The problem
Most products confuse finishing with learning.
A video can end, a worksheet can be submitted, and a chapter can be marked complete while the underlying concept remains fragile. Serious learning needs a stricter standard.
Mastery engine
Progress only counts when the child can prove understanding.
This page is about the gatekeeping layer: how SupΣrLearnΣr decides whether a concept is secure enough to support harder work.

The mechanism
The system treats answers as evidence.
A concept becomes secure only when the child can retrieve it, apply it, and avoid the common trap answers that reveal shallow understanding.
The parent view
Parents see readiness, not activity.
Instead of asking whether the child studied, parents can see which foundations are secure enough to carry future concepts.

Parent takeaway
Your child moves ahead because the system has evidence, not because the lesson timer ended.
