February 2026 Implementation Summary

Complete Multi-Tenant SaaS Transformation

Implementation Period: February 1-19, 2026 Status: COMPLETE — UX flow fixes implemented on Feb 19 Total Changes: 115+ files modified/created E2E Tests: 47 comprehensive security tests Multi-Tenant Testing: Full flow verified (see MULTI_TENANT_TESTING_REPORT.md)

📋 Executive Summary

Successfully transformed the LMS from a single-tenant application into a production-ready multi-tenant SaaS platform with comprehensive revenue management, security testing, payment infrastructure, and context-aware UX routing.

Key Achievements

  1. ✅ Multi-Tenant Architecture - Full tenant isolation across 65+ tables
  2. ✅ Revenue Model - Stripe Connect with 80/20 revenue splits
  3. ✅ Multi-Payment Support - Stripe + Manual/Offline payments
  4. ✅ E2E Security Testing - 47 comprehensive tests
  5. ✅ Join School Flow - Multi-school membership
  6. ✅ Plan Limits Enforcement - Free (5), Basic (20), Pro (100), Enterprise (unlimited)
  7. ✅ Onboarding Wizard - Payment setup integration
  8. ✅ Tenant-Scoped Gamification - XP/levels/streaks/achievements/store/leaderboard isolated per school with plan-gated premium upsell
  9. ✅ Comprehensive Documentation - 15+ guides
  10. ✅ Context-Aware UX Routing - School vs platform landing pages, smart signup redirect (Feb 19)

🎯 Feb 19 — UX Flow Fixes: Context-Aware Routing & School Landing Pages

Addressed three distinct product problems where the platform treated school owners and students identically:

Problem

  • Main domain signup → /dashboard/student with no school attached → confused user, wasted acquisition
  • School subdomain (myschool.platform.com) showed generic platform marketing → embarrassed school owners sharing the link with students
  • Post-signup email confirmation → / regardless of context → users stranded with no clear next step

Fix 1 — Context-Aware Navbar (components/public/navbar.tsx)

Added isMainPlatform detection (tenant.id === DEFAULT_TENANT_ID) to branch both nav links and CTAs:

Context Nav Links CTA
Main domain Features · Pricing · For Creators "Start Free →" → /create-school
School subdomain Courses · About "Join [School Name]" → /auth/sign-up?next=/join-school

Fix 2 — School Landing Page

components/public/school-landing-page.tsx (new server component):

  • Section 1: School logo/initial circle, school name, join + login CTAs — all styled with tenant.primary_color
  • Section 2: Published courses grid (thumbnail, name, price badge, "View →" link) with empty-state fallback
  • Section 3: Join CTA strip with school name

app/[locale]/(public)/page.tsx — early-return at top:

  • Detects tenantId !== DEFAULT_TENANT_ID
  • Fetches published products for that tenant
  • Returns <SchoolLandingPage> — entire platform marketing page below is untouched

Fix 3 — Smart After-Signup Redirect (app/[locale]/auth/confirm/route.ts)

For type=signup, checks tenant_users memberships before redirecting:

Has active memberships? → /dashboard/student    (returning user)
No memberships + main domain → /create-school  (new creator)
No memberships + school subdomain → /join-school (new student)

All other OTP types (recovery etc.) continue using the next param.

Files Changed (Feb 19)

File Type
components/public/navbar.tsx Edit — isMainPlatform conditional CTAs/links
app/[locale]/(public)/page.tsx Edit — tenant detection + early-return
components/public/school-landing-page.tsx New — school hero + courses grid + join strip
app/[locale]/auth/confirm/route.ts Edit — smart signup redirect
messages/en.json, messages/es.json Edit — added features, pricing, startFree, join navbar keys

No DB migrations. No new routes. No middleware changes.

