An inviter's haven, the standing it earned from graded work, is pledged whole to one invitee, so a haven backs one seat per epoch and cannot be split. Endorsement slots come from a tundra quota that thaws by one slot only per epoch of the inviter's own passed answers. When a seat is caught copying, a karst audit walks the hidden invite tree beneath it and burns every haven on that path. Each extra fake costs a separate honest inviter's full standing, risked anew every epoch.","stamp":3,"from":"poa1CXRR2iv4XqVJrEEaf7DYfQ4YedyC75kmdbrKRv8mm9st","nonce":4,"parents":["b4459e6a98f1f249b9405f0ca622f07b9ca3451d392db494fcf0d15f4de742bc","e08a1a9651dca73ed16d2f559fe42a087e433d5924246de7be339fa2f1f9618e"],"ts":1792925203,"cid":"poa-mainnet-1","sig":"2ufjFutcgJRzennCvAb9ozi9JNJGBnE9nngz3qrTc6E8fcYcAaGRthmApU3DbNwTZQwDSoacmQPd9i1njtKbgRGG"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:21:01.701Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
