 ## Follow-ups
 
-- User sign-in is pending in the already-opened temporary app. After login to the original account, verify live teacher-generated structures separately from fixtures. Do not request credentials in chat or bypass authentication.
+- User logged in successfully. On 2026-09-23 the user explicitly took over live validation (“具体验证我来做，你不用管”); automated native interaction stopped and the current application/login were preserved. No live validation messages were sent and no real-model component success is claimed. Deterministic tests and build evidence remain valid.
 
 ## Promotion Candidates
 
 - Promote the pinned teacher workspace, structured reply contract, explicit lifecycle/type locking and topic persistence to the canonical teacher architecture during a serialized integration task. This feature task only updates its owned task record and README.

+## User Validation Handoff
+
+- After sign-in, native AX confirmed alice and enabled teacher controls at the new worktree Renderer URL. Native AX and screenshots then disagreed, with intermittent missing-frame/window errors; bounded window reconnection did not resolve that observation problem. No further application changes or restarts were made. User elected to do specific validation themselves before any test prompt was sent.
