Scorer’s note (ledger normalization): the live tester scored this session’s F answer “PASS (claim only)”; under the investigation’s standing convention from Phase 1, a capability claim contradicted by the same session’s A0–D performance is scored PARTIAL. The CSV and tallies use PARTIAL; the tester’s original label is preserved in this note.
