Answer this question about chain 1 over blocks 26019450 to 26026606, exactly as .imd/reads/oracle.json pins it: What was the average sale price of SAVE ETH (contract 0x355919971b379ca9741ff29939c4ba716f873560) on OpenSea over the pinned 24-hour block window on Ethereum mainnet, in wei? Compute it from Seaport OrderFulfilled events on chain as the definitions say: every fill of exactly one ERC-721 token of the collection paid in ETH or WETH, price including fees, averaged over those sales and rounded down. Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
I'll start by reading the task inputs.Now let me read the two scripts to understand what's expected.I have the picture. The task: compute the average sale price of the SAVE ETH collection (`0x3559...3560`) from Seaport `OrderFulfilled` events over blocks 26019450–26026606 on mainnet, per the pinned definitions. The brief says `"evidence": "panel"`, so the recipe must be `{kind: "panel", source: <URL>}` — but the computation itself is on-chain log decoding, which `scan.mjs` can't fully express (nested item arrays), so I'll write a scratch decoder that applies the definitions exactly. Let me set up and check the environment.`OrderFulfilled` topic0 = `0x9d9af8e3...dcb6f31` — the standard Seaport topic. Now I'll write a scratch decoder that applies the pinned definitions exactly: chunked `eth_getLogs` with halving, ABI-decoding of `offer`/`consideration` item arrays, and the listing/bid price rules.Now run the scan — ~7,156 blocks of `OrderFulfilled` logs across both Seaport contracts.Clean result: 12,241 `OrderFulfilled` logs, 88 qualifying sales (47 listing fills, 41 bid fills), sum 3,640,742,690,000,000,000 wei → floor average **41,372,076,022,727,272 wei** (~0.0414 ETH). Pin hash confirmed on the endpoint. Now write `artifacts/answer.json`. Note: the checker compares `JSON.stringify(window)` to the brief, so I must keep the exact key order `toBlock, fromBlock, toBlockHash`.Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Result:** average SAVE ETH sale price over blocks 26019450–26026606 = **41,372,076,022,727,272 wei** (~0.0414 ETH). **How it was computed:** - `eth_getLogs` for `OrderFulfilled` (topic `0x9d9af8e3…b6f31`) on Seaport 1.5 (`0x…14dc`) and Seaport 1.6 (`0x…b395`) over exactly the pinned range, via `https://rpc.flashbots.net/fast` — chainId 1 confirmed, closing block hash matched the pin. - 12,241 `OrderFulfilled` logs decoded; 88 touched the collection `0x3559…3560`, and all 88 qualified (47 listing fills priced as the sum of ETH/WETH consideration including fees, 41 bid fills priced as the single WETH offer item). No bundles, ERC-1155, criteria, or other-token fills appeared. - Sum = 3,640,742,690,000,000,000 wei over 88 sales → `floor(sum/88)` = the answer. **Answer shape:** the brief's `"evidence": "panel"` requires a `panel` recipe, so `recipe.source` names the public RPC the fact was read from; the open definitions I fixed (NFT = itemTypes 2–5, listing vs. bid fill shapes, exclusions) are stated under `definitions`. The scratch decoder lives in `test/scratch/` and isn't part of the deliverable.
**41372076022727272** wei (≈0.041372 ETH) — mean of 88 qualifying Seaport 1.5/1.6 fills (47 listings, 41 WETH bids), sum 3640742690000000000 wei, over blocks 26019450–26026606; pinned hash confirmed on dRPC, publicnode and merkle. `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json` prints `ok`.
Created [artifacts/answer.json](/home/imd-worker/.identitymd/work/95b56ebd-edd6-4ef0-bbd6-545e538b8724/a1111c92-8c86-4c5c-8dc8-95757823d839/artifacts/answer.json). Average sale price: `41372076022727272` wei. The supplied checker prints `ok`.
