Answer 1

I've produced the solution. One important caveat about verification, plus the deliverable.

Status

The gitreins source tree (gitreins-poc referenced by the <tool> symlink) and evaluator.py are not present on this machine — I confirmed the symlink target is missing and a filesystem-wide search for gitreins/evaluator.py returns nothing. So I could not patch or execute the real code here; the fix is written against the behavior the problem description pins down (evaluator.py:544, config.yaml:65–70, etc.) and the verification steps are written as repeatable commands the operator runs on a host that does have gitreins.

Deliverable

~/SOLUTION.md — self-contained and directly usable, containing:

  1. Title + symptom summary — the exact failure chain.
  2. Root-cause analysis (4 failure modes):
  3. Committed changes read as “no implementation” — evaluator diffs working tree vs HEAD, so committed edits look empty.
  4. LLM evaluator confabulation (backslash-continuation claim at config.yaml:65-70, and the “unchanged” claim) — ignore unless the real bytes corroborate.
  5. Retry storm — task complete spawns background judge jobs on ~30–60s cadence; 4+ judges → load 348 → tier1 mass timeouts. Killing PIDs is insufficient; must delete the task record to break the loop.
  6. SIGTERM-immune children (rethinkdb-unittest, clang-tidy) leaving zombies → need kill -9.
  7. The fix:
  8. Correct ordering (mandatory): create the task before editing; keep the change uncommitted until complete.
  9. Code patch to re-baseline the evaluator at task-creation time instead of HEAD.
  10. Emergency kill station: pkill -9 -f '[g]itreins.*judge' (bracket patterns to prevent self-match), plus delete-task-record.
  11. Zombie sweep.
  12. Verification — checks that the change shows up in the baseline diff, that judge count stays 0 across two retry cadences, that zombie count is 0, and a confidence rule (“read the real file, not the LLM claim”).
  13. Root-cause elimination checklist and lessons (tier3 cppcheck/clang-tidy is the only reliable signal for config-only tasks).

No codebase edits were possible given the missing source tree. If you can restore gitreins-poc (or copy the repo here), I can apply the evaluator.py patch directly and run the 4.x verification steps for real.
