   There are two more DEVELOPMENT.md references besides L304, and they don't all have the same fix.

   AGENTS.md	Reference	Resolvable?
   L268	[DEVELOPMENT.md](DEVELOPMENT.md#testing-on-linux-from-macos)	Yes. The section is now CONTRIBUTING.md § "Testing on Linux from macOS"
   L304	[development guide](/DEVELOPMENT.md)	Yes. CONTRIBUTING.md
   L272	See DEVELOPMENT.md "CPython Version Upgrade Checklist" section.	No. No such section has ever existed

   L268 and L304 are fallout from fc637a155 (#7914), which renamed DEVELOPMENT.md to CONTRIBUTING.md without updating AGENTS.md. Repointing them is enough.

   L272 was introduced already broken in 7a516c44c (#6728). Grepping every revision in history finds "CPython Version Upgrade Checklist" only in AGENTS.md and its predecessor .github/copilot-instructions.md, never in DEVELOPMENT.md. It is not in the wiki either. So the section was never written, and today this is a heading with no body:

   ### Building venvlauncher (Windows)
   
   See DEVELOPMENT.md "CPython Version Upgrade Checklist" section.

   Fixing that one needs the actual build steps written, or the heading removed.
