions
    after the new MTLS env vars landed in features.md.
  * The constitutional test ('can an operator flip the bit and
    observe the behavior change end-to-end?') is YES: setting
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED=true plus the trust
    bundle path produces a working /scep-mtls/<pathID> endpoint
    that accepts trusted client certs + rejects untrusted ones,
    with no further code changes required.

Phase 6.5 of 14 in SCEP RFC 8894 + Intune master bundle.
Half 1 (Phases 0-6 + 6.5) is now FEATURE-COMPLETE for the
ChromeOS / general-MDM use case. Half 2 (Phases 7-12) adds the
Microsoft Intune dynamic-challenge layer.
2026-04-29 13:58:18 +00:00
certctl-copilot 35fcfa70f2 feat(scep): RenewalReq + GetCertInitial + ChromeOS E2E + caps + must-staple
SCEP RFC 8894 + Intune master bundle — Phase 4 + Phase 5 of 14.

Half 1 of the bundle's two halves is now COMPLETE through Phase 5:
the certctl SCEP server passes ChromeOS-shape hermetic E2E tests,
advertises the right capabilities, dispatches PKCSReq / RenewalReq /
GetCertInitial, and supports must-staple per-profile.

== Phase 4: RenewalReq + GetCertInitial wiring ============================

internal/service/scep.go
  * RenewalReqWithEnvelope (RFC 8894 §3.3.1.2) — re-enrollment with an
    existing valid cert. Same contract as PKCSReqWithEnvelope but the
    service additionally verifies that envelope.SignerCert chains to
    the issuer's CA (verifyRenewalSignerCertChain). A self-signed
    throwaway cert (initial-enrollment shape) fails this check — that's
    an indicator the client meant PKCSReq, not RenewalReq.
  * GetCertInitialWithEnvelope (RFC 8894 §3.3.3) — polling stub.
    Returns FAILURE+badCertID for all polls because deferred-issuance
    isn't supported in v1 (every PKCSReq either succeeds or fails
    synchronously). Wiring stays in place for a future enhancement.
  * Audit actions: scep_pkcsreq vs scep_renewalreq — operators can
    grep the audit log to distinguish initial enrollments from renewals.

internal/api/handler/scep.go
  * SCEPService interface gains RenewalReqWithEnvelope +
    GetCertInitialWithEnvelope.
  * pkiOperation RFC 8894 path now switches on envelope.MessageType:
    PKCSReq → PKCSReqWithEnvelope; RenewalReq → RenewalReqWithEnvelope;
    GetCertInitial → GetCertInitialWithEnvelope; unknown → CertRep+FAILURE+
    badRequest per RFC 8894 §3.3.2.2.

== Phase 5.1: GetCACaps capability advertisement =========================

internal/service/scep.go
  * Caps string extended from 'POSTPKIOperation+SHA-256+AES+SCEPStandard'
    to add 'SHA-512' (modern digest alternative now implemented in the
    Phase 2 verifier) and 'Renewal' (the messageType-17 dispatch from
    Phase 4). ChromeOS specifically looks for these capabilities to
    negotiate the strongest available cipher + digest combo.
  * scep_test.go pins the new caps so a future 'simplify caps' refactor
    doesn't quietly remove ChromeOS-required negotiation flags.

== Phase 5.2: ChromeOS-shape integration tests ===========================

internal/api/handler/scep_chromeos_test.go (new, ~570 LoC)
  * 6 hermetic E2E tests + ~12 helpers. Builds a real PKIMessage
    in-test (acting as the ChromeOS client), POSTs through the handler,
    parses the CertRep response back via the same internal/pkcs7/
    builders the handler uses.
  * TestSCEPHandler_ChromeOSPKIMessage_E2E — full RFC 8894 happy path:
    SignedData(SignerInfo(deviceCert, sig over auth-attrs)) wrapping
    EnvelopedData(KTRI(raCert), AES-CBC(CSR + challengePassword)) —
    POSTed; verifies CertRep parses + RA signature verifies.
  * TestSCEPHandler_ChromeOSPKIMessage_RenewalReq — pins messageType=17
    routes to RenewalReqWithEnvelope, NOT PKCSReqWithEnvelope.
  * TestSCEPHandler_ChromeOSPKIMessage_GetCertInitial — pins polling
    returns CertRep with pkiStatus=FAILURE + failInfo=badCertID.
  * TestSCEPHandler_ChromeOSPKIMessage_BadPOPO — corrupted signerInfo
    signature falls through to MVP path (which also rejects since the
    encrypted EnvelopedData isn't a raw CSR). No silent acceptance.
  * TestSCEPHandler_ChromeOSPKIMessage_AESVariants — table-driven
    AES-128/192/256-CBC; ChromeOS picks based on GetCACaps response.
  * TestSCEPHandler_MVPCompat_StillWorks — pins the legacy MVP raw-CSR
    path keeps working when no RA pair is configured. Backward compat
    is non-negotiable.

== Phase 5.6: must-staple per-profile policy field (RFC 7633) ============

internal/domain/profile.go
  * Added MustStaple bool to CertificateProfile. Default false; operators
    opt in once they've confirmed the TLS reverse proxy / load balancer
    staples OCSP responses (NGINX, HAProxy, Envoy support stapling but
    require explicit config).

internal/connector/issuer/interface.go
  * IssuanceRequest + RenewalRequest gained MustStaple bool (additive
    field). Connectors that don't support extension injection (Vault,
    EJBCA, ACME, etc.) silently ignore it — must-staple is a local-
    issuer-only feature in V2 since upstream connectors enforce their
    own extension policy.

internal/connector/issuer/local/local.go
  * Added oidMustStaple (1.3.6.1.5.5.7.1.24, id-pe-tlsfeature) +
    pre-encoded mustStapleExtensionValue (0x30 0x03 0x02 0x01 0x05 —
    SEQUENCE OF INTEGER {5}, the TLS Feature for status_request per
    RFC 7633 §6).
  * generateCertificate signature gained mustStaple bool; when true,
    appends pkix.Extension{Id: oidMustStaple, Critical: false, Value:
    mustStapleExtensionValue} to template.ExtraExtensions before
    x509.CreateCertificate.

internal/connector/issuer/local/must_staple_test.go (new)
  * TestGenerateCertificate_MustStapleProfile_AddsExtension —
    end-to-end: IssueCertificate with MustStaple=true → walks issued
    cert's Extensions for the OID, verifies non-critical + DER bytes
    match the constant.
  * TestGenerateCertificate_NoMustStaple_OmitsExtension — pins the
    'omit by default' contract (adding it by default would break
    customer deployments where the TLS path doesn't staple).
  * TestMustStapleConstants_PinExactRFC7633Bytes — locks the OID +
    DER bytes against RFC 7633 §6 verbatim; round-trips through
    asn1.Unmarshal as []int{5}.

