+# Demo Accounts
+
+This document serves as the single source of truth for demo accounts in the GridPilot application.
+
+## Overview
+
+Demo accounts are predefined user accounts created during application bootstrap for testing and development purposes. They use a fixed password and are automatically seeded into the system.
+
+## Available Demo Accounts
+
+All demo accounts use the same fixed password: **`Demo1234!`**
+
+| Email | Role | Display Name | Notes |
+|-------|------|--------------|-------|
+| `demo.driver@example.com` | user | John Driver | Standard user account with primary driver ID |
+| `demo.sponsor@example.com` | user | Jane Sponsor | Standard user account |
+| `demo.owner@example.com` | owner | Alice Owner | League owner account with admin privileges |
+| `demo.steward@example.com` | user | Bob Steward | User account with admin privileges |
+| `demo.admin@example.com` | admin | Charlie Admin | Administrator account |
+| `demo.systemowner@example.com` | admin | Diana SystemOwner | Administrator account |
+| `demo.superadmin@example.com` | admin | Edward SuperAdmin | Administrator account |
+
+## How Demo Users Are Created
+
+Demo users are created automatically during application startup through the bootstrap process:
+
+1. **Bootstrap Module**: The `BootstrapModule` runs on API startup
+2. **SeedDemoUsers**: This class creates/updates demo users with fixed specifications
+3. **Idempotent**: If demo users already exist, they are only updated if force reseed is enabled
+4. **Environment-aware**: Demo users are only created in development and test environments (never in production)
+
+### Creation Process
+
+- Users are created with deterministic IDs based on their email addresses
+- Passwords are hashed using the password hashing service
+- Admin users also get corresponding `AdminUser` entities with appropriate roles
+- Users needing primary driver IDs get them generated based on their email
+
+## Environment Variables
+
+### `GRIDPILOT_API_BOOTSTRAP`
+- **Purpose**: Controls whether bootstrap seeding runs on startup
+- **Default**: `true` (enabled by default)
+- **Values**: 
+  - `true`, `1`, or any truthy value = enabled
+  - `false`, `0` = disabled
+- **Usage**: Set to `false` to skip all seeding (including demo users)
+
+### `GRIDPILOT_API_FORCE_RESEED`
+- **Purpose**: Forces reseeding of demo users even if they already exist
+- **Default**: `false` (disabled)
+- **Values**:
+  - `true`, `1`, or any truthy value = enabled
+  - `false`, `0` or unset = disabled
+- **Usage**: Set to `true` to update existing demo users with new data
+
+### `GRIDPILOT_API_PERSISTENCE`
+- **Purpose**: Controls database persistence type
+- **Values**: `postgres` or `inmemory`
+- **Impact**: Demo users work with both persistence types
+
+### `NODE_ENV`
+- **Purpose**: Environment mode
+- **Impact**: Demo users are only seeded in `development` and `test` environments, never in `production`
+
+## How to Use Demo Accounts
+
+### Login
+Use the standard login API endpoint with any demo email and the password `Demo1234!`:
+
+```bash
+# Example login request
+POST /api/auth/login
+{
+  "email": "demo.driver@example.com",
+  "password": "Demo1234!"
+}
+```
+
+### Access Demo Accounts
+1. Start the application in development or test mode
+2. Bootstrap will automatically create/update demo users
+3. Use any demo email and password `Demo1234!` to log in
+4. Different accounts have different roles and permissions for testing
+
+## Forcing Reseed of Demo Users
+
+To force reseeding of demo users (updates existing users):
+
+### Option 1: Environment Variable
+```bash
+GRIDPILOT_API_FORCE_RESEED=true npm run dev
+```
+
+### Option 2: Docker Compose
+Add to your `.env` file or docker-compose override:
+```yaml
+environment:
+  - GRIDPILOT_API_FORCE_RESEED=true
+```
+
+### Option 3: Test Environment
+Demo users are automatically reseeded in test environments when needed.
+
+## Demo User Specifications
+
+Each demo user is defined with these properties:
+- **email**: Fixed email address
+- **password**: Always `Demo1234!`
+- **needsAdminUser**: Whether to create an AdminUser entity
+- **needsPrimaryDriverId**: Whether to generate a primary driver ID
+- **roles**: Array of roles for admin users
+- **displayName**: Human-readable name
+
+## Security Considerations
+
+- Demo accounts should only be used in development and testing
+- Never enable demo accounts in production
+- The fixed password is acceptable for demo purposes but should never be used for real accounts
+- Demo users have predictable emails, making them unsuitable for security testing
+
+## Troubleshooting
+
+### Demo Users Not Created
+1. Check `NODE_ENV` is not `production`
+2. Verify `GRIDPILOT_API_BOOTSTRAP` is not set to `false`
+3. Check logs for bootstrap errors
+4. Ensure database connection is working (for postgres persistence)
+
+### Demo Users Not Updating
+1. Set `GRIDPILOT_API_FORCE_RESEED=true` to force updates
+2. Check that bootstrap is running on startup
+3. Verify the SeedDemoUsers class is being called
+
+### Want to Skip Demo Users
+Set `GRIDPILOT_API_BOOTSTRAP=false` to skip all seeding, or modify the bootstrap logic to exclude demo user seeding specifically.

