Page dashboard deltas, preserve incremental refreshes, isolate reused session IDs by creation time, and use ownership-based cache updates. Add cross-process, lifecycle, and retry coverage for the reviewed edge cases.
Hydrate bounded session output snapshots at startup and recovery, then fetch only rows newer than the monotonic SQLite cursor during steady-state dashboard refreshes.
Preserve cross-process visibility and bounded per-session caches, recover safely from transient database failures, and cover lifecycle, retry, and real child-process writes.
