Recent Backend and Framework Milestones

Release Area What changed
1.043.x Security audit governance Expanded security test corpus, finalized audit control narratives, and synchronized release/transparency metadata.
1.042.000 Security controls Introduced CSP nonce/strict-dynamic enforcement, capability tokens, runtime integrity monitor, credential-bridge removal, and Guardian hardening.
1.041.000 Audit control closure Completed correlation governance, telemetry join controls, privileged-role mutation hardening, and lifecycle zeroization closure.
1.037.000 Product model and UI framework Migrated Teams to Organizations, normalized dialog infrastructure, and introduced role-based design token architecture.
1.032.000 Observability and layout Added platform metrics infrastructure, public metrics transparency route, and reusable authenticated/public layout system.

Backend Governance Principles

  • Typed boundaries first: static analysis at PHPStan Level 9 is enforced in local and release workflows.
  • Sensitive mutations require explicit controls: capability tokens, role checks, and bounded rate-limit windows.
  • Security changes must ship with tests and transparency updates in the same release cycle.
  • Operational limits and telemetry boundaries are treated as enforceable policy, not advisory documentation.

Where to Inspect Implementation Evidence

  • docs/v1.changelog.md for detailed per-release technical notes.
  • docs/security/GEMINI_SECURITY_AUDIT_HANDOFF_AUDITOR_2026-03-23.md for control evidence narrative.
  • /transparency/security-audit/ for public audit posture snapshot.
  • /transparency/verification-governance/ for runtime gates and release governance controls.
