# The shipper's exec recovery (6 October 2026, 16:20Z): a box whose exec layer sits at tip 0 "from snapshot" (the genesis
# replay after the 15:43Z reorg wrote a tip-0 exec-snapshot.bin, which loads first and is served to peers) takes node 1's
# exported snapshot (tip chain block 130,272, sha256 ac101f13...): stop the node, delete the data dir's exec-snapshot.bin
# and .prev.bin, start the node as before plus --igneum-exec-snapshot=<file>,0x<sha256>; then eth_blockNumber climbs
# from 130,272 to the sink within a minute. SNAP = the file's path on this box.
