Official documentation verification
Use primary sources from docs.github.com, code.visualstudio.com, github.com/github, or learn.microsoft.com.
For each product claim:
- Capture the canonical URL.
- Record the date checked.
- Identify whether the capability is stable, preview, experimental, or availability-dependent.
- Avoid generalizing support from one harness to another.
- Prefer product documentation over blog posts and release announcements.
