Function render_norm 

pub fn render_norm(
    party: u64,
    opcode: u8,
    artefact_id: u64,
    frame: u64,
    expiry_unix32: u32,
) -> NQuin

Build a rights norm bound to the artefact’s identity: (party) OPCODE display(artefact) in a frame, optionally expiring at expiry_unix32 (0 = no expiry). The action target (object) is the artefact’s id, so this norm and the artefact’s situatedness fact share the artefact identity — the deontic and spatio-temporal queries are over the same artefact.
