Under LP-0130's canonical roster, chains/thresholdvm/ hosts the M-Chain VM (MPC threshold signing). The package name "thresholdvm" was the last piece of T-Chain nomenclature still shipping in code — legacy from the pre-LP-134 shared-substrate design. Renamed to mpcvm/ so the package name matches the M-Chain letter and LP-7100 spec. - chains/thresholdvm/ → chains/mpcvm/ (dir + inner files + package decl) - Sed-replace thresholdvm → mpcvm across .go / .md / .yml / .json / .sh - Fee/settlement primitive references now say mpcvm - LLM.md canonical chain roster (LP-0130) already points at mpcvm/ F-Chain runtime pieces (fhe/, protocol/tfhe_keygen/, runtime/f_chain_adapter.go) stay under mpcvm/ for now — they consume the same shared threshold primitives. A follow-up extract to chains/fhevm/ can happen once F-Chain runtime graduates. Co-authored-by: Hanzo Dev <[email protected]>
