Review Summary:

This PR correctly fixes an integer underflow bug in the UTXO persister service. The fix prevents underflow when calculating maxHeight = bestBlockMeta.Height - 100 during early chain bootstrapping (when height < 100).

Analysis:

✅ Correct fix: The guard condition properly handles the edge case by setting maxHeight = bestBlockMeta.Height when height < 100, avoiding unsigned integer underflow.

✅ Type safety: Both bestBlockMeta.Height and maxHeight are uint32, making the comparison and assignment type-safe.

✅ Logic preserved: For chains with ≥100 blocks, the existing 100-confirmation safety window is maintained.

✅ Comment quality: Clear inline comments explain the rationale for the fix.

No issues found. The implementation is clean and addresses the underflow bug without introducing new problems.
