Known Issues and Limitations

  • Some high-assurance runtime envelopes still require broader benchmark and regression evidence.
  • Certain external dependency failure combinations need additional hardening validation.
  • Policy explainability and operator-facing diagnostics continue to be refined.

Breaking Changes

  • Security public APIs in active major lines remain additive-first.
  • Any behavior change requiring migration must be versioned and documented in changelog/migration notes.

Program Execution Model — Wave Context

This module is scoped to Wave C — Security Production Validation in the program-level wave model. Wave C begins only after Wave B exit criteria are met. See ../../ROADMAP.md for the full Wave A → B → C → D gate model and exit criteria.

Wave C Scope for security

  • Security: complete Vault/HSM/PKI integration validation, provider failover, real RLS/query workloads, concurrent policy updates, and policy-conflict edge cases (tests/security/test_security_wavec_production_validation_focused.cpp) (Target: Q4 2026, done: 2026-08-17)

Wave C Entry Gate (prerequisite from Wave B)

  • Wave B gate is closed: retrieval chain baselines stable, ACM observability gates closed, hardware baselines confirmed (Target: Q4 2026)

Wave C Exit Criteria (this module's contribution)

  • Production-style security integration evidence complete (tests/security/test_security_wavec_production_validation_focused.cpp) (Target: Q4 2026, done: 2026-08-17)
  • Integrity and reliability verified under sustained load (tests/security/test_security_wavec_production_validation_focused.cpp) (Target: Q4 2026, done: 2026-08-17)
  • Policy gates consistently block boundary/license/hash/SBOM regressions (tests/security/test_security_wavec_production_validation_focused.cpp) (Target: Q4 2026, done: 2026-08-17)

Dependencies on Later Waves

  • Wave D operability hardening depends on stable Wave C security controls.