🔧 Phase 1: Multi-Tenant Foundation (Feb 1-5)

Database Changes

New Tables:

  • tenants - School/organization records
  • tenant_users - Many-to-many user-tenant relationships
  • tenant_settings - Per-tenant configuration
  • super_admins - Platform administrators

Schema Updates:

  • Added tenant_id UUID NOT NULL to 65+ existing tables
  • Created DEFAULT auth.tenant_id() function
  • Default tenant ID: 00000000-0000-0000-0000-000000000001

Global Tables (No tenant_id):

  • profiles - Users can belong to multiple tenants
  • gamification_levels - Global level definitions
  • gamification_achievements - Global definitions (optional tenant_id for school-specific)
  • gamification_store_items - Global definitions (optional tenant_id for school-specific)

Migrations Created:

├── 20260201000000_create_multi_tenancy_infrastructure.sql
├── 20260202000000_add_tenant_id_to_all_tables.sql
└── 20260203000000_backfill_tenant_id_data.sql

JWT Enhancement

Updated custom_access_token_hook():

-- Added JWT claims:
{
  "tenant_id": "uuid",
  "tenant_role": "student|teacher|admin",
  "is_super_admin": boolean
}

Helper Functions:

  • auth.tenant_id() - Get current user's tenant from JWT
  • auth.tenant_role() - Get user's role in current tenant
  • auth.is_super_admin() - Check super admin status

RLS Policy Pattern

Standard Pattern Applied:

-- Read policy
CREATE POLICY "Tenant isolation - select"
ON table_name FOR SELECT
USING (tenant_id = auth.tenant_id() OR auth.is_super_admin());

-- Write policies
CREATE POLICY "Tenant isolation - insert"
ON table_name FOR INSERT
WITH CHECK (tenant_id = auth.tenant_id());

📊 Phase 2: Tenant Filtering Implementation (Feb 6-8)

Files Modified: 50+

Query Pattern Applied:

// BEFORE (INSECURE)
const { data } = await supabase
  .from('courses')
  .select('*')

// AFTER (SECURE)
const tenantId = await getCurrentTenantId()
const { data } = await supabase
  .from('courses')
  .select('*')
  .eq('tenant_id', tenantId)

🔐 Phase 3: Authentication & Tenant Context (Feb 9-10)

Login Flow Enhancement

Files Modified:

  • app/[locale]/auth/login/page.tsx - Passes tenant context
  • components/login-form.tsx - Accepts tenantId prop

Implementation:

// Login page passes tenant
const tenantId = await getCurrentTenantId()
return <LoginForm tenantId={tenantId} />

// Login form uses tenant
await supabase.auth.signInWithPassword({
  email,
  password,
  options: {
    data: { tenant_id: tenantId }
  }
})

Password Reset Fix

File: components/forgot-password-form.tsx

Fix: Preserve subdomain in redirectTo:

const currentHost = window.location.host
const protocol = window.location.protocol

await supabase.auth.resetPasswordForEmail(email, {
  redirectTo: `${protocol}//${currentHost}/auth/update-password`
})

Email Confirmation Fix

File: app/[locale]/auth/confirm/route.ts

Fix: Set preferred_tenant_id after confirmation:

const tenantId = await getCurrentTenantId()
const { data: { user } } = await supabase.auth.getUser()

if (user) {
  await supabase.auth.updateUser({
    data: { preferred_tenant_id: tenantId }
  })
}

Tenant Switcher Enhancement

File: components/tenant/tenant-switcher.tsx

Fix: Refresh JWT after switch:

await supabase.auth.updateUser({
  data: { preferred_tenant_id: tenantId }
})

// CRITICAL: Refresh session to get new JWT claims
await supabase.auth.refreshSession()

// Navigate to new subdomain
window.location.href = `https://${tenant.slug}.${platformDomain}/dashboard`

Middleware Enhancement

File: proxy.ts

Features Added:

  • Subdomain extraction from host header
  • Tenant ID resolution from slug
  • Auto-redirect to /join-school for non-members
  • JWT header injection for tenant context
// Extract subdomain
const host = request.headers.get('host')
const subdomain = host?.split('.')[0]

// Resolve tenant
const { data: tenant } = await supabase
  .from('tenants')
  .select('id')
  .eq('slug', subdomain)
  .single()

// Check membership
if (tenant && user) {
  const { data: membership } = await supabase
    .from('tenant_users')
    .select('id')
    .eq('user_id', user.id)
    .eq('tenant_id', tenant.id)
    .eq('status', 'active')
    .single()

  if (!membership && !request.nextUrl.pathname.startsWith('/join-school')) {
    return NextResponse.redirect(new URL('/join-school', request.url))
  }
}

if (!tenant?.stripe_account_id) {
  return new Response('School has not connected payment account', { status: 400 })
}

