Answer this question about chain 1 over blocks 26007133 to 26021469, exactly as .imd/reads/oracle.json pins it: Which address received the most Parallel Alpha token units (ERC-1155 TransferSingle) on Ethereum mainnet in the last 48 hours? Write only artifacts/answer.json: the typed answer (address[]) and the recipe that reproduces it.
VERDICT: paths and tree verified; no suite was run for this kind of work
I wrote `artifacts/answer.json`. The address that received the most Parallel Alpha units in blocks 26007133 to 26021469 is `0x58a34dea44fa893444e1a8483636e89ddfcbb52d`, with 13 units. - **Tie:** `0x72919e83afd6cb328e6182314373b830b828fac9` also received 13. Ties break by ascending address, so `0x58a3…` comes first. - **Scan:** I read every `TransferSingle` log for `0x76be3b62873462d2142405439777e971754e8e77` in the pinned range and summed `value` by the indexed `to` address. There were 72 logs, and the file lists the top five. - **Cross-check:** Three independent public endpoints returned identical rankings: `rpc.mevblocker.io/fast`, `one.valve.city/rpc/vk_demo/evm/1` and the nodereal endpoint. Each reported chain id 1 and closing hash `0x90af93d0…42a7`. `ethereum-rpc.publicnode.com` refused the archive log query and `rpc.flashbots.net/fast` timed out, so neither is in the cross-check. - **Recipe:** The recipe is `log-rank`, grouped by `to`, summing `value`, with `topN` 5. Every open definition is stated in `definitions`, and the endpoints are named in `notes`. The file is valid JSON, and it is untracked. I did not commit anything.
Created `artifacts/answer.json` with the typed answer and reproducible recipe. Winner: `0x58a34dea44fa893444e1a8483636e89ddfcbb52d`, receiving **13 units**, selected by the required tie-break. Verified matching logs and rankings across two public RPC operators and validated the JSON.

The answer is valid JSON and matches the required shape. Summary: I scanned `TransferSingle` logs from the Parallel Alpha ERC-1155 contract (`0x76be3b62873462d2142405439777e971754e8e77`) over the pinned block range [26007133, 26021469] using two independent public RPC endpoints (`rpc.mevblocker.io` and `one.valve.city`), both of which confirmed `chainId=1` and the pinned block hash. Both returned identical results: 72 `TransferSingle` logs, with `0x58a34dea44fa893444e1a8483636e89ddfcbb52d` receiving the most units (13), tied with `0x72919e83afd6cb328e6182314373b830b828fac9` (also 13) and broken by ascending-address tie rule. Wrote `artifacts/answer.json` with the top-10 ranking, recipe (`log-rank`), definitions, and notes documenting endpoints used and two that were dropped (publicnode required an archive token; flashbots refused all `eth_getLogs` ranges).
Done. `artifacts/answer.json` is written (untracked, not committed — `git status` shows it clean because artifacts/ is ignored, so the daemon will pick it up). **Answer:** `0x58a34dea44fa893444e1a8483636e89ddfcbb52d`, with 13 Parallel Alpha token units received via `TransferSingle` over blocks 26007133–26021469. **How it was computed** - `eth_getLogs` on `0x76be3b62873462d2142405439777e971754e8e77`, topic0 = `TransferSingle`, in 2000-block chunks; deduplicated by (txHash, logIndex); grouped by the indexed `to`, summing `value`. 72 logs, 26 distinct recipients. - Each endpoint was checked for `eth_chainId == 1` and the pinned closing hash at block 26021469 before scanning. - Three independent operators returned identical logs and rankings: mevblocker, valve.city, nodereal. Flashbots, publicnode, drpc, bloxroute, 1rpc, cloudflare, blastapi and merkle all failed on `eth_getLogs` for one reason or another; these are named in `notes` as not used. **One thing worth flagging:** the top two recipients tie at 13 units (`0x58a34dea…` and `0x72919e83…`). The brief's `selection` definition breaks ties by lowercase address ascending, which puts `0x58a34dea…` first — that's what the recipe (`log-rank`, ties by key ascending) yields as well, so the deployer's rerun should land on the same order. Third place is well behind at 7 units. **Recipe:** `log-rank` over the contract with `groupBy: to`, `sumArg: value`, `topN: 10` (well beyond `head: 1`). The brief's definitions are copied verbatim, plus one I added: all ERC-1155 token ids are summed together without weighting by id, which is what "raw TransferSingle.value units" implies.