Note: full service-layer plumbing (CertificateProfile.MustStaple →
IssuanceRequest.MustStaple → connector) flows through the issuer-side
field already; the per-call profile.MustStaple read at the service
layer (currently a no-op until SCEP/EST/CertificateService each plumb
through their respective IssueCertificate adapters) lands as a
follow-up. The load-bearing code path (the cert template) is correct
TODAY; flipping the service-layer flag is the missing wire.

== Phase 5.4: docs/legacy-est-scep.md ====================================

Added a new ~180-line section covering the SCEP RFC 8894 native
implementation: required env vars (CERTCTL_SCEP_RA_CERT_PATH +
_KEY_PATH), the openssl recipe for generating an RA pair, the
GetCACaps capability list, supported messageTypes, the MVP backward-
compat path, multi-profile dispatch (CERTCTL_SCEP_PROFILES + indexed
per-profile envs), ChromeOS Admin Console integration pointer, RA
cert rotation procedure, must-staple per-profile policy with the
'opt-in once your TLS path staples' caveat, operational notes
(audit actions, body-size cap, HTTPS-only), and a forward reference
to scep-intune.md (Phase 11).

== Verification ==========================================================

  * gofmt + go vet clean for the files I touched.
  * staticcheck ./internal/api/handler/... clean (the SA1019 lint on
    extractChallengePasswordFromCSR uses the line-level //lint:ignore
    directive matching the M-028 audit closure precedent).
  * go test -short -count=1 green across api/handler / api/router /
    service / pkcs7 / connector/issuer/local / domain / cmd/server.
  * G-3 docs-drift CI guard local check: empty diff in both directions.

Phase 4 + Phase 5 of 14 in SCEP RFC 8894 + Intune master bundle.
Half 1 (Phases 0-5) is now feature-complete; Phase 6 (docs + smoke +
audit deliverables) lands next; then Phase 6.5 (mTLS sibling route,
opt-in) is independently shippable; then Half 2 (Phases 7-12) adds
the Microsoft Intune dynamic-challenge layer.

certctl-copilot df0a4dd39c feat(scep): CertRep PKIMessage response builder (RFC 8894 §3.3.2)
SCEP RFC 8894 + Intune master bundle — Phase 3 of 14.

Implements the SCEP CertRep response builder + wires it into the handler's
RFC 8894 path. After this commit, certctl emits proper CertRep PKIMessage
responses (signed by the RA key, with EnvelopedData encrypting the issued
cert chain to the device's transient signing cert) for both success and
failure outcomes — RFC 8894 §3.3 mandates a PKIMessage response on every
PKIOperation request, including failure cases that carry pkiStatus=2 +
failInfo.

internal/pkcs7/certrep.go (new, ~370 LoC)
  * BuildCertRepPKIMessage: assembles the full ContentInfo → SignedData →
    {certs, signerInfo, encapContent} structure per RFC 8894 §3.3.2 +
    RFC 5652 §5+§6.
  * Success path: encrypts the issued cert chain (PKCS#7 certs-only)
    INSIDE an EnvelopedData targeting req.SignerCert (the device's
    transient cert, NOT the RA cert — response goes back to the device
    encrypted with its public key). AES-256-CBC + random 16-byte IV +
    PKCS#7 padding + RSA PKCS#1v1.5 keyTrans.
  * Failure path: encapContent is empty (no EnvelopedData); the failInfo
    auth-attr is populated.
  * Pending path: encapContent is empty; client polls via GetCertInitial.
  * Auth-attr ordering matches micromdm/scep for byte-level wire-format
    diffing (DER SET-OF normalises order anyway, but matching the
    reference implementation makes audit + manual inspection easier).
  * senderNonce is freshly generated from crypto/rand on every call.
  * RA key signs the canonical SET OF Attribute re-serialisation (RFC
    5652 §5.4 quirk every CMS implementation hits — wire form is [0]
    IMPLICIT but the signature is computed over EXPLICIT SET OF).
  * Helper functions: buildCertRepAuthAttrs, buildSignerInfoCertRep,
    signCertRep, buildEncapContentInfo, buildEnvelopedDataAES256, all
    constructed via this package's existing ASN1Wrap primitives (avoids
    asn1.Marshal nuances with nested RawValues — same pattern Phase 2
    settled on).

internal/pkcs7/signedinfo.go (1-line tweak)
  * ParseSignedData no longer refuses when SignerInfos is empty. The
    degenerate certs-only SignedData form (RFC 8894 §3.5.1 GetCACert
    response, RFC 7030 EST cacerts, AND now the encrypted certs-only
    inner content of the CertRep EnvelopedData) is structurally valid
    with zero signers. Caller decides whether the lack of signers is
    an error in their context.

internal/pkcs7/certrep_test.go (new, ~230 LoC)
  * TestBuildCertRepPKIMessage_Success_RoundTrip — full pipeline
    round-trip: build → ParseSignedData → VerifySignature → auth-attr
    extractors → ParseEnvelopedData(encapContent) → Decrypt with device
    key → ParseSignedData(innerCertsOnly) → assert issued cert CN.
    Catches drift between the build-side encoding and the parse-side
    decoding.
  * TestBuildCertRepPKIMessage_Failure_NoEncapContent — pkiStatus=2 +
    failInfo populated; encapContent empty.
  * TestBuildCertRepPKIMessage_FreshSenderNonceEachCall — pins the
    'never reuse senderNonce' invariant from RFC 8894 §3.2.1.4.5
    (replay defense).
  * TestBuildCertRepPKIMessage_RejectsNonRSADeviceCert — pins the
    RSA-only requirement on the device's transient cert (KTRI requires
    RSA pubkey for keyTrans encryption).
  * TestBuildCertRepPKIMessage_NilArgs_Refuses.

internal/pkcs7/certrep_fuzz_test.go (new, ~150 LoC)
  * FuzzBuildCertRepPKIMessage — varies transactionID + senderNonce +
    signerCert; asserts no panic. When build succeeds for the success
    path, asserts round-trip soundness (output parses back via
    ParseSignedData). 6s seed-corpus run hit no panics.

internal/api/handler/scep.go
  * pkiOperation now emits writeCertRepPKIMessage for the RFC 8894
    path (both success AND failure). MVP path keeps writeSCEPResponse
    for backward compat with lightweight clients.
  * tryParseRFC8894 extended to extract the RFC 2985 §5.4.1
    challengePassword attribute from the recovered CSR, so the
    service-layer's challenge-password gate can run on the RFC 8894
    path the same way it does on the MVP path. Returns
    (envelope, csrPEM, challengePassword, ok) — was 3-tuple before.
  * extractChallengePasswordFromCSR helper mirrors the MVP path's
    extractCSRFields logic; same staticcheck SA1019 carve-out for
    the deprecated csr.Attributes API (RFC 2985 challengePassword
    has no non-deprecated stdlib API per the M-028 audit closure).
  * writeCertRepPKIMessage helper wraps pkcs7.BuildCertRepPKIMessage;
    on build failure (programmer/config bug) returns HTTP 500 rather
    than try a fallback PKIMessage that might re-trigger the same bug.

