In `@backend/src/db/daos/groupDao.js`:
- Around line 38-51: The addUserToGroup function has a race condition:
concurrent calls can both see no group and create duplicate Group documents; fix
by making the create-or-update atomic — either add a unique compound index on
(scenarioId, "users.group") on the Group model and handle duplicate-key errors,
or replace the read-then-create flow in addUserToGroup with an atomic
findOneAndUpdate using the Group model (match by scenarioId and "users.group":
user.group) with upsert: true and a $push of user (or $addToSet if duplicates
should be avoided), and remove the separate createGroup path; ensure you handle
the returned doc when upsert creates a new document and catch duplicate-key
errors if you also add the DB-level unique index.
In `@backend/src/routes/api/__tests__/groupApi.test.js`:
- Around line 73-78: The afterAll cleanup uses server.close with an async
callback which isn’t awaited; change it to await server.close via a Promise
(e.g., await new Promise(resolve => server.close(resolve))) and then
sequentially await mongoose.disconnect() and mongoServer.stop() outside the
server.close callback so mongoose.disconnect() and mongoServer.stop() reliably
complete; update the afterAll block and references to server.close,
mongoose.disconnect, and mongoServer.stop accordingly.
In `@frontend/src/features/groups/AddGroupMemberModal.jsx`:
- Around line 117-123: The AddGroupMemberModal's submit button currently only
uses visual styling but stays clickable; update the button in
AddGroupMemberModal.jsx to set the disabled attribute to the same condition
(disabled={ !isSubmittable || isSaving }) so it becomes non-interactive for
keyboard/screen readers, keep the className toggle for styling, and ensure
handleSubmit early-returns when !isSubmittable || isSaving to avoid accidental
invocation when disabled.
In `@frontend/src/features/groups/ManageGroupsPage.jsx`:
- Around line 172-188: The addMember function currently groups the POST and
refetch in one try so a refetch failure reports "There was an error adding the
member"; change this so the POST (api.post in addMember) is awaited in its own
try block and, on success, show the success toast and close the add modal
(setIsAddMemberOpen(false)), then perform refetch() in a separate try/catch: if
refetch fails, show a distinct warning/info toast indicating "Member added but
failed to refresh list" (and log the refetch error) rather than the generic add
error; preserve the finally behavior setting setIsAddingMember(false) and ensure
errors from the POST still show the original add-error toast and log.

172-194: ⚡ Quick winPast review concern properly addressed; consider more actionable guidance on refetch failure.
The separation of POST and refetch is well-implemented—the member-add success is now correctly reported even if the subsequent list refresh fails.
One small UX refinement: the refetch-failure message on line 183 tells users what happened but not what to do. Consider prompting them to reload.

i dont quite understand this field and the logic associated with it . what does the "group" of the group actually mean?

Issue
Managing scenario group members required exporting the group CSV, manually adding a row, and importing it back into the application.
Solution
Added a UI flow on the manage-groups page to add a single member directly from the application. This includes a modal for name, email, role, and group number, plus a backend endpoint that appends the member without rebuilding all groups. The endpoint validates required fields, duplicate emails, and duplicate roles within a group.
Risk
Low to moderate. This adds a new group mutation path, so the main risk is inconsistent group/role data if validation misses an edge case. Existing CSV import behaviour is unchanged.
