I wrote `artifacts/answer.json` with an average VLNS sale price of **44781259259259259 wei**, and `check-answer.mjs` prints `ok` for it. - **Sales counted:** 27 qualifying sales totalling 1209094000000000000 wei, averaged with integer division. - **Scan:** I fetched all 12,232 Seaport 1.5 and 1.6 `OrderFulfilled` logs over blocks 26019452 to 26026608, then decoded them myself and filtered by the request's definitions. - **Endpoint:** the scan ran on `https://ethereum-rpc.publicnode.com`, with `rpc.flashbots.net/fast` and `rpc.mevblocker.io/fast` as fallbacks on errors. I confirmed chain id 1 and that block 26026608's hash matches the pin on the endpoint I queried. I did not check the hash on a second operator. - **Recipe kind:** the request says `"evidence": "panel"`, so the recipe is `panel` with the RPC URL as its source. That is only a pointer to the source. `notes` and `definitions` describe how to reproduce the figure. - **Scan script:** the provided `scan.mjs` can't decode `OrderFulfilled`'s nested items. The decoder I used is `test/scratch/s.mjs`, which is not submitted. The check initially failed because the `window` keys were in the wrong order, so I reordered them to match the request.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average VLNS sale price over blocks 26019452 to 26026608 is **44781259259259259 wei**. - **Sales:** 27 sales qualified under the brief's definitions, totalling 1209094000000000000 wei; the average is that total divided by 27, rounded down. - **Recipe kind:** The brief says `evidence: "panel"`, so the recipe has to be `kind: "panel"` with a source URL. The URL I gave is the RPC endpoint plus the Seaport contracts, event topic and block range. - **Custom script:** I used my own Node script at `test/scratch/run.mjs` rather than `scan.mjs`, because `scan.mjs` can't decode Seaport's nested offer and consideration items. - **Method:** The script pulled the collection's ERC-721 Transfer logs over the window (481 logs across 356 blocks). It then read Seaport `OrderFulfilled` logs from both Seaport contracts for only those blocks (726 logs), decoded them, and applied the sale and price definitions. - **Checks:** The script confirmed chain id 1 and the pinned closing block hash on `https://ethereum-rpc.publicnode.com`, the only endpoint used. I did not cross-check on a second endpoint or rescan. - **Git:** The artifact is untracked, as required.

Created `artifacts/answer.json` with the answer **44,781,259,259,259,259 wei**, computed from 27 qualifying sales, plus definitions and reproduction code. The required checker printed `ok`.

Average: **44,781,259,259,259,259 wei** across 27 qualifying sales. Created `artifacts/answer.json` with definitions and reproduction details. Required checker printed `ok`.

I wrote `artifacts/answer.json`. The average VLNS sale price over blocks 26019452 to 26026608 is **44781259259259259 wei**, and `check-answer.mjs` prints `ok` for it. - **Sales counted:** 27 qualifying sales, 26 listing fills and 1 bid fill, summing to 1209094000000000000 wei. No otherwise-qualifying fill was dropped for being paid in another token. - **How I got it:** I fetched all 12232 OrderFulfilled logs from both Seaport contracts over exactly the pinned blocks from `https://ethereum-rpc.publicnode.com`, then decoded and filtered them as the brief's definitions say. - **Pin check:** the closing block hash matched the pin on publicnode and on `https://rpc.flashbots.net/fast`. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for that. So the recipe is `panel`, with the RPC endpoint and event topic as its source. The catalogue's `log-sum` could not decode the nested item arrays anyway, so `notes` explains the computation. - **Definitions:** the answer's `definitions` field states the sale, price and average rules and the log deduplication I used. I did not use `scan.mjs`, since it can't decode the nested item arrays. My own script is in `test/scratch/sales.mjs`, which isn't submitted.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. The average sale price is **44781259259259259 wei**. That is 1209094000000000000 wei summed over 27 qualifying sales, rounded down. I scanned 12,232 Seaport `OrderFulfilled` events over blocks 26019452 to 26026608 and applied the request's definitions. The closing block hash matched the pin. - **Endpoint:** I used only `https://ethereum-rpc.publicnode.com`, one operator, and did not check the hash on a second endpoint. - **Recipe kind:** the recipe catalogue has no recipe that can decode `OrderFulfilled`, which carries nested struct arrays. I used `panel`, since the brief's evidence is `panel`, with the endpoint as the source. The deployer can't rerun `panel` recipes, so it has nothing to rerun this answer against; that is noted in `notes`. - **Reproducing it:** the decoding script is in `test/scratch/s.mjs`, which is not submitted.

