shankar0123 43836aca7c feat(audit): COMP-001-HASH — per-row hash chain on audit_events (tamper-evidence)
Sprint 6 closure of the audit's HIGH-severity COMP-001-HASH finding.

Pre-fix posture: migration 000018 installs a WORM trigger on
audit_events that blocks UPDATE / DELETE for the application role.
But the trigger header itself documents a compliance-superuser
bypass (backup restore, retention purges, breach recovery). Without
a hash chain, that role can rewrite any row's actor / action /
details / timestamp / event_category with no on-disk trace.

HIPAA §164.312(b), FedRAMP AU-9, NIST 800-53 AU-10 want tamper-
EVIDENCE, not just tamper-prevention. This commit ships the
evidence layer.

Wire shape:

  migrations/000047_audit_events_hash_chain.up.sql
    + pgcrypto extension (digest function)
    + audit_chain_head: single-row sentinel table holding the most
      recent row_hash; FOR UPDATE row-lock serialises chain writes
      under concurrent INSERTs so two parallel writers can't read
      the same prev_hash and produce a forked chain
    + audit_events: prev_hash + row_hash columns
    + audit_events_canonical_payload(): centralised hash input
      builder. UTC + microsecond ISO-8601 keeps the hash session-
      timezone-independent. All columns separated by '|' so a
      concatenation-ambiguity exploit can't fabricate a collision
    + audit_events_compute_hash_chain(): BEFORE-INSERT trigger
      function. Reads sentinel FOR UPDATE → computes
      sha256(prev_hash || id || actor || actor_type || action ||
      resource_type || resource_id || details::text ||
      timestamp_utc_iso || event_category) → writes both columns +
      advances the sentinel
    + backfill loop walks every existing row in (timestamp ASC, id
      ASC) order; WORM trigger temporarily DISABLEd inside this
      migration's transaction so backfill UPDATEs land cleanly,
      ENABLEd before COMMIT
    + audit_events_verify_chain(): STABLE plpgsql verifier. Walks
      the chain end-to-end and returns the first break:
        (first_break_id TEXT, first_break_pos INT, row_count INT)

  internal/repository/postgres/audit.go
    + AuditRepository.VerifyHashChain — calls the SQL function and
      maps the OUT parameters to Go return values

  internal/repository/interfaces.go
    + AuditRepository.VerifyHashChain in the contract; every
      in-memory mock + stub picks up the no-op implementation

  internal/scheduler/scheduler.go
    + AuditChainVerifier + AuditChainBreakRecorder interfaces
    + auditChainVerifyInterval (default 6h)
    + auditChainVerifyLoop: runs once on start + every tick;
      atomic.Bool guard + 5-min per-tick context timeout match every
      other GC loop's pattern

  internal/service/audit_chain_metric.go
    + AuditChainCounter type with atomic counters. Sticky-first-
      detection on (BrokenAtID, BrokenAtPos) so the actionable
      alarm doesn't drift across walks. Snapshot() returns the
      full state for the metrics handler

  internal/api/handler/metrics.go
    + AuditChainCounterSnapshotter interface + Prometheus
      exposition for four series:
        certctl_audit_chain_break_detected_total counter (the alarm)
        certctl_audit_chain_verify_total          counter (walks done)
        certctl_audit_chain_rows                  gauge (last walk size)
        certctl_audit_chain_last_verified_at      gauge (unix seconds)

  internal/config/config.go
    + AuditChainConfig{ VerifyInterval } + CERTCTL_AUDIT_CHAIN_VERIFY_INTERVAL

  cmd/server/main.go
    + wires AuditChainCounter into both the scheduler (recorder) +
      metrics handler (snapshotter) — single instance shared so the
      writer + reader are guaranteed to converge

  internal/repository/postgres/audit_chain_test.go (NEW)
    + TestAuditEventsHashChain_FreshTable: empty walk → clean
    + TestAuditEventsHashChain_AppendLinksRows: three INSERTs
      produce a strictly-linked chain; prev_hash on row 0 is NULL;
      verifier walks clean over the 3 rows
    + TestAuditEventsHashChain_VerifierDetectsTampering: simulate
      the compliance-superuser threat model (DISABLE WORM, UPDATE
      a middle row, ENABLE WORM); verifier returns the tampered
      row's id at position 1

  docs/operator/audit-chain.md (NEW)
    + Layered-defenses explainer (WORM + hash chain). Verifier
      function reference. Recommended Prometheus alert rule.
      Performance scaling table (10k to 10M rows). Step-by-step
      runbook for what to do when a break is detected. Operator
      configuration table.

