Closes M-006 + M-007 + M-008 + M-015 + M-016 + M-019 + M-020 from
comprehensive-audit-2026-04-25. M-028 was already closed by the
Bundle B CI follow-up.
M-006 (CWE-913) — Idempotent migration 000014
migrations/000014_policy_violation_severity_check.up.sql:
Prepended ALTER TABLE ... DROP CONSTRAINT IF EXISTS before the
ADD. Mirrors the down migration's existing IF EXISTS shape and
the M-7 idempotent-index idiom. Re-runs against partially-applied
DBs now succeed.
M-007 — Bulk-op partial-failure tests (3 new)
internal/api/handler/bulk_partial_failure_test.go:
TestBulkRevoke_PartialFailure_ReportsBoth
TestBulkRenew_PartialFailure_ReportsBoth
TestBulkReassign_PartialFailure_ReportsBoth
Each asserts HTTP 200 + both success/failure counters round-trip
+ per-cert errors[] preserved with non-empty messages so operators
can correlate each failure to its certificate ID.
M-008 — Admin-gated handler enumeration pin (verified-already-clean)
Recon: only one admin-gated handler — bulk_revocation.go — with
full 3-branch test triplet already in place. health.go calls
IsAdmin informationally to surface the flag to the GUI without
gating.
internal/api/handler/m008_admin_gate_test.go:
Walks every handler .go file, asserts every middleware.IsAdmin
call site is in AdminGatedHandlers (with required test triplet)
or InformationalIsAdminCallers (justified). Adding a new admin
gate without updating both the constant AND adding the test
triplet fails CI.
M-015 — Single-profile cardinality pin (verified-already-clean)
Audit claim 'no cardinality validation' was wrong — enforced at
struct level. domain.ManagedCertificate.{CertificateProfileID,
RenewalPolicyID,IssuerID,OwnerID} and RenewalPolicy.
CertificateProfileID are bare strings, not slices.
internal/domain/m015_cardinality_test.go:
reflect-based pin on kind=String. Schema change to N:N would
have to update renewal.go's lookup loop in the same commit.
M-016 (CWE-754) — Reap stale-agent jobs
internal/repository/postgres/job.go::ListJobsWithOfflineAgents:
JOIN jobs to agents on agent_id, filter (status=Running AND
a.last_heartbeat_at < cutoff), exclude server-keygen jobs.
internal/service/job.go::ReapJobsWithOfflineAgents:
Flips matched jobs to Failed reason agent_offline so I-001
retry loop re-queues them on a healthy agent. Records audit
event per reap.
internal/scheduler/scheduler.go:
Scheduler.runJobTimeout cycle now calls both reaper arms.
agentOfflineJobTTL default 5min (5x agent-health-check default);
SetAgentOfflineJobTTL knob for operator override.
internal/service/job_offline_agent_reaper_test.go: 6 unit tests
cover happy path, server-keygen-skip, non-Running-skip, non-
positive-TTL fail-loud, repo-error propagation, audit-event
recording.
M-019 — Configurable ARI HTTP timeout
Audit claim 'no fallback timeout' was wrong — ari.go:52 already
had a 15s timeout. Bundle C makes it configurable.
internal/connector/issuer/acme/acme.go:
Config.ARIHTTPTimeoutSeconds field with env path
CERTCTL_ACME_ARI_HTTP_TIMEOUT_SECONDS.
internal/connector/issuer/acme/ari.go:
Both HTTP clients (GetRenewalInfo + getARIEndpoint) now use the
new ariHTTPTimeout() helper. Zero / negative / nil-config all
fall back to the historic 15s default.
ari_timeout_test.go: 4 dispatch arm tests.
M-020 (CWE-770) — OCSP DoS hardening
Pre-bundle the noAuthHandler chain had no rate limit. An attacker
could DoS the OCSP responder, which for fail-open relying parties
is a revocation bypass.
cmd/server/main.go:
noAuthHandler refactored from fixed middleware.Chain(...) to a
conditional slice that appends middleware.NewRateLimiter when
cfg.RateLimit.Enabled. Per-IP keying applies; OCSP/CRL/EST/SCEP
are unauth.
docs/security.md (NEW):
Operator runbook documenting Must-Staple TLS Feature extension
RFC 7633 as the architectural fix for fail-open relying parties.
Profile-flip guidance + nginx/Apache/HAProxy/Envoy stapling
snippets + explicit scope statement on what the rate limiter
alone does NOT solve.
Audit deliverables:

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