I wrote `artifacts/answer.json`. The average SAVE ETH sale price over blocks 26019450 to 26026606 is **41372076022727272 wei**, from 88 qualifying sales totalling 3640742690000000000 wei. `check-answer.mjs` prints `ok`. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker requires a panel recipe for that. The recipe is therefore `{kind: "panel", source: <URL>}`. The steps that reproduce the figure are in `notes`. - **How I computed it:** - I used my own script in `test/scratch/run.mjs` rather than `scan.mjs`, because the answer needs the Seaport events decoded, not a plain sum or count. - I pulled every Transfer of the collection in the window (402 transfers across 287 blocks). Any sale has to move the token, so blocks without a Transfer can't hold one. - In those blocks I fetched Seaport 1.5 and 1.6 `OrderFulfilled` logs and decoded the offer and consideration items by hand, applying the brief's definitions. - No fills were excluded as bundles, other NFTs or non-ETH/WETH payments. - **Checks:** the closing block hash matched the pinned hash on both publicnode and mevblocker.io. The scan itself ran on publicnode alone, and there was no second full scan. - **Untracked:** git status is clean; `artifacts/answer.json` is untracked and `test/scratch/` is git-ignored. The previous attempt failed on an OpenAI 401 error, which doesn't apply here since this run made no OpenAI calls.
Created `artifacts/answer.json` with average **41,372,076,022,727,272 wei** across 88 qualifying sales, plus definitions and reproduction procedure. The required checker printed `ok`.
Wrote `artifacts/answer.json` with the reproducible calculation. Average: **41,372,076,022,727,272 wei** across **88 sales**. The required validator printed `ok`.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. The average sale price of SAVE ETH over blocks 26019450 to 26026606 is **41372076022727272 wei**. - **Sales counted:** 88 qualifying sales, 47 listing fills and 41 bid fills, with a total of 3640742690000000000 wei. The mean is 41372076022727272.72, rounded down. - **Scan:** I used a custom Node script rather than `scan.mjs`, which doesn't decode Seaport's `OrderFulfilled` arrays. It pulled `OrderFulfilled` logs from both Seaport contracts over the whole range and found 12241, with no duplicates. - **Chain check:** The endpoint (`ethereum-rpc.publicnode.com`) reported chain id 1 and returned the pinned hash for block 26026606. I did not check the hash on a second operator's endpoint. - **Recipe kind:** `oracle.json` says `"evidence": "panel"`, and the check rejects any other recipe kind for such a brief. The recipe is therefore `panel`, with the RPC call and log filter as its `source`, even though the figure comes from on-chain logs. - **Definitions:** `definitions` and `notes` state which fills count and how price is taken. - **Multi-fill transactions:** Each `OrderFulfilled` event counts as its own sale, so several fills in one transaction count separately. Many of the bid fills come from a few transactions that swept collection bids. The scan script is in `test/scratch/sales.mjs`, which isn't submitted. Nothing is committed.

Everything checks out — `artifacts/` is deliberately ignored by the workspace's `.git/info/exclude`, which matches the instruction to leave named outputs untracked for the daemon to upload. The task is complete. ## Summary **Answer: 41372076022727272 wei** (~0.0414 ETH) — the floor-average sale price of SAVE ETH (`0x355919971b379ca9741ff29939c4ba716f873560`) on OpenSea over blocks 26019450–26026606. How I got there: - **Scan**: fetched every `OrderFulfilled` event (topic `0x9d9af8e3…`) from Seaport 1.5 and 1.6 over exactly the pinned window from `https://rpc.flashbots.net/fast`, using a scratch Node decoder in `test/scratch/avg.mjs` (the stock `scan.mjs` can't decode Seaport's nested item arrays). It confirmed `eth_chainId` = 1 and the pinned closing hash before scanning, deduplicated by `blockNumber:logIndex`, and printed only totals. The pinned hash was also confirmed on a second operator (publicnode). - **Filter, per the brief's definitions**: of 12,241 `OrderFulfilled` logs in the window, 88 qualified — exactly one NFT item across offer+consideration, itemType 2, of the collection; listing fills priced as the sum of all consideration amounts (only when every consideration item is native ETH or WETH), bid fills priced as the single ETH/WETH offer amount, everything else excluded. - **Result**: 88 sales summing 3,640,742,690,000,000,000 wei → floor(sum/88) = 41,372,076,022,727,272 wei. This satisfies the `min: "1"` guard. - **Deliverable**: `artifacts/answer.json` copies the request id, chain, and window verbatim from the brief; the recipe is `{kind: "panel", source: "https://rpc.flashbots.net/fast"}` as required for an `evidence: "panel"` brief, with the full method in `notes` and the interpretive choices under `definitions`. `check-answer.mjs` prints `ok`, and the file is untracked as required. The previous seat's failure (a 401 from an OpenAI API call) was unrelated to the chain work — nothing here touched any external API beyond the public Ethereum RPCs.

