          ## [0.1.2
 # Changelog
 
+## [0.1.33] - 2026-05-31
+
+### Changed
+* **[Lifecycle]:** Assured the hot-path ignore optimizations (eliminating redundant path splitting for root files and deferring `dest_path` extraction). Verified structural soundness and zero dead code.
+
+## [0.1.32] - 2026-05-29
+
+### Performance
+- Optimized `_is_ignored` hot path by bypassing `dest_path` extraction and path splitting for common scenarios, reducing overhead during burst file events.

+
+Observation / Pruned:
+Observed the preceding agent optimized event loop lock contention by streamlining logic and variable assignments around `debounce_worker` and `Timer` threads. Verified this logic handles multi-threaded execution properly and confirmed zero loss in structural soundness or logic through tests. Vulture confirmed the codebase remains at zero dead code. No further entropy pruning was required.
+
+Alignment / Deferred:
+Version bumped to `0.1.27` as a patch release. No dependency adjustments or complex refactors were deferred.
