The Classification Firewall

A structural separation ensures public materials never carry classified, controlled, or weapons-relevant content.

A firewall, not a judgment call

The safest way to keep sensitive content out of public materials is a structural firewall rather than a case-by-case judgment made under deadline. Kronos separates public and confidential content at the source: public repositories and this library are built to carry only public, conservative material, and confidential content lives elsewhere with verification that it cannot cross over.

How the firewall works

• Confidential material is authored and stored on the private side, never in public repositories.
• Automated verification checks public artifacts for markers of economics, classified, or controlled content before release.
• Two-edition documents use explicit markers so a public-light edition cannot inherit confidential paragraphs.
• Legal and export-control content is kept strictly out of publication and website material.

Why it is enforced automatically

Human vigilance fails under volume and time pressure; a build-time verification step does not. This library, for example, is generated under rules that forbid economics and enforce honest gates, and the same class of check keeps classified and weapons-relevant content out. The firewall is what makes it safe to publish openly: because the boundary is structural and verified, the program can be genuinely transparent about the science and the readiness story without risking a sensitive disclosure.

For a defense counterpart, the existence of an enforced firewall is itself a readiness signal — evidence that the organization can handle sensitive information with discipline.
