Template:
IF [condition/action]
THEN [expected buggy behavior]
BECAUSE [root cause theory]

Example:
IF rapid terminal creation requests are made
THEN duplicate terminals may be created
BECAUSE there is no atomic lock on the creation operation

// Design test to confirm hypothesis
describe('Bug Hypothesis: Rapid terminal creation causes duplicates', () => {
  it('should handle concurrent creation requests', async () => {
    const manager = new TerminalManager();

    // Trigger the suspected bug condition
    const results = await Promise.all([
      manager.createTerminal(),
      manager.createTerminal(),
      manager.createTerminal()
    ]);

    // Verify expected behavior
    const uniqueIds = new Set(results.map(t => t.id));
    expect(uniqueIds.size).toBe(results.length);