Created `artifacts/answer.json` with **44781259259259259 wei**, averaged over 27 qualifying sales. The included reproduction code returned the same result. The required validator printed `ok`.

**Answer: 44781259259259259 wei** (≈0.04478 ETH), written to `artifacts/answer.json` — `check-answer.mjs` prints `ok`. How it was computed, over exactly blocks 26019452–26026608: - **Pin confirmed twice.** `scan.mjs` on `rpc.flashbots.net/fast` returned chainId 1, `pinned: true`, and 481 VLNS ERC-721 `Transfer` logs across 356 blocks; `ethereum-rpc.publicnode.com` (different operator) returned the same closing hash and the same 481 logs. - **Seaport decode.** `scan.mjs` only prints sums, and OrderFulfilled prices sit in dynamic struct arrays, so a local script fetched `OrderFulfilled` logs (topic0 `0x9d9af8e3…`) from Seaport 1.5 and 1.6 over the 356 blocks that moved a collection token — a fill of a collection ERC-721 must move it in the same block, so nothing is lost — and ABI-decoded them. 726 events in those blocks, 27 touch the collection, **all 27 qualify**: no bundle, no ERC-1155, no non-ETH/WETH payment was excluded (all exclusion counters zero). All 27 came from Seaport 1.6. - **Figures.** Sum 1209094000000000000 wei over 27 sales → 44781259259259259 after rounding down. 26 listing fills, 1 bid fill, prices 0.010494–0.15 ETH, 26 distinct token ids. Above the guard `min: 1`. The one open judgement, stated under `definitions` and in `notes`: tx `0x88297a84…` is a matched bid/listing pair where Seaport emits OrderFulfilled for each side of one trade (0.0106 gross / 0.010494 to the seller). The brief defines a sale as *the event*, so both sides count; counting that trade once instead would give 26 sales and 46100000000000000 wei — recorded so a reader can see which reading produced which number. Because the brief carries `"evidence": "panel"`, the recipe is the `panel` kind (the checker refuses a chain recipe here); its `source` names the endpoint, event, both Seaport contracts and the exact blocks, so the computation is reproducible from public RPC data alone. `artifacts/answer.json` is untracked (`.git/info/exclude` ignores `artifacts/`).

`artifacts/answer.json` is written and passes `check-answer.mjs`. **Result:** average VLNS sale price = **44781259259259259 wei** (≈0.0448 ETH), from 27 qualifying Seaport fills (sum 1209094000000000000 wei) over blocks 26019452–26026608. Method: scanned both Seaport 1.5 and 1.6 contracts for `OrderFulfilled` over the exact pinned range via `https://rpc.flashbots.net/fast` (chain id and the pinned closing hash cross-checked on `https://rpc.mevblocker.io/fast`), hand-decoded each log's `offer[]`/`consideration[]` structs (validated against two sample sales), and applied the request's definitions (exactly one ERC-721 VLNS item, no other NFT, all consideration/offer legs in ETH or WETH). Since this event's per-item filtering can't be expressed as a single-field `log-sum`, and the brief is marked `evidence: panel`, the recipe is filed as `panel` with the on-chain method stated as `source` (the only kind `check-answer.mjs` accepts for a panel-evidence brief).

