pub fn project_transient_context(
ctx: &TransientContext,
) -> Result<TransientContext, String>Expand description
Project a live TransientContext into its owned
WIT mirror. Host→guest only.
Fallible only because of TR.3a’s args: an Args variant that has no WIT
form is a typed error rather than a silently-dropped field, which would
hand the builder none and have it build the wrong menu.
