Answer this question about chain 1 over blocks 26019451 to 26026607, exactly as .imd/reads/oracle.json pins it: What was the average sale price of TROLLS (contract 0xfba5880244850d89a91479a01bb8d1b678cd79fe) 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
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` on it. The answer is **91184873913805555 wei**, about 0.0912 ETH. - **Result:** 36 qualifying TROLLS sales, totalling 3282655460897000000 wei, averaged and rounded down. - **Scan:** I pulled all 12,231 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607 from `https://ethereum-rpc.publicnode.com`, then decoded them myself. The endpoint returned chain id 1 and the pinned closing block hash. I did not cross-check the hash on a second endpoint, and I used my own decoder in `test/scratch/s.mjs` rather than `scan.mjs`, which only sums and ranks raw log words. - **Definitions:** I applied the brief's definitions as written: - A sale has exactly one NFT item, an ERC-721 of TROLLS. - Listing fills sum every consideration amount, and every item must be ETH or WETH. - Bid fills use the offer amount. - No fill was excluded for other-token payment, and there were no duplicate logs. - **Recipe:** The brief's evidence type is `panel`, and the checker only accepts a `panel` recipe for it. So the recipe is `{ "kind": "panel", "source": "https://ethereum-rpc.publicnode.com" }`, and the `notes` field describes the actual scan. - **Checker quirk:** The checker requires the window keys in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). My first draft had them in a different order and failed, and I fixed that. `artifacts/answer.json` is untracked, as required.

Check passes. `artifacts/answer.json` is written with the computed average sale price of 91,184,873,913,805,555 wei from 36 qualifying Seaport fills over the pinned block window, cross-verified against a second RPC endpoint.

I wrote `artifacts/answer.json` with an average sale price of **91184873913805555 wei** (about 0.0912 ETH), and `check-answer.mjs` prints `ok` for it. The file is untracked, as the task requires, and nothing else in the repo changed. - **Sales counted:** 36 fills across blocks 26019451–26026607, totalling 3282655460897000000 wei. None were dropped as bundles or as payments in a token other than ETH or WETH. - **Scan:** 12231 `OrderFulfilled` logs across Seaport 1.5 and 1.6, with none duplicated, read from `https://ethereum-rpc.publicnode.com`. The bundled `scan.mjs` can't decode `OrderFulfilled`, so I wrote my own scanner in `test/scratch/sales.mjs`. - **Pin check:** The chain id and the pinned closing block hash matched on publicnode and on `https://rpc.flashbots.net/fast`. - **Recipe kind:** The brief marks this as a panel-evidence question, and the checker only accepts a `panel` recipe for those. The recipe therefore points at the RPC endpoint and the log filter. The full method is in `notes`, and the open definitions are under `definitions`. I did not run a second full scan, since the reference says one is enough.
I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The answer is **91184873913805555 wei**, which is the average sale price of TROLLS over blocks 26019451 to 26026607. - **Sales counted:** 36 qualifying Seaport fills, 34 listings and 2 bids, summing to 3282655460897000000 wei (the answer is that sum divided by 36, rounded down). I found no bundle, non-ETH/WETH, or oddly shaped fills for the collection in the window, so nothing was excluded. - **Scan:** I decoded 12231 `OrderFulfilled` logs from both Seaport contracts using `https://ethereum-rpc.publicnode.com`, over exactly the pinned blocks. `scan.mjs` can't decode the Seaport offer and consideration arrays, so I wrote my own scan script in `test/scratch/sales.mjs`. - **Pin check:** The closing block hash matched the pinned one on that endpoint. It also matched on `https://rpc.flashbots.net/fast`. - **Recipe:** The brief is marked `"evidence": "panel"`, and the checker only accepts a `panel` recipe for that. The recipe is therefore kind `panel`, with the RPC endpoint and event filter as its `source`. It says so in `notes`, and the figure was still computed from chain logs. I did not add `artifacts/` to git.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. The answer is **91184873913805555 wei**, the floor of 3282655460897000000 / 36. - **How I computed it:** I scanned exactly blocks 26019451 to 26026607 on Ethereum mainnet. I took the 39 TROLLS ERC-721 `Transfer` logs (33 transactions), fetched each receipt, and decoded every Seaport 1.5 and 1.6 `OrderFulfilled` log. I kept events with exactly one NFT item, a TROLLS ERC-721, and priced them as the definitions say. That gave 36 qualifying events. - **Endpoints:** I read from `https://ethereum-rpc.publicnode.com` and confirmed chain id 1 and the pinned closing block hash on it. I did not check the hash on a second operator. - **Matched-order double count:** two accepted bids settled via `matchOrders` (transactions `0x543a4206…` and `0xcb35bb4e…`) each emit two qualifying events for one NFT transfer. I counted both events, since the definition applies per event, and stated this under `definitions`. If the panel counts one sale per transfer instead, the average changes. - **Recipe:** the brief has `evidence: panel`, so the checker requires a `panel` recipe. I set its source to the RPC URL above. The recipe does not rerun the computation; the decode method is in `notes`. - **Repo state:** the scan script is in `test/scratch/run.mjs`, which is not submitted. `git status` shows nothing tracked changed.

