Created `.imd-findings.json` with no substantiated defects: ```json {"findings":[]} ``` Reviewed contracts, tests, ABI exports, and `launch.json`. All 61 Foundry tests pass, and exported ABIs exactly match compiled artifacts. No project files were modified.

I wrote `launch.json` at the repo root, and it's the only file changed. `forge build` succeeds, and `forge test` passes all 61 tests. Build and test don't exercise the manifest itself. I only confirmed it parses as JSON, and I didn't run it through the `LaunchManifest` schema. - **Token:** `DescentToken`, name "Descent", symbol "DSNT", 18 decimals. This matches `src/DescentToken.sol`, which has a zero-argument constructor and mints the whole supply to the deployer. - **Contracts:** one entry, `DutchAuction`, with `constructorArgs: ["$token"]`. That matches its single address-typed constructor parameter, `constructor(address token_)`. There are no `$owner` arguments, since the contract has no owner or admin, and there are no initialization calls. - **Pool:** ETH is the paired currency (zero address), fee 3000, tickSpacing 60, and initialPrice `79228162514264337593543950336`. I took these from the Sepolia values in the launch guidance, since nothing in the brief or code sets pool terms. The manifest has no hook field. - **Notes:** about 1,100 characters, well under the 4,000 limit. They describe the token, the auction rules, that no privileged role is granted, and that the price is a pool parameter, not a market valuation. The `initialPrice` lines up with a 1:1 raw ratio, and the notes call it that. Whether that suits the launch's supply split is a policy question for the services and reviewers.

Review complete. No substantiated defects found. Created [.imd-findings.json](/home/worker/.imd/seat2/work/0c556eed-ee68-43ca-9519-67ad93d1a2d4/543e1d23-696f-497e-91d9-d31abf1104f2/.imd-findings.json) with: ```json {"findings":[]} ``` All 61 Foundry tests pass, and both exported ABIs match the compiled contracts.

I've implemented the DSNT token and the `DutchAuction` contract, with tests, ABI exports and a README. `forge build`, `forge test` and `forge fmt --check` all pass offline, and all 61 tests pass. I also ran the two protected suites against my compiled bytecode in `test/scratch/`, using CREATE2 addresses I predicted myself. All 8 tests passed: token supply and decimals, no mint path, no forbidden opcodes, and the auction constructed with `$token`. `test/scratch/` is deleted, so it isn't in the delivery. **What's in the repo** - `src/DescentToken.sol` is a minimal ERC-20 with 18 decimals and a constant supply of 10^27 units. Its constructor takes no arguments and mints everything to the deployer. There is no mint, burn, owner or proxy path. - `src/DutchAuction.sol` takes only the token address in its constructor and has no owner, fee or admin. - `test/DescentToken.t.sol` and `test/DutchAuction.t.sol` hold the 61 tests, covering every path in the brief plus two fuzz tests. - `docs/abi/DescentToken.json` and `docs/abi/DutchAuction.json` are the ABI exports. - `README.md` documents the rules, assumptions, deployment parameters and who is responsible for what. - `foundry.toml` uses solc 0.8.26, `bytecode_hash = "none"`, no ffi and no filesystem access. - I vendored `forge-std` v1.9.7 into `lib/forge-std` as plain files, with no submodule. **Behaviour I chose where the brief left it open** - **Price:** it falls linearly from the start price to the floor and is quoted in wei per whole token. The whole lot costs `ceil(price × amount / 1e18)`, so a lot never costs zero. - **Timing:** buying is allowed up to and including the end time. Reclaiming is seller-only and only strictly after the end, so the two windows never overlap. There is no cancel before the end. - **Overpayment:** `buy` refunds any excess ETH to the buyer and reverts if the payment is short. I did this rather than requiring an exact amount because the price falls every second, so an exact-amount transaction would fail whenever it lands a block late. The contract never holds ETH. - **Escrow:** the lot must arrive in full, so a fee-on-transfer or false-returning token is rejected. - **Reentrancy:** state changes and events happen before external calls, and a reentrancy lock guards every entry point. - **Limits:** the floor must be above zero. Amount and start price must fit in 128 bits, and the end time must fit in 64 bits. **Tests** - **Success and failure paths:** creating, buying and reclaiming listings, with wrong amounts, unauthorized callers, unknown ids and double actions. - **Timing and pricing:** the exact end-time boundary, price monotonicity, and ETH conservation under fuzzing. - **Failing counterparties:** a seller that rejects ETH, a buyer that rejects the refund, and a token that returns false. - **Reentrancy:** attacks through a malicious token and through the seller's and buyer's ETH hooks, all blocked. **Left for later stages** - I didn't write `launch.json`. The README suggests the token and `DutchAuction` with `constructorArgs: ["$token"]` and no `$owner`. - The independent adversarial review is still required. Passing tests here is not an audit. - How the launch supply gets distributed is a launch-policy decision outside these contracts.
