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

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

shankar0123 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'.

  Regression coverage: internal/service/discovery_test.go
    - TestDiscoveryService_ClaimDiscovered_AuditActor
    - TestDiscoveryService_DismissDiscovered_AuditActor
    - TestDiscoveryService_ClaimDiscovered_EmptyActorFallsBackToAPI
    - TestDiscoveryService_DismissDiscovered_EmptyActorFallsBackToAPI

Each new test asserts event.Actor matches the caller-supplied string (or
'api' on empty input) and explicitly asserts event.Actor != 'operator'
to lock in the historical fix intent.

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.

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

shankar0123 f2e60b93a3 feat(M11c): crypto policy enforcement — CSR validation, MaxTTL caps, key metadata
Enforce certificate profile crypto constraints across all 5 issuance paths
(renewal, agent CSR, EST, SCEP). ValidateCSRAgainstProfile() rejects CSRs
with key algorithm/size that don't match profile rules. MaxTTL enforcement
caps certificate validity per issuer connector (Local CA, Vault, step-ca
enforce directly; ACME/DigiCert/Sectigo pass through). Key algorithm and
size are now persisted in certificate_versions for audit compliance.

16 new tests (12 service-layer + 4 Local CA connector). Removes hardcoded
version number from GUI sidebar. Documentation updated across architecture,
features, connectors, and README.

shankar0123 7382e5f03b test: comprehensive test gap closure across 24 packages
Close coverage gaps identified by dual-audit (qualitative + quantitative).
New test files for config (0%→98%), router (0%→100%), handler validation,
health, audit, response helpers, webhook notifier (0%→88%), email notifier,
middleware (recovery, rate limiter), domain profile, service nil-safety,
config helpers, issuer bootstrap, and server bootstrap wiring. Expanded
existing tests for ACME (34%→42%), step-ca (42%→52%), F5, SSH, agent
(43%→63%), scheduler (88%→99%), renewal service, and issuerfactory.

All tests pass: go test -short, go vet, go test -race clean.

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 ec0e7a3560 feat: wire ARI (RFC 9702) into renewal scheduler
CheckExpiringCertificates() now queries each issuer's ARI endpoint
before creating renewal jobs. If the CA says "not yet" (suggested
window hasn't opened), renewal is deferred. ARI errors fall back
gracefully to threshold-based logic. Audit trail records
renewal_trigger=ari when ARI drives the decision.

4 new unit tests: ShouldRenewNow, NotYet, NilFallback, ErrorFallback.
3 new smoke tests in testing-guide.md Part 35.

Add certificate export in PEM (JSON or file download) and PKCS#12 formats.
Private keys are never included — they stay on agents. Add EKU-aware
issuance threading profile EKUs (serverAuth, clientAuth, codeSigning,
emailProtection, timeStamping) through the full issuance pipeline. Fix
agent CSR SAN splitting for email addresses, adaptive KeyUsage flags for
S/MIME vs TLS, and a pre-existing generateID collision bug in deployment
job creation.

shankar0123 7d14635a72 feat: add EST server (RFC 7030) for device certificate enrollment (M23)
Implement Enrollment over Secure Transport protocol with 4 endpoints under
/.well-known/est/ — cacerts (CA chain distribution), simpleenroll (initial
enrollment), simplereenroll (certificate renewal), and csrattrs (CSR
attributes). PKCS#7 certs-only wire format with hand-rolled ASN.1, accepts
both PEM and base64-encoded DER CSRs, configurable issuer and profile
binding, full audit trail. 28 new tests (18 handler + 10 service).

Also includes:
- GetCACertPEM added to issuer connector interface (all 4 issuers updated)
- EST integration tests wired into e2e test suite (13 test cases)
- QA testing guide Part 26 (15 manual EST test cases)
- All docs updated: README, features, architecture, concepts, connectors,
  quickstart, demo-advanced (endpoint counts, MCP wording, agent IDs,
  issuer interface, resource lists, OpenSSL status)

shankar0123 762c523d59 feat: M15b — OCSP responder, DER CRL, short-lived exemption, revocation GUI
Backend:
- Embedded OCSP responder: GET /api/v1/ocsp/{issuer_id}/{serial} returns
  signed OCSP responses (good/revoked/unknown) using CA key
- DER-encoded X.509 CRL: GET /api/v1/crl/{issuer_id} returns proper DER CRL
  signed by issuing CA with 24h validity window
- Short-lived cert exemption: certs with profile TTL < 1 hour skip CRL/OCSP
  (expiry is sufficient revocation for ephemeral workloads)
- Extended issuer connector interface with GenerateCRL and SignOCSPResponse
- Local CA implements full CRL/OCSP signing; ACME and step-ca return
  appropriate "use native endpoint" errors
- IssuerConnectorAdapter bridges new methods between layers

Frontend:
- Revoke button on certificate detail page with RFC 5280 reason modal
- Revocation banner with reason display and timestamp
- Revocation status indicators in lifecycle section
- "Revoked" filter option in certificates list
- API client: revokeCertificate() function and Certificate type extensions

Tests: ~31 new tests across connector, service, handler, and adapter layers
Docs: milestones renumbered (M13-M14, M16-M18), M15b marked complete

and email revocation notifications, best-effort issuer notification, and immutable
revocation audit trail. Includes 48 new tests across service, handler, integration,
and domain layers (600+ total). Fixes 3 pre-existing test bugs (team_test error
matching, agent_group delete status code, team handler per_page validation).

Agents now report OS, architecture, IP address, hostname, and version
via heartbeat using runtime.GOOS, runtime.GOARCH, and net.Dial. New
migration adds columns to agents table. Heartbeat handler, service,
and repository updated to accept and persist metadata. GUI shows
OS/Arch in agent list and full system info in agent detail page.

Apache httpd connector: separate cert/chain/key files, apachectl
configtest validation, graceful reload. HAProxy connector: combined
PEM file (cert+chain+key), optional config validation, reload.
Both wired into agent binary's target connector switch.

14 tests for new connectors. All existing tests updated for new
Heartbeat/UpdateHeartbeat signatures. Docs updated across README,
architecture, concepts, and connectors guides.
