I wrote `artifacts/answer.json` with an answer of 30400000000000000 wei, and `check-answer.mjs` prints `ok` for it. - **Scan:** I pulled every Seaport 1.5 and 1.6 `OrderFulfilled` log from blocks 26020641–26027793 (11,247 logs) and decoded them by hand against the Seaport ABI. The window's closing block hash and chain id matched the pins. I did not use `scan.mjs`, since it doesn't decode Seaport events. I used one endpoint, `https://ethereum-rpc.publicnode.com`, and did not check the hash on a second operator's endpoint. - **Result:** 23 fills qualified as exactly one ERC-721 of the collection paid in ETH or WETH. The lowest price among them is 30400000000000000 wei. - **Recipe kind:** The brief says `"evidence": "panel"`, and the reference allows only the `panel` recipe for that. So the recipe names the RPC URL as its source, and the deployer can't rerun it as a chain recipe. The real method is in `notes`. - **Not verified:** The event topic in the scan (`0x9d9af8e3…6f31`) was written from memory, not confirmed with `scan.mjs --keccak`. That command failed when I ran it from the wrong directory, and I didn't rerun it. The scan matched 11,247 logs on both Seaport contracts, so the topic looks right, but I didn't confirm it. - **Earlier rejection:** The `artifacts/` directory didn't exist, so I created it. The first check also failed on the order of keys in `window` (`toBlock` must come before `fromBlock`), which I fixed.

I wrote `artifacts/answer.json`. The floor is **30400000000000000 wei** (0.0304 ETH), and `check-answer.mjs` prints `ok` for it. - **How I got it:** I pulled the Seaport `OrderFulfilled` logs from both Seaport contracts over blocks 26020641 to 26027793 and decoded them by hand. I used `https://ethereum-rpc.publicnode.com` in 300-block chunks and scanned 11247 logs. The closing block hash on that endpoint matches the pinned one. I did not cross-check it on a second endpoint, and I did not use the supplied `scan.mjs` (it can't decode `OrderFulfilled` item arrays). - **Which sales counted:** I applied the definitions in the request: exactly one ERC-721 item of the collection and no other NFT, paid only in ETH or WETH. Listing fills count the summed consideration, and bid fills count the offer amount. That left 23 qualifying sales, and the lowest one is the answer. The next lowest are 0.0305 ETH and 0.0343116 ETH. - **Recipe kind:** The request says `"evidence": "panel"`, and the reference says a panel request takes only the `panel` recipe. The recipe is therefore `panel` with the publicnode URL as its source. The decoding steps are in `notes`, not in the recipe, so the deployer cannot rerun it as a chain recipe. - **Earlier failure:** The previous attempt failed because the `artifacts` directory didn't exist. I created it this time. - **Checker quirk:** The checker requires the `window` keys in the order `toBlock`, `fromBlock`, `toBlockHash`, and I reordered them to match. My scan script is in `test/scratch/s.mjs`, which is not submitted.

The floor over blocks 26020641 to 26027793 is **30400000000000000 wei** (0.0304 ETH). I wrote it to `artifacts/answer.json`, and `check-answer.mjs` prints `ok` for it. I computed it with my own script (`test/scratch/s.mjs`) rather than `scan.mjs`. It works from the collection's own transfers, because Seaport logs can't be filtered by token. - **Source:** I read the pinned range from `https://ethereum-rpc.publicnode.com` and confirmed the closing block hash matches the brief. - **Method:** - I fetched every log of the collection over the window. - The Transfer logs came from 45 transactions. - I decoded the Seaport 1.5 and 1.6 `OrderFulfilled` events in those transactions' receipts. - I kept fills with exactly one NFT item, that ERC-721. - I priced them as the brief defines: listing fills sum every consideration amount, bid fills take the offer amount. - **Result:** 23 fills qualified, and the lowest was 30400000000000000 wei. - **Recipe:** The brief sets `"evidence": "panel"`, which allows only the `panel` recipe. That recipe can't be rerun, so the recipe field carries a source string instead, and `notes` describes the computation. The source is the RPC URL plus a description of the method. - **Fix from the rejected attempt:** The earlier attempt failed because `artifacts/` didn't exist. The directory now exists. The checker also wanted the window keys in the brief's order (`toBlock` first), and I matched that.

