Windows packaging is planned after signing is complete. The app surface and write-confirmation rules are the same across platforms.

Inspect the repositoryBefore first run
Connect a tenant and choose a model provider.
OpenAdminOS uses MSAL for Microsoft 365 tenant consent and Microsoft Graph access. Local model providers keep prompts and tenant context on the workstation. Hosted providers are optional and labeled before tenant context leaves the device.
Read-only agents can run after consent. Write agents always stop at a diff confirmation screen before changing tenant state.
