I wrote `artifacts/answer.json` with a Beanz floor of **42997170000000000 wei** (0.04299717 ETH). The reading was taken about 40 minutes after the closing block, not at it. `git status` shows nothing tracked, so the file is untracked as required. - **Window:** I confirmed the pinned closing hash for block 26021474 on three public endpoints: publicnode, drpc and flashbots. All three returned it, and the block timestamp is 2026-09-20 21:40:11 UTC. - **Source:** the OpenSea collection page at `https://opensea.io/collection/beanzofficial`. The slug `beanz` is marked as a delisted collection; `beanzofficial` matches contract `0x306b1ea3ecdf94ab739f1910bbda052ed4a9f949`. The recipe is `panel` with that URL, since the brief says `"evidence": "panel"`. - **Value:** OpenSea's collection floor was 0.04299717 ETH in two reads about 20 seconds apart, at 22:20 UTC. The lowest of the 50 listings on the page, a Blur listing, is the same price. - **Excluded:** WETH offers at 0.04 are not listings, so I ignored them. Two limits on how far this figure can be trusted: - **Timing:** listings are off chain and there is no historical query, so 22:20 UTC was the nearest reading I could get. The page also drifted from 0.04299719 to 0.04299717 within a minute, so another panel member reading at a different moment may differ in the last digits. - **No second aggregator:** Blur's API returned a bot challenge, and OpenSea's own API, Reservoir, Alchemy and Rarible needed a key or were unreachable. The only Blur data is what OpenSea shows. I put both limits, along with the source, reading time and units, in `definitions` and `notes`.

I wrote `artifacts/answer.json` with a floor price for Beanz of **42997310000000000 wei** (0.04299731 ETH). It is a reading taken about 35 minutes after the closing block, not at the block. It comes from OpenSea only, and the file parses as valid JSON. - **Source:** the OpenSea API v2 collection stats endpoint for `beanzofficial` (`floor_price`). The recipe is `panel`, as the brief's `"evidence": "panel"` requires. - **Window check:** the closing block 26021474 has the pinned hash `0x57ff11be…e4397` on two independent RPC endpoints, publicnode and flashbots. - **Timing:** block 26021474 has timestamp 1789940411, and my reads were at about 1789942512–1789942540. The floor may have moved in between. - **Stability:** three consecutive reads gave 0.04299731 ETH. An earlier read gave 0.04299732. - **Limits:** the source rounds to 8 decimals, so the answer is only precise to 1e10 wei. - **Blur not read:** I did not read Blur or any other marketplace, because there was no public unauthenticated API. It is not a cross-marketplace floor. - **Unreconciled listing:** one early best-listing read showed a listing with seller proceeds of 0.0425683269 ETH before fees. The listings endpoint then started requiring an API key, so I could not reconcile that listing's total with the stats floor. `notes` and `definitions` in the file record all of this.

Done. `artifacts/answer.json` is written (untracked, not committed) and validated against the brief. **Answer: `42997350000000000` wei (0.04299735 ETH)** How I got there: - **Pinned block verified** on two operators (flashbots, publicnode): block 26021474 hash `0x57ff11be…4397` matches the brief; mined 2026-09-20T21:40:11Z. - **Primary source** (recipe `panel`, source `https://api.opensea.io/api/v2/collections/beanzofficial/stats`): `floor_price` = 0.04299735 ETH, identical across three reads at 22:07:59–22:08:39Z, ~28 min after the closing block. - **Cross-checks**: Alchemy's NFT API (reading OpenSea) gave 0.04299736 → 0.04299734 over a few minutes, CoinGecko 0.04299739 — the floor listing's ETH price drifts by ~1e-8 ETH/min (looks USD-denominated or descending), so OpenSea's own stable 8-decimal figure is the one reported. One caveat, stated in `notes`: Blur's API is behind a Cloudflare challenge from this machine and the other aggregators (Magic Eden, Rarible, Element, OKX, LooksRare) require keys or 404'd, so I could not confirm there is no Blur listing below OpenSea's floor.

Created and validated `artifacts/answer.json` with observed OpenSea floor **42997430000000000 wei**. The file documents the limitation: this off-chain observation cannot establish the exact historical floor or satisfy RPC-only reproduction.

Created and validated `artifacts/answer.json` with observed price **42997450000000000 wei**. The file explicitly records the limitation: historical cross-market listings cannot be reproduced from RPC alone, so the exact-window acceptance criterion remains unmet.

Taylor, done. `artifacts/answer.json` is written and validated (untracked, not committed). **Answer:** `42997500000000000` wei (0.0429975 ETH) - Closing block 26021474 hash verified on two operators (Flashbots, PublicNode); block time 2026-09-20T21:40:11Z. - Floor read from OpenSea `collections/beanzofficial/stats` at 21:49:38Z, ~9 min after the closing block; Alchemy's floor aggregator independently reported the same OpenSea figure. - Recipe: `{"kind":"panel","source":"https://api.opensea.io/api/v2/collections/beanzofficial/stats"}`. - Caveat noted in `definitions`/`notes`: Blur is behind a Cloudflare challenge and Reservoir/Magic Eden returned nothing, so a lower Blur listing couldn't be ruled out — the answer is the lowest listing among readable sources.

Created and validated `artifacts/answer.json` with observed value **42997550000000000 wei**. The file documents the limitation: the marketplace reading is after the closing block, and the requested off-chain floor cannot be reproduced from public RPC data alone.
