+Issue #116 mechanically moves the copied `cadmin/` destination to `studio_courses/`, including
+its Python, test, template, and static namespaces. The source paths above remain the literal-copy
+provenance. `copied-files.tsv` now records each pinned `cadmin/*` source against its exact
+`studio_courses/*` destination, while the two-file target-owned `cadmin/` package contains only
+the accepted legacy URL adapter.
+
 The source root templates use a distinct destination so their byte identity is retained without replacing the unified website's root template shell. The manifest records this mapping.
 
 Allowlisted tracked roots are `accounts/`, `api/`, `cadmin/`, `course_management/`, `courses/`, `data/`, `e2e/`, `templates/`, and `scripts/`. This includes all original app migrations, tests, templates/static assets, management commands, compatibility API, cadmin, and source operational scripts referenced by characterization tests.
