docs/ and DESIGN.md described protocol/{cggmp21,frost,corona_general,
tfhe_keygen} — four interface-only packages with no implementation and no
importer, deleted this pass — and pointed at a chains/mchain/ tree that does
not exist, which LLM.md already says never did. Prose describing an unbuilt
system reads as a contract; the reader who believes it looks for code that
isn't there.
What is true moves into LLM.md: the constants that must stay constants because
Verify enforces them, the two checks that must read consensus state rather than
the document being checked, and the boot fault that made a share-holding
validator unable to restart.
The lane that did this was killed before it could commit; the tree it left is
green and is preserved here rather than lost. Root package 51.5% at the start
of the day, 93.3% at its last checkpoint, 98.6% now, with cert, fhe, types and
cmd/plugin all passing.
Includes the fault-injection suite it was building when it stopped: a node that
cannot read its state does not start, and one that cannot enumerate its
registry does not either.
Not reviewed by me beyond build, vet, gofmt and the full suite under -count=1.
The lane's own report is owed and did not arrive, so its mutation count and its
verdict on the mpcvm/fhe duplication are unrecorded.
Flip the Q-Chain fee gate from FlatPolicy (user-fee metering) to the
committee-only fee.NoUserTxPolicy sentinel. Finality-cert inclusion is
a validator obligation paid via P-Chain reward distribution; a fee
market on Q would make finality hostage to blockspace pricing — the
exact failure mode LP-0130 §6 eliminates. Consensus-internal cert
aggregation reaches txPool.AddTransaction directly and is unaffected.
Tests updated: policy is the NoUserTxPolicy sentinel and IssueTx
refuses every user tx (zero-fee, floor-fee, and 1000x floor) with
ErrChainAcceptsNoUserTxs. go test ./quantumvm/ passes; build + vet
clean.
Closes the top divergence from the 2026-07-03 LP-vs-code audit.

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.