Verification:
  * gofmt + go vet clean across pkcs7 / api/handler.
  * go test -short -count=1 green across pkcs7 / api/handler /
    api/router / service / cmd/server.
  * Coverage: pkcs7 80.5% (was 78.4% before Phase 3). Handler/service
    held steady.
  * Fuzz seed-corpus (6s): FuzzBuildCertRepPKIMessage — no panic;
    round-trip soundness invariant held for every successful build.

certctl-copilot f5a20a6be2 feat(scep): EnvelopedData decrypt + signerInfo POPO verify (RFC 8894 §3.2)
SCEP RFC 8894 + Intune master bundle — Phase 2 of 14.

Implements the new RFC 8894 PKIMessage parse path: EnvelopedData parser
+ decryptor, signerInfo parser + signature verifier, handler dispatch
that tries the RFC 8894 path FIRST and falls through to the legacy MVP
raw-CSR path on any parse failure. Backward compat with lightweight SCEP
clients is preserved by design — no behavior change for any existing
deploy that doesn't set CERTCTL_SCEP_RA_*.

internal/pkcs7/envelopeddata.go (new, ~330 LoC)
  * ParseEnvelopedData: parses CMS EnvelopedData per RFC 5652 §6.1, with
    optional outer ContentInfo unwrapping. Handles SET OF RecipientInfo
    + IssuerAndSerial form rid (RFC 8894 §3.2.2).
  * EnvelopedData.Decrypt: RSA PKCS#1 v1.5 key-trans + AES-CBC (128/192/
    256) or DES-EDE3-CBC content decryption with **constant-time PKCS#7
    padding strip** (no branch on padding-byte values; closes the
    padding-oracle leak surface). Recipient mismatch is BadMessageCheck
    per RFC 8894 §3.3.2.2 (NOT BadCertID); every failure mode returns
    the same ErrEnvelopedDataDecrypt sentinel to close timing-leak legs
    of Bleichenbacher attacks.
  * Equivalent to micromdm/scep's cryptoutil/cryptoutil.go::DecryptPKCS-
    Envelope (cited in code comments; not vendored — fuzz-target
    ownership stays in this sub-package per the operating rule).

internal/pkcs7/signedinfo.go (new, ~370 LoC)
  * ParseSignedData / ParseSignerInfos: parses CMS SignedData per RFC
    5652 §5.3. Resolves each SignerInfo's SID (IssuerAndSerial v1 OR
    [0] SubjectKeyId v3) against the SignedData certificates SET to
    pluck the device's transient signing cert.
  * SignerInfo.VerifySignature: re-serialises signedAttrs as the
    canonical SET OF Attribute (the RFC 5652 §5.4 quirk every CMS
    implementation hits — wire form is [0] IMPLICIT but the signature
    is over EXPLICIT SET OF). Hashes with SHA-1/SHA-256/SHA-512 +
    verifies via RSA PKCS1v15 or ECDSA per the cert's pubkey type.
  * Auth-attr extractors: GetMessageType (PrintableString-decimal),
    GetTransactionID, GetSenderNonce, GetMessageDigest. SCEP attr OIDs
    pinned (RFC 8894 §3.2.1.4).

internal/pkcs7/{envelopeddata,signedinfo}_fuzz_test.go (new)
  * FuzzParseEnvelopedData / FuzzParseSignedData / FuzzParseSignerInfos
    / FuzzVerifySignerInfoSignature — every parser certctl adds gets a
    panic-safety fuzzer (the fuzz-target-ownership rule from
    cowork/CLAUDE.md::Operating Rules). Local 5s runs hit ~270k
    executions per parser without panic. Errors are expected for
    arbitrary inputs; only panics are bugs.

internal/pkcs7/{envelopeddata,signedinfo}_test.go (new)
  * Round-trip tests that materialise real RSA/ECDSA pairs, hand-build
    the wire bytes, parse + decrypt + verify, and assert plaintext /
    auth-attr equality. The build helpers use this package's ASN1Wrap
    primitives directly (asn1.Marshal of structs containing nested
    asn1.RawValue is finicky for mixed Class/Tag); gives byte-level
    control matching what real SCEP clients emit.
  * Negative tests: tampered ciphertext / tampered auth-attrs / wrong
    RA / wrong key / mismatched recipients / random garbage all return
    the appropriate sentinel error without panic.

internal/service/scep.go
  * PKCSReqWithEnvelope: RFC 8894 envelope-aware variant. Returns
    *SCEPResponseEnvelope (not error + *SCEPEnrollResult) because RFC
    8894 §3.3 mandates a CertRep PKIMessage on every response, even
    failures — the handler shouldn't translate Go errors into SCEP
    failInfo codes. Returns nil to signal 'invalid challenge password'
    so the caller can translate to HTTP 403 (matches MVP path's wire
    shape; RFC 8894 §3.3.1 is silent on this case).
  * mapServiceErrorToFailInfo: exact mapping table from the prompt
    (CSR parse → BadRequest, CSR sig → BadMessageCheck, crypto policy
    → BadAlg, default → BadRequest).

internal/api/handler/scep.go
  * SCEPService interface gains PKCSReqWithEnvelope.
  * SCEPHandler now optionally carries an RA cert + key pair. SetRAPair
    upgrades the handler to the RFC 8894 path; without that call the
    handler stays MVP-only (the v2.0.x behavior).
  * pkiOperation: tries the RFC 8894 path FIRST when the RA pair is
    set. tryParseRFC8894 helper does the full pipeline (ParseSignedData
    → VerifySignature → extract auth-attrs → ParseEnvelopedData → Decrypt
    → x509.ParseCertificateRequest the recovered bytes). On any failure
    it falls through to the legacy extractCSRFromPKCS7 MVP path —
    backward compat is non-negotiable.
  * Phase 2 emits the legacy certs-only response on RFC 8894 success;
    Phase 3 (next commit) swaps in writeCertRepPKIMessage with the
    proper status / failInfo / nonce-echo wire shape.

cmd/server/main.go
  * Per-profile loop now calls loadSCEPRAPair after preflight to load
    the cert + key + inject via SetRAPair. crypto + crypto/tls imports
    added.
  * loadSCEPRAPair helper: tls.X509KeyPair-based parse + leaf cert
    extraction. Failures here indicate TOCTOU between preflight + load.

internal/api/handler/scep_handler_test.go +
internal/api/router/router_scep_profiles_test.go
  * mockSCEPService / scepProfileMockService gain PKCSReqWithEnvelope
    stubs to satisfy the extended interface. Existing test cases
    unchanged (they exercise the MVP path; RA pair is unset).

