MANDATORY Requirements

CRITICAL: The following are NOT optional. Every project MUST have ALL of these. Do not skip any.

README Badges (MANDATORY)

Every project README.md MUST display these badges at the top, in this order:

<!-- Row 1: CI/Quality -->
[![CI](https://github.com/ORG/REPO/actions/workflows/ci.yml/badge.svg)](https://github.com/ORG/REPO/actions/workflows/ci.yml)
[![codecov](https://codecov.io/gh/ORG/REPO/graph/badge.svg)](https://codecov.io/gh/ORG/REPO)

<!-- Row 2: Security (MANDATORY) -->
[![OpenSSF Scorecard](https://api.securityscorecards.dev/projects/github.com/ORG/REPO/badge)](https://securityscorecards.dev/viewer/?uri=github.com/ORG/REPO)
[![OpenSSF Best Practices](https://www.bestpractices.dev/projects/PROJECT_ID/badge)](https://www.bestpractices.dev/projects/PROJECT_ID)

Badge	URL Pattern	MANDATORY
CI Status	github.com/ORG/REPO/actions/workflows/ci.yml/badge.svg	YES
Codecov	codecov.io/gh/ORG/REPO/graph/badge.svg	YES
OpenSSF Scorecard	api.securityscorecards.dev/projects/github.com/ORG/REPO/badge	YES
OpenSSF Best Practices	www.bestpractices.dev/projects/PROJECT_ID/badge	YES

CI/CD Workflows (MANDATORY)

Every GitHub project MUST have these workflows in .github/workflows/:

Workflow	File	Purpose	MANDATORY
CI	ci.yml	Build, test, lint	YES
CodeQL	codeql.yml	Security scanning	YES
Scorecard	scorecard.yml	OpenSSF Scorecard	YES
Dependency Review	dependency-review.yml	PR CVE check	YES

CI Must Include (MANDATORY)

Requirement	Implementation	MANDATORY
Coverage upload	codecov/codecov-action after tests	YES
Security audit	composer audit / npm audit / govulncheck	YES
SHA-pinned actions	All actions use full SHA with version comment	YES

Supply Chain Security (MANDATORY for Releases)

Supply chain security controls MUST block releases when violated.

Control	Implementation	Blocks Release?
SLSA Provenance	slsa-github-generator workflow	YES - no release without attestation
Signed Tags	git tag -s before gh release create	YES - unsigned tags rejected
SBOM Generation	anchore/sbom-action or cyclonedx	YES - SBOM required for compliance
Dependency Audit	composer audit / npm audit fails CI	YES - CVEs block merge

Release Workflow Order (MANDATORY)

Supply chain artifacts MUST be generated in this order:

1. CI passes (tests, lint, security audit)
     ↓
2. Create SIGNED tag locally: git tag -s vX.Y.Z
     ↓
3. Push signed tag: git push origin vX.Y.Z
     ↓
4. Create release on existing tag: gh release create vX.Y.Z
     ↓
5. SLSA provenance workflow triggers (workflow_run)
     ↓
6. Provenance attestation uploaded to release
     ↓
7. SBOM generated and uploaded

NEVER use gh release create without a pre-existing signed tag - this creates unsigned tags.

CI Integration for Supply Chain

Add to .github/workflows/release.yml:

# Pre-release checks (block release if failed)
- name: Security Audit
  run: |
    composer audit --format=plain || exit 1
    npm audit --audit-level=high || exit 1

# SBOM generation
- name: Generate SBOM
  uses: anchore/sbom-action@v0
  with:
    artifact-name: sbom.spdx.json
    output-file: sbom.spdx.json

- name: Upload SBOM to release
  run: gh release upload ${{ github.ref_name }} sbom.spdx.json
  env:
    GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Verification of Supply Chain Artifacts

Before announcing a release, verify:

• Release tag is GPG/SSH signed: git tag -v vX.Y.Z
• SLSA provenance exists: multiple.intoto.jsonl in release assets
• SBOM exists: sbom.spdx.json or sbom.cyclonedx.json in release assets
• No HIGH/CRITICAL CVEs: composer audit / npm audit clean

See references/slsa-provenance.md for detailed SLSA implementation guide.

