X-Chain was on an undriven, unconfigured DAG engine (test-ID/height-0 vertices, a handler that dropped every inbound consensus message) — no certificate finality, no parity with C/D/P. It now runs the same linear consensuschain path as every other chain: deterministic 2/3-stake BFT certificate finality (AcceptWithCert), the BFT overlap-bound floor, and the epoch-pinned validator set. vms/xvm/vm.go: conform *VM to block.ChainVM / consensuschain.BlockBuilder (Connected/Shutdown/WaitForEvent/HealthCheck), remove GetEngine() and the dead DAG methods, add the compile-time asserts. X already had a real linear builder (embedded blockbuilder.Builder, wired in Linearize) — nothing faked. vms/xvm/health.go: HealthCheck -> chain.HealthResult. vms/xvm/tx.go: deleted (dead dag.Tx wrapper). chains/manager.go: linearize DAG-native VMs (X-Chain) into linear block mode before SetState, wired to the REAL toEngine the cert runtime reads from. Interface-gated — only VMs implementing Linearize are affected; C/D/P/Q untouched. With no production VM exposing GetEngine, the undriven DAG dispatch is dead. vms/dexvm/dexvm.go, vms/types/fee/policy.go: doc corrections (dexvm is plugin/optional/NFT-gated, linear cert finality; X-Chain UTXO fee is a deliberate exception to the account-model FlatPolicy floor). Full node builds; vms/xvm + chains tests green. Parity holds by construction for C/D/X/Q/Z: one cert path, one finality authority.
