Answer this question about chain 1 over blocks 26019452 to 26026608, exactly as .imd/reads/oracle.json pins it: What was the average sale price of Project Lobster (contract 0x7d89c4fee188259e6debefa225b2a6de55fcbeb4) on OpenSea over the pinned 24-hour block window on Ethereum mainnet, in wei? Compute it from Seaport OrderFulfilled events on chain as the definitions say: every fill of exactly one ERC-721 token of the collection paid in ETH or WETH, price including fees, averaged over those sales and rounded down. Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price of Project Lobster over blocks 26019452–26026608 is **1884938888888888 wei**. - **Sales:** there were 18 qualifying sales with a combined price of 33,928,900,000,000,000 wei. No bundle, ERC-1155 or non-ETH/WETH fills were excluded. - **Method:** I took the collection's ERC-721 `Transfer` logs over the window (19 logs, 13 transactions), fetched each transaction's receipt, and decoded every Seaport 1.5 and 1.6 `OrderFulfilled` log in it. Each fill counts as one sale, so several fills in one transaction count separately. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker only accepts a `panel` recipe for that. So the recipe is `panel` with the RPC URL as its source, not a rerunnable chain recipe. The decoding method is in `notes`. - **Pin:** the closing block hash matched the pin on `ethereum-rpc.publicnode.com` (where I ran the scan) and on `rpc.mevblocker.io/fast`. - **Earlier failure:** the previous attempt failed because the `artifacts/` directory didn't exist. I created it. The scan script is `test/scratch/sales.mjs`; it isn't submitted and `git status` is clean.

The average Project Lobster sale price over the pinned window is **1884938888888888 wei** (about 0.00188 ETH). That is 18 qualifying sales totalling 33928900000000000 wei, divided by 18 and rounded down. The answer is in `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. **How I computed it** - I fetched every `OrderFulfilled` log from both Seaport contracts over exactly blocks 26019452–26026608. The range went in 500-block chunks, and any chunk the endpoint refused would have been split in half. - I decoded the offer and consideration items and applied the brief's definitions exactly. There were 12232 `OrderFulfilled` logs in the window. 18 involve the collection, and all 18 qualify: 13 listing fills and 5 bid fills. - The delivered `scan.mjs` can't decode Seaport's item lists, so I used a small Node script of my own in `test/scratch/`. It isn't submitted, and `notes` describes what it does. **How I checked it** - The closing block hash matches the pinned one on three endpoints: publicnode, mevblocker and flashbots. - I ran the full scan a second time on mevblocker. It found the same log counts, the same 18 sales and the same sum. - The 18 sales happened in 12 transactions. No transaction has both a listing fill and a bid fill, so no NFT is counted twice. **What differs from the usual recipe** - The brief marks this as a `"evidence": "panel"` question, and the checker only accepts a `panel` recipe for those. So the recipe is `{kind: "panel", source}`, where `source` names the `eth_getLogs` query: the public endpoint, both Seaport addresses, the event topic and the block range. None of the four chain recipe kinds can compute this average anyway. - Under `definitions`, I spelled out the points the brief left implicit: the offer must contain exactly one item, and each log counts as one sale.

The average sale price of Project Lobster over blocks 26019452–26026608 is **1884938888888888 wei**. - **Scan:** I pulled all 12,232 Seaport `OrderFulfilled` logs from Seaport 1.5 and 1.6 over exactly the pinned blocks. The closing block hash matched the pin. - **Sales:** 18 fills qualified under the brief's definitions. None of the fills that touched the collection were excluded for payment token or shape. - **Sum and average:** the prices sum to 33928900000000000 wei. Divided by 18 that is 1884938888888888.9, rounded down. - **Recipe:** the brief is marked `evidence: panel`, so the recipe kind is `panel`. Its `source` names the publicnode endpoint and the `eth_getLogs` query. - **Endpoints:** the notes name the four endpoints the scan rotated among. - **Scan tooling:** I used my own decoder in `test/scratch/run.mjs` instead of `scan.mjs`. `scan.mjs` sums a single data word, so it can't apply the one-NFT and price rules the brief sets. `artifacts/answer.json` is left untracked, as required.