shankar0123 a485e31f63 fix(repo,service): SCALE-002 — push pagination into SQL for target/issuer/team/agent_group
Sprint 2 unified-master-audit closure. Pre-fix four service List
endpoints (target, issuer, team, agent_group) called repoFoo.List(ctx)
to fetch the full table then sliced in memory:

    rows, _ := s.repo.List(ctx)
    total := int64(len(rows))
    start := (page - 1) * perPage
    end := start + perPage
    return rows[start:end], total, nil

This page-sliced in memory pattern marshals every row per request —
fine on small fleets but unacceptable for multi-tenant or large-fleet
deploys. The agent_group case was worse — the service explicitly
ignored page/perPage and returned the entire slice.

Fix:
  - New ListPaginated(ctx, limit, offset) method on each of the four
    repositories. Postgres implementations push LIMIT + OFFSET into
    the SQL plus a SELECT COUNT(*) for the total. Mirrors the cursor
    pattern already in internal/repository/postgres/certificate.go.
  - Each ListPaginated normalises limit≤0→50 and offset<0→0,
    matching the service-layer defaults that already existed.
  - Repository interfaces grow the new method so adapters stay
    swappable.
  - Service List methods now call repoFoo.ListPaginated(ctx, perPage,
    (page-1)*perPage) directly — no more memory-slice.
  - AgentGroupService.ListAgentGroups closes the Bundle E / Audit
    L-020 'page/perPage unused' gap.

Test changes:
  - sliceWindow generic helper in testutil_test.go mirrors the SQL
    LIMIT/OFFSET semantics for in-memory mocks.
  - Six mock implementers (lifecycle_test, testutil_test x2,
    agent_group_test, team_test) gain ListPaginated methods.
  - TestTeamService_List_SCALE002_PaginationPropagatesToRepo pins
    the page=2, perPage=3 → 3 rows of 10 invariant.

Closes SCALE-002.

shankar0123 c8347d742d feat(ratelimit): Phase 13 Sprint 13.2 — postgres-backed sliding window + multi-replica test
Phase 13 Sprint 13.2 closure (architecture diligence audit ARCH-M1):
ships the infrastructure half of the ARCH-M1 substantive close. Adds a
postgres-backed sliding-window rate limiter that satisfies the same
interface as the in-memory primitive — cross-replica-consistent rather
than per-process. Sprint 13.3 wires the 5 call sites through a
backend selector (`CERTCTL_RATELIMIT_BACKEND={memory,postgres}`); this
commit deliberately changes ZERO call sites. The infrastructure +
migration ship as their own review window, mirroring the Phase 9
Sprint 8a/8b pattern.

Substantive close, not document-and-defer
=========================================
The audit recommended "document the per-process limit + defer the
distributed backend to v3." The operator chose Option M1-A (postgres-
backed; zero new infra) over the document-and-defer path. Postgres
is already a hard dependency for certctl; no new operator burden. The
multi-replica integration test in this commit is the falsifiable
closure proof — cap-N enforced exactly across N replicas hitting the
same key concurrently.

Signature ground-truth
======================
The Sprint 13.2 prompt template specified `Allow(key string) error` as
the signature to match. The actual repo signature has been
`Allow(key string, now time.Time) error` since the EST RFC 7030
hardening master bundle Phase 4.1 — the `now` parameter is what makes
the memory limiter testable against synthetic time without an
indirection through clock-injection. The new `Limiter` interface +
`PostgresSlidingWindowLimiter` match the actual repo signature
(`Allow(key string, now time.Time) error`) byte-for-byte. Per CLAUDE.md
"the repo is truth" — the prompt is framing, the code is ground-truth.

Files added
===========

migrations/000046_rate_limit_buckets.up.sql + .down.sql:
  - rate_limit_buckets(bucket_key TEXT PRIMARY KEY, timestamps
    TIMESTAMPTZ[] NOT NULL DEFAULT '{}', updated_at TIMESTAMPTZ NOT
    NULL DEFAULT NOW()).
  - btree index on updated_at supports the Sprint 13.3 janitor sweep.
  - All statements IF NOT EXISTS / DROP IF EXISTS per CLAUDE.md
    "Idempotent migrations" rule.

internal/ratelimit/limiter.go (NEW, 53 LOC):
  - Defines the `Limiter` interface with `Allow(key string,
    now time.Time) error`.
  - Compile-time satisfaction checks for both backends.
  - Doc-comment documents the prompt-vs-repo signature reconciliation
    + the Sprint 13.3 backend-selector plan + why the interface stays
    minimal (Disabled/Len are non-portable cross-backend; keeping them
    off the interface avoids leaking implementation detail).

