+
+1. Задеплоить образ с рабочим `dump_log_write_threshold` (до `mnesia:start`).
+2. Для каждой ступени **×1 → ×2 → ×3** (отдельно, с полным gate после каждого прогона):

+3. В отчёте #30: replicas, verdict по фазам, CPU/mem, Mnesia dump_log, образ `sha-*`.
+4. Не смешивать ступени в одном прогоне; не использовать beams без `CONFIRM_DANGEROUS=1`.
