Phase 8: Production readiness — failover tests, security hardening, sandboxing, deployment docs
- WP-1-3: Central/site failover + dual-node recovery tests (17 tests) - WP-4: Performance testing framework for target scale (7 tests) - WP-5: Security hardening (LDAPS, JWT key length, no secrets in logs) (11 tests) - WP-6: Script sandboxing adversarial tests (28 tests, all forbidden APIs) - WP-7: Recovery drill test scaffolds (5 tests) - WP-8: Observability validation (structured logs, correlation IDs, metrics) (6 tests) - WP-9: Message contract compatibility (forward/backward compat) (18 tests) - WP-10: Deployment packaging (installation guide, production checklist, topology) - WP-11: Operational runbooks (failover, troubleshooting, maintenance) 92 new tests, all passing. Zero warnings.
