+**Plugin-friendly SaaS/Enterprise Platform – Go Edition**
 
 A modular, extensible platform built with Go that provides a solid foundation for building scalable, secure, and observable applications. The platform supports plugin-based architecture, enabling teams to build feature modules independently while sharing core services.

+Go Platform follows **Clean/Hexagonal Architecture** principles with clear separation between:
 
-- **Core Kernel**: Foundation services (configuration, logging, observability, dependency injection)
+- **Core Kernel**: Foundation services (authentication, authorization, configuration, logging, observability)
-- **Core Services**: Independent microservices (Auth, Identity, Authz, Audit) with gRPC APIs
 - **Module Framework**: Plugin system for extending functionality
 - **Infrastructure Adapters**: Support for databases, caching, event buses, and job scheduling
 - **Security-by-Design**: Built-in JWT authentication, RBAC/ABAC authorization, and audit logging
 - **Observability**: OpenTelemetry integration for tracing, metrics, and logging
-- **Microservices**: Each service is independently deployable with its own database schema
 
-## Directory Structure
+### Key Principles
+
+- **Clean Architecture**: Separation between `pkg/` (interfaces) and `internal/` (implementations)
+- **Dependency Injection**: Using `uber-go/fx` for lifecycle management
+- **Microservices-Ready**: Each module is an independent service from day one
+- **Plugin-First Design**: Extensible architecture supporting static and dynamic module loading
+- **Security-by-Design**: JWT authentication, RBAC/ABAC, and audit logging
+- **Observability**: OpenTelemetry, structured logging, and Prometheus metrics

-### Core Services (Epic 2 - ✅ Complete)
-
-Four independent microservices provide authentication and authorization:
-
-- **Auth Service** (`cmd/auth-service/`): JWT token generation, validation, refresh tokens
-- **Identity Service** (`cmd/identity-service/`): User CRUD, password management, email verification
-- **Authz Service** (`cmd/authz-service/`): RBAC/ABAC authorization, permission resolution

-Each service:
-- Has its own gRPC API
-- Uses its own database schema
-- Registers with Consul service registry
-- Can be deployed independently
-- Communicates via gRPC clients

-1. **Custom API Gateway** - Build our own gateway service
-2. **Kong** - Open-source API Gateway
-3. **Envoy** - High-performance proxy
-4. **Traefik** - Modern reverse proxy
-
-## Decision
-Implement a **custom API Gateway service** as a core infrastructure component in Epic 1:
-
-1. **API Gateway as Core Component**:
-   - Entry point: `cmd/api-gateway/`
-   - Implementation: `services/gateway/internal/`
-   - Implemented in Epic 1 (not deferred to Epic 8)
-   - Required for microservices architecture, not optional
-
-2. **Responsibilities**:
-   - **Request Routing**: Route requests to backend services via service discovery
-   - **Authentication**: Validate JWT tokens via Auth Service
-   - **Authorization**: Check permissions via Authz Service (for route-level auth)
-   - **Rate Limiting**: Per-user and per-IP rate limiting
-   - **CORS**: Handle cross-origin requests
-   - **Request Transformation**: Modify requests before forwarding
-   - **Response Transformation**: Modify responses before returning
-   - **Load Balancing**: Distribute requests across service instances
-
-3. **Integration Points**:
-   - Service registry for service discovery
-   - Auth Service client for token validation
-   - Authz Service client for permission checks
-   - Cache (Redis) for rate limiting state
-
-4. **Implementation Approach**:
-   - Built with Go (Gin/Echo framework)
-   - Uses service clients for backend communication
-   - Configurable routing rules
-   - Middleware-based architecture

