Created [artifacts/answer.json](artifacts/answer.json). Average: **42,783,665,087,599,275 wei** across **31 qualifying sales**. Includes definitions and RPC reproduction details. Required checker printed `ok`.

Created `artifacts/answer.json` with the reproducible calculation. Average: **42,783,665,087,599,275 wei** across **31 sales**. Required validator printed `ok`.

The average fwogs sale price over blocks 26019451–26026607 was **42783665087599275 wei**, about 0.0428 ETH. `check-answer.mjs` prints `ok` for `artifacts/answer.json`. - **How I computed it:** I pulled Seaport 1.5 and 1.6 `OrderFulfilled` logs over exactly the pinned blocks from `https://ethereum-rpc.publicnode.com`. The chain id and the closing block hash matched the pin. I only used that one endpoint, so I did not cross-check the hash on a second operator. I decoded 12,231 logs and applied the request's definitions. - **Result:** 31 logs touched the collection and all 31 qualified: 22 listing fills and 9 bid fills. Their prices sum to 1326293617715577541 wei, and dividing by 31 and rounding down gives the figure above. - **Recipe kind:** The brief is marked `"evidence": "panel"`, so the checker only accepts a `panel` recipe. The recipe's `source` is the RPC URL and the exact query. The definitions and notes in the file state the sale and price rules and how the figure was computed. - **Scratch script:** It is at `test/scratch/sales.mjs`, which is not submitted. The submitted `artifacts/answer.json` is untracked.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 42783665087599275 wei** (≈0.042784 ETH) — the floor of 1326293617715577541 wei over 31 qualifying Seaport sales. How it was computed, over exactly blocks 26019451–26026607: 1. **Pin confirmed first** — `eth_chainId` = 1 and block 26026607's hash `0x8a84f5aa…cdec2` matched on two independent operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`). 2. **Candidate narrowing** — `eth_getLogs` for the ERC-721 `Transfer` topic on `0x8fe1a377…9cd8` gave 366 four-topic transfers across 279 blocks. Any Seaport fill of one of these tokens must move it, so those blocks are a strict superset of the blocks holding a qualifying `OrderFulfilled`. This turned a full 24-hour Seaport scan into 132 small ranges. 3. **Decode and filter** — `OrderFulfilled` (`0x9d9af8e3…6f31`) on Seaport 1.5 and 1.6, kept for those transactions (38 logs), decoded as `(bytes32, address, SpentItem[], ReceivedItem[])`. 31 qualified (22 listing fills, 9 bid fills); the other 7 were other collections' fills riding in the same transactions. No bundle, ERC-1155, or non-ETH/WETH fill of this collection occurred, so those exclusions were inert. 4. **Truncation guard** — the whole computation was repeated on the second operator with different ranges (250-block chunks for transfers, one block at a time for Seaport) and returned the same 366 transfers, 38 logs, 31 sales and the same total to the wei. Two judgement calls worth flagging, both stated in `definitions`: - **matchOrders double-emit.** Two fills (token 3504 and 2531) emit two qualifying logs each — the bid side gross and the listing side net of the 6.5% fee. The brief defines a sale *as the `OrderFulfilled` event*, so both halves were counted. Deduping to one log per NFT would give 29 sales and 43212986817778535 wei; I went with the literal definition since that is what the brief fixes and what a mechanical implementation produces. - **Recipe kind.** The brief carries `"evidence": "panel"`, and `check-answer.mjs` refuses any non-`panel` recipe on such a brief, so the recipe is `{kind: "panel", source}` with the RPC endpoints and exact log filter in `source` — even though the figure itself is read from chain, not from a marketplace API. Scratch scripts are in `test/scratch/` (not submitted); nothing outside `artifacts/answer.json` was created in scope, and the file is left untracked.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price is **42783665087599275 wei**, about 0.0428 ETH. - **Data:** I pulled Seaport 1.5 and 1.6 `OrderFulfilled` logs over blocks 26019451 to 26026607 from `https://ethereum-rpc.publicnode.com`. That is 12,231 logs with no duplicates, and no chunk needed halving. The closing block hash matched the pin on both publicnode and flashbots. - **Filtering:** 31 logs had exactly one fwogs ERC-721 item and no other NFT. All 31 qualified: 22 were listing fills and 9 were bid fills. None were bundles, and none were paid in tokens other than ETH or WETH. - **Result:** the prices sum to 1326293617715577541 wei, and dividing by 31 and rounding down gives the figure above. - **Recipe:** the brief is `evidence: panel`, so the recipe is `kind: panel` with the RPC and event details as the source URL. It is not something the deployer can rerun mechanically. The five recipe kinds cannot express "decode, filter, average", so the reproducible detail is in `notes` and `definitions`. - **Script:** `scan.mjs` can't decode the item arrays in these events, so I used my own decoder at `test/scratch/fwogs.mjs`. It isn't submitted. - **Git:** `artifacts/answer.json` is untracked, as the task asked.

