This is a large sync against upstream lnd, bringing BOLT 12 offers, onion messaging, production Taproot channels, and RBF-based cooperative close, alongside the walletd/neutrino Start(ctx) API migration and several fixes from this cycle's review.

Highlights​

BOLT 12 (new)​

  • Offer and InvoiceRequest message structs with TLV codecs and full BOLT 12 reader/writer validation.
  • NewInvoiceRequestFromOffer for building a request from an existing offer.

Onion Messages (new)​

  • Actor-based onion message forwarding with a token-bucket rate limiter and an LRU-cached SCID resolver.
  • BFS pathfinding for onion messages, blinded-path support, and a --protocol.no-onion-messages flag.

Taproot Channels (production)​

  • Production Taproot channel negotiation, gated behind explicit negotiation and rejected for public channel opens.
  • Commitment generation, HTLC resolvers, and the nursery all integrate production Taproot support.

RBF Cooperative Close​

  • A dedicated RBF close actor decouples RPC-driven fee bumps from the peer actor.
  • Cooperative close now insta-dispatches CLOSED_CHANNEL on first confirmation instead of waiting.

Channel State Refactor​

  • Channel state, commitment, forwarding-package, and revocation-log storage moved behind a new chanstate.Store interface.
  • Closed channels on KV-SQL backends are now tombstoned instead of bulk-deleted.

RPC​

  • DeleteForwardingHistory and SubmitPackage (v3 CPFP package relay) RPCs and CLI commands.
  • Removed the deprecated SendPayment, SendToRoute, and TrackPayment RPCs (routerrpc V2 equivalents remain).

Fixes​

  • chain.Interface.Start now takes a context.Context, matching the same change in walletd/flokicoin-neutrino.
  • Fixed a panic in the DNS fallback SRV lookup; RPC handler panics are now recovered.
  • BOLT-02 push_msat bound is now enforced on the fundee.

Dependency Security​

  • Bumped golang.org/x/crypto to v0.52.0 and google.golang.org/grpc to v1.79.3, closing GHSA-p77j-4mvh-x3m3 (a gRPC authorization-bypass advisory) among others.