OpenSSF Registration (MANDATORY)

1. Register at bestpractices.dev: https://www.bestpractices.dev/en/projects/new
2. Note the Project ID assigned after registration
3. Add badge to README with correct PROJECT_ID
4. Run Scorecard workflow to generate initial score

Codecov Setup (MANDATORY)

1. Enable Codecov for the repository at codecov.io
2. Collect coverage from ALL test suites (not just unit tests):

Test Suite	Coverage Command	Output File	MANDATORY
Unit	phpunit -c UnitTests.xml --coverage-clover	.Build/coverage/unit.xml	YES
Integration	phpunit -c IntegrationTests.xml --coverage-clover	.Build/coverage/integration.xml	YES
E2E	phpunit -c E2ETests.xml --coverage-clover	.Build/coverage/e2e.xml	YES
Functional	phpunit -c FunctionalTests.xml --coverage-clover	.Build/coverage/functional.xml	YES
JavaScript	npm run test:coverage	coverage/lcov.info	YES (if JS exists)

3. Upload ALL coverage files to Codecov:

   - uses: codecov/codecov-action@SHA # vX.Y.Z
     with:
       token: ${{ secrets.CODECOV_TOKEN }}  # MANDATORY - see below
       files: .Build/coverage/unit.xml,.Build/coverage/integration.xml,.Build/coverage/e2e.xml,coverage/lcov.info
       fail_ci_if_error: false
   

CODECOV_TOKEN (MANDATORY)

Never rely on tokenless uploads. They fail for protected branches and are unreliable.

Requirement	Implementation	Why
Token in secrets	Add CODECOV_TOKEN to repo or org secrets	Authentication
Token in workflow	token: ${{ secrets.CODECOV_TOKEN }}	Required for protected branches
Org-level secret	Preferred for consistency across repos	Single point of management

Failure without token:

Upload failed: {"message":"Token required because branch is protected"}

Get token from: https://app.codecov.io/gh/ORG/REPO/settings

Add as org secret (recommended):

# Organization-level (covers all repos)
gh secret set CODECOV_TOKEN --org netresearch --visibility all

# Or repository-level
gh secret set CODECOV_TOKEN --repo OWNER/REPO

JavaScript Coverage (MANDATORY for projects with JS/TS)

When a project contains JavaScript or TypeScript files:

1. vitest.config.js MUST include lcov reporter for Codecov:

   coverage: {
       provider: 'v8',
       reporter: ['text', 'json', 'html', 'lcov'],  // lcov REQUIRED for Codecov
       reportsDirectory: 'coverage',
   }
   

2. CI workflow MUST include JavaScript test job:

   - uses: actions/setup-node@SHA # vX.Y.Z
     with:
       node-version: '22'
   - run: npm install
   - run: npm run test:coverage
   

3. Codecov upload MUST include coverage/lcov.info

Verification Checklist

Before marking enterprise-readiness complete, verify ALL:

• README has CI badge linking to workflow
• README has Codecov badge (not "unknown")
• README has OpenSSF Scorecard badge (correct URL with api.securityscorecards.dev)
• README has OpenSSF Best Practices badge (correct PROJECT_ID, not placeholder)
• .github/workflows/ci.yml exists and uploads coverage
• .github/workflows/codeql.yml exists
• .github/workflows/scorecard.yml exists
• Codecov shows actual coverage percentage
• Scorecard shows actual score

If any badge shows "unknown", "invalid", or placeholder ID - FIX IT. Do not proceed.

OpenSSF Scorecard Optimization Playbook

Proven playbook to raise OpenSSF Scorecard from ~6.8 to ~9.0. Applied successfully on t3x-rte_ckeditor_image.

Check-by-Check Guide

Check	Quick Fix	Impact
Token-Permissions	Move all write perms from workflow-level to job-level	0→10
Branch-Protection	Set required_approving_review_count: 1 + auto-approve + protect release branches	0→8
Code-Review	Automatic after Branch-Protection fix	5→10
Security-Policy	Private vulnerability reporting + coordinated disclosure	4→10
Pinned-Dependencies	SHA-pin all actions (except SLSA generator — see below)	8→10
Fuzzing	Not practical for PHP/TYPO3 — skip	0 (accept)
CII-Best-Practices	Complete questionnaire at bestpractices.dev	2→6+

Token-Permissions (0→10)

The scorecard flags ANY write permission at the workflow-level. Fix: declare permissions: contents: read (or permissions: {}) at workflow-level, move all write to job-level.

# ✅ CORRECT
permissions:
    contents: read

jobs:
    deploy:
        permissions:
            contents: write    # only this job gets write
        steps: ...

# ❌ WRONG — Scorecard flags this
permissions:
    contents: read
    pull-requests: write       # write at workflow level!

Common violators: pr-quality.yml, release-labeler.yml, create-release.yml.

Branch-Protection (0→8) for Solo Maintainers

Solo-dev projects need required_approving_review_count >= 1 but can't wait for human reviewers. Solution: auto-approve workflow + ruleset.

