shankar0123 35e18bfc56 scheduler: bound renewal concurrency via CERTCTL_RENEWAL_CONCURRENCY
Closes the #9 acquisition-readiness blocker from the 2026-05-01 issuer
coverage audit. Pre-fix, JobService.ProcessPendingJobs ran every
claimed job sequentially in a single goroutine: safe but slow, and
operators with large fleets had no lever to dial throughput up.
Switching to fire-and-forget per-job goroutines would have unbounded
the upstream-CA call rate and tripped DigiCert / Entrust / Sectigo
rate limits — certctl's response to 429 was to retry on the next
tick, re-fanning out the same calls and digging deeper into the
limit. Operators need a knob.

This commit:

- Adds CERTCTL_RENEWAL_CONCURRENCY env var (default 25) loaded via
  the existing getEnvInt pattern in internal/config/config.go.
  Documented inline as the cap for the per-tick renewal/issuance/
  deployment goroutine fan-out, with operator-tuning guidance:
  permissive upstream limits + large fleets (>10k certs) → 100;
  strict limits or async-CA-heavy fleets → 25 or lower.

- Wires golang.org/x/sync/semaphore.Weighted around the per-job
  goroutine launch in JobService.ProcessPendingJobs. Acquire(ctx, 1)
  is the load-bearing piece — it BLOCKS the loop when at the cap,
  providing real backpressure rather than fire-and-forget. The
  fan-out is split into processPendingJobsSequential (legacy,
  preserved for unit-test wiring that doesn't call
  SetRenewalConcurrency) and processPendingJobsConcurrent (production,
  delegates to a generic boundedFanOut helper).

- boundedFanOut takes the per-job work as a closure so the cap can
  be tested directly without standing up the renewal/deployment
  service graph. processed/failed counters use atomic.Int64 to
  avoid mutex overhead on every job completion; final log line
  reads both AFTER wg.Wait so the counts reflect every dispatched
  job. ctx-aware Acquire ensures a shutdown ctx cancel interrupts
  the dispatch loop promptly; in-flight goroutines drain via Wait
  before the function returns so no goroutine outlives the
  scheduler tick.

- shouldSkipJob extracted as a package-private helper so the
  agent-routed-deployment skip logic is shared between the
  sequential and concurrent paths byte-for-byte (the audit prompt's
  "channel-based semaphore without ctx-aware acquire" anti-pattern
  is explicitly avoided — semaphore.Weighted.Acquire returns on ctx
  done; channel <- struct{}{} would block forever).

- SetRenewalConcurrency setter on JobService normalises ≤0 to 1.
  semaphore.NewWeighted(0) constructs a semaphore that blocks every
  Acquire forever; the normalisation prevents a misconfigured env
  var from wedging the scheduler.

- cmd/server/main.go wires SetRenewalConcurrency(cfg.Scheduler.
  RenewalConcurrency) on the freshly-built jobService, immediately
  after SetAuditService. Production deployments always take the
  bounded path; tests that build JobService directly via
  NewJobService keep their strict-sequential behaviour because
  renewalConcurrency is the zero value.

- Tests in internal/service/job_concurrency_test.go:
  * TestBoundedFanOut_CapHolds — primary regression guard. 50 jobs
    × 50ms work × cap=5 → asserts peak in-flight never exceeds 5
    AND reaches 5 at least once (catches both upper-bound regressions
    and gates that incorrectly cap below the configured value).
    Lock-free max via CompareAndSwap so the measurement instrument
    doesn't itself constrain concurrency.
  * TestBoundedFanOut_AllJobsRun — lower-bound: every non-skipped
    job is dispatched.
  * TestBoundedFanOut_SkipsAgentRoutedDeployments — pins the
    shouldSkipJob contract.
  * TestBoundedFanOut_CtxCancelInterrupts — ctx cancellation
    interrupts a stuck fan-out within the timeout budget.
  * TestBoundedFanOut_FailedJobsCounted — per-job errors don't
    abort the fan-out.
  * TestSetRenewalConcurrency_NormalizesNonPositive — ≤0 → 1 fail-safe
    pinned across negative/zero/positive inputs.

- docs/features.md: scheduler-loop table augmented with the
  concurrency-cap env-var pointer alongside the job-processor row.

- docs/architecture.md: Concurrency Safety section gains a paragraph
  explaining the cap, the operator-tuning guidance, the ctx-aware
  Acquire semantics, and the audit reference.

Operator-facing impact: the first big renewal sweep no longer
takes down the upstream CA's rate-limit budget. Existing deployments
get the bounded path automatically (default 25); operators can
override via env var without code changes.

shankar0123 fefa5a5fd7 acme: support serial-only revocation via local cert-version lookup
Closes the #7 acquisition-readiness blocker from the 2026-05-01 issuer
coverage audit. Pre-fix, ACME RevokeCertificate at acme.go:L519-L529
returned the literal error "ACME revocation by serial not supported in
V1; provide certificate DER". RFC 8555 §7.6 genuinely requires the
cert DER bytes (not just the serial), but a CLM platform's job is to
abstract over that limitation. Operators routinely have only the
serial in hand: lost PEM, rotated key, GUI revoke action driven by a
row in the certs list.

This commit:

- Adds CertificateLookupRepo interface at the ACME connector boundary
  (connector boundary, NOT a service/repository import — the connector
  accepts whatever satisfies the shape). Production wiring in
  cmd/server/main.go injects the postgres CertificateRepository; tests
  inject a fake.

- Adds CertificateRepository.GetVersionBySerial(ctx, issuerID, serial)
  + interface declaration in repository/interfaces.go, returning the
  certificate_versions row whose SerialNumber matches, scoped to the
  issuer via JOIN on managed_certificates. Mirrors the existing
  GetByIssuerAndSerial shape but returns the version (where PEMChain
  lives). Per RFC 5280 §5.2.3 the issuer scope is required for
  determinism.

- Adds SetCertificateLookup + SetIssuerID setters on *acme.Connector.
  Mirror the pattern local.Connector already uses for OCSP responder
  wiring. Both must be wired before serial-only revoke works;
  unwired state falls back to a more actionable error pointing at the
  wiring requirement (the historical "not supported" wording is
  retired).

- Rewrites RevokeCertificate end-to-end: lookup → empty-PEM check →
  pem.Decode → block.Type == "CERTIFICATE" check → ensureClient →
  golang.org/x/crypto/acme.Client.RevokeCert(ctx, accountKey, der,
  reasonCode). RFC 8555 §7.6 case 1 (revocation request signed with
  account key) — the same account key issued the cert, so authority
  is intrinsic. The not-found path returns an actionable operator-
  facing error pointing at the local-store requirement.

- Adds mapRevocationReason translating RFC 5280 §5.3.1 reason strings
  (unspecified, keyCompromise, cACompromise, affiliationChanged,
  superseded, cessationOfOperation, certificateHold, removeFromCRL,
  privilegeWithdrawn, aACompromise) into golang.org/x/crypto/acme.
  CRLReasonCode. Accepts canonical camelCase + underscore_lower +
  ALL_CAPS_UNDERSCORE. Nil reason → 0 (unspecified). Unknown reason
  errors rather than silently demoting (operators rely on the reason
  for compliance reporting).

- Wiring update in service/issuer_registry.go: SetACMECertLookup
  setter on the registry; Rebuild type-asserts *acme.Connector and
  calls SetCertificateLookup + SetIssuerID, mirroring the existing
  *local.Connector branch. cmd/server/main.go calls
  issuerRegistry.SetACMECertLookup(certificateRepo) immediately after
  SetIssuanceMetrics — the postgres repo satisfies the interface via
  GetVersionBySerial.

- Tests:
  * acme_revoke_test.go (new): TestRevokeCertificate_NoCertLookupWired,
    TestRevokeCertificate_NoIssuerIDWired,
    TestRevokeCertificate_LookupReturnsNotFound (operator-facing
    "may not have been issued through certctl" hint pinned),
    TestRevokeCertificate_LookupArbitraryError,
    TestRevokeCertificate_VersionPEMEmpty (corrupt-row guard),
    TestRevokeCertificate_PEMMalformed_NoBlock,
    TestRevokeCertificate_PEMMalformed_WrongType (PRIVATE KEY block
    rejected as not a CERTIFICATE).
  * TestMapRevocationReason_TableDriven: full RFC 5280 reason set
    plus camelCase / underscore / ALL-CAPS variants plus
    nil-reason and unknown-reason cases.
  * acme_failure_test.go: renamed TestRevokeCertificate_AlwaysError
    → TestRevokeCertificate_UnwiredCertLookupFallback; the test
    still exercises the same backward-compat branch but now
    asserts the new "CertificateLookup wiring" error wording.

- Mock-repo updates (3 sites): mockCertificateRepository in
  internal/integration/lifecycle_test.go, mockCertRepo in
  internal/service/testutil_test.go, mockCertRepoWithGetError in
  internal/service/shortlived_test.go each gain a GetVersionBySerial
  implementation that mirrors the GetByIssuerAndSerial logic but
  returns the version row.

- docs/connectors.md ACME section: new "Revocation by serial number"
  subsection covering the workflow, the local-store requirement
  (cert was issued through certctl, not imported), the reason-code
  mapping with the three accepted spelling variants, and a pointer
  to the audit reference.

Out of scope (intentional, per spec):

- Recovering the DER from outside the local cert store (CT logs,
  CSR + signature reconstruction). If the cert wasn't issued through
  certctl, revoke-by-serial via certctl isn't possible.
- Revocation via the cert's private key (RFC 8555 §7.6 case 2). The
  account-key path covers all certctl-issued certs because the same
  account key issued them.
- Pebble-backed integration test for the happy path. Pebble integration
  is the right home for that — the unit tests in this commit pin all
  failure-mode branches before the network call, and the wiring
  branch in Rebuild is exercised by the existing
  TestIssuerRegistryRebuild paths.

shankar0123 3b92048242 metrics: add per-issuer-type issuance counters, histogram, and failure classifier
Closes the #4 acquisition-readiness blocker from the 2026-05-01 issuer
coverage audit. Before this commit, certctl's Prometheus exposition had
zero per-issuer-type signal — operators answering "is DigiCert slow?"
or "is Sectigo failing more than ACME?" had to grep logs by issuer
name. This commit adds three series labelled by issuer type:

  certctl_issuance_total{issuer_type, outcome}
  certctl_issuance_duration_seconds{issuer_type}            (histogram)
  certctl_issuance_failures_total{issuer_type, error_class}

The histogram covers 0.05–120 second buckets to span the local-issuer
fast path and async-CA slow path (DigiCert/Sectigo/Entrust polling
can take minutes). error_class is a closed enum of eight values
(timeout, auth, rate_limited, validation, upstream_5xx, upstream_4xx,
network, other) classified once in service.ClassifyError. Cardinality
budget is ~276 new series, well within Prometheus's comfortable range.

Implementation:
- service.IssuanceMetrics is the thread-safe counter + histogram
  table. Three independent views (counters / failures / durations)
  exposed via SnapshotCounters / SnapshotFailures / SnapshotDurations.
  sync.RWMutex protects the map shape; per-key sync/atomic.Uint64
  primitives keep the recording hot path lock-free under concurrent
  service-layer goroutines.
- service.IssuanceCounterEntry / IssuanceFailureEntry /
  IssuanceDurationEntry / IssuanceMetricsSnapshotter live in service
  (not handler) to avoid an import cycle: handler already imports
  service for admin_est.go etc., so service can't import handler back.
  Handler's exposer takes the snapshotter via the service-defined
  interface.
- service.ClassifyError pure function maps error → error_class.
  context.DeadlineExceeded / context.Canceled → timeout; *net.OpError
  → network; substring matches against canonical AWS / DigiCert /
  Sectigo error shapes for auth / rate_limited / validation /
  upstream_5xx / upstream_4xx / network; unknown → other. Each branch
  has at least one representative test case in
  TestClassifyError.
- IssuerConnectorAdapter.SetMetrics wires per-adapter recording
  (issuerType + metrics). Existing 28+ test call sites of
  NewIssuerConnectorAdapter keep their one-arg signature; production
  wiring goes through SetMetrics post-construction.
- IssuerRegistry.SetIssuanceMetrics + Rebuild type-asserts to
  *IssuerConnectorAdapter and calls SetMetrics with the issuer type
  string. nil-guarded — tests that hand-build adapters without
  metrics get no-op recording.
- IssuerConnectorAdapter.IssueCertificate / RenewCertificate wrap the
  underlying connector call with start := time.Now() and
  recordIssuance(start, err). Renewal is recorded into the same
  certctl_issuance_* series as initial issuance — operationally,
  renewal IS issuance from the connector's perspective (matches the
  audit prompt's guidance on series naming).
- handler/metrics.go GetPrometheusMetrics gains a new exposer block
  emitting all three series in stable label order with correct
  Prometheus format (_bucket / _sum / _count for the histogram, +Inf
  bucket appended). Sorted via sort.Slice for stable output. nil-
  guarded so deploys without the wire produce clean exposition.
- formatLE helper trims trailing zeros from histogram bucket labels
  via strconv.FormatFloat(le, 'f', -1, 64) so the `le` labels match
  Prometheus client conventions ("0.05", "30", "120", not "0.0500"
  etc.).
- cmd/server/main.go wires a single IssuanceMetrics instance into
  both the IssuerRegistry (recording) and the MetricsHandler (exposer)
  using DefaultIssuanceBucketBoundaries.

Tests:
- TestIssuanceMetrics_RecordAndSnapshot — happy-path counter +
  histogram + failure recording, BucketBoundaries returns a copy
  (not shared storage).
- TestIssuanceMetrics_HistogramCumulative — pins the cumulative-buckets
  contract. 100ms observation lands in 0.1 bucket and every larger
  bucket; 750ms only in the 1.0 bucket. Off-by-one here would
  corrupt every quantile query downstream.
- TestIssuanceMetrics_Concurrency — 100 goroutines × 1000 ops under
  the race detector. Asserts atomic counter integrity across
  contended writes.
- TestClassifyError — 17 cases covering every branch of the closed
  enum plus the nil-error special case.

Implementation chooses the existing hand-rolled fmt.Fprintf
exposition pattern (no prometheus/client_golang dependency added)
to stay consistent with the OCSP / deploy counter blocks already in
the file.

Out of scope (separate follow-ups):
- Revocation metrics (certctl_revocation_*) — symmetric to issuance
  but the audit didn't ask; explicit follow-up commit.
- Discovery / health-check duration histograms.
- prometheus/client_golang migration.

shankar0123 b0efdbe2f8 repo,service: introduce WithinTx and atomic audit rows for issue/renew/revoke
Closes the #3 acquisition-readiness blocker from the 2026-05-01 issuer
coverage audit (Part 1.5 finding #1: audit row not transactional with
issuance). AuditRepository.Create previously ran on the package-level
*sql.DB while the certificate insert / version insert / revocation
insert ran on independent connections — a failed audit INSERT after
a successful operation INSERT was silently lost. SOX §404 over IT
general controls, PCI-DSS §10 audit logging, HIPAA §164.312(b) audit
controls, and CA/B Forum Baseline Requirements §5.4.1 audit log
records all presume audit-with-operation atomicity.

Design — Option A (Querier abstraction). The chosen pattern: a shared
repository.Querier interface (subset of *sql.DB and *sql.Tx) plus a
postgres.WithinTx helper that begins a tx, runs fn, commits on nil
error, rolls back on error or panic, and returns the wrapped result.
Repository methods that participate in a service-layer transaction
expose a *WithTx variant taking repository.Querier; the bare methods
remain for stand-alone use. A repository.Transactor abstracts the
"begin tx, run fn, commit/rollback" lifecycle so service-layer code
runs multi-write operations atomically without holding *sql.DB
directly. Option B (UnitOfWork) was considered but adds boilerplate
without behavioral benefit for the current scope. Option C
(context-carried tx) was explicitly rejected — it hides the
transactional boundary from the type system, reproducing the class
of bug we're fixing.

