+    **v1.4.4 — Threading and IPC safety polish (2026-05-12)**
+
+    Fifth sub-patch of the v1.4.x polish-sweep series. Threading
+    assumptions are documented per-method, a hot-path lock falls
+    away, and the privacy filter speaks up when an unknown ChatType
+    shows up.
+
+    - AutoTellTabs hot-path getter uses an Interlocked counter
+      instead of taking the lock on every read
+    - Honorific integration: per-method threading banners, plus
+      Warning-level log on unsubscribe failure
+    - AutoTranslate warmup thread marked IsBackground so plugin
+      unload doesn't wait for it
+    - PrivacyFilter logs once per unknown ChatType so a future
+      patch's added channel doesn't drop off the radar
+    - New installs persist unknown channels by default; existing
+      configs keep their explicit choice
