Product frame
The system has to handle real devices, real playback sessions, and real maintenance cost. Playback stability, Apple TV focus, subscriptions, FAQ, release cadence, and support all belong to the product surface.
Current Project · Media runtime ecosystem
Syncnext
Syncnext is not just a player. It is a media runtime built around playback reliability and flexible content sources. The design question is where each boundary belongs: native app, playback bridge, external source, plugin, or documentation.
Narrative
Design and engineering judgement
Engineering frame
The main app keeps the product and interaction boundaries stable. The public SyncnextHybrid package isolates AetherEngine, the AVKit timeline, and audio analysis, while the API, plugin reference, and networking helper absorb volatility around external content sources.
Design frame
The public story should present a small product ecosystem: not a feature checklist, but a maintained system with clear boundaries and explanations.
