K-12.
K-12 is the only universal substrate-formation site (mandated universally; delivered unequally) the state already operates. Six interventions: two on measurement and curriculum (A, C), one on the developmental window (B, the lead), two on the equity preconditions (D, E) that prevent the others from hardening tier structure, and one on AI literacy (F) — keeping human judgment at the center as intelligent systems enter the classroom.
Each intervention page carries a public five-field card and a deep panel with twenty-five structured fields. The deep pages are calibrated for the school board member, the legislative staffer, and the journalist. The cards are calibrated for the Tuesday-morning advocate.
The six interventions below sit within a larger landscape: 64 K-12 substrates across 7 families, with 10 causal bottlenecks flagged as Phase 2 priority candidates. Use the map to see which substrates each intervention engages and where the open intervention surfaces are.
Stop measuring what's cheap. Start measuring what's load-bearing.
Bell-to-bell phone-free K-12. Reclaim the developmental window.
AI can write the essay. Only humans can decide it was worth writing.
Take phones out, put substrate back. Don't reform-as-extraction.
The kids being measured and the parents whose mobility depends on the measure must have standing to define it.
The test isn't whether students can use AI. It's whether they can keep themselves at the center of it.
A and C are reform interventions; without D and E, they harden the existing tier structure — the sorting of kids by what their families can afford to provide at home. B (the lead) restores the developmental window during instructional hours; without D, it does not reach the home. F (AI literacy) pairs with C and B and depends on D: the evaluation skill is exactly the capacity that separates "human-plus" AI use from offloading, so without provisioning it becomes another advantage only the best-resourced families can buy. The framework's claim is that interventions ship paired — substrate restoration (the conditions a childhood runs on), not extraction-as-reform (stripping a resource without replacing it).
Intervention F ships with a classroom instrument and an alignment map. The student Diagnostic-Ladder curriculum is the gradeable move for evaluating any AI output. The crosswalk with Arizona's 2026 K-12 GenAI guidance shows where KTP supplies a mechanism, where it's cite-ready, and where the guidance leads and KTP defers.
