+"""initial_baseline - Use 000_initial_schema.sql for fresh deployments
+
+Revision ID: 001_initial_baseline
+Revises:
+Create Date: 2026-01-02 16:45:00.000000
+
+IMPORTANT: This is a baseline migration for existing databases.
+
+For FRESH deployments:
+1. Run: psql -U user -d dbname -f backend/migrations/000_initial_schema.sql
+2. Run: alembic stamp head
+
+For EXISTING deployments (already have database):
+1. Run: alembic stamp head  (marks database as up-to-date)
+
+This migration intentionally does NOTHING because:
+- Fresh deployments use 000_initial_schema.sql to create all tables
+- Existing deployments already have all tables from 000_initial_schema.sql
+- Future migrations will be incremental changes from this baseline
