Summary

Implement a system to gate features and functions behind user tiers (Free, Pro, Enterprise). This provides the foundation for monetization and premium feature differentiation.

User Tiers

Tier Description
free Default tier, limited features
pro Mid-tier, most features
enterprise Full access to all features

Requirements

Database

  • Add tier column to users table if not present (enum: free, pro, enterprise, default: free)
  • Create migration for the schema change

Backend - Feature Registry

  • Create backend/src/config/feature-tiers.ts - hardcoded feature-to-tier mapping
  • Structure should support:
    • Feature key (e.g., document.scanMaintenanceSchedule)
    • Minimum required tier
    • Optional metadata (description, upgrade prompt text)

Example structure:

export const FEATURE_TIERS = {
  'document.scanMaintenanceSchedule': {
    minTier: 'pro',
    name: 'Scan for Maintenance Schedule',
    upgradePrompt: 'Upgrade to Pro to automatically extract maintenance schedules from your manuals.'
  }
} as const;

Backend - Tier Enforcement

  • Create tier utility service with:
    • canAccessFeature(userTier: Tier, featureKey: string): boolean
    • getRequiredTier(featureKey: string): Tier
    • getTierLevel(tier: Tier): number (for comparison: free=0, pro=1, enterprise=2)
  • Add middleware/decorator for route-level tier checks
  • Return 403 with structured error when tier insufficient:
{
  "error": "TIER_REQUIRED",
  "requiredTier": "pro",
  "currentTier": "free",
  "feature": "document.scanMaintenanceSchedule",
  "upgradePrompt": "..."
}

Frontend - Tier Context

  • Add user tier to auth context (should already be returned from /api/auth/me)
  • Create useTierAccess hook:
    • hasAccess(featureKey: string): boolean
    • checkAccess(featureKey: string): { allowed: boolean; requiredTier?: Tier }

Frontend - Upgrade Dialog

  • Create reusable UpgradeRequiredDialog component
  • Props: featureKey, open, onClose
  • Display: Feature name, current tier, required tier, upgrade prompt
  • Action button: "Upgrade" (placeholder for future Stripe integration - can link to a coming soon page or just close)
  • Mobile + Desktop responsive

Admin UI Integration

  • Integrate tier management into existing Admin UI screen
  • Admin should be able to view/change user tiers

Initial Feature Gate

  • Gate "Scan for Maintenance Schedule" checkbox on document upload:
    • Frontend: Show checkbox only for Pro+ OR show disabled with lock icon that opens upgrade dialog on click
    • Backend: Validate tier before processing scan request

Technical Notes

  • Extensibility: Adding new gated features should only require:
    1. Add entry to feature-tiers.ts
    2. Add frontend check using useTierAccess hook
    3. Add backend check on relevant endpoint
  • Tier hierarchy: enterprise > pro > free (higher tiers inherit all lower tier features)
  • Future: Stripe integration will be a separate issue

Acceptance Criteria

  • Free users see upgrade dialog when attempting to use "Scan for Maintenance Schedule"
  • Pro and Enterprise users can use "Scan for Maintenance Schedule" normally
  • Backend returns 403 with proper error structure if Free user bypasses frontend
  • Adding a new gated feature requires only config + UI changes (no structural changes)
  • Admin can change user tiers from Admin UI
  • All components work on mobile and desktop
  • Tests cover tier checking logic

Out of Scope (Future Issues)

  • Stripe billing integration
  • Subscription expiration handling

Implementation Plan - User Tier-Based Feature Gating

Analysis Summary

Codebase Analysis Complete. Key findings:

Component Status Notes
subscription_tier column EXISTS In user_profiles table (migration 002)
SubscriptionTier type EXISTS Both frontend and backend
Admin tier change UI EXISTS AdminUsersPage.tsx dropdown works
scanForMaintenance column EXISTS In documents table (migration 002)
Feature gating infrastructure MISSING No middleware, no frontend hook

Files to Create (4):

  • backend/src/config/feature-tiers.ts
  • backend/src/core/plugins/tier-guard.plugin.ts
  • frontend/src/core/hooks/useTierAccess.ts
  • frontend/src/shared-minimal/components/UpgradeRequiredDialog.tsx

Files to Modify (4):

  • backend/src/core/plugins/auth.plugin.ts (add tier to userContext)
  • backend/src/features/documents/domain/documents.service.ts (validate tier)
  • frontend/src/features/documents/components/DocumentForm.tsx (gate checkbox)
  • Type definition files for tier context

Milestone 1: Backend Feature Registry and Tier Service

Goal: Create centralized feature-to-tier configuration and utility functions.

