Deployment requirements (administrator) — this screen does not secure the backend
This page enforces verified e-mail and a configured App Check key only as a client-side convenience: anyone with this page's public configuration can bypass the page and call Firebase directly. Real protection comes only from the following, all of which must be set up and tested outside this file (none was changed or verified by it):
- Owner-only Firestore rules — deploy the RC3
firestore.rules(verified e-mail required,users/{uid}/scenarios/{id}only forrequest.auth.uid == uid, every other path denied). - Emulator tests passing against those exact rules (unauthenticated and unverified denied; user A cannot list, read, write or delete user B's scenarios).
- Public sign-up disabled in Firebase Authentication, so accounts exist only when an administrator creates them.
- Verified, approved users only — administrator-provisioned accounts; the rules require a verified e-mail address (a user the administrator has not approved must not be able to sign up or be created by anyone else).
- App Check: set
RM_APPCHECK_CONFIG.siteKeyin this file to your reCAPTCHA site key and enforce App Check for Authentication and Firestore in the console. With the placeholder key still in place, cloud sign-in and cloud scenarios are disabled by this page (the calculator keeps working).

⚙ ARM Terms & Cap Structure
A 5/1 ARM is fixed for 5 years, then adjusts every 1 year. The FIRST adjustment is capped by the initial cap; every later annual adjustment is capped by the subsequent cap; total increase from start rate is capped by the lifetime cap (e.g. a "2/1/5" ARM = 2% initial / 1% subsequent / 5% lifetime).
