One toolchain across the estate. The tree carried 1.26.0, .1, .3, .4 and .5
at once, so which compiler built a binary depended on which repo it came
from.

The previous commit carried go.mod changes from modules that do not build,
which is not a state worth publishing. Restore those and keep the pins for
the modules that resolve and build clean.
The bulk retag moved published tags. go.sum and sum.golang.org hold the
original bytes, proxy.golang.org answers not-found, and the direct fetch
disagrees, so builds stopped at a checksum before reaching a compiler.
Pin forward to versions the proxy still serves.
Solana addresses were correct and receive-only: ConsensusKeyInfoStore.Save was
the only RegisterKey caller and hardcoded "secp256k1", and TriggerSign read the
curve from that field, so no product entry point could reach Ed25519 signing.
The hardcode is not fixed, it is UNREPRESENTABLE. transport.KeyInfo.KeyType is
deleted — the record carries one public key per curve and a PublicKeyFor(curve)
— and RegisterKey lost its keyType parameter, so there is no longer a place to
state a curve wrongly. A scalar KeyType was the wrong shape anyway: one keygen
ceremony produces BOTH a secp256k1 and an Ed25519 key, so "what curve is this
wallet" has no single answer.
The request carries the network instead, and ONE table maps it to a curve, with
NO default arm — KeyTypeForNetwork returns ErrUnknownNetwork rather than
guessing. That is the point: the old default returned secp256k1 for anything
unrecognized, which is how a Solana request would have been signed with the
wrong key.
/sign's 32-byte clamp becomes the SCHEME's rule rather than the endpoint's:
secp256k1 signs a digest and requires exactly 32 bytes, Ed25519 signs the
message at any length. /sign no longer accepts key_type at all — two ways to say
the curve is the misuse being removed — and Network is bound into the
idempotency fingerprint, so the same bytes for SOL and ETH conflict instead of
sharing one cached signature from a different key.
⚠ The trap this nearly shipped with: every pre-existing KeyInfo record has EMPTY
public keys, because the old Save wrote "", "". A naive "does this wallet have
this curve" gate would have refused every existing wallet on every curve. The
check is gated on RecordsCurves() — a record naming no curve denies none, and
the missing share stays the thing that fails closed.
Verified end to end, not by mirroring: a Solana request through
ConsensusMPCBackend.TriggerSign with a real 2-of-3 FROST ring produces a
signature crypto/ed25519.Verify accepts, over a 63-byte message so any
reintroduced clamp or pre-hash fails it; ETH/EVM/BTC/LUX still route to
secp256k1 and must RECOVER to the wallet's key. Four mutations tried, all
caught.
Behavioral risk worth naming: an unrecognized chain string now fails its
transaction closed rather than signing with a default. That is correct, and the
real fix is validating chain at POST /v1/transactions.
The luxfi/{age,mpc,pq} tags were force-updated upstream, leaving the
recorded go.sum hashes pointing at pre-retag content. Refresh the
checksums at the SAME pinned versions (no version bumps) so the root
module and the e2e module build. All are GOPRIVATE-covered first-party
modules, so no sumdb authority is bypassed.
Unblocks: e2e/live_http_sign_test.go builds mpcd for the live 3-node
consensus ceremony.

