Conversation
Reorganize the auth feature into domain/application/infrastructure/presentation layers. Extracted pure session logic into domain/sessionMachine, added domain types (user, tenant, authEvent), moved the OIDC UserManager to infrastructure/authClient, and created an application-level sessionStore that orchestrates events and side-effects (logAuthEvent). Presentation now exposes pages with dedicated hooks: LoginPage/useLoginRedirect and AuthCallbackPage/useAuthCallback; ProtectedRoute, AuthProvider, and useAuth updated to the new layout. Updated routes, index exports, tests and spec docs to match renames. Behavioral intent unchanged (existing tests/CI expected to pass); this is a pure refactor to improve separation-of-concerns.
This adds a single services-service client created from the live auth session via `getAuthCredentials()`. Requests now automatically attach the bearer token and `X-Tenant-Id`, while still failing closed when there is no authenticated session. It also exposes the session credential reader from the auth barrel and adds focused tests covering the wiring and live-session behavior.
Introduce categories feature: adds Category and CategoryListFilter types, categoryRepository (list, getById) using servicesApi with API_VERSION and tenant-header placeholder, and an index re-export. Adds Vitest tests that stub fetch and auth to cover listing (with/without search), getById 404 handling, and error propagation. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
Document the layered API client contract and simplify the services facade to own version injection, response-envelope unwrapping, and ApiResult conversion. This updates tests to validate the new contract, keeps failures as typed ApiResult values instead of throwing, and tightens the shared Result typing.
This change reorganizes the auth module to the FSD model/api/ui layout and consolidates auth types into the model layer. It also removes the generated X-Tenant-Id header from service request typings, leaving tenant injection to the shared API middleware and keeping callers free from tenant plumbing. The refactor updates imports and tests to match the new structure without changing auth behavior.

- Around line 7-8: Update the `/login` and `/callback` route entries to
reference the implemented component paths under `ui/pages/LoginPage/` and
`ui/pages/AuthCallbackPage/` instead of `presentation/pages/...`, leaving the
remaining route behavior unchanged.
In `@apps/admin-frontend/specs/001-oidc-shell-scaffold/data-model.md`:
- Line 73: Update the module references in the authentication documentation:
replace authEvents.ts with model/sessionStore.ts, and reference reduceSession
and isTransientStatus in model/sessionMachine.ts rather than sessionStore.ts.
Preserve the existing FR-015 description and event-shape details.
In `@apps/admin-frontend/src/app/servicesApi.ts`:
- Around line 1-2: Export createApiClient and createServicesFacade from the
shared API barrel at `@/shared/api/index.ts`, then update servicesApi.ts to import
both symbols from `@/shared/api` instead of their direct implementation modules.
In `@apps/admin-frontend/src/features/auth/model/sessionStore.ts`:
- Around line 79-94: The getUser completion handlers in the session
initialization flow must be invalidated when cleanup runs or logout begins,
preventing stale success or failure callbacks from dispatching after the session
resets. Add a generation/token guard shared by both promise paths, advance it
during cleanup and in logout before signoutRedirect, and ensure callbacks verify
the captured generation in addition to isLoggingOut; add deferred-promise tests
covering cleanup and rejected logout.
In
`@apps/admin-frontend/src/features/auth/ui/pages/AuthCallbackPage/AuthCallbackPage.test.tsx`:
- Around line 5-17: Add jest-axe accessibility assertions to the
AuthCallbackPage test states rendered by renderCallback, covering the callback
page UI while preserving the existing navigation checks; if the page
intentionally renders null in any state, explicitly document that exemption in
the relevant test.

domain/application/infrastructure/presentation layering and inward dependencies.
In

move session policy from

and LoginPage from
apps/admin-frontend/src/features/auth/ui/pages/LoginPage/LoginPage.tsx#L3-L4 to

ProblemDetails fields, including ensuring errors is a record whose field values

and issue arrays, and add a regression test covering a non-array errors field
value while preserving normal valid-payload mapping.

Invalidate stale getUser() completions.
When the cleanup runs or logout() starts, invalidate the pending authClient.getUser() callbacks. The cleanup only removes event listeners. If signoutRedirect() rejects, USER_UNLOADED restores INITIAL_SNAPSHOT; a pending getUser() callback then sees isLoggingOut === false and can dispatch INITIAL_USER, restoring the authenticated session after logout. Guard both completion paths with a generation and add deferred-promise tests for cleanup and failed logout.

Not applied here. This race predates the PR — the sessionStore logic is unchanged; only the file moved (application/ → model/). A generation-token guard + deferred-promise tests is a behavioral change, out of scope for a no-behavior-change restructure. Worth a separate issue.

@evertonschuster, understood. The stale getUser() completion race predates this file move and is outside this no-behavior-change restructure.

Test this infrastructure adapter at the HTTP boundary.
The servicesApi mock bypasses HTTP behavior. These tests cannot validate the request path, query shape, response envelope, or failure mapping.
Replace this mock with MSW handlers for each request. Keep onUnhandledRequest: 'error' enabled.
As per coding guidelines, “Infrastructure tests must use MSW at the HTTP boundary; every request needs a handler and onUnhandledRequest: 'error' must remain enabled.”

Not applied. The categories module is deliberately deferred (to be rebuilt later); the HTTP boundary is already covered by servicesFacade.test.ts, so this test intentionally verifies only mapping/forwarding. Flagged to the maintainer.

@evertonschuster, understood. The current tests cover category mapping and result forwarding. servicesFacade.test.ts covers the shared HTTP boundary.
The MSW requirement still applies when the categories module is rebuilt. Would you like me to open a follow-up GitHub issue for that work?

Restore the category feature dependency direction.
categoryRepository in infrastructure/ imports the application composition root on Line 4. It also declares Category in infrastructure. This makes the feature depend outward and places its domain model in an adapter.
Move Category and its filter to categories/domain. Depend on a feature-local API port or injected ServicesApi. Compose that dependency from app/ instead of importing @/app/servicesApi from the repository.
As per coding guidelines, “Keep each app/service's Domain -> Application -> Infrastructure/Presentation dependency boundaries intact.”

@evertonschuster, thanks for the clarification.
The current @/app/servicesApi import matches the documented wiring. The deferred categories structure still conflicts with the dependency-boundary guideline, so this finding remains open until a follow-up restructures the module.
Would you like me to create a GitHub issue for that follow-up?

Learning: In the `apps/admin-frontend` codebase, follow the established exception-and-catch convention for domain validation and HTTP outcomes: (1) domain factories should throw named `DomainError` subclasses for domain-validation failures, (2) `AuthenticatedHttpClient` should surface non-2xx HTTP outcomes as typed `ApiError` values, and (3) presentation-layer flows should catch/map these errors via `useAsync`, `useCreateInline`, and form submit error-mapping. Do not apply the backend-only result-pattern policy described in `docs/adr/0014-result-pattern-domain-and-persistence-no-exceptions.md` to this frontend convention.