I wrote `artifacts/answer.json` with an average sale price of **41372076022727272 wei**. `check-answer.mjs` prints `ok` for it. - **Result:** 88 qualifying sales over blocks 26019450 to 26026606 total 3640742690000000000 wei, and the mean rounded down gives the figure above. - **Exclusions:** no fills were excluded for being paid in another token. - **Method:** I fetched every Transfer log of the collection in the window (402 logs across 287 blocks). In each of those blocks I read the Seaport 1.5 and 1.6 `OrderFulfilled` logs and decoded them by hand against your definitions. Any sale of the collection also emits a Transfer, so filtering by block loses none. - **Endpoint:** all reads used `https://ethereum-rpc.publicnode.com`, and I confirmed chain id 1 and the pinned closing hash on it. I did not check a second operator. - **Scan script:** I did not use `scan.mjs`, because it can't decode the nested offer and consideration arrays. My script is in `test/scratch/run.mjs`, which isn't submitted. - **Recipe:** the brief says `"evidence": "panel"`, so the checker only accepts a `panel` recipe. I put the RPC endpoint and the `OrderFulfilled` topic in `source`, and the full method is in `notes`.
The average sale price of SAVE ETH over the pinned window is **41372076022727272 wei**, written to `artifacts/answer.json`. `check-answer.mjs` prints `ok`. - **Sales counted:** 88 qualified, 47 listing fills and 41 bid fills. Their prices sum to 3640742690000000000 wei, and 3640742690000000000 / 88 rounded down gives the figure above. - **Exclusions:** None of the collection's Seaport fills were dropped for a bundle, an ERC-1155 item or a payment token other than ETH or WETH. - **Window:** Blocks 26019450 to 26026606, with the closing hash confirmed as the pinned one. - **Method:** Instead of pulling every Seaport event, I fetched the collection's ERC-721 Transfer logs. There were 402 across 287 blocks, and every sale has one. I then decoded the OrderFulfilled logs from Seaport 1.5 and 1.6 for just those blocks (602 logs). - **Recipe:** The brief says `evidence: panel`, and the checker refuses any other recipe kind for such a brief. So the recipe is `panel`, with the RPC endpoint and the exact log query as its `source`, while the figure itself comes from chain data. The method is spelled out in `notes`. - **Endpoints used:** rpc.flashbots.net/fast, rpc.mevblocker.io/fast and one.valve.city. PublicNode refused archive reads. - **Scan script:** I used my own decoder in `test/scratch`, not `scan.mjs`, because `scan.mjs` doesn't decode Seaport's nested arrays. It isn't submitted. The only tracked or untracked change is `artifacts/answer.json`, left untracked.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` (exit 0). The file is untracked (gitignored), as required. **Answer: `41372076022727272` wei** (≈ 0.041372 ETH) — 88 qualifying sales totalling `3640742690000000000` wei. How I got there: - Confirmed `eth_chainId` = `0x1` and block 26026606's hash = the pinned `0x0f84a14c…a5fb2` on two independent endpoints (`ethereum-rpc.publicnode.com`, `rpc.flashbots.net/fast`). - `scan.mjs` over the pinned window: the collection emitted 402 `Transfer` logs across 287 blocks. Since a qualifying fill must move exactly one ERC-721 of the collection, every qualifying `OrderFulfilled` must lie in those blocks — so I read `OrderFulfilled` on both Seaport contracts in exactly those blocks (602 logs) and decoded each with the Seaport ABI. - Verified that shortcut rather than assuming it: all 22 sale transactions do emit collection `Transfer`s, and a full-range control scan of blocks 26020300–26021300 (3410 Seaport fills) yielded exactly the same 9 qualifying fills at the same prices as the candidate-block pass. - Result: 47 listing fills (42 ETH, 5 WETH; price = sum of all consideration, fees included) and 41 bid fills (WETH; price = the offer amount). All 88 on Seaport 1.6, none on 1.5. Nothing was dropped as a bundle, ERC-1155, or non-ETH payment — every `OrderFulfilled` in the window naming the collection qualified. Two things worth your attention, both stated under `definitions`: - **Matched pairs.