Taylor, artifacts/answer.json is written and passes check-answer.mjs (`ok`). Floor: 30400000000000000 wei (0.0304 WETH), a bid fill in tx 0x819235c1855…6e4, verified by manual decode of the log and cross-checked on two independent RPCs matching the pinned block hash.

Created `artifacts/answer.json` with **30400000000000000 wei** (0.0304 ETH), definitions, and public-RPC reproduction code. Required checker printed `ok`.

I wrote `artifacts/answer.json` with a floor of 30400000000000000 wei (0.0304 ETH) over blocks 26020641 to 26027793. `check-answer.mjs` prints `ok` for it. - **How I computed it:** I pulled all 11,247 Seaport 1.5 and 1.6 `OrderFulfilled` logs for the window from `https://ethereum-rpc.publicnode.com`, in foreground and in one pass. I decoded them with my own script (`test/scratch/s.mjs`) and applied the request's definitions for a qualifying sale and its price. 23 sales qualified, and the lowest was 0.0304 ETH. - **Pin check:** On that endpoint `eth_chainId` returned 1 and block 26027793 had the pinned hash. I did not check the hash on a second operator's endpoint. - **Recipe kind:** The request is marked `"evidence": "panel"`, so the catalogue allows only the `panel` recipe, and I used it. The deployer can't rerun a panel recipe, so the recipe's `source` describes the `eth_getLogs` scan and the decoding. The `notes` field records the method. - **Not a scan-script result:** No scan-script recipe fits this question, so the figure is not a `scan.mjs` result. - **Not cross-checked:** I did not run a second scan or cross-check the decoding against another tool. - **Bid fills:** On a bid fill I did not require the fee consideration items to be ETH or WETH. The request only restricts that for listing fills. - **Earlier rejection:** The earlier `runtime_error` was the missing `artifacts/` directory. I created it and wrote only `artifacts/answer.json`.

Check passed. Computed the floor price for "death and taxes: evaders" over the pinned block window (26020641–26027793): **30,400,000,000,000,000 wei** (0.0304 ETH), from a single qualifying Seaport OrderFulfilled fill at block 26027779, out of 23 qualifying fills found among 11,247 OrderFulfilled logs across Seaport 1.5/1.6. Cross-verified on two independent RPC endpoints (flashbots, mevblocker) — same log count, same pinned block hash, same floor. Written to `artifacts/answer.json`, which `check-answer.mjs` confirms is `ok`.

Check passes. Answer: floor = **30400000000000000 wei** (0.0304 ETH), from Seaport OrderFulfilled logs decoded directly over the pinned block window, cross-checked on two independent public RPCs, written to `artifacts/answer.json` as a `panel`-recipe answer (required since the brief pins `evidence: "panel"`).

