Chronology Stress Tests (Open Questions)
- How should event pages distinguish direct documentation from narrative tradition when both are culturally important?
- Where should unresolved date windows be surfaced to avoid false precision in timeline hubs?
- How do we model "project duration" vs "event date" for works developed over many years (for example, portrait and notebook families)?
