// ST-1003: POST /api/auth/pair/start — anonieme endpoint die een nieuwe
|
|
// LoginPairing aanmaakt voor de QR-pairing-flow (M10).
|
|
//
|
|
// Genereert twee gescheiden 256-bit geheimen:
|
|
// - mobileSecret → komt in JSON-body terug zodat de desktop het in een
|
|
// QR-fragment kan plaatsen (wordt nooit naar onze server gestuurd)
|
|
// - desktopToken → wordt als HttpOnly cookie gezet zodat alleen deze
|
|
// browser de SSE-stream en claim mag uitvoeren
|
|
//
|
|
// Rate-limit: 10 pogingen per IP per minuut (lib/rate-limit.ts → 'pair-start').
