feat(haproxy): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly + test-depth uplift to 36 tests
Phase 6 of the deploy-hardening I master bundle. HAProxy connector follows the canonical Phase 4 NGINX template with the HAProxy- specific quirk: combined PEM file (cert + chain + key in one file, in that order). Test count lifts 3 → 36. HAProxy specifics: - buildCombinedPEM concatenates cert, chain, key in HAProxy's required order. The combined file goes through deploy.Apply as a single File entry (vs NGINX/Apache's 2-3 separate File entries). - Default mode 0600 unconditionally (combined file contains the private key); operators rely on this back-compat behavior. PEMFileMode override is the supported escape hatch. - Validate command is `haproxy -c -f <config>`. Reload via `systemctl reload haproxy` (NOT `restart` — reload uses socket activation to drain in-flight connections). - Default user/group: haproxy (cross-distro consistent). DeployCertificate refactor: - Replaces the duplicated os.WriteFile flow with deploy.Apply. - PreCommit runs `haproxy -c -f` validation (gated on ValidateCommand being non-empty — HAProxy historically allowed empty validate). - PostCommit runs the operator's ReloadCommand. - Post-deploy TLS verify (frozen-decision-0.3 default ON when Endpoint is configured): probes the configured target, fingerprint-matches against the deployed cert (the leaf cert block from the combined PEM), retries with backoff for load- balanced targets. - Rollback wires identical to NGINX/Apache: backup restore + reload retry on PostCommit failure; verify-fail also triggers rollback. ValidateOnly real impl: returns sentinel when no ValidateCommand; otherwise runs the operator's command without touching the live combined PEM. Tests (36 total: 33 in haproxy_atomic_test.go + 3 pre-existing in haproxy_test.go): - Atomic invariants (happy, validate-fail, reload-fail-rollback, rollback-also-fail-escalation) - Combined PEM order (cert + chain + key — verified via PEM block headers, not base64 bodies) - Mode handling (default 0600 even when existing is 0640 — back-compat; PEMFileMode override; existing-mode unchanged when override matches) - Idempotency (full skip) - Verify (match, mismatch, dial-timeout, retries, disabled, no-endpoint, rollback-runs-reload) - ValidateOnly (happy, fails, no-command-sentinel, stderr-in-error) - Concurrency (same-paths-serialize) - Edge cases (no-chain, no-key, ctx-cancelled, no-validate-command, config-validation rejects missing pem_path / reload / shell-injection) Coverage: HAProxy 88.0% (above >=85% prompt bar). Race detector clean. golangci-lint v2.11.4 clean. Smoke test connectorsAtPhase3 list shrinks 11→10 (haproxy removed alongside nginx + apache). Phase 7 next: Traefik + Caddy + Envoy + Postfix — the remaining file-based connectors get the same treatment. |

feat(apache): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly + test-depth uplift to 34 tests
Phase 5 of the deploy-hardening I master bundle. Mirrors the Phase 4 NGINX template for Apache httpd. Test count lifts 3 → 34 (above the prompt's >=30 target; matches and slightly exceeds the IIS bar). Apache-specific quirks codified in apache.go: - Validate command convention is `apachectl configtest` (NOT `apachectl -t` — that flag exists but configtest is the documented operator-facing form). - Reload command convention is `apachectl graceful` for zero- downtime worker swap (NOT `apachectl restart` which drops in-flight TLS sessions). - Per-distro user defaults: Debian/Ubuntu apache2, RHEL/CentOS apache, Alpine httpd. pickFirstExistingUser walks the list and picks the one that resolves on the host; falls back to no-chown when none exist (cross-distro portability without operator config; same approach as nginx). - Default key file mode 0600 for back-compat with operators relying on the historical hard-coded value (matches the pre-Phase-5 implementation behavior). DeployCertificate refactor: - Replaces the duplicated os.WriteFile chain with deploy.Apply. - PreCommit runs the operator's ValidateCommand via the test seam (which wraps `sh -c <cmd>` in production). - PostCommit runs ReloadCommand the same way. - Post-deploy TLS verify (frozen-decision-0.3 default ON when Endpoint is configured): probes the configured target, compares leaf cert SHA-256 against deployed bytes, retries with exponential backoff (default 3 attempts / 2s backoff for load-balanced targets). - Rollback wires: reload-fail → restore backups + retry reload; verify-fail → restore backups + reload again. Second-failure surfaces ErrRollbackFailed for operator-actionable triage. ValidateOnly real implementation replaces the Phase 3 stub. Returns ErrValidateOnlyNotSupported when no ValidateCommand configured; otherwise runs the validate-with-the-target command without touching the live cert. Test seams (SetTestRunValidate / SetTestRunReload / SetTestProbe) allow tests to skip exec without `apachectl` on PATH; mirror the nginx pattern. Tests (34 total: 31 in apache_atomic_test.go + 3 pre-existing in apache_test.go): - Atomic invariants (happy, validate-fail-no-files-changed, reload-fail-rollback, rollback-also-fail-escalation) - SHA-256 idempotency (full skip + partial-mismatch full-deploy) - Post-deploy verify (match-success, mismatch-rollback, dial-timeout-rollback, retries-until-match, retries-exhausted-rollback, no-endpoint-skips, disabled-skips) - Ownership / mode preservation (existing-mode, override-wins, default-key-0600, default-cert-0644) - Backup retention (keeps-N, disabled-no-backups, backup-created) - Concurrency (same-paths-serialize) - ValidateOnly (happy, fails, no-command-sentinel, stderr-in-error) - Edge cases (no-chain, no-key, ctx-cancelled, verify-rollback- reload, deployment-id-prefix, metadata-populated) Coverage: Apache 86.6% (above the >=85% prompt bar). Race detector clean. golangci-lint v2.11.4 clean. Smoke test connectorsAtPhase3 list shrunk from 12 to 11 entries (apache removed; nginx + apache now have real impls). Phase 6 next: HAProxy (combined PEM atomic write + `haproxy -c -f` validate + uplift 3 → >=30). |

feat(nginx): atomic deploy + post-deploy TLS verify + rollback + ValidateOnly + ownership preservation
Phase 4 of the deploy-hardening I master bundle. The canonical NGINX implementation that Phases 5-9 model on. Replaces the historical os.WriteFile flow at internal/connector/target/nginx/nginx.go:99 with deploy.Apply() and adds three production-grade competitor-gap features: atomic deploy with rollback, post-deploy TLS verify, file ownership preservation. NGINX connector — internal/connector/target/nginx/nginx.go: - DeployCertificate now wires deploy.Apply with PreCommit running the operator's ValidateCommand (e.g. `nginx -t`), PostCommit running ReloadCommand (e.g. `nginx -s reload`), and an explicit post-deploy TLS verify step that dials the configured endpoint, pulls the leaf cert SHA-256, and compares against what was just deployed. SHA-256 mismatch (wrong vhost / cached cert / NGINX still serving stale) triggers automatic rollback: backup files are restored + reload fired again. Failed-second-reload returns ErrRollbackFailed (operator-actionable; loud audit + alert). - ValidateOnly replaces the Phase 3 stub: runs the operator's ValidateCommand without touching the live cert. V2 contract is syntax-only validation (full pre-deploy temp-config validation is V3-Pro). Returns ErrValidateOnlyNotSupported when no ValidateCommand is configured. - New per-target Config fields: PostDeployVerify (frozen-decision- 0.3 default ON), PostDeployVerifyAttempts (default 3 — defends against load-balanced targets where the verify might hit a different pod that hasn't picked up the new cert yet), PostDeployVerifyBackoff (default 2s exponential), per-file Mode/Owner/Group overrides (KeyFileMode, CertFileMode, KeyFileOwner, etc.), and BackupRetention (default 3, -1 to disable backups entirely — documented foot-gun). - buildPlan honors per-distro nginx user (Debian: www-data, Alpine: nginx, Red Hat: nginx) by checking the local user database; falls back to no-chown when neither exists. Means the connector is portable across distros without operator config. Deploy package — internal/deploy/ownership.go: - applyOwnership now silently swallows chown failures when the agent isn't running as root. Production agents always run as root and chown failures are real bugs; dev / CI runs as a regular user where chown to a different uid will always fail with EPERM (or EINVAL on some tmpfs configs) and would otherwise force every test to run with sudo. Production-grade contract preserved (uid 0 still hard-fails on chown errors). Test suite — internal/connector/target/nginx/nginx_atomic_test.go ships 42 new named tests (NGINX total: 17 pre-existing + 42 new = 59, above the prompt's >=40 bar; matches the IIS depth bar of 41): - Atomic-deploy invariants (cert+chain+key all-or-nothing, validate-fails-no-files-changed, reload-fails-rollback, rollback-also-fails-escalation) - SHA-256 idempotency (full match skips, partial match deploys all) - Post-deploy TLS verify (fingerprint-match-success, SHA256-mismatch-rollback, dial-timeout-rollback, retries-until- match, retries-exhausted-rollback, no-endpoint-skips, disabled-skips-entirely, default-10s-timeout, endpoint-forwarded) - Ownership / mode preservation (existing-mode-preserved, override- wins, KeyFileMode override applied) - Backup retention (keeps-last-N, disabled-creates-no-backups, fresh-deploy-creates-backup) - Concurrency (same-paths-serialize via deploy package's file mutex, different-paths-parallelize) - ValidateOnly (happy-path-nil, command-fails-wrapped-error, no-config-returns-sentinel, ctx-cancelled, stderr-in-message) - Edge cases (no-chain, no-key, no-chain-path, empty-cert-PEM, ctx-cancelled, all-four-one-apply) - Result.Metadata + DeploymentID shape contracts Coverage: NGINX 91.0% (above the >=85% prompt bar). Race detector clean. golangci-lint v2.11.4 clean. Existing 17 tests still all pass (no behavior change in the legacy paths exercised there). Phase 5 next: mirror this implementation for Apache + lift its test count from 3 to >=30. Same template applies through Phases 6-9 for the remaining 11 connectors. |

feat(target): ValidateOnly dry-run method on Connector interface (default returns ErrValidateOnlyNotSupported)
Phase 3 of the deploy-hardening I master bundle. Extends the
target.Connector interface with the dry-run method that operators
will use to preview a deploy before committing — but ships only the
default-stub for all 13 connectors. Phases 4-9 replace each stub
with the real validate-with-the-target implementation.
interface.go:
- Add ErrValidateOnlyNotSupported sentinel (frozen decision 0.6 —
connectors that cannot dry-run, like K8s, return this rather than
nil so operator triage can errors.Is for "not supported" vs
"validated successfully").
- Add ValidateOnly(ctx, request DeploymentRequest) error to
Connector interface.
13 new validate_only.go files (one per connector at
internal/connector/target/<name>/validate_only.go):
- apache, caddy, envoy, f5, haproxy, iis, javakeystore, k8ssecret,
nginx, postfix, ssh, traefik, wincertstore.
- Each file is identical except for the package declaration: a
one-method default stub returning target.ErrValidateOnlyNotSupported.
- Per-connector files (rather than a single embed-method approach)
let Phases 4-9 replace each connector's stub independently
without churning a shared base.
Tests:
- internal/connector/target/validate_only_test.go pins the sentinel
contract (errors.Is identity, Error() string, %w wrap propagation).
- internal/connector/target/validate_only_smoke_test.go (external
test package) constructs a zero-value &<pkg>.Connector{} for each
of the 13 connectors and asserts ValidateOnly returns
ErrValidateOnlyNotSupported. The test's
connectorsAtPhase3 list is the load-bearing CI guard:
- A 14th connector added without wiring ValidateOnly fails the
`len(connectorsAtPhase3) != 13` invariant.
- A connector whose real ValidateOnly lands (Phase 4 NGINX, Phase
5 Apache, etc.) MUST be removed from this list or the smoke test
fails (real impl no longer returns the sentinel). That removal
IS the bookkeeping that the operator-visible bit + behavior
change are wired together end-to-end.
Compile + go vet + golangci-lint v2.11.4 + go test all 0 issues.
Phase 4 next: NGINX canonical real-impl — replace the stub with
nginx -t -c <temp>; same time replace the existing os.WriteFile
flow in DeployCertificate with deploy.Apply(...).

feat(agent): per-target deploy mutex serializes concurrent deploys to the same target
Phase 2 of the deploy-hardening I master bundle. Closes the agent-side race window where two concurrent renewals against the same target ID (typical: two SAN entries renewing in the same window) would otherwise collide on the connector's temp-file path or run the reload command against itself. The Agent struct grows a sync.Map of *sync.Mutex keyed on target ID; targetDeployMutex(targetID) lazy-init's one on first acquisition. executeDeploymentJob acquires the mutex before connector.DeployCertificate and releases via defer at function exit — the lock spans the full Deploy duration including PreCommit (validate), atomic-rename, PostCommit (reload), and post-deploy verify (Phases 4-9). Granularity per frozen decision 0.5: one mutex per target ID, NOT per (target, cert) pair. Cert deploy throughput is operator-grade tens-per-minute; coarse serialization simplifies reasoning about reload-side race windows. Mutexes live for the agent's lifetime — target IDs are bounded so no janitor needed (~16 bytes per entry). Empty TargetID (defensive — should never happen for deploy jobs) bypasses the lock to avoid a singleton serialization point pulling all targetless work onto a shared mutex. Tests (5 named cases in cmd/agent/deploy_mutex_test.go): - TestAgent_ConcurrentDeploysToSameTarget_Serialize — race-detector smoke; 10 goroutines acquire same target's mutex; max-in-flight asserts == 1 - TestAgent_DifferentTargetIDs_ParallelizeIndependently — per-target granularity proof - TestAgent_EmptyTargetID_ReturnsNilMutex — defensive contract - TestAgent_TargetMutex_IsStable — sync.Map LoadOrStore returns same pointer across calls - TestAgent_TargetMutex_RaceLookup — race-free under N=50 concurrent lookups for same key go test -race -count=1 green; gofmt + go vet + golangci-lint v2.11.4 all 0 issues against my new code (pre-existing import-grouping drift in agent_test.go / main.go / verify*.go is unrelated to this change and not caught by `go fmt ./...` which CI uses). Phase 3 next: ValidateOnly method on target.Connector interface; default impl returns ErrValidateOnlyNotSupported across all 13 connectors. |

feat(deploy): atomic write + validate + rollback primitive shared across all target connectors
Phase 1 of the deploy-hardening I master bundle. Closes the load-bearing prerequisite for the seven Bundle I items by extracting one canonical atomic-deploy primitive at internal/deploy/ that all 13 target connectors will consume in Phases 4-9. The package ships: - Plan + Apply API: write all File entries to sibling .certctl-tmp.<nanos> in the destination directory (same-filesystem guarantees os.Rename atomicity), call PreCommit (validate-with-the-target), atomic-rename all temps to final, call PostCommit (reload). On PostCommit failure, restore from pre-deploy backups + re-call PostCommit. If second PostCommit also fails, return ErrRollbackFailed (operator-actionable; documented loud). - AtomicWriteFile lower-level entry for connectors that don't fit the Plan model (F5, K8s — they ship bytes through APIs, not local files). - SHA-256 idempotency: every Apply short-circuits when all File destinations already match SHA-256 of new bytes. Defends against agent-restart retry storms hammering targets with no-op reloads. - Ownership + mode preservation: existing nginx:nginx 0640 stays nginx:nginx 0640 across renewals. Per-target FileDefaults applies for first-deploy. Per-File explicit Mode/Owner/Group overrides win over both. Closes the silent-failure mode where os.WriteFile(path, bytes, 0600) at apache.go:119 (et al.) clobbered worker access. - Backup retention janitor: pre-deploy backup at <path>.certctl-bak.<nanos>; default keeps last 3 (DefaultBackupRetention); BackupRetention=-1 disables backups (rollback impossible — documented foot-gun). - File-level mutex via sync.Map: two concurrent Apply calls touching the same destination serialize. Per-target serialization (Phase 2) is finer- grained at the agent dispatch layer; this is the file-level guard. - Sentinel errors for connector errors.Is checks: ErrPlanInvalid, ErrValidateFailed, ErrReloadFailed, ErrRollbackFailed. Tests (37 named cases across deploy_test.go + coverage_test.go) pin every load-bearing invariant the prompt's Phase 1 requires, plus error-leg coverage uplifts: - TestApply_HappyPath_PreCommitSucceeds_PostCommitSucceeds_FilesAtomic - TestApply_PreCommitFails_NoFilesChanged (atomic-or-nothing on validate) - TestApply_PostCommitFails_FilesRolledBack (rollback wire) - TestApply_RollbackAlsoFails_ReturnsErrRollbackFailed (escalation path) - TestApply_IdempotentSkip_SHA256Match (idempotency short-circuit) - TestApply_PreservesExistingOwnerAndMode_WhenNotOverridden - TestApply_RespectsOverrides_OwnerGroupMode - TestApply_ConcurrentApplyToSameFile_Serializes (file-level lock) - TestApply_BackupRetention_KeepsLastN (janitor pruning) - TestApply_NoExistingFile_UsesDefaultsForOwnerGroupMode - TestAtomicWriteFile_TempFileCleanedUpOnError - TestAtomicWriteFile_RenameRaceWithReader_AtomicReadAlwaysSeesOldOrNew (POSIX-rename atomicity proof via concurrent reader) Plus white-box tests for resolveOwnership, lookupUID/GID, and deeper error legs in restoreFromBackups + applyOwnership + AtomicWriteFile. Coverage 87.3% — practical ceiling without injecting a fault-aware FS abstraction (Write/Sync/Close OS errors are unreachable from go test without sudo'd disk-fill or a custom interface seam). Above the existing service-layer 70% floor; Phases 4-9 will lift this further as they exercise the package through real-connector use. Race detector clean; gofmt + go vet + golangci-lint v2.11.4 all 0 issues. The package is the load-bearing prerequisite for Phases 4-9. Phase 2 next: per-target deploy mutex in cmd/agent/main.go.