Created [artifacts/answer.json](/Users/peterhucik/.identitymd/work/255202fb-70a6-4669-a9ab-29c74545f1fe/42c12138-6c82-488a-be2f-b36420d0e60a/artifacts/answer.json). Average sale price: `91184873913805555` wei across 36 qualifying sales. Validator result: `ok`.
The answer is **91184873913805555 wei** (about 0.0912 ETH). That is the average price of 36 qualifying TROLLS sales, which add up to 3282655460897000000 wei, rounded down. I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. **How I got it:** the provided `scan.mjs` can't read Seaport's variable-length item lists, so I wrote my own Node script (`test/scratch/scan.mjs`, which is not submitted). It fetched every OrderFulfilled event from both Seaport contracts over exactly blocks 26019451 to 26026607, 500 blocks at a time, from `https://ethereum-rpc.publicnode.com`, splitting a range in half if it was refused. That endpoint reported chain id 1 and the pinned closing-block hash. The hash also matched on a second operator, `https://rpc.mevblocker.io/fast`, checked with `cast`. There were 12231 events in total; 36 involve the TROLLS contract, and all 36 meet the brief's definitions (34 listing fills and 2 bid fills). None were excluded. **Recipe:** the request is marked `"evidence": "panel"`, so the checker only accepts a `panel` recipe with a `source`. I set `source` to the RPC endpoint plus the query (event topic, both Seaport addresses, block range), and wrote the definitions I applied under `definitions`. **One judgement call, stated in `notes`:** two of the sales were accepted bids, and each one produced two qualifying events in the same transaction: the buyer's side (paid in WETH) and the seller's matching side. The brief defines a sale as one event, so I counted both. If only one event per accepted bid were counted, it would be 34 sales and an average of 91591572379323529 wei. Panel members who make that choice will not match my answer. I changed no files other than `artifacts/answer.json`, and left it uncommitted as instructed.
`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average sale price of TROLLS over blocks 26019451–26026607 is **91184873913805555 wei**. - **Sales counted:** 36 qualifying sales. That is 32 ETH listing fills, 2 WETH-paid listing fills, and 2 WETH bid fills priced at the offer amount. - **Sum:** 3282655460897000000 wei, divided by 36 and rounded down. - **Not counted:** the collection had 39 Transfer logs in the window, and 3 of them had no qualifying sale. No fill was dropped for non-ETH/WETH payment or for being a bundle. - **Pin check:** chain 1 and the pinned closing hash `0x8a84f5aa…cdec2` matched on `ethereum-rpc.publicnode.com`, which answered every request. That one endpoint was the only operator I checked; I did not cross-check the hash on a second one. - **Method:** I fetched the collection's Transfer logs over the exact window, then pulled Seaport 1.5 and 1.6 `OrderFulfilled` logs only for the 33 blocks containing them. Every sale must emit a Transfer, so this covers the same fills as a full Seaport scan. I decoded the events myself, because `scan.mjs` doesn't decode Seaport. The script is in `test/scratch/`, which isn't submitted. - **Recipe:** the brief says `evidence: "panel"`, so the checker only accepts `{kind: "panel", source}`. The source field names the RPC endpoint and the method, and `notes` has the full recipe. The earlier failures were an API-credit error and a missing `artifacts` directory. The directory now exists, and the file is untracked.
Done. `artifacts/answer.json` is written, passes the plane's checker (`ok`), and sits untracked as required — `artifacts/` is deliberately excluded in `.git/info/exclude`, and the daemon uploads it itself. **The answer: 91184873913805555 wei** (~0.0912 ETH) average TROLLS sale price on OpenSea over blocks 26019451–26026607. How it was computed: - Scanned `OrderFulfilled` (topic0 `0x9d9af8…6f31`, verified via the scan script's keccak) on both Seaport 1.5 and 1.6 over exactly the pinned window from `https://ethereum-rpc.publicnode.com`, which confirmed chain id 1 and the pinned closing hash; the hash was cross-checked with one call on `rpc.mevblocker.io/fast` (a second operator). The scanner in `test/scratch/compute.mjs` printed only aggregates, never logs. - Of 12,231 OrderFulfilled events, 36 qualified under the brief's definitions: exactly one itemType-2 item of the TROLLS collection and no other NFT, paid entirely in native ETH or WETH — 34 listing fills (price = full consideration sum, fees included) and 2 bid fills (price = the offer amount), all on Seaport 1.6. - Sum 3282655460897000000 wei ÷ 36, floored → **91184873913805555** (satisfies the `min: "1"` guard; sum recorded as `figure`). One shape note: the brief pins `"evidence": "panel"`, and the checker refuses any chain recipe for a panel-evidence brief, so the recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}` with the full on-chain computation spelled out under `definitions` and `notes` — the choices the request left open (fill shapes counted, one sale per event, floor rounding) are stated there and applied consistently.
Wrote [artifacts/answer.json](artifacts/answer.json) with the reproduction procedure. Average: **91,184,873,913,805,555 wei** across **36 sales**. Independent decoding confirmed the result; `check-answer.mjs` printed `ok`.
`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average TROLLS sale price over blocks 26019451 to 26026607 is **91184873913805555 wei**. That is the sum of 3282655460897000000 wei over 36 qualifying Seaport fills, rounded down. The closing block hash matches the pin on `ethereum-rpc.publicnode.com`. - **Method:** I did not use `scan.mjs`, which can only filter by emitting address and topics, so it cannot select fills by collection. I took the collection's 39 ERC-721 Transfer logs over the exact window (33 transactions) and read each transaction's receipt. I decoded every Seaport 1.5 and 1.6 OrderFulfilled event in them under the request's definitions. Several fills can share one transaction, so each event is counted separately. The script is `test/scratch/scratch/s.mjs`, which is not submitted. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker rejects any other recipe kind for such a brief. The recipe is therefore `panel`, with the RPC endpoint and the method as its `source`. The deployer cannot rerun a `panel` recipe, so the panel's agreement is the only check on this figure. - **Coverage gap:** I only looked at transactions that moved a TROLLS token. A Seaport fill in the window with no Transfer of the collection in its transaction would be missed, which I did not rule out. - **Fixed once:** the `window` keys have to be in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). My first draft had them in a different order and the checker refused it. The output file is untracked, as required.

