The startup --import-chain-data path (vm.go, after importBlocksFromFile) advanced
core.BlockChain + acceptedBlockDB to the imported tip but never refreshed the
in-memory consensus wrapper vm.State (components/chain), which initChainState had
built at the pre-import genesis tip. On the FIRST import boot the consensus engine
then reads genesis while the EVM head is the imported tip and the proposervm wedges
("BuildBlock: preferred block not fetchable", preferred=empty id) until a restart
re-runs initChainState off acceptedBlockDB.
admin_importChain runs on a LIVE node whose vm.State is already current, so only the
startup path needs this. Now syncs vm.State via the existing, boot-safe
chain.State.SetLastAcceptedBlock, fail-closed (a boot that cannot establish the
imported tip stops loudly rather than serving consensus at a stale genesis).
Empirically proven on lux-testnet 96368 / node v1.36.17 (luxfi/evm v1.104.9): first
import boot wedged at tip 251, healed only on restart; with this the first boot
finalizes past the import tip with no restart. Imported-state execution / stateRoot
unchanged.
