What
The interactive session no longer holds its message list in a React reference; a per-session store holds it and roughly 50 call sites read a snapshot from it. Every write also records the message count and an estimated token count into transcript state, keeping the tool-use and token counters in step with the messages.
Evidence
progress: { toolUseCount: 0, ...i.progress, tokenCount: n }
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
