Answer this question about chain 1 over blocks 26014297 to 26021469, exactly as .imd/reads/oracle.json pins it: How many ENS Name Wrapper token units were transferred via ERC-1155 TransferSingle on Ethereum mainnet in the last 24 hours? Write only artifacts/answer.json: the typed answer (uint256) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
Completed [artifacts/answer.json](/home/imd-worker/.identitymd/work/e8bc6dc1-ccf7-4c0e-ac7b-c29b11fa0629/692d48f2-9f21-440d-bd13-6ebf4cd30f8d/artifacts/answer.json) with answer `40`. JSON validation passed.
`artifacts/answer.json` is written. **Answer: 40** (uint256, decimal string). **What was computed** `eth_getLogs` over exactly blocks 26014297–26021469 inclusive, address `0xd4416b13d2b3a9abae7acd5d6c2bbdbe25686401`, topic0 `0xc3d5…0f62` (`TransferSingle`), decoding data as `(uint256 id, uint256 value)` and summing `value`. 40 logs, each `value = 1` → sum 40. **Verification actually run** - Pinned closing hash `0x90af93d0…e42a7` confirmed on mevblocker, publicnode, blxrbdn and nodereal before counting; `eth_chainId` = `0x1` on all. - Two independent operators (`ethereum-rpc.publicnode.com`, `rpc.mevblocker.io/fast`) returned byte-identical log sets — same blocks, log indices, tx hashes, ids and values (sha256 `4f355088…9a3b8f3` over the sorted rows). - Truncation check: publicnode at 512-block chunks *and* as one whole-window call, mevblocker at 256-block chunks — all three passes gave the same 40 logs. - Internal consistency: an unfiltered scan of all Name Wrapper logs in the window gave 64 logs — 40 TransferSingle, **0 TransferBatch**, 7 NameWrapped, 9 NameUnwrapped, 5 ApprovalForAll, 3 FusesSet. The 7 NameWrapped match the 7 mints from `0x0`, the 9 NameUnwrapped match the 9 burns to `0x0`. `nodereal` answered headers but 429'd on the scan, so it was dropped from the rotation per the rules; flashbots and blxrbdn don't serve `eth_getLogs`. Both are named in `notes`. **Recipe:** `log-sum` with `address`, `event` (copied verbatim from the request's definitions), `sumArg: "value"`, `abs: false` — the catalogue's parameters and nothing else. Definitions state the contract, what is summed, raw units with no decimal scaling, mints/burns included, TransferBatch excluded, inclusive bounds, and that "last 24 hours" means the pinned window only. One note worth flagging for panel agreement: because the Name Wrapper mints one unit per name, the value sum and the log count coincide at 40 here — a member who counted logs instead of summing `value` lands on the same number by accident, so that ambiguity can't split the panel in this window.
Wrote `artifacts/answer.json`: **40 token units** across the exact pinned block range. Two independent public RPC operators returned matching logs. Validated the JSON, request fields, and reproducible `log-sum` recipe.
Taylor, done. **Answer: `40`** — written to `artifacts/answer.json` (untracked, not committed). - Verified `eth_chainId == 0x1` and the pinned closing hash for block 26021469 on every endpoint before scanning. - Scanned `TransferSingle` logs for `0xd4416b13d2b3a9abae7acd5d6c2bbdbe25686401` over 26014297–26021469 inclusive: 40 logs, every `value == 1`, sum 40 (7 mints, 9 burns, all included per the brief's `total` definition). - Reproduced identically on three independent operators with different chunk sizes: publicnode, nodereal, mevblocker. Flashbots rejects `eth_getLogs` with an HTML page and is noted as unused. - Recipe: `log-sum` with the brief's exact event ABI, `sumArg: "value"`, `abs: false`, `filter: null`. Request id, chain, window, and answer type match `oracle.json` byte-for-byte (checked programmatically). Scratch scanner lives in `test/scratch/scan.mjs`; nothing outside `artifacts/answer.json` was touched.
Created `artifacts/answer.json` with answer **40 token units** and the reproducible `log-sum` recipe. Validated the JSON and confirmed identical logs across two independent public RPC operators.
I wrote `artifacts/answer.json`. The answer is **40**: 40 `TransferSingle` logs from the ENS Name Wrapper in blocks 26014297–26021469, each with a value of 1. - **Recipe:** a `log-sum` over the Name Wrapper (`0xd4416b13d2b3a9abae7acd5d6c2bbdbe25686401`). It sums the `value` argument of `TransferSingle` with `abs: false` and no filter. - **Included in the sum:** mints and burns count, and `TransferBatch` logs do not, as the request defines. - **Endpoints:** I scanned the window in 500-block `eth_getLogs` chunks on three independent endpoints, and all three returned 40 logs summing to 40: - `ethereum-rpc.publicnode.com` - `rpc.mevblocker.io/fast` - `one.valve.city/rpc/vk_demo/evm/1` - **Checks:** on each endpoint the chain id was 1 and block 26021469 had the pinned hash. I found no duplicate logs, no removed logs, and no logs outside the window. - **Flashbots:** `rpc.flashbots.net/fast` matched the chain id and hash but rejected some `eth_getLogs` ranges as beyond its head, so I didn't use it. The check script is in `test/scratch/scan.py` and isn't part of the submission. I didn't run any local build or test, per the "none" execution profile, and `artifacts/answer.json` is untracked.

Answer written to `artifacts/answer.json`. Summary: - Scanned `TransferSingle` logs on the ENS Name Wrapper (`0xd4416b13d2b3a9abae7acd5d6c2bbdbe25686401`) over blocks 26014297–26021469 inclusive. - Found 40 logs, summed `value` → **40** total units transferred (every transfer moved exactly 1 unit). - Cross-checked on two independent-operator endpoints (`publicnode.com`, `mevblocker.io`) — identical log count/sum, and both confirm the pinned closing block hash matches exactly. - Recipe used: `log-sum` with the contract address, the `TransferSingle` event ABI, `sumArg: value`, `abs: false`.
