This project includes a hidden E2E auth bridge for deterministic local tests:

• window.__E2E_AUTH__.loginAdmin()
• window.__E2E_AUTH__.logout()

It is intentionally restricted to local emulator runs.

The bridge is enabled only when all are true:

1. import.meta.env.DEV === true
2. VITE_E2E_MODE === "true"
3. VITE_USE_FIREBASE_EMULATOR === "true"

If these are not satisfied, the bridge is not registered.

• Production auth model is unchanged (admin email check in Firestore rules).
• The E2E bridge is designed to be stripped from production bundle paths.
• Build validation fails deployment if production bundle contains:
  • localhost:9099
  • localhost:8081
  • __E2E_AUTH__
  • VITE_E2E_MODE

scripts/e2e/seed-emulators.mjs refuses to run unless:

• FIREBASE_AUTH_EMULATOR_HOST is set
• FIRESTORE_EMULATOR_HOST is set and uses port 8081
• project id is explicitly allowed (demo-project)

This prevents accidental writes outside local emulators.
