-**Status:** ⬜ Not Started
+> **Decision (2026-05-22):** Phase 5 отложен как post-merge follow-up. Phases 1-4 уже дали lab.html 5180→3499L (-32%) и решили основные задачи (modular CSS, modular glue JS, token purification, deep-link routing). Phase 5 требует рефакторинга 38 engine классов (нужен `destroy()` для cleanup), memory-leak verification, и риск сломать любую из 38 симуляций. Лучше merge'нуть 4 чистых фазы и оценить в проде.
