✅ Existing Quality Gates

On Every PR

• Build Verification (Node 20 + 22 matrix): ESLint, TypeScript compilation, dist output validation, api-proxy and cli-proxy unit tests
• Lint (separate job): ESLint + Markdownlint
• TypeScript Type Check: tsc --noEmit strict type checking
• Test Coverage: Jest unit tests with coverage comparison against base branch; PR comment with delta; fails on regression
• Integration Tests (5 parallel jobs): domain filtering, network security, protocol security, credential hiding, container/ops, API proxy — end-to-end Docker-based
• Chroot Integration Tests (4 parallel jobs): language runtimes (Python/Node/Go/Java/.NET), package managers (pip/npm/cargo/mvn/gem), /proc filesystem, edge cases
• Examples Test: 4 example shell scripts exercised against locally-built containers
• CodeQL: javascript-typescript + actions language analysis with security-extended,security-and-quality queries
• Dependency Vulnerability Audit: npm audit --audit-level=high for main + docs-site packages with SARIF upload to Security tab
• Security Guard (AI agent - Claude): reviews PR diff for security boundary weakening (iptables, Squid config, container hardening, domain patterns)
• PR Title Check: Enforces conventional commit format with type allowlist and lowercase subject pattern
• Link Check (MD changes only): Lychee link validator

Scheduled / Async Quality

• Performance Monitor (weekly): startup latency benchmarks with regression issue creation
• Daily Security Review + Dependency Security Monitor: ongoing vulnerability monitoring
• Secret Diggers (Claude/Copilot/Codex, hourly): AI-powered secret scanning
• Build-Test Workflow: Builds real projects (Go, Rust, Java, Node, etc.) through the AWF proxy
• Smoke Tests (every 12h + PR): End-to-end agentic runs of Claude, Copilot, Codex through the firewall

🔍 Identified Gaps

🔴 High Priority

1. Low Unit Test Coverage with Low Thresholds

The critical business logic files have very low unit test coverage:

• docker-manager.ts: 18% statements, 4% functions (250 statements, 25 functions mostly uncovered)
• cli.ts: 0% coverage (entry point entirely untested at unit level)
• Coverage thresholds are set very low: statements 38%, branches 30%, functions 35%

These are the most complex files orchestrating the entire container lifecycle, yet they're almost entirely untested at the unit level. Integration tests provide some coverage but don't count toward these metrics.

Risk: A regression in docker-manager.ts (e.g., wrong Docker Compose config generation, incorrect network topology) can pass all unit tests undetected.

2. No Container Security Scanning (Image Vulnerabilities)

There is no workflow that scans the built Docker images (squid, agent, api-proxy) for OS-level CVEs or package vulnerabilities (e.g., via Trivy, Grype, or Docker Scout). The dependency-audit.yml only covers npm packages.

Risk: Base images (ubuntu/squid:latest, ubuntu:22.04, Node.js) may contain critical OS CVEs that are not detected before being pushed to GHCR.

3. Performance Benchmarks Not Run on PRs

The performance-monitor.yml is weekly-only and never runs on pull requests. Container startup latency regressions introduced by a PR won't be caught until the weekly run.

Risk: A change to Docker Compose generation, healthcheck configuration, or network setup could silently degrade startup performance by 2-3x before being detected.

4. Integration Test Suite Missing CI Workflow Coverage

Per docs/INTEGRATION-TESTS.md, the following integration test categories have no CI workflow running them on PRs:

• Domain/Network tests (6 files, ~50 tests) — only test-chroot.yml runs these in some cases
• Protocol/Security tests (8 files, ~100 tests) — test-integration-suite.yml covers some
• Container/Ops tests (7 files, ~45 tests)

Mapping from the docs shows some tests may fall through gaps between the --testPathPatterns filters in test-integration-suite.yml.

---

🟡 Medium Priority

5. No Required Status Checks Policy Documented

The workflows exist but there's no documented or enforced branch protection configuration requiring specific checks to pass before merge. If branch protection is not configured with required checks, a failing build.yml could still allow a merge.

6. Coverage Thresholds Are Below Meaningful Levels

Current thresholds (38%/30%/35%/38%) are set to match the current baseline rather than aspirational targets. The test-coverage-improver agentic workflow runs weekly to improve this, but there is no roadmap or enforced timeline for reaching a minimum acceptable coverage (typically 60-80% for production code).

7. No Mutation Testing

The test suite doesn't include mutation testing (e.g., Stryker Mutator for TypeScript). This means tests may achieve coverage percentages while not actually asserting on important logic variations.

8. Smoke Tests Are Not Required for PR Merge (Reaction-Triggered)

smoke-claude.md, smoke-copilot.md, and smoke-codex.md run on PR events, but are also reaction-gated (reaction: heart/eyes/hooray). If reactions are the primary trigger, these expensive end-to-end tests may not always run on every PR, leaving a gap for regressions in agent-specific behavior.

