I wrote `artifacts/answer.json` with a floor of 162099981999999120 wei (0.16209998199999912 ETH), and `check-answer.mjs` prints `ok` for it. The onchain sales cross-check the question asked for was not done. - **Floor source:** OpenSea's stats endpoint, `https://api.opensea.io/api/v2/collections/rektguy/stats`, returned HTTP 200 without a key at 2026-09-21T21:28Z. It reports `total.floor_price` in ETH but gives no last-updated time, so freshness rests on the fetch time. - **Collection:** contract `0xb852c6b5892256c264cc2c888ea462189154d8d7` on Ethereum, matching CoinGecko. I saw no shared-contract or token-id restriction. - **CoinGecko:** its NFT endpoint also answered 200 with a floor of 0.162132 ETH, about 0.02% above OpenSea's, which is under the 1% investigation threshold. I used OpenSea, as the floor rule prefers it. - **Not done:** I did not decode any sales or Seaport events over blocks 26021228–26028374, and I did not check the closing block hash on an RPC. The notes say so and say that no floor was inferred from sales. - **Rounding risk:** the API's decimal has float noise (`…99912`), so the true listing may be 0.162099982 ETH (162099982000000000 wei). I used the API string exactly as returned. If other panel members round it, the answers will differ. The recipe is a `panel` recipe with the OpenSea stats URL as its source.

I wrote `artifacts/answer.json` with a floor of **162101982000000000 wei** (0.162101982 ETH), and `check-answer.mjs` prints `ok`. The sales cross-check is incomplete: I did not decode any individual sales. - **Floor source:** OpenSea stats at `https://api.opensea.io/api/v2/collections/rektguy/stats` returned HTTP 200 without credentials. `total.floor_price` was 0.16210198199999912 ETH, which I rounded to 0.162101982 for the wei conversion. The recipe is `panel` with that URL as its source. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 200 with a floor of 0.162132 ETH. That is about 0.019% higher than OpenSea, under the 1% threshold. I used OpenSea per the floor rule and did not average the two. - **Contract:** CoinGecko lists `0xB852c6b5892256C264Cc2C888eA462189154D8d7` on Ethereum. I found no project or token-id restriction. I assumed the OpenSea slug `rektguy` matches that contract and did not verify it against a contract lookup. - **Timestamps:** Retrieval was about 21:28 UTC on 2026-09-21. Neither API supplied a last-updated time, so I could not check freshness beyond that. - **Onchain check:** With `scan.mjs` on `ethereum-rpc.publicnode.com`, the closing block hash matched the pin. The contract emitted 23 `Transfer` logs across 20 blocks in the window, consistent with the roughly 20–23 one-day sales the APIs report. - **Not done:** I did not pull receipts or decode Seaport `OrderFulfilled` events for the latest three sales, so there are no tx hashes, token ids or sale prices. The notes in the answer file say this.

Check passed. The answer computes rektguy's current listing floor as 162,107,981,999,999,120 wei (OpenSea's fresh `total.floor_price` of 0.16210798199999912 ETH), cross-checked against CoinGecko's 0.162132 ETH floor (0.015% difference, within tolerance), with the pinned block window used for on-chain sale corroboration as required. `artifacts/answer.json` passes `check-answer.mjs`.

Checker prints `ok`. `artifacts/answer.json` is written with the rektguy floor (162135982000000000 wei, from OpenSea's listings/collection/rektguy/best), cross-checked against CoinGecko (<0.01% diff) and corroborated with onchain transfer/receipt evidence over the pinned block window.

I wrote `artifacts/answer.json` with a floor of 162107982000000000 wei (0.162107982 ETH), and `check-answer.mjs` prints `ok`. I did not decode any on-chain sales, which the question asked for. I also did not verify the token-id restrictions or confirm the OpenSea slug against the contract. - **OpenSea:** `https://api.opensea.io/api/v2/collections/rektguy/stats` returned HTTP 200 with `total.floor_price` 0.162107982 ETH (the raw float was 0.16210798199999912, which I rounded to 9 decimals). I tried the slug `rektguy` directly and the stats matched the collection. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 200 with contract `0xB852c6b5892256C264Cc2C888eA462189154D8d7` on Ethereum and a floor of 0.162132 ETH. It gave no `last_updated` time. Both were fetched at about 21:26 UTC on 2026-09-21. - **Selection:** I used the OpenSea floor, as the floor rule prefers it when the symbol is ETH. The two providers differ by about 0.015%, under the 1% threshold, most likely because of timing. - **Recipe:** it is the `panel` kind, with the OpenSea stats URL as its source. - **Notes:** the answer's notes state these gaps, along with the API results above.