// Get revenue split
const { data: split } = await supabase
  .from('revenue_splits')
  .select('platform_percentage')
  .eq('tenant_id', tenantId)
  .single()

const platformFee = Math.round((amount * (split?.platform_percentage || 20)) / 100)

// Create payment intent
const paymentIntent = await stripe.paymentIntents.create({
  amount,
  currency: 'usd',
  application_fee_amount: platformFee,
  transfer_data: {
    destination: tenant.stripe_account_id
  },
  metadata: {
    transactionId,
    userId,
    tenantId
  }
})

Webhook Enhancements

    .from('transactions')
    .select('*')
    .eq('stripe_payment_intent_id', paymentIntent)
    .single()

  if (transaction) {
    // Mark as refunded
    await supabaseAdmin
      .from('transactions')
      .update({ status: 'refunded' })
      .eq('transaction_id', transaction.transaction_id)

    // Cancel enrollments

        .update({ subscription_status: 'canceled' })
        .eq('user_id', transaction.user_id)
        .eq('plan_id', transaction.plan_id)
    }
  }
  break
}

🎯 Phase 8: Plan Limits Enforcement (Feb 15)

Implementation

File: app/actions/teacher/courses.ts

Plan Limits:

const PLAN_LIMITS = {
  free: 5,
  basic: 20,
  professional: 100,
  enterprise: Infinity
} as const

export async function checkCourseLimit() {
  const tenantId = await getCurrentTenantId()
  const supabase = await createClient()

  // Get tenant's plan
  const { data: tenant } = await supabase
    .from('tenants')
    .select('plan')
    .eq('id', tenantId)
    .single()

  const plan = tenant?.plan || 'free'
  const limit = PLAN_LIMITS[plan as keyof typeof PLAN_LIMITS] || 5

  // Count existing courses
  const { count } = await supabase
    .from('courses')
    .select('*', { count: 'exact', head: true })
    .eq('tenant_id', tenantId)

  return {
    currentCount: count || 0,
    limit,
    canCreate: (count || 0) < limit,
    plan
  }
}

export async function createCourse(courseData: CourseFormData) {
  const { canCreate, limit, plan } = await checkCourseLimit()

  if (!canCreate) {
    throw new Error(
      `Your ${plan} plan is limited to ${limit} courses. Upgrade to create more.`
    )
  }

  // Create course...
}

UI Integration:

// Show limit in UI
const { currentCount, limit, plan } = await checkCourseLimit()

return (
  <div>
    <p>Courses: {currentCount} / {limit === Infinity ? '∞' : limit}</p>
    {limit !== Infinity && currentCount >= limit && (
      <Alert>
        <p>Course limit reached. Upgrade your plan to create more.</p>
        <Button href="/pricing">Upgrade Plan</Button>
      </Alert>
    )}
  </div>

Phase 8: Multi-Tenant E2E Testing (Feb 17)

What Was Tested

Full end-to-end verification of the multi-tenant SaaS architecture using lvh.me wildcard DNS for local subdomain testing.

Tenants tested:

  • Default School (lvh.me:3000) — platform root
  • Code Academy Pro (code-academy.lvh.me:3000) — created during testing

Flows verified:

  1. School creation via create_school RPC
  2. Subdomain → tenant resolution in proxy.ts
  3. Role resolution from tenant_users (authoritative, not JWT)
  4. Course creation scoped to tenant
  5. Product and plan creation per tenant
  6. Student sign-up and join-school flow
  7. Manual payment request and enrollment
  8. Cross-tenant data isolation (courses, enrollments, products)

Bugs Found & Fixed (8)

Bug Fix
proxy.ts port comparison failed with lvh.me:3000 Strip port from PLATFORM_DOMAIN at module level
Proxy used stale JWT role for routing Read role from tenant_users table
getUserRole() returned wrong role cross-tenant Check tenant_users first, fall back to JWT
create-school-form.tsx hardcoded https:// Use window.location.protocol
enroll_user() RPC set null status Set status = 'active' and inherit tenant_id
No INSERT RLS on tenant_users Added policy for student self-join
Missing handle_new_user trigger Created trigger to auto-create profiles
No DELETE RLS on lesson_completions Added DELETE policy for uncomplete flow

Known Remaining Issues

  • i18n keys render raw on course detail page
  • Admin dashboard shows cross-tenant aggregate stats
  • Sidebar shows "LMS Platform" instead of tenant name
  • Admin page has Next.js 16 async params error

Full Report

See MULTI_TENANT_TESTING_REPORT.md for detailed test results with step-by-step verification.

