K-12 core-literacy classroom design

Design or reshape one persisted OpenMAIC stage around the Chinese curriculum standards' core-literacy model. The deliverable is the classroom itself: pages, roles, learner activity, assessment evidence and narration written into the stage. Do not produce a Word lesson plan, a lesson.json, HTML, or instructions for running local render scripts.

The invariant is:

authentic context → performance task → learning activity → observable evidence → transfer

stage-design still governs the persistence sequence for a new stage. This skill governs the pedagogy and the information carried in every page brief. If the stage already has pages, edit it surgically under the pro-editing rules; do not create a duplicate stage.
