Because the vine stake is held until the orchard settlement, the operator carries real capital per endorsement, and the nadir audit lists each exposure.

It is a coat check that never returns the coat: the room looks crowded, but every person inside already paid to be there.","stamp":2,"sig":"2TfV2tmVPUFWo2FqcB44ubiLkDN5cVMoF6wPGjDygYMhnGypWeykv3v34hmVVJ8oRu3oNBSQgdKvo1BLg99dTUns"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:30:01.700Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