** Five times, `matchOrders` emitted a bid log and the matching listing log for the same token id in the same transaction (10 of the 88). I counted each log once, following the brief's own event-level definition of a sale; collapsing them would require a rule the brief does not state. This is the one choice that could split the panel. - **Recipe kind is `panel`.** The brief sets `"evidence": "panel"`, and `check-answer.mjs` refuses any other kind for such a brief. It is also the only honest fit: `log-sum` adds a fixed data word per log, while `OrderFulfilled` carries price in dynamic arrays at a per-log offset, the collection is not an indexed topic, and an average needs a count as well as a sum. The `source` therefore names the exact RPC read that reproduces the number.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 41372076022727272 wei** (≈0.04137 ETH) — the mean, floored, of 88 qualifying SAVE ETH sales totalling 3640742690000000000 wei over blocks 26019450–26026606. How it was computed (a scratch Node script that printed only totals, never logs): 1. Confirmed `eth_chainId` = `0x1` and the pinned closing hash on two independent operators (publicnode, flashbots; a third on the rerun). 2. Pulled the collection's ERC-721 `Transfer` logs over exactly the pinned range — 402 transfers in 287 blocks — to locate every block a fill could be in. 3. Pulled `OrderFulfilled` (topic0 `0x9d9af8e3…`, verified with `scan.mjs --keccak`) from Seaport 1.5 and 1.6 for those 287 blocks: 602 events, 88 holding an ERC-721 of the collection. 4. Decoded the offer/consideration arrays and priced each per the brief: listing fills = sum of all ETH/WETH consideration (fees included), bid fills = the offer amount. All 88 qualified — no bundles, no non-ETH/WETH payment. 47 listings, 41 bids. The whole run was repeated over a disjoint endpoint set and produced identical counts and sums. Two judgment calls worth flagging, both stated under `definitions`: - The brief sets `"evidence": "panel"`, and the checker accepts only the `panel` recipe for such a brief — the chain recipes also can't express this question (`log-sum` sums one static argument; a Seaport price is a conditional sum over a dynamic array). So `recipe.source` names the exact public-RPC read (endpoint, block range, addresses, topic0, ABI) rather than an off-chain page, so the deployer reproduces it from chain data alone. - `figure` holds the summed wei behind the mean; the mean itself is `answer`. Scanning only blocks with a collection transfer yields the same event set as an unfiltered Seaport scan, since a fill always transfers the token — noted in `definitions.completeness` in case another panel member scans unfiltered.
Created `artifacts/answer.json`: **41,372,076,022,727,272 wei**, averaged across 88 qualifying sales, with reproduction instructions. Pinned block hash verified. Required checker printed `ok`.
The average OpenSea sale price of SAVE ETH over blocks 26019450–26026606 was **41372076022727272 wei** (about 0.0414 ETH). I wrote this to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **How it was computed:** I fetched every Seaport `OrderFulfilled` log in exactly the pinned blocks from both Seaport 1.5 and 1.6: 12,241 logs. The chain id and the pinned closing block hash matched on `ethereum-rpc.publicnode.com`, which served the scan. - **Sales found:** 88 qualify under the brief's definitions: 47 were listings bought outright and 41 were accepted bids. None were thrown out as bundles, ERC-1155 fills or payments in another token. - **Result:** the prices add up to 3,640,742,690,000,000,000 wei. Divided by 88 and rounded down, that gives the answer. A second full scan gave the same totals. - **Same token sold twice in one transaction:** this happens in five transactions. Each time a bot buys a listing and immediately sells the token into a lower bid. These are two real fills, so both count, as the definition says. I stated this in `definitions`. - **Recipe:** the brief marks this as a panel-evidence question, so the recipe is `{ kind: "panel", source: "https://ethereum-rpc.publicnode.com" }`. None of the chain recipe kinds can decode Seaport's item lists, so the deployer can't rerun this on chain. The method and the endpoints used are written up in `notes`. The decoding script lives only in `test/scratch/` and is not submitted. `artifacts/answer.json` is not tracked by Git, and I haven't committed anything.

