Answer this question about chain 1 over blocks 26019452 to 26026608, exactly as .imd/reads/oracle.json pins it: What was the average sale price of Human Resources by Tabor Robak (contract 0x88a409734e5997f1fda972cb1bb577e5b88c19da) 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
Created [artifacts/answer.json](/Users/zhuminquan/.identitymd/work/c63dee17-e968-4b29-afd3-84b28d7dcdb9/40d8886b-644b-4b0f-b35b-15054399b5fe/artifacts/answer.json). Computed average: `12325908260869565` wei across 23 sales. The required checker prints `ok`.
Created [artifacts/answer.json](artifacts/answer.json) with **12325908260869565 wei**, averaged over 23 qualifying sales, plus definitions and reproduction code. Required checker printed `ok`.
Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 12325908260869565 wei** (average), from **sum 283495890000000000 wei over 23 sales**. What I did: 1. **Pinned the chain first** — `eth_chainId` = `0x1` and `eth_getBlockByNumber(26026608)` = `0x84272223…7fbf3f` on two endpoints from different operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`). 2. **Found the candidate fills cheaply** — `scan.mjs` over the pinned window for the collection's ERC‑721 `Transfer` topic: 23 logs in 8 blocks, `pinned: true`. Every Seaport ERC‑721 fill emits that Transfer, so the 8 transactions holding them are a complete superset of the fills. 3. **Decoded the fills** — `scan.mjs` can only sum fixed data words, and an `OrderFulfilled` price sits inside two dynamic arrays, so I decoded the receipts in `test/scratch/` (reusing the script's `keccak256` and its halve-on-refusal `eth_getLogs`). 23 `OrderFulfilled` logs, all Seaport 1.6, each offering exactly one ERC‑721 of `0x88a4…19da` against exactly two native‑ETH consideration items (proceeds + one fee), both summed. No bids, no WETH, no bundles, no ERC‑1155, nothing excluded by the price rule. 4. **Ran it whole on both endpoints** — identical totals. Floor of 283495890000000000/23 drops a 5 wei remainder. Two things worth flagging: - The brief sets `"evidence": "panel"`, so the catalogue allows only `{kind: "panel", source}` — `log-sum` genuinely cannot express this figure. The `source` therefore names the exact calls, contracts and blocks rather than a page, so it reproduces from public RPC alone; the reasoning lives in `notes`. - `figure` is the sum (283495890000000000); the answer itself is the average. Where the request left a choice open — offer-shape for listing vs bid, ETH/WETH parity, one sale per log rather than per transaction, inclusive endpoints — it's stated under `definitions` and applied consistently. The file is left untracked, and `test/scratch/` holds the decode script.

Done. The answer is **12325908260869565 wei** (~0.01233 ETH), written to `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. How it was computed: - Scanned `eth_getLogs` for the Seaport `OrderFulfilled` topic (`0x9d9af8…6f31`) on both Seaport 1.5 and 1.6 over exactly the pinned window, blocks 26019452–26026608, from `https://ethereum-rpc.publicnode.com`. The endpoint reported chain id 1 and the closing block's hash matched the pin; I also confirmed the pinned hash on a second operator (`rpc.mevblocker.io`). - A small scratch decoder (`test/scratch/compute.mjs`) parsed each log's offer/consideration arrays and applied the brief's definitions verbatim: of 12232 `OrderFulfilled` logs in the window, 23 touched the collection `0x88a4…19da`, and all 23 qualified — every one a listing fill of exactly one ERC-721 with all consideration items in native ETH or WETH. There were no bid fills, no bundles, and no fills excluded for other payment tokens. - Sum of prices including fees: 283495890000000000 wei; floor(sum / 23) = 12325908260869565. On the answer's shape: the brief declares `evidence: "panel"`, and the checker enforces that a panel-evidence question use the `{kind: "panel", source}` recipe — none of the four chain recipes can decode Seaport's nested item arrays anyway. So the recipe names the RPC endpoint as `source`, the `definitions` block pins every choice the question left open (no OpenSea fee-recipient filter, the exact listing/bid fill shapes, WETH-only itemType 1, floor rounding), and `notes` records the full reproducible procedure. The window was copied with the brief's exact key order, which the checker compares byte-for-byte. `artifacts/answer.json` is untracked, as required, for the daemon to pick up.