internal/ratelimit/postgres_sliding_window.go (NEW, 178 LOC):
  - PostgresSlidingWindowLimiter struct + NewPostgresSlidingWindowLimiter
    constructor + Allow + Disabled methods.
  - Algorithm: BEGIN tx → INSERT ON CONFLICT DO NOTHING (ensures the
    row exists) → SELECT ... FOR UPDATE (per-key row lock acquired
    across the cluster) → prune in Go via the shared pruneOlderThan
    helper (single source of truth for prune semantics) → decide
    rate-limited or append → UPDATE → COMMIT.
  - SELECT FOR UPDATE is what arbitrates across replicas. Replicas A
    and B firing simultaneous Allow("k") never race because Postgres
    serializes the row-lock; the memory backend's sync.Mutex only
    arbitrates within a process.
  - Same `maxN <= 0 → disabled` opt-out semantics as the memory
    backend.
  - Empty-key short-circuit (chokepoint avoidance) matches the memory
    backend.
  - Uses pq.Array for TIMESTAMPTZ[] marshalling (lib/pq is the
    existing project driver).

internal/ratelimit/equivalence_test.go (NEW, 304 LOC):
  - Backend-equivalence suite that runs the same scenario set against
    both backends via the `Limiter` interface. 7 scenarios per
    backend: AllowsUpToCap, DistinctKeysIndependent, WindowExpiry,
    DisabledBypass, NegativeCapDisabled, EmptyKeyShortCircuits,
    ConcurrentRaceFree.
  - Memory half: TestSlidingWindowLimiter_Equivalence_Memory — runs
    on every `go test ./...`.
  - Postgres half: TestSlidingWindowLimiter_Equivalence_Postgres —
    gated by `testing.Short()`; runs only when -short is omitted, so
    `go test -race -short ./...` keeps fast.
  - Schema-per-test isolation via testcontainers-go (mirrors the
    pattern in internal/repository/postgres/testutil_test.go: setup
    one container, fresh schema per subtest, search_path-pinned DSN).
  - Memory equivalence half re-verifies the same behaviors pinned in
    the pre-existing sliding_window_test.go but through the interface
    — catches drift if SlidingWindowLimiter.Allow ever changes shape.

internal/integration/ratelimit_multi_replica_test.go (NEW, 159 LOC):
  - The falsifiable ARCH-M1 closure proof, gated by //go:build
    integration matching the rest of internal/integration/.
  - Scenario: 1 postgres container shared across N=3 independent
    *PostgresSlidingWindowLimiter instances (each replica's process
    has its own *sql.DB pool to the same database, just like a real
    HA deployment). 100 concurrent Allow("test-key") calls round-
    robin across the 3 limiters via sync.WaitGroup. Cap = 10,
    window = 1m, shared now-timestamp so the scenario is
    deterministic.
  - Assert: exactly 10 succeed + 90 return ErrRateLimited. If the
    cross-replica row lock weren't arbitrating, each replica would
    independently let through ~3-4 requests (10/3), giving 12-15
    successes. The hard-pass on exactly-10 is what makes ARCH-M1
    substantive.

What did NOT change
===================
- internal/ratelimit/sliding_window.go (the memory backend) is
  byte-identical to its pre-Sprint-13.2 state. Same Mutex, same
  Allow signature, same Len/Disabled/pruneOlderThan/evictOldestLocked.
  Compile-time check in limiter.go pins that the memory backend
  still satisfies the new interface.
- No call site in cmd/server, internal/api/handler, internal/service
  changed. Sprint 13.3 owns the 5-site migration + the
  CERTCTL_RATELIMIT_BACKEND env-var selector.
- No new operator dependency. Postgres is already required for
  certctl-server to boot. Redis (Option M1-B) was declined by the
  operator and is not introduced here.

        func NewSlidingWindowLimiter(maxN int, window time.Duration,
            mapCap int) *SlidingWindowLimiter
    var ErrRateLimited = ...
    (public surface matches the Sprint 13.2 prompt's required diff)

Sandbox note: the multi-replica integration test + the postgres
equivalence half run under testcontainers-go which requires docker-
in-docker. The CI integration job exercises both; local CI-equivalent
verification was build + vet + staticcheck + memory equivalence (the
sandbox /sessions partition is full so spinning a postgres container
locally isn't viable in this session). The Sprint 13.3 commit will
re-verify against the live integration job.

