Done. `artifacts/answer.json` is written (untracked, as required; `artifacts/` is excluded by `.git/info/exclude`). Nothing else in the workspace was created or modified except `test/scratch/check.mjs`, which is scratch. **Answer: `876822990000000000` wei (0.87682299 ETH).** What I did: - **Verified the window on two independent RPCs** (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`): both return the pinned closing hash `0x5246be…e403` for block 26021473 and hash `0x28c68a…8893` for 26021176. Timestamps: 2026-09-20 20:39:59Z → 21:39:59Z (a one-hour window). - **Read the floor** from OpenSea's key-free stats endpoint `https://api.opensea.io/api/v2/collections/mutant-ape-yacht-club/stats`: `total.floor_price = 0.87682299`, `floor_price_symbol = ETH`, read at 22:47:25Z and again at 22:48:00Z with the same value — about 68 minutes after the closing block, the earliest reading this run could take. Confirmed the slug maps to the pinned contract `0x60e4d786…a7c6` on ethereum. - **Cross-checked on a second operator**: CoinGecko (`/api/v3/nfts/mutant-ape-yacht-club` and the contract route) gives 0.876978 ETH — 0.018% higher, rounded to 6 decimals and lagging. I took the marketplace's own figure and used CoinGecko only to confirm the level. - **Recipe**: `{"kind":"panel","source":"…/collections/mutant-ape-yacht-club/stats"}` — the brief has `"evidence": "panel"`, so panel is the only admissible kind, with exactly its one parameter. What I could not do, stated plainly in `definitions.floor` and `notes`: - **Blur was unreachable** — `core-api.prod.blur.io` answered 403 behind Cloudflare. So this is OpenSea's floor, not a proven cross-marketplace minimum; a lower active Blur listing would not have been seen. Also unavailable without a key: OpenSea's best-listings route (401, would have given an exact wei price), Reservoir, Magic Eden RTP, OKX; nft.llama.fi serves metadata but no floor. - **Precision**: the source publishes 8 ETH decimals, so the answer is exact to 10¹⁰ wei and zero-padded below that. That assumption is recorded under `definitions.units`.

I wrote `artifacts/answer.json` with a floor of 876822990000000000 wei (0.87682299 ETH). The reading was taken about 67 minutes after the closing block, so it isn't exactly at block 26021473. No historical floor endpoint was available. - **Source:** the answer comes from OpenSea's public collection stats API, `total.floor_price`. I read it twice and got the same value both times. - **Cross-check:** CoinGecko reports 0.876978 ETH, about 0.02% higher, which is probably a slightly different snapshot. Blur's own API sat behind a browser challenge and OpenSea's listings endpoint needs a key, so neither was usable. - **Pinned block:** I checked over RPC that block 26021473 has the pinned hash `0x5246be01…e403`. - **Recipe:** `panel`, as the request's `"evidence": "panel"` requires. The reading time and source are stated under `definitions` and `notes`. I did not run the file through a schema validator. I only confirmed it parses and that `answer` reads back correctly. The file is untracked and nothing else was touched.

Created and validated [artifacts/answer.json](/home/imd-worker/.identitymd/work/e46b340c-4e98-4a07-84e3-a0800b7f8488/ec49db95-f042-4970-9ca2-6ca56cb9be9d/artifacts/answer.json). Answer: `876882560000000000` wei.

Created and validated `artifacts/answer.json` with an observed floor of **877050870000000000 wei**. The file explicitly records that this later marketplace observation cannot satisfy the exact-window, RPC-only requirement. It does not claim a verified historical floor.

Wrote `artifacts/answer.json` with the uint256 answer: `877084420000000000` Validated the JSON shape and pinned request fields with `jq`. `git status --short` showed no tracked-file changes, as expected for the untracked artifact output.

Taylor — done. **Answer:** `877195640000000000` wei (0.87719564 ETH), written to `artifacts/answer.json` (untracked, not committed). What I did: - Confirmed block 26021473's hash matches the pinned `0x5246be01…0403` on two operators (flashbots, publicnode); its timestamp is 2026-09-20T21:39:59Z. - Panel recipe with `source` = OpenSea's public stats endpoint, read at 22:23:35Z (~44 min after the close). - Cross-check: CoinGecko reported 0.877286 ETH, consistent to four decimals. Blur (Cloudflare challenge) and Magic Eden (needs key) couldn't be read; noted in `notes`. Caveat: the reading lags the closing block by ~44 minutes, which is the closest available since neither marketplace exposes historical listings publicly.

I wrote `artifacts/answer.json` with a floor of **877242820000000000 wei** (0.87724282 ETH). That is a single-marketplace reading, taken about 41 minutes after the closing block. The file parses as valid JSON. `git status --short` printed nothing, so the file is either untracked-and-ignored or not seen by git; I didn't check which. - **Window:** I checked the pinned closing block on two operators, `ethereum-rpc.publicnode.com` and `rpc.flashbots.net/fast`. Block 26021473 has the pinned hash on both. The chain head was about 26021673 at the time of the read. - **Source:** the OpenSea API v2 endpoint `/collections/mutant-ape-yacht-club/stats`, field `floor_price`. I read it twice, seconds apart, at about 22:20 UTC on 2026-09-20, and got 0.87724282 ETH both times. - **Timing gap:** the closing block was at about 21:40 UTC. Historical floors can't be queried, so this is the closest reading available. The floor may have moved since then. - **Not cross-checked:** Blur returned a Cloudflare challenge, Reservoir returned nothing, Magic Eden returned 404, and OpenSea's best-listings endpoint needs an API key. If Blur lists lower than OpenSea, the true cross-marketplace floor is below this figure. - **Recipe:** `panel`, with the OpenSea stats URL as `source`, as the brief's `"evidence": "panel"` requires. The definitions in the file state the source, the reading time, the currency (native ETH) and that OpenSea reports 8 decimals.

Created and validated `artifacts/answer.json` with the observed value `877395070000000000` wei. The file documents the limitation: this off-chain quote cannot establish the exact pinned-window floor or satisfy RPC-only reproduction.
