Build a permissionless per-address token-bucket rate limiter: capacity 10 whole credits, refill 1 credit every 60 seconds, bucket initially full. consume(n) accepts 1..10 credits and affects only msg.sender. Preserve fractional refill time while below capacity; while full, excess refill is discarded. Specify timestamp accounting precisely.

Test repeated calls within one minute, long idle periods, saturation, partial refill and independent callers. Compare randomized call/time sequences with a …

    The deliverable is complete and committed on main as commit a0fbfbd. One part of the task could not be carried out: the Sepolia broadcast itself. Details below.

    What was built

    • src/RateLimiter.sol implements the permissionless per-address token bucket on Solidity 0.8.24. Each bucket is stored as a packed pair of missing credits and a refill anchor, so untouched storage reads as a full bucket. Below capacity the anchor advances only by whole intervals, which preserves fractional refill time. Once full, no time accrues, and the first consume from a full bucket restarts the clock at that timestamp. Errors carry the exact retry timestamp.
    • test/RateLimiter.t.sol holds 25 tests covering repeated calls within one minute, long idle periods, saturation, partial refill with fractional carry-over, independent callers, argument validation, error data, the overflow guard and the deploy script. Two fuzz tests replay randomized caller/delay/amount sequences against test/BucketModel.sol, a deliberately different "credit-seconds" model, comparing outcomes, available and availableAt after every step.
    • script/DeployRateLimiter.s.sol reads configuration from the environment in run() and hands it to a deploy() function the tests call directly. It refuses chain id 1.
    • README.md specifies the timestamp accounting rule by rule, lists assumptions, operational responsibilities and incomplete checks, and gives reproduction commands. DEPLOYMENT.md records parameters, encoded constructor arguments and the operator procedure.
    • forge-std v1.9.7 is vendored under lib/ as ordinary files, with no submodule.

    Verification

    CheckResult
    forge build --offline (fresh clone)passes, solc 0.8.24
    forge test --offline25 passed, 0 failed
    forge fmt --checkpasses
    forge script ... --offline dry runconstructor executes with (10, 60)

    How the earlier failures were avoided. The two rejected attempts pinned solc to a path, or left the compiler absent from the offline cache. This time every file carries an exact 0.8.24 pragma, no solc path is set, and solc 0.8.24 and 0.8.26 were downloaded into this machine's svm cache at ~/.local/share/svm so the offline build finds them. The protected harness files pin 0.8.26, so the compiler version is not forced in foundry.toml. That way they can compile alongside the project.

    Not done: the on-chain Sepolia deployment. This environment has no funded Sepolia account, RPC credential or keystore, and the contributor rules forbid a build task from using a wallet key or broadcasting. I did not fabricate an address or transaction hash. The deployment record in DEPLOYMENT.md has those fields marked as unfilled, with constructor arguments 10, 60, the ABI encoding, and the exact broadcast, verify and smoke-test commands an operator needs to finish it. No token was created, as the task instructed, so the token floor test will skip rather than run.

    writes to
    launch.json

    The manifest validates against the schema and refinements. The constructor ABI confirms two uint256 inputs, matching the "10", "60" arguments. Only launch.json is new in the working tree.

    Delivered: launch.json at the repo root, describing the accepted project.

    • RateLimiter is the single application contract, with constructor arguments ["10", "60"] for capacity and refill interval. These match the compiled ABI, the deploy script's demo config, and the README and DEPLOYMENT tables. No address arguments exist, so there are no $owner, $token or $contract references and no privileged wallet.
    • Pool pairs against native ETH with fee 3000, tick spacing 60 and the 1:1 sqrtPriceX96 opening price.
    • Notes describe the contract's behaviour, its lack of any admin path, and the local verification.

    One gap you must know about. The accepted tree contains no ERC-20, because the approved brief said not to create a token and the earlier builders honoured that. The evm_project schema still requires a token block, and I am restricted to writing only the manifest. I therefore named the token RateLimiterToken and stated plainly in the notes that no contract with that name exists in the source. The manifest is schema-valid, but attestation and deployment cannot succeed from this tree until either a builder assignment adds a fixed-supply token under that name, or the launch is re-scoped as token-less. The Token protected test skips when no token creation code is supplied, so the local floor does not catch this; the project floor would fail at the token deploy step.

    Verification run locally:

    forge build --offline   -> Compiler run successful
    forge test --offline    -> 25 passed, 0 failed, 0 skipped
    

    The schema and refinement check lived in test/scratch and is not part of the submission. No other file was changed. The Sepolia deployment record remains unfilled, as the earlier contributors documented, since no task in this chain may touch a wallet key.

    afterBuild contract project, Manifest

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

    • The launch manifest references nonexistent RateLimiterToken, blocking that deployment path.
    • Required Sepolia deployment evidence is missing.

    Both include concrete reproductions. No limiter accounting defect was substantiated. Existing project files remain unchanged.

    • mediumLaunch manifest references a nonexistent token and cannot deploy the approved projectlaunch.json:4

      The manifest selects RateLimiterToken, but the only application source is src/RateLimiter.sol and no RateLimiterToken implementation exists. Consequently, this manifest cannot be resolved to deployable creation code from the submitted tree. The pinned Project.protected.t.sol setup also requires token creation code before deploying application contracts, so omitting that artifact cannot satisfy that deployment path.

      The manifest notes acknowledge the gap but do not resolve it. Adding the proposed token would violate the explicit requirement not to create a token; the launch needs a deployment path compatible with the approved token-less scope, or an explicit scope decision outside this implementation.

      From the submitted repository, run forge inspect RateLimiterToken bytecode --offline --no-cache.

      It exits with status 1 and Error: No contract found with the name RateLimiterToken``.

      Read launch.json: token.contract is exactly RateLimiterToken.

      Expected: every manifest contract resolves to an existing deployable artifact and the deployment respects the no-token requirement.

      Actual: the required token artifact cannot be produced, blocking deployment through this manifest.

      This is independent of the successful unit tests of new RateLimiter(10, 60).

    • mediumRequired Sepolia deployment evidence is still missingDEPLOYMENT.md:77

      The requested deliverable includes deploying the tested RateLimiter to Sepolia, chain ID 11155111, and supplying its address, deployment transaction hash, explorer link and constructor arguments. The delivery explicitly records that no deployment was broadcast, leaves the address and transaction hash unfilled, and supplies only a placeholder explorer URL. Constructor arguments (10, 60) and an offline dry run are documented, but they do not establish a deployed instance.

      This remains an incomplete deliverable even if the manifest issue is resolved or the documented direct deployment path is used.

      Run sed -n '72,89p' DEPLOYMENT.md and git ls-files 'broadcast/*/11155111/*' against the submitted tree.

      The deployment table returns not deployed from this environment for both the contract address and transaction hash, the explorer link contains <CONTRACT_ADDRESS>, and there is no committed Sepolia broadcast record.

      Expected: a concrete Sepolia address and successful creation transaction, with an explorer link and constructor arguments 10 and 60 identifying the tested contract.

      Actual: no such address or transaction is supplied, so the required deployed instance cannot be verified.

      This reproduces the missing delivery evidence; it does not assert that no instance exists anywhere on Sepolia.
