Measure native correctness chunks with executable repair pairs (sc-2500) - #598
Merged
Conversation
The correctness benchmark could not exercise production chunking, and repaired cases account for most clean-label blocks. This adds six executable repairs of existing defects, keeps 75 gold rows, and runs the native chunk/lens plan: 146 cases, 608 tasks and four chunked cases in one family at cap 400. Task recovery is bound to code, behavior and effective configuration; incomplete measurements cannot be accepted. Pair edges and whole-family uncertainty are reported separately. Final first-pass results: **71/75 defects blocked, 42/71 clean cases passed, 28/56 repairs passed, 25/56 pairs both correct**. The original 50 pairs score 21/50, previously 21/50. This is a methodology reset, not a model-quality improvement; Sol stays pinned and the 13.9% label-noise bound remains. Fixture development exposed real defects in the added reporting context. They were reproduced in controls and corrected identically across all four family members. The final run retains 142 unchanged cases and replaces the complete four-case family; prior invalid results and attempts remain retained. No unchanged quality miss was rerun. The detailed readout discloses both corrections, feedback exposure, quota recovery, task counts and interpretation limits. Validation: 26 latest focused tests pass; broader focused checks, typecheck and build pass. Full suite: 6,525 passed, 14 skipped, two untouched subprocess failures; both failing files pass all 23 tests in isolation. Managed ship gates run normally. Rebuilt distribution includes already merged sc-2493 capture code and Zod dependency. Other four reviewer suites retain immutable evidence marked stale under the shared runner/scorer change.

Set an explicit timeout above 150 seconds for the five-exercise tests.
The tests at indices 4 and 5 call exercise five times. Each child allows 30 seconds, which already reaches the shared Vitest testTimeout of 150 seconds. File setup and cleanup add time, and synchronous execFileSync prevents Vitest from interrupting a running call. Use a 180-second timeout for these it blocks.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the family row count before the loop.
rows.filter(...) can return an empty array if caseId is renamed or the family shrinks. The loop body then never runs and the control passes without executing any fixture. Assert the expected count, which the documentation states is four.
🐛 Proposed fix
- for (const row of rows.filter((r) => r.caseId === 'corr-reporting-command-family'))
+ const family = rows.filter((r) => r.caseId === 'corr-reporting-command-family');
+ expect(family).toHaveLength(4);

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
