+# 2026-04-26 — NamespaceManager rewrite, step 41
+
+## Цель шага
+
+Довести explicit removal strategy до полного покрытия watcher lifecycle paths.
+
+## Что меняем
+
+1. `HandleWatcherNamespaceUpdate()` теперь тоже принимает `NamespaceRemovalStrategy`.
+2. `managed -> unmanaged` path использует ту же policy, что и `DeleteFunc`.
+3. Добавляем unit test на update-path с `dispatch-remove`.
+
+## Что НЕ меняем
+
+- текущие watcher-ы остаются на `track-only`;
+- runtime cleanup policy по умолчанию не меняется.
