chore: daily code review 2026-04-11

[alari76]

Summary

• Automated daily code review for 2026-04-11 (Codekin v0.6.0)
• Reviews last 7 days of changes including stepflow migration and PR review workflow addition
• 1 critical finding, 3 warnings, 3 informational notes

Key Findings

• [CRITICAL] Path traversal via symlink fallback in server/session-routes.ts — realpathSync failure silently falls back to path.resolve() which does not dereference symlinks, allowing boundary escape
• [WARN] No test coverage for commit-event-handler.ts, commit-event-hooks.ts, orchestrator-monitor.ts, version-check.ts
• [WARN] server/upload-routes.ts Multer config needs verification (size limits, MIME allowlist)
• [WARN] session-manager.ts (~1570 lines) and webhook-handler.ts (~800 lines) remain large — ongoing refactor recommended

Test plan

• Review critical path traversal finding and confirm fix approach
• Verify Multer configuration in upload-routes.ts
• Track test coverage additions for commit-event-handler and version-check