The average sale price was **12325908260869565 wei** (about 0.01233 ETH), from 23 qualifying sales totalling 283495890000000000 wei, rounded down. The answer is in `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. **How I got it** - **Scan:** I pulled every `OrderFulfilled` log from both Seaport contracts over exactly blocks 26019452–26026608, 12232 logs in total. I used `https://ethereum-rpc.publicnode.com`, which returned chain id 1 and the pinned closing block hash. I also confirmed that hash on `https://rpc.mevblocker.io/fast`. - **Decoding:** The provided `scan.mjs` can't decode Seaport's item lists, so I decoded them with my own Node script in `test/scratch/` (not submitted). I applied the request's definitions as written: exactly one ERC-721 of the collection and no other NFT; for a listing, the sum of all ETH/WETH consideration amounts including fees; for a bid, the offer amount. - **Result:** 23 logs involved the collection and all 23 qualified. Most came from a few multi-listing purchases in blocks 26026555–26026585, and each fill counts as one sale, as the definitions say. **Decisions and limits** - **Recipe kind:** The request says `"evidence": "panel"`, so the recipe is the `panel` kind, with the RPC endpoint I read from as its `source`. Nothing reruns it; the check is agreement across the panel. - **Counting:** Every event counts once. If one trade ever showed up as two matched orders it would be counted twice, but none did here. - **Not verified:** I didn't record whether each fill was a listing or a bid, or whether it was paid in ETH or WETH. The notes only claim what the script checked. I ran one full scan, as the task guidance says one is enough. `artifacts/answer.json` is left untracked, as the task asks.
I wrote `artifacts/answer.json`. The average sale price of Human Resources over blocks 26019452–26026608 was **12325908260869565 wei**, about 0.01233 ETH. `check-answer.mjs` prints `ok`. - **Sales:** 23 qualifying fills, summing to 283495890000000000 wei. No fills were excluded as bundles or as non-ETH/WETH payments. - **Method:** I pulled every `OrderFulfilled` log from Seaport 1.5 and 1.6 over the pinned blocks from `https://ethereum-rpc.publicnode.com` (12,232 logs). I decoded them by hand in a custom script and kept the single-ERC-721 fills of the collection. The scan script can't decode Seaport's nested event data, so I didn't use it. - **Counting:** each log counts as one sale, so several fills in one transaction count separately. Several of the 23 sales share a transaction hash and price, for example six at 0.011 ETH in one transaction. - **Pin check:** the closing block hash matches the pin on publicnode and on `https://rpc.flashbots.net/fast`. - **Recipe:** because the brief's evidence type is `panel`, the recipe is `{ "kind": "panel", "source": "https://ethereum-rpc.publicnode.com" }`. The catalogue's chain recipes can't express a decode-and-average anyway. The full method is in `notes` and the definitions are stated under `definitions`. The scratch script is `test/scratch/sales.mjs`; it isn't submitted.

The average sale price was **12325908260869565 wei**, about 0.01233 ETH. This is the mean of 23 qualifying sales totalling 283495890000000000 wei, rounded down. `check-answer.mjs` prints `ok` for `artifacts/answer.json`. - **Window:** blocks 26019452 to 26026608. I confirmed the chain id is 1 and that block 26026608 has the pinned hash, using `https://ethereum-rpc.publicnode.com`, the only endpoint used. - **Method:** I did not use `scan.mjs`. I pulled every collection `Transfer` log in the window (23 logs in 8 transactions). I then decoded each transaction's Seaport 1.5 and 1.6 `OrderFulfilled` events. A fill of the token must emit a `Transfer`, so this catches every qualifying fill. - **Result:** All 23 fills were single ERC-721 sales of the collection paid in ETH, so none were excluded. That gives 23 sales for 23 transfers. I ran no second scan. - **Recipe kind:** The brief says `"evidence": "panel"`, and the checker rejects any recipe other than `panel` for such a brief. The recipe is therefore `panel` with the RPC and the method as its source, even though the data is on chain. I put the full method in `notes`. The scratch script is `test/scratch/q.mjs` (not submitted). `artifacts/answer.json` is untracked, and git shows no other changes.
I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price is **12325908260869565 wei**. - **Sales counted:** 23 qualifying Seaport fills across the pinned blocks 26019452–26026608, totalling 283495890000000000 wei. The mean is rounded down. - **Method:** I pulled the collection's `Transfer` logs over the window, which gave 8 transactions. I read those receipts and decoded the `OrderFulfilled` events from both Seaport contracts using the request's definitions. That skips a full scan of every Seaport log; any Seaport sale of this collection must include a `Transfer` in the same transaction. - **Pin check:** the closing block hash matched on publicnode. I did not check it on a second operator's endpoint. - **Repeated fills:** I counted each `OrderFulfilled` event separately, including several in one transaction, and stated that in `definitions`. Several fills in one transaction carry identical prices (for example six at 0.011 ETH). If the deployer's rerun dedupes these, the answer would differ. - **Recipe:** the brief says `"evidence": "panel"`, so the recipe kind had to be `panel`. It can only name a source URL, not a rerunnable computation. It names `https://ethereum-rpc.publicnode.com`, and the exact steps are in `notes`. My script is in `test/scratch/s.mjs`, which isn't submitted.

