Check passes. `artifacts/answer.json` reports the Opepen Edition floor as 94905000000000000 wei (0.094905 ETH), sourced from OpenSea's public stats API, with the pinned block hash confirmed against `ethereum-rpc.publicnode.com`.

Check passes. `artifacts/answer.json` is written: Opepen Edition floor price 0.094905 ETH → 94905000000000000 wei, sourced from OpenSea's public stats API, cross-checked against the OpenSea collection page, with the pinned closing block hash independently verified via public RPC.

The required checker prints `ok`. The request specifies OpenSea listing data as panel evidence. Those listings are off chain, so the stated RPC-only reproduction criterion cannot be met for this question.

I wrote `artifacts/answer.json` with a floor price of 94905000000000000 wei (0.094905 ETH). This is a live reading, not the price at the pinned closing block. `check-answer.mjs` prints `ok` for the file. - **Source:** OpenSea's public stats endpoint for `opepen-edition`, `total.floor_price`, which needed no API key. It only returns the current value, so I couldn't get the price as of the closing block's timestamp. The `time` definition and `notes` in the file say so. - **Recipe:** `panel` with that URL as the source, since the request is marked `"evidence": "panel"`. - **Not done:** I didn't use the scan script or check the closing block hash on an RPC, since nothing in this answer is computed from chain logs.

I'll read the remaining provided inputs and check the environment.This is a panel-evidence question — I need the OpenSea floor price of Opepen Edition at the pinned closing block's timestamp, in wei, and a `panel` recipe with a source URL. Let me invoke the imd-rpc skill and get the block's timestamp.The pinned block (26041705) is ~22 blocks behind head — essentially "now". Let me check what scan.mjs offers and get the block's timestamp.Now I need the closing block's timestamp and the OpenSea floor. First, the block timestamp — I'll grab `eth_getBlockByNumber` once and confirm the pin.OpenSea API works without a key, and the collection is confirmed (`opepen-edition`, verified, contract `0x6339e5e072086621540d0362c4e3cea0d643e114`). Now the floor:Floor from stats: 0.094905 ETH. The best-listings response was tiny — let me look at it and try the `all` listings endpoint.Stats floor reads 0.094905 ETH. The listings endpoints need a key, so let me cross-check the exact listing price via Alchemy's public demo NFT endpoint, which reports per-marketplace floors.Both sources agree: OpenSea floor = 0.094905 ETH = 94905000000000000 wei, retrieved minutes after the pinned block (timestamp 1790184995 ≈ 17:36:35 UTC). Writing the answer — note the checker string-compares `window`, so I must preserve the brief's exact key order (`toBlock`, `fromBlock`, `toBlockHash`).Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 94905000000000000 wei** (0.094905 ETH) How it was pinned and read: - **Pin confirmed**: `eth_getBlockByNumber(26041705)` on `ethereum-rpc.publicnode.com` returned the exact pinned hash `0xc20d4f80...a8f806`, timestamp `1790184995` (2026-09-23 17:36:35 UTC — ~5 min before the read). - **Collection**: OpenSea slug `opepen-edition`, `safelist_status: verified`, contract `0x6339e5e072086621540d0362c4e3cea0d643e114` (Jack Butcher's collection). - **Floor**: `https://api.opensea.io/api/v2/collections/opepen-edition/stats` reports `floor_price = 0.094905 ETH`. Cross-checked via Alchemy's public `getFloorPrice`, which independently reports `openSea.floorPrice = 0.094905 ETH` at 17:42 UTC. - **Recipe**: `{ kind: "panel", source: <opensea stats URL> }` — the only recipe kind a `"evidence": "panel"` brief accepts. One caveat noted in `notes`: OpenSea's listings endpoints require an API key, so the stats endpoint's `floor_price` is the primary read; it matched the second source exactly.

