Closes #71

The frontend SDK exported no session, so a plugin screen had no way to tell an admin from a member and had to offer every control to everyone. The app carried its own copy of the rule in frontend/src/auth/role.ts, which meant a second place for it to drift.

This adds useSession to @alphone/frontend-sdk. It answers the signed-in account as id, email, name and role, or null without a session. A role the SDK cannot read demotes to member, so an unrecognised answer hides a control rather than offering it. roleOf is exported beside it because the graph transport needs the same demotion, and one normaliser has to exist. The testing module gains seedSession alongside the canned adminSession and memberSession.

The app then moves onto that seam so there is exactly one rule. frontend/src/auth/role.ts is deleted, UsersScreen reads one session instead of a session hook plus a role hook, graphTransport takes Role and roleOf from the SDK, and the test harness seeds through the SDK constants instead of its own pair. Behaviour is unchanged and every existing assertion stands untouched, which is the point: the member tests and users-member.spec.ts pass without edits.

Hiding a control stays presentation only. The graph is still the authority and refuses the three admin operations whichever buttons a screen drew.

Testing

  1. Run `make seed` then `make dev`, and sign in at http://localhost:8080 as `admin@example.com` with `password1234`.
  2. Go to Users. As an admin you see the New user action and a Disable and Promote or Demote pair on every row except your own.
  3. Create a user. It appears in the list standing as Member.
  4. Open a private window, sign in as that new account, and go to Users. The full account list still renders, and the New user action and every row control are gone.
  5. Back in the admin window, promote that account, then reload the private window. The controls appear.

Step 4 is the regression this cycle guards.
Step 5 confirms the screen follows the tier rather than caching a first answer.

📝 Walkthrough

Walkthrough

The SDK now exports a nullable useSession hook, normalized Role utilities, and shared session fixtures. UsersScreen, authentication transport, tests, and documentation use the shared session API.

Changes

Shared frontend session API

Layer / File(s) Summary
Session contract and normalization
sdk/frontend/session.ts, sdk/frontend/index.ts
Defines Session and Role, normalizes unknown roles to member, maps authentication data, and exports the API.
Session fixtures and validation
sdk/frontend/testing.tsx, sdk/frontend/test/session.test.tsx
Adds admin and member session fixtures and tests signed-in, signed-out, and role-normalization behavior.
Frontend consumer migration
frontend/src/auth/graphTransport.ts, frontend/src/users/UsersScreen.tsx, frontend/src/test/*
Updates frontend consumers and tests to use SDK session and role data.
Session usage documentation
docs/src/content/docs/extending/screens.md
Documents useSession, session fields, role handling, UI visibility, and backend authorization.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🔵 Low · up to a6b88

The PR centralizes session and role access for plugin screens, but the current head still lacks required TSDoc comments on several changed TypeScript functions. This is a bounded merge-readiness issue that should be addressed or explicitly accepted before merge; no concrete runtime, security, or availability impact is indicated.
