Add CombinedNonce() and RegisterCombinedNonce() methods with full implementation stack. Interface and core implementation: - input/musig2.go: Added methods to MuSig2Session and MuSig2Signer interfaces - input/musig2_session_manager.go: MusigSessionManager implementation using HaveAllNonces flag for state tracking (simplified, no extra fields) - internal/musig2v040: Stub implementations returning ErrUnsupportedMethod - Mock implementations (MockInputSigner, MockSigner, DummySigner) RPC layer: - lnrpc/signrpc/signer.proto: RPC method definitions and messages - lnrpc/signrpc/signer.yaml: REST API endpoint mappings - Generated protobuf code (all .pb.go files) - lnwallet/rpcwallet/rpcwallet.go: RPCKeyRing client implementation The proto types and RPCKeyRing are added together since RPCKeyRing implements the Signer interface and requires proto types to fulfill the contract. For v0.4.0, these methods return ErrUnsupportedMethod. Use MuSig2Version100RC2 to access these features.
MuSig2 v0.4.0
This package contains an exact copy of the MuSig2 code as found in
github.com/btcsuite/btcec/v2/schnorr/musig2 at the tag btcec/v2.2.2.
This corresponds to the MuSig2 BIP specification version of
v0.4.0.
We only keep this code here to allow implementing a backward compatible, versioned MuSig2 RPC.
Unsupported Methods
The following methods from the newer MuSig2 specifications are not supported in
this legacy v0.4.0 implementation and will return ErrUnsupportedMethod if
called:
CombinedNonce(): Returns error instead of the combined nonce.RegisterCombinedNonce(): Returns error instead of registering a pre-aggregated combined nonce.
These methods are only available when using MuSig2 v1.0.0rc2 or later. To use
these features, create sessions with MuSig2Version100RC2 instead of
MuSig2Version040.
