Breez 0.19.0 omitted renewed-leaf ancestry; Breez 0.23 includes the missing state

What the evidence shows

Technical and product details

1. Documented behavior

   The shipped EXIT_CHAIN_STATUSES list includes Available, Splitted, and OnChain, but omits SplitLocked. 1

   34    TreeNodeStatus::Splitted,
   35    TreeNodeStatus::OnChain,
   36];

2. Protocol fact

   Spark's renewal handlers create a SplitLocked intermediate parent. 2

   398		SetStatus(st.TreeNodeStatusSplitLocked).
   399		SetOwnerIdentityPubkey(leaf.OwnerIdentityPubkey).

3. Failure

   The exit walker can stop at that parent without reporting it, leaving the printed child dependent on a transaction that is neither on chain nor in the package. 12

4. Correction

   Breez 0.23.0 includes SplitLocked in the exit-chain statuses and adds a regression test that walks through a SplitLocked parent. 3

   18/// Statuses where a node still belongs to an exit chain. `OnChain` is kept
   19/// (the SO marks a node `ON_CHAIN` once its tx confirms, still mid-exit);
   20/// `SplitLocked` is kept because a timelock renewal leaves a permanent
   21/// `SplitLocked` node above the renewed leaf that the walk must cross.

Scope control

What this does not establish

• The failure is a historical finding about 0.19.0 and wallets pinned to affected code. It should not be attributed to Breez 0.23.0. 13
