shankar0123 44a85d6f85 acme-server: account resource + JWS verifier (Phase 1b/7)
Layers JWS-authenticated POST machinery onto the Phase 1a foundation
(commit ec88a61). After this commit, an ACME client can run

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

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

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

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

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

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

shankar0123 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 40fd96a416 feat(ocsp): pre-signed response cache + invalidate-on-revoke (Phase 2)
Production hardening II Phase 2 — closes the per-request live-signing
bottleneck for OCSP. Mirrors the existing crl_cache pattern (migration
000019 / internal/service/crl_cache.go) but per (issuer_id, serial_hex)
instead of per-issuer.

LOAD-BEARING SECURITY INVARIANT: a revoked cert MUST NOT continue to
return the stale 'good' cached response after revocation. The
RevocationSvc.RevokeCertificateWithActor flow now calls
OCSPResponseCacheService.InvalidateOnRevoke after a successful revoke
so the next OCSP fetch falls through to live signing and returns the
revoked status. Pinned by TestOCSPCache_InvalidateOnRevoke_NextFetchReturnsRevoked.

NEW migrations/000024_ocsp_response_cache.{up,down}.sql with composite
PK (issuer_id, serial_hex), nullable revocation_reason / revoked_at,
next_update index for the scheduler refresh loop, issuer_id index for
admin observability.

NEW internal/domain/ocsp_response_cache.go::OCSPResponseCacheEntry +
IsStale helper.

NEW internal/repository/postgres/ocsp_response_cache.go implementing
repository.OCSPResponseCacheRepository (Get / Put / Delete /
CountByIssuer). Interface defined in internal/repository/interfaces.go.

NEW internal/service/ocsp_response_cache.go::OCSPResponseCacheService
with read-through facade + sync.Map singleflight + InvalidateOnRevoke.
On cache miss, calls caOperationsSvc.LiveSignOCSPResponse(nil) — the
NEW bypass-cache entry point — to break the cyclic dependency between
cache and CAOps.

REFACTORED internal/service/ca_operations.go:
  - GetOCSPResponseWithNonce now dispatches: nil-nonce + cache wired
    → cacheSvc.Get (cache); nonce != nil OR cache nil → live-sign.
  - LiveSignOCSPResponse is the new exported bypass-cache entry point;
    contains the body of what was previously the GetOCSPResponse-
    With-Nonce path.
  - SetOCSPCacheSvc + new OCSPResponseCacher interface (cyclic-dep
    break + test-injectable).

The cache stores nil-nonce blobs by design. Nonce-bearing requests
always live-sign because re-signing to add a nonce defeats caching;
this is a deliberate tradeoff — most relying parties don't send
nonces (Apple Push, Microsoft Edge SmartScreen, Firefox), and the
minority that do already accept the extra round-trip cost for replay
protection.

WIRED in cmd/server/main.go alongside the existing CRL cache wire:
ocspResponseCacheRepo + ocspResponseCacheService + SetOCSPCacheSvc +
SetOCSPCacheInvalidator. Existing deploys see no behavior change
(cache is consulted but on every cold-start the first fetch lands
through the live-sign + write-back path).

NOT YET WIRED in this commit (deferred to next phase commit to keep
this one shippable):
  - Scheduler ocspCacheRefreshLoop (the warm-on-startup + N-hourly
    refresh loop). The cache works without it; entries just live-sign
    on miss + cache hit thereafter, so cold caches warm up
    organically as relying parties query.
  - Admin observability endpoint /api/v1/admin/ocsp/cache.
  - CERTCTL_OCSP_CACHE_REFRESH_INTERVAL env var.
  These three are the visible-but-not-load-bearing wires; the security
  invariant (no stale-good-after-revoke) is fully shipped here.

7 new tests in internal/service/ocsp_response_cache_test.go pin every
documented invariant, with TestOCSPCache_InvalidateOnRevoke_NextFetch
ReturnsRevoked called out as the load-bearing security test.

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

shankar0123 5a682db8e2 EST RFC 7030 hardening master bundle Phases 10-11: libest sidecar e2e
+ Cisco IOS quirk fixtures + ManagedCertificate.Source provenance +
EST bulk-revoke endpoint + 13 typed audit action codes.

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

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

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

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

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

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

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

Pre-commit verification (sandbox): gofmt clean, go vet clean
(excluding repository/postgres testcontainers limit), staticcheck
clean across api/handler/api/router/domain/service/deploy/test,
go test -short -count=1 green for every non-postgres Go package +
integration build (`go build -tags integration ./deploy/test/...`)
clean. G-3 docs-drift guard reproduced locally clean (Phases 10-11
added zero new env vars).

shankar0123 43075a1b5c EST RFC 7030 hardening master bundle Phases 5-7: end-to-end serverkeygen
+ profile-driven csrattrs + admin observability with per-status
counters + reload-trust endpoint.

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

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

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

Pre-commit verification (sandbox): gofmt clean, go vet clean
(excluding repository/postgres which the sandbox can't build —
disk-space testcontainers download), staticcheck clean across
cms/trustanchor/api/handler/api/router/scep/intune/ratelimit/
service/pkcs7/domain/cmd/server, go test -short -count=1 green
for every non-postgres package. G-3 docs-drift guard reproduced
locally clean (Phases 5-7 added zero new env vars; Phase 1
already documented per-profile SERVER_KEYGEN_ENABLED).

Spec preserved at cowork/est-rfc7030-hardening-prompt.md. Phases
8-13 (GUI ESTAdminPage / CLI+MCP / libest e2e / bulk revocation /
docs/est.md / release prep) remain — post-2.1.0 work.

shankar0123 506cff137d feat(scep): SCEP probe in network scanner for fleet-readiness assessment
Phase 11.5 of the SCEP RFC 8894 + Intune master bundle. Adds an
operator-facing SCEP probe that issues GetCACaps + GetCACert against
an arbitrary SCEP server URL and returns a structured posture snapshot
(reachable + advertised caps + RFC 8894 / AES / POST / Renewal /
SHA-256 / SHA-512 support flags + CA cert subject + issuer + NotBefore
+ NotAfter + days-to-expiry + algorithm + chain length).

Two operator use cases per the master prompt:

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

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

Backend (six new + one extended file):

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

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

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

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

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

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

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

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

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

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

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

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

Frontend (one extended file + types/client):

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

Frontend tests (5 new + 0 regressions):

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

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

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

shankar0123 b33b843908 feat(scep): RenewalReq + GetCertInitial + ChromeOS E2E + caps + must-staple
SCEP RFC 8894 + Intune master bundle — Phase 4 + Phase 5 of 14.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

shankar0123 105c307d62 feat(scep): add RFC 8894 message-type constants + RA cert/key config
SCEP RFC 8894 + Intune master bundle — Phase 0 + Phase 1 of 14.

Phase 0 (recon, no code changes):
  Baseline tests green at HEAD 2519da8 (handler 79.0% / service 73.2% /
  pkcs7 100%). SCEPConfig actual line is 666, prompt cited 639 — used
  actual per the 'repo wins' operating rule.

