 ## 7. Direct `Repo.get` in `BDS.Desktop.ShellLive`
 
-**Status:** open. 10 call sites verified.
+**Status:** ✅ done (2026-05-01). `Repo.get/2` and `Repo.get!/2` no longer appear in `BDS.Desktop.ShellLive` or its submodules. ShellLive entity reads now go through context APIs (`Posts.get_post/1`, `Posts.get_post!/1`, `Media.get_media/1`, `Templates.get_template/1`, `Scripts.get_script/1`, `AI.get_chat_conversation/1`, and `Settings.get_global_setting/1` / `put_global_setting/2`). Added a regression test that scans ShellLive source for direct `Repo.get` calls.
 
-**Plan:** add the missing context functions (`Posts.get_post_with_translations/1`, etc.) and replace each `Repo.get(Schema, id)` with the context call.
+**Rule:** ShellLive modules may use `Repo` for query-shaped read models where no context abstraction exists yet, but direct primary-key entity fetches belong in context modules.

+- **Direct `Repo.get` in `BDS.Desktop.ShellLive`**: added context helpers for primary-key reads (`Posts.get_post/1`, `Media.get_media/1`, `Templates.get_template/1`, `Scripts.get_script/1`, `AI.get_chat_conversation/1`) and introduced `BDS.Settings` for global editor settings. Replaced all ShellLive `Repo.get/2` and `Repo.get!/2` calls across the main shell, tab helpers, CLI sync, panel renderer, chat message build, code entity editor, post editor, media editor, overlay components, post metadata, and settings editor. Added a ShellLive regression test that scans source files to keep direct `Repo.get` calls out. Section 7 is closed.

 - **God modules**:
   - `BDS.Maintenance` 810 → 141 (83 %). Submodules under `lib/bds/maintenance/`: `Progress` (45), `FileScan` (158), `DiffComputation` (93), `DiffReports` (315), `Repair` (145). Coordinator keeps the 4 public entrypoints (`repair_metadata_diff/4`, `import_metadata_diff_orphans/3`, `rebuild_from_filesystem/3`, `metadata_diff/2`); submodules wired via `import only:`.
   - `BDS.Scripting.Capabilities` 1715 → 194 (89 %). Submodules: `Util` (301), `Posts` (270), `Media` (254), `Crud` (284), `Projects` (204), `AppShell` (134), `Bridges` (176). Public `for_project/2` preserved.
