+# 2026-04-26 — NamespaceManager rewrite, step 36
+
+## Цель шага
+
+Убрать мёртвый код после перевода watcher-ов на `NamespaceManager` flow.
+
+## Что меняем
+
+1. Удаляем неиспользуемые helper-ы:
+   - `builderNSName()`
+   - `routerNSName()`
+   - `namespaceName()`
+2. Убираем ставшие неиспользуемыми imports.
+
+## Что НЕ меняем
+
+- не меняем runtime behavior;
+- не меняем watcher logic.
