+# 2026-04-26 — NamespaceManager rewrite, step 16
+
+## Цель шага
+
+Подготовить lifecycle subscriber contract для будущего reconcile path.
+
+## Что меняем
+
+1. Расширяем `NamespaceSubscriber` методами:
+   - `OnNamespaceAdd()`
+   - `OnNamespaceRemove()`
+   - `OnNamespaceResync()`
+2. Обновляем тестовую заглушку subscriber-а.
+
+## Что НЕ меняем
+
+- не вызываем subscriber-ов из manager;
+- не подключаем contract к runtime components.
