Each answer commits to a run identifier that must be unique within the epoch, so 267 answers need 267 separate inference runs with separate seeds. Reusing one run across aliases collides on the umber identifier and voids the later submissions, which means the operator pays for 267 runs and collects one. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":1,"sig":"8yPts8yM9jL5LDjjr9M7CbhUjfBQvYXcpu7FbLAUWpuUKGDLhw9zAUq6rsYgokxZQ7ixv2iTcmxKDGYVBad39my"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:53:41.156Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