Phase 9: Tenant-Scoped Gamification with Premium Upsell (Feb 17)

Problem

The gamification system (XP, levels, achievements, store, leaderboard, streaks) worked but was globally scoped — all 10 gamification tables lacked tenant_id. Students from different schools shared the same XP pool, leaderboard, and achievements. This was the single largest multi-tenant isolation gap.

Solution

Migration: 20260217030000_tenant_scope_gamification.sql

  1. Added tenant_id NOT NULL to 7 data tables (nullable-first strategy: add nullable, backfill with default tenant, set NOT NULL)
  2. Added optional tenant_id to 2 definition tables (gamification_achievements, gamification_store_items) for school-specific customization
  3. Updated all unique constraints to composite keys: (user_id, tenant_id)
  4. Rewrote all RLS policies to use get_tenant_id()
  5. Rewrote award_xp() with _tenant_id parameter and UPSERT for lazy profile creation
  6. Rewrote all 5 XP trigger functions to resolve tenant_id from source tables
  7. Rewrote refresh_leaderboard_cache() with PARTITION BY tenant_id
  8. Created get_gamification_features() RPC for plan-based feature gating

Edge Functions Updated (4):

  • get-gamification-summary — tenant filter + features in response
  • get-leaderboard — tenant filter + 403 on locked plan
  • check-achievements — tenant filter + plan check
  • spend-points — tenant filter + plan check + bug fixes (is_active → is_available, item.title → item.name)

Frontend Updated (6 files):

  • use-gamification.ts — Added GamificationFeatures interface
  • gamification-header-card.tsx — Conditional trophy icon
  • mini-leaderboard.tsx — Upgrade prompt for free plan
  • achievement-grid.tsx — Upgrade prompt
  • store-section.tsx — Upgrade prompt
  • i18n keys added in both en.json and es.json

Plan-Gated Feature Matrix

Plan XP/Levels/Streaks Leaderboard Achievements Store
free Yes Locked Locked Locked
basic Yes Yes Yes Locked
professional Yes Yes Yes Yes
enterprise Yes Yes Yes Yes

Verified via Playwright MCP

  • Tenant isolation: Same user has separate XP profiles per tenant (310 XP in Default School vs 25 XP in test-academy)
  • Plan gating: All 3 tiers tested — features correctly lock/unlock on plan change
  • Dynamic switching: Changing plan in DB immediately reflects in UI on page reload

Phase 10: Full Monetization Stack (Feb 18)

Overview

Implemented the complete business monetization system: school billing, 5-tier pricing, feature gating, LATAM payment support, revenue dashboard, and upgrade nudges. This transforms the LMS from a free product into a revenue-generating SaaS.

New Database Tables

Table Purpose
platform_plans 5-tier plan definitions with features JSONB, limits JSONB, Stripe price IDs
platform_subscriptions Per-tenant billing (Stripe or manual transfer). UNIQUE(tenant_id)
platform_payment_requests Manual bank transfer requests for plan upgrades

Altered tenants table: Added stripe_customer_id, billing_email, billing_period_end, billing_status

Altered currency_type enum: Added mxn, cop, clp, pen, ars, brl

New RPC: get_plan_features(_tenant_id) — single source of truth for plan features/limits

Pricing Tiers (Seeded)

Plan $/mo Courses Students Transaction Fee
Free $0 5 50 10%
Starter $9 15 200 5%
Pro $29 100 1,000 2%
Business $79 Unlimited 5,000 0%
Enterprise $199 Unlimited Unlimited 0%

Two Separate Stripe Integrations

  • School billing (NEW): Stripe Checkout + Subscriptions at /api/stripe/checkout-session, /api/stripe/billing-portal, /api/stripe/platform-webhook
  • Student payments (EXISTING): Stripe Connect at /api/stripe/create-payment-intent, /api/stripe/webhook
