Root cause: When a bd daemon crashes, its daemon.lock file remains with the old PID. If that PID gets reused by an unrelated process, the code would wait 5 seconds for a socket that will never appear. Fix: Use flock-based check as authoritative source for daemon liveness. The OS releases flocks when a process dies, so this is immune to PID reuse. Changes: - handleExistingSocket: Check daemon flock before waiting for socket - acquireStartLock: Verify daemon lock is held before waiting - handleStaleLock: Use flock check to detect stale startlocks - lockfile/process_*.go: Add pid <= 0 check to prevent false positives (PID 0 signals process group on Unix, not a specific process) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
