src/pkgs/universal-router is a git submodule. The briefcase hex literal in UniversalRouterDeployer.sol was last regenerated against an old submodule pin that predated the v2.1.1 commit (PR #470 upstream). The monorepo's submodule pin has since advanced past v2.1.1, but no one re-ran ./script/util/create_briefcase.sh, so deploys via the briefcase were silently shipping v2.1.0 bytecode. This patch rewrites only the hex literal in UniversalRouterDeployer.sol with the v2.1.1 bytecode. The briefcase protocols/ source reference files are intentionally NOT touched in this PR — they're documentation and can drift relative to the deployer without affecting deployments. A follow-up can sync them when convenient. Bytecode diff: - Old size: 23,587 bytes - New size: 26,404 bytes (~12% larger) - Old keccak: 0x7171fed0bc0dd1a41b55969fe1ebdb60d3eeb80750c3fa8d7230ea06142db561 - New keccak: 0x6dba80c0116a490d48657845492bb38374489ed49c296ac50614265f97221510 v2.1.0 → v2.1.1 brings: - PAY_PORTION_FULL_PRECISION command (slot 0x07) with 1e18 precision - Per-hop slippage on v2/v3 swaps via minHopPriceX36 - minHopPriceX36 field on V4 ExactInputSingleParams struct - Command space expanded (mask 0x3f → 0x7f) - v2 fee-on-transfer slippage fix (uses actual balance change) - OZ audit fixes m01, l03, n05, n08 Verification: - forge build clean - New initcode keccak matches a fresh forge compilation of the current submodule pin's UniversalRouter source.

Summary
src/pkgs/universal-routeris a git submodule. The briefcase hex literal inUniversalRouterDeployer.solwas last regenerated against an old submodule pin that predated the v2.1.1 commit (PR #470 upstream). The monorepo's submodule pin has since advanced past v2.1.1, but no one re-ran./script/util/create_briefcase.sh, so deploys via the briefcase were silently shipping v2.1.0 bytecode.This PR is scoped to a single line change: the hex literal in
UniversalRouterDeployer.sol. Everything else the regen script touches (briefcase protocols/ source files, orphan hook scripts) is documentation/reference and can drift relative to the deployer without affecting any deployment — those follow-ups can ship separately when convenient.Diff
