- [x] Domain rules: models/repos/services forbidden from handlers/routes
- [x] Command rules: cmd/* restricted to stdlib + specific packages
- [x] Violations blocked: `golangci-lint run` fails

### Import Validation (Python)

- [x] No test skipping on CI (except marked slow for fast track)
- [x] Coverage always checked: no way to skip `--cov-fail-under`
- [x] Linters always run: no opt-out mechanism

### No Soft Errors
- [x] No `|| true` on quality gates
- [x] No `> /dev/null` hiding failures
- [x] No `--tb=no` or equivalent suppressing output
- [x] All failures visible in CI logs

### No Optional Linters
- [x] All Python linters required: ruff, ty, bandit, semgrep, pip-audit, interrogate
- [x] All Go linters required: golangci-lint (15+ linters)
- [x] All TS checks required: vitest coverage thresholds
- [x] No way to disable or override

### Per-File Exceptions (Documented)
- [x] Python per-file ignores documented in `pyproject.toml:993-1168`

## Audit Conclusion

**Status: ✅ PRODUCTION-READY**

All CI quality gates are properly configured, enforced, and documented. No bypass vectors detected. All gates use hard failure semantics with zero silent fallbacks. Configuration is opinionated, aggressive, and appropriate for production-grade code.

**Recommendation:** Maintain current enforcement levels. No changes required.
