`artifacts/` is ignored by the repo's own exclude rules, so the file stays untracked for the daemon to pick up, and nothing was committed. ## Done **Answer:** `59999000000000000` wei (0.059999 ETH) — written to `artifacts/answer.json`, `check-answer.mjs` prints `ok`. **What I did** - Confirmed the pinned window on two independent operators (`rpc.flashbots.net/fast`, `ethereum-rpc.publicnode.com`): block 26023188 hash matches the brief, timestamp 2026-09-21T03:24:59Z. - Read the floor from OpenSea's public collection stats endpoint (`/api/v2/collections/sappy-seals/stats`, `total.floor_price = 0.059999 ETH`) at 03:53Z, ~28 minutes after the closing block, stable across two reads. - Recipe is `{ kind: "panel", source: "https://api.opensea.io/api/v2/collections/sappy-seals/stats" }` as the brief's `"evidence": "panel"` requires. **Caveats, stated in `definitions`/`notes`** - OpenSea is the only major marketplace answering without a key: OpenSea's listings endpoint needs an API key (401), Magic Eden's Ethereum RTP paths returned 400, and Blur is behind a bot challenge (403). So the source is single-marketplace, which the definition allows ("a major marketplace"). - OpenSea reports the floor as a 6-decimal float; I assumed 0.059999 is the exact listing price rather than a rounded one. The read is ~28 minutes after the closing block, not at it — the closest an off-chain listing source permits. The previous attempt failed on an environment fault (`spawn git ENOENT`), not on content; `git` is on the PATH this run and nothing in the deliverable depends on it.

Created `artifacts/answer.json`; checker prints `ok`. OpenSea’s observed floor: **59999000000000000 wei**. The file documents that exact historical verification and RPC-only reproduction remain unsatisfied.

I wrote `artifacts/answer.json` with a floor of 59999000000000000 wei (0.059999 ETH), and `check-answer.mjs` prints `ok`. - **Source:** the OpenSea collection page, https://opensea.io/collection/sappy-seals. Its floor and best listing are both 0.059999 ETH (about $159.95). The next listing is 0.06 ETH. - **Offers:** the top offer of 0.0545 WETH is ignored, as the definition requires. - **Recipe:** `panel` with that URL as the source, since this is an off-chain fact. - **Timing gap:** I read the page about 30 minutes after the closing block's timestamp (2026-09-21 03:25 UTC), so the floor may have moved slightly since then. I couldn't read the floor as of the closing block itself. - **Other marketplaces:** the OpenSea v2 API needs a key. Blur and Magic Eden weren't reachable without one, so I used OpenSea alone. - **Chain check:** I confirmed the closing block hash on `ethereum-rpc.publicnode.com`. `notes` and `definitions` in the file record all of this. The file is untracked, as required.

I wrote `artifacts/answer.json`. It gives the Sappy Seals floor as **59999000000000000 wei (0.059999 ETH)**, taken from OpenSea, and the checker script prints `ok`. - **Source:** the recipe is a `panel` recipe pointing at `https://api.opensea.io/api/v2/collections/sappy-seals/stats`. That page gives `floor_price = 0.059999` ETH, which is OpenSea's lowest active listing. Multiplying by 1e18 gives the wei value. - **Window:** I confirmed the closing block 26023188 and its pinned hash `0x6823bad2…fca579` on `https://ethereum-rpc.publicnode.com`. Its timestamp is 1789961099. The request ID, chain and window are copied exactly from the request file, and its two definitions (floor and wei denomination) are repeated, plus a note on the source and conversion. **Limits, also stated in `notes`:** - **Timing:** the OpenSea figure is a live reading taken about 22 minutes (roughly 108 blocks) after the closing block, not a historical one at that exact time. Trading was slow (28 sales in the previous day), so I assumed the floor didn't change in between. I did not prove that. - **Other marketplaces:** Magic Eden's public API returned "Not Found" and Blur has no public API, so I couldn't check whether either had a lower listing. The answer is OpenSea's floor only. - **Listing check:** OpenSea's per-listing endpoint needs an API key, so I couldn't look at the individual cheapest listing directly.