Created [artifacts/answer.json](artifacts/answer.json) with the reproducible RPC computation. Average: **42,783,665,087,599,275 wei** across **31 sales**. Reproduction check passed; the required validator printed `ok`.

`check-answer.mjs` prints `ok`. Summary: - Scanned Seaport 1.5/1.6 `OrderFulfilled` logs over the pinned blocks (26019451–26026607, hash confirmed) on two independent endpoints (flashbots, mevblocker) — identical results. - Decoded each log's offer/consideration items, kept fills with exactly one fwog ERC-721 item and no other NFT, paid entirely in ETH/WETH. - 31 qualifying sales, sum 1,326,293,617,715,577,541 wei, average (floor) = **42,783,665,087,599,275 wei**. - Written to `artifacts/answer.json` as a `panel` recipe (required since the brief sets `"evidence": "panel"`), with the exact `eth_getLogs` query and decoding logic recorded so it's reproducible.

Created [artifacts/answer.json](/root/.identitymd/work/ba5a70c2-4626-4bba-9020-9880760efc2e/020f9cd3-a7b7-4fd1-884a-e2ffed3b0459/artifacts/answer.json). Average sale price: `42783665087599275` wei across 31 qualifying sales. Validation passed: `check-answer.mjs` printed `ok`.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price of fwogs over blocks 26019451 to 26026607 is 42783665087599275 wei. - **Scan:** I fetched all 12,231 OrderFulfilled logs from Seaport 1.5 and 1.6 over the pinned blocks from `https://ethereum-rpc.publicnode.com`. The scan confirmed chain id 1 and the pinned closing block hash on that endpoint. I did not check the hash on a second endpoint. - **Sales:** 31 fills qualified under the brief's definitions, with a total of 1326293617715577541 wei. No fill was dropped for being paid in a token other than ETH or WETH. - **Answer:** 1326293617715577541 divided by 31, rounded down, gives 42783665087599275, which is the `answer`; the total is stored as `figure`. - **Recipe:** The brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for those. So the recipe names the endpoint, both Seaport contracts, the OrderFulfilled topic and the block range as its source. Nothing in it is rerun automatically. - **Decoding:** `scan.mjs` can't decode Seaport's nested arrays, so I wrote my own decoder in `test/scratch/s.mjs`. - **Earlier failure:** The earlier failed attempt never produced `artifacts/answer.json`, which is what the daemon error was about. The file exists now and is untracked.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **42783665087599275 wei** (about 0.0428 ETH) per fwog sale. - **Method:** I scanned Seaport 1.5 and 1.6 `OrderFulfilled` logs over blocks 26019451 to 26026607 from `https://ethereum-rpc.publicnode.com`, decoded the offer and consideration items myself, and applied the request's definitions. The endpoint returned chain id 1, and the closing block hash matched the pin. - **Result:** Of 12,231 logs, 31 were qualifying fwog sales, and none was excluded for being paid in another token. The prices sum to 1326293617715577541 wei, and dividing by 31 and rounding down gives the answer. - **Recipe kind:** The brief says `"evidence": "panel"`, and the check rejects any recipe that isn't `panel` in that case. The recipe is therefore `panel`, with the RPC endpoint and topic as its source URL. The deployer can't rerun the computation from that recipe. The method is described in `notes` instead. - **Scan script:** I used my own script in `test/scratch/fwog.mjs` (not submitted) rather than `scan.mjs`, because `scan.mjs` can only sum or rank flat log fields and can't read Seaport's nested item arrays. - **Git status:** `git status` is clean because the answer file is untracked output.

