> ## Agent Instructions
> These are the DualMind developer and admin docs. The API base URL is https://api.dualmindlab.tech and the local API runs on http://localhost:5079.
> Never send POST, PUT, PATCH or DELETE requests to the production API while developing; use a local API and a development Supabase project.
> Environment variables are documented by name only. Never ask for or print secret values.
> Admin routes under /api/admin require a Supabase access token for a user whose public.users.role is admin. The PUT routes for users, models, providers and threads write every field, so send the full record; PUT /api/admin/keys/{keyId} writes only the fields you send (sending api_key replaces the key).

# Update a user

> Replaces the editable fields.

**Send the full record.** This handler writes every field of the request DTO, so a field you leave out is saved as `null`. Read the record first and send all fields back with your changes.

    (the `AdminOnly` policy). Responses use the `{ success, data, total, page,
    pageSize, message, error }` envelope.
