## Title

    Preserve continuous event coverage with explicit end semantics

## Body

    FACT: The examined cycle found that continuous records were lost when collection used only a start date, while date-only ends were inclusive and timed ends were exclusive. INFERENCE: End semantics are part of domain truth, not presentation detail. RECOMMENDATION: Model date-only, timed, continuous, and unknown coverage separately and preserve the policy revision in publication identity.