Done. `artifacts/answer.json` is written and passes the plane's check. **Answer: `1884938888888888` wei** (≈ 0.0018849 ETH), the floor of `33928900000000000 / 18`. How it was computed, over exactly blocks 26019452–26026608 on chain 1: 1. Confirmed `eth_chainId` = 1 and the pinned closing hash `0x84272223…` on `ethereum-rpc.publicnode.com` (via the delivered `scan.mjs --pin`) and again on `mainnet.gateway.tenderly.co`. 2. `eth_getLogs` for the collection's ERC-721 `Transfer` over the window → 19 logs in 13 blocks. Because a Seaport ERC-721 fill always emits its `Transfer` in the same transaction, those 13 blocks contain every possible fill — the narrowing is exact, not a sample, and it keeps each `eth_getLogs` well inside a public endpoint's limits. 3. `eth_getLogs` block-by-block on Seaport 1.5 + 1.6 for `OrderFulfilled` → 34 events; decoded `(bytes32, address, SpentItem[], ReceivedItem[])` by hand (the catalogue's `log-sum` can't reach into dynamic struct arrays). 4. 18 qualified: exactly one NFT item, `itemType 2`, token = the collection. 13 listing fills (price = sum of all consideration, all ETH/WETH, fees included) and 5 bid fills (price = the WETH offer amount). All on Seaport 1.6. Checks that ran: all 18 fills matched back to an ERC-721 `Transfer` of the same token id in the same transaction; each log's data decoded with no leftover words; NFT direction verified per side; the one non-matching `Transfer` (block 26019470) is a direct wallet transfer with value 0, correctly excluded. A second operator (Tenderly) reproduced the same 19 transfers, 34 events, 18 sales and identical sum. `eth.drpc.org` returned HTTP 400 on `eth_getLogs` and `eth-mainnet.public.blastapi.io` timed out; both were dropped rather than retried, and that is recorded in `notes`. The brief sets `"evidence": "panel"`, so the recipe is `{ kind: "panel", source }` — the check script refuses any other kind for this brief — with the source naming the exact logs, contracts and block range. Two notes on scope: the workspace's file-write tool refused every path under the working directory, so the scratch scripts live in `$TMPDIR` and the deliverable was copied into `artifacts/`; and `git status` can't run here (`/home/seat/.gitconfig` is unreadable in the sandbox), though nothing was staged or committed — `artifacts/answer.json` is left untracked for the daemon to upload.
I wrote `artifacts/answer.json` with an average sale price of **1884938888888888 wei** (about 0.00188 ETH), and `check-answer.mjs` prints `ok` for it. - **Result:** 18 qualifying sales over blocks 26019452 to 26026608, totalling 33928900000000000 wei, so the average rounds down to 1884938888888888. - **How I computed it:** I pulled every `OrderFulfilled` log from both Seaport contracts in 200-block chunks (12,232 logs). I decoded each against the Seaport ABI and applied the request's definitions for what counts as a sale and its price. The scan script `test/scratch/s.mjs` is not part of the submission. - **Recipe kind:** The brief says `"evidence": "panel"`, and the reference says such a brief takes only the `panel` recipe. So the recipe is `panel`, with the scan's RPC endpoint and the topic0 hash as its source. No catalogue recipe averages decoded Seaport items, so the deployer can't rerun this figure through a catalogue recipe; it would have to repeat my scan. The definitions and notes in the file describe the scan. - **Endpoint checks:** The closing block hash matched the pinned one on `ethereum-rpc.publicnode.com`. The script fell back to `eth.drpc.org` and `rpc.flashbots.net/fast` on errors, and I didn't record which endpoint served which chunk. I did not run a hash check on a second operator's endpoint. The notes say all of this.
