Phase 1 — Token Foundation & Adoption (Week 1–2)

Goal: Every web app consumes tokens from @bytelyst/design-tokens. Zero hand-written CSS custom properties. Token Foundation 95% → 100%, Token Adoption (Web) 72% → 95%.

Estimated effort: 4–5 days

1.1 Add Missing Product Palettes to Canonical JSON

4 products have no palette in bytelyst.tokens.json. Add them so the generator can produce per-product CSS.

• ActionTrail — add color.actiontrail section (accent, danger, surface variants) to bytelyst.tokens.json
• NoteLett — add color.notelett section
• LocalMemGPT — add color.localmemgpt section
• Local LLM Lab — add color.localllmlab section
• Run generate.ts and verify 4 new CSS + Swift + Kotlin files appear in generated/

Files: packages/design-tokens/tokens/bytelyst.tokens.json, packages/design-tokens/scripts/generate.ts

1.2 Generate Per-Product CSS and Wire Into Web Apps

The generator already produces per-product files. Each web app should import the generated CSS instead of hand-writing globals.css token blocks.

• Publish @bytelyst/design-tokens generated output to Gitea npm registry (or use file: ref)
• ChronoMind — replace hand-written --cm-* block in globals.css with @import '@bytelyst/design-tokens/generated/css/chronomind.css'
• JarvisJr — replace --jj-* block
• NomGap — replace --ng-* block; remove leaked --ml-* references
• ActionTrail — replace --at-* block
• FlowMonk — replace --fm-* block
• NoteLett — replace --nl-* block; remove leaked --ml-* references
• LocalMemGPT — replace --lmg-* block
• Local LLM Lab — replace --llm-* block
• Verify each app still renders correctly after swap (visual spot-check)

Files per app: web/src/app/globals.css, package.json (add dep)

1.3 Fix NomGap + NoteLett Token Prefix Leaks

Both apps leak --ml-* MindLyst tokens into their CSS.

• NomGap web globals.css — find and replace all --ml-* references with --ng-*
• NoteLett web globals.css — find and replace all --ml-* references with --nl-*
• Grep-verify: grep -rn '\-\-ml-' web/src/ returns 0 hits in both repos

1.4 Commit & Push

• Commit per-repo: fix(tokens): consume @bytelyst/design-tokens instead of hand-written CSS
• Push all repos to origin

Phase 1 Score Impact

Dimension	Before	After
Token Foundation	95%	100%
Token Adoption (Web)	72%	95%
Overall	65%	72%

Phase 2 — Shared Component Library (Week 2–4)

Goal: Create @bytelyst/ui with 12 shared primitives. Integrate shadcn/ui as the foundation. Component Library 15% → 70%.

Estimated effort: 8–10 days

2.1 Scaffold @bytelyst/ui Package

• Create packages/ui/ in learning_ai_common_plat
• Initialize with package.json (@bytelyst/ui), tsconfig.json, Vitest
• Add react, react-dom, tailwindcss, class-variance-authority, clsx, tailwind-merge as peer deps
• Add lucide-react as peer dep (standardize icon library)
• Configure exports: @bytelyst/ui/button, @bytelyst/ui/input, etc.
• Add README.md with usage examples

2.2 Integrate shadcn/ui Primitives

Use Radix UI primitives (via shadcn/ui patterns) for accessible, composable components.

• Add @radix-ui/react-dialog, @radix-ui/react-toast, @radix-ui/react-select, @radix-ui/react-dropdown-menu, @radix-ui/react-tooltip
• Create cn() utility (clsx + tailwind-merge)
• Configure Tailwind to consume @bytelyst/design-tokens CSS vars

2.3 Build 12 Core Components

Each component must: use design tokens, support dark/light, have ARIA, have focus-visible, be documented.

#	Component	Priority	Variants	Notes
1	Button	P0	primary, secondary, ghost, destructive, icon-only	aria-label on icon-only
2	Input	P0	text, email, password, search	Error/success states, aria-invalid
3	Modal/Dialog	P0	alert, confirm, form	Focus trap, Esc close, aria-modal
4	Toast	P0	success, error, warning, info	Auto-dismiss, role="alert"
5	Card	P0	default, elevated, interactive	Hover state on interactive
6	Badge	P1	status, count, risk-level	Color-coded by semantic tokens
7	Select	P1	single, multi	Radix Select, keyboard nav
8	Sidebar	P1	collapsible, responsive	<aside> + <nav> landmark
9	EmptyState	P1	with icon, with action	Illustration + CTA button
10	LoadingSpinner	P1	spinner, skeleton, bar	aria-busy, prefers-reduced-motion
11	StatCard	P2	number, trend, sparkline	Used in dashboards
12	ConfirmDialog	P2	destructive, standard	Extends Modal with confirm/cancel

• Build and test each component (Vitest + visual review)
• Export all from package index

2.4 Adopt @bytelyst/ui in 3 Pilot Apps

Start with the 3 apps that have the most UI surface area.