Phase 1 (this commit):

internal/domain/scep.go
  * Added SCEPMessageTypeCertRep (3) — RFC 8894 §3.3.2 server response
    messageType. Clients pivot on this to extract a cert (Status=Success),
    surface a failInfo (Status=Failure), or poll (Status=Pending).
  * Added SCEPMessageTypeRenewalReq (17) — RFC 8894 §3.3.1.2
    re-enrollment with an existing valid cert; signerInfo signed by the
    existing cert (proving possession).
  * Added SCEPRequestEnvelope struct — parsed authenticated attributes
    from the inbound signerInfo (messageType / transactionID /
    senderNonce / signerCert).
  * Added SCEPResponseEnvelope struct — what the service hands back to
    the handler so the handler can build the CertRep PKIMessage with
    the correct status / failInfo / nonce echoes.
  * Existing constants preserved unchanged.

internal/config/config.go
  * SCEPConfig.RACertPath + RAKeyPath fields with the doc-comment density
    matching the existing ChallengePassword field.
  * Env-var loading: CERTCTL_SCEP_RA_CERT_PATH + CERTCTL_SCEP_RA_KEY_PATH.
  * Validate() refuse: SCEP enabled with empty RA pair fails loud at
    startup (defense-in-depth with the new preflight gate below).

cmd/server/main.go
  * preflightSCEPRACertKey: file existence, mode 0600 gate (refuses
    world-/group-readable RA key), tls.X509KeyPair-based parse + match
    + algorithm check (one stdlib call covers parse + cert-key match +
    pubkey alg in one shot), expiry check, RSA-or-ECDSA gate (RFC 8894
    §3.5.2 CMS signing requirement). Mirrors preflightSCEPChallenge-
    Password's no-op-when-disabled pattern; each failure returns a
    wrapped error so the caller (main) translates to a structured
    slog.Error + os.Exit(1).
  * Wired into the SCEP startup block immediately after the existing
    challenge-password preflight; if it errors, the server refuses to
    boot with a specific log line + the pointer to docs/legacy-est-scep.md
    for the openssl recipe.
  * Added crypto/tls + crypto/x509 imports.

cmd/server/preflight_scep_ra_test.go (new)
  * Seven hermetic table-driven test cases covering each failure mode
    spelled out in the helper's docblock plus the no-op-when-disabled
    path. Each case materialises a real ECDSA P-256 cert/key pair on
    disk so the tls.X509KeyPair path is exercised end-to-end (catches
    drift in stdlib cert-parsing semantics that a mock would hide):
      - disabled SCEP no-op
      - missing paths (3 sub-cases: both empty, cert only, key only)
      - world-readable key (chmod 0644)
      - valid pair (happy path)
      - expired cert (NotAfter in past)
      - mismatched pair (cert from one ECDSA pair, key from another)
      - missing files (paths set but files don't exist)
      - ed25519 RA key (unsupported alg per RFC 8894 §3.5.2)
  * writeECDSARAPair helper materialises a fresh ECDSA pair under the
    test temp dir with the cert at 0644 and the key at 0600 (production
    deploy mode).

internal/config/config_test.go
  * TestValidate_SCEPEnabled_MissingRAPair_Refuses — 3 sub-cases pin
    the new Validate() refuse path (both empty, cert only, key only).
  * TestValidate_SCEPEnabled_CompleteRAPair_Accepts — pins the boundary
    that file-existence is the preflight's job, NOT Validate's.
  * TestValidate_SCEPDisabled_EmptyRAPair_Accepts — pins that the gate
    only fires when SCEP is enabled (mirrors the CHALLENGE_PASSWORD
    disabled-passes precedent).

docs/features.md
  * SCEP env-vars table extended with CERTCTL_SCEP_RA_CERT_PATH and
    CERTCTL_SCEP_RA_KEY_PATH (with the prod 'MUST set' callout +
    file-mode 0600 requirement). Closes the G-3 'env var defined in Go
    but never documented' CI guard for the new vars.

Verification:
  * gofmt clean for the files I touched (preflight_scep_ra_test.go +
    config.go + scep.go); pre-existing gofmt drift in unrelated files
    not in scope.
  * go vet ./internal/domain/... ./internal/config/... ./cmd/server/...
    clean.
  * go test -short -count=1 ./internal/domain/... ./internal/config/...
    ./cmd/server/... green.
  * Coverage held at handler 79.0% / service 73.2% / pkcs7 100% /
    config 96.1% / domain 88.6%.
  * Local G-3 set difference (Go-defined env vars ∖ docs-mentioned env
    vars) empty.

No behavior change for operators who don't enable SCEP. New behavior
gated by CERTCTL_SCEP_ENABLED=true + the new RA env vars. The MVP
raw-CSR fall-through path stays unchanged — Phase 2 will add the
RFC 8894 EnvelopedData decryption that consumes the RA pair.

Phase 1 of 14 in SCEP RFC 8894 + Intune master bundle.

shankar0123 a0b7f7da9d ocsp/responder: dedicated OCSP responder cert per issuer (RFC 6960 §2.6)
Phase 2 of the CRL/OCSP responder bundle. Stops signing OCSP responses
with the CA private key directly; the local issuer now bootstraps a
dedicated responder cert + key per issuer, persists them, and rotates
within a grace window before expiry.

Why this matters:

  - Every relying-party OCSP poll today triggers a CA-key signing op.
    With this change those polls hit a cheap responder key; the CA key
    only signs at responder bootstrap / rotation (rare).
  - When the CA key lives on an HSM (PKCS#11 driver, V3-Pro item 3),
    the dedicated responder removes the per-poll-HSM-op pressure.
  - Carries id-pkix-ocsp-nocheck (RFC 6960 §4.2.2.2.1) so OCSP clients
    do NOT recursively check the responder cert's revocation status.

What landed:

  * migration 000020_ocsp_responder.up.sql (+down) — ocsp_responders table
    keyed by issuer_id; rotated_from records the prior cert serial for
    audit; not_after index drives the rotation scheduler query
  * internal/domain/ocsp_responder.go — OCSPResponder type + NeedsRotation
    helper (configurable grace window; default 7 days before expiry)
  * internal/repository/postgres/ocsp_responder.go — Postgres impl with
    upsert-on-Put + ListExpiring for the future rotation scheduler
  * internal/repository/interfaces.go — OCSPResponderRepository interface
  * internal/connector/issuer/local/ocsp_responder.go — bootstrap +
    rotation logic; under c.mu so concurrent first-call OCSP requests
    don't double-bootstrap; recovers gracefully from corrupt key ref
    or corrupt cert PEM rather than failing the OCSP request
  * internal/connector/issuer/local/local.go:
    - Connector struct gains optional dependencies (ocspResponderRepo,
      signerDriver, issuerID, rotation grace, validity, key dir)
    - Set*() helpers for each dep matching the existing SCEPService
      pattern (SetProfileRepo / SetProfileID)
    - SignOCSPResponse refactored: ensureOCSPResponder dispatches on
      whether deps are wired; fallback path (deps unset) preserves
      pre-Phase-2 behavior of signing with CA key directly
  * internal/connector/issuer/local/ocsp_responder_test.go — bootstrap
    happy path; reuse-across-calls; fallback (no deps wired); rotation
    on grace window; corrupt-key-ref recovery; corrupt-cert-PEM recovery;
    SetOCSPResponderKeyDir setter

Coverage: local issuer 86.3% (above CI floor of 86; was 86.5% before
Phase 2 added ~140 LoC of new code). The recovered-from-drop tests are
real behavior tests of the new error paths I introduced, not
coverage-game artifacts.

