oss-policy-kit 5.1.0

Open source starter kit for adopting OSS security baselines via policy packs, templates, evidence, and remediation.

OSS Security Policy as Code Starter Kit

Evaluate clone-visible OSS repository governance plus GitHub Actions, Azure Pipelines, and AWS CodeBuild/CodePipeline signals from a local clone. Platform truth outside the repository still requires evidence or manual review.

This project is intentionally small and explicit about trust boundaries. GitHub support is the most mature path today; Azure and AWS support are clone-based and evidence-driven rather than live platform verification.

Operational privacy: evaluation is local and clone-visible by default. API-backed evidence collection runs only when explicitly invoked, and should be scoped to the platform/repository being assessed.

At A Glance

Area	What you get
Current release	v5.0.0 / Python package oss-policy-kit==5.0.0
Input	A local repository clone
Output	evaluation-report.json and evaluation-report.md (optional SARIF 2.1.0 via --sarif-output)
Core scope	Clone-visible governance and GitHub/Azure/AWS CI/CD signals
Profiles	github-*, azure-*, aws-* ladders (level-1..3, release-hardening-*) — list with python -m oss_policy_kit profiles; optional bundled hybrids github-aws-level-2 / github-azure-level-2 are advisory-only; not for use as release gates
Exceptions	Waiver registry with owner, reason, and expiry
Examples	Hardened and vulnerable sample repositories
Assurance model	Each control is labelled deterministic, signal, or evidence-backed; the value flows into reports/1.0 JSON and Markdown so consumers can reason about proof strength. See docs/profiles/overview.md.

Recommended First Command

After installing, run the hardened example first:

python -m oss_policy_kit evaluate --target ./examples/hardened-repo --profile github-level-1 --output-dir ./out/hardened --summary-only

This confirms the CLI, bundled profile data, example repository, and report generation path before you evaluate your own repository.

Current Release State

v5.0.0 is the current public release line. It graduates the JSON report contract to the new default reports/1.0, introduces the Evidence Model v2 plus optional SARIF 2.1.0 output via --sarif-output, removes the legacy bundled profile alias github-release-hardening (use github-release-hardening-1), and tightens public-hygiene posture. The control catalog and profile control IDs are unchanged.

Surface	Current state
Package	oss-policy-kit==5.0.0
GitHub Release	v5.0.0 is the release target for wheel and sdist assets; v4.0.4 remains available as an immutable predecessor
Default branch	master
License	Apache-2.0 (LICENSE + NOTICE)
Report contract	reports/1.0 by default; 0.3 and 0.2 remain selectable via --report-json-contract. 0.1 was removed in v5.0.0
Security workflow	Scanners run in Security CI/CD; SARIF upload is gated by ENABLE_CODE_SCANNING_UPLOAD=true so validation does not fail when Code Scanning upload APIs are unavailable

The repository is designed to be reproducible from a clean clone: install the package, run the built-in examples, and compare the generated JSON/Markdown reports.

What's new in v5.0.0

Highlights only — full detail in CHANGELOG.md and the migration steps in docs/v5.0.0-migration-guide.md.

• Default JSON report contract is now reports/1.0. The new shape decouples wire stability from the package version. --report-json-contract 0.3 keeps the v4 shape byte-for-byte; 0.2 remains selectable; 0.1 was removed.
• Evidence Model v2. Each result in reports/1.0 carries a structured evidence object with source_type, collection_method, trust_level, attestation_status, freshness_status, evidence_required, and limitations. See docs/reports-contract-v1.0.md.
• SARIF 2.1.0 output. New --sarif-output PATH flag on evaluate. One SARIF result per fail or manual-review-required finding.
• Legacy profile alias removed. github-release-hardening (no numeric suffix) returns exit 2 with a migration error. Use github-release-hardening-1 (same control set).
• UTF-8 schema hygiene. The bundled evaluation-report-v3.schema.json is now UTF-8 without BOM (was UTF-16 in v4).
• Public-hygiene gate. scripts/check_public_hygiene.py is part of the release validation flow.

Breaking changes are limited to the items above. The --fail-on semantics, the bundled control catalog, profile control IDs, the Markdown report layout, and the surfaces of evaluate-many / recommend-profile / scaffold-evidence / collect-evidence / diff-reports are unchanged.

