PR-E of 6 in the M-2 end-to-end remediation sequence. Collapses the
HeartbeatWithContext wrapper into a single ctx-first Heartbeat method,
matching D-1 (ctx-only signatures, no dual forms). The handler-facing
method name is preserved (D-4) — internal/api/handler/agents.go already
declares `Heartbeat(ctx, ...)` on its local service interface, and the
handler mock at internal/api/handler/agent_handler_test.go already
takes `_ context.Context` as its first param, so no handler churn.
Changes
-------
internal/service/agent.go
- Delete the zero-body Heartbeat wrapper that forwarded to
HeartbeatWithContext with context.Background().
- Rename HeartbeatWithContext → Heartbeat (ctx-bearing body
folded directly into the canonical method).
internal/service/agent_test.go
- TestHeartbeat (L95) and TestHeartbeat_NotFound (L128):
agentService.HeartbeatWithContext(ctx, ...) → .Heartbeat(ctx, ...).
internal/service/concurrent_test.go
- L162: agentSvc.HeartbeatWithContext(ctx, agentID, metadata)
→ .Heartbeat(ctx, agentID, metadata).
internal/service/context_test.go
- L179 + L232: agentSvc.HeartbeatWithContext(ctx, ...) → .Heartbeat(...)
- L185 + L238 t.Logf strings: "HeartbeatWithContext with ..." →
"Heartbeat with ..." to match the collapsed method name.

Collapse CancelJobWithContext into CancelJob; eliminate 10 context.Background()
hits across the Job+Notification+Audit service cluster by threading ctx
through their handler-facing service interfaces.
Services (ctx-first):
- service/job.go: ListJobs, GetJob, CancelJob, ApproveJob, RejectJob now
accept ctx; the CancelJobWithContext wrapper is removed (handler callers
continue to invoke CancelJob, now ctx-aware).
- service/notification.go: ListNotifications, GetNotification, MarkAsRead
accept ctx.
- service/audit.go: ListAuditEvents, GetAuditEvent accept ctx.
Handlers (interface + callsites):
- handler/jobs.go, handler/notifications.go, handler/audit.go: local
service interfaces updated, r.Context() threaded at every callsite.
Tests:
- Mock services updated to match the new interfaces (ctx accepted and
ignored via '_ context.Context' first parameter; Fn closure fields
unchanged).
- job_test.go / notification_test.go callsites thread context.Background()

Collapses CertificateService, RevocationSvc, and CAOperationsSvc to
ctx-accepting method signatures. Removes context.Background() synthesis
at 24 internal call sites across certificate.go, revocation_svc.go, and
ca_operations.go.
- Primary repo calls inherit request cancellation via the passed ctx.
- Audit and notification dispatches use context.WithoutCancel(ctx) so
they survive client disconnect.
- Collapses TriggerRenewal/TriggerRenewalWithActor,
TriggerDeployment/TriggerDeploymentWithActor, and
RevokeCertificate/RevokeCertificateWithActor sibling pairs into single
canonical ctx-accepting methods (decisions D-1, D-2).
Handlers pass r.Context(). Mocks and tests updated to match new
signatures. No HTTP surface change, no OpenAPI change.

Sentinel agents (server-scanner, cloud-aws-sm, cloud-azure-kv,
cloud-gcp-sm) were created on startup with a plain INSERT whose
duplicate-key error was swallowed unconditionally. That silenced every
other DB failure too (connectivity drop, permissions change, unrelated
constraint violation) — a restart after the first boot quietly
de-fanged cloud discovery and the network scanner (CWE-662, CWE-209-
adjacent).
Shape A: add AgentRepository.CreateIfNotExists using ON CONFLICT (id)
DO NOTHING RETURNING id + sql.ErrNoRows discrimination. This keeps the
strict Create semantics (duplicate-key is an error) intact for real
agent registration and gives sentinels their own idempotent path.
- repo: CreateIfNotExists returns (created bool, err error); false,nil
on pre-existing row; false,wrapped err on anything else.
- interface: CreateIfNotExists added to AgentRepository.
- main.go: 4 sentinel sites log Error/Info/Debug distinctly.
- mocks: service + integration mocks implement the new method.
- tests: 4 new testcontainers integration tests cover first-insert,
idempotent second-call, concurrent 16-goroutine race (exactly one
creator, no duplicate-key panic), and pre-cancelled context
surfacing.
Coverage gates (go test -cover): service 67.6%/55, handler 78.6%/60,
domain 92.7%/40, middleware 80.0%/30, crypto 86.7%/85. Race/vet/
golangci-lint v2.11.4 (0 issues)/govulncheck v1.2.0 clean across all
touched packages.
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).

