shankar0123 8f2e5771db fix(middleware): SEC-006 — TTL-evict idle token-bucket rate-limiter entries
Sprint 2 unified-master-audit closure. Pre-fix the keyed rate
limiter's bucket map had no eviction. The package-level comment
explicitly noted the leak: high-cardinality unauthenticated traffic
(CGNAT churn, Tor exit lists, botnets, infinite-cardinality scanners)
grew process memory unboundedly. Production deploys with millions of
unique IPs would eventually OOM.

Fix:
  - RateLimitConfig.BucketTTL (env CERTCTL_RATE_LIMIT_BUCKET_TTL,
    default 1h, clamp-floor 1m). 1h chosen to be well above realistic
    operator IP churn windows (returning clients keep their bucket)
    and well below the unbounded-leak window the pre-fix code
    allowed.
  - tokenBucket gains a lastAccess field updated on every allow()
    call via touch(); reading via lastAccessTime() under the bucket's
    own mutex.
  - keyedRateLimiter.sweepLoop runs in a single goroutine per
    limiter (production wires 2: default + no-auth fallback), waking
    every BucketTTL/4. sweep() removes any bucket whose lastAccess
    is older than the cutoff and bumps evictedTotal atomically.
  - Both NewRateLimiter call sites in cmd/server/main.go (default
    stack and no-auth fallback) now thread cfg.RateLimit.BucketTTL.

Regression coverage:
  - TestKeyedRateLimiter_SweepEvictsIdleBuckets: 1000 synthetic IP
    keys populate the map, advance past TTL, call sweep() directly,
    assert map drained to 0 + evictedTotal=1000 + fresh key creates
    new bucket (map not poisoned).
  - TestKeyedRateLimiter_SweepKeepsActiveBuckets: inverse — a bucket
    touched within the TTL window survives the sweep. Catches a
    future regression that inverts the cutoff comparison.

Closes SEC-006.

shankar0123 21aeed4f4e legal: addlicense headers + normalize legacy variants (Phase 0 RED-4)
Phase 0 closure (Path B2, post-rewrite):

addlicense sweep — adds the canonical certctl LLC copyright + BUSL-1.1
SPDX header to every production Go file. Template:

  // Copyright 2026 certctl LLC. All rights reserved.
  // SPDX-License-Identifier: BUSL-1.1

Coverage: 338 / 338 production Go files (cmd/ + internal/, excluding
*_test.go and **/testdata/**). Pre-sweep coverage was 22 / 338 (6.5%);
post-sweep is 338 / 338 (100%).

Normalized 22 pre-existing legacy headers (`// Copyright (c) certctl`
+ `// SPDX-License-Identifier: BSL-1.1`) and 1 file using a
`Certctl Contributors` attribution. The legacy SPDX ID `BSL-1.1`
is non-standard; the official SPDX identifier for Business Source
License 1.1 is `BUSL-1.1` (capital U). All 338 files now share the
canonical form.

Generated via:
  addlicense -c "certctl LLC" -y 2026 \
    -f cowork/legal/copyright-header.tpl \
    -ignore '**/testdata/**' -ignore '**/*_test.go' \
    cmd/ internal/

Verification:
  find cmd internal -name '*.go' -not -name '*_test.go' \
    -not -path '*/testdata/*' \
    -exec grep -L '^// Copyright 2026 certctl LLC' {} \; | wc -l

  Returns: 0

gofmt clean. Header additions are comments only, no compile impact.

shankar0123 00eace8068 fix(api/cors): narrow Bundle-2 routes from wildcard to NewCORS(corsCfg)
Closes CRIT-3 of the 2026-05-10 audit. Bundle 2's OIDC handshake +
back-channel-logout + logout + bootstrap + breakglass-login routes were
wrapped by middleware.CORS — a hard-coded
Access-Control-Allow-Origin: * middleware that ignored the operator's
CERTCTL_CORS_ORIGINS knob (CWE-942). The properly-configured
middleware.NewCORS(corsCfg) exists right next to it but wasn't used here.
The deprecation comment on middleware.CORS said "Kept for health endpoints"
but Bundle 2 added four additional call sites without converting them.

This commit:

- Renames middleware.CORS -> middleware.CORSWildcard with a stronger doc
  block making the security tradeoff explicit at every remaining call
  site. The doc references the CI guard + the 2026-05-10 audit closure.

