Also update it to more closely match the persisted version which has the v1 and v2 only fields as optional. Refactor ChannelAuthProof to support both v1 and v2 channel announcements: - Add Version field to distinguish v1 from v2 proofs - Wrap v1-specific fields (NodeSig1/2, BitcoinSig1/2) in fn.Option since v2 doesn't use them - Add optional Signature field for v2's single schnorr signature - Add constructor functions NewV1ChannelAuthProof and NewV2ChannelAuthProof to enforce correct initialization - Add getter methods (NodeSig1(), BitcoinSig1(), etc.) that safely unwrap options, returning empty slices when not present The IsEmpty() check is updated to handle both versions correctly. Both stores validate v1-only for now.
routing
The routing package implements authentication+validation of channel announcements, pruning of the channel graph, path finding within the network, sending outgoing payments into the network and synchronizing new peers to our channel graph state.
