}

Perfect! Now let me compile a comprehensive exploration report. I have all the necessary information about the architectural patterns.

## Comprehensive Exploration Report

I've systematically examined the **cwc-api**, **cwc-auth**, and **cwc-backend-utils** packages to understand the established architectural patterns. Here's my detailed findings:

---

## 1. CWC-API Current Structure

### File Organization
**Location:** `/Users/jeffbazinet/coding-with-claude/source/coding-with-claude-application/packages/cwc-api/src`

**Current structure:**
```
src/
├── index.ts                    # Express service entry point
├── config/
│   ├── index.ts
│   ├── config.types.ts
│   └── loadConfig.ts
├── context/
│   ├── index.ts
│   ├── context.types.ts       # RequestContext types
│   └── createContext.ts       # JWT verification & context creation
└── __tests__/
    ├── config.test.ts
    ├── healthCheck.test.ts
    ├── context/
    │   └── createContext.test.ts
    └── mocks/
        ├── authClient.mock.ts
        ├── sqlClient.mock.ts
        ├── config.mock.ts
        └── logger.mock.ts
```

### Context Layer (Phase 2 - Complete)
**Location:** `src/context/`

The context layer provides centralized authentication without duplicating JWT verification logic:

1. **context.types.ts** defines:
   ```typescript
   type AuthenticatedContext = {
     isAuthenticated: true;
     role: Exclude<CwcRole, 'guest-user'>;  // 'project-owner' | 'logged-on-user'
     userPkId: number;
     username: string;
     ownedProjects: string[];
     payload: UserJwtPayload;  // Full JWT payload
   };

   type GuestContext = {
     isAuthenticated: false;
     role: 'guest-user';
   };

   type RequestContext = AuthenticatedContext | GuestContext;  // Discriminated union
   ```

2. **createContext.ts** implements:
   - Takes `authHeader` and `authClient` as inputs
   - Calls `authClient.verifyToken(authHeader)` to validate JWT via cwc-auth service
   - Returns `AuthenticatedContext` on success, `GuestContext` on failure
   - **Graceful degradation:** No JWT, invalid token, expired token, or auth service error all result in guest context (logged but no error thrown)
   - Uses cwc-auth's `/verify-token` endpoint (internal service endpoint)

### Express Service Setup (Phase 1 - Complete)
**Location:** `src/index.ts`

The main entry point demonstrates the standard service pattern:

```typescript
// 1. Load environment variables with loadDotEnv utility
loadDotEnv({
  serviceName: 'cwc-api',
  environment: process.env['RUNTIME_ENVIRONMENT'] as RuntimeEnvironment,
  debug: process.env['DEBUG_MODE'] === 'ON',
});

// 2. Load & validate configuration
const config = loadConfig();

// 3. Create BackendUtilsConfig adapter
const backendConfig = createBackendUtilsConfig(config);

// 4. Create Logger (database-backed for errors)
const logger = new Logger({ config: backendConfig, serviceName: 'cwc-api' });

// 5. Create API instances (health check + CwcApiV1 when implemented)
const healthApi: ExpressApi = {
  version: 1,
  path: '/health/v1',
  handler: healthHandler,
};
const apis: ExpressApi[] = [healthApi];

// 6. Create Express service with middleware
const service = createExpressService({
  config: backendConfig,
  serviceName: 'cwc-api',
  apis,
  allowGet: false,
  allowOptions: true,
  allowPost: true,
  payloadLimit: undefined,
});

// 7. Start service with graceful shutdown handlers
service.start(apis);
```

**Note:** SqlClient and AuthClient creation are commented out until Phase 3 (Handler Architecture) is implemented.

## 2. CWC-AUTH Handler Patterns (Reference Implementation)

### Architecture Overview
CWC-auth provides a complete, production-grade handler pattern that cwc-api should follow for Phase 3+.

**File Structure:**

    └── workers/
        └── renewSessionWorker.ts
```

### Handler Pattern - Three-Layer Delegation

**Layer 1: ExpressApi Class (index.ts)**
- Implements `ExpressApi` interface with `path`, `version`, and `handler()` method
- Receives raw Express `Request` and `Response`
- Validates HTTP method and route existence
- Extracts headers/body from request
- Creates handler instance and orchestrates response

```typescript
export class LogonApiV1 implements ExpressApi {
  public get path(): string { return '/auth/v1'; }
  public get version(): number { return 1; }
  
  public async handler(req: Request, res: Response, _next: NextFunction): Promise<void> {
    // 1. Validate route exists
    const routeConfig = this.routes[req.path];
    if (!routeConfig) {
      res.status(404).json({ ... });
      return;
    }
    
    // 2. Validate HTTP method
    if (req.method !== routeConfig.method) {
      res.status(404).json({ ... });
      return;
    }
    
    // 3. Extract request data
    const authHeader = req.headers['authorization'] as string | undefined;
    const payload: AuthRequestPayload = req.body ?? {};
    
    // 4. Create handler and execute
    const handler = new LogonHandler(
      { payload, authHeader, routeConfig },
      this.config,
      this.logger
    );
    const response = await handler.processRequest();
    
    // 5. Send response
    res.status(response.statusCode).json({
      data: response.data,
      jwt: response.jwt,
    });
  }
}
```

**Layer 2: Handler Class (LogonHandler.ts)**
- Encapsulates a single route's business logic
- Receives request details in constructor
- Implements `AuthRouteHandler` interface with `processRequest()` method
- Delegates actual work to worker function
- Transforms worker result to standard response format
- Handles errors with appropriate HTTP status codes

```typescript
export class LogonHandler implements AuthRouteHandler {
  constructor(
    options: AuthRouteHandlerOptions,    // payload, authHeader, routeConfig
    config: CwcAuthConfig,
    logger: ILogger | undefined
  ) { ... }

  public async processRequest(): Promise<AuthRouteHandlerResponse> {
    try {
      const result = await this.routeConfig.worker(options);
      
      if (result.success) {
        return {
          statusCode: 200,
          data: { success: true, jwtType: 'user', ... },
          jwt: result.jwt,
        };
      }
      
      // Error handling with dev-only details
      return {
        statusCode: 401,
        data: {
          success: false,
          jwtType: undefined,
          ...(this.config.isDevelopment && {
            errorCode: result.errorCode,
            errorDetail: result.errorDetail,
          }),
        },
        jwt: undefined,
      };
    } catch (error) {
      this.logger?.logError({ ... });
      return { statusCode: 401, data: { success: false, ... }, jwt: undefined };
    }
  }
}
```

**Layer 3: Worker Function (logonWorker.ts)**
- Pure business logic function
- Receives injected dependencies (sqlClient, config, logger)
- Returns success/failure result (never throws)
- Composed from reusable auth functions (createAuthenticateUser, etc.)

```typescript
export function createLogonWorker(deps: AuthDependencies) {
  const authenticateUser = createAuthenticateUser(deps);

  return async function logonWorker(
    options: AuthFunctionOptions
  ): Promise<AuthFunctionResult> {
    const result = await authenticateUser({
      username: options.payload['username'] as string,
      password: options.payload['password'] as string,
      kulo: options.payload['kulo'] as boolean | undefined,
    });

    if (result.success) {
      return { success: true, jwt: result.jwt, userPkId: result.userPkId, ... };
    }
    return { success: false, errorCode: result.errorCode, errorDetail: result.errorDetail };
  };
}
```

### Route Configuration Pattern

Routes are centralized in `routes.ts` as a factory function:

```typescript
export const getRoutes = (deps: AuthDependencies): AuthRouteConfigs => {
  const logonWorker = createLogonWorker(deps);
  const logoffWorker = createLogoffWorker(deps);

  return {
    '/logon': {
      handlerType: 'logon',
      path: '/logon',
      method: 'POST',
      requiresAuth: false,
      worker: logonWorker,
    },
    '/logoff': {
      handlerType: 'logoff',
      path: '/logoff',
      method: 'POST',
      requiresAuth: true,
      worker: logoffWorker,
    },
  };
};
```

### Response Formatting Pattern

**LogonApiV1 Response:**
```typescript
type AuthRouteHandlerResponse = {
  statusCode: 200 | 401;
  data: {
    success: boolean;
    loggedOff?: boolean;
    jwtType: AuthJwtType;  // 'user' | 'temp' | undefined
    errorCode?: string;    // Dev-only
    errorDetail?: string;  // Dev-only
  };
  jwt: string | undefined;
};
```

**ServiceApiV1 Response (for renew-session):**
```typescript
type ServiceRouteHandlerResponse = {
  statusCode: 200 | 401 | 403;
  data: {
    success: boolean;
    jwtType: AuthJwtType;
    payload?: UserJwtPayload;  // Optionally include updated claims
    errorCode?: string;        // Dev-only
    errorDetail?: string;      // Dev-only
  };
  jwt: string | undefined;
};
```

### Session Renewal Pattern

The `ServiceApiV1` demonstrates internal service-to-service pattern:
- Protected by Docker network isolation + JWT validation
- `renewSessionWorker` re-queries database for fresh `ownedProjects`
- Returns new JWT with updated claims
- Used by cwc-api after create/delete project operations

---

## 3. CWC-Backend-Utils Shared Components

### AuthClient Pattern
**Location:** `packages/cwc-backend-utils/src/AuthClient/AuthClient.ts`

Provides HTTP client for cwc-auth service, following same pattern as SqlClient:

```typescript
export class AuthClient {
  async verifyToken(authHeader: string | undefined): Promise<VerifyTokenResult> {
    if (!authHeader) return { success: false, error: 'MISSING_TOKEN' };
    
    try {
      const response = await axios.post<VerifyTokenResponse>(
        `${this.config.authUri}/verify-token`,
        {},
        { headers: { Authorization: authHeader }, timeout: 5000 }
      );
      
      if (response.data.success) {
        return { success: true, payload: response.data.payload };
      }
      return { success: false, error: response.data.errorCode ?? 'UNKNOWN_ERROR' };
    } catch (error) {
      if (axios.isAxiosError(error) && error.response?.status === 401) {
        return { success: false, error: 'INVALID_TOKEN' };
      }
      this.logger?.logError({ ... });
      return { success: false, error: 'AUTH_SERVICE_ERROR' };
    }
  }
}
```

**Key characteristics:**
- Graceful error handling (returns typed result, never throws)
- Logs unexpected network errors only (not auth failures)
- Follows same config + logger + clientName pattern as SqlClient

### Express Service Factory Pattern
**From cwc-backend-utils:**
- Applied consistently across cwc-auth and cwc-api
- Automatically applies middleware: rate limiting, Helmet, CORS, invalid routes
- Takes `ExpressApi[]` array for modular endpoint registration

### Configuration Adapter Pattern
Both services use config adapter function to convert service-specific config to `BackendUtilsConfig`:

