I'll start by reading the oracle request and the skill files.Now let me read the scan and check scripts.Now let me check the environment and the rest of the inputs.Node 22 is ready. First, let me verify the chain and pinned block hash on a public endpoint.The hex was wrong. Let me compute it properly.Pin confirmed: chain 1, block hash matches. Now let me get the OrderFulfilled topic0 and write a scratch scanner that decodes the logs per the definitions.That's the known Seaport OrderFulfilled topic. Now I'll write a scratch scanner that fetches logs chunked (halving on refusal) and decodes them per the definitions.Now let me run the scan against publicnode.Scan completed cleanly — no refusals, 12,231 logs total, 36 qualifying sales, all on Seaport 1.6. Average = 1,622,217,777,777,777 wei. Before writing the answer, let me sanity-check: (a) verify total log count on a second endpoint to rule out silent truncation, (b) inspect the qualifying sales and near-misses (criteria items, bundles) to confirm the decode.All 36 qualifying sales are clean single-NFT listing fills — no criteria items, bundles, or other-token payments involving the collection. Now a quick cross-check of the log count on a second endpoint from a different operator to rule out silent truncation.Both endpoints agree: 12,231 logs, 36 qualifying sales, sum 58,399,840,000,000,000 wei, floor-average **1,622,217,777,777,777 wei**. The pin matched on both. Since the brief has `"evidence": "panel"`, the recipe must be `panel` with a source URL — I'll name the RPC endpoint the computation ran against.Check passes. Let me remove the stray `scan-err.log` I left in the repo root — only `artifacts/answer.json` may be created outside `test/scratch`.Done. `check-answer.mjs` prints `ok`. **Answer: 1,622,217,777,777,777 wei** (~0.00162 ETH) — the average MONSTER MOBS sale price over blocks 26019451–26026607. How it was computed: - Fetched all `OrderFulfilled` logs (topic `0x9d9af8e3…b6f31`) from Seaport 1.5 and 1.6 over exactly the pinned window, in 500-block chunks with halving on refusal — 12,231 logs total, no chunk refusals or truncation. - Decoded offer/consideration items per the pinned definitions: exactly one NFT-type item, itemType 2, token = `0x125ecab9fdc132cad4d6c055b9381aad60efaf3d`. - **36 qualifying sales**, all single-NFT listing fills paid in ETH/WETH (no criteria items, bundles, or other-token fills involving the collection occurred). Sum = 58,399,840,000,000,000 wei ÷ 36 = floor → 1,622,217,777,777,777. - Cross-checked on a second operator's endpoint (nodereal): identical log count, sale count, and sum. Closing-block hash matched the pin on both endpoints. `artifacts/answer.json` carries the copied request id/window, a `panel` recipe (required by the brief's `"evidence": "panel"`), the open definitions as applied, and the method in `notes`.

