Check passes. Computed average sale price of Gemesis: **10198149999999500 wei** (20 qualifying sales, sum 203962999999990000 wei), written to `artifacts/answer.json` with a `panel` recipe (required since the brief's `evidence` is `"panel"`) citing the on-chain source and endpoints used.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It reports an average Gemesis sale price of **10198149999999500 wei**, about 0.0102 ETH. - **Sales counted:** 20 qualifying sales in blocks 26019452–26026608. Six were listing fills and 14 were bid fills. None were excluded. - **Total and average:** the 20 prices sum to 203962999999990000 wei, and the average is that divided by 20, rounded down. - **How I computed it:** the provided `scan.mjs` can't decode Seaport's nested offer and consideration arrays. So I wrote a small Node script in `test/scratch/`, which isn't submitted. It scanned 12,232 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over exactly the pinned blocks, then applied the request's sale and price definitions. - **Endpoints:** the scan ran on `https://rpc.flashbots.net/fast`, where chain id 1 and the pinned closing hash matched. `https://ethereum-rpc.publicnode.com` confirmed the same closing hash. - **Recipe:** the request has `"evidence": "panel"`, so the recipe kind is `panel`. Its `source` describes the RPC scan and the decoding rules. - **Bid fills:** I read the bid definition as "price is the offer amount", so other consideration items in a bid fill are not checked. This assumption is stated in `notes`. - **Earlier failure:** the previous attempt failed because the `artifacts/` directory didn't exist, so I created it before writing. - **Git:** `git status` shows nothing for `artifacts/answer.json`, and I did not check why. I did not stage or commit anything.

Confirmed: `artifacts/` and `test/` are git-ignored, so `artifacts/answer.json` stays untracked as required, ready for the daemon to pick up separately. ## Summary Computed the answer directly from Ethereum mainnet chain data since the brief marks this `"evidence": "panel"`: - Scanned `OrderFulfilled` logs from both Seaport 1.5 and 1.6 over blocks 26019452–26026608 (12,232 logs) via `https://ethereum-rpc.publicnode.com`, hand-decoding the ABI-encoded offer/consideration arrays (no library needed since their struct fields are all static). - Applied the brief's definitions: exactly one ERC-721 item of Gemesis, no other NFT in the fill, payment entirely in ETH/WETH (listing fills sum all consideration amounts; bid fills use the offer amount). - Found 20 qualifying sales summing to 203962999999990000 wei → average **10198149999999500 wei** (exact, no remainder). - Cross-checked chain id and the pinned closing block hash on a second, independent endpoint (`rpc.mevblocker.io/fast`). Wrote `artifacts/answer.json` with a `panel` recipe (the only kind valid for a panel-evidence question) naming the on-chain source, and `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs` prints `ok`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average Gemesis sale price on OpenSea over blocks 26019452 to 26026608 is **10198149999999500 wei**. - **Scan:** I scanned 12,232 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over exactly the pinned window, using my own scan script in `test/scratch/` rather than `scan.mjs`. `scan.mjs` cannot decode Seaport's nested item arrays. I read from `ethereum-rpc.publicnode.com`, whose chain id and closing block hash matched the pin. - **Second endpoint:** `rpc.mevblocker.io/fast` returns the same closing hash. - **Result:** 20 sales qualified, summing to 203,962,999,999,990,000 wei. That divides exactly by 20, so nothing was rounded. - **Recipe kind:** it is `panel`, because the brief has `"evidence": "panel"` and `check-answer.mjs` rejects any other kind for it. The recipe's `source` names the RPC call and filter used, so the figure can be rerun from public data. - **Definitions:** they are stated in the file and follow the brief's own wording.