`artifacts/answer.json` is written and untracked (as required), well under the 16,000-byte limit, and `check-answer.mjs` prints `ok`. Summary: scanned Seaport 1.5/1.6 `OrderFulfilled` logs over blocks 26019450–26026606 on Ethereum mainnet (12,241 logs total, filtered to the SAVE ETH collection per the pinned definitions), found 88 qualifying ETH/WETH single-ERC-721 sales summing to 3,640,742,690,000,000,000 wei, giving a floor average of **41,372,076,022,727,272 wei**. Since the brief is marked `"evidence": "panel"`, the answer uses the `panel` recipe kind (the only one `check-answer.mjs` allows for this brief) with `source` describing the exact on-chain read (contracts, topic, block range, decode/filter rules) so it can be reproduced.
Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 41372076022727272 wei** (~0.04137 ETH), the floor mean of 88 qualifying Seaport sales totalling 3640742690000000000 wei. How it was computed, over exactly blocks 26019450–26026606: 1. Pin confirmed on `https://ethereum-rpc.publicnode.com` (chain id 1, closing hash matches) and cross-checked on `https://eth.drpc.org`. The window spans 24.00 h of timestamps. 2. `eth_getLogs` for `Transfer` on `0x3559…3560` over the window: 402 ERC-721 transfers in 287 blocks. Every ERC-721 Seaport fill emits such a transfer, so those 287 blocks bound the search exactly. 3. `eth_getLogs` for `OrderFulfilled` on Seaport 1.5 + 1.6 in those blocks: 602 logs, decoded in-process (offer `SpentItem[]`, consideration `ReceivedItem[]`). 4. Applying the brief's definitions: 88 qualified — 47 listing fills (price = sum of all ETH/WETH consideration, fees included) and 41 bid fills (price = the single ETH/WETH offer amount), all on Seaport 1.6. None were dropped for bundles, ERC-1155, or a non-ETH/WETH payment. Min 0.032 ETH, median 0.04 ETH, max 0.149 ETH. Decoding was validated independently: for every native-ETH listing transaction the decoded price sum equals the transaction value (including a 22-fill sweep at 943086690000000000 wei), or falls just under it where the buyer was refunded. Two things worth flagging: - The brief sets `"evidence": "panel"`, so the recipe must be `{kind: "panel", source}` — and indeed no chain recipe in the catalogue can express this: the collection, item types and amounts live in dynamic arrays inside the log data, not in topics, so `log-sum` can neither filter the collection nor sum a variable-length consideration list. The `source` names the exact `eth_getLogs` calls so the deployer can rerun it. - One genuine ambiguity: 5 of the 88 are the second log of a matched bid+listing pair for the same token in the same transaction. The brief defines a sale as the *event*, so I counted both. The other reading (83 sales) gives 41557550481927710 wei; both figures are stated in `definitions`/`notes`.
`check-answer.mjs` prints **ok**. The deliverable is at `artifacts/answer.json` (untracked, as required). **Answer: 41372076022727272 wei** (≈0.0414 ETH) average sale price. How it was computed: - `eth_getLogs` for the Seaport `OrderFulfilled` topic0 `0x9d9af8e3…cacdcb6f31` on both Seaport 1.5 and 1.6, over blocks 26019450–26026606 inclusive, decoded in-process (`test/scratch/seaport-avg.mjs`) — only totals printed. - 12241 `OrderFulfilled` logs in the window; **88 qualify** (all Seaport 1.6): 47 listing fills (NFT offered, every consideration item ETH/WETH, summed with fees) and 41 bid fills (ETH/WETH offered, NFT in consideration, offer amount taken). Zero fills touched the collection and were dropped for a non-ETH/WETH price or an odd shape. - Sum 3640742690000000000 wei / 88 = 41372076022727272 remainder 64 → floors to the answer. Min 0.032 ETH, max 0.149 ETH. Verification done: - Chain id 1 and the pinned closing hash confirmed on four endpoints from different operators before scanning; `rpc.flashbots.net/fast` (first in the row) 429s every `eth_getLogs` and was abandoned. - Truncation check: full scan repeated on `ethereum-rpc.publicnode.com` at 300 blocks/call vs `rpc.mevblocker.io/fast` at 2000 blocks/call — identical log count, sale count and sum. One judgment call worth flagging: the brief carries `"evidence": "panel"`, and the checker rejects any chain recipe on such a brief, so the recipe is `{kind: "panel", source: <the endpoint scanned>}` even though the figure is computed from chain data. No catalogue chain recipe can express a per-fill decoded price averaged over single-ERC-721 fills, so the full method is spelled out in `definitions` and `notes` instead. Every choice the request left open (unit of sale = one qualifying event, inclusive block bounds, WETH 1:1, exclusions, floor rounding) is stated under `definitions` and used consistently.

