Cryptographic Evidence Gates

Direct answer

K12 publishes 80 bounded gate records across eight components; every component remains DEGRADED and no production cryptographic transition is authorized.

Static JSON record
Evidence and authority boundary. K12 publishes deterministic static models, signed offline reference bundles, synthetic fixtures, review records, custody receipts, public projections, and release-time comparisons. It does not perform live network acquisition, deploy software, operate a facility, make an award, authorize force, certify compliance, enforce production access control, or convert a signature into factual truth.

VERIFIED PROJECT IMPLEMENTATION

Cryptographic transition remains evidence-gated

K12 evaluates ten evidence gates for each component workbook and authorizes no production transition.

Scope: K12 deterministic local reference implementation.

Reference gate results are not production migration evidence.

Reference gate evidence does not prove algorithm strength, supplier support, interoperability, production migration, or deployment. K12 authorizes no production transition.