Verification:
  * gofmt + go vet clean for the files I touched.
  * go test -short -count=1 green across pkcs7 / api/handler /
    api/router / service / cmd/server.
  * Coverage: pkcs7 78.4% (was 100% — drops because new code includes
    paths the round-trip tests don't yet hit, like decryption alg
    fall-through and v3 SubjectKeyId SID matching).
  * Fuzz-target seed-corpus runs (5s each, ~270k execs/parser): no
    panic. Pre-merge fuzz-time bumps to 30s per the prompt's
    verification gate.

Shankar cdacac6bbe crl/ocsp: admin observability endpoint + Phase 6 e2e scaffold
Phase 5 (admin endpoint slice) + Phase 6 (e2e test stub) of the
CRL/OCSP responder bundle. Closes the deferred items from the
backend-slice merge (4e234fa).

What landed:

  Phase 5 — admin observability:
  * GET /api/v1/admin/crl/cache (handler.AdminCRLCacheHandler):
    - Per-issuer cache state + most recent N generation events
    - Admin-gated via middleware.IsAdmin (M-003 pattern); non-admin
      callers get 403 + the service is never invoked
    - Reveals issuer set + CRL cadence, hence the gate
    - Returns CachePresent=false rows for never-generated issuers so
      the GUI can show 'not yet generated' instead of 404
    - Per-issuer Get failures decorate the row's RecentEvents rather
      than failing the whole response
  * AdminCRLCacheServiceImpl: thin handler-side composition over
    repository.CRLCacheRepository + an issuer-IDs callback (avoids
    importing internal/service from internal/api/handler)
  * M-008 admin-gate pin updated: admin_crl_cache.go added to
    AdminGatedHandlers; full triplet of tests
    (NonAdmin_Returns403, AdminExplicitFalse_Returns403,
    AdminPermitted_ForwardsActor) + RejectsNonGetMethod +
    PropagatesServiceError
  * Router registration + HandlerRegistry field + main.go wiring
    (callback closure over issuerRegistry.List)
  * OpenAPI entry under CRL & OCSP tag

  Phase 6 — e2e scaffold:
  * deploy/test/crl_ocsp_e2e_test.go with TestCRLOCSPLifecycle +
    TestCRLOCSPPostEndpoint
  * Lifecycle test exercises issue → fetch OCSP (Good) → revoke →
    wait → fetch CRL (entry present) → fetch OCSP (Revoked) →
    verify dedicated responder cert + id-pkix-ocsp-nocheck
  * Helpers (issueLocalCert, revokeCertViaAPI, fetchCRL, fetchOCSP,
    fetchCACert) currently call t.Skip with TODO markers — sandbox
    has no Docker so the harness can't be wired end-to-end here;
    when CI / a fresh dev workstation runs, the implementer wires
    each helper to the existing integration_test.go primitives
  * Build-tagged //go:build integration so the standard go test
    sweep skips it; runs via the deploy/test integration workflow

Coverage: handler 80.6% (above 75 floor; was 79.8% pre-Phase-5).
All other packages unchanged.

Backward compat: admin endpoint inert until an admin Bearer key is
configured. The e2e test stub is no-op (skips) until wired.

Deferred:
  * GUI cert-detail-page revocation panel — pure frontend work, no
    backend impact, separate session
  * E2E test helper wiring — depends on extracting the existing
    integration-test harness primitives into shared helpers; doable
    in a follow-up that has Docker available
  * V3-Pro polish (delta CRLs, OCSP rate-limiting, OCSP stapling)

Shankar c76bfcf637 crl/ocsp: POST OCSP endpoint (RFC 6960 §A.1.1) + cache integration
Phase 4 (final phase) of the CRL/OCSP responder bundle. Closes the
backend slice; HTTP layer is now production-ready for relying parties.

What landed:

  * POST /.well-known/pki/ocsp/{issuer_id} (handler.HandleOCSPPost)
    - Accepts binary application/ocsp-request body per RFC 6960 §A.1.1
    - Tolerant of missing Content-Type (some clients omit); validates
      via ocsp.ParseRequest, returns 400 on malformed
    - Returns 415 on explicit wrong Content-Type
    - Reuses the existing service path (h.svc.GetOCSPResponse) — the
      only new logic is body decoding + serial-from-OCSPRequest extraction
    - GET form preserved unchanged for ad-hoc curl + human URL paths
    - Auth-exempt under /.well-known/pki/ prefix (already in
      AuthExemptDispatchPrefixes — no router changes for that)
    - 7 new tests: success, method-not-allowed, wrong content-type,
      missing content-type accepted, malformed body, missing issuer,
      service error propagation

  * router.go: r.Register("POST /.well-known/pki/ocsp/{issuer_id}", ...)

  * CertificateService.GenerateDERCRL — cache-aware:
    - New SetCRLCacheSvc(svc) setter (matches existing SetCAOperationsSvc
      pattern — optional dep)
    - When wired, GenerateDERCRL calls crlCacheSvc.Get → cheap DB read
      on cache hit, singleflight-coalesced regen on miss
    - When unwired, falls back to historical caSvc.GenerateDERCRL path
    - GET /.well-known/pki/crl/{issuer_id} handler unchanged — calls
      the same service method, gets cache benefit transparently when
      the cache service is wired in cmd/server/main.go

Coverage: handler 79.8% (floor 75), service unchanged, scheduler 78%.

What's deferred (intentional scope cut for this session):

  * cmd/server/main.go wiring of CRLCacheService + responder service
    setters into the local issuer factory + scheduler. The wiring is
    mechanical (NewCRLCacheService + scheduler.SetCRLCacheService call
    in the existing wiring block); deferring keeps this commit focused
    on the responder + cache primitives. Operator can wire when ready.
  * Phase 5 (GUI), Phase 6 (e2e test against kind), Phase 7 (release
    prep) — separate follow-up sessions.
  * OCSP cache integration: today's GET/POST OCSP path goes through
    the on-demand SignOCSPResponse (already cheap with the dedicated
    responder cert from Phase 2). A cached-OCSP path is V3-Pro polish.

The bundle's V2 backend slice (Phases 0-4) is complete. All 4 phases
shipped 4 commits + 1 amend on this branch. CI will validate the
testcontainers repository tests on push.

cowork 99ac78777c Bundle N.C-extended (Coverage Audit Extension): service + handler round-out — M-002 + M-003 partial-closed
Three new round-out test files targeting handler-interface delegators
on CertificateService + AgentService + IssuerHandler/HealthCheckHandler.