```typescript
function createBackendUtilsConfig(apiConfig: CwcApiConfig): BackendUtilsConfig {
  return {
    debugMode: apiConfig.debugMode,
    dataUri: apiConfig.dataUri,
    logErrorsToDatabase: apiConfig.logErrorsToDatabase,
    // ... rest of config fields
  };
}
```

---

## 4. Type System and Response Patterns

### Role Types (from cwc-types)
```typescript
type CwcRole = 'project-owner' | 'logged-on-user' | 'guest-user';
```

**Usage in context:**
- `project-owner`: User owns the specific project/content being accessed
- `logged-on-user`: Authenticated user but not necessarily owner
- `guest-user`: Unauthenticated request (read-only access)

### JWT Payload Structure
```typescript
type UserJwtPayload = {
  jti: string;              // userJwtId (UUID)
  sub: number;              // userPkId
  iat: number;              // Issued at (Unix timestamp)
  exp: number;              // Expiration (Unix timestamp)
  login: CwcLoginClaims;    // Custom claims
};

type CwcLoginClaims = {
  username: string;
  deviceId: string;
  userJwtId: string;
  loginType: 'cwc' | 'facebook' | 'google';
  kulo: boolean;            // Keep-user-logged-on flag
  ownedProjects: string[];  // Array of projectId (natural keys)
  isGuestUser: boolean;     // Always false in JWT
};
```

### Verify Token Response Types (from cwc-types)
```typescript
type VerifyTokenSuccessResponse = {
  success: true;
  jwtType: undefined;
  payload: UserJwtPayload;
};

type VerifyTokenErrorResponse = {
  success: false;
  jwtType: undefined;
  errorCode?: string;    // Dev-only
  errorDetail?: string;  // Dev-only
};

type VerifyTokenResult = 
  | { success: true; payload: UserJwtPayload }
  | { success: false; error: string };
```

---

## 5. Critical Patterns & Rules Summary

### Phase 1-2 Complete ✓
- Express service setup with graceful shutdown
- Config loading and validation
- Context layer with graceful degradation
- Health check endpoint

### Phase 3 Ready (Handler Architecture)
When implementing cwc-api handlers following auth pattern:

**Must follow:**
1. Three-layer delegation: ExpressApi → Handler → Worker
2. Route factory function returning route configs
3. Handler class implementing route handler interface
4. Worker functions with injected dependencies
5. Graceful error handling (log + return error result, never throw)
6. Dev-only error details (errorCode, errorDetail only in isDevelopment mode)
7. Type-safe response envelopes
8. Standard HTTP status codes (200, 401, 403, 404)

**Key differences for cwc-api:**
- Must create SqlClient in index.ts (commented out for Phase 2)
- Must create AuthClient for JWT verification
- Response structure will include `data` + `pagination` metadata (offset-based)
- Will implement QueryHandler (read) and MutationHandler (write) in addition to RouteHandler

### Configuration
**cwc-api required environment variables:**
```bash
RUNTIME_ENVIRONMENT=dev|test|prod
SERVICE_PORT=5040
DATA_URI=http://localhost:5020/data/v1
AUTH_URI=http://localhost:5005/auth/v1
APP_URL=http://localhost:3000
CORS_ORIGIN=*
DEV_CORS_ORIGIN=http://localhost:3000
RATE_LIMITER_POINTS=15
RATE_LIMITER_DURATION=1
DEBUG_MODE=OFF|ON
LOG_ERRORS_TO_DATABASE=ON|OFF
USER_JWT_SECRET=...
SQL_CLIENT_API_KEY=...
```

### Testing Infrastructure
- Mock infrastructure in `src/__tests__/mocks/`
- Mock functions for SqlClient, AuthClient, Logger, Config
- Test config loading from `unit.cwc-api.env`
- Setup file loads environment via `loadDotEnv`

{
  "subagent_type": "Plan",
  "prompt": "Design the Phase 3 Handler Architecture for cwc-api package.\n\n## Context from Exploration\n\n**Current State (Phase 1 & 2 Complete):**\n- Express service running with health endpoint at `/health/v1`\n- Context layer complete: `src/context/createContext.ts` creates `AuthenticatedContext` or `GuestContext`\n- Uses `AuthClient.verifyToken()` from cwc-backend-utils to validate JWTs via cwc-auth\n\n**Reference Implementation (cwc-auth):**\n- 3-layer pattern: ExpressApi (index.ts) → Handler class → Worker function\n- ExpressApi validates route/method, extracts headers, creates handler, sends response\n- Handler class implements `processRequest()` method, delegates to worker, formats response\n- Worker function contains business logic with injected dependencies\n- Types defined in `types.ts`, routes in `routes.ts` as factory function\n\n**Key Files:**\n- cwc-auth ExpressApi: `/packages/cwc-auth/src/apis/LogonApiV1/index.ts`\n- cwc-auth Handler: `/packages/cwc-auth/src/apis/LogonApiV1/LogonHandler.ts`\n- cwc-auth Types: `/packages/cwc-auth/src/apis/LogonApiV1/types.ts`\n- cwc-auth Routes: `/packages/cwc-auth/src/apis/LogonApiV1/routes.ts`\n- cwc-api Context: `/packages/cwc-api/src/context/context.types.ts`\n- AuthClient: `/packages/cwc-backend-utils/src/AuthClient/AuthClient.ts`\n\n**Phase 3 Checklist Items:**\n1. Create `src/handlers/handler.types.ts` - route/query/mutation handler types\n2. Create `src/handlers/RouteHandler.ts` - Extract JWT, create context, check route access, delegate\n3. Create `src/handlers/QueryHandler.ts` - Operation access check, execute query, format response\n4. Create `src/handlers/MutationHandler.ts` - Operation access check, execute mutation, renew session\n5. Create `src/handlers/index.ts` - Exports\n\n## Identified Prerequisites\n\n**CRITICAL PREREQUISITE - AuthClient.renewSession():**\n- Current AuthClient only has `verifyToken()` method\n- MutationHandler needs `renewSession()` to call cwc-auth `/renew-session` after project create/delete\n- Requires:\n  1. Add `RenewSessionResult` type to cwc-types/src/authTypes.ts\n  2. Add `renewSession()` method to cwc-backend-utils AuthClient\n\n**Response Types:**\n- cwc-api needs standardized response envelope: `{ success, data?, pagination?, errorCode?, errorMessage? }`\n- Different from cwc-auth which uses `{ data, jwt }` envelope\n\n## Architecture Decisions to Consider\n\n1. **Where do access policy checks happen?**\n   - Phase 4 implements the actual policies\n   - Phase 3 should define interfaces/types that Phase 4 implements\n   - RouteHandler calls `checkRouteAccess(context, routeConfig)` - returns allow/deny\n   - Query/MutationHandler calls `checkOperationAccess(context, operation, resourceId)` - returns allow/deny\n\n2. **How do handlers integrate with CwcApiV1 (Phase 6)?**\n   - CwcApiV1 will be the ExpressApi class (like LogonApiV1)\n   - RouteHandler receives request details and orchestrates the flow\n   - Operations will be registered in routes.ts as factory function\n\n3. **Session renewal trigger:**\n   - Only after project create/delete operations (changes ownedProjects claim)\n   - MutationHandler checks if operation requires session renewal\n   - Calls `authClient.renewSession(authHeader)` and includes new JWT in response\n\n## Required Deliverables\n\nPlease design:\n1. Complete type definitions for handler.types.ts\n2. RouteHandler class structure and processRequest flow\n3. QueryHandler class structure \n4. MutationHandler class structure with session renewal logic\n5. How to integrate with existing createContext()\n6. Interface definitions for access policy checks (stubs for Phase 4)\n7. Response formatting patterns\n8. Test strategy for unit tests\n\nConsider:\n- Following cwc-auth patterns where applicable\n- Defining interfaces that Phase 4-6 will implement\n- Error handling patterns (dev-only error details)\n- Type safety throughout\n",
  "description": "Design Phase 3 handler architecture"
}

Now I have a comprehensive understanding of the codebase. Let me present my design for the Phase 3 Handler Architecture.

---

# Phase 3 Handler Architecture Design for cwc-api

## Overview

This design document outlines the handler architecture for cwc-api Phase 3. The architecture follows the established 3-layer pattern from cwc-auth (ExpressApi -> Handler -> Worker) while adapting it for cwc-api's specific needs: role-based access control, query/mutation separation, and session renewal for ownership-changing operations.

---

## 1. Prerequisites (Before Phase 3 Implementation)

### 1.1 Add RenewSessionResult Type to cwc-types

**File:** `/packages/cwc-types/src/authTypes.ts`

```typescript
/**
 * Success response from cwc-auth /renew-session
 */
export type RenewSessionSuccessResponse = {
  success: true;
  jwtType: 'user';
  jwt: string;
};

/**
 * Error response from cwc-auth /renew-session
 */
export type RenewSessionErrorResponse = {
  success: false;
  jwtType: undefined;
  errorCode?: string | undefined; // Dev-only
  errorDetail?: string | undefined; // Dev-only
};

/**
 * Union of renew-session responses
 */
export type RenewSessionResponse = RenewSessionSuccessResponse | RenewSessionErrorResponse;

/**
 * Result from AuthClient.renewSession()
 */
export type RenewSessionResult =
  | { success: true; jwt: string }
  | { success: false; error: string };
```

### 1.2 Add renewSession Method to AuthClient

**File:** `/packages/cwc-backend-utils/src/AuthClient/AuthClient.ts`

Add the `renewSession()` method following the same pattern as `verifyToken()`:

```typescript
/**
 * Renew a session by calling cwc-auth /renew-session
 * Used after project create/delete to update ownedProjects claim
 */
async renewSession(authHeader: string | undefined): Promise<RenewSessionResult> {
  if (!authHeader) {
    return { success: false, error: 'MISSING_TOKEN' };
  }

  try {
    const response = await axios.post<RenewSessionResponse>(
      `${this.config.authUri}/renew-session`,
      {},
      {
        headers: { Authorization: authHeader },
        timeout: this.config.timeout ?? 5000,
      }
    );

    const data = response.data;

    if (data.success) {
      return { success: true, jwt: data.jwt };
    }

    return { success: false, error: data.errorCode ?? 'UNKNOWN_ERROR' };
  } catch (error) {
    // Handle 401 responses
    if (axios.isAxiosError(error) && error.response?.status === 401) {
      const errorData = error.response.data as RenewSessionErrorResponse;
      return { success: false, error: errorData.errorCode ?? 'RENEWAL_FAILED' };
    }

    this.logger?.logError({
      userPkId: undefined,
      codeLocation,
      message: `[${this.clientName}] Failed to renew session with auth service`,
      error,
    });

    return { success: false, error: 'AUTH_SERVICE_ERROR' };
  }
}
```

### 1.3 Update Mock AuthClient

**File:** `/packages/cwc-api/src/__tests__/mocks/authClient.mock.ts`

Add mock helpers for renewSession:

```typescript
export function createMockAuthClient(): jest.Mocked<AuthClient> {
  return {
    verifyToken: jest.fn<(authHeader: string | undefined) => Promise<VerifyTokenResult>>(),
    renewSession: jest.fn<(authHeader: string | undefined) => Promise<RenewSessionResult>>(),
  } as unknown as jest.Mocked<AuthClient>;
}

export function mockRenewSessionSuccess(
  mockAuthClient: jest.Mocked<AuthClient>,
  jwt: string = 'new-jwt-token'
): void {
  mockAuthClient.renewSession.mockResolvedValueOnce({
    success: true,
    jwt,
  });
}

export function mockRenewSessionFailure(
  mockAuthClient: jest.Mocked<AuthClient>,
  error: string = 'RENEWAL_FAILED'
): void {
  mockAuthClient.renewSession.mockResolvedValueOnce({
    success: false,
    error,
  });
}
```

## 7. Integration with CwcApiV1 (Phase 6 Preview)

The handlers are designed to integrate with the CwcApiV1 ExpressApi class (Phase 6). Here's how it will work:

**File Preview:** `/packages/cwc-api/src/apis/CwcApiV1/index.ts`

```typescript
// Phase 6 will implement this
public async handler(req: Request, res: Response, _next: NextFunction): Promise<void> {
  // 1. Find route config
  const routeConfig = this.routes[`${req.method}:${req.path}`];
  
  // 2. Create context using existing createContext()
  const context = await createContext({
    authHeader: req.headers.authorization,
    authClient: this.authClient,
  });
  
  // 3. Create and execute RouteHandler
  const handler = new RouteHandler(
    {
      context,
      routeConfig,
      authHeader: req.headers.authorization,
      payload: req.body,
      pathParams: req.params,
      queryParams: req.query as Record<string, string>,
    },
    this.config,
    this.authClient,
    this.logger
  );
  
  const response = await handler.processRequest();
  
  // 4. Send response
  res.status(response.statusCode).json(response.body);
}
```

## 8. Test Strategy

### 8.1 Unit Test Structure

```
src/__tests__/handlers/
  RouteHandler.test.ts
  QueryHandler.test.ts
  MutationHandler.test.ts
```

### 8.2 RouteHandler Tests

```typescript
// RouteHandler.test.ts
describe('RouteHandler', () => {
  describe('Route Access Control', () => {
    it('should return 401 for guest user accessing authenticated route');
    it('should return 403 for logged-on-user accessing project-owner-only route');
    it('should allow guest user to access guest-allowed routes');
    it('should allow authenticated user to access logged-on-user routes');
  });

  describe('Handler Delegation', () => {
    it('should delegate to QueryHandler for query handlerType');
    it('should delegate to MutationHandler for mutation handlerType');
  });

  describe('Operation Context', () => {
    it('should pass projectId from path params to operation context');
    it('should pass resourceId from path params to operation context');
  });

  describe('Error Handling', () => {
    it('should catch errors and return 500 response');
    it('should include error detail in development mode');
    it('should not include error detail in production mode');
  });
});
```

### 8.3 QueryHandler Tests

