+# Epic 0: Implementation Summary
+
+## Overview
+
+Epic 0 establishes the foundation of the Go Platform project with core infrastructure components that enable all future development. This epic includes project initialization, configuration management, structured logging, CI/CD pipeline, and dependency injection setup.
+
+## Completed Stories
+
+### ✅ 0.1 Project Initialization
+- Go module initialized with proper module path
+- Complete directory structure following Clean Architecture
+- `.gitignore` configured for Go projects
+- Comprehensive README with project overview
+
+### ✅ 0.2 Configuration Management System
+- `ConfigProvider` interface in `pkg/config/`
+- Viper-based implementation in `internal/config/`
+- YAML configuration files in `config/` directory
+- Environment variable support with automatic mapping
+- Type-safe configuration access methods
+
+### ✅ 0.3 Structured Logging System
+- `Logger` interface in `pkg/logger/`
+- Zap-based implementation in `internal/logger/`
+- JSON and console output formats
+- Configurable log levels
+- Request ID and context-aware logging support
+
+### ✅ 0.4 CI/CD Pipeline
+- GitHub Actions workflow for automated testing and linting
+- Comprehensive Makefile with common development tasks
+- Automated build and test execution
+
+### ✅ 0.5 Dependency Injection and Bootstrap
+- DI container using Uber FX in `internal/di/`
+- Provider functions for core services
+- Application entry point in `cmd/platform/main.go`
+- Lifecycle management with graceful shutdown
+
+## Verification Instructions
+
+### Prerequisites
+- Go 1.24 or later installed
+- Make installed (optional, for using Makefile commands)
+
+### 1. Verify Project Structure
+
+```bash
+# Check Go module
+go mod verify
+
+# Check directory structure
+ls -la
+# Should see: cmd/, internal/, pkg/, config/, docs/, etc.
+```
+
+### 2. Verify Configuration System
+
+```bash
+# Build the application
+go build ./cmd/platform
+
+# Check if config files exist
+ls -la config/
+# Should see: default.yaml, development.yaml, production.yaml
+
+# Test config loading (will fail without database, but config should load)
+# This will be tested in Epic 1 when database is available
+```
+
+### 3. Verify Logging System
+
+```bash
+# Run tests for logging
+go test ./internal/logger/...
+
+# Expected output: Tests should pass
+```
+
+### 4. Verify CI/CD Pipeline
+
+```bash
+# Run linting (if golangci-lint is installed)
+make lint
+
+# Run tests
+make test
+
+# Build the application
+make build
+# Binary should be created in bin/platform
+
+# Run all checks
+make check
+```
+
+### 5. Verify Dependency Injection
+
+```bash
+# Build the application
+go build ./cmd/platform
+
+# Check if DI container compiles
+go build ./internal/di/...
+
+# Run the application (will fail without database in Epic 1)
+# go run ./cmd/platform/main.go
+```
+
+### 6. Verify Application Bootstrap
+
+```bash
+# Build the application
+make build
+
+# Check if binary exists
+ls -la bin/platform
+
+# The application should be ready to run (database connection will be tested in Epic 1)
+```
+
+## Testing Configuration
+
+The configuration system can be tested by:
+
+1. **Modifying config files**: Edit `config/default.yaml` and verify changes are loaded
+2. **Environment variables**: Set `ENVIRONMENT=production` and verify production config is loaded
+3. **Type safety**: Configuration access methods (`GetString`, `GetInt`, etc.) provide compile-time safety
+
+## Testing Logging
+
+The logging system can be tested by:
+
+1. **Unit tests**: Run `go test ./internal/logger/...`
+2. **Integration**: Logging will be tested in Epic 1 when HTTP server is available
+3. **Format switching**: Change `logging.format` in config to switch between JSON and console output
+
+## Common Issues and Solutions
+
+### Issue: `go mod verify` fails
+**Solution**: Run `go mod tidy` to update dependencies
+
+### Issue: Build fails
+**Solution**: Ensure Go 1.24+ is installed and all dependencies are downloaded (`go mod download`)
+
+### Issue: Config not loading
+**Solution**: Ensure `config/default.yaml` exists and is in the correct location relative to the binary
+
+## Next Steps
+
+After verifying Epic 0, proceed to [Epic 1](../epic1/SUMMARY.md) to set up the database and HTTP server, which will enable full end-to-end testing of the configuration and logging systems.

