engine: reviewer subagents previously kept running after the parent task was moved out of in-progress, paused, or globally paused — they spawn their own AgentSession outside `activeSessions`/`activeStepExecutors`, so the existing kill paths never reached them. Track them in a per-task `activeSubagentSessions` map (mirrored in TriageProcessor) and dispose on the same triggers as the main session. ReviewOptions gains `onSessionCreated` / `onSessionEnded` callbacks the executor and triage processor wire to register/unregister. droid-cli: probe timeouts (`validateCliPresence`, `validateCliAuth`, `runDroidProbe`) raised from 5s to 45s — observed cold-start is ~20s, so 5s reported the binary as missing even when present. Provider gains a `FIRST_LINE_TIMEOUT_MS` (60s) cold-start guard so a hung droid binary is reported with an actionable error instead of being indistinguishable from a slow-thinking turn. Fix the await race in `streamViaCli`: when SIGKILL destroys stdout mid-buffer, `rl` may never emit "close", so the promise also resolves on `proc.close` and forces `rl.close()` — prevents the engine's "executor did not unwind within 60s — hung subprocess".

@fusion/droid-cli
First-party Fusion pi extension package that routes pi provider requests through the droid CLI subprocess using stream-json NDJSON.
Provider
- Provider ID:
droid-cli - Binary:
droid(must be installed and authenticated on PATH) - Registration: package extension entrypoint in
index.ts
Capabilities
- Subprocess streaming bridge for text/thinking/tool events
- Model auto-discovery from Droid CLI at provider startup with in-process caching
- Session resume support (
--resume/--session-id) to avoid replaying prior turns - MCP schema bridge for exposing pi custom tools as schema-only definitions
- Tool mapping and break-early control so pi remains the tool executor
- Thinking effort mapping from pi reasoning options to Droid CLI flags
Development
pnpm --filter @fusion/droid-cli test
pnpm --filter @fusion/droid-cli exec tsc --noEmit