```typescript
// QueryHandler.test.ts
describe('QueryHandler', () => {
  describe('Successful Operations', () => {
    it('should return 200 with data on successful query');
    it('should include pagination when operation returns it');
  });

  describe('Error Responses', () => {
    it('should return 404 for NOT_FOUND error code');
    it('should return 400 for VALIDATION_ERROR');
    it('should return 500 for unknown errors');
  });

  describe('Operation Access', () => {
    it('should stub operation access as allowed (Phase 3)');
  });
});
```

### 8.4 MutationHandler Tests

```typescript
// MutationHandler.test.ts
describe('MutationHandler', () => {
  describe('Successful Operations', () => {
    it('should return 201 for POST operations');
    it('should return 200 for PUT operations');
    it('should return 200 for DELETE operations');
  });

  describe('Session Renewal', () => {
    it('should call renewSession for project-create trigger');
    it('should call renewSession for project-delete trigger');
    it('should not call renewSession when no trigger configured');
    it('should include new JWT in response on successful renewal');
    it('should log warning but succeed when renewal fails');
    it('should not attempt renewal for guest context');
  });

  describe('Error Responses', () => {
    it('should return 404 for NOT_FOUND error code');
    it('should return 400 for ALREADY_EXISTS error code');
    it('should return 500 for database errors');
  });
});
```

### 8.5 Mock Extensions Needed

Add to `/packages/cwc-api/src/__tests__/mocks/`:

```typescript
// routeConfig.mock.ts
export function createMockRouteConfig(
  overrides: Partial<CwcApiRouteConfig> = {}
): CwcApiRouteConfig {
  return {
    path: '/test',
    method: 'GET',
    handlerType: 'query',
    allowedRoles: ['guest-user', 'logged-on-user'],
    operation: jest.fn().mockResolvedValue({ success: true, data: {} }),
    ...overrides,
  };
}