This commit:
- Adds internal/repository/querier.go with the Querier interface
  (compile-time guards that *sql.DB and *sql.Tx satisfy it) and the
  Transactor interface for service-layer use.
- Adds internal/repository/postgres/tx.go with the WithinTx helper
  (begin/fn/commit/rollback with panic recovery) and a transactor
  type that satisfies repository.Transactor.
- Adds CreateWithTx variants on AuditRepository, CertificateRepository
  (Create + Update + CreateVersion), and RevocationRepository.
  Existing bare methods now delegate to the *WithTx variant using
  the package-level *sql.DB so existing call sites are
  behavior-preserving.
- Updates repository/interfaces.go: AuditRepository, CertificateRepository,
  and RevocationRepository declare the new *WithTx methods. Adds an
  atomicity contract doc-comment on AuditRepository pointing at
  WithinTx + the audit blocker.
- Adds AuditService.RecordEventWithTx, mirroring RecordEvent but
  routing through CreateWithTx so the audit row is part of the
  caller's transaction. Same redaction + marshalling contract.
- Refactors three audit-emitting service paths to use Transactor.WithinTx
  when SetTransactor was wired, with a legacy fallback for backward
  compat:
    * CertificateService.Create — cert insert + audit row in one tx.
    * RevocationSvc.RevokeCertificateWithActor — cert status update +
      revocation row + audit row in one tx. The OCSP cache invalidate
      remains best-effort (out of scope per the prompt).
    * RenewalService CompleteServerRenewal — cert version insert +
      cert update + audit row in one tx. Job status update stays
      outside the audit-atomicity scope (job state lives outside
      the operator-facing audit trail).
- Adds SetTransactor on CertificateService, RevocationSvc, and
  RenewalService. cmd/server/main.go wires a single Transactor
  instance shared across all three so all audit-emitting paths run
  their writes in transactions backed by the same *sql.DB handle.
- Updates 5 mock implementations to satisfy the new interface methods:
  mockCertRepo (testutil_test.go), mockCertRepoWithGetError
  (shortlived_test.go), fakeRevocationRepo (crl_cache_test.go),
  intuneE2EAuditRepo (scep_intune_e2e_test.go), and the integration-
  test mocks (lifecycle_test.go: mockCertificateRepository,
  mockAuditRepository, mockRevocationRepository). All *WithTx mocks
  ignore the Querier and delegate to the bare method (mocks have no
  DB; in-memory state is shared regardless of "tx").
- Adds a service-layer test mockTransactor with BeginTxErr and
  CommitErr knobs so the atomic-audit tests can assert error
  propagation through the transactional boundary.
- Adds internal/repository/postgres/tx_test.go: unit-level test that
  WithinTx surfaces "begin tx" wrap when BeginTx fails, and that
  Transactor.WithinTx delegates correctly. Real-Postgres rollback
  semantics are covered by the testcontainers tests in the postgres
  package — sandbox disk pressure prevented adding a sqlmock dep
  for the in-fn / commit-failure unit test, so those scenarios are
  exercised through atomic_audit_test.go using the mockTransactor's
  CommitErr / BeginTxErr fields.
- Adds internal/service/atomic_audit_test.go:
    * TestCertificateService_Create_AtomicWithTx — asserts audit
      insert failure inside the tx surfaces as the operation's error
      (closes the blocker contract).
    * TestCertificateService_Create_LegacyPathLogs — pins the
      backward-compat behavior when SetTransactor isn't wired:
      audit failure is logged-not-failed, matching pre-fix.
    * TestCertificateService_Create_TransactorBeginFailure — BeginTx
      error path: operation fails, no cert insert, no audit insert.
    * TestCertificateService_Create_TransactorCommitFailure —
      Commit error after successful in-fn writes surfaces as the
      operation's error. Real Postgres can fail Commit on
      serialization conflicts; the service must report this.

Out of scope (separate follow-up commits, same shape):
- Issuer CRUD audit atomicity.
- Target CRUD audit atomicity.
- Agent retire (already transactional via RetireAgentWithCascade;
  verified, not changed).
- Renewal-policy CRUD audit atomicity.
- Owner/team/agent-group CRUD audit atomicity.
- Discovery / health-check audit atomicity.

shankar0123 2d83342bbe feat(metrics): extend /metrics/prometheus with per-area OCSP counters (Phase 8)
Production hardening II Phase 8 — surface the OCSP per-event counters
shipped in Phase 1+2 through the existing /api/v1/metrics/prometheus
endpoint. Operators now alert on certctl_ocsp_counter_total
{label="rate_limited"} (Phase 3 trip), {label="nonce_malformed"}
(Phase 1 reject), {label="signing_failed"} (issuer connector fails),
etc.

NEW interface CounterSnapshotter (handler/metrics.go) — minimum
surface the Prometheus exposer needs from any per-area counter table:
just Snapshot() map[string]uint64. service.OCSPCounters.Snapshot
(Phase 1) satisfies it; future per-area counters (CRL, cert-export,
EST per-profile, SCEP per-profile, Intune per-profile) plug in the
same way as separate SetXxxCounters setters.

Naming convention per frozen decision 0.10:
  certctl_<area>_counter_total{label="<event>"} <value>

This commit ships only the OCSP block. The remaining areas (CRL,
cert-export, EST, SCEP, Intune) plug in via the same
SetXxxCounters pattern in follow-up commits — the wire-up cost per
area is one new field + one setter + one block of fmt.Fprintf lines.
The bundle's S-1 docs-count guard means we don't claim a specific
total in prose; operators run `curl /api/v1/metrics/prometheus | grep
certctl_` to enumerate.

Wired in cmd/server/main.go: a single shared *service.OCSPCounters
instance is created once and passed to BOTH the
ocspResponseCacheService (so the cache hot path ticks counters) AND
metricsHandler.SetOCSPCounters (so the Prometheus exposer reads
them). Existing dashboard metrics (certctl_certificate_total,
certctl_agent_total, etc.) remain unchanged at the same line offsets
— back-compat preserved.

Pre-commit verification: go build ./... clean; go test -short
-count=1 green for handler/ + service/. The existing
TestGetPrometheusMetrics_Success tests still pass (the new counter
block is additive at the END of the response body, after the
existing dashboard metrics + uptime line).

shankar0123 ed19312df6 feat(ratelimit): per-endpoint rate limit on OCSP + cert-export (Phase 3)
Production hardening II Phase 3 — wire the existing
internal/ratelimit/SlidingWindowLimiter into the OCSP and cert-export
handlers. Removes the DoS vector where an unauthenticated relying
party (or compromised admin token) can hammer the responder /
key-export endpoint at unbounded rates.

OCSP: per-source-IP cap. Default 1000 req/min/IP, 50k tracked IPs
(matches the SCEP/Intune replay cache cap). Configurable via
CERTCTL_OCSP_RATE_LIMIT_PER_IP_MIN; zero disables. Source IP comes
from net.SplitHostPort(r.RemoteAddr) — we deliberately do NOT honor
X-Forwarded-For because OCSP is publicly reachable and untrusted
intermediaries could spoof the header to bypass the limit.

On rate-limit trip: respond with the canonical
ocsp.UnauthorizedErrorResponse pre-built blob from x/crypto/ocsp
(status 6 per RFC 6960 §2.3) plus Retry-After: 60. Using the
unauthorized status (instead of TryLater) avoids hand-rolling DER
for a single rejection path; relying parties retry on any non-good
status anyway.

Cert-export: per-actor cap. Default 50 exports/hr/operator.
Configurable via CERTCTL_CERT_EXPORT_RATE_LIMIT_PER_ACTOR_HR; zero
disables. Actor extracted from the X-Actor request header (set by
the auth middleware); falls back to RemoteAddr if empty (defensive).

On rate-limit trip: HTTP 429 + JSON body
{"error":"rate_limit_exceeded","retry_after_seconds":3600} +
Retry-After: 3600.

NEW config fields in internal/config/config.go::SchedulerConfig:
  OCSPRateLimitPerIPMin (default 1000)
  CertExportRateLimitPerActorHr (default 50)

WIRED in cmd/server/main.go: ocspLimiter constructed with the
configured cap, 1m window, 50k map cap; exportLimiter same shape with
1h window. Both wired via SetOCSPRateLimiter / SetExportRateLimiter
on their respective handlers. Existing deploys see no behavior
change unless the env vars are set to non-default values + traffic
exceeds the cap.

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

shankar0123 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.

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.

shankar0123 aa139ee0d9 EST RFC 7030 hardening master bundle Phases 2-4: end-to-end mTLS sibling
route + RFC 9266 channel binding + HTTP Basic enrollment-password +
per-source-IP failed-auth limit + per-(CN, sourceIP) sliding-window cap.

Two new shared packages so EST + Intune share infrastructure:
- internal/cms/ — RFC 9266 tls-exporter extractor (ExtractTLSExporter
  with stdlib-panic recovery for synthetic ConnectionStates) +
  CSR-side channel-binding parser via raw TBSCertificationRequestInfo
  walk (the stdlib's csr.Attributes can't represent the OCTET STRING
  binding value), VerifyChannelBinding composite, EmbedChannel-
  BindingAttribute fixture helper, typed sentinel errors for missing
  / mismatch / not-TLS-1.3 mapped to HTTP 400 / 409 / 426 in handler.
- internal/trustanchor/ — extracted from scep/intune/trust_anchor*.go
  so the EST mTLS sibling route + Intune dispatcher share the same
  SIGHUP-reloadable PEM bundle primitive. intune.TrustAnchorHolder
  is now `= trustanchor.Holder` (type alias) + NewTrustAnchorHolder =
  trustanchor.New (function alias) — every existing call site compiles
  unchanged. Intune's LoadTrustAnchor is a thin wrapper over
  trustanchor.LoadBundle. White-box tests moved to the new package.
- internal/ratelimit/ — extracted from scep/intune/rate_limit.go (this
  was Phase 4.1, in the same bundle). intune.PerDeviceRateLimiter
  is now a thin wrapper preserving the (subject, issuer)→key
  composition; EST handler reaches for SlidingWindowLimiter directly.

ESTHandler grew six optional fields wired by per-profile setters
(SetMTLSTrust / SetChannelBindingRequired / SetEnrollmentPassword /
SetSourceIPRateLimiter / SetPerPrincipalRateLimiter / SetLabelForLog)
plus four new mTLS-route methods (CACertsMTLS / SimpleEnrollMTLS /
SimpleReEnrollMTLS / CSRAttrsMTLS); shared internal pipeline
handleEnrollOrReEnroll(reEnroll, viaMTLS) keeps the auth/binding/
rate-limit gates DRY. New router method RegisterESTMTLSHandlers
registers /.well-known/est-mtls/<PathID>/{cacerts,simpleenroll,
simplereenroll,csrattrs}; AuthExemptDispatchPrefixes extends the
no-auth chain to /.well-known/est-mtls.

cmd/server/main.go's EST loop wires per-profile mTLS holder +
channel-binding policy + per-principal limiter + (when EnrollmentPassword
non-empty) Basic + source-IP limiter; new preflightESTMTLSClientCATrust-
Bundle returns *trustanchor.Holder so SIGHUP rotates the EST mTLS
bundle live without restart. SCEP + EST mTLS profiles now share a
single union mtlsUnionPoolForTLS passed to buildServerTLSConfigWithMTLS
(replaces the protocol-specific scepMTLSUnionPoolForTLS); per-handler
re-verify enforces "cert must chain to THIS profile's bundle" so
cross-protocol bleed is blocked at the application layer even though
the TLS layer trusts certs from either pool's union.

Phase 3.3 source-IP failed-Basic limiter defaults: 10 attempts / 1h
/ 50k tracked IPs (no env var; tunable in a follow-up). Phase 4.2
per-principal limiter cap from CERTCTL_EST_PROFILE_<NAME>_RATE_
LIMIT_PER_PRINCIPAL_24H (existing field, Phase 1 shipped).

New tests:
- internal/cms/channelbinding_test.go: extractor + CSR-side parser +
  composite + TLS-1.3 round-trip end-to-end + EmbedChannelBinding-
  Attribute round-trip
- internal/trustanchor/holder_test.go: parseBundlePEM white-box +
  LoadBundle + Holder Get/Pool/SetLabelForLog/Reload-happy/
  Reload-keeps-old-on-failure/Reload-keeps-old-on-expired/
  WatchSIGHUP-reloads-pool/WatchSIGHUP-stop-clean
- internal/api/handler/est_hardening_test.go: 16 named cases covering
  mTLS no-trust-pool 500 + no-cert 401 + cross-profile cert 401 +
  happy-path 200 + CACertsMTLS auth gate + CSRAttrsMTLS auth gate +
  channel-binding required-absent-rejected + not-required-absent-
  allowed + writeChannelBindingError mapping + Basic no-header 401

  no-gate + per-IP failed-attempt lockout 429 + per-principal

shankar0123 a808948397 feat(est): per-profile dispatch — multi-profile env-var family + back-compat shim
EST RFC 7030 hardening master bundle Phases 0 + 1 of 13. Lays the
foundation for the remaining hardening phases (mTLS auth, HTTP Basic
auth, channel binding, server-keygen, admin observability, GUI, libest
e2e) without changing existing operator behavior — backward-compat
shim preserves the v2.0.66 single-issuer flat env-var setup.

WHAT LANDS:

Phase 0 — Frozen decisions
  9 frozen decisions documented in
  cowork/est-rfc7030-hardening-prompt.md::Phase 0 frozen decisions
  (auth modes mTLS+Basic at GA; RFC 9266 channel binding; multi-profile
  env-var family CERTCTL_EST_PROFILES; mTLS sibling URL
  /.well-known/est-mtls/<pathID>; serverkeygen ships V2; fullcmc
  deferred; renewal device-driven per RFC 7030 §4.2.2; csrattrs
  algorithm allow-list profile-derived; libest as e2e reference).

Phase 1 — Multi-profile config + per-profile dispatch
  internal/config/config.go: extended ESTConfig with Profiles slice;
  added ESTProfileConfig struct with all field contracts (PathID +
  IssuerID + ProfileID + EnrollmentPassword + MTLSEnabled +
  MTLSClientCATrustBundlePath + ChannelBindingRequired +
  AllowedAuthModes + RateLimitPerPrincipal24h + ServerKeygenEnabled).
  Forward-looking fields (mTLS, HTTP Basic, channel binding,
  rate limit, server-keygen) are dormant in Phase 1 — Phase 2-5 wire
  the corresponding handlers; Validate() gates ensure operators can't
  set incoherent combinations (MTLSEnabled=true without bundle path,
  basic auth without password, mtls auth mode without MTLSEnabled,
  ChannelBindingRequired without mTLS, ServerKeygenEnabled without
  ProfileID).

  loadESTProfilesFromEnv: mirrors loadSCEPProfilesFromEnv exactly.
  Reads CERTCTL_EST_PROFILES=corp,iot,wifi and per-profile env vars
  CERTCTL_EST_PROFILE_<NAME>_*. Lowercase PathID, uppercase env-var
  name. parseAuthModes handles comma-separated normalization.

  mergeESTLegacyIntoProfiles: back-compat shim. When CERTCTL_EST_PROFILES
  is unset AND CERTCTL_EST_ENABLED=true, synthesizes a single-element
  Profiles[0] with PathID="" so existing /.well-known/est/
  operators see no behavior change.

  validESTPathID + validESTAuthMode: shape validators. PathID matches
  [a-z0-9-]+ with no leading/trailing hyphen (mirrors validSCEPPathID
  exactly). Auth mode is one of {mtls, basic}.

  Per-profile Validate(): refuses every documented misconfiguration
  with operator-greppable error messages naming the offending profile
  index + PathID + field. Mirrors the SCEP audit-closure pattern.

internal/api/router/router.go: refactored RegisterESTHandlers from
  single-handler to map[string]ESTHandler. Empty PathID maps to legacy
  /.well-known/est/ root (literal-string r.Register calls preserve
  openapi-parity scanner behavior). Non-empty PathIDs dynamic-register
  /.well-known/est/<pathID>/{cacerts,simpleenroll,simplereenroll,csrattrs}.
  Mirrors the SCEP per-profile dispatch from commit fdd424b.

cmd/server/main.go: refactored EST startup block to iterate
  cfg.EST.Profiles. Per-profile preflight (issuer-in-registry,
  preflightEnrollmentIssuer L-005 gate) runs in the loop with
  per-profile structured logging including PathID. Failures log the
  offending PathID so multi-profile deploys can pinpoint which broke
  startup. Mirrors the SCEP per-profile loop from commit fdd424b.

Updated 3 callers of the old single-handler signature:
  - internal/api/router/router_test.go::TestRegisterESTHandlers_AllPaths
  - internal/integration/lifecycle_test.go::setupTestServer
  - internal/integration/negative_test.go::setupTestServer
  Each wraps the existing single ESTHandler in a single-element
  map[string]handler.ESTHandler{"": estHandler} preserving exact
  legacy behavior.

NEW TESTS:

internal/config/config_est_profiles_test.go (12 tests):
  - LegacyFlatFields_SynthesizeSingleProfile (back-compat shim)
  - DisabledNoLegacyShim
  - MultipleProfiles_LoadFromEnv (3 profiles: corp+mtls+basic+keygen,
    iot+basic, wifi+mtls; verifies every field round-trips)
  - StructuredFormBeatsLegacy
  - PathIDValidation (12 sub-cases: empty/valid/leading-hyphen/
    trailing-hyphen/uppercase/slash/dot/underscore/space/percent)
  - DuplicatePathID_Refuses
  - MissingPerProfileIssuerID
  - MTLSEnabledRequiresBundlePath
  - ChannelBindingWithoutMTLS_Refuses (cross-check)
  - BasicAuthInModesRequiresPassword (cross-check)
  - MTLSAuthModeRequiresMTLSEnabled (cross-check)
  - UnknownAuthModeRefused
  - NegativeRateLimitRefused
  - ServerKeygenRequiresProfileID
  - DisabledIgnoresProfiles
  - ParseAuthModes_Normalization (8 sub-cases)

internal/api/router/router_est_profiles_test.go (4 tests):
  - LegacyEmptyPathIDMapsToRoot
  - NonEmptyPathIDMapsToSubpath
  - MultipleProfilesNoCrossBleed (the load-bearing dispatch invariant —
    each profile's PathID routes to its OWN handler instance,
    proven via per-profile-tagged mock responses with base64 prefix
    matching)
  - EmptyMapRegistersNoRoutes

VERIFICATION (sandbox, Go 1.25.9):
  gofmt -l                — clean for all changed files
  staticcheck             — clean for config + router + handler +
                            integration + cmd/server packages
  go vet                  — clean for the same packages
  go test -short -count=1 — green for config, router, handler,
                            service, integration, cmd/server

NEXT (Phase 2): mTLS client cert auth + TrustAnchorHolder + RFC 9266
tls-exporter channel binding. Phase 1's Validate gates already refuse
the incoherent configurations Phase 2 must defend against; Phase 2
adds the actual TLS-listener wiring + handler-side cert validation +
channel-binding extraction.

shankar0123 530593507b fix(scep-intune): close 11 audit gaps from 2026-04-29 pre-tag review
Closes the eleven gaps identified in the pre-v2.1.0 audit of the SCEP
RFC 8894 + Intune master bundle (cowork/scep-bundle-gap-closure-prompt.md).
Constitutional rule from cowork/CLAUDE.md::Operating Rules — 'Always
take the complete path, not the easy path' — drove this closure: each
gap was a load-bearing wire that crossed multiple layers (config →
validator → service wire-up → tests → docs) and shipping the bundle
without them would have produced lying-field footguns where operator-
visible config options stored values without affecting behavior.

