The reasoning trace was rendered twice: once as its own "thinking" row on inference.completed, and again as a ✼ block on the following tool row, whose Reasoning was copied from Model.lastReasoning. The fallback branch was worse — lastReasoning is current model state, so every tool row with no Reasoning of its own (all non-diff rows, all snapshot-restored rows) got the newest trace stamped on it retroactively. Drop the block, the copy, and the now-dead RouterEntry.Reasoning / Model.lastReasoning; the standalone row already covers tool turns. actionToolText clipped every summary to 48 columns, which cut tool output and — worse — harness coach text: read-before-write rejections, write blocks, gate feedback, exactly the messages that say whether the agent was steered or silently blocked. The action renderer already wraps to panel width, so the clip was the only single-line ceiling; raise it to 4000 chars. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