test(service): coverage uplift for production hardening II + adjacent helpers (R-CI-extended floor)
CI's R-CI-extended coverage gate failed on 2025-04-30: service-layer
coverage was 68.7% vs the 70% floor. The drag was from new files
(internal/service/ocsp_counters.go, ocsp_response_cache.go,
export_audit_actions.go) that shipped without enough direct tests
to keep the package above the floor.
NEW internal/service/ocsp_counters_test.go (4 tests):
- TestOCSPCounters_NewIsZero — fresh counter snapshot is all zero
- TestOCSPCounters_EveryIncTicksItsLabel — table-driven test
pinning every Inc* method to its label string + the no-cross-
bleed invariant. Critical for Phase 8 Prometheus exposer
contract: a typo in either side would silently drop the
counter from /metrics/prometheus.
- TestOCSPCounters_SnapshotIsCopy — mutating the returned map
doesn't affect the underlying counters
- TestOCSPCounters_ConcurrentTicksRace — race-detector smoke
against sync/atomic primitives
NEW internal/service/ocsp_response_cache_real_test.go (10 tests):
- HappyPath_CachesAfterMiss — first fetch live-signs + writes
cache row; second fetch hits cache
- CacheWriteFailureIsNonFatal — putErrorRepo simulates disk full;
response still returned (fail-soft contract)
- StaleEntryRegenerates — entries with next_update in the past
trigger re-sign on next fetch
- InvalidateOnRevoke — pin the load-bearing security wire
- InvalidateOnRevoke_DeleteFailureSurfacesError — error-path
coverage for the delete branch
- CountByIssuer + NilRepoReturnsEmpty
- CAOperationsSvc.GetOCSPResponseWithNonce_CacheDispatchHit pins
the nil-nonce → cache dispatch wire
- CAOperationsSvc.GetOCSPResponseWithNonce_NonceBypassesCache
pins the nonce-bearing → live-sign bypass wire (cache stays
empty)
- RevocationSvc.SetOCSPCacheInvalidator_WireConnects pins the
setter through to the wired interface
NEW internal/service/coverage_extras_test.go (~12 tests) targets the
0%-coverage chunks adjacent to the bundle's modified files so the
package as a whole stays above the floor:
- cert-export typed audit emission (Phase 7) round-trip with
detail-map inspection (has_private_key + actor_kind + cipher pin)
- PKCS12CipherModernAES256 pinned-value test (drift catches a
future go-pkcs12 default change)
- audit.ListAuditEvents + GetAuditEvent (handler-interface methods
that were at 0%)
- certificate.ListCertificatesWithFilter (M20 filter delegate)
- discovery.{ListScans,GetScan,GetDiscoverySummary} (delegates)
- health_check.{Update,SetNotificationService} delegates + audit
- est.{deterministicSerial,zeroizeBytes,zeroizeKey} pure helpers
+ the live RSA + ECDSA key-zeroize branches
Sandbox total: 67.6% → 69.9% (+2.3pp). The live keygen branches
in zeroizeKey skip in the sandbox when crypto/rand isn't available
but run on CI, so the CI total should land above the 70% floor with
a small buffer.
Pre-commit verification: go build ./... clean; go test -short
-count=1 green for ./internal/service/.

docs(README): expand Standards & Revocation table with production hardening II surfaces
Surfaces the eight items shipped in the post-2026-04-30 production
hardening II bundle on the README's Supported Integrations →
Standards & Revocation table so procurement teams comparing
checklists see them without diving into docs/.
Updates to the existing rows:
- DER-encoded X.509 CRL: now also calls out RFC 7232 caching
headers (ETag + If-None-Match 304 short-circuit)
- Embedded OCSP responder: now also calls out RFC 6960 §4.4.1
nonce echo + the empty/oversized rejection
- S/MIME: spelled out the adaptive KeyUsage delta vs TLS default
- Certificate export: spelled out the cipher (AES-256-CBC PBE2
SHA-256 KDF) + V2 cert-only design rationale
NEW rows:
- CRL DistributionPoints auto-injection (RFC 5280 §4.2.1.13)
- OCSP pre-signed response cache (with the load-bearing
InvalidateOnRevoke wire called out)
- Per-endpoint rate limits (OCSP + cert-export)
- Cert-export typed audit (with cipher pin)
- Prometheus per-area metrics (certctl_ocsp_counter_total)
- Disaster-recovery runbook (docs/disaster-recovery.md, the SOC 2
/ PCI procurement deliverable)
G-3 docs-drift CI guard reproduced clean (every CERTCTL_* env var
mention maps back to internal/config/config.go). S-1 stale-counts
prose guard clean (no literal-number prose for current-state
counts; the rate-limit defaults are config-default values, not
source-derived counts that drift).

fix(cert-export): satisfy staticcheck ST1022 on PKCS12CipherModernAES256
Production hardening II Phase 11 verification — golangci-lint v2.11.4 flagged the const PKCS12CipherModernAES256 doc comment with ST1022 (comments on exported identifiers should start with the identifier name). Reformatted to lead with the const name; same content. Reproduced clean: 0 issues across handler/, service/, connector/issuer/local/, api/router/, ratelimit/. |

docs: production hardening II — DR runbook + crl-ocsp updates + features.md env vars (Phase 10)
Production hardening II Phase 10 — operator-facing documentation
that codifies the new V2 surfaces shipped in Phases 1-8.
NEW docs/disaster-recovery.md (8 sections, ~280 lines):
- Overview of automatic fail-safes already in code
- CRL cache recovery (delete row + scheduler regenerates)
- OCSP responder cert recovery (delete row + ensureOCSPResponder
re-bootstraps on next request)
- OCSP response cache recovery (delete row + read-through fallback)
- CA private-key rotation procedure (9-step playbook)
- Postgres restore (with explicit list of operator-managed
artifacts NOT in DB)
- Trust-bundle reload semantics (SCEP / EST / Intune SIGHUP-
equivalent fail-safe behavior)
- DR checklist (printable; pin near on-call)
This is the SOC 2 / PCI procurement-team deliverable. Auditors and
on-call operators get a single document that tells them what to do
when state corrupts, when keys need rotation, when Postgres needs
restoring. Nothing in the runbook requires new code — it codifies
behaviors already in the codebase.
UPDATED docs/crl-ocsp.md:
- New "Production hardening II additions" section: OCSP nonce
extension, OCSP pre-signed cache (with the load-bearing security
wire called out), per-source-IP OCSP rate limit, per-actor cert-
export rate limit, CRL HTTP caching headers (RFC 7232), CRL
DistributionPoints auto-injection, cert-export typed audit
codes, per-area Prometheus metrics with operator alert
recommendations.
- Pruned the V3-Pro deferral list to remove items that this
bundle SHIPPED (OCSP rate-limiting moved out; remaining V3-Pro:
delta CRLs, OCSP stapling, OCSP request signature verification,
HA / multi-region replication, IDP extension for sharded CRLs).
UPDATED docs/features.md:
- CERTCTL_OCSP_RATE_LIMIT_PER_IP_MIN row (default 1000)
- CERTCTL_CERT_EXPORT_RATE_LIMIT_PER_ACTOR_HR row (default 50)
G-3 docs-drift CI guard reproduced clean: every new CERTCTL_* env
var documented in features.md AND consumed in Go source. S-1 stale-
counts guard clean (no literal-number prose for current-state
counts in README/docs).

feat(metrics): extend /metrics/prometheus with per-area OCSP counters (Phase 8)
Production hardening II Phase 8 — surface the OCSP per-event counters
shipped in Phase 1+2 through the existing /api/v1/metrics/prometheus
endpoint. Operators now alert on certctl_ocsp_counter_total
{label="rate_limited"} (Phase 3 trip), {label="nonce_malformed"}
(Phase 1 reject), {label="signing_failed"} (issuer connector fails),
etc.
NEW interface CounterSnapshotter (handler/metrics.go) — minimum
surface the Prometheus exposer needs from any per-area counter table:
just Snapshot() map[string]uint64. service.OCSPCounters.Snapshot
(Phase 1) satisfies it; future per-area counters (CRL, cert-export,
EST per-profile, SCEP per-profile, Intune per-profile) plug in the
same way as separate SetXxxCounters setters.
Naming convention per frozen decision 0.10:
certctl_<area>_counter_total{label="<event>"} <value>
This commit ships only the OCSP block. The remaining areas (CRL,
cert-export, EST, SCEP, Intune) plug in via the same
SetXxxCounters pattern in follow-up commits — the wire-up cost per
area is one new field + one setter + one block of fmt.Fprintf lines.
The bundle's S-1 docs-count guard means we don't claim a specific
total in prose; operators run `curl /api/v1/metrics/prometheus | grep
certctl_` to enumerate.
Wired in cmd/server/main.go: a single shared *service.OCSPCounters
instance is created once and passed to BOTH the
ocspResponseCacheService (so the cache hot path ticks counters) AND
metricsHandler.SetOCSPCounters (so the Prometheus exposer reads
them). Existing dashboard metrics (certctl_certificate_total,
certctl_agent_total, etc.) remain unchanged at the same line offsets
— back-compat preserved.
Pre-commit verification: go build ./... clean; go test -short
-count=1 green for handler/ + service/. The existing
TestGetPrometheusMetrics_Success tests still pass (the new counter
block is additive at the END of the response body, after the
existing dashboard metrics + uptime line).

feat(cert-export): typed audit-action constants + has_private_key + cipher detail (Phase 7)
Production hardening II Phase 7 — typify the cert-export audit
emission. The pre-Phase-7 audit log carried inline strings
("export_pem" / "export_pkcs12"); this commit adds typed
constants alongside via the split-emit pattern so operators get
both back-compat with existing log analysers AND a stable typed
grep target.
NEW internal/service/export_audit_actions.go:
- AuditActionCertExportPEM = "cert_export_pem"
- AuditActionCertExportPEMWithKey = "cert_export_pem_with_key"
(reserved for future bundle that adds key-bearing export; not
emitted in V2)
- AuditActionCertExportPKCS12 = "cert_export_pkcs12"
- AuditActionCertExportFailed = "cert_export_failed"
- PKCS12CipherModernAES256 = "AES-256-CBC-PBE2-SHA256" pinned
string for the cipher detail (drift catches a future go-pkcs12
default change)
Detail enrichment on both emission sites:
- has_private_key (bool, V2 always false — cert-only export is

- actor_kind ("user")
- cipher (PKCS12 only — pinned to PKCS12CipherModernAES256)
Split-emit pattern: each export emits BOTH the legacy bare action
code AND the typed constant. Mirrors est.go::processEnrollment which
emits both "est_simple_enroll" + "est_simple_enroll_success".
Existing audit-log analysers that match by exact string "export_pem"
keep working; new operator alerts can target the typed constant.

feat(local-issuer): RFC 5280 §4.2.1.13 CRLDistributionPoints auto-injection (Phase 6)
Production hardening II Phase 6 — close the operator-must-manually- configure-CDP gap that the EST hardening prompt's deferral list flagged. When the local issuer has CRLDistributionPointURLs configured, every issued cert carries the id-ce-cRLDistributionPoints extension pointing at the configured URLs. Relying parties (browsers, OpenSSL, cert-manager) read the CDP and fetch the CRL automatically; without this extension, operators have to ship the CRL endpoint URL out-of- band. NEW Config field internal/connector/issuer/local/local.go:: Config.CRLDistributionPointURLs []string. Empty (default) preserves pre-Phase-6 behavior — no CDP extension. Refusing to silently inject an empty CDP is frozen decision 0.9 from the production hardening II prompt: a cert with an empty CDP extension fails relying-party validation worse than a cert with no CDP at all. Issuer wire: generateCertificate appends the configured URLs to template.CRLDistributionPoints. crypto/x509 handles the ASN.1 encoding (RFC 5280 §4.2.1.13) — no manual marshaling needed. Operator config (cmd/server/main.go wire-up to follow when the operator opts in via per-issuer config-blob fields; the local issuer's existing dynamic-config-via-GUI path picks up the new field via the standard JSON unmarshal). Typical value: ["https://certctl.example.com:8443/.well-known/pki/crl/iss-local"] Pre-commit verification: go build ./... clean; go test -short -count=1 green for connector/issuer/local/. |

feat(crl): HTTP caching headers (ETag + If-None-Match 304) per RFC 7232 (Phase 4)
Production hardening II Phase 4 — wire RFC 7232 conditional-request support into GetDERCRL so CDNs and reverse proxies in front of certctl can serve repeated CRL fetches from edge caches. Saves bandwidth + removes the per-request DB read on the certctl side when a relying party honors max-age. ETag: weak form (W/) per RFC 7232 §2.3 wrapping the first 16 bytes of SHA-256(DER) — sufficient ID space for the cache layer + leaves headroom for a future builder that might emit signature randomness that doesn't change the CRL semantics. If-None-Match: when the inbound header matches the computed ETag, short-circuit to 304 Not Modified with no body. Identical inbound ETag → identical CRL → no need to retransmit the bytes. Cache-Control: public, max-age=3600, must-revalidate. The 1h max-age matches the default CRL regen cadence; relying parties that cache won't re-fetch within the window. must-revalidate forces revalidation once the window expires (so a stale relying party doesn't keep returning expired-cache CRLs after the regen tick). The pre-existing Cache-Control: max-age=3600 is preserved syntactically (the new line replaces it with the more complete form); existing relying parties see the same ceiling, just with the addition of public + must-revalidate hints for downstream caches. Pre-commit verification: go build ./... clean; go test -short -count=1 green for handler/. The existing TestGetDERCRL_* tests still pass — the new headers are additive, the response body is unchanged. |

feat(ratelimit): per-endpoint rate limit on OCSP + cert-export (Phase 3)
Production hardening II Phase 3 — wire the existing
internal/ratelimit/SlidingWindowLimiter into the OCSP and cert-export
handlers. Removes the DoS vector where an unauthenticated relying
party (or compromised admin token) can hammer the responder /
key-export endpoint at unbounded rates.
OCSP: per-source-IP cap. Default 1000 req/min/IP, 50k tracked IPs
(matches the SCEP/Intune replay cache cap). Configurable via
CERTCTL_OCSP_RATE_LIMIT_PER_IP_MIN; zero disables. Source IP comes
from net.SplitHostPort(r.RemoteAddr) — we deliberately do NOT honor
X-Forwarded-For because OCSP is publicly reachable and untrusted
intermediaries could spoof the header to bypass the limit.
On rate-limit trip: respond with the canonical
ocsp.UnauthorizedErrorResponse pre-built blob from x/crypto/ocsp
(status 6 per RFC 6960 §2.3) plus Retry-After: 60. Using the
unauthorized status (instead of TryLater) avoids hand-rolling DER
for a single rejection path; relying parties retry on any non-good
status anyway.
Cert-export: per-actor cap. Default 50 exports/hr/operator.
Configurable via CERTCTL_CERT_EXPORT_RATE_LIMIT_PER_ACTOR_HR; zero
disables. Actor extracted from the X-Actor request header (set by
the auth middleware); falls back to RemoteAddr if empty (defensive).
On rate-limit trip: HTTP 429 + JSON body
{"error":"rate_limit_exceeded","retry_after_seconds":3600} +
Retry-After: 3600.
NEW config fields in internal/config/config.go::SchedulerConfig:
OCSPRateLimitPerIPMin (default 1000)
CertExportRateLimitPerActorHr (default 50)
WIRED in cmd/server/main.go: ocspLimiter constructed with the
configured cap, 1m window, 50k map cap; exportLimiter same shape with
1h window. Both wired via SetOCSPRateLimiter / SetExportRateLimiter
on their respective handlers. Existing deploys see no behavior
change unless the env vars are set to non-default values + traffic
exceeds the cap.

feat(ocsp): pre-signed response cache + invalidate-on-revoke (Phase 2)
Production hardening II Phase 2 — closes the per-request live-signing
bottleneck for OCSP. Mirrors the existing crl_cache pattern (migration
000019 / internal/service/crl_cache.go) but per (issuer_id, serial_hex)
instead of per-issuer.
LOAD-BEARING SECURITY INVARIANT: a revoked cert MUST NOT continue to
return the stale 'good' cached response after revocation. The
RevocationSvc.RevokeCertificateWithActor flow now calls
OCSPResponseCacheService.InvalidateOnRevoke after a successful revoke
so the next OCSP fetch falls through to live signing and returns the
revoked status. Pinned by TestOCSPCache_InvalidateOnRevoke_NextFetchReturnsRevoked.
NEW migrations/000024_ocsp_response_cache.{up,down}.sql with composite
PK (issuer_id, serial_hex), nullable revocation_reason / revoked_at,
next_update index for the scheduler refresh loop, issuer_id index for
admin observability.
NEW internal/domain/ocsp_response_cache.go::OCSPResponseCacheEntry +
IsStale helper.
NEW internal/repository/postgres/ocsp_response_cache.go implementing
repository.OCSPResponseCacheRepository (Get / Put / Delete /
CountByIssuer). Interface defined in internal/repository/interfaces.go.
NEW internal/service/ocsp_response_cache.go::OCSPResponseCacheService
with read-through facade + sync.Map singleflight + InvalidateOnRevoke.
On cache miss, calls caOperationsSvc.LiveSignOCSPResponse(nil) — the
NEW bypass-cache entry point — to break the cyclic dependency between
cache and CAOps.
REFACTORED internal/service/ca_operations.go:
- GetOCSPResponseWithNonce now dispatches: nil-nonce + cache wired
→ cacheSvc.Get (cache); nonce != nil OR cache nil → live-sign.
- LiveSignOCSPResponse is the new exported bypass-cache entry point;
contains the body of what was previously the GetOCSPResponse-
With-Nonce path.
- SetOCSPCacheSvc + new OCSPResponseCacher interface (cyclic-dep
break + test-injectable).
The cache stores nil-nonce blobs by design. Nonce-bearing requests
always live-sign because re-signing to add a nonce defeats caching;
this is a deliberate tradeoff — most relying parties don't send
nonces (Apple Push, Microsoft Edge SmartScreen, Firefox), and the
minority that do already accept the extra round-trip cost for replay
protection.
WIRED in cmd/server/main.go alongside the existing CRL cache wire:
ocspResponseCacheRepo + ocspResponseCacheService + SetOCSPCacheSvc +
SetOCSPCacheInvalidator. Existing deploys see no behavior change
(cache is consulted but on every cold-start the first fetch lands
through the live-sign + write-back path).
NOT YET WIRED in this commit (deferred to next phase commit to keep
this one shippable):
- Scheduler ocspCacheRefreshLoop (the warm-on-startup + N-hourly
refresh loop). The cache works without it; entries just live-sign
on miss + cache hit thereafter, so cold caches warm up
organically as relying parties query.
- Admin observability endpoint /api/v1/admin/ocsp/cache.
- CERTCTL_OCSP_CACHE_REFRESH_INTERVAL env var.
These three are the visible-but-not-load-bearing wires; the security
invariant (no stale-good-after-revoke) is fully shipped here.
7 new tests in internal/service/ocsp_response_cache_test.go pin every
documented invariant, with TestOCSPCache_InvalidateOnRevoke_NextFetch
ReturnsRevoked called out as the load-bearing security test.
Pre-commit verification: go build ./... clean; go test -short -count=1

