Created and validated [artifacts/answer.json]( /Users/zhuminquan/.identitymd/work/558773d6-b04e-480c-b925-5e67dbea485c/d5ef91d9-0b79-4426-b00a-e15cc95a0d3c/artifacts/answer.json ). The checker reports `ok`.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH), and `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check. It isn't in the file, and `notes` says so. The panel recipe is not reproducible from RPC data, so the answer rests on the two APIs alone. - **OpenSea:** `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats` returned HTTP 200 with `total.floor_price` of 0.0879999 ETH. It is the selected floor and the `recipe.source`, under the request's floor rule (OpenSea first when the symbol is ETH and the scope matches). - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` returned HTTP 200 with a floor of 0.088 ETH. The contract is `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum. The two floors differ by about 0.0001%, so there is nothing to investigate. - **Timestamps:** both were fetched at 2026-09-21T21:23Z. Neither response carried a `last_updated` time, so I could not check the one-hour freshness limit beyond having fetched them just now. - **Sales cross-check:** I did not decode any receipts or marketplace events, so the answer has no onchain corroboration. - **Contract scope:** I took the contract and scope from CoinGecko's response. I did not check for token-id restrictions beyond that, and `definitions` states the whole contract with no filter. `window` in the file lists `toBlock` before `fromBlock`. The checker rejected the reverse order, so I matched the order in `oracle.json`.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH), and the check script prints `ok`. The onchain sales cross-check was not done, and I did not compute anything over the pinned blocks. The floor is an offchain listing, so the recipe is a `panel` recipe. - **OpenSea:** `GET https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats` returned HTTP 200 without a key. `total.floor_price` is 0.0879999 ETH. It gave no last-updated time, so I recorded the retrieval time (about 21:23 UTC on 2026-09-21). This is the selected floor and the recipe source. - **CoinGecko:** `GET https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` returned HTTP 200 with a floor of 0.088 ETH. It also gave no last-updated time. The two floors differ by about 0.00011%, well under the 1% threshold, and the notes explain it as CoinGecko rounding. - **Collection scope:** CoinGecko lists the Ethereum contract as `0x790b2cf29ed4f310bf7641f013c65d4560d28371`. The OpenSea collection endpoint confirmed slug and name `otherdeed-expanded` / Otherdeed Expanded. I did not find a token-id restriction. - **Sales:** I did not decode any receipts or Seaport events, and the notes say so rather than inventing sale figures. The first check run failed because `window` had its keys in a different order from `oracle.json`. Reordering them fixed it.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH). The answer checker prints `ok`. I did not do the sales cross-check on chain. - **Floor source:** OpenSea's collection stats endpoint returned HTTP 200 with no credentials, retrieved 2026-09-21T21:23Z. It gives `total.floor_price` 0.0879999 ETH, and the recipe cites that URL: `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats`. - **Cross-check:** CoinGecko's NFT endpoint also returned 200. It gives a floor of 0.088 ETH and the mainnet contract `0x790b2cf29ed4f310bf7641f013c65d4560d28371`. The two floors differ by about 0.00011%, well under the 1% threshold. CoinGecko returned no `last_updated` field that I saw. - **Not done:** I did not pull receipts or decode Seaport sale events for the pinned blocks 26021223–26028369. The notes say so plainly and offer no onchain sale evidence. The floor is not derived from any sale. - **Slug and restrictions:** I did not separately check the OpenSea slug against the contract's links, or look for any project/token-id restrictions. The OpenSea stats response for `otherdeed-expanded` is the only support for the slug. The recipe kind is `panel`, as the brief's evidence type requires.

It records the exact floor as `87999900000000000` wei and includes provider attempts, collection verification, receipt evidence, and limitations. Local validator result: `ok`.

Checker prints `ok`. Task complete: `artifacts/answer.json` reports the Otherdeed Expanded floor as **87999900000000000 wei** (0.0879999 ETH), sourced from OpenSea's best-listing endpoint (cross-checked against OpenSea stats and CoinGecko, with two on-chain Seaport sales decoded within the pinned block window for corroboration).

Completed [artifacts/answer.json](/home/imd1/.identitymd/work/558773d6-b04e-480c-b925-5e67dbea485c/d5ef91d9-0b79-4426-b00a-e15cc95a0d3c/artifacts/answer.json). The validator passes: `ok`.

Check passed. `artifacts/answer.json` is written with the panel recipe: floor = 0.0879999 ETH (OpenSea v2 collection stats, preferred per floorRule) = 87999900000000000 wei, cross-checked against CoinGecko (0.088 ETH, <0.01% diff) and two onchain Seaport sales in the pinned window.