Next: Sprint 13.3 wires every call site through
ratelimit.NewLimiter(cfg.Server.RateLimitBackend, db, ...) +
introduces the scheduler janitor loop + rewrites the
docs/operator/observability.md "per-process" paragraph to describe
the configurable backend.

shankar0123 8b75e0311b chore: rename Go module path to github.com/certctl-io/certctl
Mechanical sed across the main go.mod's module declaration, the f5-mock-icontrol
sub-module's go.mod, every Go file's import path (361 files), and a rebuild of
the checked-in f5-mock-icontrol binary so its embedded build-info reflects the
new module path. No behavior change.

Choice B from cowork/transfer-certctl-to-org.md, executed 2026-05-04. Choice A
(keep module path declared as github.com/shankar0123/certctl regardless of
repo URL) shipped on the day of the org transfer (2026-05-03) since we had no
external Go consumers; this commit closes that deferral.

Backward-compat: GitHub HTTP redirects continue to forward
github.com/shankar0123/certctl → github.com/certctl-io/certctl at the URL
level, but Go's module proxy uses the path declared in go.mod as the
canonical name. Pre-fix, anyone trying `go get github.com/certctl-io/certctl/...`
hit a "module path mismatch" error because go.mod said
github.com/shankar0123/certctl and the URL they fetched it from said
certctl-io/certctl. Post-fix, the canonical name and the URL agree, so
go get / go install / external Go consumers / Go-tooling integrations
work cleanly via either the new path (preferred) or the old path (which
redirects and Go follows the redirect for source fetch).

Anyone still importing the old path inside their own code keeps working
provided they update their go.mod's `require` line to match — the module
path declared in their consumer's go.sum / go.mod is the authoritative
import name, so a mass sed across their import statements is the migration
on the consumer side. No external consumers exist today.

Diff shape:
  361 *.go files  — import path replacement only
    2 go.mod     — module declaration replacement only
    1 binary     — deploy/test/f5-mock-icontrol/f5-mock-icontrol rebuilt
                   so embedded build-info reflects the new path (8618965 vs
                   8618933 bytes; 32-byte diff is the build-info change)

  Total: 364 files, 730 insertions / 730 deletions, net-zero size, pure
  mechanical substitution.

Verification:
  gofmt: 17 files needed re-alignment after sed (the new path is one char
    shorter than the old, so column-aligned import groups drifted). Applied
    `gofmt -w` to fix.
  go mod tidy: clean exit on both modules.
  go vet ./...: clean exit.
  go build ./...: clean exit.
  go test -short -count=1 on representative packages: all green
    (internal/domain, internal/validation, internal/crypto, internal/crypto/signer,
    cmd/agent). Test output now reads `ok github.com/certctl-io/certctl/...`
    confirming the module path resolves correctly.
  binary: f5-mock-icontrol rebuilt; `strings | grep shankar0123` returns
    nothing; `strings | grep certctl-io/certctl` shows the new module path
    embedded in build-info.

Files intentionally NOT touched in this commit:
  README.md / CHANGELOG.md / docs/ / etc. — already swept to certctl-io
    URLs in commit 0729ee4 (the post-transfer URL refresh). This commit is
    purely the Go-tooling layer.
  Scarf pixels (`shankar0123.docker.scarf.sh/...`) — Scarf-account
    namespace, not a Go import or GitHub repo URL. Stays.

This is a non-blocking, non-customer-impacting change. Operators pulling
container images, running `make verify`, hitting the API, or installing the
agent see no functional difference. Only Go-tooling consumers (none today)
are affected, and they're enabled — not broken — by this commit.

shankar0123 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.

Verified locally:
- gofmt -l . clean
- go vet ./... clean
- staticcheck ./... clean
- go test -short -count=1 across connector, service, repository,
  integration, api/middleware, api/handler: green

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.

shankar0123 7cb453a336 chore(fmt): repo-wide gofmt -w sweep — close drift surfaced by ci-pipeline-cleanup Phase 4
Mechanical reformat. The new 'gofmt drift' CI step (added in
ci-pipeline-cleanup Phase 4, commit 0f205a8) surfaced 111 files
with accumulated gofmt drift across cmd/, internal/, and deploy/test/.

Each file's diff is gofmt-standard: whitespace adjustments, intra-
group import sorting (alphabetical by import path within blank-line-
separated groups), and struct-tag column alignment. No semantic
changes — verified via 'git diff --ignore-all-space' which shows only
the line-position deltas from import reordering.

The gate stays in place after this commit. Going forward it catches
gofmt drift at PR time.

shankar0123 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.

