pub fn project_picker_context(
ctx: &PickerContext<'_>,
) -> Result<PickerContext, String>Expand description
Project a live PickerContext into its owned WIT
mirror (§4.2). Host→guest only: the host builds this at init time; the
guest never sends a context back. A non-UTF-8 path anywhere in the context
is a typed error (§4.4), never a lossy encoding.
