- Add graceful shutdown validation - fail if buildkitd doesn't shutdown cleanly - Add sync after buildkitd termination to flush database writes - Add buildkit state validation before committing sticky disk - Prevent sticky disk commit on build failures - Add multiple sync operations before unmounting - Add buildkit validation utilities to check database integrity This should prevent the BoltDB corruption issues we've been seeing. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