Files:

File Action Description
backend/src/config/feature-tiers.ts CREATE Feature registry with tier mapping

Implementation:

// Tier hierarchy: free=0, pro=1, enterprise=2
export const TIER_LEVELS = { free: 0, pro: 1, enterprise: 2 } as const;

export const FEATURE_TIERS = {
  'document.scanMaintenanceSchedule': {
    minTier: 'pro',
    name: 'Scan for Maintenance Schedule',
    upgradePrompt: 'Upgrade to Pro to automatically extract maintenance schedules from your manuals.'
  }
} as const;

// Utility functions
export function getTierLevel(tier: SubscriptionTier): number
export function canAccessFeature(userTier: SubscriptionTier, featureKey: string): boolean
export function getRequiredTier(featureKey: string): SubscriptionTier | null
export function getFeatureConfig(featureKey: string): FeatureConfig | undefined

Tests:

  • feature-tiers.spec.ts - Unit tests for tier comparison logic

Acceptance:

  • FEATURE_TIERS exports with scanMaintenanceSchedule entry
  • getTierLevel returns correct numeric values
  • canAccessFeature returns true for equal/higher tiers
  • Unit tests pass

Milestone 2: Backend Auth Context Extension

Goal: Add subscriptionTier to request.userContext for route-level checks.

Files:

File Action Description
backend/src/core/plugins/auth.plugin.ts EDIT Add tier to userContext

Changes at line ~208:

// Current:
request.userContext = {
  userId, email, displayName, emailVerified, onboardingCompleted,
  isAdmin: false,
};

// After:
request.userContext = {
  userId, email, displayName, emailVerified, onboardingCompleted,
  isAdmin: false,
  subscriptionTier: profile.subscriptionTier || 'free',
};

Type augmentation update:

interface FastifyRequest {
  userContext?: {
    // ... existing fields
    subscriptionTier: SubscriptionTier;
  };
}

Acceptance:

  • subscriptionTier available in request.userContext
  • Defaults to 'free' if profile missing
  • Type definitions updated

Milestone 3: Backend Tier Enforcement Middleware

Goal: Create reusable middleware for route-level tier checks.

Files:

File Action Description
backend/src/core/plugins/tier-guard.plugin.ts CREATE Tier enforcement middleware
backend/src/app.ts EDIT Register tier-guard plugin

Implementation Pattern (following admin-guard.plugin.ts):

fastify.decorate('requireTier', async function(
  minTier: SubscriptionTier,
  featureKey?: string
) {
  return async (request: FastifyRequest, reply: FastifyReply) => {
    await this.authenticate(request, reply);
    if (reply.sent) return;
    
    const userTier = request.userContext?.subscriptionTier || 'free';
    if (!canAccessFeature(userTier, featureKey || minTier)) {
      const config = getFeatureConfig(featureKey);
      return reply.code(403).send({
        error: 'TIER_REQUIRED',
        requiredTier: config?.minTier || minTier,
        currentTier: userTier,
        feature: featureKey,
        upgradePrompt: config?.upgradePrompt
      });
    }
  };
});

Acceptance:

  • requireTier middleware available on fastify instance
  • Returns 403 with structured TIER_REQUIRED error
  • Error includes requiredTier, currentTier, feature, upgradePrompt

Milestone 4: Backend Documents Tier Validation

Goal: Gate scanForMaintenance feature at API level.