- Adds a CorsCfg middleware.CORSConfig field to router.HandlerRegistry
  and threads it from cmd/server/main.go using the existing
  cfg.CORS.AllowedOrigins value. The same config that drives the global
  corsMiddleware now also drives the per-route NewCORS wraps for the
  auth-exempt direct r.mux.Handle blocks.

- Swaps middleware.CORS -> middleware.NewCORS(reg.CorsCfg) for the 7
  credentialed auth-exempt routes:
    - GET  /auth/oidc/login
    - GET  /auth/oidc/callback
    - POST /auth/oidc/back-channel-logout
    - POST /auth/logout
    - POST /auth/breakglass/login
    - GET  /api/v1/auth/bootstrap
    - POST /api/v1/auth/bootstrap

- Keeps middleware.CORSWildcard for the 4 credential-free probe routes:
    - GET /health
    - GET /ready
    - GET /api/v1/version
    - GET /api/v1/auth/info

- Adds scripts/ci-guards/cors-wildcard-allowlist.sh — pins the 4-route
  allowlist; fails CI when a new middleware.CORSWildcard wrap appears
  outside the allowlist. Adding a new wildcard call site requires
  updating the allowlist AND documenting why in the commit body.

Operators who configured CERTCTL_CORS_ORIGINS=https://admin.example.com
expecting the OIDC + BCL + breakglass-login routes to honor it now do.
Previously those routes ignored the knob and emitted ACAO: * regardless.

Verification gate green:
- gofmt -l . clean
- go vet ./... clean
- go test -short -count=1 ./internal/api/... ./internal/auth/...
  ./internal/domain/auth/ ./internal/service/auth/ ./cmd/server/ pass

shankar0123 99a012e3be 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 0f81c1b956 ci: re-fix CodeQL #32 + repair loadtest f5-mock build context
Two unrelated CI failures from run #25305811340; fixed in one
commit since neither needs the other to land first.

CodeQL alert #32 (go/log-injection at middleware.go:68) reopened
after b0fc067. The previous fix introduced a scrubLogValue helper
backed by strings.NewReplacer; CodeQL's taint tracker only
recognizes the literal strings.ReplaceAll pattern as a sanitizer
(matches the OWASP example in the rule docs). Wrapper helpers and
NewReplacer don't trigger the recognition, so the analyzer kept
flagging.

Fix: drop the helper. Inline strings.ReplaceAll chains directly at
the call site for r.Method and r.URL.Path. Same runtime semantics
(strip CR/LF/NUL); CodeQL pattern-matches the literal call so the
alert can finally close.

Loadtest CI failure (run #25305811340 'k6 throughput run' job at
make loadtest):

  ERROR: failed to compute cache key: failed to calculate checksum
  of ref ...: "/deploy/test/f5-mock-icontrol": not found

The f5-mock-icontrol Dockerfile has `COPY deploy/test/f5-mock-icontrol/
./` which assumes the build context is the repo root. The
docker-compose.test.yml f5-mock-icontrol service correctly uses the
long-form build:

  build:
    context: ..        # = repo root from deploy/docker-compose.test.yml
    dockerfile: deploy/test/f5-mock-icontrol/Dockerfile

The loadtest compose at deploy/test/loadtest/docker-compose.yml
used the shorthand:

  build: ../f5-mock-icontrol

That sets context = the f5-mock-icontrol directory itself, breaking
the Dockerfile's COPY (it tries to find the directory inside itself).

Fix: change the loadtest compose to the long-form pattern matching
docker-compose.test.yml, with context: ../../.. (= repo root from
deploy/test/loadtest/) and explicit dockerfile path.

Verified locally:
  gofmt: clean.
  go vet ./internal/api/middleware/...: exit 0.
  go test -short -count=1 ./internal/api/middleware/...: ok 0.253s.
  python3 -c 'import yaml; yaml.safe_load(...)' on the compose
    file: parses clean.

    fully dropped).

shankar0123 b0fc067317 security: close CodeQL #17 (log injection) + #23 (SSRF false-positive reopen)
Two CodeQL alerts in one sweep — both medium-impact follow-ups
on already-merged guards.