Spec preserved at cowork/est-rfc7030-hardening-prompt.md.

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 46800f3365 Bundle C tail: integration mock stub for ListJobsWithOfflineAgents
CI on the bundle-C merge (run #24970879984) failed go vet because
internal/integration/lifecycle_test.go::mockJobRepository didn't
implement the new JobRepository.ListJobsWithOfflineAgents method
that Bundle C added.

The lifecycle integration test does not exercise the offline-agent
reaper path (the unit-level test in internal/service covers that),
so the integration-mock stub is a no-op returning (nil, nil) — same
shape as the existing M-7 / I-003 stubs in this file.

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.

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 0e29c416b1 refactor(handler,repo): replace strings.Contains error dispatch with typed sentinels (S-2)
Closes one 2026-04-24 audit finding (P2):

  - cat-s6-efc7f6f6bd50: 30 strings.Contains(err.Error(), ...) sites
    in internal/api/handler/ — brittle to repository-layer message
    changes, untyped against the actual failure mode.

Approach (Option B from prompt design notes):
  - New typed sentinels in internal/repository/errors.go:
      ErrNotFound, ErrForeignKeyConstraint
      IsForeignKeyError(err) helper (the only place substring
      matching at the lib/pq boundary is allowed; isolates the
      DB-driver string knowledge to one function).
  - New typed sentinel in internal/domain/errors.go:
      ErrValidation (reserved for future per-entity validation
      wrappers; not yet used by all handlers).
  - 49 sites in internal/repository/postgres/*.go updated to wrap
    sql.ErrNoRows-derived errors via fmt.Errorf("...: %w",
    repository.ErrNotFound).
  - 18 not-found handler sites + 2 FK-constraint handler sites
    refactored to errors.Is(err, repository.ErrNotFound) /
    repository.IsForeignKeyError(err).
  - 23 inline `fmt.Errorf("X not found")` test fixtures across
    handler tests rewrapped to wrap repository.ErrNotFound.
  - test_utils.go::ErrMockNotFound rewrapped to wrap
    repository.ErrNotFound; renewal_policy.go closure docblock
    updated to reflect the new convention.
  - integration test mockJobRepository.Get wraps repository.ErrNotFound.

CI regression guardrail:
- .github/workflows/ci.yml::"Forbidden strings.Contains(err.Error())
  regression guard (S-2)" greps for the three patterns ("not found",
  "violates foreign key", "RESTRICT") under internal/api/handler/
  and fails the build on regression.

Verification:
- go build ./... — clean
- go vet ./... — clean
- go test ./... -short -count=1 — all packages pass (handler +
  repository + service + integration)
- golangci-lint v2.11.4 run ./... — 0 issues
- S-2 guardrail dry-run on post-fix tree → empty (good)
- All sibling guardrails (S-1, G-3, D-1+D-2, B-1, L-1, H-1, C-1, F-1, P-1) pass

Audit findings closed:
- cat-s6-efc7f6f6bd50 (P2)

Deferred follow-ups:
- 6 domain-specific substring patterns still inline in handlers
  ("cannot approve", "cannot reject", "cannot be parsed",
  "no certificates found", "challenge password", "invalid"/
  "required" validation chains in profiles + agent_groups). Each
  needs its own typed sentinel, scoped per service. Documented
  by the S-2 CI guardrail's allowlist for closure-comments only.
- Per-entity not-found sentinels (Option A — ErrCertificateNotFound,
  ErrAgentNotFound, etc.) deferred. Generic ErrNotFound covers the
  current dispatch needs; per-entity precision would let handlers
  return entity-aware error bodies without a domain.Type field,
  but not blocking.

shankar0123 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 4e5522a999 F-001/F-002/F-003: CRL prefix-scan, digest error sanitization, ctx-aware sleeps
F-001 (P3): GenerateDERCRL scoped to issuer via composite index
  - Add RevocationRepository.ListByIssuer leveraging migration 000012's
    idx_certificate_revocations_issuer_serial composite index as a
    prefix-scan target. Previously CAOperationsSvc.GenerateDERCRL called
    ListAll() and filtered by IssuerID in Go — O(total revocations)
    regardless of how many revocations belonged to the target issuer.
  - Rewrite GenerateDERCRL to call ListByIssuer(ctx, issuerID) so PostgreSQL
    drives a prefix scan of the composite index. Drops the in-memory filter.
  - New regression test in ca_operations_test.go asserts the CRL hot path
    invokes ListByIssuer exactly once and never ListAll, and that the
    issuerID is threaded through correctly.