`artifacts/answer.json` is written, and the check script prints `ok`. The average sale price of Human Resources over blocks 26019452 to 26026608 is **12325908260869565 wei**. That is the floor of 283,495,890,000,000,000 wei across 23 qualifying sales. - **Scan:** I pulled all 12,232 `OrderFulfilled` logs from both Seaport contracts over exactly the pinned blocks, after confirming chain id 1 and the pinned closing hash. I read them from `https://ethereum-rpc.publicnode.com` only and did not cross-check a second operator. - **Decoding:** I decoded each log against the Seaport ABI and kept fills with exactly one NFT item, an ERC-721 of the collection. Listing fills sum the consideration amounts, and bid fills use the offer amount. No fills were dropped as bundles or as paid in another token. - **Recipe kind:** The brief says `"evidence": "panel"`, and `check-answer.mjs` requires a `panel` recipe for that. The recipe therefore names the RPC source instead of a rerunnable log recipe. The catalogue has no recipe that decodes nested Seaport arrays anyway. - **Files:** My scan script is in `test/scratch/`, which is not submitted, and `git status` shows nothing tracked as changed.

The average sale price of Human Resources over blocks 26019452 to 26026608 is **12325908260869565 wei**. `check-answer.mjs` prints `ok` for `artifacts/answer.json`. - **Sales counted:** 23 qualifying sales totalling 283495890000000000 wei, rounded down after dividing. - **Scan:** 12,232 OrderFulfilled logs from both Seaport contracts over exactly the pinned blocks, read from `ethereum-rpc.publicnode.com`. I did not fall back to another endpoint (`notes` only says it would rotate on error). The chain id and the closing block hash matched the pin. - **Decoding:** `scan.mjs` can't decode the nested offer and consideration arrays. I wrote my own scanner in `test/scratch/s.mjs`, which applies the definitions from `oracle.json`. - **Recipe kind:** the brief says `evidence: "panel"`, and `check-answer.mjs` rejects any recipe other than `panel` for such a brief. The recipe is therefore `{kind: "panel", source: <URL>}`, with the endpoint and event topic in the source and the scan details in `notes`. The deployer can't rerun it as a chain recipe. - **Second endpoint:** I did not cross-check the closing hash on a second endpoint from a different operator, which the reference suggests. - **Fix during checking:** the check first failed because my `window` keys were in a different order from the brief's. I reordered them to match.
Answer: **12325908260869565** wei (23 qualifying Seaport fills, sum 283495890000000000 wei, floored mean). Checker: `ok` for `artifacts/answer.json`.
Wrote `artifacts/answer.json`: **12,325,908,260,869,565 wei**, averaged across 23 qualifying sales. Included definitions and RPC reproduction steps. The required checker printed `ok`.
`check-answer.mjs` prints `ok` (exit 0). Done. **Answer: 12325908260869565 wei** (avg), from **23** qualifying sales summing **283495890000000000 wei**. How it was computed: - **Pin confirmed three ways** — `scan.mjs --pin` on `rpc.flashbots.net/fast` (chainId 1, `pinned: true`), plus `eth_getBlockByNumber(0x18d2270)` on `ethereum-rpc.publicnode.com` and `rpc.mevblocker.io/fast`, both returning `0x84272223…fbf3f`. - **Discovery** — `scan.mjs` over the collection's `Transfer` topic across the pinned range: 23 ERC-721 transfers in 8 blocks, 8 transactions. Every qualifying Seaport fill moves the token, so this misses nothing. - **Decode** — `scan.mjs` can't read `OrderFulfilled`'s dynamic `SpentItem[]`/`ReceivedItem[]`, so a scratch script (`test/scratch/seaport-avg.mjs`, not submitted) pulled those 8 receipts and decoded the Seaport events with the same chunk-halving, endpoint rotation and log de-duplication. - **Result** — 23 `OrderFulfilled` events touch the collection, all Seaport 1.6, all single-ERC-721 listing fills paid entirely in native ETH, fees included. Nothing was excluded as a bundle, ERC-1155, or non-ETH payment; the 23 transfers map one-to-one onto the 23 sales. `283495890000000000 / 23` floors to `12325908260869565`, clearing the `min: 1` guard. Two judgment calls worth flagging, both stated under `definitions`: - The brief sets `"evidence": "panel"`, and `check-answer.mjs` refuses any chain recipe on such a brief — so `recipe` is `{ kind: "panel", source }` even though the question is on-chain. The `source` names the endpoint and the exact log query, and the figure itself was computed over the pinned blocks, not read off an indexer. - Each `OrderFulfilled` counts as one sale, including the six fills sharing block 26026555 and the seven sharing 26026565; the definitions fix a sale as the event, not the transaction. `artifacts/answer.json` is 4378 bytes and untracked (the path is gitignored) for the daemon to upload.

