"""
Tests for audit_trail.py — SOUL.md honesty requirement.
Verifies:
- Every response is logged with input + sources + confidence
- Logs are stored locally (JSONL format)
- Query works: by date, session, confidence, keyword
- why() answers: why did you say X?
- Privacy: no network calls, files stay local
- Size rotation works
