This is an editable **mixed source bank**. It contains staff-only keys, whole question recipe/data, held sources and technical files. It is not a closed child download or secure assessment system; an educator must select only ordinary practice or one complete held stage for the intended reader. Staff sources are deliberately behind the educator door in these menus, with every item classified in SOURCE-MANIFEST.json. Future native/website curators must preserve the role boundary.

Finite original author delivery awaiting different whole source critique. National focus M01/M02/N05 with selected additive components, not whole Year 3/state completion or observed learner attainment. All forty annual organiser rows remain intact. No account, autoplay, external assets, response upload or automatic updates; optional adult links are reader-selected. No translations or local cultural permission claimed.
