C.27.TA:1 - Problem Frame
Distinguish two concerns. One concern is temporal-claim adequacy: whether an authored claim about speed, rhythm, rate-change, recovery, or stabilization can carry a named use. The other concern is positive temporal subject matter: windows, duration, cadence, synchronization, freshness, currentness, inertia, effort over time, recovery, stabilization, and trajectory as aspects of objects or claims.
C.27.TA addresses the second concern. It lets a practitioner state what temporal aspect is in play without immediately opening an adequacy card, a dynamics model, a work plan, a causal-use record, or a transformation statement.
