Adds the re-exports luxfi/consensus needs through the canonical
threshold/protocols alias surface so the consensus engine no longer
imports luxfi/corona/* or luxfi/pulsar/ref/go directly.
Protocols/corona top-level gains Params, NewParams, GenerateKeys,
VerifyBatch, VerifyBatchAll forwards on top of the existing
Signer/KeyShare/GroupKey/Round1Data/Round2Data/Signature/Verify/
NewSigner type aliases.
New subpackages mirror the luxfi/corona namespace:
protocols/corona/keyera -> luxfi/corona/keyera
protocols/corona/primitives -> luxfi/corona/primitives
protocols/corona/reshare -> luxfi/corona/reshare
protocols/corona/sign -> luxfi/corona/sign
protocols/corona/gpu -> luxfi/corona/gpu
A new protocols/pulsar subpackage mirrors luxfi/pulsar/ref/go/pkg/pulsar
covering Mode constants, Params/ParamsP{44,65,87}/ParamsFor, the
key/share/signature types, identity layer (IdentityKey,
IdentityDirectory, SymmetricSession, GenerateIdentity), two-round
threshold signing (ThresholdSigner, NewThresholdSigner, Combine),
DKG (DKGSession, NewDKGSession, DKGOutput, DKGRound1Msg, DKGRound2Msg),
and the single-party FIPS 204 baseline (GenerateKey, Sign, VerifyCtx).
The re-exports are type aliases and thin function forwards; no
behaviour change. The underlying corona kernel and pulsar reference
implementation are unchanged.
go.mod bumps luxfi/corona v0.4.1 -> v0.7.5 (needed for the gpu
subpackage, which appeared at v0.7.2) and adds luxfi/pulsar v1.0.12
matching the consensus consumer. Pre-existing prometheus-stack indirect
deps stripped by go mod tidy because the metric sweep already removed
the direct consumer.
Closes the 22-file layering violation flagged by the 2026-05-31
integration audit. The consensus consumer that target these new
alias paths lands in a companion commit on luxfi/consensus.
Layering shape after:
consensus -> threshold/protocols/{corona,pulsar} (stable alias)
