Documented features match

Build extensible and data-driven AL test suites - high confidence (llm). Docs say: General availability, roadmap id 573333. Reusable data sources

Docs checked on 2026-10-02: the match is against Microsoft's what's new pages for the wave as they were on that date. Microsoft keeps filling the documentation, so "no documented item" can go stale. The wider product documentation on learn.microsoft.com was searched for this feature on the same date; the feature's data lists an article when one was found.
