## Current Development State

**Phase 1 (Foundation):** Complete — project scaffold, Docker infra, Prisma schema (all domains), Epicor connection, Better Auth, middleware, permissions, company selector.

**Phase 2 (Core Features):** In progress
- Dashboard: implemented (summary cards, quick nav, recent orders/shipments tables)
- Inventory: implemented (all 6 category summaries + detail drill-down)
- Orders: implemented (list page with search and CSV export, HDC exception)
- Remaining: shipments, coil-activity, invoices, shipment-requests, allocation-requests, jobs, admin pages

**Dev workflow:** Local Next.js dev server with hot reload via `PORT=3001 npm run dev`. Traefik routes `dev.quest.vorteq.wulf.cloud` to host:3001 via `traefik/config/dev-local.yml`. The `app-dev` Docker container should be stopped during local dev to avoid route conflicts.

**Auth status:** Better Auth is configured with Prisma adapter. A custom login endpoint exists at `/api/auth/login`. Auth middleware is temporarily disabled in dev mode (`DEV_MODE=true` bypasses to a mock admin session). The dev domain (`dev.quest.vorteq.wulf.cloud`) also bypasses auth in middleware.

**Git:** Currently only `main` branch. No `development` branch yet.

## Coding Conventions

### General
- TypeScript strict mode, no `any` types
- Use `type` over `interface` unless extending
- Prefer `const` over `let`, never `var`
- Use named exports, not default exports (except page.tsx and layout.tsx)
- Error handling: use typed error classes, not string throws
- All API responses: `{ data: T }` on success, `{ error: string, code: string }` on failure

### Naming
- Files: kebab-case (`shipment-requests.ts`)
- Components: PascalCase (`ShipmentRequestForm.tsx`)
- Functions/variables: camelCase
- Database columns (Prisma): snake_case
- API routes: kebab-case (`/api/shipment-requests`)
- Environment variables: SCREAMING_SNAKE_CASE

### Formatting (Prettier)
- Single quotes, semicolons, trailing commas (es5)
- 2-space indentation, 80 char print width
- Tailwind class sorting via `prettier-plugin-tailwindcss`

### Database
- Prisma schema uses snake_case for all fields
- Map legacy PascalCase column names with `@map("LegacyName")` where needed
- Always use parameterized queries for Epicor MSSQL — never string interpolation
- Epicor queries go in `src/services/` with typed return values
- PostgreSQL queries go through Prisma client exclusively

### Component Pattern
```typescript
// Server component by default
export async function InventorySummary({ category }: { category: string }) {
  const data = await getInventorySummary(category);
  return <DataTable columns={columns} data={data} />;
}

// Client component only when interactivity needed
'use client';
export function ShipmentRequestCart() { ... }
```

## Epicor Connection Patterns

### Connection (`src/lib/epicor.ts`)
- Singleton connection pool via `mssql` package
- Typed error classes: `EpicorConnectionError`, `EpicorQueryError`, `EpicorTimeoutError`
- `execStoredProc<T>(name, params)` — execute stored procedure, returns `T`
- `execQuery<T>(query, params)` — execute parameterized SQL, returns `T`
- `execPortalStoredProc<T>(name, custId, dbName, sub, additionalParams)` — convenience wrapper with standard portal params
- `getPortalDbName()` — returns `[VorteqPortal]` (bracketed DB name for cross-DB SP parameter)
- `checkConnection()` — health check
- Graceful shutdown on SIGINT/SIGTERM

### Inventory Stored Procedure Parameters

**V6 procedures** (WIP, Finished Goods, Processed Other):
- `@Customer` — the selected company's EpicorCustID
- `@DBNAME` — portal database name in brackets, e.g., `[VorteqPortal]`
- `@SUBUSER` — 0 or 1 (sub-user flag)
- Detail variants also accept `@PART`, `@PLANT`, `@WAREHOUSE` for filtering

**Non-V6 procedures** (Unprocessed, R&R variants):
- `@CUSTID` — the selected company's EpicorCustID
- `@DBNAME` — portal database name in brackets
- No sub-user parameter — sub-users are blocked entirely (return empty array)
- Detail variants accept `@part`, `@plant`, `@warehouse` (lowercase)

### Orders Pattern
- Uses `execQuery` with parameterized SQL against Epicor views
- Standard view: `dbo.portal_Orders WHERE CustomerID = @CustID`
- HDC exception: uses `dbo.portal_OrdersHDC` view and maps CustID `HDC` → `HDM`

### Column Mapping
Epicor SP results use PascalCase column names. Services map them to snake_case:
```typescript
function mapSummaryRow(raw: Record<string, unknown>): InventorySummaryRow {
  return {
    part_num: String(raw.VorteqPartNum ?? ''),
    description: String(raw.VorteqPartDesc ?? ''),
    on_hand_qty: Number(raw.OnHandQty ?? 0),
    // ...
  };
}
```