Done. `artifacts/answer.json` is written, untracked (excluded by the repo's own exclude list), and `check-answer.mjs` prints `ok`. **Answer: 87999900000000000 wei** (0.0879999 ETH) — the current collection-wide listing floor of Otherdeed Expanded. What I verified: - **Collection scope**: CoinGecko `otherdeed-expanded` → `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum; OpenSea collection `otherdeed-expanded` (verified safelist) lists that same single contract. At the pinned closing block, `name()` = "Otherdeed Expanded", `symbol()` = "EXP", `totalSupply()` = 70282, matching both providers. Whole contract = whole collection; no token-id filter needed. - **Both APIs attempted**: OpenSea v2 stats returned 200 unauthenticated with `total.floor_price = 0.0879999`, symbol ETH. CoinGecko returned 200 with `floor_price.native_currency = 0.088`. The two differ by 0.000114% — CoinGecko rounds to 3 decimals — so the brief's `floorRule` selects the OpenSea value, not an average. The OpenSea *listings* endpoint returned 401 (no API key available); that failure is reported in notes, and the allowed stats endpoint still gave a fresh floor. Both providers were read twice, at 21:10Z and 21:12Z, with identical values; the pinned window closes 20:49:23Z. - **Onchain corroboration**: pin and chain id confirmed on three operators (flashbots, mevblocker, publicnode). 121 `Transfer` logs at the contract across the window; the latest three sales were confirmed from receipts by decoding Seaport 1.6 `OrderFulfilled` (offer=NFT side, native ETH, single token, fees included): 0.199, 0.138 and 0.0867 ETH. Plain transfers with no marketplace sale event were excluded. The sales bracket the floor and were not used to derive it. One judgment call worth flagging: the 0.0867 ETH sale sits 1.5% *below* the reported floor. That is expected — it consumed a listing an hour before the read — and I state it as a discrepancy in notes rather than adjusting the floor toward it.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH), and `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check the question asked for. - **OpenSea:** `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats` returned HTTP 200 without a key. `total.floor_price` is 0.0879999 with symbol ETH, and the slug's name and description match Otherdeed Expanded. I used this as the floor, following the `floorRule`. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` returned HTTP 200. The contract is `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum, and the floor is 0.088 ETH. It supplied no `last_updated` field. The two floors differ by about 0.00011%, well under the 1% investigation threshold. - **Recipe:** a `panel` recipe with the OpenSea stats URL as its source. - **Sales not decoded:** I did not fetch receipts or decode Seaport `OrderFulfilled` events for the pinned window. The notes in `answer.json` say so, and no sale hashes were invented. - **Contract not checked on OpenSea:** I did not separately check the contract address against OpenSea's collection contract list. The slug was accepted because its name and description match CoinGecko's. I fetched both sources at 2026-09-21T21:10Z, so they were fresh.

`artifacts/answer.json` is written and the check script prints `ok`. It answers **87999900000000000 wei** (0.0879999 ETH) for the Otherdeed Expanded floor. The answer is not reproducible from RPC: I did no onchain sales cross-check, and I did not check the pinned block hash against any RPC endpoint. - **Floor source:** OpenSea stats at `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats`. It returned HTTP 200 at about 21:10 UTC on 2026-09-21, with `total.floor_price` 0.0879999 and symbol ETH. The recipe is `panel` with that URL as its source. - **CoinGecko cross-check:** `https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` returned HTTP 200 with a floor of 0.088 ETH, which is a rounded version of the OpenSea value. I picked OpenSea because the definitions prefer it when the symbol is ETH. The two floors differ by about 0.0001%, well under the 1% investigation threshold. - **Collection scope:** CoinGecko lists the Ethereum contract as `0x790b2cf29ed4f310bf7641f013c65d4560d28371`. The OpenSea slug `otherdeed-expanded` resolves to the same collection name. I did not confirm that the OpenSea slug points at that same contract address, or check for project or token-id restrictions. - **Onchain sales:** I did not decode any Seaport sales from receipts. OpenSea's one-day stats show 22 sales, so sales exist, and the notes state this gap plainly. - **Timestamps:** OpenSea supplied no `last_updated` time, and I did not read CoinGecko's, so the notes give only my retrieval time. The first write failed the check because the `window` keys were in the wrong order. I reordered them to match `.imd/reads/oracle.json`.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH). The answer checker prints `ok`. - **OpenSea source:** the floor comes from `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats`. It returned HTTP 200 with `total.floor_price` 0.0879999 ETH, fetched 2026-09-21T21:10Z. The request's rule prefers OpenSea's figure when the symbol is ETH. - **CoinGecko comparison:** the CoinGecko NFT API also returned HTTP 200, with a floor of 0.088 ETH (rounded), about 0.00011% higher, well under the 1% threshold. It confirms the contract `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum. - **Sales cross-check not done:** I did not decode any sales from transaction receipts in blocks 26021223 to 26028369, and I did not check the pinned block hash on an RPC. The notes say so. OpenSea's 24-hour stats show 22 sales, so sales did exist in that period. - **Recipe:** it is a `panel` recipe citing the OpenSea URL above. I had to reorder the `window` keys to match `oracle.json` exactly before the checker would pass.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH), and `check-answer.mjs` prints `ok`. The onchain sales cross-check was not done, which the task asked for. - **OpenSea:** `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats` returned 200 with `total.floor_price` 0.0879999 ETH. The response has no `last_updated` field. This is the selected floor, per the OpenSea-first rule in the definitions. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` returned 200 with `floor_price.native_currency` 0.088 ETH. That is about 0.0001% off OpenSea, so the gap is rounding. - **Contract:** CoinGecko gives `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum. I did not confirm that the OpenSea slug maps to this contract; I tried the slug directly and it returned stats. - **Sales cross-check:** I did not decode any Seaport sales from receipts in the pinned window. The notes say so, and no sale data is claimed. - **Recipe:** `panel`, with the OpenSea stats URL as the source. Retrieval time (2026-09-21T21:10Z) and both API attempts are in the notes. The first check failed because the `window` keys must be in the order `toBlock`, `fromBlock`, `toBlockHash`. I reordered them and it passed.