Completed `artifacts/answer.json`. Computed result: `1884938888888888` wei. Checks run: `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` → `ok`
`artifacts/answer.json` is untracked output (correctly left out of git, per the task's daemon-upload instructions) and passes `check-answer.mjs` with `ok`. Summary: - Computed the average sale price of Project Lobster (0x7d89c4fee188259e6debefa225b2a6de55fcbeb4) on Seaport over blocks 26019452–26026608 by fetching and decoding all `OrderFulfilled` logs from both Seaport 1.5 and 1.6, filtering to single-ERC-721-of-the-collection fills paid entirely in ETH/WETH per the pinned definitions. - Found 18 qualifying sales, sum 33,928,900,000,000,000 wei, average (floor) = **1,884,938,888,888,888 wei**. - Cross-checked chain id + pinned block hash and the full log fetch/decode on a second independent RPC operator; results matched. - Since the brief's `evidence` is `"panel"`, the recipe is written in the `panel` shape (as `check-answer.mjs` requires) with `source` naming the exact on-chain query used; `notes` explains that no chain-recipe kind (log-sum etc.) can express this conditional struct-array computation, and documents the full method for reproduction.
`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok`. The answer is **1884938888888888** wei, the average sale price of Project Lobster over blocks 26019452–26026608. - **Sales counted:** 18 qualifying sales (13 listing fills, 5 bid fills), all from Seaport 1.6. There were no bundles and no fills paid in tokens other than ETH or WETH. - **Arithmetic:** the prices sum to 33928900000000000 wei, and 33928900000000000 / 18 rounds down to 1884938888888888. - **Scan:** I pulled all 12,232 Seaport 1.5 and 1.6 `OrderFulfilled` logs over the pinned range. I decoded the offer and consideration items myself, because `scan.mjs` can only sum a single data word. The script is in `test/scratch/sales.mjs`, which is not submitted. - **Endpoints:** flashbots, mevblocker and valve.city returned identical totals and the pinned closing hash. Publicnode refused `eth_getLogs` with a 403, and blxrbdn doesn't offer the method. - **Recipe kind:** the brief says `"evidence": "panel"`, so the checker only accepts a `panel` recipe. Its `source` is the flashbots RPC URL, and the full method is in `notes`. - **Open point:** each event is counted on its own, as the definitions say. A `matchOrders` transaction that emitted both a listing and a bid event for one token would count twice. I didn't check the 18 sales for that. The first attempt at `artifacts/answer.json` had the `window` keys in the wrong order, which the checker rejected. I reordered them to match the brief.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **1884938888888888** wei, the average of 18 qualifying sales. - **Method:** I did not scan `OrderFulfilled` directly, because the collection isn't an indexed field, so a scan would pull every Seaport fill in the window. Instead I fetched the collection's ERC-721 Transfer logs over blocks 26019452–26026608 (19 logs in 13 transactions). I then decoded every Seaport 1.5 and 1.6 `OrderFulfilled` event in those transactions' receipts. A fill of the collection always moves a token, so this reaches the same events. I did not run a direct `OrderFulfilled` scan to confirm it. - **Result:** the 18 sales sum to 33928900000000000 wei, a mean of 1884938888888888.88, rounded down. No fills were excluded as bundles or non-ETH/WETH payments. - **Pin:** the closing block hash matched on `ethereum-rpc.publicnode.com` and `rpc.mevblocker.io/fast`. `rpc.flashbots.net/fast` was also in the rotation. - **Recipe:** the brief says `"evidence": "panel"`, so the recipe is `{kind: "panel", source: <URL>}` and can't be a chain recipe. The source is `https://ethereum-rpc.publicnode.com`. - **Definitions and notes:** `definitions` states how sale, price and average were applied. `notes` names the endpoints used. - **Earlier rejection:** it was a 401 from an OpenAI endpoint, which didn't come from anything in the repo, and this run made no calls to it. The scratch scripts are in `test/scratch/` and aren't submitted. The answer file is untracked.
`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The answer is **1884938888888888** wei. - **Figure:** 18 qualifying sales (13 listing fills and 5 bid fills) totalling 33,928,900,000,000,000 wei. Rounded down, the average is 1,884,938,888,888,888 wei. - **Scan:** I fetched every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly blocks 26019452–26026608 and decoded them myself. That was 12,232 logs from `https://ethereum-rpc.publicnode.com`, scanned in 250-block chunks. - **Exclusions:** No fills were excluded for bundles, other NFTs or payment in another token. - **Verification:** The closing block hash `0x84272223…bf3f` matches on publicnode, `rpc.mevblocker.io` and `rpc.flashbots.net`. I did not run a second full scan. - **Recipe:** The brief says `"evidence": "panel"`, so the checker only accepts a `panel` recipe. I put the RPC endpoint and the log query in `source`, and the decoding rules in `definitions` and `notes`. - **Previous failure:** The earlier rejection was a 401 from an OpenAI API call. This run makes no such call. The scratch script is `test/scratch/run.mjs`. It is deleted before submission and is not part of the deliverable.

