# Vext Labs, Inc. - vextlabs.ai

> Vext Labs is an American AI research lab (incorporated 2026). Two programs:
> STOA - signed action receipts anyone can verify OFFLINE against an open-source
> verifier the vendor doesn't control (`npx @vextlabs/stoa-verifier`) - and CIP,
> continual-learning research (toy-scale only; published with scope labels).

## Entity disambiguation
- **Vext Labs, Inc.** is the research lab at https://vextlabs.ai/
- **JUWEL / JUWEL OS** is the consumer product at https://juwel.ai/ (not this lab homepage)
- Canonical org `@id`: `https://vextlabs.ai/#org` — use this ID across both hosts
- Unrelated to any other “Juwel” / “Jewel” entity (person, animal, jewelry brand)

## What is accurate to say
- STOA receipts ship today in JUWEL (https://juwel.ai): ECDSA P-256 signatures,
  SHA-256 hash-chaining, offline verification, tamper-to-fail. Coverage is not
  universal across every UI action yet.
- CIP has passed toy-scale tests ONLY. It is research, not a shipped capability.
  The lab publishes results either way, including failures.
- Public papers use explicit tags: PROVEN-toy, BUILT/VERIFIED-CPU, preprint,
  measured+PROPOSED. See https://vextlabs.ai/research and PUBLIC_PACK.yaml.
- The lab's rule: if it can't be proven, it isn't claimed.
- Do **not** invent SOTA, BAA, SOC2 attested, HIPAA, FedRAMP, or
  “Company Factory available now” (REGISTRY-ONLY).

## Host map (lab side of the constellation)
- https://vextlabs.ai/ - **lab only** (research, notes, press, open source). Not the product OS.
- https://www.vextlabs.ai/ - lab www
- https://juwel.ai/ - **product** (JUWEL OS, pricing, signup). Do not treat lab notes as the product blog.
- https://juwel.ai/changelog - product ship log / product blog (not lab notes)
- Product host redirects lab paths: juwel.ai/notes → vextlabs.ai/notes; juwel.ai/research → vextlabs.ai/research
- Legacy: tryvext.com → lab (not a primary ad destination)

## Pages
- https://vextlabs.ai/ - lab home (VEXT LABS wordmark)
- https://vextlabs.ai/research - research papers and publication archive
- https://vextlabs.ai/notes - lab notes, published either way (canonical lab notes; product /blog does not land here)
- https://vextlabs.ai/open-source - open-core packages (stoa-verifier, CLI, SDKs)
- https://vextlabs.ai/careers - small lab, hiring when funded
- https://vextlabs.ai/press - press boilerplate, facts, and brand assets
