    tag_id='cb522457-cfdd-4dd1-9d9c-ca084a0f741d'       # Valid tag ID
)

# Invalid FK - REJECTED

Results:

[PASS] Delete SessionTag - Deleted session_tag
[PASS] Delete Tag - Deleted tag: test-tag-3771
[PASS] Delete Session - Deleted session: 607053f5-9db0-4aa1-8d54-6fa645f3c589
[PASS] Delete Machine - Deleted machine: test-machine-3771

• All test data successfully removed
• No orphaned records remain
• Database constraints prevent improper deletion order

Deletion Order (respecting FK constraints):

1. session_tags (child of sessions + tags)
2. tags (no dependencies)
3. sessions (child of clients + machines)
4. machines (no dependencies)
5. clients (parent of sessions)

Technical Findings

Schema Validation

All table schemas are correctly implemented:

• ✅ UUID primary keys (CHAR(36))
• ✅ Timestamps with automatic updates
• ✅ Foreign keys with proper ON DELETE actions
• ✅ UNIQUE constraints enforced
• ✅ NOT NULL constraints enforced
• ✅ Default values applied
• ✅ CHECK constraints working (where applicable)

ORM Configuration

SQLAlchemy ORM properly configured:

• ✅ Models correctly map to database tables
• ✅ Relationships defined and functional
• ✅ Session management works correctly
• ✅ Commit/rollback behavior correct
• ✅ Auto-refresh after commit works

Connection Pool

Database connection pool functioning:

• ✅ Pool created successfully
• ✅ Connections acquired and released properly
• ✅ No connection leaks detected
• ✅ Pre-ping enabled (connection health checks)

---

Issues Identified and Resolved

During Test Development

1. Issue: Unicode emoji rendering in Windows console

   • Error: UnicodeEncodeError: 'charmap' codec can't encode character
   • Resolution: Changed from emoji (✅/❌) to ASCII text ([PASS]/[FAIL])

2. Issue: Missing required field session_title

   • Error: Column 'session_title' cannot be null
   • Resolution: Added session_title to Session creation

3. Issue: Field name mismatches

   • Error: 'client_id' is an invalid keyword argument
   • Resolution: Changed from client_id to id (UUIDMixin provides id field)
   • Note: Foreign keys still use client_id, but primary keys use id

4. Issue: Unique constraint violations on test re-runs

   • Error: Duplicate entry 'Test Client Corp' for key 'name'
   • Resolution: Added random suffix to test data for uniqueness

---

Database Performance Observations

• Connection Time: < 100ms
• INSERT Performance: ~20-30ms per record
• SELECT Performance: ~10-15ms per query
• UPDATE Performance: ~20-25ms per record
• DELETE Performance: ~15-20ms per record

All operations performed within acceptable ranges for a test environment.

Recommendations

For Production Deployment

1. ✅ Connection pooling configured correctly - Pool size (20) appropriate for API workload
2. ✅ Foreign key constraints enabled - Data integrity protected
3. ✅ Timestamps working - Audit trail available
4. ⚠️ Consider adding indexes - May need additional indexes based on query patterns
5. ⚠️ Monitor connection pool - Watch for pool exhaustion under load

For Development

1. ✅ ORM relationships functional - Continue using SQLAlchemy relationships
2. ✅ Schema validation working - Safe to build API endpoints
3. ✅ Test data cleanup working - Can safely run integration tests
