Average: **1,888,368,597,349,397 wei** across 83 qualifying sales. Wrote `artifacts/answer.json` with the pinned window and reproduction procedure. Required checker printed `ok`.

Answer: **1888368597349397 wei** (83 qualifying Seaport 1.6 fills, sum 156734593579999999 wei, mean floored). `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` prints `ok`.

I wrote `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. The average sale price of The Seven Houses over blocks 26019451–26026607 is **1888368597349397 wei**. - **Count and total:** 83 qualifying sales, 39 listing fills and 44 bid fills, totalling 156734593579999999 wei. None were excluded as bundles or for other payment tokens. - **How I got it:** I pulled the Seaport 1.5 and 1.6 `OrderFulfilled` logs for exactly the pinned range and decoded them with my own script. The provided `scan.mjs` doesn't decode Seaport's nested item arrays. My script is in `test/scratch/`, so it isn't submitted. - **Cross-check:** Three RPC operators (`rpc.mevblocker.io/fast`, the nodereal endpoint, `rpc.flashbots.net/fast`) each returned the pinned closing hash and the same 12231 logs and 83 sales. The task guidance said one scan was enough, so the extra runs were cheap confirmation. - **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. The definitions and notes describe the on-chain computation. The definitions in the answer state the sale rule, the price rule for listings and bids, and the rounding.

Done. `artifacts/answer.json` is written (untracked, as required) and `check-answer.mjs` prints `ok`. **Answer: 1888368597349397 wei** (≈0.001888 ETH) — average over 83 qualifying sales, sum 156734593579999999 wei, floored. How it was computed, over exactly blocks 26019451–26026607 on chain 1: - Confirmed `eth_chainId = 1` and the pinned closing hash `0x8a84f5aa…cdec2` on three operators (publicnode, drpc, blockpi). - `eth_getLogs` for the collection's ERC-721 `Transfer` over the window: 83 transfers in 46 blocks — same count from publicnode and blockpi, so the chunked step wasn't truncated. - `eth_getLogs` for Seaport `OrderFulfilled` (topic0 `0x9d9af8e3…6f31`) on Seaport 1.5 and 1.6, in those 46 blocks: 140 events, decoded in-process with the Seaport ABI. Restricting to those blocks loses nothing — an ERC-721 fill necessarily emits that collection's Transfer in the same block — and the decode confirms the fit: exactly 83 of the 140 carry a collection ERC-721 item, one per Transfer. - 39 listing fills (offer = the NFT → price = sum of all consideration, all ETH/WETH, fees included) and 44 bid fills (offer = ETH/WETH → price = the offer amount). Zero exclusions for a non-ETH/WETH consideration, a bundle, or an ERC-1155 item, and no matchOrders mirror pair, so none of the open choices moved the figure. - The entire scan was reproduced to the wei on a second operator (blockpi). One thing worth flagging: the brief carries `"evidence": "panel"`, so the check requires `{kind: "panel", source}` — and no chain recipe in the catalogue can express a conditional sum over Seaport's two dynamic item arrays anyway. The `source` names the RPC endpoint, contracts, topic and window so the reduction is reproducible from public RPC data alone; the reduction itself is spelled out under `definitions` and `notes`.

`ok` from the checker. Summary of the deliverable: **Answer: 1888368597349397 wei** (≈0.0018884 ETH) — the floor mean of 83 qualifying Seaport sales totalling 156734593579999999 wei. How it was computed, over exactly blocks 26019451–26026607: 1. `scan.mjs` with `--pin` on `https://rpc.flashbots.net/fast` confirmed chain id 1 and the pinned closing hash, and returned the collection's 83 ERC-721 `Transfer` logs across 46 blocks (0 mints). 2. A scratch script read `OrderFulfilled` (topic0 `0x9d9af8e3…`, verified with `--keccak`) from Seaport 1.5 and 1.6 in exactly those 46 blocks — lossless, since any qualifying fill moves the token in the same block — and decoded `(orderHash, recipient, SpentItem[], ReceivedItem[])`. 3. 140 events, 83 carrying the collection, all 83 qualifying: 39 listing fills (sum of consideration, all ETH/WETH, fees in) and 44 bid fills (offer amount). Nothing excluded — no bundles, no ERC-1155, no other currency. Decoding checks out against the price distribution: 39 distinct prices from 0.0011 to 0.007 ETH, nearly all round ETH amounts. `https://rpc.mevblocker.io/fast` (second operator) returned the same chain id and closing hash, and an independent full read there produced the identical sum and count. Two things worth flagging: - 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: "<rpc url>" }` even though the fact is a chain computation. The catalogue's chain recipes could not express this anyway — `log-sum` sums one fixed data word and cannot decode Seaport's dynamic offer/consideration arrays or divide by a count. The full procedure is in `notes` so the panel can compare method, not just number. - One judgement call, stated under `definitions.matched_orders`: 5 trades emitted two qualifying events each (both halves of a Seaport match, one NFT transfer). The brief defines a sale *as* the event and prices each half separately, so both were counted. Counting those once instead would give 78 sales — a different answer, and the likeliest source of panel disagreement.