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **The answer: 1,622,217,777,777,777 wei** (~0.00162 ETH) average sale price for MONSTER MOBS over the pinned window. How it was computed: - Fetched every `OrderFulfilled` log (topic `0x9d9af8…6f31`) from both pinned Seaport contracts (1.5 and 1.6) over exactly blocks 26019451–26026607, using a scratch Node decoder in `test/scratch/avg.mjs` — the delivered `scan.mjs` can't decode the event's dynamic `offer`/`consideration` arrays, so I decoded them per the Seaport ABI in-process and printed only totals. - Of 12,231 OrderFulfilled events in the window, 36 qualified under the pinned definitions: all were listing fills of exactly one ERC-721 of the collection with every consideration item in native ETH or WETH. There were no bid fills, no fills rejected for another payment token, and no zero-price fills. - Sum of prices, fees included: 58,399,840,000,000,000 wei; average = floor(sum / 36) = 1,622,217,777,777,777. - Because this is panel evidence (nothing is rerun — the panel's agreement is the evidence), I guarded against silent log truncation by scanning twice from independent operators with different chunk sizes: `rpc.flashbots.net/fast` and `ethereum-rpc.publicnode.com` returned identical log counts, sale counts, and sums, and both confirmed chain id 1 and the pinned closing hash. The answer file copies the request id, chain, and window verbatim from the brief (including its key order, which the checker compares serialized), uses the `panel` recipe with the RPC source as required for a panel-evidence brief, and states every resolved choice under `definitions` (single-offer-item reading of listing/bid fills, ERC-1155 exclusion, no zone filter, zero-price handling). The file is untracked, as required — the daemon uploads it itself.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` on it. The average sale price of MONSTER MOBS over blocks 26019451–26026607 is **1622217777777777 wei**. - **Result:** 36 qualifying sales sum to 58399840000000000 wei, and 58399840000000000 / 36 = 1622217777777777.77, rounded down. All 36 were listing fills; none were bid fills, and none were excluded by payment token or bundling. - **Method:** the provided scan script can't decode Seaport events, so I wrote a one-off script in `test/scratch/`, which isn't submitted. I fetched the collection's Transfer logs over the exact window (48 transfers in 43 transactions). I then decoded every Seaport 1.5 and 1.6 `OrderFulfilled` log in those transactions' receipts and applied the definitions in `oracle.json`. - **Endpoint:** I read from `https://ethereum-rpc.publicnode.com` only. It reported chain id 1, and the closing block hash matched the pin. I did not check a second endpoint. - **Recipe kind:** `oracle.json` sets `"evidence": "panel"`, so the checker only accepts a `panel` recipe with a source URL. I gave the RPC endpoint as the source and described the method in `notes`. The deployer therefore can't rerun this as a chain recipe, and agreement depends on the panel landing on the same value.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It gives an average sale price of **1622217777777777 wei** for MONSTER MOBS over blocks 26019451 to 26026607. - **Scan:** I pulled every `OrderFulfilled` log from Seaport 1.5 and 1.6 over the pinned range from `https://ethereum-rpc.publicnode.com`. That was 12,231 logs with no duplicates. The chain id and the closing block hash matched the pin on that endpoint. I did not check the hash on a second endpoint. - **Sales:** 36 events qualified under the definitions, all listing fills paid in ETH. None were excluded for other tokens or unusual shapes. The total is 58399840000000000 wei, and dividing by 36 and rounding down gives the answer. - **Recipe:** the brief says `"evidence": "panel"`, so the recipe kind is `panel`, with the RPC endpoint and the event topic as its `source`. The stock `scan.mjs` can't decode Seaport offer and consideration arrays, so I used a throwaway decoder in `test/scratch/`. It isn't part of the submission. - **Why the last attempt failed:** its log showed `runtime_error` and "Not logged in". I didn't investigate further. Nothing in this run needed a login. `artifacts/answer.json` is the only file added, and it is untracked.

Wrote [artifacts/answer.json](artifacts/answer.json) with **1,622,217,777,777,777 wei**, averaged over 36 qualifying sales, and a reproduction script. Computation checks passed; the required validator printed `ok`.

Created [artifacts/answer.json](artifacts/answer.json) with the answer **1,622,217,777,777,777 wei**, computed across 36 qualifying sales, and a reproducible RPC procedure. The required validator prints `ok`.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The answer is **1622217777777777** wei, the average sale price of MONSTER MOBS over blocks 26019451 to 26026607. - **Sales:** 36 qualified. All 36 were listing fills, and none were bid fills or fills paid in another token. - **Sum:** the prices add up to 58399840000000000 wei. I put that in `figure`, and the average is that sum divided by 36, rounded down. - **Scan:** I read every Seaport 1.5 and 1.6 `OrderFulfilled` log over exactly the pinned blocks, 12231 in all. I decoded the offer and consideration items myself and applied the definitions in the brief. - **Endpoint:** I used only `https://ethereum-rpc.publicnode.com`. It reported chain 1, and the hash of block 26026607 matched the pin. I did not check the hash on a second endpoint, which the reference suggests as a cheap extra. - **Recipe:** the brief is a panel-evidence question, so the recipe is `panel`, with the RPC endpoint and event topic as its source. The deployer will not rerun it, so the panel's agreement on 1622217777777777 is what counts. - **Scanner:** the bundled `scan.mjs` can't decode Seaport's offer and consideration arrays, so I wrote my own scanner at `test/scratch/sales.mjs`. It is not submitted, and the notes in the answer describe what it did. The checker also rejected my first draft for writing the window keys in a different order from the brief, so I reordered them to match.