feat(ocsp): RFC 6960 §4.4.1 nonce extension support — echo client nonce in response, reject malformed
Production hardening II Phase 1.
The OCSP responder previously ignored the request's nonce extension
entirely, leaving relying parties vulnerable to replay attacks. RFC
6960 §4.4.1 defines the OPTIONAL id-pkix-ocsp-nonce extension (OID
1.3.6.1.5.5.7.48.1.2): when present in the request, the responder
MUST echo the same value in the response; when absent, no nonce in
the response (back-compat with relying parties that don't send one).
NEW internal/service/ocsp_nonce.go: ParseOCSPRequestNonce walks raw
DER (golang.org/x/crypto/ocsp.Request doesn't expose the request's
extensions field — the library only exposes IssuerNameHash +
IssuerKeyHash + SerialNumber). Returns one of three states:
- (nil, false, nil) — no nonce extension in request
- (nonce, true, nil) — well-formed nonce, ≤ MaxOCSPNonceLength (32)
- (nil, false, ErrOCSPNonceMalformed) — empty or oversized
NEW internal/service/ocsp_counters.go: sync/atomic counter table for
OCSP request lifecycle (request_get/post, request_success/invalid,
nonce_echoed, nonce_malformed, rate_limited, ...). Mirrors the EST/
SCEP counter pattern; Phase 8 wires these into /metrics/prometheus.
CertSrv types extended:
- internal/connector/issuer/interface.go::OCSPSignRequest gains
Nonce []byte field.
- internal/service/renewal.go::OCSPSignRequest (the service-layer
duplicate used by ca_operations.go) gains the same field.
- internal/service/issuer_adapter.go bridges the two.
Service path: CAOperationsSvc.GetOCSPResponseWithNonce(ctx, issuerID,
serialHex, nonce) is the new entry point that plumbs the nonce
through every signing site (good / revoked / unknown / short-lived).
The legacy GetOCSPResponse becomes a nil-nonce wrapper for back-
compat — every existing caller (tests, the GET handler) sees no
behavior change.
CertificateService gains the same WithNonce variant; the handler
interface adds it to the contract. MockCertificateService in tests
extended with the new method (delegates to the legacy fn when no
override is set, so existing tests that don't care about the nonce
keep working).
Local issuer's SignOCSPResponse appends the id-pkix-ocsp-nonce
extension (non-Critical per RFC 6960 §4.4) to the response template's
ExtraExtensions when req.Nonce != nil. The extnValue is the nonce
bytes wrapped in an OCTET STRING per RFC 6960 §4.4.1.
POST OCSP handler (HandleOCSPPost):
- After ocsp.ParseRequest succeeds, calls ParseOCSPRequestNonce on
the raw body to extract the optional nonce.
- On ErrOCSPNonceMalformed (empty or > 32 bytes): writes an
'unauthorized' OCSP response (status 6 per RFC 6960 §2.3) using
the canonical ocsp.UnauthorizedErrorResponse from x/crypto/ocsp.
Does NOT echo malicious bytes back.
- On well-formed nonce: passes it through GetOCSPResponseWithNonce.
- On no nonce: nil passed through; back-compat preserved.
GET OCSP handler unchanged — the GET form has no body to carry a
nonce extension.
6 new tests in internal/service/ocsp_nonce_test.go pin every
documented failure mode + the 32-byte boundary. The test fixture
builds an OCSPRequest via golang.org/x/crypto/ocsp.CreateRequest then
splices in a [2] EXPLICIT Extensions element by hand (the library
doesn't expose extension construction either).
Pre-commit verification: gofmt clean, go vet clean across affected
packages, go test -short -count=1 green for service/ + handler/ +
connector/issuer/local/. No new env vars introduced (Phase 1 is
always-on per RFC; no operator opt-out).

fix(README): drop hardcoded source-counts from EST row to satisfy S-1 guard
CI's 'Forbidden hardcoded source-count prose regression guard (S-1)'
fired on the new EST row in README.md:109. The trip was on the literal
'6 MCP tools' phrase — that matches the regex pattern
\b[0-9]+\s+MCP tools\b which the S-1 guard rejects per the CLAUDE.md
rule 'Numeric claims about current state rot.'
Same rule covers the '13 typed audit-action codes' literal earlier on
the same line — the regex doesn't catch that one specifically (no
'audit-action codes' alternation in the guard pattern), but the spirit
of the rule applies, so I removed it preemptively to avoid the next
operator-reads-the-doc-then-edits-the-code-then-the-count-is-wrong
drift cycle.
Replacements:
'13 typed audit-action codes (...)' →
'Typed audit-action codes per failure dimension (... — full set in
internal/service/est_audit_actions.go)'
'CLI + 6 MCP tools' →
'CLI + matching MCP tool family (rebuild count via
grep -cE '"est_' internal/mcp/tools_est.go)'
The rebuild-command form follows the convention CLAUDE.md::Current-state
commands established + the existing docs/features.md row
'MCP tools | rebuild via grep -cE 'gomcp\.AddTool\(' ...'
Verified locally with the exact CI guard regex against README.md +
docs/ — 'S-1 stale-counts guardrail: clean.'
The 'All six RFC 7030 endpoints' phrasing earlier on the same line
is NOT a current-state count — six is fixed by RFC 7030 (cacerts +
simpleenroll + simplereenroll + csrattrs + serverkeygen + fullcmc),
not derived from source. The S-1 regex requires \b[0-9]+ literal
digits, so 'six' as a word doesn't match anyway.

docs(est): EST RFC 7030 operator guide + WiFi/802.1X recipe + IoT bootstrap recipe + FreeRADIUS integration + architecture + README
EST RFC 7030 hardening master bundle Phase 12 — comprehensive operator- facing documentation for the Phases 1-11 backend work that shipped on 2026-04-29. NEW docs/est.md (19 sections, ~810 lines): Concepts (host vs user enrollment, profile-driven policy, multi-profile dispatch); 5-minute single-profile Quick start with curl + openssl recipes; Multi-profile dispatch (CERTCTL_EST_PROFILES=corp,iot,wifi setup with PathID rules enforced at boot); Authentication modes (mTLS / Basic / both / empty with cross-check semantics); RFC 9266 channel binding (failure-mode HTTP mapping table — ErrChannelBindingMissing/Mismatch/NotTLS13 → 400/409/426); WiFi/802.1X recipe with end-to-end FreeRADIUS integration (EAP-TLS supplicant config, mods-available/eap tls-common block, CRL distribution endpoint cross-ref, troubleshooting playbook); IoT bootstrap recipe (factory provisioning, first boot, steady-state renewal, compromise/decommission via bulk-revoke, recommended cert lifetimes per master prompt §7.7); serverkeygen for resource-constrained devices (CMS EnvelopedData wrap, RSA-only at this revision, zeroize discipline, Phase-1 cross-check refusing _SERVERKEYGEN_ENABLED=true with empty _PROFILE_ID); HSM-backed CA signing for EST cross-ref (signer interface seam); Operator GUI tabbed surface tour (/est: Profiles / Recent Activity / Trust Bundle); CLI + 6 MCP tools; Renewal device-driven model (RFC 7030 §4.2.2 mandate, renewal-trigger ratios for laptops/IoT, operator-push via webhook); Troubleshooting matrix (one row per typed audit-action constant in internal/service/est_audit_actions.go); TLS 1.2 reverse-proxy runbook cross-ref (channel-binding caveat explained); Threat model (load-bearing properties: trust-anchor reload fail-safety, per-profile counter isolation, mTLS cross-profile bleed defense, source-IP limiter process-locality, server-keygen heap residency, HTTP Basic in-process-only, legacy-anonymous-default back-compat carve-out); V3-Pro deferrals; Appendix A (libest sidecar reproducer + 5 integration test names); Appendix B (Cisco IOS 15.x + 16.x + Apple MDM + OpenWRT + libest <v3.0 wire-format quirks tested in internal/api/handler/cisco_ios_quirks_test.go). UPDATED docs/architecture.md: new "EST Server (RFC 7030) — Production Deployment" section under the existing baseline EST section. Mermaid diagram of multi-profile dispatch + mTLS sibling route + per-profile gate ordering + audit + GUI + SIGHUP-equivalent reload. Existing authentication paragraph updated with forward-ref to the hardening section. Audit paragraph updated to enumerate the 13 typed est_* action codes operators grep on. Trust-anchor reload semantics + libest interop tested in CI both called out. UPDATED README.md::Enrollment Protocols: replaced the one-line EST row with the full production-grade surface description matching the SCEP analog. Cross-references docs/est.md. UPDATED docs/connectors.md::EST/SCEP Integration: extended the EST-or-SCEP shared paragraph to point at the per-profile env-var form for both protocols + linked the new architecture.md section. NEW "Multi-profile EST dispatch + production hardening" subsection mirrors the SCEP equivalent: 9-row env-var table, cross-ref to docs/est.md. G-3 docs-drift CI guard reproduced locally clean — every CERTCTL_EST_* mention in docs maps back to internal/config/config.go, and every defined env var is documented. The `<NAME>` placeholder convention matches the SCEP idiom so the docs grep doesn't extract per-deploy profile names as phantom env vars. No new env vars introduced — this is a pure docs commit. |

fix(deploy/libest): pin debian:bookworm-slim FROM lines to digest (H-001)
CI's 'Forbidden bare FROM regression guard (H-001)' rejects any Dockerfile FROM line missing an @sha256:... digest pin. The Phase 10 libest sidecar Dockerfile shipped two bare FROMs at lines 25 and 55, both targeting debian:bookworm-slim. The repo's Bundle A / Audit H-001 (CWE-829) policy has been in force on every other Dockerfile since the bundle landed; the new sidecar simply needs to follow the same convention. Pinned both lines to: debian:bookworm-slim@sha256:f9c6a2fd2ddbc23e336b6257a5245e31f996953ef06cd13a59fa0a1df2d5c252 That's the OCI image-index digest from https://hub.docker.com/v2/repositories/library/debian/tags/bookworm-slim fetched 2026-04-29 (last_pushed 2026-04-22). Multi-arch index, so Docker resolves the per-arch manifest correctly on the CI runner. Added a comment at the top of the FROM block documenting the bump procedure (curl + jq one-liner against the Docker Hub registry API), matching the convention from the top-level Dockerfile. Verified locally with the exact CI guard regex (grep -HnE '^FROM\s+[^@#]+(\s+AS\s+\S+)?\s*$' across every Dockerfile* under the repo, excluding web/node_modules) — passes. Also verified the M-012 USER-drop guard still passes for the libest sidecar (terminal USER estuser, set on line 73). |

fix(est): plumb context through ESTService.ReloadTrust to satisfy contextcheck
CI golangci-lint v2.11.4 flagged internal/api/handler/admin_est.go:178: the AdminESTServiceImpl.ReloadTrust method took ctx context.Context but called svc.ReloadTrust() with no context, then the underlying ESTService.ReloadTrust used context.Background() internally for the audit RecordEvent call. That's the contextcheck linter's textbook 'context discarded at boundary' violation. Fix: change ESTService.ReloadTrust signature to ReloadTrust(ctx context.Context) and forward the caller-supplied ctx into auditService.RecordEvent. AdminESTServiceImpl.ReloadTrust now passes its received ctx through. The HTTP handler already forwards r.Context() one layer up, so the request-scoped trace identifiers now flow end-to-end into the audit row instead of being severed at the service boundary. Verified locally with golangci-lint v2.11.4 (the same version CI runs) against ./internal/api/handler/... ./internal/service/... — '0 issues.' All cmd/* binaries build clean, go test -short -count=1 green for both packages. |

EST RFC 7030 hardening master bundle Phases 10-11: libest sidecar e2e
+ Cisco IOS quirk fixtures + ManagedCertificate.Source provenance + EST bulk-revoke endpoint + 13 typed audit action codes. Phase 10.1 — libest reference-client sidecar: - deploy/test/libest/Dockerfile: multi-stage Debian-bookworm-slim build of Cisco's libest v3.2.0-2 from source (autoconf/automake/ libtool + libcurl4-openssl-dev + libssl-dev). Runtime stage carries only estclient + bash + openssl + ca-certificates so the exec surface stays small + predictable. - docker-compose.test.yml libest-client entry (profiles: [est-e2e]) with bind mounts for /config/est (test workspace) + /config/certs (certctl CA bundle for TLS pinning); IP 10.30.50.9 (10.30.50.8 was already taken by certctl-agent). - deploy/test/est/.gitkeep keeps the bind-mount target tracked. Phase 10.2 — 5 integration tests (//go:build integration) in deploy/test/est_e2e_test.go: - TestEST_LibESTClient_Enrollment_Integration (cacerts → simpleenroll → cert-shape assertion) - TestEST_LibESTClient_MTLSEnrollment_Integration (mTLS sibling-route cert auth; skip when bootstrap cert absent) - TestEST_LibESTClient_ServerKeygen_Integration (RFC 7030 §4.4 multipart; skip when profile gate disabled) - TestEST_LibESTClient_RateLimited_Integration (4th enroll trips per-principal cap, asserts 429-shaped error) - TestEST_LibESTClient_ChannelBinding_Integration (libest --tls-exporter; skip when libest build lacks the flag). - requireESTSidecar guard skips the suite when the operator forgot --profile est-e2e; helpful error message includes the exact command to bring the sidecar up. Phase 10.3 — Cisco IOS quirk fixtures + 3 unit tests in internal/api/handler/cisco_ios_quirks_test.go: - testdata/cisco_ios_15x_pem_csr.txt: PEM body sent with Content-Type application/x-pem-file. Handler dispatches on body-prefix not Content-Type — accepts cleanly. - testdata/cisco_ios_16x_trailing_newline_csr.txt: extra trailing newlines after base64 body. strings.TrimSpace tolerates. - testdata/cisco_ios_crlf_b64_csr.txt: CRLF-wrapped base64. base64.StdEncoding handles CRLF + LF identically. Phase 11.1 — ManagedCertificate.Source provenance: - New domain.CertificateSource enum (Unspecified/EST/SCEP/API/Agent). - Migration 000023_managed_certificates_source.up.sql adds source TEXT NOT NULL DEFAULT '' so existing rows scan as CertificateSourceUnspecified — back-compat: bulk-revoke filter treats empty as "any source". - Postgres repo Insert/Update/scan paths all wire the new column. Phase 11.2 — EST bulk-revoke endpoint: - BulkRevocationCriteria.Source field (Source-only requests rejected as too broad — must accompany at least one narrower criterion). - service.bulk_revocation.resolveCertificates post-filter by Source (empty=any, no SQL change so existing CertificateFilter callers unaffected). - New BulkRevocationHandler.BulkRevokeEST method pins Source=EST + dispatches; new route POST /api/v1/est/certificates/bulk-revoke (M-008 admin-gated). openapi.yaml documented + parity-guard green. Phase 11.3 — 13 typed audit action codes in internal/service/est_audit_actions.go: - est_simple_enroll_success / _failed - est_simple_reenroll_success / _failed - est_server_keygen_success / _failed - est_auth_failed_basic / _mtls / _channel_binding - est_rate_limited - est_csr_policy_violation - est_bulk_revoke - est_trust_anchor_reloaded - ESTService.processEnrollment + SimpleServerKeygen + ReloadTrust split-emit BOTH the legacy bare action codes (back-compat for the GUI activity-tab chip filters that match by exact string + existing audit-log analysers) AND the new typed _success / _failed variants (operator grep target + per-failure-mode counter). Tests: - internal/api/handler/bulk_revocation_est_test.go — 5 cases (admin-true happy path pins Source=EST + non-admin 403 + empty-criteria 400 + invalid-reason 400 + method-not-allowed). - internal/service/est_audit_actions_test.go — 5 cases (SimpleEnroll legacy+typed emission / SimpleReEnroll typed / IssuerError typed-failed / PolicyViolation triple-emit / unique-string invariant). Pre-commit verification (sandbox): gofmt clean, go vet clean (excluding repository/postgres testcontainers limit), staticcheck clean across api/handler/api/router/domain/service/deploy/test, go test -short -count=1 green for every non-postgres Go package + integration build (`go build -tags integration ./deploy/test/...`) clean. G-3 docs-drift guard reproduced locally clean (Phases 10-11 added zero new env vars). Spec preserved at cowork/est-rfc7030-hardening-prompt.md. Phases 12-13 (docs/est.md + WiFi/802.1X / IoT bootstrap / FreeRADIUS recipes; release prep + tag) remain — post-2.1.0 work. |

EST RFC 7030 hardening master bundle Phases 8-9: GUI ESTAdminPage
(Profiles + Recent Activity + Trust Bundle tabs) + CLI subcommand
family `certctl-cli est {cacerts,csrattrs,enroll,reenroll,
serverkeygen,test}` + 6 MCP tools.
Phase 8 — ESTAdminPage tabbed GUI:
- web/src/pages/ESTAdminPage.tsx mirrors SCEPAdminPage's three-tab
surface. Profiles tab renders per-profile cards with auth-mode
badges (mTLS / Basic / ServerKeygen), mTLS trust-anchor expiry
countdown (good ≥30d / warn 7-30d / bad <7d / EXPIRED), 12-cell
counter grid (success_simpleenroll/.../internal_error), and the
admin-gated "Reload trust anchor" action. Recent Activity tab
merges the four EST audit actions (est_simple_enroll +
est_simple_reenroll + est_server_keygen + est_auth_failed) across
four parallel useQuery calls with chip filters for All/Enrollment/
Re-enrollment/ServerKeygen/AuthFailure. Trust Bundle tab renders
per-mTLS-profile cert subjects + expiries.
- M-009 useTrackedMutation guard: every mutation routes through
the tracked hook so audit/progress hooks fire.
- Page-level admin gate renders "Admin access required" banner for
non-admin callers + skips underlying API requests so the server
never sees a 403-prone request. Server-side enforcement is the
M-008 admin gate; this is a UX hint.
- Wired into web/src/main.tsx at /est; nav link added to Layout.tsx.
- New web/src/api/types.ts types ESTStatsSnapshot +
ESTTrustAnchorInfo + ESTProfilesResponse + ESTReloadTrustResponse
mirror service.ESTStatsSnapshot 1:1.
- New web/src/api/client.ts helpers getAdminESTProfiles +
reloadAdminESTTrust.
- 14 Vitest cases (admin gate non-admin / non-auth-required deploy /
default tab / tab switch / deep-link tab / per-profile card render
+ counter cells / reload-button mTLS-only / trust-expiry badge
band / reload modal Confirm-Cancel-Error paths / Trust Bundle
empty-state / Activity filter chip toggle).
Phase 9.1 — CLI subcommands:
- internal/cli/est.go adds 6 subcommands: cacerts / csrattrs /
enroll / reenroll / serverkeygen / test. CSR input via --csr
with file-path or '-' for stdin; multipart serverkeygen response
is parsed by stdlib mime/multipart and split into <prefix>.cert.pem
+ <prefix>.key.enveloped so the operator can decrypt the key with
openssl smime. EST `test` smoke-tests cacerts + csrattrs + emits
one-line OK/FAIL diagnostics.
- cmd/cli/main.go grows the `est` dispatch + Usage entries.
Phase 9.2 — MCP tools:
- internal/mcp/tools_est.go adds 6 tools mapped to the EST endpoints
+ admin observability: est_list_profiles + est_admin_stats (alias)
+ est_get_cacerts + est_get_csrattrs + est_enroll + est_reenroll.
Tool count grew from 87 → 93 (verified via the registered-vs-
covered guard in tools_per_tool_test.go); the per-tool happy/error-
path table grew with 6 matching entries so the future-tool-no-test
CI guard stays green.
- internal/mcp/client.go grows PostRaw — non-JSON POST helper that
the EST enroll/reenroll tools use to ship raw application/pkcs10
CSR bytes through the MCP fence-wrapped response.
- estRawResultJSON wraps the raw response body in a JSON envelope
the MCP consumer can structurally consume (content_type +
body_base64 + body_size_bytes). Mirrors the CRL/OCSP MCP tools'
binary-DER envelope.
Phase 9.3 — Tests:
- internal/cli/est_test.go: 8 cases pinning the wire-shape contract
on the CLI side without dragging the full ESTHandler into the
test build.
- internal/mcp/tools_est_test.go: path-builder + JSON-envelope unit
tests + end-to-end tool exercise that pins all 5 captured request
paths through a fake API.
Pre-commit verification (sandbox): gofmt clean, go vet clean
(excluding repository/postgres which the sandbox can't build —
pre-existing testcontainers limit), staticcheck clean across
cli/mcp/cmd/cli, go test -short -count=1 green for every non-
postgres Go package, Vitest green for ESTAdminPage (14) +
SCEPAdminPage (20) — 34 page tests total. G-3 docs-drift guard
reproduced locally clean (Phases 8-9 added zero new env vars).
Spec preserved at cowork/est-rfc7030-hardening-prompt.md. Phases
10-13 (libest sidecar e2e / bulk revocation + audit codes /
docs/est.md / release prep + tag) remain — post-2.1.0 work.

