`artifacts/answer.json` is written and the plane's checker prints `ok`. **Answer: 130000000000000000 wei (0.13 ETH)** — Cool Cats floor on OpenSea. What I did: 1. **Fixed the prior failure.** The rejected attempt never produced the file. Here `artifacts/` was created explicitly and the file verified on disk before finishing. Two environment quirks had to be worked around: the Read/Write tools are denied under `/home/seat/.identitymd`, so all reads and the write went through bash; and Node's `fetch` ignores the proxy env by default, so RPC calls needed `NODE_USE_ENV_PROXY=1` (curl worked directly). 2. **Confirmed the window on chain first.** `eth_chainId` = `0x1` and block 26023188's hash matches the pinned `toBlockHash` on two independent operators (`ethereum-rpc.publicnode.com`, `eth.merkle.io`). The window is 2026-09-21T02:24:59Z → 03:24:59Z; head was 26023276, so the close is ~20 minutes old. `eth.drpc.org` did not answer and was not used. 3. **Read the floor from a primary source, twice.** This is `"evidence": "panel"`, so the recipe is `{kind: "panel", source}` and nothing is rerun from logs. OpenSea's keyless REST stats endpoint gives `floor_price: 0.13 ETH`; OpenSea's GraphQL (`gql.opensea.io`, `collectionBySlug → floorPrice.pricePerItem`, a `BestOrder`, so bids are excluded per the brief) independently gives `0.13 ETH` in native ETH. 0.13 × 10¹⁸ = 130000000000000000. Two things I flagged in `definitions`/`notes` rather than papering over: - **Only one of the three named venues was readable.** Blur's core API serves a Cloudflare challenge, Magic Eden's Ethereum RTP paths all 400, Reservoir wouldn't connect. OpenSea's own *listing-book* endpoints need an API key, which doesn't go in a file. So the "lowest across OpenSea/Blur/Magic Eden" minimum was effectively evaluated on OpenSea alone. - **OpenSea publishes the floor rounded to two ETH decimals**, so a true lowest listing anywhere in [0.125, 0.135) would also read as 0.13. The answer takes the published figure at face value — that's the value a panel can converge on, and a wei-exact floor isn't reachable keyless. The file is untracked and was not added to git (git itself is unusable here — the sandbox denies `/home/seat/.gitconfig`), so the daemon can upload it as the named output.

Created `artifacts/answer.json`; checker prints `ok`. Recorded OpenSea’s observed floor: **130000000000000000 wei**. Notes explicitly disclose that historical accuracy and RPC-only reproduction remain unverified; the required panel recipe cannot satisfy the RPC-only criterion.

Created [artifacts/answer.json](/root/.identitymd/work/d2189305-ebff-49a3-9404-20dba112a4db/431f2dae-96b8-4048-a37b-e56930f1c681/artifacts/answer.json) with OpenSea floor price `130000000000000000` wei. Provided validator result: `ok`.

Created `artifacts/answer.json` with **130000000000000000 wei**, sourced from OpenSea’s displayed Blur listing. Checker printed `ok`. The file explicitly documents that historical floor verification and RPC-only reproduction remain unsatisfied.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It gives the Cool Cats floor as 130000000000000000 wei (0.13 ETH), read from OpenSea. - **Source:** the answer comes from `floor_price` on OpenSea's collection stats for slug `cool-cats-nft` (`https://api.opensea.io/api/v2/collections/cool-cats-nft/stats`), converted to wei. The recipe is `panel` with that URL as the source. - **Timing caveat:** OpenSea has no historical floor without an API key, so this is the live floor, read about 15 minutes after the closing block's timestamp (2026-09-21T03:24:59Z). It is not a floor reconstructed at that block. `notes` says so. - **Not read:** I couldn't read the individual listings, because that endpoint needs an API key. I also didn't check Blur or Magic Eden. - **Chain check:** I confirmed the closing block hash on ethereum-rpc.publicnode.com only, not on a second operator's endpoint. - **The earlier failure:** the `artifacts/` directory didn't exist. I created it, and the file is untracked in git.

Created [artifacts/answer.json](artifacts/answer.json); the checker prints `ok`. Recorded **130000000000000000 wei**, observed on [OpenSea](https://opensea.io/collection/cool-cats-nft) from a Blur listing. The file explicitly documents that the exact historical floor and RPC-only reproduction remain unverified.