Alert #17 — go/log-injection (CWE-117) at
internal/api/middleware/middleware.go:58:

  log.Printf("[%s] %s %s %d %v", requestID, r.Method, r.URL.Path, ...)

  r.Method and r.URL.Path are attacker-controllable (Go's net/http
  percent-decodes path segments before they reach handlers, so
  r.URL.Path can contain CR/LF in the decoded form even though raw
  HTTP request lines cannot). An attacker who controls a URL can
  forge new log entries by embedding %0A%0Afake-log-line.

  Fix: introduce scrubLogValue helper that replaces CR/LF/NUL with
  spaces. Apply to both r.Method and r.URL.Path. Replacement is
  structural (collapse to space) not destructive (drop) so an
  operator scanning the log still sees the field was present, just
  neutralized. Cheap fast path when the value contains no control
  chars (the common case).

  The deprecation comment on this function recommends NewLogging
  (slog with structured fields) where the logger escapes per-field
  natively. The Logging function is preserved for back-compat
  callers; the scrubber is the load-bearing CWE-117 defense for the
  legacy path.

Alert #23 — go/request-forgery (CWE-918) at scep_probe.go:271:

  CodeQL reopened the alert after commit e6919cd. The commit's
  in-function validator dispatch went through a function-pointer
  override hook:

    validateURL := s.scepValidateURL  // could be anything
    if validateURL == nil {
        validateURL = validation.ValidateSafeURL
    }
    if err := validateURL(rawURL); err != nil { ... }

  CodeQL's taint tracker doesn't trust the if-nil branch — the
  override field could be set to a permissive validator, and the
  analyzer can't prove the production validator runs.

  Fix: invert the dispatch. Always call validation.ValidateSafeURL
  literally first; only consult the test-override hook to grant an
  EXEMPTION when the production validator rejects:

    if err := validation.ValidateSafeURL(rawURL); err != nil {
        if s.scepValidateURL == nil || s.scepValidateURL(rawURL) != nil {
            return ... validate url error
        }
    }

  Same applies to ProbeSCEP's entry-point validator. Both call sites
  now have the literal validation.ValidateSafeURL call in-scope of
  the sink (client.Do), which CodeQL recognizes as a sanitizer.

  Production behavior is unchanged: scepValidateURL is nil in
  production, so the production validator's rejection is the only
  gate.

  Test ergonomics are preserved: scepValidateURL still grants the
  test-only exemption for httptest loopback URLs (only difference:
  the override now grants exemption from production validator's
  rejection rather than replacing the validator entirely; identical
  net effect).

Verified locally:
  gofmt: clean (strings is already imported in middleware.go).
  go vet ./internal/api/middleware/... + ./internal/service/...:
    exit 0.
  go test -short ./internal/api/middleware/...: ok 0.244s.
  go test -short ./internal/service/...: ok 4.965s
    (every existing scep_probe test still green — production +
    httptest paths both work).

shankar0123 7cb453a336 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 0f205a8) 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.

shankar0123 1b4de3fb2d Bundle E: Mechanical sweeps & defensive polish — 6 findings closed; L-004 deferred
Closes L-009 + L-010 + L-011 + L-013 + L-020 + L-021 from
comprehensive-audit-2026-04-25. L-004 deferred — recon found NO
rotation infrastructure exists at all; building it from scratch is
a feature project, not a Bundle-E mechanical sweep.

L-009 — ZeroSSL EAB URL configurable
  Audit's 'no timeout' claim was wrong: ari.go:329 has 15s timeout.
  internal/connector/issuer/acme/acme.go: zeroSSLEABEndpoint now
  lazily reads CERTCTL_ZEROSSL_EAB_URL from env at package init;
  defaults to ZeroSSL public endpoint. Pre-existing test override
  path preserved.

L-010 — Verified-already-clean
  grep -rn 'mock\.Anything' --include='*_test.go' . returned 0.
  certctl uses hand-rolled struct mocks (mockJobRepo, mockAuditRepo,
  etc.) with explicit method bodies; no testify-style mocks anywhere.

L-011 — IPv6 bracket-aware dialing pinned
  Every production net.Dial / DialTimeout site audited:
    cmd/agent/main.go:293 — intentional IPv4 literal '8.8.8.8:80'
    verify.go / tlsprobe / network_scan — net.Dialer (no string addr)
    email.go — net.JoinHostPort (bracket-aware)
    ssh.go — addr derives from JoinHostPort upstream
    ssrf.go — net.Dialer
  internal/connector/notifier/email/email_ipv6_test.go (NEW):
    TestJoinHostPort_IPv6BracketsRoundTrip pins IPv4/IPv6/zone variants;
    TestSMTPDialerUsesJoinHostPort source-greps email.go and fails CI
    if a future refactor swaps in 'host:port' concatenation.

