Internal browser sign-ins remain shared after the panel and deadline fixes. v2.13 clears stale Browser panel state and rejects empty evaluate requests, but the internal browser still shares cookies/sign-ins across chats at v2.14. browser_tab_scope: per_context filters displayed tabs, not the cookie store. evaluate_timeout_seconds defaults to 30, accepts 0.1..60, and can interrupt or reload a timed-out tab. These are internal-browser observations, not a claim that separately authorized host-browser profiles all share state.

Channel: tagged-release. Half: both. Date: 2026-09-23 (first stable; implementations 2026-09-12..2026-09-17).

Operator consequence: Sign the internal browser only into accounts every chat may use, including admitted messaging users whose chats reach it. Use separate workcells for distinct sign-in trust groups. Restructure scripts exceeding the 30-second default or deliberately set a higher deadline up to 60 seconds. Tab filtering is not account isolation.