I wrote `artifacts/answer.json` with an answer of **94911000000000000 wei (0.094911 ETH)**, and `check-answer.mjs` prints `ok`. But this number isn't a direct OpenSea reading, which is what the request's definition of "floor" asks for. - **Why not OpenSea:** OpenSea's API now needs a key. Both ways to get a free one without signing up (their key endpoint and their MCP server) returned "429 Too Many Requests", with a retry wait of about 36 minutes. The opensea.io collection page is built in the browser, so the downloaded page has no floor price in it. - **What I used instead:** CoinGecko's NFT endpoint for the Opepen Edition contract (`0x6339e5e072086621540d0362c4e3cea0d643e114`). It gave a floor of 0.094911 ETH, read about 6 minutes after the closing block (block time 17:36:35 UTC). This is CoinGecko's marketplace-wide floor rounded to 6 decimals, so it may not match OpenSea's exact lowest listing to the wei. Members who read OpenSea directly may land on a slightly different number. - **Pinned block:** the closing block's hash matches the pin on publicnode's endpoint. - **In the file:** the recipe is a `panel` recipe with the CoinGecko URL as its source. The collection, how the floor was read and when are stated under `definitions`, and `notes` explain the fallback. To get a true OpenSea figure, rerun the read once OpenSea's key limit resets, from `api.opensea.io/api/v2/listings/collection/opepenedition/best`, and replace the answer and source.

check-answer.mjs prints `ok`. The answer is written to `artifacts/answer.json`: Opepen Edition floor price of 0.094906 ETH (94906000000000000 wei), sourced from OpenSea's public stats API as a panel-evidence recipe.

check-answer.mjs prints `ok`. artifacts/answer.json is written with the panel recipe citing OpenSea's stats endpoint (floor 0.094906 ETH = 94906000000000000 wei), confirmed against the pinned block's timestamp/hash.

Check passes. Wrote `artifacts/answer.json` with the Opepen Edition floor price (0.094906 ETH = 94906000000000000 wei) sourced from OpenSea's API, cross-referenced against the pinned block's timestamp (essentially now), using a `panel` recipe.

`artifacts/answer.json` is written and passes `check-answer.mjs`. It's a panel recipe citing OpenSea's collection stats API: floor price 0.094906 ETH → 94906000000000000 wei for Opepen Edition (contract `0x6339e5e072086621540d0362c4e3cea0d643e114`, verified on OpenSea), read as close as possible to the pinned closing block's timestamp.

The check passed with `ok`. `artifacts/answer.json` is written with the floor price of Opepen Edition (0.094906 ETH → 94906000000000000 wei) as a panel-evidence answer, sourced from OpenSea's stats API, with the pinned block hash confirmed against public RPC.

Check passes with `ok`. `artifacts/answer.json` is written with the panel recipe pointing at OpenSea's stats endpoint, floor price 0.094906 ETH converted to `94906000000000000` wei, and the closing block's timestamp confirmed against a public RPC.

Check passes with `ok`. Wrote `artifacts/answer.json`: floor price of Opepen Edition = 0.094906 ETH = 94906000000000000 wei, sourced from OpenSea's collection stats API (`floor_price` field), with a `panel` recipe pointing to the public OpenSea endpoint.

Check passes. Wrote `artifacts/answer.json`: Opepen Edition floor price at block 26041705 (pinned window, hash confirmed) is 0.094906 ETH = **94906000000000000 wei**, sourced live from OpenSea's collection stats API (panel recipe, since the block's timestamp is effectively the current moment).

Check passes with `ok`. Wrote `artifacts/answer.json`: floor price of Opepen Edition = 0.094906 ETH = 94906000000000000 wei, sourced live from OpenSea's collection stats API (panel evidence, since the pinned block's timestamp is essentially the present moment).

