Changelog

Cognition version history. What shipped, what changed, and what the system has become.

Cognition is currently in development. Goal is production infrastructure for Distyl AI, distributed as a versioned skill across the team's AI toolchain.

v1.3 · June 2026
Cognition v1.3
Current
Full component coverage. Codebase audit complete. System and Language distinction established. Skill distributed via ai-tools.
  • 60+ components documented and live: all shadcn primitives plus Conversational UI, Graph Canvas Node, Charts, Field, Item, Spinner, and more
  • Full sitewide compliance pass: em dashes removed from prose across all 19 component pages, Radix references removed from user-facing copy, ChatShell inline style replaced with utility class
  • Cognition skill rewritten as an agent briefing: distributed via ai-tools for use in Claude Code, Cursor, Copilot, and Windsurf
  • System vs Language distinction established: Cognition is the token and component infrastructure; the Language (Pro Blocks, motion, app shells, opinionated patterns) builds on top
  • Roadmap expanded to 10 epics: Motion Foundations, ApiTable component, API accuracy pass, and Docs site copy sweep added
  • Governance model defined: token changes versioned, all proposals go through design before landing
  • New FE architect onboarded: system greenlit as platform infrastructure

  • Graph Canvas Node: domain-color system, approved patterns documented (colored header band, sentence-case label)
  • Token drift guard: scripts/check-tokens.mjs gates production deploys on color token violations
  • Sessions 1 through 7 complete and committed
  • All component pages verified on production at design.distyl.ai
  • Spinner animation rule established: rotate only, no stroke-dashoffset
  • react-day-picker v9 adopted (v8 deprecated)
  • Navigation Menu and Toast variant card exceptions documented
v1.1 · May 2026

v1.0 · April 2026
Cognition v1.0
Foundation
Foundation. Built from scratch in two days: token architecture, component library, and docs site scaffold.
  • Three-layer token architecture: primitives, semantic, and component tokens, all in globals.css inside @theme {}
  • Tailwind v4 adopted: no tailwind.config.js, all tokens as CSS custom properties
  • shadcn/ui as component foundation, Radix UI primitives via components/ui/ wrappers
  • Brand color established: #5D4EE7 (purple)
  • Geist (UI) and Geist Mono (code) as system fonts
  • CLAUDE.md and .cursorrules created for AI tool context
