QA: Interrupt (Headless) — LangGraph (Python)

Stub — authored for column completeness. This is a testing-kind demo (see kind: "testing" in feature-registry.json) and does not warrant a full manual checklist.

Prerequisites

• Demo is deployed and accessible
• Agent backend is healthy

Test Steps

• Navigate to /demos/interrupt-headless
• Send a scheduling prompt (e.g. "Book an intro call with sales") and verify a time-slot picker popup appears in the left app surface (not in the chat)
• Click one of the time-slot buttons and verify the popup disappears and the agent confirms the booking back in the chat

Expected Results

• Page loads without errors
• Interrupt resolves via the plain button grid (no useInterrupt render prop, no in-chat picker) and the agent continues the run with the picked slot
