Every subnet runs on one loop. Miners produce something, validators score it, and the chain turns those scores into emissions. The scores are called weights, and they are the closest thing a subnet has to a ledger of opinion. Reading them well explains most of what you see on a subnet's metagraph.
Each validator evaluates the work of the miners on its subnet using the subnet's own mechanism: a benchmark, a task, a comparison against ground truth. It normalises those scores into one weight per miner and submits them on-chain. Laid side by side, the weights of every validator form a matrix, with a row per validator and a column per miner.
