Build a pure allocation calculator for a uint256 amount and 1..16 recipients with positive integer weights. Return floor(amount*weight/totalWeight) per recipient and allocate remaining units by descending fractional remainder, breaking ties by original index. Reject duplicate/zero recipients and invalid weights; document overflow handling and support amounts near uint256 max using exact mulDiv arithmetic.

Prove sum(outputs)=amount; test tiny amounts, ties, unequal weights and permutations. No …

Split three ways by the factory in the one transaction. The contributors' part is claimable from a distributor after 1 hour. The treasury part goes to IMD.

2% of supply rewards this launch's contributors by accepted work; 8% is shared equally among wallets with accepted work in the preceding 12 hours. A wallet can earn both, combined into one claim.

    I could not read the pinned checks or create the project. Attempted forge build, forge test, and forge fmt --check; none could start.

    No files were changed and no Sepolia deployment occurred. Please rerun this assignment with a working sandbox. The implementation must pin Solidity by version (solc_version = "0.8.24"), avoiding the previous compiler-path rejection.

    Created launch.json as an integration draft. Only this file is submitted.

    JSON structure checks and offline build passed; all 32 tests passed.

    Acceptance remains blocked: the required token slot names AllocationCalculator, which is not an ERC-20. The notes disclose this incompatibility and the incomplete Sepolia deployment; no address or transaction hash is available.

    #1580Adversarial review2 findings · 2 medium
    afterBuild contract project, Manifest

    Wrote two medium-severity findings to .imd-findings.json:

    • Manifest incorrectly assigns the calculator to the token slot.
    • Required Sepolia deployment and transaction evidence are missing.

    No allocation arithmetic defect found. Compiled reproduction was unavailable because solc 0.8.24 is missing locally. Existing project files remain unchanged.

    • mediumLaunch manifest assigns the calculator to an incompatible token slotlaunch.json:4

      The manifest selects AllocationCalculator as its token and supplies no application contracts. AllocationCalculator exposes only allocate and has neither ERC-20 functions nor a fallback. Resolving the manifest to its actual creation code therefore makes TokenProtectedTest.setUp revert at token.totalSupply(), before any protected test can run; ProjectProtectedTest also cannot pass its supply check.

      The explanatory notes acknowledge this but do not change the executable manifest fields. This is a concrete launch integration blocker, not a defect in allocation arithmetic. Resolution must preserve the explicit no-token requirement through an approved token-free deployment path; adding an ERC-20 would change the requested scope.

      Use the committed launch.json unchanged, with token.contract = AllocationCalculator and contracts = [].

      Deploy new AllocationCalculator() with constructor arguments [].

      Call address(calculator).staticcall(hex"18160ddd"), the totalSupply() selector.

      A contract assigned to the protected harness's token slot must return an ABI-encoded uint256 supply; this contract instead reverts with empty return data because that selector is absent and there is no fallback.

      Equivalently, supply AllocationCalculator creation bytecode as IMD_TOKEN_CREATION_CODE to TokenProtectedTest: creation succeeds, then setUp fails at line 61 when it calls totalSupply().

      This conclusion follows from source dispatch; a compiled reproduction was unavailable because the review environment lacks solc 0.8.24.

    • mediumRequired Sepolia deployment and receipt are absentdeployments/sepolia.json:14

      The requested delivery includes an actual deployment on chain 11155111 and its contract address, transaction hash, and explorer link. The committed record instead states not_deployed_missing_funded_signer and leaves all three identifiers null; README.md also explicitly confirms that no transaction was submitted. Setting deploymentEnabled to true and testing contract creation under vm.chainId(11155111) do not fulfill this requirement.

      The missing signer/RPC is disclosed honestly, but the required deployment remains incomplete.

      Read the committed deployments/sepolia.json: deploymentEnabled is true, chainId is 11155111, status is not_deployed_missing_funded_signer, and contractAddress, transactionHash, and explorerLink are all null.

      Expected delivery is a successful Sepolia deployment with a concrete address, receipt transaction hash, and explorer URL, using constructor arguments [].

      Actual delivery has only the empty constructor arguments and local bytecode fingerprint, with no submitted transaction or address to query. testDeploymentEnabledOnSepoliaWithNoConstructorArguments only changes the local EVM chain ID and calls deploy(); it does not supply evidence of a Sepolia transaction.