luxfi/* and hanzoai/* are PUBLIC Go modules. The GOPRIVATE / GONOSUMDB /
GOPROXY=direct env in Dockerfile + release.yml routed fetches around
proxy.golang.org + sum.golang.org, "working" only by skipping checksum
verification — which poisons go.sum with force-republished git bytes that no
longer match the immutable checksum db. Drop the bypass; resolve every
luxfi/hanzoai checksum from the public proxy + sumdb instead.
Poisoned deps resolved (strip luxfi/hanzoai go.sum lines, then go mod tidy):
- github.com/luxfi/edwards25519 v0.1.0 -> v0.1.1 (the agl/ed25519 replace
target, in both go.mod and e2e/go.mod): v0.1.0 was force-republished, its zip
hash diverges from the sum.golang.org pin and no copy verifies; v0.1.1 is the
clean patch the proxy + sumdb agree on.
- github.com/luxfi/age v1.4.0, github.com/luxfi/zap v0.8.1: version healthy, but
go.sum carried poisoned zip hashes — corrected to the sumdb canonical values.
- e2e/go.sum: also completed to the full canonical checksum set (hack-era builds
with GOPROXY=direct skip go.sum completion).
Verified with GOWORK=off (matching the .dockerignore'd workspace + CI):
- go mod verify -> all modules verified (main + e2e)
- CGO_ENABLED=0 go build ./... clean (main + e2e)
- go test ./... -> 35 ok / 0 FAIL; signing, threshold, keygen, attestation, kms,
ristretto255 curve, sr25519, and policy-gated sign-flow tests all pass. No
crypto regression from the edwards25519 curve-lib bump.
Dep-checksum tail left uncommitted after 5c4d5cb removed bls_keygen_session.go.
- main go.sum: luxfi/zap v0.8.1 + luxfi/age v1.4.0 h1 refresh (upstream same-version
tag re-cut; go mod verify = all modules verified, build green).
- e2e/go.mod + e2e/go.sum: go mod tidy churn (nats.go v1.50.0 -> v1.52.0 within v1,
added indirects) for the e2e test module.
- go.work.sum: workspace checksum sync.
GOWORK=off go build ./... exit 0; go mod verify clean.
Consensus mode learned only its OWN Ed25519 public key: peer keys arrive in
ReadySignal.PublicKey during the transport identity handshake (sendIdentity) but
were discarded — never fed to the ConsensusIdentityStore that VerifyWireMessage
consults. Result: every inbound CGGMP21/FROST/signing wire message from a peer
was dropped ("public key not found for node …") and keygen/signing stalled to a
60s timeout. The HTTP /keygen and /sign endpoints could not work in any real
multi-node ensemble.
Fix (orthogonal, no import cycle): transport.Config.OnPeerIdentity observer is
invoked (notifyPeerIdentity, with self/empty/length guards + defensive copy)
whenever a peer key is learned — from the MsgMPCReady handshake in handleMessage
and handleIncoming. The acceptor now also replies with its own identity so the
key exchange is symmetric on the single tie-broken connection. main.go wires the
observer to ConsensusIdentityStore.AddPeerPublicKey. This is the consensus-mode
analog of the legacy NATS path's peers.json + *_identity.json seeding.
Proof: e2e/live_http_sign_test.go (//go:build integration) builds mpcd from the
repo root, starts a real 3-node 2-of-3 consensus ensemble, and over the live
HTTP API proves: distributed CGGMP21 keygen (real evm address), a real threshold
signature, idempotency cached-match, anti-oracle 409 on key reuse with new
content, 400 on empty key, and no plaintext key in any response or node log.
Unit coverage for the observer guards in pkg/transport/peer_identity_test.go.
Also fixes a pre-existing standalone_test.go bug: it set only ZAPDB_PASSWORD but
the env HSM provider reads MPC_PASSWORD — set both so the node starts.
Bump e2e submodule's luxfi/threshold pin (v1.5.5 → v1.9.9) to drop the only
remaining corona puller in this workspace. Removes the residual
'github.com/luxfi/corona v0.2.0/go.mod' hash line from go.work.sum.
Align go.work go directive to 1.26.4 to match both workspace siblings
(../threshold and ./e2e). No source code in this repo imported corona;
this was workspace-graph hygiene only. R-LWE threshold primitive is now
referenced exclusively via luxfi/corona upstream.
Adds the topology contract that lets a fund run mpcd as its own private
cluster — no Lux primary network registration, no shared M-Chain audit
ledger — using the same code path and the same operator surface.

pkg/audit:
- Append-only Merkle hash chain. Tampering with any historical event
invalidates every subsequent hash. Canonical bytes use fixed-order
concatenation (json.Marshal map ordering is non-deterministic).
- WORMDispatcher: NDJSON append, replay-on-start, fsync per Append.
- MChainDispatcher: batched POST of (batchHash, fromSeq, toSeq) to a
configurable anchor RPC.
- compositeDispatcher: fan-out to multiple legs with per-leg sealing.
- S3 Glacier Vault / Azure Immutable / GCS Object Lock dispatchers
fail closed — wired into the flag surface but gated behind the
cloud-audit build tag, no silent fallback.
pkg/identity/bootstrap.go: identity creation + (primary-mode only)
registrar announcement. Same on-disk format as the previous
loadOrGenerateIdentity (which is now removed); private mode is silent.
deployments/k8s-private: fund-only Kustomize overlay. Standalone
namespace, NetworkPolicy that blocks egress to anything outside the
fund's VPC, hardware-WORM PVC for the audit log, KMS-driven secret
template.
deployments/k8s-primary: env-var patch overlay on the existing lux-mpc
base. composite(local-worm,mchain) by default.
deployments/terraform/{aws,gcp,azure}: VPC + audit storage modules.
terraform validate passes; EKS/GKE/AKS + HSM modules are stubbed and

CheckKeyInAllNodes was assigning *badger.DB to kvstore.Store.DB which
requires database.Database — badger.DB is missing the Compact method.
The test only needs Get and Close, so use badger.View/txn.Get directly.
- Run goimports -w on all 17 Go files with formatting issues
- Set CGO_ENABLED=0 on all CI steps (test, lint, build, CodeQL, SBOM)
- Remove -race flag from tests (requires CGO which pulls in blst.h)
- All 17 test packages pass with CGO_ENABLED=0
e2e now references github.com/luxfi/mpc v1.0.5 (semantic tag).