Done. **Answer: `1622217777777777` wei** (≈0.001622 ETH), written to `artifacts/answer.json` (untracked; `.gitignore` already excludes `artifacts/`). How it was derived: - **Pin confirmed** on three independent operators (publicnode, mevblocker, drpc): block 26026607 hash matches `0x8a84f5aa…cdec2`, chain id 1. - **Literal scan**: `eth_getLogs` for the `OrderFulfilled` topic on Seaport 1.5 + 1.6 over exactly 26019451–26026607, 200-block chunks with halving on refusal, deduped by (block, logIndex) → 12,231 logs, decoded with the Seaport ABI (`SpentItem[]` / `ReceivedItem[]`). - **36 qualifying sales** of `0x125ecab9…af3d`, all listing fills paid entirely in ETH/WETH, fees included. Sum `58399840000000000` wei, range 0.00144999–0.002 ETH. 58399840000000000 ÷ 36 = 1622217777777777.77… → floored. - **Run twice by two routes on two operators** (a Transfer-prefiltered pass on publicnode, then the full literal window on mevblocker); identical count, sum and average. The brief sets `"evidence": "panel"`, so the recipe is `{kind: "panel", source}` — the checker rejects any chain recipe here, and no catalogue chain recipe could express this anyway (`log-sum` sums one fixed data word; a Seaport price is a sum over a decoded variable-length consideration array). `notes` carries the exact query and decoding so a rerun lands on the same number. Every choice the brief left open is under `definitions` — single-offer-item shape, WETH counted 1:1, no zone/conduit filter, floor rounding, one sale per log. None of them moved the figure: there were no bid fills, no other-token fills, no bundles and no mixed offers in the window. `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` prints `ok` (exit 0); file is 5,431 bytes.

The average MONSTER MOBS sale price over the pinned window was **1622217777777777 wei** (about 0.00162 ETH), from 36 qualifying sales. The answer is in `artifacts/answer.json`, and the checker (`check-answer.mjs`) prints `ok` for it. **How it was computed** - I wrote a small Node script in `test/scratch/`. The provided `scan.mjs` can only count and sum raw log words; it can't decode Seaport's item arrays. - The script fetched the `OrderFulfilled` events from both Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607. It read 500 blocks at a time and split a range in half whenever the endpoint refused it. The data came from `https://ethereum-rpc.publicnode.com`. - On that endpoint, the chain id was 1 and the hash of block 26026607 matched the pinned one. I also confirmed the pinned hash on `https://eth.drpc.org`, a different operator. - The window held 12,231 `OrderFulfilled` events. 36 of them involved this collection, and all 36 qualified. - Every one of the 36 was a listing fill: one ERC-721 token offered, with every payment item in native ETH. There were no WETH payments, no bid fills, no bundles and no ERC-1155 fills. - The prices include fees and range from 0.00144999 to 0.002 ETH. They sum to 58399840000000000 wei (the `figure` field), and that total divided by 36, rounded down, gives the answer. **Choices recorded in the file** - **Recipe type:** the request is marked as panel evidence, so the recipe is a `panel` one. Its `source` names the endpoint, both Seaport addresses, the event signature and the block range. - **Two rules the request left open,** both written under `definitions`: - Any item of types 2–5 counts as an NFT when checking for "no other NFT". - An event whose offer has more than one item is neither a listing nor a bid fill, so it is excluded. - **Counting:** each event counts as its own sale. Some transactions filled several tokens at once; each of those was a separate event with its own token. I ran one full scan and didn't run a second. As instructed, `artifacts/answer.json` is left untracked and not committed.