WHAT LANDS:

Phase A — Clock-skew tolerance (master prompt §15 hazard closure)
  internal/scep/intune/challenge.go: ValidateChallenge migrated from
  positional args to ValidateOptions{} struct; new ClockSkewTolerance
  field with default 0 (strict). 24 call sites updated mechanically.
  Asymmetric application: now+tolerance >= iat AND now-tolerance < exp.
  internal/config/config.go: SCEPIntuneProfileConfig.ClockSkewTolerance
  default 60s + Validate() refusal when >= ChallengeValidity.
  cmd/server/main.go: SetIntuneIntegration signature extended;
  per-profile env-var loader honors CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CLOCK_SKEW_TOLERANCE.
  internal/service/scep.go: intuneClockSkew field + IntuneStatsSnapshot
  surfaces clock_skew_tolerance_ns. web/src/api/types.ts mirrors.
  4 new tests in challenge_test.go covering accept-within-tolerance,
  reject-beyond-tolerance, accept-expired-within-tolerance,
  negative-treated-as-zero defensive normalization.
  docs/scep-intune.md updated with the new env var + time-bounds rule.

Phase B — unknown-version-rejected golden test
  internal/scep/intune/golden_helper_test.go: goldenUnknownVersionPayload
  helper + signGoldenChallengeAny generic signer.
  challenge_golden_test.go: TestGoldenChallenge_UnknownVersionRejected
  uses an in-process ECDSA fixture (the on-disk PEM was generated with
  a Go-stdlib version that produces different ecdsa.GenerateKey bytes
  from the current call). TestRegenerateGoldenFixtures emits the new
  unknown_version fixture file too.

Phase C — Two named Intune e2e tests
  internal/api/handler/scep_intune_e2e_test.go:
    TestSCEPIntuneEnrollment_RateLimited_E2E (cap=2 + 3 attempts; 3rd
    returns FAILURE+badRequest with rate_limited counter ticked)
    TestSCEPIntuneEnrollment_TrustAnchorSIGHUPReload_E2E (rotate
    on-disk PEM + holder.Reload(); old-key challenge fails with
    badMessageCheck; signature_invalid counter ticked)
  intuneE2EFixture struct extended with trustHolder + trustPath fields
  so tests can rotate.

Phase D — Four new ChromeOS hermetic tests (10 total now)
  internal/api/handler/scep_chromeos_test.go:
    _RAKeyMismatch — PKIMessage encrypted to wrong RA cert; handler
      rejects without reaching service.
    _3DESBackwardCompat — RFC 8894 §3.5.2 legacy fallback verified.
    _RSACSR + _ECDSACSR — explicit matrix-pair pinning.
  buildTestECDSACSR helper for ECDSA P-256 CSR construction;
  tripleDESCBCEncrypt mirrors aesCBCEncrypt for 3DES-CBC;
  assertChromeOSPositiveCertRep shared assertion.

Phase E — Per-profile counter isolation test
  internal/api/handler/scep_profile_counter_isolation_test.go:
    TestSCEPHandler_PerProfileIntuneCountersIsolated wires two
    SCEPService instances + drives distinct PKIMessages + asserts
    counter isolation. Guards against a future cmd/server/main.go
    refactor that shares a *intuneCounterTab across profiles.
  buildPerProfileIntuneFixture parameterized helper.

Phase F — Server-boot regression tests
  cmd/server/preflight_scep_intune_test.go: 3 named tests covering
  disabled-backward-compat, broken-config-with-PathID, expired-cert
  refusal. preflightSCEPIntuneTrustAnchor signature extended with
  pathID arg so error messages carry PathID= for operator log-grep.

Phase G — docs/connectors.md
  Four new subsections under §EST/SCEP Integration: multi-profile
  dispatch + mTLS sibling route + Intune Connector dispatcher + SCEP
  probe in network scanner. Each has a one-paragraph operator
  explanation + an env-var or endpoint table.

Phase H — Coverage uplift
  internal/service/scep_probe_persist_test.go: 5 unit tests on
  persistProbeResult (nil-safe + nil-repo-safe + repo-error swallow +
  nil-logger guard) + ListRecentSCEPProbes (empty-slice-not-nil + repo
  pass-through) + describeCertAlgorithm (RSA/ECDSA/QF1008-nil-curve
  defensive branch/Ed25519/DSA/empty). CI gates (service ≥70, handler
  ≥75) PASS at 70.9% / 79.3%.

Phase I — deploy/test integration variant
  deploy/test/scep_intune_e2e_test.go (//go:build integration):
    TestSCEPIntuneEnrollment_Integration + _RateLimited_Integration
    against the live docker-compose certctl container. Skip-when-
    stack-missing semantics so sandbox + CI both work.
  deploy/docker-compose.test.yml: new e2eintune SCEP profile env
  vars + bind-mount of deploy/test/fixtures/.
  deploy/test/fixtures/README.md: documents the deterministic trust
  anchor regeneration recipe.

VERIFICATION (sandbox):
  gofmt -d        — clean for all changed files
  staticcheck     — clean for intune + handler + config + service +
                    cmd/server packages

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 0be889ff1d refactor(scep-gui): rebrand SCEP admin surface to per-profile tabbed interface (Profiles + Intune + Recent Activity)
Phase 9 follow-up to the SCEP RFC 8894 + Intune master bundle. The
Phase 9.4 GUI shipped 'SCEP Intune Monitoring' at /scep/intune, which
made the per-profile observability surface look Intune-only — operators
running EJBCA + Jamf would never click that nav link expecting per-
profile RA cert + mTLS observability. The page is per-profile keyed
under the hood; this commit rebrands + restructures so the surface
matches what operators actually need.

Spec: cowork/scep-gui-restructure-prompt.md.

User-visible change:

  - Nav link renamed: 'SCEP Intune' → 'SCEP Admin'.
  - Route: /scep is the new canonical path; /scep/intune kept as a
    backward-compat alias that lands directly on the Intune tab.
  - Page header: 'SCEP Administration'.
  - Three tabs:
      * Profiles (default) — per-profile lean cards with RA cert
        expiry countdown, mTLS sibling-route status badge, Intune
        enabled/disabled badge, challenge-password-set indicator.
        'View Intune details →' link on Intune-enabled cards
        deep-links into the Intune tab.
      * Intune Monitoring — the existing Phase 9.4 deep-dive
        (per-status counters, trust anchor expiry, recent failures
        table, reload-trust button + confirmation modal).
      * Recent Activity — full SCEP audit log filter merging all
        four action codes (scep_pkcsreq + scep_renewalreq +
        scep_pkcsreq_intune + scep_renewalreq_intune); chip filters
        for All / Initial / Renewal / Intune / Static.

Backend:

  * internal/service/scep.go — new SCEPProfileStatsSnapshot type +
    IntuneSection sub-block + ProfileStats(now) accessor. Adds
    raCertSubject/raCertNotBefore/raCertNotAfter + mtlsEnabled +
    mtlsTrustBundlePath fields with SetRACert + SetMTLSConfig setters.
    Existing IntuneStatsSnapshot + IntuneStats(now) preserved
    UNCHANGED for /admin/scep/intune/stats backward compat (the
    JSON shape stays byte-stable for external consumers — the
    aliasing approach the prompt initially suggested doesn't work
    because the new shape nests Intune while the old one is flat).
    ChallengePasswordSet is derived from challengePassword != ''
    (the secret value itself is never surfaced).

  * internal/api/handler/admin_scep_intune.go — new Profiles handler
    method on AdminSCEPIntuneHandler with the same M-008 admin gate.
    AdminSCEPIntuneServiceImpl extended (in place; same
    map[string]*service.SCEPService) to satisfy the new
    AdminSCEPProfileService interface. Single handler file gets the
    third method so the M-008 pin entry count stays steady (no new
    file, no new triplet of admin-gate test files — just three new
    Profiles tests inside the existing test file).

  * internal/api/router/router.go — one new route
    'GET /api/v1/admin/scep/profiles' registered to
    reg.AdminSCEPIntune.Profiles. HandlerRegistry unchanged.

  * api/openapi.yaml — new operation 'listSCEPProfiles' documenting
    the request body / response shape / error mapping. Existing
    Intune entries unchanged.

  * cmd/server/main.go — per-profile loop now calls
    scepService.SetMTLSConfig(profile.MTLSEnabled,
    profile.MTLSClientCATrustBundlePath) right after SetPathID, and
    scepService.SetRACert(raCert) right after loadSCEPRAPair returns
    the leaf cert. Both setters are nil-safe.

  * internal/api/handler/m008_admin_gate_test.go — extended the
    existing admin_scep_intune.go entry's justification to mention
    the third endpoint. No new map entry needed (file already
    listed).

Backend tests (8 new):

  * TestAdminSCEPProfiles_NonAdmin_Returns403
  * TestAdminSCEPProfiles_AdminExplicitFalse_Returns403
  * TestAdminSCEPProfiles_AdminPermitted_ForwardsActor — also pins
    that Intune-enabled profiles emit an 'intune' sub-block while
    Intune-disabled profiles OMIT it.
  * TestAdminSCEPProfiles_RejectsNonGetMethod
  * TestAdminSCEPProfiles_PropagatesServiceError
  * TestAdminSCEPProfilesServiceImpl_NilMapReturnsEmpty
  * (existing 16 Phase 9 admin tests still pass — backward-compat
    preserved)

Frontend:

  * web/src/api/types.ts — new SCEPProfileStatsSnapshot +
    IntuneSection + SCEPProfilesResponse types. Existing
    IntuneStatsSnapshot et al unchanged.
  * web/src/api/client.ts — new getAdminSCEPProfiles helper.
  * web/src/pages/SCEPAdminPage.tsx — full rewrite as the tabbed
    surface. Reuses the existing ConfirmReloadModal and Intune
    deep-dive card components verbatim; adds ProfileSummaryCard
    (lean card for the Profiles tab) and ActivityTab. URL state
    sync via useSearchParams so deep links survive reloads + browser
    back/forward. The legacy /scep/intune route alias defaults the
    activeTab to 'intune' on mount.
  * web/src/main.tsx — new <Route path='scep' /> + preserved
    <Route path='scep/intune' /> alias. Both render SCEPAdminPage.
  * web/src/components/Layout.tsx — nav link rebranded:
    label 'SCEP Intune' → 'SCEP Admin', to '/scep/intune' → '/scep'.

Frontend tests (20 — full rebuild):

  * Admin gate (non-admin sees gated banner + zero admin API calls)
  * Profiles tab default + Intune tab tabswitch + ?tab=intune deep
    link + legacy /scep/intune alias all land on Intune
  * Profiles tab status badges (Intune + mTLS + challenge-set)
    reflect each profile's flags
  * RA cert expiry tone bands (good ≥30d / warn 7-30d / bad <7d /
    EXPIRED) verified across three fixture profiles
  * 'View Intune details →' only renders for Intune-enabled
    profiles AND switches tabs on click
  * Empty-state banner when no profiles configured
  * Intune tab counters render with the existing Phase 9 deep-dive
    shape; reload modal Open/Confirm/Cancel/Error paths all pinned
  * Recent Activity tab merges all four SCEP audit actions across
    four parallel useQuery calls; filter chips
    (all/initial/renewal/intune/static) narrow correctly
  * Error path surfaces ErrorState on the active tab

Docs:

  * docs/scep-intune.md — Operational monitoring section heading
    expanded to '(SCEP Administration → Intune Monitoring tab)'.
    Page-surface description rewritten for the tabbed shape;
    admin-endpoints list extended with the new /admin/scep/profiles
    entry.
  * docs/architecture.md — Microsoft Intune Connector trust anchor
    subsection updated to reference the Intune Monitoring tab inside
    the SCEP Administration page + lists all three admin endpoints.
  * docs/legacy-est-scep.md — forward-ref expanded with a parallel
    sentence for the per-profile observability surface (independent
    of Intune).
  * README.md — Enrollment Protocols bullet for Intune updated to
    'admin GUI SCEP Administration page at /scep' with the three
    tabs called out.

Verification:
  * gofmt clean on touched files
  * go vet ./... clean
  * staticcheck on intune+service+handler+router+cmd-server clean
  * go test -short across intune+service+handler+router+cmd-server:
    all green (existing Phase 9 tests + new Profiles tests)
  * Frontend tsc --noEmit clean
  * Vitest: 20/20 SCEPAdminPage tests + 3/3 sibling AuditPage tests
    pass
  * G-3 docs-drift CI guard reproduced locally: clean (no new env
    vars; existing CERTCTL_SCEP_ allowlist prefix covers everything)
  * M-009 hard-zero useMutation guard reproduced locally: clean
    (the existing reload mutation already used useTrackedMutation
    from the Phase 9 follow-up commit 28e277a)
  * openapi-parity test green (new GET /api/v1/admin/scep/profiles
    operation documented)
  * M-008 admin-gate scanner green (existing admin_scep_intune.go
    entry covers all three handler methods; the test scanner
    enforces the triplet by file, not by endpoint, and the new
    Profiles triplet was added to the existing test file)

Backward compat preserved:
  * /api/v1/admin/scep/intune/stats unchanged — same JSON shape,
    same error codes, same M-008 gate
  * /api/v1/admin/scep/intune/reload-trust unchanged
  * /scep/intune route still works (alias to /scep with activeTab=intune)
  * IntuneStatsSnapshot Go type unchanged
  * IntuneStats(now) accessor unchanged

shankar0123 77e0281a0e feat(scep-intune): GUI monitoring tab + admin endpoints
Phase 9 of the SCEP RFC 8894 + Intune master bundle. Lands the operator-
facing Intune Monitoring tab plus the two admin-gated endpoints it reads
from. Per the constitutional 'complete path' rule: counters tick on
every typed dispatcher branch, the GUI poll is live (30s for stats,
60s for the audit log filter), and the SIGHUP-equivalent reload action
is one click + a confirmation modal — no follow-up plumbing required.

Backend (Phase 9.1 + 9.2 + 9.3):

  * internal/service/scep.go gains:
    - intuneCounterTab — atomic per-status counters keyed by the same
      labels intuneFailReason() emits (success / signature_invalid /
      expired / not_yet_valid / wrong_audience / replay / rate_limited /
      claim_mismatch / compliance_failed / malformed / unknown_version).
      Lock-free on the dispatcher hot path; snapshot() returns a
      zero-allocation map for the admin endpoint.
    - dispatchIntuneChallenge wires intuneCounters.inc(...) on every
      typed return path INCLUDING the success leg (credited before
      processEnrollment so a downstream issuer-connector failure
      doesn't double-count).
    - SetPathID + PathID accessors (so admin rows surface the SCEP
      profile path ID per row).
    - IntuneStatsSnapshot + IntuneTrustAnchorInfo public types, plus
      IntuneStats(now) accessor that walks the trust holder pool and
      packages a per-profile snapshot. ReloadIntuneTrust() is the
      typed wrapper around TrustAnchorHolder.Reload that returns
      ErrSCEPProfileIntuneDisabled when called on a profile where
      Intune isn't enabled (admin endpoint maps that to HTTP 409).

  * internal/api/handler/admin_scep_intune.go:
    - AdminSCEPIntuneService narrow interface (Stats + ReloadTrust)
      so the handler depends on a small surface; AdminSCEPIntuneServiceImpl
      is the production walker over the per-profile SCEPService map.
    - AdminSCEPIntuneHandler.Stats handles GET /api/v1/admin/scep/intune/stats
      with the M-008 admin gate (non-admin → 403 + service never
      invoked); returns {profiles, profile_count, generated_at}.
    - AdminSCEPIntuneHandler.ReloadTrust handles POST
      /api/v1/admin/scep/intune/reload-trust. Body is {path_id: '<id>'};
      empty body targets the legacy /scep root profile. Returns 200 on
      success / 404 on unknown PathID / 409 when the profile is Intune-
      disabled / 500 on a parse error from intune.LoadTrustAnchor (the
      holder retains its previous pool — fail-safe). 400 on malformed
      JSON.
    - ErrAdminSCEPProfileNotFound typed error so the handler can
      distinguish 'wrong profile' from 'broken file'.

  * internal/api/router/router.go: HandlerRegistry gains
    AdminSCEPIntune; both routes registered as bearer-auth-required
    (the admin-gate is at the handler layer per the M-008 pattern).

  * cmd/server/main.go: declares scepServices map[string]*service.SCEPService
    BEFORE HandlerRegistry construction so the same map can be referenced
    from both the admin handler (constructed early) and the SCEP startup
    loop (which populates it later by reference). The per-profile loop
    now calls scepService.SetPathID(profile.PathID) and stores the service
    pointer into the shared map. AdminSCEPIntune handler is constructed
    at the same time as AdminCRLCache.

  * internal/api/handler/m008_admin_gate_test.go: AdminGatedHandlers
    map gains 'admin_scep_intune.go' with a one-line justification —
    the regression scanner enforces the per-handler test triplet
    (TestAdminSCEPIntune_NonAdmin_Returns403 + _AdminExplicitFalse_Returns403
    + _AdminPermitted_ForwardsActor) plus their POST siblings for
    ReloadTrust.

  * api/openapi.yaml: documents both endpoints with request body /
    response shape / error mapping; openapi-parity-test now matches
    the registered routes.

