# setup-dev-user.sh — Create a local-dev user account end-to-end.
#
# Calls mana-auth's POST /api/v1/auth/register (which goes through
# Better Auth's signUpEmail), then runs an idempotent SQL UPDATE to
# mark the email as verified and lift the access tier to 'founder'
# so the new user can immediately exercise every tier-gated module.
#
# Why both steps?
#   - Better Auth's createUser hashes the password the way the runtime
#     expects (scrypt). Hand-rolling INSERTs in raw SQL would either
#     hash wrong (login fails) or pull a moving-target dependency.
#   - The local mana-auth has `requireEmailVerification: true` and no
#     real SMTP wired up. The verification token sits in
#     `auth.verification` waiting for someone to click it. The SQL
#     bypass at the end is the standard local-dev shortcut.
#   - The default tier is `public`. Founder is the highest tier so
#     every requiredTier check passes — that's the point of a dev
#     account.
#
# Usage:
#   ./scripts/dev/setup-dev-user.sh                  # creates the 3 default accounts
#   ./scripts/dev/setup-dev-user.sh email@x.de pass  # creates a single account
#
# Defaults are tills95@gmail.com, tilljkb@gmail.com, rajiehq@gmail.com
# all with password "Aa-123456789".
#
# Idempotent: existing users get tier/email_verified re-applied without
# touching their password. Re-running the script after a partial setup
# is safe.
#
# Prereqs:
#   - Postgres up + reachable at localhost:5432 (`pnpm docker:up`)
#   - mana-auth running on :3001 (`pnpm dev:auth`)
#   - psql in PATH
