 ## [Unreleased]
 
+## [0.4.1] - 2026-08-20
+
+Release validation no longer races an FSEvents stream rearm when a watched
+session-store root appears for the first time.
+
+### Fixed
+- **Late-root FSEvents integration coverage is deterministic.** The test now
+  waits until the watcher has narrowed from the nearest existing ancestor to
+  the newly created root before writing its probe file, matching the
+  production restart/rescan contract and removing the stream teardown/startup
+  gap from the assertion.
