Agent evolver identified a systematic pattern:
- Pattern: Dead-end conflict handling in PR reviewer
- Evidence: When the reviewer detects merge conflicts, it posts a comment
saying 'implementor needs to rebase' and marks the PR as done. But the
issue worker has already exited after PR creation — nobody acts on the
rebase request. This created a dead end where 11+ approved PRs were
abandoned due to conflicts (PRs #1219, #1236, #1247, #1248, #1220,
#1237, #1238, #1246, #1252, #1269).
- Fix: When the reviewer reports a conflict, the pool supervisor (which
has full bash permissions and maintains a clone) now attempts to rebase
the PR branch onto latest master itself. If the rebase succeeds, the
PR is re-queued for merge. If it fails, the PR is abandoned with a
clear comment explaining manual intervention is needed.
This change requires human approval before taking effect.