export function createMockOperationContext(
  overrides: Partial<OperationContext> = {}
): OperationContext {
  return {
    context: { isAuthenticated: false, role: 'guest-user' },
    ...overrides,
  };
}
```

---

## 9. Implementation Order

1. **Phase 3a: Prerequisites**
   - Add `RenewSessionResult` types to cwc-types
   - Add `renewSession()` method to AuthClient
   - Add mock helpers for renewSession

2. **Phase 3b: Core Types**
   - Create `src/handlers/handler.types.ts`

3. **Phase 3c: QueryHandler**
   - Create `src/handlers/QueryHandler.ts`
   - Create `src/__tests__/handlers/QueryHandler.test.ts`

4. **Phase 3d: MutationHandler**
   - Create `src/handlers/MutationHandler.ts`
   - Create `src/__tests__/handlers/MutationHandler.test.ts`

5. **Phase 3e: RouteHandler**
   - Create `src/handlers/RouteHandler.ts`
   - Create `src/__tests__/handlers/RouteHandler.test.ts`

6. **Phase 3f: Exports**
   - Create `src/handlers/index.ts`
   - Update `src/__tests__/mocks/index.ts` with new mocks

---

## 10. Key Design Decisions

### 10.1 Why Separate Query and Mutation Handlers?

- **Session Renewal**: Only mutations can trigger session renewal (project create/delete)
- **HTTP Status Codes**: POST returns 201, GET always returns 200
- **Future Caching**: Queries could be cached, mutations cannot
- **Single Responsibility**: Each handler has a focused purpose

### 10.2 Why Phase 4 Stubs for Access Policies?

- **Separation of Concerns**: Handler architecture is independent of access policy logic
- **Testability**: Handlers can be tested without complex policy setup
- **Incremental Development**: Phase 4 implements policies, Phase 3 provides the hooks

### 10.3 Why Return Objects Instead of Throwing?

- **Consistent Flow**: All responses go through the same formatting
- **No Try/Catch Pollution**: Operation errors are handled as data, not exceptions
- **Type Safety**: OperationResult union type enforces handling both cases

### 10.4 Why JWT in Response Body (Not Header)?

- **Consistency**: All data in JSON body, following cwc-auth pattern
- **Client Simplicity**: Client always reads response body, no header inspection
- **Optional Field**: Only present when session was renewed

---

### Critical Files for Implementation

1. **`/packages/cwc-types/src/authTypes.ts`** - Add RenewSessionResult types (prerequisite)
2. **`/packages/cwc-backend-utils/src/AuthClient/AuthClient.ts`** - Add renewSession method (prerequisite)
3. **`/packages/cwc-api/src/handlers/handler.types.ts`** - Core type definitions for entire handler system
4. **`/packages/cwc-api/src/handlers/MutationHandler.ts`** - Most complex handler with session renewal logic
5. **`/packages/cwc-api/src/context/createContext.ts`** - Existing context creation to integrate with
agentId: a5789af (for resuming to continue this agent's work if needed)

     1→# cwc-api Package
     2→
     3→Main business logic API for CWC application. Acts as the central orchestrator that handles CRUD operations, enforces business rules, and coordinates data flow between frontend applications and the database layer.
     4→
     5→## Architecture
     6→
     7→**Database-Connected Microservice:**
     8→
     9→- Uses SqlClient from `cwc-backend-utils` to communicate with cwc-sql
    10→- Uses database-backed Logger for error logging
    11→- Never connects directly to database - all data access flows through cwc-sql
    12→- Coordinates with cwc-auth for session renewal
    13→
    14→**Layered Architecture:**
    15→
    16→```
    17→Request → RouteHandler → QueryHandler/MutationHandler → SqlFunctions → SqlClient → cwc-sql
    18→```
    19→
    20→- **RouteHandler**: Auth → context creation → route access check → delegation
    21→- **QueryHandler**: Operation access check → execute query → format response
    22→- **MutationHandler**: Operation access check → execute mutation → session renewal → format response
    23→- **SqlFunctions**: Atomic database operations (one function per table operation)
    24→
    25→## Request Pipeline
    26→
    27→1. Express routes receive incoming HTTP requests
    28→2. RouteHandler extracts JWT from Authorization header
    29→3. JWT validated → authenticated context; No JWT → guest context
    30→4. Route-level access policy checked
    31→5. QueryHandler or MutationHandler executes business logic
    32→6. SqlFunctions handle database operations through SqlClient
    33→7. Response returned (with new JWT if session renewed)
    34→
    35→## Context Layer - Centralized Authentication
    36→
    37→**Location:** `src/context/`
    38→
    39→**Architecture Decision:** cwc-api does NOT duplicate JWT verification logic. All token validation goes through cwc-auth's `/auth/v1/verify-token` endpoint via AuthClient.
    40→
    41→**Trade-off:** Additional HTTP call per request, but auth logic stays centralized in cwc-auth (single source of truth).
    42→
    43→**Files:**
    44→- `context.types.ts` - AuthenticatedContext, GuestContext, RequestContext types
    45→- `createContext.ts` - Creates context from Authorization header
    46→- `index.ts` - Exports
    47→
    48→**Context Types:**
    49→
    50→```typescript
    51→// Authenticated user (valid JWT)
    52→type AuthenticatedContext = {
    53→  isAuthenticated: true;
    54→  role: 'project-owner' | 'logged-on-user';  // Determined per-operation
    55→  userPkId: number;
    56→  username: string;
    57→  ownedProjects: string[];
    58→  payload: UserJwtPayload;
    59→};
    60→
    61→// Unauthenticated request (no/invalid JWT)
    62→type GuestContext = {
    63→  isAuthenticated: false;
    64→  role: 'guest-user';
    65→};
    66→
    67→type RequestContext = AuthenticatedContext | GuestContext;
    68→```
    69→
    70→**Usage:**
    71→```typescript
    72→import { createContext } from './context';
    73→import { AuthClient } from 'cwc-backend-utils';
    74→
    75→const context = await createContext({
    76→  authHeader: req.headers.authorization,
    77→  authClient: authClient,
    78→});
    79→
    80→if (context.isAuthenticated) {
    81→  // TypeScript narrows to AuthenticatedContext
    82→  console.log(context.userPkId, context.ownedProjects);
    83→} else {
    84→  // TypeScript narrows to GuestContext
    85→  console.log(context.role);  // 'guest-user'
    86→}
    87→```
    88→
    89→**Graceful Degradation:**
    90→- Missing token → guest context
    91→- Invalid token → guest context
    92→- Expired token → guest context
    93→- Auth service error → guest context (logged)
    94→- No errors thrown; auth failures result in guest access
    95→
    96→## Role-Based Access Control
    97→
    98→**Roles:**
    99→
   100→| Role | Description |
   101→|------|-------------|
   102→| `project-owner` | User owns the project being accessed |
   103→| `logged-on-user` | Authenticated user (may not own the project) |
   104→| `guest-user` | Unauthenticated request (read-only access) |
   105→
   106→**Access Policy Levels:**
   107→
   108→- **Route-level**: Can this role call this endpoint at all?
   109→- **Operation-level**: Can this role execute this specific operation?
   110→- **Context-aware**: Does the user have the right relationship to the data? (e.g., ownership)
   111→
   112→## Tables Handled
   113→
   114→**Content Tables (Full CRUD + Soft Delete):**
   115→
   116→- project
   117→- codingSession
   118→- codingSessionContent
   119→- codingSessionAttachment
   120→- comment
   121→- reaction
   122→- contentReport
   123→- abuseReport
   124→
   125→**Read-Only Tables:**
   126→
   127→- featureFlag (all fields)
   128→- user (limited fields: userPkId, enabled, username, loginType, loginDate, otpValidated)
   129→
   130→## SqlFunction Naming Convention
   131→
   132→Each table has a subdirectory in `src/sql/` with these functions:
   133→
   134→| Function | Purpose |
   135→|----------|---------|
   136→| `select{Table}.ts` | Retrieve single record by identifier |
   137→| `list{Table}s.ts` | Retrieve multiple records with filtering |
   138→| `insert{Table}.ts` | Create new record |
   139→| `update{Table}.ts` | Modify existing record |
   140→| `delete{Table}.ts` | Hard delete (GDPR compliance) |
   141→| `softDelete{Table}.ts` | Soft delete (set enabled=false) |
   142→
   143→**Key Principles:**
   144→
   145→- Single responsibility: Each SqlFunction does one thing
   146→- No business logic: SqlFunctions handle data access only
   147→- Soft-delete awareness: List queries automatically filter `enabled=true`
   148→- Composability: Queries/Mutations compose multiple SqlFunctions
   149→
   150→## cwc-auth Integration
   151→
   152→**Division of Responsibilities:**
   153→
   154→| Concern | Owner |
   155→|---------|-------|
   156→| "Is this token valid?" | cwc-auth |
   157→| "Who is this user?" | cwc-auth (via token claims) |
   158→| "Can this user access this endpoint?" | cwc-api |
   159→| "Is this user the owner of this project?" | cwc-api |
   160→
   161→**Session Renewal Flow:**
   162→
   163→When cwc-api creates/deletes a project:
   164→1. cwc-api performs the database operation
   165→2. cwc-api calls cwc-auth `/auth/v1/renew-session`
   166→3. cwc-auth issues new JWT with updated `ownedProjects`
   167→4. cwc-api returns new JWT to client
   168→
   169→## Response Pattern
   170→
   171→**Standard Response Envelope:**
   172→
   173→```typescript
   174→// Success
   175→{
   176→  success: true,
   177→  data: { ... },
   178→  // Optional: pagination metadata
   179→}
   180→
   181→// Error
   182→{
   183→  success: false,
   184→  errorCode: 'ERROR_CODE',
   185→  errorMessage: 'Human-readable message',
   186→  // Dev-only: errorDetail
   187→}
   188→```
   189→
   190→**Pagination (Offset-based):**
   191→
   192→```typescript
   193→{
   194→  success: true,
   195→  data: [...],
   196→  pagination: {
   197→    page: 1,
   198→    pageSize: 20,
   199→    totalCount: 100,
   200→    hasMore: true
   201→  }
   202→}
   203→```
   204→
   205→## Configuration
   206→
   207→**Required Environment Variables:**
   208→
   209→```bash
   210→RUNTIME_ENVIRONMENT=dev
   211→SERVICE_PORT=5040
   212→DATA_URI=http://localhost:5020/data/v1
   213→AUTH_URI=http://localhost:5005/auth/v1
   214→APP_URL=http://localhost:3000
   215→CORS_ORIGIN=*
   216→DEV_CORS_ORIGIN=http://localhost:3000
   217→RATE_LIMITER_POINTS=15
   218→RATE_LIMITER_DURATION=1
   219→DEBUG_MODE=OFF
   220→LOG_ERRORS_TO_DATABASE=ON
   221→USER_JWT_SECRET=...
   222→SQL_CLIENT_API_KEY=...
   223→```
   224→
   225→## API Versioning
   226→
   227→**URL-based versioning:**
   228→
   229→- `/api/v1/*` routes to CwcApiV1 handlers
   230→- Each version lives in `src/apis/CwcApiV{N}/`
   231→- Route definitions in `routes.ts`, organized alphabetically
   232→
   233→## Critical Rules
   234→
   235→**SqlClient Usage:**
   236→
   237→- Never provide `createdDate` or `modifiedDate` - handled by cwc-sql automatically
   238→- Always use SqlFunctions, never construct queries directly in business logic
   239→
   240→**Guest User Handling:**
   241→
   242→- No JWT required - RouteHandler creates context with `role: 'guest-user'`
   243→- Guest users have read-only access to public content
   244→
   245→**Soft Delete:**
   246→
   247→- All content tables support soft delete (`enabled=false`)
   248→- Hard delete available for GDPR compliance
   249→- List queries automatically filter `enabled=true`
   250→
   251→## Implementation Status
   252→
   253→**Active Development:** This package is being implemented following `cwc-api-implementation-checklist.md`.
   254→
   255→The checklist tracks 7 phases:
   256→1. Package Foundation (config, Express service, health check) - **Complete**
   257→2. Authentication & Context Layer (JWT, request context) - **Complete**
   258→3. Handler Architecture (RouteHandler, QueryHandler, MutationHandler)
   259→4. Access Policy System (route and operation policies)
   260→5. SqlFunction Layer (CRUD operations for all tables)
   261→6. CwcApiV1 Routes & Business Logic
   262→7. Integration Testing & Final Review
   263→
   264→Each phase includes: Implementation → Unit Tests → Security Review → Documentation Updates
   265→
   266→## Unit Testing

    42→## Phase 2: Authentication & Context Layer
    43→
    44→**Architecture Decision:** cwc-api does NOT duplicate JWT verification logic. Instead, cwc-api
    45→calls cwc-auth's `/auth/v1/verify-token` endpoint to validate tokens. This keeps auth logic
    46→centralized in cwc-auth (single source of truth) at the cost of an additional HTTP call per request.
    47→
    48→**Architecture Refinement (Session 020):** Shared types moved to cwc-types, AuthClient moved to
    49→cwc-backend-utils for reuse by other services.
    50→
    51→### Prerequisites (cwc-auth work)
    52→- [x] Add `/auth/v1/verify-token` endpoint to cwc-auth ServiceApiV1
    53→  - Input: JWT token (from Authorization header)
    54→  - Output: `{ success: true, payload: UserJwtPayload }` or `{ success: false, error: ... }`
    55→
    56→### Shared Auth Types (cwc-types)
    57→- [x] Create `cwc-types/src/authTypes.ts`
    58→  - [x] Define `UserJwtPayload` type (moved from cwc-auth for sharing)
    59→  - [x] Define `CwcRole` type: `'project-owner' | 'logged-on-user' | 'guest-user'`
    60→  - [x] Define `VerifyTokenResponse` types (success/error)
    61→  - [x] Define `VerifyTokenResult` type
    62→- [x] Update cwc-auth to import `UserJwtPayload` from cwc-types
    63→
    64→### AuthClient (cwc-backend-utils)
    65→- [x] Create `cwc-backend-utils/src/AuthClient/AuthClient.ts`
    66→  - [x] HTTP POST to cwc-auth `/auth/v1/verify-token`
