From 1215356990cd5574b0f35c5fff88fefe47a4fa3e Mon Sep 17 00:00:00 2001 From: chahinebrini Date: Sat, 16 May 2026 02:38:59 +0200 Subject: [PATCH] feat(backend): add POST /api/devices/check-lock for native auth flow Native app uses supabase.auth.signInWithPassword directly, bypassing /api/auth/login. This authenticated endpoint runs the same device-lock check post-auth: 409 DEVICE_LOCKED if bound to another user, 200+bind if Pro/Legend user, no-op bind for Free users. CORS headers extended to include x-device-name/model/os. 34 tests green.
