Three tenses, nine metrics. Unseen metrics stay unseen; the grade never fakes a number. Proxy era: provisional values, marked. Weighed as a project business: prior from its industry code (SEC 1731, Electrical Work); the filing read can change it. All three tenses have at least two readings, so the archetype blend applies as printed.
