I've read the brief. This is a panel-evidence NFT TWAP task: CryptoPunks sale-price TWAP over blocks 26027905–26035049, answer as uint256, recipe kind `panel`. Let me check the scan script and the imd-rpc skill.This is a panel-evidence NFT TWAP task. Key facts from the brief: - Window: blocks 26027905–26035049, chain 1, pinned toBlockHash `0xbd39...82ee`; time interval [1790018145, 1790104545) unix. - CryptoPunks native sales settle through the CryptoPunksMarket contract `0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb` emitting `PunkBought(uint256 indexed punkIndex, uint256 value, address indexed fromAddress, address indexed toAddress)` — that's the settlement event to scan (covers both `buyPunk` and bid accepts; wrapped-punk sales are excluded by scope). - Need a seed fill (latest qualifying sale ≤ start, within 7 days back), in-window fills, exclusions (zero-payment, buyer==seller), then last-sale time-weighted TWAP over 86400s. - Recipe must be `{"kind":"panel","source":<URL>}`; answer is uint256 decimal string. Let me set up a scratch workspace and verify the pinned block.Boundary confirmed: block 26027904 is at 1790018135 (< start 1790018145), so 26027905 is the first in-window block; 26035049 is at 1790104535 (< end). Now let me get the PunkBought topic0 and verify the pinned hash on a public endpoint.The keccak worked. My hex conversion may have been off — let me compute it properly and verify the pin.Head is 26035129 — past the pinned block. Now verify the pinned hash:Pinned hash confirmed on two operators. Now I'll write the TWAP computation script — it keeps logs in-process and prints only the summary.The script is running — the seed scan covers up to ~50k blocks backward. Let me wait for it.Computation complete: seed punk 6573 @ 31.98 ETH (406s before start), 35 qualifying in-window fills, TWAP = **34586394093413260355 wei** (~34.586 ETH). Two fills in tx `0x18d2514b...` show a same-tx resale (punk 8505) — I'll flag it in notes. Now let me attempt the OpenSea discovery/floor calls and CoinGecko for the contextual floor.OpenSea stats worked: floor 32.42 ETH. Let me get CoinGecko's floor figure for corroboration and timestamp the retrieval.CoinGecko corroborates floor 32.42 ETH and confirms the contract. Writing the answer now — note the window key order must match the brief exactly (`toBlock`, `fromBlock`, `toBlockHash`).Check passes. Let me independently re-verify the arithmetic from the saved fill CSV.Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: `34586394093413260355` wei (~34.586 ETH)** — the last-sale time-weighted TWAP. How it was computed: - **Pin verified**: block 26035049 hash `0xbd39...82ee` confirmed on two independent endpoints; window maps exactly to unix [1790018145, 1790104545). - **Settlement**: scanned `PunkBought` logs on the CryptoPunksMarket contract over blocks 26027905–26035049 — the native market emits it for both `buyPunk` and bid accepts, so it covers all paid native-punk settlements (wrapped punks are out of scope per the brief). 35 in-window fills, all qualifying (no zero-payment or buyer==seller). - **Seed**: punk 6573 @ 31.98 ETH at block 26027872, 406s before start — well inside the 7-day lookback. - **Integral**: 2988264449670905694685568 wei·s ÷ 86400 → floored to the answer. Recomputed independently from the saved CSV; matches. - **Flagged**: one tx resold punk 8505 twice in the same block (32.34 → 32.338 ETH); both kept, later logIndex wins per ordering rules. - **Context floor**: OpenSea stats `floor_price` = 32.42 ETH, CoinGecko corroborates 32.42 ETH / $89,247 (retrieved 2026-09-22T19:33Z) — context only, not in the TWAP. - **Limitation noted**: OpenSea events API returned 401 (no key), so discovery relied on the complete onchain log scan instead.
