fix(bundle-5): Operational Liveness + Bootstrap — 4 audit findings closed
Closes Audit-2026-04-25 H-006 (High), H-007 (High), M-011 (Medium),
L-006 (Low — verified-already-closed via C-1 master closure in v2.0.54).
Hardens the orchestrator-facing surface — k8s probes, agent enrollment,
shutdown audit drain, scheduler config plumbing.
What changed
- internal/api/handler/health.go — split contract:
* /health stays shallow 200 (k8s liveness — process alive)
* /ready accepts *sql.DB; runs db.PingContext(2s); 503 on failure
* Nil DB path returns 200 + db=not_configured (test fixtures)
- internal/api/handler/agent_bootstrap.go (NEW) — verifyBootstrapToken:
* empty expected = warn-mode pass-through
* non-empty = `Authorization: Bearer <token>` required
* crypto/subtle.ConstantTimeCompare; length-mismatch path runs dummy
compare to keep timing uniform
* ErrBootstrapTokenInvalid sentinel
- internal/api/handler/agents.go — RegisterAgent calls verifyBootstrapToken
BEFORE body parse so unauth probes don't even allocate a JSON decoder
- internal/config/config.go — two new env vars:
* CERTCTL_AGENT_BOOTSTRAP_TOKEN (Auth.AgentBootstrapToken)
* CERTCTL_AUDIT_FLUSH_TIMEOUT_SECONDS (Server.AuditFlushTimeoutSeconds)
- cmd/server/main.go — 3 changes:
* pass *sql.DB into NewHealthHandler (H-006)
* pass cfg.Auth.AgentBootstrapToken into NewAgentHandler (H-007)
* configurable shutdown audit-flush timeout (M-011)
* one-shot startup WARN when bootstrap token unset (deprecation)
- new tests: agent_bootstrap_test.go (full deny/accept/warn-mode coverage,
constant-time compare path, length-mismatch); health_test.go extended
with /ready DB-probe failure (503), nil-DB pass-through, /health-shallow
L-006 verified
- cmd/server/main.go:557 already calls
sched.SetShortLivedExpiryCheckInterval(cfg.Scheduler.ShortLivedExpiryCheckInterval)
per the C-1 master closure in v2.0.54. Bundle 5 confirms; no code change.
Threat model: TB-1 (operator/orchestrator), TB-2 (Agent↔Server).
- CWE-754 (Improper Check for Unusual or Exceptional Conditions) for H-006
- CWE-306 + CWE-288 (Missing Authentication for Critical Function) for H-007
Verification
- go vet ./... → clean
- go build ./... → clean
- go test -short -count=1 ./... → all packages pass
- targeted Bundle-5 regressions → all pass
- npx tsc --noEmit (web) → clean
- npx vitest run (web) → in-flight (sandbox 45s
ceiling exceeded; no failure markers in dot stream; no frontend
changes in this bundle so no regression risk)
- python3 yaml.safe_load(api/openapi.yaml) → 89 paths
Backward compatibility
- Bootstrap token defaults to empty (warn-mode) — existing demo
deployments unaffected. Server logs deprecation WARN; v2.2.0 will
require it.
- Audit flush timeout default 30s preserves prior behaviour.
- Helm chart already routes readiness probe to /ready (no chart change
needed); now /ready actually probes the DB.
Bundle 5 of the 2026-04-25 comprehensive audit.
