/**
 * Reference-transfer contract — a PURE, deterministic role-separation emitter +
 * advisory. No I/O, no Date, no Math.random.
 *
 * Reference channels bleed (model-mechanics #6: "references bleed; always state
 * what must NOT transfer"; failure-atlas row 11: "Reference roles contaminate —
 * transfer/ignore clauses were absent"). A multi-reference packet should state,
 * per reference, what it CONTROLS and what must NOT transfer. This emits that
 * canonical clause and warns when a multi-domain packet lacks it.
 *
 * Harvested from the MIT `Emily2040/seedance-2.0` reference-transfer-contract
 * (@63b32dc). Advisory by construction — nothing here mutates a live payload.
