- **Removed Files**: - Deleted outdated statistics documentation files (`statistics.md`, `statistics-flush-solution.md`, `statistics-summary.md`) to clean up the repository and avoid confusion. - **Added Standards**: - Introduced `DOCUMENTATION_STANDARDS.md` to outline naming conventions and troubleshooting practices for more consistent and maintainable project documentation. - **Tests**: - Added a new test file `edge-cases.test.ts` to verify handling of edge cases, ensuring robust behavior against boundary values and invalid inputs. **Purpose**: Cleans up deprecated documentation while introducing concrete standards for maintaining and updating documentation. Enhances test coverage for unusual or boundary inputs, improving overall system resilience.

/**
|
|
* Edge Case Tests
|
|
*
|
|
* Purpose:
|
|
* This test suite verifies that the Brainy API properly handles edge cases, including:
|
|
* 1. Empty queries
|
|
* 2. Invalid IDs
|
|
* 3. Zero-length vectors
|
|
* 4. Dimension mismatches
|
|
* 5. Maximum/minimum values
|
|
* 6. Special characters in text
|
|
*
|
|
* These tests ensure the library is robust when used with boundary values
|
|
* and unusual inputs.
