shankar0123 a41fc2d75c feat(ratelimit): Phase 13 Sprint 13.3 — wire backend selector + scheduler janitor + docs + helm (ARCH-M1 closure complete)
Phase 13 Sprint 13.3 — the completion half of the ARCH-M1
substantive close. Sprint 13.2 shipped the Postgres-backed
sliding-window limiter + multi-replica integration test; Sprint 13.3
wires the 6 call sites in cmd/server/main.go through the operator-
chosen backend selector, adds the rate_limit_buckets scheduler
janitor sweep, rewrites the observability doc, exposes the env-var
in the helm chart, and promotes the multi-replica integration test
to a required CI status check.

Signature ground-truth (sprint 13.2 + 13.3)
===========================================
Prompt-template signatures: `Allow(key string) error` and "5 call
sites." Actual repo: `Allow(key string, now time.Time) error` and 6
NewSlidingWindowLimiter call sites in cmd/server/main.go (the prompt
miscounted the second EST per-principal arm). Per CLAUDE.md "the repo
is truth," matched the live shape.

What changed
============

internal/config/server.go (+40 LOC):
  - Added `SlidingWindowBackend string` + `SlidingWindowJanitorInterval
    time.Duration` to RateLimitConfig with full operator-facing
    documentation of the two valid values (memory|postgres) +
    when-to-use-which decision tree.

internal/config/config.go (+27 LOC):
  - Load() reads CERTCTL_RATE_LIMIT_BACKEND (default "memory") +
    CERTCTL_RATE_LIMIT_JANITOR_INTERVAL (default 5m).
  - Validate() rejects anything other than ""/"memory"/"postgres"
    (empty = memory equivalence for test-built Configs that bypass
    Load()). Janitor interval must be ≥ 1 minute when set.
  - Failure modes return clear ::error:: with the env-var name + the
    valid values, so an operator typo ("postgress" → memory in a
    3-replica cluster) fails fast at startup.

internal/ratelimit/factory.go (NEW, 67 LOC):
  - NewLimiter(backend, db, maxN, window, mapCap) Limiter — single
    factory the 6 cmd/server/main.go call sites route through.
  - Drop-in signature: same maxN/window/mapCap as
    NewSlidingWindowLimiter (mapCap accepted + ignored for postgres
    — the rate_limit_buckets table grows until the janitor sweeps).
  - Defensive panic on unknown backend (config.Validate is SoT;
    this is belt-and-suspenders).

internal/ratelimit/postgres_gc.go (NEW, 73 LOC):
  - PostgresGC struct + NewPostgresGC + GarbageCollect.
  - Single-statement DELETE FROM rate_limit_buckets WHERE
    updated_at < NOW() - maxWindow. Idempotent.
  - maxWindow <= 0 is a no-op (operator opt-out).

internal/scheduler/scheduler.go (+90 LOC):
  - New RateLimitGarbageCollector interface (mirrors the
    ACMEGarbageCollector / SessionGarbageCollector contracts).
  - rateLimitGC field + rateLimitGCInterval + rateLimitGCRunning
    on Scheduler.
  - SetRateLimitGarbageCollector(gc) + SetRateLimitGCInterval(d)
    Setters following the existing acmeGC/sessionGC pattern.
  - rateLimitGCLoop() — JitteredTicker + atomic.Bool guard +
    per-tick context.WithTimeout(1m). Logs row count at Debug.
  - Loop counted in the Start() WaitGroup only when the GC is
    non-nil; cmd/server/main.go skips SetRateLimitGarbageCollector
    when backend=memory so the loop never launches for that case.

cmd/server/main.go (35 LOC diff):
  - All 6 ratelimit.NewSlidingWindowLimiter call sites now route
    through ratelimit.NewLimiter(cfg.RateLimit.SlidingWindowBackend,
    db, ...). Grep verification post-fix returns ZERO hits.
  - Six sites: breakglass loginLimiter (580), ocspLimiter (1003),
    exportLimiter (1068), EST failed-basic (1535), EST per-principal
    SCEP-mTLS arm (1591), EST per-principal SCEP arm (1613). The
    intune.NewPerDeviceRateLimiter site at line 1823 stays unmoved
    — its inner type-alias wrapper is the prompt's
    out-of-scope (cmd/server/*.go only).
  - Conditionally constructs PostgresGC + wires the scheduler janitor
    when backend=postgres; logs the wiring decision either way so
    operators see "rate-limit GC sweep enabled (postgres backend)"
    or "in-memory backend self-prunes" in the boot log.

internal/api/handler/{est,export,certificates,auth_breakglass}.go:
  - Replaced 5 *ratelimit.SlidingWindowLimiter field/Setter types
    with ratelimit.Limiter (the interface). Allow() satisfies the
    same call shape on both backends; the in-memory tests that
    construct *SlidingWindowLimiter still compile because the
    concrete type satisfies the interface (compile-time check in
    internal/ratelimit/limiter.go pins this).

docs/operator/observability.md (176 LOC diff):
  - Replaced the "per-process, in-memory, reset-on-restart, not
    shared across replicas" paragraph with the new
    configurable-backend section: operator decision tree,
    backend internals (memory vs postgres), janitor description,
    falsifiable closure proof (the Sprint 13.2 integration test
    name + invocation), helm chart wiring example.
  - Updated inventory to reflect the actual handler file paths +
    actual cap configurations (the prior doc said "60s window" for
    several limiters that actually use 60m / 24h windows).
  - Doc smoke confirmed: grep -c 'per-process, in-memory,
    reset-on-restart' docs/operator/observability.md = 0.

deploy/helm/certctl/values.yaml + templates/server-configmap.yaml +
templates/server-deployment.yaml:
  - Exposed server.rateLimiting.backend (default "memory") +
    server.rateLimiting.janitorInterval (default "5m") under the
    existing rateLimiting block.
  - ConfigMap renders both as rate-limit-backend +
    rate-limit-janitor-interval keys.
  - Deployment wires CERTCTL_RATE_LIMIT_BACKEND +
    CERTCTL_RATE_LIMIT_JANITOR_INTERVAL env vars from the configmap.
  - Helm render: `helm template deploy/helm/certctl --set
    server.rateLimiting.backend=postgres` shows the env-var on the
    server-deployment.yaml output.

.github/workflows/ci.yml (+12 LOC):
  - Added a new step in the Go Build & Test job that runs the
    Sprint 13.2 multi-replica integration test
    (TestRateLimit_PostgresBackend_CapEnforcedAcrossReplicas) with
    -tags=integration -race -timeout=300s. Fails the CI status check
    if the cross-replica row lock ever stops arbitrating across
    replicas — the ARCH-M1 closure regression gate.

Verification (all green locally; postgres integration via CI)

Selector contract verified — config.Validate() rejects any value
other than ""/memory/postgres at startup with a clear error message.

Sprint 13.4 next (ARCH-H1 OpenAPI authoring batch 1) is on a
different axis; ARCH-M1 closure is complete with this commit
modulo the Sprint 13.7 audit-HTML flip + zero-floor pin.

Closes: ARCH-M1 substantive remediation. The cross-replica rate-
limit-cap-enforcement gap that the audit recommended deferring to
v3 is closed; operators with server.replicas > 1 flip
CERTCTL_RATE_LIMIT_BACKEND=postgres and get exactly-cap enforcement
across the cluster (proved by the multi-replica integration test now
gating CI).

shankar0123 0e06f6c4fc 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 8b75e0311b 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 0729ee4 (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 db854ecc6f 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 ed19312df6 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 3d15a3e5af 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 dc1e0bfbaa 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.

shankar0123 0e29c416b1 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.

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 cdc9d03d5b fix(m-2): thread context through CertificateService cluster
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.

shankar0123 836534f2a7 feat: add issuer catalog page with type discovery + fix cert creation defaults (M33)
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

shankar0123 a8fc177118 fix: resolve NULL csr_pem scan errors and QA smoke test failures
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).

shankar0123 43a03c168c fix: Go 1.25 upgrade, codebase audit fixes, MCP server tests
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

shankar0123 28bef63569 fix: handle 'not found' errors as 404 in CRL/OCSP handlers
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.

shankar0123 762c523d59 feat: M15b — OCSP responder, DER CRL, short-lived exemption, revocation GUI
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).

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/