Files:

File Action Description
backend/src/features/documents/domain/documents.service.ts EDIT Validate tier
backend/src/features/documents/api/documents.controller.ts EDIT Pass tier context

Service validation:

async createDocument(userId: string, data: CreateDocumentBody, userTier: SubscriptionTier) {
  // Validate tier for scanForMaintenance
  if (data.scanForMaintenance && !canAccessFeature(userTier, 'document.scanMaintenanceSchedule')) {
    throw new ForbiddenError({
      error: 'TIER_REQUIRED',
      requiredTier: 'pro',
      currentTier: userTier,
      feature: 'document.scanMaintenanceSchedule',
      upgradePrompt: FEATURE_TIERS['document.scanMaintenanceSchedule'].upgradePrompt
    });
  }
  // ... continue with creation
}

Tests:

  • Free user with scanForMaintenance=true returns 403
  • Pro/Enterprise user with scanForMaintenance=true succeeds
  • Free user with scanForMaintenance=false succeeds

Acceptance:

  • Free users cannot set scanForMaintenance=true
  • Pro/Enterprise users can set scanForMaintenance=true
  • 403 response matches structured error format
  • Integration tests pass

Milestone 5: Frontend Tier Access Hook

Goal: Create React hook for checking feature access.

Files:

File Action Description
frontend/src/core/hooks/useTierAccess.ts CREATE Tier access hook
frontend/src/core/hooks/index.ts EDIT Export hook

Implementation (following useAdminAccess pattern):

import { useQuery } from '@tanstack/react-query';
import { useAuth0 } from '@auth0/auth0-react';
import { userApi } from '../../features/user-profile/api/user.api';

// Local feature config (mirrors backend)
const FEATURE_TIERS = { /* same as backend */ };

export const useTierAccess = () => {
  const { isAuthenticated, isLoading: authLoading } = useAuth0();
  
  const query = useQuery({
    queryKey: ['userProfile'],
    queryFn: () => userApi.getProfile(),
    enabled: isAuthenticated && !authLoading,
    staleTime: 5 * 60 * 1000,
    gcTime: 10 * 60 * 1000,
  });

  const tier = query.data?.subscriptionTier || 'free';

  return {
    tier,
    loading: query.isLoading,
    hasAccess: (featureKey: string) => canAccessFeature(tier, featureKey),
    checkAccess: (featureKey: string) => ({
      allowed: canAccessFeature(tier, featureKey),
      requiredTier: getRequiredTier(featureKey),
      config: FEATURE_TIERS[featureKey]
    }),
  };
};

Acceptance:

  • Hook returns current tier
  • hasAccess(featureKey) returns boolean
  • checkAccess(featureKey) returns full access info
  • Uses React Query with appropriate caching

Milestone 6: Frontend Upgrade Dialog Component

Goal: Create reusable upgrade prompt dialog.

Files:

File Action Description
frontend/src/shared-minimal/components/UpgradeRequiredDialog.tsx CREATE Dialog component
frontend/src/shared-minimal/components/index.ts EDIT Export component

Props:

interface UpgradeRequiredDialogProps {
  featureKey: string;
  open: boolean;
  onClose: () => void;
}

Implementation (mobile + desktop responsive):

const UpgradeRequiredDialog: React.FC<UpgradeRequiredDialogProps> = ({
  featureKey, open, onClose
}) => {
  const isSmall = useMediaQuery('(max-width:600px)');
  const { tier, checkAccess } = useTierAccess();
  const { config, requiredTier } = checkAccess(featureKey);

  return (
    <Dialog
      open={open}
      onClose={onClose}
      fullScreen={isSmall}
      maxWidth="sm"
      fullWidth
      PaperProps={{ sx: { maxHeight: '90vh' } }}
    >
      <DialogTitle>Upgrade Required</DialogTitle>
      <DialogContent>
        <Typography>{config?.name}</Typography>
        <Typography>Current: {tier} | Required: {requiredTier}</Typography>
        <Typography>{config?.upgradePrompt}</Typography>
      </DialogContent>
      <DialogActions>
        <Button onClick={onClose}>Maybe Later</Button>
        <Button variant="contained" onClick={onClose}>
          Upgrade (Coming Soon)
        </Button>
      </DialogActions>
    </Dialog>
  );
};

Acceptance:

  • Shows feature name, current tier, required tier
  • Displays upgrade prompt text
  • fullScreen on mobile (< 600px)
  • Upgrade button placeholder (links to close for now)
  • Matches project dialog patterns

Milestone 7: Frontend Document Form Gating

Goal: Gate scanForMaintenance checkbox in document upload.

