Answer this question about chain 1 over blocks 26019681 to 26021472, exactly as .imd/reads/oracle.json pins it: How much IMX, in base units with 18 decimals, was transferred on Ethereum mainnet in the last 6 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
Created `artifacts/answer.json` with the reproducible recipe. Answer: **1436937905876079888991221 IMX base units**, verified against 181 matching transfer logs from two independent RPC operators.
Created [artifacts/answer.json](artifacts/answer.json) with the typed answer and reproducible recipe. Total: **1436937905876079888991221** IMX base units. Validated JSON and matched all 181 transfer logs across two independent public RPC operators.
Answer written to `artifacts/answer.json`: IMX Transfer volume over blocks 26019681–26021472 is **1,436,937,905,876,079,888,991,221** base units (181 Transfer logs), computed via `log-sum` on the IMX contract and cross-checked identically across two independently-operated public RPCs (Public Node and MEV Blocker), both confirming the pinned closing block hash. A third endpoint (flashbots.net/fast) was tried but rejected `eth_getLogs` entirely for this chain range, so it was dropped per the rotation rules.
Created `artifacts/answer.json` with total **1436937905876079888991221** IMX base units and the reproducible `log-sum` recipe. Verified all 181 logs against two independent public RPC endpoints. JSON and pinned request fields validated.

Done. `artifacts/answer.json` is written. **Answer: `1436937905876079888991221`** base units (≈ 1,436,937.906 IMX). **How it was computed** - `eth_getLogs` for `Transfer` (topic0 `0xddf252ad…3b3ef`) on `0xf57e7e7c23978c3caec3c3548e3d615c346e79ff`, over the pinned inclusive range 26019681–26021472 (1792 blocks), summing each log's 32-byte data word as a BigInt. - **181** Transfer logs across **138** distinct blocks. - Window timestamps 1789918787 → 1789940387 = exactly 21600 s, matching the "last 6 hours" in the question. **Cross-checks** - All six mainnet endpoints returned `eth_chainId` `0x1` and the pinned closing hash `0xbffd6862…2333` before any scanning. - Three independent operators — publicnode (chunk 128), valve.city (chunk 64), nodereal (chunk 256) — returned identical log count, distinct-block count and sum. Differing chunk sizes were deliberate: a silently truncated response on one endpoint would have surfaced as a disagreement. - flashbots and mevblocker served the block header but refused `eth_getLogs` with `-32602 block range extends beyond current head block` (lagging log backend), so they were dropped and not counted. - Contract identity confirmed at the closing block: symbol `IMX`, decimals 18, totalSupply 2e27. - No log had a non-standard topic layout, foreign address, out-of-range block, or `removed` flag; nothing was skipped or hand-corrected. **Recipe** is `log-sum` with exactly `address`, `event`, `sumArg`, `abs` (false — `value` is unsigned, so abs and plain sum coincide; stated to pin the reduction). Definitions record the open choices the request left: gross rather than netted, mints and burns included, no address excluded, de-duplication by `(blockHash, logIndex)`, and no decimal scaling. A local acceptance check confirms requestId, chain, window and closing hash are copied exactly from `.imd/reads/oracle.json`, the answer is a decimal string, the recipe carries only catalogue parameters, and addresses/hashes are lowercase. Scratch work is in `test/scratch/`; nothing outside `artifacts/answer.json` was created in a submitted path, and no files were added to Git.
`artifacts/answer.json` is written and is valid JSON. The answer is **1436937905876079888991221** raw IMX units, about 1,436,937.9 IMX. - **Method:** I summed `Transfer.value` over all 181 `Transfer` logs from the IMX contract (`0xf57e…79ff`). The range was blocks 26019681 to 26021472, both inclusive. - **Endpoints:** Two independent public endpoints gave the same count and sum: `ethereum-rpc.publicnode.com` and the nodereal endpoint. On both, chain id is 1 and block 26021472 has the pinned hash `0xbffd…2333`. I also started a third scan on `rpc.flashbots.net/fast`, but it was too slow and I abandoned it. - **Recipe:** `log-sum` with `sumArg: "value"` and `abs: false`, matching the request's definitions. Nothing was left open. - **Files:** `artifacts/answer.json` is untracked, and I created nothing else outside `test/scratch/`.
