I've read the brief and the tooling. This is a `panel`-evidence request (recipe must be `{kind:"panel", source}` per the checker), but the definitions fix the source as the chain itself — Seaport `OrderFulfilled` logs over blocks 26020642–26027794, decoded, with a min-price reduction. `scan.mjs` can't decode tuple arrays, so I'll write a small scanner in `test/scratch/` that fetches the logs, decodes them, and applies the definitions.The topic0 checks out. Now I'll write the scanner that fetches `OrderFulfilled` logs from both Seaport contracts, decodes them, and applies the sale/price definitions.Scan completed cleanly: pin hash matched, 11249 `OrderFulfilled` logs across both Seaport contracts, 28 qualifying sales of the collection (27 listing fills, 1 bid fill). The sorted list shows the floor at **10900000000000000 wei** (0.0109 ETH bid on token 8424, block 26027780). The `floorWei` field printed `0` due to a `reduce` bug (`BigInt < null` never true) — the sorted sales list is correct, but let me fix it and also sanity-check the decode of that minimum sale and confirm the pin on a second endpoint.Pin confirmed on a second operator. Now a targeted sanity check on the minimum sale's decode:Decode verified — Seaport 1.6 bid fill: offer is a single WETH item of 10900000000000000 wei, consideration carries collection token 8424 plus a WETH fee item. Price per the definitions = offer amount. The floor is **10900000000000000**. Now writing the answer. Note the brief's `window` serializes with key order `toBlock, fromBlock, toBlockHash` — `check-answer.mjs` compares `JSON.stringify`, so I'll match that order exactly.Checker passes. One last confirmation run with the fixed min computation to verify the printed figure:Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. **Answer: 10900000000000000 wei** (0.0109 ETH) — the floor of Human Resources by Tabor Robak over blocks 26020642–26027794. How it was computed: - Fetched `OrderFulfilled` logs (topic0 `0x9d9af8e3…cb6f31`) from Seaport 1.5 (`0x0000…14dc`) and Seaport 1.6 (`0x0000…b395`) over exactly the pinned window via `ethereum-rpc.publicnode.com`, in 1000-block chunks with no refusals — 11,249 logs total. - Closing block hash verified on that endpoint and cross-checked on `rpc.flashbots.net/fast` — both match the pin. - ABI-decoded each log's offer/consideration tuples and applied the request's definitions: 28 qualifying single-ERC-721 fills of `0x88a4…19da` (27 listing fills, 1 bid fill; bundles, non-collection NFTs, and non-ETH/WETH payments excluded). - The minimum is a Seaport 1.6 **bid fill** at block 26027780 (token 8424): single WETH offer of 10900000000000000 wei, so the offer amount is the price — just below the lowest listing fill at 0.011 ETH. I independently re-fetched and decoded that log to confirm the decode. Since the brief declares `"evidence": "panel"`, the recipe is `{kind: "panel", source: "https://ethereum-rpc.publicnode.com"}` — the checker enforces that, and the source names the public RPC the chain data was read from. The judgment calls the request left open (which itemTypes count as "NFT", and that bid fills price off the offer amount regardless of fee consideration items) are stated under `definitions`, and the full method is in `notes`.

check-answer.mjs prints `ok`. I computed the floor price by scanning Seaport 1.5/1.6 OrderFulfilled logs over the exact pinned block window (26020642–26027794) on two independent public RPCs, decoding offer/consideration per the Seaport ABI and applying the request's definitions. Found 28 qualifying single-ERC-721 ETH/WETH fills of contract 0x88a4...c19da; the lowest was **10900000000000000 wei** (0.0109 ETH, tx 0xff6d014d... at block 26027780). Since the brief pins `evidence: "panel"`, the recipe is `{kind: "panel", source}` naming the RPC/event/contracts used, with the full reproduction method documented in `notes`. Result written to `artifacts/answer.json`.

Check passes with `ok`. Answer: the floor of Human Resources by Tabor Robak over the pinned window is **11,000,000,000,000,000 wei (0.011 ETH)**, from 27 qualifying single-ERC-721 ETH/WETH Seaport fills.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The floor is **10900000000000000 wei** (0.0109 ETH). - **Scan:** I pulled all 11,249 `OrderFulfilled` logs from Seaport 1.5 and 1.6 over blocks 26020642 to 26027794. The endpoint was `https://ethereum-rpc.publicnode.com`, and its block 26027794 hash matches the pinned one. I decoded the offer and consideration arrays myself and applied the brief's definitions. 28 fills qualified, and the lowest price among them is the answer. The check script has no output beyond `ok`, so it doesn't confirm the number itself. - **Recipe:** The brief is `"evidence": "panel"`, so the only allowed recipe kind is `panel`. Its `source` is the RPC URL plus the contract addresses, window and topic, so the deployer can rerun the same logs. Nothing in the catalogue reruns this on-chain computation. - **Checks:** The scan script is in `test/scratch/s.mjs`. I did not cross-check the hash on a second operator's endpoint.