Wrote `artifacts/answer.json` with the reproduction script. Average: **1,622,217,777,777,777 wei** across **36 sales**. Required validator printed `ok`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **1622217777777777 wei**, about 0.001622 ETH. - **Sales counted:** 36 qualifying sales, all listing fills, with no bids. The prices sum to 58399840000000000 wei, and 58399840000000000 / 36 = 1622217777777777.77, rounded down. - **Exclusions:** none were needed for bundles, other NFTs or other payment tokens. A further 4 Seaport events held no NFT at all, and 12,191 belonged to other collections. - **Scan:** I read the OrderFulfilled events from both Seaport contracts over exactly blocks 26019451 to 26026607, through one endpoint (`ethereum-rpc.publicnode.com`), in one pass with no refused ranges. That was 12,231 logs. - **Pin:** the chain id and the closing hash match the pin on three operators (publicnode, flashbots and merkle). - **Decoder:** `scan.mjs` can't decode Seaport's nested item arrays, so I wrote a small decoder in `test/scratch/`. It isn't submitted. - **Cross-check:** every transaction that has both a collection `Transfer` and a Seaport fill is one of my sale transactions. That is 31 transactions holding the 36 sales, since some transactions contain several fills. No sale was missed or counted without a transfer. The brief says `evidence: "panel"`, and the checker only accepts a `panel` recipe for that. The recipe is therefore `{kind: "panel", source: <the RPC URL and log query>}`. The definitions and the exact method are in `definitions` and `notes`. `artifacts/answer.json` is untracked and not committed, and `test/scratch/` holds only scaffolding.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It reports an average sale price of **1622217777777777 wei** across 36 qualifying sales, which sum to 58399840000000000 wei. - **Method:** I fetched the collection's ERC-721 Transfer logs over blocks 26019451–26026607. That gave 48 logs in 43 blocks. I then fetched Seaport 1.5 and 1.6 `OrderFulfilled` logs in exactly those blocks (142 logs) and decoded them with the Seaport ABI. - **Coverage:** A sale must move the token, so restricting to Transfer blocks should not miss any sale. I did not run a full unfiltered `OrderFulfilled` scan to confirm that. - **Exclusions:** None of the 142 logs were excluded by the bundle or other-token rules. The Transfer logs that were not sales, such as mints, contribute no `OrderFulfilled` price. - **Recipe kind:** The brief says `"evidence": "panel"`, so the recipe is `kind: "panel"` with the RPC and log query as its source. Nothing gets rerun from it. - **Endpoints and pin:** Logs came from `https://ethereum-rpc.publicnode.com`. I confirmed chain id 1 and the pinned closing hash on it and on `https://rpc.flashbots.net/fast`. - **Custom script:** I used my own script in `test/scratch/run.mjs` rather than `scan.mjs`, because `scan.mjs` cannot decode the array fields in `OrderFulfilled`. It is not part of the submission.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average sale price over blocks 26019451 to 26026607 is **1622217777777777 wei**. - **Sales counted:** 36 qualifying Seaport 1.5/1.6 fills. Their prices sum to 58399840000000000 wei, and the mean is 1622217777777777.77 wei, rounded down. - **Exclusions:** No fill was excluded as a bundle, an ERC-1155 fill or a payment in another token. - **Pin:** `eth_chainId` and the closing block hash matched on two endpoints, `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`. - **Method:** I did not pull every Seaport log. I fetched the collection's Transfer logs (48 transfers in 43 transactions), then decoded every `OrderFulfilled` log in those transactions' receipts. Every fill of the collection moves an NFT, so this should catch all of them. The script is in `test/scratch/run.mjs`, which is not delivered. - **Recipe kind:** The brief says `"evidence": "panel"`, and the checker requires `{kind: "panel", source}` for that. So the recipe is a `panel` recipe with a `source` string describing the RPC calls and decoding, not a rerunnable `log-sum`. The full method is in `notes`. I did not use `scan.mjs` for the figure, because it can't decode Seaport's nested event data. I only imported its keccak function.

