Bug: A new migration 0002_* conflicts with an existing migration of the same number, creating a branched history that will cause Django's migrate command to fail.
Severity: CRITICAL
Suggested Fix
Resolve the conflicting migrations. This can be done by re-numbering the new migration (e.g., to 0004_*), updating its dependencies to point to the latest existing migration, and then running python manage.py makemigrations --merge to create a merge migration that resolves the divergent paths.

Location:
backend/questionnaires/migrations/0002_questionnairepermission_questionnairemembership_and_more.py#L15-L17
Potential issue: The pull request introduces a new migration
`0002_questionnairepermission_questionnairemembership_and_more.py` which conflicts with
an existing migration `0002_alter_questionnaire_document.py`. Both migrations share the
same number and depend on `0001_initial`, creating a branched migration history.
Django's migration system cannot resolve this conflict automatically and will raise an
`InconsistentMigrationHistory` error during deployment. This will prevent migrations
from running and block the application from starting.

Bug: The QuestionnaireMembershipAdmin search_fields references questionnaire__slug, but the slug field is removed from the Questionnaire model in a later migration, which will cause a FieldError.
Severity: HIGH
Suggested Fix
Remove the 'questionnaire__slug' entry from the search_fields tuple in the QuestionnaireMembershipAdmin class located in backend/questionnaires/admin.py. Replace it with a valid field from the Questionnaire model if search functionality on a related field is still desired.

Location: backend/questionnaires/admin.py#L29
Potential issue: The `QuestionnaireMembershipAdmin` class defines `questionnaire__slug`
in its `search_fields`. However, the `slug` field is removed from the `Questionnaire`
model in migration
`0003_remove_questionnaire_qnaire_unique_slug_version_desc_and_more.py`. After
migrations are applied, any attempt to use the search bar in the
`QuestionnaireMembership` admin page will cause Django to query a non-existent field,
raising a `FieldError` and crashing the admin view.

Bug: The new models QuestionnairePermission and QuestionnaireMembership are missing corresponding database migrations, which will cause the application to crash on startup.
Severity: CRITICAL
Suggested Fix
Generate the missing migrations by running python manage.py makemigrations questionnaires. Commit the newly created migration file and include it in the pull request.

Location: backend/questionnaires/models.py#L81-L90
Potential issue: The new models `QuestionnairePermission` and `QuestionnaireMembership`,
along with the `Questionnaire.members` ManyToMany field, have been defined but the
necessary Django database migrations have not been generated. When the application
starts, Django's admin will attempt to register these models, as they are decorated with
`@admin.register`. This will trigger database queries for tables that do not exist,
causing the application to fail on startup with a database error like `OperationalError:
no such table`.