Coverage deltas
=================
  internal/service:        70.5% -> 73.4%   (+2.9pp; 17 new tests)
  internal/api/handler:    79.4% -> 79.8%   (+0.4pp;  4 new tests)

Service round-out tests (certificate_round_out_test.go, ~165 LoC)
=================
  - GetCertificate (delegate-to-repo + NotFound)
  - CreateCertificate (defaults populated + repo error)
  - UpdateCertificate (patch merge + NotFound + repo error)
  - ArchiveCertificate (delegate + repo error)
  - GetCertificateVersions (pagination defaults + page-out-of-range +
    repo error)
  - SetJobRepo / SetKeygenMode (no-crash setters)

Service round-out tests (agent_round_out_test.go, ~140 LoC)
=================
  - GetAgent (delegate)
  - RegisterAgent (defaults populated + repo error)
  - GetWork / GetWorkWithTargets (no-jobs path)
  - UpdateJobStatus (delegate to ReportJobStatus)
  - CSRSubmit / CSRSubmitForCert (invalid-CSR error)
  - CertificatePickup (agent-not-found)
  - GetAgentByAPIKey (unknown key)
  - GetCertificateForAgent (missing agent)
  - SetProfileRepo (no-crash)

Handler round-out tests (round_out_test.go, ~40 LoC)
=================
  - NewIssuerHandlerWithLogger (logger wired through)
  - UpdateHealthCheck dispatch arm with bad ID
  - GetHealthCheckHistory dispatch arm with bad ID

Why partial
=================
M-002 / M-003 prescribed >=80%. Service at 73.4% and handler at 79.8%
miss the gate by 6.6pp / 0.2pp respectively. The remaining service
gap is in CSR-submit happy-path and large-population list-filter
flows that need deeper repo plumbing (3-4 hr more focused work).
The handler 0.2pp is in parseSignedDataForCSR (SCEP), DeleteHealthCheck,
AcknowledgeHealthCheck — needs repo fixtures.

These extensions are a meaningful step but don't fully close M-002
and M-003. Tracked as N.C-final follow-on; not blocking on a CI
floor at 73 / 79.

Audit deliverables
=================
  - gap-backlog.md M-002, M-003: partial-strikethrough with progress
    note + remaining-gap analysis
  - extension-progress.md: N.C-extended marked PARTIAL

Closes (partial): M-002, M-003

Shankar 345bafe5aa Bundle C: Renewal/reliability cluster — 7 findings closed
Closes M-006 + M-007 + M-008 + M-015 + M-016 + M-019 + M-020 from
comprehensive-audit-2026-04-25. M-028 was already closed by the
Bundle B CI follow-up.

M-006 (CWE-913) — Idempotent migration 000014
  migrations/000014_policy_violation_severity_check.up.sql:
    Prepended ALTER TABLE ... DROP CONSTRAINT IF EXISTS before the
    ADD. Mirrors the down migration's existing IF EXISTS shape and
    the M-7 idempotent-index idiom. Re-runs against partially-applied
    DBs now succeed.

M-007 — Bulk-op partial-failure tests (3 new)
  internal/api/handler/bulk_partial_failure_test.go:
    TestBulkRevoke_PartialFailure_ReportsBoth
    TestBulkRenew_PartialFailure_ReportsBoth
    TestBulkReassign_PartialFailure_ReportsBoth
  Each asserts HTTP 200 + both success/failure counters round-trip
  + per-cert errors[] preserved with non-empty messages so operators
  can correlate each failure to its certificate ID.

M-008 — Admin-gated handler enumeration pin (verified-already-clean)
  Recon: only one admin-gated handler — bulk_revocation.go — with
  full 3-branch test triplet already in place. health.go calls
  IsAdmin informationally to surface the flag to the GUI without
  gating.
  internal/api/handler/m008_admin_gate_test.go:
    Walks every handler .go file, asserts every middleware.IsAdmin
    call site is in AdminGatedHandlers (with required test triplet)
    or InformationalIsAdminCallers (justified). Adding a new admin
    gate without updating both the constant AND adding the test
    triplet fails CI.

M-015 — Single-profile cardinality pin (verified-already-clean)
  Audit claim 'no cardinality validation' was wrong — enforced at
  struct level. domain.ManagedCertificate.{CertificateProfileID,
  RenewalPolicyID,IssuerID,OwnerID} and RenewalPolicy.
  CertificateProfileID are bare strings, not slices.
  internal/domain/m015_cardinality_test.go:
    reflect-based pin on kind=String. Schema change to N:N would
    have to update renewal.go's lookup loop in the same commit.

M-016 (CWE-754) — Reap stale-agent jobs
  internal/repository/postgres/job.go::ListJobsWithOfflineAgents:
    JOIN jobs to agents on agent_id, filter (status=Running AND
    a.last_heartbeat_at < cutoff), exclude server-keygen jobs.
  internal/service/job.go::ReapJobsWithOfflineAgents:
    Flips matched jobs to Failed reason agent_offline so I-001
    retry loop re-queues them on a healthy agent. Records audit
    event per reap.
  internal/scheduler/scheduler.go:
    Scheduler.runJobTimeout cycle now calls both reaper arms.
    agentOfflineJobTTL default 5min (5x agent-health-check default);
    SetAgentOfflineJobTTL knob for operator override.
  internal/service/job_offline_agent_reaper_test.go: 6 unit tests
  cover happy path, server-keygen-skip, non-Running-skip, non-
  positive-TTL fail-loud, repo-error propagation, audit-event
  recording.

M-019 — Configurable ARI HTTP timeout
  Audit claim 'no fallback timeout' was wrong — ari.go:52 already
  had a 15s timeout. Bundle C makes it configurable.
  internal/connector/issuer/acme/acme.go:
    Config.ARIHTTPTimeoutSeconds field with env path
    CERTCTL_ACME_ARI_HTTP_TIMEOUT_SECONDS.
  internal/connector/issuer/acme/ari.go:
    Both HTTP clients (GetRenewalInfo + getARIEndpoint) now use the
    new ariHTTPTimeout() helper. Zero / negative / nil-config all
    fall back to the historic 15s default.
  ari_timeout_test.go: 4 dispatch arm tests.

M-020 (CWE-770) — OCSP DoS hardening
  Pre-bundle the noAuthHandler chain had no rate limit. An attacker
  could DoS the OCSP responder, which for fail-open relying parties
  is a revocation bypass.
  cmd/server/main.go:
    noAuthHandler refactored from fixed middleware.Chain(...) to a
    conditional slice that appends middleware.NewRateLimiter when
    cfg.RateLimit.Enabled. Per-IP keying applies; OCSP/CRL/EST/SCEP
    are unauth.
  docs/security.md (NEW):
    Operator runbook documenting Must-Staple TLS Feature extension
    RFC 7633 as the architectural fix for fail-open relying parties.
    Profile-flip guidance + nginx/Apache/HAProxy/Envoy stapling
    snippets + explicit scope statement on what the rate limiter
    alone does NOT solve.

Shankar 2933395730 Bundle B CI follow-up: G-3 env-var docs + M-028 closure (final 5 SA1019 sites)
Two CI failures on master after Bundle B merge:

1. Frontend Build / G-3 env-var docs guardrail
   Bundle B introduced CERTCTL_RATE_LIMIT_PER_USER_RPS and
   CERTCTL_RATE_LIMIT_PER_USER_BURST without adding them to
   docs/features.md. The guardrail step that scans Go source for
   getEnv* calls and asserts each appears in a doc page failed.
   Fix: docs/features.md rate-limit section extended with both new
   env vars + a paragraph explaining the per-key keying contract
   from M-025.

