Initial project scaffold: macOS package security audit tool

This commit establishes the foundation for a comprehensive security audit tool for macOS developer machines. It audits all installed software, detects vulnerabilities via OSV.dev, and provides Claude-powered mitigation recommendations. ## Architecture - System inventory collection (Homebrew, pip, npm, Go, Rust, apps) - CVE scanning via OSV.dev API (no auth, unlimited rate limits) - Claude integration (CLI or SDK) for mitigation analysis - JSON + HTML report generation - Full test suite (34+ tests, 7 benchmarks) - Production-grade linting (11 linters via golangci-lint) - Vulnerability scanning (govulncheck) - GitHub Actions CI/CD pipeline ## Key Components - cmd/audit/: CLI entry point - internal/inventory/: System inventory parsing - internal/security/: OSV.dev querying, Claude integration, audit logic - internal/report/: JSON and HTML report generation - scripts/collect-inventory.sh: Bash script for system enumeration ## MVP Features - Homebrew package scanning - Python/Node/Go/Rust ecosystem scanning - CVSS-based severity filtering - Claude-powered recommendations (update/replace/protect/monitor) - Makefile automation (test, lint, vulnerability checks) - Pre-commit hooks configuration ## Testing & Quality - 34+ unit tests with table-driven patterns - 7 benchmark tests for performance - 11 configured linters (staticcheck, gosec, revive, etc.) - Code coverage reporting - GitHub Actions CI (tests on Go 1.22 & 1.23) - Pre-commit hook framework ## Documentation - README.md: Full feature and usage documentation - QUICKSTART.md: 3-minute setup guide - TESTING.md: Testing and code quality guide - QA_SETUP.md: Analysis tooling reference - DATA_SOURCES_SPEC.md: Vulnerability data source documentation ## Data Sources - OSV.dev: Primary CVE database (1.8 day latency, no auth needed) - GitHub Advisories: Supplement for maintainer-created advisories - OpenSSF Scorecard: Trust signals (repo health/practices) - Homebrew Formulae API: Package metadata - CISA KEV: Active exploitation tracking ## Next Steps Phase 1 (MVP): Complete and tested ✓ Phase 2 (planned): Third-party app scanning, VirusTotal integration Phase 3 (planned): Historical monitoring, scheduled audits, webhooks Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
