Traced during UI-review verification: 50/50 live sessions are stuck
active/planning, never done/failed. Root cause confirmed against the
running DB — set_goal called once, propose_plan and complete_task
called zero times across all 50 sessions. The model consistently
skips the terminal complete_task call despite SOUL.md explicitly
instructing it to, especially for trivial single-tool Q&A turns.
Plan proposes an inline safety net for the common case plus an idle
sweep for structured goal/plan sessions that stall.
