1. Root Cause Analysis

The issue occurs because payload parsing assumes minimum buffer bounds without checked additions, leading to index out-of-bounds panics or excessive allocation cycles under heavy concurrency.

describe('Fix #1 Regression', () => {
  it('should handle truncated and edge-case inputs gracefully without throwing', async () => {
    const result = executeSafeLogic(invalidPayload);
    expect(result.success).toBe(false);
    expect(result.error).toBeDefined();
  });
});
