Sprint 6 push (commits43836ac+663b14b) tripped three CI guards. Fixing all three in this single follow-up — each is a small, mechanical correction that doesn't change behavior: 1. staticcheck ST1021: AuditChainSnapshot doc comment was on the wrong type. internal/service/audit_chain_metric.go:91 had: // Snapshot returns the current counter state for the Prometheus // exposer. Reads use atomic loads — no mutex. type AuditChainSnapshot struct { ... } The comment described Snapshot() (the method on AuditChainCounter) but sat directly above the AuditChainSnapshot struct. staticcheck ST1021 requires exported-type comments to start with the type's name + optional leading article. Rewrote to lead with "AuditChainSnapshot is the point-in-time view ...". 2. multi-tenant-query-coverage: baseline drifted 31 → 32 because Sprint 6 COMP-002-RETENTION added UserRepository.ListDeactivatedBefore at internal/repository/postgres/user.go:191 — legitimately tenant-spanning by design. The retention policy is control-plane-wide (one CERTCTL_USER_RETENTION_WINDOW for the whole deployment, not per-tenant). The scheduler's userRetentionLoop walks every tenant's deactivated users on the same tick. A per-tenant tenant_id filter would require the scheduler to iterate every tenant — more code for equivalent semantics. Per the guard's own documentation (option b), legitimately tenant-spanning queries get an inline rationale comment + a baseline lift. Both delivered: - Inline comment block on the SELECT in user.go::ListDeactivatedBefore. - BASELINE_COUNT 31 → 32 in scripts/ci-guards/multi-tenant-query-coverage.sh, with the Sprint 6 rebase entry added to the rebase-history comment. 3. skip-inventory-drift: docs/testing/skip-inventory.md was stale. COMP-001-HASH added three new t.Skip sites in internal/repository/postgres/audit_chain_test.go (the three testing.Short() gates on the testcontainers integration tests). Re-ran ./scripts/skip-inventory.sh to regenerate the doc — totals went from 144 → 147 sites + 78 → 82 short-mode guards. Verified locally: bash scripts/ci-guards/multi-tenant-query-coverage.sh (clean) bash scripts/ci-guards/skip-inventory-drift.sh (clean) go vet ./... (clean) staticcheck ./internal/service/... (clean) Closes the three Sprint 6 CI failures. The next CI run should green out.
certctl Documentation

The full docs index, organized by audience. Pick the section that matches what you need to do; each link below opens a focused doc rather than a wall of text.

| Deployment model | Atomic write, post-deploy verify, rollback semantics across all targets |
| Vendor matrix | Tested vendor versions per target connector |
Connectors
The connector index is the canonical catalog (interfaces, registry, scanners, plus an inline reference per built-in). Per-connector deep-dive siblings cover operator-grade material — vendor edges, troubleshooting, rotation playbooks, when-to-use vs alternatives.
Issuers (13 deep-dives): ACME · ADCS · AWS ACM Private CA · DigiCert · EJBCA / Keyfactor · Entrust · GlobalSign Atlas HVCA · Google CAS · Local CA · OpenSSL / Custom CA · Sectigo SCM · step-ca / Smallstep · Vault PKI
Targets (15 deep-dives): Apache · AWS Certificate Manager · Azure Key Vault · Caddy · Envoy · F5 BIG-IP · HAProxy · IIS · Java Keystore · Kubernetes Secrets · NGINX · Postfix / Dovecot · SSH (agentless) · Traefik · Windows Certificate Store
