Supporting work / native mediaThe media infrastructure behind AfterPlay's court-session recorder: multipart transfers, persistent recovery state, background work, and private playback.
The interface distinguishes a saved local recording from a completed upload and a playable cloud session. Queued transfers and retry states stay visible, and local media is retained until the server confirms finalization.
SwiftUI provides the product surface while AVFoundation anchors the media pipeline, keeping platform-specific media behavior close to the work that needs it.
Background URLSession handles eligible transfers while persisted multipart progress supports reconciliation after relaunch. Recovery must account for partial completion and server state; background execution is an opportunity provided by iOS, not an unlimited-running guarantee.
Cloudflare D1 and R2 separate structured state from large media objects, giving the engineering model a clear place for metadata, durable status, and object storage.
