 A few things worth knowing before you debug a failure:
 
-- **The suites adopt `.venv-e2e` rather than provisioning their own venv**, which is most of the runtime.
-  If the Python extension does not offer it, the run still passes but takes several minutes longer and
-  logs `no interpreter under .venv-e2e was offered` — grep for that first when a run is unexpectedly slow.
+- **The suites run against `.venv-e2e` rather than provisioning their own venv**, which is most of the
+  runtime. When it is missing the pinned interpreter does not exist, so the first run stops on the
+  install-consent modal and the suite times out there — re-run `npm run setup:e2e:venv` first.
+- **A suite that needs a different interpreter** writes its own workspace `.vscode/settings.json`;
+  `python.defaultInterpreterPath` is `machine-overridable`, so the workspace value wins over the pin.
+  `suite/interpreter/` does this to get an interpreter without the toolkit.
 - **Screenshots of failures** are written to `<test-resources>/screenshots/` and uploaded as CI artifacts.
 - **CI shards by directory**, one job per group, so a new group directory must also be added to the matrix
   in `.github/workflows/e2e.yml` — the `verify-coverage` job fails the build if a group ran nowhere, or if
