What an implementation receives

# Broadcast Scalar Implement the normative broadcast scalar behavior for the ZergLang compute domain. Preserve deterministic ordering, typed failures, ownership transfer, and exactly-once cleanup required by the cited clauses. Submit the complete source closure matching `interface.zli`. Public cases are examples, not an exhaustive specification. Do not use ambient I/O, time, random state, or undeclared capabilities.
