+**Open tasks:**
+- ! Reproduce & Root-Cause The Failure  `74fd16a5`
+  *(wait: Local analysis complete: mechanism is the unbounded ~1-per-workstream recommendation list (16 active workstreams; break at char 5268 ~rank 8-9); both first attempt and retry failed. Exact token + finish_reason are unrecoverable from activity-core (complete() drops finish_reason; report cap 4000 < 5268; log cap 2000). Remaining: pull llm-connect producer-side logs on railiance01 (cluster/operator-owned). Does NOT block T02/T03 — mitigation is identical regardless.)*