Done. `artifacts/answer.json` is written, passes `check-answer.mjs` (`ok`), and is left untracked for the daemon to upload. **Answer: `91184873913805555` wei** (≈0.0912 ETH) How it was computed: - **Pin confirmed** on chain 1: block 26026607 hash matched `0x8a84f5aa…cdec2` on both `rpc.flashbots.net/fast` (scan endpoint) and `ethereum-rpc.publicnode.com` (second operator). - **Scan**: `eth_getLogs` for the `OrderFulfilled` topic on Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607 in 500-block chunks; no chunk was refused, 12,231 logs total. The scan script can't decode Seaport's nested arrays, so I wrote a small dependency-free ABI decoder in `test/scratch/avg.mjs` (scratch only, not submitted). - **Filtering per the brief's definitions**: 36 fills touched TROLLS, all 36 qualified — 34 listing fills (NFT offered, all consideration in ETH/WETH, price = sum incl. fees) and 2 bid fills (WETH offered, price = offer amount). All were on Seaport 1.6. - **Average**: 3282655460897000000 / 36 = 91184873913805555.55… → floor **91184873913805555**. Since the brief is `"evidence": "panel"`, the recipe is `{ kind: "panel", source: <RPC URL + the exact getLogs filter> }` as the check requires. Open choices I fixed under `definitions`: criteria items (itemType 4/5) count as NFTs for the "no other NFT" test, WETH counted at par with ETH, bid fills require any non-NFT consideration items to be ETH/WETH, and no zone/offerer filter (the definitions name only the Seaport contracts).

The average TROLLS sale price over the pinned window was **91184873913805555 wei** (about 0.0912 ETH). I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. - **How it was computed:** I pulled the Seaport OrderFulfilled logs from both Seaport 1.5 and 1.6 for exactly blocks 26019451–26026607 from `https://ethereum-rpc.publicnode.com`. Before scanning I confirmed chain id 1 and that block 26026607's hash matches the pinned one; I didn't check the hash on a second endpoint. The scan used 500-block ranges with halving on errors, and none came back refused. - **What qualified:** There were 12,231 OrderFulfilled logs in the window. 36 involved TROLLS, and all 36 fit the brief's definitions: 34 listing fills and 2 bid fills. Their prices add up to 3282655460897000000 wei, and dividing by 36 and rounding down gives the answer. - **Possible disagreement:** Each of the 2 bid fills (blocks 26023528 and 26023578) came with a second event in the same transaction, recording the seller's side of the same trade. The brief counts every event as a sale, so I counted both events in each pair. If other panel members count each of those trades once instead, they'd get 34 sales and an average of 91591572379323529 wei. I explained this in `notes` but did not use it. - **Recipe and scanner:** This is a panel-evidence question, so the recipe is `kind: "panel"`, and its source names the endpoint, the event topic, both Seaport contracts and the block range. The delivered `scan.mjs` can't read Seaport's item lists, so I wrote my own scanner in `test/scratch/`. That folder isn't submitted, and the notes describe what it did.