EST RFC 7030 hardening master bundle Phases 5-7: end-to-end serverkeygen
+ profile-driven csrattrs + admin observability with per-status counters + reload-trust endpoint. Phase 5 — RFC 7030 §4.4 server-driven key generation: - internal/pkcs7/envelopeddata_builder.go is the inverse of the existing parser/decryptor: AES-256-CBC content cipher + RSA PKCS#1 v1.5 keyTrans + per-call random IV. Round-trip pinned in test (BuildEnvelopedData → ParseEnvelopedData → Decrypt returns the original plaintext byte-for-byte). - ESTService.SimpleServerKeygen runs the full §4.4 flow: parse client CSR → require RSA pubkey for keyTrans → resolve per-profile algorithm (RSA-2048 default; honors AllowedKeyAlgorithms) → in- memory keygen → re-build CSR with server pubkey → run existing issuer pipeline → marshal PKCS#8 → CMS-EnvelopedData wrap to a synthetic recipient cert wrapping the device's CSR-supplied pubkey → zeroize plaintext + PKCS#8 bytes → return CertPEM + ChainPEM + EncryptedKey. Typed sentinels ErrServerKeygenRequiresKey- Encipherment / ErrServerKeygenUnsupportedAlgorithm / ErrServerKeygenDisabled. - ESTHandler.ServerKeygen + ServerKeygenMTLS emit RFC 7030 §4.4.2 multipart/mixed with random per-response boundary; per-profile SetServerKeygenEnabled gate returns 404 when off (defense in depth even if the route was registered). - New routes POST /.well-known/est/[<PathID>/]serverkeygen + /.well-known/est-mtls/<PathID>/serverkeygen; openapi.yaml + openapi-parity guard updated. Phase 6 — Real csrattrs implementation: - New CertificateProfile.RequiredCSRAttributes []string + migration 000022_certificate_profiles_csrattrs.up.sql. The migration also lands the previously-unwired must_staple column (closes the 5.6 follow-up loop where the field shipped at the domain + service layer but the postgres scan/insert/update never persisted it). - domain.EKUStringToOID + AttributeStringToOID lookup tables: id-kp-* EKUs (RFC 5280 §4.2.1.12) + RFC 5280 DN attributes + RFC 2985 PKCS#10 attributes + Microsoft Intune device-serial OID. - ESTService.GetCSRAttrs replaces the v2.0.x nil/204 stub with a profile-derived SEQUENCE OF OID ASN.1 marshal. Unknown EKU / attribute strings dropped + warning-logged so a typo doesn't take down the entire endpoint. Phase 7 — Admin observability + counters + reload-trust: - internal/service/est_counters.go: estCounterTab (sync/atomic; 12 named labels) + ESTStatsSnapshot per-profile shape + ESTService.Stats(now) zero-allocation accessor + ReloadTrust() SIGHUP-equivalent + SetESTAdminMetadata setter. - Counter ticks wired into processEnrollment + SimpleServerKeygen at every success/failure leg. - internal/api/handler/admin_est.go mirrors AdminSCEPIntune verbatim: Profiles + ReloadTrust handlers + AdminESTServiceImpl. Both endpoints admin-gated (M-008 triplet pinned + admin_est.go added to AdminGatedHandlers). - New routes GET /api/v1/admin/est/profiles + POST /api/v1/admin/ est/reload-trust; openapi.yaml documented; openapi-parity guard reproduced clean. - cmd/server/main.go grows estServices map populated by the per- profile EST loop + handed to AdminEST. New MTLSTrust() + HasMTLSTrust() accessors on ESTHandler so main.go can pull the trust holder for the admin-metadata wire-up. - Per-profile counter isolation regression test (internal/service/est_profile_counter_isolation_test.go) proves a future shared-counter refactor would fail at compile-time pointer-identity check. Pre-commit verification (sandbox): gofmt clean, go vet clean (excluding repository/postgres which the sandbox can't build — disk-space testcontainers download), staticcheck clean across cms/trustanchor/api/handler/api/router/scep/intune/ratelimit/ service/pkcs7/domain/cmd/server, go test -short -count=1 green for every non-postgres package. G-3 docs-drift guard reproduced locally clean (Phases 5-7 added zero new env vars; Phase 1 already documented per-profile SERVER_KEYGEN_ENABLED). Spec preserved at cowork/est-rfc7030-hardening-prompt.md. Phases 8-13 (GUI ESTAdminPage / CLI+MCP / libest e2e / bulk revocation / docs/est.md / release prep) remain — post-2.1.0 work. |

EST RFC 7030 hardening master bundle Phases 2-4: end-to-end mTLS sibling
route + RFC 9266 channel binding + HTTP Basic enrollment-password +
per-source-IP failed-auth limit + per-(CN, sourceIP) sliding-window cap.
Two new shared packages so EST + Intune share infrastructure:
- internal/cms/ — RFC 9266 tls-exporter extractor (ExtractTLSExporter
with stdlib-panic recovery for synthetic ConnectionStates) +
CSR-side channel-binding parser via raw TBSCertificationRequestInfo
walk (the stdlib's csr.Attributes can't represent the OCTET STRING
binding value), VerifyChannelBinding composite, EmbedChannel-
BindingAttribute fixture helper, typed sentinel errors for missing
/ mismatch / not-TLS-1.3 mapped to HTTP 400 / 409 / 426 in handler.
- internal/trustanchor/ — extracted from scep/intune/trust_anchor*.go
so the EST mTLS sibling route + Intune dispatcher share the same
SIGHUP-reloadable PEM bundle primitive. intune.TrustAnchorHolder
is now `= trustanchor.Holder` (type alias) + NewTrustAnchorHolder =
trustanchor.New (function alias) — every existing call site compiles
unchanged. Intune's LoadTrustAnchor is a thin wrapper over
trustanchor.LoadBundle. White-box tests moved to the new package.
- internal/ratelimit/ — extracted from scep/intune/rate_limit.go (this
was Phase 4.1, in the same bundle). intune.PerDeviceRateLimiter
is now a thin wrapper preserving the (subject, issuer)→key
composition; EST handler reaches for SlidingWindowLimiter directly.
ESTHandler grew six optional fields wired by per-profile setters
(SetMTLSTrust / SetChannelBindingRequired / SetEnrollmentPassword /
SetSourceIPRateLimiter / SetPerPrincipalRateLimiter / SetLabelForLog)
plus four new mTLS-route methods (CACertsMTLS / SimpleEnrollMTLS /
SimpleReEnrollMTLS / CSRAttrsMTLS); shared internal pipeline
handleEnrollOrReEnroll(reEnroll, viaMTLS) keeps the auth/binding/
rate-limit gates DRY. New router method RegisterESTMTLSHandlers
registers /.well-known/est-mtls/<PathID>/{cacerts,simpleenroll,
simplereenroll,csrattrs}; AuthExemptDispatchPrefixes extends the
no-auth chain to /.well-known/est-mtls.
cmd/server/main.go's EST loop wires per-profile mTLS holder +
channel-binding policy + per-principal limiter + (when EnrollmentPassword
non-empty) Basic + source-IP limiter; new preflightESTMTLSClientCATrust-
Bundle returns *trustanchor.Holder so SIGHUP rotates the EST mTLS
bundle live without restart. SCEP + EST mTLS profiles now share a
single union mtlsUnionPoolForTLS passed to buildServerTLSConfigWithMTLS
(replaces the protocol-specific scepMTLSUnionPoolForTLS); per-handler
re-verify enforces "cert must chain to THIS profile's bundle" so
cross-protocol bleed is blocked at the application layer even though
the TLS layer trusts certs from either pool's union.
Phase 3.3 source-IP failed-Basic limiter defaults: 10 attempts / 1h
/ 50k tracked IPs (no env var; tunable in a follow-up). Phase 4.2
per-principal limiter cap from CERTCTL_EST_PROFILE_<NAME>_RATE_
LIMIT_PER_PRINCIPAL_24H (existing field, Phase 1 shipped).
New tests:
- internal/cms/channelbinding_test.go: extractor + CSR-side parser +
composite + TLS-1.3 round-trip end-to-end + EmbedChannelBinding-
Attribute round-trip
- internal/trustanchor/holder_test.go: parseBundlePEM white-box +
LoadBundle + Holder Get/Pool/SetLabelForLog/Reload-happy/
Reload-keeps-old-on-failure/Reload-keeps-old-on-expired/
WatchSIGHUP-reloads-pool/WatchSIGHUP-stop-clean
- internal/api/handler/est_hardening_test.go: 16 named cases covering
mTLS no-trust-pool 500 + no-cert 401 + cross-profile cert 401 +
happy-path 200 + CACertsMTLS auth gate + CSRAttrsMTLS auth gate +
channel-binding required-absent-rejected + not-required-absent-
allowed + writeChannelBindingError mapping + Basic no-header 401
+ Basic wrong-password 401 + Basic correct-200 + Basic-no-password
no-gate + per-IP failed-attempt lockout 429 + per-principal
blocks-after-cap + different-principals-independent + no-limiter-
unbounded.
Pre-commit verification (sandbox): gofmt clean, go vet clean
(excluding repository/postgres which the sandbox can't build —
disk-space testcontainers download), staticcheck clean for
cms/trustanchor/api/handler/api/router/scep/intune/ratelimit/
cmd/server, go test -short -count=1 green for cms/trustanchor/
api/handler/api/router/scep/intune/ratelimit/service. G-3
docs-drift guard reproduced locally clean (Phase 1 already
documented every new env var; Phases 2-4 added zero new env vars).

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

fix(scep-intune): close 11 audit gaps from 2026-04-29 pre-tag review
Closes the eleven gaps identified in the pre-v2.1.0 audit of the SCEP
RFC 8894 + Intune master bundle (cowork/scep-bundle-gap-closure-prompt.md).
Constitutional rule from cowork/CLAUDE.md::Operating Rules — 'Always
take the complete path, not the easy path' — drove this closure: each
gap was a load-bearing wire that crossed multiple layers (config →
validator → service wire-up → tests → docs) and shipping the bundle
without them would have produced lying-field footguns where operator-
visible config options stored values without affecting behavior.
WHAT LANDS:
Phase A — Clock-skew tolerance (master prompt §15 hazard closure)
internal/scep/intune/challenge.go: ValidateChallenge migrated from
positional args to ValidateOptions{} struct; new ClockSkewTolerance
field with default 0 (strict). 24 call sites updated mechanically.
Asymmetric application: now+tolerance >= iat AND now-tolerance < exp.
internal/config/config.go: SCEPIntuneProfileConfig.ClockSkewTolerance
default 60s + Validate() refusal when >= ChallengeValidity.
cmd/server/main.go: SetIntuneIntegration signature extended;
per-profile env-var loader honors CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CLOCK_SKEW_TOLERANCE.
internal/service/scep.go: intuneClockSkew field + IntuneStatsSnapshot
surfaces clock_skew_tolerance_ns. web/src/api/types.ts mirrors.
4 new tests in challenge_test.go covering accept-within-tolerance,
reject-beyond-tolerance, accept-expired-within-tolerance,
negative-treated-as-zero defensive normalization.
docs/scep-intune.md updated with the new env var + time-bounds rule.
Phase B — unknown-version-rejected golden test
internal/scep/intune/golden_helper_test.go: goldenUnknownVersionPayload
helper + signGoldenChallengeAny generic signer.
challenge_golden_test.go: TestGoldenChallenge_UnknownVersionRejected
uses an in-process ECDSA fixture (the on-disk PEM was generated with
a Go-stdlib version that produces different ecdsa.GenerateKey bytes
from the current call). TestRegenerateGoldenFixtures emits the new
unknown_version fixture file too.
Phase C — Two named Intune e2e tests
internal/api/handler/scep_intune_e2e_test.go:
TestSCEPIntuneEnrollment_RateLimited_E2E (cap=2 + 3 attempts; 3rd
returns FAILURE+badRequest with rate_limited counter ticked)
TestSCEPIntuneEnrollment_TrustAnchorSIGHUPReload_E2E (rotate
on-disk PEM + holder.Reload(); old-key challenge fails with
badMessageCheck; signature_invalid counter ticked)
intuneE2EFixture struct extended with trustHolder + trustPath fields
so tests can rotate.
Phase D — Four new ChromeOS hermetic tests (10 total now)
internal/api/handler/scep_chromeos_test.go:
_RAKeyMismatch — PKIMessage encrypted to wrong RA cert; handler
rejects without reaching service.
_3DESBackwardCompat — RFC 8894 §3.5.2 legacy fallback verified.
_RSACSR + _ECDSACSR — explicit matrix-pair pinning.
buildTestECDSACSR helper for ECDSA P-256 CSR construction;
tripleDESCBCEncrypt mirrors aesCBCEncrypt for 3DES-CBC;
assertChromeOSPositiveCertRep shared assertion.
Phase E — Per-profile counter isolation test
internal/api/handler/scep_profile_counter_isolation_test.go:
TestSCEPHandler_PerProfileIntuneCountersIsolated wires two
SCEPService instances + drives distinct PKIMessages + asserts
counter isolation. Guards against a future cmd/server/main.go
refactor that shares a *intuneCounterTab across profiles.
buildPerProfileIntuneFixture parameterized helper.
Phase F — Server-boot regression tests
cmd/server/preflight_scep_intune_test.go: 3 named tests covering
disabled-backward-compat, broken-config-with-PathID, expired-cert
refusal. preflightSCEPIntuneTrustAnchor signature extended with
pathID arg so error messages carry PathID= for operator log-grep.
Phase G — docs/connectors.md
Four new subsections under §EST/SCEP Integration: multi-profile
dispatch + mTLS sibling route + Intune Connector dispatcher + SCEP
probe in network scanner. Each has a one-paragraph operator
explanation + an env-var or endpoint table.
Phase H — Coverage uplift
internal/service/scep_probe_persist_test.go: 5 unit tests on
persistProbeResult (nil-safe + nil-repo-safe + repo-error swallow +
nil-logger guard) + ListRecentSCEPProbes (empty-slice-not-nil + repo
pass-through) + describeCertAlgorithm (RSA/ECDSA/QF1008-nil-curve
defensive branch/Ed25519/DSA/empty). CI gates (service ≥70, handler
≥75) PASS at 70.9% / 79.3%.
Phase I — deploy/test integration variant
deploy/test/scep_intune_e2e_test.go (//go:build integration):
TestSCEPIntuneEnrollment_Integration + _RateLimited_Integration
against the live docker-compose certctl container. Skip-when-
stack-missing semantics so sandbox + CI both work.
deploy/docker-compose.test.yml: new e2eintune SCEP profile env
vars + bind-mount of deploy/test/fixtures/.
deploy/test/fixtures/README.md: documents the deterministic trust
anchor regeneration recipe.
VERIFICATION (sandbox):
gofmt -d — clean for all changed files
staticcheck — clean for intune + handler + config + service +
cmd/server packages
go vet — clean for the same packages
go test -short — green for intune (95.3% cov), service (70.9%),
handler (79.3%), config (94.0%), cmd/server (boot
path; my preflight tests cover the directly-
testable function), pkcs7 (80.5% informational)
DEFERRED (per closure prompt §7 out-of-scope):
- V3-Pro Conditional Access gating + Microsoft Graph integration
- Standalone certctl-scan CLI binary
- OCSP rate-limiting, OCSP stapling, delta CRLs
Spec preserved at cowork/scep-bundle-gap-closure-prompt.md;

fix(scep-probe): satisfy staticcheck QF1008 in describeCertAlgorithm
CI flagged QF1008 on the chained selector pub.Curve.Params() — the linter wants the promoted-method form pub.Params() (Curve is embedded in ecdsa.PublicKey, so Params is reachable via promotion). Restructure the nil check so the embedded interface still gets validated before the promoted call, then invoke pub.Params() once and reuse the result. Verification: * gofmt clean * staticcheck on internal/service/...: clean * 6/6 TestProbeSCEP_* tests still pass |

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.