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok` for it. - **Source:** OpenSea's v2 stats endpoint for the `opepen-edition` collection, `total.floor_price`. The recipe is `panel` with that URL as the source. - **Timing:** OpenSea has no historical floor, so this is the live value. I read it when the chain head was block 26041721, about 16 blocks (a few minutes) after the pinned closing block 26041705. If the floor moved in that gap, the answer is off by that move. The `notes` and `definitions` fields say this. - **Hash check:** I did not confirm the pinned closing hash on a second endpoint. I only used publicnode, which I queried for the block number and timestamp; I did not compare the hash it returned against the pinned one.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH). The answer check prints `ok`. - **Source:** the number is `total.floor_price` from OpenSea's v2 stats endpoint for the `opepen-edition` collection. The recipe is `panel`, as this brief requires, with that URL as its source. - **Timing:** this is a live read, not a historical one. I took it about 3 minutes after the pinned block, since OpenSea gives no way to read a past floor. The endpoint's `floor_price` field is a single figure. I did not check whether it counts only ETH/WETH listings, and I did not look at individual listings. - **Pinned block:** I confirmed block 26041705 on publicnode and its hash matches the one in `oracle.json`. I did not cross-check on a second endpoint. - **Not run:** I skipped the scan script, since this is an off-chain question and nothing gets rerun.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok`. The catch is that this is today's floor, not the floor at block 26041705. - **Source:** the `floor_price` field from OpenSea's stats endpoint for the `opepen-edition` collection. The recipe is `panel`, with that URL as its source. - **Timing gap:** OpenSea doesn't expose historical floors, so I couldn't read the floor at the pinned closing block. `definitions` and `notes` both say so. - **Hash not verified:** the public RPC I queried (publicnode) returned null for block 26041705, so I couldn't confirm the pinned hash. I did not try a second endpoint. - **Collection not cross-checked:** I used the `opepen-edition` slug without checking it against other collections sharing the name.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok`. That figure is the live OpenSea floor, not the floor at the pinned closing block. I read `total.floor_price` from the OpenSea v2 collection stats endpoint for `opepen-edition` and multiplied by 1e18. That endpoint only gives the current value, so I couldn't retrieve the floor as of the block 26041705 timestamp. The `time` definition and `notes` in the file say this. The recipe is kind `panel` with that endpoint as its `source`, as the brief's `"evidence": "panel"` requires. No chain scan was run, since nothing here can be computed from logs. I did not check whether other collections share the name, so "verified one with the largest market cap" rests on the `opepen-edition` slug being the right one.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH). It is a live reading, not a reading at the pinned closing block. `check-answer.mjs` prints `ok` for it. I took the figure from `total.floor_price` on OpenSea's stats endpoint for `opepen-edition` and multiplied by 1e18. That endpoint gives only the current floor. The run happened long after the pinned block, so the number does not reflect the floor as of block 26041705. I stated this in `definitions.time` and `notes`. If the panel's other members read the same live value, agreement is plausible, but the answer carries no historical guarantee. The recipe is the `panel` kind, with the stats URL as its source. I also did not confirm that `opepen-edition` is the verified collection with the largest market cap, as the request's collection definition requires. I did no on-chain scan, since the request is a panel question.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH). The catch is that this is today's floor, not the floor at the pinned block. `check-answer.mjs` prints `ok`. - **Source:** the OpenSea stats endpoint for the `opepen-edition` collection, `https://api.opensea.io/api/v2/collections/opepen-edition/stats`. Its `total.floor_price` was 0.094906 ETH, which I multiplied by 1e18. - **Timing:** the endpoint returns the current floor only, so I couldn't read the floor as of the pinned closing block. I stated this under `definitions` and in `notes`. - **Recipe:** the `panel` kind, since the brief marks this as off-chain evidence. I ran no chain scan and did not check the closing block hash against an RPC. The answer file is untracked and not committed.

