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.
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.
Collapse CancelJobWithContext into CancelJob; eliminate 10 context.Background()
hits across the Job+Notification+Audit service cluster by threading ctx
through their handler-facing service interfaces.
Services (ctx-first):
- service/job.go: ListJobs, GetJob, CancelJob, ApproveJob, RejectJob now
accept ctx; the CancelJobWithContext wrapper is removed (handler callers
continue to invoke CancelJob, now ctx-aware).
- service/notification.go: ListNotifications, GetNotification, MarkAsRead
accept ctx.
- service/audit.go: ListAuditEvents, GetAuditEvent accept ctx.
Handlers (interface + callsites):
- handler/jobs.go, handler/notifications.go, handler/audit.go: local
service interfaces updated, r.Context() threaded at every callsite.
Tests:
- Mock services updated to match the new interfaces (ctx accepted and
ignored via '_ context.Context' first parameter; Fn closure fields
unchanged).
- job_test.go / notification_test.go callsites thread context.Background()
to match production shape.
Verification:
go build ./... ok
go vet ./... ok
go test -short ./... ok
go test -race -short ./... ok
golangci-lint run ./... 0 issues
Locked decisions from the M-2 plan:
D-1 ctx-only signatures (no dual forms)
D-4 preserve handler method names facing the router
D-5 domain types stay ctx-free

All 7 handler files now have test coverage: jobs (14 tests), notifications
(11), policies (15), issuers (15), targets (14). Negative-path integration
tests cover nonexistent resources, invalid payloads, malformed CSR, expired
cert lifecycle, and method-not-allowed errors. CI now enforces coverage
thresholds (service 60%+, handler 50%+) and includes connector tests.
