"""
Cross-Session Memory Service (Phase 3)

Provides persistent patient/session context that survives across
multiple encounters. Uses Redis for fast session cache and PostgreSQL
for durable long-term memory.

Memory types:
- **Session cache**: Active session state (Redis, TTL-based)
- **Patient history**: Cross-encounter summaries (PostgreSQL)
- **Entity memory**: Accumulated conditions/medications per patient
- **Preference memory**: Patient communication preferences, language
