[Pull request](https://github.com/microsoft/BCApps/pull/10205) · merged into `main` (BC30) on 2026-08-17 by martinsrui-msft · 6 files (+48 -3), 4 AL · obsoletion · tier official · reviewed (checked by Opus)

## What changed

- Four public GenerateTextCompletion methods in codeunit 7771 marked [Obsolete] and guarded with #if not CLEAN29
- Text completion implementation in codeunit 7772 and related parameter objects (7765, 7766) guarded with conditional compilation
- Authorization and SendRequest plumbing intentionally retained to avoid cascading compilation errors
- Text completion enum value left for follow-up deprecation
- Verified runtime compatibility: API continues working before CLEAN29 cleanup