The GlobalSign Atlas HVCA connector previously used InsecureSkipVerify:true
on its mTLS TLS config, disabling server certificate validation and
defeating the purpose of the client-side mTLS handshake. This was a
CWE-295 Improper Certificate Validation vulnerability silently degrading
trust on every production call to GlobalSign's signing API.
Remediation (per H-5 audit finding, Lens 4.4):
- Remove InsecureSkipVerify from all three http.Client construction sites
(ValidateConfig, getHTTPClient, and legacy initialisation path).
- Introduce buildServerTLSConfig() helper that constructs tls.Config with
MinVersion: tls.VersionTLS12 (addresses adjacent L-1 recommendation).
- New optional config field `server_ca_path` (env:
CERTCTL_GLOBALSIGN_SERVER_CA_PATH). When unset the connector trusts the
system root CA bundle (correct default for GlobalSign's publicly-trusted
HVCA endpoints). When set the bundle is loaded via x509.NewCertPool() +
AppendCertsFromPEM, and only those roots are trusted (supports private
HVCA deployments and defence-in-depth root pinning).
- Error wrapping chain: "failed to read server CA bundle at %s" and
"no valid PEM certificates found in server CA bundle at %s" surface
config problems at ValidateConfig time instead of silently failing at
request time.
Docs, config, service env-seed, and GUI issuer type definition updated to
expose the new field. Tests: 9 dead `InsecureSkipVerify: true` client
TLSClientConfig blocks (no-ops against httptest.NewServer plain-HTTP)
replaced with bare http.Client; new TestGlobalSign_ServerTLSConfig covers
pinned-CA trust, untrusted-server rejection, missing-file and invalid-PEM
error paths.

