https://www.offlineprotocol.com/blog Engineering notes and perspective from the team building the transport, identity, and coordination layer for devices beyond reliable connectivity. en-us Wed, 29 Jul 2026 00:00:00 GMT https://www.offlineprotocol.com/blog/the-network-is-an-undeclared-dependency https://www.offlineprotocol.com/blog/the-network-is-an-undeclared-dependency Modern software treats the network as a fact of nature rather than a dependency. Everywhere the work actually happens, that assumption quietly fails, and the case for offline-first is really the case for declaring it.

The more useful unit is dollars per hour, which reframes offline-first from a nice-to-have into a line item.
