Media and live updates cross different resource limits. A file upload needs storage and type checks; an image needs a delivery budget; a live stream needs reconnection and ordering rules. Treat each as a specific contract rather than a generic byte pipe.
Topics in this track
- Safe File Upload Pipeline — Accept an inspection photo only after bounded parsing, permission, and type checks.
- Image Variants and Delivery Budgets — Serve pixels suited to the display box while reserving stable layout space.
- Server-Sent Events or WebSocket for Live Views — Choose one-way events or two-way messages from the actual interaction contract.
- Live Update Reconnect and Event Ordering — Reject older status events and reconcile gaps after a stream restarts.
