feat(RAN-54): land OpenSSF Best Practices passing + Scorecard hardening (#1)
Replicates the codeiq RAN-46 (B) OSS-CLI security recipe on snipIT, adapted for a single-file PowerShell 7.5+ project on .NET 9. PowerShell-specific delta: PSScriptAnalyzer added as the language-lint slot in security.yml (codeiq's SpotBugs equivalent); OSV-Scanner omitted because snipIT has zero external runtime deps (no npm / Maven / pip lockfile to scan). New files - .github/workflows/scorecard.yml ossf/scorecard-action v2.4.3, push to main + Mondays 06:00 UTC, SARIF -> Security tab - .github/workflows/security.yml trivy / semgrep / psscriptanalyzer / gitleaks / jscpd (powershell, --min-tokens 100) / SBOM (SPDX + CycloneDX). All actions SHA-pinned per Scorecard `Pinned-Dependencies`; top-level `permissions: read-all`. - .github/dependabot.yml github-actions ecosystem only (the only versioned dep surface in the repo today), weekly + grouped - SECURITY.md private-disclosure policy, supported versions, scope, hardening references - .bestpractices.json OpenSSF Best Practices self-assessment for project_id 12647 - CLAUDE.md agent brief: layout, build/test/run, conventions, OpenSSF Scorecard baseline + target, gotchas - shared/runbooks/engineering-standards.md PowerShell variant of the company canonical runbook - scripts/setup-git-signed.sh one-shot signed-commit setup (ssh / openpgp / x509) Modified - .github/workflows/test.yml pin actions/checkout by SHA, add `permissions: read-all`, drop the PSScriptAnalyzer job (moved to security.yml) - README.md OpenSSF Best Practices + Scorecard + Security workflow badges added at top Out of band (PR description tracks): - PATCH Paperclip Project `snipIT` codebase.repoUrl - Enable branch protection + Dependabot security updates on main - Mark Best Practices criteria `Met` on bestpractices.dev/projects/12647 (board admin OAuth required; .bestpractices.json already passing-level). Verified locally: yaml + json parse clean, headless tests 84/84 pass, PSScriptAnalyzer Error gate passes (49 Warning-severity findings — non-blocking per AC).
