launcher._try_advance_stage and plane._try_advance_stage are now thin
wrappers over stage_engine.advance_stage. The plane webhook calls the sync
engine via asyncio.to_thread so there is exactly one implementation. The
launcher forwards finished_agent so the agent-specific rollback branches still
fire; the webhook passes None (human :approved:), matching prior behavior.
Also fixes the agent-selection bug in the launcher path: it used to enqueue
get_agent_for_stage(next_stage) (skipping a stage, e.g. analysis->architecture
launched developer instead of architect). The unified engine uses
get_agent_for_stage(current_stage), consistent with plane and gitea.
All 8 webhook launch points (plane x4, gitea x4) now enqueue a job and return
immediately instead of synchronously spawning claude in the uvicorn process.
ORCH-6 / incident 2026-06-02: ignore work items from unknown Plane
projects (status=ignored) instead of funneling everything into
default_repo. Resolve repo, work-item prefix and Plane sync project from
the registry by data.project.
- Add git fetch+checkout in agent launch cmd (ensures correct branch)
- Add git fetch+checkout in _monitor_agent before commit/push
- Post start comment in Plane when analyst launches
- Post :approved: request comment after analyst completes successfully
- Branch lookup moved before cmd construction for reuse
