vs its business-model standard
Three tenses, nine metrics. Unseen metrics stay unseen; the grade never fakes a number. Proxy era: provisional values, marked. Weighed as a product business: prior from its industry code (SEC 3661, Telephone & Telegraph Apparatus); the filing read can change it. All three tenses have at least two readings, so the archetype blend applies as printed.
