// To re-enable tests for loadHierarchicalGeminiMemory, ensure that:

// 2. fs/promises and fs mocks correctly simulate file/directory existence,
// readability, and content based on paths derived from the mocked os.homedir().
// 3. Spies on console functions (for logger output) are correctly set up if needed.
// Example of a previously failing test structure:
