What We Don't Publish

Openness has a boundary: public artifacts carry the physics record and never economics or confidential material, and the boundary is machine-enforced.

A stated, enforced boundary

Designing in the open does not mean publishing everything. Kronos draws an explicit line: public artifacts carry the physics and engineering record, and never carry economics or confidential material. Stating the boundary openly — and enforcing it in code — is itself part of the honesty. A reader is never left to wonder whether something was silently withheld.

What stays out of public artifacts

• Economics of any kind: no prices, costs, funding, valuations, or financial projections appear in public papers, the technical library, the 3D model, or media.
• Confidential material: legal, personnel, and other protected content never enters the public or publication corpus.
• Sensitive design detail: some geometry is stripped from the public 3D build rather than shipped; see the public 3D model.

How the boundary is enforced

The firewall is not a matter of remembering to be careful. A verification step checks that a public artifact is clean before release — that no excluded content is present — and blocks the release otherwise. See the verify function. Enforcing the rule in tooling is what makes it reliable across a corpus of over a thousand pages.

Why exclude economics specifically

The public record's job is to let readers check the physics. Economics belongs to a different conversation and a different audience, and mixing it into the technical record would muddy exactly the claims we want reproduced. Keeping it out sharpens the open science rather than limiting it. The honest gates are physics facts and are never translated into cost; see the honest gates.

We publish the physics fully and the economics not at all — and we check every artifact to be sure.
