"""Interactions API basics (REST): create → stream (SSE) → chain with previous_interaction_id → GET → DELETE; store=false variant.
STATUS: LIVE_VERIFIED 2026-09-18 (gemini-3.5-flash-lite, tmp-live/gemini-tools/h1..h9*.json, < $0.001).
Observed: response keys {id, object:"interaction", status:"completed", model, created, updated, service_tier, steps[], usage};
steps = [{type:"thought", signature}, {type:"model_output", content:[{type:"text", text}]}]; SSE events in order:
interaction.created, interaction.status_update, step.start, step.delta, step.stop (per step), interaction.completed;
store=false → no `id` in the response; GET after DELETE → 404 "Requested entity was not found"; GET /v1beta/interactions (list) → 404.
Run: .venv/bin/python examples/gemini/interactions/interactions_basic.py
