"""
Seed a fresh dev database with a usable set of users.

Pre-prod data is fake; after the JSONB→relational cutover the schema is built from
the SQLAlchemy models on startup (Base.metadata.create_all). This script inserts a
handful of approved users so the app is exercisable without going through Supabase
sign-up for every role.

NOTE: these users have RANDOM uuids (not real Supabase identities). They're for
backend smoke tests / local poking. Real users are provisioned just-in-time on
their first authenticated request (auth.py), keyed on their Supabase auth.uid().

Usage (from backend/, with env loaded):
    python scripts/seed_dev.py
    python scripts/seed_dev.py --wipe    # delete existing seed rows first
