-# BDD Testing with Godog
+# BDD Testing Framework
 
-This package implements Behavior-Driven Development (BDD) testing using the Godog framework.
+This directory contains the Behavior-Driven Development (BDD) testing framework for the dance-lessons-coach project, implementing the architecture described in ADR 0024.
 
-## Important Requirements for Step Definitions
+## 🗺️ Architecture Overview
 
-### Step Pattern Matching
+The BDD framework follows a modular, isolated test suite architecture with these key components:
 
-Godog has **very specific requirements** for step pattern matching. To avoid "undefined" warnings:
+### 📁 Directory Structure
 
-1. **Use the exact regex pattern** that Godog suggests in its error messages
-2. **Use the exact parameter names** that Godog suggests (`arg1, arg2`, etc.)
-3. **Match the feature file syntax exactly** including quotes and JSON formatting
-
-### Example
-
-**Feature file step:**
-```gherkin
-Then the response should be "{\"message\":\"Hello world!\"}"
+```

 ```
 
-**Correct step definition:**
+## 🎯 Core Components
+
+### 1. Test Server
+
+**Location:** `pkg/bdd/testserver/`
+
+The test server provides a real HTTP server instance for black-box testing:
+
+- **Hybrid Testing**: Runs in-process (not external process)
+- **Configuration**: Loads feature-specific configs from `features/*/*-test-config.yaml`
+- **Database**: Manages PostgreSQL connections with proper isolation
+- **Port Management**: Uses feature-specific ports (9192-9196)
+
+**Key Functions:**
+- `NewServer()` - Creates test server instance
+- `Start()` - Starts server with feature-specific configuration
+- `initDBConnection()` - Initializes database connection
+- `createTestConfig()` - Loads feature-specific configuration
+
+### 2. Step Definitions
+
+**Location:** `pkg/bdd/steps/`
+
+Step definitions implement the Gherkin scenarios using Godog:
+
+- **Domain-Specific**: Organized by feature area (auth, config, greet, etc.)
+- **Reusable**: Common patterns in `common_steps.go`
+- **Exact Matching**: Uses Godog's exact regex patterns
+
+**Example:**
 ```go
-ctx.Step(`^the response should be "{\"([^"]*)\":\"([^"]*)\"}"$`, func(arg1, arg2 string) error {
-    // Implementation here
-    return nil
-})
+// greet_steps.go
+func (gs *GreetSteps) iRequestAGreetingFor(name string) error {
+    return gs.client.Request("GET", fmt.Sprintf("/api/v1/greet/%s", name), nil)
+}
 ```
 
-**Incorrect patterns that cause "undefined" warnings:**
+### 3. Synchronization Helpers
+
+**Location:** `pkg/bdd/helpers/`
+
+Helpers provide robust waiting mechanisms for async operations:
+
+- **Timeout Support**: All functions include timeout parameters
+- **Polling**: Uses context-based polling with configurable intervals
+- **Common Patterns**: Covers server readiness, config reload, API availability
+
+**Available Helpers:**
+- `waitForServerReady()` - Waits for server to be ready
+- `waitForConfigReload()` - Detects configuration changes
+- `waitForCondition()` - Generic condition waiting
+- `waitForV2APIEnabled()` - Checks v2 API availability
+
+### 4. Parallel Testing
+
+**Location:** `pkg/bdd/parallel/`
+
+Parallel execution infrastructure for CI/CD optimization:
+
+- **Port Management**: `PortManager` allocates unique ports
+- **Resource Monitoring**: Tracks memory, goroutines, CPU usage
