Re-point the USDat implementation at the PYUSDX MultiMint base and add the upgrade-only migration path: - USDat extends MultiMint/ForcedTransferable, exposes `migrate` (reinitializer) instead of `initialize`; production is upgrade-only behind the existing proxy - UpgradeUSDatBase: claim outstanding M yield (permissionless) then upgrade + migrate, registering held M as a replaceable alt-asset; drop the JMIExtension storage-layout reference (skipped) and allow the missing initializer - Reorganize interfaces under src/interfaces/ (IUSDat, IMTokenLike + isEarning) - foundry.toml: enable ast/build_info/storageLayout for OZ upgrade validation - Tests: PYUSDX swapIn/swapOut unit suite (wrap/unwrap, whitelist, freeze, pause, forced transfer, migrate, replaceAsset) and a mainnet-fork upgrade test asserting state, holder balances, role continuity, and M earning stop
- Remove lib/solady: vestigial from the M-extensions era; nothing in the compiled tree imports it (verified the build passes without it). - Remove lib/openzeppelin-contracts-upgradeable: OpenZeppelin is already vendored by PYUSDX (common/lib). Remap @OpenZeppelin and openzeppelin-contracts(-upgradeable) into PYUSDX's copies so our imports resolve to the same OZ the USDat inheritance chain (MultiMint -> Extension) already uses (upgradeable v5.3.0, contracts v5.5.0). - Update .gitmodules and foundry.lock accordingly. Full suite (54 unit + 4 fork) green against the PYUSDX-provided OZ.