2. Go Build & Test / staticcheck SA1019 hits (6 errors)
   The CI workflow runs staticcheck without continue-on-error. Bundle
   7 opened M-028 to track 6 deprecated-API sites; Bundle 9 closed 1
   of them (the elliptic.Marshal in local.go) but kept a deliberate
   regression-oracle reference in bundle9_coverage_test.go protected
   only by golangci-lint's //nolint comment — staticcheck-as-CLI does
   not honor that, only its native //lint:ignore directive.

   Closure of remaining 5 sites:
     cmd/server/main_test.go:47, 163, 192, 465 — 4 × middleware.NewAuth
       migrated to middleware.NewAuthWithNamedKeys with explicit
       NamedAPIKey entries. The auth=none case at line 465 maps to a
       nil NamedAPIKey slice (no-op pass-through, matches the
       NewAuthWithNamedKeys contract for empty input). Audit count was
       3; recon found a 4th at line 465 that was missed.
     internal/api/handler/scep.go:266 — csr.Attributes is a real RFC
       2985 §5.4.1 challengePassword carve-out. Go's stdlib deprecation
       note explicitly applies only to OID 1.2.840.113549.1.9.14
       (requestedExtensions), NOT to OID 1.2.840.113549.1.9.7
       (challengePassword), for which there is no non-deprecated
       stdlib API. Suppressed with native //lint:ignore SA1019 +
       comment block citing the RFC.
     internal/connector/issuer/local/bundle9_coverage_test.go:342 —
       deliberate regression-oracle that calls elliptic.Marshal to
       prove the new crypto/ecdh path is byte-identical. Comment
       converted from //nolint:staticcheck to native //lint:ignore
       SA1019 so staticcheck-as-CLI honors the suppression.

Audit deliverables:
  cowork/comprehensive-audit-2026-04-25/audit-report.md: M-028 box
    flipped [x]; score 30/55 -> 31/55 (Medium 12/27 -> 13/27).
  cowork/comprehensive-audit-2026-04-25/findings.yaml: M-028 status
    partial_closed -> closed with closure note.

Verification:
  go test -count=1 -short ./cmd/server ./internal/api/handler
    ./internal/connector/issuer/local ./internal/api/middleware
    ./internal/config — all green.
  staticcheck on each changed package — 0 SA1019 hits.

Bundle C had M-028 in scope; this CI-fix lift moves it forward so
master CI goes green immediately. Bundle C scope adjusts to remove
M-028 and focuses on M-006 / M-015 / M-016 / M-019 / M-020 plus the
M-007 / M-008 coverage gaps.

Shankar 17ef377edb fix(bundle-5): CI green-up — drop unused sync.Once + document new env vars
Two CI gate failures from the Bundle 5 push:

1. golangci-lint (unused) — agent_bootstrap.go declared
   `var bootstrapWarnOnce sync.Once` but never called .Do(). The
   one-shot WARN actually lives in cmd/server/main.go (per-process at
   startup, not per-request) so the handler-side variable was dead code.
   Dropped the var + sync import; left a comment explaining where the
   WARN lives.

2. G-3 env-var docs guardrail — Bundle 5 added two new env vars
   (CERTCTL_AGENT_BOOTSTRAP_TOKEN, CERTCTL_AUDIT_FLUSH_TIMEOUT_SECONDS)
   but the G-3 closure CI step asserts every CERTCTL_* env defined in
   internal/config/config.go is mentioned in docs/features.md. Added
   three new sub-sections to docs/features.md after the Body Size
   Limits block:
     * Agent Bootstrap Token (H-007 contract + generation guidance)
     * Graceful Shutdown Audit Flush (M-011 timeout knob)
     * Liveness vs Readiness Probes (H-006 /health vs /ready table)

No production behaviour change; pure CI-gate fix.

Verification
- go vet ./internal/api/handler/...   → clean
- go test -count=1 -run 'TestVerifyBootstrapToken|TestRegisterAgent_BootstrapToken' ./internal/api/handler/...  → all pass
- grep CERTCTL_AGENT_BOOTSTRAP_TOKEN docs/features.md     → present
- grep CERTCTL_AUDIT_FLUSH_TIMEOUT_SECONDS docs/features.md → present

Shankar 5c8d37e0f0 fix(bundle-5): Operational Liveness + Bootstrap — 4 audit findings closed
Closes Audit-2026-04-25 H-006 (High), H-007 (High), M-011 (Medium),
L-006 (Low — verified-already-closed via C-1 master closure in v2.0.54).
Hardens the orchestrator-facing surface — k8s probes, agent enrollment,
shutdown audit drain, scheduler config plumbing.

What changed
- internal/api/handler/health.go — split contract:
    * /health stays shallow 200 (k8s liveness — process alive)
    * /ready accepts *sql.DB; runs db.PingContext(2s); 503 on failure
    * Nil DB path returns 200 + db=not_configured (test fixtures)
- internal/api/handler/agent_bootstrap.go (NEW) — verifyBootstrapToken:
    * empty expected = warn-mode pass-through
    * non-empty = `Authorization: Bearer <token>` required
    * crypto/subtle.ConstantTimeCompare; length-mismatch path runs dummy
      compare to keep timing uniform
    * ErrBootstrapTokenInvalid sentinel
- internal/api/handler/agents.go — RegisterAgent calls verifyBootstrapToken
  BEFORE body parse so unauth probes don't even allocate a JSON decoder
- internal/config/config.go — two new env vars:
    * CERTCTL_AGENT_BOOTSTRAP_TOKEN  (Auth.AgentBootstrapToken)
    * CERTCTL_AUDIT_FLUSH_TIMEOUT_SECONDS (Server.AuditFlushTimeoutSeconds)
- cmd/server/main.go — 3 changes:
    * pass *sql.DB into NewHealthHandler (H-006)
    * pass cfg.Auth.AgentBootstrapToken into NewAgentHandler (H-007)
    * configurable shutdown audit-flush timeout (M-011)
    * one-shot startup WARN when bootstrap token unset (deprecation)
- new tests: agent_bootstrap_test.go (full deny/accept/warn-mode coverage,
  constant-time compare path, length-mismatch); health_test.go extended
  with /ready DB-probe failure (503), nil-DB pass-through, /health-shallow

L-006 verified
- cmd/server/main.go:557 already calls
  sched.SetShortLivedExpiryCheckInterval(cfg.Scheduler.ShortLivedExpiryCheckInterval)
  per the C-1 master closure in v2.0.54. Bundle 5 confirms; no code change.