The webhook notifier would previously accept any operator-configured URL
and hand it to http.Client without validation. That exposed two
SSRF classes (CWE-918):
* Reserved-address reachability — a misconfigured or adversarial
webhook URL pointing at 127.0.0.1, ::1, 169.254.169.254 (cloud
metadata), or 0.0.0.0 would succeed, exfiltrating request bodies
to local services or leaking short-lived cloud credentials.
* DNS rebinding — a hostname resolving to a public IP at validation
time and to a reserved IP at dial time would bypass any
URL-string-only check.
Fix installs two independent layers:
* validation.ValidateSafeURL runs at config-ingest time and before
every outbound POST. It rejects non-HTTP(S) schemes, empty hosts,
and literal reserved-IP hosts with a clear operator-facing error.
This is a fast early diagnostic.
* validation.SafeHTTPDialContext is installed on the webhook
http.Transport. It re-resolves the host at dial time, rejects any
resolved address whose address lies in a reserved range (loopback,
link-local, multicast, broadcast, unspecified, IPv6
link-local/multicast), and pins the resolved IP into the final
dial address so the TLS handshake targets the exact IP the guard
approved. This is the authoritative, TOCTOU-safe defence against
DNS rebinding.
The two layers are complementary — validateURL fails fast on obvious
misconfiguration; SafeHTTPDialContext fails closed when DNS changes
between validation and dial.
The existing unexported isReservedIP helper in
internal/service/network_scan.go is extracted into
internal/validation.IsReservedIP with byte-identical behaviour so the
webhook notifier and the network scanner share a single authoritative
reserved-address list. RFC 1918 ranges remain intentionally allowed
(certctl's self-hosted design). Broader unspecified / IPv6 link-local
coverage lives only in the stricter dial-time policy, where it belongs
for outbound HTTP egress.
Test seam: Connector gains an unexported validateURL func field and a
same-package newForTest constructor that installs a permissive
validator and the stdlib default transport. Production callers cannot
reach this constructor because it is unexported; only same-package
tests (package webhook) can use it. Same-package happy-path tests call
newForTest so they can point at httptest loopback servers without
being blocked by the production guard. The four SSRF-rejection tests
that verify the guard itself still call New so they exercise the real,
strict validator. This keeps the production SSRF defence
unconditionally on in real code while preserving legitimate unit-test
coverage.
Tests
-----
* internal/validation/ssrf_test.go (new) — 16-subtest pin on
IsReservedIP that is byte-identical with the original network-
scanner behaviour; ValidateSafeURL accept/reject matrix covering
HTTPS/HTTP, reserved-literal IPv4/IPv6, dangerous schemes
(file/gopher/ftp/javascript/data/ldap/dict/jar), missing hosts,
and malformed inputs; SafeHTTPDialContext rejects literal reserved
addresses and hosts resolving to reserved addresses (DNS-rebinding
coverage via localhost).
* internal/connector/notifier/webhook/webhook_test.go — happy-path
tests switched to newForTest; production-guard SSRF-rejection
tests (TestValidateConfig_RejectsReservedURLs,
TestValidateConfig_RejectsDangerousScheme,
TestPostWebhook_RejectsReservedURL,
TestPostWebhook_RejectsDangerousScheme) continue to call New so
they exercise the unconditionally-installed production validator.
Wire-format invariants preserved
--------------------------------
* Outbound HTTP request shape (method, headers, body, HMAC
signature) unchanged.
* network_scan.go behaviour unchanged — validation.IsReservedIP is
byte-identical with the deleted helper.
* RFC 1918 (10/8, 172.16/12, 192.168/16) remain allowed for both
outbound webhook and CIDR expansion, matching the self-hosted
design.
Verification
------------
* go test -race ./internal/validation/... ./internal/connector/
notifier/webhook/... ./internal/service/... — green.
* Full-suite go test -race ./... — green (GOTMPDIR=/dev/shm to
sidestep full /tmp on the sandbox host).
* Coverage gates pass: service 68.8% >= 55%, handler 83.6% >= 60%,
domain 82.0% >= 40%, middleware 63.8% >= 30%. Overall 67.8%.
Webhook package 91.5% line coverage; validation package
ValidateSafeURL/SafeHTTPDialContext 78-100% per function.
* govulncheck ./... — no vulnerabilities found.
* golangci-lint run on touched H-4 production code — clean. Pre-
existing errcheck/gosimple warnings in scope-adjacent files
(webhook_test.go:270 w.Write, network_scan.go:120/173/265/305)
verified against 3853b74 to predate this commit; left alone per
scope guard.
Operational notes
-----------------
* No migration needed. The guard is pure Go code; existing webhook
configs continue to work unless they point at reserved addresses,
in which case they now fail closed with a clear error.
* Existing operators who rely on webhook POST to 127.0.0.1 or
::1 (e.g., local receivers on the same host as certctl-server)
must expose their receiver on an RFC 1918 address or public IP.
