The check passes. Summary: - Computed the average Akutars sale price on OpenSea via Seaport `OrderFulfilled` events over blocks 26019451–26026607, decoding the ABI (dynamic offer/consideration arrays) by hand since scan.mjs's `log-sum`/`log-rank` can't handle this structure. - Filtered to fills with exactly one NFT item across offer+consideration, that item being itemType 2 (ERC-721) of Akutars, priced in ETH/WETH per the brief's definitions. - Found 46 qualifying sales, sum 1218505000000000000 wei, average (floored) **26489239130434782 wei**. - Verified identically on two independent RPC operators (rpc.flashbots.net, rpc.mevblocker.io), both confirming the pinned closing block hash. - Since the brief sets `"evidence": "panel"`, wrote the recipe as `kind: "panel"` with `source` describing the on-chain read, per REFERENCE.md's rule that panel-evidence questions only take the panel recipe. - `artifacts/answer.json` written and passes `check-answer.mjs` (`ok`).

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price of Akutars over blocks 26019451–26026607 is **26489239130434782 wei**. - **Scan:** I scanned every Seaport 1.5 and 1.6 `OrderFulfilled` log in the window (12,231) from `https://ethereum-rpc.publicnode.com`. Chain id 1 and the closing block hash matched the pin. I decoded the logs with my own script, because `scan.mjs` can't read Seaport's nested arrays. - **Result:** 46 events qualified, summing to 1218505000000000000 wei. None were excluded as bundles, other-token fills or bad prices. - **Cross-check:** Every counted sale transaction has an Akutars `Transfer`, and the other `Transfer` transactions contain no Seaport fills. So the scan wasn't silently truncated. - **Counting choice:** The definition treats each `OrderFulfilled` event as one sale, so a transaction with a bid fill and a listing fill for the same token counts twice. I followed that literally and stated it under `definitions`. - **Recipe kind:** The brief says `evidence: "panel"`, and the checker requires a `panel` recipe in that case. The recipe therefore names the RPC URL as its source, while the answer itself is computed from chain data as the definitions specify. - **Left untracked:** The file is untracked and not force-added. My scratch scripts are in `test/scratch/`.

Created `artifacts/answer.json` with average **26489239130434782 wei** across 46 qualifying fills. The embedded reproduction program returned the same result from public RPC data. The required checker printed `ok`.

Created [artifacts/answer.json](/Users/peterhucik/.identitymd/work/3647b649-3027-4774-a34a-ac47093ffef5/a7ceb859-8b60-4769-b979-5fe654ee1a6a/artifacts/answer.json). Validation result: `ok`

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok`. The answer is **26489239130434782 wei**, about 0.0265 ETH. - **Result:** 46 qualifying Seaport OrderFulfilled events, summing to 1218505000000000000 wei, rounded down after dividing by 46. - **Scan:** I fetched every OrderFulfilled log from Seaport 1.5 and 1.6 over blocks 26019451 to 26026607 and decoded them locally. There were 12,231 logs in total, and none of the 46 collection events were excluded as bundles or other-token fills. - **Closing hash:** I confirmed the pinned hash on two operators, publicnode and rpc.flashbots.net. The scan ran on publicnode. - **Recipe:** The brief says `evidence: panel`, and the checker only accepts a `panel` recipe for that. So the recipe is `{kind: "panel", source: <publicnode URL>}`. The exact scan is described in `notes`. - **Double counting:** 23 of the transactions are matched bid-plus-listing trades that emit two OrderFulfilled events for one NFT transfer. I counted each event as its own sale, following the definition literally. Counting one sale per trade would give a different mean. This is stated in both `definitions` and `notes`. The scratch scripts are in `test/scratch/` and aren't submitted.