The average sale price was **1884938888888888 wei** (about 0.001885 ETH). It's written to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **Endpoint and window:** the endpoint reported chain 1, and the hash of block 26026608 matched the pinned hash. I fetched every `OrderFulfilled` event from both Seaport contracts (1.5 and 1.6) over exactly blocks 26019452 to 26026608. That was 12,232 events. - **Qualifying sales:** 18 events were fills of exactly one Project Lobster ERC-721 token paid in ETH or WETH. None had to be excluded as bundles, ERC-1155 fills or other payment tokens. Together they sum to 33928900000000000 wei, and dividing by 18 and rounding down gives the answer. - **Second scan:** I reran the full scan on `eth.drpc.org` (falling back to `rpc.mevblocker.io`) and got the same event count, sale count and sum. - **Recipe:** the brief marks this as a panel-evidence question, so the only recipe the checker accepts is `panel`. Its `source` names the exact `eth_getLogs` query: the event, both contract addresses, the block range and the closing hash. - **Scan method:** I didn't use the provided `scan.mjs`. It can't decode the offer and consideration lists inside each event, which is needed to pick out this collection's sales, so I used my own Node script in `test/scratch/`. The notes in the answer file say this. - **Definitions:** they restate the brief's definitions and add one choice: each qualifying event counts as one sale. The previous attempt failed because it couldn't authenticate to an outside API. This one called only public Ethereum RPC endpoints and needed no keys. The answer file is left untracked, as required.

`artifacts/answer.json` is written and `check-answer.mjs` prints **ok**. **Answer: 1884938888888888 wei** (≈0.0018849 ETH) — the mean of 18 qualifying Seaport sales summing to 33,928,900,000,000,000 wei. How it was computed, over exactly blocks 26019452–26026608: - **Pin confirmed** on three independent operators (flashbots, publicnode, drpc): block 26026608 hash matches the brief, `eth_chainId` = 1. - **Route A — the source the definitions name:** `eth_getLogs` for the `OrderFulfilled` topic on Seaport 1.5 and 1.6 across the window in 100-block chunks (72 chunks, none refused). 12,232 OrderFulfilled logs; 18 name the collection; all 18 qualify — 13 listing fills (native-ETH considerations summed, fees included), 5 bid fills (WETH offer amount). None rejected as bundle, ERC-1155 or other currency. - **Route B — cross-check:** the collection's own ERC-721 `Transfer` logs (19 transfers, 13 transactions) → receipts → same decode. Identical count, sum and mean, and no transaction moved the same token id twice, so nothing is double-counted. Both scans ran from purpose-written Node scripts in `test/scratch/` (the delivered `scan.mjs` sums fixed data words and can't reach a price inside Seaport's dynamic arrays); neither printed a log. Two judgment calls worth flagging, both stated under `definitions`: - The brief sets `"evidence": "panel"`, and `check-answer.mjs` refuses any non-panel recipe for such a brief — so the recipe is `{ kind: "panel", source }`, with `source` carrying the full chain query (endpoint, topic, both Seaport addresses, pinned blocks, filter, reduction) so it still reproduces from public RPC data alone. - "On OpenSea" is taken exactly as the brief's `sale` definition writes it: any Seaport 1.5/1.6 fill, with no filter on zone, conduit or fee recipient.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price is **1884938888888888 wei**, which is 33928900000000000 wei over 18 qualifying sales, rounded down. - **Recipe kind:** `oracle.json` says `"evidence": "panel"`, so the recipe has to be `{ kind: "panel", source }` even though the figure comes from chain data. The source is the RPC URL and the Seaport addresses and blocks I read. - **Chain and pin:** `eth_chainId` returned 1 and the closing block hash matched the pin. - **Method:** - I took the collection's `Transfer` logs over the window (19 logs in 13 blocks). - I fetched Seaport 1.5 and 1.6 `OrderFulfilled` logs in only those blocks and decoded them by hand. - Any Seaport sale must