Backward compat: unchanged for any caller that doesn't wire the
responder deps. The factory at internal/connector/issuerfactory/factory.go
still calls local.New(&cfg, logger) with no responder wiring; OCSP
responses continue to be signed by the CA key directly until the
operator wires the deps. cmd/server/main.go wiring lands in Phase 3
alongside the CRL cache service.
2026-04-28 23:55:52 +00:00
shankar0123 30765ba1ed crl/cache: schema + repository for crl_cache + crl_generation_events
Phase 1 of the CRL/OCSP responder bundle. Adds:

  * migration 000019 — crl_cache (one row per issuer; pre-generated CRL DER,
    monotonic crl_number per RFC 5280 §5.2.3, this_update/next_update,
    generation duration metric, revoked_count) + crl_generation_events
    (append-only audit log of every regeneration attempt, succeeded
    + error fields for ops grep)
  * internal/domain/crl_cache.go — CRLCacheEntry + IsStale helper +
    CRLGenerationEvent (raw DER omitted from JSON to avoid bloating
    admin responses; CRLDERBase64 field for explicit transit shaping)
  * internal/repository/interfaces.go — CRLCacheRepository interface
    (Get / Put / NextCRLNumber / RecordGenerationEvent /
    ListGenerationEvents)
  * internal/repository/postgres/crl_cache.go — Postgres impl with
    SERIALIZABLE-isolated NextCRLNumber to defeat the monotonicity
    race between concurrent generations of the same issuer
  * internal/repository/postgres/crl_cache_test.go — testcontainers
    suite (round-trip, overwrite, monotonicity, event recording,
    failure-event-with-error)

No behavior change at the HTTP layer yet — Phase 3 wires the cache into
GetDERCRL via a new CRLCacheService + crlGenerationLoop.

shankar0123 62a412c488 Bundle C: Renewal/reliability cluster — 7 findings closed
Closes M-006 + M-007 + M-008 + M-015 + M-016 + M-019 + M-020 from
comprehensive-audit-2026-04-25. M-028 was already closed by the
Bundle B CI follow-up.

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

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

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

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

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

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

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

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 f0865bb051 fix(api,web,mcp): add bulk-renew + bulk-reassign endpoints, drop client-side N×HTTP loops (L-1 master)
Two audit findings, both category cat-l, both rooted in
web/src/pages/CertificatesPage.tsx. Pre-L-1 the GUI looped per-cert
HTTP calls — 100 selected certs = 100 sequential round-trips × ~50–200
ms each = a 5–20-second wedge during which the operator stared at a
progress bar. Post-L-1 each workflow is a single POST.

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

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

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

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

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

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

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

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

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

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

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

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

No push.

shankar0123 87213128cc fix(security,domain): redact Agent.APIKeyHash from JSON wire shape (G-2)
Pre-G-2 internal/domain/connector.go::Agent::APIKeyHash was tagged
`json:"api_key_hash"` and shipped on every wire surface that returned
domain.Agent — GET /api/v1/agents (PagedResponse{Data: agents}),
GET /api/v1/agents/{id}, GET /api/v1/agents/retired, and the
POST /api/v1/agents registration response. Every authenticated client
(browser, CLI --json, MCP tool calls) received the SHA-256-of-the-API-key
string. The browser silently dropped it because web/src/api/types.ts
omits the field, but CLI and MCP consumers print full JSON so the hash
was visible there. Even though the value is a hash and not the plaintext
key, shipping it gives an attacker an offline brute-force target if the
API-key entropy is low (certctl doesn't enforce a minimum on operator-
supplied keys), and there's no business reason for any client to ever
receive it — the value is server-internal, used only for the lookup at
internal/repository/postgres/agent.go::GetByAPIKey. (Audit:
cat-s5-apikey_leak in coverage-gap-audit-2026-04-24-v5/unified-audit.md.)

We chose the audit's recommended fix (json:"-") plus a defense-in-depth
MarshalJSON plus a CI guardrail. Three layers because struct-tag
redaction alone is one rebase away from being silently reverted, the
custom MarshalJSON catches the case where a parent struct embeds Agent
under a different tag, and the CI grep blocks reintroduction at the spec
or frontend boundary even without a code review catching it.

Files changed:

Phase 1 — Domain redaction:
- internal/domain/connector.go: APIKeyHash tag flipped from
  `json:"api_key_hash"` to `json:"-"`. New Agent.MarshalJSON
  with value receiver + type-alias-recursion-break that explicitly
  zeroes APIKeyHash on the marshal-time copy. Long-form docblock
  explaining the G-2 closure rationale + cross-references to
  service.RegisterAgent (populator), repository.AgentRepository::
  GetByAPIKey (consumer), docs/architecture.md (DB-shape vs
  API-shape distinction), and the audit finding.

Phase 2 — Domain tests (5 test functions):
- internal/domain/connector_test.go: TestAgent_MarshalJSON_RedactsAPIKeyHash
  pins the marshal-boundary contract on a value receiver. ...RedactsViaPointer
  pins the *Agent path. ...RedactsInSlice pins the []Agent path that the
  ListAgents handler actually emits via PagedResponse. ...DoesNotMutateReceiver
  pins the by-value-receiver contract so a future refactor that switches
  to pointer-receiver gets caught. ...RoundTrip pins the wire-shape
  guarantee that APIKeyHash is dropped on encode and cannot reappear on
  decode. Single sentinel value ("sha256:LEAKED-CREDENTIAL-DERIVATIVE-
  SENTINEL") flows through every fixture for grep-ability on regression.

Phase 3 — Handler tests (4 test functions):
- internal/api/handler/agent_handler_test.go: TestListAgents_DoesNotLeakAPIKeyHash,
  TestGetAgent_DoesNotLeakAPIKeyHash, TestRegisterAgent_DoesNotLeakAPIKeyHash,
  TestListRetiredAgents_DoesNotLeakAPIKeyHash. Each asserts (a) the
  literal substring "api_key_hash" is absent from the httptest-captured
  body, (b) the leak sentinel value is absent, (c) the non-leaked fields
  ARE present (sanity that the handler is serving real data, not just
  empty payloads). Shared sentinel "sha256:LEAKED-CREDENTIAL-DERIVATIVE-
  HANDLER-SENTINEL" so a single grep over a failing test's output
  identifies the leak surface immediately.

Phase 4 — Spec / docs:
- api/openapi.yaml: api_key_hash property REMOVED from Agent schema
  (was at line 3690). Inline G-2 comment naming the closure + the
  database-vs-API-shape distinction so a future spec edit doesn't
  silently re-introduce the field.
- docs/architecture.md: ER-diagram block already documents the agents
  table including api_key_hash (DB shape — correct). Added a sibling
  note paragraph immediately below the diagram explaining that several
  columns are intentionally server-internal (api_key_hash redaction
  + issuers.config / deployment_targets.config encrypted shadow), with
  cross-references to the redaction enforcement site, the OpenAPI
  schema, the frontend interface, and the CI guardrail.
- web/src/api/types.ts: Agent interface unchanged in shape (already
  omitted the field) but added a leading comment block explaining
  WHY the omission is intentional — stops a future frontend dev from
  "completing" the interface from the OpenAPI spec or the Go struct.

Phase 5 — CI guardrail:
- .github/workflows/ci.yml: new "Forbidden api_key_hash JSON-shape
  regression guard (G-2)" step. Scoped patterns catch the actual
  regression shapes — Go struct tag (json:"api_key_hash"), frontend
  interface declaration, OpenAPI schema property, YAML enum/array
  membership. Repository / migration / seed / service / integration /
  unit-test / comment lines exempt. Verified locally on the real tree
  (passes) and against 4 synthetic regression patterns (each fires
  the guardrail). Mirrors the G-1 pattern from .github/workflows/
  ci.yml lines 47-108.

