Installers are entitlement-checked: sign in with the account that holds your license and the link resolves to the newest release your update window covers. Every artifact publishes a SHA-256 so you can check what you received before you run it.
Windows 11 x64
The shell that has been through hardware runs: packaged WebView2 UI, bundled sidecar, native volume events, and a clean five-process lifecycle on a real cart.

- internal certificate — not public-trust signed

- hardware-tested · prerelease
Current prerelease packages are signed with an internal certificate trusted only on the commissioning machine. Windows will warn you. Public-trust signing and a clean-machine pass are still outstanding — check the SHA-256 below before installing.
macOS 14+ · Apple silicon
The application runs on macOS in development, but no macOS package has passed the hardware gate. We are not going to publish an installer we have not tested on a cart.

When the first macOS release is published it appears here and on your account page, at /api/download/latest-entitled/darwin-aarch64, under the same entitlement rules.
Who these links work for.
A purchase is required. There is no trial build yet — when there is one, it will be a real, full-function build with a stated time limit, not a crippled demo.
If you are signed in and licensed, the link above redirects to a short-lived URL for the newest stable release published on or before your update cutoff. If you are not, it answers with the reason — sign-in required, no license on file, or no entitled release — rather than a generic error. Releases, checksums and your license file all live on your account page.
The installed application checks for updates itself and is only ever offered releases your license entitles you to. Nothing you already installed stops working when an update window ends.
Verify what you downloaded.
Every artifact has a published SHA-256. Compare the hash of the file you received with the one shown beside that release on your account page. If they differ, do not install it — tell us, and we will treat it as an incident rather than a support ticket.

The hashes above are illustrative formatting, not the checksum of any real artifact. The authoritative value is the one published with the release you downloaded.
Installation and first-run guides — including the macOS build and install path — are published alongside each release on your account page, and the first-run screen in the application walks a new cart through prerequisites before it will plan a transfer.