This is deliberate — the threat model for webhook notifiers
includes untrusted operator-supplied URLs.
Scope guard: H-4 only. H-5, H-6, M-*, L-*, and I-* findings remain
open and are tracked separately. No drive-by refactors.
Problem (CWE-306 Missing Authentication for Critical Function):
internal/service/scep.go PKCSReq skipped the shared-secret check when
s.challengePassword was empty. An unconfigured-but-enabled SCEP server
accepted any unauthenticated client reaching /scep and issued a
certificate against the configured issuer for any CSR with a valid
signature. No audit trail distinguished authenticated from
unauthenticated enrollments. This matches the two-layer fail-closed
pattern already used for C-2 (f549a7a): reject at startup AND reject
at the service boundary.
Fix (two layers, defense-in-depth):
Layer 1 — startup pre-flight in cmd/server/main.go:
preflightSCEPChallengePassword returns a non-nil error when SCEP is
enabled and CERTCTL_SCEP_CHALLENGE_PASSWORD is empty. main logs and
os.Exit(1)s before the SCEP service is constructed. Disabled SCEP is
unaffected. The helper is unit-testable in isolation.
Layer 2 — service-layer rejection in internal/service/scep.go:
PKCSReq refuses enrollment when s.challengePassword == "" even though
main already blocks this state — protects future call sites (tests,
library reuse, a REST-over-HTTPS wrapper). When a secret is
configured, the comparison now uses crypto/subtle.ConstantTimeCompare
so response time does not leak the configured secret through a
short-circuiting byte compare.
Files:
- cmd/server/main.go: preflightSCEPChallengePassword helper; call site
inside the `if cfg.SCEP.Enabled` block before issuer lookup; fatal
slog error references CWE-306 and names the env var so operators can
diagnose the startup failure without reading code.
- cmd/server/main_test.go: TestPreflightSCEPChallengePassword with five
table-driven subtests (disabled empty, disabled set, enabled empty
rejected, enabled set, single-char boundary). The enabled-empty case
asserts the error string contains both CERTCTL_SCEP_CHALLENGE_PASSWORD
and CWE-306 so the log message remains actionable.
- internal/config/config.go: SCEPConfig.ChallengePassword godoc now
states the field is REQUIRED when SCEP.Enabled and cross-references
preflightSCEPChallengePassword.
- internal/service/scep.go: imports crypto/subtle; PKCSReq rewritten
with the two-layer check; comment block cites H-2 / CWE-306 and the
constant-time rationale.
- internal/service/scep_test.go: existing tests that relied on the
vulnerable empty-password path now configure a secret on both sides.
TestSCEPService_PKCSReq_ChallengePassword_NotRequired is replaced by
TestSCEPService_PKCSReq_ChallengePassword_EmptyServerConfigRejected
which iterates ["", "any-value", "guess"] against an unconfigured
server and asserts "not configured" in the error. A new
TestSCEPService_PKCSReq_ChallengePassword_ConstantTimeLengthIndependence
exercises same-prefix-longer and wrong-case inputs to guard against a
regression from ConstantTimeCompare to a short-circuiting byte compare.
- internal/service/m11c_crypto_enforcement_test.go: four tests
(RejectsWeakKey, AcceptsStrongKey, MaxTTL_ForwardedToIssuer,
NoProfileRepo_PassesThrough) constructed NewSCEPService with an empty
challenge password and exercised PKCSReq through the now-rejected
vulnerable path. All four now configure "secret123" on both sides with
an inline H-2 comment; the crypto/MaxTTL/profile behavior they assert
is unchanged.
Wire-format / behavioral invariants preserved:
- RFC 8894 SCEP handler is untouched (internal/api/handler/scep.go and
internal/pkcs7/*): GetCACaps/GetCACert responses, PKIOperation request
parsing, and the PKCS#7 certs-only response format are byte-identical.
- RFC 7030 EST handler is untouched
(internal/api/handler/est.go + internal/pkcs7/*).
- Revocation idempotency composite key (H-1, migration 000012) untouched.
- AES-256-GCM config encryption (C-2) untouched.
- CRL DER bytes and OCSP response bytes unchanged.
Verification:
- go build ./... silent success
- go vet ./... silent success
- go test -race -count=1 ./internal/service/ ./cmd/server/
./internal/api/handler/ ./internal/integration/ all OK
- Coverage with comfortable headroom over CI gates:
service 67.8% (gate 55%)
handler 79.0% (gate 60%)
domain 92.7% (gate 40%)
middleware 80.0% (gate 30%)
cmd/server 1.6% (preflightSCEPChallengePassword: 100%)
internal/service/scep.go PKCSReq statement coverage: 100%.
- rg sweeps: no `s.challengePassword != ""` remains;
no `challengePassword != s.challengePassword` remains.
Operational note: operators with SCEP enabled but no challenge password
set will see a fatal startup error and a log line citing
CERTCTL_SCEP_CHALLENGE_PASSWORD and CWE-306 after upgrading. This is the
intended fail-closed behavior. Fix by either setting the env var to a
non-empty shared secret or setting CERTCTL_SCEP_ENABLED=false.
Audit report: certctl-audit-report.md (revision 5) logs this under
H-2 Resolution Log.
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.
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.