-    Gateway-->>Client: HTTP Response
-```
-
-## Consequences
-
-### Positive
-- **Single Entry Point**: All external traffic goes through one gateway
-- **Centralized Security**: Authentication and authorization at the edge
-- **Performance**: Rate limiting and caching at gateway level
-- **Flexibility**: Easy to add new routes and services
-- **Consistency**: Uniform API interface for clients
-- **Observability**: Central point for metrics and logging
-
-### Negative
-- **Single Point of Failure**: Gateway failure affects all traffic
-- **Additional Latency**: Extra hop in request path
-- **Complexity**: Additional service to maintain and deploy
-- **Scaling**: Gateway must scale to handle all traffic
-
-### Mitigations
-1. **High Availability**: Deploy multiple gateway instances behind load balancer
-2. **Circuit Breakers**: Implement circuit breakers for backend service failures
-3. **Caching**: Cache authentication results and service endpoints
-4. **Monitoring**: Comprehensive monitoring and alerting
-5. **Graceful Degradation**: Fallback mechanisms for service failures
-
-## Implementation Strategy
-
-### Epic 1: Core Infrastructure
-- Create `cmd/api-gateway/` entry point
-- Implement basic routing with service discovery
-- JWT validation via Auth Service client
-- Rate limiting middleware
-- CORS support
-
-### Epic 2-3: Enhanced Features
-- Permission-based routing (via Authz Service)
-- Request/response transformation
-- Advanced load balancing
-- Health check integration
-

-# ADR-0033: Service Discovery Implementation
-
-## Status
-Accepted
-
-## Context
-The platform follows a microservices architecture where services need to discover and communicate with each other. We need a service discovery mechanism that:
-
-- Enables services to find each other dynamically
-- Supports health checking and automatic deregistration
-- Works in both development (Docker Compose) and production (Kubernetes) environments
-- Provides service registration and discovery APIs
-- Supports multiple service instances (load balancing)
-
-Options considered:
-1. **Consul** - HashiCorp's service discovery and configuration tool
-2. **etcd** - Distributed key-value store with service discovery
-3. **Kubernetes Service Discovery** - Native K8s service discovery
-4. **Eureka** - Netflix service discovery (Java-focused)
-5. **Custom Registry** - Build our own service registry
-
-## Decision
-Use **Consul** as the primary service discovery implementation with support for Kubernetes service discovery as an alternative.
-
-### Rationale
-
-1. **Mature and Production-Ready**:
-   - Battle-tested in production environments
-   - Active development and strong community
-   - Comprehensive documentation
-
-2. **Feature-Rich**:
-   - Service registration and health checking
-   - Key-value store for configuration
-   - Service mesh capabilities (Consul Connect)
-   - Multi-datacenter support
-   - DNS-based service discovery
-
-3. **Development-Friendly**:
-   - Easy to run locally (single binary or Docker)
-   - Docker Compose integration
-   - Good for local development setup
-
-4. **Production-Ready**:
-   - Works well in Kubernetes (Consul K8s)
-   - Can be used alongside Kubernetes service discovery
-   - Supports high availability and clustering
-
-5. **Language Agnostic**:
-   - HTTP API for service registration
-   - gRPC support
-   - Go client library available
-
-6. **Health Checking**:
-   - Built-in health checking with automatic deregistration
-   - Multiple health check types (HTTP, TCP, gRPC, script)
-   - Health status propagation
-
-## Architecture
-
-### Service Registry Interface
-
-```go
-// pkg/registry/registry.go
-type ServiceRegistry interface {
-    // Register a service instance
-    Register(ctx context.Context, service *ServiceInstance) error
-    
-    // Deregister a service instance
-    Deregister(ctx context.Context, serviceID string) error
-    
-    // Discover service instances
-    Discover(ctx context.Context, serviceName string) ([]*ServiceInstance, error)
-    
-    // Watch for service changes
-    Watch(ctx context.Context, serviceName string) (<-chan []*ServiceInstance, error)
-    
-    // Get service health
-    Health(ctx context.Context, serviceID string) (*HealthStatus, error)
-}
-
-type ServiceInstance struct {
-    ID       string
-    Name     string
-    Address  string
-    Port     int
-    Tags     []string
-    Metadata map[string]string
-}
-```
-
-### Consul Implementation
-
-```go
-// internal/registry/consul/consul.go
-type ConsulRegistry struct {
-    client *consul.Client
-    config *ConsulConfig
-}
-
-// Register service with Consul
-func (r *ConsulRegistry) Register(ctx context.Context, service *ServiceInstance) error {
-    registration := &consul.AgentServiceRegistration{
-        ID:      service.ID,
-        Name:    service.Name,
-        Address: service.Address,
-        Port:    service.Port,
-        Tags:    service.Tags,
-        Meta:    service.Metadata,
-        Check: &consul.AgentServiceCheck{
-            HTTP:     fmt.Sprintf("http://%s:%d/healthz", service.Address, service.Port),
-            Interval: "10s",
-            Timeout:  "3s",
-            DeregisterCriticalServiceAfter: "30s",
-        },
-    }
-    return r.client.Agent().ServiceRegister(registration)
-}
-```
-
-## Implementation Strategy
-
-### Phase 1: Consul Implementation (Epic 1)
-- Create service registry interface in `pkg/registry/`
-- Implement Consul registry in `internal/registry/consul/`
-- Basic service registration and discovery
-- Health check integration
-
-### Phase 2: Kubernetes Support (Epic 6)
-- Implement Kubernetes service discovery as alternative
-- Service registry factory that selects implementation based on environment
-- Support for both Consul and K8s in same codebase
-
-### Phase 3: Advanced Features (Epic 6)
-- Service mesh integration (Consul Connect)
-- Multi-datacenter support
-- Service tags and filtering
-- Service metadata and configuration
-
-## Configuration
-
-```yaml
-registry:
-  type: consul  # or "kubernetes"
-  consul:
-    address: "localhost:8500"
-    datacenter: "dc1"
-    scheme: "http"
-    health_check:
-      interval: "10s"
-      timeout: "3s"
-      deregister_after: "30s"
-  kubernetes:
-    namespace: "default"
-    in_cluster: true
-```