I wrote `artifacts/answer.json` with a floor price of 94906000000000000 wei (0.094906 ETH). `check-answer.mjs` prints `ok` for it. I read that figure from OpenSea's live stats endpoint for the `opepen-edition` slug (`total.floor_price`). It is a read from today, not a historical read at the pinned closing block, because I found no OpenSea source that serves a historical floor. The value may differ slightly from the floor at the pinned block's timestamp. `definitions` and `notes` say this. The recipe is the `panel` kind with that URL as its source. I did not run a chain scan, since the request is a panel question. The file is untracked and not committed.

I wrote `artifacts/answer.json` with a floor price of 94906000000000000 wei (0.094906 ETH), but that is the floor at the time I ran this, not at the pinned closing block. `check-answer.mjs` prints `ok` for the file. The figure comes from `total.floor_price` on the OpenSea v2 stats endpoint for the `opepen-edition` slug. I couldn't get a historical floor as of the pinned block's timestamp. The file says this under `definitions.time` and in `notes`. If the floor moved between the pinned block and now, other panel members reading the same endpoint may agree with this figure while a rerun at the pinned time would not. The recipe is the `panel` kind, with the OpenSea stats URL as its source. The check flagged the order of the keys inside `window`, and I reordered them to match `oracle.json`.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok` for it. The figure is the current floor, not the floor at the pinned closing block. I read `total.floor_price` from the OpenSea public stats endpoint for `opepen-edition` at run time. I found no way to get a historical floor as of block 26041705. The `definitions` section states this. The recipe is the `panel` kind, with the same stats URL as its source. I did not touch the chain or the scan script, since nothing about this question is rerunnable from RPC data. I did not check that this is the verified collection with the largest market cap. I assumed the `opepen-edition` slug is the official one.

I wrote `artifacts/answer.json` with a floor price of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok`. - **Source:** the OpenSea API v2 stats for the `opepen-edition` collection, which reported `floor_price` of 0.094906 ETH. The recipe is the `panel` kind, since the request marks this as off-chain evidence. - **Timing:** I read the floor when the chain head was block 26041724, a few blocks after the pinned close at 26041705. OpenSea gives only the current floor, so it may have moved slightly since the pinned block. I noted that in `notes`. - **Not done:** I did not check the block hash on a second endpoint. I only read the chain head from `ethereum-rpc.publicnode.com`, to place the read in time.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok` for it. The catch is timing. I read OpenSea's live stats endpoint (`total.floor_price`) when I ran this, not the floor at block 26041705. I couldn't retrieve a historical floor. I said this in `definitions` and `notes`. The recipe is `panel` with that OpenSea stats URL as the source, since the brief is panel evidence. I ran no chain scan, so the pinned block range is copied into the answer but wasn't used to compute it.

I wrote `artifacts/answer.json` with a floor of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok` for it. The value comes from the OpenSea collection stats endpoint for the `opepen-edition` slug (`floor_price` × 1e18), fetched once with `curl`. That endpoint only gives the current floor, so this is the floor at run time, not at the pinned closing block. The brief asks for the floor as of the closing block's timestamp, and I couldn't get a historical value. The `definitions` and `notes` fields in the file say the same. The recipe is the `panel` kind, with that stats URL as its source. Nothing is rerun on chain for this question, so the answer only counts if other panel members read the same value. I did not confirm the pinned closing block's hash against an RPC endpoint. I copied it from the brief.

I wrote `artifacts/answer.json` with an answer of 94906000000000000 wei (0.094906 ETH), and `check-answer.mjs` prints `ok`. This is the live floor, not the floor at the pinned block. I read it from OpenSea's v2 collection stats endpoint (`total.floor_price` for `opepen-edition`) at run time. OpenSea has no historical floor endpoint, so I couldn't read the price at block 26041705. The `definitions` and `notes` fields in the file say this. The recipe is `panel` with that stats URL as its source, since the request pins `"evidence": "panel"`. Nothing was scanned on chain, so there was no RPC scan and no closing-hash check. One thing tripped the checker: it wants the window keys in the order `toBlock`, `fromBlock`, `toBlockHash`, matching `oracle.json`. I fixed the order and re-ran it.
