`BridgeLedgerZero` is a substrate-fact-introduction candidate, not an autonomously authored predicate here. The existing `RatchetZero` variant does not fit today: runner evaluation is hard-coded to `compiler_std_positive_set_ratchet`, not a generic structural fold over rows.
`BridgeLedgerZero` is a substrate-fact-introduction candidate, not an autonomously authored predicate here. The `TestClaim.source` field is intentionally empty in this standby shape because the subject is the structural `ledger` declaration, not an executable source program. If the eventual runner requires a non-empty source string, that is a sign the predicate shape is wrong for this carrier and should be redesigned rather than filled with a dummy program. The existing `RatchetZero` variant does not fit today: runner evaluation is hard-coded to `compiler_std_positive_set_ratchet`, not a generic structural fold over rows.