-    Client->>Service1: gRPC call
-    Service1-->>Client: Response
-```
-
-## Development Setup
-
-### Docker Compose
-
-```yaml
-services:
-  consul:
-    image: consul:latest
-    ports:
-      - "8500:8500"
-    command: consul agent -dev -client=0.0.0.0
-    volumes:
-      - consul-data:/consul/data
-
-volumes:
-  consul-data:
-```
-
-### Local Development
-
-```bash
-# Run Consul in dev mode
-consul agent -dev
-
-# Or use Docker
-docker run -d --name consul -p 8500:8500 consul:latest
-```
-
-## Production Deployment
-
-### Kubernetes
-
-```yaml
-# Consul Helm Chart
-helm repo add hashicorp https://helm.releases.hashicorp.com
-helm install consul hashicorp/consul --set global.datacenter=dc1
-```
-
-### Standalone Cluster
-
-- Deploy Consul cluster (3-5 nodes)
-- Configure service discovery endpoints
-- Set up Consul Connect for service mesh (optional)
-
-## Consequences
-
-### Positive
-- **Dynamic Service Discovery**: Services can be added/removed without configuration changes
-- **Health Checking**: Automatic removal of unhealthy services
-- **Load Balancing**: Multiple service instances automatically discovered
-- **Configuration Management**: Consul KV store for service configuration
-- **Service Mesh Ready**: Can use Consul Connect for advanced features
-- **Development Friendly**: Easy local setup with Docker
-
-### Negative
-- **Additional Infrastructure**: Requires Consul cluster in production
-- **Network Dependency**: Services depend on Consul availability
-- **Configuration Complexity**: Need to configure Consul cluster
-- **Learning Curve**: Team needs to understand Consul concepts
-
-### Mitigations
-1. **High Availability**: Deploy Consul cluster (3+ nodes)
-2. **Caching**: Cache service instances to reduce Consul queries
-3. **Fallback**: Support Kubernetes service discovery as fallback
-4. **Documentation**: Comprehensive setup and usage documentation
-5. **Monitoring**: Monitor Consul health and service registration
-
-## Alternative: Kubernetes Service Discovery
-
-For Kubernetes deployments, we also support native Kubernetes service discovery:
-
-```go
-// internal/registry/kubernetes/k8s.go
-type KubernetesRegistry struct {
-    clientset kubernetes.Interface
-    namespace string
-}
-
-func (r *KubernetesRegistry) Discover(ctx context.Context, serviceName string) ([]*ServiceInstance, error) {
-    endpoints, err := r.clientset.CoreV1().Endpoints(r.namespace).Get(ctx, serviceName, metav1.GetOptions{})
-    // Convert K8s endpoints to ServiceInstance
-}
-```
-
-## Service Registry Factory
-
-```go
-// internal/registry/factory.go
-func NewServiceRegistry(cfg *config.Config) (registry.ServiceRegistry, error) {
-    switch cfg.Registry.Type {
-    case "consul":
-        return consul.NewRegistry(cfg.Registry.Consul)
-    case "kubernetes":
-        return kubernetes.NewRegistry(cfg.Registry.Kubernetes)
-    default:
-        return nil, fmt.Errorf("unknown registry type: %s", cfg.Registry.Type)
-    }
-}
-```