+- **Controlled Parallelism**: `ParallelTestRunner` limits concurrency
+
+**Key Features:**
+- Thread-safe port allocation
+- Resource limit enforcement
+- Timeout detection
+- Comprehensive monitoring
+
+### 5. Feature Contexts
+
+**Location:** `pkg/bdd/context/`
+
+Feature-specific test contexts for better organization:
+
+- **AuthContext**: User management and authentication
+- **ConfigContext**: Configuration file handling
+- **Extensible**: Easy to add new feature contexts
+
+## 🚀 Test Execution
+
+### Running All Tests
+
+```bash
+# Default: Run all features sequentially
+go test ./features/...
+
+# With environment variables
+DLC_DATABASE_HOST=localhost DLC_DATABASE_PORT=5432 \
+DLC_DATABASE_USER=postgres DLC_DATABASE_PASSWORD=postgres \
+DLC_DATABASE_NAME=dance_lessons_coach_bdd_test \
+DLC_DATABASE_SSL_MODE=disable \
+go test ./features/...
+```
+
+### Feature-Specific Testing
+
+```bash
+# Test specific feature
+./scripts/test-feature.sh greet
+
+# Test with specific tags
+./scripts/test-by-tag.sh @smoke greet
+```
+
+### Parallel Testing
+
+```bash
+# Run all features in parallel
+./scripts/test-all-features-parallel.sh
+
+# Run specific features in parallel
+# (Requires PostgreSQL container running)
+```
+
+### Tag-Based Testing
+
+```bash
+# List available tags
+./scripts/run-bdd-tests.sh list-tags
+
+# Run smoke tests
+./scripts/run-bdd-tests.sh run @smoke
+
+# Run critical tests for auth
+./scripts/run-bdd-tests.sh run @critical @auth
+```
+
+## 📋 Test Organization
+
+### Feature Structure
+
+Each feature follows this structure:
+
+```
+features/{feature}/
+├── {feature}.feature       # Gherkin scenarios
+├── {feature}-test-config.yaml # Feature-specific config
+└── {feature}_test.go       # Go test runner
+```
+
+### Configuration Files
+
+Feature-specific YAML files define test environment:
+
+```yaml
+# features/greet/greet-test-config.yaml
+server:
+  host: "127.0.0.1"
+  port: 9194
+
+database:
+  host: "localhost"
+  port: 5432
+  name: "dance_lessons_coach_greet_test"
+
+api:
+  v2_enabled: true
+```
+
+### Tagging System
+
+Comprehensive tagging for selective test execution:
+
+- **Feature Tags**: `@auth`, `@config`, `@greet`, `@health`, `@jwt`
+- **Priority Tags**: `@smoke`, `@critical`, `@basic`, `@advanced`
+- **Component Tags**: `@api`, `@v2`, `@database`, `@security`
+
+See `features/BDD_TAGS.md` for complete documentation.
+
+## 🔧 Database Management
+
+### Database Creation
+
+The framework handles database creation automatically:
+
+1. **PostgreSQL Container**: Uses Docker (`dance-lessons-coach-postgres`)
+2. **Feature Databases**: Creates `dance_lessons_coach_{feature}_test` per feature
+3. **Cleanup**: Automatically drops databases after tests
+
+**Database Creation Flow:**
+1. Check if database exists
+2. Create if missing (`createdb` command)
+3. Run tests with isolated database
+4. Cleanup (`dropdb` command)
+
+### Configuration
+
+Database settings come from:
+- Environment variables (`DLC_DATABASE_*`)
+- Feature-specific config files
+- Default values for development
+
+## 🧪 Best Practices
+
+### Step Definition Patterns
+
 ```go
-// Wrong: Different regex pattern
-ctx.Step(`^the response should be "{\"message\":\"([^"]*)\"}"$`, func(message string) error {
-    // ...
-})
+// ✅ DO: Use Godog's exact regex patterns
+ctx.Step(`^I request a greeting for "([^"]*)"$`, sc.iRequestAGreetingFor)
 
