# VERIFICATION_STAMP
# Story: AIVA-019
# Component: test_aiva_briefings.py
# Verified By: Claude Sonnet 4.5
# Verified At: 2026-01-26T00:00:00Z
# Test Coverage:
#   - Black-box: Briefing generation (complete data, storage)
#   - Black-box: Scheduling logic (weekday/weekend/holiday/already contacted)
#   - Black-box: VAPI call delivery (success/failure/missing config)
#   - Black-box: SMS fallback (success/disabled)
#   - Black-box: End-to-end integration (generation + delivery)
#   - White-box: Content aggregation (tasks/metrics/alerts/opportunities)
#   - White-box: Template rendering (voice script/text summary/storage format)
#   - White-box: Cleanup logic (old briefings)
# Edge Cases Covered:
#   - No tasks pending
#   - All systems healthy
#   - Multiple alerts
#   - Missing configuration
#   - VAPI call failures
#   - Old briefing cleanup
