Created and validated [artifacts/answer.json](/home/imd-worker/.identitymd/work/bdb3b451-cf78-40ac-afbd-ee150095abe3/af01edaa-5c90-4702-be99-483deac41356/artifacts/answer.json). Answer: `6649000000000000000` wei.

Created `artifacts/answer.json` with observed floor **6649950000000000000 wei** and passed JSON validation. The artifact explicitly marks this as partial: the off-chain observation cannot establish the pinned historical floor or satisfy RPC-only reproduction.

I wrote `artifacts/answer.json` with a BAYC floor of **6649954999000000000 wei**, which is 6.649954999 ETH. The file parses as valid JSON. It is untracked, as required. - **Source:** I read `total.floor_price` from OpenSea's public collection stats endpoint. It returned the same value on two calls. - **Cross-check:** CoinGecko's NFT endpoint showed a floor of 6.65 ETH at the same time, which is consistent. - **Chain check:** I confirmed the pinned closing hash for block 26021473 on two independent RPCs, `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`. - **Recipe:** `panel`, with the OpenSea stats URL as its source, since the brief says `"evidence": "panel"`. - **Timing gap:** The APIs only serve the current floor, not a historical one. My reading was at 22:14 UTC on 2026-09-20, about 35 minutes after the closing block (21:39:59 UTC). The floor may have moved slightly in that gap. This and the reading time are stated under `definitions` and `notes`. - **Blur:** I did not get a Blur reading, because its API needs authentication. The floor therefore reflects OpenSea's listings only. - **Rounding:** Panel members who round to 6.65 ETH would land on a different wei value than this nine-decimal figure.

Done. `artifacts/answer.json` is written (untracked, not committed) and validates against the request. **Answer: `6649954999000000000` wei** (6.649954999 ETH) — BAYC floor, `panel` recipe with source `https://api.opensea.io/api/v2/collections/boredapeyachtclub/stats`. How it was established: - **Window verified** on two operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`): chain id 1, block 26021473 hash matches the pinned `0x5246be…e403`, timestamp 2026-09-20 21:39:59 UTC. Head was ~140 blocks past the close, so the readings were as close as the sources allow (~20–30 min after). - **OpenSea stats API**: floor 6.649954999 ETH at 22:08Z and again 22:10Z (no key needed). - **Alchemy getFloorPrice** (aggregator): same 6.649954999 ETH, retrieved 22:09:09Z. - **NFTPriceFloor** (aggregator watching OpenSea and Blur): 6.649954999 ETH, origin OpenSea, token #3519, at 22:00:11Z — meaning Blur had no lower listing. - **CoinGecko**: 6.65 ETH (2-dp rounding, consistent). Caveats stated in `definitions`/`notes`: Blur's API is behind a Cloudflare challenge and OpenSea's per-listing endpoints require an API key, so the wei figure is the exact conversion of OpenSea's 10-significant-digit float; and no source provides per-block floor history, so the assumption is the floor did not move in the ~25 minutes between the close and the readings (it was stable across all reads).

Created `artifacts/answer.json` with observed value `6649954999000000000` wei. JSON, uint256 encoding, and request pins validated. The file documents that the pinned-window floor remains unverified and RPC-only reproduction could not be satisfied.

I wrote `artifacts/answer.json` with a floor of **6649954999000000000 wei** (6.649954999 ETH). It is a live reading taken about 13 minutes after the closing block, not a historical floor at block 26021473. - **Source:** OpenSea's public collection stats endpoint, `https://api.opensea.io/api/v2/collections/boredapeyachtclub/stats`, field `total.floor_price`. Three reads a few seconds apart gave the same value. - **Timing:** I read it at about 21:53 UTC on 2026-09-20. The closing block's timestamp is 21:39:59 UTC, and the chain head was only about 60 blocks past it. The floor could differ slightly from what it was at the closing block. - **Cross-check:** CoinGecko's NFT API reports 6.65 ETH, which is consistent to its two-decimal rounding. - **Not read:** Blur blocked the request with a bot challenge, and Reservoir was unreachable. There is no direct Blur reading, and `notes` says so. - **Chain check:** I confirmed the closing block hash matches the pinned one on two independent Ethereum RPC operators, `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`. - **Recipe:** `panel`, with the OpenSea URL as its `source`, since the brief marks this as an off-chain panel question. - **Definitions:** `definitions` states the floor source, the wei conversion, the collection contract and the reading time. - **Git:** the file is untracked and nothing else in the repo changed. I didn't run any tests beyond loading the file back and printing the answer. I didn't check it against a schema.

Created `artifacts/answer.json` with the observed OpenSea floor: **6649954999000000000 wei**. Validated JSON and pinned metadata. The artifact documents that historical cross-market accuracy and RPC-only reproduction cannot be established; those acceptance criteria remain unmet.
