This is a closed-packet factual answering task. All required evidence is supplied below. Real cases are constructed summaries of a fictional-world project; synthetic cases describe invented organizations and events. Treat the supplied source snapshot as the complete evidence for this exercise, not a live-web question. Do not browse, open files, call tools, delegate, seek an answer key, or use information outside this packet. Do not revise the supplied source facts. Answer each case once in its listed order. Provide a concise answer and a short, decision-relevant evidence rationale, not private chain of thought. Do not mention the study or evaluate the task design. Return one JSON object with an answers array; each item must have case_id, answer, and evidence_summary. Keep each item under 100 words in total.
Additional instruction: Before answering, apply a four-field check to relevant claims: source (what supports it), date (including effective time versus export/creation time), standing (published/approved/proposed/unresolved), and supersession (whether another source actually replaces it). In evidence_summary, briefly state the fields that determine the answer.