• ChronoMind web — replace inline Button, Toast, Modal with @bytelyst/ui
• NomGap web — replace inline components
• LocalMemGPT web — replace inline components
• Verify builds pass, visual spot-check

2.5 Roll Out to Remaining Apps

Goal: Dark/light toggle in all apps, responsive layouts, toast feedback, loading states. Dark/Light 55% → 85%, Responsive 5% → 60%, UX Patterns 72% → 85%.

Estimated effort: 7–8 days

4.1 Dark/Light Theme Toggle (5 Apps)

Only LocalMemGPT, ChronoMind, and MindLyst have toggles. Add to 5 more.

• Create shared useTheme hook in @bytelyst/ui (localStorage persistence, prefers-color-scheme default)

• LocalMemGPT — add toast on conversation create/delete, document upload
• LLM Lab — add toast on conversation create/delete, model switch

4.4 Loading States for All Async Operations

• Ensure every fetch / useEffect data load shows a loading state
• Use @bytelyst/ui/LoadingSpinner or skeleton
• Focus apps: ChronoMind, JarvisJr, NoteLett (currently minimal loading refs)

4.5 Empty States for All List Views

~5 total empty state refs across 7 apps. Every list should have an empty state.

• Use @bytelyst/ui/EmptyState component
• Add to: timer list, session list, agent list, task list, note list, conversation list, document list
• Include icon + descriptive text + CTA button

4.6 NomGap RN — Eliminate Remaining Hardcoded Hex

337 hardcoded hex values in NomGap mobile. The theme system exists but isn't consumed everywhere.

• Run grep -rn '#[0-9A-Fa-f]\{6\}' src/screens/ src/components/ to get full list
• Replace each with colors.xxx from useTheme() hook
• Priority files: JourneyScreen.tsx, NotificationSettings.tsx, BodyVisualization/*
• Target: <20 remaining (some are SVG/canvas constants that can't use theme)

4.7 Commit & Push

• Commit per-repo: feat(web): add theme toggle, responsive layout, toast feedback, empty states

Phase 4 Score Impact

Dimension	Before	After
Dark/Light Theme	55%	85%

• Create shared a11y.spec.ts template: load each major page, run checkA11y(), assert 0 violations
• Wire into Gitea CI workflow (ci.yml) as a required step
• Fix any violations found

5.2 Visual Regression Testing

• Add Playwright screenshot comparison to each repo
• Create visual-regression.spec.ts with screenshots of: dashboard, settings, main list view
• Store baseline screenshots in e2e/__screenshots__/
• Wire into CI: fail on >0.5% pixel diff

5.3 Token Drift CI Check

• Create scripts/check-token-drift.sh in common-plat
• Script: re-run generate.ts, diff output against committed files, fail if drift detected
• Add to common-plat CI workflow
• Document in AGENTS.md

5.4 Storybook for @bytelyst/ui

• Add @storybook/react + @storybook/addon-a11y to packages/ui/
• Create .storybook/ config with Tailwind + design tokens
• Write stories for all 12 components (variants, states, dark/light)
• Add storybook script to package.json
• Optional: deploy to static hosting for team review

5.5 Design Review PR Template

• Create .github/pull_request_template.md in common-plat and all product repos
• Template requires: screenshot (before/after), a11y checklist, mobile viewport check
• Include checkboxes: [ ] Uses design tokens, [ ] Has focus-visible, [ ] Has ARIA labels

5.6 Update AGENTS.md Across All Repos

• Add @bytelyst/ui to tech stack tables
• Add design system rules: "Must use @bytelyst/ui components — never build from scratch"
• Add a11y rules: "Every interactive element must have aria-label or visible text"

5.7 Final Audit Report Update

• Re-run full workspace scan
• Update DESIGN_SYSTEM_AUDIT.md Appendix H with final scores
• Commit: docs(audit): final design system audit — 100% remediation complete

Dependencies & Risks

Risk	Mitigation
@bytelyst/ui takes longer than estimated	Start with 6 P0 components, defer P2 to later sprint
NomGap RN hex replacement breaks screens	Run full test suite (npm test — 505 tests) after each batch
Responsive sidebar breaks existing layouts	Feature-flag the responsive behavior; ship behind RESPONSIVE_SIDEBAR flag
axe-core finds many contrast failures	Fix critical (4.5:1 text) first, defer non-critical (3:1 decorative)
Common-plat Storybook adds build complexity	Keep Storybook as dev-only dependency, not part of production build

Quick Wins (Can Be Done Independently)

These items can be tackled at any time without blocking other phases:

• Add not-found.tsx + error.tsx + loading.tsx to all 7 apps (30 min per app)
• Add :focus-visible CSS rule to 6 apps missing it (5 min per app)
• Add Lucide icons to ActionTrail + FlowMonk (currently no icon library)
• Fix NomGap web 117 hardcoded hex in components (2–3 hours)
• Fix FlowMonk 29 hardcoded hex in CSS (1 hour)
• Fix LLM Lab 31 hardcoded hex in CSS (1 hour)

---
