- vms/thresholdvm/ → vms/mpcvm/ (dir + inner files + package decl).
- node/vms.go optional-VM registry: drop ThresholdVMID row, add
MPCVMID and FHEVMID rows (matching the new split).
- genesis/builder/registry.go: T-Chain entry → M-Chain (MPCVMID) +
F-Chain (FHEVMID); registry_test.go parity assertions updated.
- genesis/builder/builder.go: TChainAliases → MChainAliases +
FChainAliases; ThresholdVMID switch case split to MPCVMID / FHEVMID;
optIn chain slice uses config.MChainGenesis + config.FChainGenesis
(T-Chain slot retired).
- LLM.md: point at LP-0130 as canonical topology + fee spec; correct
the quantumvm posture to service-only per LP-0130 §6 (Q-Chain has
no user-payable blockspace).
Build + vet clean on chains/mpcvm/... + node/{vms/mpcvm,genesis,node}/...
