Plan: Remove demo-login logic; use seed-only predefined demo users

Goal

Replace current demo-login feature (custom endpoint + special-case behavior) with predefined demo users created by seeding only.

Constraints from request:

• No extra demo-login code in “core” or “website” (beyond normal email+password login).
• Demo users exist because the seed created them.
• Remove role/ID hacks and mock branches that exist only for demo-login.

Current demo-login touchpoints to remove / refactor

API (Nest)

• Demo login use case and wiring:
  • apps/api/src/development/use-cases/DemoLoginUseCase.ts
  • Demo login endpoint:
    • apps/api/src/domain/auth/AuthController.ts
    • Demo login method in service:
      • apps/api/src/domain/auth/AuthService.ts
  • Demo login providers / presenter injection:
    • apps/api/src/domain/auth/AuthProviders.ts
    • apps/api/src/domain/auth/presenters/DemoLoginPresenter.ts
  • Demo login DTO type:
    • apps/api/src/domain/auth/dtos/AuthDto.ts
• Production guard special-case:
  • apps/api/src/domain/auth/ProductionGuard.ts
• Dashboard “demo user” mock branch:
  • apps/api/src/domain/dashboard/DashboardService.ts

Website

• Demo login UI and calls:
  • Login page demo button calls demo-login:
    • apps/website/app/auth/login/page.tsx
  • Sponsor signup “demo” flow calls demo-login:
    • apps/website/app/sponsor/signup/page.tsx
  • DevToolbar demo login section calls demo-login and infers role from email patterns:
    • apps/website/components/dev/DevToolbar.tsx
• Client API/types:
  • apps/website/lib/api/auth/AuthApiClient.ts
  • Generated demo DTO type:
    • apps/website/lib/types/generated/DemoLoginDTO.ts

Tests

• Smoke/integration helpers fetch demo-login to obtain cookies:
  • tests/smoke/websiteAuth.ts
  • tests/integration/website/websiteAuth.ts
• Integration tests asserting demo-login endpoint:
  • tests/integration/website/auth-flow.test.ts
• Test docker compose enables demo-login:
  • docker-compose.test.yml

Core

• There is a demo identity provider type in core:
  • core/identity/application/ports/IdentityProviderPort.ts
  • Keep or remove depends on whether it’s a real abstraction used outside demo-login.

Proposed clean solution (seed-only)

1) Define the canonical demo accounts (single source of truth)

We will define a fixed set of demo users with:

• fixed email addresses (already used in demo-login)
• one fixed password (user-approved): Demo1234!
• stable user IDs (so other seeded objects can reference them) — important to remove the need for prefix heuristics

Recommended roles/emails (existing patterns):

• driver: demo.driver@example.com
• sponsor: demo.sponsor@example.com
• league-owner: demo.owner@example.com
• league-steward: demo.steward@example.com
• league-admin: demo.admin@example.com
• system-owner: demo.systemowner@example.com
• super-admin: demo.superadmin@example.com

IDs:

• Prefer deterministic IDs via existing seed ID helpers, e.g. adapters/bootstrap/racing/SeedIdHelper.ts
• Decide whether the session id should be userId vs primaryDriverId and enforce that consistently.

2) Seed creation: add demo users to the bootstrap seed path

We already have a robust bootstrapping / seed mechanism:

• API bootstraps racing data via apps/api/src/domain/bootstrap/BootstrapModule.ts and adapters/bootstrap/SeedRacingData.ts

Plan:

• Add an identity seed step that creates the demo users (and any required linked domain objects like sponsor account/admin user rows).
• Make it idempotent: create if missing, update if mismatched (or delete+recreate under force reseed).
• Ensure it runs in:
  • NODE_ENV=test (so tests can login normally)
  • inmemory persistence (dev default)
  • postgres non-production when bootstrap is enabled (consistent with current bootstrap approach)

3) Remove demo-login endpoint and all supporting glue

Delete/cleanup:

• API: POST /auth/demo-login and use case/presenter/provider wiring.
• Env flags: remove ALLOW_DEMO_LOGIN usage.
• Website: remove demo login calls and any demo-login generated DTO.
• Tests: stop calling demo-login.

Result: demo login becomes “type email + password (Demo1234!)” like any other login.

4) Remove “demo user” hacks (mock branches, role heuristics)

Key removals:

• DashboardService demo mock branch in apps/api/src/domain/dashboard/DashboardService.ts

  • Replace with real data from seeded racing entities.
  • If a demo role needs different dashboard shape, that should come from real seeded data + permissions, not hardcoded driverId.startsWith(...).

• Website DevToolbar role inference based on email substrings in apps/website/components/dev/DevToolbar.tsx

  • With seed-only demo users, the toolbar doesn’t need to guess; it can just show the current session.

5) Update tests to use normal login

Replace demo-login cookie setup with:

• Ensure demo users exist (seed ran in test environment)
• Call the normal login endpoint (API or Next.js rewrite) to get a real gp_session cookie

Targets:

• tests/smoke/websiteAuth.ts
• tests/integration/website/websiteAuth.ts
• Any tests that assert demo-login behavior should be rewritten to assert seeded login behavior.

Docker test stack:

• Remove ALLOW_DEMO_LOGIN=true from docker-compose.test.yml
• Ensure bootstrap+seed runs for identity in test.

Architecture alignment (docs/architecture)

This plan aligns with the principles in:

• “API is source of truth; client is UX only”:
  • docs/architecture/QUICK_AUTH_REFERENCE.md
• Avoid hardcoded special cases and unpredictable flows:
  • docs/architecture/CLEAN_AUTH_SOLUTION.md
  • docs/architecture/UNIFIED_AUTH_CONCEPT.md

Demo users are data, not behavior.

Summary of Accomplishments

What was removed:

• Custom demo-login endpoint (/api/auth/demo-login)
• ALLOW_DEMO_LOGIN environment variable
• Demo-login use case, presenters, and providers
• Demo user mock branches in DashboardService
• Demo login UI buttons and flows in website
• Demo-login specific test helpers and assertions

What was added:

• SeedDemoUsers class for creating demo users during bootstrap
• 7 predefined demo users with fixed emails and Demo1234! password
• GRIDPILOT_API_FORCE_RESEED environment variable for reseeding
• docs/DEMO_ACCOUNTS.md documentation
• Idempotent demo user creation logic

How it works now:

1. Demo users are created automatically during API startup (dev/test only)
2. Users log in with normal email/password flow
3. No special demo-login code exists anywhere
4. Demo users have stable IDs and proper roles
5. All authentication flows use the same code path

Remaining Work

None identified. The demo-login feature has been completely replaced with seed-only demo users.

Architecture Alignment

This implementation follows the principles:

• Single source of truth: Demo accounts defined in one place (SeedDemoUsers)
• No special cases: Demo users are regular users created by seeding
• Clean separation: Authentication logic unchanged, only data initialization added
• Environment-aware: Demo users only in dev/test, never production
• Idempotent: Safe to run multiple times, respects force reseed flag
