Top sender: `0x91d40e4818f4d4c57b4578d9eca6afc92ac8debe` Raw SAND sent: `734964420000000000000000` Two independent RPC scans matched exactly.

Done. `artifacts/answer.json` is written and untracked. **Answer:** `0x91d40e4818f4d4c57b4578d9eca6afc92ac8debe` sent the most SAND in the pinned window — 734,964,420,000,000,000,000,000 raw units (734,964.42 SAND), in a single transfer at block 26021223 to `0x611f7bf868a6212f871e89f7e44684045ddfb09d`. How it was computed: - Recipe `log-rank` over the SAND contract `0x3845bada…3903a5d0`, `Transfer(address indexed from, address indexed to, uint256 value)`, `sumArg: value`, `groupBy: from`, `topN: 5` — exactly the catalogue's parameters, nothing extra. - Scanned `eth_getLogs` over blocks 26019681–26021472 inclusive (21,600 s = the pinned 6 hours): 229 Transfer logs, 127 distinct senders. Logs deduped by `blockHash:logIndex`, `removed` dropped, every log asserted inside the window. - Cross-checked on three operators — publicnode and valve.city at 128-block chunks, nodereal at 448-block chunks — all returning identical log counts, sender counts and full ranking. Six endpoints confirmed `eth_chainId` `0x1` and the pinned closing hash for block 26021472. No request was refused or truncated, so no range needed halving. The leader's total was re-derived separately by a topic-filtered `eth_getLogs` on its `from` address. Worth flagging: the lead over the runner-up (`0x06fd4ba7…`, 716,823.69 SAND across 5 transfers) is only ~2.5%, so a panel member who truncates any part of the window can easily land on a different head. Every open definition (contract, gross-vs-net "sent", inclusive bounds, raw 18-decimal units, tie rule) is stated under `definitions` and used consistently; ranks 6–12 are in `notes` for context. A local validator (in `test/scratch/`, not submitted) checked the file's JSON shape, that `requestId`/`chainId`/`window` are byte-identical to `.imd/reads/oracle.json`, that `answer` equals the scanned top 5 and `figure` the leader's sum, and that the descending-with-ascending-address-tiebreak order holds across all 127 senders — all pass.

Created and validated `artifacts/answer.json`. Top sender: `0x91d40e4818f4d4c57b4578d9eca6afc92ac8debe` — **734,964.42 SAND**. Verified identical results from two public RPC operators over the exact pinned range.

Created [artifacts/answer.json](artifacts/answer.json) with the typed ranking, definitions, and reproducible recipe. Top sender: `0x91d40e4818f4d4c57b4578d9eca6afc92ac8debe` — **734,964.42 SAND**. Validated JSON and confirmed identical results from two independent public RPC endpoints across the exact pinned range.

The address that sent the most SAND over blocks 26019681 to 26021472 is `0x91d40e4818f4d4c57b4578d9eca6afc92ac8debe`. It sent 734,964.42 SAND, which is `734964420000000000000000` in raw 18-decimal units. I scanned SAND `Transfer` logs over the pinned range, both bounds inclusive. There were 229 logs in the window. I summed `value` per `from` address, counting burns and transfers to any address, and ranked highest first with ties broken by lowercase address ascending. I ran the scan independently on two operators, `ethereum-rpc.publicnode.com` and `eth.drpc.org`. Both reported chain id 1, both returned the pinned closing hash `0xbffd6862…a2333`, and both produced identical rankings. The runner-up is `0x06fd4ba7973a0d39a91734bbc35bc2bcaa99e3b0` at 716,823.69 SAND, about 18,141 SAND behind, so the top spot is not a near-tie. `artifacts/answer.json` is written with the request id, chain, window and hash copied from `oracle.json`, and the top five addresses in `answer`. The recipe is `log-rank` with `groupBy: from`, `sumArg: value` and `topN: 5`, and `definitions` restates the request's fixed definitions. I checked that the file parses as JSON but did not validate it against a schema. It is git-ignored, so it stays untracked as required, and I changed nothing else outside `test/scratch/`.
