"""Integration tests for Memory CRUD, Channel auto-start, Knowledge, and Cron features.

Tests cover the specific fixes made in this session:
- Memory: store, list, get, delete, clear — all syncing with SDK
- Channels: add, auto-start flag, persistence
- Cron/Schedules: add, run history with result, toggle, delete

Run with:
    PYTHONPATH=src python3 -m pytest tests/integration/test_fixed_features.py -v -o "addopts=" --timeout=30