What This Kit Does

The starter kit helps you assess whether a repository shows a practical OSS baseline in files and workflows that are observable locally. It focuses on:

• SECURITY.md, CONTRIBUTING.md, LICENSE, CODEOWNERS, changelog presence
• clone-visible GitHub Actions, Azure Pipelines, and AWS build/pipeline structure and hygiene signals
• report generation for humans and pipelines
• policy lifecycle markers such as stable, experimental, and deprecated
• additive local evidence such as waivers and optional platform evidence files

It is not a universal application scanner, an OSPS certification engine, a compliance guarantee, or a substitute for threat modeling, secure code review, pentesting, or GitHub settings review. See docs/results-guide.md for the full applicability discussion.

Quickstart

Requires Python 3.12+.

Install (official channels)

1. From PyPI (recommended for most consumers):

   python -m pip install oss-policy-kit
   python -m oss_policy_kit --version
   

2. From GitHub Release artifacts — download oss_policy_kit-*.whl or oss_policy_kit-*.tar.gz from the Releases page, then pip install /path/to/wheel.

3. From source (contributors):

   python -m pip install -e ".[dev]"
   

Prefer python -m oss_policy_kit for CLI entry on Windows so you do not depend on Scripts\ being on PATH.

Run The Built-In Examples

python -m oss_policy_kit evaluate --target ./examples/vulnerable-repo --profile github-level-1 --output-dir ./out/vulnerable
python -m oss_policy_kit evaluate --target ./examples/hardened-repo --profile github-level-1 --output-dir ./out/hardened

What Success Usually Looks Like

• examples/hardened-repo on github-level-1: pass: 14 (all active controls in the profile)
• examples/vulnerable-repo on github-level-1: multiple fail
• github-release-hardening-1: typically pass plus one branch-protection result that remains manual-review-required or self-attested, depending on local evidence

For the full step-by-step demo (CLI help, profile discovery, fixture comparison, controls table, CI gating), see docs/validation-walkthrough.md.

CI/CD Integration

Starter workflows live under templates/workflows/:

• github-oss-policy-check.yml — baseline evaluate against github-level-1, fail the job when any control is fail.
• github-oss-policy-check-with-waivers.yml — same as above but passes --waivers ./waivers/waivers.yaml.
• github-oss-policy-check-level-2.yml — stricter github-level-2 profile.
• pipelines/azure/azure-pipelines.yml — Azure Pipelines example for lint, tests, package build, SBOM artifact generation, and self-check gating on a Linux/Ubuntu agent.

Typical CI command:

python -m oss_policy_kit evaluate --target . --profile github-level-1 --fail-on fail --output-dir ./oss-policy-reports

Exit codes in pipelines: 0 evaluation finished and the --fail-on threshold was not violated; 1 the gate tripped; 2 is usage or load errors. Keep the output directory as an artifact with if: always() so reviewers can inspect reports after a blocked run.

GitHub Releases for this kit include wheel and sdist distribution assets. The publish workflow also generates a CycloneDX SBOM as a CI artifact for release evidence.

Outputs

Each evaluate run writes:

• evaluation-report.md — human-readable report (summary, controls table, per-control detail)
• evaluation-report.json — machine-readable contract (default reports/1.0)
• evaluation-report.sarif — SARIF 2.1.0, only when --sarif-output is passed

For the JSON contract details see docs/reports-contract-v1.0.md and the legacy docs/reports-contract-v0.3.md. For result statuses (pass, fail, manual-review-required, self-attested, etc.) and how to interpret each one see docs/results-guide.md.

Maintainer Self-Check

Run the kit against this repository:

python -m oss_policy_kit evaluate --target . --profile github-level-1 --output-dir ./out/selfcheck

Treat the generated self-check report as authoritative for the current revision.

Optional maintainer scripts under scripts/:

• consumer_smoke.py — install the wheel into a clean venv and exercise the CLI end-to-end.
• twine_check_dist.py — run twine check against dist/*.whl / dist/*.tar.gz.
• check_public_hygiene.py — fail-fast guard against private tokens leaking into public files.
• demo-video.ps1 — PowerShell helper to record a CLI demo GIF/video; not part of CI or packaging.