The average sale price of Gemesis over the pinned window is **10198149999999500 wei** (about 0.0102 ETH), across 20 sales totalling 203962999999990000 wei. The answer is in `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. **How I got it** - I wrote my own scanner in `test/scratch/scan.mjs`. The supplied `scan.mjs` can only add up one fixed number per log. Seaport's offer and consideration are variable-length lists, so it can't decode them. - Endpoint: `https://ethereum-rpc.publicnode.com`. It returned chain id 1, and block 26026608's hash matched the pinned hash. `https://eth.drpc.org` returned the same hash. - I fetched OrderFulfilled logs from both Seaport contracts over exactly blocks 26019452–26026608, in 500-block chunks, halving any chunk that failed. That gave 12,232 logs with no duplicates. - 20 of those logs qualify under the request's definitions: - 14 are the buyer's side of a fill, where the order offers ETH or WETH; the price is that amount. - 6 are the seller's side, where the order offers the NFT; the price is the sum of the ETH/WETH payments. - None was excluded for being paid in another token. - The average is the total divided by 20, rounded down. **One judgement call that changes the answer:** in 4 transactions (`0xdacf4e1f22…`, `0xc01d12bf44…`, `0xe8d32f8dbf…`, `0xfcbec6b70a…`), a single sale produced two qualifying events. One is the buyer's full offer; the other is the seller's proceeds after fees. The request defines a sale as each qualifying event, so I counted both. Counting only the buyer's side would give 16 sales and an average of 10167499999999375 wei. Other panel members who dedupe these will get that number instead, so this is where disagreement is most likely. The notes in the answer file say so. **Other things to know** - The request is marked `"evidence": "panel"`, so the recipe has to be `panel` with a `source`. I wrote the endpoint, the event signature, both contracts and the block range into it, because there's no recipe kind that reruns Seaport decoding. - I ran the scan once and did not repeat it on a second endpoint. - `artifacts/answer.json` is the only file I created outside `test/scratch/`, and it is not committed.

`ok`, exit 0. ## Result **Average Gemesis sale price over blocks 26019452–26026608: `10198149999999500` wei** (≈0.01019815 ETH), from 20 qualifying Seaport fills totalling 203962999999990000 wei — an exact division, so no rounding applied. How it was computed: - Pin and chain confirmed with `scan.mjs` on `ethereum-rpc.publicnode.com` (chainId 1, `pinned: true`), and the closing hash re-read from three other operators (merkle, flashbots, drpc). - Any ERC-721 fill of the collection must emit a collection `Transfer` in the same tx, so the 18 blocks holding the window's 24 Transfers bound the search. Fetched `OrderFulfilled` from Seaport 1.5 and 1.6 in exactly those blocks (54 events), decoded the dynamic `offer[]`/`consideration[]` structs in process, printed only totals. - 20 events qualified: 14 bid fills (price = the single WETH offer amount) and 6 listing fills (price = full consideration sum, fees included). Nothing rejected for a non-ETH token, bundle, or ERC-1155 leg. Two judgement calls, both stated under `definitions`: - `evidence: "panel"` in the brief forces `{kind: "panel", source}`; the chain recipes can't express this anyway, since the collection isn't an indexed topic and price isn't a fixed data word. The `source` names the exact logs a rerun needs. - An OpenSea accept-offer match emits **two** qualifying events for one token (bidder's order + seller's mirror, e.g. 9500000000000000 and 9405000000000000 at block 26020758). The brief defines a sale as a per-event predicate and gives a price rule for each shape with no collapsing rule, so both are counted. This is the main place a panel could diverge, and it's called out explicitly in `definitions` and `notes`. `artifacts/answer.json` is written (5684 bytes) and untracked.

