Keep each source stage clear
The complete educator bank is planning material, not a secure child-only archive. Give a learner the selected own/source/paper edition after teaching/exposure review. Do not give the whole seed/archive/staff set if later information must remain unseen. Later sources, alternatives and keys are not linked or preloaded from a first own page. This is educator custody; hiding a panel would not secure a whole bank.
C03/C11/C16 first readers and first V02/V06 art/alternatives load no later body. Release the separate complete later card after wanted first idea offered/saved or declined; absent comparison stays unelicited. The desk loads only ordinary C01 help, not later or held cases. Exact optional kept versions never become a score or old prediction by themselves.
Release C03 later · Release C11 later · Release C16 later. These are educator doors after the first opportunity.
