Local analysis of the 2026-06-26 daily-triage validation failure: the unbounded
~1-recommendation-per-workstream list (16 active workstreams; JSON break at char
5268, ~rank 8-9) is the structural cause; both the first attempt and the retry
failed. The exact offending token and finish_reason are unrecoverable from
activity-core data — complete() drops finish_reason/usage, the report sink caps
raw output at 4000 chars (< 5268), and the log preview at 2000. Confirming the
exact token needs llm-connect producer-side logs on railiance01 (operator-owned);
mitigation (T02/T03) is identical regardless. Partial fixture captured.
