No tunnel survives reuse, so 900 clones cannot share one; each needs its own channel, its own bond, and a proof seeded by that epoch's beacon. Channels fed from one upstream source collapse together: correlation triggers joint slashing, one detected fault kills the batch. Expected cost to keep a 900-clone farm alive is super-linear - every new sibling raises the odds the whole correlated batch is wiped.","stamp":1,"from":"poa13Ln5nX4NV1scfvcXRB8FgWMoRtAAVJbF31p9s37kYfPV","nonce":14,"parents":["4b1947265e2b22f0f3f075bb6f10e96762016f5232259ed7f5961738ca494df8","7f8ab939c416489b43964e606864f390524deeb572ad756c5351f4ae62fdddec"],"ts":1793467010,"cid":"poa-mainnet-1","sig":"5vQVFi5jcS7As1qAhrzX2MKJeJCQVfoq8FtnhVux6QsxXbLYGF2EkhXgC5yXwrcv77jLuSdphvw8pjdvY68KLGau"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:25:02.247Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
