## Research Software — Not Commercial Software

RenatoDesignSystem™ apps are **research artifacts**, not commercial products.

They are authored through **Iterative LLM Co-Authorship (ILCA)** — a collaboration between Phil Renato and Claude (Anthropic) — as an active, ongoing design inquiry. The apps are shared publicly in that spirit.

**Before using any of these apps, understand:**

- They are **not warranted, supported, or validated** for production, safety-critical, regulated, or professional work.
- They may contain bugs, broken features, unstable APIs, or outputs that look plausible but are wrong.
- Third-party dependencies are attributed in each app's `NOTICES.md`, but **no formal IP clearance** has been performed beyond that.
- Domain-specific outputs (footwear lasts, jewelry geometry, CFD results, literary critiques, etc.) are **exploratory** — do not use them as the basis for manufacturing, legal, medical, financial, or other consequential decisions without independent verification.
- The models and APIs some apps rely on are subject to their own providers' terms, which may change.

**If you use an RDS app, you accept these terms.** If any of the above is a problem for your use case, **do not use the software for that purpose.**

This is the condition under which the work is shared openly. Treating it as more than research is your risk, not Phil's.


## PUFF in particular

PUFF estimates what a hydraulic press will do to a sheet of metal. A hydraulic press stores and
releases forces that break tooling and bodies. Nothing this app says makes a setup safe: keep
tooling fully supported by the platens, never overhang acrylic, keep hands clear, wear eye
protection, and follow the press maker's instructions and Cynthia Eid's "Hydraulic Press Safety"
handout (https://cynthiaeid.com/handouts/). The numbers here are closed-form approximations
with stated, uncalibrated coefficients; they are for learning what changes what, not for
deciding that a die or a press is within its limits.
