# Safety Quiz Results Backend

## Purpose

`safety_quiz_results` stores weekly safety/de-escalation quiz submissions per authenticated staff
user. The backend owns tenant scope, user ownership, the user display-name snapshot, the product
role snapshot, and persistence. Each submission is an append (create) — there is no update path.

## Slice Files (by layer)

- Route: `src/routes/safety_quiz_results.ts` (thin wiring; `GET /`, `POST /`).
- Controller: `src/api/controllers/safety_quiz_results.controller.ts` (custom — not the CRUD
  factory).
- Service (BLL): `src/services/safety_quiz_results.ts`.
- Repository (DAL): queries run through `db.safety_quiz_results` inside the service (no separate
  `db/api/safety_quiz_results.ts`).
- Model: `src/db/models/safety_quiz_results.ts`.
- Shared used: `db/with-transaction.ts` (`withTransaction`); `shared/constants/pagination.ts`
  (`resolvePagination`); `services/shared/access.ts` (`getOrganizationIdOrGlobal`, `getCampusId`,
  `assertAuthenticatedTenantUser`, `hasFeaturePermission`, `getDisplayName`);
  `shared/constants/roles.ts` (`ROLE_NAMES`); `shared/errors/validation.ts` (`ValidationError`).

## API

All routes require JWT authentication. Base path mounted at `/api/safety_quiz_results`.

- `GET /api/safety_quiz_results` -> `200` `{ rows, count }`. Optional query `week_of`, plus
  `limit` / `page` (paginated via `resolvePagination`). Returns results visible to the current user
  (see Access Rules), ordered by `completed_at` desc.
- `POST /api/safety_quiz_results` -> `201`. Request body wrapped as `{ data: <SafetyQuizInput> }`.
  Returns the created result DTO. If the caller is a parent-scope user acting through a drilled
  child scope, the request is accepted as a no-op and returns `null`.

## Access Rules

- All operations require an authenticated tenant user (`assertAuthenticatedTenantUser`).
- `create`: a staff user creates a result for themselves; ownership fields are filled from the
  authenticated user.
- `create` persists only when the active scope is the user's own scope. Parent users drilled into a
  child school/campus/classroom can complete the quiz there, but the backend does not create
  reportable quiz rows for that child scope.
- `list`: users with `READ_SAFETY_QUIZ_REPORTS` see scope-filtered results;
  everyone else sees only their own rows (filtered by `userId`).
  Role-seeded permissions are only the baseline grants. `custom_permissions` can
  grant the report permission and
  `custom_permissions_filter` can remove it for non-global users.

## Tenant Scope

- Organization is resolved via `getOrganizationIdOrGlobal`: global access users bypass the org
  filter and see results across all organizations; regular users are bound to their organization.
- On create, `campusId` is set from `getCampusId`; `userId`, `createdById`, `updatedById` come from
  the current user.
- Drilled child scopes are not treated as the user's own scope for personal saves, even though list
  visibility can use the active scope for reports.

## Data Contract

- Mutation input (`SafetyQuizInput`): `quiz_id`, `quiz_title`, `week_of` (non-empty strings);
  `score` and `total_questions` (integers); `answers` (an array of integers). Invalid input raises
  `ValidationError`.
- On create the backend fills `user_name` from `getDisplayName(currentUser)` and `user_role` from
  the user's `app_role.name` (defaulting to `teacher`); `completed_at` is set to the current time. The frontend does not
  send name, role, or ownership fields.
- DTO fields: `id`, `quiz_id`, `quiz_title`, `week_of`, `score`, `total_questions`, `answers`,
  `user_name`, `user_role`, `completed_at`, `organizationId`, `campusId`, `userId`, `createdAt`,
  `updatedAt`.
- Model columns: `quiz_id`, `quiz_title`, `week_of`, `user_name`, `user_role` (all TEXT, not null);
  `score`, `total_questions` (INTEGER, not null); `answers` (JSONB, not null); `completed_at`
  (DATE, not null); `importHash` (unique); plus tenant/audit UUID columns (`organizationId`,
  `campusId`, `userId`, `createdById`, `updatedById`, all nullable). The model is `paranoid` (soft
  delete via `deletedAt`) and uses `freezeTableName`.
- Associations: `belongsTo` organizations (`organization`), campuses (`campus`), users (`user`,
  `createdBy`, `updatedBy`).

## Behavior / Notes

- `create` first checks whether the caller is acting in their own scope. If not, it skips
  persistence and returns `null`. Otherwise it runs inside `withTransaction`; trimmed string fields
  are persisted.
- `list` is paginated with shared defaults (`resolvePagination`).

## Tests

- `src/services/personal_scope_results.test.ts` verifies that parent users drilled into child
  scopes do not create safety quiz result rows.