-# ADR-0034: Go Version Upgrade to 1.25.3
-
-## Status
-Accepted
-
-## Context
-ADR-0002 established Go 1.24.3 as the minimum required version. Since then:
-
-- Go 1.25.3 has been released with new features, performance improvements, and security fixes
-- The project requires access to newer language features and tooling improvements
-- Dependencies may benefit from Go 1.25.3 optimizations
-- The development team has Go 1.25.3 available and working
-
-## Decision
-Upgrade from **Go 1.24.3** to **Go 1.25.3** as the minimum required version for the platform.
-
-This decision supersedes [ADR-0002: Go Version](./0002-go-version.md).
-
-**Rationale:**
-- Access to latest Go features and performance improvements
-- Better security with latest patches
-- Improved tooling support and compiler optimizations
-- Ensures compatibility with latest ecosystem dependencies

-
-## Consequences
-
-### Positive
-- Access to latest Go features and performance improvements
-- Better security with latest patches
-- Modern tooling support with improved compiler optimizations
-- Better compatibility with latest dependency versions
-- Enhanced performance characteristics
-
-### Negative
-- Requires developers to upgrade to Go 1.25.3+
-- CI/CD must be updated to use Go 1.25.3
-- May require dependency updates for compatibility
-- Slightly higher barrier for developers still on older versions
-
-### Mitigations
-1. **Clear Documentation**: Update all documentation to specify Go 1.25.3 requirement
-2. **CI/CD Updates**: Ensure CI/CD pipelines use Go 1.25.3
-3. **Version Check**: Add version validation in build scripts if needed
-4. **Developer Communication**: Notify team of version requirement
-
-## Implementation Notes
-- Update `go.mod`: `go 1.25.3`
-- Update `.github/workflows/ci.yml` to use `actions/setup-go@v5` with version `1.25.3`
-- Update ADR-0002 to mark as Superseded
-- Update README.md and other documentation to reflect Go 1.25.3 requirement
-- Run `go mod tidy` to ensure dependency compatibility

-- **Feature Services**: Blog, Billing, Analytics, etc. - independent services
-- **Infrastructure Adapters**: Cache, Event Bus, Scheduler, etc. - shared infrastructure
-
-All services communicate via gRPC (primary) or HTTP (fallback) through service client interfaces, with service discovery via a service registry. Each service has its own database connection pool and schema. Services share infrastructure (PostgreSQL instance, Redis, Kafka) but are independently deployable and scalable.

For a lighter weight solution, use plain **constructor injection** with a small **registry**. |

Services discover each other via Consul service registry. |
+| **Modular Monolith → Micro‑service‑ready** | A single binary is cheap in Go; later you can extract modules into separate services without breaking APIs. | Each module lives in its own Go **module** (`go.mod`) under `./modules/*`. The core loads them via the **Go plugin** system *or* static registration (preferred for CI stability). |

 | **API‑First (OpenAPI + gin/gorilla)** | Guarantees language‑agnostic contracts. | Generate server stubs from an `openapi.yaml` stored in `api/`. |

-## 2.1 CORE SERVICES (Independent Microservices)
+All *public* interfaces live under `pkg/` so that plug‑ins can import them without pulling in implementation details. The concrete implementations stay in `internal/` (or separate go.mod modules) and are **registered with the container** during bootstrap.
-
-Core business services are implemented as separate, independently deployable services:
-
-| Service | Entry Point | Responsibilities | Service Client Interface |
-|--------|-------------|------------------|-------------------------|
-| **Auth Service** | `cmd/auth-service/` | JWT token generation/validation, authentication | `AuthServiceClient` in `pkg/services/auth.go` |
-| **Identity Service** | `cmd/identity-service/` | User CRUD, password management, email verification | `IdentityServiceClient` in `pkg/services/identity.go` |
-| **Authz Service** | `cmd/authz-service/` | Permission resolution, RBAC/ABAC authorization | `AuthzServiceClient` in `pkg/services/authz.go` |
-| **Audit Service** | `cmd/audit-service/` | Audit logging, immutable audit records | `AuditServiceClient` in `pkg/services/audit.go` |
-| **API Gateway** | `cmd/api-gateway/` | Request routing, authentication, rate limiting, CORS | N/A (entry point) |
-
-Each service:
-
-- Has its own `go.mod` (or shared workspace)
-- Manages its own database connection pool and schema
-- Exposes gRPC server (and optional HTTP)
-- Registers with Consul service registry
-- Uses service clients for inter-service communication
-
-All *public* interfaces live under `pkg/` so that services can import them without pulling in implementation details. The concrete implementations stay in `internal/` (for core kernel) or `services/{service}/internal/` (for service implementations) and are **registered with the container** during service bootstrap.
-
-**Note:** Business logic services (Auth, Identity, Authz, Audit) are NOT in the core kernel. They are separate services implemented in Epic 2.