L-013 — Verified-already-clean (monotonic-safe)
  Only one site uses now.Sub: middleware.go:393 in tokenBucket.allow().
  Both 'now' and tb.lastRefill come from time.Now() which carries
  monotonic-clock readings per Go's time package contract;
  intra-process now.Sub is monotonic-safe by construction. Doc
  comment block added above the call to make the invariant explicit.

L-020 (CWE-563) — ineffassign sweep, 8 unique sites
  certificate.go:135 — sortDir initial value dropped (set
    unconditionally below by SortDesc branch).
  certificate.go:169,175 — argCount post-increments dropped (var
    not read past the LIMIT/OFFSET formatting).
  agent_group.go, profile.go — page/perPage truly vestigial,
    replaced with _ = page; _ = perPage.
  issuer.go:633, owner.go:131, target.go:267, team.go:131 — same
    treatment for the audit-flagged second-function ListXxx clamps.
  First-function List() in issuer/owner/target/team KEEPS its
    clamp because page/perPage is used for in-memory slice
    pagination — ineffassign correctly didn't flag those.
  Build + tests green post-sweep.

L-021 — Transitive CVE bump
  go get golang.org/x/crypto@v0.45.0 golang.org/x/net@v0.47.0
    (crypto required net@0.47.0). go-text@v0.31.0 transitively
    bumped.
  Per tool-output govulncheck-verbose: x/net@v0.45.0 fixes
    GO-2026-4441 + GO-2026-4440; x/crypto@v0.45.0 fixes
    GO-2025-4134 + GO-2025-4135 + GO-2025-4116 — all 5 advisories
    cleared. Bundle B's ISV grep guard + Bundle D's release-time
    govulncheck step are the going-forward monitor + bump pass.

L-004 — Deferred to dedicated bundle
  Recon: zero hits for RotateAPIKey / rotated_at / key_status
    anywhere in source. API keys configured via
    CERTCTL_API_KEYS_NAMED env var; rotation is operator-managed
    (edit env + restart). Building rotation infrastructure from
    scratch is a feature project, not a mechanical sweep.

    - DecryptIfKeySet falls through v3 -> v2 -> v1 with AEAD verification
      at each step. Wrong-passphrase v3 reads cannot be silently

M-002 (CWE-862) — Auth-exempt allowlist constants + AST regression test
  Recon found auth-exempt surface spans TWO layers (audit's claim was
  incomplete):
    Layer 1 (router.go direct r.mux.Handle):
      GET /health, GET /ready, GET /api/v1/auth/info, GET /api/v1/version

  internal/api/router/auth_exempt_test.go (NEW, 2 tests):
    AST-walks router.go for every direct mux.Handle call and asserts
    set equals AuthExemptRouterRoutes; reads source bytes of Register /
    RegisterFunc and asserts they still wrap with middleware.Chain.
  cmd/server/auth_exempt_test.go (NEW, 2 tests):
    14-case table test on buildFinalHandler asserting documented
    prefixes route to noAuthHandler and authenticated routes route to
    apiHandler; inverse-overlap pin proves no documented bypass shadows
    an authenticated prefix.

M-013 (CWE-942) — CORS deny-by-default verified-already-clean + pin
  Audit claim 'default allows all origins if env-var unset' was WRONG.
  internal/api/middleware/middleware.go::NewCORS already denies cross-

  deploy/helm/certctl/values.yaml: new postgresql.tls.{mode,caSecretRef}
    operator-facing knobs. Default 'disable' preserves in-cluster pod-
    network behavior; PCI-scoped operators set verify-full.
  deploy/helm/certctl/templates/_helpers.tpl: certctl.databaseURL helper
    pipes postgresql.tls.mode into ?sslmode=.
  deploy/helm/certctl/templates/server-secret.yaml: uses the helper

startup log faithfully echoed 'authentication enabled type=jwt'.
Reasonable people read that and concluded JWT auth was on. It wasn't.
The auth-middleware wiring at cmd/server/main.go unconditionally routed
every request through the api-key bearer middleware regardless of
cfg.Auth.Type. So CERTCTL_AUTH_TYPE=jwt quietly compared the incoming
'Authorization: Bearer <token>' against whatever string the operator put
in CERTCTL_AUTH_SECRET — real JWT clients got 401, and operators who
treated CERTCTL_AUTH_SECRET as a *signing* secret (because they thought
they were configuring JWT) had effectively handed an attacker an api-key.
A security finding masquerading as a config option.