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 10198149999999500 wei** (≈0.0101981 ETH), from a sum of 203962999999990000 wei over 20 qualifying fills. How it was computed: - Scanned all 12,232 Seaport 1.5 + 1.6 `OrderFulfilled` logs over blocks 26019452–26026608 inclusive from `https://ethereum-rpc.publicnode.com` (chain id and the pinned closing hash `0x84272223…` confirmed on that endpoint first; `eth.drpc.org` refused this `eth_getLogs` filter outright, so it was dropped). - Decoded each log's `offer`/`consideration` arrays and kept fills holding exactly one ERC-721 item of `0xbe93…a826` and no other NFT: 14 bid fills (price = the WETH offer amount) and 6 listing fills (price = the full consideration sum, all items ETH/WETH, fees included). No bundles, ERC-1155 fills, or foreign-token payments appeared. - Completeness cross-check on a second path and a second provider: all 24 Gemesis ERC-721 `Transfer`s in the window (18 blocks), then Seaport logs re-read block-by-block from `eth-mainnet.public.blastapi.io` and re-decoded — identical 20 events, identical sum. That rules out a silently truncated chunk. One judgement call worth your attention, stated in `definitions.sale_unit`: 4 of the 20 events are the listing half of a matched fill whose bid half is also in the set (same tx, same tokenId). The request defines a sale as an `OrderFulfilled` event, so I counted each event once, per the literal definition. The deduplicated reading — one trade per tx+tokenId, keeping the gross bid-side price — yields 16 sales, sum 162679999999990000, average 10167499999999375; that alternative is recorded in both `definitions` and `notes` so a reader comparing panel answers can see which branch I took.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price of Gemesis over blocks 26019452–26026608 is **10198149999999500 wei**. - **Sales counted:** 20 qualifying Seaport 1.5 and 1.6 sales, totalling 203962999999990000 wei. - **Excluded:** none of the fills I decoded was excluded. - **Window check:** the chain id is 1 and the hash of block 26026608 matches the pinned hash. I checked both on publicnode only, not on a second operator's endpoint. - **How I computed it:** I fetched every Transfer log of the collection in the window (24 logs, 18 transactions), decoded the Seaport `OrderFulfilled` events in those transactions' receipts, and applied the definitions. `scan.mjs` can't decode Seaport's nested arrays, so I used my own script (`test/scratch/run.mjs`, not submitted). - **Recipe kind:** it is `panel`, because the brief says `"evidence": "panel"` and the checker rejects any other kind for such a brief. The source is the publicnode endpoint plus the event and contract addresses. The deployer can't rerun a `panel` recipe, so the answer rests on agreement with the other panel members. - **Not verified:** I didn't check how many of the 20 sales were listings versus bids, or ETH versus WETH, so the notes make no claim about that split.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. **Answer:** the average Gemesis sale price on OpenSea over blocks 26019452–26026608 is **10198149999999500 wei**. - **Scan:** I fetched all 12,232 Seaport `OrderFulfilled` logs from both Seaport 1.5 and 1.6. The closing block hash matched the pin. - **Sales:** 20 fills qualified under the request's definitions, summing to 203962999999990000 wei. - **Recipe kind:** I used a `panel` recipe with the RPC source named, because the brief says `evidence: panel`. The chain recipes (`log-sum` etc.) can't express the decode-and-filter this needed. The deployer can't rerun a `panel` recipe automatically, so the answer stands on panel agreement. - **Endpoints:** I used publicnode as the main endpoint, with flashbots and mevblocker as fallbacks. I didn't use the provided `scan.mjs`, since it can't decode Seaport's nested items. I wrote my own decoder in `test/scratch/s.mjs`, which is not submitted. - **Hash check:** I only checked the closing hash on the publicnode endpoint. I didn't check it on a second operator's endpoint.

Answer: **10198149999999500 wei** — 20 qualifying Seaport `OrderFulfilled` fills of Gemesis in blocks 26019452–26026608, summing to 203962999999990000 wei. `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` prints `ok`.

Created `artifacts/answer.json` with average **10,198,149,999,999,500 wei** across 20 qualifying sales. The included reproduction code matched the answer from public RPC data. The required validator printed `ok`.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average sale price of Gemesis over blocks 26019452 to 26026608 is **10198149999999500 wei**. That is 203962999999990000 wei across 20 qualifying sales (6 listing fills, 14 bid fills), rounded down. - **Scan:** I fetched every Seaport 1.5 and 1.6 `OrderFulfilled` log in the pinned range, 12,232 in all, and decoded them under the brief's sale and price definitions. Every one of the 20 logs that touched Gemesis qualified. - **Cross-check:** The closing hash matched the pin on all three endpoints I tried (publicnode, flashbots, mevblocker). I ran the scan again on flashbots alone and on mevblocker alone. Both gave the same 12,232 logs, 20 sales and sum. - **Recipe kind:** The brief has `"evidence": "panel"`, and `check-answer.mjs` rejects any recipe other than `panel` for such a brief. The recipe is therefore `panel`, with the endpoint and the Seaport addresses in `source`. The deployer won't be able to rerun it as a log recipe. The exact procedure is in `notes` and `definitions`. - **Scan script:** I wrote my own scan script (`test/scratch/sales.mjs`) instead of using `scan.mjs`, because it only sums fields and can't decode the nested offer and consideration items. It stays in `test/scratch/` and isn't submitted.

