`artifacts/answer.json` is written (5944 bytes, valid JSON) and untracked, as required. ## What the answer says **Leader: `0xbac3aa3b91584a53a579b3c999a56756e954e59247e497bad1d25a4334bde551`** — the ETH/USDG pool (currency1 `0x5fc5…d168` = USDG, dynamic-fee flag `0x800000`, tickSpacing 10, hook `0x06a8…6080`), with **255.649 ETH** (`255649188357455367287` wei) of ETH-side volume over 305 swaps. Runner-up ETH/BORING did 77.28 ETH — a 3.3× margin, so the lead doesn't hinge on a single log. Five entries returned (`head` is 1); `recipe` is `v4-volume-rank` with exactly the catalogue's parameters: PoolManager `0x8366a39cc670b4001a1121b8f6a443a643e40951`, token `0x0`, `initializedSince` 9505, `topN` 5. ## How it was computed and checked - **Window pinned first.** All six listed endpoints returned `eth_chainId` `0x1237` and the pinned hash at block 68222605. (My first hex conversion of the block number was wrong; the corrected query matched on every endpoint.) - **Swap scan** over exactly 68204606–68222605: 38,360 `Swap` logs across 2,726 pools. Run three times on **three different operators** at three page sizes (ordofi @2000, blockmachine @900, official robinhood.com @1500) — **zero mismatches** on the pool set, per-pool sums, and swap counts, so no page was silently truncated. `robinhood-rpc.publicnode.com` refused the range as an archive request and was dropped. - **Pool currencies resolved twice, independently**: a full-history scan of `Initialize` filtered on `currency0 = 0x0` (416,630 native pools chain-wide), and a per-pool-id `Initialize` lookup for all 2,726 swapping pools. Both resolved all 2,726 and agreed on every one; no pool had `currency1 = 0x0`, consistent with v4's `currency0 < currency1` ordering. 1,440 pools have a native side, totalling 969.84 ETH. - **A decoding bug was caught and fixed**: `amount0`/`amount1` are `int128` but ABI-sign-extended into full 32-byte words. Decoding them as raw 128-bit values produced nonsense (~1e62 ETH) and a *different* ranking. The scanner now decodes each word as signed 256-bit and range-checks it to `int128`; both scans were re-run after the fix. - The builder script asserts request id, chain, window, and `answerType` are copied from the brief, that ids are lowercase bytes32, that the ordering and tie-break hold, and that the recipe carries no parameters outside the catalogue. Every definition the request left open — pool inclusion, what one Swap contributes, window inclusivity, ordering/tie-break, and the figure's units — is stated under `definitions` and used consistently.