F-002 (P3): digest.go admin-auth endpoints no longer leak internal errors
  - PreviewDigest (GET /api/v1/digest/preview) and SendDigest
    (POST /api/v1/digest/send) previously wrote err.Error() into the HTTP
    response body on 500s. Replace with slog.Error server-side logging plus
    a generic "internal error" response body, matching the house pattern
    in certificates.go and export.go.

F-003 (P4): three blocking time.Sleep sites now honor ctx cancellation
  - internal/connector/issuer/acme/acme.go:672 (DNS-01 propagation wait)
    now runs under a select{case <-ctx.Done(): CleanUp + return ctx.Err();
    case <-time.After(d):} so graceful shutdown doesn't get stuck behind
    the propagation delay.
  - internal/connector/issuer/acme/acme.go:786 (dns-persist-01 propagation
    wait) same pattern, returns ctx.Err() on cancel.
  - cmd/agent/main.go:272 (polling backoff inside the heartbeat loop) now
    wraps the sleep in select{case <-ctx.Done(): continue; case <-time.After(backoff):}
    so the outer <-ctx.Done() case on the parent loop fires cleanly.

Verification: build, vet, and race-enabled short tests green across all
55+ packages. govulncheck reports zero vulnerabilities in the code path.
No migration needed — F-001 reuses the existing 000012 composite index.
No frontend changes.

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

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

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

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

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

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

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

Closes I-005.

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

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

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

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

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

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

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

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

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

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

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

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

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

shankar0123 fe7e766510 Close M-004 (OCSP issuer binding) and M-005 (discovery actor propagation) coverage-gap findings
M-004 — OCSP issuer binding (composite key):
  The OCSP lookup path now binds (issuer_id, serial) as a composite key
  rather than resolving by serial alone. CertificateRepository and
  RevocationRepository gain GetByIssuerAndSerial methods; ca_operations.go
  scopes both lookups by the issuer_id path param. When no managed cert
  binds to that (issuer, serial) tuple, GetOCSPResponse constructs an
  RFC 6960 §2.2 'unknown' response (CertStatus=2) instead of the prior
  default 'good'. Short-lived cert exemption (profile TTL < 1h) is
  preserved. Real repo errors (non-sql.ErrNoRows) fail closed with a log.

  Regression coverage: internal/service/ca_operations_test.go
    - TestCAOperationsSvc_GetOCSPResponse_Unknown_CrossIssuer
    - TestCAOperationsSvc_GetOCSPResponse_Unknown_UnknownSerial

M-005 — Discovery Claim/Dismiss actor propagation:
  DiscoveryService.ClaimDiscovered and DismissDiscovered now accept an
  explicit 'actor string' parameter (propagation pattern mirrors
  bulk_revocation.go / revocation_svc.go). The handler layer passes
  resolveActor(r.Context()) — the named-key identity established by the
  M-002 auth unification — and the service falls back to 'api' (the same
  safe sentinel resolveActor uses when no auth context is present) only
  when the caller passes an empty string. Never falls back to 'operator'.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

## Verification

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

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

shankar0123 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.

shankar0123 89b910a8f1 security: atomic pending-job claim with FOR UPDATE SKIP LOCKED (H-6)
Fixes H-6 (CWE-362) — GetPendingJobs returned pending rows without row
locks, so two scheduler replicas in an HA deployment could both read the
same row, both decide it was theirs, and race on UpdateStatus, producing
duplicate Running jobs and duplicate certificate issuances.

Remediation: a claim-style repository API that selects + transitions
Pending -> Running in one transaction with SELECT ... FOR UPDATE SKIP
LOCKED. Concurrent claimants observe disjoint row sets; no worker ever
sees another worker's claimed row.

Repository changes (internal/repository/postgres/job.go):
  - New ClaimPendingJobs(ctx, jobType, limit): BEGIN; SELECT id,...
    FROM jobs WHERE status='Pending' (optional type filter, optional
    LIMIT) FOR UPDATE SKIP LOCKED; UPDATE jobs SET status='Running',
    updated_at=NOW() WHERE id = ANY($ids); COMMIT. Returns the claimed
    rows with status already flipped.
  - New ClaimPendingByAgentID(ctx, agentID): mirrors M31 UNION ALL
    semantics (direct agent_id match, target->agent JOIN fallback,
    certificate->target->agent chain for AwaitingCSR) but wraps each
    branch in FOR UPDATE SKIP LOCKED and flips Deployment/Renewal rows
    to Running. AwaitingCSR rows are returned in place (state
    transition deferred until SubmitCSR, consistent with M8 semantics).
  - Existing GetPendingJobs / ListPendingByAgentID retained for legacy
    compatibility; their godoc now directs production callers to the
    Claim* variants.

