* feat(devops): migrate filesystem operations to io.Local abstraction Migrate config.go: - os.ReadFile → io.Local.Read Migrate devops.go: - os.Stat → io.Local.IsFile Migrate images.go: - os.MkdirAll → io.Local.EnsureDir - os.Stat → io.Local.IsFile - os.ReadFile → io.Local.Read - os.WriteFile → io.Local.Write Migrate test.go: - os.ReadFile → io.Local.Read - os.Stat → io.Local.IsFile Migrate claude.go: - os.Stat → io.Local.IsDir Updated tests to reflect improved behavior: - Manifest.Save() now creates parent directories - hasFile() correctly returns false for directories Part of #101 (io.Medium migration tracking issue). Closes #107 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * chore(io): migrate remaining packages to io.Local abstraction Migrate filesystem operations to use the io.Local abstraction for improved security, testability, and consistency: - pkg/cache: Replace os.ReadFile, WriteFile, Remove, RemoveAll with io.Local equivalents. io.Local.Write creates parent dirs automatically. - pkg/agentic: Migrate config.go and context.go to use io.Local for reading config files and gathering file context. - pkg/repos: Use io.Local.Read, Exists, IsDir, List for registry operations and git repo detection. - pkg/release: Use io.Local for config loading, existence checks, and artifact discovery. - pkg/devops/sources: Use io.Local.EnsureDir for CDN download. All paths are converted to absolute using filepath.Abs() before calling io.Local methods to handle relative paths correctly. Closes #104, closes #106, closes #108, closes #111 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * chore(io): migrate pkg/cli and pkg/container to io.Local abstraction Continue io.Medium migration for the remaining packages: - pkg/cli/daemon.go: PIDFile Acquire/Release now use io.Local.Read, Delete, and Write for managing daemon PID files. - pkg/container/state.go: LoadState and SaveState use io.Local for JSON state persistence. EnsureLogsDir uses io.Local.EnsureDir. - pkg/container/templates.go: Template loading and directory scanning now use io.Local.IsFile, IsDir, Read, and List. - pkg/container/linuxkit.go: Image validation uses io.Local.IsFile, log file check uses io.Local.IsFile. Streaming log file creation (os.Create) remains unchanged as io.Local doesn't support streaming. Closes #105, closes #107 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * docs(audit): add dependency security audit report Complete security audit of all project dependencies: - Run govulncheck: No vulnerabilities found - Run go mod verify: All modules verified - Document 15 direct dependencies and 161 indirect - Assess supply chain risks: Low risk overall - Verify lock files are committed with integrity hashes - Provide CI integration recommendations Closes #185 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * fix(ci): build core CLI from source instead of downloading release The workflows were trying to download from a non-existent release URL. Now builds the CLI directly using `go build` with version injection. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com> * chore: trigger CI with updated workflow * chore(ci): add workflow_dispatch trigger for manual runs --------- Co-authored-by: Claude Opus 4.5 <noreply@anthropic.com>

Supply Chain Assessment
Package Sources
- ✅ All dependencies from official Go module proxy (proxy.golang.org)
- ✅ No private/unverified package sources
- ✅ Checksum database verification enabled (sum.golang.org)
Typosquatting Risk
- Low risk - all dependencies are from well-known organizations:
- golang.org/x/* (Go team)
- github.com/spf13/* (Steve Francia - Cobra maintainer)
- github.com/stretchr/* (Stretchr - testify maintainers)
- cloud.google.com/go/* (Google)
Build Process Security
- ✅ Go modules with verified checksums
- ✅ Reproducible builds via go.sum
- ✅ CI runs
go mod verifybefore builds
Recommendations
Immediate Actions
None required - no vulnerabilities detected.
Ongoing Maintenance
- Enable Dependabot - Automated dependency updates via GitHub
- Regular audits - Run
govulncheck ./...in CI pipeline - Version pinning - All dependencies are properly pinned
CI Integration
Add to CI workflow:
- name: Verify dependencies
run: go mod verify
- name: Check vulnerabilities
run: |
go install golang.org/x/vuln/cmd/govulncheck@latest
