 - **Microtask event batching** — rapid child session events are coalesced into a single parent invalidate per microtask boundary, preventing UI jank during bursty tool execution.
 - **Epoch-based invalidation** — the spawn renderer uses epoch counters rather than pointer comparison to detect stale sessions, making ownership checks reliable across session resets.