Replaces math/rand-based agent API key generation in internal/service/agent.go

generateAPIKey now returns (string, error); Register and RegisterAgent propagate

Entrust/GlobalSign/EJBCA to validIssuerTypes. Add lowercase fallbacks
to issuer factory switch. 39 new test subtests covering normalization,
lowercase create flows, and M49 type acceptance.

Add three new issuer connectors completing commercial and open-source CA
coverage. Entrust uses mTLS client certificate auth with sync/async
issuance. GlobalSign Atlas uses mTLS + API key/secret dual auth with
serial-based tracking. EJBCA supports dual auth (mTLS or OAuth2) for
self-hosted Keyfactor CAs.
Each connector implements the full issuer.Connector interface (9 methods),
includes httptest-based unit tests (~14 each), and follows established
patterns (injectable HTTP clients, RFC 5280 revocation reason mapping,
CRL/OCSP delegated to CA).
Also includes: issuer factory cases, env var seeding, config structs,
domain types, seed data (3 rows, all disabled), OpenAPI enum updates,
frontend issuer catalog entries with config fields, and full docs
(connectors.md, architecture.md, features.md, README).

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.

Implements Simple Certificate Enrollment Protocol with single-endpoint
operation-based dispatch (GetCACaps, GetCACert, PKIOperation), PKCS#7
SignedData CSR extraction with fallback for raw/base64 CSR, challenge
password authentication via CSR attributes, and shared internal/pkcs7
package extracted from EST handler to eliminate code duplication.
24 new tests (11 service + 13 handler) plus 5 shared pkcs7 package tests.

Rewrote docs/features.md from scratch as authoritative feature inventory
(1255 lines, every claim verified against source files).
Audited README.md and architecture.md against repo — fixed 19 stale
references: K8s Secrets status, issuer counts, dashboard page counts,
CI thresholds, missing connectors in Mermaid diagrams, OpenAPI operation
count, GetCACertPEM behavior, and V2/V4 roadmap accuracy.
Also includes related fixes discovered during audit:
- Scheduler skips expired/failed/revoked certs from auto-renewal
- Seed demo expiry dates moved outside 31-day scheduler query window
- Agent pages use correct last_heartbeat_at field name

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.

Full audit of all ~100 backend API endpoints against frontend client functions
and TypeScript interfaces. Fixes field name mismatches, missing client functions,
phantom interface fields, type coercion for Go bool/int config fields, and
issuer type ID alignment with backend domain constants.
Backend:
- issuer.go/target.go: GUI-created entities default enabled=true (Go bool
zero value was overriding DB DEFAULT)
Frontend types (types.ts):
- Certificate: fingerprint→fingerprint_sha256, phantom fields made optional
- CertificateVersion: fingerprint→fingerprint_sha256, chain_pem→pem_chain,
removed phantom version/cert_pem fields
- Job: error_message→last_error (matches Go json tag)
Frontend client (client.ts):
- Added getNotification(id) and getAuditEvent(id) for existing backend routes
Frontend pages:
- CertificateDetailPage: derives serial/fingerprint/issuedAt from latest
CertificateVersion instead of empty Certificate fields
- JobsPage/JobDetailPage: error_message→last_error
- TargetsPage: reload_cmd→reload_command, validate_cmd→validate_command,
added missing config fields per backend structs (validate_command for
NGINX/Apache, hostname/winrm_timeout for IIS, private_key/passphrase/
cert_mode/key_mode for SSH, winrm_https/winrm_insecure for WinCertStore,
create_keystore for JavaKeystore, mode for Dovecot), type coercion via
buildConfigPayload() with BOOL_FIELDS/INT_FIELDS sets, IIS WinRM nesting
- TargetDetailPage: added passphrase to sensitiveKeys redaction
- issuerTypes.ts: type IDs aligned to backend constants (acme→ACME,
local→GenericCA, stepca→StepCA, openssl→OpenSSL), backward compat aliases
preserved, step-ca config fields updated to match backend struct
Utilities (utils.ts):
- formatDate/formatDateTime accept string|undefined|null

Three related ACME ecosystem changes shipped as a single milestone:
1. ACME Certificate Profile Selection: Custom JWS-signed newOrder POST with
`profile` field (e.g., `tlsserver`, `shortlived` for 6-day certs) bypassing
acme.Client.AuthorizeOrder() since golang.org/x/crypto lacks profile support.
ES256 JWS signing with kid mode, nonce management, directory discovery.
Empty profile delegates to standard library path (zero behavior change).
Configurable via CERTCTL_ACME_PROFILE env var. GUI: profile dropdown on
ACME issuer config.
2. ARI RFC 9702 → 9773 Renumber: All 25+ references updated across Go source,
docs, README, and examples. Zero remaining occurrences of RFC 9702.
3. 45-Day / Short-Lived Certificate Positioning: 5 domain tests validating
renewal thresholds against SC-081v3 validity reduction timeline (200→100→47
days) and Let's Encrypt 45-day/6-day profiles. ARI (RFC 9773) is the
expected renewal path for 6-day shortlived certs.
New tests: 13 profile + 5 domain threshold + 1 frontend = 19 new tests.