The checker prints `ok`, and `git status` is clean apart from the untracked `artifacts/` and `test/scratch/` (nothing staged or committed, as required). ## Result **Average sale price: `1622217777777777` wei** (~0.001622 ETH) **How it was computed** (`test/scratch/avg.mjs`, a Node 22 script reusing the bundled `keccak256`, printing totals only): 1. Confirmed chain id 1 and the pinned closing hash `0x8a84f5aa…cdec2` at block 26026607 on two operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`). 2. `eth_getLogs` over exactly blocks 26019451–26026607 for `OrderFulfilled` (topic0 `0x9d9af8e3…6f31`) on both Seaport 1.5 and 1.6, chunked with halving on refusal and deduped by `blockNumber:logIndex`. 3. Decoded the `SpentItem[] offer` / `ReceivedItem[] consideration` arrays and applied the brief's definitions verbatim. **Totals:** | | | |---|---| | OrderFulfilled logs in window | 12,231 | | Logs with exactly one ERC-721 of the collection and no other NFT | 36 | | Listing fills paid entirely in ETH/WETH | 36 (all on Seaport 1.6) | | Bid fills / excluded for other token or shape | 0 / 0 | | Sum of prices (fees included) | 58,399,840,000,000,000 wei | | min / max | 0.00144999 / 0.002 ETH | | floor(sum / 36) | **1,622,217,777,777,777 wei** | The second operator, scanned with smaller chunks, returned identical counts and sums, so no endpoint truncated. **Assumptions stated under `definitions`:** "no other NFT" means no other item with `itemType >= 2` anywhere in offer or consideration; each OrderFulfilled log is one sale (no per-transaction dedup, per the brief's own definition); WETH counts 1:1 with ETH. Since the brief is `evidence: "panel"`, the recipe is `{ kind: "panel", source: <RPC + exact filter> }` — the catalogue's `log-sum` cannot express a price that lives inside dynamic ABI arrays, so the exact filter and decoding rules are spelled out in `definitions`/`notes` for the rerun.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price is **1622217777777777 wei**. - **Sales counted:** 36 qualifying sales with a combined price of 58399840000000000 wei, giving that mean rounded down. - **Scan:** I pulled all 12231 `OrderFulfilled` logs from both Seaport contracts over exactly blocks 26019451 to 26026607. I read them from `https://ethereum-rpc.publicnode.com`, which returned chain id 1 and the pinned closing block hash. - **Filtering:** I decoded each event's offer and consideration items with a small script of my own (in `test/scratch/`, not submitted), since the provided scan script only sums single fields. I then applied the request's definitions as stated. - **Recipe kind:** The brief is marked `evidence: panel`, so `panel` was the only recipe kind the check would accept. A panel recipe can't be rerun the way a chain recipe can. So the log source, both contracts, the event topic and the block range are spelled out in the recipe's `source` field. - **Not done:** I did not check the closing block hash on a second operator's endpoint.

Created [artifacts/answer.json](artifacts/answer.json). Average: **1,622,217,777,777,777 wei** across 36 qualifying sales. Includes reproduction steps; the required checker printed `ok`.

Created `artifacts/answer.json` with the average **1,622,217,777,777,777 wei** across 36 qualifying sales and reproduction code. The required validator printed `ok`.

The average MONSTER MOBS sale price over blocks 26019451–26026607 was **1622217777777777 wei** (about 0.00162 ETH), and the answer is written to `artifacts/answer.json`. The answer check prints `ok`. - **Sales:** I pulled every Seaport OrderFulfilled event from both the 1.5 and 1.6 contracts over exactly the pinned blocks, 12,231 in total. 36 of them qualified as sales of this collection. - **Sale type:** all 36 were someone buying a listed token outright, paid in ETH or WETH; none were accepted bids. No event involving the collection was excluded: there were no bundles, no ERC-1155 tokens and no other payment tokens. - **Price:** the prices, fees included, add up to 58399840000000000 wei. Divided by 36 and rounded down, that gives the answer. Individual sales ran from 0.00145 to 0.002 ETH. - **Multi-sale transactions:** two transactions each bought several single-token listings. I counted each event as its own sale, as the definitions say. - **Block check:** the closing block hash matched the pinned one on two separate providers, publicnode and flashbots. The recipe can't be one of the rerunnable on-chain kinds. The request marks this as a panel question, so the checker only accepts a `panel` recipe that names its source. The source I gave is the eth_getLogs query, and `notes` describes how I decoded it. The provided scan script can only sum simple event fields, so I wrote my own decoder in `test/scratch/` instead. That folder is deleted before submission, so the script isn't part of what gets delivered. The requester's definitions are copied into `definitions` and applied as written.

check-answer.mjs reports `ok`. `artifacts/answer.json` is written: average sale price of MONSTER MOBS on OpenSea over the pinned window is **1,622,217,777,777,777 wei** (≈0.00162 ETH), from 36 qualifying Seaport OrderFulfilled sales (sum 58,399,840,000,000,000 wei), cross-checked identically on two independent public RPC operators against the pinned block hash. Since the brief's `evidence` is `"panel"`, the recipe is `panel` with a `source` documenting the exact `eth_getLogs`/decode procedure to reproduce it.

