 ### Fixed
 
 - Query diagnostics only for visible documents and count split editors once per document, avoiding a workspace-wide scan on every diagnostics event.
+- Fix double-counting of session coding time in `StatsEngine.getSnapshot()` (Fixes #22).
+- Automatically recalculate and reset inactive streaks to 0 after 2 or more days without activity (Fixes #24).
