Public context

What an implementation receives

# Single Activity Implement the normative single activity behavior for the ZergLang flow 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.