Done. `artifacts/answer.json` is written, passes `check-answer.mjs` (`ok`), and is untracked (`artifacts/` is gitignored, so it won't be committed; the daemon uploads it). **Answer: `41372076022727272` wei** (≈0.04137 ETH) How it was computed, over exactly blocks 26019450–26026606 (pin `0x0f84a1…5fb2` confirmed on `rpc.flashbots.net/fast`, where the scan ran, and on `rpc.mevblocker.io/fast`): - Fetched all 12,241 `OrderFulfilled` logs from Seaport 1.5 and 1.6 in 800-block chunks (no refusals), decoded the nested `offer`/`consideration` arrays with a dependency-free scratch script in `test/scratch/`. - 88 logs touch the collection; all 88 qualify (exactly one ERC-721 of the collection, no other NFT, paid in ETH/WETH): 47 listing-side fills, 41 bid-side fills, all on Seaport 1.6, across 22 transactions. - Sum 3,640,742,690,000,000,000 wei ÷ 88 = 41,372,076,022,727,272 wei (floored). Min 0.032 ETH, max 0.149 ETH, median 0.04 ETH. Two judgment calls, both stated under `definitions`: - **"On OpenSea"** — the pinned definitions filter only by Seaport contract, not by zone or fee recipient, so I applied no OpenSea-specific filter. - **matchOrders pairs** — 5 bid-side events share a tx and tokenId with a listing-side event. The pinned definition counts each `OrderFulfilled` log as a sale, so both halves are included. If the panel majority instead deduplicates those, their figure will differ; I followed the definition as written. Since the brief is `"evidence": "panel"`, the recipe is `{kind: "panel", source: <RPC URL + query>}`, with the full reproduction procedure in `notes`.

`artifacts/answer.json` is written and the check script prints `ok`. The answer is **41372076022727272 wei**, about 0.0414 ETH. - **Figure:** 88 qualifying sales summed to 3,640,742,690,000,000,000 wei. The floor of the mean is 41372076022727272. - **Scan:** I fetched all 12,241 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over blocks 26019450 to 26026606, then decoded and filtered them by the definitions in `.imd/reads/oracle.json`. The endpoint was `https://ethereum-rpc.publicnode.com`, which returned chain 1 and a closing block hash matching the pin. - **My own script:** `scan.mjs` can't decode Seaport's item arrays, so I wrote a decoder in `test/scratch/s.mjs`. That folder is deleted before submission, so the recipe can't point at it. - **Recipe:** the brief is marked `"evidence": "panel"`, so the check requires a `panel` recipe with a URL `source`. I named the endpoint and the block range there, and the exact method is in `notes` and `definitions`. - **Not done:** I didn't check the closing hash on a second operator's endpoint, and I ran only the one scan.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average sale price is **41372076022727272 wei**, about 0.0414 ETH. - **Sales:** 88 qualified over blocks 26019450–26026606, 47 listing fills and 41 bid fills, with a total of 3640742690000000000 wei. The answer is that total divided by 88, rounded down. - **Method:** I fetched the OrderFulfilled logs from both Seaport contracts and decoded the offer and consideration items myself, since the delivered scan script can't decode them. I kept fills with exactly one NFT overall, an ERC-721 of SAVE ETH, and priced them by the request's definitions. No fills of the collection were excluded as bundles, ERC-1155 or other-token payments. The scratch script is `test/scratch/sales.mjs`, and nothing is committed. - **Recipe:** The brief says `evidence: panel`, and the checker only accepts a `panel` recipe for that. The recipe is therefore `panel` with the RPC endpoint and log query as its source URL. The figure itself comes from chain data. `notes` and `definitions` record the exact method. - **Not done:** I used one endpoint, `https://ethereum-rpc.publicnode.com`, and did not run a second full scan or a second-operator hash check. On that endpoint the chain id is 1 and the closing block hash matches the pin.
