Review loop (--review-only, --all-reviewer, focused on this Mac: macOS, /usr/bin/python3 3.9.6, bash 3.2): round 1 (@63d8164) agy and grok PASS, claude and codex NOT PASS (F1 paho via the /usr/bin/python3 fallback, F2 logs default path, R1 disk-fallback redispatch interleaving, R2 symlinked registry), sent as a PR comment and fixed by the author in four commits; round 2 (@a7cb90e) 4/4 PASS. Full suite on macOS / Python 3.9.6 @a7cb90e: 1867 passed, 56 skipped, 1 error (the known #55 false positive: WAL/SHM of an agy conversation running in another workspace). Real herdr panes and ~/.claude/projects unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01VCgu9Fa9iT7TbJUSzdq4Ff
