Every case, including the ones that went badly.

• 110 of 158

  right failures: the reported failure reproduced and captured, over the cases whose pinned commit still contains the defect. Over all 158 entries: 110.

  bench/external/scorecard.json, 2026-09-20

• 11 of 158

  wrong failures: a genuine signature captured for a failure the report never described. Worse than capturing nothing: the run holds real evidence for the wrong defect.

  bench/external/scorecard.json, 2026-09-20

• 0 of 158

  false successes: a claimed success sitting on top of a captured failure. The gate that counts these fails the build whenever the count moves.