-# Audit Service Implementation Summary
-
-## Overview
-
-The Audit Service has been successfully implemented as an independent microservice. It provides audit logging functionality with gRPC API, database persistence, and service registry integration.
-
-## Completed Components
-
-### 1. Service Implementation (`services/audit/internal/service/audit_service.go`)
-- **AuditService**: Core business logic for audit logging
-- **Record**: Records audit log entries to database
-- **Query**: Queries audit logs with filters (user_id, action, resource, time range, pagination)
-- Uses Ent ORM for database operations
-- Supports metadata as JSON
-
-### 2. gRPC Server Implementation (`cmd/audit-service/audit_service_fx.go`)
-- **auditServerImpl**: Implements `AuditService` gRPC interface
-- **Record RPC**: Records audit log entries
-- **Query RPC**: Queries audit logs with filters
-- Converts between proto types and service types
-- Error handling with proper gRPC status codes
-
-### 3. Service Entry Point (`cmd/audit-service/main.go`)
-- Independent service entry point
-- Dependency injection using uber-go/fx
-- Database connection with schema isolation (`audit` schema)
-- Automatic migrations on startup
-- Health check registry with database checker
-- gRPC server lifecycle management
-- Service registry registration (Consul)
-- Graceful shutdown handling
-
-### 4. Database Schema (`internal/ent/schema/audit_log.go`)
-- **AuditLog** entity with fields:
-  - `id`: Unique identifier
-  - `user_id`: ID of the user/actor
-  - `action`: Action performed (e.g., "user.create")
-  - `resource`: Resource type (e.g., "user", "role")
-  - `resource_id`: ID of the target resource
-  - `ip_address`: Client IP address
-  - `user_agent`: Client user agent
-  - `metadata`: Additional metadata as JSON
-  - `timestamp`: When the action occurred
-- Indexes on: user_id, resource_id, timestamp, action, resource
-
-### 5. Configuration (`config/default.yaml`)
-- Added service configuration:
-  ```yaml
-  services:
-    audit:
-      port: 8084
-      host: "localhost"
-  ```
-
-## Architecture
-
-The Audit Service follows the microservices architecture pattern:
-
-- **Independent Deployment**: Has its own entry point (`cmd/audit-service/main.go`)
-- **Schema Isolation**: Uses `audit` database schema
-- **Service Discovery**: Registers with Consul service registry
-- **gRPC API**: Exposes gRPC server on port 8084 (configurable)
-- **Health Checks**: Implements gRPC health check protocol
-- **Reflection**: Enabled for grpcurl testing

-## Testing the Audit Service
-
-### Prerequisites
-
-1. **PostgreSQL** running and accessible
-2. **Consul** running (optional, for service discovery)
-3. **Configuration** set up in `config/default.yaml`
-
-### Start the Service
-
-```bash
-# Using nix-shell (recommended)
-nix-shell
-go run ./cmd/audit-service/main.go
-
-# Or build and run
-go build -o bin/audit-service ./cmd/audit-service
-./bin/audit-service
-```
-
-### Verify Service Startup
-
-The service should:
-1. Connect to database
-2. Create `audit` schema if it doesn't exist
-3. Run migrations (create `audit_logs` table)
-4. Start gRPC server on port 8084
-5. Register with Consul (if available)
-
-Check logs for:
-- "Database migrations completed for audit service"
-- "Starting Audit Service gRPC server"
-- "Audit Service gRPC server started successfully"
-- "Registered Audit Service with service registry"
-
-### Test with grpcurl
-
-```bash
-# List available services
-grpcurl -plaintext localhost:8084 list
-
-# Check health
-grpcurl -plaintext localhost:8084 grpc.health.v1.Health/Check
-
-# Record an audit log entry
-grpcurl -plaintext -d '{