I wrote `artifacts/answer.json` with an answer of **26489239130434782** wei, and `check-answer.mjs` prints `ok`. Only that file is new; `test/scratch/` holds my scripts and is not submitted. - **Window:** blocks 26019451–26026607 on chain 1. I confirmed the chain id and that the closing block hash matches the pinned `0x8a84f5aa…`, using `ethereum-rpc.publicnode.com`. I did not check the hash on a second operator. - **Sales:** I fetched the collection's Transfer logs over the window (28 logs, 26 transactions). Then I decoded every Seaport 1.5 and 1.6 `OrderFulfilled` event in those transactions' receipts. The scan found 46 qualifying events, and none were excluded. - **Total and mean:** the prices sum to 1218505000000000000 wei, and that sum divided by 46 and rounded down gives the answer. - **Double counting:** some transactions are `matchOrders` calls that pair a listing with a bid and emit two events for the same NFT. I counted both, because the brief defines a sale as an `OrderFulfilled` event. This is stated under `definitions`. If the deployer counts one sale per token instead, its figure will differ from this one. - **Recipe:** the brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe in that case. The recipe therefore names the RPC endpoint and Seaport contracts as its source, and nothing is rerun automatically. The steps are in `notes`. I did not use `scan.mjs`. It cannot decode Seaport's nested event data, so I wrote my own scan.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average Akutars sale price over blocks 26019451–26026607 is **26489239130434782 wei**, about 0.0265 ETH. - **Sales:** 46 sales totalling 1,218,505,000,000,000,000 wei. Every OrderFulfilled event that touched Akutars qualified, so nothing was excluded. - **How I computed it:** I pulled the events from both Seaport contracts over exactly the pinned range and confirmed the chain id and the closing block hash. That was 12,231 logs, 46 of them involving the collection. I decoded them with my own script (`test/scratch/sales.mjs`), because `scan.mjs` can't decode the item arrays in that event. - **Endpoint:** only `https://ethereum-rpc.publicnode.com`. I did not rescan on a second endpoint. - **Recipe kind:** the brief says `"evidence": "panel"`, and the check requires `{ kind: "panel", source }` in that case. The recipe therefore names the RPC and event filter as its source, and the real reproduction steps are in `notes`. - **Paired prices:** many prices come in pairs at a 1:0.99 ratio, for example 6.6e15 and 6.534e15. They may be a listing fill and a bid fill for the same NFT. Each is its own event, so I counted both, as the definitions say. If the panel dedupes them, its answer will differ from this one. I said so in `notes`.

Created `artifacts/answer.json`: **26489239130434782 wei**, averaged over 46 qualifying sales. The included reproduction code returned the same result from public RPC data. The required checker printed `ok`.

I wrote `artifacts/answer.json` with an average sale price of **10819285714285714 wei**, and `check-answer.mjs` prints `ok` for it. - **How it was computed:** the sale count is 21 and the total is 227205000000000000 wei. I scanned all 12,231 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over blocks 26019451 to 26026607. I decoded the offer and consideration items by hand and kept fills of exactly one Akutars ERC-721 paid in ETH or WETH. The price rules follow the brief's definitions. - **Endpoint and pin:** I read from `https://ethereum-rpc.publicnode.com`, and the closing block hash matched the pin. I did not check the hash on a second endpoint. - **Recipe kind:** it is `panel`, not a chain recipe. The brief says `"evidence": "panel"`, and `check-answer.mjs` requires a panel recipe for such briefs. The catalogue's chain recipes also can't decode Seaport item arrays. - **Script:** the scan script is `test/scratch/s.mjs`, which is not submitted.

