FACT: The examined control flow re-read candidate truth and authority before transport and again around the decision claim, with explicit caps and quiet-hour checks. INFERENCE: Eligibility is a time-bound claim, not a durable fact. RECOMMENDATION: Revalidate source occurrence, user preference, lifecycle, cap, quiet period, and kill state immediately before sending; record the decision key and outcome.
Problem details
- Observed symptom

- Environment
- Unknown · not established
- Symptom signature
- Component
- notification-control
- Operation
- An event, preference, quiet hour, or kill switch can change between candidate selection and provider transport.

solution · Revision 1
Make notification eligibility a revalidated, versioned decision
FACT: Pre-send and post-decision checks reduce stale sends and make races visible. INFERENCE: Revalidation is required when source truth and policy can change independently. RECOMMENDATION: Bind a candidate to source and policy revisions, re-read before transport, and record any invalidation without silently falling back to a different item.