-
-# Query audit logs
-grpcurl -plaintext -d '{
-  "user_id": "user-123",
-  "limit": 10,
-  "offset": 0
-}' localhost:8084 audit.v1.AuditService/Query
-```
-
-### Verify Database
-
-```bash
-# Connect to database
-docker exec -it goplt-postgres psql -U goplt -d goplt
-
-# Switch to audit schema
-SET search_path TO audit;
-
-# Check table exists
-\dt
-
-# Query audit logs
-SELECT * FROM audit_logs ORDER BY timestamp DESC LIMIT 10;
-```
-
-## Next Steps
-
-The Audit Service is complete and ready for use. Other services (Auth, Identity, Authz) can use the Audit Service via the `AuditServiceClient` interface to record audit events.
-
-## Notes
-
-- The service uses inline implementation in `cmd/audit-service/audit_service_fx.go` to avoid importing internal packages from cmd
-- The internal service implementation in `services/audit/internal/service/` exists for reference and can be used by other internal packages
-- Service registry registration happens on startup; deregistration on shutdown (service ID stored for proper cleanup)
-- Health checks are available via gRPC health protocol

-**Note**: Database seeding scripts are not yet implemented. This can be added as a follow-up task to populate initial data (admin users, default roles, permissions).
-
-### Additional Implementation: gRPC Clients ✅
-**Status**: Complete
-
-**Implementation**:
-- **Auth Client**: `internal/client/grpc/auth_client.go`
-- **Identity Client**: `internal/client/grpc/identity_client.go`
-- **Authz Client**: `internal/client/grpc/authz_client.go`
-- **Audit Client**: `internal/client/grpc/audit_client.go`
-
-All clients:
-- Use service discovery via Consul
-- Implement full gRPC communication
-- Handle connection management
-- Convert between proto and service types
-
-## Architecture
-
-### Service Independence
-Each service:
-- Has its own entry point in `cmd/{service}/`
-- Manages its own database connection and schema
-- Registers with Consul service registry
-- Exposes gRPC server with health checks
-- Can be deployed independently
-
-### Database Schema Isolation
-- **Auth Service**: `auth` schema
-- **Identity Service**: `identity` schema
-- **Authz Service**: `authz` schema
-- **Audit Service**: `audit` schema
-
-### Service Communication
-- Services communicate via gRPC using service discovery
-- Service clients are available via `ServiceClientFactory`
-- Clients automatically discover and connect to service instances
-
-### Configuration
-All service configurations are in `config/default.yaml`:
-```yaml
-services:
-  auth:
-    port: 8081
-    host: "localhost"
-  identity:
-    port: 8082
-    host: "localhost"
-  authz:
-    port: 8083
-    host: "localhost"
-  audit:
-    port: 8084
-    host: "localhost"
-
-auth:
-  jwt_secret: "change-this-secret-in-production"
-```
-
-## Prerequisites
-
-1. **PostgreSQL** running and accessible
-2. **Consul** running (for service discovery, required for service registry)
-3. **Go 1.24+** (or use `nix-shell` for development environment)
-4. **NixOS** (optional, for `shell.nix` development environment)
-5. **Docker and Docker Compose** (for running PostgreSQL and Consul)
-
-## Building the Services
-
-### Using Nix Shell (Recommended)