Production caller switches:
  - internal/service/job.go ProcessPendingJobs: ListByStatus(Pending)
    -> ClaimPendingJobs(ctx, "", 0). Eliminates the real scheduler
    race between two replicas tick-firing simultaneously.
  - internal/service/agent.go GetPendingWork: ListPendingByAgentID ->
    ClaimPendingByAgentID. Eliminates the race between two pollers
    for the same agent (e.g. brief network blip causing duplicate
    poll) and between a scheduler tick and an agent poll.

Safety argument for pre-flipping Pending -> Running inside the claim
transaction: ProcessRenewalJob and ProcessDeploymentJob both call
UpdateStatus(Running) unconditionally on entry, so an early flip is
idempotent. On panic, the scheduler's panic recovery leaves the job
in Running which the existing stale-running reaper handles.

Tests (internal/repository/postgres/repo_test.go, skipped in -short):
  - TestJobRepository_ClaimPendingJobs_FlipsToRunning: seed 5 Pending,
    claim once, assert all 5 returned + DB rows Running, residual
    claim returns 0.
  - TestJobRepository_ClaimPendingJobs_ConcurrentDisjoint: seed M=40
    Pending Renewals, spawn N=8 goroutines each calling
    ClaimPendingJobs(_, JobTypeRenewal, 1) in a loop. Invariants:
    (a) no job ID claimed by more than one worker, (b) sum of claims
    == 40, (c) all 40 rows in Running state in the DB. Bounded
    empty-streak guard (20 iterations) covers SKIP LOCKED transient
    zeros under contention.
  - TestJobRepository_ClaimPendingByAgentID_TransitionsDeployments:
    seeds 2 Pending Deployment + 1 AwaitingCSR for agent A plus 1
    Pending Renewal for agent B (scope check). Asserts deployments
    flip to Running, AwaitingCSR is returned but preserved, agent B's
    renewal never appears.

Mock updates: testutil_test.go, lifecycle_test.go, verification_test.go
gained ClaimPendingJobs/ClaimPendingByAgentID on their mock job repos
mirroring the real Pending -> Running semantics. Mocks intentionally
do NOT write to StatusUpdates (that map tracks UpdateStatus() call
history specifically; the real claim path uses a bulk UPDATE, not
UpdateStatus).

Verification (CI-scope):
  - go build ./cmd/...: ok
  - go vet ./...: ok
  - go test -race -short on service, api/handler, api/middleware,
    scheduler, connector/..., domain, validation, tlsprobe: ok
  - Coverage gates: service 67.6% (>=55), handler 78.6% (>=60),
    middleware 80.0% (>=30), domain 92.7% (>=40). All hold.
  - golangci-lint 2.11.4: 0 issues
  - govulncheck: no vulnerabilities in call graph
  - Frontend: tsc clean, 218 vitest tests pass, vite build ok
  - helm lint + helm template: ok
  - Invariant sweeps: FOR UPDATE SKIP LOCKED present in job.go;

shankar0123 387fb555ac security: scope revocation unique index to (issuer_id, serial_number) (fixes H-1)
RFC 5280 §5.2.3 defines certificate serial number uniqueness per issuing CA,
not globally. The prior unique index on `certificate_revocations.serial_number`
enforced a stricter invariant than the spec: with 12 issuer connectors (Local
CA, ACME, Vault, step-ca, OpenSSL, DigiCert, Sectigo, Google CAS, AWS ACM PCA,
Entrust, GlobalSign, EJBCA), two distinct certificates legitimately issued by
different CAs can share a serial number. Recording a revocation for the second
collision silently dropped via `ON CONFLICT DO NOTHING`, leaving the second
cert persistently absent from OCSP/CRL responses.

Changes:

- Migration 000012 drops `idx_certificate_revocations_serial` and creates
  `idx_certificate_revocations_issuer_serial` UNIQUE ON (issuer_id,
  serial_number). Adds a non-unique `idx_certificate_revocations_serial_lookup`
  to preserve the serial-only fast path for OCSP/CRL probes that already know
  the issuer scope.
- `CertificateRevocationRepository.Create` targets the new composite key in
  `ON CONFLICT` — same-issuer idempotency preserved, cross-issuer collisions
  now recorded as distinct rows.
- `GetBySerial(serial)` renamed `GetByIssuerAndSerial(issuerID, serial)` on
  the interface and Postgres impl. All callers (OCSP responder, CRL
  generator, short-lived-cert exemption check) already have `issuerID` in
  scope because the protocol paths carry it (`/api/v1/ocsp/{issuer_id}/{serial}`,
  `/api/v1/crl/{issuer_id}`).
- Repository integration test added: `TestRevocationRepository_CrossIssuerSerialCollision`
  asserts that serial `CAFEBABE01` can be stored under two issuers
  simultaneously, that lookups return the correct row per (issuer, serial),
  and that same-issuer idempotency still works (re-inserting (issuer, serial)
  does not error and does not duplicate).
- Existing tests and service/integration mocks updated for the rename.

