Video recording creates an obvious problem almost immediately: video files are big.
Before the recorder itself was even finished, we designed the cloud-storage system that would eventually protect completed recordings and keep them from filling the phone. A finished video would be saved locally first, placed in a persistent upload queue, uploaded in the background, and only considered removable after the cloud provider positively confirmed success.
The most important sentence in the prompt was essentially: if there is any doubt, keep the local file. Network failures, expired credentials, interrupted uploads and unknown states were not reasons to delete anything. Automatic cleanup would happen only if the user had enabled it and a verified remote copy existed.
This was one of the first places where the app’s evidence-preservation role shaped the engineering. Storage convenience mattered, but not as much as avoiding the catastrophic mistake of deleting the only copy of a recording.