Files:

File Action Description
frontend/src/features/documents/components/DocumentForm.tsx EDIT Gate checkbox

Implementation:

const { hasAccess } = useTierAccess();
const [upgradeDialogOpen, setUpgradeDialogOpen] = useState(false);
const canScanMaintenance = hasAccess('document.scanMaintenanceSchedule');

// Option A: Show disabled with lock icon
<FormControlLabel
  control={
    <Checkbox
      checked={canScanMaintenance ? values.scanForMaintenance : false}
      disabled={!canScanMaintenance}
      onChange={...}
    />
  }
  label={
    <Box sx={{ display: 'flex', alignItems: 'center', gap: 0.5 }}>
      Scan for Maintenance Schedule
      {!canScanMaintenance && (
        <IconButton size="small" onClick={() => setUpgradeDialogOpen(true)}>
          <LockIcon fontSize="small" />
        </IconButton>
      )}
    </Box>
  }
/>

<UpgradeRequiredDialog
  featureKey="document.scanMaintenanceSchedule"
  open={upgradeDialogOpen}
  onClose={() => setUpgradeDialogOpen(false)}
/>

Acceptance:

  • Free users see disabled checkbox with lock icon
  • Clicking lock opens UpgradeRequiredDialog
  • Pro/Enterprise users see normal checkbox
  • Works on mobile and desktop

Milestone 8: Testing and Documentation

Goal: Comprehensive test coverage and documentation.

Tests:

Test Type Coverage
feature-tiers.spec.ts Unit Tier utility functions
tier-guard.plugin.spec.ts Unit Middleware behavior
documents.service.spec.ts Integration Tier validation in documents
useTierAccess.spec.tsx Component Hook behavior
UpgradeRequiredDialog.spec.tsx Component Dialog renders correctly

Documentation Updates:

  • backend/src/config/README.md - Document feature-tiers config
  • docs/FEATURES.md - Document tier system architecture

Acceptance:

  • All tests pass
  • Test coverage for tier logic > 80%
  • Documentation updated

M8 (Testing) - runs throughout

Recommended Order: M1 -> M2 -> M3 -> M4 -> M5 -> M6 -> M7 -> M8

Risk Assessment

Risk Mitigation
Existing free users with scanForMaintenance=true Migration to set existing data to false, or grandfather existing data
Frontend/Backend tier config drift Share config via API endpoint or generate from single source
Mobile responsiveness Test on both viewports per milestone

Out of Scope (per issue requirements)

  • Stripe billing integration
  • Subscription expiration handling
  • Additional gated features beyond scanForMaintenance

Ready for review. Please provide feedback on this plan before implementation begins.

Plan Review Cycle Complete

Review Summary

Review Verdict Key Issues
QR Completeness PASS_WITH_CONCERNS Config drift strategy, missing decision log
TW Scrub NEEDS_EDITS Path errors, missing index files
QR Code PASS_WITH_CONCERNS TypeScript interface, error class, guard pattern

Blocking Issues (Must Fix Before Implementation)

1. Incorrect File Paths (TW)

Planned Path Correct Path
backend/src/config/feature-tiers.ts backend/src/core/config/feature-tiers.ts
backend/src/config/README.md backend/src/core/config/README.md

2. Missing Index Files (TW)

  • frontend/src/core/hooks/index.ts - does not exist
  • frontend/src/shared-minimal/components/index.ts - does not exist

Decision needed: Create these index files or use direct imports?

3. TypeScript Interface Update Required (QR Code)

The FastifyRequest.userContext interface at auth.plugin.ts:49-60 must be extended:

interface FastifyRequest {
  userContext?: {
    // ... existing fields
    subscriptionTier: SubscriptionTier;  // ADD THIS
  };
}

4. ForbiddenError Class Does Not Exist (QR Code)

Plan references throw new ForbiddenError({...}) but no such class exists.

