"""Thin reuse of the in-repo local-Qwen client (backend/ingest/llm.py) via Spark Control.

We import the ingest client rather than re-implementing the HTTP call so the intake bot
speaks the exact same Spark contract (model, /v1/chat/completions, TLS verify, .env load).
The intake message is real LP substance, but it goes ONLY to the local Qwen on Ten31 infra
— never Claude — so no scrub boundary applies (same basis as the daily digest). Never call a
Spark directly; everything goes through SPARK_CONTROL_URL.