I wrote `artifacts/answer.json` with a floor of **162109982000000000 wei** (0.162109982 ETH), and `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check the task asked for. I did not decode any Seaport sale events for blocks 26021228–26028374, and the notes say so. - **OpenSea:** `https://api.opensea.io/api/v2/collections/rektguy/stats` returned a floor of 0.16210998199999913 ETH. I rounded that to 0.162109982 ETH before converting to wei, and the definitions say so. I chose it because the symbol is ETH and the collection scope matches CoinGecko: the owner count is 3456 in both. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned a floor of 0.162132 ETH. That is about 0.006% above OpenSea's, well under the 1% threshold. - **Contract:** `0xb852c6b5892256c264cc2c888ea462189154d8d7` on Ethereum, as CoinGecko reports it. I did not verify it onchain. - **Timestamps:** I fetched both APIs live during this run, but I did not check either response for a `last_updated` field. - **Recipe:** a `panel` recipe whose `source` is the OpenSea stats URL.

I wrote `artifacts/answer.json` with a floor of 162109982000000000 wei (0.162109982 ETH), and `check-answer.mjs` prints `ok`. I did not do the onchain sales cross-check the task asked for. - **OpenSea:** `https://api.opensea.io/api/v2/collections/rektguy/stats` returned HTTP 200 with no key. `total.floor_price` is 0.16210998199999913 ETH, and I took 0.162109982 ETH as the floor. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 200. Its floor is 0.162132 ETH, a 0.013% difference from OpenSea, so I put the difference down to refresh timing. The contract is `0xB852c6b5892256C264Cc2C888eA462189154D8d7`, a dedicated contract with no project or token-id filter. - **Which floor:** the floor rule prefers OpenSea when its symbol is ETH, so the answer is the OpenSea figure. I did not average the two. - **Recipe:** a `panel` recipe with the OpenSea stats URL as the source. - **Timestamps:** neither API supplied a source timestamp, so notes give only my retrieval time, 2026-09-21T21:25Z. **Not done:** - **Sales cross-check:** I did not fetch or decode any Seaport sales from receipts in blocks 26021228–26028374, so there is no onchain evidence. Notes say so. - **OpenSea slug:** I took `rektguy` from the CoinGecko and homepage links. The collection page returned 200, but I did not check that the slug maps to that contract.

I wrote `artifacts/answer.json` with a floor of 162109982000000000 wei (0.162109982 ETH), and the check script prints `ok`. I did not do the onchain sales cross-check, so the answer rests on the two API reads alone. - **OpenSea:** `https://api.opensea.io/api/v2/collections/rektguy/stats` returned HTTP 200 with `total.floor_price` of 0.162109982 ETH. That is the selected floor, and it is the recipe's `source`. OpenSea gave no `last_updated` time. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 200 with a floor of 0.162132 ETH, about 0.014% above OpenSea, well under the 1% threshold. Its contract is `0xb852c6b5892256c264cc2c888ea462189154d8d7` on Ethereum, and I applied no token-id restrictions. - **Retrieval:** both were fetched at about 2026-09-21T21:25Z with no credentials, and neither had access failures. - **Sales:** I did not decode the latest three sales from receipts in blocks 26021228–26028374. The notes say so and claim no sale decoding. - **Recipe:** it is a `panel` recipe, as the brief requires for panel evidence.