**Answer: 42783665087599275 wei** — 31 qualifying fwogs fills (22 listing, 9 bid), sum 1326293617715577541 wei, over blocks 26019451–26026607; pinned closing hash confirmed on the keyed route and on `ethereum-rpc.publicnode.com`. `check-answer.mjs` prints `ok` for `artifacts/answer.json` (left untracked).

The average fwogs sale price over the pinned window was **42783665087599275 wei** (about 0.0428 ETH). The answer is in `artifacts/answer.json`, and `check-answer.mjs` prints `ok`. - **How:** the delivered `scan.mjs` can only add up one number per log, and it can't unpack Seaport's lists of offer and payment items. So I wrote a small decoder in `test/scratch/`. It pulled every `OrderFulfilled` log from both Seaport addresses over blocks 26019451–26026607 on `https://ethereum-rpc.publicnode.com`, in 500-block chunks and halving any chunk the endpoint refused. That came to 12,231 logs. - **Result:** 31 events met the definitions (22 were listings bought, 9 were accepted bids). None involving the collection had to be excluded. The prices add up to 1326293617715577541 wei, which is the `figure` field. Divided by 31 and rounded down, that gives the answer. - **Checks:** the endpoint returned chain id 1, and the closing block hash matched the pin there and on `https://rpc.flashbots.net`. - **Not cross-checked:** I haven't confirmed the log count on a second endpoint, so I can't rule out that publicnode left some logs out. The drpc scan failed partway. The blastapi scan was still running with no output when I wrote the answer, so I have no second total. - **Recipe:** the request is marked `"evidence": "panel"`, so the recipe is `kind: "panel"`, as the checker requires. Its `source` names the endpoint and the event. `definitions` spells out exactly what counts as a sale and a price, including that each qualifying event counts once. `artifacts/answer.json` is not tracked by Git, as the task requires.

I've written `artifacts/answer.json`. The average fwogs sale price over blocks 26019451–26026607 is **42783665087599275 wei** (about 0.0428 ETH), and `check-answer.mjs` prints `ok`. **How I got the number:** - I fetched every `OrderFulfilled` log from both Seaport contracts (1.5 and 1.6) over exactly the pinned blocks, from `https://ethereum-rpc.publicnode.com` in 500-block chunks. That came to 12,231 logs, and every chunk was far below any size limit. - The chain id is 1. The closing block's hash matches the pin on that endpoint and on a second operator, `https://rpc.flashbots.net/fast`. - 31 fills qualified: 22 fills of a listing and 9 fills of a bid. None were dropped for paying in a token other than ETH or WETH. - The prices add up to 1326293617715577541 wei (stored as `figure`). Divided by 31 and rounded down, that gives the answer. Single prices range from about 0.0362 to 0.0469 ETH, so the average looks reasonable. **Choices a reviewer should know about:** - **Recipe kind:** the request is marked `"evidence": "panel"`, so the checker only accepts a `panel` recipe. Its `source` names the endpoint, the event topic, both Seaport addresses and the block range. - **Script used:** I didn't use `scan.mjs`. It can only count, sum or rank one field, and this average needs each event decoded and filtered first. I used a small Node script of my own in `test/scratch/`, which is not submitted; the method is described in `notes`. - **Stated under `definitions`:** - Anything with item type 2 or higher counts as "another NFT", which disqualifies a fill. - Each qualifying event counts as one sale, even when several are in the same transaction. - For a bid fill, the price is the bidder's full offer, since fees are paid out of it. I checked the file with `check-answer.mjs`; the only check of the number itself is the price range above. The earlier attempt failed because the `artifacts/` folder was never created. It now exists, and `answer.json` is left out of git so the daemon can upload it. I didn't change any other files.

Done. `artifacts/answer.json` is written, passes `check-answer.mjs` (`ok`), and is left untracked (the directory is gitignored, so nothing is staged). **Answer: `42783665087599275` wei** (≈0.04278 ETH) — the floored mean of 31 qualifying fwog sales. How it was computed: - Scanned `eth_getLogs` on `https://rpc.flashbots.net/fast` (chain id 1, closing block 26026607 hash matched the pin; also confirmed on `ethereum-rpc.publicnode.com`) for the `OrderFulfilled` topic on both Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607. 8 chunks of 1000 blocks, no refusals, 12,231 logs total. - The bundled `scan.mjs` can only sum a fixed data word, so I wrote a dependency-free decoder in `test/scratch/fwog-avg.mjs` (same halving-on-refusal loop) that decodes the dynamic `offer`/`consideration` arrays and applies the brief's definitions per event, printing only totals. - 31 events touched the collection (all on Seaport 1.6) and all 31 qualified: 22 listing fills (20 in native ETH, 2 in WETH) and 9 WETH bid fills. No bundles, ERC-1155s, or other-token payments. Sum 1,326,293,617,715,577,541 wei ÷ 31 → floored. - The one open reading — whether a bid fill's non-NFT consideration must also be ETH/WETH — gives the same result either way here; both readings are stated under `definitions`. - Since the brief is `"evidence": "panel"`, the recipe is `{kind: "panel", source: <RPC + exact getLogs filter>}`, with the full decoding procedure in `notes` so the deployer can rerun it.

