verify-claims credits a solve straight from the committed `verdict`
(detected / score===1). Nothing asserted that a scored solve actually
agrees with its own committed flag oracle, so a hand-edited `detected:true`
(or a merge slip / fabricated placeholder flag) would pass verification
silently. The case-insensitive oracle comparator `ciMatch` was defined but
never called — this is exactly the check it was meant for.
Add an INTEGRITY GATE that re-derives, for every scored solve across the
pinned golden + white-box XBEN sweeps and the Cybench per-run artifacts,
that it is oracle-grounded: EITHER the self-reported flag matches the
committed `expected` (ciMatch), OR the harness auto-detected `expected`
verbatim in tool output (auto_detected, reported may be "UNKNOWN").
Anything scored that is neither is a phantom pass and fails the build.
Also rejects a fabricated placeholder credited via the self-report path,
and reports how much of the Cybench headline is backed by an oracle-bearing
per-run artifact vs. counted only in the hand-editable aggregate.
Adds src/__tests__/oracle-consistency.test.ts in the same spirit as
no-phantom-tools / stub-honesty: audits the committed artifacts AND proves
the gate has teeth against synthetic tampered/fabricated verdicts.
Current receipts pass clean: 0 phantom / 606 scored solves, 0 fabricated.