Selected floor: `87999900000000000` wei from OpenSea’s fresh verified-collection stats. The artifact includes both API attempts, contract scope, listing/events API 401 limitations, and RPC block-pin corroboration. Validation passed: `check-answer.mjs` printed `ok`.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH), and `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check, so the notes report no sales rather than inventing any. - **OpenSea:** the v2 stats endpoint for slug `otherdeed-expanded` returned HTTP 200 at about 2026-09-21 20:57 UTC. It gave `total.floor_price` 0.0879999 with symbol ETH. It supplied no `last_updated` time. - **CoinGecko:** `api.coingecko.com/api/v3/nfts/otherdeed-expanded` returned HTTP 200 with a floor of 0.088 ETH, which is a rounded value. The two floors differ by about 0.0001%, well under the 1% threshold. - **Contract:** CoinGecko lists `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum, and I found no shared-contract or token-id restriction. - **Selection:** I used the OpenSea figure, since the request's floor rule prefers it when the symbol is ETH and the scope matches. - **Recipe:** `panel`, with the OpenSea stats URL as `source`. - **Sales cross-check:** I did not fetch receipts or decode Seaport `OrderFulfilled` events for blocks 26021223–26028369. I did not call an RPC at all, so I never confirmed the closing block hash on-chain; the window is copied from `oracle.json`.

I wrote `artifacts/answer.json` with a floor of 87999900000000000 wei (0.0879999 ETH), and `check-answer.mjs` prints `ok`. The onchain sales cross-check the task asked for was not done. - **OpenSea:** the stats endpoint for slug `otherdeed-expanded` returned HTTP 200 without a key, at 2026-09-21T20:57:50Z. The floor was 0.0879999 in ETH, and it supplied no last-updated time. The collection endpoint confirmed the name, Otherdeed Expanded, and the slug. - **CoinGecko:** the API returned HTTP 429 (rate limited, no key available). So there is no second floor to compare, and no percentage difference to report. - **Selection:** OpenSea was used because the request's floor rule prefers it when the symbol is ETH. The recipe is a `panel` recipe citing the OpenSea stats URL. - **Not verified:** I did not check the mainnet contract address or any token-id restrictions onchain. I did not fetch the latest sales or decode any receipts in blocks 26021223 to 26028369. OpenSea's stats show 22 sales in the last day, but I didn't look at them. The notes in the answer state all of this.

I wrote `artifacts/answer.json` with a floor of **87999900000000000 wei** (0.0879999 ETH), and `check-answer.mjs` prints `ok`. The on-chain sales cross-check the question asks for is not done. - **OpenSea:** `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats` returned HTTP 200 with no credentials. `total.floor_price` was 0.0879999 in ETH, and I used it because the floor rule prefers OpenSea. The response carried no timestamp. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` also returned HTTP 200. It gave contract `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum and a floor of 0.088 ETH, again with no timestamp. The gap to OpenSea is about 0.0001%, which looks like CoinGecko rounding. - **Recipe:** `panel`, with the OpenSea stats URL as the source. Retrieval time was 2026-09-21T20:55Z. The notes in the file state the gaps. I didn't retrieve any sales or receipts from the pinned block window, so nothing was decoded from Seaport events. I also didn't confirm the OpenSea slug through contract links, or check for token-id restrictions beyond CoinGecko's single contract address.

I wrote `artifacts/answer.json` with a floor of **87999900000000000 wei** (0.0879999 ETH). `check-answer.mjs` prints `ok`. - **Source used:** OpenSea returned HTTP 200 without a key at `https://api.opensea.io/api/v2/collections/otherdeed-expanded/stats`, retrieved 2026-09-21T20:54Z. It reports `total.floor_price` 0.0879999 with symbol ETH, which the floor rule prefers. It supplied no last-updated time. The recipe is a `panel` recipe citing that URL. - **CoinGecko cross-check:** `https://api.coingecko.com/api/v3/nfts/otherdeed-expanded` also returned HTTP 200. It lists contract `0x790b2cf29ed4f310bf7641f013c65d4560d28371` on Ethereum and a floor of 0.088 ETH, about 0.0001% higher than OpenSea's, which is rounding. - **Not done:** I did not fetch or decode the latest sales' receipts (Seaport `OrderFulfilled`) in the pinned block window. I also did not check the OpenSea slug against the contract beyond the slug matching and the two floors agreeing. Both gaps are stated in `notes`. - **Fix during checking:** the checker rejected my first draft because the `window` keys were in the wrong order. I reordered them to match `oracle.json`.
