CUBRID Isolation Test Creator & Runner

Create .ctl isolation tests that verify MVCC visibility, lock conflicts, and concurrent transaction behavior using CUBRID's CTP isolation test framework. Tests are run via the qactl/qacsql tools with deterministic multi-client orchestration.

When to Use

• User asks to test isolation, concurrency, MVCC, or locking behavior
• User mentions "isolation test", ".ctl test", "concurrent access test"
• After implementing a storage/transaction feature that affects multi-session behavior
• When verifying MVCC snapshot visibility for a feature (e.g., OOS, overflow, new column types)