We chose the audit-recommended structural fix: remove the option, fail
fast at startup, and add the gateway-fronting pattern as the documented
forward path. Implementing JWT middleware would have meant jwks vs
static-secret rotation, claim mapping, expiry enforcement, audience and
issuer validation, key rollover semantics, and regression coverage at the
same depth as the existing api-key path — a feature, not a fix. Operators
who genuinely need JWT/OIDC front certctl with an authenticating gateway
(oauth2-proxy / Envoy ext_authz / Traefik ForwardAuth / Pomerium /
Authelia) and run the upstream certctl with CERTCTL_AUTH_TYPE=none. Same
shape works on docker-compose and Helm.

The change is comprehensive across 7 phases — every surface that
mentioned 'jwt' as a certctl-auth-type is updated, plus structural
backstops (typed enum, runtime guard, helm template validation, CI grep
guard) so the lie can't reappear.

Files changed:

Phase 1 — production code (typed enum + jwt removal):
- internal/config/config.go: AuthType typed alias + AuthTypeAPIKey /
  AuthTypeNone constants + ValidAuthTypes() helper. Validate() routes
  literal 'jwt' through a dedicated multi-line diagnostic naming the
  authenticating-gateway pattern, then cross-checks against
  ValidAuthTypes(). Secret-required branch simplified to api-key-only.
  Field comment on AuthConfig.Type rewritten to drop jwt and point at
  the gateway pattern.
- internal/api/middleware/middleware.go: AuthConfig.Type field comment
  references the typed config.AuthType constants.
- internal/api/handler/health.go: same treatment for HealthHandler.AuthType.
- cmd/server/main.go: defense-in-depth runtime switch immediately after
  config.Load() — exits 1 on any unsupported auth-type that bypassed the
  validator. Auth-disabled startup log explicitly names the
  authenticating-gateway pattern.

Phase 2 — tests (Red→Green, contract pinning):
- internal/config/config_test.go: TestValidate_JWTAuth_RejectedDedicated
  (two table rows pinning the dedicated G-1 error fires regardless of
  whether Secret is set), TestValidAuthTypesDoesNotContainJWT (property
  guard against future re-introduction),
  TestValidAuthTypesIsExactly_APIKey_None (allowed-set contract),
  TestValidate_GenericInvalidAuthType (pins non-jwt invalid values still
  hit the generic invalid-auth-type error). Removed the prior
  TestValidate_JWTAuth_MissingSecret happy-path since its premise is
  inverted post-G-1.
- internal/api/handler/health_test.go: removed
  TestAuthInfo_ReturnsAuthType_JWT (which baked the silent-downgrade lie
  into the regression suite). Pre-existing _APIKey test continues to
  cover the api-key happy path.

Phase 3 — spec, docs, env templates:
- api/openapi.yaml: auth_type enum dropped to [api-key, none] with
  inline comment naming the G-1 closure.
- .env.example (root): CERTCTL_AUTH_TYPE comment block rewritten to drop
  jwt and point at the gateway pattern; secret-required conditional
  simplified to api-key-only.
- docs/architecture.md: middleware-stack bullet rewritten to drop the
  JWT mention; new H3 'Authenticating-gateway pattern (JWT, OIDC, mTLS)'
  section explaining the design rationale and listing oauth2-proxy /
  Envoy ext_authz / Traefik ForwardAuth / Pomerium / Authelia / Caddy
  forward_auth / Apache mod_auth_openidc / nginx auth_request as the
  standard fronting options.
- docs/upgrade-to-v2-jwt-removal.md (new ~125 lines): migration guide
  with preconditions, what-changes, both recovery paths, complete
  docker-compose oauth2-proxy walkthrough, Traefik ForwardAuth and Envoy
  ext_authz patterns, rollback posture.

