Verdict

Task bugfix-cg-business-days-05 · Claude Code · Opus (external, code)

◐ Partial Evidence E3

failed: hidden_tests_pass

Agent claim (E0)

The agent said success: “businessDaysBetween started count at 1, so it overcounted by one on every call and returned 1 for equal days. Initialized count to 0 and simplified sign flip; all 11 tests pass.”

A claim is self-reported and never decides the verdict. Here the chain state contradicts the claim.