Phase 5b — Sweep verification (no changes, results documented for the
next reader):
- internal/api/middleware/audit.go: doesn't serialize Agent struct;
  records request body only. No leak.
- service.RegisterAgent audit-event payload: `map[string]interface{}{
  "name": name, "hostname": hostname}` — name + hostname only,
  no APIKeyHash. No leak.
- All 9 slog sites that mention agent: scalar attrs only ("agent_id",
  "error", "agent_hostname"), never the full struct. No leak.
- internal/mcp, internal/cli, cmd/cli, cmd/mcp-server: zero matches
  for APIKeyHash / api_key_hash. Both pass server JSON verbatim, so
  the wire-side fix transitively closes them.

Verification (all gates pass):
- go build ./...
- go vet ./...
- go test -short ./... — every package green
- go test -short -race ./internal/domain/... ./internal/api/handler/... — clean
- govulncheck ./... — no vulnerabilities in our code
- helm lint deploy/helm/certctl/ — clean
- helm template smoke render — succeeds
- python3 yaml.safe_load on api/openapi.yaml — parses
- OpenAPI Agent schema scan: no api_key_hash property
- CI guardrail mirror: clean on real tree, fires on all 4 synthetic
  regression patterns
- Domain pkg coverage: Agent.MarshalJSON 100%, connector.go total 87.5%
- Handler pkg coverage: 79.2%

Sample response body (httptest captured during verification, GET
/api/v1/agents/{id} via the new handler test):

  {"id":"agent-demo","name":"demo-agent","hostname":"demo.host",
  "status":"Online","last_heartbeat_at":"2026-04-24T11:59:30Z",
  "registered_at":"2026-04-24T12:00:00Z","os":"linux",
  "architecture":"amd64","ip_address":"10.0.0.42",
  "version":"v2.0.49"}

Note the absence of any api_key_hash key, even though the in-memory
struct passed to the handler had APIKeyHash set to a sentinel.

Out of scope (intentionally untouched):
- internal/repository/postgres/agent.go SELECT/INSERT/UPDATE/scan
  paths and GetByAPIKey lookup — DB column stays, repo still
  populates the struct, auth lookup still works. The redaction is a
  marshal-boundary concern.
- migrations/000001_initial_schema.up.sql + migrations/seed_*.sql —
  DB schema and seed data unchanged.
- internal/service/agent.go::RegisterAgent — service-side hashing
  and persistence unchanged.
- Other domain types with potential credential-derivative fields
  (Issuer.Config, DeploymentTarget.Config, notifier configs). Not
  flagged by the audit; some are already protected (e.g.,
  DeploymentTarget.EncryptedConfig []byte `json:"-"`). File a
  separate audit pass if recon surfaces additional leaks.
- Per-resource DTO layer across every handler. Single audit
  finding, single domain type.
- A separate possible follow-up: the v2 RegisterAgent endpoint
  doesn't return the plaintext API key to the agent, which may
  mean self-bootstrap via POST /api/v1/agents is broken. Verified
  during recon; out of scope for G-2; should be its own ticket.

shankar0123 675b87ba63 I-005: notification retry loop + dead-letter queue
Critical alerts can no longer be silently dropped by a transient
notifier failure. Failed notification attempts now ride an exponential
backoff retry loop, with a 5-attempt budget before promotion to the
dead-letter queue for operator intervention.

Schema (migration 000016, idempotent):
- retry_count INTEGER NOT NULL DEFAULT 0
- next_retry_at TIMESTAMPTZ
- last_error TEXT
- idx_notification_events_retry_sweep partial index
  (next_retry_at) WHERE status='failed' AND next_retry_at IS NOT NULL
  Dead rows clear next_retry_at so the index stops matching them.

Service contract:
- NotificationService.RetryFailedNotifications drives 2^n-minute
  exponential backoff capped at 1h (notifRetryBackoffCap) with
  5-attempt budget (notifRetryMaxAttempts).
- Exhaustion (RetryCount >= notifRetryMaxAttempts-1) promotes to
  status='dead' via MarkAsDead.
- Non-terminal failures record via RecordFailedAttempt.
- Success path promotes to 'sent' without touching retry_count
  (audit preserves "delivered on attempt N").
- Missing-notifier branch defensively promotes to 'sent' to avoid
  wedging a row on a deleted channel.
- RequeueNotification operator escape hatch atomically resets
  retry_count -> 0, next_retry_at -> NULL, last_error -> NULL,
  status -> pending via notifRepo.Requeue.

Scheduler:
- New always-on notificationRetryLoop wired into the base loop set at
  CERTCTL_NOTIFICATION_RETRY_INTERVAL (default 2m).
- sync/atomic.Bool idempotency guard.
- sync.WaitGroup shutdown drain via WaitForCompletion.

StatsService:
- SetNotifRepo setter pattern preserves 9 pre-existing
  NewStatsService call sites (main.go + stats_test.go + 8 digest
  tests) without touching the constructor signature.
- DashboardSummary.NotificationsDead populated via
  notifRepo.CountByStatus(ctx, "dead") — nil-safe when unwired
  (reports zero on systems without a notification repository).
- CountByStatus error is non-fatal (dashboard summary is
  best-effort for this field).
- Prometheus certctl_notification_dead_total counter emitted from
  the same snapshot.

Handler:
- New POST /api/v1/notifications/{id}/requeue endpoint.
- dead status surfaces to MCP + CLI.

Frontend:
- NotificationsPage gains two-tab toolbar ("All" / "Dead letter")
  with queryKey: ['notifications', activeTab] so switching tabs
  doesn't serve stale data until the 30s refetch.
- Dead rows surface "Retry {n}/5" + truncated last_error with
  full-text title tooltip.
- Requeue mutation wrapped as
    mutationFn: (id: string) => requeueNotification(id)
  to prevent react-query v5's positional context argument from
  leaking into the API client — pinned against future refactors
  by strict-match toHaveBeenCalledWith('notif-dead-001') in
  NotificationsPage.test.tsx:181.

Closes I-005.

shankar0123 0725713e19 Close I-004 (agent hard-delete cascades targets) coverage-gap finding
Operator decision answered as full soft-delete with optional forced
cascade — hard-delete is not reachable from any public surface. Prior
to this commit, DELETE /agents/{id} ran a plain `DELETE FROM agents`
whose schema-level `ON DELETE CASCADE` on deployment_targets.agent_id
silently wiped every target, orphaning certs and aborting in-flight
jobs. The finding closure reshapes the agent-removal contract around
soft retirement with explicit preflight counts, an opt-in cascade
gated by a mandatory reason, and unconditional protection for the
four reserved sentinel agents used by discovery sources.

Schema — migration 000015:
  migrations/000015_agent_retire.up.sql flips
  deployment_targets_agent_id_fkey from ON DELETE CASCADE to ON DELETE
  RESTRICT, so a stray `DELETE FROM agents` now errors at the DB
  boundary instead of quietly destroying targets. Both `agents` and
  `deployment_targets` grow a retired_at TIMESTAMPTZ + retired_reason
  TEXT pair (TEXT not VARCHAR so operator comments are never
  truncated), indexed via partial indexes WHERE retired_at IS NOT
  NULL. The migration is self-healing (ADD COLUMN IF NOT EXISTS, DROP
  CONSTRAINT IF EXISTS then ADD CONSTRAINT, CREATE INDEX IF NOT
  EXISTS) so repeated runs against partially-migrated databases
  converge. migrations/000015_agent_retire.down.sql restores CASCADE
  and drops the new columns for clean rollback. A dedicated
  repository-layer testcontainers test
  (internal/repository/postgres/migration_000015_test.go) asserts the
  before/after FK action, column presence, index presence, and
  round-trip idempotency under up→down→up.

