+# 0002 Freelancer OS Core Tables
+
+SQL file: `supabase/migrations/0002_add_freelancer_os_core_tables.sql`
+
+## Purpose
+
+Adds the database model required for the Freelancer OS MVP.
+
+This migration keeps the existing baseline from `supabase/schema.sql` and extends it instead of replacing it. The existing `tasks` table is reused and enriched with freelancer-specific fields.
+
+## What It Creates
+
+- `clients`
+- `projects`
+- `calendar_events`
+- `finance_transactions`
+- `daily_logs`
+- `app_settings`
+- `set_updated_at()` trigger function
+- updated-at triggers for the new tables
+- indexes for common dashboard/report queries
+- RLS policies for every new table
+
+## What It Changes
+
+The existing `tasks` table gets these additional columns:
+
+- `client_id`
+- `project_id`
+- `priority`
+- `due_at`
+- `estimated_minutes`
+- `actual_minutes`
+
+This lets a task belong to a client and/or project while preserving the earlier journal/task prototype schema.
+
+## MVP Coverage
+
+This migration supports:
+
+- client management
+- client projects
+- side projects
+- task planning
+- calendar planning
+- income and expense tracking
+- daily mood/energy logging
+- app and AI provider settings
+
+## RLS Model
+
+Every new table has `user_id`.
+
+Policies follow the same pattern:
+
+- users can select their own rows
+- users can insert rows only for themselves
+- users can update their own rows
+- users can delete their own rows
+
+## Notes
+
+`app_settings.api_key` exists for compatibility with the current prototype flow. For production-grade use, provider credentials should be encrypted or moved to a safer secret-management strategy.
+
+`daily_logs` is the new MVP-oriented replacement for the earlier `journals` concept. The old `journals` table remains available until the UI migration is complete.
+
+## Execution
+
+Run this after `supabase/schema.sql`.
+
+Do not add this file to `query-log.md` until it has actually been executed against a database.
