description: "Static conformance lint of a permissioned-EVM settlement contract (Solidity source or ABI) against six invariants: atomic PvP/DvP (paired-or-revert), no native-token/msg.value settlement dependence, a finality-hook/settlement event, a compliance-gate modifier preceding every value transfer, bounded participant-set loops, and upgradeability disclosure. Lightweight in-browser parse only, never solc, never a network call. v1 scope is source + ABI; bytecode/opcode heuristics are deferred. Not a security audit."