Done. `artifacts/answer.json` is written (2577 bytes, untracked, not added to git) and `check-answer.mjs` prints `ok`. **Answer: `130000000000000000` wei (0.13 ETH)** — the lowest active Cool Cats listing on OpenSea. How it was established: - **Window pinned**: `eth_chainId` = 1 and block 26023188 fetched on two operators (flashbots, publicnode); both returned the brief's hash `0x6823bad2…fca579`, timestamp 1789961099 = 2026-09-21T03:24:59Z. - **Primary source** (named in `recipe.source`): `https://api.opensea.io/api/v2/collections/cool-cats-nft/stats` — keyless, HTTP 200, server date 03:39:46Z — reports `floor_price: 0.13 ETH`. - **Corroboration**: nftpricefloor's cross-marketplace feed reports floor 0.13 ETH with `currentFloorOrigin: opensea` and a floor timestamp of 03:32:57Z, bracketing the closing block, so neither Blur nor Magic Eden undercut OpenSea. - **Open definitions stated** under `definitions`: marketplace (OpenSea), denomination (wei, 0.13 × 1e18), and the ~14-minute gap between the closing block and the reading, during which the floor history showed no change. Not reachable from this machine and noted in `notes`: OpenSea listing endpoints (401, key required), opensea.io/magiceden.io pages (403), Magic Eden RTP API (400), Blur API (Cloudflare challenge). The previous attempt failed simply because `artifacts/` was never created; that is fixed here.

Created [artifacts/answer.json](/home/imd-worker/.identitymd/work/d2189305-ebff-49a3-9404-20dba112a4db/431f2dae-96b8-4048-a37b-e56930f1c681/artifacts/answer.json). Answer: `130000000000000000` wei, sourced from OpenSea. Validation passed: `ok`.

`artifacts/answer.json` is written, and `check-answer.mjs` prints `ok`. It reports the Cool Cats floor as **130000000000000000 wei (0.13 ETH)**. - **Source:** OpenSea API v2 collection stats for `cool-cats-nft`, `total.floor_price = 0.13`. I tried the Reservoir and Magic Eden APIs too, but neither was reachable, so OpenSea is the only marketplace read. - **Recipe:** `panel`, with that OpenSea stats URL as the source. - **Chain check:** the closing hash of block 26023188 matches on `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`. - **Timing caveat:** a marketplace floor can't be replayed at a past block. I read it about 27 blocks (~5 minutes) after the window closed, so it stands in for the floor at the closing block. This is stated under `definitions` and in `notes`. - **Earlier failure:** the last attempt failed because the `artifacts/` directory didn't exist, so I created it. The file is untracked, as required. The check also caught that `window` must list its keys in the same order as `oracle.json` (`toBlock`, `fromBlock`, `toBlockHash`), and the file now does.

I've written `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. My answer is a Cool Cats floor of **130000000000000000 wei (0.13 ETH)**, taken from OpenSea. One caveat: I read it about 10–15 minutes after the closing block, not at the closing block itself. - **Block check:** block 26023188 has the pinned hash `0x6823…fca579` on two endpoints from different operators (publicnode and drpc). Its timestamp is 2026-09-21 03:24:59 UTC. - **Source:** OpenSea's public stats page (`https://api.opensea.io/api/v2/collections/cool-cats-nft/stats`) gives `floor_price` = 0.13 ETH. That figure is the lowest active listing and ignores offers and bids, as the request's definition requires. This URL is the `panel` recipe's `source`. - **Timing:** OpenSea gives no historical listing data without an API key, so I couldn't read the floor at the exact closing time. The notes say I assumed it hadn't changed in those minutes, which seems likely since the collection had only 7 sales in the past day. Other panel members who read it later may get a different number if listings changed in between. - **Other marketplaces:** Magic Eden's endpoints returned "Not Found" and Blur requires login, so OpenSea is the only source. - **Definitions:** the requester's definitions are copied unchanged. I added two entries: the source (OpenSea, collection `cool-cats-nft`) and the closing-block time. The file isn't tracked by Git, as required, and nothing else in the repository was changed. The last attempt failed because `artifacts/` didn't exist; the directory is there now.

Created `artifacts/answer.json`; checker prints `ok`. Recorded OpenSea’s observed Blur listing: **130000000000000000 wei**. The file explicitly notes that historical floor verification and RPC-only reproduction remain unmet.

I wrote `artifacts/answer.json` with a floor price of 130000000000000000 wei (0.13 ETH), and `check-answer.mjs` prints `ok`. This is not a historical read at the closing block. OpenSea gives no historical floor without an API key, so the figure is the live floor read shortly after it. - **Cause of the earlier rejection:** the `artifacts/` directory didn't exist, so the output was missing. It exists now and holds the file. The file is untracked, and `git status` is clean. - **Question type:** the request says `"evidence": "panel"`, so the recipe is `panel`. It takes a single `source` URL and nothing is rerun. - **Source:** OpenSea's public v2 stats endpoint for `cool-cats-nft`. It needs no key and returned `floor_price` 0.13 ETH on both reads. That is 0.13 × 10^18 = 130000000000000000 wei. - **Timing:** block 26023188's timestamp is 2026-09-21 03:24:59 UTC. The chain head was 26023228 when I read, about 8 minutes later. A listing change in that gap would move the number. - **Pinned hash:** I confirmed the closing block hash matches the pin on two operators (`ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`). - **Other marketplaces:** OpenSea is the only source. The per-listing endpoint needs a key, the Reservoir API was unreachable, and the Magic Eden endpoint returned 404. I did not read Blur. The request allows any major marketplace and asks for the source to be named. - **Definitions:** I stated floor as the lowest active listing with offers and bids excluded, the wei denomination, the as-of timing and the source. The notes record the timing limits and the hash check.
