Retransmit splice_locked for 0-conf channels missing tx_signatures

This commit fixes a bug in the Lightning Dev Kit where, after a disconnection, a node could fail to retransmit a 'splice_locked' message to a peer that was still waiting for transaction signatures. Without this retransmission, the two peer…

Handle missing splice tx_signatures on reestablish

This commit fixes a bug in LDK's Lightning channel reconnection logic after a splice (a way to resize a channel's on-chain funds). If one peer had already received the splice signatures but the other had not, and then they disconnected and…

Lower strictness of pending monitor update while awaiting tx_signatures

This commit fixes a logic bug in the Lightning Dev Kit's channel splicing code. Previously, the code wrongly assumed that no unrelated monitor update could be pending when a splice `tx_signatures` message arrived while the channel was quie…

Ignore stale splice initial commitment_signed

This patch fixes a bug in the Lightning Dev Kit where a delayed message from a peer could accidentally force-close a live payment channel. During a failed 'splice' (a way to resize a channel), the peer might already have sent a signature f…

Ignore stale splice signing fuzz events

This commit changes a fuzz test (a randomized testing harness) so it no longer crashes when a simulated splice-funding signing event becomes stale. The change only affects test code, not the production Lightning library, and it ignores an …

Gate interactive commitment_signed on user approval during reestablish

This commit is purely a code-formatting cleanup. It removes a manual 'do not format' marker from one function and lets the Rustfmt tool reformat the code. No logic, behavior, or security properties of the software were changed.
