`check-answer.mjs` prints **ok** (exit 0). ## Result **Average sale price: `19842674958333333` wei** (~0.01984 ETH), over 24 qualifying Seaport sales summing to `476224199000000000` wei. ### How it was computed All from public RPC over exactly blocks 26019452–26026608. Closing hash `0x84272223…` matched the pin on `rpc.flashbots.net/fast`, and I cross-confirmed it on `ethereum-rpc.publicnode.com` and `one.valve.city` (chain id `0x1` on all three). 1. `scan.mjs` for the collection's `Transfer` topic → 27 logs in 24 distinct blocks. 2. `eth_getLogs` for `OrderFulfilled` (topic0 `0x9d9af8e3…`) on Seaport 1.5 and 1.6 in those 24 blocks → 41 events. Restricting to those blocks drops nothing: any qualifying fill moves one of the collection's ERC-721s and so emits a `Transfer` in the same block. 3. Decoded `SpentItem[] offer` / `ReceivedItem[] consideration` and applied the brief's filters. 17 events carried no item of the collection; none were excluded for a second NFT, an off-shape fill, or payment in another token. 4. 24 sales — 14 listing fills, 10 bid fills, 24 distinct order hashes across 20 transactions, prices from 0.0136 to 0.05 ETH. `476224199000000000 / 24` floors to `19842674958333333`. ### The one judgment call worth flagging Two of the 24 events are the counter-order halves of matched pairs (blocks 26023099 and 26023101): same transaction, same token id, adjacent log indexes, one NFT transfer each. The brief defines a sale as *an OrderFulfilled event* meeting the item test, with a price rule given for both the listing and the bid side — so both halves qualify and I counted both. I recorded the alternative under `definitions.noDedup` for readers: collapsing each pair to its fee-inclusive half gives 22 sales, sum `448682199000000000`, average `20394645409090909`. This is the likeliest axis for panel disagreement. Since the brief is `"evidence": "panel"`, the recipe is `{kind: "panel", source}` — the check script rejects a chain recipe here, and none of the four chain kinds can decode Seaport's two dynamic item arrays and divide by a count anyway. Scratch decoder lives in `test/scratch/seaport.mjs`; only `artifacts/answer.json` was written, and it is untracked.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. **Answer:** 19842674958333333 wei, the average sale price of Drop Ded Gorgez over blocks 26019452 to 26026608. - **How I got it:** I pulled every Seaport 1.5 and 1.6 `OrderFulfilled` log in the window from `https://ethereum-rpc.publicnode.com`, 12,232 in all, and decoded each one's offer and consideration items. - **Sales found:** 24 fills matched the collection, and all 24 qualified. None were bundles and none were paid in a token other than ETH or WETH. - **Sum and mean:** the prices total 476224199000000000 wei, so the mean is 19842674958333333.5, rounded down. - **Pin check:** the closing block hash matches the pinned one on publicnode, and on `https://rpc.flashbots.net/fast`. - **Decoder:** `scan.mjs` can't decode Seaport's nested item arrays, so I used my own decoder at `test/scratch/run.mjs`. It isn't part of the submission. - **Recipe:** the brief has `"evidence": "panel"`, and `check-answer.mjs` requires the recipe to be `{kind: "panel", source}` in that case. I used the publicnode endpoint and the event topic as the source. The deployer can't rerun a panel recipe, so agreement rests on the other members reaching the same figure. The figure itself is derived from on-chain data, and `notes` says so. The earlier attempt failed because the `artifacts` directory didn't exist. I created it, and the file is untracked in git.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price is **19842674958333333 wei**. - **Sales counted:** 24 qualifying sales over blocks 26019452 to 26026608, none excluded. Their prices sum to 476224199000000000 wei, and dividing by 24 and rounding down gives the average. - **How I computed it:** I listed the collection's ERC-721 `Transfer` logs in the window (27 logs in 24 blocks). I then fetched Seaport 1.5 and 1.6 `OrderFulfilled` events in just those blocks (41 events) and decoded them by hand. I did not use `scan.mjs`, because it can't decode Seaport events; my script is `test/scratch/sales.mjs`. - **Endpoints:** I read from `ethereum-rpc.publicnode.com`. The pinned closing hash matched on it, and on `rpc.flashbots.net/fast` as a second operator. - **Recipe kind:** `oracle.json` says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for such a brief. The recipe is therefore `panel`, with the RPC endpoint and event topic as its source. As a result the deployer can't rerun it automatically, and agreement rests on the panel matching my figure. The previous attempt failed because the `artifacts` directory didn't exist, so I created it. The `window` object has to keep the brief's key order (`toBlock`, `fromBlock`, `toBlockHash`) or the checker rejects it.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. The average sale price is **19842674958333333 wei**. - **Result:** 24 qualifying sales over blocks 26019452–26026608, totalling 476224199000000000 wei, averaged and rounded down. None of the collection's fills was excluded. - **Method:** I scanned the collection's Transfer logs for the window (27 logs in 24 blocks), since every sale moves a token. For each of those blocks I pulled the Seaport 1.5 and 1.6 OrderFulfilled logs and decoded them under your definitions. Blocks with no collection Transfer can't contain a sale, so I didn't scan them for Seaport logs. - **Pin and endpoints:** The closing block hash matches the pinned one on both publicnode and flashbots. I read from publicnode, with flashbots as fallback. - **Recipe kind:** The brief says `"evidence": "panel"`, and the reference allows only the `panel` recipe for that. The recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}`. The computation itself is described in `notes`. - **Earlier failure:** The previous attempt failed because the `artifacts` directory didn't exist. It exists now, and the file is untracked, not committed. My scan script is in `test/scratch/`, which is deleted before submission.

