+     *
+     * Canonical example:
+     *   1) User requests an operation, such as face enrollment.
+     *   2) Face enrollment cannot happen until the user confirms their lockscreen credential
+     *      (PIN/Pattern/Password).

+     *      confirmation. It needs proof that the user explicitly authenticated credential in order
+     *      to allow addition of biometric enrollments.
+     * To secure this path, the following path is taken:
+     *   1) Upon user requesting face enroll, the framework requests
+     *      IFace#generateChallenge
+     *   2) Framework sends the challenge to the credential subsystem, and upon credential
+     *      confirmation, a HAT is created, containing the challenge in the "challenge" field.
+     *   3) Framework sends the HAT to the HAL, e.g. ISession#enroll.
+     *   4) Implementation verifies the authenticity and integrity of the HAT.
+     *   5) Implementation now has confidence that the user entered their credential to allow
+     *      biometric enrollment.
+     *
+     * Note that the interface allows multiple in-flight challenges. For example, invoking
+     * generateChallenge(0, 0, timeoutSec) twice does not invalidate the first challenge. The
+     * challenge is invalidated only when:
+     *   1) The provided timeout expires, or
+     *   2) IFace#revokeChallenge is invoked