Default branch ruleset:

gh api repos/OWNER/REPO/rulesets/RULESET_ID -X PUT --input - <<'EOF'
{
  "rules": [{
    "type": "pull_request",
    "parameters": {
      "required_approving_review_count": 1,
      "dismiss_stale_reviews_on_push": true,
      "require_code_owner_review": false,
      "require_last_push_approval": true,
      "required_review_thread_resolution": true
    }
  }]
}
EOF

Release branch ruleset (e.g., TYPO3_*, release/*):

gh api repos/OWNER/REPO/rulesets -X POST --input - <<'EOF'
{
  "name": "release-branches",
  "enforcement": "active",
  "target": "branch",
  "conditions": {"ref_name": {"include": ["refs/heads/TYPO3_*"], "exclude": []}},
  "rules": [
    {"type": "deletion"},
    {"type": "non_fast_forward"},
    {"type": "pull_request", "parameters": {
      "required_approving_review_count": 1,
      "dismiss_stale_reviews_on_push": true,
      "require_code_owner_review": false,
      "require_last_push_approval": true,
      "required_review_thread_resolution": true,
      "allowed_merge_methods": ["merge"]
    }},
    {"type": "required_status_checks", "parameters": {
      "required_status_checks": [{"context": "Build ✓", "integration_id": 15368}],
      "strict_required_status_checks_policy": true
    }}
  ]
}
EOF

Also enable enforce_admins via legacy API (scorecard reads this separately from rulesets):

gh api repos/OWNER/REPO/branches/main/protection/enforce_admins -X POST

Pair with pr-quality.yml auto-approve workflow (see github-project skill) that approves non-fork PRs via github-actions[bot].

Codeowner review incompatibility: require_code_owner_review: true is incompatible with bot auto-approve workflows. github-actions[bot] (GITHUB_TOKEN) is not a codeowner — its APPROVED review does not satisfy the codeowner requirement, permanently blocking all PRs. Verified on t3x-rte_ckeditor_image#629. Keep this false when using auto-approve.

Unresolved review threads: required_review_thread_resolution: true will block merge if automated reviewers (Gemini Code Assist, Copilot) leave unresolved threads. Resolve via:

gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "PRRT_xxx"}) { thread { isResolved } } }'

Remaining scorecard warnings (unfixable for solo maintainer):

• required approving review count is 1 — scorecard wants >= 2, impractical without human reviewers
• codeowners review is not required — incompatible with bot auto-approve (see above)

Security-Policy (4→10)

The scorecard requires SECURITY.md with:

1. Link to private reporting mechanism (not public issues!)
2. Response timeline (e.g., 48h acknowledgment, 7d fix)
3. Coordinated disclosure process

Template:

## Reporting a Vulnerability

**Please do NOT report security vulnerabilities through public GitHub issues.**

Instead, use [GitHub's private vulnerability reporting](https://github.com/ORG/REPO/security/advisories/new).

We will acknowledge receipt within 48 hours and aim to provide a fix
within 7 days for critical vulnerabilities.

## Coordinated Disclosure

After a fix is released, we will:
1. Publish a GitHub Security Advisory
2. Credit the reporter (unless anonymity is requested)
3. Include the fix in the next release with a CVE identifier if applicable

Enable private vulnerability reporting:

gh api repos/OWNER/REPO/private-vulnerability-reporting -X PUT

SLSA Generator Pinning Exception

The slsa-framework/slsa-github-generator reusable workflow cannot be SHA-pinned. It MUST use @vX.Y.Z tags — the slsa-verifier needs the tag to verify trusted builder identity. This is a known GitHub Actions limitation tracked as slsa-verifier#12.

Accept this as an unavoidable Pinned-Dependencies gap (score stays at 8, not 10).

Checks Not Worth Fixing

Check	Why Skip
Fuzzing (0)	OSS-Fuzz doesn't support PHP/TYPO3; ROI too low
Packaging (-1)	TER publishing isn't detected as a packaging workflow
Signed-Releases (-1)	Detection issue — SLSA provenance exists but isn't recognized

Assessment Workflow

1. Discovery: Identify platform (GitHub/GitLab), languages, existing CI/CD
2. Scoring: Apply checklists from references based on stack
3. Badge Assessment: Check OpenSSF criteria status
4. Gap Analysis: List missing controls by severity
5. Implementation: Apply fixes using scripts and templates
6. Verification: Re-score and compare (see Post-Implementation Verification)

---

Post-Implementation Verification

MANDATORY: After implementing improvements, re-assess the project to verify gains.