Adds a new target connector enabling certificate deployment to any
Linux/Unix server without installing the certctl agent binary. Uses the
proxy agent pattern — a single agent in the same network zone deploys
certs to remote servers over SSH/SFTP.
Key additions:
- SSH/SFTP connector with key auth (file/inline) + password auth
- Injectable SSHClient interface for cross-platform testing (25 tests)
- Shell injection prevention via validation.ValidateShellCommand()
- Configurable cert/key/chain paths with octal permissions
- GUI: 11 SSH config fields in target create wizard
Also fixes pre-existing frontend bug where all target type strings
(nginx, apache, etc.) were sent as lowercase but the backend expects
proper-case (NGINX, Apache, etc.), breaking GUI-created targets.
Adds missing TargetTypeSSH to validTargetTypes service map.

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.

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

Fixes 12 production bugs preventing the full issuance→deployment flow
from working with ACME (Pebble/Let's Encrypt) and step-ca issuers:
ACME connector (acme.go):
- Save orderURI before WaitOrder overwrites it (Go crypto/acme bug)
- Add CreateOrderCert fallback via WaitOrder+FetchCert
- Remove defer-reset in ValidateConfig that caused nil pointer panic
- Add Insecure TLS option for self-signed ACME servers (Pebble)
step-ca connector (stepca.go, jwe.go):
- Real JWE provisioner key loading + decryption (was using ephemeral keys)
- Fix JWT audience (/1.0/sign), sha claim (key fingerprint), kid header
- Custom root CA trust via RootCertPath config
- Remove hardcoded 90-day validity default (let step-ca decide)
NGINX target connector (nginx.go):
- Use sh -c for validate/reload commands (shell interpretation)
- Use filepath.Dir instead of fragile string slicing
- Add private key file writing (agent-mode keys were never deployed)
- Make chain_path write conditional
Server/service layer:
- TriggerRenewalWithActor now creates actual Job records (was no-op)
- createDeploymentJobs falls back to DB query when cert.TargetIDs empty
- ProcessPendingJobs skips agent-routed deployment jobs
- Agent cert pickup path parsing: len(parts)<4 → len(parts)<3
- Health/ready/auth-info endpoints bypass auth middleware
- Write timeout 15s→120s for ACME issuance
- Cert fingerprint computed on CSR submission
Integration test environment (deploy/test/):
- 10-phase test script covering Local CA, ACME, step-ca, revocation,
discovery, renewal, and API spot checks
- Docker Compose with 7 containers (server, agent, postgres, nginx,
pebble, challtestsrv, step-ca) on isolated network
- TLS verification checks SAN (not just Subject CN) for modern CA compat

Issuer Catalog (M33):
- Shared issuer type config (issuerTypes.ts) with 6 supported + 2 coming-soon types
- Composable wizard components (TypeSelector, ConfigForm, ConfigDetailModal)
- Catalog card layout with Connected/Available/Coming Soon badges
- VaultPKI and DigiCert added to create wizard with full config fields
- ACME EAB fields (eab_kid, eab_hmac with sensitive flag)
- Issuer type filter dropdown on configured issuers table
- Config detail modal replacing 60-char truncation
- IssuerDetailPage uses shared typeLabels/redactConfig, Edit button, enabled/disabled status
- StatusBadge extended with Enabled/Disabled styles
- 2 new frontend tests (VaultPKI + DigiCert create payload verification)
Bug fixes:
- CertificateService.CreateCertificate now defaults Status to Pending and Tags to
empty map when not set (DB column DEFAULTs only apply when columns are omitted
from INSERT, but our repo always includes all columns)
- CreateCertificate handler now logs actual error via slog.Error before returning
generic 500, enabling root cause debugging

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

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.

Root cause: certificate_versions.csr_pem is nullable in the schema but
Go code scanned it into a plain string. Used sql.NullString in
ListVersions and GetLatestVersion to handle NULL values correctly.
Also includes: partial update fetch-merge-update pattern to prevent FK
violations, nil directory guard in discovery service, diagnostic slog
logging in handlers, export handler 422 for unparseable PEM, OpenAPI
spec corrections, MCP tool description improvements, and test fixes.
Rewrites the Release Sign-Off section in testing-guide.md to individual
test-level granularity (320 rows) with smoke test results audited and
checked off (121 pass, 5 skip, 194 manual remaining).

- Use type conversion DigestStatusCount(c) instead of struct literal
- Replace with...else-if (invalid in Go templates) with if...else-if chain

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.

- 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)

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.
