+Code quality across popular open-source repos is **remarkably consistent**. Most repos score above 85 on code quality — solidly in the A and B range. The tools work. The linters work. Developers lint their code.
 
 What varies wildly — and what determines whether an enterprise should trust a dependency — is **governance**.

 ## The Evidence
 
 ### LangChain: 95.4 code, 45 governance
 
 The most popular LLM framework in the world. Used by thousands of enterprises. Scores 95.4 on code quality — excellent by any measure. But only 45/100 on governance:
 
-- No Code of Conduct
+- No CONTRIBUTING.md
 - No SECURITY.md
-- No DCO/CLA process
-- No issue/PR templates
+- No Code of Conduct
+- No DCO ([Developer Certificate of Origin](https://developercertificate.org/)) or CLA process
 
 Arbiter certification: **PROVISIONAL**. Not because the code is bad. Because the governance infrastructure doesn't exist.
 
 ### MONAI: The Gold Standard at 98.2
 
 NVIDIA's healthcare AI toolkit scores 98.2 — the highest of all 201 repos. Perfect governance: 100/100. LICENSE, CONTRIBUTING, SECURITY, Code of Conduct, issue templates, PR templates, CI/CD, DCO. Every box checked.
 
-This is what enterprises should require. And almost nobody does.

-### Sentry: 98.5 code, FAILED
+### Sentry: Near-Perfect Code, Still PROVISIONAL
 
-Sentry has the **best code quality** of any repo we tested: 98.5/100. But it **fails** certification because of 109 unpinned dependencies. The attack surface isn't the code — it's the supply chain.
+Sentry scores 98.5 on code quality — among the highest we tested. But it lands at **PROVISIONAL** because of 109 unpinned dependencies. Arbiter's dependency scoring penalizes unversioned dependency declarations because they make builds unreproducible and expand the supply chain attack surface. The risk isn't the code — it's the supply chain.
 
 ### Flask and Click: Foundational, PROVISIONAL
 
 Two of the most fundamental Python libraries. Flask powers millions of web apps. Click powers thousands of CLIs. Both score PROVISIONAL due to 45/100 governance. No Code of Conduct. No security policy. No DCO.
 
-If your enterprise depends on Flask, you're building on a library that doesn't have a documented vulnerability disclosure process.

+**Developer tools lead** — pytest, pip, tox. The people who build tools for quality also practice quality. **Cybersecurity tools** (pwntools, nmap, sqlmap, routersploit) all landed PROVISIONAL — strong code, weak governance artifacts. With only 4 repos in the sample, this likely reflects the tooling culture's bias toward speed over process rather than an industry-wide gap.
 
 ## What This Means for Enterprise AI Adoption
 
+These aren't academic distinctions. When AI tooling fails in production, the investigation often traces back to governance gaps, not code bugs.

 If you're evaluating open-source AI tools for enterprise use, stop asking "is the code good?" It almost certainly is. Start asking:
 
 1. **Is there a SECURITY.md?** Can you report vulnerabilities privately?