How it was computed: - Pulled all `OrderFulfilled` logs (topic `0x9d9af8e3…`) from Seaport 1.5 and 1.6 over blocks 26019451–26026607 in 256-block chunks with halving on refusal — 12,231 events, no chunk near a provider cap. - ABI-decoded each log's `SpentItem[] offer` / `ReceivedItem[] consideration` (the catalogue's `scan.mjs` only sums flat data words, so it can't reach inside those tuple arrays; a scratch decoder did that, and `scan.mjs --keccak` produced the topic). - 36 events named the collection and **all 36 qualified** — no bundles, no ERC-1155, no non-ETH/WETH payment, all listing fills. Sum 58399840000000000 wei / 36 → floor 1622217777777777. Verification: - `eth_chainId` = 0x1 and the pinned closing hash confirmed on two operators (publicnode, mevblocker). - Independent path from the other direction on a second operator: all 48 ERC-721 `Transfer` logs of the collection in the window → Seaport logs in those blocks, intersected by tx hash → exactly the same 36 events, block for block. So the range wasn't silently truncated. Two notes on judgment calls, both recorded under `definitions`: - The brief sets `"evidence": "panel"`, so the recipe is `{kind: "panel", source}` — `check-answer.mjs` rejects a chain recipe here. The figure is still pure chain data, reproducible from any archive endpoint. - The brief defines a sale at the *event* level, so I counted events, not trades. I checked that matters nothing here: every qualifying event was in its own transaction with a distinct token id, so no matched-order pair double-counted.

I wrote `artifacts/answer.json` with an average sale price of **1622217777777777 wei**. `check-answer.mjs` prints `ok`. - **Sales counted:** 36 qualifying Seaport 1.5 and 1.6 sales of MONSTER MOBS over blocks 26019451 to 26026607, totalling 58399840000000000 wei. None were dropped for being paid in another token. - **Method:** I used a custom script, `test/scratch/s.mjs`, instead of the provided `scan.mjs`. It first pulled the collection's Transfer logs (48 logs in 43 blocks), then decoded the Seaport `OrderFulfilled` logs only in those blocks. Sales are matched by transfer blocks, so I did not scan every Seaport log in the window. - **Endpoint:** I used only `https://ethereum-rpc.publicnode.com` and confirmed the closing block hash on it. I did not check the hash on a second operator's endpoint. - **Recipe kind:** The brief says `"evidence": "panel"`, and the catalogue allows only the `panel` recipe in that case. The recipe is therefore `panel` with that RPC URL as its source. The deployer cannot rerun it as an on-chain recipe, and the notes describe how I computed the figure.

Done. `artifacts/answer.json` is written, untracked, and `check-answer.mjs` prints `ok`. **Answer: 1622217777777777 wei** (≈0.0016222 ETH), from 36 qualifying sales summing to 58399840000000000 wei. How it was computed, over exactly blocks 26019451–26026607: - **Pass 1 (the definition itself):** `eth_getLogs` for topic0 `0x9d9af8e3…` on Seaport 1.5 + 1.6, 400-block chunks with halving on refusal, via `https://ethereum-rpc.publicnode.com` — 12,231 `OrderFulfilled` logs. Each was ABI-decoded (`SpentItem[] offer`, `ReceivedItem[] consideration`) and classified: 36 MONSTER MOBS sales; rejects were 11,750 other-collection fills, 436 ERC-1155, 5 multi-NFT bundles, 4 with no NFT item. All 36 were listing fills paid entirely in ETH/WETH on Seaport 1.6, prices 0.00144999–0.002 ETH including fees. - **Pass 2 (independent path):** collection ERC-721 `Transfer` logs → 48 transfers in 43 txs → receipts → same decode. Identical 36 sales and identical sum. It also shows nothing touching the collection was dropped for shape: every Seaport log in those txs qualified. - **Pins:** `eth_chainId` `0x1` and closing hash `0x8a84f5aa…cdec2` confirmed on publicnode and, from a second operator, `https://eth.drpc.org`. The collection's `name()` at the closing block returns `MONSTER MOBS`. Two things worth flagging, both stated in `definitions`/`notes`: - The brief sets `"evidence": "panel"`, and the checker rejects any non-`panel` recipe for such a brief — so the recipe is `{kind: "panel", source}` with the source naming the exact `eth_getLogs` read. No chain recipe in the catalogue could express this anyway: it needs decoding of two dynamic struct arrays plus a per-event shape test and a mean, which `log-sum`/`log-rank` cannot do. The delivered `scan.mjs` likewise can't decode Seaport items, so the decode ran in my own script under `test/scratch/`; `scan.mjs` was used for the topic0 keccak and the `name()` call. - The brief leaves open whether both sides of a matched pair count twice. I count each qualifying `OrderFulfilled` log once, as written; no two qualifying logs shared a transaction and token id here, so the choice doesn't move the figure.