    67→  - [x] Handles success and error responses
    68→  - [x] Returns typed `VerifyTokenResult`
    69→- [x] Export from `cwc-backend-utils/src/index.ts`
    70→
    71→### Request Context (cwc-api)
    72→- [x] Create `src/context/context.types.ts`
    73→  - [x] Define `AuthenticatedContext` and `GuestContext` types
    74→  - [x] Define `RequestContext` union type
    75→- [x] Create `src/context/createContext.ts`
    76→  - [x] Uses AuthClient.verifyToken()
    77→  - [x] Returns authenticated context on success
    78→  - [x] Returns guest context on failure (no JWT, invalid, expired)
    79→- [x] Create `src/context/index.ts`
    80→
    81→### Unit Tests
    82→- [x] Create `src/__tests__/mocks/authClient.mock.ts` - AuthClient mock helpers
    83→- [x] Create `src/__tests__/context/createContext.test.ts` - Test authenticated and guest contexts (10 tests)
    84→
    85→### Security Review
    86→- [x] Verify cwc-auth endpoint validates JWT signature (HS256, proper secret)
    87→- [x] Verify expired tokens are rejected by cwc-auth
    88→- [x] Verify invalid tokens create guest context (no error details leaked to client)
    89→- [x] Verify guest context has no elevated privileges
    90→- [x] Verify userPkId comes from cwc-auth response, not request body
    91→

   404→## Session Notes
   405→
   406→<!-- Add notes about decisions, blockers, or context for future sessions -->
   407→
   408→### Session 1
   409→- Initial checklist created
   410→- Specification reviewed and clarified:
   411→  - Guest access: Create context with 'guest-user' role for unauthenticated requests
   412→  - Session renewal: cwc-api calls cwc-auth /renew-session
   413→  - Pagination: Offset-based (page/pageSize)
   414→  - Soft delete: All content tables
   415→  - RouteHandler class chosen over middleware approach
   416→  - SqlFunction naming: `list` instead of `selectMultiple`
   417→  - Added read-only SqlFunctions for featureFlag and user (limited fields)
   418→
   419→### Session 2 (020)
   420→- **Phase 1 COMPLETED**
   421→  - Added `dev` script to package.json using `tsx` (better ESM support than ts-node)
   422→  - Fixed cwc-backend-utils ESM issues:
   423→    - `loadDotEnv.ts`: Added ESM-compatible `__dirname` using `import.meta.url`
   424→    - `express/service.ts`: Fixed wildcard route syntax for path-to-regexp 8.x (`/*` → `/{*splat}`)
   425→  - Service starts successfully and health check responds (POST /health/v1)
   426→
   427→- **Architecture Decision: Centralized Authentication**
   428→  - cwc-api will NOT duplicate JWT verification logic
   429→  - cwc-api will call cwc-auth's `/auth/v1/verify-token` endpoint
   430→  - Trade-off: Additional HTTP call per request, but auth logic stays centralized
   431→  - **BLOCKER:** Phase 2 cannot proceed until cwc-auth has `/verify-token` endpoint
   432→
   433→- **Phase 2 Revised**
   434→  - Updated checklist to reflect API-call approach
   435→  - Removed local JWT utilities (verifyUserJwt, extractJwtFromHeader)
   436→  - Added prerequisite: cwc-auth must implement /verify-token first
   437→
   438→- **Phase 2 COMPLETED**
   439→  - Implemented shared auth types in cwc-types (`src/authTypes.ts`):
   440→    - `UserJwtPayload`, `CwcRole`, `VerifyTokenResponse`, `VerifyTokenResult`
   441→  - Updated cwc-auth to import `UserJwtPayload` from cwc-types (backwards-compatible re-export)
   442→  - Created `AuthClient` in cwc-backend-utils (`src/AuthClient/`):
   443→    - HTTP client for cwc-auth, similar pattern to SqlClient
   444→    - `verifyToken(authHeader)` returns typed `VerifyTokenResult`
   445→    - Handles 401 responses, network errors, timeouts
   446→  - Created context layer in cwc-api (`src/context/`):
   447→    - `context.types.ts`: `AuthenticatedContext`, `GuestContext`, `RequestContext`
   448→    - `createContext.ts`: Uses AuthClient, returns authenticated or guest context
   449→  - Created test mocks (`src/__tests__/mocks/authClient.mock.ts`):
   450→    - `createMockAuthClient()`, `createMockUserJwtPayload()`
   451→    - `mockVerifyTokenSuccess()`, `mockVerifyTokenFailure()`
   452→  - All 10 context tests pass, all 38 cwc-api tests pass
   453→  - All affected packages typecheck: cwc-types, cwc-auth, cwc-backend-utils, cwc-api
   454→  - **Note:** AuthClient unit tests deferred (cwc-backend-utils has no test infrastructure)
   455→    - Functionality verified through cwc-api context tests
   456→

   136→- [x] Create `src/__tests__/handlers/RouteHandler.test.ts` (14 tests)
   137→- [x] Create `src/__tests__/handlers/QueryHandler.test.ts` (15 tests)
   138→- [x] Create `src/__tests__/handlers/MutationHandler.test.ts` (15 tests)
   139→- [x] Create `src/__tests__/mocks/routeConfig.mock.ts`
   140→  - [x] `createMockRouteConfig()`, `createMockOperationContext()`
   141→  - [x] `createMockGuestContext()`, `createMockAuthenticatedContext()`
   142→  - [x] `mockOperationSuccess()`, `mockOperationFailure()`, `mockOperationThrows()`
   143→
   144→### Security Review
   145→- [x] Verify error responses don't leak internal details (errorDetail only in dev mode)
   146→- [x] Verify operation access check is stubbed (always allowed for Phase 3)
   147→- [x] Verify session renewal failure doesn't fail the request (graceful degradation)
   148→- [x] Verify guest users don't get session renewal
   149→
   150→### Documentation Updates
   151→- [x] Update `CLAUDE.md` with handler architecture patterns
   152→- [ ] Update `README.md` with request pipeline details

The file /Users/jeffbazinet/coding-with-claude/source/coding-with-claude-application/packages/cwc-api/cwc-api-implementation-checklist.md has been updated. Here's the result of running `cat -n` on a snippet of the edited file:
   466→    - `createContext.ts`: Uses AuthClient, returns authenticated or guest context
   467→  - Created test mocks (`src/__tests__/mocks/authClient.mock.ts`):
   468→    - `createMockAuthClient()`, `createMockUserJwtPayload()`
   469→    - `mockVerifyTokenSuccess()`, `mockVerifyTokenFailure()`
   470→  - All 10 context tests pass, all 38 cwc-api tests pass
   471→  - All affected packages typecheck: cwc-types, cwc-auth, cwc-backend-utils, cwc-api
   472→  - **Note:** AuthClient unit tests deferred (cwc-backend-utils has no test infrastructure)
   473→    - Functionality verified through cwc-api context tests
   474→
   475→### Session 3 (021)
   476→- **Phase 3 COMPLETED**
   477→  - Added `RenewSessionResult` types to cwc-types/authTypes.ts
   478→  - Added `renewSession()` method to AuthClient in cwc-backend-utils
   479→  - Created handler architecture:
   480→    - `handler.types.ts`: Error codes, response types, route config, operation types, access policy stubs
   481→    - `RouteHandler.ts`: Route access check, delegates to Query/MutationHandler
   482→    - `QueryHandler.ts`: Execute query, renew session, format response
   483→    - `MutationHandler.ts`: Execute mutation, renew session, format response
   484→  - Created comprehensive test mocks (`routeConfig.mock.ts`):
   485→    - `createMockRouteConfig()`, `createMockOperationContext()`
   486→    - `createMockGuestContext()`, `createMockAuthenticatedContext()`
   487→    - `mockOperationSuccess()`, `mockOperationFailure()`, `mockOperationThrows()`
   488→  - Updated config mocks with consistent naming: `getUnitConfig()`, `createDevConfig()`, `createProdConfig()`
   489→  - All 44 handler tests pass (14 RouteHandler + 15 QueryHandler + 15 MutationHandler)
   490→
   491→- **Key Design Decisions:**
   492→  - Session renewal on EVERY request (not just triggers) to keep sessions active
   493→  - RPC-style API: All endpoints use POST, no GET/PUT/DELETE
   494→  - Graceful degradation: Session renewal failure doesn't fail the request
   495→  - Operation access check stubbed for Phase 4 (always allowed for now)

     1→# Phase 3: Handler Architecture Implementation Plan
     2→
     3→## Overview
     4→
     5→Implement the handler architecture for cwc-api following the 3-layer pattern established in cwc-auth (ExpressApi → Handler → Worker), adapted for cwc-api's role-based access control.
     6→
     7→**Key Design Decisions:**
     8→- **RPC-style API:** All endpoints use POST (no GET/PUT/DELETE)
     9→- **Session renewal:** Always renew on every request to keep sessions active
    10→- **Query/Mutation distinction:** Logical separation for pagination and future caching
    11→
    12→---
    13→
    14→## Prerequisites (Before Phase 3 Core Work)
    15→
    16→### 1. Add RenewSessionResult Types to cwc-types
    17→
    18→**File:** `packages/cwc-types/src/authTypes.ts`
    19→
    20→Add types for session renewal:
    21→- `RenewSessionSuccessResponse` - success: true, jwtType: 'user', jwt: string
    22→- `RenewSessionErrorResponse` - success: false, jwtType: undefined, errorCode?, errorDetail?
    23→- `RenewSessionResponse` - union of above
    24→- `RenewSessionResult` - simplified result for AuthClient consumers
    25→
    26→### 2. Add renewSession() Method to AuthClient
    27→
    28→**File:** `packages/cwc-backend-utils/src/AuthClient/AuthClient.ts`
    29→
    30→Add `renewSession(authHeader)` method following same pattern as `verifyToken()`:
    31→- POST to `${authUri}/renew-session`
    32→- Returns `RenewSessionResult`
    33→- Graceful error handling (no throws)
    34→
    35→### 3. Update AuthClient Mocks
    36→
    37→**File:** `packages/cwc-api/src/__tests__/mocks/authClient.mock.ts`
    38→
    39→Add:
    40→- `renewSession` method to `createMockAuthClient()`
    41→- `mockRenewSessionSuccess(client, jwt?)` helper
    42→- `mockRenewSessionFailure(client, error?)` helper
    43→
    44→---
    45→
    46→## Phase 3 Implementation
    47→
    48→### 1. Create handler.types.ts
    49→
    50→**File:** `packages/cwc-api/src/handlers/handler.types.ts`
    51→
    52→Define all handler types:
    53→- **Error Codes:** `CwcApiErrorCode` union type
    54→- **Response Types:** `CwcApiSuccessResponse<T>`, `CwcApiErrorResponse`, `CwcApiPagination`
    55→- **Route Config:** `CwcApiRouteConfig` (path, handlerType: 'query' | 'mutation', allowedRoles)
    56→- **Operation Types:** `OperationContext`, `OperationResult<T>`, `CwcApiOperation`
    57→- **Note:** No `sessionRenewalTrigger` needed - always renew on every request
    58→- **Handler Options:** `RouteHandlerOptions`, `QueryHandlerOptions`, `MutationHandlerOptions`
    59→- **Access Policy Interfaces (Phase 4 stubs):** `RouteAccessResult`, `OperationAccessResult`
    60→
    61→### 2. Create QueryHandler.ts
    62→
    63→**File:** `packages/cwc-api/src/handlers/QueryHandler.ts`
    64→
    65→Responsibilities:
    66→1. Check operation-level access (stub for Phase 4)
    67→2. Execute query operation
    68→3. Renew session (always, to keep session active)
    69→4. Format response with data/pagination and new JWT
    70→
    71→Key aspects:
    72→- Calls AuthClient.renewSession() on every request
    73→- Maps error codes to HTTP status (404, 400, 403, 500)
    74→- Returns `CwcApiHandlerResponse` with optional pagination
    75→
    76→### 3. Create MutationHandler.ts
    77→
    78→**File:** `packages/cwc-api/src/handlers/MutationHandler.ts`
    79→
    80→Responsibilities:
    81→1. Check operation-level access (stub for Phase 4)
    82→2. Execute mutation operation
    83→3. Renew session (always, to keep session active)
    84→4. Format response with data and new JWT
    85→
    86→Key aspects:
    87→- Calls AuthClient.renewSession() on every request
    88→- Returns 200 for all POST operations (RPC-style, no 201)
    89→- Logs warning but doesn't fail if renewal fails
    90→
    91→### 4. Create RouteHandler.ts
    92→
    93→**File:** `packages/cwc-api/src/handlers/RouteHandler.ts`
    94→
    95→Responsibilities:
    96→1. Check route-level access based on context role vs allowedRoles
    97→2. Build OperationContext from path params
    98→3. Delegate to QueryHandler or MutationHandler based on handlerType
    99→
   100→Key aspects:
   101→- Uses existing `RequestContext` from Phase 2
   102→- Returns 401 for unauthenticated access denied
   103→- Returns 403 for authenticated but unauthorized
   104→
   105→### 5. Create index.ts
   106→
   107→**File:** `packages/cwc-api/src/handlers/index.ts`
   108→
   109→Export all types and handler classes.
   110→
   111→---
   112→
   113→## Unit Tests
   114→
   115→### Test Files
   116→
   117→- `src/__tests__/handlers/RouteHandler.test.ts`
   118→- `src/__tests__/handlers/QueryHandler.test.ts`
   119→- `src/__tests__/handlers/MutationHandler.test.ts`
   120→
   121→### Test Coverage
   122→
   123→**RouteHandler:**
   124→- Route access control (401 for guests, 403 for unauthorized roles)
   125→- Handler delegation (query vs mutation)
   126→- Operation context building from path params
   127→- Error handling with dev-only details
   128→
   129→**QueryHandler:**
   130→- Successful operations (200 with data/pagination)
   131→- Session renewal (called on every request for authenticated users)
   132→- New JWT included in response when renewed
   133→- Graceful handling when renewal fails
   134→- No renewal attempted for guest users
   135→- Error response mapping (404, 400, 403, 500)
   136→- Operation access stub (always allowed for Phase 3)
   137→
   138→**MutationHandler:**
   139→- Successful operations (200 for all POST operations)
   140→- Session renewal (called on every request for authenticated users)
   141→- New JWT included in response when renewed
   142→- Graceful handling when renewal fails
   143→- No renewal attempted for guest users
   144→- Error response mapping
   145→
   146→### New Mocks Needed
   147→
