docs/DATABASE.md

tenant_id in profiles table, not JWT (simpler for v1)

Plans seeded in migration, not seed file (always exist)

JSONB features for flexible plan limits

Italian display names for i18n readiness

RLS Policy Pattern: Use (SELECT auth.uid()) for 99% performance improvement

Auto-profile Pattern: Trigger creates profile on auth.users insert

Helper Function Pattern: SECURITY DEFINER for cross-table queries

Task Commits

Each task was committed atomically:

Task 1: Create database migration with plans and profiles - f271d7f (feat)
Task 2: Create seed file for development - 16b3053 (feat)
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

tenant_id in profiles, not JWT - Simpler approach for v1, avoids JWT refresh complexity
Plans in migration, not seed - Plans must always exist, migration guarantees this
JSONB for features - Flexible structure for plan limits, easy to extend
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

Phase: 01-foundation-auth Completed: 2026-01-31