Domain — sentinel guard + dependency counts:
  internal/domain/connector.go gains IsRetired() on Agent, the
  exported SentinelAgentIDs slice listing server-scanner,
  cloud-aws-sm, cloud-azure-kv, cloud-gcp-sm verbatim (matching the
  four reserved IDs documented in CLAUDE.md and created at startup in
  cmd/server/main.go), IsSentinelAgent(id string) predicate,
  AgentDependencyCounts{ActiveTargets, ActiveCertificates,
  PendingJobs} with a HasDependencies() method, and ActorTypeAgent /
  ActorTypeSystem enum values used by audit emission downstream.
  Coverage locked down by internal/domain/connector_test.go.

Service — 8-step ordered contract:
  internal/service/agent_retire.go:RetireAgent(ctx, id, actor,
  opts{Force, Reason}) enforces a fixed execution order:
  (1) sentinel guard — IsSentinelAgent(id) returns ErrAgentIsSentinel
      unconditionally; force=true does NOT bypass it.
  (2) fetch — ErrAgentNotFound on miss.
  (3) idempotency — if IsRetired() already, return
      AgentRetirementResult{AlreadyRetired: true} with no new audit
      event and no state change (safe to replay from flaky clients).
  (4) preflight counts — collectAgentDependencyCounts runs
      ActiveTargets, ActiveCertificates, PendingJobs sequentially
      (not in parallel; keeps the per-query timeout predictable and
      matches the repo's existing call-chain shape).
  (5) force-reason guard — opts.Force=true with empty Reason returns
      ErrForceReasonRequired (wired into the 400 status surface).
  (6) dependency guard — HasDependencies() with opts.Force=false
      returns BlockedByDependenciesError{Counts} (wired into the 409
      body with per-bucket counts).
  (7) mutation — single pinned retiredAt := time.Now(); agent
      retirement first, then cascade target retirement if opts.Force,
      all under the repo's single transaction so the two retired_at
      stamps match to the second.
  (8) best-effort audit — agent_retired always; agent_retirement_
      cascaded additionally on the force path. Actor is whatever the
      handler resolves from the request; actor type is mapped by
      resolveActorType (system/agent-prefix→Agent/else→User). Audit
      emission failures are logged via slog.Error but do not abort
      the retirement (matches the house convention used by every
      other scheduler-emitted event).

  BlockedByDependenciesError implements Error() as
  "active_targets=%d, active_certificates=%d, pending_jobs=%d" and
  Unwrap() → ErrBlockedByDependencies. The single struct satisfies
  errors.Is via Unwrap (used by scheduler-level tests) and errors.As
  via the concrete type (used by the handler to fish out Counts for
  the 409 body). ListRetiredAgents(page, perPage) adds a separate
  paginated accessor with page<1→1 and perPage<1→50 normalization so
  retired rows are queryable without polluting the default agent
  listing.

  Sentinel guard coverage is asymmetric by design: all four reserved
  IDs are protected, and force=true cannot override. Regression tests
  in internal/service/agent_retire_test.go assert each of the eight
  steps in order, plus sentinel bypass attempts and idempotency
  replay.

Handler + router — status-code surface:
  internal/api/handler/agents.go:RetireAgent exposes seven status
  codes on DELETE /agents/{id}:
    200 on a fresh retirement (body echoes AgentRetirementResult).
    204 on idempotent replay (AlreadyRetired=true; no new audit).
    400 on ErrForceReasonRequired.
    403 on ErrAgentIsSentinel.
    404 on ErrAgentNotFound.
    409 on BlockedByDependenciesError, with a custom body shape
        {error, counts{active_targets, active_certificates,
        pending_jobs}} that bypasses the default ErrorWithRequestID
        envelope so callers get the per-bucket numbers directly.
    500 on any other error.
  Heartbeat HandleHeartbeat returns 410 Gone when the agent is
  retired (ErrAgentRetired), signalling the agent to shut down.
  Query params `force=true` and `reason=<text>` drive the cascade
  path; both are forwarded as url.Values through the new MCP
  transport.

  internal/api/router/router.go registers GET /api/v1/agents/retired
  literal-path BEFORE /api/v1/agents/{id} — Go 1.22 ServeMux's
  literal-beats-pattern-var precedence routes "retired" to the
  paginated retired-agents listing instead of fetching a hypothetical
  agent named "retired".

Agent binary — clean shutdown on 410:
  cmd/agent/main.go gains the ErrAgentRetired sentinel, a
  retiredOnce sync.Once, and a retiredSignal chan struct{}. A
  markRetired(source, statusCode, body) helper closes the channel
  exactly once; the Run() select loop observes the close and returns
  ErrAgentRetired; main() matches via errors.Is(err, ErrAgentRetired)
  and exits cleanly instead of spinning in the heartbeat retry loop.
  The 410 Gone surface is therefore terminal for the agent process.

MCP transport:
  internal/mcp/client.go adds Client.DeleteWithQuery(path, query),
  a new additive transport method. Client.Delete is path-only; without
  this method the retire tool would silently drop `force` and `reason`,
  turning every cascade retire into a default soft-retire. The new
  method shares do()'s 204 normalization and 4xx/5xx error
  propagation so tool authors get one contract.
  internal/mcp/tools.go + internal/mcp/types.go expose the
  retire_agent tool with Force+Reason inputs wired through
  DeleteWithQuery.

CLI:
  cmd/cli/main.go + internal/cli/client.go add two CLI surfaces:
  `agents list --retired` (client-side strip of --retired then
  delegation to ListRetiredAgents, sharing --page/--per-page parsing
  with the default listing) and `agents retire <id> [--force --reason
  "…"]` (mirrors ErrForceReasonRequired — force without reason is
  rejected client-side before the request is sent). JSON + table
  output modes both honor the new columns.

Frontend:
  web/src/pages/AgentsPage.tsx surfaces retired/retire affordances.
  web/src/api/client.ts + web/src/api/types.ts expose the retire
  endpoint and the retired-listing. 4 new Vitest regression cases.

OpenAPI:
  api/openapi.yaml documents DELETE /agents/{id} with all seven
  status codes, 410 on heartbeat, and the 409 per-bucket body shape.

Regression coverage (six new test files, all green):
  internal/service/agent_retire_test.go           — 8-step contract + sentinel guards
  internal/api/handler/agent_retire_handler_test.go — 7-status-code surface + 410 heartbeat
  internal/mcp/retire_agent_test.go               — DeleteWithQuery wire-through
  internal/cli/agent_retire_test.go               — --retired listing + --force/--reason pairing
  internal/repository/postgres/migration_000015_test.go — FK flip + columns + indexes + up↔down

shankar0123 b3cc7cbdb2 fix(policies): close the D-006 loop — TitleCase seed canonicals + severity-aware, config-consuming rule engine (D-008)
D-008 was a three-part drift in the policy engine that made the
D-005/D-006 remediation cosmetic below the DB layer:

  (a) migrations/seed.sql INSERTed rules with pre-D-005 lowercase
      types ('ownership', 'environment', 'lifetime', 'renewal_window')
      that the handler validator rejects on Create/Update but that
      raw SQL INSERTs bypassed entirely. At runtime evaluateRule's
      switch fell through to the default "unknown policy rule type"
      error branch on every demo rule × every cert × every cycle,
      flooding logs while emitting zero violations.

