[PRJ-02-VALIDATE] Project Validation: Project 02

[Rick1330]

Project

• ID: PRJ-02
• Title: Design System & Application Shell

---

Transition Truth

• Current apps/web on main remains a temporary static placeholder surface deployed on Vercel.
• This validation issue stays blocked until the prerequisite platform-transition issue #1508 lands and the PRJ-02 stories have a real frontend foundation to validate against.
• The validation commands below describe the eventual target-state check surface, not the current placeholder on main.

Child Stories

• CS-009 — As a new user I want to see a landing page with feature highlights so that I understand what CollabSphere offers
• CS-010 — As a workspace member I want consistent light/dark/system theme options so that I can reduce eye strain
• CS-011 — As a workspace member I want a responsive top navigation bar with workspace switcher so that I can navigate between contexts
• CS-012 — As a workspace member I want a collapsible left sidebar with workspace navigation so that I can access all features quickly
• CS-013 — As a workspace member I want command palette access via Cmd+K so that I can navigate without using a mouse
• CS-014 — As a workspace member I want keyboard shortcuts for common actions so that I can work more efficiently
• CS-015 — As a workspace member I want consistent loading, empty, error, and loaded states on all pages so that I understand system status
• CS-016 — As a workspace member I want accessible UI components meeting WCAG 2.1 AA so that I can use the platform with assistive technology
• CS-017 — As a workspace member I want breadcrumb navigation showing my location so that I can traverse the hierarchy easily
• CS-018 — As a workspace member I want mobile-responsive layouts for tablet and phone so that I can view content on any device

Success Metrics

• Local axe audits show zero critical violations on core UI surfaces — pending
• Theme switching completes in <100ms with no flash of unstyled content (FOUC) — pending
• Navigation components render correctly at all breakpoints (320px-1920px+) in manual responsive checks — pending
• New feature development time reduced by 30% using design system components (measured via sprint velocity) — pending

---

Exit Criteria

• Project validation artifact complete with evidence — pending
• Prerequisite platform transition complete — pending
• All Stories Done — pending
• Demo flow documented (design system usage guide with component examples) — pending
• Staging verified (manual breakpoint checks at 320px-1920px+) — pending
• Stakeholder sign-off (design + engineering lead approval on component API and accessibility) — pending

Validation Categories

• functional-readiness
• performance-readiness
• security-readiness
• operational-readiness
• downstream-readiness
• contributor-readiness

Validation Steps / Commands

pnpm -w lint
pnpm --filter web test
pnpm --filter web build
# Manual: run accessibility audit (axe) on core pages
# Manual: verify responsive behavior across breakpoints (including 1920px+)
# Manual: verify theme switching, command palette, and keyboard shortcuts

Expected outcomes:

• Lint and tests pass without errors.
• App shell renders with consistent layout, states, and navigation.
• Accessibility checks show no critical violations.
• Responsive behavior matches spec across mobile/tablet/desktop.