Created `artifacts/answer.json` with the average **42783665087599275 wei**, computed from 31 qualifying sales, and reproduction details. Independent decoding agreed. The required checker printed `ok`.

`artifacts/answer.json` is written (untracked, excluded by the repo's own `.git/info/exclude`) and `check-answer.mjs` prints `ok`. ## What the answer is **42783665087599275 wei** (~0.042784 ETH) — the floor mean of **31 qualifying sales** summing **1326293617715577541 wei** over blocks 26019451–26026607. ## How it was computed - **Pin confirmed** on two operators: `eth_getBlockByNumber(0x18d226f)` returns the pinned hash on `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`, both `eth_chainId 0x1`. The window is exactly 24h (2026-09-20T14:53:47Z → 2026-09-21T14:53:47Z). - **Discovery:** `eth_getLogs` for `Transfer` on the collection over the pinned blocks → 366 ERC-721 transfers in 304 txs. Every Seaport fill of the collection must move the token, so no qualifying event can lie outside that set. Receipts of those txs → 38 `OrderFulfilled` logs from Seaport 1.5/1.6; 31 qualify, 7 are other collections swept in the same call. - **Decoding** was done in `test/scratch` (scan.mjs can sum a fixed data word but cannot decode `OrderFulfilled`'s two dynamic struct arrays); I used its `--keccak` for topic0 and reproduced its chunk-and-halve behaviour. Totals only, never logs. - **Verification:** for the five single-sale txs sent straight to Seaport 1.6, the decoded listing price equals `tx.value` to the wei — the decode is right and fees are inside the price. All 31 were on Seaport 1.6; none paid in a token other than ETH/WETH. ## The one judgement call Two txs contain a Seaport *match*: a bid fill and a listing fill of the same token id, the listing side carrying the seller's net (93.5% of the bid). The brief defines a sale per `OrderFulfilled` event, so both halves count — that is what I did, and it is stated under `definitions.matched-pairs`. Collapsing each pair to its bid half would give 29 sales and 43212986817778535 wei; I did not add a dedupe rule the brief does not state, since the panel is compared against the pinned definitions. The recipe is `{ kind: "panel", source }` because the brief carries `"evidence": "panel"` — the checker refuses a chain recipe here — but the figure itself is read from chain, and the `source` names the endpoint, the topic, both Seaport contracts and the block range so it can be re-run.

`artifacts/answer.json` is written, and the answer check prints `ok`. The average sale price is 42783665087599275 wei, over 31 qualifying sales totalling 1326293617715577541 wei. - **Recipe kind:** The recipe is `panel`, because the brief is marked `evidence: panel` and that is the only kind allowed for it. The fact is on chain, so the recipe's `source` is the RPC endpoint I read from, `https://ethereum-rpc.publicnode.com`, and `notes` gives the method. The deployer can't rerun a `panel` recipe; the panel's agreement is the evidence. - **Method:** I did not use `scan.mjs`. It filters only on the Seaport event itself and can't apply the collection and price rules. I pulled the collection's ERC-721 `Transfer` logs over blocks 26019451 to 26026607 (366 transfers in 304 transactions). I then decoded every Seaport 1.5 and 1.6 `OrderFulfilled` log in those transactions' receipts and applied the pinned sale and price definitions. - **Coverage:** Every fill of a fwogs token moves it with a `Transfer`, so this should catch every qualifying sale. I did not cross-check it against a full scan of all Seaport logs. - **Pin check:** I confirmed the closing block hash matches the pin on that one endpoint, and did not check a second one. The scratch script is `test/scratch/s.mjs`; it isn't submitted.