  (b) migrations/seed_demo.sql persisted lowercase severity values
      ('critical', 'error', 'warning') on policy_violations rows.
      INSERT succeeded because that column had no CHECK, but any
      frontend comparing against the canonical PolicySeverity enum
      mis-categorized every seeded violation.

  (c) evaluateRule hardcoded Severity: PolicySeverityWarning on
      every emitted violation and ignored rule.Config entirely —
      so the D-006 per-rule severity column (000013) and every
      per-arm Config JSON ({allowed_issuer_ids, allowed_domains,
      required_keys, allowed, lead_time_days, max_days}) was dead
      data below the evaluation layer.

This commit lands (a)+(b)+(c) atomically. Shipping any subset
leaves the feature half-working.

## Changes

Domain (internal/domain/policy.go):
  * Add PolicyTypeCertificateLifetime as the 6th TitleCase canonical.
    Pre-D-008 the seeded "max-certificate-lifetime" rule had no engine
    arm — routing it through RenewalLeadTime would conflate "how
    close to expiry before we renew" with "how long can the cert
    possibly be", two distinct semantics. The new type accepts
    config {"max_days": int} and flags certs whose
    NotAfter - NotBefore exceeds the cap.

Handler validator (internal/api/handler/validation.go):
  * ValidatePolicyType allowlist grown to 6 canonicals
    (AllowedIssuers, AllowedDomains, RequiredMetadata,
    AllowedEnvironments, RenewalLeadTime, CertificateLifetime).

OpenAPI (api/openapi.yaml):
  * PolicyType enum grown to match domain.

Frontend (web/src/api/types.ts, types.test.ts):
  * POLICY_TYPES tuple gains CertificateLifetime; pin test asserts
    all 6 canonicals and rejects casing drift.

Migration 000014 (policy_violations severity CHECK):
  * Named CHECK constraint (policy_violations_severity_check)
    mirroring 000013's allowlist, defense-in-depth at the DB layer
    against future drift from bypassed writes (migrations, psql
    sessions, future callers). Symmetric down migration drops by
    name.

Seed data:
  * migrations/seed.sql rewritten to emit TitleCase canonicals with
    per-arm config JSON that actually exercises the config-consuming
    paths (not the missing-field backstops):
      - pr-require-owner         → RequiredMetadata     {"required_keys":["owner"]}                        Warning
      - pr-allowed-environments  → AllowedEnvironments  {"allowed":["production","staging","development"]} Error
      - pr-max-certificate-lifetime → CertificateLifetime {"max_days":90}                                   Critical
      - pr-min-renewal-window    → RenewalLeadTime      {"lead_time_days":14}                              Warning
    Severities are now differentiated per rule (D-006 intent).
  * migrations/seed_demo.sql violation rows flipped to TitleCase
    severity ('Critical', 'Error', 'Warning') so migration 000014
    applies cleanly on upgrade paths.

Engine rewrite (internal/service/policy.go):
  * evaluateRule rewritten. All six arms now:
      1. Parse rule.Config into the per-arm typed struct.
      2. Bad JSON → log at ValidateCertificate boundary and skip
         this rule (no co-located poisoning of other rules in the
         same batch).
      3. Empty/null Config → emit the pre-D-008 missing-field
         violation (backwards compat invariant — operators who
         haven't reconfigured still see the same output).
      4. Violations emitted carry rule.Severity (no more hardcoded
         Warning); D-006 column is now load-bearing.
  * CertificateLifetime arm reads NotBefore/NotAfter from the
    certificate's latest version via CertRepo. Injected via
    PolicyService.SetCertRepo() setter — avoids churning ~36
    NewPolicyService call sites while keeping the lifetime arm
    optional (degrades to a log+skip if the setter is not wired).

Server wiring (cmd/server/main.go):
  * policyService.SetCertRepo(certRepo) wired after construction.

Tests (internal/service/policy_test.go):
  * 25 new subtests across 5 groups:
      - TestEvaluateRule_SeverityPassThrough (6): every rule type
        emits violations carrying rule.Severity, not hardcoded.
      - TestEvaluateRule_ConfigConsumed (12): every per-arm Config
        path exercised positive + negative.
      - TestEvaluateRule_EmptyConfig_BackCompat (3): empty/null
        Config still emits pre-D-008 missing-field violations.
      - TestEvaluateRule_BadConfig_SkipsRule: malformed JSON logs
        and skips cleanly without poisoning neighbors.
      - TestEvaluateRule_CertificateLifetime_RepoScenarios (3):
        ok when repo wired, log+skip when not, handles missing
        NotBefore/NotAfter edges.

Provenance: D-008 surfaced during D-005/D-006 remediation review
in eef1db0. That commit added persistence and CI pins for the
severity field but did not re-verify the evaluation layer
consumed it; this finding and fix close the audit-process gap.

shankar0123 eef1db0f0a fix(policies): stop 400ing the "+ New Policy" button + add per-rule severity (D-005, D-006)
Coverage Gap Audit findings D-005 (P0) + D-006 (P1) fixed together in a
single commit because they share the same root cause — policy CRUD sending
values the backend silently rejects — and splitting them would leave a
half-working UI between commits.

## D-005 (P0): PoliciesPage dropdown 400s every Create Policy

Root cause
----------
`web/src/pages/PoliciesPage.tsx` populated the Type `<select>` from a
hardcoded `['key_algorithm', 'ownership', 'allowed_issuers', ...]` array.
The backend's `internal/api/handler/validators.go::ValidatePolicyType`
enforces the TitleCase allowlist `AllowedIssuers`, `AllowedDomains`,
`RequiredMetadata`, `AllowedEnvironments`, `RenewalLeadTime` — defined in
`internal/domain/policy.go`. Every Create Policy request was rejected with
`400 invalid policy type`. The error surfaced only as a transient toast;
the modal closed anyway. Silent user-visible failure.

Fix
---
- `web/src/api/types.ts`: added `POLICY_TYPES` and `POLICY_SEVERITIES`
  tuples with `as const` and narrowed `PolicyRule.type`, `.severity`, and
  `PolicyViolation.severity` to the literal-union types. Dropdown is now
  sourced from the tuple; casing drift becomes a compile error.
- `web/src/pages/PoliciesPage.tsx`: rekeyed `severityStyles` /
  `severityDots` to the TitleCase values, added `humanize()` for display
  (AllowedIssuers → "Allowed Issuers"), removed the `badge-neutral`
  fallback that was papering over the mismatch.
- `web/src/api/types.test.ts` (new): pins both tuples exactly. If anyone
  edits one side of the frontend/backend contract without the other, CI
  fails with a clear assertion. Pure-TS vitest, no RTL dependency.

## D-006 (P1): `severity` field silently dropped on create/update

Root cause
----------
`PolicyRule` had no `Severity` field in `internal/domain/policy.go`. The
frontend has always sent `severity` on create/update, but Go's
`json.Decoder` (default settings, no `DisallowUnknownFields`) silently
dropped it. The value never reached PostgreSQL. Every rule rendered with
the same severity because there was no severity — just a display
computation downstream.

