Codex audit 2026-05-25 #5: after the `safe_compare_pred` fix patched per-record
`match` fields surgically, the top-level summary in every v22-v29 merged JSON
remained stale (each +1 inflated). This walks a list of report paths and
rewrites `overall.ea` + `overall.matched` from the truthful `records[]` array.
Idempotent: running twice leaves identical bytes.
