- Create the admin, a Default project and its API keys through upstream's LANGFUSE_INIT_* variables on first start, save them to ~/langfuse.creds, then drop the one-time values from .env and keep sign-up disabled. - Update SeaweedFS and golang-migrate from their own releases. - Let langfuse-migrate want, not require, the local PostgreSQL, ClickHouse, Redis and SeaweedFS units, so an external server can replace one. - Explain the build-time DOCKER_BUILD flag and drop it from the runtime .env.
- Read var_admin_pass (declared in app_vars, exported from the ct script) and use it for the first-start admin account. - Generate a password when it is empty, or when it is shorter than Langfuse's 8-character minimum or holds spaces, quotes or backslashes that systemd's EnvironmentFile parser would alter.

/opt/langfuse_data/.envand survives updates.var_admin_email, defaultadmin@example.com;var_admin_pass, generated when empty), a Default project and its API keys through upstream'sLANGFUSE_INIT_*variables. The login and keys go to~/langfuse.creds, the one-time values are then removed from.env, and sign-up stays disabled.Wants=the local PostgreSQL, ClickHouse, Redis and SeaweedFS units, so any of them can be disabled in favour of an external server configured in.env.🔗 Related PR / Issue