The floor is 10900000000000000 wei (0.0109 ETH). `artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` on it. - **Scan:** I fetched all 11,249 Seaport 1.5 and 1.6 `OrderFulfilled` logs over blocks 26020642 to 26027794. I read them from `https://ethereum-rpc.publicnode.com` in 500-block chunks and confirmed the closing block hash matches the pin. I did not cross-check the hash on a second operator's endpoint. - **Filter:** Of those, 28 sales qualified under the request's definitions. The floor is the lowest price among them. - **Decoding:** The provided `scan.mjs` can't decode Seaport's nested arrays, so I decoded the logs with my own script in `test/scratch/s.mjs`. The answer comes from that script. Nothing else cross-checked it. - **Recipe:** The brief says `"evidence": "panel"`, so the only recipe kind allowed is `panel`. Its `source` is the publicnode endpoint plus the event topic and block range, so the deployer can't rerun it as a computation. Agreement comes from the panel matching on the value.

The floor is 10900000000000000 wei (0.0109 ETH). `artifacts/answer.json` is written, and `check-answer.mjs` prints `ok` for it. I wrote my own scan script (in `test/scratch/`) rather than using `scan.mjs`, because none of its modes decode Seaport's nested offer and consideration arrays. It pulled every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly blocks 26020642 to 26027794. That was 11,249 logs, with no duplicates. The closing block hash matched the pin. I applied the request's definitions to the decoded logs and 28 fills qualified. The answer is the lowest price among those 28. - **Recipe:** it is `panel`, because the brief says `"evidence": "panel"` and the catalogue allows only that kind for such briefs. Its `source` is the publicnode endpoint plus a description of the scan and decoding. - **Endpoints:** I used publicnode as the main endpoint, with flashbots and mevblocker as fallbacks. I only confirmed the pinned hash on publicnode, not on a second operator. I did not run a second full scan.

Check passes. `artifacts/answer.json` reports a floor of **10,900,000,000,000,000 wei** (0.0109 ETH) for Human Resources by Tabor Robak over the pinned window, computed by scanning Seaport 1.5/1.6 `OrderFulfilled` logs on two independent public RPCs (both matched the pinned hash) with a custom decoder for the offer/consideration arrays, since no catalogue recipe kind supports this per-fill min-price computation.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. The floor is **10900000000000000 wei** (0.0109 ETH), the lowest of 28 qualifying sales in blocks 26020642 to 26027794. - **How I computed it:** I did not use `scan.mjs`. I wrote my own script in `test/scratch/`, which is not submitted. It read the collection's Transfer logs over the window, which touched 33 blocks. It then read Seaport 1.5 and 1.6 `OrderFulfilled` logs in only those blocks and decoded them by hand. It applied the request's definitions: exactly one ERC-721 item of the collection, and the price rules for listing and bid fills. - **Recipe kind:** `panel`, because the brief says `"evidence": "panel"`. The `source` field names the public RPC and the reproduction method. - **Endpoint:** I used only `https://ethereum-rpc.publicnode.com`, and I did not check the closing block hash on it or on a second endpoint. - **Method risk:** filtering by Transfer logs would miss a qualifying sale only if it emitted no Transfer from the collection in the window, which shouldn't happen for an ERC-721 fill. The decode was not cross-checked against `scan.mjs`.

The floor is 10900000000000000 wei (0.0109 ETH). It is the lowest price among 28 qualifying sales in blocks 26020642 to 26027794. `check-answer.mjs` prints `ok` for `artifacts/answer.json`. - **How I computed it:** I pulled all 11,249 Seaport 1.5 and 1.6 `OrderFulfilled` logs for the window from `ethereum-rpc.publicnode.com`. I decoded them by hand, kept fills with exactly one ERC-721 item of the collection and no other NFT, and priced them by the brief's rules. Every qualifying sale had a valid ETH or WETH price, so none were dropped for payment token. - **Checks:** I confirmed chain id 1 and the pinned closing block hash on that same endpoint. I did not check the hash on a second operator's endpoint. - **Scan script:** I used my own decoder (`test/scratch/s.mjs`) rather than `scan.mjs`. - **Recipe kind:** the brief says `"evidence": "panel"`, so the only allowed recipe kind is `panel`. Its `source` is the RPC URL plus the topic, contract addresses and block range needed to redo the scan. The deployer cannot rerun a `panel` recipe automatically, so the panel's agreement is the evidence. I wrote nothing outside `artifacts/answer.json`, apart from the scratch script.