9. No Docker Compose Schema Validation

src/docker-manager.ts generates Docker Compose YAML dynamically. There's no step that validates the generated docker-compose.yml against the Docker Compose schema (via docker compose config or JSON Schema). A malformed config would only be caught at runtime.

10. No Formatting Check (Prettier)

build.yml and lint.yml run ESLint but there's no Prettier formatting check. Code style inconsistencies accumulate over time and create noisy diffs.

---

🟢 Low Priority

11. No SBOM Generation

No Software Bill of Materials (SBOM) is generated or attached to releases. For a security-critical tool like AWF, an SBOM would aid supply chain transparency.

12. Workflow Action Pinning Inconsistency

performance-monitor.yml uses actions/checkout@v4 (floating tag), while all other workflows use pinned SHAs. This creates a minor supply chain risk for that specific workflow.

13. No Changelog Validation on PRs

While pr-title.yml enforces conventional commit format, there's no check that CHANGELOG.md or release notes are updated for feature/fix PRs.

14. Link Check Only Triggered on MD Changes

link-check.yml only runs when **/*.md files change. A refactoring that renames source files could silently break documentation links without triggering a link check.

15. No License Header / REUSE Compliance Check

There's no automated check that new source files include proper license headers, which can be important for an open-source project.

📋 Actionable Recommendations

HIGH: Unit Test Coverage for Core Logic

Issue: docker-manager.ts and cli.ts have near-zero unit test coverage.
Solution: Add unit tests using Jest mocks for execa (already a dependency) to test generateDockerCompose(), startContainers(), stopContainers(), and signal handling without needing Docker. The test-coverage-improver agentic workflow can be pointed specifically at these files.
Complexity: Medium (mocking execa and filesystem operations requires careful setup)
Impact: High — would catch config generation regressions, wrong network addresses, missing env vars

HIGH: Container Image CVE Scanning

Issue: No vulnerability scanning of built Docker images.
Solution: Add a container-security-scan.yml workflow that runs trivy image or docker scout cves on containers/squid/, containers/agent/, containers/api-proxy/ images and uploads SARIF to the Security tab. Can run on PR + weekly schedule.

- name: Scan agent image
  uses: aquasecurity/trivy-action@<sha>
  with:
    image-ref: 'ghcr.io/github/gh-aw-firewall/agent:latest'
    format: 'sarif'
    output: 'trivy-agent.sarif'

Complexity: Low
Impact: High — catches OS-level CVEs before GHCR publish

HIGH: Add PRs to Performance Monitor Trigger

Issue: Performance regressions only caught weekly.
Solution: Add pull_request trigger to performance-monitor.yml with a reduced iteration count (e.g., 2 vs 5), posting benchmark delta as a PR comment. Use continue-on-error: true to avoid blocking merges on transient performance variability.
Complexity: Low
Impact: High — immediate feedback on latency regressions

MEDIUM: Raise Coverage Thresholds Incrementally

Issue: 38%/30% thresholds are too low to catch real regressions.
Solution: Increase thresholds by 5% per quarter via the test-coverage-improver workflow. Set a roadmap target of 60% statements / 50% branches as a 6-month goal, enforced in jest.config.js.
Complexity: Low (config change + test writing)
Impact: Medium — raises confidence that new tests actually cover production paths

MEDIUM: Docker Compose Config Validation

Issue: Generated docker-compose.yml is never validated before container start.
Solution: Add a test in the unit test suite that calls generateDockerCompose() and pipes the output through docker compose config --quiet to validate schema. This can run in the existing test-coverage.yml job.
Complexity: Low
Impact: Medium — catches malformed YAML and invalid service configurations early

MEDIUM: Pin Actions in performance-monitor.yml

Issue: Floating tag actions/checkout@v4 creates supply chain risk.
Solution: Pin to SHA: actions/checkout@de0fac2e4500dabe0009e67214ff5f5447ce83dd (same as all other workflows).
Complexity: Very Low
Impact: Low-Medium — consistency in security posture

LOW: Add SBOM to Release Workflow

Issue: No SBOM attached to releases.
Solution: Add anchore/sbom-action to release.yml to generate and attach an SBOM artifact to each GitHub Release.
Complexity: Low
Impact: Low (supply chain transparency)

LOW: Broader Link Check Trigger

Issue: Link check skips non-MD PRs that may rename referenced files.
Solution: Change link-check.yml to also trigger on push to main (post-merge check) so broken links are always caught.
Complexity: Very Low
Impact: Low

🔮 The ancient spirits stir, and the smoke-test agent has walked this threshold.
The runes of build and browser answered true.
Yet two sigils remain veiled by absent tools.
So speaks the oracle: the watch continues.