Frontend (Phase 9.4):

  * web/src/pages/SCEPAdminPage.tsx — single-page Intune Monitoring
    surface:
    - Per-profile cards (one card per SCEP profile). Enabled profiles
      get the full counter grid + trust-anchor-expiry badge tone
      (good ≥30d / warn 7-30d / bad <7d / EXPIRED). Disabled profiles
      get an off-state pill with the env-var hint to opt in.
    - Counters polled every 30s via TanStack Query against
      GET /admin/scep/intune/stats.
    - Recent failures table (last 50) populated from the audit log
      filtered to action=scep_pkcsreq_intune AND scep_renewalreq_intune;
      merged + sorted by timestamp descending. Polled every 60s.
    - Reload trust anchor button per profile + confirmation modal that
      explains the SIGHUP equivalence and the fail-safe behavior.
      onConfirm runs a TanStack mutation, refetches the stats query
      on success, surfaces the underlying error (eg 'trust anchor
      cert expired') in the modal on failure (modal stays open so
      operator can retry).
    - Admin gate: when authRequired && !admin the page renders an
      'Admin access required' banner and the underlying admin API
      requests are never issued (React Query enabled flag gated on
      auth.admin) — server-side enforcement is M-008.

  * web/src/api/types.ts: IntuneStatsSnapshot + IntuneTrustAnchorInfo +
    IntuneStatsResponse + IntuneReloadTrustResponse.

  * web/src/api/client.ts: getAdminSCEPIntuneStats +
    reloadAdminSCEPIntuneTrust(pathID).

  * web/src/main.tsx: new route /scep/intune. The route is unconditional;
    the gating is at the page level so deep-links land cleanly.

  * web/src/components/Layout.tsx: 'SCEP Intune' nav link between
    Observability and Audit Trail with the appropriate sidebar icon.

Tests (Phase 9.5):

  * internal/api/handler/admin_scep_intune_test.go (16 tests):
    - M-008 admin-gate triplet for both Stats (GET) and ReloadTrust
      (POST): NonAdmin / AdminExplicitFalse / AdminPermitted.
    - Method-gate tests (Stats rejects POST, ReloadTrust rejects GET).
    - Stats propagates service errors as 500.
    - ReloadTrust maps ErrAdminSCEPProfileNotFound→404,
      ErrSCEPProfileIntuneDisabled→409, generic err→500.
    - Empty body targets legacy root PathID.
    - Malformed JSON→400.
    - AdminSCEPIntuneServiceImpl handles nil map + unknown PathID.

  * web/src/pages/SCEPAdminPage.test.tsx (13 tests):
    - Admin gate (non-admin sees gated banner + zero admin API calls;
      admin sees the page; no-auth dev mode also passes).
    - Profile rendering (counters with correct labels, expiry badge
      tone for ≥30d / EXPIRED states, off-state pill for disabled
      profiles, empty-state banner when no profiles configured).
    - Reload modal (opens on click, calls mutation on Confirm,
      keeps modal open + shows error on failure, Cancel skips
      mutation).
    - Error path renders ErrorState with retry.
    - Audit log filter merges PKCSReq + RenewalReq events and sorts
      descending.

Verification:

  * gofmt clean on touched files
  * go vet ./... clean
  * staticcheck on intune/service/api/cmd-server clean
  * go test -short across api+service+intune+cmd-server: all green
  * web tsc --noEmit clean
  * Vitest: SCEPAdminPage.test.tsx 13/13 + sibling page suites all
    pass
  * G-3 docs-drift CI guard: Phase 9 adds no new CERTCTL_* env vars
    so the guard does not fire
  * openapi-parity-test green (both new admin endpoints documented)
  * M-008 regression scanner enforces the per-handler test triplet —
    pin updated, all triplets present

shankar0123 7612da783a feat(scep-intune): per-profile dispatcher + SIGHUP reload + per-device rate limit + compliance hook seam
Phase 8 of the SCEP RFC 8894 + Intune master bundle. Wires the
internal/scep/intune validator from Phase 7 into the SCEPService
dispatch path, with a SIGHUP-reloadable trust anchor holder, a
per-(Subject, Issuer) sliding-window rate limiter, and a nil-default
ComplianceCheck seam for V3-Pro.

Operator-visible surface (per-profile, all default to off):

  CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_ENABLED=true
  CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CONNECTOR_CERT_PATH=/etc/certctl/intune.pem
  CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_AUDIENCE=https://certctl.example.com/scep/corp
  CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CHALLENGE_VALIDITY=60m
  CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_PER_DEVICE_RATE_LIMIT_24H=3

Per-profile dispatch (Phase 8.8): an operator running corp-laptops
through Intune AND IoT devices through static challenge configures
INTUNE_ENABLED=true on the corp profile only — the IoT profile's
PKCSReq path skips the dispatcher entirely. Mirrors the per-profile
shape established by Phase 1.5.

Wire-in surfaces:

  * config.go (Phase 8.1): SCEPProfileConfig.Intune sub-config of
    type SCEPIntuneProfileConfig (Enabled/ConnectorCertPath/Audience/
    ChallengeValidity/PerDeviceRateLimit24h). Loaded from the indexed
    CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_* env-var family. Per-profile
    Validate gate refuses INTUNE_ENABLED=true with empty ConnectorCertPath
    OR negative PerDeviceRateLimit24h.

  * cmd/server/main.go (Phase 8.2 + wire-in): preflightSCEPIntuneTrustAnchor
    helper mirrors preflightSCEPRACertKey/preflightSCEPMTLSTrustBundle
    shape — fail-loud at boot when the trust anchor file is missing /
    unreadable / empty / contains an expired cert. The per-profile loop
    builds the holder + replay cache + rate limiter, calls
    SetIntuneIntegration on the SCEPService, and starts the SIGHUP
    watcher. A deferred sweep stops every watcher at shutdown.

  * internal/scep/intune/trust_anchor_holder.go (Phase 8.5):
    TrustAnchorHolder mirrors cmd/server/tls.go::certHolder. RWMutex-
    guarded pool + Reload that swaps a fresh slice on success +
    WatchSIGHUP goroutine that responds to the same SIGHUP the existing
    TLS-cert watcher uses. A bad reload (parse error, expired cert)
    keeps the OLD pool in place so a half-rotation doesn't take Intune
    enrollment down — same fail-safe pattern. Operators rotate via the
    on-disk file then 'kill -HUP <certctl-pid>'.

  * internal/scep/intune/rate_limit.go (Phase 8.6): hand-rolled
    sliding-window-log limiter keyed by (Subject, Issuer). 100k-entry
    map cap (matches replay cache); at-cap drops the bucket whose
    newest timestamp is the oldest. Default 3 enrollments per 24h
    covers legitimate first-cert + recovery + post-wipe re-enrollment
    but blocks bulk enumeration from a compromised Connector signing
    key. maxN <= 0 disables the limiter for tests + the rare operator
    who wants no per-device cap. Empty subject short-circuits to allow
    (defense-in-depth: caller's claim validation rejects empty-subject
    upstream; no shared bucket on '').

    Why hand-rolled instead of golang.org/x/time/rate: the rate
    package is in go.sum as an indirect transitive but not a direct
    dep. ~30 LoC of stdlib avoids creating a new direct dep.

  * internal/service/scep.go (Phase 8.3 + 8.4 + 8.7):
    - SCEPService gains intuneEnabled / intuneTrust / intuneAudience /
      intuneValidity / intuneReplayCache / intuneRateLimiter /
      complianceCheck fields.
    - SetIntuneIntegration() constructor-time injection wires the
      per-profile state. Profiles with INTUNE_ENABLED=false never
      call this method, so they pay zero overhead.
    - SetComplianceCheck() installs the V3-Pro plug-in (see Phase 8.7).
    - looksIntuneShaped(): JWT-shape pre-check (length > 200 + exactly
      two dots). Allowed to false-positive (validator catches malformed
      → ErrChallengeMalformed); MUST NOT false-negative on real Intune
      challenges.
    - dispatchIntuneChallenge(): the load-bearing core. Runs
      ValidateChallenge → CSR-binding via DeviceMatchesCSR → replay
      cache CheckAndInsert → per-device Allow → optional ComplianceCheck.
      Each failure leg increments a typed metric label and emits an
      audit-friendly Warn log line.
    - PKCSReq + PKCSReqWithEnvelope + RenewalReqWithEnvelope all call
      dispatchIntuneChallenge first; on outcome.decided=true they
      either short-circuit (with a typed-error → SCEPFailInfo mapping)
      or call processEnrollment with action='scep_pkcsreq_intune'
      (so audit greps can count Intune-vs-static enrollments).
    - mapIntuneErrorToFailInfo(): typed-error → SCEPFailInfo per
      RFC 8894 §3.2.1.4.5 (signature/replay/expired → BadMessageCheck;
      claim-mismatch → BadRequest; default → BadRequest).
    - intuneFailReason(): typed-error → metric label
      ('signature_invalid' / 'expired' / 'rate_limited' / etc.). Default
      'malformed' so a previously-unseen error category still surfaces
      in the metric for follow-up.
    - ComplianceCheck (Phase 8.7): nil-default no-op gate. V3-Pro plugs
      in via SetComplianceCheck to call Microsoft Graph's compliance
      API. Returns (compliant, reason, err). nil-err + compliant=false
      → CertRep FAILURE + 'compliance' reason in audit. err != nil →
      fail-safe deny (V3-Pro module is responsible for any 'permit on
      API failure' policy).

  * internal/service/scep.go also gains parseCSRForIntune() — small
    private wrapper around encoding/pem + x509 used by the dispatcher
    for the claim ↔ CSR binding check (separated from the broader
    processEnrollment because we want to bind BEFORE consuming the
    replay-cache slot).

Tests (gates: ≥85% coverage on intune package, ≥70% on service):

  * scep_intune_test.go (in internal/service): 14 dispatcher tests
    covering happy-path Intune enrollment + static-challenge fallback
    + tampered-challenge reject + claim-mismatch reject + replay
    detected + rate-limited + compliance-hook nil-default + compliance-
    hook denies non-compliant + compliance-hook error fails closed +
    IntuneEnabled accessor + 'no IntuneEnabled = static path
    unchanged' regression pin + intuneFailReason mapping for every
    typed error + looksIntuneShaped boundary cases.

  * trust_anchor_holder_test.go (in internal/scep/intune): NewLoadsBundle,
    NewRequiresLogger, NewSurfacesLoadError, ReloadHappyPath,
    ReloadKeepsOldOnFailure, ReloadKeepsOldOnExpired (the fail-safe
    semantics that make the SIGHUP path operator-friendly),
    WatchSIGHUPReloadsPool (real SIGHUP to self with poll-for-swap
    pattern mirroring cmd/server/tls_test.go), WatchSIGHUPStopIsClean
    (does NOT fire SIGHUP after stop — same caveat as the TLS test:
    the Go runtime would otherwise terminate the test runner on the
    next SIGHUP since signal.Stop has removed the handler).

  * rate_limit_test.go (in internal/scep/intune): AllowsUpToCap,
    DistinctKeysIndependent, WindowExpiry, DisabledBypass (maxN=0),
    NegativeCapDisabled, EmptySubjectShortCircuits (defense-in-depth
    against an empty-subject DoS chokepoint), DefaultCapsHonored,
    MapCapEvictsOldest (at-cap eviction branch), ConcurrentRaceFree
    (50 goroutines × 200 inserts), pruneOlderThan + the no-op case.

Verification:

  * gofmt -l on all touched files: clean
  * go vet ./... : clean
  * staticcheck on intune/service/config/cmd-server: clean
  * go test -count=1 -cover ./internal/scep/intune/...: 94.8%
    (target ≥85%)
  * go test -short across intune+service+config+handler+cmd-server:
    all green
  * G-3 docs-drift CI guard reproduced locally: docs-only filtered=

shankar0123 a12a437664 feat(scep): mTLS sibling route /scep-mtls/<pathID> (opt-in)
SCEP RFC 8894 + Intune master bundle — Phase 6.5 of 14 (opt-in,
enterprise-procurement-checkbox).

Closes the procurement-team objection that 'shared password
authentication' is a checkbox-fail regardless of how strong the
password is. The clean answer: a sibling route that adds client-cert
auth at the handler layer AND keeps the challenge password (defense in
depth, not replacement). Devices present a bootstrap cert from a
trusted CA (e.g. a manufacturing-time cert), then SCEP-enroll for
their long-lived cert. Same model Apple's MDM and Cisco's BRSKI use.

internal/config/config.go
  * SCEPProfileConfig gains MTLSEnabled bool + MTLSClientCATrustBundlePath
    string. Indexed env-var loader reads
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED +
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_CLIENT_CA_TRUST_BUNDLE_PATH.
  * Validate() refuses MTLSEnabled=true with empty bundle path —
    structural defense in depth ahead of the file-content preflight.

cmd/server/main.go
  * preflightSCEPMTLSTrustBundle: file existence + PEM parse + ≥1
    CERTIFICATE block + non-expired check. Returns the parsed
    *x509.CertPool ready to inject into the per-profile SCEPHandler.
    Failures os.Exit(1) with the offending PathID in the structured log.
  * SCEP startup loop walks each profile; when MTLSEnabled, runs
    preflight, builds the per-profile pool, contributes the bundle's
    certs to the union pool that backs the TLS-layer
    VerifyClientCertIfGiven, clones the SCEPHandler with
    SetMTLSTrustPool, and registers the parallel sibling route via
    apiRouter.RegisterSCEPMTLSHandlers.
  * Union pool published to outer scope as scepMTLSUnionPoolForTLS;
    passed to buildServerTLSConfigWithMTLS so the listener serves both
    /scep[/<pathID>] (no client cert) and /scep-mtls/<pathID>
    (cert required at handler layer) on the same socket.
  * Final-handler dispatch gains /scep-mtls + /scep-mtls/* prefix
    routing through the no-auth chain (auth boundary is the client
    cert + challenge password, NOT a Bearer token).

cmd/server/tls.go
  * New buildServerTLSConfigWithMTLS that wraps buildServerTLSConfig
    + sets ClientCAs + ClientAuth=VerifyClientCertIfGiven when a
    non-nil pool is passed. nil pool = identical TLS shape to the
    pre-Phase-6.5 builder (no behavior change for deploys without
    mTLS profiles).
  * Critical: VerifyClientCertIfGiven (NOT RequireAndVerifyClientCert)
    so a client that doesn't present a cert can still hit the standard
    /scep route. The per-profile gate at the handler layer enforces
    'cert required' on /scep-mtls/<pathID>.

internal/api/handler/scep.go
  * SCEPHandler gains mtlsTrustPool *x509.CertPool field +
    SetMTLSTrustPool method. Per-profile pool injected by
    cmd/server/main.go after preflight.
  * HandleSCEPMTLS wrapper: gates on r.TLS.PeerCertificates non-empty
    + per-profile cert.Verify against THIS profile's pool. Returns
    HTTP 401 for missing/untrusted cert (mTLS failure is auth, not
    authorization). Returns HTTP 500 if mtlsTrustPool is nil (deploy
    bug — the route shouldn't have been registered). On success
    delegates to HandleSCEP — defense in depth: mTLS is additive,
    NOT replacement; the standard SCEP code path including the
    challenge-password gate still executes.
  * Per-profile re-verification via cert.Verify(...) is critical:
    the TLS layer verified against the UNION pool, so a cert that
    chains to profile A's bundle would pass TLS even when targeting
    profile B. The handler-layer gate prevents cross-profile
    bleed-through.

internal/api/router/router.go
  * AuthExemptDispatchPrefixes gains '/scep-mtls' (auth boundary is
    client cert + challenge password, NOT Bearer token).
  * RegisterSCEPMTLSHandlers parallel to RegisterSCEPHandlers:
    empty PathID maps to /scep-mtls root; non-empty maps to
    /scep-mtls/<pathID>. Each handler in the map MUST have had
    SetMTLSTrustPool called.

internal/api/router/openapi_parity_test.go
  * SpecParityExceptions allowlists 'GET /scep-mtls' + 'POST
    /scep-mtls' since the wire format is identical to /scep —
    documenting both routes separately would duplicate every
    operation row with no information gain. Documented alternative
    in docs/legacy-est-scep.md.

internal/api/handler/scep_mtls_test.go (new, ~210 LoC)
  * 6 tests + 2 helpers covering the auth contract:
    1. RejectsMissingClientCert — request with r.TLS=nil → 401
    2. RejectsUntrustedClientCert — cert chains to a different
       CA → 401 (per-profile re-verification works)
    3. AcceptsTrustedClientCert — cert chains to THIS profile's
       pool → 200 (delegates to HandleSCEP)
    4. StillRoutesThroughHandleSCEP — pin Content-Type + body
       come from HandleSCEP delegate (defense in depth pin)
    5. NoTrustPool_Returns500 — handler with SetMTLSTrustPool
       never called → 500 (deploy-bug surface)
    6. StandardRoute_StillNoMTLS — pin /scep keeps working
       without a client cert even when mTLS pool is set
  * genSelfSignedECDSACA + signECDSAClientCert helpers materialise
    real cert chains (trusted-bootstrap-ca + trusted-device,
    untrusted-attacker-ca + untrusted-device) so the Verify path
    exercises real x509 chain validation, not mocks.

docs/features.md
  * SCEP env-vars table extended with the two new MTLS env vars
    (CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED,
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_CLIENT_CA_TRUST_BUNDLE_PATH).
    Closes the G-3 'env var defined in Go but never documented' gate.

docs/legacy-est-scep.md
  * New 'mTLS sibling route (Phase 6.5, opt-in)' section covering
    opt-in env vars, TLS server config (union pool +
    VerifyClientCertIfGiven), handler-layer per-profile gate,
    full auth chain on /scep-mtls/<pathID>, operator migration
    workflow from challenge-password-only to challenge+mTLS.

cowork/CLAUDE.md::Active Focus
  * 'HALF 1 COMPLETE' updated from '(Phases 0-5 of 14 SHIPPED)' to
    '(Phases 0-6 + Phase 6.5 of 14 SHIPPED)'.

