 ### Current Rotation Policy
 
-The logging system (implemented in `libs/hbb_common/src/lib.rs`) currently uses:
-
-```rust
-.rotate(
-    Criterion::Age(Age::Day),    // Rotate daily
-    Naming::Timestamps,
-    Cleanup::KeepLogFiles(31),   // Keep last 31 days
-)
-```
-
-**Limitation**: Individual log files have no size limit. If a single day's activity generates excessive logs, the file could grow very large and consume significant disk space.