move the token, so those blocks cover every sale. - I used my own script rather than `scan.mjs`, which can't decode Seaport's nested arrays. It's in `test/scratch/` and isn't submitted. - **Sales:** 18 of the 19 transfers qualified. Listing price is the sum of all consideration amounts, fees included, only if every item is ETH or WETH. Bid price is the single ETH/WETH offer amount. - **Endpoint:** `https://ethereum-rpc.publicnode.com` only; no fallback was needed. I did not scan the window without the Transfer pre-filter, so nothing cross-checks that shortcut. The 19th transfer isn't a Seaport sale of that shape, and I didn't look at what it was.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` for it. **Answer:** 1884938888888888 wei, the average sale price of Project Lobster on Seaport over blocks 26019452 to 26026608. - **Sales:** 18 sales qualified, and their prices sum to 33928900000000000 wei. - **Scan:** I fetched every OrderFulfilled log from Seaport 1.5 and 1.6 over the pinned window from `https://ethereum-rpc.publicnode.com`. That was 12,232 logs, decoded by hand with a script in `test/scratch/`. That RPC confirmed chain id 1 and the pinned closing block hash. I did not check the hash on a second endpoint. - **Definitions:** each sale contains exactly one NFT item, an ERC-721 of the collection. Listing fills sum every consideration amount and must be all ETH or WETH. Bid fills use the ETH or WETH offer amount. These are stated under `definitions` in the file. - **Recipe:** the brief is panel-evidence, so the checker only accepts a `panel` recipe, and mine cites the RPC URL as its source. I first tried a `log-sum` recipe and the checker rejected it. Because of that, the recipe does not describe the filtering, and a rerun has to follow the method in `notes`. The previous attempt's 401 error came from an OpenAI API call in that attempt's own runtime, so it isn't reproduced here. Nothing in this work calls that service.

Done. The workspace's `.git/info/exclude` already ignores `artifacts/` and `test/scratch/`, so both stay untracked as required — the daemon picks up `artifacts/answer.json` by path. **Answer: 1884938888888888 wei** (~0.00188 ETH average sale price), and `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs` prints `ok`. How it was computed, exactly per the brief's definitions: - Fetched every `OrderFulfilled` log (topic0 `0x9d9af8…6f31`) from Seaport 1.5 and 1.6 over exactly blocks 26019452–26026608, with a scratch Node script in `test/scratch/avg.mjs` that decodes each log's offer/consideration arrays with the Seaport ABI (the provided scan.mjs can only sum a single data word, so it can't apply these definitions). - Of 12232 `OrderFulfilled` logs in the window, **18 qualify** for collection `0x7d89c4…beb4`: exactly one ERC-721 (itemType 2) of the collection and no other NFT in the fill, paid entirely in native ETH or WETH — 13 listing fills (price = sum of all consideration amounts, fees included) and 5 bid fills (price = the single offer amount), all on Seaport 1.6. - Sum of prices = 33928900000000000 wei (recorded as `figure`); average = floor(sum / 18) = **1884938888888888**, satisfying the `min: 1` guard. - Verified: `eth_chainId` = 1 and the pinned closing hash `0x842722…fbf3f` matched on both endpoints used; since this is a panel-evidence question where exact value agreement is the evidence, I recomputed once on a second operator (`ethereum-rpc.publicnode.com`, different chunk size) after the primary scan on `rpc.flashbots.net/fast` — identical log count, sales, sum, and average, ruling out silent truncation. The answer file copies the request id, chain, and window verbatim from the brief (window in the brief's exact key order, since the checker compares serialized JSON), uses the required `{kind: "panel", source}` recipe naming the primary RPC URL, and states every choice the question left open under `definitions` — notably that each qualifying `OrderFulfilled` event counts once with no dedupe of matchOrders mirror events, and no OpenSea-specific zone/fee filter beyond the two Seaport contracts, exactly as the pinned definitions specify.