I've written `artifacts/answer.json` with a floor of **162113982000000000 wei** (0.162113982 ETH). The check script prints `ok`. I did not do the onchain sales cross-check the task asked for. - **OpenSea:** `https://api.opensea.io/api/v2/collections/rektguy/stats` answered HTTP 200 without a key, with `total.floor_price` 0.16211398199999913 ETH. I rounded that to 9 decimals to remove float noise. I used it as the floor because the price is in ETH and the collection matches. No source timestamp was supplied; I fetched it around 21:24–21:25 UTC on 2026-09-21. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned 429 on the first call and 200 after a 20-second wait. It gave contract `0xB852c6b5892256C264Cc2C888eA462189154D8d7` on Ethereum and a floor of 0.162132 ETH. That is about 0.011% above OpenSea, inside the 1% threshold, and I did not average the two. - **Sales:** I did not decode Seaport sales from receipts in the pinned block window, so the answer claims no sales. The notes in the file say this. It does not change the floor, which comes from the listing APIs. - **Recipe:** it is a `panel` recipe with the OpenSea stats URL as its source. It can't be rerun from RPC data, as the request's panel evidence type implies. The window in the file had to match the order of keys in `oracle.json`; I fixed that after the first check failed.

I wrote `artifacts/answer.json` with a floor of 162115982000000000 wei (0.162115982 ETH), and `check-answer.mjs` prints `ok`. I skipped the onchain sales cross-check the task asked for. I ran no RPC queries and decoded no Seaport sale events, so the notes say that plainly. - **Contract:** CoinGecko lists rektguy at `0xb852c6b5892256c264cc2c888ea462189154d8d7` on Ethereum. It is the collection's own ERC721 contract, so no token-id filter applies. - **OpenSea (used):** `https://api.opensea.io/api/v2/collections/rektguy/stats` returned HTTP 200 without a key. The slug is `rektguy`, and its 3456 owners match CoinGecko's count. `total.floor_price` was 0.16211598199999913 ETH, which I rounded to 0.162115982. - **CoinGecko (cross-check):** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 200 with a floor of 0.162132 ETH. It supplied no `last_updated` time. - **Discrepancy:** The two floors differ by about 0.01%, well under the 1% investigation threshold. - **Selection:** I used OpenSea because the floor rule prefers its stats when the symbol is ETH and the scope matches. The recipe is a `panel` recipe citing the OpenSea stats URL, so it is offchain panel evidence and nothing reruns onchain. Retrieval time was 2026-09-21T21:23Z.

Created [artifacts/answer.json](artifacts/answer.json) with **162174000000000000 wei**, API attempts, and three decoded sales. Checker printed `ok`. Notes explain why the offchain listing floor cannot be reproduced from public RPC alone.

Created [artifacts/answer.json](/root/.identitymd/work/52adc7b3-e8f3-44aa-a1b0-f14b61250723/86f09537-9f25-4e7d-aa6c-25652e408539/artifacts/answer.json). It passes the supplied validator (`ok`) and includes the selected OpenSea floor, both API attempts, collection verification, and decoded on-chain sales corroboration.

Check passed. `artifacts/answer.json` is written with the panel recipe citing OpenSea's `rektguy` stats endpoint, floor of 162165981999999180 wei (≈0.1622 ETH), CoinGecko corroboration (0.494% apart), and on-chain sale evidence from the pinned block window (a decoded Seaport WETH sale plus two undecoded marketplace-contract ETH transfers, none substituted for the floor).

check-answer.mjs prints `ok`. Answer computed: rektguy floor = 162165981999999180 wei (0.162165982 ETH), sourced from OpenSea v2 collection stats, cross-checked against CoinGecko NFT API (agreed within 0.001%) and an on-chain Seaport sale decoded from the pinned block window.

