# The joiner stop-gap of 6 October 2026 (docs/analysis/prover-tiers-real-cards.md, the fleet night): a node that synced
# through the headers proof holds no genesis header, so the in-memory exec state never rebuilds and eth_blockNumber
# stays 0. This swaps the box's consensus datadir for a copy of the observer's full-history datadir (pulled from the
# hub over the throwaway fleet-internal key), restarts the node with the hub and the seed as peers and the proof
# verifier, and reports the follower's replay: eth_blockNumber every 15 s until it reaches the node's DAA tip.