Answer: **44781259259259259 wei** (27 qualifying Seaport 1.6 OrderFulfilled fills, sum 1209094000000000000 wei, floored mean ≈ 0.0448 ETH). `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` prints `ok`.

I've read the brief and the scripts. This is a chain-1 question pinned to blocks 26019452–26026608: average VLNS sale price from Seaport `OrderFulfilled` events. The `OrderFulfilled` event has nested item arrays, so the provided scan script can't decode it — I'll write a scratch scanner that fetches the logs, decodes offer/consideration, and applies the definitions. First, let me verify the event topic and check RPC connectivity.Topic confirmed: `0x9d9af8e38d66c62e2c12f0225249fd9d721c54b83f48d9352c97c6cacdcb6f31`. Now I'll write a scratch scanner that fetches and decodes the `OrderFulfilled` logs per the brief's definitions.Pin confirmed, scan completed: 12,232 `OrderFulfilled` logs, 27 qualifying VLNS sales. Before writing the answer, let me sanity-check the distribution (any zero-price fills, listing vs bid split) since edge cases affect the mean.Identical result on a second operator (pin confirmed both times): 12,232 `OrderFulfilled` logs, 27 qualifying sales — 26 listings, 1 bid, no zero-price fills. Sum = 1,209,094,000,000,000,000 wei; floored mean = 44,781,259,259,259,259 wei. Writing the answer.The checker passes. Quick verification that nothing outside `artifacts/answer.json` and `test/scratch/` was touched.Done. `artifacts/answer.json` passes the plane's checker (`ok`). **Answer: `44781259259259259` wei** (~0.0448 ETH) — the floored mean VLNS sale price over blocks 26019452–26026608. How it was computed: - Fetched all `OrderFulfilled` logs (topic `0x9d9af8e3…dcb6f31`) from Seaport 1.5 and 1.6 over exactly the pinned window — 12,232 logs total, pinned closing hash verified. - Decoded offer/consideration item arrays from event data and applied the brief's definitions: exactly one itemType-2 item of `0x357b…f626`, no other NFTs, single-item offer; listing fills priced as the sum of ETH/WETH consideration (fees included, all-ETH/WETH required), bid fills priced as the offer amount. - Result: 27 qualifying sales (26 listings, 1 bid), sum 1,209,094,000,000,000,000 wei, floored mean 44,781,259,259,259,259 wei. - Reproduced identically on a second endpoint (`ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`); both confirmed `eth_chainId=1` and the pinned block hash. Since the brief declares `"evidence": "panel"`, the recipe is `{kind: "panel", source}` naming the RPC the fact was read from — the only recipe kind the checker accepts for this brief.

Created `artifacts/answer.json`: **44,781,259,259,259,259 wei** averaged across **27 sales**. The included reproduction script returned the same result. Required validator printed `ok`.

`check-answer.mjs` prints `ok`. Done. **Answer: 44781259259259259 wei** (≈0.0448 ETH), written to `artifacts/answer.json` (untracked, 5675 bytes). How it was computed: - Scanned the pinned window 26019452–26026608 for topic0 `0x9d9af8e3…` (Seaport `OrderFulfilled`) on Seaport 1.5 and 1.6: **12,232 events**, closing hash matching the pin. - ABI-decoded each event's `offer`/`consideration`; **27** held exactly one ERC-721 item of `0x357b…f626` and no other NFT, all on Seaport 1.6 — 26 listing fills (consideration summed, fees and royalties included, all items ETH or WETH) and 1 bid fill (offer amount). Nothing was skipped for a foreign token, a bundle, or an ERC-1155. - Sum **1209094000000000000 wei** over 27 sales → floor mean **44781259259259259** (remainder 7 wei discarded). Min 0.010494 ETH, max 0.15 ETH. Checks run: `scan.mjs` couldn't reach the figure itself (the collection and amounts live in dynamic arrays, not a summable word), so the scan used a same-shaped scanner in `test/scratch/` with a Seaport decoder — same chunking, halving, dedup, and totals-only output. Flashbots answered 429 through the backoff and was dropped; the scan ran whole on `ethereum-rpc.publicnode.com` and again whole on `one.valve.city` (different operator) with identical log count, sale count and sum. For the single sale that was alone in its transaction and paid in native ETH, the transaction value equals the decoded price exactly. One thing worth flagging: the brief sets `"evidence": "panel"`, which the plane's own check forces to a `panel` recipe even though the question is a chain computation — so `recipe.source` carries the endpoint plus the exact `eth_getLogs` filter, and the decoding rules the request left open (per-event counting, no zone filter, WETH at par with ETH, floored mean) are all stated under `definitions` so another member can land on the same number.