I've written `artifacts/answer.json`. The average sale price is **19842674958333333 wei** (about 0.0198 ETH), and `check-answer.mjs` prints `ok`. **How I got it:** I pulled every `OrderFulfilled` log from both Seaport contracts (1.5 and 1.6) over exactly blocks 26019452 to 26026608. That was 12,232 logs in total, all from `https://ethereum-rpc.publicnode.com`. I decoded them with a small Node script in `test/scratch/` and applied the brief's definitions as written. - **Checks:** the chain id is 1, and the closing block hash matches the pinned hash on publicnode and also on `https://eth.drpc.org`. - **Result:** 24 sales qualified, 14 of them listing fills and 10 bid fills. No sale of this collection was excluded as a bundle or as paid in another token. The prices add up to 476224199000000000 wei (saved as `figure`), and 476224199000000000 ÷ 24, rounded down, is the answer. **Recipe:** the request is marked as panel evidence, so the checker only accepts a `panel` recipe. Its `source` names the RPC endpoint, the `OrderFulfilled` event, both Seaport addresses and the block range. The deployer won't rerun a panel recipe, but anyone can reproduce the answer from public RPC logs. **One judgement call:** two transactions each contain a matched pair of events, one on the bid side and one on the listing side. The brief's definition counts every qualifying event, so I counted both events in each pair. That gives 24 sales. If someone treats each pair as one sale, the average comes out differently. I've explained this in `definitions` and `notes`. `artifacts/answer.json` is the only deliverable file, and I've left it untracked as instructed.

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 19842674958333333 wei** (≈ 0.019843 ETH), from **24 qualifying sales** summing **476224199000000000 wei** over blocks 26019452–26026608. How it was computed: - Pin confirmed on two independent operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`): `eth_chainId` = 1 and block 26026608 hash = `0x84272223…f3f`. - `eth_getLogs` for the collection's `Transfer` topic over the window (2000-block chunks, halving on refusal) → 27 ERC-721 transfers in 25 txs; every Seaport 1.5/1.6 `OrderFulfilled` log in those receipts was ABI-decoded and tested against the brief's definitions. That candidate set is complete, since any qualifying fill must move the token. - 14 listing fills (ETH, fee-inclusive consideration sum) + 10 bid fills (WETH offer amount); 15 distinct token ids; min 0.0136 ETH, max 0.05 ETH. One event skipped (its NFT was another collection); none skipped for non-ETH payment, ERC-1155, bundle, or multi-item offer. - The whole decode ran twice, once per endpoint, with identical results. `scan.mjs` can't decode `OrderFulfilled`'s two dynamic tuple arrays, so the fetch/decode was a short script in `test/scratch/` that printed totals only. Two judgment calls are recorded in `definitions`, and the one that could move the number is also in `notes`: two transactions were Seaport order *matches* that emitted a bid event and its counter-listing event for the same token. The brief defines a sale as a qualifying event, so both are counted; collapsing each pair would give 22 sales and a mean of 20394645409090909 wei. The recipe is `{ kind: "panel", source: … }` because the brief carries `"evidence": "panel"` — the checker rejects a chain recipe here — so the reproducible procedure lives in `notes` rather than in a rerunnable recipe kind.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price is **19842674958333333 wei**. - **Sales:** I scanned Seaport 1.5 and 1.6 `OrderFulfilled` logs over exactly blocks 26019452–26026608. That was 12,232 logs, and 24 of them were qualifying sales of Drop Ded Gorgez under the pinned definitions. - **Total:** the 24 prices sum to 476224199000000000 wei, and dividing by 24 and rounding down gives the answer. - **Pin:** the closing block hash matched on `ethereum-rpc.publicnode.com`, and I did not cross-check it on a second operator's endpoint. I read logs from that endpoint, with `rpc.flashbots.net/fast` and `rpc.mevblocker.io/fast` as fallbacks. - **Method:** I used my own decoding script in `test/scratch/s.mjs` rather than `scan.mjs`. The catalogue's recipes can't decode Seaport's offer and consideration arrays, so the script isn't part of what the deployer reruns. - **Recipe:** the checker requires `kind: "panel"` with a `source` URL for this request, so the recipe is `{ kind: "panel", source: "https://ethereum-rpc.publicnode.com" }`. It does not reproduce the figure by itself. The `notes` field describes how I computed it.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price is **19842674958333333 wei**. - **Window:** blocks 26019452 to 26026608. The endpoint returned chain id 1 and the pinned closing hash `0x84272223…fbf3f`. - **Scan:** the provided `scan.mjs` can't decode Seaport's nested offer and consideration items. I fetched the `OrderFulfilled` logs from both Seaport contracts with a script in `test/scratch/s.mjs` and decoded them by hand. - **Result:** 12232 logs, of which 24 qualified. None were skipped as an unrecognised shape. The prices sum to 476224199000000000 wei, which divides down to the figure above. - **Recipe:** the brief is panel evidence, so the checker only accepts a `panel` recipe. I set it to the panel kind with `https://ethereum-rpc.publicnode.com` as the source. The deployer therefore can't rerun the calculation from the recipe, and the panel's agreement is the evidence. - **Cross-check:** I read from one endpoint only and did not check the closing hash on a second operator's endpoint. That is stated in `notes`.

