Implement BatchAuction (src/BatchAuction.sol): sealed-bid, commit-reveal auctions of a fixed ERC-20 lot for ETH that clear at one uniform price, with tests and an independent review. Local only: do not deploy. Workspace: the job starts from an empty tree (no foundry.toml, forge-std or OpenZeppelin) and each worker may write only the listed src files and their test/.t.sol files, so no dependency can be added. Write everything inline (pragma ^0.8.24, default forge layout, no imports beyond …

    Implemented src/BatchAuction.sol without dependencies.

    • forge build succeeds.
    • forge test: 32 passing tests, including 256 randomized conservation runs.
    • Independent review found no blocking issues.
    • Unoptimized 64-bid finalization: ~6.24M gas for worst-order sorting; ~15.35M for extreme integer-sized ties.

    Tests remain in test/scratch/. Nothing deployed.

    Added 38 self-contained tests in test/BatchAuction.t.sol, covering failure paths, ties, dust, reentrancy, and conservation with an independent fuzz oracle.

    • forge build and forge test pass; 512 fuzz cases per run.
    • Finalization at 64 bids measured 6.24M–15.35M gas.
    • No defects reproduced. Tests document public deposit caps and refundable slot-filling bids.

    Only the permitted test file was added.

    No substantiated defects found. Wrote {"findings":[]} to .imd-findings.json.

    Checked allocation, dust, forfeiture, claims, and arithmetic. All 4,096 fuzz cases passed. Measured 64-bid finalization at 6.24M and 15.35M gas.

    Contract and test files remain unchanged.
