A plugin is its own binary; the daemon that loads it has no business being linked into it. Twelve VMs reached into github.com/luxfi/node for four things, and each one now programs against a home that is actually its own: - fee admission (Policy, FlatPolicy, NoUserTxPolicy, Validate) joins the settlement half already in chains/fee. One fee package, and the nodefee alias that marked the split is gone. - the cross-chain artifact types move to chains/artifacts. - the factory the daemon registers is luxfi/vm/manager.Factory, and the version types are luxfi/version. Both are ordinary modules the daemon reads too, so a VM imports them directly rather than through anything of ours. The GPU switch is deleted, not moved. It was a global set during daemon startup that a separate process could never observe, so every plugin read its default; FHEOptions.Backend is the switch that was really there. go list -deps names no luxfi/node for aivm, bridgevm, dexvm, evm, fhevm, graphvm, identityvm, keyvm, mpcvm, quantumvm, schain or zkvm, and the built plugin binaries carry no such string. oraclevm and relayvm still do: they are re-export shims over luxfi/oracle and luxfi/relay, which build their fee policies upstream. Their tests keep naming the daemon's fee package because that is the type their value has.
