Chat Fixture - Horizontal Shift Validation

Chat Horizontal Shift Fixture

This page simulates the chat message flow to validate that NO horizontal movement occurs when streaming completes.

Validation Steps:

  1. Click "Start Simulation" to begin the message flow
  2. Watch carefully as the assistant response streams
  3. At the moment streaming completes, observe if ANY horizontal movement occurs
  4. Expected: ZERO horizontal shift (both messages stay perfectly stable)

Current Phase: empty