Created `artifacts/answer.json` with an average of **12,325,908,260,869,565 wei** across 23 qualifying sales, plus standalone RPC reproduction code. The required checker printed `ok`.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price of Human Resources over blocks 26019452 to 26026608 is **12325908260869565 wei**, about 0.01233 ETH. - **Sales counted:** 23 fills qualified, all listing fills paid in ETH or WETH, with no bids and none excluded. Their prices sum to 283495890000000000 wei, and the average is that sum divided by 23, rounded down. - **How I computed it:** The provided `scan.mjs` doesn't decode Seaport events, so I wrote my own scan in `test/scratch/hr.mjs`. It found the collection's 23 ERC-721 Transfer logs in the window, which fall in 8 blocks. For those blocks it pulled Seaport 1.5 and 1.6 `OrderFulfilled` logs and applied your definitions. - **Chain pin:** Chain id 1 and the closing block hash `0x84272223…bf3f` matched the brief. I used `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`. - **Recipe:** The brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe there, so the recipe is `{kind: "panel", source: <URL>}`. The source is a public RPC URL followed by a description of the log query and filters, and the full method is in `notes`. - **File status:** The file is untracked and not committed. `test/scratch/` holds my scan and writer scripts and isn't submitted. I only scanned Seaport logs in the blocks where the collection had a Transfer. Every Seaport sale of the collection emits a Transfer, so this shouldn't miss any. Each of those 23 Transfers was itself one of the qualifying sales.
The expired monitor doesn't change anything. It was watching the first scan attempt, which crashed on the bad topic. The rerun finished, and `artifacts/answer.json` is written and passes `check-answer.mjs`. The answer is 12325908260869565 wei, the floor of 283495890000000000 wei over 23 sales. I don't need to re-arm the monitor or do any more work.
Created [artifacts/answer.json](artifacts/answer.json) with the average **12,325,908,260,869,565 wei** across 23 qualifying sales and dependency-free reproduction code. Required checker result: `ok`.
The average sale price was **12325908260869565 wei** (about 0.01233 ETH). It's written to `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. - **Scan:** I pulled every `OrderFulfilled` log from both Seaport contracts (1.5 and 1.6) over exactly blocks 26019452 to 26026608, from `https://ethereum-rpc.publicnode.com`. That was 12,232 logs. I ran the scan twice and got the same totals both times. - **Chain and closing block:** the chain id was 1, and the closing block hash matched the pinned one on that endpoint and on `https://rpc.flashbots.net/fast`. - **Sales:** 23 fills qualified under the brief's definitions. All were listing fills paid entirely in ETH/WETH. There were no bid fills, and no fill of this collection was left out for paying in another token. - **Result:** the prices, fees included, add up to 283495890000000000 wei. Divided by 23 and rounded down, that gives the answer. - **Recipe:** the brief marks this as a panel-evidence question, so the checker only accepts the `panel` recipe kind. Its `source` is the exact log query above: both Seaport addresses, the `OrderFulfilled` topic, and the pinned block range. - **Helper script:** the provided `scan.mjs` can't decode Seaport's item lists, so I decoded the logs with a small script in `test/scratch/`. It is not submitted, so `notes` describes what it did. - **Definitions:** I wrote how I read "sale", "price" and "average" under `definitions`. One choice there: each qualifying `OrderFulfilled` event counts as one sale.

Created `artifacts/answer.json` with average **12325908260869565 wei**, computed from 23 qualifying sales, and a self-contained reproduction script. Required validator printed `ok`.
Done. `artifacts/answer.json` is written and passes `check-answer.mjs`. Summary: scanned OrderFulfilled logs from both Seaport 1.5 and 1.6 over blocks 26019452–26026608 (chain id 1, closing hash confirmed on two independent public RPCs after publicnode.com refused the range with an archive-node error and I fell back to rpc.flashbots.net/fast). Of 12,232 total logs, 23 qualified as single-ERC-721 fills of the Human Resources collection (0x88a409734e5997f1fda972cb1bb577e5b88c19da) paid entirely in ETH/WETH — all listing fills, no bid fills. Sum = 283,495,890,000,000,000 wei over 23 sales → average = **12,325,908,260,869,565 wei** (truncated). Since `oracle.json` marks `"evidence": "panel"`, the reference requires the recipe be `{kind: "panel", source}` even though the fact was computed live from chain logs — I recorded the RPC endpoint and topic/contract details as the source, with the full methodology in `notes`.
