+# Security Governance Policy
+
+## 1) Scope
+
+This policy applies to every pull request merged into `main`, including application code, infrastructure code, API/proto contracts, and CI/CD workflows.
+
+## 2) Required PR Security Gates
+
+Every PR MUST pass all of the following checks:
+
+1. **Dependency scanning**
+   - `npm audit --audit-level=high --omit=dev`
+   - `govulncheck ./...`
+2. **Secret scanning**
+   - `secretlint` and repository secret scanning workflow.
+3. **Static analysis scanning**
+   - `semgrep --config p/owasp-top-ten --error`
+4. **Filesystem vulnerability scanning**
+   - `trivy fs` (fail on `CRITICAL,HIGH`).
+
+Any failing critical gate blocks merge.
+
+## 3) Contract Tests for API/Proto Changes
+
+For any PR that changes API or proto surface (e.g. `api/**`, `*.proto`, generated protobufs), contract tests are mandatory and must pass before merge.
+
+## 4) Backward Compatibility Policy
+
+### Versioning
+
+- Public API/proto changes MUST follow semantic versioning principles:
+  - Backward-compatible additions: **minor** version bump.
+  - Breaking changes: **major** version bump.
+
+### Deprecation window
+
+- Deprecated fields/endpoints/RPCs must remain supported for at least **90 days** after deprecation notice.
+- Deprecation notices must include:
+  - exact deprecation date,
+  - planned removal date,
+  - migration path.
+
+### Breaking-change controls
+
+- Breaking changes require:
+  - explicit approval from maintainers,
+  - migration notes in release artifacts,
+  - validation that consumers have a migration path.
+
+## 5) Critical Findings SLA & Monitoring
+
+### SLA
+
+- **CRITICAL findings:** remediation or approved compensating control within **24 hours**.
+- **HIGH findings:** remediation within **7 calendar days**.
+
+### Monitoring & closure
+
+- Security findings from CI/security tools must be triaged on every PR.
+- Unresolved findings must be tracked with owner + due date.
+- PRs introducing unapproved CRITICAL findings must not merge.
+
+## 6) Exceptions
+
+Any policy exception must include written risk acceptance, compensating controls, and an expiry date approved by maintainers.
