Phase 01 Plan 02: Database Schema Summary

Multi-tenant auth schema with plans table, profiles table, RLS policies, and auto-profile trigger for Supabase

Performance

• Duration: 5 min
• Started: 2026-01-31T03:24:00Z
• Completed: 2026-01-31T03:29:00Z
• Tasks: 3
• Files created: 3

Accomplishments

• Created plans table with Free, Creator, Pro tiers (0, 19, 49 EUR/month)
• Created profiles table with tenant_id for multi-tenant isolation
• Enabled RLS on all tables with optimized policies
• Added auto-profile creation trigger on user signup
• Added helper functions for plan limit checking
• Documented complete schema with security notes

Task Commits

Each task was committed atomically:

1. Task 1: Create database migration with plans and profiles - f271d7f (feat)
2. Task 2: Create seed file for development - 16b3053 (feat)
3. Task 3: Document database schema - fd56b12 (docs)

Files Created

• supabase/migrations/001_initial_auth_setup.sql - Complete auth schema with RLS
• supabase/seed.sql - Development verification seed
• docs/DATABASE.md - Schema documentation with examples

Decisions Made

1. tenant_id in profiles, not JWT - Simpler approach for v1, avoids JWT refresh complexity
2. Plans in migration, not seed - Plans must always exist, migration guarantees this
3. JSONB for features - Flexible structure for plan limits, easy to extend
4. Italian display names - i18n ready from day 1

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

User Setup Required

Database migration must be applied to Supabase. See docs/DATABASE.md for:

• SQL Editor copy/paste method
• Supabase CLI method
• Direct psql connection method

Next Phase Readiness

• Schema ready for Supabase project creation (01-03)
• Plans table ready for auth flow (01-04)
• Profiles auto-creation ready for signup testing
• RLS policies ready for security verification