Done. The deliverable is in place and passes the plane's own check. **Answer: 19842674958333333 wei** (~0.01984 ETH) — the average Drop Ded Gorgez sale price on OpenSea over pinned blocks 26019452–26026608. How it was computed: - Wrote a scratch scanner in `test/scratch/avg.mjs` (Node stdlib only, reusing the skill's keccak) that fetched every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly the pinned window via `eth_getLogs` on `https://ethereum-rpc.publicnode.com`, in 1000-block chunks, printing only totals. The closing block hash matched the pin on that endpoint and on a second operator (`https://rpc.mevblocker.io/fast`), and the computed topic0 matched the canonical OrderFulfilled hash. - Of 12,232 Seaport fills in the window, 24 qualified under the pinned definitions: exactly one ERC-721 of the collection and no other NFT, paid entirely in ETH or WETH — 14 listing fills (price = sum of all consideration amounts, fees included) and 10 bid fills (price = the single ETH/WETH offer amount). No zero-price fill qualified, so that edge case never arose. Sum 476224199000000000 wei ÷ 24, floored, gives the answer, which also satisfies the `min: "1"` guard. `artifacts/answer.json` carries the request id, chain, and window copied byte-for-byte from the brief, the `uint256` answer, a `panel` recipe (required because the brief declares `"evidence": "panel"`) sourcing the public RPC the logs were read from, definitions for the choices the request left open (wei denomination with WETH 1:1, one sale per qualifying event, the exact listing/bid fill shapes, the no-other-NFT rule), and notes with the full method. `check-answer.mjs` prints `ok`, and the file is untracked for the daemon to pick up — no tracked or configuration files were modified.

Done. `artifacts/answer.json` is written, the checker prints `ok`, and the file is untracked (not committed). **Answer: `19842674958333333` wei** (~0.01984 ETH average). How it was computed: - Fetched every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly blocks 26019452–26026608 (pinned hash confirmed), ABI-decoded the nested offer/consideration arrays, and applied the brief's definitions verbatim: exactly one NFT item, itemType 2 of `0x9c51…1c2d`, listing fills priced as the sum of all ETH/WETH consideration (fees included, all-ETH/WETH only), bid fills priced as the ETH/WETH offer amount. - Result: 12232 OrderFulfilled logs in the window, 24 qualifying sales (14 listing fills, 10 bid fills, all on Seaport 1.6), sum 476224199000000000 wei, floor(sum/24) = 19842674958333333. - A second run on a different operator (publicnode, different chunk size) matched the hash and every total exactly, ruling out silent `eth_getLogs` truncation. One note: the brief is `"evidence": "panel"`, so the recipe kind is `panel` with the RPC endpoint and query as `source`; the full reproduction method is in `notes` and the applied definitions under `definitions`. The scratch decoder lives in `test/scratch/seaport-avg.mjs`.

Created `artifacts/answer.json` with an average of **19,842,674,958,333,333 wei** across 24 qualifying sales, plus definitions and reproduction code. The required validator printed `ok`.

**19842674958333333 wei** (24 qualifying Seaport fills, sum 476224199000000000 wei / 24; 12,232 OrderFulfilled logs scanned over blocks 26019452–26026608, pinned hash confirmed on dRPC and publicnode). `check-answer.mjs` prints `ok`.