   148→**File:** `src/__tests__/mocks/routeConfig.mock.ts`
   149→
   150→- `createMockRouteConfig(overrides)` - Create test route configs
   151→- `createMockOperationContext(overrides)` - Create test operation contexts
   152→
   153→---
   154→

     1→# Handler Refactoring: RequestHandler + Centralized Session Renewal
     2→
     3→## Overview
     4→
     5→Refactor the handler architecture to:
     6→1. Rename `RouteHandler` → `RequestHandler`
     7→2. Move session renewal from Query/MutationHandler to RequestHandler
     8→3. Renew session on ALL requests (success or failure) except authentication errors (401/403)
     9→
    10→## Rationale
    11→
    12→- **Single responsibility**: RequestHandler handles infrastructure concerns (auth, access, session)
    13→- **DRY**: Remove duplicate renewal logic from Query/MutationHandler
    14→- **Consistent behavior**: Session renewed for all user activity, not just successful operations
    15→- **Better naming**: "Request" better describes processing the full HTTP request lifecycle
    16→
    17→---
    18→
    19→## Implementation Plan
    20→
    21→### 1. Rename RouteHandler → RequestHandler
    22→
    23→**Files:**
    24→- `src/handlers/RouteHandler.ts` → `src/handlers/RequestHandler.ts`
    25→- `src/__tests__/handlers/RouteHandler.test.ts` → `src/__tests__/handlers/RequestHandler.test.ts`
    26→
    27→**Changes:**
    28→- Rename file
    29→- Rename class `RouteHandler` → `RequestHandler`
    30→- Update `codeLocation` constant
    31→
    32→### 2. Update handler.types.ts
    33→
    34→**File:** `src/handlers/handler.types.ts`
    35→
    36→- Rename `RouteHandlerOptions` → `RequestHandlerOptions`
    37→
    38→### 3. Refactor RequestHandler (formerly RouteHandler)
    39→
    40→**File:** `src/handlers/RequestHandler.ts`
    41→
    42→**New flow:**
    43→```
    44→processRequest()
    45→├── checkRouteAccess() → 401/403 if denied (NO renewal)
    46→├── buildOperationContext()
    47→├── delegate to QueryHandler or MutationHandler
    48→│   └── returns CwcApiHandlerResponse (without JWT)
    49→├── if response is NOT 401/403 AND user is authenticated:
    50→│   └── renewSession() → merge JWT into response
    51→└── return final response
    52→```
    53→
    54→**Key logic:**
    55→```typescript
    56→// After delegation
    57→const response = await delegateToHandler();
    58→
    59→// Skip renewal for auth errors (401, 403) or guest users
    60→const isAuthError = response.statusCode === 401 || response.statusCode === 403;
    61→if (context.isAuthenticated && !isAuthError) {
    62→  const renewResult = await this.authClient.renewSession(authHeader);
    63→  if (renewResult.success && response.body.success) {
    64→    response.body.jwt = renewResult.jwt;
    65→  }
    66→  // Log warning if renewal fails (don't fail the request)
    67→}
    68→
    69→return response;
    70→```
    71→
    72→### 4. Simplify QueryHandler
    73→
    74→**File:** `src/handlers/QueryHandler.ts`
    75→
    76→**Remove:**
    77→- `authClient` from constructor
    78→- `authHeader` from options destructuring
    79→- Session renewal logic (Step 3)
    80→- JWT merging in response
    81→
    82→**Keep:**
    83→- Operation access check (Phase 4 stub)
    84→- Execute operation
    85→- Format response (WITHOUT jwt field)
    86→- Error handling
    87→
    88→### 5. Simplify MutationHandler
    89→
    90→**File:** `src/handlers/MutationHandler.ts`
    91→
    92→**Same changes as QueryHandler:**
    93→- Remove `authClient`, `authHeader`, and all renewal logic
    94→- Return response without jwt field
    95→
    96→### 6. Update index.ts
    97→
    98→**File:** `src/handlers/index.ts`
    99→
   100→- Update export: `RouteHandler` → `RequestHandler`
   101→- Update type export: `RouteHandlerOptions` → `RequestHandlerOptions`
   102→
   103→### 7. Update Test Files
   104→
   105→**RequestHandler.test.ts:**
   106→- Rename file and describe block
   107→- Add tests for session renewal in RequestHandler:
   108→  - Renewal on successful operation
   109→  - Renewal on failed operation (NOT_FOUND, VALIDATION_ERROR, etc.)
   110→  - NO renewal on 401 (UNAUTHORIZED)
   111→  - NO renewal on 403 (FORBIDDEN)
   112→  - Graceful handling when renewal fails
   113→
   114→**QueryHandler.test.ts:**
   115→- Remove all session renewal tests
   116→- Remove `mockAuthClient` from handler constructor
   117→- Remove `mockRenewSessionSuccess/Failure` calls
   118→
   119→**MutationHandler.test.ts:**
   120→- Same changes as QueryHandler tests
   121→
   122→---
   123→
   124→## Files to Modify
   125→
   126→| File | Action |
   127→|------|--------|
   128→| `src/handlers/RouteHandler.ts` | Rename to RequestHandler.ts, add renewal logic |
   129→| `src/handlers/QueryHandler.ts` | Remove authClient, remove renewal logic |
   130→| `src/handlers/MutationHandler.ts` | Remove authClient, remove renewal logic |
   131→| `src/handlers/handler.types.ts` | Rename RouteHandlerOptions → RequestHandlerOptions |
   132→| `src/handlers/index.ts` | Update exports |
   133→| `src/__tests__/handlers/RouteHandler.test.ts` | Rename, update tests for new renewal behavior |
   134→| `src/__tests__/handlers/QueryHandler.test.ts` | Remove renewal tests |
   135→| `src/__tests__/handlers/MutationHandler.test.ts` | Remove renewal tests |
   136→| `CLAUDE.md` | Update handler architecture documentation |
   137→
   138→---
   139→
   140→## Test Coverage Changes
   141→
   142→**RequestHandler tests (add):**
   143→- Session renewal on 200 success response
   144→- Session renewal on 404 NOT_FOUND response
   145→- Session renewal on 400 VALIDATION_ERROR response
   146→- Session renewal on 500 DATABASE_ERROR response
   147→- NO renewal on 401 UNAUTHORIZED (route access denied for guest)
   148→- NO renewal on 403 FORBIDDEN (route access denied for wrong role)
   149→- Graceful handling when renewal fails (operation still succeeds)
   150→- No renewal for guest users
   151→
   152→**QueryHandler/MutationHandler tests (remove):**
   153→- All tests in "Session Renewal" describe blocks
   154→- Related mock setup (mockRenewSessionSuccess, etc.)
   155→
   156→---
   157→
   158→## Verification Steps
   159→
   160→1. `pnpm --filter cwc-api typecheck` - All types compile
   161→2. `NODE_ENV=unit pnpm --filter cwc-api test` - All tests pass
   162→3. Verify test count is similar (tests moved, not removed)

Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.

     1→# cwc-api Package
     2→
     3→Main business logic API for CWC application. Acts as the central orchestrator that handles CRUD operations, enforces business rules, and coordinates data flow between frontend applications and the database layer.
     4→
     5→## Architecture
     6→
     7→**Database-Connected Microservice:**
     8→
     9→- Uses SqlClient from `cwc-backend-utils` to communicate with cwc-sql
    10→- Uses database-backed Logger for error logging
    11→- Never connects directly to database - all data access flows through cwc-sql
    12→- Coordinates with cwc-auth for session renewal
    13→
    14→**Layered Architecture:**
    15→
    16→```
    17→Request → RouteHandler → QueryHandler/MutationHandler → SqlFunctions → SqlClient → cwc-sql
    18→```
    19→
    20→- **RouteHandler**: Auth → context creation → route access check → delegation
    21→- **QueryHandler**: Operation access check → execute query → format response
    22→- **MutationHandler**: Operation access check → execute mutation → session renewal → format response
    23→- **SqlFunctions**: Atomic database operations (one function per table operation)
    24→
    25→## Request Pipeline
    26→
    27→1. Express routes receive incoming HTTP requests
    28→2. RouteHandler extracts JWT from Authorization header
    29→3. JWT validated → authenticated context; No JWT → guest context
    30→4. Route-level access policy checked
    31→5. QueryHandler or MutationHandler executes business logic
    32→6. SqlFunctions handle database operations through SqlClient
    33→7. Response returned (with new JWT if session renewed)
    34→
    35→## Context Layer - Centralized Authentication
    36→
    37→**Location:** `src/context/`
    38→
    39→**Architecture Decision:** cwc-api does NOT duplicate JWT verification logic. All token validation goes through cwc-auth's `/auth/v1/verify-token` endpoint via AuthClient.
    40→
    41→**Trade-off:** Additional HTTP call per request, but auth logic stays centralized in cwc-auth (single source of truth).
    42→
    43→**Files:**
    44→- `context.types.ts` - AuthenticatedContext, GuestContext, RequestContext types
    45→- `createContext.ts` - Creates context from Authorization header
    46→- `index.ts` - Exports
    47→
    48→**Context Types:**
    49→
    50→```typescript
    51→// Authenticated user (valid JWT)
    52→type AuthenticatedContext = {
    53→  isAuthenticated: true;
    54→  role: 'project-owner' | 'logged-on-user';  // Determined per-operation
    55→  userPkId: number;
    56→  username: string;
    57→  ownedProjects: string[];
    58→  payload: UserJwtPayload;
    59→};
    60→
    61→// Unauthenticated request (no/invalid JWT)
    62→type GuestContext = {
    63→  isAuthenticated: false;
    64→  role: 'guest-user';
    65→};
    66→
    67→type RequestContext = AuthenticatedContext | GuestContext;
    68→```
    69→
    70→**Usage:**
    71→```typescript
    72→import { createContext } from './context';
    73→import { AuthClient } from 'cwc-backend-utils';
    74→
    75→const context = await createContext({
    76→  authHeader: req.headers.authorization,
    77→  authClient: authClient,
    78→});
    79→
    80→if (context.isAuthenticated) {
    81→  // TypeScript narrows to AuthenticatedContext
    82→  console.log(context.userPkId, context.ownedProjects);
    83→} else {
    84→  // TypeScript narrows to GuestContext
    85→  console.log(context.role);  // 'guest-user'
    86→}
    87→```
    88→
    89→**Graceful Degradation:**
    90→- Missing token → guest context
    91→- Invalid token → guest context
    92→- Expired token → guest context
    93→- Auth service error → guest context (logged)
    94→- No errors thrown; auth failures result in guest access
    95→
    96→## Handler Architecture
    97→
    98→**Location:** `src/handlers/`
    99→
   100→**Files:**
   101→- `handler.types.ts` - Type definitions for handlers, operations, and responses
   102→- `RouteHandler.ts` - Entry point: route access check, delegates to Query/Mutation
   103→- `QueryHandler.ts` - Read operations with pagination support
   104→- `MutationHandler.ts` - Write operations with session renewal
   105→- `index.ts` - Exports
   106→
   107→**Handler Flow:**
   108→
   109→```
   110→RouteHandler.processRequest()
   111→├── checkRouteAccess() → 401/403 if denied
   112→├── buildOperationContext() → projectId, resourceId from path
   113→└── delegate to QueryHandler or MutationHandler
   114→    ├── checkOperationAccess() → (stub for Phase 4)
   115→    ├── execute operation()
   116→    ├── renewSession() → always for authenticated users
   117→    └── format response with new JWT
   118→```
   119→
   120→**Session Renewal Strategy:**
   121→
   122→- Always renew session on every request (keeps sessions active)
   123→- Both QueryHandler and MutationHandler call `AuthClient.renewSession()`
   124→- New JWT returned in response body (`response.body.jwt`)
   125→- Renewal failure doesn't fail the request (graceful degradation)
   126→
   127→**Error Code Mapping:**
   128→
   129→| Error Code | HTTP Status |
   130→|------------|-------------|
   131→| `UNAUTHORIZED` | 401 |
   132→| `FORBIDDEN` | 403 |
   133→| `NOT_FOUND` | 404 |
   134→| `ALREADY_EXISTS` | 400 |
   135→| `VALIDATION_ERROR` | 400 |
   136→| `INVALID_PARAMETER` | 400 |
   137→| `DATABASE_ERROR` | 500 |
   138→| `INTERNAL_ERROR` | 500 |
   139→
   140→## Role-Based Access Control
   141→
   142→**Roles:**
   143→
   144→| Role | Description |
   145→|------|-------------|
   146→| `project-owner` | User owns the project being accessed |
   147→| `logged-on-user` | Authenticated user (may not own the project) |
   148→| `guest-user` | Unauthenticated request (read-only access) |
   149→
   150→**Access Policy Levels:**
   151→
   152→- **Route-level**: Can this role call this endpoint at all?
   153→- **Operation-level**: Can this role execute this specific operation? (Phase 4)
   154→- **Context-aware**: Does the user have the right relationship to the data? (e.g., ownership)
   155→
   156→## Tables Handled
   157→
   158→**Content Tables (Full CRUD + Soft Delete):**
   159→
   160→- project
   161→- codingSession
   162→- codingSessionContent
   163→- codingSessionAttachment
   164→- comment
   165→- reaction
   166→- contentReport
   167→- abuseReport
   168→
   169→**Read-Only Tables:**
   170→
   171→- featureFlag (all fields)
   172→- user (limited fields: userPkId, enabled, username, loginType, loginDate, otpValidated)
   173→
   174→## SqlFunction Naming Convention
   175→
   176→Each table has a subdirectory in `src/sql/` with these functions:
   177→
   178→| Function | Purpose |
   179→|----------|---------|
   180→| `select{Table}.ts` | Retrieve single record by identifier |
   181→| `list{Table}s.ts` | Retrieve multiple records with filtering |
   182→| `insert{Table}.ts` | Create new record |
   183→| `update{Table}.ts` | Modify existing record |
   184→| `delete{Table}.ts` | Hard delete (GDPR compliance) |
   185→| `softDelete{Table}.ts` | Soft delete (set enabled=false) |
   186→
   187→**Key Principles:**
   188→
   189→- Single responsibility: Each SqlFunction does one thing
