"""
Integration tests for ALL 17 memory handlers.

Regression prevention for Issue #299 (import errors) and #300 (response format).
Ensures 100% handler coverage to catch bugs before production.

Coverage:
- 3 existing handlers (store, retrieve, search_by_tag) - ✓ Already tested
- 14 untested handlers - NEW comprehensive coverage

Response Format Validation:
- All handlers return List[types.TextContent]
- No KeyError on result["message"] (Issue #300)
- Proper success/error parsing (result["success"], result["error"])

Import Validation:
- Tests run without mocks (real imports)
- Validates normalize_tags import (Issue #299)
- Catches ImportError before production
