2021–2026 · Algorithm and data structure expansion
This period focused on expanding the library's algorithmic and data structure coverage by introducing new implementations for board tiling, K-D trees, edit distance, and various mathematical functions. Concurrently, significant effort was directed toward improving test coverage across these new and existing components, including the addition of unit tests for skip lists, dynamic arrays, and math utilities.

About this page
- The description of this project is derived from its own commit history, not from its README.
- The score is its highest published measurement, taken on 1 August 2026 at a pinned commit. It is not a live figure and does not change until the project is measured again.
- Measured at commit 08c6d5f3cb — the exact code this score is about.
- Scored under rubric rubric-2026.08.18. Score the same commit under that rubric and you get the same number.