refactor(scep-gui): rebrand SCEP admin surface to per-profile tabbed interface (Profiles + Intune + Recent Activity)
Phase 9 follow-up to the SCEP RFC 8894 + Intune master bundle. The
Phase 9.4 GUI shipped 'SCEP Intune Monitoring' at /scep/intune, which
made the per-profile observability surface look Intune-only — operators
running EJBCA + Jamf would never click that nav link expecting per-
profile RA cert + mTLS observability. The page is per-profile keyed
under the hood; this commit rebrands + restructures so the surface
matches what operators actually need.
Spec: cowork/scep-gui-restructure-prompt.md.
User-visible change:
- Nav link renamed: 'SCEP Intune' → 'SCEP Admin'.
- Route: /scep is the new canonical path; /scep/intune kept as a
backward-compat alias that lands directly on the Intune tab.
- Page header: 'SCEP Administration'.
- Three tabs:
* Profiles (default) — per-profile lean cards with RA cert
expiry countdown, mTLS sibling-route status badge, Intune
enabled/disabled badge, challenge-password-set indicator.
'View Intune details →' link on Intune-enabled cards
deep-links into the Intune tab.
* Intune Monitoring — the existing Phase 9.4 deep-dive
(per-status counters, trust anchor expiry, recent failures
table, reload-trust button + confirmation modal).
* Recent Activity — full SCEP audit log filter merging all
four action codes (scep_pkcsreq + scep_renewalreq +
scep_pkcsreq_intune + scep_renewalreq_intune); chip filters
for All / Initial / Renewal / Intune / Static.
Backend:
* internal/service/scep.go — new SCEPProfileStatsSnapshot type +
IntuneSection sub-block + ProfileStats(now) accessor. Adds
raCertSubject/raCertNotBefore/raCertNotAfter + mtlsEnabled +
mtlsTrustBundlePath fields with SetRACert + SetMTLSConfig setters.
Existing IntuneStatsSnapshot + IntuneStats(now) preserved
UNCHANGED for /admin/scep/intune/stats backward compat (the
JSON shape stays byte-stable for external consumers — the
aliasing approach the prompt initially suggested doesn't work
because the new shape nests Intune while the old one is flat).
ChallengePasswordSet is derived from challengePassword != ''
(the secret value itself is never surfaced).
* internal/api/handler/admin_scep_intune.go — new Profiles handler
method on AdminSCEPIntuneHandler with the same M-008 admin gate.
AdminSCEPIntuneServiceImpl extended (in place; same
map[string]*service.SCEPService) to satisfy the new
AdminSCEPProfileService interface. Single handler file gets the
third method so the M-008 pin entry count stays steady (no new
file, no new triplet of admin-gate test files — just three new
Profiles tests inside the existing test file).
* internal/api/router/router.go — one new route
'GET /api/v1/admin/scep/profiles' registered to
reg.AdminSCEPIntune.Profiles. HandlerRegistry unchanged.
* api/openapi.yaml — new operation 'listSCEPProfiles' documenting
the request body / response shape / error mapping. Existing
Intune entries unchanged.
* cmd/server/main.go — per-profile loop now calls
scepService.SetMTLSConfig(profile.MTLSEnabled,
profile.MTLSClientCATrustBundlePath) right after SetPathID, and
scepService.SetRACert(raCert) right after loadSCEPRAPair returns
the leaf cert. Both setters are nil-safe.
* internal/api/handler/m008_admin_gate_test.go — extended the
existing admin_scep_intune.go entry's justification to mention
the third endpoint. No new map entry needed (file already
listed).
Backend tests (8 new):
* TestAdminSCEPProfiles_NonAdmin_Returns403
* TestAdminSCEPProfiles_AdminExplicitFalse_Returns403
* TestAdminSCEPProfiles_AdminPermitted_ForwardsActor — also pins
that Intune-enabled profiles emit an 'intune' sub-block while
Intune-disabled profiles OMIT it.
* TestAdminSCEPProfiles_RejectsNonGetMethod
* TestAdminSCEPProfiles_PropagatesServiceError
* TestAdminSCEPProfilesServiceImpl_NilMapReturnsEmpty
* (existing 16 Phase 9 admin tests still pass — backward-compat
preserved)
Frontend:
* web/src/api/types.ts — new SCEPProfileStatsSnapshot +
IntuneSection + SCEPProfilesResponse types. Existing
IntuneStatsSnapshot et al unchanged.
* web/src/api/client.ts — new getAdminSCEPProfiles helper.
* web/src/pages/SCEPAdminPage.tsx — full rewrite as the tabbed
surface. Reuses the existing ConfirmReloadModal and Intune
deep-dive card components verbatim; adds ProfileSummaryCard
(lean card for the Profiles tab) and ActivityTab. URL state
sync via useSearchParams so deep links survive reloads + browser
back/forward. The legacy /scep/intune route alias defaults the
activeTab to 'intune' on mount.
* web/src/main.tsx — new <Route path='scep' /> + preserved
<Route path='scep/intune' /> alias. Both render SCEPAdminPage.
* web/src/components/Layout.tsx — nav link rebranded:
label 'SCEP Intune' → 'SCEP Admin', to '/scep/intune' → '/scep'.
Frontend tests (20 — full rebuild):
* Admin gate (non-admin sees gated banner + zero admin API calls)
* Profiles tab default + Intune tab tabswitch + ?tab=intune deep
link + legacy /scep/intune alias all land on Intune
* Profiles tab status badges (Intune + mTLS + challenge-set)
reflect each profile's flags
* RA cert expiry tone bands (good ≥30d / warn 7-30d / bad <7d /
EXPIRED) verified across three fixture profiles
* 'View Intune details →' only renders for Intune-enabled
profiles AND switches tabs on click
* Empty-state banner when no profiles configured
* Intune tab counters render with the existing Phase 9 deep-dive
shape; reload modal Open/Confirm/Cancel/Error paths all pinned
* Recent Activity tab merges all four SCEP audit actions across
four parallel useQuery calls; filter chips
(all/initial/renewal/intune/static) narrow correctly
* Error path surfaces ErrorState on the active tab
Docs:
* docs/scep-intune.md — Operational monitoring section heading
expanded to '(SCEP Administration → Intune Monitoring tab)'.
Page-surface description rewritten for the tabbed shape;
admin-endpoints list extended with the new /admin/scep/profiles
entry.
* docs/architecture.md — Microsoft Intune Connector trust anchor
subsection updated to reference the Intune Monitoring tab inside
the SCEP Administration page + lists all three admin endpoints.
* docs/legacy-est-scep.md — forward-ref expanded with a parallel
sentence for the per-profile observability surface (independent
of Intune).
* README.md — Enrollment Protocols bullet for Intune updated to
'admin GUI SCEP Administration page at /scep' with the three
tabs called out.
Verification:
* gofmt clean on touched files
* go vet ./... clean
* staticcheck on intune+service+handler+router+cmd-server clean
* go test -short across intune+service+handler+router+cmd-server:
all green (existing Phase 9 tests + new Profiles tests)
* Frontend tsc --noEmit clean
* Vitest: 20/20 SCEPAdminPage tests + 3/3 sibling AuditPage tests
pass
* G-3 docs-drift CI guard reproduced locally: clean (no new env
vars; existing CERTCTL_SCEP_ allowlist prefix covers everything)
* M-009 hard-zero useMutation guard reproduced locally: clean
(the existing reload mutation already used useTrackedMutation
from the Phase 9 follow-up commit

docs(scep-intune): deployment guide + troubleshooting + Microsoft support statement
Phase 11 of the SCEP RFC 8894 + Intune master bundle.
Phase 11.1 — docs/scep-intune.md (new, ~340 lines):
* TL;DR — drop-in NDES replacement framing; what an operator gets
over NDES (per-profile endpoints, audit-log forensics, SIGHUP
reload, GUI monitoring, per-device rate limit).
* Architecture diagram — Intune cloud → Connector → certctl SCEP
→ issuer connector. Explicit 'certctl replaces NDES, NOT the
Connector' framing; nine-gate dispatcher walk (shape pre-check,
JWS sig, version dispatch, time bounds, audience pin, CSR binding,
replay, per-device rate limit, optional compliance).
* Migration playbook (NDES + EJBCA / NDES + ADCS) — 9-step run-book:
install alongside, configure per-profile endpoint, extract trust
anchor, configure CONNECTOR_CERT_PATH + AUDIENCE, configure
issuer connector, migrate one profile, verify enrollment, roll
out fleet, decommission NDES.
* Intune SCEP profile field mapping table — every Intune admin
center field mapped to certctl's behavior (cert type, subject
name format, SAN, validity, key storage provider, key usage,
EKU, hash algorithm, SCEP server URL).
* Trust anchor extraction recipe — step-by-step certlm.msc export
of the 'CN=Microsoft Intune Certificate Connector' cert, PEM
rename, env-var configuration, HA Connector concatenation, SIGHUP
rotation flow.
* Troubleshooting matrix — 10 failure modes mapped to root causes
and operator actions: signature_invalid (trust anchor stale),
claim_mismatch (Intune profile SAN config), expired (clock skew /
Connector cert past NotAfter), not_yet_valid (reverse skew),
wrong_audience (URL mismatch), replay (retry-window collision),
rate_limited (limiter doing its job), unknown_version (Microsoft
shipped new format), malformed (proxy mangling body),
compliance_failed (V3-Pro hook returned non-compliant).
* Operational monitoring — admin GUI surface description, expiry
badge tone bands (≥30d green / 7-30d amber / <7d red / EXPIRED),
per-status counter polling cadence, audit log filter, recommended
Prometheus alert thresholds.
* Limitations — explicit V3-Pro deferrals: native Microsoft Graph
integration, Conditional Access compliance gating, per-tenant
trust anchors (MSP scoping), OCSP stapling at SCEP-response time,
auto-discovery of Connector signing cert.
* Microsoft support statement — three Microsoft Learn URLs (verified
live with HTTP 200): Connector overview, SCEP profile setup,
Connector install validation. Microsoft documents the Connector
as RFC-8894-compliant and supports its use against any RFC 8894
SCEP server.
Phase 11.2 — Cross-references:
* docs/legacy-est-scep.md — the previous forward-ref pointed at
'the Phase 11 doc this bundle ships'; updated to a richer pointer
that lists what scep-intune.md covers (architecture, migration,
profile mapping, extraction, troubleshooting, monitoring,
limitations, Microsoft support).
* README.md — new bullet under Enrollment Protocols table:
'Microsoft Intune SCEP fleet (drop-in NDES replacement)' with
the per-profile dispatcher feature list + link to scep-intune.md.
Procurement teams scanning the README see the Intune story
alongside ChromeOS / Jamf in the same table row.
* docs/architecture.md — new 'Microsoft Intune Connector trust
anchor (per-profile, opt-in)' subsection in the Security Model
section. ASCII diagram showing the dispatcher walk; calls out
the SIGHUP reload + admin-gated GUI surface; forward-link to
scep-intune.md.
Verification:
* All linked anchors inside scep-intune.md resolve to existing
headings: #limitations, #microsoft-support-statement,
#operational-monitoring, #trust-anchor-extraction.
* All linked doc paths resolve: legacy-est-scep.md, architecture.md,
features.md, tls.md.
* All three Microsoft Learn URLs return HTTP 200 (verified via curl).
* G-3 docs-drift CI guard reproduced locally and clean — the
migration playbook uses the <NAME> placeholder convention
consistently (matching features.md style) so the docs scanner
doesn't extract literal env-var names that aren't in config.go.
* Backend tests across intune+handler+service+router still green.

feat(scep-intune): golden-file tests + e2e harness against fixture trust anchor
Phase 10 of the SCEP RFC 8894 + Intune master bundle. Adds reproducible
testdata fixtures + a hermetic end-to-end test that exercises the full
handler → service → dispatcher → CertRep wire path.
Phase 10.1 — Golden-file tests (internal/scep/intune/):
* testdata/intune_trust_anchor.pem — deterministic ECDSA P-256 cert
seeded from a constant byte string (sha256-derived PRNG); regenerates
byte-identical PEM bytes across runs.
* testdata/intune_challenge_golden_success.txt — valid challenge,
iat/exp window covers goldenChallengeNow.
* testdata/intune_challenge_golden_expired.txt — same trust anchor +
payload shape but iat/exp shifted into the past.
* testdata/intune_challenge_golden_tampered_sig.txt — payload bytes
intact, last sig byte flipped.
challenge_golden_test.go reads each fixture and asserts:
- Success → ValidateChallenge returns a populated claim
(DeviceName / Subject / SANDNS pinned to the documented values).
- Expired → errors.Is(err, ErrChallengeExpired).
- Tampered → errors.Is(err, ErrChallengeSignature).
- Plus two defensive permutations: WrongAudienceReuse pins the
audience-check ordering after a successful sig verify;
RotatedTrustAnchorRejects pins the holder-rotation failure mode
using a freshly-generated unrelated trust cert.
golden_helper_test.go contains the deterministic-PRNG, ES256 signer,
fixture-load helpers, and the regeneration target. Operators flip
fixtures via:
go test -run='^TestRegenerateGoldenFixtures$' ./internal/scep/intune/... -args -update-golden
Why ECDSA + a deterministic seed: a hand-pasted base64 blob would
break on every Go stdlib bump (json.Marshal field ordering, ASN.1
encoding edge cases). Generating from a pinned seed gives
reproducible PEM bytes; only the ECDSA signature suffix varies
across regenerations (Go's stdlib doesn't expose RFC 6979
deterministic-k cleanly), and ValidateChallenge re-verifies the
signature on every read so it doesn't matter.
intune package coverage: 95.2% (was 94.8%).
Phase 10.2 — Hermetic end-to-end test (internal/api/handler/scep_intune_e2e_test.go):
Departs from the spec's deploy/test/ location because the handler
package already has the chromeOS-shape PKIMessage builders (buildTestCSR
/ buildEnvelopedDataForTest / buildSignedDataForTest / aesCBCEncrypt /
postPKIOperation). Putting the e2e test in the handler package lets it
reuse those helpers AND run in the default 'go test ./...' sweep —
every CI run exercises the full Intune dispatcher chain. The
deploy/test/ location is reserved for a future docker-compose-driven
variant that would mount a fixture trust anchor into the running
container; this hermetic version proves the wire works without that
dependency.
intuneE2EFixture stands up:
- A real Intune Connector signing keypair (ECDSA P-256) + cert
written to a temp PEM file the TrustAnchorHolder loads at startup.
- A real RA pair the SCEPHandler decrypts EnvelopedData with.
- A fixture issuer connector (intuneE2EIssuerConnector) that
records every IssueCertificate call + returns a deterministic
child cert chained to a fixture CA. Implements the full
IssuerConnector interface (IssueCertificate / RenewCertificate /
RevokeCertificate / GenerateCRL / SignOCSPResponse / GetRenewalInfo)
with the non-issuance methods stubbed.
- A capturing AuditRepository that records every Create call so
the test can assert action='scep_pkcsreq_intune' was emitted.
- A real SCEPService with SetIntuneIntegration wired to a real
ReplayCache + PerDeviceRateLimiter.
Three test scenarios:
1. TestSCEPIntuneEnrollment_E2E — the documented happy path. Forge
a valid Intune-shaped challenge (ES256 signed, length > 200, two
dots — satisfies looksIntuneShaped), build a CSR with CN matching
the claim's device_name, POST through HandleSCEP, decode the
CertRep, assert pkiStatus=SUCCESS + issuer.issued has one entry
+ audit log carries 'scep_pkcsreq_intune' + IntuneStats.counters[
'success']==1.
2. TestSCEPIntuneEnrollment_ClaimMismatchRejected_E2E — same setup
but CSR CN is 'attacker-host.example.com'. Dispatcher must
reject with CertRep FAILURE+BadRequest (mapIntuneErrorToFailInfo:
ErrClaimCNMismatch → BadRequest), no issuance, IntuneStats
counters['claim_mismatch']==1.
3. TestSCEPIntuneEnrollment_TamperedSignature_E2E — flip a byte in
the JWT signature segment of the Intune challenge before
wrapping it in the PKIMessage. Dispatcher rejects with
FAILURE+BadMessageCheck (signature errors → BadMessageCheck per
the same mapping table).
Important sanity learning during construction: the buildTestCSR
helper from scep_chromeos_test.go does NOT populate DNSNames on the
CSR. The success claim therefore omits san_dns to avoid tripping
ErrClaimSANDNSMismatch (claim says ['x'], CSR has nothing). The
claim_mismatch sibling test exercises the SAN-dimension via the
CN mismatch path; coverage of explicit SANDNS mismatches stays in
the unit tests in claim_test.go where the helper builds CSRs with
full SANs.
Verification:
* gofmt clean on touched files
* go vet ./internal/scep/intune/... ./internal/api/handler/...: clean
* staticcheck: clean
* go test -count=1 -cover ./internal/scep/intune/...: 95.2%
* 5 golden tests + 3 e2e tests all pass
* No new env vars (G-3 docs guard not triggered)
* No new HTTP routes (openapi-parity guard not triggered)
* Sibling test packages (service + router) still green

fix(scep-intune): use useTrackedMutation for trust-anchor reload (M-009)
Phase 9 follow-up — the M-009 hard-zero regression guard in
.github/workflows/ci.yml flagged the SCEPAdminPage's reload mutation as
a bare useMutation() call. The repo's invalidation contract requires
every mutation to go through useTrackedMutation with explicit
invalidates: QueryKey[] | 'noop' so cached data never goes stale after
a write.
Swap the bare useMutation for useTrackedMutation with
invalidates: [['admin', 'scep', 'intune', 'stats']] — the trust-anchor
reload changes the per-profile trust pool reflected in IntuneStats, so
the stats query MUST refetch on success. The audit-log queries stay on
their own 60s timer (a SIGHUP-equivalent reload doesn't backfill new
audit rows; nothing to invalidate there).
Verification:
* tsc --noEmit clean
* vitest SCEPAdminPage.test.tsx: 13/13 still pass (the wrapper's
onSuccess fires AFTER invalidation, so the modal-close + state
reset assertions hold)
* M-009 grep guard reproduced locally — bare useMutation sites = 0

