Added circuit breakers with configurable timeouts for all subsystems (APT, DNF, Docker, Windows, Winget, Storage). Replaces cron-based scheduler with priority queue that should scale beyond 1000+ agents if your homelab is that big.
Command acknowledgment system ensures results aren't lost on network failures or restarts. Agent tracks pending acknowledgments with persistent state and automatic retry.
- Circuit breakers: 3 failures in 1min opens circuit, 30s cooldown
- Per-subsystem timeouts: 30s-10min depending on scanner
- Priority queue scheduler: O(log n), worker pool, jitter, backpressure
- Acknowledgments: at-least-once delivery, max 10 retries over 24h
- All tests passing (26/26)
- Redesign AgentUpdatesEnhanced with tab-based workflow (pending/approved/installing/installed)
- Add AgentStorage component with disk partition table
- Add AgentScanners component for agent health monitoring
- Fix agent removal not refreshing list (cache invalidation)
- Bump agent version to 0.1.18 (enhanced disk detection)
- Update server default version to 0.1.18
- Add command source tracking (system/manual) migration
- Improve Linux disk detection for all physical mount points