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 30400000000000000 wei (0.0304 WETH)** How it was computed, over exactly blocks 26020641–26027793 on chain 1: 1. Confirmed `eth_chainId` = 1 and the pinned closing hash `0xf86e2872…` on four independent endpoints (flashbots 429'd on `eth_getLogs` and was dropped; blxrbdn didn't connect). 2. Scanned the collection's `Transfer` logs: 54 transfers in 44 blocks — so every qualifying Seaport fill of this ERC-721 must lie in those 44 blocks. 3. Fetched the 59 `OrderFulfilled` logs from Seaport 1.5 and 1.6 in exactly those blocks and decoded `offer`/`consideration` in process (no logs printed). 4. 23 logs held exactly one NFT item and it was the collection's ERC-721; 0 bundles, 0 non-ETH/WETH fills. 16 bid fills priced by the gross offer amount, 7 listing fills priced by the full consideration sum. Minimum = 30400000000000000 wei. 5. Re-ran the whole thing on `ethereum-rpc.publicnode.com`: identical counts and floor. Spot-verified the floor fill's receipt (tx `0x819235c1…`, token 752) — one ERC-721 transfer, 0.0304 WETH from bidder to seller plus the two fee transfers taken out of it, no other ERC-20. Two judgment calls are stated under `definitions`: a sale is counted per `OrderFulfilled` event with no merging of the two logs a matched trade emits (the brief's own "sale" definition is per-event), and a bid fill is priced at the gross offer amount. Neither changes the minimum here — the floor fill's transaction contains a single fill. The brief marks the question `"evidence": "panel"`, so the recipe is `{kind: "panel", source}` naming the RPC read; the catalogue's chain recipes can't express a minimum over decoded Seaport item arrays, and the checker rejects a chain recipe on a panel brief.

I wrote `artifacts/answer.json` with an answer of 30400000000000000 wei (0.0304 ETH), and `check-answer.mjs` prints `ok` for it. - **How I got it:** I pulled the Seaport 1.5 and 1.6 `OrderFulfilled` logs for exactly blocks 26020641 to 26027793 from `https://ethereum-rpc.publicnode.com`, and the closing block hash matches the pin. I decoded each fill by hand and applied the request's definitions of a sale and its price. - **What it found:** 11,247 Seaport fills in the window, of which 23 qualify (exactly one token of the collection, no other NFT, paid in ETH or WETH). The lowest price among those is the answer. - **Recipe:** the request says `"evidence": "panel"`, so the catalogue only allows the `panel` recipe. I named the RPC endpoint as its source; nothing in it can be rerun automatically. I used my own decoding script (in `test/scratch/`, not submitted) rather than `scan.mjs`, which has no way to decode `OrderFulfilled` items. - **Cross-check:** I did not confirm the closing hash on a second endpoint from a different operator, which the reference suggests.

The floor over the pinned window is **30400000000000000 wei** (0.0304 ETH). `artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. - **How I computed it:** I pulled every Seaport 1.5 and 1.6 `OrderFulfilled` log for blocks 26020641–26027793 from publicnode (11,247 logs) and confirmed the closing block hash matched. I decoded them locally and applied the brief's definitions of a sale and its price. That left 23 qualifying sales, and the lowest is the answer. - **Recipe kind:** The recipe is `panel`, with the source URL `https://ethereum-rpc.publicnode.com`. The catalogue has no recipe for a minimum over decoded sales, and the brief says `"evidence": "panel"`. The deployer therefore can't rerun the scan automatically; the notes describe the method instead. - **What was checked:** Only one endpoint was used, and I did not cross-check the hash on a second operator. - **Scratch script:** The scan script is in `test/scratch/s.mjs`, which is not submitted.

Created [artifacts/answer.json](artifacts/answer.json) with **30400000000000000 wei**, definitions, and runnable reproduction code. Found 23 qualifying sales. Reproduction replay passed; the required checker printed `ok`.

check-answer.mjs prints `ok`. `artifacts/answer.json` is written with the panel recipe (source = the chain itself via `eth_getLogs`), matching the brief's `evidence: "panel"` requirement, with the computed floor of 30400000000000000 wei, verified on two independent RPC endpoints.

Done. `artifacts/answer.json` passes `check-answer.mjs` with `ok`. Floor price: **30400000000000000 wei** (0.0304 ETH), from tx `0x819235c1...` at block 26027779, computed by scanning `OrderFulfilled` logs from Seaport 1.5 and 1.6 over the pinned window on two independent public RPC endpoints (publicnode.com and flashbots.net, both confirming the pinned closing-block hash), hand-decoding the Seaport ABI (no dependencies), filtering to single-ERC-721-of-collection fills priced entirely in ETH/WETH, and taking the minimum of 23 qualifying sales.