Verification:
  * gofmt + go vet + staticcheck clean across api/handler /
    api/router / config / cmd/server.
  * go test -short -count=1 green across api/handler (with the new
    scep_mtls_test.go) / api/router / service / config / pkcs7 /
    cmd/server / connector/issuer/local.
  * G-3 docs-drift CI guard local check: empty in both directions
    after the new MTLS env vars landed in features.md.
  * The constitutional test ('can an operator flip the bit and
    observe the behavior change end-to-end?') is YES: setting
    CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED=true plus the trust
    bundle path produces a working /scep-mtls/<pathID> endpoint
    that accepts trusted client certs + rejects untrusted ones,
    with no further code changes required.

Phase 6.5 of 14 in SCEP RFC 8894 + Intune master bundle.
Half 1 (Phases 0-6 + 6.5) is now FEATURE-COMPLETE for the
ChromeOS / general-MDM use case. Half 2 (Phases 7-12) adds the
Microsoft Intune dynamic-challenge layer.

shankar0123 a546a1bbef feat(scep): EnvelopedData decrypt + signerInfo POPO verify (RFC 8894 §3.2)
SCEP RFC 8894 + Intune master bundle — Phase 2 of 14.

Implements the new RFC 8894 PKIMessage parse path: EnvelopedData parser
+ decryptor, signerInfo parser + signature verifier, handler dispatch
that tries the RFC 8894 path FIRST and falls through to the legacy MVP
raw-CSR path on any parse failure. Backward compat with lightweight SCEP
clients is preserved by design — no behavior change for any existing
deploy that doesn't set CERTCTL_SCEP_RA_*.

internal/pkcs7/envelopeddata.go (new, ~330 LoC)
  * ParseEnvelopedData: parses CMS EnvelopedData per RFC 5652 §6.1, with
    optional outer ContentInfo unwrapping. Handles SET OF RecipientInfo
    + IssuerAndSerial form rid (RFC 8894 §3.2.2).
  * EnvelopedData.Decrypt: RSA PKCS#1 v1.5 key-trans + AES-CBC (128/192/
    256) or DES-EDE3-CBC content decryption with **constant-time PKCS#7
    padding strip** (no branch on padding-byte values; closes the
    padding-oracle leak surface). Recipient mismatch is BadMessageCheck
    per RFC 8894 §3.3.2.2 (NOT BadCertID); every failure mode returns
    the same ErrEnvelopedDataDecrypt sentinel to close timing-leak legs
    of Bleichenbacher attacks.
  * Equivalent to micromdm/scep's cryptoutil/cryptoutil.go::DecryptPKCS-
    Envelope (cited in code comments; not vendored — fuzz-target
    ownership stays in this sub-package per the operating rule).

internal/pkcs7/signedinfo.go (new, ~370 LoC)
  * ParseSignedData / ParseSignerInfos: parses CMS SignedData per RFC
    5652 §5.3. Resolves each SignerInfo's SID (IssuerAndSerial v1 OR
    [0] SubjectKeyId v3) against the SignedData certificates SET to
    pluck the device's transient signing cert.
  * SignerInfo.VerifySignature: re-serialises signedAttrs as the
    canonical SET OF Attribute (the RFC 5652 §5.4 quirk every CMS
    implementation hits — wire form is [0] IMPLICIT but the signature
    is over EXPLICIT SET OF). Hashes with SHA-1/SHA-256/SHA-512 +
    verifies via RSA PKCS1v15 or ECDSA per the cert's pubkey type.
  * Auth-attr extractors: GetMessageType (PrintableString-decimal),
    GetTransactionID, GetSenderNonce, GetMessageDigest. SCEP attr OIDs
    pinned (RFC 8894 §3.2.1.4).

internal/pkcs7/{envelopeddata,signedinfo}_fuzz_test.go (new)
  * FuzzParseEnvelopedData / FuzzParseSignedData / FuzzParseSignerInfos
    / FuzzVerifySignerInfoSignature — every parser certctl adds gets a
    panic-safety fuzzer (the fuzz-target-ownership rule from
    cowork/CLAUDE.md::Operating Rules). Local 5s runs hit ~270k
    executions per parser without panic. Errors are expected for
    arbitrary inputs; only panics are bugs.

internal/pkcs7/{envelopeddata,signedinfo}_test.go (new)
  * Round-trip tests that materialise real RSA/ECDSA pairs, hand-build
    the wire bytes, parse + decrypt + verify, and assert plaintext /
    auth-attr equality. The build helpers use this package's ASN1Wrap
    primitives directly (asn1.Marshal of structs containing nested
    asn1.RawValue is finicky for mixed Class/Tag); gives byte-level
    control matching what real SCEP clients emit.
  * Negative tests: tampered ciphertext / tampered auth-attrs / wrong
    RA / wrong key / mismatched recipients / random garbage all return
    the appropriate sentinel error without panic.

internal/service/scep.go
  * PKCSReqWithEnvelope: RFC 8894 envelope-aware variant. Returns
    *SCEPResponseEnvelope (not error + *SCEPEnrollResult) because RFC
    8894 §3.3 mandates a CertRep PKIMessage on every response, even
    failures — the handler shouldn't translate Go errors into SCEP
    failInfo codes. Returns nil to signal 'invalid challenge password'
    so the caller can translate to HTTP 403 (matches MVP path's wire
    shape; RFC 8894 §3.3.1 is silent on this case).
  * mapServiceErrorToFailInfo: exact mapping table from the prompt
    (CSR parse → BadRequest, CSR sig → BadMessageCheck, crypto policy
    → BadAlg, default → BadRequest).

internal/api/handler/scep.go
  * SCEPService interface gains PKCSReqWithEnvelope.
  * SCEPHandler now optionally carries an RA cert + key pair. SetRAPair
    upgrades the handler to the RFC 8894 path; without that call the
    handler stays MVP-only (the v2.0.x behavior).
  * pkiOperation: tries the RFC 8894 path FIRST when the RA pair is
    set. tryParseRFC8894 helper does the full pipeline (ParseSignedData
    → VerifySignature → extract auth-attrs → ParseEnvelopedData → Decrypt
    → x509.ParseCertificateRequest the recovered bytes). On any failure
    it falls through to the legacy extractCSRFromPKCS7 MVP path —
    backward compat is non-negotiable.
  * Phase 2 emits the legacy certs-only response on RFC 8894 success;
    Phase 3 (next commit) swaps in writeCertRepPKIMessage with the
    proper status / failInfo / nonce-echo wire shape.

cmd/server/main.go
  * Per-profile loop now calls loadSCEPRAPair after preflight to load
    the cert + key + inject via SetRAPair. crypto + crypto/tls imports
    added.
  * loadSCEPRAPair helper: tls.X509KeyPair-based parse + leaf cert
    extraction. Failures here indicate TOCTOU between preflight + load.

internal/api/handler/scep_handler_test.go +
internal/api/router/router_scep_profiles_test.go
  * mockSCEPService / scepProfileMockService gain PKCSReqWithEnvelope
    stubs to satisfy the extended interface. Existing test cases
    unchanged (they exercise the MVP path; RA pair is unset).

Verification:
  * gofmt + go vet clean for the files I touched.
  * go test -short -count=1 green across pkcs7 / api/handler /
    api/router / service / cmd/server.
  * Coverage: pkcs7 78.4% (was 100% — drops because new code includes
    paths the round-trip tests don't yet hit, like decryption alg
    fall-through and v3 SubjectKeyId SID matching).
  * Fuzz-target seed-corpus runs (5s each, ~270k execs/parser): no
    panic. Pre-merge fuzz-time bumps to 30s per the prompt's
    verification gate.

shankar0123 fdd424bf5f feat(scep): per-issuer SCEP profiles — multi-endpoint dispatch
SCEP RFC 8894 + Intune master bundle — Phase 1.5 of 14.

Restructures SCEPConfig from a single flat struct (one IssuerID + one
RA pair + one challenge password) to a Profiles slice where each
profile binds its own URL path (/scep/<pathID>), issuer, optional
CertificateProfile, RA cert+key, and challenge password.

This phase is the FOUNDATION for Phases 2-12: every downstream handler
signature, service envelope, CertRep builder, GUI counter, and test
fixture takes a profile_id parameter from here on. Adding multi-profile
support post-bundle would cost 3x what greenfielding it now does.

Backward compat: legacy CERTCTL_SCEP_* flat env vars synthesise a
single-element Profiles[0] with PathID="" (legacy /scep root) when
CERTCTL_SCEP_PROFILES is unset. Existing operators see no behavior
change. New operators write multi-profile config directly via the
indexed env-var form.

Indexed env-var convention:
  CERTCTL_SCEP_PROFILES=corp,iot,server
  CERTCTL_SCEP_PROFILE_CORP_ISSUER_ID=iss-corp-laptop
  CERTCTL_SCEP_PROFILE_CORP_PROFILE_ID=prof-corp-tls
  CERTCTL_SCEP_PROFILE_CORP_CHALLENGE_PASSWORD=...
  CERTCTL_SCEP_PROFILE_CORP_RA_CERT_PATH=/etc/certctl/scep/corp-ra.crt
  CERTCTL_SCEP_PROFILE_CORP_RA_KEY_PATH=/etc/certctl/scep/corp-ra.key
  ... (etc per profile name)

internal/config/config.go
  * SCEPConfig.Profiles []SCEPProfileConfig — primary multi-profile
    dispatch source.
  * Legacy flat fields (IssuerID, ProfileID, ChallengePassword,
    RACertPath, RAKeyPath) preserved with updated docblocks marking
    them as merge sources for the backward-compat shim.
  * SCEPProfileConfig new struct (PathID, IssuerID, ProfileID,
    ChallengePassword, RACertPath, RAKeyPath).
  * loadSCEPProfilesFromEnv: reads CERTCTL_SCEP_PROFILES (comma-list
    of names), expands each to per-profile env vars
    CERTCTL_SCEP_PROFILE_<NAME>_*. Returns nil when unset so the
    legacy-shim path takes over.
  * mergeSCEPLegacyIntoProfiles: when SCEP enabled + Profiles empty +
    any legacy flat field populated, synthesises Profiles[0] with
    PathID="". No-op when Profiles already populated (structured form
    wins) or SCEP disabled.
  * validSCEPPathID: empty allowed (legacy /scep root); non-empty
    must be [a-z0-9-] with no leading/trailing hyphen.
  * Per-profile Validate gates: PathID format, uniqueness across the
    slice, ChallengePassword presence (CWE-306 per profile), RA pair
    presence (RFC 8894 §3.2.2), IssuerID presence.
  * Legacy single-profile gates skip when Profiles is non-empty so
    the per-profile loop owns the gating in the structured case
    (avoids double-fire with overlapping error messages).

internal/api/router/router.go
  * RegisterSCEPHandlers signature: map[string]handler.SCEPHandler
    (was a single SCEPHandler).
  * Empty PathID handler registered with literal r.Register('GET /scep'
    + 'POST /scep') so the openapi-parity AST scanner (Bundle D /
    Audit M-027) continues to see the documented /scep route. Without
    this preservation, the parity test fails because dynamic
    string-built routes don't appear in *ast.BasicLit walks.
  * Non-empty PathIDs registered dynamically as /scep/<pathID>.
  * AuthExempt prefix /scep already covers all /scep[/...] paths via
    prefix match — no change needed there.

cmd/server/main.go
  * SCEP startup block iterates cfg.SCEP.Profiles, builds one service
    + one handler per profile, stuffs them into a {pathID -> handler}
    map, hands the map to apiRouter.RegisterSCEPHandlers.
  * Per-profile preflight: preflightSCEPChallengePassword,
    preflightSCEPRACertKey, preflightEnrollmentIssuer fire ONCE PER
    PROFILE with a profile-scoped slog.Logger so failures report
    PathID + IssuerID. Each per-profile failure os.Exits(1) with a
    targeted error message.
  * Final 'SCEP server enabled' info log reports profile_count.

internal/config/config_scep_profiles_test.go (new, 9 tests / 22 sub-cases)
  * TestSCEPConfig_LegacyFlatFields_SynthesizeSingleProfile — the
    backward-compat smoke test.
  * TestSCEPConfig_MultipleProfiles_LoadFromEnv — structured-form
    happy path with two profiles.
  * TestSCEPConfig_StructuredFormBeatsLegacy — when both forms set,
    structured wins; legacy flat field MUST NOT leak into
    Profiles[0].ChallengePassword.
  * TestSCEPConfig_PathIDValidation — 13 sub-cases covering valid +
    every reject mode (uppercase, slash, leading/trailing hyphen,
    underscore, dot, space, non-ASCII).
  * TestSCEPConfig_DuplicatePathID_Refuses.
  * TestSCEPConfig_MissingPerProfileChallengePassword,
    _MissingPerProfileRAPair (3 sub-cases),
    _MissingPerProfileIssuerID — per-profile gate triplet.
  * TestSCEPConfig_DisabledIgnoresProfiles — gates only fire when
    SCEP is enabled.

internal/api/router/router_scep_profiles_test.go (new, 4 tests)
  * TestRouter_RegisterSCEPHandlers_LegacyEmptyPathIDMapsToRoot —
    empty PathID gets /scep root; both GET + POST routes registered.
  * TestRouter_RegisterSCEPHandlers_NonEmptyPathIDMapsToSubpath —
    non-empty PathID gets /scep/<pathID>; /scep root NOT registered
    when no empty-PathID profile exists.
  * TestRouter_RegisterSCEPHandlers_MultipleProfilesNoCrossBleed —
    three profiles (default, corp, iot); each path reaches the right
    handler instance, verified via per-profile-tagged GetCACaps mock
    response.
  * TestRouter_RegisterSCEPHandlers_EmptyMapRegistersNoRoutes — no
    profiles → no /scep routes (deploy with SCEP disabled).

Verification:
  * gofmt clean for the files I touched.
  * go vet clean across config / router / cmd/server / domain.
  * go test -short -count=1 green across config / router / cmd/server /
    api/handler / service / domain / pkcs7.
  * Coverage held: handler 79.0% / service 73.2% / pkcs7 100% /
    config 96.0% / domain 88.6% / router 100% / cmd/server 19.2%.
  * openapi-parity test green (literal /scep registrations preserved).

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.
Living progress at cowork/scep-rfc8894-intune/progress.md.

shankar0123 a4df1f86ae crl/ocsp: admin observability endpoint + Phase 6 e2e scaffold
Phase 5 (admin endpoint slice) + Phase 6 (e2e test stub) of the
CRL/OCSP responder bundle. Closes the deferred items from the
backend-slice merge (77d6326).

What landed:

  Phase 5 — admin observability:
  * GET /api/v1/admin/crl/cache (handler.AdminCRLCacheHandler):
    - Per-issuer cache state + most recent N generation events
    - Admin-gated via middleware.IsAdmin (M-003 pattern); non-admin
      callers get 403 + the service is never invoked
    - Reveals issuer set + CRL cadence, hence the gate
    - Returns CachePresent=false rows for never-generated issuers so
      the GUI can show 'not yet generated' instead of 404
    - Per-issuer Get failures decorate the row's RecentEvents rather
      than failing the whole response
  * AdminCRLCacheServiceImpl: thin handler-side composition over
    repository.CRLCacheRepository + an issuer-IDs callback (avoids
    importing internal/service from internal/api/handler)
  * M-008 admin-gate pin updated: admin_crl_cache.go added to
    AdminGatedHandlers; full triplet of tests
    (NonAdmin_Returns403, AdminExplicitFalse_Returns403,
    AdminPermitted_ForwardsActor) + RejectsNonGetMethod +
    PropagatesServiceError
  * Router registration + HandlerRegistry field + main.go wiring
    (callback closure over issuerRegistry.List)
  * OpenAPI entry under CRL & OCSP tag

  Phase 6 — e2e scaffold:
  * deploy/test/crl_ocsp_e2e_test.go with TestCRLOCSPLifecycle +
    TestCRLOCSPPostEndpoint
  * Lifecycle test exercises issue → fetch OCSP (Good) → revoke →
    wait → fetch CRL (entry present) → fetch OCSP (Revoked) →
    verify dedicated responder cert + id-pkix-ocsp-nocheck
  * Helpers (issueLocalCert, revokeCertViaAPI, fetchCRL, fetchOCSP,
    fetchCACert) currently call t.Skip with TODO markers — sandbox
    has no Docker so the harness can't be wired end-to-end here;
    when CI / a fresh dev workstation runs, the implementer wires
    each helper to the existing integration_test.go primitives
  * Build-tagged //go:build integration so the standard go test
    sweep skips it; runs via the deploy/test integration workflow

Coverage: handler 80.6% (above 75 floor; was 79.8% pre-Phase-5).
All other packages unchanged.

Backward compat: admin endpoint inert until an admin Bearer key is
configured. The e2e test stub is no-op (skips) until wired.

Deferred:
  * GUI cert-detail-page revocation panel — pure frontend work, no
    backend impact, separate session
  * E2E test helper wiring — depends on extracting the existing
    integration-test harness primitives into shared helpers; doable
    in a follow-up that has Docker available
  * V3-Pro polish (delta CRLs, OCSP rate-limiting, OCSP stapling)

shankar0123 db71b47c24 main: wire CRL/OCSP responder services into runtime
Activates the CRL/OCSP responder pipeline that landed dormant in
phases 1-4 (commits 30765ba, a0b7f7d, dc32694, dc1e0bf):

  * IssuerRegistry gains SetLocalIssuerDeps + LocalIssuerDeps struct.
    Rebuild type-asserts each constructed connector to *local.Connector
    and injects ocspResponderRepo + signerDriver + IssuerID + key dir
    + (optional) rotation-grace + validity overrides. Non-local
    connectors are unaffected (the type-assert fails silently). Adapter
    pattern preserved: callers still see service.IssuerConnector.

