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.
Collapses CertificateService, RevocationSvc, and CAOperationsSvc to
ctx-accepting method signatures. Removes context.Background() synthesis
at 24 internal call sites across certificate.go, revocation_svc.go, and
ca_operations.go.
- Primary repo calls inherit request cancellation via the passed ctx.
- Audit and notification dispatches use context.WithoutCancel(ctx) so
they survive client disconnect.
- Collapses TriggerRenewal/TriggerRenewalWithActor,
TriggerDeployment/TriggerDeploymentWithActor, and
RevokeCertificate/RevokeCertificateWithActor sibling pairs into single
canonical ctx-accepting methods (decisions D-1, D-2).
Handlers pass r.Context(). Mocks and tests updated to match new
signatures. No HTTP surface change, no OpenAPI change.
PR 1 of 6 in the M-2 remediation chain. Master green at this commit.

Issuer Catalog (M33):
- Shared issuer type config (issuerTypes.ts) with 6 supported + 2 coming-soon types
- Composable wizard components (TypeSelector, ConfigForm, ConfigDetailModal)
- Catalog card layout with Connected/Available/Coming Soon badges
- VaultPKI and DigiCert added to create wizard with full config fields
- ACME EAB fields (eab_kid, eab_hmac with sensitive flag)
- Issuer type filter dropdown on configured issuers table
- Config detail modal replacing 60-char truncation
- IssuerDetailPage uses shared typeLabels/redactConfig, Edit button, enabled/disabled status
- StatusBadge extended with Enabled/Disabled styles
- 2 new frontend tests (VaultPKI + DigiCert create payload verification)
Bug fixes:
- CertificateService.CreateCertificate now defaults Status to Pending and Tags to
empty map when not set (DB column DEFAULTs only apply when columns are omitted
from INSERT, but our repo always includes all columns)
- CreateCertificate handler now logs actual error via slog.Error before returning
generic 500, enabling root cause debugging

Root cause: certificate_versions.csr_pem is nullable in the schema but
Go code scanned it into a plain string. Used sql.NullString in
ListVersions and GetLatestVersion to handle NULL values correctly.
Also includes: partial update fetch-merge-update pattern to prevent FK
violations, nil directory guard in discovery service, diagnostic slog
logging in handlers, export handler 422 for unparseable PEM, OpenAPI
spec corrections, MCP tool description improvements, and test fixes.
Rewrites the Release Sign-Off section in testing-guide.md to individual
test-level granularity (320 rows) with smoke test results audited and
checked off (121 pass, 5 skip, 194 manual remaining).

Upgrade from Go 1.22 to 1.25 (minimum for MCP SDK, actively supported).
CI updated to match.
Codebase audit fixes:
- Local CA parseIP() now uses net.ParseIP — IP SANs no longer silently dropped
- Nil pointer guards in agent.go GetWorkWithTargets for target/cert enrichment
- MCP CreateCertificateInput marks owner_id/team_id as required
- NGINX connector uses CombinedOutput() — captures diagnostic output on failure
- Jobs handler validates JSON decode on rejection body — returns 400 on malformed
- CRL/OCSP handlers propagate requestID for error tracing
MCP server tests (26 tests):
- client_test.go: HTTP client coverage (GET/POST/PUT/DELETE, auth, 204, errors, binary)
- tools_test.go: tool registration, pagination, end-to-end flows with mock API

The error routing only checked for "issuer not found" but not
"certificate not found", causing cert-not-found errors to fall
through to a generic 500. Broadened the check to match any
"not found" error string for both CRL and OCSP handlers.

Backend:
- Embedded OCSP responder: GET /api/v1/ocsp/{issuer_id}/{serial} returns
signed OCSP responses (good/revoked/unknown) using CA key
- DER-encoded X.509 CRL: GET /api/v1/crl/{issuer_id} returns proper DER CRL
signed by issuing CA with 24h validity window
- Short-lived cert exemption: certs with profile TTL < 1 hour skip CRL/OCSP
(expiry is sufficient revocation for ephemeral workloads)
- Extended issuer connector interface with GenerateCRL and SignOCSPResponse
- Local CA implements full CRL/OCSP signing; ACME and step-ca return
appropriate "use native endpoint" errors
- IssuerConnectorAdapter bridges new methods between layers
Frontend:
- Revoke button on certificate detail page with RFC 5280 reason modal
- Revocation banner with reason display and timestamp
- Revocation status indicators in lifecycle section
- "Revoked" filter option in certificates list
- API client: revokeCertificate() function and Certificate type extensions
Tests: ~31 new tests across connector, service, handler, and adapter layers
Docs: milestones renumbered (M13-M14, M16-M18), M15b marked complete

Implements core revocation infrastructure: POST /api/v1/certificates/{id}/revoke
with all 8 RFC 5280 reason codes, JSON-formatted CRL at GET /api/v1/crl, webhook
and email revocation notifications, best-effort issuer notification, and immutable
revocation audit trail. Includes 48 new tests across service, handler, integration,
and domain layers (600+ total). Fixes 3 pre-existing test bugs (team_test error
matching, agent_group delete status code, team handler per_page validation).

Backend hardening:
- Fix 6 nginx.go non-constant format string build errors
- Add validation.go with hostname, PEM, and enum validators
- Apply input validation to all POST/PUT handlers (certificates,
agents, CSR, policies, teams, owners, targets, issuers)
- Fix unchecked JSON decode in TriggerDeployment handler
Frontend (Vite + React + TypeScript):
- Migrate from single-file SPA to proper build pipeline
- 7 pages: Dashboard, Certificates (list+detail), Agents, Jobs,
Notifications, Policies, Audit Trail
- TanStack Query for server state with auto-refetch intervals
- Certificate detail with version history and renewal trigger
- Job cancellation, status/type filtering, expiry countdowns
- Reusable components: DataTable, StatusBadge, ErrorState, PageHeader
- Dark theme with Tailwind CSS, sidebar nav via React Router
Server integration:
- Go server serves web/dist/ (Vite output) with SPA fallback
- Falls back to web/index.html for legacy mode
- .gitignore updated for web/node_modules/ and web/dist/