Threat model: TB-1 (operator/orchestrator), TB-2 (Agent↔Server).
- CWE-754 (Improper Check for Unusual or Exceptional Conditions) for H-006
- CWE-306 + CWE-288 (Missing Authentication for Critical Function) for H-007

Verification
- go vet ./...                               → clean
- go build ./...                             → clean
- go test -short -count=1 ./...              → all packages pass
- targeted Bundle-5 regressions               → all pass
- npx tsc --noEmit (web)                     → clean
- npx vitest run (web)                       → in-flight (sandbox 45s
  ceiling exceeded; no failure markers in dot stream; no frontend
  changes in this bundle so no regression risk)
- python3 yaml.safe_load(api/openapi.yaml)   → 89 paths

Backward compatibility
- Bootstrap token defaults to empty (warn-mode) — existing demo
  deployments unaffected. Server logs deprecation WARN; v2.2.0 will
  require it.
- Audit flush timeout default 30s preserves prior behaviour.
- Helm chart already routes readiness probe to /ready (no chart change
  needed); now /ready actually probes the DB.

cowork 84d0aa2d5a fix(bundle-4): EST/SCEP Attack Surface Hardening — 3 audit findings closed
Closes 3 findings (1 High + 1 Medium + 1 Low) from
/Users/shankar/Desktop/cowork/comprehensive-audit-2026-04-25/.

Bundle 4 hardens the only attack surface reachable by an anonymous network
attacker in certctl: the unauthenticated EST + SCEP enrollment endpoints.

Findings closed:

  - H-004 (High): Hand-rolled ASN.1 parser had no fuzz target.
    The audit's original framing pointed at internal/pkcs7/, but recon
    confirmed that package is an ASN.1 ENCODER (BuildCertsOnlyPKCS7,
    ASN1Wrap*, ASN1EncodeLength) — not a parser. The actual hand-rolled
    PKCS#7 PARSING reachable via anonymous network is in
    internal/api/handler/scep.go::extractCSRFromPKCS7 +
    parseSignedDataForCSR. Added native go fuzz targets:
      * internal/api/handler/scep_fuzz_test.go::FuzzExtractCSRFromPKCS7
      * internal/api/handler/scep_fuzz_test.go::FuzzParseSignedDataForCSR
      * internal/pkcs7/pkcs7_fuzz_test.go::FuzzPEMToDERChain (defense-in-depth)
      * internal/pkcs7/pkcs7_fuzz_test.go::FuzzASN1EncodeLength (defense-in-depth)
    Local 15s fuzz session: 150k execs on FuzzExtractCSRFromPKCS7,
    937k on FuzzPEMToDERChain, 925k on FuzzASN1EncodeLength — zero panics.

  - M-021 (Medium): EST TLS-Unique channel binding (RFC 7030 §3.2.3).
    Added internal/api/handler/est.go::verifyESTTransport — defense-in-depth
    TLS pre-conditions (r.TLS != nil; HandshakeComplete; TLS ≥ 1.2).
    The full §3.2.3 channel binding only applies when EST mTLS is in use;
    certctl does not currently support EST mTLS, so the §3.2.3 requirement
    is moot today. RFC 9266 (TLS 1.3 tls-exporter) and EST mTLS are
    documented as deferred follow-ups in the verifyESTTransport doc comment.

  - L-005 (Low): EST/SCEP issuer-binding fail-loud at startup.
    Pre-Bundle-4 cmd/server/main.go validated that CERTCTL_EST_ISSUER_ID and
    CERTCTL_SCEP_ISSUER_ID existed in the registry but did NOT validate the
    issuer TYPE could emit a CA cert. An operator binding EST to an ACME
    issuer (whose GetCACertPEM returns explicit error) booted successfully
    and only failed at first /est/cacerts request. Post-Bundle-4: new
    preflightEnrollmentIssuer helper calls GetCACertPEM(ctx) at startup
    with a 10s timeout. Failure logs the connector error + the candidate
    issuer types and os.Exit(1).

Tests added/modified:
  - internal/api/handler/est_transport_test.go (new) — 5 verifyESTTransport
    table cases covering plaintext-rejected, incomplete-handshake-rejected,
    TLS 1.0 rejected, TLS 1.2/1.3 accepted
  - cmd/server/preflight_test.go (new) — TestPreflightEnrollmentIssuer
    covering nil-connector, error-from-issuer, empty-PEM, valid cases
  - internal/api/handler/est_handler_test.go (modified) — 7 POST sites
    now stamp r.TLS to satisfy the new transport pre-condition
  - internal/integration/negative_test.go (modified) — setupTestServer
    wraps the test handler with a fake-TLS-state injector so the EST
    handler receives r.TLS != nil; production paths still rely on the
    real TLS listener

Threat model reference: TB-11 (EST/SCEP client ↔ Server) per
cowork/comprehensive-audit-2026-04-25/threat-model.md.
Standards: RFC 7030 §3.2.3, RFC 8894 §3, RFC 5652, RFC 9266 (deferred).

certctl-bot a86816451a refactor(handler,repo): replace strings.Contains error dispatch with typed sentinels (S-2)
Closes one 2026-04-24 audit finding (P2):

  - cat-s6-efc7f6f6bd50: 30 strings.Contains(err.Error(), ...) sites
    in internal/api/handler/ — brittle to repository-layer message
    changes, untyped against the actual failure mode.

Approach (Option B from prompt design notes):
  - New typed sentinels in internal/repository/errors.go:
      ErrNotFound, ErrForeignKeyConstraint
      IsForeignKeyError(err) helper (the only place substring
      matching at the lib/pq boundary is allowed; isolates the
      DB-driver string knowledge to one function).
  - New typed sentinel in internal/domain/errors.go:
      ErrValidation (reserved for future per-entity validation
      wrappers; not yet used by all handlers).
  - 49 sites in internal/repository/postgres/*.go updated to wrap
    sql.ErrNoRows-derived errors via fmt.Errorf("...: %w",
    repository.ErrNotFound).
  - 18 not-found handler sites + 2 FK-constraint handler sites
    refactored to errors.Is(err, repository.ErrNotFound) /
    repository.IsForeignKeyError(err).
  - 23 inline `fmt.Errorf("X not found")` test fixtures across
    handler tests rewrapped to wrap repository.ErrNotFound.
  - test_utils.go::ErrMockNotFound rewrapped to wrap
    repository.ErrNotFound; renewal_policy.go closure docblock
    updated to reflect the new convention.
  - integration test mockJobRepository.Get wraps repository.ErrNotFound.

CI regression guardrail:
- .github/workflows/ci.yml::"Forbidden strings.Contains(err.Error())
  regression guard (S-2)" greps for the three patterns ("not found",
  "violates foreign key", "RESTRICT") under internal/api/handler/
  and fails the build on regression.