I've written `artifacts/answer.json`. The average Akutars sale price over blocks 26019451–26026607 is **26489239130434782 wei** (about 0.0265 ETH), and `check-answer.mjs` prints `ok`. **How I got it** - I fetched every `OrderFulfilled` event from both Seaport contracts (1.5 and 1.6) over exactly the pinned blocks, in 500-block chunks, halving any range an endpoint refused. - I decoded the events with a small Node script of my own, applying the request's definitions of a sale and a price. I didn't use `scan.mjs` because it can only add up raw data fields and can't read Seaport's nested offer and consideration lists. - Both endpoints returned chain id 1 and the pinned closing block hash. I ran the full scan on `ethereum-rpc.publicnode.com` and again on `rpc.mevblocker.io/fast`, and both gave the same numbers: 12,231 events, 46 qualifying sales, total price 1218505000000000000 wei, average rounded down. - The request is marked `"evidence": "panel"`, so the recipe has to be `kind: "panel"` with a `source`. That source names the endpoints and the scan. **One point that affects the answer:** 20 of the 46 sales are really 10 accepted offers, each producing two events in the same transaction. The bidder's event is priced at their full offer (e.g. 0.0075 WETH) and the seller's at what they received after the fee (e.g. 0.007425 WETH). The request defines a sale as an `OrderFulfilled` event, so I counted both events, as written. Counting each transaction once would give a different average. This is explained in `notes` and `definitions`. I didn't commit anything. `git status` shows nothing to commit, so `artifacts/` looks like it's ignored by git, which fits the rule that the output stays untracked. The scan script is in `test/scratch/s.mjs` and isn't part of the submission.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 26489239130434782 wei** (≈0.02649 ETH), over sum `1218505000000000000` wei / 46 qualifying fills. How it was computed, over exactly blocks 26019451–26026607: 1. **Pin confirmed** — `eth_chainId` = 1 and block 26026607 hash `0x8a84f5aa…cdec2` on four independent operators (flashbots, publicnode, drpc, mevblocker). 2. **Candidate set** — any Seaport fill of an Akutars ERC-721 must emit an Akutars `Transfer` in the same transaction, so `scan.mjs` over the collection's Transfer topic gives an exact and cheap candidate set: 28 logs, 26 transactions. 3. **Decode** — pulled those 26 receipts and decoded every `OrderFulfilled` from Seaport 1.5/1.6. 2 transactions had no Seaport log; the other 24 emitted 54 events, of which 8 were fills of a different collection inside the same aggregator transaction. 46 qualified (21 listing fills, 25 bid fills, 46 distinct order hashes, 23 token ids). No non-ETH/WETH payment, no bundle, no ERC-1155. One judgement call is worth flagging: 21 of the transactions were **matched orders**, where Seaport emits two qualifying `OrderFulfilled` events for one economic trade (bid side and listing side). The brief defines a sale as *an event* and gives a price rule for each side with no rule for collapsing a pair, so I counted both, as written. The alternative reading — one trade, taking the bid side's fee-inclusive amount — gives 25 sales and **39652000000000000 wei**; that figure is recorded in `definitions` and `notes` so the panel can see which reading I took. Because the brief carries `"evidence": "panel"`, the checker requires the `panel` recipe kind (a chain recipe is rejected outright, and `log-sum` cannot express a per-event decode of Seaport's offer/consideration arrays anyway), so `recipe.source` names the endpoint and the exact call sequence.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 26489239130434782 wei** (sum 1218505000000000000 wei over 46 qualifying fills). How it was computed, over exactly blocks 26019451–26026607: 1. Confirmed `eth_chainId` = 1 and the pinned closing hash `0x8a84f5aa…cdec2` on `ethereum-rpc.publicnode.com` and, independently, on `eth-mainnet.nodereal.io`. 2. `scan.mjs` over the window for the collection's `Transfer` topic: 28 ERC-721 transfers in 26 distinct blocks. A qualifying Seaport fill must move the token, so only those blocks can hold one. 3. Fetched `OrderFulfilled` logs (topic0 `0x9d9af8e3…6f31`) from Seaport 1.5 and 1.6 in those 26 blocks — 214 events — and ABI-decoded the offer/consideration arrays in-process, applying the brief's sale and price rules: 168 held no Akutars item, none were multi-NFT or non-ETH/WETH, 46 qualified (21 listing fills, 25 bid fills, all on Seaport 1.6). Both endpoints reproduced the identical sum. One judgment call, stated under `definitions` and in `notes`: 21 of the 46 events are matched pairs — the same token id in one transaction fires the taker's bid-side event (gross) and the maker's listing-side event (the seller's 99% leg). The brief defines a sale as an `OrderFulfilled` event and gives a price rule for each side, so both are counted, with no deduplication. The alternative (one row per transaction+token id at the gross price: 25 trades, mean 39652000000000000 wei) is recorded in `notes` for legibility but is not the answer. The recipe is `{ kind: "panel", source: "https://ethereum-rpc.publicnode.com" }` — the brief sets `"evidence": "panel"`, and `check-answer.mjs` rejects any chain recipe for such a brief; none of the chain kinds could decode Seaport's dynamic item arrays anyway.