Wire-format invariants preserved: CRL DER bytes, OCSP response bytes, and
AES-256-GCM config encryption are unaffected — this change touches only
revocation-record uniqueness scope.

CWE-664.

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:

shankar0123 e6088c79a3 feat(M35): dynamic target configuration with encrypted config, test connection, and GUI updates
Mirror M34's dynamic issuer config pattern for deployment targets: AES-256-GCM
encrypted config storage, sensitive field redaction in API responses, agent
heartbeat-based test connection endpoint, and full frontend updates including
test status indicators, source badges, and removal of stale hostname/status
fields from the Target interface.

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

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

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

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

shankar0123 fde5b39d53 fix: resolve test compilation and runtime failures across codebase
- Add context.Context to handler test mocks (agent, agent_group)
- Refactor scheduler to use local interfaces instead of concrete service types
- Wire RevocationSvc/CAOperationsSvc sub-services in integration tests
- Add context.Background() to service test calls (agent, agent_group)
- Fix repo integration tests: add FK prerequisite records (team, owner,
  issuer, renewal_policy) before creating certificates
- Set MaxOpenConns(1) on test DB to preserve SET search_path across queries
- Fix Apache/HAProxy tests: replace "echo ok"/"echo reload" with "true"
  binary to avoid macOS exec.Command PATH resolution failure
- Fix validation tests: correct error expectations for regex-first checks,
  replace null byte strings with strings.Repeat for length tests
- Fix scheduler timeout test flakiness with t.Skip fallback
- Remove unused imports (context in ca_operations_test, service in scheduler)

shankar0123 677c28aeca refactor(api): TICKET-006 replace 18-param RegisterHandlers with HandlerRegistry struct
Replace the 18-parameter RegisterHandlers function signature with a cleaner
HandlerRegistry struct that groups all API handler dependencies. This eliminates
the signature explosion that made the function difficult to read and maintain.

Changes:
- Added HandlerRegistry struct with 18 fields grouping all handler types
- Updated RegisterHandlers to accept a single HandlerRegistry parameter
- Updated all internal handler references to use reg.FieldName syntax
- Updated call sites in cmd/server/main.go and integration tests
- No functional changes, purely structural refactoring

shankar0123 b4ac0cda43 fix: use context.Context instead of interface{} in VerificationService interface

handler.VerificationService.

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

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

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

shankar0123 a579a84c7f feat: M11a — certificate profiles, crypto policy enforcement, short-lived cert expiry
Add certificate profiles as named enrollment templates that control allowed
key algorithms, max TTL, permitted EKUs, required SAN patterns, and optional
SPIFFE URI SANs. CSR submissions are validated against profile rules at
signing time (key type + minimum size). Short-lived certs (TTL < 1 hour)
auto-expire via a new scheduler loop — expiry acts as revocation, no
CRL/OCSP needed.

New files:
- Migration 000003: certificate_profiles table, FK columns on
  managed_certificates/renewal_policies, key metadata on certificate_versions
- domain/profile.go: CertificateProfile + KeyAlgorithmRule structs
- repository/postgres/profile.go: full CRUD with JSONB marshaling
- service/profile.go: ProfileService with validation + audit logging
- service/crypto_validation.go: CSR-against-profile validation (RSA/ECDSA/Ed25519)
- handler/profiles.go: 5 HTTP endpoints under /api/v1/profiles
- web/src/pages/ProfilesPage.tsx: profiles management page

Modified:
- renewal.go: CSR validation in CompleteAgentCSRRenewal, ExpireShortLivedCertificates
- scheduler.go: 30s short-lived expiry check loop
- certificate.go (repo): nullable profile FK, key metadata on versions
- main.go: profile repo/service/handler wiring, 8-param NewRenewalService
- router.go: 12-param RegisterHandlers with profile routes
- seed_demo.sql: 4 demo profiles (standard, mtls, short-lived, high-security)
- Frontend: types, API client, routing, sidebar nav
