+ * Notes from probing the runtime:
+ *  - A missing pool is `ResourceNotFoundException` and a missing user is
+ *    `UserNotFoundException`, both with HTTP **400**; `get` matches on the name.
+ *  - With email sign-in the stored `Username` is the generated `sub`, not the
+ *    address, so users are keyed by `Username` and the email is read from the
+ *    attributes. Admin calls accept either form.
+ *  - An omitted password policy defaults to requiring upper, lower, number and
+ *    symbol, matching AWS.
+ *  - `InitiateAuth` with `USER_PASSWORD_AUTH` issues real tokens once a user's
+ *    password is permanent, so users created here can sign in immediately.
+ *  - `EstimatedNumberOfUsers` stays 0 however many users exist (AWS also only
+ *    updates it periodically), so `userCount` is counted with `ListUsers`.
+ *  - An admin action the user's state does not allow (confirming a confirmed
+ *    user) is `NotAuthorizedException`, surfaced here as a conflict because the
+ *    console caller is authorised and a 401 would end the console session.
+ *
+ * Users are the pool's child items. The app client is created with the pool, as
+ * the console's create flow does, and its id is surfaced in the pool metadata.
