"""
Tests for #24870 — Telegram: audio file attachments must NOT be routed to STT.

Telegram distinguishes three kinds of audio payloads:
  - message.voice  → Opus/OGG voice message  → STT pipeline
  - message.audio  → audio file attachment   → file path note, NOT STT
  - message.document (audio mime) → generic file route

These tests confirm that:
  1. MessageType.VOICE events still flow through the STT pipeline.
  2. MessageType.AUDIO events bypass STT and get a file-path context note instead.
  3. Mixed media lists (voice + audio) split correctly.
