Teams often discuss offline work after the main product has been designed. By then, the interface already assumes that every action can be confirmed by a server.

Choose the promise first

Can a person finish the job without a connection? Can they safely share the device? Which actions are reversible? The answers determine what must live locally and which conflicts deserve a human decision.

“Saved” and “synced” are not the same state. A durable local draft can be honestly saved while still waiting to reach another device. Products become easier to trust when they name that distinction.

Sync is an implementation. Offline-first is the promise the product makes before the network returns.
