PROJECT ESTIMATOR / DISPOSABLE TEST / V3
PWA feasibility probe
Synthetic data only. These checks do not validate a physical device until run on that device.
Environment
Checking…
Offline shell: checking…
1. Offline storage
Save a marker, close the app, disconnect internet, and reopen. Its exact value must survive.
No read performed.
2. Email attachment
Prepare a synthetic package, then share it to your mail app. Sending and office receipt require separate observations.
3. Local Wi-Fi snapshot
Use the Mac agent’s LAN address on a phone, not 127.0.0.1. Keep the original PWA open. This tests authenticated read-and-store, not full bidirectional sync.
No transfer attempted.
Evidence
Export the observations after each test. The report identifies the environment and records actual outcomes; it does not infer email delivery or physical-device success.
