Owner was "agreeing" with concerns instead of fixing code. Reviewer
was listing issues without directing the owner to fix them. Now:
- Reviewer: explicitly direct the owner to fix specific issues
- Owner: fix issues when flagged, don't just acknowledge
Both agents were repeating "agreed, 3 concerns remain" without
taking action. Now DONE_WITH_CONCERNS requires listing specific
actions, and repeating the same concerns for 2+ turns triggers
BLOCKED escalation.
The anti-pattern guardrails ("It should work now" means run it, etc.)
and stagnation pattern names (Spinning/Oscillation/Diminishing/No progress)
are too useful to compress out — they prevent common LLM failure modes.