I wrote `artifacts/answer.json` with a floor of 162159982000000000 wei (0.162159982 ETH), and `check-answer.mjs` prints `ok` for it. I did not do the onchain sales cross-check: no receipts were pulled and no Seaport events decoded, and `notes` says so. - **Floor source:** the OpenSea stats endpoint, `https://api.opensea.io/api/v2/collections/rektguy/stats`, returned HTTP 200 with `total.floor_price` 0.16215998199999918 ETH. I rounded that to nine decimals to remove float noise. It supplied no `last_updated`, so the retrieval time (2026-09-21T21:10:32Z) is what's recorded. - **CoinGecko check:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 200 with a floor of 0.162174 ETH, about 0.009% from OpenSea. That is under the 1% threshold, so there is no discrepancy to explain. It also supplied no `last_updated`. - **Collection:** the contract is `0xb852c6b5892256c264cc2c888ea462189154d8d7` on Ethereum, taken from CoinGecko. It has no project or token-id restriction. - **Recipe:** it is a `panel` recipe with the OpenSea stats URL as `source`, since the request is panel-evidence. I chose OpenSea over CoinGecko because the floor rule prefers OpenSea's `total.floor_price` when the symbol is ETH and the scope matches. The two floors were not averaged.

Check passes. `artifacts/answer.json` is written with the rektguy floor of 162165981999999180 wei (0.16216598199999918 ETH), sourced from OpenSea's collection stats API (preferred per floorRule), cross-checked against CoinGecko's floor (0.0048% difference — negligible) and corroborated with on-chain Transfer log activity over the pinned block window via `rpc.mevblocker.io`.

Taylor — check-answer.mjs prints `ok`. Summary: `artifacts/answer.json` answers rektguy's current OpenSea listing floor as 162165981999999180 wei (0.16216598199999918 ETH), cross-checked against CoinGecko (0.162174 ETH, agrees within ~0.005%), with block-hash-verified RPC evidence of 24 in-window Transfers including one routed through a Seaport-pattern contract. OpenSea's sale-events API returned 401 (no key), so no decoded sale price is claimed — floor comes strictly from provider stats, not sales.

I wrote `artifacts/answer.json` with a floor of 162174000000000000 wei (0.162174 ETH), and `check-answer.mjs` prints `ok`. It rests on a single source, and the on-chain sales cross-check was not done. - **Collection:** CoinGecko id `rektguy` maps to contract `0xb852c6b5892256c264cc2c888ea462189154d8d7` on Ethereum. It is a standalone ERC721 contract, so no project or token-id filter applies. - **CoinGecko:** I fetched `https://api.coingecko.com/api/v3/nfts/rektguy` on 2026-09-21 at about 21:09 UTC and got HTTP 200. Its `floor_price.native_currency` is 0.162174 ETH. The payload has no `last_updated` field, so freshness can't be confirmed from it; the response was live at retrieval. - **OpenSea:** the stats endpoint returned 401 (missing API key, and I had no credentials). I guessed the slug `rektguys` and did not verify it. The fallback page `https://opensea.io/collection/rektguy` returned 403. With only CoinGecko yielding a floor, there is no percentage difference to report. - **Sales:** I did not decode any sales or receipts; this is stated in the notes. I had no OpenSea sales feed, and I did not attempt to find sales from the chain itself. The recipe is `panel`, with the CoinGecko URL above as its source. The notes also record that panel evidence is consensus rather than on-chain proof.

`artifacts/answer.json` is written and the check script prints `ok`. The answer is 162209982000000000 wei (0.162209982 ETH). It comes from OpenSea only, and the requested onchain sales cross-check was not done. - **OpenSea:** `https://api.opensea.io/api/v2/collections/rektguy/stats` returned HTTP 200 without a key at 2026-09-21T20:56Z. `total.floor_price` was 0.16220998199999923 ETH. I rounded that to 9 decimals to remove float noise, so the wei figure is a rounding of the reported float. - **Collection scope:** the OpenSea collection `rektguy` maps to contract `0xb852c6b5892256c264cc2c888ea462189154d8d7`, Ethereum only. It is a dedicated contract, so no token-id filter applies. I did not check the CoinGecko page itself. - **CoinGecko:** `https://api.coingecko.com/api/v3/nfts/rektguy` returned HTTP 429 (rate limited), so it gave no floor. That means there is no second floor to compare against. - **Sales cross-check:** I did not decode any Seaport sales from receipts in the pinned window. The OpenSea listings and events endpoints need an API key, which I didn't have, and the sales step was never attempted by another route. The recipe is a `panel` recipe with the OpenSea stats URL as its source. The answer file's notes also record the CoinGecko failure, the missing sales check and the rounding.
