Objective: Build a single in-car Safety Lock Box for storing car keys with internet connectivity (SIM data or Wi-Fi) and controlled unlocking via Google Chat. Required Behavior (exact flow): Engine Off → Key Required: After the engine is turned off, the driver must place the key inside the lock box. Reminders: If the driver forgets to insert the key, send an email reminder to the driver. If the key is still not inserted within 1 hour, send an email reminder to the admin. Locking: After the key is inserted, the box locks. Unlock Authorization: The box will not open until the driver sends a Google Chat message containing “To Do list & Custody” or some specific words. Without this Google Chat message, the box must remain closed. Emergency Fallback: Provide a manual PIN (or similar code) for emergencies. When the box is opened with the PIN, send an email to the admin indicating the box was opened manually with a PIN. Connectivity: The system must connect to the internet via SIM data or Wi-Fi. Deliverables: Working Safety Lock Box fulfilling all behaviors above. Email notifications (driver reminder, admin reminder at 1 hour, admin alert on PIN use). Google Chat message check that controls unlocking (“To Do list & Custody”). Basic setup/usage instructions. Acceptance Criteria: Driver email is sent if the key isn’t inserted after engine off. Admin email is sent if key is still not inserted after 1 hour. Box locks after key insertion and remains locked until the required Google Chat message is sent. Emergency PIN unlock works and immediately emails the admin about PIN use. Internet connection works via SIM data or Wi-Fi. Please include a brief strategy to achieve this covering connectivity, notification flow, Google Chat based authorization, emergency PIN handling, timeline, and key risks/mitigations.