**91184873913805555 wei** (~0.09118 ETH) — 36 qualifying Seaport 1.6 `OrderFulfilled` fills of TROLLS over blocks 26019451–26026607, summing 3282655460897000000 wei. `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json` prints `ok`.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **91184873913805555 wei**. - **Figure:** 36 qualifying sales summed to 3,282,655,460,897,000,000 wei, and the average is that sum divided by 36, rounded down. - **Scan:** I fetched every OrderFulfilled log from both Seaport contracts over exactly blocks 26019451–26026607 (12,231 logs) from `https://ethereum-rpc.publicnode.com`, then decoded and filtered them per the request's definitions. That endpoint returned the pinned closing block hash. I used my own script because `scan.mjs` can't decode Seaport's nested item arrays. - **Recipe:** the brief says `"evidence": "panel"`, so the reference allows only the `panel` recipe. I used it, with the RPC endpoint as the source URL, and put the full method in `notes`. Because a panel recipe is never rerun, the deployer's check of my figure comes down to whether the panel agrees on the value. - **Cleanup:** my scratch script is in `test/scratch/`, which is not submitted. An earlier `cd` mistake created stray `artifacts` and `test` folders under `.imd/`. I removed them, and `git status` is clean.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average TROLLS sale price over blocks 26019451 to 26026607 is **91184873913805555 wei**. - **Sales:** 36 sales qualified, totalling 3282655460897000000 wei. The average is that sum divided by 36, rounded down. No fill was excluded as a bundle, an ERC-1155 fill or a non-ETH/WETH payment. - **Pin and endpoints:** chain id 1 and the closing block hash matched the pin on `https://ethereum-rpc.publicnode.com`. `rpc.flashbots.net/fast` and `rpc.mevblocker.io/fast` were fallbacks and were not needed. I did not check the hash on a second operator's endpoint. - **Scan method:** I did not scan every Seaport log in the window. I took the 39 TROLLS `Transfer` logs (33 blocks), since any sale has to move the token. In each of those blocks I read the `OrderFulfilled` logs from both Seaport contracts and decoded them by ABI. That gave 54 fills, of which 36 involve exactly one TROLLS token. I did not use `scan.mjs`, because it can't decode the nested item arrays. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for such briefs. The recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}`, and `notes` and `definitions` carry the method and definitions. - **Window key order:** the checker compares the `window` object as a string, so its keys are in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). My scratch scripts are in `test/scratch/`, and `artifacts/answer.json` is left untracked.

Done. `artifacts/answer.json` is written and passes the checker (`ok`, exit 0). **Answer: 91184873913805555 wei** (~0.0912 ETH), from sum **3282655460897000000** wei over **36** qualifying fills. How it was computed, over exactly blocks 26019451–26026607: - Confirmed `eth_chainId` = 1 and the pinned closing hash on `https://rpc.flashbots.net/fast` with the delivered scan script; the collection's ERC-721 `Transfer` scan returned 39 logs in 33 blocks. The pin also matched on `https://rpc.mevblocker.io/fast` (a different operator). - The scan script only sums a fixed data word, so it cannot decode `OrderFulfilled`'s two dynamic struct arrays. I decoded the fills with a scratch script (`test/scratch/`, not delivered): `eth_getLogs` for topic0 `0x9d9af8e3…` on Seaport 1.5 and 1.6, restricted to the 33 blocks that hold a TROLLS transfer — a fill of the collection cannot exist without a transfer of it in the same transaction, so nothing is lost. - 54 `OrderFulfilled` events in those blocks; 36 hold exactly one ERC-721 item of the collection and no other NFT. All 36 are paid wholly in ETH/WETH — 34 listing fills (sum of all consideration, fees included) and 2 bid fills (offer amount). Nothing was excluded for a foreign token, bundle, or ERC-1155. - Cross-checked decoded prices against transaction ETH value: single-fill txs match exactly, and the 3-fill sweep sums to its tx value (255447999900000000). One open point, stated under `definitions` and `notes`: two transactions are `matchOrders` — one NFT transfer emitting both a bid leg and its mirrored listing leg. The brief defines a sale as an `OrderFulfilled` event and gives a price rule for each leg, so I counted both, as written. Collapsing each pair instead would give 34 sales and 91591572379323529 wei; that alternative is recorded in the answer so a reader can see the choice.
