Answer this question about chain 8453 over blocks 52171148 to 52172947 (closing hash 0x470bf60226eecb1b731c8fec40c6d2d98a267a0d94751ae424d8a8730a50a87c), exactly as .imd/reads/oracle.json pins it: On Base, what was the Uniswap v4 spot price of pool 0xf75abf8b552feb6cc784c1432b731276f253dff4b72ec0b2162444efca39a4a9 (USDC/CAS, currency0/currency1) the median over 5 evenly spaced blocks of the window (blocks 52171148 to 52172947, about 2 hours before 52176547), as currency1 per 1e18 raw currency0 in raw units? Answer type: uint256. Evidence: chain. Definitions the requester fixed: - recipe: {"kind":"univ4-spot","poolManager":"0x498581ff718922c3f8e6a244956af099b2652b2b","poolId":"0xf75abf8b552feb6cc784c1432b731276f253dff4b72ec0b2162444efca39a4a9","invert":true,"samples":5} — write recipe exactly this; compute with scan.mjs --v4-spot --invert --samples 5. - pool: PoolManager 0x498581ff718922c3f8e6a244956af099b2652b2b; currency0 is USDC 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913, currency1 is CAS 0xf1070fd43cd11af8da18ff4edfb1a18279cd6f67. Public endpoints for chain 8453, verified; use one: - https://base-public.nodies.app - https://base-mainnet.public.blastapi.io - https://public.1rpc.io/base - https://base.meowrpc.com - https://base-rpc.publicnode.com - https://mainnet.base.org Three steps: (1) compute it with node .imd/reads/skills/oracle-assess/scripts/scan.mjs over exactly those blocks, from one of the endpoints above; (2) write artifacts/answer.json with the recipe that reproduces it; (3) run node .imd/reads/skills/oracle-assess/scripts/check-answer.mjs and fix what it prints. Scan again only when the total is zero or the checker objects. Nothing else needs reading first: the brief above is in .imd/reads/oracle.json with the recipe parameters, and .imd/reads/skills/oracle-assess/REFERENCE.md explains a field if the checker asks for one.