The check passes. The deliverable is complete. **Answer: 26489239130434782 wei** (≈0.0265 ETH) — the average Akutar sale price on OpenSea over the pinned window, written to `artifacts/answer.json` and left untracked for the daemon to upload. How it was computed: - **Pin confirmed twice.** Block 26026607's hash matched the brief's pin on `ethereum-rpc.publicnode.com` (the scan endpoint) and, as a one-call cross-check, on `rpc.mevblocker.io/fast` — two independent operators, both reporting chainId 1. - **One whole scan.** The stock scan script can't decode Seaport's nested offer/consideration arrays, so I wrote a small Node 22 decoder in `test/scratch/avg.mjs` (no dependencies, prints only totals). It fetched all 12,231 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over blocks 26019451–26026607 in one pass with no refused chunks, and applied the brief's definitions in-process. - **46 qualifying sales**: exactly one NFT item across offer + consideration, that item being itemType 2 of the Akutars contract. 21 were listing fills (price = sum of all consideration amounts, accepted only when every consideration item was ETH or WETH) and 25 were bid fills (price = the single ETH/WETH offer amount). Sum 1218505000000000000 wei; floor(sum / 46) = 26489239130434782, which clears the `min: "1"` guard. - **Answer shape.** Since the brief says `"evidence": "panel"`, the recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}`. The window object was copied with the brief's exact key order (the checker compares stringified JSON), and the choices the brief left open — one sale per event even within a matchOrders transaction, itemType 0 as native ETH regardless of token field, itemTypes 3/4/5 counted as NFTs for the exclusion test — are stated under `definitions`. `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs` prints `ok`.

Created `artifacts/answer.json` with the computed uint256 answer: `26489239130434782` Verification passed: ```text node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json ok ``` I also cross-checked the aggregate scan on two public RPC endpoints; both returned 46 qualifying sales and the same total/average.

I wrote `artifacts/answer.json` with an average Akutars sale price of **26489239130434782 wei** (about 0.0265 ETH), and the answer checker prints `ok`. - **Scan:** I fetched every OrderFulfilled event from both Seaport contracts over exactly blocks 26019451–26026607, using `https://ethereum-rpc.publicnode.com` (12,231 events). A small Node script in `test/scratch/` decoded the offer and consideration items. I did not use the provided `scan.mjs` for the scan itself, because it can only sum or rank raw log fields and can't decode Seaport's item arrays. - **Checks:** The chain id is 1. The closing block's hash matches the pinned hash on both publicnode and `rpc.mevblocker.io`. - **Result:** 46 events involved the collection, and all 46 qualified: none were bundles, ERC-1155 fills or paid in another token. Their prices add up to 1218505000000000000 wei, which is in the file as `figure`; divided by 46 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` names the endpoint, both Seaport addresses, the event topic and the block range. **Decision for you:** Most sales in this window are accepted collection offers, and each of those trades emits two qualifying events. One is the buyer's order, for example 0.0075 WETH; the other is the seller's side, 0.007425 WETH after the 1% fee. The brief defines a sale as one event, so I counted both, as it says, and noted this in the file. If one trade should count once, the average would come out different and the answer would need recomputing.

