The findings file is written and validated, and only allowed paths were touched (findings file and `test/scratch/`).\n\n**Entry files read:** `src/ClausFreeDrawHook.sol` in full and its one import `src/IClausTradeProgram.sol`. Runtime dependencies were resolved from mainnet via RPC and Sourcify exact-match sources, treated as untrusted evidence: ClausGovernance, the per-program adapter ComputeProtectedProgram, TradeExtensionHost, the ProtectedHook proxy and its implementation, the Chainlink VRFV2PlusWrapper 1.0.0, and the Uniswap v4 PoolManager.\n\n**What the contract does.** It is a trade program behind a fixed adapter. Receipts for swaps arrive through `onTrade`, which credits the recipient's share and 0.1% of the swap fee to a prize pot, backed by ERC-6909 ETH claims the adapter transferred first. The sponsor seals 4-hour rounds with a Merkle root of free entrants and pays for one VRF request per round. Anyone can settle the drawn index with a proof, claim for the winner, sweep expired prizes to the recipient, or push recipient fees out.\n\n**Findings written (3, none above low):**\n- **Low.** Claims transferred to the hook beyond what its counters account for are locked forever. No sweep exists for the surplus. Reproduced with a mock harness.\n- **Info.** Anyone can call `claim` and pre-empt the winner's `claimTo` destination. Funds still reach the winner.\n- **Info.** Trust assumptions with concrete failing states: the sponsor controls entrants and can make a round unsettleable, receipt delivery timing decides which round's pot absorbs a receipt, governance can switch the host module, the hook proxy's admin appears renounced, and Chainlink's wrapper owner can disable requests.\n\n**Verified properties.** Replay and receipt binding, the backing invariant (reserve only decreases through the hook's own burns), the payment lock, single VRF request per round with duplicate callbacks ignored, callback gas measured at about 35k against the 100k limit, exclusive time windows for late-pot assignment versus sweeping, and accounting conservation across seal, settle, claim, sweep and finish.\n\n**Candidates rejected by evidence.** A low-gas-limit griefing of fee collection is impossible by EIP-150 arithmetic, since the outer call cannot survive an inner out-of-gas. An in-swap `AlreadyUnlocked` failure does not occur because the host requires delivery outside the manager lock. A rounding-induced undeliverable receipt was ruled out by checking the live hook's fee math across 3 million consecutive and 200k random amounts.\n\n**Coverage limits.** The economics guides were applied in depth; the other nine specialties were lighter passes. Testing used an out-of-repo Foundry harness with mocks, not a mainnet fork, and no static analyzer ran. No code was modified, deployed, or signed.","treeHash":null,"usage":{"cachedInputTokens":2709457,"inputTokens":964,"model":"claude-fable-5-1","outputTokens":65911,"runtime":"claude","turns":47,"wallClockMs":919156}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"a43d0c18792c5628","findings":[],"hash":"770f53a558f35bb83c00542497d2f83d6e472e1be76e02d24f009546c754a9bb","nodeId":"84be7489-2869-4f0c-bb05-0a74a1cc06b0","outcome":"failed","summary":"could not materialize reads: read pinned:84be7489-2869-4f0c-bb05-0a74a1cc06b0:1: fetch failed","treeHash":null,"usage":{"cachedInputTokens":0,"inputTokens":0,"model":null,"outputTokens":0,"runtime":"codex","turns":0,"wallClockMs":2311}},{"artifacts":[],"attempt":1,"bundleHash":null,"device":"fea1c984a93ab45d","findings":[],"hash":"a305e35c36ca6e9e6e9124dbd14d900f8817a7cf17594977b36a7bab51e19235","nodeId":"84be7489-2869-4f0c-bb05-0a74a1cc06b0","outcome":"failed","summary":"Selected model is at capacity.
