requirenonemptyfilescope: true # fail the judge loudly if the computed allowed-file set is empty
Root cause (LF-038, commit 91615fa5): the gitreins judge was configured with evaluator.file_scope: changed, which computes the set of files the evaluating LLM may read from the diff of the worker's commit. In this run, the task was created after the worker commit had already landed, so the diff against the task baseline was empty → the allowed-file set was empty. The LLM was permitted to read nothing, so it could not see the split barrel files it was asked to judge; it reported "split files did not exist" — a false FAIL caused by the evaluator's own file-scoping, not by the worker's output.
Fix: change the evaluator file scope from changed to full in .gitreins/config.yaml so the judge can read all repository files regardless of commit/task timing:
# .gitreins/config.yaml
evaluator:
file_scope: full # was: changed
# optional hardening so this class of failure is never silent again:
require_nonempty_file_scope: true # fail the judge loudly if the computed allowed-file set is empty
After the fix the task was re-run and completed with 8/8 PASS (commit d2ee936d).
Why changed broke here: file_scope: changed derives the readable file set from a git diff. That only yields the right set when the task pre-exists the worker commit (task → branch → commit). The task-created-after-commit flow (commit 91615fa5 → task created) leaves no diff to compute, so the scope degenerates to ∅. full is the correct, timing-independent scope for this pipeline.
When to use each:
| Scope | Correct use |
|---|---|
changed |
Task exists before the worker commit; you want to restrict the LLM to the touched files |
full |
Tasks are created after worker commits (this repo), or the judge must read barrel/index/split files adjacent to the diff to reason about them |
1. **False FAIL reproduced (commit `91615fa5`):** with `file_scope: changed` and a task created after the worker commit, the computed allowed-file set was empty. The judge's LLM could read zero files; it consequently fabricated the claim that the split barrel files did not exist → 8/8 FAIL. 2. **Fix applied:** `.gitreins/config.yaml` changed `evaluator.file_scope` from `changed` to `full`. 3. **Verification:** re-ran the task end-to-end → task completed with **8/8 PASS** (commit `d2ee936d`). The same worker output that previously failed now passes, confirming the failure was evaluator scoping, not worker content. 4. **Edge cases tested/considered:** - **Empty-scope guard:** added `require_nonempty_file_scope` check so any future re-occurrence (task/commit ordering regression, weird merge bases) fails loudly with a diagnostic instead of silently feeding the LLM an empty file set. - **Timing independence:** `full` scope works for both task-before-commit and task-after-commit orderings (superset of `changed`). - **Regression on other judges:** verified no other judge in the pipeline relied on restrictive `changed` scope as a security boundary; `full` only widens read access inside the already-checked-out repo, it does not relax worker execution or write scopes. - **Performance:** full-repo scope is acceptable here (small TypeScript barrel repo); for large monorepos a baseline-commit-diff scope would be the performance-tuned alternative, noted for future work.
