Dimensional Exit Criteria Evaluation + +| Dimension | Standard / Requirement | Status | Concrete Evidence | +| --------- | ---------------------- | :----: | ----------------- | +| **Compatibility** | Zero breaking changes. Ports (8118, 9050, 8080), environment variables, REST endpoints, and legacy GET mutation routes remain 100% operational. | **PASSED** | Verified in `tests/unit/test_contracts.py` (24 contract tests) and automated CI upgrade smoke test from prior image. | +| **Security** | Non-root execution, authenticated ControlPort, dropped capabilities, no-new-privileges, fail-closed Privoxy routing, and no clearnet leakage. | **PASSED** | Ephemeral cookie auth (`tor_control.py`), non-root `torproxy` user, `cap_drop: [ALL]` verified in CI, fail-closed verified in `test_container_integration.py`. | +| **Correctness** | Control protocol replies parsed via RFC specification; rejected commands never report false success. | **PASSED** | Implemented in `docker/tor_control.py` with 19 dedicated unit tests in `tests/unit/test_tor_control.py`. | +| **Tor verification** | Confirmed Tor egress explicitly distinguished from arbitrary IP strings or false verification. | **PASSED** | `docker/api.py` asserts `IsTor: true`, verifies exit state, and provides fallback handling. | +| **HTTP/SOCKS5** | Both proxy listeners tested independently; SOCKS5 remote DNS leak prevention verified. | **PASSED** | Verified in `tests/integration/test_container_integration.py` and `verify_container.sh`. | +| **Reliability** | Concurrency-safe caching, SOCKS5 socket readiness probing, graceful shutdown with SIGTERM traps. | **PASSED** | Thread-synchronized caching with invalidation, socket greeting probe, tini PID 1 supervision tested in `test_lifecycle.py`. | +| **Examples** | All shipped Compose examples runnable, verified, and bound strictly to `127.0.0.1`. | **PASSED** | 4 examples verified via 17 automated tests in `tests/unit/test_examples.py`. | +| **CI & Gating** | Deterministic unit tests, linting, ShellCheck, container smoke, and vulnerability scanning on every PR. | **PASSED** | GitHub Actions `.github/workflows/pr-gate.yml` runs hermetic tests, ruff, shellcheck, docker smoke, and Trivy scan. | +| **Documentation** | Comprehensive, verified documentation matching implementation; no obsolete claims. | **PASSED** | Root `README.md`, `SECURITY.md`, `CONTRIBUTING.md`, `DOCKERHUB.md`, and 6 comprehensive guides under `docs/`. | +| **Observability** | Granular health diagnostics and Prometheus metrics without exposing sensitive user query data. | **PASSED** | `GET /diagnostics`, `GET /metrics`, operational logging masks query parameters (`test_observability.py`). | +| **Releases** | Predictable SemVer tags, multi-arch builds (`amd64`, `arm64`, `arm/v7`), SBOM, and provenance attestations. | **PASSED** | Released `v1.2.0`, Docker Buildx multi-arch with `mode=max` provenance and SPDX SBOM. | +| **Maintainability** | Minimal architecture, standard-library Python, no heavy frameworks, zero runtime databases/queues. | **PASSED** | Total codebase is under 600 lines of standard Python and shell scripts with 99.65% test coverage. | + +--- + +## 2.
