Phase 2: SubProcess observability in DroneManager and DroneInspector
...
Adds real-time subprocess monitoring to the IDE via the callback-chain and
subscribe/broadcast socket patterns:
Shared types (packages/api):
- New subprocess.ts message types: SubProcessStat, RequestProcessStatsMessage,
SubscribeDroneMessage, UnsubscribeDroneMessage
- New socket events in socket.ts: requestProcessStats, subscribeDrone,
unsubscribeDrone (ClientToServer); drone:log, drone:status (ServerToClient)
Drone (gadget-drone):
- onRequestProcessStats handler calls SubProcessService.ps() + summarize(),
returns typed SubProcessStat[] with status detection (exitCode/killed)
Backend routing (gadget-code):
- SocketService: getDroneSessionByRegistrationId(), droneMonitorIndex map,
addDroneMonitor()/removeDroneMonitor()/broadcastToMonitors()
- CodeSession: requestProcessStats proxy, subscribeDrone/unsubscribeDrone
- DroneSession: broadcast drone:log + drone:status to monitor subscribers
in addition to existing chat-session routing
Frontend socket layer:
- SocketClient: requestProcessStats(), subscribeDrone(), unsubscribeDrone()
- drone:log + drone:status events forwarded to event bus
Frontend components:
- LogRenderer — reusable log rendering core extracted from LogPanel
- SubProcessTable — btop-style process table with status dots
- DroneMonitorGauge — canvas oscilloscope waveform (studio-equipment aesthetic)
- DroneMonitor — 3-gauge container (CPU/red, NETWORK/cyan, FILE I/O/green)
Frontend pages:
- DroneManager: live log streaming, SubProcessTable, DroneMonitor gauges,
1-second polling, auto-scroll log with pause-on-scroll-up
- Home/DroneInspector: process count summary, mini LogRenderer, navigate-to-manager link
Documentation:
- Updated gadget-drone/docs/subprocess.md Phase 2 section
- Updated gadget-code/docs/ui-design-guide.md Phase 2 section
- Updated docs/socket-protocol.md with new events, sequences, and patterns

Phase 1: SubProcess service and agent tool
...
Complete Phase 1 of subprocess management in gadget-drone:
- SubProcessService with graceful shutdown (SIGINT→SIGKILL), halt, getLog
- SubprocessTool with create/list/kill/killAll/halt/log commands
- Registered in agent toolbox for build/test/ship/develop modes
- Fixed missing {{process_management_block}} replacement in chat-session.ts
- 34 unit tests across service and tool
- Comprehensive documentation in docs/subprocess.md