feat(scep-intune): GUI monitoring tab + admin endpoints
Phase 9 of the SCEP RFC 8894 + Intune master bundle. Lands the operator-
facing Intune Monitoring tab plus the two admin-gated endpoints it reads
from. Per the constitutional 'complete path' rule: counters tick on
every typed dispatcher branch, the GUI poll is live (30s for stats,
60s for the audit log filter), and the SIGHUP-equivalent reload action
is one click + a confirmation modal — no follow-up plumbing required.
Backend (Phase 9.1 + 9.2 + 9.3):
* internal/service/scep.go gains:
- intuneCounterTab — atomic per-status counters keyed by the same
labels intuneFailReason() emits (success / signature_invalid /
expired / not_yet_valid / wrong_audience / replay / rate_limited /
claim_mismatch / compliance_failed / malformed / unknown_version).
Lock-free on the dispatcher hot path; snapshot() returns a
zero-allocation map for the admin endpoint.
- dispatchIntuneChallenge wires intuneCounters.inc(...) on every
typed return path INCLUDING the success leg (credited before
processEnrollment so a downstream issuer-connector failure
doesn't double-count).
- SetPathID + PathID accessors (so admin rows surface the SCEP
profile path ID per row).
- IntuneStatsSnapshot + IntuneTrustAnchorInfo public types, plus
IntuneStats(now) accessor that walks the trust holder pool and
packages a per-profile snapshot. ReloadIntuneTrust() is the
typed wrapper around TrustAnchorHolder.Reload that returns
ErrSCEPProfileIntuneDisabled when called on a profile where
Intune isn't enabled (admin endpoint maps that to HTTP 409).
* internal/api/handler/admin_scep_intune.go:
- AdminSCEPIntuneService narrow interface (Stats + ReloadTrust)
so the handler depends on a small surface; AdminSCEPIntuneServiceImpl
is the production walker over the per-profile SCEPService map.
- AdminSCEPIntuneHandler.Stats handles GET /api/v1/admin/scep/intune/stats
with the M-008 admin gate (non-admin → 403 + service never
invoked); returns {profiles, profile_count, generated_at}.
- AdminSCEPIntuneHandler.ReloadTrust handles POST
/api/v1/admin/scep/intune/reload-trust. Body is {path_id: '<id>'};
empty body targets the legacy /scep root profile. Returns 200 on
success / 404 on unknown PathID / 409 when the profile is Intune-
disabled / 500 on a parse error from intune.LoadTrustAnchor (the
holder retains its previous pool — fail-safe). 400 on malformed
JSON.
- ErrAdminSCEPProfileNotFound typed error so the handler can
distinguish 'wrong profile' from 'broken file'.
* internal/api/router/router.go: HandlerRegistry gains
AdminSCEPIntune; both routes registered as bearer-auth-required
(the admin-gate is at the handler layer per the M-008 pattern).
* cmd/server/main.go: declares scepServices map[string]*service.SCEPService
BEFORE HandlerRegistry construction so the same map can be referenced
from both the admin handler (constructed early) and the SCEP startup
loop (which populates it later by reference). The per-profile loop
now calls scepService.SetPathID(profile.PathID) and stores the service
pointer into the shared map. AdminSCEPIntune handler is constructed
at the same time as AdminCRLCache.
* internal/api/handler/m008_admin_gate_test.go: AdminGatedHandlers
map gains 'admin_scep_intune.go' with a one-line justification —
the regression scanner enforces the per-handler test triplet
(TestAdminSCEPIntune_NonAdmin_Returns403 + _AdminExplicitFalse_Returns403
+ _AdminPermitted_ForwardsActor) plus their POST siblings for
ReloadTrust.
* api/openapi.yaml: documents both endpoints with request body /
response shape / error mapping; openapi-parity-test now matches
the registered routes.
Frontend (Phase 9.4):
* web/src/pages/SCEPAdminPage.tsx — single-page Intune Monitoring
surface:
- Per-profile cards (one card per SCEP profile). Enabled profiles
get the full counter grid + trust-anchor-expiry badge tone
(good ≥30d / warn 7-30d / bad <7d / EXPIRED). Disabled profiles
get an off-state pill with the env-var hint to opt in.
- Counters polled every 30s via TanStack Query against
GET /admin/scep/intune/stats.
- Recent failures table (last 50) populated from the audit log
filtered to action=scep_pkcsreq_intune AND scep_renewalreq_intune;
merged + sorted by timestamp descending. Polled every 60s.
- Reload trust anchor button per profile + confirmation modal that
explains the SIGHUP equivalence and the fail-safe behavior.
onConfirm runs a TanStack mutation, refetches the stats query
on success, surfaces the underlying error (eg 'trust anchor
cert expired') in the modal on failure (modal stays open so
operator can retry).
- Admin gate: when authRequired && !admin the page renders an
'Admin access required' banner and the underlying admin API
requests are never issued (React Query enabled flag gated on
auth.admin) — server-side enforcement is M-008.
* web/src/api/types.ts: IntuneStatsSnapshot + IntuneTrustAnchorInfo +
IntuneStatsResponse + IntuneReloadTrustResponse.
* web/src/api/client.ts: getAdminSCEPIntuneStats +
reloadAdminSCEPIntuneTrust(pathID).
* web/src/main.tsx: new route /scep/intune. The route is unconditional;
the gating is at the page level so deep-links land cleanly.
* web/src/components/Layout.tsx: 'SCEP Intune' nav link between
Observability and Audit Trail with the appropriate sidebar icon.
Tests (Phase 9.5):
* internal/api/handler/admin_scep_intune_test.go (16 tests):
- M-008 admin-gate triplet for both Stats (GET) and ReloadTrust
(POST): NonAdmin / AdminExplicitFalse / AdminPermitted.
- Method-gate tests (Stats rejects POST, ReloadTrust rejects GET).
- Stats propagates service errors as 500.
- ReloadTrust maps ErrAdminSCEPProfileNotFound→404,
ErrSCEPProfileIntuneDisabled→409, generic err→500.
- Empty body targets legacy root PathID.
- Malformed JSON→400.
- AdminSCEPIntuneServiceImpl handles nil map + unknown PathID.
* web/src/pages/SCEPAdminPage.test.tsx (13 tests):
- Admin gate (non-admin sees gated banner + zero admin API calls;
admin sees the page; no-auth dev mode also passes).
- Profile rendering (counters with correct labels, expiry badge
tone for ≥30d / EXPIRED states, off-state pill for disabled
profiles, empty-state banner when no profiles configured).
- Reload modal (opens on click, calls mutation on Confirm,
keeps modal open + shows error on failure, Cancel skips
mutation).
- Error path renders ErrorState with retry.
- Audit log filter merges PKCSReq + RenewalReq events and sorts
descending.
Verification:
* gofmt clean on touched files
* go vet ./... clean
* staticcheck on intune/service/api/cmd-server clean
* go test -short across api+service+intune+cmd-server: all green
* web tsc --noEmit clean
* Vitest: SCEPAdminPage.test.tsx 13/13 + sibling page suites all
pass
* G-3 docs-drift CI guard: Phase 9 adds no new CERTCTL_* env vars
so the guard does not fire
* openapi-parity-test green (both new admin endpoints documented)
* M-008 regression scanner enforces the per-handler test triplet —
pin updated, all triplets present

feat(scep-intune): per-profile dispatcher + SIGHUP reload + per-device rate limit + compliance hook seam
Phase 8 of the SCEP RFC 8894 + Intune master bundle. Wires the internal/scep/intune validator from Phase 7 into the SCEPService dispatch path, with a SIGHUP-reloadable trust anchor holder, a per-(Subject, Issuer) sliding-window rate limiter, and a nil-default ComplianceCheck seam for V3-Pro. Operator-visible surface (per-profile, all default to off): CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_ENABLED=true CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CONNECTOR_CERT_PATH=/etc/certctl/intune.pem CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_AUDIENCE=https://certctl.example.com/scep/corp CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_CHALLENGE_VALIDITY=60m CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_PER_DEVICE_RATE_LIMIT_24H=3 Per-profile dispatch (Phase 8.8): an operator running corp-laptops through Intune AND IoT devices through static challenge configures INTUNE_ENABLED=true on the corp profile only — the IoT profile's PKCSReq path skips the dispatcher entirely. Mirrors the per-profile shape established by Phase 1.5. Wire-in surfaces: * config.go (Phase 8.1): SCEPProfileConfig.Intune sub-config of type SCEPIntuneProfileConfig (Enabled/ConnectorCertPath/Audience/ ChallengeValidity/PerDeviceRateLimit24h). Loaded from the indexed CERTCTL_SCEP_PROFILE_<NAME>_INTUNE_* env-var family. Per-profile Validate gate refuses INTUNE_ENABLED=true with empty ConnectorCertPath OR negative PerDeviceRateLimit24h. * cmd/server/main.go (Phase 8.2 + wire-in): preflightSCEPIntuneTrustAnchor helper mirrors preflightSCEPRACertKey/preflightSCEPMTLSTrustBundle shape — fail-loud at boot when the trust anchor file is missing / unreadable / empty / contains an expired cert. The per-profile loop builds the holder + replay cache + rate limiter, calls SetIntuneIntegration on the SCEPService, and starts the SIGHUP watcher. A deferred sweep stops every watcher at shutdown. * internal/scep/intune/trust_anchor_holder.go (Phase 8.5): TrustAnchorHolder mirrors cmd/server/tls.go::certHolder. RWMutex- guarded pool + Reload that swaps a fresh slice on success + WatchSIGHUP goroutine that responds to the same SIGHUP the existing TLS-cert watcher uses. A bad reload (parse error, expired cert) keeps the OLD pool in place so a half-rotation doesn't take Intune enrollment down — same fail-safe pattern. Operators rotate via the on-disk file then 'kill -HUP <certctl-pid>'. * internal/scep/intune/rate_limit.go (Phase 8.6): hand-rolled sliding-window-log limiter keyed by (Subject, Issuer). 100k-entry map cap (matches replay cache); at-cap drops the bucket whose newest timestamp is the oldest. Default 3 enrollments per 24h covers legitimate first-cert + recovery + post-wipe re-enrollment but blocks bulk enumeration from a compromised Connector signing key. maxN <= 0 disables the limiter for tests + the rare operator who wants no per-device cap. Empty subject short-circuits to allow (defense-in-depth: caller's claim validation rejects empty-subject upstream; no shared bucket on ''). Why hand-rolled instead of golang.org/x/time/rate: the rate package is in go.sum as an indirect transitive but not a direct dep. ~30 LoC of stdlib avoids creating a new direct dep. * internal/service/scep.go (Phase 8.3 + 8.4 + 8.7): - SCEPService gains intuneEnabled / intuneTrust / intuneAudience / intuneValidity / intuneReplayCache / intuneRateLimiter / complianceCheck fields. - SetIntuneIntegration() constructor-time injection wires the per-profile state. Profiles with INTUNE_ENABLED=false never call this method, so they pay zero overhead. - SetComplianceCheck() installs the V3-Pro plug-in (see Phase 8.7). - looksIntuneShaped(): JWT-shape pre-check (length > 200 + exactly two dots). Allowed to false-positive (validator catches malformed → ErrChallengeMalformed); MUST NOT false-negative on real Intune challenges. - dispatchIntuneChallenge(): the load-bearing core. Runs ValidateChallenge → CSR-binding via DeviceMatchesCSR → replay cache CheckAndInsert → per-device Allow → optional ComplianceCheck. Each failure leg increments a typed metric label and emits an audit-friendly Warn log line. - PKCSReq + PKCSReqWithEnvelope + RenewalReqWithEnvelope all call dispatchIntuneChallenge first; on outcome.decided=true they either short-circuit (with a typed-error → SCEPFailInfo mapping) or call processEnrollment with action='scep_pkcsreq_intune' (so audit greps can count Intune-vs-static enrollments). - mapIntuneErrorToFailInfo(): typed-error → SCEPFailInfo per RFC 8894 §3.2.1.4.5 (signature/replay/expired → BadMessageCheck; claim-mismatch → BadRequest; default → BadRequest). - intuneFailReason(): typed-error → metric label ('signature_invalid' / 'expired' / 'rate_limited' / etc.). Default 'malformed' so a previously-unseen error category still surfaces in the metric for follow-up. - ComplianceCheck (Phase 8.7): nil-default no-op gate. V3-Pro plugs in via SetComplianceCheck to call Microsoft Graph's compliance API. Returns (compliant, reason, err). nil-err + compliant=false → CertRep FAILURE + 'compliance' reason in audit. err != nil → fail-safe deny (V3-Pro module is responsible for any 'permit on API failure' policy). * internal/service/scep.go also gains parseCSRForIntune() — small private wrapper around encoding/pem + x509 used by the dispatcher for the claim ↔ CSR binding check (separated from the broader processEnrollment because we want to bind BEFORE consuming the replay-cache slot). Tests (gates: ≥85% coverage on intune package, ≥70% on service): * scep_intune_test.go (in internal/service): 14 dispatcher tests covering happy-path Intune enrollment + static-challenge fallback + tampered-challenge reject + claim-mismatch reject + replay detected + rate-limited + compliance-hook nil-default + compliance- hook denies non-compliant + compliance-hook error fails closed + IntuneEnabled accessor + 'no IntuneEnabled = static path unchanged' regression pin + intuneFailReason mapping for every typed error + looksIntuneShaped boundary cases. * trust_anchor_holder_test.go (in internal/scep/intune): NewLoadsBundle, NewRequiresLogger, NewSurfacesLoadError, ReloadHappyPath, ReloadKeepsOldOnFailure, ReloadKeepsOldOnExpired (the fail-safe semantics that make the SIGHUP path operator-friendly), WatchSIGHUPReloadsPool (real SIGHUP to self with poll-for-swap pattern mirroring cmd/server/tls_test.go), WatchSIGHUPStopIsClean (does NOT fire SIGHUP after stop — same caveat as the TLS test: the Go runtime would otherwise terminate the test runner on the next SIGHUP since signal.Stop has removed the handler). * rate_limit_test.go (in internal/scep/intune): AllowsUpToCap, DistinctKeysIndependent, WindowExpiry, DisabledBypass (maxN=0), NegativeCapDisabled, EmptySubjectShortCircuits (defense-in-depth against an empty-subject DoS chokepoint), DefaultCapsHonored, MapCapEvictsOldest (at-cap eviction branch), ConcurrentRaceFree (50 goroutines × 200 inserts), pruneOlderThan + the no-op case.

feat(scep-intune): parser + validator for Microsoft Intune Connector challenge format
Phase 7 of the SCEP RFC 8894 + Intune master bundle. Adds the
internal/scep/intune package that validates Microsoft Intune Certificate
Connector signed challenges embedded in SCEP CSR challengePassword
attributes. This is the parsing/validation foundation; Phase 8 wires it
into the SCEP service dispatcher.
What's included:
* doc.go — package architecture (Intune cloud → Connector → certctl
SCEP server) + 'what this package is NOT' guard rails. We do NOT
implement full JOSE: no JKU / kid / x5c trust, no JWKS fetch.
Trust anchor is operator-supplied at startup and pinned. The
package does NOT call Microsoft's API directly — the Connector
already did that; we validate its signed attestation.
* trust_anchor.go — LoadTrustAnchor(path) reads a PEM bundle of
Intune Connector signing certs. Skips non-CERTIFICATE PEM blocks
(operators sometimes paste chains with the priv key by mistake).
Rejects empty bundles + expired certs at startup with an
operator-actionable message including the cert subject. SIGHUP
reload lands in Phase 8.5; today it's load-once-at-boot.
* claim.go — ChallengeClaim struct + DeviceMatchesCSR helper.
Set-equality semantics for SAN-DNS/SAN-RFC822/SAN-UPN: the CSR
must carry EXACTLY the claim's elements, no extras and no missing.
Empty claim slice = no constraint on that dimension.
Per-dimension typed errors (ErrClaimCNMismatch /
ErrClaimSANDNSMismatch / ErrClaimSANRFC822Mismatch /
ErrClaimSANUPNMismatch) so audit logs surface the failure
dimension without string-matching. extractUPNSans is stubbed to
return nil with documented fail-closed behavior — non-empty UPN
claims fail the equalSets check (correct behavior; the rare deploy
that pins UPN SANs hot-fixes the ASN.1 walker per the inline
comment).
* replay.go — ReplayCache: bounded in-memory cache of seen nonces
with TTL. Sized for 100,000 entries (60-min Connector validity ×
25 RPS Intune fleet steady-state ≈ 90,000 challenges/hour with
headroom). sync.Map for concurrent read/write; janitor goroutine
wakes every TTL/4 to evict expired entries; at-cap O(N)
oldest-eviction (rarely fires; janitor keeps the cache below
cap). Redis-backed variant deferred to V3-Pro.
* challenge.go — the load-bearing piece:
- ParseChallenge(raw) splits the JWT-like compact serialization
into header/payload/signature and base64url-decodes each.
Tolerates both padded + unpadded encodings (some Connector
builds emit padded; RFC 7515 §2 says unpadded; we accept both).
Validates the header parses as JSON before returning so the
malformed-signal lands earlier in the pipeline.
- ValidateChallenge(raw, trust, expectedAudience, now):
1. ParseChallenge
2. JWS signature verify over (segment0 || '.' || segment1)
— re-derived from the raw on-wire bytes, NOT
re-base64-encoded, per RFC 7515 §3.1 (re-encoding could
produce a byte-different input than what was signed)
3. Signature alg dispatch:
RS256: rsa.VerifyPKCS1v15(SHA-256)
ES256: tries fixed-width r||s (JOSE-canonical) first,
falls back to ASN.1 DER (older Connectors)
alg=none: explicit reject with audit-log-friendly
message (RFC 7515 §3.6 attack vector)
HS*/PS*: rejected as 'unsupported alg' (no shared
secret in our threat model)
4. Version-detection prelude (versionedChallenge struct +
versionUnmarshalers map). Today's format is v1 (no
explicit version field; absence IS the v1 signal). Adding
v2 = adding a parser + a registration line; v1 path stays
untouched. Defends against the inevitable Microsoft format
change at ~30 LoC + 2 tests cost vs. a P0 incident.
5. Time bounds (iat / exp); audience pin (skipped when
expectedAudience == "").
Replay protection is the CALLER's job (handler glues parser +
cache; validator stays stateless + testable).
* Typed errors: ErrChallengeMalformed / ErrChallengeSignature /
ErrChallengeExpired / ErrChallengeNotYetValid /
ErrChallengeWrongAudience / ErrChallengeReplay /
ErrChallengeUnknownVersion. errors.Is-friendly so the handler
can audit failure dimension.
Tests (94.8% coverage):
* challenge_test.go (18 tests): happy-path RS256 + ES256
fixed-width + ES256 DER; TamperedSignature; TamperedPayload;
Expired; NotYetValid; WrongAudience; EmptyExpectedAudience
disables check; RotatedTrustAnchor; EmptyTrustBundle;
AlgNoneRejected; UnsupportedAlg (HS256); MissingAlg;
VersionV1ExplicitOK; VersionUnknownRejected;
MixedTrustBundle iter (skip key-type mismatches without
surfacing as Signature err); NonJSONPayloadButValidSignature;
Malformed cases (empty, missing dots, bad base64, non-JSON
header — 9 sub-cases); PaddedBase64Tolerated.
* claim_test.go (13 tests): per-dimension matching across CN +
SAN-DNS + SAN-RFC822 + SAN-UPN; nil guards; case-insensitive DNS
(RFC 4343); dedupe set-equality; empty claim = no constraint;
UPN stub canary; normaliseSet edge cases; equalSets length
mismatch.
* replay_test.go (11 tests): first-fresh; duplicate-rejected;
past-TTL-fresh; Sweep-evicts-expired; empty-nonce
short-circuits; at-cap LRU eviction; default-cap=100k;
Close-idempotent; TTL=0 disables janitor; concurrent-race-free
(50 goroutines × 200 inserts); empty-nonce twice is fresh both
times (we don't cache empties).
* trust_anchor_test.go: HappyPath single + multi cert; SkipsNonCertBlocks
(priv key + cert mix); EmptyBundleRejected; OnlyKeyBlocksRejected;
ExpiredCertRejected (with subject CN in error); MalformedCertRejected;
LoadTrustAnchor disk + EmptyPath + MissingFile.
* fuzz_test.go: FuzzParseChallenge with seed corpus covering both
the well-formed and the obvious-malformed shapes. Survived 187k
execs in 21s without panic on the local burst; CI runs 5 min.
Verification:
* gofmt -l ./internal/scep/intune: clean
* go vet ./internal/scep/intune/...: clean
* staticcheck ./internal/scep/intune/...: clean
* go test -count=1 -cover ./internal/scep/intune/...: 94.8%
(target was ≥85%)
* go vet ./internal/... ./cmd/...: clean (no rest-of-repo regressions)
* No new CERTCTL_* env vars (those land in Phase 8 with the
config gate); G-3 docs-drift CI guard not triggered.
* No new HTTP routes; openapi-parity guard not triggered.
Phase 8 will:
- Add SCEPProfileConfig.Intune* env vars + preflight gate
- Wire the validator into the SCEP service dispatcher
(Intune-shaped challenges → validator; static → existing path)
- Trust-anchor SIGHUP reload mirroring cmd/server/tls.go::watchSIGHUP
- Per-claim rate limit + audit metrics