-```bash
-# Enter nix shell (automatically loads via .envrc if using direnv)
-nix-shell
-
-# Build all services
-go build ./cmd/auth-service
-go build ./cmd/identity-service
-go build ./cmd/authz-service
-go build ./cmd/audit-service
-```
-
-### Without Nix
-```bash
-# Ensure you have:
-# - Go 1.24+
-# - protoc
-# - protoc-gen-go
-# - protoc-gen-go-grpc
-
-go build ./cmd/auth-service
-go build ./cmd/identity-service
-go build ./cmd/authz-service
-go build ./cmd/audit-service
-```
-
-## Running the Services
-
-### Option 1: Development Mode (Recommended for Development)
-
-Use `docker-compose.dev.yml` for infrastructure only, run services locally:
-
-```bash
-# Start only PostgreSQL and Consul
-docker-compose -f docker-compose.dev.yml up -d
-
-# Verify containers are running
-docker-compose -f docker-compose.dev.yml ps
-
-# Check logs
-docker-compose -f docker-compose.dev.yml logs postgres
-docker-compose -f docker-compose.dev.yml logs consul
-```
-
-Then start services locally:
-
-```bash
-# Terminal 1: Auth Service
-go run ./cmd/auth-service/*.go
-
-# Terminal 2: Identity Service
-go run ./cmd/identity-service/*.go
-
-# Terminal 3: Authz Service
-go run ./cmd/authz-service/*.go
-
-# Terminal 4: Audit Service
-go run ./cmd/audit-service/*.go
-```
-
-### Option 2: Full Docker Compose (All Services in Docker)
-
-Use `docker-compose.yml` to run everything in Docker:
-
-```bash
-# Build and start all services
-docker-compose up -d --build
-
-# View logs
-docker-compose logs -f
-
-# Stop all services
-docker-compose down
-```
-
-This will start:
-- PostgreSQL (port 5432)
-- Consul (port 8500)
-- Auth Service (port 8081)
-- Identity Service (port 8082)
-- Authz Service (port 8083)
-- Audit Service (port 8084)
-- API Gateway (port 8080)
-
-### Infrastructure Services
-
-Both docker-compose files include:
-- **PostgreSQL**: Available at `localhost:5432`
-  - Database: `goplt`
-  - User: `goplt`
-  - Password: `goplt_password`
-- **Consul**: Available at `localhost:8500`
-  - Running in dev mode
-  - Web UI: http://localhost:8500/ui (for viewing registered services)
-  - API: http://localhost:8500/v1
-
-### Alternative: Manual Setup
-```bash
-# Start PostgreSQL manually
-# Ensure database 'goplt' exists with user 'goplt' and password 'goplt_password'
-
-# Start Consul manually
-consul agent -dev
-```
-
-### 4. Verify Services
-
-Check service logs for:
-- Database connection success
-- Migration completion
-- gRPC server startup
-- Service registry registration
-
-## Testing the Services
-
-### Using grpcurl
-
-#### 1. Identity Service - Create User
-```bash
-grpcurl -plaintext -d '{
-  "email": "user@example.com",
-  "password": "securepassword123",
-  "username": "testuser",
-  "first_name": "Test",
-  "last_name": "User"
-}' localhost:8082 identity.v1.IdentityService/CreateUser
-```
-
-#### 2. Identity Service - Get User
-```bash
-grpcurl -plaintext -d '{
-  "id": "USER_ID_FROM_CREATE"
-}' localhost:8082 identity.v1.IdentityService/GetUser
-```
-
-#### 3. Auth Service - Login
-```bash
-grpcurl -plaintext -d '{
-  "email": "user@example.com",
-  "password": "securepassword123"
-}' localhost:8081 auth.v1.AuthService/Login
-```
-
-#### 4. Auth Service - Validate Token