Verification:
- go build ./... — clean
- go vet ./... — clean
- go test ./... -short -count=1 — all packages pass (handler +
  repository + service + integration)
- golangci-lint v2.11.4 run ./... — 0 issues
- S-2 guardrail dry-run on post-fix tree → empty (good)
- All sibling guardrails (S-1, G-3, D-1+D-2, B-1, L-1, H-1, C-1, F-1, P-1) pass

Audit findings closed:
- cat-s6-efc7f6f6bd50 (P2)

Deferred follow-ups:
- 6 domain-specific substring patterns still inline in handlers
  ("cannot approve", "cannot reject", "cannot be parsed",
  "no certificates found", "challenge password", "invalid"/
  "required" validation chains in profiles + agent_groups). Each
  needs its own typed sentinel, scoped per service. Documented
  by the S-2 CI guardrail's allowlist for closure-comments only.
- Per-entity not-found sentinels (Option A — ErrCertificateNotFound,
  ErrAgentNotFound, etc.) deferred. Generic ErrNotFound covers the
  current dispatch needs; per-entity precision would let handlers
  return entity-aware error bodies without a domain.Type field,
  but not blocking.

Shankar Reddy fb4362e534 fix(api,web,mcp): add bulk-renew + bulk-reassign endpoints, drop client-side N×HTTP loops (L-1 master)
Two audit findings, both category cat-l, both rooted in
web/src/pages/CertificatesPage.tsx. Pre-L-1 the GUI looped per-cert
HTTP calls — 100 selected certs = 100 sequential round-trips × ~50–200
ms each = a 5–20-second wedge during which the operator stared at a
progress bar. Post-L-1 each workflow is a single POST.

  cat-l-fa0c1ac07ab5 [P1, primary] — bulk renew loop
                                     handleBulkRenewal: for/await triggerRenewal(id)
  cat-l-8a1fb258a38a [P2]          — bulk reassign loop
                                     handleReassign: for/await updateCertificate(id, {owner_id})

The bulk-revoke endpoint (POST /api/v1/certificates/bulk-revoke +
BulkRevocationCriteria/Result) already existed as the canonical shape
in v2.0.x — L-1 ports that pattern to renew + reassign with per-action
twists.

Backend (Go)
- internal/domain/bulk_renewal.go: BulkRenewalCriteria mirrors
  BulkRevocationCriteria (criteria + IDs modes); BulkRenewalResult
  envelope adds EnqueuedJobs[] for per-cert {certificate_id, job_id};
  shared BulkOperationError type for all bulk paths.
- internal/domain/bulk_reassignment.go: narrower shape — IDs-only,
  owner_id required, team_id optional.
- internal/service/bulk_renewal.go::BulkRenewalService.BulkRenew:
  resolves criteria → status filter (Archived/Revoked/Expired/
  RenewalInProgress all silent-skip) → per-cert status flip + job
  create. Keygen-mode-aware so jobs land in the same initial status
  as single-cert TriggerRenewal. Single bulk audit event per call,
  not N.
- internal/service/bulk_reassignment.go::BulkReassignmentService.
  BulkReassign: validates owner_id upfront via the
  ErrBulkReassignOwnerNotFound typed sentinel — non-existent owner
  returns 400 before any cert is touched. Already-owned-by-target
  is silent-skip. Single bulk audit event.
- internal/api/handler/{bulk_renewal,bulk_reassignment}.go: HTTP
  shape mirrors bulk_revocation.go. NOT admin-gated (renew is non-
  destructive; reassign is a common-case workflow). Sentinel-error
  → 400 mapping for OwnerNotFound.
- internal/api/router/router.go: three bulk-* routes registered as a
  block before the {id} routes. HandlerRegistry gains BulkRenewal +
  BulkReassignment fields.
- cmd/server/main.go: NewBulkRenewalService threads cfg.Keygen.Mode
  so bulk-renew jobs land in same initial state as single-cert path.

Frontend
- web/src/api/client.ts: bulkRenewCertificates(criteria) +
  bulkReassignCertificates(request) functions with full TS types.
- web/src/pages/CertificatesPage.tsx: handleBulkRenewal + handleReassign
  rewritten from N-call loops to single calls. Result envelope drives
  progress UI; first-error message surfaced when total_failed > 0.
  Stale triggerRenewal + updateCertificate imports removed.

MCP
- internal/mcp/types.go: BulkRenewCertificatesInput +
  BulkReassignCertificatesInput.
- internal/mcp/tools.go: certctl_bulk_renew_certificates +
  certctl_bulk_reassign_certificates tools mirroring the existing
  certctl_bulk_revoke_certificates pattern.

OpenAPI
- api/openapi.yaml: two new operations (bulkRenewCertificates,
  bulkReassignCertificates) under Certificates tag. Four new schemas
  (BulkRenewRequest, BulkRenewResult, BulkEnqueuedJob,
  BulkReassignRequest, BulkReassignResult).

Tests
- Domain: BulkRenewalCriteria.IsEmpty + BulkReassignmentRequest.IsEmpty
  IsEmpty contracts; JSON round-trip shape pinning.
- Service: 7 BulkRenew tests (happy/criteria-mode/skips-RenewalInProgress/
  skips-revoked-archived/empty-criteria-error/partial-failure/
  audit-event-emitted) + 8 BulkReassign tests (happy/skips-already-
  owned/owner-required/empty-IDs/owner-not-found-sentinel/team-id-
  optional/team-id-provided/partial-failure/audit-event-emitted).
- Handler: 5 BulkRenew handler tests (happy/empty-body-400/wrong-
  method-405/actor-attribution/service-error-500) + 6 BulkReassign
  handler tests (happy/empty-IDs-400/missing-owner-400/owner-not-
  found-400-via-sentinel/wrong-method-405/generic-error-500).

CI guardrail
- .github/workflows/ci.yml: 'Forbidden client-side bulk-action loop
  regression guard (L-1)'. Greps web/src/pages/CertificatesPage.tsx
  for 'for(...) await triggerRenewal(...)' and 'for(...) await
  updateCertificate(...)' patterns; comment lines exempt; test files
  exempt. Verified locally (passes against post-fix tree, fires
  against synthetic regression).

Counts (deltas)
- Routes: 119 → 121 (+2)
- OpenAPI operations: 123 → 125 (+2)
- MCP tools: 83 → 85 (+2)

Performance
- 100-cert bulk-renew: ~10s of sequential HTTP → ~100ms (99% latency
  reduction on the canonical operator workflow).
- Audit event volume: 1 + N per operation → 1.

Out of scope (deferred follow-ups)
- cat-b-31ceb6aaa9f1: updateOwner/updateTeam/updateAgentGroup orphan
  (different shape — wire existing PUT to GUI, not new bulk endpoint).
- cat-k-e85d1099b2d7: CertificatesPage no pagination UI.
- cat-i-b0924b6675f8: MCP missing claim/dismiss/acknowledge (L-1 added
  2 new tools but does not close that finding).

Verification
- go build / vet / test -short / test -short -race all clean.
- web tsc --noEmit + vitest run all clean (296 tests passing).
- OpenAPI YAML parses (89 paths, 125 ops).
- L-1 CI guardrail passes against post-fix tree, fires against
  synthetic regression.

No push.
