Backup / restore flow: - deviceBackup.ts: v2 format wrapping userId + deviceId + privateKey in an encrypted JSON payload so restore can re-seed localStorage, vault, and reattach to the existing server-side device row without provisioning a new one (conv-key bundles stay valid, no "awaiting key" state) - shared/auth: restoreDeviceFromServerRecord — verifies session.user.id matches the backup's userId, confirms the server device row still exists, then writes the private key into the local secret store - BackupExportDialog — passphrase + confirm, generates portable string, copy + download .txt - DeviceRestore — textarea + passphrase → seeds vault + writes deviceId cache, treats this install as the original device - DevicePage now has tabs "Neu einrichten" / "Backup wiederherstellen" - BackupPromptBanner — post-registration nudge, reads sessionStorage signal from fresh provisions and persists "never-ask-again" in localStorage so it stops nagging - SettingsPage backup section: uses the new dialog; removes the dangerous in-place key import (restore now lives in the device flow) Username casing: - Migration 20260420000002 drops lower() from the handle_new_user trigger and widens the regex to [A-Za-z0-9_]. profiles.username is citext so uniqueness + lookups stay case-insensitive regardless of stored casing - Shared auth: trim() only, no toLowerCase on signup/lookups/search. ilike handles CI anyway and citext makes client normalisation redundant - AuthPage regex + input preserve case, FriendsPage search preserves case - i18n (de+en): updated username_hint / username_invalid / ERR_USERNAME_INVALID to reflect the new rule Quick wins: - React Router v7 future flags (v7_startTransition + v7_relativeSplatPath) set on BrowserRouter — silences the upgrade warning - appUpdates.checkForUpdate: swallow benign network/fetch/"could not fetch valid release JSON" cases silently instead of console spam - osNotify: persist an "asked" marker in localStorage so the permission prompt only fires once per install (OS already persists the answer, but the plugin re-queries loudly otherwise)
