- PR #137176: fix(agent): notice identical successful replays whose fresh results defeat the streak
- PR #137177: fix(agent): block repeated successful tool calls

The three members concern an agent loop lacking a guard against repeating identical tool calls that succeed, including one report of 430 duplicate kanban_comment calls in one turn. Two are fix-titled changes aimed at blocking or detecting such repeats, including cases where fresh results would otherwise break the streak detection.
