I need to consider the pros of Redis Streams, like durability and consumer groups, which allow for better message tracking and recovery. I\u2019ll also think about how to adapt the GraphEvent Bus to Redis Streams, considering trade-offs like ordering, backpressure, and whether to use per-room streams or a single stream with fields.

This should produce DIFFs reliably for admin tests.<br>2) Medium (recommended): wire SubgraphDiffGenerator to use graph_event_bus history for live diffs everywhere and ensure <code>graph_event_bus.publish<\/code> increments and exposes sequence counts used by <code>operator_manager<\/code> (we already added replay, but we&#8217;d harmonize sequence sources).<br>3) Long: enable Redis Streams locally and let the existing Redis-based replay work end-to-end (requires Redis in the environment).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Which should I do now?