Decision needed:

  • A) Create core/errors/ForbiddenError.ts
  • B) Use controller-level error response (existing pattern)

Should Fix (Before Milestone Completion)

5. Guard Pattern Inconsistency (QR Code)

requireAdmin uses direct decoration; plan shows requireTier as factory function. Should be consistent.

Recommendation: Follow requireAdmin pattern (direct decoration with parameter object).

6. Config Drift Strategy (QR Completeness)

Plan mentions risk but mitigation is vague.

Decision needed:

  • A) Backend exposes /api/config/feature-tiers endpoint
  • B) Build-time code generation
  • C) Accept manual sync (document procedure)

7. Data Migration Decision (QR Completeness)

Existing free users may have scanForMaintenance=true.

Decision needed: Grandfather existing data OR reset to false?

8. Missing Decision Log (QR Completeness)

Add section documenting:

  • Why hardcode tiers vs database-driven flags?
  • Why middleware + service validation (dual layer)?
  • Frontend/backend config sync strategy

Suggestions (Nice to Have)

  • Add explicit mobile viewport testing to M6/M7 acceptance criteria
  • Standardize terminology section (SubscriptionTier type vs subscriptionTier property)
  • Add estimated effort (S/M/L) per milestone
  • Specify test file locations (__tests__/ or alongside source)

Action Items

Before Implementation Begins:

  1. Fix file paths in plan (config/ -> core/config/)
  2. Decide: Create index files or use direct imports
  3. Decide: Create ForbiddenError class or use controller pattern
  4. Decide: Config sync strategy (API endpoint / codegen / manual)
  5. Decide: Data migration (grandfather / reset)
  6. Add decision log section to plan

Ready to start M1 after decisions are made.

Decision Log

Decisions made on blocking issues:

# Issue Decision Rationale
1 File paths Use backend/src/core/config/ Matches existing codebase structure
2 Index files Create frontend/src/core/hooks/index.ts and frontend/src/shared-minimal/components/index.ts Consistent export pattern
3 ForbiddenError class Use controller pattern (return 403 directly) Follow existing patterns, no new error class needed
4 Guard pattern requireAdmin and requireTier are distinct Different purposes: admin functions vs tier-gated paid features
5 Config sync Backend exposes /api/config/feature-tiers endpoint Frontend fetches tier config from single source of truth
6 Data migration Reset scanForMaintenance=true to false for free users Clean slate, no grandfathering

Updated Plan Amendments

M1 Update - Add API endpoint:

  • Create backend/src/core/config/feature-tiers.ts
  • Add GET /api/config/feature-tiers endpoint returning feature config

M4 Update - Controller pattern:

// In documents.controller.ts - return 403 directly
if (data.scanForMaintenance && !canAccessFeature(userTier, 'document.scanMaintenanceSchedule')) {
  return reply.code(403).send({
    error: 'TIER_REQUIRED',
    requiredTier: 'pro',
    currentTier: userTier,
    feature: 'document.scanMaintenanceSchedule',
    upgradePrompt: '...'
  });
}

M5 Update - Fetch from API:

// useTierAccess fetches config from backend
const configQuery = useQuery({
  queryKey: ['featureTiers'],
  queryFn: () => api.get('/api/config/feature-tiers'),
  staleTime: 30 * 60 * 1000, // 30 min - config rarely changes
});

New: Data Migration (add to M4):

-- Migration: Reset scanForMaintenance for free users
UPDATE documents d
SET scan_for_maintenance = false
FROM user_profiles u
WHERE d.user_id = u.auth0_sub
  AND u.subscription_tier = 'free'
  AND d.scan_for_maintenance = true;

All blocking issues resolved. Ready to begin implementation.

