Key Principles

“What you see in git log --graph is what you see in the viewer.” — Terminal-Document Trust Contract
“The Brick guarantees: Terminal —> Document —> Trust.” — CodexMono Foundation Principle
“Equal steps in lightness produce equal perceived brightness changes.” — OKLab Perceptual Uniformity

Summary:
  • Diff Viewer: Unified and side-by-side views with word-level diff and AI attribution
  • Commit Viewer: Complete commit details with interactive file navigation
  • Branch Diagram: Time-based heatmap, OKLab colors, merge visualization, impact scores
  • CodexMono: Typography bridge ensuring Terminal-to-Document visual consistency

“The Brick extends from Terminal to Document: What aligns in git output MUST align in visualization.”
