Because the grove stake is held until the copper settlement, the operator carries real capital per endorsement, and the mirror 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":1,"sig":"4YMjyQeg6HPU1Lf6WW8vbWmDocjhWcSY6SbhD5MywqyGfsY82qr78bGjdWJbjRJ4njdp4WBNitV7uMCQt4gPoAVx"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T15:12:01.847Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