Done. `artifacts/answer.json` is written and the plane's checker prints `ok`. **Answer: 1888368597349397 wei** (≈0.0018884 ETH) average sale price. How it was computed, over exactly blocks 26019451–26026607: - **Pin confirmed** on `https://ethereum-rpc.publicnode.com`: `eth_chainId` = 0x1, block 26026607 hash = `0x8a84f5aa…cdec2`. `https://eth.drpc.org` was tried first but refused chunked `eth_getLogs` ("Can't route your request to suitable provider"); `https://rpc.flashbots.net/fast` independently returned the same 83-log count for the collection over the window. - **Scan**: one `eth_getLogs` on the collection → 83 ERC-721 `Transfer` logs in 46 txs; those 46 receipts decoded → 83 `OrderFulfilled` events (all Seaport 1.6), all 83 qualifying — one itemType-2 item of the collection, no other NFT, paid entirely in ETH/WETH. Nothing excluded as bundle, ERC-1155, multi-item offer or foreign token. - 39 listing fills (price = sum of all consideration, fees included), 44 bid fills (price = the single ETH/WETH offer amount). Total 156734593579999999 wei / 83 = 1888368597349397 (remainder 48, floored). Guard `min: 1` satisfied. One judgement call, stated in `definitions` and `notes`: 5 fills were matched orders, where Seaport emits two events (bid half + listing half) for one NFT transfer. The request defines a sale as an `OrderFulfilled` event, so both halves count and the denominator is 83. The alternative economic reading — 78 transfers, taking the fee-inclusive bid side — would give 1921443507435897 wei; that figure is recorded in `notes` but is not the answer. The brief carries `"evidence": "panel"`, so the recipe is `{kind: "panel", source}` (the checker rejects a chain recipe here); the `source` names the endpoint and the exact calls, so a rerunner reproduces it from public RPC data alone. No chain recipe could express it — `log-sum` can't decode Seaport's nested item arrays, filter by collection, or divide by a count.

The average sale price of The Seven Houses over the pinned window was **1888368597349397 wei** (about 0.00189 ETH). I wrote this to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. **How I got it** - I pulled every `OrderFulfilled` log from both Seaport contracts (1.5 and 1.6) over exactly blocks 26019451–26026607 from `ethereum-rpc.publicnode.com`. I fetched in 500-block chunks and split any chunk the endpoint refused. - The chain id was 1 and the closing block hash matched the pinned one. I also confirmed that hash on a second endpoint, `eth-mainnet.nodereal.io`. - There were 12231 logs in total. I decoded each one and applied the request's definitions. - **Result:** 83 qualifying sales, all on Seaport 1.6: 39 listing fills and 44 bid fills. No listing fill had a price of zero. - The prices add up to 156734593579999999 wei (the `figure`), and dividing by 83 and rounding down gives the answer. - I ran the full scan a second time on the same endpoint and got the same log count and the same result. It was not checked against a different endpoint. **Choices a reviewer should know about** - **Scan script:** the provided `scan.mjs` can only count or sum simple log fields; it can't decode Seaport's item lists. I wrote my own Node decoder in `test/scratch/`, which is not submitted, so the method is written out in `notes`. - **Recipe:** the request is marked `evidence: panel`, so the only recipe the checker accepts is `kind: panel`. Its `source` names the endpoint and the exact log query. - **Counting:** following the request's definition literally, each qualifying event counts as one sale. I did not try to pair up events within the same transaction. - **Offer rule:** I only counted fills whose offer had exactly one item, since the definitions describe both fill types that way. I changed no files other than `artifacts/answer.json`, and I left it uncommitted as instructed.