Phase 4 — Helm chart (template validation + docs):
- deploy/helm/certctl/templates/_helpers.tpl: new certctl.validateAuthType
  helper mirroring the existing certctl.tls.required pattern. Fails
  template render on any server.auth.type outside {api-key, none} with
  a multi-line diagnostic.
- deploy/helm/certctl/templates/server-deployment.yaml,
  server-configmap.yaml, server-secret.yaml: invoke the helper at the
  top of each template that depends on .Values.server.auth.type.
- deploy/helm/certctl/values.yaml: auth: block comment expanded with the
  G-1 rationale and gateway-pattern cross-reference.
- deploy/helm/CHART_SUMMARY.md: server.auth.type table row now surfaces
  the allowed set and points at the upgrade doc.
- deploy/helm/certctl/README.md: new 'JWT / OIDC via authenticating
  gateway' section with a Kubernetes-flavored oauth2-proxy + certctl
  walkthrough.

Phase 5 — release surface:
- CHANGELOG.md: new [unreleased] top entry with Breaking / Removed /
  Added / Changed sections; explicit pointer at
  docs/upgrade-to-v2-jwt-removal.md from the Breaking subsection.

Phase 6 — CI guardrail:
- .github/workflows/ci.yml: new 'Forbidden auth-type literal regression
  guard (G-1)' step. Scoped patterns catch the actual regression shapes
  (map literal, slice literal, switch case, OpenAPI enum, env-file
  default, AuthType('jwt') cast). Comments and the dedicated rejection
  branch are intentionally exempt; connector-package JWT references
  (Google OAuth2 / step-ca) are exempt as out-of-scope external
  protocols. Verified locally: the guard passes on the actual tree and
  fires on all 4 synthetic regression patterns.

Out of scope (explicitly untouched):
- internal/connector/discovery/gcpsm/gcpsm.go — Google OAuth2 service-
  account JWT (external protocol).
- internal/connector/issuer/googlecas/googlecas.go — same.
- internal/connector/issuer/stepca/stepca.go — step-ca's provisioner
  one-time-token JWT for /sign API.
- docs/test-env.md, docs/connectors.md, docs/features.md — describe
  external CAs' use of JWT, not certctl's auth shape.
- Implementing actual JWT middleware. Feature, not a fix.

Verification (all gates pass):
- go build ./... — clean
- go vet ./... — clean
- go test -short ./... — every package green
- go test -short -race ./internal/config/... ./internal/api/... — clean
- govulncheck ./... — no vulnerabilities in our code
- helm lint deploy/helm/certctl/ — clean
- helm template with auth.type=api-key — renders OK
- helm template with auth.type=none — renders OK
- helm template with auth.type=jwt — fails with validateAuthType
  diagnostic (exit 1)
- python3 yaml.safe_load on api/openapi.yaml — parses
- CI guardrail mirror — clean on real tree, fires on all 4 synthetic
  regression patterns
- Smoke test: 'CERTCTL_AUTH_TYPE=jwt ./certctl-server' exits non-zero
  with: 'Failed to load configuration: CERTCTL_AUTH_TYPE=jwt is no
  longer accepted (G-1 silent auth downgrade): no JWT middleware ships
  with certctl. To use JWT/OIDC, run an authenticating gateway
  (oauth2-proxy / Envoy ext_authz / Traefik ForwardAuth / Pomerium) in
  front of certctl and set CERTCTL_AUTH_TYPE=none on the upstream.
  See docs/architecture.md "Authenticating-gateway pattern" and
  docs/upgrade-to-v2-jwt-removal.md for the migration walkthrough'

shankar0123 ff7357f889 fix(lint): godoc comment on NewAuthWithNamedKeys must lead with function name (ST1020)
CI failure on master (commit 3287e17) — staticcheck ST1020:

  internal/api/middleware/middleware.go:125:1: ST1020: comment on exported
  function NewAuthWithNamedKeys should be of the form
  "NewAuthWithNamedKeys ..." (staticcheck)

When NewAuth was renamed to NewAuthWithNamedKeys during the M-002 auth
unification, the leading godoc sentence was left pointing at the old name.
Rewrite the comment so its first sentence starts with the new function
name, and expand the body to describe the named-key + admin-flag contract
introduced in 3287e17.

Also gitignore /.gopath/ — session-scoped tool install cache, same
category as /.gocache/ and /.gomodcache/.