feat(scep): mTLS sibling route /scep-mtls/<pathID> (opt-in)
SCEP RFC 8894 + Intune master bundle — Phase 6.5 of 14 (opt-in,
enterprise-procurement-checkbox).
Closes the procurement-team objection that 'shared password
authentication' is a checkbox-fail regardless of how strong the
password is. The clean answer: a sibling route that adds client-cert
auth at the handler layer AND keeps the challenge password (defense in
depth, not replacement). Devices present a bootstrap cert from a
trusted CA (e.g. a manufacturing-time cert), then SCEP-enroll for
their long-lived cert. Same model Apple's MDM and Cisco's BRSKI use.
internal/config/config.go
* SCEPProfileConfig gains MTLSEnabled bool + MTLSClientCATrustBundlePath
string. Indexed env-var loader reads
CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED +
CERTCTL_SCEP_PROFILE_<NAME>_MTLS_CLIENT_CA_TRUST_BUNDLE_PATH.
* Validate() refuses MTLSEnabled=true with empty bundle path —
structural defense in depth ahead of the file-content preflight.
cmd/server/main.go
* preflightSCEPMTLSTrustBundle: file existence + PEM parse + ≥1
CERTIFICATE block + non-expired check. Returns the parsed
*x509.CertPool ready to inject into the per-profile SCEPHandler.
Failures os.Exit(1) with the offending PathID in the structured log.
* SCEP startup loop walks each profile; when MTLSEnabled, runs
preflight, builds the per-profile pool, contributes the bundle's
certs to the union pool that backs the TLS-layer
VerifyClientCertIfGiven, clones the SCEPHandler with
SetMTLSTrustPool, and registers the parallel sibling route via
apiRouter.RegisterSCEPMTLSHandlers.
* Union pool published to outer scope as scepMTLSUnionPoolForTLS;
passed to buildServerTLSConfigWithMTLS so the listener serves both
/scep[/<pathID>] (no client cert) and /scep-mtls/<pathID>
(cert required at handler layer) on the same socket.
* Final-handler dispatch gains /scep-mtls + /scep-mtls/* prefix
routing through the no-auth chain (auth boundary is the client
cert + challenge password, NOT a Bearer token).
cmd/server/tls.go
* New buildServerTLSConfigWithMTLS that wraps buildServerTLSConfig
+ sets ClientCAs + ClientAuth=VerifyClientCertIfGiven when a
non-nil pool is passed. nil pool = identical TLS shape to the
pre-Phase-6.5 builder (no behavior change for deploys without
mTLS profiles).
* Critical: VerifyClientCertIfGiven (NOT RequireAndVerifyClientCert)
so a client that doesn't present a cert can still hit the standard
/scep route. The per-profile gate at the handler layer enforces
'cert required' on /scep-mtls/<pathID>.
internal/api/handler/scep.go
* SCEPHandler gains mtlsTrustPool *x509.CertPool field +
SetMTLSTrustPool method. Per-profile pool injected by
cmd/server/main.go after preflight.
* HandleSCEPMTLS wrapper: gates on r.TLS.PeerCertificates non-empty
+ per-profile cert.Verify against THIS profile's pool. Returns
HTTP 401 for missing/untrusted cert (mTLS failure is auth, not
authorization). Returns HTTP 500 if mtlsTrustPool is nil (deploy
bug — the route shouldn't have been registered). On success
delegates to HandleSCEP — defense in depth: mTLS is additive,
NOT replacement; the standard SCEP code path including the
challenge-password gate still executes.
* Per-profile re-verification via cert.Verify(...) is critical:
the TLS layer verified against the UNION pool, so a cert that
chains to profile A's bundle would pass TLS even when targeting
profile B. The handler-layer gate prevents cross-profile
bleed-through.
internal/api/router/router.go
* AuthExemptDispatchPrefixes gains '/scep-mtls' (auth boundary is
client cert + challenge password, NOT Bearer token).
* RegisterSCEPMTLSHandlers parallel to RegisterSCEPHandlers:
empty PathID maps to /scep-mtls root; non-empty maps to
/scep-mtls/<pathID>. Each handler in the map MUST have had
SetMTLSTrustPool called.
internal/api/router/openapi_parity_test.go
* SpecParityExceptions allowlists 'GET /scep-mtls' + 'POST
/scep-mtls' since the wire format is identical to /scep —
documenting both routes separately would duplicate every
operation row with no information gain. Documented alternative
in docs/legacy-est-scep.md.
internal/api/handler/scep_mtls_test.go (new, ~210 LoC)
* 6 tests + 2 helpers covering the auth contract:
1. RejectsMissingClientCert — request with r.TLS=nil → 401
2. RejectsUntrustedClientCert — cert chains to a different
CA → 401 (per-profile re-verification works)
3. AcceptsTrustedClientCert — cert chains to THIS profile's
pool → 200 (delegates to HandleSCEP)
4. StillRoutesThroughHandleSCEP — pin Content-Type + body
come from HandleSCEP delegate (defense in depth pin)
5. NoTrustPool_Returns500 — handler with SetMTLSTrustPool
never called → 500 (deploy-bug surface)
6. StandardRoute_StillNoMTLS — pin /scep keeps working
without a client cert even when mTLS pool is set
* genSelfSignedECDSACA + signECDSAClientCert helpers materialise
real cert chains (trusted-bootstrap-ca + trusted-device,
untrusted-attacker-ca + untrusted-device) so the Verify path
exercises real x509 chain validation, not mocks.
docs/features.md
* SCEP env-vars table extended with the two new MTLS env vars
(CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED,
CERTCTL_SCEP_PROFILE_<NAME>_MTLS_CLIENT_CA_TRUST_BUNDLE_PATH).
Closes the G-3 'env var defined in Go but never documented' gate.
docs/legacy-est-scep.md
* New 'mTLS sibling route (Phase 6.5, opt-in)' section covering
opt-in env vars, TLS server config (union pool +
VerifyClientCertIfGiven), handler-layer per-profile gate,
full auth chain on /scep-mtls/<pathID>, operator migration
workflow from challenge-password-only to challenge+mTLS.
cowork/CLAUDE.md::Active Focus
* 'HALF 1 COMPLETE' updated from '(Phases 0-5 of 14 SHIPPED)' to
'(Phases 0-6 + Phase 6.5 of 14 SHIPPED)'.
Verification:
* gofmt + go vet + staticcheck clean across api/handler /
api/router / config / cmd/server.
* go test -short -count=1 green across api/handler (with the new
scep_mtls_test.go) / api/router / service / config / pkcs7 /
cmd/server / connector/issuer/local.
* G-3 docs-drift CI guard local check: empty in both directions
after the new MTLS env vars landed in features.md.
* The constitutional test ('can an operator flip the bit and
observe the behavior change end-to-end?') is YES: setting
CERTCTL_SCEP_PROFILE_<NAME>_MTLS_ENABLED=true plus the trust
bundle path produces a working /scep-mtls/<pathID> endpoint
that accepts trusted client certs + rejects untrusted ones,
with no further code changes required.
Phase 6.5 of 14 in SCEP RFC 8894 + Intune master bundle.
Half 1 (Phases 0-6 + 6.5) is now FEATURE-COMPLETE for the
ChromeOS / general-MDM use case. Half 2 (Phases 7-12) adds the
Microsoft Intune dynamic-challenge layer.

docs(scep): close G-3 docs-only drift in legacy-est-scep.md
Two G-3 regression hits from the SCEP RFC 8894 docs that landed in
commit b33b843's docs/legacy-est-scep.md addition:
1. CERTCTL_SCEP_PROFILE_CORP_* (5 vars) — the multi-profile dispatch
recipe used literal CORP placeholders in the example block, which
the G-3 scanner treats as phantom env vars (the loader expands
<NAME> at runtime; CORP is never a literal env-var key in Go
source). Replaced the literal example with a prose description
that uses the <NAME> token explicitly + cross-references
docs/features.md where the per-profile suffix table lives. The
G-3 scanner sees only CERTCTL_SCEP_PROFILES + the prefix
CERTCTL_SCEP_ (already on the ALLOWED list per commit

docs(scep): RFC 8894 hardening — README + architecture + connectors
SCEP RFC 8894 + Intune master bundle — Phase 6 of 14.
Closes Half 1 of the bundle (Phases 0-6). The certctl SCEP server now
ships full RFC 8894 wire format (EnvelopedData decrypt + signerInfo POPO
verify + CertRep PKIMessage builder), tested against ChromeOS-shape
hermetic E2E requests, with multi-profile dispatch and must-staple
per-profile policy. Half 2 (Phases 7-12) adds the Microsoft Intune
dynamic-challenge layer; Phase 6.5 (mTLS sibling route) is independently
shippable as an opt-in enterprise-procurement feature.
README.md
* Standards & Revocation table SCEP row updated to mention full RFC
8894 wire format (EnvelopedData decryption, signerInfo POPO
verification, CertRep PKIMessage builder), PKCSReq + RenewalReq +
GetCertInitial messageType dispatch, multi-profile dispatch
(/scep/<pathID>), per-profile RA cert + key, MVP fall-through for
lightweight clients.
* Enrollment protocols paragraph extended with the same scope, plus
a link to docs/legacy-est-scep.md for the operator + device-
integration guide.
docs/architecture.md
* SCEP wire format paragraph rewritten to describe the two paths
(RFC 8894 first, MVP fall-through), the messageType dispatch
table, the EnvelopedData decrypt (constant-time PKCS#7 unpad
closing the padding-oracle leg), the SET-OF Attribute
re-serialisation quirk per RFC 5652 §5.4, and the CertRep
PKIMessage shape (cert chain encrypted to req.SignerCert, NOT
the RA cert).
* SCEP service interface updated to show the three new
*WithEnvelope variants alongside the legacy PKCSReq method.
* Added 'Capabilities advertised', 'Multi-profile dispatch', and
'Must-staple per profile' subsections covering the RFC 7633
extension policy.
docs/connectors.md
* EST/SCEP Integration section extended with the per-profile
issuer-binding env-var form (CERTCTL_SCEP_PROFILE_<NAME>_ISSUER_ID).

feat(scep): RenewalReq + GetCertInitial + ChromeOS E2E + caps + must-staple
SCEP RFC 8894 + Intune master bundle — Phase 4 + Phase 5 of 14.
Half 1 of the bundle's two halves is now COMPLETE through Phase 5:
the certctl SCEP server passes ChromeOS-shape hermetic E2E tests,
advertises the right capabilities, dispatches PKCSReq / RenewalReq /
GetCertInitial, and supports must-staple per-profile.
== Phase 4: RenewalReq + GetCertInitial wiring ============================
internal/service/scep.go
* RenewalReqWithEnvelope (RFC 8894 §3.3.1.2) — re-enrollment with an
existing valid cert. Same contract as PKCSReqWithEnvelope but the
service additionally verifies that envelope.SignerCert chains to
the issuer's CA (verifyRenewalSignerCertChain). A self-signed
throwaway cert (initial-enrollment shape) fails this check — that's
an indicator the client meant PKCSReq, not RenewalReq.
* GetCertInitialWithEnvelope (RFC 8894 §3.3.3) — polling stub.
Returns FAILURE+badCertID for all polls because deferred-issuance
isn't supported in v1 (every PKCSReq either succeeds or fails
synchronously). Wiring stays in place for a future enhancement.
* Audit actions: scep_pkcsreq vs scep_renewalreq — operators can
grep the audit log to distinguish initial enrollments from renewals.
internal/api/handler/scep.go
* SCEPService interface gains RenewalReqWithEnvelope +
GetCertInitialWithEnvelope.
* pkiOperation RFC 8894 path now switches on envelope.MessageType:
PKCSReq → PKCSReqWithEnvelope; RenewalReq → RenewalReqWithEnvelope;
GetCertInitial → GetCertInitialWithEnvelope; unknown → CertRep+FAILURE+
badRequest per RFC 8894 §3.3.2.2.
== Phase 5.1: GetCACaps capability advertisement =========================
internal/service/scep.go
* Caps string extended from 'POSTPKIOperation+SHA-256+AES+SCEPStandard'
to add 'SHA-512' (modern digest alternative now implemented in the
Phase 2 verifier) and 'Renewal' (the messageType-17 dispatch from
Phase 4). ChromeOS specifically looks for these capabilities to
negotiate the strongest available cipher + digest combo.
* scep_test.go pins the new caps so a future 'simplify caps' refactor
doesn't quietly remove ChromeOS-required negotiation flags.
== Phase 5.2: ChromeOS-shape integration tests ===========================
internal/api/handler/scep_chromeos_test.go (new, ~570 LoC)
* 6 hermetic E2E tests + ~12 helpers. Builds a real PKIMessage
in-test (acting as the ChromeOS client), POSTs through the handler,
parses the CertRep response back via the same internal/pkcs7/
builders the handler uses.
* TestSCEPHandler_ChromeOSPKIMessage_E2E — full RFC 8894 happy path:
SignedData(SignerInfo(deviceCert, sig over auth-attrs)) wrapping
EnvelopedData(KTRI(raCert), AES-CBC(CSR + challengePassword)) —
POSTed; verifies CertRep parses + RA signature verifies.
* TestSCEPHandler_ChromeOSPKIMessage_RenewalReq — pins messageType=17
routes to RenewalReqWithEnvelope, NOT PKCSReqWithEnvelope.
* TestSCEPHandler_ChromeOSPKIMessage_GetCertInitial — pins polling
returns CertRep with pkiStatus=FAILURE + failInfo=badCertID.
* TestSCEPHandler_ChromeOSPKIMessage_BadPOPO — corrupted signerInfo
signature falls through to MVP path (which also rejects since the
encrypted EnvelopedData isn't a raw CSR). No silent acceptance.
* TestSCEPHandler_ChromeOSPKIMessage_AESVariants — table-driven
AES-128/192/256-CBC; ChromeOS picks based on GetCACaps response.
* TestSCEPHandler_MVPCompat_StillWorks — pins the legacy MVP raw-CSR
path keeps working when no RA pair is configured. Backward compat
is non-negotiable.
== Phase 5.6: must-staple per-profile policy field (RFC 7633) ============
internal/domain/profile.go
* Added MustStaple bool to CertificateProfile. Default false; operators
opt in once they've confirmed the TLS reverse proxy / load balancer
staples OCSP responses (NGINX, HAProxy, Envoy support stapling but
require explicit config).
internal/connector/issuer/interface.go
* IssuanceRequest + RenewalRequest gained MustStaple bool (additive
field). Connectors that don't support extension injection (Vault,
EJBCA, ACME, etc.) silently ignore it — must-staple is a local-
issuer-only feature in V2 since upstream connectors enforce their
own extension policy.
internal/connector/issuer/local/local.go
* Added oidMustStaple (1.3.6.1.5.5.7.1.24, id-pe-tlsfeature) +
pre-encoded mustStapleExtensionValue (0x30 0x03 0x02 0x01 0x05 —
SEQUENCE OF INTEGER {5}, the TLS Feature for status_request per
RFC 7633 §6).
* generateCertificate signature gained mustStaple bool; when true,
appends pkix.Extension{Id: oidMustStaple, Critical: false, Value:
mustStapleExtensionValue} to template.ExtraExtensions before
x509.CreateCertificate.
internal/connector/issuer/local/must_staple_test.go (new)
* TestGenerateCertificate_MustStapleProfile_AddsExtension —
end-to-end: IssueCertificate with MustStaple=true → walks issued
cert's Extensions for the OID, verifies non-critical + DER bytes
match the constant.
* TestGenerateCertificate_NoMustStaple_OmitsExtension — pins the
'omit by default' contract (adding it by default would break
customer deployments where the TLS path doesn't staple).
* TestMustStapleConstants_PinExactRFC7633Bytes — locks the OID +
DER bytes against RFC 7633 §6 verbatim; round-trips through
asn1.Unmarshal as []int{5}.
Note: full service-layer plumbing (CertificateProfile.MustStaple →
IssuanceRequest.MustStaple → connector) flows through the issuer-side
field already; the per-call profile.MustStaple read at the service
layer (currently a no-op until SCEP/EST/CertificateService each plumb
through their respective IssueCertificate adapters) lands as a
follow-up. The load-bearing code path (the cert template) is correct
TODAY; flipping the service-layer flag is the missing wire.
== Phase 5.4: docs/legacy-est-scep.md ====================================
Added a new ~180-line section covering the SCEP RFC 8894 native
implementation: required env vars (CERTCTL_SCEP_RA_CERT_PATH +
_KEY_PATH), the openssl recipe for generating an RA pair, the
GetCACaps capability list, supported messageTypes, the MVP backward-
compat path, multi-profile dispatch (CERTCTL_SCEP_PROFILES + indexed
per-profile envs), ChromeOS Admin Console integration pointer, RA
cert rotation procedure, must-staple per-profile policy with the
'opt-in once your TLS path staples' caveat, operational notes
(audit actions, body-size cap, HTTPS-only), and a forward reference
to scep-intune.md (Phase 11).
== Verification ==========================================================
* gofmt + go vet clean for the files I touched.
* staticcheck ./internal/api/handler/... clean (the SA1019 lint on
extractChallengePasswordFromCSR uses the line-level //lint:ignore
directive matching the M-028 audit closure precedent).
* go test -short -count=1 green across api/handler / api/router /
service / pkcs7 / connector/issuer/local / domain / cmd/server.
* G-3 docs-drift CI guard local check: empty diff in both directions.
Phase 4 + Phase 5 of 14 in SCEP RFC 8894 + Intune master bundle.
Half 1 (Phases 0-5) is now feature-complete; Phase 6 (docs + smoke +
audit deliverables) lands next; then Phase 6.5 (mTLS sibling route,
opt-in) is independently shippable; then Half 2 (Phases 7-12) adds
the Microsoft Intune dynamic-challenge layer.

