Choose one complete first source and its own blank. Preserve the first response before models; record earlier access and actual support. Offer a different unseen later source only after actual targeted teaching; otherwise hold it. The educator download reveals all stages and staff answers. Public labels and noindex do not provide protected access or secure assessment.
Educator navigation. Six alternative targets: own purpose/making; relations/possibilities; honest comparison; conditional actual source/how-why; conditional actual willing reception; own channel/operation choice. Choose for the available child/task/setting, never as learner types or a full-class circuit.
Follow the exact first → teaching → held different later sequence. Each selected stage has a full individual source and its own complete response blank. Keys and feedback are separate. A filled blank is not physical making, an actual source or an actual audience.
No secure-test, state approval, whole-code attainment or validated improvement claim. Private/no response/decline is described accurately; it is not an error or proof of mastery. No child identifier needs publication.
