## Why Network proxy enforcement on Windows requires the elevated sandbox backend. Silently selecting that backend for an unelevated configuration makes the effective sandbox differ from the configured mode. ## What changed - Reject enabled network proxy configurations on Windows unless managed requirements allow only the elevated sandbox and `windows.sandbox` resolves to `"elevated"`. - Preserve the configured sandbox backend during execution and validate proxy compatibility at config loading, sandbox setup, and process launch boundaries. - Defer this validation during cloud-config bootstrap so authoritative managed requirements can be loaded first. - Do not start or expose disabled Windows proxies, and render transitions to disabled networking as `<network enabled="false"></network>`. ## Testing - Cover Windows requirement and sandbox compatibility matrices, bootstrap behavior, backend selection, disabled proxy handling, and environment-context updates.