lint(scep): fix CI lint failures in Phase 3 commit (b540d44)
Three lint issues from golangci-lint that didn't fire locally because I
ran 'go vet' but not 'staticcheck' before commit (the recent crypto/signer
QF1008 incident pattern repeating — must run staticcheck before
committing per CLAUDE.md::pre-commit-verification-gate; landing this
fixup, then will run staticcheck on every future SCEP-bundle commit).
internal/pkcs7/envelopeddata.go:78
* ST1022: 'comment on exported var ErrEnvelopedDataDecrypt should be of
the form "ErrEnvelopedDataDecrypt ..."' — staticcheck enforces the
Go-doc convention that var/const docs start with the symbol name.
Renamed the leading 'Sentinel decryption error.' to
'ErrEnvelopedDataDecrypt is the sentinel decryption error.'
internal/pkcs7/certrep_test.go:246-247
* U1000: 'func nowMinus1Hour is unused' / 'func nowPlus30Days is unused'
— left-over helpers from a previous draft of selfSignedCertPEM that
inlined the time math. Removed both.
Verified with — clean. Tests still
green (handler 79.0% / service 73.2% / pkcs7 80.5%).
Restores green CI on the lint job for the Phase 3 push.

feat(scep): CertRep PKIMessage response builder (RFC 8894 §3.3.2)
SCEP RFC 8894 + Intune master bundle — Phase 3 of 14.
Implements the SCEP CertRep response builder + wires it into the handler's
RFC 8894 path. After this commit, certctl emits proper CertRep PKIMessage
responses (signed by the RA key, with EnvelopedData encrypting the issued
cert chain to the device's transient signing cert) for both success and
failure outcomes — RFC 8894 §3.3 mandates a PKIMessage response on every
PKIOperation request, including failure cases that carry pkiStatus=2 +
failInfo.
internal/pkcs7/certrep.go (new, ~370 LoC)
* BuildCertRepPKIMessage: assembles the full ContentInfo → SignedData →
{certs, signerInfo, encapContent} structure per RFC 8894 §3.3.2 +
RFC 5652 §5+§6.
* Success path: encrypts the issued cert chain (PKCS#7 certs-only)
INSIDE an EnvelopedData targeting req.SignerCert (the device's
transient cert, NOT the RA cert — response goes back to the device
encrypted with its public key). AES-256-CBC + random 16-byte IV +
PKCS#7 padding + RSA PKCS#1v1.5 keyTrans.
* Failure path: encapContent is empty (no EnvelopedData); the failInfo
auth-attr is populated.
* Pending path: encapContent is empty; client polls via GetCertInitial.
* Auth-attr ordering matches micromdm/scep for byte-level wire-format
diffing (DER SET-OF normalises order anyway, but matching the
reference implementation makes audit + manual inspection easier).
* senderNonce is freshly generated from crypto/rand on every call.
* RA key signs the canonical SET OF Attribute re-serialisation (RFC
5652 §5.4 quirk every CMS implementation hits — wire form is [0]
IMPLICIT but the signature is computed over EXPLICIT SET OF).
* Helper functions: buildCertRepAuthAttrs, buildSignerInfoCertRep,
signCertRep, buildEncapContentInfo, buildEnvelopedDataAES256, all
constructed via this package's existing ASN1Wrap primitives (avoids
asn1.Marshal nuances with nested RawValues — same pattern Phase 2
settled on).
internal/pkcs7/signedinfo.go (1-line tweak)
* ParseSignedData no longer refuses when SignerInfos is empty. The
degenerate certs-only SignedData form (RFC 8894 §3.5.1 GetCACert
response, RFC 7030 EST cacerts, AND now the encrypted certs-only
inner content of the CertRep EnvelopedData) is structurally valid
with zero signers. Caller decides whether the lack of signers is
an error in their context.
internal/pkcs7/certrep_test.go (new, ~230 LoC)
* TestBuildCertRepPKIMessage_Success_RoundTrip — full pipeline
round-trip: build → ParseSignedData → VerifySignature → auth-attr
extractors → ParseEnvelopedData(encapContent) → Decrypt with device
key → ParseSignedData(innerCertsOnly) → assert issued cert CN.
Catches drift between the build-side encoding and the parse-side
decoding.
* TestBuildCertRepPKIMessage_Failure_NoEncapContent — pkiStatus=2 +
failInfo populated; encapContent empty.
* TestBuildCertRepPKIMessage_FreshSenderNonceEachCall — pins the
'never reuse senderNonce' invariant from RFC 8894 §3.2.1.4.5
(replay defense).
* TestBuildCertRepPKIMessage_RejectsNonRSADeviceCert — pins the
RSA-only requirement on the device's transient cert (KTRI requires
RSA pubkey for keyTrans encryption).
* TestBuildCertRepPKIMessage_NilArgs_Refuses.
internal/pkcs7/certrep_fuzz_test.go (new, ~150 LoC)
* FuzzBuildCertRepPKIMessage — varies transactionID + senderNonce +
signerCert; asserts no panic. When build succeeds for the success
path, asserts round-trip soundness (output parses back via
ParseSignedData). 6s seed-corpus run hit no panics.
internal/api/handler/scep.go
* pkiOperation now emits writeCertRepPKIMessage for the RFC 8894
path (both success AND failure). MVP path keeps writeSCEPResponse
for backward compat with lightweight clients.
* tryParseRFC8894 extended to extract the RFC 2985 §5.4.1
challengePassword attribute from the recovered CSR, so the
service-layer's challenge-password gate can run on the RFC 8894
path the same way it does on the MVP path. Returns
(envelope, csrPEM, challengePassword, ok) — was 3-tuple before.
* extractChallengePasswordFromCSR helper mirrors the MVP path's
extractCSRFields logic; same staticcheck SA1019 carve-out for
the deprecated csr.Attributes API (RFC 2985 challengePassword
has no non-deprecated stdlib API per the M-028 audit closure).
* writeCertRepPKIMessage helper wraps pkcs7.BuildCertRepPKIMessage;
on build failure (programmer/config bug) returns HTTP 500 rather
than try a fallback PKIMessage that might re-trigger the same bug.
Verification:
* gofmt + go vet clean across pkcs7 / api/handler.
* go test -short -count=1 green across pkcs7 / api/handler /
api/router / service / cmd/server.
* Coverage: pkcs7 80.5% (was 78.4% before Phase 3). Handler/service
held steady.
* Fuzz seed-corpus (6s): FuzzBuildCertRepPKIMessage — no panic;
round-trip soundness invariant held for every successful build.

feat(scep): EnvelopedData decrypt + signerInfo POPO verify (RFC 8894 §3.2)
SCEP RFC 8894 + Intune master bundle — Phase 2 of 14.
Implements the new RFC 8894 PKIMessage parse path: EnvelopedData parser
+ decryptor, signerInfo parser + signature verifier, handler dispatch
that tries the RFC 8894 path FIRST and falls through to the legacy MVP
raw-CSR path on any parse failure. Backward compat with lightweight SCEP
clients is preserved by design — no behavior change for any existing
deploy that doesn't set CERTCTL_SCEP_RA_*.
internal/pkcs7/envelopeddata.go (new, ~330 LoC)
* ParseEnvelopedData: parses CMS EnvelopedData per RFC 5652 §6.1, with
optional outer ContentInfo unwrapping. Handles SET OF RecipientInfo
+ IssuerAndSerial form rid (RFC 8894 §3.2.2).
* EnvelopedData.Decrypt: RSA PKCS#1 v1.5 key-trans + AES-CBC (128/192/
256) or DES-EDE3-CBC content decryption with **constant-time PKCS#7
padding strip** (no branch on padding-byte values; closes the
padding-oracle leak surface). Recipient mismatch is BadMessageCheck
per RFC 8894 §3.3.2.2 (NOT BadCertID); every failure mode returns
the same ErrEnvelopedDataDecrypt sentinel to close timing-leak legs
of Bleichenbacher attacks.
* Equivalent to micromdm/scep's cryptoutil/cryptoutil.go::DecryptPKCS-
Envelope (cited in code comments; not vendored — fuzz-target
ownership stays in this sub-package per the operating rule).
internal/pkcs7/signedinfo.go (new, ~370 LoC)
* ParseSignedData / ParseSignerInfos: parses CMS SignedData per RFC
5652 §5.3. Resolves each SignerInfo's SID (IssuerAndSerial v1 OR
[0] SubjectKeyId v3) against the SignedData certificates SET to
pluck the device's transient signing cert.
* SignerInfo.VerifySignature: re-serialises signedAttrs as the
canonical SET OF Attribute (the RFC 5652 §5.4 quirk every CMS
implementation hits — wire form is [0] IMPLICIT but the signature
is over EXPLICIT SET OF). Hashes with SHA-1/SHA-256/SHA-512 +
verifies via RSA PKCS1v15 or ECDSA per the cert's pubkey type.
* Auth-attr extractors: GetMessageType (PrintableString-decimal),
GetTransactionID, GetSenderNonce, GetMessageDigest. SCEP attr OIDs
pinned (RFC 8894 §3.2.1.4).
internal/pkcs7/{envelopeddata,signedinfo}_fuzz_test.go (new)
* FuzzParseEnvelopedData / FuzzParseSignedData / FuzzParseSignerInfos
/ FuzzVerifySignerInfoSignature — every parser certctl adds gets a
panic-safety fuzzer (the fuzz-target-ownership rule from
cowork/CLAUDE.md::Operating Rules). Local 5s runs hit ~270k
executions per parser without panic. Errors are expected for
arbitrary inputs; only panics are bugs.
internal/pkcs7/{envelopeddata,signedinfo}_test.go (new)
* Round-trip tests that materialise real RSA/ECDSA pairs, hand-build
the wire bytes, parse + decrypt + verify, and assert plaintext /
auth-attr equality. The build helpers use this package's ASN1Wrap
primitives directly (asn1.Marshal of structs containing nested
asn1.RawValue is finicky for mixed Class/Tag); gives byte-level
control matching what real SCEP clients emit.
* Negative tests: tampered ciphertext / tampered auth-attrs / wrong
RA / wrong key / mismatched recipients / random garbage all return
the appropriate sentinel error without panic.
internal/service/scep.go
* PKCSReqWithEnvelope: RFC 8894 envelope-aware variant. Returns
*SCEPResponseEnvelope (not error + *SCEPEnrollResult) because RFC
8894 §3.3 mandates a CertRep PKIMessage on every response, even
failures — the handler shouldn't translate Go errors into SCEP
failInfo codes. Returns nil to signal 'invalid challenge password'
so the caller can translate to HTTP 403 (matches MVP path's wire
shape; RFC 8894 §3.3.1 is silent on this case).
* mapServiceErrorToFailInfo: exact mapping table from the prompt
(CSR parse → BadRequest, CSR sig → BadMessageCheck, crypto policy
→ BadAlg, default → BadRequest).
internal/api/handler/scep.go
* SCEPService interface gains PKCSReqWithEnvelope.
* SCEPHandler now optionally carries an RA cert + key pair. SetRAPair
upgrades the handler to the RFC 8894 path; without that call the
handler stays MVP-only (the v2.0.x behavior).
* pkiOperation: tries the RFC 8894 path FIRST when the RA pair is
set. tryParseRFC8894 helper does the full pipeline (ParseSignedData
→ VerifySignature → extract auth-attrs → ParseEnvelopedData → Decrypt
→ x509.ParseCertificateRequest the recovered bytes). On any failure
it falls through to the legacy extractCSRFromPKCS7 MVP path —
backward compat is non-negotiable.
* Phase 2 emits the legacy certs-only response on RFC 8894 success;
Phase 3 (next commit) swaps in writeCertRepPKIMessage with the
proper status / failInfo / nonce-echo wire shape.
cmd/server/main.go
* Per-profile loop now calls loadSCEPRAPair after preflight to load
the cert + key + inject via SetRAPair. crypto + crypto/tls imports
added.
* loadSCEPRAPair helper: tls.X509KeyPair-based parse + leaf cert
extraction. Failures here indicate TOCTOU between preflight + load.
internal/api/handler/scep_handler_test.go +
internal/api/router/router_scep_profiles_test.go
* mockSCEPService / scepProfileMockService gain PKCSReqWithEnvelope
stubs to satisfy the extended interface. Existing test cases
unchanged (they exercise the MVP path; RA pair is unset).
Verification:
* gofmt + go vet clean for the files I touched.
* go test -short -count=1 green across pkcs7 / api/handler /
api/router / service / cmd/server.
* Coverage: pkcs7 78.4% (was 100% — drops because new code includes
paths the round-trip tests don't yet hit, like decryption alg
fall-through and v3 SubjectKeyId SID matching).
* Fuzz-target seed-corpus runs (5s each, ~270k execs/parser): no
panic. Pre-merge fuzz-time bumps to 30s per the prompt's
verification gate.

feat(scep): per-issuer SCEP profiles — multi-endpoint dispatch
SCEP RFC 8894 + Intune master bundle — Phase 1.5 of 14.
Restructures SCEPConfig from a single flat struct (one IssuerID + one
RA pair + one challenge password) to a Profiles slice where each
profile binds its own URL path (/scep/<pathID>), issuer, optional
CertificateProfile, RA cert+key, and challenge password.
This phase is the FOUNDATION for Phases 2-12: every downstream handler
signature, service envelope, CertRep builder, GUI counter, and test
fixture takes a profile_id parameter from here on. Adding multi-profile
support post-bundle would cost 3x what greenfielding it now does.
Backward compat: legacy CERTCTL_SCEP_* flat env vars synthesise a
single-element Profiles[0] with PathID="" (legacy /scep root) when
CERTCTL_SCEP_PROFILES is unset. Existing operators see no behavior
change. New operators write multi-profile config directly via the
indexed env-var form.
Indexed env-var convention:
CERTCTL_SCEP_PROFILES=corp,iot,server
CERTCTL_SCEP_PROFILE_CORP_ISSUER_ID=iss-corp-laptop
CERTCTL_SCEP_PROFILE_CORP_PROFILE_ID=prof-corp-tls
CERTCTL_SCEP_PROFILE_CORP_CHALLENGE_PASSWORD=...
CERTCTL_SCEP_PROFILE_CORP_RA_CERT_PATH=/etc/certctl/scep/corp-ra.crt
CERTCTL_SCEP_PROFILE_CORP_RA_KEY_PATH=/etc/certctl/scep/corp-ra.key
... (etc per profile name)
internal/config/config.go
* SCEPConfig.Profiles []SCEPProfileConfig — primary multi-profile
dispatch source.
* Legacy flat fields (IssuerID, ProfileID, ChallengePassword,
RACertPath, RAKeyPath) preserved with updated docblocks marking
them as merge sources for the backward-compat shim.
* SCEPProfileConfig new struct (PathID, IssuerID, ProfileID,
ChallengePassword, RACertPath, RAKeyPath).
* loadSCEPProfilesFromEnv: reads CERTCTL_SCEP_PROFILES (comma-list
of names), expands each to per-profile env vars
CERTCTL_SCEP_PROFILE_<NAME>_*. Returns nil when unset so the
legacy-shim path takes over.
* mergeSCEPLegacyIntoProfiles: when SCEP enabled + Profiles empty +
any legacy flat field populated, synthesises Profiles[0] with
PathID="". No-op when Profiles already populated (structured form
wins) or SCEP disabled.
* validSCEPPathID: empty allowed (legacy /scep root); non-empty
must be [a-z0-9-] with no leading/trailing hyphen.
* Per-profile Validate gates: PathID format, uniqueness across the
slice, ChallengePassword presence (CWE-306 per profile), RA pair
presence (RFC 8894 §3.2.2), IssuerID presence.
* Legacy single-profile gates skip when Profiles is non-empty so
the per-profile loop owns the gating in the structured case
(avoids double-fire with overlapping error messages).
internal/api/router/router.go
* RegisterSCEPHandlers signature: map[string]handler.SCEPHandler
(was a single SCEPHandler).
* Empty PathID handler registered with literal r.Register('GET /scep'
+ 'POST /scep') so the openapi-parity AST scanner (Bundle D /
Audit M-027) continues to see the documented /scep route. Without
this preservation, the parity test fails because dynamic
string-built routes don't appear in *ast.BasicLit walks.
* Non-empty PathIDs registered dynamically as /scep/<pathID>.
* AuthExempt prefix /scep already covers all /scep[/...] paths via
prefix match — no change needed there.
cmd/server/main.go
* SCEP startup block iterates cfg.SCEP.Profiles, builds one service
+ one handler per profile, stuffs them into a {pathID -> handler}
map, hands the map to apiRouter.RegisterSCEPHandlers.
* Per-profile preflight: preflightSCEPChallengePassword,
preflightSCEPRACertKey, preflightEnrollmentIssuer fire ONCE PER
PROFILE with a profile-scoped slog.Logger so failures report
PathID + IssuerID. Each per-profile failure os.Exits(1) with a
targeted error message.
* Final 'SCEP server enabled' info log reports profile_count.
internal/config/config_scep_profiles_test.go (new, 9 tests / 22 sub-cases)
* TestSCEPConfig_LegacyFlatFields_SynthesizeSingleProfile — the
backward-compat smoke test.
* TestSCEPConfig_MultipleProfiles_LoadFromEnv — structured-form
happy path with two profiles.
* TestSCEPConfig_StructuredFormBeatsLegacy — when both forms set,
structured wins; legacy flat field MUST NOT leak into
Profiles[0].ChallengePassword.
* TestSCEPConfig_PathIDValidation — 13 sub-cases covering valid +
every reject mode (uppercase, slash, leading/trailing hyphen,
underscore, dot, space, non-ASCII).
* TestSCEPConfig_DuplicatePathID_Refuses.
* TestSCEPConfig_MissingPerProfileChallengePassword,
_MissingPerProfileRAPair (3 sub-cases),
_MissingPerProfileIssuerID — per-profile gate triplet.
* TestSCEPConfig_DisabledIgnoresProfiles — gates only fire when
SCEP is enabled.
internal/api/router/router_scep_profiles_test.go (new, 4 tests)
* TestRouter_RegisterSCEPHandlers_LegacyEmptyPathIDMapsToRoot —
empty PathID gets /scep root; both GET + POST routes registered.
* TestRouter_RegisterSCEPHandlers_NonEmptyPathIDMapsToSubpath —
non-empty PathID gets /scep/<pathID>; /scep root NOT registered
when no empty-PathID profile exists.
* TestRouter_RegisterSCEPHandlers_MultipleProfilesNoCrossBleed —
three profiles (default, corp, iot); each path reaches the right
handler instance, verified via per-profile-tagged GetCACaps mock
response.
* TestRouter_RegisterSCEPHandlers_EmptyMapRegistersNoRoutes — no
profiles → no /scep routes (deploy with SCEP disabled).
Verification:
* gofmt clean for the files I touched.
* go vet clean across config / router / cmd/server / domain.
* go test -short -count=1 green across config / router / cmd/server /
api/handler / service / domain / pkcs7.
* Coverage held: handler 79.0% / service 73.2% / pkcs7 100% /
config 96.0% / domain 88.6% / router 100% / cmd/server 19.2%.
* openapi-parity test green (literal /scep registrations preserved).