+The project includes a `docker-compose.yml` file for easy database setup:
+
+```bash
+# Start PostgreSQL container
+docker-compose up -d postgres
+
+# Verify container is running
+docker-compose ps
+
+# Check database logs
+docker-compose logs postgres
+```
+
+The database will be available at:
+- **Host**: `localhost`
+- **Port**: `5432`
+- **Database**: `goplt`
+- **User**: `goplt`
+- **Password**: `goplt_password`
+
+### 2. Configure Database Connection
+
+Update `config/default.yaml` or set environment variable:
+
+```bash
+# Option 1: Edit config/default.yaml
+# Set database.dsn to:
+database:
+  dsn: "postgres://goplt:goplt_password@localhost:5432/goplt?sslmode=disable"
+
+# Option 2: Set environment variable
+export DATABASE_DSN="postgres://goplt:goplt_password@localhost:5432/goplt?sslmode=disable"
+```
+
+### 3. Build and Run the Application
+
+```bash
+# Build the application
+make build
+
+# Or build directly
+go build -o bin/platform ./cmd/platform
+
+# Run the application
+./bin/platform
+
+# Or run directly
+go run ./cmd/platform/main.go
+```
+
+The application will:
+1. Load configuration
+2. Initialize logger
+3. Connect to database
+4. Run migrations (create tables)
+5. Start HTTP server on port 8080
+
+## Verification Instructions
+
+### 1. Verify Database Connection and Migrations
+
+#### Option A: Using Application Logs
+
+When you start the application, you should see:
+- Database connection successful
+- Migrations executed (tables created)
+
+#### Option B: Using PostgreSQL Client
+
+```bash
+# Connect to database
+docker exec -it goplt-postgres psql -U goplt -d goplt
+
+# List tables (should see User, Role, Permission, AuditLog, etc.)
+\dt
+
+# Check a specific table structure
+\d users
+\d roles
+\d permissions
+\d audit_logs
+
+# Exit psql
+\q
+```
+
+#### Option C: Using SQL Query
+
+```bash
+# Execute SQL query
+docker exec -it goplt-postgres psql -U goplt -d goplt -c "SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';"
+
+# Expected output should include:
+# - users
+# - roles
+# - permissions
+# - audit_logs
+# - user_roles
+# - role_permissions
+```
+
+### 2. Verify Health Endpoints
+
+```bash
+# Test liveness probe (should return 200)
+curl http://localhost:8080/healthz
+
+# Expected response:
+# {"status":"healthy"}
+
+# Test readiness probe (should return 200 if database is connected)
+curl http://localhost:8080/ready
+
+# Expected response:
+# {"status":"healthy","components":[{"name":"database","status":"healthy"}]}
+
+# If database is not connected, you'll see:
+# {"status":"unhealthy","components":[{"name":"database","status":"unhealthy","error":"..."}]}
+```
+
+### 3. Verify Metrics Endpoint
+
+```bash
+# Get Prometheus metrics
+curl http://localhost:8080/metrics
+
+# Expected output should include:
+# - http_request_duration_seconds
+# - http_requests_total
+# - http_errors_total
+# - go_* (Go runtime metrics)
+# - process_* (Process metrics)
+```
+
+### 4. Verify HTTP Server Functionality
+
+```bash
+# Make a request to trigger logging and metrics
+curl -v http://localhost:8080/healthz
+
+# Check application logs for:
+# - Request ID in logs
+# - Structured JSON logs
+# - Request method, path, status, duration
+```
+
+### 5. Verify Error Handling
+
+To test panic recovery and error bus:
+
+```bash
+# The error bus will capture any panics automatically
+# Check logs for error bus messages when errors occur
+```
+
+### 6. Verify OpenTelemetry Tracing
+
+#### Development Mode (stdout)
+
+When `tracing.enabled: true` and `environment: development`, traces are exported to stdout:
+
+```bash
+# Start the application and make requests
+curl http://localhost:8080/healthz
+
+# Check application stdout for trace output
+# Should see JSON trace spans with:
+# - Trace ID
+# - Span ID
+# - Operation name
+# - Attributes (method, path, status, etc.)
+```
+
+#### Verify Trace ID in Logs
+
+```bash
+# Make a request
+curl http://localhost:8080/healthz
+
+# Check application logs for trace_id and span_id fields
+# Example log entry:
+# {"level":"info","msg":"HTTP request","method":"GET","path":"/healthz","status":200,"trace_id":"...","span_id":"..."}
+```
+
+### 7. Verify Database Operations
+
+#### Test Database Write
+
+You can test database operations by creating a simple test script or using the database client directly. For now, verify that migrations worked (see Verification 1).
