Fact discipline first.

Selection Standards

• Events must be tied to the exact calendar date and year.
• Events should have durable historical significance.
• Digests should vary across geography, period, and category when possible.
• Uncertain or contested details are omitted, softened, or flagged for review.

Review Flags

Medium-confidence events require a review flag. Drafts with flagged items remain in review until an editor resolves the uncertainty.