Verification:
  go vet ./internal/api/middleware/...          — clean
  go build ./internal/api/middleware/...        — clean
  go test ./internal/api/middleware/...         — PASS (0.245s)
  staticcheck -checks=all,<project exclusions>  — clean across
    middleware, handler, service, domain, cmd/server, scheduler

Closes: CI failure on 3287e17.

shankar0123 3287e174dc Unify API auth + RFC-compliant CRL/OCSP (M-002 + M-003 + M-006, auto-closes M-001)
Closes the remaining P1 gaps from coverage-gap-audit.md (M-001/M-002/M-003/M-006)
on top of the C-001/C-002 ownership + agent-FK contract fixes landed in
a53a4b8. The work lands as a single commit spanning server, docs, tests,
and the React client.

M-002 — Named API keys with per-key actor propagation
  * Migration 000014 adds the 'api_keys' table (id, name, hash,
    principal, role, created_at, last_used_at, disabled_at) so every
    credential carries an identifiable principal instead of the
    opaque 'anonymous'/'api-key' sentinel.
  * Auth middleware now rotates through configured keys, performs
    constant-time hash comparison, stamps 'last_used_at', and emits
    an actor struct via contextWithActor(). The audit middleware,
    bulk-revocation handler, approval handlers, and MCP tool layer
    now read the principal off the context and persist it on every
    audit_events row.
  * Regression coverage:
      - internal/api/middleware/audit_test.go — actor propagation,
        principal redaction for disabled keys, anonymous fallback for
        unauthenticated endpoints.
      - internal/api/handler/bulk_revocation_handler_test.go,
        job_handler_test.go — principal-on-audit assertions.

M-003 — Authorization gates (Phase B)
  * Approval handler rejects self-approval / self-rejection with 403
    when the actor principal equals the job's requested_by field.
  * Bulk revocation is gated behind the 'admin' role; operators and
    viewers receive 403.
  * Regression coverage:
      - internal/service/job_test.go — TestApproveJob_NotSelf,
        TestRejectJob_NotSelf.
      - internal/api/handler/bulk_revocation_handler_test.go —
        TestBulkRevoke_RequiresAdmin, TestBulkRevoke_AdminSucceeds.

M-006 — RFC-compliant CRL/OCSP on the unauthenticated .well-known mux
  * Per RFC 8615, relying parties cannot reasonably be asked to
    authenticate against the issuing certctl instance to retrieve
    revocation material. CRL and OCSP move off the authenticated
    '/api/v1/crl*' and '/api/v1/ocsp/*' paths onto:
        GET /.well-known/pki/crl/{issuer_id}
            Content-Type: application/pkix-crl   (RFC 5280 §5)
        GET /.well-known/pki/ocsp/{issuer_id}/{serial}
            Content-Type: application/ocsp-response  (RFC 6960)
  * Non-standard JSON CRL shape is removed; only DER is served.
  * Short-lived certificate exemption (profile TTL < 1h → skip
    CRL/OCSP) is preserved; the response simply omits the serial.
  * Routes are registered on the unauthenticated 'finalHandler' mux
    in cmd/server/main.go alongside EST ('/.well-known/est/*') and
    SCEP ('/scep'). Legacy authenticated paths return 404.
  * Regression coverage:
      - internal/api/handler/certificate_handler_test.go — content
        type, DER parseability, 404 for unknown issuer.
      - internal/api/handler/adversarial_path_test.go — unauthenticated
        access asserted for CRL, OCSP, EST, SCEP.
      - internal/api/router/router_test.go — route-table assertion
        that '.well-known/pki/*', '.well-known/est/*', and '/scep' are
        mounted on the unauthenticated branch.

M-001 — Auto-closed by M-002
  EST and SCEP were already registered on the unauthenticated
  'finalHandler' mux; the router comment at
  internal/api/router/router.go:247 now matches reality. The
  adversarial-path tests above lock the behavior in.

Verification (all gates green):
  * go vet ./...                                           — clean
  * go build ./...                                         — ok
  * go test -short ./... (55+ packages)                    — all pass
  * web/ : npm test (225 Vitest tests)                     — all pass
  * web/ : npx tsc --noEmit                                — clean
  * grep sweep for '/api/v1/(crl|ocsp)' — 13 surviving hits,
    all intentional M-006 tombstone/relocation comments.