Fix: option (b), full-stack schema add (not delete-the-field)
-------------------------------------------------------------
- Migration `000013_policy_rule_severity` (up + down): adds
  `severity VARCHAR(50) NOT NULL DEFAULT 'Warning'` to `policy_rules` with
  CHECK constraint `severity IN ('Warning', 'Error', 'Critical')`. No
  index — three-value column on a low-thousands-rows table, planner will
  seq-scan regardless. PG 11+ metadata-only ADD COLUMN, safe on live data.
- `internal/domain/policy.go`: added `Severity PolicySeverity` field.
- `internal/repository/postgres/policy.go`: plumbed `severity` through
  ListRules SELECT + Scan, GetRule SELECT + Scan, CreateRule INSERT,
  UpdateRule UPDATE (4 queries).
- `internal/service/policy.go::UpdatePolicy`: if the client omits
  severity on a PUT (zero-value empty string), fetch the existing rule
  and preserve its severity. Without this, partial updates would trip the
  NOT NULL CHECK and 500. Preserves pre-existing behavior for Name/Type
  (out of scope).
- `internal/api/handler/policies.go::CreatePolicy`: default empty severity
  to `'Warning'`, then validate via `ValidatePolicySeverity`. 400 with
  clear message instead of 500 on CHECK violation. `UpdatePolicy`:
  validates severity only when provided.
- `internal/mcp/types.go` + `internal/mcp/tools.go`: added optional
  `severity` on the MCP `create_policy` / `update_policy` tool inputs so
  LLM callers stay in sync with the wire contract.
- `api/openapi.yaml`: added `severity` to the `PolicyRule` schema with
  the enum and default.

Acceptance criterion (user-defined)
-----------------------------------
"Create a rule with severity=Critical, reload the page, and still see
Critical — no silent drops." Verified end-to-end: frontend sends
`severity: "Critical"`, handler validates, service persists, DB stores,
GET returns, React renders the correct badge.

Seed data
---------
`migrations/seed.sql`: four demo rules now have differentiated severities
— `pr-require-owner` → Warning, `pr-allowed-environments` → Error,
`pr-max-certificate-lifetime` → Critical, `pr-min-renewal-window` →
Warning. The user called out that seeding all four at the same severity
makes the feature look decorative; differentiation demonstrates the
column carries real signal.

## Integration test fix (side effect of D-006)

`internal/integration/e2e_test.go::TestCrossResourceWorkflow/CreatePolicy`
was sending `"severity": "High"` — a value from the pre-audit severity
vocabulary that the new `ValidatePolicySeverity` correctly rejects with
400. Changed to `"Error"` (closest semantic match in the new TitleCase
allowlist). Only severity reference in the integration/ directory;
verified via grep.

## Out of scope, logged for follow-up (d/D-008)

Three policy-engine drift issues orthogonal to D-005 + D-006, explicitly
deferred per direction:

1. `migrations/seed.sql` policy_rules INSERTs use lowercase TYPE values
   (`'ownership'`, `'environment'`, `'lifetime'`, `'renewal_window'`).
   These are load-bearing on `internal/service/policy.go::evaluateRule`'s
   `switch rule.Type` (which also uses the lowercase strings). Migrating
   requires coordinated changes across seed + evaluation engine.
2. `migrations/seed_demo.sql:482-483` contains lowercase `'critical'`
   severity — will now fail the new CHECK constraint. Separate fix.
3. `evaluateRule` hardcodes `Severity: domain.PolicySeverityWarning` on
   emitted violations and ignores the configured `rule.Config`. The new
   severity column is read correctly on the CRUD path but not yet
   consulted during evaluation.

## Verification

Backend:
- `go build ./...` — clean
- `go vet ./...` — clean
- `go test -short ./...` — all packages green, including
  `internal/service` (policy service), `internal/api/handler` (policy +
  MCP handler tests), `internal/integration` (e2e_test.go after fix),
  `internal/domain`, `internal/repository/postgres`.

Frontend:
- `tsc --noEmit` — clean
- `vitest run` — 223/223 passing (4 new assertions in types.test.ts)
- `vite build` — clean (only the pre-existing chunk-size warning)

shankar0123 3f619bcaac feat(M49): Entrust, GlobalSign & EJBCA issuer connectors
Add three new issuer connectors completing commercial and open-source CA
coverage. Entrust uses mTLS client certificate auth with sync/async
issuance. GlobalSign Atlas uses mTLS + API key/secret dual auth with
serial-based tracking. EJBCA supports dual auth (mTLS or OAuth2) for
self-hosted Keyfactor CAs.

Each connector implements the full issuer.Connector interface (9 methods),
includes httptest-based unit tests (~14 each), and follows established
patterns (injectable HTTP clients, RFC 5280 revocation reason mapping,
CRL/OCSP delegated to CA).

Also includes: issuer factory cases, env var seeding, config structs,
domain types, seed data (3 rows, all disabled), OpenAPI enum updates,
frontend issuer catalog entries with config fields, and full docs
(connectors.md, architecture.md, features.md, README).

shankar0123 596d86a206 feat(M48): continuous TLS health monitoring — endpoint state machine, shared tlsprobe, 8 API endpoints, GUI
Adds continuous TLS endpoint health monitoring that closes the deploy→verify→monitor loop.
After M25 verifies a deployment succeeded once, M48 continuously confirms it stays healthy.

Key components:
- Shared `internal/tlsprobe/` package extracted from network scanner for reuse
- Health status state machine: healthy → degraded (2 failures) → down (5 failures),
  plus cert_mismatch when served fingerprint differs from expected
- 8th scheduler loop (60s tick, per-endpoint configurable intervals)
- PostgreSQL migration 000011: endpoint_health_checks + endpoint_health_history tables
- 8 REST API endpoints (CRUD, history, acknowledge, summary)
- Health Monitor GUI page with summary bar, status table, create modal, auto-refresh
- 38 new tests (5 tlsprobe + 11 domain + 10 service + 8 handler + 4 frontend)
- All coverage thresholds maintained (service 68%, handler 83%, domain 87%, middleware 63%)

shankar0123 f92c997a50 feat(M45): ACME certificate profile selection, ARI RFC 9773 renumber, 45-day renewal positioning
Three related ACME ecosystem changes shipped as a single milestone:

1. ACME Certificate Profile Selection: Custom JWS-signed newOrder POST with
   `profile` field (e.g., `tlsserver`, `shortlived` for 6-day certs) bypassing
   acme.Client.AuthorizeOrder() since golang.org/x/crypto lacks profile support.
   ES256 JWS signing with kid mode, nonce management, directory discovery.
   Empty profile delegates to standard library path (zero behavior change).
   Configurable via CERTCTL_ACME_PROFILE env var. GUI: profile dropdown on
   ACME issuer config.

2. ARI RFC 9702 → 9773 Renumber: All 25+ references updated across Go source,
   docs, README, and examples. Zero remaining occurrences of RFC 9702.

3. 45-Day / Short-Lived Certificate Positioning: 5 domain tests validating
   renewal thresholds against SC-081v3 validity reduction timeline (200→100→47
   days) and Let's Encrypt 45-day/6-day profiles. ARI (RFC 9773) is the
   expected renewal path for 6-day shortlived certs.

New tests: 13 profile + 5 domain threshold + 1 frontend = 19 new tests.

shankar0123 697c0be9f3 feat(M38): SSH target connector for agentless deployment via SSH/SFTP
Adds a new target connector enabling certificate deployment to any
Linux/Unix server without installing the certctl agent binary. Uses the
proxy agent pattern — a single agent in the same network zone deploys
certs to remote servers over SSH/SFTP.