Re-Scoring Workflow

1. Record baseline score before making changes (save output)
2. Implement improvements following gap analysis priorities
3. Re-run full assessment using same criteria
4. Compare scores and document delta

Verification Checklist

Check	Before	After	Delta
OpenSSF Scorecard	_/10	_/10	+_
Best Practices Badge	Level	Level	Upgrade?
Coverage %	_%	_%	+_%
Enterprise Score	_/100	_/100	+_

Expected Outcomes

Implementation	Expected Score Impact
Add CI/CD workflows	+10-15 pts
Enable Codecov	+5-10 pts
Add CodeQL/Scorecard	+10-15 pts
SLSA provenance	+5-10 pts
Documentation (SECURITY.md, etc.)	+5-10 pts

Verification Commands

# OpenSSF Scorecard (re-run after changes merged to default branch)
scorecard --repo=github.com/ORG/REPO --format=json

# Coverage (after CI runs)
# Check Codecov dashboard or badge

# Best Practices (update at bestpractices.dev after implementing)
# Re-answer questions that are now satisfied

If score did not improve as expected, investigate:

• Did CI workflows run successfully?
• Are badges pointing to correct repository?
• Did changes merge to default branch (required for Scorecard)?

---

Continuous Improvement

Enterprise readiness is not a one-time achievement. Maintain scores over time.

Scheduled Re-Assessment

Frequency	Scope	Trigger
Weekly	Badge status check	Automated (CI)
Monthly	Scorecard re-run	Scheduled workflow
Quarterly	Full enterprise assessment	Manual or milestone
Per-release	Supply chain verification	Release workflow

Automated Monitoring

Add badge health check to CI:

# .github/workflows/badge-health.yml
name: Badge Health Check
on:
  schedule:
    - cron: '0 6 * * 1'  # Weekly Monday 6am
  workflow_dispatch:

jobs:
  check-badges:
    runs-on: ubuntu-latest
    steps:
      - name: Check Codecov
        run: |
          BADGE_URL="https://codecov.io/gh/${{ github.repository }}/graph/badge.svg"
          curl -sL "$BADGE_URL" | grep -q "unknown" && echo "::warning::Codecov badge shows unknown" || true

      - name: Check Scorecard
        run: |
          SCORE=$(curl -s "https://api.securityscorecards.dev/projects/github.com/${{ github.repository }}" | jq -r '.score // "N/A"')
          echo "Current Scorecard: $SCORE/10"
          if [ "$SCORE" != "N/A" ] && [ "$(echo "$SCORE < 7" | bc -l)" = "1" ]; then
            echo "::warning::Scorecard dropped below 7.0"
          fi

Regression Detection

Watch for these warning signs:

Signal	Detection	Response
Scorecard drop > 1pt	Weekly check	Investigate changed checks
Badge shows "unknown"	CI check	Verify token/configuration
CVE in dependency	Dependabot/Renovate	Priority update PR
Failed security scan	CI workflow	Block release until fixed
Coverage drop > 5%	PR check	Require coverage recovery

Dependency Update Cadence

Update Type	Frequency	Automation
Security patches	Immediate	Auto-merge if tests pass
Minor updates	Weekly	Renovate/Dependabot PR
Major updates	Monthly review	Manual approval required

Dependency CVE Workflow

When assessing enterprise readiness, always run dependency audit as part of discovery:

# PHP/Composer
composer audit

# Node.js
npm audit

# Python
pip-audit

# Go
govulncheck ./...

CVE Handling Best Practice

Separate dependency updates from code changes:

PR Type	Content	Why
Code changes	Business logic, bug fixes, features	Reviewable, testable in isolation
Dependency updates	composer update, version bumps	Clear diff, easy rollback if issues

Real-world example from t3x-cowriter review:

• Found 4 CVEs during enterprise assessment
• CVE fixes required composer update typo3/cms-core typo3/cms-backend
• Kept separate from code fixes (JS bug, AGENTS.md updates) for clean PR history

CVE Severity Response

Severity	Response Time	Action
CRITICAL	Immediate	Hotfix PR, expedited review
HIGH	24-48 hours	Priority PR, security review
MEDIUM	1 week	Normal PR cycle
LOW	Next release	Batch with other updates

CI Integration

Add dependency audit to CI pipeline:

# .github/workflows/ci.yml
- name: Security audit
  run: composer audit --format=plain

• One resource per test - No duplicate instances
• State mutation complete - Tracking fields updated after operations
• Defensive enum handling - Valid() method, default case, tested
• Documentation accurate - Claims match benchmarks, trade-offs noted
• Platform code marked - Limitations documented, alternatives provided
• Defensive code tested - Error paths and edge cases covered

Critical Rules

• NEVER interpolate ${{ github.event.* }} in run: blocks (script injection)
• NEVER guess action versions - always fetch from GitHub API
• ALWAYS use SHA pins for actions with version comments
• ALWAYS verify commit hashes against official tags
