+```
+
+**Total Time: ~90 minutes**
+
+---
+
+### Workflow 2: Review POC Design for Compliance
+
+**When to Use:** Developer has POC design that needs design system integration
+
+#### Step 1: Analyze POC Design (10 min)
+```
+[ ] Review POC screenshots or code
+[ ] Identify all colors used
+[ ] List all typography styles
+[ ] Note spacing patterns
+[ ] Check icon usage
+[ ] Document violations
+```
+
+#### Step 2: Map to Design System (15 min)
+
+**Create mapping table:**
+
+| POC Element | POC Value | Design System Token | Notes |
+|-------------|-----------|---------------------|-------|
+| Background | #1A2234 | UiColors.background | Exact match |
+| Primary button | #3498DB | UiColors.primary | Close match |
+| Title text | 24px Bold | UiTypography.headlineMedium | Size matches |
+| Body text | 16px Regular | UiTypography.bodyLarge | Exact match |
+| Card padding | 20px | UiConstants.paddingMedium (16dp) | Adjust to 16dp |
+| Icon | Custom SVG | UiIcons.search | Replace with token |
+
+#### Step 3: Generate Compliance Report (10 min)
+
+```markdown
+## POC Design Compliance Report
+
+### Summary
+- ✅ Color usage: 80% compliant (4/5 colors)
+- ⚠️ Typography: 90% compliant (9/10 styles)
+- ❌ Spacing: 60% compliant (3/5 values)
+- ❌ Icons: 40% compliant (2/5 icons)
+- **Overall:** ⚠️ NEEDS ADJUSTMENT
+
+### Required Changes
+
+#### Colors
+1. ✅ Background #1A2234 → UiColors.background (already matches)
+2. ⚠️ Accent #FF6B6B → No exact match, use UiColors.error for error states, UiColors.primary for accents
+3. ✅ Text #FFFFFF → UiColors.onPrimary (matches)
+
+#### Typography
+1. ✅ Title 24px Bold → UiTypography.headlineMedium (matches)
+2. ❌ Subtext 14px Regular → Use UiTypography.bodyMedium (16px) for consistency
+
+#### Spacing
+1. ❌ Card padding 20px → UiConstants.paddingMedium (16dp)
+2. ❌ Item gap 12px → UiConstants.paddingSmall (8dp) or paddingMedium (16dp)
+3. ✅ Screen margin 16px → UiConstants.paddingMedium (matches)
+
+#### Icons
+1. ❌ Custom search icon → UiIcons.search
+2. ❌ Custom user icon → UiIcons.person
+3. ✅ Material Icons check → UiIcons.check (already using)
+
+### Implementation Priority
+**High Priority (must fix):**
+- Replace custom icons with UiIcons
+- Adjust spacing to design system values
+
+**Medium Priority (should fix):**
+- Update accent color usage
+- Fix typography sizes
+
+### Estimated Refactor Time
+2-3 hours for full compliance
+```
+
+#### Step 4: Create Compliant Version in Paper (20 min)
+
+Use Paper MCP to create corrected version following design system.
+
+#### Step 5: Handoff Corrected Design (5 min)
+
+Share Paper link and compliance report with Mobile Feature Agent.
+
+---
+
+### Workflow 3: Design System Audit
+
+**When to Use:** Periodic audit of existing features for violations
+
+#### Step 1: Scan Codebase for Violations (15 min)
+
+**Automated checks:**
+
+```bash
+# Find hardcoded colors
+grep -r "Color(0x" apps/mobile/apps/*/lib/ > /tmp/color-violations.txt
+
+# Find custom TextStyle
+grep -r "TextStyle(" apps/mobile/apps/*/lib/ > /tmp/typography-violations.txt
+
+# Find hardcoded spacing
+grep -r -E "EdgeInsets\.(all|symmetric|only)\([0-9]+" apps/mobile/apps/*/lib/ > /tmp/spacing-violations.txt
+
+# Count violations
+wc -l /tmp/*-violations.txt
+```
+
+#### Step 2: Create Violation Report (10 min)
+
+```markdown
+## Design System Audit Report - March 2026
+
+### Violations Found
+
+#### Color Violations: 12 instances
+- `features/profile/screens/profile_screen.dart:45` - Color(0xFF1A2234)
+- `features/jobs/widgets/job_card.dart:78` - Color(0xFF3498DB)
+- ...
+
+#### Typography Violations: 8 instances
+- `features/shifts/screens/shift_details.dart:92` - TextStyle(fontSize: 18)
+- ...
+
+#### Spacing Violations: 15 instances
+- `features/dashboard/widgets/stat_card.dart:34` - EdgeInsets.all(20)
+- ...
+
+### Prioritization
+**Critical (block future releases):**
+- Jobs feature (5 violations)
+- Profile feature (4 violations)
+
+**Medium (fix in next sprint):**
+- Dashboard feature (3 violations)
+
+**Low (nice to have):**
+- Settings feature (2 violations)
+
+### Remediation Plan
+1. Week 1: Fix critical violations in jobs and profile
+2. Week 2: Fix medium violations in dashboard
+3. Week 3: Address low priority violations
+
+### Prevention
+- Enable Architecture Review Agent pre-merge
+- Add pre-commit hooks for violations
+- Update developer onboarding to emphasize design system
+```
+
+#### Step 3: Create Remediation Tickets
+
+For each violation cluster, create issues:
+
+```markdown
+**Title:** [Design System] Fix color violations in profile feature
+
+**Description:**
+Profile feature has 4 hardcoded color instances that need migration to UiColors.
+
+**Violations:**
+1. `profile_screen.dart:45` - Color(0xFF1A2234) → UiColors.background
+2. `profile_header.dart:78` - Color(0xFF3498DB) → UiColors.primary
+...
+
+**Acceptance Criteria:**
+- [ ] All colors replaced with UiColors tokens
+- [ ] Tests still pass
+- [ ] Visual appearance unchanged
+- [ ] Architecture Review Agent approves
+
+**Estimated Effort:** 1 hour
+```

+## 🤝 Handoff Criteria
+
+### When to Escalate to Human
+
+Escalate when you encounter:
+
+1. **Design System Gaps**
+   - Required color not in UiColors
+   - Typography style combination needed
+   - Icon not available in UiIcons
+   - New component pattern needed
+
+2. **Accessibility Conflicts**
+   - Contrast ratio requirements conflict with brand colors
+   - Touch target size conflicts with dense layouts
+   - Complex interactions hard to make accessible
+
+3. **Technical Constraints**
+   - Design requires platform capabilities not available
+   - Performance concerns with proposed design
+   - Animation complexity beyond Flutter capabilities
+
+4. **Business Decisions**
+   - Multiple design approaches possible, unclear priority
+   - Stakeholder feedback conflicts
+   - Budget/time constraints affecting design scope
+
+5. **Branding Questions**
+   - Design decision affects brand identity
+   - New visual direction needed
+   - Cross-platform consistency concerns