  * cmd/server/main.go:
    - constructs CRLCacheRepository + OCSPResponderRepository from db
    - constructs signer.FileDriver (default; PKCS#11 driver plugs in
      later via the same Driver interface, no main.go changes needed)
    - calls issuerRegistry.SetLocalIssuerDeps(...) BEFORE BuildRegistry
      so the deps are in place when local connectors are constructed
    - wires CRLCacheService into CertificateService via SetCRLCacheSvc
      (Phase 4 cache-aware GenerateDERCRL path now active)
    - calls scheduler.SetCRLCacheService + SetCRLGenerationInterval
      after sched is constructed; logs the interval at startup

  * config: new OCSPResponderConfig struct + Scheduler.CRLGenerationInterval
    field. Three new env vars:
      CERTCTL_OCSP_RESPONDER_KEY_DIR (no default; operator MUST set in prod)
      CERTCTL_OCSP_RESPONDER_ROTATION_GRACE (default 7d)
      CERTCTL_OCSP_RESPONDER_VALIDITY (default 30d)
      CERTCTL_CRL_GENERATION_INTERVAL (default 1h)

Backward compat: when env vars are unset, the responder bootstrap path
still activates (with default rotation grace + validity, key dir = cwd
which is fine for tests), and the CRL cache pre-populates on the
1h interval. Operators not running the local issuer see no behavior
change.

go vet clean across the full module. Targeted tests for config +
service + scheduler packages all green. Full module build deferred
to CI (sandbox /sessions disk pressure prevented unzipping a
transitive dep — same disk-full pattern the prior commits hit; not
a code issue).

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.

Closes M-001 + M-002 + M-013 + M-018 + M-025 from
comprehensive-audit-2026-04-25.

M-001 (CWE-916) — PBKDF2 100k -> 600k via v3 blob format
  internal/crypto/encryption.go:
    - New v3Magic (0x03), pbkdf2IterationsV3 (600,000 — OWASP 2024
      Password Storage Cheat Sheet floor), v3SaltSize (16 bytes),
      deriveKeyWithSaltV3 helper.
    - EncryptIfKeySet now unconditionally writes v3:
        magic(0x03) || salt(16) || nonce(12) || ciphertext+tag
    - DecryptIfKeySet falls through v3 -> v2 -> v1 with AEAD verification
      at each step. Wrong-passphrase v3 reads cannot be silently
      misattributed to v2/v1.
    - IsLegacyFormat updated to recognize 0x03 as non-legacy.
  internal/crypto/encryption_v3_test.go (NEW, 7 tests):
    V3 round-trip / V2 read-fallback against deterministic v2 fixture /
    V3 wrong-passphrase fails / V3-vs-V2 dispatch order / V2 vs V3 keys
    differ for same (passphrase, salt) / iteration-count pin at OWASP
    2024 floor / IsLegacyFormat-recognises-V3.
  Coverage internal/crypto: 86.7% -> 88.2%.

M-002 (CWE-862) — Auth-exempt allowlist constants + AST regression test
  Recon found auth-exempt surface spans TWO layers (audit's claim was
  incomplete):
    Layer 1 (router.go direct r.mux.Handle):
      GET /health, GET /ready, GET /api/v1/auth/info, GET /api/v1/version
    Layer 2 (cmd/server/main.go::buildFinalHandler URL-prefix dispatch):
      /.well-known/pki/*, /.well-known/est/*, /scep[/...]*
  internal/api/router/router.go:
    - New AuthExemptRouterRoutes constant with per-entry justifications.
    - New AuthExemptDispatchPrefixes constant.
  internal/api/router/auth_exempt_test.go (NEW, 2 tests):
    AST-walks router.go for every direct mux.Handle call and asserts
    set equals AuthExemptRouterRoutes; reads source bytes of Register /
    RegisterFunc and asserts they still wrap with middleware.Chain.
  cmd/server/auth_exempt_test.go (NEW, 2 tests):
    14-case table test on buildFinalHandler asserting documented
    prefixes route to noAuthHandler and authenticated routes route to
    apiHandler; inverse-overlap pin proves no documented bypass shadows
    an authenticated prefix.

M-013 (CWE-942) — CORS deny-by-default verified-already-clean + pin
  Audit claim 'default allows all origins if env-var unset' was WRONG.
  internal/api/middleware/middleware.go::NewCORS already denies cross-
  origin requests when len(cfg.AllowedOrigins) == 0 (no
  Access-Control-Allow-Origin header is emitted, same-origin policy
  applies).
  internal/api/middleware/cors_test.go: +TestNewCORS_NilOriginsDeniesAll
  + TestNewCORS_M013_ContractDocumentedInOrder (5-case table test
  pinning the 3-arm dispatch contract).

M-018 (CWE-319 / PCI-DSS Req 4) — Postgres TLS opt-in toggle
  deploy/helm/certctl/values.yaml: new postgresql.tls.{mode,caSecretRef}
    operator-facing knobs. Default 'disable' preserves in-cluster pod-
    network behavior; PCI-scoped operators set verify-full.
  deploy/helm/certctl/templates/_helpers.tpl: certctl.databaseURL helper
    pipes postgresql.tls.mode into ?sslmode=.
  deploy/helm/certctl/templates/server-secret.yaml: uses the helper
    instead of hardcoded sslmode=disable.
  deploy/docker-compose.yml: CERTCTL_DATABASE_URL is now
    ${CERTCTL_DATABASE_URL:-...} so operators override without editing.
  docs/database-tls.md (NEW): operator runbook covering 4 deployment
    shapes, RDS verify-full example with PGSSLROOTCERT mount, and
    pg_stat_ssl verification query.
  helm template + helm lint clean.

M-025 (OWASP ASVS L2 §11.2.1) — Per-key rate limiting
  internal/api/middleware/middleware.go::NewRateLimiter rewritten from
  a single global tokenBucket to a keyedRateLimiter map keyed on
    'user:'+GetUser(ctx)  for authenticated callers
    'ip:'+RemoteAddr-host for unauthenticated
  - Empty UserKey strings treated as unauthenticated.
  - X-Forwarded-For intentionally NOT consulted (header-spoofing risk).
  - Create-on-demand bucket allocation under sync.RWMutex with double-
    check pattern.
  RateLimitConfig.PerUserRPS / PerUserBurstSize fields with env vars
    CERTCTL_RATE_LIMIT_PER_USER_RPS / CERTCTL_RATE_LIMIT_PER_USER_BURST
    allow per-user budgets distinct from per-IP.

shankar0123 85e60b24ec fix(bundle-5): Operational Liveness + Bootstrap — 4 audit findings closed
Closes Audit-2026-04-25 H-006 (High), H-007 (High), M-011 (Medium),
L-006 (Low — verified-already-closed via C-1 master closure in v2.0.54).
Hardens the orchestrator-facing surface — k8s probes, agent enrollment,
shutdown audit drain, scheduler config plumbing.

What changed
- internal/api/handler/health.go — split contract:
    * /health stays shallow 200 (k8s liveness — process alive)
    * /ready accepts *sql.DB; runs db.PingContext(2s); 503 on failure
    * Nil DB path returns 200 + db=not_configured (test fixtures)
- internal/api/handler/agent_bootstrap.go (NEW) — verifyBootstrapToken:
    * empty expected = warn-mode pass-through
    * non-empty = `Authorization: Bearer <token>` required
    * crypto/subtle.ConstantTimeCompare; length-mismatch path runs dummy
      compare to keep timing uniform
    * ErrBootstrapTokenInvalid sentinel
- internal/api/handler/agents.go — RegisterAgent calls verifyBootstrapToken
  BEFORE body parse so unauth probes don't even allocate a JSON decoder
- internal/config/config.go — two new env vars:
    * CERTCTL_AGENT_BOOTSTRAP_TOKEN  (Auth.AgentBootstrapToken)
    * CERTCTL_AUDIT_FLUSH_TIMEOUT_SECONDS (Server.AuditFlushTimeoutSeconds)
- cmd/server/main.go — 3 changes:
    * pass *sql.DB into NewHealthHandler (H-006)
    * pass cfg.Auth.AgentBootstrapToken into NewAgentHandler (H-007)
    * configurable shutdown audit-flush timeout (M-011)
    * one-shot startup WARN when bootstrap token unset (deprecation)
- new tests: agent_bootstrap_test.go (full deny/accept/warn-mode coverage,
  constant-time compare path, length-mismatch); health_test.go extended
  with /ready DB-probe failure (503), nil-DB pass-through, /health-shallow

L-006 verified
- cmd/server/main.go:557 already calls
  sched.SetShortLivedExpiryCheckInterval(cfg.Scheduler.ShortLivedExpiryCheckInterval)
  per the C-1 master closure in v2.0.54. Bundle 5 confirms; no code change.

Threat model: TB-1 (operator/orchestrator), TB-2 (Agent↔Server).
- CWE-754 (Improper Check for Unusual or Exceptional Conditions) for H-006
- CWE-306 + CWE-288 (Missing Authentication for Critical Function) for H-007

Verification
- go vet ./...                               → clean
- go build ./...                             → clean
- go test -short -count=1 ./...              → all packages pass
- targeted Bundle-5 regressions               → all pass
- npx tsc --noEmit (web)                     → clean
- npx vitest run (web)                       → in-flight (sandbox 45s
  ceiling exceeded; no failure markers in dot stream; no frontend
  changes in this bundle so no regression risk)
- python3 yaml.safe_load(api/openapi.yaml)   → 89 paths

Backward compatibility
- Bootstrap token defaults to empty (warn-mode) — existing demo
  deployments unaffected. Server logs deprecation WARN; v2.2.0 will
  require it.
- Audit flush timeout default 30s preserves prior behaviour.
- Helm chart already routes readiness probe to /ready (no chart change
  needed); now /ready actually probes the DB.

2026-04-25 23:54:18 +00:00
shankar0123 1c099071d1 fix(bundle-4): EST/SCEP Attack Surface Hardening — 3 audit findings closed
Closes 3 findings (1 High + 1 Medium + 1 Low) from
/Users/shankar/Desktop/cowork/comprehensive-audit-2026-04-25/.

Bundle 4 hardens the only attack surface reachable by an anonymous network
attacker in certctl: the unauthenticated EST + SCEP enrollment endpoints.

Findings closed:

  - H-004 (High): Hand-rolled ASN.1 parser had no fuzz target.
    The audit's original framing pointed at internal/pkcs7/, but recon
    confirmed that package is an ASN.1 ENCODER (BuildCertsOnlyPKCS7,
    ASN1Wrap*, ASN1EncodeLength) — not a parser. The actual hand-rolled
    PKCS#7 PARSING reachable via anonymous network is in
    internal/api/handler/scep.go::extractCSRFromPKCS7 +
    parseSignedDataForCSR. Added native go fuzz targets:
      * internal/api/handler/scep_fuzz_test.go::FuzzExtractCSRFromPKCS7
      * internal/api/handler/scep_fuzz_test.go::FuzzParseSignedDataForCSR
      * internal/pkcs7/pkcs7_fuzz_test.go::FuzzPEMToDERChain (defense-in-depth)
      * internal/pkcs7/pkcs7_fuzz_test.go::FuzzASN1EncodeLength (defense-in-depth)
    Local 15s fuzz session: 150k execs on FuzzExtractCSRFromPKCS7,
    937k on FuzzPEMToDERChain, 925k on FuzzASN1EncodeLength — zero panics.

  - M-021 (Medium): EST TLS-Unique channel binding (RFC 7030 §3.2.3).
    Added internal/api/handler/est.go::verifyESTTransport — defense-in-depth
    TLS pre-conditions (r.TLS != nil; HandshakeComplete; TLS ≥ 1.2).
    The full §3.2.3 channel binding only applies when EST mTLS is in use;
    certctl does not currently support EST mTLS, so the §3.2.3 requirement
    is moot today. RFC 9266 (TLS 1.3 tls-exporter) and EST mTLS are
    documented as deferred follow-ups in the verifyESTTransport doc comment.

  - L-005 (Low): EST/SCEP issuer-binding fail-loud at startup.
    Pre-Bundle-4 cmd/server/main.go validated that CERTCTL_EST_ISSUER_ID and
    CERTCTL_SCEP_ISSUER_ID existed in the registry but did NOT validate the
    issuer TYPE could emit a CA cert. An operator binding EST to an ACME
    issuer (whose GetCACertPEM returns explicit error) booted successfully
    and only failed at first /est/cacerts request. Post-Bundle-4: new
    preflightEnrollmentIssuer helper calls GetCACertPEM(ctx) at startup
    with a 10s timeout. Failure logs the connector error + the candidate
    issuer types and os.Exit(1).

Tests added/modified:
  - internal/api/handler/est_transport_test.go (new) — 5 verifyESTTransport
    table cases covering plaintext-rejected, incomplete-handshake-rejected,
    TLS 1.0 rejected, TLS 1.2/1.3 accepted
  - cmd/server/preflight_test.go (new) — TestPreflightEnrollmentIssuer
    covering nil-connector, error-from-issuer, empty-PEM, valid cases
  - internal/api/handler/est_handler_test.go (modified) — 7 POST sites
    now stamp r.TLS to satisfy the new transport pre-condition
  - internal/integration/negative_test.go (modified) — setupTestServer
    wraps the test handler with a fake-TLS-state injector so the EST
    handler receives r.TLS != nil; production paths still rely on the
    real TLS listener

shankar0123 1c6009a920 chore(cleanup,docs): vite proxy + dead scheduler setter wired + registerAgent/CLI docs (C-1 master)
Closes six 2026-04-24 audit findings (3 P2 + 3 P3) — a cleanup-and-doc
tail bundle that drains the smallest remaining leaves of the audit:

  - cat-u-vite_dev_proxy_plaintext_drift (P2): web/vite.config.ts
    proxied dev requests to http://localhost:8443 against an HTTPS-only
    backend (HTTPS-only since v2.0.47). Every dev-server API call 502'd.
    Fix: targets are now object-form `{target: 'https://...', secure: false,
    changeOrigin: true}` — the dev cert is self-signed by the
    deploy/test bootstrap and changes per-checkout.

  - cat-g-7e38f9708e20 (P3): Scheduler.SetShortLivedExpiryCheckInterval
    was defined + tested but never called from cmd/server/main.go.
    Operators tuning CERTCTL_SHORT_LIVED_EXPIRY_CHECK_INTERVAL got
    no effect — the 30s default in scheduler.NewScheduler was
    effectively hardcoded. Fix: added Config.Scheduler.ShortLivedExpiryCheckInterval
    + getEnvDuration in Load() reading the env var with a 30s default,
    + sched.SetShortLivedExpiryCheckInterval(...) call in main.go
    alongside the other scheduler-interval setters.

  - diff-10xmain-2bf4a0a60388 (P3): same root cause as cat-g-7e38f9708e20;
    closes as ride-along.

  - cat-b-6177f36636fb (P2): registerAgent client fn orphan. By-design
    per pull-only deployment model. Fix (audit recommendation:
    "document"): added a closure docblock above the export in
    client.ts + a new "Registration is by-design pull-only" paragraph
    in docs/architecture.md::Agents section explaining when/why a
    future GUI-driven enrollment feature might reach the endpoint
    (proxy-agent topologies for network appliances).

  - cat-i-7c8b28936e3d (P2): CLI scope intentionally narrow but
    undocumented. Fix: new "Scope (intentionally narrow)" subsection
    in docs/features.md::CLI capturing the SSH-into-prod / day-to-day
    GUI / AI-automation MCP three-way split.

Verification:
- go build ./... — clean
- go vet ./... — clean
- go test ./internal/scheduler/... ./internal/config/... — pass
- golangci-lint v2.11.4 run ./... — 0 issues
- tsc --noEmit (frontend) — clean
- All sibling guardrails (S-1 / G-3 / D-1+D-2 / B-1 / L-1 / H-1) still pass

Audit findings closed:
- cat-u-vite_dev_proxy_plaintext_drift (P2)
- cat-g-7e38f9708e20 (P3)

- cat-i-7c8b28936e3d (P2)
- (audit-bookkeeping ride-along: ensures every closed-bundle row has a non-empty merge SHA)

Deferred follow-ups: none from this bundle. The remaining audit
backlog (frontend test campaign, F-1 CertificatesPage UX, P-1
orphan-fn sweep, S-2 handler error-mapping refactor) is sibling
sub-bundles in this mega-prompt.

shankar0123 3e78ecb799 feat(security): bodyLimit on noAuth + security headers + encryption-key validation (H-1 master)
Closes three 2026-04-24 audit findings (all P2):
  - cat-s5-4936a1cf0118: noAuthHandler chain accepted arbitrary-size
    bodies (EST simpleenroll, SCEP, PKI CRL/OCSP, /health, /ready).
    Memory exhaustion vector without HTTP-layer auth gatekeeping.
  - cat-s11-missing_security_headers: zero security headers on any
    response. Clickjacking, MIME-sniffing, untrusted-origin resource
    loads against the dashboard and API.
  - cat-r-encryption_key_no_length_validation: CERTCTL_CONFIG_ENCRYPTION_KEY
    accepted with any non-empty value including a single character.
    PBKDF2-SHA256 (100k rounds) does not compensate for low-entropy
    passphrases at scale (CWE-916, CWE-329).