+# 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`](apps/api/src/development/use-cases/DemoLoginUseCase.ts)
+  * Demo login endpoint:
+    * [`apps/api/src/domain/auth/AuthController.ts`](apps/api/src/domain/auth/AuthController.ts)
+    * Demo login method in service:
+      * [`apps/api/src/domain/auth/AuthService.ts`](apps/api/src/domain/auth/AuthService.ts)
+  * Demo login providers / presenter injection:
+    * [`apps/api/src/domain/auth/AuthProviders.ts`](apps/api/src/domain/auth/AuthProviders.ts)
+    * [`apps/api/src/domain/auth/presenters/DemoLoginPresenter.ts`](apps/api/src/domain/auth/presenters/DemoLoginPresenter.ts)
+  * Demo login DTO type:
+    * [`apps/api/src/domain/auth/dtos/AuthDto.ts`](apps/api/src/domain/auth/dtos/AuthDto.ts)
+* Production guard special-case:
+  * [`apps/api/src/domain/auth/ProductionGuard.ts`](apps/api/src/domain/auth/ProductionGuard.ts)
+* Dashboard “demo user” mock branch:
+  * [`apps/api/src/domain/dashboard/DashboardService.ts`](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`](apps/website/app/auth/login/page.tsx)
+  * Sponsor signup “demo” flow calls demo-login:
+    * [`apps/website/app/sponsor/signup/page.tsx`](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`](apps/website/components/dev/DevToolbar.tsx)
+* Client API/types:
+  * [`apps/website/lib/api/auth/AuthApiClient.ts`](apps/website/lib/api/auth/AuthApiClient.ts)
+  * Generated demo DTO type:
+    * [`apps/website/lib/types/generated/DemoLoginDTO.ts`](apps/website/lib/types/generated/DemoLoginDTO.ts)
+
+### Tests
+
+* Smoke/integration helpers fetch demo-login to obtain cookies:
+  * [`tests/smoke/websiteAuth.ts`](tests/smoke/websiteAuth.ts)
+  * [`tests/integration/website/websiteAuth.ts`](tests/integration/website/websiteAuth.ts)
+* Integration tests asserting demo-login endpoint:
+  * [`tests/integration/website/auth-flow.test.ts`](tests/integration/website/auth-flow.test.ts)
+* Test docker compose enables demo-login:
+  * [`docker-compose.test.yml`](docker-compose.test.yml)
+
+### Core
+
+* There is a demo identity provider type in core:
+  * [`core/identity/application/ports/IdentityProviderPort.ts`](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`](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`](apps/api/src/domain/bootstrap/BootstrapModule.ts) and [`adapters/bootstrap/SeedRacingData.ts`](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`](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`](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/smoke/websiteAuth.ts)
+* [`tests/integration/website/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`](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`](docs/architecture/QUICK_AUTH_REFERENCE.md)
+* Avoid hardcoded special cases and unpredictable flows:
+  * [`docs/architecture/CLEAN_AUTH_SOLUTION.md`](docs/architecture/CLEAN_AUTH_SOLUTION.md)
+  * [`docs/architecture/UNIFIED_AUTH_CONCEPT.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
+
+### Files Created
+
+- `docs/DEMO_ACCOUNTS.md` - Complete documentation for demo accounts
+
+### Files Modified
+
+- `adapters/bootstrap/SeedDemoUsers.ts` - Demo user seed implementation
+- `apps/api/src/domain/bootstrap/BootstrapModule.ts` - Integrated demo user seeding
+- `apps/api/src/domain/bootstrap/BootstrapProviders.ts` - Added demo user seed provider
+- `tests/smoke/websiteAuth.ts` - Updated to use seeded login
+- `tests/integration/website/websiteAuth.ts` - Updated to use seeded login
+- `tests/integration/website/auth-flow.test.ts` - Updated to test seeded login
+- `docker-compose.test.yml` - Removed ALLOW_DEMO_LOGIN
+- `plans/2026-01-03_demo-users-seed-only-plan.md` - This document updated
+
+### Environment Variables
+
+**New:**
+- `GRIDPILOT_API_FORCE_RESEED` - Force reseed demo users
+
+**Removed:**
+- `ALLOW_DEMO_LOGIN` - No longer needed
+
+**Existing (unchanged):**
+- `GRIDPILOT_API_BOOTSTRAP` - Controls all seeding
+- `GRIDPILOT_API_PERSISTENCE` - Database type
+- `NODE_ENV` - Environment mode
+
+### Demo Users Available
