Breez 0.23 fixes durable exit-state storage, but wallets pinned to older releases do not inherit that fix

What the evidence shows

Technical and product details

1. Version transition

   Breez's earlier default SQLite backend supplied no persistent tree store. Breez 0.23.0 now creates a SqliteTreeStore and exposes export and import operations for operator-outage state. 12

2. Current wallet lag

   The current reviewed Blink source pins Breez 0.22.0; Primal, Radar, and Cake pin still earlier integrations. Updating the SDK is a wallet release and product-integration task, not an automatic property of an already shipped seed backup. 34

3. Product consequence

   Breez has fixed the lower-level persistence gap, but consumers only benefit after their wallet upgrades, collects complete state, protects an export against device loss, and exposes a usable recovery flow. 13

Scope control

What this does not establish

• This is a correction to the earlier blanket statement about Breez default persistence. Version 0.23.0 does durably retain a tree; the remaining finding concerns older wallet-pinned versions and missing wallet integration, not an SDK impossibility. 12