The average sale price is **19842674958333333 wei** (about 0.01984 ETH), from 24 qualifying sales totalling 476224199000000000 wei. I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. **How I got it:** - I fetched all 12,232 OrderFulfilled logs from both Seaport contracts over exactly blocks 26019452–26026608, using `https://ethereum-rpc.publicnode.com`. - The chain id and the pinned closing block hash matched on that endpoint and on a second one, `https://rpc.flashbots.net/fast`. - 24 of those events involved the collection: 10 bid fills and 14 listing fills. Every one had a single ERC-721 token paid wholly in ETH or WETH, so none were excluded. - The provided scan script can't decode Seaport's item lists, so I decoded them with a small Node script in `test/scratch/`, which is not submitted. **Recipe:** the brief marks this as a panel-evidence question, so the checker only accepts a `panel` recipe with a `source`. The source names the endpoint, the event topic, both Seaport addresses and the block range. The steps are in `notes`, and the choices the brief left open are under `definitions`. **Decision for you:** two transactions (`0xbdceabf9b5…` and `0x8122471eda…`) each look like one sale but logged two events, one from the buyer's offer and one from the seller's listing. The brief defines a sale as one event, so I counted both events each time. If other panel members treat each pair as a single sale, their answer would be 22 sales averaging **20394645409090909 wei**. I put that figure in `notes` so the difference can be seen if answers don't match. The answer file is left untracked, as required.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. **Answer:** the average sale price is **19842674958333333 wei**, about 0.0198 ETH. - **Sales counted:** 24 qualifying sales (14 listing fills, 10 bid fills), summing to 476224199000000000 wei. - **Scan:** I fetched every Seaport 1.5 and 1.6 `OrderFulfilled` log over exactly blocks 26019452–26026608. That was 12,232 logs, of which 24 were fills of exactly one ERC-721 of the collection paid in ETH or WETH. None were excluded as bundles, other-token payments or other shapes. - **Cross-check:** two operators, publicnode and flashbots, gave identical full-scan results. The closing block hash matched the pinned one on four endpoints. **Panel recipe:** the brief is `evidence: panel`, so the recipe has to be `{kind: "panel", source}`. The chain recipes can't decode Seaport's nested arrays anyway. I put the publicnode RPC URL and the log query in `source`. **Not the delivered script:** I didn't use the delivered `scan.mjs`, because it only sums flat data words. I wrote my own decoder in `test/scratch/sales.mjs`, which nothing submits. **Definitions and notes:** the open points (what counts as a sale, how price is taken for listing versus bid fills, WETH address, rounding) are under `definitions`. The endpoints used are named in `notes`.

Done. `artifacts/answer.json` is written and untracked (excluded via `.git/info/exclude`), and `check-answer.mjs` prints `ok`. **Answer: 19842674958333333 wei** (≈0.01984 ETH), the floor of 476224199000000000 wei over 24 sales. How it was computed, over exactly blocks 26019452–26026608: 1. Confirmed `eth_chainId` = 1 and the closing block hash matched the pin on `https://ethereum-rpc.publicnode.com`, then again on a second operator, `https://one.valve.city/rpc/vk_demo/evm/1`. 2. Pulled the collection's `Transfer` logs over the window: 27 logs, all 4-topic (ERC-721), in 24 distinct blocks. Since every ERC-721 fill moves the token, those blocks bound where a sale can live — which turns a full-window Seaport scan into 24 single-block queries. 3. Pulled `OrderFulfilled` from Seaport 1.5 and 1.6 in those blocks (41 logs), decoded the offer/consideration arrays, and applied the brief's definitions. All 24 fills touching the collection qualified — 12 ETH listings, 2 WETH listings, 10 WETH bids, all on Seaport 1.6. None was dropped as a bundle, ERC-1155, or foreign currency. Validation beyond the scan itself: - Both endpoints returned an identical set of 27 transfer logs (same block/log indices), so nothing was silently truncated. - Every decoded `consideration` array ended exactly at the end of its log data — a wrong stride or offset would not land there. - For the 9 pure-ETH listing fills that were the sole sale in their transaction, the decoded price equalled `eth_getTransactionByHash` `value` to the wei, confirming both the decode and that fees are included. One thing worth flagging: the brief is a chain question but carries `"evidence": "panel"`, and `check-answer.mjs` refuses any non-panel recipe under that flag. A per-fill Seaport average is also beyond what `log-sum`/`log-rank` can express, since the price sits in a dynamic array in the log data rather than in one summable argument. So the recipe is `{ kind: "panel", source: <endpoint> }`, with the full reproducible procedure — topics, filters, block set, decode, and the exclusion rules — spelled out in `notes` and `definitions`.
