 # FAQ
 
-## Why add a full pack validator?
+This layer does not prove pedagogical adequacy. It is a heuristic signal layer for likely misalignments.
-
-Because import safety is not only about whether files exist. It is also about
-whether the pack makes sense as a Didactopus artifact set.
-
-## How does this help with the activation-energy problem?
-
-It reduces uncertainty at a crucial point. Users can see whether a generated pack
-is coherent enough to work with before losing momentum in manual debugging.
-
-## What does it validate?
-
-In this scaffold it validates:
-- required files
-- YAML parsing
-- metadata presence
-- duplicate concept ids
-- roadmap references
-- project prerequisite references
-- rubric structure
-- weak concept entries
-
-## Does validation guarantee quality?
-
-No. It checks structural coherence, not whether the pack is the best possible
-representation of a domain.
-
-## Where are validation results shown?
-
-They are included in import preview results and surfaced in the UI.