-}' localhost:8081 auth.v1.AuthService/ValidateToken
-```
-
-#### 5. Authz Service - Get User Roles
-```bash
-grpcurl -plaintext -d '{
-  "user_id": "USER_ID"
-}' localhost:8083 authz.v1.AuthzService/GetUserRoles
-```
-
-#### 6. Audit Service - Record Audit Log
-```bash
-grpcurl -plaintext -d '{
-  "entry": {
-    "user_id": "user-123",
-    "action": "user.login",
-    "resource": "user",
-    "resource_id": "user-123",
-    "ip_address": "192.168.1.1",
-    "user_agent": "Mozilla/5.0",
-    "metadata": {
-      "method": "POST",
-      "endpoint": "/api/v1/auth/login"
-    },
-    "timestamp": 1699123456
-  }
-}' localhost:8084 audit.v1.AuditService/Record
-```
-
-#### 7. Audit Service - Query Audit Logs
-```bash
-grpcurl -plaintext -d '{
-  "user_id": "user-123",
-  "limit": 10,
-  "offset": 0
-}' localhost:8084 audit.v1.AuditService/Query
-```
-
-### Health Checks
-
-All services expose gRPC health checks:
-```bash
-grpcurl -plaintext localhost:8081 grpc.health.v1.Health/Check
-grpcurl -plaintext localhost:8082 grpc.health.v1.Health/Check
-grpcurl -plaintext localhost:8083 grpc.health.v1.Health/Check
-grpcurl -plaintext localhost:8084 grpc.health.v1.Health/Check
-```
-
-## Verification
-
-### Verify Consul
-```bash
-# Check Consul is running
-curl http://localhost:8500/v1/status/leader
-
-# List registered services
-curl http://localhost:8500/v1/agent/services
-
-# Or use Consul UI
-# Open http://localhost:8500/ui in your browser
-```
-
-### Database Verification
-
-#### Check Schemas
-```bash
-docker exec -it goplt-postgres psql -U goplt -d goplt -c "\dn"
-```
-
-### Check Tables
-```bash
-# Auth schema
-docker exec -it goplt-postgres psql -U goplt -d goplt -c "SET search_path TO auth; \dt"
-
-# Identity schema
-docker exec -it goplt-postgres psql -U goplt -d goplt -c "SET search_path TO identity; \dt"
-
-# Authz schema
-docker exec -it goplt-postgres psql -U goplt -d goplt -c "SET search_path TO authz; \dt"
-
-# Audit schema
-docker exec -it goplt-postgres psql -U goplt -d goplt -c "SET search_path TO audit; \dt"
-```
-
-## Known Issues and TODOs
-
-### 1. RefreshToken Entity
-- **Issue**: RefreshToken entity schema is defined but Ent code needs to be regenerated
-- **Impact**: Auth Service refresh token operations return placeholder errors
-- **Fix**: Run `go generate ./ent/...` or `go run -mod=readonly entgo.io/ent/cmd/ent generate ./ent/schema`
-- **Location**: `internal/ent/schema/refresh_token.go`
-
-### 2. Database Seeding
-- **Status**: Not implemented
-- **Impact**: No initial data (admin users, default roles, permissions)
-- **Future Work**: Create seed scripts for each service
-
-### 3. Tests
-- **Status**: Not implemented
-- **Impact**: No automated test coverage
-- **Future Work**: Add unit tests, integration tests, and E2E tests
-
-### 4. Auth Service - Password Verification
-- **Issue**: Auth Service login doesn't verify password with Identity Service
-- **Impact**: Login may not work correctly
-- **Fix**: Identity Service needs to expose VerifyPassword RPC or Auth Service should call it directly
-
-### 5. Auth Service - Role Retrieval
-- **Issue**: Auth Service doesn't retrieve user roles from Authz Service
-- **Impact**: JWT tokens don't include user roles
-- **Fix**: Integrate with Authz Service to get user roles during login

 ## Goal
-Design module interface for feature services with service registration and dependency resolution. Modules are services that register with Consul and communicate via service clients.
+Design and implement the complete module system interface with registration, dependency resolution, and lifecycle management.
 
 ## Description
-This story creates the foundation for feature services (modules) by defining the module interface, manifest structure, and service registration. Feature services are independent services with their own entry points, gRPC servers, and database schemas. They register with Consul and use service clients for inter-service communication.
+This story creates the foundation of the module system by defining the module interface, manifest structure, and registry. The system must support module registration, dependency validation, and lifecycle hooks.

-  - Name, Version, Dependencies (service names)
+  - Name, Version, Dependencies
   - Permissions list
-  - gRPC service definitions

-- Common bootstrap pattern for feature services
+- Scan `./plugins/*.so` files
-- FX lifecycle integration
+- Load via `plugin.Open()`
-- Service registration helpers
+- Extract and validate module symbols
-- Health check setup

-### 4. Service Template/Scaffolding
+### 4. Module Initializer (`internal/module/initializer.go`)
-- Service template generator
+- Collect all registered modules
-- Standard service structure
+- Resolve dependency order (topological sort)
-- Example service entry point
+- Initialize each module's `Init()` fx.Option
+- Merge all options into main fx container
+- Run migrations in dependency order
+- Handle errors gracefully
 
-**Note:** Each feature service has its own `cmd/{service}/main.go` that uses these helpers to initialize itself.