Completed `artifacts/answer.json`. Computed result: `10198149999999500` wei. Validation passed: ```text ok ``` I cross-checked the scan on Flashbots and PublicNode; both returned the same pinned block hash, 12,232 Seaport logs, 20 qualifying Gemesis sales, total `203962999999990000` wei, and the same rounded-down average.

I wrote `artifacts/answer.json`. The average Gemesis sale price over blocks 26019452–26026608 is **10198149999999500 wei** (about 0.0102 ETH), and `check-answer.mjs` prints `ok`. - **How I got it:** I confirmed chain id 1 and the pinned closing block hash on `https://ethereum-rpc.publicnode.com`. I then pulled all 12,232 Seaport 1.5/1.6 OrderFulfilled logs over exactly the pinned blocks and decoded the offer and consideration items myself. `scan.mjs` can't read those item lists, so I used a scratch script instead. - **Result:** 20 events qualify under the brief's definitions: 6 listing fills and 14 bid fills. None were dropped for being paid in another token. They total 203962999999990000 wei, and that sum divided by 20, rounded down, is the answer. - **Recipe:** the brief marks this as a panel-evidence question, so the recipe is `panel`. Its source names the RPC endpoint, both Seaport addresses, the event topic and the block range. **One judgement call:** in 4 transactions, both sides of a single matched sale emit a qualifying event. One is the buyer's bid paid in WETH, the other the seller's order giving the NFT for the net amount. The brief counts every qualifying event, so I counted both. If other panel members count each sale once, they'd average 16 sales and get a different figure. I noted this in `notes`.

The recipe is therefore `panel`, with `https://ethereum-rpc.publicnode.com` as its source URL. - **What I ran:** I fetched the collection's Transfer logs over 26019452–26026608, which gave 24 logs in 18 blocks. I then pulled the Seaport 1.5 and 1.6 OrderFulfilled logs in only those blocks and decoded them by hand. The script is in `test/scratch/s.mjs`; it isn't submitted. - **Why those blocks only:** any sale of the NFT must emit a Transfer in the same block. That is much cheaper than scanning every Seaport log across the whole window. - **Not the delivered scan script:** `scan.mjs` can't decode these events, so I wrote my own decoder. - **Checks:** on that endpoint, `eth_chainId` returned 1 and the closing block hash matched the pin. I did not check the hash on a second operator's endpoint. - **Definitions:** I applied the request's own definitions of sale, price and average, and copied them into `definitions`.

Done. `artifacts/answer.json` is written, passes the checker (`ok`), and is left untracked with no tracked files modified. **Answer: 10198149999999500 wei** (~0.0102 ETH) — the average Gemesis sale price on OpenSea over pinned blocks 26019452–26026608. How it was computed, per the brief's pinned definitions: - Fetched all `OrderFulfilled` logs (topic0 `0x9d9af8…6f31`) from Seaport 1.5 and 1.6 via `https://ethereum-rpc.publicnode.com`, confirming `eth_chainId = 1` and the pinned closing hash there, plus a one-call cross-check of the same hash on `https://rpc.flashbots.net/fast`. 12,232 logs total in the window. - Decoded each log's offer/consideration item arrays and kept fills containing exactly one ERC-721 of the collection and no other NFT: **20 qualifying sales** — 6 listing fills (price = sum of all consideration amounts, all of which were ETH/WETH, fees included) and 14 bid fills (price = the single ETH/WETH offer amount). Nothing was excluded for bundles, multi-item offers, or non-ETH/WETH payment in this window. - Sum 203,962,999,999,990,000 wei ÷ 20, rounded down → 10,198,149,999,999,500. Since the brief marks this `"evidence": "panel"` (Seaport item-array decoding isn't expressible in the rerunnable chain-recipe catalogue), the recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}`, with every choice the request left open (the literal per-event reading, "no other NFT" as no other itemType ≥ 2, single-item-offer requirement, dedup and floor rounding) stated under `definitions` and the full method in `notes`. The scratch script lives in `test/scratch/compute.mjs`, which is deleted before submission and needs no cleanup.

