- Motion System v1:
- Renamed duration tokens from time-based (fast/slow) to intention-based
(instant, interaction, transition, navigation, layout, context-change,
attention, background)
- Updated all component motion tables to use intention-based tokens
- Rationale: AI reasons about purpose, not milliseconds
- Button gold standard (chapter 8.3.1):
- Added RFC-level sections: Cognitive Purpose, When to use/NOT use,
User Expectation, Interaction Contract, Failure Behaviour,
Accessibility Contract, AI Contract
- Sets the bar for all future component specifications
- AI_DESIGN_PRINCIPLES.md (v1.0, LOCKED):
- Core principle: AI must be a design system citizen
- Before-action rules: read hierarchy, check existing, apply New Component Rule
- Token rules: no hardcoded values, semantic first, lifecycle, deterministic
- Component rules: inheritance first, use template, document anti-patterns
- Motion rules: intention-based duration, reduced motion, no decorative animation
- Accessibility rules: WCAG 2.1 AA, no ARIA without purpose
- AI Contract for Button: when to choose Button vs Link vs Icon Button
- RELEASE_DEFINITION.md:
- Defines Landvex Design System v1.0 release gates
- Foundation, Tokens, Foundations, Components (Tier 1/2/3),
Validation, Production
- Current progress: ~55%
- Next milestones: Grid+Elevation, Input/Select/Card, Brand Palette
Rationale: AI rules before components (AI will write components).
Intention-based motion tokens for better AI reasoning. Button as RFC
sets the standard. Release definition creates clear target.