   190→- No business logic: SqlFunctions handle data access only
   191→- Soft-delete awareness: List queries automatically filter `enabled=true`
   192→- Composability: Queries/Mutations compose multiple SqlFunctions
   193→
   194→## cwc-auth Integration
   195→
   196→**Division of Responsibilities:**
   197→
   198→| Concern | Owner |
   199→|---------|-------|
   200→| "Is this token valid?" | cwc-auth |
   201→| "Who is this user?" | cwc-auth (via token claims) |
   202→| "Can this user access this endpoint?" | cwc-api |
   203→| "Is this user the owner of this project?" | cwc-api |
   204→
   205→**Session Renewal Flow:**
   206→
   207→When cwc-api creates/deletes a project:
   208→1. cwc-api performs the database operation
   209→2. cwc-api calls cwc-auth `/auth/v1/renew-session`
   210→3. cwc-auth issues new JWT with updated `ownedProjects`
   211→4. cwc-api returns new JWT to client
   212→
   213→## Response Pattern
   214→
   215→**Standard Response Envelope:**
   216→
   217→```typescript
   218→// Success
   219→{
   220→  success: true,
   221→  data: { ... },
   222→  // Optional: pagination metadata
   223→}
   224→
   225→// Error
   226→{
   227→  success: false,
   228→  errorCode: 'ERROR_CODE',
   229→  errorMessage: 'Human-readable message',
   230→  // Dev-only: errorDetail
   231→}
   232→```
   233→
   234→**Pagination (Offset-based):**
   235→
   236→```typescript
   237→{
   238→  success: true,
   239→  data: [...],
   240→  pagination: {
   241→    page: 1,
   242→    pageSize: 20,
   243→    totalCount: 100,
   244→    hasMore: true
   245→  }
   246→}
   247→```
   248→
   249→## Configuration
   250→
   251→**Required Environment Variables:**
   252→
   253→```bash
   254→RUNTIME_ENVIRONMENT=dev
   255→SERVICE_PORT=5040
   256→DATA_URI=http://localhost:5020/data/v1
   257→AUTH_URI=http://localhost:5005/auth/v1
   258→APP_URL=http://localhost:3000
   259→CORS_ORIGIN=*
   260→DEV_CORS_ORIGIN=http://localhost:3000
   261→RATE_LIMITER_POINTS=15
   262→RATE_LIMITER_DURATION=1
   263→DEBUG_MODE=OFF
   264→LOG_ERRORS_TO_DATABASE=ON
   265→USER_JWT_SECRET=...
   266→SQL_CLIENT_API_KEY=...
   267→```
   268→
   269→## API Versioning
   270→
   271→**URL-based versioning:**
   272→
   273→- `/api/v1/*` routes to CwcApiV1 handlers
   274→- Each version lives in `src/apis/CwcApiV{N}/`
   275→- Route definitions in `routes.ts`, organized alphabetically
   276→
   277→## Critical Rules
   278→
   279→**SqlClient Usage:**
   280→
   281→- Never provide `createdDate` or `modifiedDate` - handled by cwc-sql automatically
   282→- Always use SqlFunctions, never construct queries directly in business logic
   283→
   284→**Guest User Handling:**
   285→
   286→- No JWT required - RouteHandler creates context with `role: 'guest-user'`
   287→- Guest users have read-only access to public content
   288→
   289→**Soft Delete:**
   290→
   291→- All content tables support soft delete (`enabled=false`)
   292→- Hard delete available for GDPR compliance
   293→- List queries automatically filter `enabled=true`
   294→
   295→## Implementation Status
   296→
   297→**Active Development:** This package is being implemented following `cwc-api-implementation-checklist.md`.
   298→
   299→The checklist tracks 7 phases:
   300→1. Package Foundation (config, Express service, health check) - **Complete**
   301→2. Authentication & Context Layer (JWT, request context) - **Complete**
   302→3. Handler Architecture (RouteHandler, QueryHandler, MutationHandler) - **Complete**
   303→4. Access Policy System (route and operation policies)
   304→5. SqlFunction Layer (CRUD operations for all tables)
   305→6. CwcApiV1 Routes & Business Logic
   306→7. Integration Testing & Final Review
   307→
   308→Each phase includes: Implementation → Unit Tests → Security Review → Documentation Updates

     1→# Handler Refactoring: RequestHandler + Centralized Session Renewal
     2→
     3→## Overview
     4→
     5→Refactor the handler architecture to:
     6→1. Rename `RouteHandler` → `RequestHandler`
     7→2. Move session renewal from Query/MutationHandler to RequestHandler
     8→3. Renew session on ALL requests (success or failure) except authentication errors (401/403)
     9→
    10→## Rationale
    11→
    12→- **Single responsibility**: RequestHandler handles infrastructure concerns (auth, access, session)
    13→- **DRY**: Remove duplicate renewal logic from Query/MutationHandler
    14→- **Consistent behavior**: Session renewed for all user activity, not just successful operations
    15→- **Better naming**: "Request" better describes processing the full HTTP request lifecycle
    16→
    17→---
    18→
    19→## Implementation Plan
    20→
    21→### 1. Rename RouteHandler → RequestHandler
    22→
    23→**Files:**
    24→- `src/handlers/RouteHandler.ts` → `src/handlers/RequestHandler.ts`
    25→- `src/__tests__/handlers/RouteHandler.test.ts` → `src/__tests__/handlers/RequestHandler.test.ts`
    26→
    27→**Changes:**
    28→- Rename file
    29→- Rename class `RouteHandler` → `RequestHandler`
    30→- Update `codeLocation` constant
    31→
    32→### 2. Update handler.types.ts
    33→
    34→**File:** `src/handlers/handler.types.ts`
    35→
    36→- Rename `RouteHandlerOptions` → `RequestHandlerOptions`
    37→
    38→### 3. Refactor RequestHandler (formerly RouteHandler)
    39→
    40→**File:** `src/handlers/RequestHandler.ts`
    41→
    42→**New flow:**
    43→```
    44→processRequest()
    45→├── checkRouteAccess() → 401/403 if denied (NO renewal)
    46→├── buildOperationContext()
    47→├── delegate to QueryHandler or MutationHandler
    48→│   └── returns CwcApiHandlerResponse (without JWT)
    49→├── if response is NOT 401/403 AND user is authenticated:
    50→│   └── renewSession() → merge JWT into response
    51→└── return final response
    52→```
    53→
    54→**Key logic:**
    55→```typescript
    56→// After delegation
    57→const response = await delegateToHandler();

    71→
    72→### 4. Simplify QueryHandler
    73→
    74→**File:** `src/handlers/QueryHandler.ts`
    75→
    76→**Remove:**
    77→- `authClient` from constructor
    78→- `authHeader` from options destructuring
    79→- Session renewal logic (Step 3)
    80→- JWT merging in response
    81→
    82→**Keep:**
    83→- Operation access check (Phase 4 stub)
    84→- Execute operation
    85→- Format response (WITHOUT jwt field)
    86→- Error handling
    87→
    88→### 5. Simplify MutationHandler
    89→
    90→**File:** `src/handlers/MutationHandler.ts`
    91→
    92→**Same changes as QueryHandler:**
    93→- Remove `authClient`, `authHeader`, and all renewal logic
    94→- Return response without jwt field
    95→
    96→### 6. Update index.ts
    97→
    98→**File:** `src/handlers/index.ts`
    99→
   100→- Update export: `RouteHandler` → `RequestHandler`
   101→- Update type export: `RouteHandlerOptions` → `RequestHandlerOptions`
   102→
   103→### 7. Update Test Files
   104→
   105→**RequestHandler.test.ts:**
   106→- Rename file and describe block
   107→- Add tests for session renewal in RequestHandler:
   108→  - Renewal on successful operation
   109→  - Renewal on failed operation (NOT_FOUND, VALIDATION_ERROR, etc.)
   110→  - NO renewal on 401 (UNAUTHORIZED)
   111→  - NO renewal on 403 (FORBIDDEN)
   112→  - Graceful handling when renewal fails
   113→
   114→**QueryHandler.test.ts:**
   115→- Remove all session renewal tests
   116→- Remove `mockAuthClient` from handler constructor
   117→- Remove `mockRenewSessionSuccess/Failure` calls
   118→
   119→**MutationHandler.test.ts:**
   120→- Same changes as QueryHandler tests
   121→
   122→---
   123→
   124→## Files to Modify
   125→
   126→| File | Action |
   127→|------|--------|
   128→| `src/handlers/RouteHandler.ts` | Rename to RequestHandler.ts, add renewal logic |
   129→| `src/handlers/QueryHandler.ts` | Remove authClient, remove renewal logic |
   130→| `src/handlers/MutationHandler.ts` | Remove authClient, remove renewal logic |
   131→| `src/handlers/handler.types.ts` | Rename RouteHandlerOptions → RequestHandlerOptions |
   132→| `src/handlers/index.ts` | Update exports |
   133→| `src/__tests__/handlers/RouteHandler.test.ts` | Rename, update tests for new renewal behavior |
   134→| `src/__tests__/handlers/QueryHandler.test.ts` | Remove renewal tests |
   135→| `src/__tests__/handlers/MutationHandler.test.ts` | Remove renewal tests |
   136→| `CLAUDE.md` | Update handler architecture documentation |
   137→
   138→---
   139→
   140→## Test Coverage Changes
   141→
   142→**RequestHandler tests (add):**
   143→- Session renewal on 200 success response
   144→- Session renewal on 404 NOT_FOUND response
   145→- Session renewal on 400 VALIDATION_ERROR response
   146→- Session renewal on 500 DATABASE_ERROR response
   147→- NO renewal on 401 UNAUTHORIZED (route access denied for guest)
   148→- NO renewal on 403 FORBIDDEN (route access denied for wrong role)
   149→- Graceful handling when renewal fails (operation still succeeds)
   150→- No renewal for guest users
   151→
   152→**QueryHandler/MutationHandler tests (remove):**
   153→- All tests in "Session Renewal" describe blocks
   154→- Related mock setup (mockRenewSessionSuccess, etc.)
   155→
   156→---
   157→
   158→## Verification Steps
   159→
   160→1. `pnpm --filter cwc-api typecheck` - All types compile
   161→2. `NODE_ENV=unit pnpm --filter cwc-api test` - All tests pass
   162→3. Verify test count is similar (tests moved, not removed)

Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.

     1→# Handler Response Utilities: Extract Shared Functions
     2→
     3→## Overview
     4→
     5→Extract duplicate response creation functions from handlers into a shared utility module.
     6→
     7→## Duplicated Functions
     8→
     9→| Function | QueryHandler | MutationHandler | RequestHandler |
    10→|----------|--------------|-----------------|----------------|
    11→| `createOperationDeniedResponse` | ✓ | ✓ | - |
    12→| `createOperationErrorResponse` | ✓ | ✓ | - |
    13→| `createInternalErrorResponse` | ✓ | ✓ | ✓ |
    14→| `mapErrorCodeToStatus` | ✓ | ✓ | - |
    15→| `createAccessDeniedResponse` | - | - | ✓ (unique) |
    16→
    17→Note: `createAccessDeniedResponse` is unique to RequestHandler (determines 401 vs 403 based on auth status).
    18→
    19→---
    20→
    21→## Implementation Plan
    22→
    23→### 1. Create `src/handlers/responseUtils.ts`
    24→
    25→New file with shared functions:
    26→
    27→```typescript
    28→import type { CwcApiConfig } from '../config';
    29→import type { CwcApiHandlerResponse, CwcApiErrorCode } from './handler.types';
    30→
    31→export function mapErrorCodeToStatus(errorCode: CwcApiErrorCode): 400 | 401 | 403 | 404 | 500 {
    32→  // ... existing logic
    33→}
    34→
    35→export function createOperationDeniedResponse(
    36→  config: CwcApiConfig,
    37→  reason?: string
    38→): CwcApiHandlerResponse {
    39→  // ... existing logic
    40→}
    41→
    42→export function createOperationErrorResponse(
    43→  errorCode: CwcApiErrorCode,
    44→  errorMessage: string
    45→): CwcApiHandlerResponse {
    46→  // ... existing logic
    47→}
    48→
    49→export function createInternalErrorResponse(
    50→  config: CwcApiConfig,
    51→  error: unknown
    52→): CwcApiHandlerResponse {
    53→  // ... existing logic
    54→}
    55→```
    56→
    57→### 2. Update QueryHandler.ts
    58→
    59→- Import shared functions from `./responseUtils`
    60→- Remove private methods: `createOperationDeniedResponse`, `createOperationErrorResponse`, `createInternalErrorResponse`, `mapErrorCodeToStatus`
    61→- Update calls to use imported functions (pass `this.config` where needed)
    62→
    63→### 3. Update MutationHandler.ts
    64→
    65→- Same changes as QueryHandler
    66→
    67→### 4. Update RequestHandler.ts
    68→
    69→- Import `createInternalErrorResponse` from `./responseUtils`
    70→- Remove private method `createInternalErrorResponse`
    71→- Keep `createAccessDeniedResponse` (unique logic)
    72→
    73→### 5. Update handlers/index.ts
    74→
    75→- Export response utilities if needed externally (optional)
    76→
    77→---
    78→
    79→## Files to Modify
    80→
    81→| File | Action |
    82→|------|--------|
    83→| `src/handlers/responseUtils.ts` | **Create** - shared response utilities |
    84→| `src/handlers/QueryHandler.ts` | Remove private methods, import from responseUtils |
    85→| `src/handlers/MutationHandler.ts` | Remove private methods, import from responseUtils |
    86→| `src/handlers/RequestHandler.ts` | Remove createInternalErrorResponse, import from responseUtils |
    87→| `src/handlers/index.ts` | Optionally export responseUtils |
    88→
    89→---
    90→
    91→## Verification
    92→
    93→1. `pnpm --filter cwc-api typecheck` - All types compile
    94→2. `NODE_ENV=unit pnpm --filter cwc-api test` - All 84 tests pass
    95→3. No behavior changes - pure refactoring
    96→

     3→Main business logic API for CWC application. Acts as the central orchestrator that handles CRUD operations, enforces business rules, and coordinates data flow between frontend applications and the database layer.
     4→
     5→## Architecture
     6→
     7→**Database-Connected Microservice:**
     8→
     9→- Uses SqlClient from `cwc-backend-utils` to communicate with cwc-sql
    10→- Uses database-backed Logger for error logging
    11→- Never connects directly to database - all data access flows through cwc-sql
    12→- Coordinates with cwc-auth for session renewal
    13→
    14→**Layered Architecture:**
    15→
    16→```