Changes:
- cmd/server/main.go::noAuthHandler chain — added bodyLimitMiddleware
  + securityHeadersMiddleware. Same default cap as authed surface
  (1MB via CERTCTL_MAX_BODY_SIZE), same 413 on overflow.
- cmd/server/main.go::middlewareStack (authed) — added
  securityHeadersMiddleware before corsMiddleware.
- internal/api/middleware/securityheaders.go (new) — SecurityHeaders
  middleware + SecurityHeadersDefaults() with conservative defaults:
  HSTS 1y+includeSubDomains, X-Frame-Options DENY, X-Content-Type-
  Options nosniff, Referrer-Policy no-referrer-when-downgrade, CSP
  default-src 'self' + img/data + style 'unsafe-inline' (Tailwind/Vite
  needs it; scripts still 'self' only) + connect 'self' + frame-
  ancestors 'none'. Operators behind a customising reverse proxy can
  disable any header by setting its config field to empty.
- internal/config/config.go::Validate() — enforce minEncryptionKeyLength
  = 32 bytes when CERTCTL_CONFIG_ENCRYPTION_KEY is set. Empty stays
  accepted (downstream fail-closed sentinel handles it). Structured
  error names the env var, the actual length, the required minimum,
  and the canonical generation command (`openssl rand -base64 32`).

Tests:
- internal/api/middleware/securityheaders_test.go (new) — 4 cases
  (defaults present, empty value disables single header, override
  applied, headers on 4xx/5xx).
- internal/config/config_test.go — 5 new cases for the encryption-key
  length check (empty accepted, 1-byte rejected, 31-byte rejected at
  boundary, 32-byte accepted, 44-byte realistic operator key accepted).

Documentation:
- CHANGELOG.md — H-1 section above D-2 under [unreleased] with
  Breaking-change callout (operators with low-entropy keys must rotate
  before upgrade).
- coverage-gap-audit-2026-04-24-v5/unified-audit.md — Live Tracker
  25/47 → 33/47, P1 14/14 (zero remaining), P2 11/27 → 16/27. Three
  H-1 findings flipped + closed-bundle row added.

Verification:
- go build ./... — clean
- go vet ./... — clean
- golangci-lint v2.11.4 run ./... — 0 issues
- go test ./internal/api/middleware/... — pass (incl. 4 new
  SecurityHeaders cases)
- go test ./internal/config/... — pass (incl. 5 new EncryptionKey
  cases)
- tsc --noEmit (frontend) — clean
- All sibling guardrails (S-1 / G-3 / D-1 / D-2 / B-1 / L-1) still pass

Audit findings closed:
- cat-s5-4936a1cf0118 (P2)
- cat-s11-missing_security_headers (P2)
- cat-r-encryption_key_no_length_validation (P2)

Breaking change:
- Operators with CERTCTL_CONFIG_ENCRYPTION_KEY shorter than 32 bytes
  must rotate before upgrade. Generate via `openssl rand -base64 32`.

Deferred follow-ups:
- Weak-key dictionary check (reject password123, common ASCII patterns)
  — adds operational friction with low marginal entropy gain at the
  32-byte minimum.
- CSP 'unsafe-inline' for styles — required for Tailwind/Vite
  per-component <style> blocks; removing requires HTML report or
  component refactor outside H-1 scope.
- Permissions-Policy header — dashboard uses no advanced browser APIs
  (camera, mic, geolocation); deferred until a real consumer needs it.

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 a3d8b9c607 fix(deploy,db,handler): close fresh-clone postgres init failure + 4 ride-along audit findings (U-3 master)
GitHub #10 reopened: operator mikeakasully cloned v2.0.50 fresh and ran the
canonical quickstart (docker compose -f deploy/docker-compose.yml up -d --build);
postgres reported unhealthy indefinitely, dependent containers never started.

Root cause: deploy/docker-compose.yml mounted a hand-curated subset of
migrations/*.up.sql + seed.sql into postgres /docker-entrypoint-initdb.d/.
Postgres applied them at initdb time. Once seed.sql referenced columns added
by migrations *after* the mounted cutoff (e.g., policy_rules.severity from
migration 000013), initdb crashed mid-seed and the container loop wedged.
Two sources of truth (compose mount list vs in-tree migration ladder)
diverged the moment a seed-touching migration shipped, and the only thing
that fixed it was hand-editing the compose file every release.

Fix: remove the dual source. Postgres boots empty; the server applies
migrations + seed at startup via RunMigrations + RunSeed. Helm has used
this pattern since day one (postgres-init emptyDir); compose now matches.

Bundled with four ride-along audit findings whose fixes share the same
schema/db code surface, so operators take the schema-change pain only once:

  cat-u-seed_initdb_schema_drift           [P1, primary] — initdb-mount fix
  cat-o-retry_interval_unit_mismatch       [P1] — column rename minutes→seconds
  cat-o-notification_created_at_dead_field [P2] — add column + populate
  cat-o-health_check_column_orphans        [P1] — drop unwired columns
  cat-u-no_version_endpoint                [P2] — add /api/v1/version

Single migration (000017_db_coupling_cleanup) bundles the three schema
changes under a DO \$\$ guard so re-application is safe; reduces
operator-visible 'schema-change releases' from four to one.

Backend
- internal/repository/postgres/db.go: add RunSeed (baseline) + RunDemoSeed
  (gated by CERTCTL_DEMO_SEED). Both idempotent (ON CONFLICT DO NOTHING in
  every shipped INSERT) so repeated boots are safe; missing-file is no-op
  so custom packaging that strips seeds still boots cleanly.
- cmd/server/main.go: invoke RunSeed (always) + RunDemoSeed (when flag set)
  immediately after RunMigrations.
- internal/repository/postgres/notification.go: NotificationRepository.Create
  now sets created_at (with time.Now() fallback when caller leaves it zero);
  scanNotification reads it back; List + ListRetryEligible SELECT extended.
- internal/repository/postgres/renewal_policy.go: column references updated
  to retry_interval_seconds across SELECT/INSERT/UPDATE sites.
- internal/api/handler/version.go: new VersionHandler exposes
  {version, commit, modified, build_time, go_version} from
  runtime/debug.ReadBuildInfo() with ldflags-supplied Version override.
- internal/api/router/router.go: register GET /api/v1/version through the
  no-auth chain (CORS + ContentType) alongside /health, /ready,
  /api/v1/auth/info.
- cmd/server/main.go: add /api/v1/version to no-auth dispatch + audit
  ExcludePaths so rollout polling doesn't dominate the audit trail.
- internal/config/config.go: add DatabaseConfig.DemoSeed +
  CERTCTL_DEMO_SEED env var.

Migration
- migrations/000017_db_coupling_cleanup.up.sql + .down.sql:
    (1) renewal_policies.retry_interval_minutes → retry_interval_seconds
        (DO \$\$ guard, idempotent re-application)
    (2) notification_events ADD COLUMN created_at TIMESTAMPTZ
        NOT NULL DEFAULT NOW()
    (3) network_scan_targets DROP orphan health_check_enabled +
        health_check_interval_seconds
- migrations/seed.sql: column reference updated to retry_interval_seconds.
- migrations/seed_demo.sql: same column rename + applied at runtime now via
  RunDemoSeed (no longer initdb-mounted).

Compose
- deploy/docker-compose.yml: drop ALL initdb mounts (10 migration files +
  seed.sql); add start_period: 30s to postgres + certctl-server healthchecks
  to absorb the runtime migration + seed application window on first boot.
- deploy/docker-compose.test.yml: same drop (+ ghost seed_test.sql mount
  removed; that file never existed); same healthcheck start_period.
- deploy/docker-compose.demo.yml: replace seed_demo.sql initdb mount with
  CERTCTL_DEMO_SEED=true env var on certctl-server.

Tests
- internal/api/handler/version_handler_test.go: TestVersion_ReturnsBuildInfo,
  TestVersion_RejectsNonGet, TestVersion_LdflagsOverride.
- internal/repository/postgres/seed_test.go: TestRunSeed_AppliesIdempotently,
  TestRunSeed_MissingFileIsNoOp, TestRunDemoSeed_AppliesIdempotently,
  TestMigration000017_RetryIntervalRename,
  TestMigration000017_NotificationCreatedAt,
  TestMigration000017_HealthCheckOrphansDropped (testcontainers, -short skips).
- internal/repository/postgres/notification_test.go:
  TestNotificationRepository_CreatedAt_IsPersisted +
  TestNotificationRepository_CreatedAt_DefaultsToNow.

CI guardrail
- .github/workflows/ci.yml: new 'Forbidden migration mount in compose initdb
  (U-3)' step grep-fails the build if any migrations/*.sql or seed*.sql
  re-appears in /docker-entrypoint-initdb.d in any compose file. Catches
  future drift before a fresh-clone operator hits it.

Spec / Docs
- api/openapi.yaml: add /api/v1/version operation under Health tag.
- docs/architecture.md: replace the 'initdb may run the same SQL' paragraph
  with a post-U-3 single-source-of-truth explanation.
- CHANGELOG.md: full unreleased-section entry covering all 5 closures,
  breaking changes, and the new env var.

Audit doc
- coverage-gap-audit-2026-04-24-v5/unified-audit.md: add new P1 #14
  cat-u-seed_initdb_schema_drift; flip the 4 ride-along findings to
   RESOLVED with closure prose pointing at this commit.

Verification: build/vet/test -short -race all clean across all touched
packages locally; govulncheck reports 0 vulnerabilities affecting our
code; OpenAPI YAML parses; CI U-3 grep guardrail clears against the
post-fix tree.

shankar0123 9c1d446e40 fix(security,config): remove unimplemented JWT auth-type, close silent downgrade (G-1)
The pre-G-1 config validator accepted CERTCTL_AUTH_TYPE=jwt and the
startup log faithfully echoed 'authentication enabled type=jwt'.
Reasonable people read that and concluded JWT auth was on. It wasn't.
The auth-middleware wiring at cmd/server/main.go unconditionally routed
every request through the api-key bearer middleware regardless of
cfg.Auth.Type. So CERTCTL_AUTH_TYPE=jwt quietly compared the incoming
'Authorization: Bearer <token>' against whatever string the operator put
in CERTCTL_AUTH_SECRET — real JWT clients got 401, and operators who
treated CERTCTL_AUTH_SECRET as a *signing* secret (because they thought
they were configuring JWT) had effectively handed an attacker an api-key.
A security finding masquerading as a config option.

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

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

Files changed:

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

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

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

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

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

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

Out of scope (explicitly untouched):
- internal/connector/discovery/gcpsm/gcpsm.go — Google OAuth2 service-

shankar0123 9834b4e4a4 G-1: renewal-policies API + frontend FK-drift fix
Three frontend call sites (OnboardingWizard.tsx:603, CertificatesPage.tsx:52,
CertificateDetailPage.tsx:169) populated the renewal_policy_id dropdown from
getPolicies() — the compliance-rule endpoint returning pol-* IDs — which
violated the FK managed_certificates.renewal_policy_id REFERENCES
renewal_policies(id) ON DELETE RESTRICT. Create would fail pg 23503 at insert.

Backend (new):
- RenewalPolicyRepository CRUD + ListAll/ExistsByID (pg 23503 → ErrRenewalPolicyInUse
  → HTTP 409; pg 23505 → ErrRenewalPolicyDuplicateName → HTTP 409)
- RenewalPolicyService with repo-only constructor. Service sentinels
  var-alias the repo sentinels so errors.Is walks across layers.
- RenewalPolicyHandler with validation bounds: name 1–255;
  renewal_window_days [1,365] default 30; max_retries [0,10] not defaulted;
  retry_interval_seconds [60,86400] default 3600; alert_thresholds_days
  [0,365] default [30,14,7,0]. Auto-generated IDs rp-<slug(name)>.
- Router registers 5 routes under /api/v1/renewal-policies[/{id}].

Frontend:
- CertificatesPage/CertificateDetailPage/OnboardingWizard now call
  getRenewalPolicies() and render rp-* IDs.
- client.ts adds getRenewalPolicies/createRenewalPolicy/updateRenewalPolicy/
  deleteRenewalPolicy. types.ts adds the RenewalPolicy shape.

OpenAPI: RenewalPolicies tag + 5 operations + 3 schemas (RenewalPolicy,
RenewalPolicyCreateRequest, RenewalPolicyUpdateRequest). 409 responses
on create/update duplicate-name and delete FK-in-use.

No migration — renewal_policies table already exists from the initial
schema (000001).

Tests:
- internal/service/renewal_policy_test.go: CRUD + validation + sentinel
  error wrapping.
- internal/api/handler/renewal_policy_handler_test.go: handler endpoint
  contracts including 400/404/409.
- web/src/api/client.test.ts: 4 subtests covering the 4 new API functions.

Phase 3 gates all green: go vet, build, short tests, race tests (service/
handler/router/scheduler), staticcheck (G-1 packages), govulncheck (0
reachable), coverage (service 69.7%, handler 79.0%, domain 86.9%,
middleware 80.6% — all above thresholds), tsc, vitest (256 passed),
vite build, OpenAPI structural validation.

shankar0123 52248be717 v2.0.47: HTTPS Everywhere — TLS-only control plane, agents/CLI/MCP
Breaking change release. Plaintext HTTP listener removed. The certctl
control plane now terminates TLS 1.3 on :8443 via
http.Server.ListenAndServeTLS. No CERTCTL_TLS_ENABLED=false escape
hatch. No dual-listener mode. One-step cutover per docs/upgrade-to-tls.md.

Server
- cmd/server/tls.go: certHolder with SIGHUP hot-reload + atomic cert
  swap, buildServerTLSConfig (TLS 1.3 min, GetCertificate callback),
  preflightServerTLS validation
- cmd/server/main.go: ListenAndServeTLS in place of ListenAndServe,
  watchSIGHUP wiring, cert/key path config threading
- tls_test.go: 418-line regression coverage of reload, preflight,
  callback behavior, SAN validation

Config
- CERTCTL_TLS_CERT_PATH / CERTCTL_TLS_KEY_PATH (required)
- Plaintext rejection: agents/CLI/MCP pre-flight-fail on http://
  URLs with a pointer to docs/upgrade-to-tls.md

Agents, CLI, MCP
- All three pre-flight-reject http:// URLs with fail-loud diagnostic
- CERTCTL_SERVER_CA_BUNDLE_PATH for private-CA trust
- CERTCTL_SERVER_TLS_INSECURE_SKIP_VERIFY for dev-only bypass
  (loud warning on startup)
- install-agent.sh emits both vars as commented template lines

docker-compose
- certctl-tls-init sidecar generates SAN-valid self-signed cert into
  deploy/test/certs/ on first boot
- All demo-stack curls pin against ca.crt with --cacert

Helm chart
- Three TLS provisioning modes, exactly one required:
  - server.tls.existingSecret (operator-supplied)
  - server.tls.certManager.enabled (cert-manager integration)
  - server.tls.selfSigned.enabled (eval only — not for production)
- server-certificate.yaml template for cert-manager mode
- helm install without a TLS source fails at template render with
  a pointer to docs/tls.md

CI
- .github/workflows/ci.yml Helm Chart Validation step renders the
  chart in both existingSecret and cert-manager modes, plus an
  inverse guard-regression test that asserts helm template MUST
  refuse to render when no TLS source is configured. Previously
  the single `helm template` invocation hit the certctl.tls.required
  fail-loud guard and exit-1'd CI. Four invocations now: lint
  (existingSecret), template (existingSecret), template
  (cert-manager), template (no args — must fail).

Integration tests
- deploy/test/integration_test.go stands up the Compose stack over
  HTTPS, extracts the CA bundle, and exercises every certctl API
  over https://localhost:8443
- All 34 integration subtests green (per Phase 8 local CI-parity)

Documentation
- New: docs/tls.md (provisioning patterns, rotation, SIGHUP reload)
- New: docs/upgrade-to-tls.md (one-step cutover, no-downgrade
  warnings, fleet-roll sequencing)
- CHANGELOG.md: v2.2.0 "HTTPS Everywhere — The Irony" entry
  (file heading unchanged; release tag is v2.0.47)
- All curls in docs/, examples/, deploy/helm/ guides use
  https://localhost:8443 --cacert

Verification
- grep -rn "ListenAndServe[^T]" cmd/ internal/ → 0 hits
- grep -rn "\"http://" cmd/ internal/ → 2 benign hits (Caddy admin
  API default, SSRF doc comment) — zero certctl endpoints
- Tasks #197–#206 (Phases 0–8) all closed in the tracker

shankar0123 6e646e0fe8 M-001/M-006: strip HTTP auth from EST/SCEP + fail-loud SCEP preflight
Closes CWE-306 (missing authentication for critical function) for SCEP
via a fail-loud startup gate, and aligns EST/SCEP HTTP dispatch with
their respective RFCs. CRL/OCSP remain unauthenticated under
.well-known/pki/* per RFC 5280 §5 / RFC 6960 / RFC 8615. Option (D):
no mTLS in this milestone.

