+デフォルトで有効になっており、既存の動作と互換性があります。無効にすると毎晩の自動蒸留が実行されなくなります。MEMORY.md を手動管理したい場合や LLM 呼び出しを 1 回節約したい場合に適しています（日次記憶の要約には影響しません）。手動コマンド `/memory dream` もこのスイッチの影響を受けず、いつでもトリガー可能です。

+## Config Toggle

+Control the nightly automatic distillation via `deep_dream_enabled` in `config.json`:

+
+Enabled by default to keep existing behavior. When disabled, the nightly distillation no longer runs — useful if you prefer to maintain MEMORY.md manually or want to save an LLM call (daily memory summarization is not affected). The manual `/memory dream` command is also unaffected and can still be triggered anytime.