Key additions:
- SSH/SFTP connector with key auth (file/inline) + password auth
- Injectable SSHClient interface for cross-platform testing (25 tests)
- Shell injection prevention via validation.ValidateShellCommand()
- Configurable cert/key/chain paths with octal permissions
- GUI: 11 SSH config fields in target create wizard

Also fixes pre-existing frontend bug where all target type strings
(nginx, apache, etc.) were sent as lowercase but the backend expects
proper-case (NGINX, Apache, etc.), breaking GUI-created targets.
Adds missing TargetTypeSSH to validTargetTypes service map.

shankar0123 995b72df05 feat(M34): dynamic issuer configuration with encrypted config storage
Replace static env-var-based issuer wiring with GUI-driven dynamic
configuration stored encrypted in PostgreSQL. Operators can now
configure, test, enable/disable, and manage issuers from the dashboard
without restarting the server.

Key changes:
- AES-256-GCM encryption for sensitive issuer config at rest (PBKDF2
  key derivation with 100k iterations)
- Dynamic IssuerRegistry with sync.RWMutex replacing static map
- Connector factory pattern (issuerfactory.NewFromConfig) replacing
  140 lines of static wiring in main.go
- Migration 000009: encrypted_config, last_tested_at, test_status,
  source columns on issuers table
- Env var seeding on first boot with ON CONFLICT DO NOTHING
- Registry Rebuild() for atomic map swap after CRUD operations
- Issuer type validation against domain constants on Create
- Audit trail for test connection results

shankar0123 11173a74c6 feat(M31): agent work routing — scope jobs to assigned agents
Deployment jobs now set agent_id from target→agent relationship at
creation time. GetPendingWork() uses ListPendingByAgentID() with a
3-way UNION query (direct match, legacy NULL fallback via target JOIN,
AwaitingCSR via cert→target→agent chain) so each agent only receives
its own jobs.

- Added AgentID *string to Job domain struct
- Added agent_id to all job SQL queries (5 SELECTs, INSERT, UPDATE, scanJob)
- New ListPendingByAgentID() repository method
- Rewrote GetPendingWork() from ~25 lines to single scoped query
- 4 new Go tests (3 agent routing + 1 deployment agent_id)
- Frontend: agent_id/target_id on Job type

shankar0123 a0afa7ab6f test(security): TICKET-018 add fuzz tests for command validation and domain parsing
Added Go native fuzz tests (testing/fuzz) for security-critical input validation:

1. FuzzValidateShellCommand in internal/validation/command_fuzz_test.go
   - Tests shell command validation with injection payloads (;, |, &, $, `, etc.)
   - Seed corpus includes valid commands and dangerous metacharacters
   - Ensures function never panics under fuzzing

2. FuzzValidateDomainName in internal/validation/command_fuzz_test.go
   - Tests RFC 1123 domain validation with wildcard support
   - Seed corpus includes SQL injection, path traversal, and malformed domains
   - Ensures function never panics under fuzzing

3. FuzzValidateACMEToken in internal/validation/command_fuzz_test.go
   - Tests base64url token validation
   - Seed corpus includes injection payloads and special characters
   - Ensures function never panics under fuzzing

4. FuzzIsValidRevocationReason in internal/domain/revocation_fuzz_test.go
   - Tests RFC 5280 revocation reason validation
   - Seed corpus includes case variations, injection attempts, and null bytes
   - Ensures function never panics and returns only valid booleans

5. FuzzCRLReasonCode in internal/domain/revocation_fuzz_test.go
   - Tests CRL reason code mapping
   - Validates return codes are within 0-9 range
   - Ensures invalid reasons default to 0 (unspecified)

All fuzz tests follow Go 1.18+ testing/fuzz conventions with seed corpus
for faster discovery of edge cases.

shankar0123 be72627aeb feat: M25 post-deployment TLS verification + M26 Traefik/Caddy targets
M25: After deploying a certificate, the agent probes the live TLS
endpoint and compares SHA-256 fingerprints to verify the correct cert
is being served. Best-effort — failures don't block deployments.
New endpoints: POST /jobs/{id}/verify, GET /jobs/{id}/verification.
Migration 000008 adds verification columns to jobs table.

M26: Traefik target connector (file provider, auto-reload) and Caddy
target connector (dual-mode: admin API hot-reload or file-based).
Both wired into agent dispatch.

Also: restructured README to highlight supported integrations (issuers,
targets, notifiers) earlier, moved API/CLI/MCP sections lower. Updated
all docs (features, connectors, architecture, testing guide, why-certctl)
and fixed integration tests for 18-param RegisterHandlers signature.

shankar0123 8308beb5bb fix: Docker Compose missing migrations, network scan []int crash, demo seed data
Three bugs fixed:
- Docker Compose only mounted migration 000001; migrations 000002-000007
  (profiles, agent groups, revocation, discovery, network scans) never ran,
  breaking half the demo features. Now mounts all 7 migrations in order.
- Network Scans page crashed with pq.Array scan error because lib/pq
  doesn't support []int, only []int64. Changed Ports field accordingly.
- Dashboard pie chart displayed "RenewalInProgress" without spaces.
  Added formatStatus() helper for PascalCase → spaced display.

Also adds first-run demo experience improvements:
- 9 discovered certificates (filesystem + network scan mix)
- 3 discovery scans with recent timestamps
- 2 AwaitingApproval renewal jobs for approval workflow demo
- CERTCTL_NETWORK_SCAN_ENABLED=true in Docker Compose
- Network scan targets seeded with last_scan results
- Version badge updated to v2.0.5
- Docs updated (quickstart, advanced demo) to reference seeded data

shankar0123 e19c240a79 feat: add ACME DNS-PERSIST-01 challenge support (IETF draft-ietf-acme-dns-persist)
Standing TXT record at _validation-persist.<domain> eliminates per-renewal
DNS updates. Auto-fallback to dns-01 if CA doesn't offer dns-persist-01.
ScriptDNSSolver extended with PresentPersist method. Configurable via
CERTCTL_ACME_CHALLENGE_TYPE=dns-persist-01 and
CERTCTL_ACME_DNS_PERSIST_ISSUER_DOMAIN env vars.

Also fixes IsExpired edge-case test in discovery_test.go that always failed
due to time.Now() drift between test setup and method invocation.

shankar0123 f5fed74d6f feat: M12 — sub-CA mode, ACME DNS-01 challenges, step-ca issuer connector
Sub-CA mode: Local CA loads CA cert+key from disk (CERTCTL_CA_CERT_PATH +
CERTCTL_CA_KEY_PATH) to operate as subordinate CA under enterprise root
(e.g., ADCS). Supports RSA, ECDSA, PKCS#8 keys. Validates IsCA and
KeyUsageCertSign. Falls back to self-signed when paths unset.

DNS-01 challenges: Pluggable DNSSolver interface with script-based hook
implementation. User-provided scripts create/cleanup _acme-challenge TXT
records for any DNS provider. Configurable propagation wait. Enables
wildcard certs and non-HTTP-accessible hosts.

step-ca connector: Smallstep private CA via native /sign API with JWK
provisioner auth. Issuance, renewal, revocation. Registered as iss-stepca.

23 new tests across 3 files. CI test path widened to ./internal/connector/issuer/...
