   "$comment": "GENERATED — the RETAINED ledger of check-engine-double-contract.mjs (#9680). Regenerate with `node scripts/check-engine-double-contract.mjs --write`; never hand-edit. Each row is one (file, verb) whose engine double routes through the producer's dispatch predicate. This is the OPPOSITE polarity to engine-double-contract.baseline.json: that ledger records DEBT and may only shrink, this one records COVERAGE and may only grow. A row that disappears is a pinned double that left the population — the blind spot #9680 measured, where deleting a double's delete() member took 319 pinned to 318 with the gate green. Read a removal in this file's diff as a coverage loss and check it was intended.",
