Closes #864

What does this PR do?

Adds read-only student lookup endpoints under /v1/students:

  • GET /v1/students/:nmec: public profile ({ nmec, name }). Any signed-in user.
  • GET /v1/students/:nmec/photo: photo URL ({ url }). Any signed-in user. The image is not proxied.
  • GET /v1/students/:nmec/schedule: the student's classes and lesson slots. Allowed for the student themself, ADMIN / SUPERUSER, and any participant, meaning a student enrolled in at least one class of the same course (degree). Otherwise 403.
  • GET /v1/students/:nmec/courses/:courseId/metadata: cached Sigarra fest_id for a student in a course. ADMIN / SUPERUSER only. The role is checked before the lookup, so non-admins get 403 whether or not the student exists.

Behaviour notes:

  • :nmec is normalised, so up202012345 and 202012345 resolve to the same student.
  • An unknown student returns 404 student-not-found (except the metadata route, which returns 403 to non-admins first).
  • courseId must be an integer, otherwise 422 validation-error.

Structure follows the existing clean architecture layering:

  • Domain: StudentRepository, ScheduleRepository and StudentPhotoProvider ports. StudentProfile deliberately omits email and role.
  • Application: one use case per endpoint. Each returns a reason on failure and never throws HTTP errors.
  • Infrastructure: Prisma implementations of the two repositories, and a Sigarra photo URL builder that makes no network call.
  • Interface: students.routes.ts maps use-case reasons to HttpErrors in one place. students.schemas.ts holds the response schemas, which also feed the OpenAPI doc.

Other changes:

  • createApp accepts an optional studentPhotos dependency, defaulting to the Sigarra adapter.
  • ApiRoutesDeps now includes the student repositories and photo provider.
  • docs/endpoints.md documents the new routes, their access rules, and response shapes.
  • The OpenAPI test lists the four new routes with their tags and summaries.

No schema or migration changes.

How to test

From apps/backend:

bun run test
bun run typecheck

The new route tests (tests/interface/routes/students.routes.test.ts) drive createApp().handle(...) with fake repositories, so no database is required. They cover:

  • 401 for anonymous callers on every route.
  • Profile visibility for any signed-in user, including up-prefixed NMECs.
  • Schedule access for owner, same-course participant, admin, superuser, and stranger (403).
  • Metadata access, including that a non-admin gets 403 for unknown students too.
  • 404 vs 422 error bodies.

The use-case test (tests/application/use-cases/students/get-student-schedule.test.ts) checks that the shared-course query only runs when the cheaper checks don't already decide access.

To check against a real database, start Postgres, seed the demo data, and call the endpoints with a session for a user enrolled in a class (e.g. GET /v1/students/<nmec>/schedule). Expect the same status codes listed above.

Screenshots

N/A. Backend only, no UI changes.

Summary by CodeRabbit

  • New Features
    • Added student endpoints for retrieving profiles, photo URLs, class schedules, and course metadata.
    • Students, administrators, and superusers can view schedules; other enrolled students can view schedules when they share a course.
    • Course metadata is restricted to administrators. Student numbers with an up prefix are accepted.
    • Responses distinguish missing students, unavailable course metadata, and denied access.

- Add /v1/students/:nmec profile, photo, schedule and course metadata routes
- Profile and photo URL are readable by any signed-in user; profile exposes name only
- Schedule is visible to the owner, admins, and students sharing a course
- Course metadata is admin-only and checked before lookup, so non-admins get 403 regardless of whether the student exists
- Normalise the NMEC so the `up`-prefixed form resolves to the same student
- Document the endpoints in endpoints.md and cover the policy with tests

📝 Walkthrough

This change adds four authenticated student lookup endpoints for profiles, photo URLs, schedules, and course metadata. It adds repository contracts and implementations, applies endpoint access rules, wires the routes into the API, and adds tests and endpoint documentation.

Changes: Student lookup

Layer / File(s) Summary
Student data contracts and repositories
apps/backend/src/domain/ports/student.repository.ts, apps/backend/src/domain/ports/schedule.repository.ts, apps/backend/src/infrastructure/database/repositories/*
Adds student and schedule data contracts, Prisma-backed lookups, and repository factory registration. The schedule repository returns sorted schedule data and checks whether students share a course.
Lookup results and access rules
apps/backend/src/application/use-cases/students/*, apps/backend/src/domain/ports/student-photo.provider.ts, apps/backend/src/infrastructure/external/sigarra-student-photo.ts, apps/backend/tests/application/use-cases/students/*
Adds profile, photo, schedule, and course-metadata use cases. Schedule access allows the student, admins, superusers, and participants who share a course. Course metadata access checks the caller’s admin role before looking up the student.
Student API routes and validation
apps/backend/src/interface/routes/students/*, apps/backend/src/interface/routes/api.routes.ts, apps/backend/src/main.ts, apps/backend/tests/interface/routes/students.routes.test.ts, apps/backend/tests/interface/plugins/openapi.test.ts, apps/backend/docs/endpoints.md
Registers the four authenticated routes, defines request and response schemas, wires the photo provider, and documents the endpoints. Tests cover authentication, access rules, missing records, NMEC normalization, and invalid course IDs.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to b5b59

The new student lookup endpoints look sound, but the endpoint table in the docs still shows ? for who can access the profile and photo routes and omits that students can read their own schedule. Update the table so the docs match the implemented access rules; this is low risk.

Explanation

The description includes the required issue reference, change summary, testing instructions, and screenshots section. It also documents endpoint behavior, access rules, architecture changes, and test coverage.

Full details: Out of Scope Changes check

Explanation

The reviewed changes stay within issue #864. Domain ports, use cases, Prisma adapters, route wiring, schemas, documentation, OpenAPI coverage, and fake-repository HTTP tests directly support the four student lookup endpoints and their access rules. No unrelated feature, schema change, or migration is shown.

Full details: Linked Issues check

Explanation

Issue #864 requires 404 when the student does not exist and 403 when the caller lacks permission. The implementation checks the caller role before the student lookup on the metadata route. Therefore, a non-admin request for an unknown student returns 403, not the required 404. The route tests explicitly assert this behavior. The other #864 objectives are implemented: authenticated profile and photo routes, schedule access for the owner, same-course users, ADMIN, and SUPERUSER, admin metadata access, validation, and HTTP integration tests.

Resolution

Change the metadata access flow to return 404 for an unknown student before applying the non-admin permission result. Retain 403 for non-admin callers when the student exists. Update the metadata route tests and documentation to match issue #864.

Full details: Docstring Coverage

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 12 functions across 18 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Fill in the Auth column for the routes this PR adds.

Line 315 changes the profile row's Auth value from admin to ?. In this table, ? marks an access rule that has not been decided yet. This PR does decide the rule: studentRoutes requires a session for every route. The new section also says profile and photo lookups are open to any signed-in user. As a result, the table and the new section now disagree.

The photo row (Line 317) has the same ? value, but its route is also implemented in this PR. The schedule row (Line 316) lists admin / participant, but getStudentSchedule also lets the student read their own schedule. AGENTS.md calls this file "the single source of truth for API documentation", so the table must match the implemented routes.
