  "notes": "Computed from public RPC data with the supplied dependency-free scanner. Reproduction command: node .imd/reads/skills/oracle-assess/scripts/scan.mjs --rpc https://base-rpc.publicnode.com --from 51603759 --to 51605559 --pin 0x53d63b2b25661200aa9ec5991ca7d294eb857986cb648d5b5804b987b2cbf2d6 --address 0xd9aaec86b65d86f6a7b5b1b0c42ffa531710b6ca --event 'Transfer(address,address,uint256)' --rank topic:1 --by data:0 --top 5 --chunk 250 --concurrency 1. This completed in 8 nonoverlapping chunks, with 1024 distinct logs across 401 blocks and 141 sender addresses. Chain ID 8453 and the pinned closing hash matched. An initial full-range PublicNode query also returned 1024 logs; the smaller-range scan confirmed identical counts and ranking to check for a possible response cap. Totals in answer order: 3127065841, 2264046378, 2111119255, 2059888272, 1627973705. Earlier scans on https://base-public.nodies.app and https://base-mainnet.public.blastapi.io were interrupted after range and rate limits; both confirmed the chain and closing hash, and BlastAPI also confirmed these in a separate check. https://public.1rpc.io/base stalled and was interrupted. https://base.meowrpc.com confirmed the chain and closing hash but did not support eth_getLogs. https://mainnet.base.org was used only for a successful chain-ID availability check. Only the completed PublicNode scans supplied the ranking."
