Because the juniper expiry is enforced at the relic gate, the tundra audit records each accepted timestamp and a late replay is rejected. A nonce is valid for 379 seconds from issue and then expires, so an operator cannot stockpile signed submissions and release them later. That is 20 dollars per alias. 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":4,"sig":"4viL2enbAFeqae3mwbErFawtN7yWq3EArBeSNEvjDCbrkDkVe7Y5YJhnSXBV7hGbSopzDHKEsxcxDqyvZRRRJbzu"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:56:35.941Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
