"""
smoke_test.py — Phase 0-4 verification (no live API calls).

Verifies:
  1.  Config loads without errors
  2.  Database initialises and migrations run
  3.  CredentialStore: write, read-back after re-init, delete
  4.  AuditLog: write an entry and query it back
  5.  Kill switch: pause → check → resume → check
  6.  Security: whitelists, path enforcement, injection sanitizer
  7.  Provider registry: at least one provider configured
  8.  Tool registry: all 5 production tools register without error
  9.  Confirmation flow: asyncio Event round-trip
  10. Phase 2 tools instantiate correctly
  11. Tool-level security (filesystem sandbox, email whitelist, web tiers)
  12. Phase 3 web interface: HTML pages and REST API endpoints
  13. Phase 4 scheduler: task CRUD, toggle, run endpoint, APScheduler cron parse

Run from the project root:
    python smoke_test.py
