"""Full mic-free chain with the BRIDGE brain backend (not claude -p).

Runs the real wake + STT + TTS models, but builds the brain from sim-transport
configuration. Proves wake -> STT -> bridge-brain -> TTS works end to end without
a mic, without claude -p, and without a live Claude session — the exact shape of
the eventual Syl integration, minus the ssh transport.

Loads models, so run it under a memory cap, e.g.:
  systemd-run --user --scope -p MemoryMax=1500M -p MemorySwapMax=0 \
    nice -n19 ionice -c3 .venv/bin/python test_pipeline_bridge.py
