MobileAppQRLogin::shuffled_candidate_numbers │ private │ WC 1.0

Build the shuffled candidate triple returned by /qr-login-status while in the scanned state. The order is fixed at scan time (in scan_token) and stored in challenge.shuffled so every poll returns the same array — re-shuffling per-poll caused visible tile flicker on wc-admin. Falls back to building + shuffling on the fly for any token record that predates the persisted-shuffle change.

Method of the class: MobileAppQRLogin{}

No Hooks.

Returns

array<int, string>.

Usage

// private - for code of main (parent) class only
$result = $this->shuffled_candidate_numbers( $challenge ): array;
$challenge(array<string, mixed>) (required)
The challenge payload from the token record.