Done. The answer is **44781259259259259 wei** (~0.0448 ETH) — the floor average of 27 qualifying VLNS sales. What I did: - **Scanned the chain directly.** The generic scan script can't decode Seaport's dynamic offer/consideration arrays, so I wrote a decoder in `test/scratch/vlns-scan.mjs` that fetches every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly blocks 26019452–26026608 via `https://ethereum-rpc.publicnode.com`, confirms `eth_chainId` and the pinned closing hash (also cross-checked on `https://rpc.flashbots.net/fast`, a second operator), and applies the brief's definitions in-process, printing only totals. - **Result:** 12,232 `OrderFulfilled` logs in the window; 27 qualified as sales of exactly one VLNS ERC-721 paid entirely in ETH/WETH (all on Seaport 1.6); total volume 1,209,094,000,000,000,000 wei; floor(sum/27) = 44,781,259,259,259,259 wei. This satisfies the `min: 1` guard. - **Wrote `artifacts/answer.json`** with the request id, chain, and window copied byte-for-byte from the brief (the checker compares the window with `JSON.stringify`, so key order matters), a `panel` recipe naming the RPC endpoint as the source (the brief is panel-evidence, so that is the only recipe kind the plane accepts), the total volume as `figure`, and `definitions` covering the choices the request left open: each event counts separately (including matchOrders pairs), "NFT" means any itemType 2 or 3 item, how listing vs. bid fills are priced, and WETH/ETH wei parity. - **`check-answer.mjs` prints `ok`**, and both `artifacts/` and `test/scratch/` are untracked, as required — the daemon uploads the answer itself.

Check passes. `artifacts/answer.json` is written with the computed answer of 44781259259259259 wei (≈0.0448 ETH), derived from 27 qualifying VLNS Seaport sales over the pinned block window, with a `panel`-kind recipe (matching the brief's `evidence: "panel"`) naming the exact RPC source and method.

Created [artifacts/answer.json](artifacts/answer.json) with the answer **44,781,259,259,259,259 wei**, based on 27 qualifying sales, plus definitions and reproduction code. The required checker printed `ok`.

`ok`, exit 0. Done. **Answer: 44781259259259259 wei** (≈0.0448 ETH) average VLNS sale price over blocks 26019452–26026608. How it was computed: - Confirmed `eth_chainId` = 1 and that block 26026608 hashes to the pinned `0x84272223…fbf3f`, on two independent operators. - Pulled every Seaport 1.5 + 1.6 `OrderFulfilled` log over exactly the pinned range from `ethereum-rpc.publicnode.com` (200-block chunks, no refusal/halving): **12232 logs**. The same filter on `eth-mainnet.public.blastapi.io` returned the same 12232 — so no silent truncation. - Decoded each log's `SpentItem[] offer` / `ReceivedItem[] consideration` and applied the brief's definitions: exactly one itemType-2 item of `0x357b9d3a…f626` and no other NFT; listing fills priced as the full consideration sum (fees included, ETH/WETH only), bid fills priced as the offer amount. - **27 qualifying sales** (26 listing fills, 1 bid fill); none dropped as bundle, ERC-1155, multi-item offer, or non-ETH/WETH payment. Sum 1209094000000000000 wei; floor(sum/27) = 44781259259259259. Clears the `min: 1` guard. One thing worth flagging: the brief sets `"evidence": "panel"`, and `check-answer.mjs` refuses any chain recipe on such a brief, so the recipe is `{kind: "panel", source}` naming the RPC + exact log filter. That is also the only honest fit — a Seaport fill price is a filtered sum over two dynamic item arrays in the log data, which `log-sum` cannot express with a single `sumArg`. The full decode procedure is spelled out in `notes` and `definitions` so another member or the deployer can reproduce it from public RPC data alone. `artifacts/answer.json` is written and untracked (the path is gitignored); scratch scanner lives in `test/scratch/avg.mjs`.

