pub fn handler_cross_caps(

    consumed: &[String],
    aliases: &HashMap<String, String>,
    flattened: &HashMap<String, String>,
) -> BTreeMap<String, String>

v0.15: the cross-context capabilities a context’s handlers reference, as deps_key → consumed_context. Shared with bynk-emit, not duplicated — see resolve_consume_prefix’s doc.
