"""Score recent calls against the Phase 1 gate from the server log.

Usage: python scripts/score_calls.py [path/to/avc_run.log]

Reads the loguru server log, groups events per call, and reports for each call +
an aggregate: caller turns, silent non-responses, true model latency (LLM-start ->
first TTS), AVC-side termination, post-call lead written, watchdog re-prompts, and
errors. Pairs with the stereo WAVs in recordings/ for audio review.