Done. `artifacts/answer.json` is written, untracked (excluded via `.git/info/exclude`), and `check-answer.mjs` prints `ok`. ## Answer **26489239130434782 wei** (~0.0265 ETH) — the floored mean over 46 qualifying sales, sum 1,218,505,000,000,000,000 wei. ## How it was computed - **Pin confirmed** on two operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`): chain id 1, block 26026607 hash `0x8a84f5aa…cdec2`. - **Scan**: `eth_getLogs` for the `OrderFulfilled` topic on both Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607. 12,231 logs, no chunk refused. I reran on the second operator with smaller chunks as a truncation guard — identical totals. - **Decode/filter** per the brief's definitions: exactly one NFT-type item across offer+consideration, it must be itemType 2 of the Akutars contract, exactly one offer item; listing fills priced as the sum of an all-ETH/WETH consideration, bid fills as the ETH/WETH offer amount. 46 events qualify (21 listings, 25 bids, all on Seaport 1.6). - **Recipe** is `panel` with the RPC URL as `source`, since the brief is `"evidence": "panel"` and the check script refuses any chain recipe for it. ## One thing to flag 21 of the 24 transactions are OpenSea WETH-bid acceptances via `matchOrders`, which emits **two** qualifying events for the same token: the bid (fee-inclusive amount) and the taker's mirror listing (99% of it). The brief defines a sale as *an event* and gives price rules for both fill directions, so I counted both — that's the literal reading and the one the task says to follow. I recorded the alternative in `definitions.matched-orders` and `notes`: de-duplicating to one sale per (tx, token) gives 25 sales and an average of 39652000000000000 wei. If the panel splits, that ambiguity is the likely reason.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. - **Answer:** 26489239130434782 wei, the average sale price rounded down. - **Basis:** 46 qualifying sales summing to 1218505000000000000 wei. - **Scan:** I scanned 12,231 Seaport 1.5 and 1.6 `OrderFulfilled` logs over exactly blocks 26019451 to 26026607. The RPC was `https://ethereum-rpc.publicnode.com`, which returned chain id 1 and the pinned closing block hash. I did not check the hash on a second operator's endpoint. - **Decoding:** The provided `scan.mjs` can't decode the offer and consideration arrays, so I decoded them with my own script in `test/scratch/s.mjs`. That script isn't part of the submission, so the recipe can't be reproduced by running it. - **Recipe kind:** The brief says `"evidence": "panel"`, and the checker requires a `panel` recipe for that. The recipe's `source` is a text description of the RPC, contracts, topic and block range, not a URL, and the checker accepted it. The checker rejected the `window` object until its keys were in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`), so I matched that order.

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok` (exit 0); the file is untracked and not force-added. ## What I computed **Answer: `26489239130434782` wei** (~0.0265 ETH) — sum `1218505000000000000` wei over 46 qualifying sales, floor-divided. Method (script in `test/scratch/akutars.mjs`, Node 22, no deps — `scan.mjs` can't decode `OrderFulfilled`'s dynamic tuple arrays): 1. `eth_getLogs` for `Transfer` on `0xaad3…1fa9` over exactly 26019451–26026607 → 28 transfers in 26 distinct blocks. Any Seaport fill of the collection must move a token, so those blocks are a complete superset. 2. `eth_getLogs` for `OrderFulfilled` on Seaport 1.5 + 1.6, one call per those 26 blocks → 214 events. 3. Decoded each and applied the brief's definitions → 46 qualifying sales (21 listing-side, 25 bid-side). Zero Akutars events were dropped for a bundle, a non-ETH/WETH payment, or an unexpected offer shape, so the answer doesn't hinge on those edge rules. ## The one real judgment call 21 of the 46 events are **mirror pairs**: a single tx emits both the bid order (offer = WETH, price = offer amount) and the seller's mirror order (offer = the NFT, price = consideration sum, ≈99% of the bid). Economically that's one trade, but the brief defines a sale *per `OrderFulfilled` event* and defines a price for each of the two shapes, so both legs count. Any dedup would require a rule the brief doesn't state. I recorded the alternative under `definitions.mirrored_fills` and in `notes`: collapsing each pair to its bid leg gives 25 trades and `39652000000000000` wei. This is the most likely place the panel splits. ## Recipe The brief sets `"evidence": "panel"`, and `check-answer.mjs` requires a `panel` recipe for a panel brief — so the recipe is `{kind: "panel", source: "https://rpc.mevblocker.io/fast"}` with the full method written out in `notes`. Worth flagging: no catalogue recipe can express this computation (`log-sum` only adds a fixed 32-byte data word), which I state in `notes`. ## Verification Pin `0x8a84f5aa…cdec2` confirmed on both endpoints. `https://rpc.mevblocker.io/fast` and `https://ethereum-rpc.publicnode.com` (different operators) returned identical count, sum, and closing hash. Flashbots was dropped after repeated 429s; dRPC caps free ranges at 10000 blocks.