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 10198149999999500 wei** (≈0.0101981 ETH), from a sum of 203962999999990000 wei over 20 qualifying fills. How it was computed, over exactly blocks 26019452–26026608: 1. Confirmed `eth_chainId` = 1 and the pinned closing hash `0x84272223…bf3f` on two independent operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`). 2. Scanned the collection's `Transfer` logs with the delivered `scan.mjs`: 24 logs across 18 blocks. Every Seaport ERC‑721 fill moves the token, so those 18 blocks are a superset of the qualifying fills — that keeps the Seaport read to 54 `OrderFulfilled` logs instead of a day of mainnet Seaport traffic. 3. Decoded those events in-process (`SpentItem[]`/`ReceivedItem[]` sit in dynamic arrays, which `scan.mjs` cannot sum) and applied the brief's rules: 20 qualify — 14 bid fills, 6 listing fills, all on Seaport 1.6; Seaport 1.5 emitted none. Nothing was excluded for a non‑ETH/WETH payment token. One judgement call, stated under `definitions.sale_unit` and in `notes`: four accept-offer transactions emit both sides of a matched order (the bid's gross amount and the counter listing's net leg, exactly 99% of it — the OpenSea fee). The brief defines a sale as an `OrderFulfilled` event, so I counted both, per its literal wording. Read instead as one sale per token movement at the gross amount, the figure would be 10167499999999375 over 16 sales; that alternative is recorded in the answer so a disagreeing panel member's number is identifiable rather than mysterious. The recipe is `{ kind: "panel", source: … }`, which is what this brief's `"evidence": "panel"` requires — and is also the honest kind here, since no chain recipe in the catalogue decodes Seaport item arrays or takes a mean.

Created [artifacts/answer.json](/Users/peterhucik/.identitymd/work/c216934c-30c7-4050-98ed-63b900ff40dd/36d3852f-cdd5-446e-9c61-4496e5a37d15/artifacts/answer.json). Average sale price: `10198149999999500` wei. Validator result: `ok`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 10198149999999500 wei.** That is 203962999999990000 wei summed over 20 qualifying sales, divided by 20 and rounded down (it divides exactly). Of the 20 sales, 6 were listing fills and 14 were bid fills. None were excluded as bundles, non-ETH/WETH payments or other shapes. - **Recipe kind:** the brief says `evidence: panel`, and `check-answer.mjs` requires a `panel` recipe for that. None of the catalogue's chain recipes can decode Seaport's nested item arrays, so `recipe.source` points at the public RPC and `notes` describes the computation. - **How I computed it:** I confirmed the chain id is 1 and that the closing block hash matches the pin. I pulled every Transfer log of the Gemesis contract in the window (24 logs across 18 transactions). For each transaction I decoded the Seaport 1.5 and 1.6 OrderFulfilled events from its receipt and applied the brief's sale and price definitions. Every ERC-721 fill of the collection emits a Transfer, so this catches every fill. It is not the plain `eth_getLogs` scan on the Seaport contracts that the brief's `source` definition names, but it should give the same set of sales. - **Endpoints:** everything ran on `ethereum-rpc.publicnode.com`; the fallbacks were never needed. I did not cross-check the block hash on a second operator, and I ran the scan once. - **Cleanup:** my script is in `test/scratch/gem.mjs`, which is not submitted. `git status` is clean and `artifacts/answer.json` is left untracked.
