@@ -18,42 +18,4 @@ files leave as downloads. **Nothing is written on the server**, and there is no
 endpoint that could write anything. That is what makes it safe to host without a
 login.
 
-Note this differs from the local development setup in the course folder, where
-`edit_server.py` accepts `POST /__save` and writes sheets straight to disk. That
-server is not deployed here, and must not be — reachable without a login it
-would be a write primitive for anyone who could load the page.
 
-## How it is served
-
-`workshop/src/routes/projects/exercise-builder/app/[...file]/+server.ts` reads
-this directory at request time. Consequences worth knowing:
-
-- **Updating the builder does not need a site rebuild.** Sync new files here and
-  a reload picks them up (responses are `no-cache` with an mtime-based ETag).
-  A rebuild is only needed when the landing page or the route itself changes.
-- Only recognised asset extensions are reachable, and paths are contained to
-  this directory — so nothing outside `app/` can be requested.
-- `.js` is served as `text/javascript`, without which browsers refuse ES
-  modules outright.
-- The route injects `<base href="/projects/exercise-builder/app/">` into the
-  served HTML, so the builder's relative URLs resolve whether or not the visitor
-  typed a trailing slash.
-
-Override the location with `EXERCISE_BUILDER_ROOT` in the workshop `.env` if it
-ever moves.
-
-## Updating
-
-Edit the files here. There is no build step and no sync — a reload picks the
-change up, for the reasons above.
-
-## Source of truth
-
-**This directory.** The builder was developed in the BI122G course folder on
-the workstation (`/Muspelheim/Employment/HiS/Teaching/BI122G`) and pushed here
-by `deploy_builder.sh`. That arrangement has ended and this installation is now
-canonical: **do not run `deploy_builder.sh` again**, as it would overwrite this
-directory with the older course-folder copy.
-
-The course folder still holds `test.mjs`, a Node test harness that was never
-deployed here — it needs `linkedom` and is no use in a browser.
