Servers and CLI

Package shape

Headless binaries (Linux services, Windows services, CLI). Ship as a single file or a directory; see Desktop. Store feeds are usually the wrong protocol.

Client duties

1. POST check when the process starts.
2. Poll afterward on your operations cadence. The product does not define a fixed interval. Honor Retry-After when present.
3. Without a Replacer: stage the verified file and let systemd / Task Scheduler / the orchestrator replace the running binary.
4. Optional POST .../telemetry/report; failures must not block the update.