Created [artifacts/answer.json](artifacts/answer.json) with the reproducible calculation. Average: **26,489,239,130,434,782 wei** across **46 sales**. The supplied validator prints `ok`; replaying the embedded procedure against the fetched logs reproduces the answer.

I have the full picture. This is a chain question with `"evidence": "panel"` in the brief — so the check script will require a `{"kind": "panel", "source": <url>}` recipe, but the answer itself must be computed on-chain per the definitions. Let me check the environment, then build the scan.Now I'll write a scratch script that scans `OrderFulfilled` logs on both Seaport contracts over the pinned window, decodes offer/consideration items, applies the sale/price definitions, and prints only the totals.Scan completed on the first endpoint — 12,231 `OrderFulfilled` logs, 46 qualifying Akutars sales, avg ≈ 0.02649 ETH. Since this is a panel-evidence question (nothing gets rerun by the deployer — panel agreement is the evidence), a truncation cross-check on a second operator is cheap insurance. Let me verify on mevblocker.Both operators agree exactly. Let me do a quick sanity check on the price distribution (min/max, listing vs bid split) to rule out decode errors.All three endpoints (Flashbots, mevblocker, publicnode) agree exactly: 12,231 `OrderFulfilled` logs → 46 qualifying Akutars sales (21 listings, 25 bids), no zero-price or foreign-token fills, sum 1,218,505,000,000,000,000 wei → average **26,489,239,130,434,782 wei**. Writing the answer file now.Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: `26489239130434782` wei (~0.02649 ETH)** How it was computed: - Scanned `OrderFulfilled` (topic0 `0x9d9af8e38d66c62e2c12f0225249fd9d721c54b83f48d9352c97c6cacdcb6f31`) on Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607, with `eth_chainId` and the pinned closing hash confirmed on each endpoint. - 12,231 `OrderFulfilled` logs decoded; 46 fills qualified (exactly one NFT item total, itemType 2, Akutars `0xaad35c2dadbe77f97301617d82e661776c891fa9`): 21 listing fills priced as summed ETH/WETH consideration, 25 bid fills priced as the single ETH/WETH offer amount. No exclusions for foreign-token payment and no zero-price fills. - Sum = 1,218,505,000,000,000,000 wei → floor-mean = 26,489,239,130,434,782 wei. - Reproduced identically on three independent operators: `rpc.flashbots.net/fast`, `rpc.mevblocker.io/fast`, `ethereum-rpc.publicnode.com`. The recipe is `{"kind": "panel", "source": "https://rpc.flashbots.net/fast"}` because the brief declares `"evidence": "panel"` — the checker requires that kind regardless of the on-chain nature of the computation, which is documented in `notes` along with the endpoints used.

Created `artifacts/answer.json` with the reproduction procedure. Average: **26,489,239,130,434,782 wei** across **46 qualifying sales**. The required checker printed `ok`.

**26489239130434782 wei** — mean of 46 qualifying Seaport OrderFulfilled fills (sum 1218505000000000000 wei) over blocks 26019451–26026607, pin hash confirmed on three endpoints. `check-answer.mjs` prints `ok` for `artifacts/answer.json`.

Created `artifacts/answer.json` with **26489239130434782 wei**, averaged over 46 qualifying sales, and reproducible RPC code. The supplied checker printed `ok`; the reproduction code matched the fetched logs.