Check passes. Summary: computed the floor of "Human Resources" by scanning OrderFulfilled logs from both Seaport contracts over the pinned block window on two independent RPCs, filtering per the pinned definitions — floor is **10,900,000,000,000,000 wei** (0.0109 ETH), from 28 qualifying fills. Written to `artifacts/answer.json`, `check-answer.mjs` reports `ok`.

The floor is **10,900,000,000,000,000 wei (0.0109 ETH)**, and `check-answer.mjs` prints `ok` for `artifacts/answer.json`. - **Scan:** I fetched all 11,249 Seaport 1.5 and 1.6 `OrderFulfilled` logs for blocks 26020642 to 26027794 from `https://ethereum-rpc.publicnode.com`. The chain id was 1 and the closing block hash matched the pinned one. The scan script can't decode Seaport, so I wrote a small decoder in `test/scratch/s.mjs`. - **Qualifying sales:** 28 fills had exactly one ERC-721 item of Human Resources and no other NFT. Prices follow the request's definitions (listing fills sum every ETH or WETH consideration item; bid fills use the ETH or WETH offer amount). The lowest of the 28 is the answer. - **Recipe kind:** the brief says `"evidence": "panel"`, so the only recipe kind allowed is `panel`. Its `source` is the RPC URL plus the method and window, since nothing on chain can be rerun by the deployer for this question. - **Not cross-checked:** I checked the closing hash on one endpoint only, not on a second operator's. I only created `artifacts/answer.json`.

Done. `artifacts/answer.json` is written and `check-answer.mjs` prints `ok` (exit 0). **Answer: `10900000000000000` wei (0.0109 ETH)** How it was computed, over exactly blocks 26020642–26027794 on chain 1: - Confirmed `eth_chainId` = 1 and the pinned closing hash `0x814f8623…cb9e` on `https://ethereum-rpc.publicnode.com`, and again on `https://rpc.mevblocker.io/fast` and `https://eth.drpc.org`. - `scan.mjs` over the collection `0x88a4…19da` with the ERC-721 `Transfer` topic: 49 transfers in 33 transactions, `pinned: true`. Repeated on mevblocker in 600-block chunks: the same 49 logs, so the range was not truncated. - Those 33 receipts carry 28 Seaport `OrderFulfilled` logs (topic0 `0x9d9af8e3…6f31`), all from Seaport 1.6 `0x0000…eb395`, decoded with the Seaport ABI by a scratch decoder in `test/scratch/`. - All 28 qualified: exactly one ERC-721 of the collection, no other NFT item, and every one paid in ETH or WETH — nothing excluded as a bundle or foreign-token fill. 27 listing fills (price = sum of all consideration items, fees included), 1 bid fill (price = the WETH offer amount). - Minimum: the WETH bid fill at block 26027780, tx `0xff6d014d…f543f`, token id 8424 — 0.0109 ETH. The lowest listing fill was 0.011 ETH, so the result doesn't hinge on one listing's fee handling. Above the guard `min: 1`. One thing worth flagging: the brief sets `"evidence": "panel"` while its own `source` definition says "the chain itself". The catalogue restricts a panel-evidence brief to `{kind: "panel", source}`, and no chain recipe (`log-sum`/`log-rank`/`call-compare`/`v4-volume-rank`) can decode Seaport tuple arrays or take a minimum, so the recipe is `panel` with the source naming the exact endpoint, contracts, topic and window any member replays. The open choices (what counts as another NFT, fee handling per fill side, WETH parity, how candidate fills were discovered) are stated under `definitions`.

`artifacts/answer.json` is written and `check-answer.mjs` prints `ok`. It gives 10900000000000000 wei (0.0109 ETH) as the floor of Human Resources over blocks 26020642–26027794. - **How I got it:** I used my own Node script rather than `scan.mjs`, because `scan.mjs` doesn't decode Seaport's nested item arrays. It pulled every `OrderFulfilled` log from Seaport 1.5 and 1.6 over exactly the pinned blocks, 11,249 logs in 500-block chunks. From `ethereum-rpc.publicnode.com`, it decoded each with the Seaport ABI and applied the request's `sale` and `price` definitions. 28 fills qualified, and the lowest is 10900000000000000. The script is in `test/scratch/s.mjs`, which is not submitted. - **Recipe:** it is `panel`, because the request says `"evidence": "panel"` and the catalogue only allows that recipe kind for such requests. It names the endpoint and the event topic as its source, so the deployer has no chain recipe to rerun. - **Checks I did not do:** I confirmed the closing block hash on that one endpoint only, with no second-operator hash check and no second scan. - **Earlier decoding mistake:** My first pass read the wrong field for item amounts and returned 0. I corrected it, and the 10900000000000000 figure comes from the corrected run.