Files Modified

File Change
backend/src/features/documents/api/documents.controller.ts Added tier validation for scanForMaintenance on create/update

Implementation Summary

Controller Tier Validation (lines 88-106, 134-153):

// Tier validation: scanForMaintenance requires Pro tier
const featureKey = 'document.scanMaintenanceSchedule';
if (request.body.scanForMaintenance && !canAccessFeature(userTier, featureKey)) {
  const config = getFeatureConfig(featureKey);
  return reply.code(403).send({
    error: 'TIER_REQUIRED',
    requiredTier: config?.minTier || 'pro',

    feature: featureKey,
    featureName: config?.name || null,
    upgradePrompt: config?.upgradePrompt || '...',
  });
}

Data Migration:

-- Reset scanForMaintenance for free tier users
UPDATE documents d
SET scan_for_maintenance = false
FROM user_profiles u
WHERE d.user_id = u.auth0_sub
  AND u.subscription_tier = 'free'
  AND d.scan_for_maintenance = true;

Test Results

PASS documents.controller.tier.test.ts (8 tests)
  - allows free user to create document without scanForMaintenance
  - blocks free user from using scanForMaintenance=true
  - allows pro user to use scanForMaintenance=true
  - allows enterprise user to use scanForMaintenance=true
  - defaults to free tier when userContext is missing
  - allows free user to update document without scanForMaintenance
  - blocks free user from setting scanForMaintenance=true on update
  - allows pro user to set scanForMaintenance=true on update

Milestone 5 Complete: Frontend Tier Access Hook

Files Created

File Description
frontend/src/core/hooks/useTierAccess.ts React hook for tier-based feature access checking
frontend/src/core/hooks/index.ts Barrel export for core hooks

Files Modified

File Change
frontend/src/features/settings/types/profile.types.ts Added SubscriptionTier type and subscriptionTier field to UserProfile

Hook API

import { useTierAccess } from '@/core/hooks';

const MyComponent = () => {
  const { tier, loading, hasAccess, checkAccess } = useTierAccess();

  // Simple boolean check
  if (!hasAccess('document.scanMaintenanceSchedule')) {
    // Show upgrade prompt
  }

  // Detailed access info
  const access = checkAccess('document.scanMaintenanceSchedule');
  // { allowed: false, requiredTier: 'pro', config: { name: '...', upgradePrompt: '...' } }
};

Implementation Details

  1. Profile Query: Uses existing user-profile query key with 5-minute stale time
  2. Feature Config Query: Fetches from /api/config/feature-tiers with 30-minute stale time
  3. Tier Comparison: Uses numeric levels (free=0, pro=1, enterprise=2)
  4. Fail Open: Unknown features return allowed: true for safety

Type Check

tsc --noEmit: PASS

Acceptance Criteria

  • Hook returns current tier
  • hasAccess(featureKey) returns boolean
  • checkAccess(featureKey) returns full access info
  • Uses React Query with appropriate caching
  • Type definitions updated for SubscriptionTier

Milestone 7 Complete: Frontend Document Form Gating

Files Modified

File Change
frontend/src/features/documents/components/DocumentForm.tsx Added tier gating for scanForMaintenance checkbox

Implementation Details

Imports added:

import { UpgradeRequiredDialog } from '../../../shared-minimal/components/UpgradeRequiredDialog';
import LockOutlinedIcon from '@mui/icons-material/LockOutlined';
import { useTierAccess } from '../../../core/hooks/useTierAccess';

Hook usage:

const { hasAccess } = useTierAccess();
const canScanMaintenance = hasAccess('document.scanMaintenanceSchedule');
const [upgradeDialogOpen, setUpgradeDialogOpen] = React.useState(false);

UI Behavior:

  • Free users: Checkbox is disabled and grayed out, with a lock icon next to it
  • Clicking lock icon: Opens UpgradeRequiredDialog
  • Pro/Enterprise users: Normal checkbox with "(Coming soon)" text

Visual Comparison

Free User:

[ ] Scan for Maintenance Schedule [Lock Icon]
     (disabled, grayed out)

Pro/Enterprise User:

[x] Scan for Maintenance Schedule (Coming soon)
     (enabled, functional)

Type Check

tsc --noEmit: PASS

Acceptance Criteria

  • Free users see disabled checkbox with lock icon
  • Clicking lock opens UpgradeRequiredDialog
  • Pro/Enterprise users see normal checkbox
  • Works on mobile and desktop (responsive form)
