The Open-Source Ethos for Hard Tech

Software learned that open source builds trust and speeds correction; Kronos applies the same ethos to a machine, with the boundaries hardware demands.

Borrowing a proven practice

Open-source software demonstrated something durable: code that anyone can read, run, and fix tends to be more trustworthy and more correct than code kept private. Kronos brings that ethos to a hard-tech program — publishing designs, data, and code under open licenses — because the same forces apply. Many eyes find errors; permissive licenses let the work spread; reproduction turns claims into shared results.

What carries over cleanly

• Open licenses on both content and code; see content under CC BY and code under Apache.
• Public version control and provenance, so the record's history is visible; see version control and provenance.
• Reproducible builds and runbooks, so anyone can rebuild the result; see reproducible pipelines.
• A bias toward disclosing problems early rather than hiding them until forced.

Where hard tech differs

A machine is not pure software. Some detail is genuinely sensitive, and a physical build cannot be forked in an afternoon. So the ethos comes with honest boundaries: a firewall that keeps economics and confidential material out of public artifacts, and a public/private split on the 3D model. See what we don't publish and the public 3D model.

The ethos, not just the license

Open source is a habit of mind before it is a license file: default to disclosure, invite correction, treat outside reproduction as the goal. That habit is what the rest of this section documents in practice, and what makes designing in the open a method rather than a slogan.

We took what worked in software and applied it to a machine — with the limits a machine honestly requires.
