OPS.3:9 - Consequences

The pattern produces trustworthy units for measurement and policy and makes cross-view reconciliation possible. It also localizes repairs: a stale record source, changed identity rule, missing relation, or uncertain state claim can reopen without rebuilding the whole operating account.

The cost is refusing convenient conflations. Some metrics and historical analyses become unusable because their unit identity or source coverage cannot be recovered. That loss is explicit rather than hidden in a precise-looking chart.