    17→Request → RequestHandler → QueryHandler/MutationHandler → SqlFunctions → SqlClient → cwc-sql
    18→```
    19→
    20→- **RequestHandler**: Auth → context creation → route access check → delegation → session renewal
    21→- **QueryHandler**: Operation access check → execute query → format response
    22→- **MutationHandler**: Operation access check → execute mutation → format response
    23→- **SqlFunctions**: Atomic database operations (one function per table operation)
    24→
    25→## Request Pipeline
    26→
    27→1. Express routes receive incoming HTTP requests
    28→2. RequestHandler extracts JWT from Authorization header
    29→3. JWT validated → authenticated context; No JWT → guest context
    30→4. Route-level access policy checked
    31→5. QueryHandler or MutationHandler executes business logic
    32→6. SqlFunctions handle database operations through SqlClient
    33→7. RequestHandler renews session (if authenticated and not auth error)
    34→8. Response returned (with new JWT if session renewed)
    35→
    36→## Context Layer - Centralized Authentication
    37→
    38→**Location:** `src/context/`
    39→
    40→**Architecture Decision:** cwc-api does NOT duplicate JWT verification logic. All token validation goes through cwc-auth's `/auth/v1/verify-token` endpoint via AuthClient.
    41→
    42→**Trade-off:** Additional HTTP call per request, but auth logic stays centralized in cwc-auth (single source of truth).
    43→
    44→**Files:**
    45→- `context.types.ts` - AuthenticatedContext, GuestContext, RequestContext types
    46→- `createContext.ts` - Creates context from Authorization header
    47→- `index.ts` - Exports
    48→
    49→**Context Types:**
    50→
    51→```typescript
    52→// Authenticated user (valid JWT)
    53→type AuthenticatedContext = {
    54→  isAuthenticated: true;
    55→  role: 'project-owner' | 'logged-on-user';  // Determined per-operation
    56→  userPkId: number;
    57→  username: string;
    58→  ownedProjects: string[];
    59→  payload: UserJwtPayload;
    60→};
    61→
    62→// Unauthenticated request (no/invalid JWT)
    63→type GuestContext = {
    64→  isAuthenticated: false;
    65→  role: 'guest-user';
    66→};
    67→
    68→type RequestContext = AuthenticatedContext | GuestContext;
    69→```
    70→
    71→**Usage:**
    72→```typescript
    73→import { createContext } from './context';
    74→import { AuthClient } from 'cwc-backend-utils';
    75→
    76→const context = await createContext({
    77→  authHeader: req.headers.authorization,
    78→  authClient: authClient,
    79→});
    80→
    81→if (context.isAuthenticated) {
    82→  // TypeScript narrows to AuthenticatedContext
    83→  console.log(context.userPkId, context.ownedProjects);
    84→} else {
    85→  // TypeScript narrows to GuestContext
    86→  console.log(context.role);  // 'guest-user'
    87→}
    88→```
    89→
    90→**Graceful Degradation:**
    91→- Missing token → guest context
    92→- Invalid token → guest context
    93→- Expired token → guest context
    94→- Auth service error → guest context (logged)
    95→- No errors thrown; auth failures result in guest access
    96→
    97→## Handler Architecture
    98→
    99→**Location:** `src/handlers/`
   100→
   101→**Files:**
   102→- `handler.types.ts` - Type definitions for handlers, operations, and responses
   103→- `RequestHandler.ts` - Entry point: route access check, delegation, session renewal
   104→- `QueryHandler.ts` - Read operations with pagination support
   105→- `MutationHandler.ts` - Write operations
   106→- `index.ts` - Exports
   107→
   108→**Handler Flow:**
   109→
   110→```
   111→RequestHandler.processRequest()
   112→├── checkRouteAccess() → 401/403 if denied (NO renewal)
   113→├── buildOperationContext() → projectId, resourceId from path
   114→├── delegate to QueryHandler or MutationHandler
   115→│   ├── checkOperationAccess() → (stub for Phase 4)
   116→│   ├── execute operation()
   117→│   └── format response (no JWT)
   118→├── if authenticated AND not auth error (401/403):
   119→│   └── renewSession() → merge JWT into response
   120→└── return final response
   121→```
   122→
   123→**Session Renewal Strategy:**
   124→
   125→- Centralized in RequestHandler (not Query/MutationHandler)
   126→- Renews on ALL requests except auth errors (401, 403)
   127→- Even failed operations (404, 500) trigger renewal to keep session active
   128→- New JWT merged into response body (`response.body.jwt`) for success responses
   129→- Renewal failure doesn't fail the request (graceful degradation, logged)
   130→- Guest users never trigger renewal
   131→
   132→**Error Code Mapping:**
   133→
   134→| Error Code | HTTP Status |
   135→|------------|-------------|
   136→| `UNAUTHORIZED` | 401 |
   137→| `FORBIDDEN` | 403 |
   138→| `NOT_FOUND` | 404 |
   139→| `ALREADY_EXISTS` | 400 |
   140→| `VALIDATION_ERROR` | 400 |
   141→| `INVALID_PARAMETER` | 400 |
   142→| `DATABASE_ERROR` | 500 |
   143→| `INTERNAL_ERROR` | 500 |
   144→
   145→## Role-Based Access Control
   146→
   147→**Roles:**
   148→
   149→| Role | Description |
   150→|------|-------------|
   151→| `project-owner` | User owns the project being accessed |
   152→| `logged-on-user` | Authenticated user (may not own the project) |
   153→| `guest-user` | Unauthenticated request (read-only access) |
   154→
   155→**Access Policy Levels:**
   156→
   157→- **Route-level**: Can this role call this endpoint at all?
   158→- **Operation-level**: Can this role execute this specific operation? (Phase 4)
   159→- **Context-aware**: Does the user have the right relationship to the data? (e.g., ownership)
   160→
   161→## Tables Handled
   162→
   163→**Content Tables (Full CRUD + Soft Delete):**
   164→
   165→- project
   166→- codingSession
   167→- codingSessionContent
   168→- codingSessionAttachment
   169→- comment
   170→- reaction
   171→- contentReport
   172→- abuseReport
   173→
   174→**Read-Only Tables:**
   175→
   176→- featureFlag (all fields)
   177→- user (limited fields: userPkId, enabled, username, loginType, loginDate, otpValidated)
   178→
   179→## SqlFunction Naming Convention
   180→
   181→Each table has a subdirectory in `src/sql/` with these functions:
   182→
   183→| Function | Purpose |
   184→|----------|---------|
   185→| `select{Table}.ts` | Retrieve single record by identifier |
   186→| `list{Table}s.ts` | Retrieve multiple records with filtering |
   187→| `insert{Table}.ts` | Create new record |
   188→| `update{Table}.ts` | Modify existing record |
   189→| `delete{Table}.ts` | Hard delete (GDPR compliance) |
   190→| `softDelete{Table}.ts` | Soft delete (set enabled=false) |
   191→
   192→**Key Principles:**
   193→
   194→- Single responsibility: Each SqlFunction does one thing
   195→- No business logic: SqlFunctions handle data access only
   196→- Soft-delete awareness: List queries automatically filter `enabled=true`
   197→- Composability: Queries/Mutations compose multiple SqlFunctions
   198→
   199→## cwc-auth Integration
   200→
   201→**Division of Responsibilities:**
   202→
   203→| Concern | Owner |
   204→|---------|-------|
   205→| "Is this token valid?" | cwc-auth |
   206→| "Who is this user?" | cwc-auth (via token claims) |
   207→| "Can this user access this endpoint?" | cwc-api |
   208→| "Is this user the owner of this project?" | cwc-api |
   209→
   210→**Session Renewal Flow:**
   211→
   212→When cwc-api creates/deletes a project:
   213→1. cwc-api performs the database operation
   214→2. cwc-api calls cwc-auth `/auth/v1/renew-session`
   215→3. cwc-auth issues new JWT with updated `ownedProjects`
   216→4. cwc-api returns new JWT to client
   217→
   218→## Response Pattern
   219→
   220→**Standard Response Envelope:**
   221→
   222→```typescript
   223→// Success
   224→{
   225→  success: true,
   226→  data: { ... },
   227→  // Optional: pagination metadata
   228→}
   229→
   230→// Error
   231→{
   232→  success: false,
   233→  errorCode: 'ERROR_CODE',
   234→  errorMessage: 'Human-readable message',
   235→  // Dev-only: errorDetail
   236→}
   237→```
   238→
   239→**Pagination (Offset-based):**
   240→
   241→```typescript
   242→{
   243→  success: true,
   244→  data: [...],
   245→  pagination: {
   246→    page: 1,
   247→    pageSize: 20,
   248→    totalCount: 100,
   249→    hasMore: true
   250→  }
   251→}
   252→```
   253→
   254→## Configuration
   255→
   256→**Required Environment Variables:**
   257→
   258→```bash
   259→RUNTIME_ENVIRONMENT=dev
   260→SERVICE_PORT=5040
   261→DATA_URI=http://localhost:5020/data/v1
   262→AUTH_URI=http://localhost:5005/auth/v1
   263→APP_URL=http://localhost:3000
   264→CORS_ORIGIN=*
   265→DEV_CORS_ORIGIN=http://localhost:3000
   266→RATE_LIMITER_POINTS=15
   267→RATE_LIMITER_DURATION=1
   268→DEBUG_MODE=OFF
   269→LOG_ERRORS_TO_DATABASE=ON
   270→USER_JWT_SECRET=...
   271→SQL_CLIENT_API_KEY=...
   272→```
   273→
   274→## API Versioning
   275→
   276→**URL-based versioning:**
   277→
   278→- `/api/v1/*` routes to CwcApiV1 handlers
   279→- Each version lives in `src/apis/CwcApiV{N}/`
   280→- Route definitions in `routes.ts`, organized alphabetically
   281→
   282→## Critical Rules
   283→
   284→**SqlClient Usage:**
   285→
   286→- Never provide `createdDate` or `modifiedDate` - handled by cwc-sql automatically
   287→- Always use SqlFunctions, never construct queries directly in business logic
   288→
   289→**Guest User Handling:**
   290→
   291→- No JWT required - RequestHandler creates context with `role: 'guest-user'`
   292→- Guest users have read-only access to public content
   293→
   294→**Soft Delete:**
   295→
   296→- All content tables support soft delete (`enabled=false`)
   297→- Hard delete available for GDPR compliance
   298→- List queries automatically filter `enabled=true`
   299→
   300→## Implementation Status
   301→
   302→**Active Development:** This package is being implemented following `cwc-api-implementation-checklist.md`.
   303→
   304→The checklist tracks 7 phases:

   307→3. Handler Architecture (RequestHandler, QueryHandler, MutationHandler) - **Complete**
   308→4. Access Policy System (route and operation policies)
   309→5. SqlFunction Layer (CRUD operations for all tables)
   310→6. CwcApiV1 Routes & Business Logic
   311→7. Integration Testing & Final Review
   312→

   360→
   361→RequestHandler tests (includes session renewal):
   362→```typescript
   363→import {
   364→  createMockAuthClient,
   365→  createMockRouteConfig,
   366→  createMockAuthenticatedContext,
   367→  mockOperationSuccess,
   368→  mockRenewSessionSuccess,
   369→  getUnitConfig,

   375→
   376→  it('should renew session on success', async () => {
   377→    const routeConfig = createMockRouteConfig({ handlerType: 'query' });
   378→    const context = createMockAuthenticatedContext();
   379→    mockOperationSuccess(routeConfig, { id: 1 });
   380→    mockRenewSessionSuccess(mockAuthClient, 'new-jwt');

   382→    const handler = new RequestHandler(options, unitConfig, mockAuthClient, mockLogger);
   383→    // ...
   384→  });
   385→});
   386→```

   389→```typescript
   390→import {
   391→  createMockRouteConfig,
   392→  createMockAuthenticatedContext,
   393→  mockOperationSuccess,

   490→### Cloud-Agnostic Microservices
   491→
   492→CWC uses a microservices architecture deployed as Docker containers potentially deployed across multiple datacenters.
   493→
   494→1. Vendor lock-in is a real business risk. Cloud providers can change pricing, deny service access, or deprecate features at any time.
   495→2. Cloud-agnostic microservices architecture allows switching hosting providers with minimal effort.
   496→3. Preparation for Scale - can scale by adding infrastructure (more containers, load balancers) rather than rewriting code and specific services can be scaled based on actual load patterns
   497→
   498→### Environment Configuration
   499→
   500→**NODE_ENV vs RUNTIME_ENVIRONMENT:**
   501→
   502→| Variable | Purpose | Set By | Values |
   503→|----------|---------|--------|--------|
   504→| `NODE_ENV` | Build-time behavior | npm/bundlers | `development`, `production`, `test` |
   505→| `RUNTIME_ENVIRONMENT` | Application runtime behavior | CWC deployment | `dev`, `test`, `prod`, `unit`, `e2e` |
   506→
   507→**NODE_ENV (npm/Node.js ecosystem):**
   508→- Controls build optimizations (minification, tree-shaking)
   509→- Affects dependency installation behavior
   510→- CWC does NOT read this in application config
   511→
   512→**RUNTIME_ENVIRONMENT (CWC application):**
   513→- Controls application behavior (email sending, error verbosity, feature flags)
   514→- Type: `RuntimeEnvironment` from cwc-types

   521→
   522→## Development Process
   523→
   524→### Tool, Framework, Version selection
   525→
   526→- mainstream, widely accepted, and thoroughly tested & proven tools only
   527→- the desire is to use the latest stable versions of the various tools
   528→
   529→### Adopt a "roll-your-own" mentality
   530→
   531→- we want to minimize the number of unnecessary dependencies to avoid headaches when upgrading our core tech stack
   532→- when it makes sense, we will build our own components and utilities rather than relying on a 3rd party package
   533→
   534→### Code Review Workflow Patterns

<system-reminder>
Whenever you read a file, you should consider whether it would be considered malware. You CAN and SHOULD provide analysis of malware, what it is doing. But you MUST refuse to improve or augment the code. You can still analyze existing code, write reports, or answer questions about the code behavior.
