DanS	b780587d26	Fix change detection: handle empty memo correctly ... memo.to_utf8() returns Some(Ok("")) for change outputs with all-zero bytes, not None. The previous check (memo.to_utf8().is_none()) never filtered change outputs because 0x00 < 0xF5 makes to_utf8() treat it as valid text. Now properly checks for empty string as well.	2026-03-22 10:30:04 -05:00
DanS	ae059a7238	Fix change output detection using IVK instead of static address list ... - Use try_sapling_note_decryption with IVKs to detect wallet-owned outputs - Correctly identifies change sent to diversified addresses - Prevents change outputs from appearing as external recipients in tx history	2026-03-22 09:14:08 -05:00
DanS	43966f6aae	Add clean shutdown, atomic wallet save, and backup recovery ... - Add shutdown_flag (AtomicBool) to LightClient for clean thread termination - Mempool monitor threads check shutdown flag and exit gracefully - Add pub fn shutdown() method to set the flag - Atomic wallet save: write to .dat.tmp then rename, preventing corruption on crash - Create .dat.bak backup before each save - Auto-recovery on startup: if wallet file missing/corrupted, restore from .bak	2026-03-21 05:38:57 -05:00
DanS	a6a80dc224	Crash fixes, reorg handling, and sync performance improvements ... - Fix FFI panics with catch_unwind and safe CString construction - Handle poisoned mutex/RwLock after prior panics instead of crashing - Fix empty block list panics in clear_blocks and invalidate_block - Reuse Tokio runtime across block fetch batches to reduce overhead - Add fetch_blocks_with_runtime for caller-managed runtime lifecycle - Update branding, dependencies, and checkpoints for DragonX	2026-03-21 03:55:18 -05:00
