+  reconnect convergence, batched refreshes, and personalized state payloads are
+  implemented; application-directed Turbo append intents are not. Batch
+  coalescing happens in the browser rather than the broadcast executor, so one

 - Backpressure: mailbox/payload/state/result caps and fair yields exist;
   distributed per-actor rate limits and global admission control do not.
 - Administration: actor and dead-letter views plus policy hooks exist; richer
   filtering, audit records, and bulk-safe tools do not.
+- Browser module coverage: the state payload and batched refresh modules have