Done. `artifacts/answer.json` is written and the checker prints `ok`. **Answer: 44781259259259259 wei** (≈0.04478 ETH), from 27 qualifying Seaport fills totalling 1209094000000000000 wei. How it was computed, over exactly blocks 26019452–26026608: - Pin confirmed first: `eth_chainId` = 0x1 and block 26026608 = `0x84272223…837fbf3f` on four independent operators (flashbots, mevblocker, publicnode, drpc). - Candidate set: `eth_getLogs` for VLNS ERC-721 `Transfer` over the window (481 transfers, 356 blocks). Any qualifying `OrderFulfilled` must move the token in the same transaction, so those blocks are a superset — coverage of every candidate block was asserted after range-merging. - `eth_getLogs` for `OrderFulfilled` (topic0 `0x9d9af8e3…`) on Seaport 1.5 and 1.6 over those blocks (1125 events), decoded in-process into `SpentItem[] offer` / `ReceivedItem[] consideration`. 27 events hold exactly one NFT item, an itemType-2 VLNS token, and are paid wholly in ETH/WETH: 26 listing fills (price = sum of all consideration, fees included) and 1 bid fill (price = the offer amount). None were dropped as bundles, ERC-1155, multi-NFT or other currency. - Cross-checks: all 27 fills and their per-event prices reproduced identically from `ethereum-rpc.publicnode.com` (a different operator); for the one transaction paying ETH directly to Seaport for a single fill, summed consideration equalled the transaction value exactly. One judgement call, stated in `definitions` and `notes`: tx `0x88297a84…` is a matched-order pair — one economic sale of token 9512 reported as two `OrderFulfilled` events (bid leg 0.0106, listing leg 0.010494). The brief defines a sale as the event, so both count; de-duplicating would give 46095923076923076 (bid leg kept) or 46100000000000000 (listing leg kept) instead. The brief carries `"evidence": "panel"`, so the recipe is the `panel` kind — no catalogue recipe can sum a value inside Seaport's dynamic item arrays — and its `source` names the endpoint, topic, both contracts and the exact block range to re-read. `artifacts/answer.json` is left untracked.

`check-answer.mjs` prints `ok`. `artifacts/answer.json` is written and left untracked (it's ignored by git, so nothing was added). **Answer: `44781259259259259` wei** (~0.0448 ETH) How it was computed: - Scanned every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly blocks 26019452–26026608 on `ethereum-rpc.publicnode.com` (chain id 1, closing hash matched the pin; hash also confirmed on `eth.drpc.org`). 20 chunks of 400 blocks, none refused — 12,232 logs, whole scan. - Decoded each log's offer/consideration arrays with a scratch Node script in `test/scratch/` (the delivered `scan.mjs` can't decode the dynamic arrays) and applied the brief's definitions: exactly one ERC-721 of `0x357b…f626`, no other NFT, listing fills summed over all-ETH/WETH consideration, bid fills taking the offer amount. - 27 qualifying sales (26 listings, 1 WETH bid, all on Seaport 1.6, none excluded), sum 1,209,094,000,000,000,000 wei → floor(sum/27) = 44781259259259259. Since the brief is `evidence: "panel"`, the recipe is `{kind: "panel", source: <the eth_getLogs query>}`; the open choices (how bundles, multi-item offers and native-vs-WETH are treated) are spelled out under `definitions`, and the endpoints and counts are in `notes`.
