Required Front Matter

At minimum:

Strongly recommended additions (helps later):

• canonical_url (if published online)
• summary (1–2 lines you write once; great for retrieval)
• entities (optional: curated tags like ["ATMTA","POLIS","SAGE"])

Rule: publication_date must be parseable ISO (YYYY-MM-DD or full YYYY-MM-DDTHH:mm:ssZ).
