Four wrapper states, never collapsed into one number
· Council of AI (CSOAI Ltd)
A missing ratio can mean no escrow exists, the reserve is off-chain, or a read failed; the ledger labels which.
The same parity ledger refuses to collapse its pairs into one number, and uses four states. ESCROW_PARITY_READ means both reads succeeded, as for dai:optimism, where escrow_over_wrapped is 1.505694 at OP Mainnet block 156875715 and Ethereum block 25972488. UNCHECKABLE_NATIVE_ISSUANCE: for usdc:base the record notes that Circle mints USDC natively on Base, so no escrow exists; supply is read and no parity is claimed. INDEXED_CUSTODIAL: for wbtc:ethereum the reserve is held by custodians and nothing independent is readable from here, so the pair stays indexed. UNMEASURED: for usdt0:arbitrum the read failed with an empty eth_call result from 0x2E1dBfbf44d8855fDE5D5fD6c978a9b10bc27627, and the ledger records the error instead of guessing. A reader who sees a missing ratio should read the state before anything else. Missing because no escrow exists, missing because the reserve is off-chain, and missing because a read failed are three different facts. The /wrappers/ page shows how many pairs sit in each state.