## Auth & Session Pattern

### Better Auth (`src/lib/auth.ts`)
- Prisma adapter connecting to `auth_user`, `auth_session`, `auth_account` tables
- Email + password enabled, email verification disabled
- 7-day session expiry

### Quest Session (`src/lib/permissions.ts`)
`getQuestSession()` enriches the Better Auth session with:
- `questUserId` — from `quest_user` table
- `activeCompanyId` — from cookie-based session store (`src/lib/session.ts`)
- `isSubUser` — from `quest_user.is_sub_user`
- `permissionRules[]` — collected from user type → permission groups → permission rules
- `userType` — e.g., "Admin", "Super Admin", "Customer User"

In dev mode (`DEV_MODE=true`), returns a mock admin session with all permissions.

### Permission Helpers (`src/lib/permissions.ts`)
- `requirePermission(rule)` — throws if user lacks permission
- `hasPermission(rule)` — returns boolean
- `isAdmin()` / `requireAdmin()` — check for Admin or Super Admin user type
- `isSubUser()` — check sub-user status
- `requireActiveCompany()` — throws if no company selected
- `getActiveCompany()` — returns the active `quest_company` record
- `getUserCompanies()` — returns accessible companies (admins see all active)
- `PermissionRules` — constant object with all permission rule names

## Important Business Logic

### Company Context
After login, the user's active company is stored in a cookie (`quest_session`). All Epicor queries are scoped to that company's `EpicorCustID`. Admin users can switch companies and see all active companies.

### Sub-User Restrictions
Users with `is_sub_user=true` on their `quest_user` record:
- See filtered inventory data (SUBUSER=1 parameter to V6 stored procedures)
- See filtered ship-to addresses (only those matching '%NB HANDY%')
- Cannot access Unprocessed inventory or R&R data at all

### HDC/HDM Customer Exception
Customer 'HDC' uses a special order view (`portal_OrdersHDC`) and maps to CustID 'HDM' in queries. Handled in `src/services/orders.ts`.

### VGL Customer Exception
Customer 'VGL' uses a special SQL query for coil receipts instead of the standard view.

## Commands

```bash
# Development
npm run dev              # Start Next.js dev server
npm run build            # Production build
npm run start            # Start production server
npm run lint             # ESLint
npm run typecheck        # TypeScript type checking (tsc --noEmit)
npm test                 # Vitest
npm run test:e2e         # Playwright E2E tests

# Database
npx prisma migrate dev   # Create + apply migration (dev)
npx prisma migrate deploy # Apply migrations (prod)
npx prisma db push       # Push schema without migration
npx prisma generate      # Regenerate Prisma client
npx prisma studio        # Database GUI
tsx prisma/seed.ts       # Run seed script

# Docker
docker compose up -d     # Start all services
docker compose ps        # Check service status
docker compose logs -f vorteq-dev  # Tail dev container logs

# Pre-commit checks
npm run lint && npm run typecheck && npm test
```

### Local Development (Hot Reload)
```bash
# Start local dev (instead of Docker container)
docker compose stop app-dev              # Release the competing Traefik route
PORT=3001 npm run dev                    # Run in a tmux pane — hot reload at https://dev.quest.vorteq.wulf.cloud

# Stop local dev (restore containerized version)
# Ctrl+C the dev server, then:
docker compose start app-dev
```
Traefik routes `dev.quest.vorteq.wulf.cloud` → `http://172.17.0.1:3001` via `traefik/config/dev-local.yml`. CI/CD pipeline is unchanged — pushes to `main` still build and deploy the production container.

## Testing Requirements

- Unit tests for all service functions (inventory, orders, shipments data transformations)
- Integration tests for API routes with mocked DB connections
- E2E tests for: login flow, inventory browse + drill-down, shipment request workflow, invoice upload
- Data validation: compare Epicor query results with known-good outputs from the legacy system

## Git Workflow

- `main` branch: production-ready code → deploys to `quest.vorteq.wulf.cloud`
- `development` branch: integration branch → deploys to `dev.quest.vorteq.wulf.cloud` (not yet created)
- Feature branches: `feature/F-001-project-scaffold`
- Commit messages: `feat(F-001): scaffold Next.js project with TypeScript + Tailwind`
- Run `npm run lint && npm run typecheck && npm test` before committing
- Push triggers Forgejo Actions → Docker build → registry push → deploy

## Task Tracking

All tasks are tracked in `TASKS.md`. Mark tasks as:
- `[ ]` Not started
- `[~]` In progress
- `[x]` Complete
- `[!]` Blocked (note blocker in comments)
