    /**
     * Will record ("mark") that a user has "seen" an experiment condition per at the Assignment's decision point location (site + target).
     *
     * Marking the decision point will record the user's condition assignment and the time of the decision point, regardless of whether the user is enrolled in an experiment.
     *
     * @param status `status` signifies a client application's note on what it did in the code with condition assignment that Upgrade provided.
     *  Status can be one of the following:
     *
     * ```ts
     * export enum MARKED_DECISION_POINT_STATUS {
     *   CONDITION_APPLIED = 'condition applied',
     *   CONDITION_FAILED_TO_APPLY = 'condition not applied',
     *   NO_CONDITION_ASSIGNED = 'no condition assigned',
     * }
     * ```
     * @param uniquifier A `uniquifier` unique string can be sent along to help tie a user's logged metrics to a specific marked condition.
     * This identifier will also need to be sent when calling `upgradeClient.log()`
     * This is required for 'within-subjects' experiments.
     *
     * @param clientError The client can also send along an additional `clientError` string to log context as to why a condition was not applied.
     *
     * @example
     * ```ts
     * import { MARKED_DECISION_POINT_STATUS } from 'upgrade_types';
     *
     * const site = 'dashboard';
     * const target = 'experimental button';
     * const status: MARKED_DECISION_POINT_STATUS = MARKED_DECISION_POINT_STATUS.CONDITION_FAILED_TO_APPLY
     * const clientError = 'variant not recognized'; //optional
     *
     *  ```ts
     * const assignment: Assignment[] = await upgradeClient.getDecisionPointAssignment(site, target);
     * const markResponse = await assignment.markDecisionPoint(MARKED_DECISION_POINT_STATUS.CONDITION_APPLIED);
     * ```
     *
     * Note*: mark can also be called via `Client.markDecisionPoint()` without an Assignment object`:
     * ```ts
     * import { MARKED_DECISION_POINT_STATUS } from 'upgrade_types';
     *
     * const site = 'dashboard';
     * const target = 'experimental button';
     * const condition = 'variant_x'; // send null if no condition / no experiment is running / error
     * const status: MARKED_DECISION_POINT_STATUS = MARKED_DECISION_POINT_STATUS.CONDITION_FAILED_TO_APPLY
     * const clientError = 'variant not recognized'; //optional
     *
     * const markResponse = await upgradeClient.markDecisionPoint(site, target, condition, MARKED_DECISION_POINT_STATUS.CONDITION_APPLIED);
     * ```
