The WinRT rich toast (reply box P5-41, click-to-open-room P5-35) was inert on
Windows: CreateToastNotifier needs the process under an AppUserModelID mapped to
a Start-Menu shortcut, and none was registered — so it errored and silently fell
back to the plain plugin toast.
New native/aumid.rs (Windows-only; no-op elsewhere), called first in
native::setup: (1) SetCurrentProcessExplicitAppUserModelID("LotusGuild.LotusChat"),
(2) install/refresh a Start-Menu "Lotus Chat.lnk" carrying PKEY_AppUserModel_ID,
reusing jumplist.rs's IShellLinkW + IPropertyStore + PROPVARIANT + IPersistFile
pattern (best-effort; failures logged + swallowed). toast.rs now binds the
notifier via CreateToastNotifierWithId(AUMID).
CI-compile-only (windows runner); runtime needs a Windows build to confirm the
toast shows a reply box + opens the room. windows-crate 0.61 symbol assumptions
(IPersistFile, SetCurrentProcessExplicitAppUserModelID, PROPERTYKEY,
GUID::from_u128, CreateToastNotifierWithId) validated by CI — all mirror existing
jumplist.rs usage where possible.
