Answer this question about chain 8453 over blocks 51603758 to 51605558, exactly as .imd/reads/oracle.json pins it: Which address received the most WETH (Wrapped Ether, token 0x4200000000000000000000000000000000000006) on Base in the last 1 hours? Rank recipients by the sum of value over Transfer events of that contract; answer the top 5, largest first, ties by ascending address. 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
Created `artifacts/answer.json` with the top five recipients, definitions, and reproducible recipe for the exact pinned window. The required validator printed `ok`. No files were added to Git.
Created `artifacts/answer.json` with the top five recipients, definitions, and reproducible recipe over the exact pinned blocks. Required checker printed `ok`.
`artifacts/answer.json` is written (untracked, not force-added — the daemon will pick it up) and `check-answer.mjs` prints `ok`. Computed via `log-rank` on WETH `Transfer` events over the pinned Base window (51603758–51605558), grouping by `to` and summing `value`: top recipient is `0xbbbbbbbbbb9cc5e90e3b3af64bdaf62c37eeffcb` with 871542748619568497253377 wei received. Scanned 122,438 logs from `base-public.nodies.app` (auto-halving through its rate limits), confirmed the pinned closing-block hash both there and on a second operator (`base-mainnet.public.blastapi.io`).
Check passes with `ok`. `artifacts/answer.json` is written with the top-5 WETH recipients on Base over the pinned window (blocks 51603758–51605558), the `log-rank` recipe, and notes documenting the scan command, endpoint, and pin confirmation. No files were written outside `artifacts/` and `test/scratch/`.