Completed `artifacts/answer.json`. Result: `1888368597349397` wei. Checks run: - Full public RPC scan on Flashbots: matched pin, 83 qualifying sales - Full public RPC scan on MEV Blocker: same result - `node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs artifacts/answer.json .imd/reads/oracle.json` printed `ok`

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. The average sale price is **1888368597349397 wei**, about 0.0019 ETH. - **Scan:** I pulled every OrderFulfilled log from Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607, 12,231 logs in all, from `ethereum-rpc.publicnode.com`. The chain id and the closing block hash matched the pin. - **Sales:** I decoded each event with the Seaport ABI and kept only fills with exactly one ERC-721 item of the collection and no other NFT. The price rule was the brief's: the summed ETH/WETH consideration for a listing fill, and the ETH/WETH offer amount for a bid fill. 83 sales qualified and none were excluded. - **Result:** the prices sum to 156734593579999999 wei, and dividing by 83 and rounding down gives the answer above. - **Scan script:** the provided `scan.mjs` can't decode OrderFulfilled, so I used my own script in `test/scratch/`. It is not submitted. - **Recipe kind:** because the brief says `"evidence": "panel"`, the checker only accepts a `panel` recipe. The recipe's `source` is therefore the endpoint and the scan parameters, and the full method is in `notes`.

Created `artifacts/answer.json` with **1,888,368,597,349,397 wei**, averaged over 83 qualifying sales, and a self-contained RPC replay procedure. The required checker prints `ok`.

`artifacts/answer.json` is written, and the check script prints `ok` for it. The average sale price is **1888368597349397 wei**. That is 156734593579999999 wei summed over 83 qualifying sales, rounded down. - **How I computed it:** I fetched the collection's `Transfer` logs over blocks 26019451–26026607, which gave 46 blocks with activity. In those blocks only, I fetched `OrderFulfilled` logs from both Seaport contracts and decoded the offer and consideration items by hand. I then applied the request's definitions. - **Endpoint and pin:** I read from `https://ethereum-rpc.publicnode.com` only. I confirmed the closing block hash matches the pin on that endpoint. I did not check it on a second operator's endpoint. - **Recipe:** The brief says `"evidence": "panel"`, so the only allowed recipe kind is `panel`. Its `source` is the RPC URL above. The deployer's rerun of a panel recipe is not a log re-scan, so it may not reproduce the number from this recipe alone. The `notes` field in the file describes the actual method. - **Scan tooling:** I did not use the delivered `scan.mjs` for the scan, because it cannot decode nested `OrderFulfilled` items. I imported only its `keccak256` helper. My scan script is in `test/scratch/`, which is not submitted.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The average sale price comes out at **1888368597349397 wei**, about 0.00189 ETH. - **Sales counted:** 83 qualifying Seaport fills over blocks 26019451–26026607, of which 39 are listing fills and 44 are bid fills. None were excluded as bundles, other NFTs or non-ETH/WETH payments. - **Sum and average:** the prices add up to 156734593579999999 wei, which is the `figure`. Dividing by 83 and rounding down gives the answer. - **Method:** I fetched the collection's ERC-721 Transfer logs (83 transfers in 46 transactions), pulled those transactions' receipts, and decoded each Seaport 1.5 and 1.6 `OrderFulfilled` event. I used my own script rather than `scan.mjs`, because the filter needs the decoded item arrays. - **Pin check:** I confirmed the chain id and the closing block hash on `ethereum-rpc.publicnode.com`, which I read the logs from, and the hash also matches on `rpc.flashbots.net/fast`. I ran one full scan only. - **Recipe kind:** the brief says `"evidence": "panel"`, and the checker requires a `panel` recipe for those, so the recipe is `{kind: "panel", source: <publicnode URL and method>}`. That means the deployer can't rerun it as a chain recipe. The `notes` field records the exact steps instead.

Created `artifacts/answer.json` with **1,888,368,597,349,397 wei**, averaged over 83 qualifying sales, plus the reproduction procedure. The embedded calculation matched the captured RPC data. The required checker printed `ok`.

Done. `artifacts/answer.json` is written, passes `check-answer.mjs` (`ok`), and is left untracked (git status is clean apart from the ignored/untracked output). **Answer: `1888368597349397` wei** (≈0.001888 ETH) How it was computed: - `eth_getLogs` on `https://rpc.flashbots.net/fast` (chain id 1, closing block 26026607 hash matched the pin; also confirmed on `ethereum-rpc.publicnode.com`) for the `OrderFulfilled` topic on Seaport 1.5 and 1.6 over exactly blocks 26019451–26026607, in 1000-block chunks, none refused. - 12,231 `OrderFulfilled` logs in the window; 83 touched The Seven Houses and all 83 qualified under the brief's definitions (39 listing fills paid entirely in ETH/WETH, 44 bid fills with a single ETH/WETH offer item; no bundles, ERC-1155 or other-token fills). All were on Seaport 1.6. - Sum of prices 156,734,593,579,999,999 wei ÷ 83 = 1,888,368,597,349,397.58…, floored. Since the brief is `"evidence": "panel"`, the recipe is `{ kind: "panel", source: <the RPC endpoint> }`; the full method, counts, and the scratch command are in `notes`, and every open definition (dedup, ETH/WETH 1:1 in wei, the exact item-shape test) is stated under `definitions`. The decoding script lives in `test/scratch/avg.mjs`, which is not submitted.

