-- **Structural wart, not yet fixed:** `ingest.cpp` / `ingest.h`, plus `ext_keys.h`
-  and `resource.h`, physically live at `src/` root rather than under
-  `shell/actions/` — Phase Q's reorg did not re-home these files into
-  `core/`/`shell/`/`app/`. `ingest` is documented here as its nearest sibling by
-  role, but the files themselves are not in this directory. This is a code
-  organization issue, not a documentation one — see Open questions in the
-  originating dispatch report.
+- **Structural wart, partly closed:** `ingest.cpp` / `ingest.h` now live in this
+  directory. `ext_keys.h` and `resource.h` still sit at `src/` root: `ext_keys.h`
+  is consumed mostly from `shell/instrument/`, so it is not this directory's to
+  claim, and `resource.h` is a build input paired with `src/resource.rc` (the SWELL
+  resgen step) rather than a shell module.
 - Media-Explorer import is single-file, pull-on-action (`OpenMediaExplorer` +
   `MediaExplorerGetLastPlayedFileInfo`) — there is no enumerate-selected-files or
   register-a-drop-handler API on the Media Explorer surface.
