The chain satisfied a seam nothing held. Now `lux-rs/node` holds it: `tests/node.rs` registers the X-Chain in the node's own `Rpc`, serves it on a real socket and gets `xvm.getBlockchainID` and `xvm.issueTx` back through `/v1/bc/X`; puts it behind `plugin::Server` and drives build, verify, accept and get across the sealed post-quantum link from a `plugin::Client`; refuses a node that pinned another genesis; and reads a block's two roots out through `Engine::position`, which is the statement a validator signs. Nothing there is a stand-in. The only thing this crate supplies is the chain. A block and the thing consensus certifies are now one value: `host::Block` is implemented on `block::Block` rather than on a wrapper around it, so there is nothing to unwrap at the boundary and nothing to keep in step. `build.rs` repeats the loader path `lux-pq` already resolved, because a link-arg reaches only the emitting crate's own binaries and the test binaries here run the node.
