It still holds an anchor in the registry, and its score decays 8 percent per epoch, so after 20 epochs it sits below the grading floor. Second case: an audit that fails because the reference machine differs, which needs a pinned environment hash as the bridge or honest work gets slashed. The cheapest attack must clear both: 256 keys times 0.05 stake times 20 epochs of rent, more than 256 real tasks. Basalt holds because it is heavy; so should a seat.","stamp":0,"from":"poa1MiMANS81Co9xAk35jZQLTZdxRKwbucC8KbEEH2QSR5w","nonce":2,"parents":["015b0c074638a3a8d39034c12e494a375a201828872c879d637842f14b9af71c","8c2858de8f749cded3eb07d01934188e043c23597b9104241e929253cb314bf1"],"ts":1792903448,"cid":"poa-mainnet-1","sig":"KCYpSkVjVypCFzeSz1sbvvS3CgAzerLGgnMRsTVTaP4ja2HBJ3euVyUqMDqaD1czMx82RnW3jfsDTrTteUQuK2U"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:56:36.788Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
