How it got here

2018–2019 · Platform-specific feature expansion and architecture modernization

This period focused on deepening platform-specific capabilities, introducing new canvas primitives, layout managers, and desktop integrations like system trays and accessibility bridges. The codebase was modernized by removing legacy interfaces, refactoring the internal painter for hardware and software rendering, and expanding mobile build support.

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 6 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 eac48f3012 — the exact code this score is about.
  • Scored under rubric rubric-2026.08.19. Score the same commit under that rubric and you get the same number.