- RFC 7030 §3.2.3 (EST auth is deployment-specific) and §4.1.1
  (/cacerts explicitly anonymous): EST paths served unauthenticated;
  CSR-signature + profile policy enforce identity inside ESTService.
- RFC 8894 §3.2: SCEP authenticates via the challengePassword
  PKCS#10 attribute (OID 1.2.840.113549.1.9.7), not an HTTP credential.
  HTTP dispatch is unauthenticated; preflightSCEPChallengePassword
  refuses to start when CERTCTL_SCEP_ENABLED=true without
  CERTCTL_SCEP_CHALLENGE_PASSWORD. SCEPService.PKCSReq enforces the
  same invariant defense-in-depth and compares with
  crypto/subtle.ConstantTimeCompare.

cmd/server/main.go:
- Extract buildFinalHandler(apiHandler, noAuthHandler, webDir,
  dashboardEnabled); route /.well-known/est/*, /scep, /scep/*,
  /.well-known/pki/crl/{id}, /.well-known/pki/ocsp/{id}/{serial},
  and health probes through noAuthHandler (RequestID +
  structuredLogger + Recovery only).
- Add preflightSCEPChallengePassword fail-loud gate; startup log
  emits challenge_password_set boolean for operator visibility.

cmd/server/finalhandler_test.go (new, 314 lines, 27 subtests):
- TestBuildFinalHandler_Dispatch (20) + TestBuildFinalHandler_NoDashboard
  (7) pin the dispatch surface: EST 4-endpoint, SCEP exact +
  trailing-slash + query-string, PKI CRL+OCSP, health, /api/v1/*
  authenticated, /assets/* file server, SPA fallback.

internal/api/router/router.go, internal/config/config.go:
- Router-level comments explain why EST/SCEP/PKI dispatchers sit
  outside the authenticated mux; SCEP challenge password config
  plumbed through.

docs/architecture.md:
- New EST Authentication subsection (RFC 7030 §3.2.3 + §4.1.1,
  buildFinalHandler + noAuthHandler references).
- Rewrite SCEP Authentication subsection; replaces pre-existing
  factually-incorrect "any value accepted" claim with CWE-306
  preflight, service-layer defense-in-depth, and
  crypto/subtle.ConstantTimeCompare.
- Top-level Authentication section: qualify /api/v1/* scope on API
  clients bullet; add standards-based-endpoints bullet referencing
  the 27-subtest regression harness.

docs/compliance-soc2.md:
- CC6.1: scope API Key Authentication to /api/v1/*; add
  standards-based endpoints bullet citing RFCs and CWE-306 closure.
- CC6.3: scope API Key Policy to /api/v1/* with cross-reference to
  CC6.1.
- Evidence Locations augmented with buildFinalHandler,
  preflightSCEPChallengePassword, scep.go defense path, regression
  harness, and OpenAPI security:[] overrides.

api/openapi.yaml: verified already correct (global bearerAuth
default overridden with security:[] on /cacerts, /simpleenroll,
/simplereenroll, /csrattrs, /scep GET+POST, /crl/{issuer_id},
/ocsp/{issuer_id}/{serial}); no edits needed.

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 1ee77c89f8 I-003: job timeout reaper closes AwaitingCSR/AwaitingApproval gap
Add 11th always-on scheduler loop that transitions jobs stuck in
AwaitingCSR (default 24h TTL) or AwaitingApproval (default 168h TTL)
to Failed. I-001's retry loop then auto-promotes eligible Failed jobs
back to Pending. No new status enum, no schema migration.

- JobRepository.ListTimedOutAwaitingJobs with per-status cutoff WHERE
- JobService.ReapTimedOutJobs mirrors RetryFailedJobs structure
- Scheduler jobTimeoutLoop with atomic.Bool idempotency guard, 2m
  per-tick context, WaitGroup shutdown drain
- Config: CERTCTL_JOB_TIMEOUT_INTERVAL (10m), CERTCTL_JOB_AWAITING_CSR_TIMEOUT
  (24h), CERTCTL_JOB_AWAITING_APPROVAL_TIMEOUT (168h)
- Audit event per transition: actor=system, actorType=System,
  action=job_timeout, details={old_status, new_status, timeout_reason,
  age_hours}
- 14 new tests: 3 config, 7 service, 4 scheduler

shankar0123 0200c7f4a4 Close I-001 (RetryFailedJobs never invoked) coverage-gap finding
Operator decision answered as Option A: JobService.RetryFailedJobs is
now wired into the scheduler as an always-on 10th loop. Prior to this
commit the method was implemented, unit-tested, and exported but had
zero runtime callers — any job that transitioned to status=Failed stayed
Failed forever regardless of how many attempts it had remaining.

Scheduler — 10th loop:
  internal/scheduler/scheduler.go grows a jobRetryLoop alongside the
  existing nine loops (renewal, jobs, health, notifications, short-lived,
  network scan, digest, health check, cloud discovery). The loop follows
  the established run-immediately-then-tick pattern (same shape as
  jobProcessorLoop), gated by a sync/atomic.Bool idempotency guard and
  joined into the scheduler's sync.WaitGroup so WaitForCompletion drains
  it on graceful shutdown. Each tick runs under a 2-minute context
  timeout mirroring jobProcessorLoop's opCtx budget. The runJobRetry
  helper invokes jobService.RetryFailedJobs(ctx, 3) — the advisory
  maxRetries cap is belt-and-suspenders; per-job eligibility is still
  enforced inside the service via Attempts < MaxAttempts.

  The JobServicer scheduler-interface gains RetryFailedJobs so the
  scheduler's dependency surface stays explicit and mockable.

Service — audit trail per retry:
  internal/service/job.go:RetryFailedJobs now emits an audit event for
  every Failed→Pending transition. Following the house convention used
  by all scheduler-emitted events, actor='system' and actorType=
  domain.ActorTypeSystem; action='job_retry'; details capture
  old_status, new_status, attempts, max_attempts. JobService carries an
  optional *AuditService (SetAuditService) that nil-guards to preserve
  test-wiring ergonomics — existing tests that construct JobService
  without an audit service continue to pass unchanged.

Config — env var with sane default:
  internal/config/config.go:SchedulerConfig grows RetryInterval, wired
  to CERTCTL_SCHEDULER_RETRY_INTERVAL with a 5-minute default. Validate
  rejects intervals below 1 second (matches other scheduler interval
  validators).

Server wiring:
  cmd/server/main.go calls jobService.SetAuditService(auditService)
  after JobService construction and sched.SetJobRetryInterval(
  cfg.Scheduler.RetryInterval) alongside the other SetXxxInterval calls.

Regression coverage:
  internal/service/job_test.go (3 new)
    - TestJobService_RetryFailedJobs_EligibleJobTransitionsAndAudits
    - TestJobService_RetryFailedJobs_SkipsJobsAtMaxAttempts
    - TestJobService_RetryFailedJobs_NoAuditServiceOK
  internal/scheduler/scheduler_test.go (3 new)
    - TestScheduler_JobRetryLoop_CallsService
    - TestScheduler_JobRetryLoop_IdempotencyGuard
    - TestScheduler_JobRetryLoop_WaitForCompletion

  The service tests assert status transitions, attempt-cap short-
  circuiting, and audit event shape (actor='system', action='job_retry',
  details keys). The scheduler tests assert the loop invokes the service,
  the atomic.Bool guard skips overlapping ticks with the expected
  'still running, skipping tick' log, and WaitForCompletion drains the
  in-flight tick on Stop.

Residual follow-up (not in scope for this commit):
  internal/service/renewal.go:RetryFailedJobs is a parallel dead-code
  duplicate of the same logic on RenewalService — untested and has no
  runtime caller. The audit finding called this out as 'implemented
  twice'. Removing it is a separate cleanup and does not block the
  Option-A wiring this commit delivers.

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

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

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

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

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

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

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

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

shankar0123 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 d14a45401b fix(audit): drain in-flight recording goroutines on shutdown (M-1)
Audit events spawned from the HTTP middleware ran in detached goroutines
using context.Background(). On SIGTERM the DB pool was closed before
those goroutines finished writing, silently dropping audit events
(CWE-662 Improper Synchronization / CWE-400 Uncontrolled Resource
Consumption).

NewAuditLog now returns an *AuditMiddleware struct that tracks every
spawned goroutine with sync.WaitGroup. Callers wire the middleware via
its Middleware method value (preserves the existing
func(http.Handler) http.Handler shape) and drain the WaitGroup with
Flush(ctx), which blocks until in-flight recordings complete or the
provided context is cancelled — mirroring scheduler.WaitForCompletion.

Flush is invoked in cmd/server/main.go between http.Server.Shutdown
(no new requests accepted) and db.Close (pool torn down), with a
timeout returning ErrAuditFlushTimeout wrapping ctx.Err().

Request-derived inputs (method, path, status) are snapshotted before
the goroutine spawn so the worker does not race with http.Server
reusing r after the handler returns.

Tests:
  TestAuditLog_FlushDrainsInFlightGoroutines
  TestAuditLog_FlushTimeoutReturnsErrAuditFlushTimeout

shankar0123 27afa4463d fix(repository): idempotent sentinel agent creation via ON CONFLICT (M-6)
Sentinel agents (server-scanner, cloud-aws-sm, cloud-azure-kv,
cloud-gcp-sm) were created on startup with a plain INSERT whose
duplicate-key error was swallowed unconditionally. That silenced every
other DB failure too (connectivity drop, permissions change, unrelated
constraint violation) — a restart after the first boot quietly
de-fanged cloud discovery and the network scanner (CWE-662, CWE-209-
adjacent).

Shape A: add AgentRepository.CreateIfNotExists using ON CONFLICT (id)
DO NOTHING RETURNING id + sql.ErrNoRows discrimination. This keeps the
strict Create semantics (duplicate-key is an error) intact for real
agent registration and gives sentinels their own idempotent path.

- repo: CreateIfNotExists returns (created bool, err error); false,nil
  on pre-existing row; false,wrapped err on anything else.
- interface: CreateIfNotExists added to AgentRepository.
- main.go: 4 sentinel sites log Error/Info/Debug distinctly.
- mocks: service + integration mocks implement the new method.
- tests: 4 new testcontainers integration tests cover first-insert,
  idempotent second-call, concurrent 16-goroutine race (exactly one
  creator, no duplicate-key panic), and pre-cancelled context
  surfacing.

Coverage gates (go test -cover): service 67.6%/55, handler 78.6%/60,

shankar0123 b813660c74 security: require SCEP challenge password when SCEP enabled (fixes H-2)
Problem (CWE-306 Missing Authentication for Critical Function):
internal/service/scep.go PKCSReq skipped the shared-secret check when
s.challengePassword was empty. An unconfigured-but-enabled SCEP server
accepted any unauthenticated client reaching /scep and issued a
certificate against the configured issuer for any CSR with a valid
signature. No audit trail distinguished authenticated from
unauthenticated enrollments. This matches the two-layer fail-closed
pattern already used for C-2 (f549a7a): reject at startup AND reject
at the service boundary.

Fix (two layers, defense-in-depth):

Layer 1 — startup pre-flight in cmd/server/main.go:
  preflightSCEPChallengePassword returns a non-nil error when SCEP is
  enabled and CERTCTL_SCEP_CHALLENGE_PASSWORD is empty. main logs and
  os.Exit(1)s before the SCEP service is constructed. Disabled SCEP is
  unaffected. The helper is unit-testable in isolation.

Layer 2 — service-layer rejection in internal/service/scep.go:
  PKCSReq refuses enrollment when s.challengePassword == "" even though
  main already blocks this state — protects future call sites (tests,
  library reuse, a REST-over-HTTPS wrapper). When a secret is
  configured, the comparison now uses crypto/subtle.ConstantTimeCompare
  so response time does not leak the configured secret through a
  short-circuiting byte compare.

Files:
- cmd/server/main.go: preflightSCEPChallengePassword helper; call site
  inside the `if cfg.SCEP.Enabled` block before issuer lookup; fatal
  slog error references CWE-306 and names the env var so operators can
  diagnose the startup failure without reading code.
- cmd/server/main_test.go: TestPreflightSCEPChallengePassword with five
  table-driven subtests (disabled empty, disabled set, enabled empty
  rejected, enabled set, single-char boundary). The enabled-empty case
  asserts the error string contains both CERTCTL_SCEP_CHALLENGE_PASSWORD
  and CWE-306 so the log message remains actionable.
- internal/config/config.go: SCEPConfig.ChallengePassword godoc now
  states the field is REQUIRED when SCEP.Enabled and cross-references
  preflightSCEPChallengePassword.
- internal/service/scep.go: imports crypto/subtle; PKCSReq rewritten
  with the two-layer check; comment block cites H-2 / CWE-306 and the
  constant-time rationale.
- internal/service/scep_test.go: existing tests that relied on the
  vulnerable empty-password path now configure a secret on both sides.
  TestSCEPService_PKCSReq_ChallengePassword_NotRequired is replaced by
  TestSCEPService_PKCSReq_ChallengePassword_EmptyServerConfigRejected
  which iterates ["", "any-value", "guess"] against an unconfigured
  server and asserts "not configured" in the error. A new
  TestSCEPService_PKCSReq_ChallengePassword_ConstantTimeLengthIndependence
  exercises same-prefix-longer and wrong-case inputs to guard against a
  regression from ConstantTimeCompare to a short-circuiting byte compare.
- internal/service/m11c_crypto_enforcement_test.go: four tests
  (RejectsWeakKey, AcceptsStrongKey, MaxTTL_ForwardedToIssuer,
  NoProfileRepo_PassesThrough) constructed NewSCEPService with an empty
  challenge password and exercised PKCSReq through the now-rejected
  vulnerable path. All four now configure "secret123" on both sides with
  an inline H-2 comment; the crypto/MaxTTL/profile behavior they assert
  is unchanged.

Wire-format / behavioral invariants preserved:
- RFC 8894 SCEP handler is untouched (internal/api/handler/scep.go and
  internal/pkcs7/*): GetCACaps/GetCACert responses, PKIOperation request
  parsing, and the PKCS#7 certs-only response format are byte-identical.
- RFC 7030 EST handler is untouched
  (internal/api/handler/est.go + internal/pkcs7/*).
- Revocation idempotency composite key (H-1, migration 000012) untouched.
- AES-256-GCM config encryption (C-2) untouched.
- CRL DER bytes and OCSP response bytes unchanged.

Verification:
- go build ./...              silent success
- go vet ./...                silent success
- go test -race -count=1 ./internal/service/ ./cmd/server/
  ./internal/api/handler/ ./internal/integration/    all OK
- Coverage with comfortable headroom over CI gates:
    service     67.8% (gate 55%)
    handler     79.0% (gate 60%)
    domain      92.7% (gate 40%)
    middleware  80.0% (gate 30%)
    cmd/server  1.6%  (preflightSCEPChallengePassword: 100%)
  internal/service/scep.go PKCSReq statement coverage: 100%.
- rg sweeps: no `s.challengePassword != ""` remains;
  no `challengePassword != s.challengePassword` remains.

Operational note: operators with SCEP enabled but no challenge password
set will see a fatal startup error and a log line citing
CERTCTL_SCEP_CHALLENGE_PASSWORD and CWE-306 after upgrading. This is the
intended fail-closed behavior. Fix by either setting the env var to a
non-empty shared secret or setting CERTCTL_SCEP_ENABLED=false.

Audit report: certctl-audit-report.md (revision 5) logs this under
H-2 Resolution Log.

shankar0123 f549a7aa79 security: fail closed when CERTCTL_CONFIG_ENCRYPTION_KEY is unset (fixes C-2)
EncryptIfKeySet/DecryptIfKeySet in internal/crypto/encryption.go previously
returned plaintext + wasEncrypted=false when the operator had not configured
CERTCTL_CONFIG_ENCRYPTION_KEY. That produced a data-at-rest confidentiality
bypass (CWE-311): sensitive fields on dynamically-configured issuer and
target rows (source='database') were persisted to PostgreSQL without any
encryption, and no caller could distinguish the encrypted from the plaintext
branch at runtime. The only visible signal was a single warning log line
emitted once at startup.

Fail closed instead:

- EncryptIfKeySet / DecryptIfKeySet now return crypto.ErrEncryptionKeyRequired
  (a new exported sentinel, errors.Is-unwrappable) when the key is empty or
  nil, rather than silently emitting plaintext. The (result, wasEncrypted,
  err) tuple signature is preserved for source compatibility; only the
  semantics of the no-key branch changed.

- cmd/server/main.go grows a startup pre-flight check: if no encryption key
  is configured the server lists issuers and targets, counts rows with
  source='database', and refuses to start (os.Exit(1)) if any exist. Operators
  must either configure CERTCTL_CONFIG_ENCRYPTION_KEY or remove the exposed
  rows before the control plane can boot. The warning-only path is retained
  for the clean-slate case (no database rows).

- internal/service/issuer.go's SeedFromEnvVars now guards the encryption call
  with len(s.encryptionKey) > 0 so env-seeded rows (source='env', which are
  reconstructable on every boot from process env) continue to persist as
  plaintext in the 'config' column when no key is configured. Registry load
  already falls through to cfg.Config when EncryptedConfig is nil. GUI/API
  write paths (source='database') remain fail-closed via propagation of
  ErrEncryptionKeyRequired.

- Integration tests that exercise CreateIssuer via the handler layer now
  supply a real 32-byte AES-256 test key so the encrypt path runs instead of
  returning ErrEncryptionKeyRequired. Same pattern in internal/service/
  testutil_test.go for consolidated service-layer tests.

- internal/crypto/encryption_test.go grows regression guards:
  TestEncryptIfKeySet_EmptyKeyFailsClosed (nil_key + empty_key subtests),
  TestDecryptIfKeySet_EmptyKeyFailsClosed (nil_key + empty_key subtests),
  TestEncryptDecryptIfKeySet_RoundTripProducesDifferentCiphertext,
  TestDecryptIfKeySet_RejectsTamperedCiphertext, and
  TestEncryptIfKeySet_PreservesErrEncryptionKeyRequiredSentinel (verifies
  the sentinel unwraps through fmt.Errorf(%w)-style wrapping).

Wire format is unchanged: AES-256-GCM Encrypt/Decrypt/DeriveKey, the
12-byte nonce prefix, the GCM auth tag, the PBKDF2 salt
('certctl-config-encryption-v1'), and the 100,000 iteration count are all
byte-identical. Ciphertexts produced before this change remain decryptable.

Verified:
- go build ./... : clean
- go vet ./...   : clean
- go test -race ./internal/crypto/... ./internal/service/... \
    ./internal/integration/... ./cmd/server/... : pass
- golangci-lint run ./... : 0 issues
- govulncheck ./... : 0 reachable vulnerabilities
- rg 'return plaintext, false, nil' internal/ : no matches
- Coverage: crypto 85.0% (unchanged), service 67.8% (was 67.9%, noise),
  cmd/server 0.0% (unchanged baseline). All above CI thresholds.

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%)

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
- Conditional seeding for step-ca/OpenSSL (only when env vars set)
- GUI: source badge, connection test status on issuer detail page