The average sale price was **1888368597349397 wei** (about 0.00189 ETH). That answer is in `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. - **Scan:** I pulled every `OrderFulfilled` log from both Seaport contracts (1.5 and 1.6) over blocks 26019451 through 26026607, using `https://ethereum-rpc.publicnode.com`. That returned 12,231 logs. The chain id was 1 and the closing block hash matched the pin, which I also confirmed on `https://eth.drpc.org`. - **Count:** I decoded each fill and applied the definitions exactly as the brief states them. 83 fills were single sales of one The Seven Houses token paid in ETH or WETH. None had to be dropped as bundles, as including other NFTs, or as paid in another token. - **Result:** the 83 prices add up to 156734593579999999 wei (fees included). Dividing by 83 and rounding down gives 1888368597349397 wei. - **Recipe:** the brief marks this as a panel-evidence question, so the only recipe kind allowed is `panel`. Its `source` names the endpoint, the event topic, both Seaport addresses and the block range. The `definitions` and `notes` fields say how sales and prices were counted. The first check failed only because the window's keys were in a different order from the brief's; reordering them fixed it. The answer file is untracked, as the task requires. The decoding script is in `test/scratch/`, which is deleted before submission.

Done. `artifacts/answer.json` is written, passes the plane's own check (`ok`), and is left untracked for the daemon to pick up. **The answer: 1888368597349397 wei (~0.00189 ETH) average sale price.** How it was computed, over exactly the pinned window (blocks 26019451–26026607, closing hash confirmed against the pin on `ethereum-rpc.publicnode.com` and cross-checked on a second operator, `rpc.mevblocker.io`): - I fetched every `OrderFulfilled` log from both Seaport 1.5 and 1.6 via chunked `eth_getLogs` (no chunk was refused, so the scan is whole — 12,231 logs), decoding the offer/consideration arrays with a small scaffold in `test/scratch/avg.mjs` that prints only totals. - Applying the request's pinned definitions left **83 qualifying sales** of The Seven Houses — 39 listing fills (price = sum of all consideration amounts, all of which had to be ETH/WETH) and 44 bid fills (price = the single ETH/WETH offer amount). Nothing was excluded for shape or for payment in another token. - Total 156,734,593,579,999,999 wei ÷ 83, floored = **1,888,368,597,349,397 wei**, which satisfies the `min: 1` guard. Because the brief declares `"evidence": "panel"`, the recipe is the `panel` kind naming the RPC endpoint as the source (the check script rejects any chain recipe for a panel-evidence brief). The one definition gap the request left open — that only single-offer-item fills fit its two price rules, and that a bid fill's consideration side carries no ETH/WETH-only constraint — is stated under `definitions` and applied consistently.

Created `artifacts/answer.json` with **1,888,368,597,349,397 wei**, averaged over 83 qualifying sales. The included reproduction procedure returned the same result. The required checker printed `ok`.

Created `artifacts/answer.json`: **1888368597349397 wei**, averaged over 83 qualifying sales. The included reproduction code returned the same result, and `check-answer.mjs` printed `ok`.

I wrote `artifacts/answer.json` with an answer of **1888368597349397** wei. `check-answer.mjs` prints `ok` for it. - **Sales:** 83 fills qualified over blocks 26019451–26026607. I decoded 12,231 Seaport 1.5 and 1.6 `OrderFulfilled` logs and kept those matching the request's definitions. - **Sum:** the qualifying prices add up to 156734593579999999 wei, which is the `figure` field. Divided by 83 and rounded down, that gives the answer. - **Endpoints and pin:** I read from `ethereum-rpc.publicnode.com`, `rpc.mevblocker.io/fast` and `eth-mainnet.nodereal.io`. The closing block hash matched the pin. - **Recipe kind:** the request sets `"evidence": "panel"`, and the reference says such briefs take only the `panel` recipe. I therefore used `panel` with `https://ethereum-rpc.publicnode.com` as the source, and the notes describe the actual computation. - **How I ran it:** I used my own script in `test/scratch/` rather than `scan.mjs`. `scan.mjs` can only sum a data word or a topic. Seaport's nested offer and consideration arrays need custom decoding.
