## Summary
- adds a v5 permission coverage manifest with classifications, required permissions, denial reasons, and review justifications across REST, WebSocket, CLI, MCP, workflow, transition hook, command palette, and background job surfaces
- adds a Node-based coverage checker that fails when tracked surfaces are missing from the manifest or when REST route prefixes drift from the shared permission map
- wires the checker into CI and documents the manifest gate in the security guide
Closes#420.
## Verification
- `node scripts/check-permission-coverage.mjs`
- `./node_modules/.bin/prettier --check package.json .github/workflows/ci.yml scripts/check-permission-coverage.mjs docs/security/permission-coverage.json docs/security.md`
- `git diff --check`
- `pnpm lint:budget`
- `pnpm build`
- `pnpm audit --prod --audit-level=high` (passes high gate; 3 existing moderate findings)
- GitHub Actions: Build, Lint & Type Check, Security Audit, Workspace Unit Tests