Documentation:
  * coverage-gap-audit.md — status flips M-001/M-002/M-003/M-006 →
    Fixed, with per-finding resolution paragraphs citing regression
    test IDs. (Audit file lives outside this repo; see cowork root.)
  * CLAUDE.md Project Status line updated with the auth-unification
    closure note.
  * docs/features.md, docs/architecture.md, docs/quickstart.md,
    docs/concepts.md, docs/connectors.md, docs/test-env.md,
    docs/testing-guide.md, docs/compliance-*.md, docs/demo-advanced.md
    — refreshed for the new '.well-known/pki/*' namespace and named
    API keys.
  * api/openapi.yaml — documents the new unauthenticated endpoints
    and removes the legacy '/api/v1/crl*' + '/api/v1/ocsp/*' paths.

.gitignore: adds '/.gocache/' and '/.gomodcache/' for the session-
scoped Go caches so they never enter the tree.

shankar0123 e3196e7b50 M-2 PR-F: Middleware/ACME ctx-propagation + contextcheck linter + audit closeout
Final PR in the six-commit M-2 sequence (PR-A: CertificateService cluster
cdc9d03, PR-B: IssuerService+TargetService eb14236, PR-C: Policy/Profile/
Owner/Team 2497be4, PR-D: Job/Notification/Audit ccd89c3, PR-E: AgentService
283ec27, PR-F: this commit). PR-A through PR-E collapsed the service-layer
shim methods and deleted every in-production context.Background() /
context.TODO() call from internal/service/; this PR completes the sweep
across the non-service tiers (HTTP middleware + ACME connector) and wires
the contextcheck linter so regressions fail CI.

Three narrow edits land the D-3 pattern (context.WithoutCancel for
subsidiary async writes and deferred shutdown contexts):

  - internal/api/middleware/audit.go  -- async audit goroutine now runs
    on auditCtx := context.WithoutCancel(r.Context()) instead of
    context.Background(). Preserves request-scoped values (trace ID, auth)
    while detaching from the request's cancellation so the audit write
    does not get killed when the response completes. Goroutine is still
    tracked via a.wg (M-1 shutdown drain) so Flush(ctx) behaviour is
    unchanged. CWE-770 Missing Release (goroutine leak potential) +
    CWE-400 Resource Exhaustion (missed cancellation propagation).

  - internal/api/middleware/middleware.go -- Recovery panic path now
    logs via slog.ErrorContext(ctx, ...) instead of log.Printf. Request-
    scoped trace/auth metadata now carries through the panic log, matching
    every other request log. D-3 non-bypass: the context is r.Context()
    captured before the defer, so even a panic mid-handler propagates
    the ctx's trace ID into the ERROR log line.

  - internal/connector/issuer/acme/acme.go (HTTP-01 challenge server
    shutdown) -- defer shutdown context derived from
    context.WithTimeout(context.WithoutCancel(ctx), 5s) instead of
    context.Background(). Preserves parent ctx values, detaches from
    parent cancellation so Shutdown always gets its full 5-second
    budget even when the parent was cancelled. Matches the same pattern
    applied in ACME's solveAuthorizationsDNS01 and solveAuthorizationsDNSPersist01.

Linter wiring: .golangci.yml adds `contextcheck` to the enabled set.
golangci-lint v2.11.4 now fails CI on any function that takes a
context.Context parameter but calls into context.Background() or
context.TODO() instead of propagating -- regression guard for all five
prior PRs.

Verification (CI parity, GOCACHE=/tmp/gocache GOMODCACHE=/tmp/gomodcache
GOLANGCI_LINT_CACHE=/tmp/lintcache):

  - go build ./... -> 0
  - go vet ./... -> 0
  - golangci-lint run (contextcheck enabled) -> 0 issues

  - rg "context\.(Background|TODO)\(\)" internal/service/ internal/scheduler/
    internal/connector/ internal/api/middleware/ -> 0 non-test hits
    (one pedagogical godoc reference in audit.go documenting why
    context.Background() would be wrong remains intentional)

Wire-format invariants preserved: 0 API routes, 0 SQL migrations, 0
frontend bytes, 0 OpenAPI bytes, 0 connector interface signature changes,
0 new env vars, 0 new external dependencies (pure context stdlib). The
AuditRecorder interface signature, the body-hash algorithm (SHA-256 16
hex chars), the excluded-path short-circuit, the actor-extraction path,
the responseWriter status-capture wrapper, the AuditServiceAdapter, and
all 116 API routes under /api/v1/, /.well-known/est/, /scep, /health,
/auth are byte-identical.