I wrote `artifacts/answer.json` with a floor of 59999000000000000 wei (0.059999 ETH). It is the current OpenSea floor, not the floor as of the pinned window. `check-answer.mjs` prints `ok` for it. - **Source:** OpenSea API v2, `https://api.opensea.io/api/v2/collections/sappy-seals/stats`, field `total.floor_price`. The recipe is `panel`, with that URL as the source. - **Definitions:** the floor is the lowest active listing on OpenSea, with offers and bids excluded. The denomination is wei of ETH. - **Timing problem:** the pinned window (blocks 26022889–26023188) is ahead of the chain head my RPC reported today. `ethereum-rpc.publicnode.com` was at block 25826176, so I couldn't confirm the pinned closing hash. OpenSea also only serves the live floor, not a historical one. - **Other marketplaces:** I only read OpenSea, not Blur or Magic Eden. I put the timing caveat in `notes`. The file is untracked and nothing else in the repo changed.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok` (exit 0). It stays untracked — `git status` is clean. **Answer: 59999000000000 wei** (0.059999 ETH), floor of Sappy Seals on OpenSea. What I did: - **Pinned the window.** `scan.mjs --pin` on `ethereum-rpc.publicnode.com` returned `chainId 1`, `pinned: true` for block 26023188 → `0x6823bad…fca579`, and 17 Sappy Seals `Transfer` logs across the 300-block range. Cross-checked the same closing hash on a second operator, `rpc.flashbots.net/fast`. Closing block timestamp is 2026-09-21T03:24:59Z; chain head was ~97 blocks later, so the orderbook read (03:39–03:46Z) is contemporaneous with the window. - **Read the floor.** `https://api.opensea.io/api/v2/collections/sappy-seals/stats` answers without a key: `total.floor_price = 0.059999`, symbol ETH. Corroborated at the same value by CoinGecko's NFT contract endpoint and Alchemy's `getFloorPrice` (`retrievedAt 2026-09-21T03:45:25Z`) — independent readers of the same OpenSea orderbook, not independent orderbooks. - **Recipe.** The brief sets `"evidence": "panel"`, and the checker rejects any chain recipe for such a brief, so it's `{ kind: "panel", source: "https://api.opensea.io/api/v2/collections/sappy-seals/stats" }`. This is the honest shape regardless: an OpenSea listing is an off-chain signed Seaport order, so no catalogue recipe over RPC data can reproduce a floor price. I said so in `notes` rather than fabricating an on-chain proxy. Two caveats, both stated in `definitions` and `notes`: - **Blur and Magic Eden were unreadable** from this machine (Blur: Cloudflare 403; Magic Eden's EVM Reservoir path: HTTP 400 on every form I tried). So this is OpenSea's floor, named as such — not a verified minimum across all three allowed marketplaces. If either had a lower active listing, the figure is high. - **Precision.** OpenSea's keyless stats endpoint reports six fractional ETH digits; no public keyless source exposes the raw Seaport consideration in wei. 0.059999 × 10¹⁸ is exact if the listing is a whole number of microether, which a hand-entered price is.

Created `artifacts/answer.json`: **59999000000000000 wei**, observed on OpenSea. Checker printed `ok`. The file documents that historical accuracy and RPC-only reproduction could not be established.

Created [artifacts/answer.json](artifacts/answer.json) with OpenSea’s observed floor: **59999000000000000 wei**. Checker prints `ok`. The file documents that historical validity at the pinned block and RPC-only reproduction remain unverified.

I wrote `artifacts/answer.json` with a Sappy Seals floor of **59999000000000000 wei** (0.059999 ETH). `check-answer.mjs` prints `ok`. - **Source:** OpenSea's public collection stats endpoint, `https://api.opensea.io/api/v2/collections/sappy-seals/stats`, field `total.floor_price`. I checked that the `sappy-seals` slug maps to contract `0x364c828e…` on Ethereum. - **Recipe:** `panel`, since this is an off-chain fact. The block window, hash and request id are copied from the brief. - **Timing gap:** I read the floor at about 03:39 UTC on 2026-09-21, when the chain head (block ~26023260) was a few dozen blocks past the pinned closing block 26023188. This is live data, not a snapshot at the pinned block, so the floor may have moved slightly since then. The notes say so. - **Listing not inspected:** I couldn't see the underlying lowest listing, because OpenSea's listings endpoint needs an API key. The figure is OpenSea's own reported floor. I used only OpenSea, not Blur or Magic Eden. `artifacts/answer.json` is untracked, as required.

Created `artifacts/answer.json`: **59999000000000000 wei**, sourced from OpenSea. Checker prints `ok`. The file documents the unresolved limitation: marketplace listings cannot be reproduced from public RPC alone, and the historical floor is not independently proven.

Created `artifacts/answer.json` with OpenSea’s observed floor: **59999000000000000 wei**. Checker printed `ok`. The file explicitly records that historical accuracy at the pinned block and RPC-only reproduction remain unverified; those acceptance criteria are not satisfied.

I wrote `artifacts/answer.json` with a floor price of **59999000000000000 wei** (0.059999 ETH) for Sappy Seals. The checker prints `ok`, and the file is untracked. - **Source:** OpenSea's public collection stats endpoint, `https://api.opensea.io/api/v2/collections/sappy-seals/stats`. It returned `floor_price` 0.059999 ETH on two consecutive requests. - **Recipe:** `panel` with that URL as the source, since the brief marks this as an off-chain fact. - **Window:** I confirmed chain id 1 and the closing hash `0x6823bad2…a579` for block 26023188 on two operators, Flashbots and PublicNode. That block was only about 7 minutes old when I read the source, so the live floor stands in for the state at the closing block. - **Marketplaces:** I could only read OpenSea. The Blur API and Reservoir were unreachable, and Magic Eden's endpoint returned 400. OpenSea's per-listing endpoint needs an API key, so I did not check the floor against an individual listing. If Blur has a lower listing, this figure would be too high. `notes` and `definitions` in the file state all of this.

The artifact explicitly notes the unmet criterion: this listing does not prove the historical floor, and the required panel recipe cannot reproduce it from RPC data alone.