+
+#### Test Database Health Check
+
+```bash
+# The /ready endpoint includes database health check
+curl http://localhost:8080/ready
+
+# If healthy, you'll see database component status: "healthy"
+```
+
+## Testing Database Specifically
+
+### Direct Database Testing
+
+1. **Connect to Database**:
+```bash
+docker exec -it goplt-postgres psql -U goplt -d goplt
+```
+
+2. **Verify Tables Exist**:
+```sql
+SELECT table_name 
+FROM information_schema.tables 
+WHERE table_schema = 'public' 
+ORDER BY table_name;
+```
+
+3. **Check Table Structures**:
+```sql
+-- Check users table
+\d users
+
+-- Check relationships
+\d user_roles
+\d role_permissions
+```
+
+4. **Test Insert Operation** (manual test):
+```sql
+-- Note: Ent generates UUIDs, so we'd need to use the Ent client
+-- This is just to verify the schema is correct
+-- Actual inserts should be done through the application/Ent client
+```
+
+### Using Application to Test Database
+
+The database is automatically tested through:
+1. **Migrations**: Run on startup - if they succeed, schema is correct
+2. **Health Check**: `/ready` endpoint tests database connectivity
+3. **Connection Pool**: Database client manages connections automatically
+
+## Docker Compose Commands
+
+```bash
+# Start database
+docker-compose up -d postgres
+
+# Stop database
+docker-compose stop postgres
+
+# Stop and remove containers
+docker-compose down
+
+# Stop and remove containers + volumes (WARNING: deletes data)
+docker-compose down -v
+
+# View database logs
+docker-compose logs -f postgres
+
+# Access database shell
+docker exec -it goplt-postgres psql -U goplt -d goplt
+
+# Check database health
+docker-compose ps
+```
+
+## Common Issues and Solutions
+
+### Issue: Database connection fails
+
+**Symptoms**: Application fails to start, error about database connection
+
+**Solutions**:
+1. Ensure PostgreSQL container is running: `docker-compose ps`
+2. Check database DSN in config: `postgres://goplt:goplt_password@localhost:5432/goplt?sslmode=disable`
+3. Verify port 5432 is not in use: `lsof -i :5432`
+4. Check database logs: `docker-compose logs postgres`
+
+### Issue: Migrations fail
+
+**Symptoms**: Error during startup about migrations
+
+**Solutions**:
+1. Ensure database is accessible
+2. Check database user has proper permissions
+3. Verify Ent schema is correct: `go generate ./internal/ent`
+4. Check for existing tables that might conflict
+
+### Issue: Health check fails
+
+**Symptoms**: `/ready` endpoint returns unhealthy
+
+**Solutions**:
+1. Verify database connection
+2. Check database health: `docker-compose ps`
+3. Review application logs for specific error
+
+### Issue: Metrics not appearing
+
+**Symptoms**: `/metrics` endpoint is empty or missing metrics
+
+**Solutions**:
+1. Make some HTTP requests first (metrics are collected per request)
+2. Verify Prometheus registry is initialized
+3. Check middleware is registered correctly
+
+### Issue: Traces not appearing
+
+**Symptoms**: No trace output in logs
+
+**Solutions**:
+1. Verify `tracing.enabled: true` in config
+2. Check environment is set correctly (development = stdout, production = OTLP)
+3. Make HTTP requests to generate traces
+
+## Expected Application Output
+
+When running successfully, you should see logs like:
+
+```json
+{"level":"info","msg":"Application starting","component":"bootstrap"}
+{"level":"info","msg":"Database migrations completed"}
+{"level":"info","msg":"HTTP server listening","addr":"0.0.0.0:8080"}
+```
+
+When making requests:
+```json
+{"level":"info","msg":"HTTP request","method":"GET","path":"/healthz","status":200,"duration_ms":5,"request_id":"...","trace_id":"...","span_id":"..."}
+```
+
+## Next Steps
+
+After verifying Epic 1:
+1. All core infrastructure is in place
+2. Database is ready for Epic 2 (Authentication & Authorization)
+3. HTTP server is ready for API endpoints
+4. Observability is ready for production monitoring
+
+Proceed to [Epic 2](../epic2/README.md) to implement authentication and authorization features.
