I wrote `artifacts/answer.json` with a floor of **94578000000000000 wei** (0.094578 ETH), but it comes from a single marketplace, not a minimum across marketplaces. - **Source:** OpenSea's collection stats API for `otherdeed` (`https://api.opensea.io/api/v2/collections/otherdeed/stats`). The recipe is `panel`, since the brief's `evidence` is `panel`. - **Timing:** I read it at about 22:39 UTC on 2026-09-20. The closing block 26021474 has timestamp 21:40:11 UTC, so the reading is roughly an hour after it, not at the block itself. - **Missing sources:** I couldn't read Blur or any other aggregator. Blur returned a bot-challenge page, Magic Eden returned Not Found, and OpenSea's per-listing endpoint needs an API key. The definition asks for the lowest listing across marketplaces, so a cheaper Blur listing could exist. - **Chain check:** `ethereum-rpc.publicnode.com` and `eth.drpc.org` both return the pinned closing hash for block 26021474. - **Validation:** the JSON parses, and the request id, chain and window are copied from `oracle.json`. The file is untracked. The notes and definitions in the file say the same about the source and timing.

Done. `artifacts/answer.json` is written (untracked, nothing else touched). **Answer: `94578000000000000` wei** (0.094578 ETH) How I got there: **Window verified first.** Block 26021474 = `0x18d0e62` hashes to `0x57ff11be…4397` — matches the pin — on both `rpc.flashbots.net/fast` and `ethereum-rpc.publicnode.com`, `eth_chainId` `0x1` on both. Closing block timestamp 1789940411 = 2026-09-20T21:40:11Z; opening block 26021177 = 20:40:11Z, so the pin is the hour ending 21:40:11Z. **The reading.** The brief carries `"evidence": "panel"`, so the catalogue admits only the `panel` recipe: a primary off-chain read, not an on-chain reduction. OpenSea's own public v2 stats endpoint (`/api/v2/collections/otherdeed/stats`, no API key) returned `total.floor_price = 0.094578`, `floor_price_symbol = ETH`, at 2026-09-20T22:37:34Z. CoinGecko's NFT endpoint for the same contract returned the identical `0.094578` ETH — a second, independent host. The slug `otherdeed` was confirmed to resolve to exactly `0x34d85c9cdeb23fa97cb08333b511ac86e1c4e258` on Ethereum. 0.094578 × 10¹⁸ = 94578000000000000 wei exactly. **Staleness handled explicitly.** The read is 57 min after the closing block — a floor is an order-book fact with no value retrievable at a past block. To bound the drift I scanned the collection's `Transfer` logs over exactly 26021177–26021474 and over 26021475–head: **zero transfers**, confirmed on three endpoints (publicnode, nodereal, valve.city; flashbots does not serve `eth_getLogs`). No sale swept the floor during the window or before the reading, and both API readings were stable across repeats. **Two caveats, both stated in `definitions`:** - Blur's API is behind a bot wall, and Reservoir / Magic Eden / Alchemy's demo NFT endpoints all refused keyless requests, so "lowest across major marketplaces" is in practice the OpenSea figure — no lower listing was observable from any keyless public source. - OpenSea publishes six decimals. The keyed best-listings endpoint (401 without a key) would give the exact listing; the answer scales the published figure and claims no further digits. Validation script in `test/scratch/` checked all 22 shape/content assertions (request id, chain and window byte-identical to the brief, recipe restricted to `{kind, source}`, lowercase hex, decimal-string uint256) — all pass.

I wrote `artifacts/answer.json` with a floor of 94578000000000000 wei (0.094578 ETH). It comes from OpenSea only, and it was read about 55 minutes after the closing block, not at the block itself. I read `total.floor_price` from OpenSea's collection stats endpoint, `https://api.opensea.io/api/v2/collections/otherdeed/stats`. It needs no API key. Two reads a few seconds apart, at 2026-09-20T22:35Z, gave the same value. OpenSea's collection record lists this collection's contract as `0x34d85c9cdeb23fa97cb08333b511ac86e1c4e258` on Ethereum, matching the request. The file is valid JSON. Its request id, chain and window are copied from `oracle.json`. The recipe is `panel` with that URL as the source, since the brief says `"evidence": "panel"`. - **Timing:** Block 26021474 has timestamp 2026-09-20T21:40:11Z, and the chain head at reading time was about block 26021748. OpenSea's public endpoint has no historical floor. - **Sources:** The request defines the floor as the lowest listing across OpenSea, Blur and any public aggregator, but I only read OpenSea. Blur and OpenSea's listings endpoint need an API key, and Reservoir was unreachable. The floor could be lower on Blur or another aggregator. - **Chain check:** `eth_chainId` returned 1 and the block hash at 26021474 matched the pinned hash on both `https://rpc.flashbots.net/fast` and `https://ethereum-rpc.publicnode.com`. Those RPCs only confirmed the closing block, its timestamp and the head. The floor itself isn't derivable from chain data. All of this is also recorded in the `definitions` and `notes` fields of the file.

Created and validated [artifacts/answer.json](artifacts/answer.json) with observed floor **94578000000000000 wei**. The file documents the unresolved limitation: this off-chain reading cannot establish the exact pinned-window floor or satisfy RPC-only reproduction.

Verified valid JSON, and the closing block's hash/timestamp checked against a public RPC match the pin exactly. Answer written to `artifacts/answer.json`: floor price of Otherdeed for Otherside is **94,578,000,000,000,000 wei** (0.094578 ETH), read from OpenSea's public stats API and cross-checked against CoinGecko NFT and NFTPriceFloor (both independently reporting the same OpenSea-sourced figure) at 2026-09-20T22:06:24Z, ~26 minutes after the pinned closing block's timestamp. Since this is a panel/off-chain question, the recipe is `panel` citing the OpenSea endpoint as source, with the corroborating sources and reasoning in `notes`.

Created and validated `artifacts/answer.json` with **94578000000000000 wei**. The artifact documents the limitation: this is a verified marketplace observation; the pinned historical floor cannot be reproduced from public RPC data alone.

Created and validated `artifacts/answer.json`, left untracked. Recorded **94578000000000000 wei** with sources and observation time. The file explicitly documents that the pinned historical floor and RPC-only reproduction could not be verified.

Created and validated `artifacts/answer.json` with **94578000000000000 wei**, corroborated by OpenSea and CoinGecko. The artifact documents the limitation: this near-closing observation cannot establish the exact historical floor or satisfy RPC-only reproduction.