-// Wrong: Different parameter names
-ctx.Step(`^the response should be "{\"([^"]*)\":\"([^"]*)\"}"$`, func(key, value string) error {
-    // ...
-})
+// ❌ DON'T: Use different patterns
+ctx.Step(`^I request greeting "(.*)"$`, sc.iRequestAGreetingFor)
 ```
 
-## Current Implementation
+### Test Isolation
 
-### Step Definition Strategy
+- Each feature has unique port and database
+- No shared state between features
+- Cleanup after each test run
+- Feature-specific configuration
 
-1. **First eliminate "undefined" warnings** by using Godog's exact suggested patterns
-2. **Return `godog.ErrPending`** initially to confirm pattern matching works
-3. **Then implement actual validation** logic
+### Synchronization
 
-### Files
+```go
+// ✅ DO: Use helpers for async operations
+helpers.waitForServerReady(client, 30*time.Second)
 
-- `suite.go`: Test suite initialization and server management
-- `testserver/`: Test server and client implementation
-- `steps/`: Step definitions for each feature
+// ❌ DON'T: Use fixed sleep times
+time.Sleep(5 * time.Second)
+```
 
-## Debugging "Undefined" Steps
+### Context Management
 
-If you see "undefined" warnings:
+```go
+// ✅ DO: Use feature-specific contexts
+switch featureName {
+case "auth":
+    authCtx = context.NewAuthContext(client)
+    context.InitializeAuthContext(ctx, client)
+}
+```
 
-1. Run the tests to see Godog's suggested pattern:
-   ```bash
-   go test ./features/... -v
-   ```
+## 📈 Performance Optimization
 
-2. Copy the **exact regex pattern** from the error message
-3. Copy the **exact parameter names** (`arg1, arg2`, etc.)
-4. Update your step definition to match exactly
+### Parallel Execution
 
-## Common Mistakes
+- Use `scripts/test-all-features-parallel.sh` for CI/CD
+- Limit parallelism based on system resources
+- Monitor resource usage with `ResourceMonitor`
 
-The "undefined" warnings are **not a Godog bug** - they occur when step definitions don't match Godog's expected patterns exactly:
+### Selective Testing
 
-- Using different regex patterns than what Godog suggests
-- Using descriptive parameter names instead of `arg1, arg2`
-- Not escaping quotes properly in JSON patterns
-- Trying to be "clever" with regex optimization
+- Run only relevant tests with tag filtering
+- Use `@smoke` for quick validation
+- Use `@critical` for essential path testing
 
-**Solution**: Always use the exact pattern and parameter names that Godog suggests in its error messages.
+### Resource Management
 
-## Best Practices
+- Set appropriate timeouts
+- Limit maximum goroutines
+- Monitor memory usage
+- Cleanup resources promptly
 
-1. **Follow Godog's suggestions exactly** - Copy-paste the pattern and parameter names
-2. **Test pattern matching first** - Use `godog.ErrPending` to verify patterns work
-3. **Then implement logic** - Replace `godog.ErrPending` with actual validation
-4. **Don't over-optimize regex** - Use the patterns Godog provides, even if they seem verbose
-5. **One pattern per step type** - Use generic patterns to cover similar steps
+## 🔧 Troubleshooting
 
-## Why This Matters
+### Common Issues
 
-Godog's step matching is **very specific by design**:
-- It needs to reliably match feature file steps to code
-- It provides exact patterns to ensure consistency
-- Following its suggestions guarantees your steps will be recognized
+| Issue | Cause | Solution |
+|-------|-------|----------|
+| Undefined steps | Step pattern mismatch | Use Godog's exact suggested patterns |
+| Port conflicts | Multiple servers | Check port allocation in config files |
+| Database connection | PostgreSQL not running | Start with `docker compose up -d postgres` |
+| Test isolation | Shared state | Verify unique ports/databases per feature |
 
-**Remember**: The "undefined" warnings are Godog telling you exactly how to fix your step definitions!
+### Debugging
+
+```bash
+# Verbose output
+go test ./features/... -v
+
+# Check specific feature
+cd features/greet && go test -v .
+
+# List available tags
+./scripts/run-bdd-tests.sh list-tags
+```

 - Use descriptive, action-oriented names
 - Follow the pattern: `i[Action][Object]` or `the[Object][State]`
 - Example: `iRequestAGreetingFor`, `theAuthenticationShouldBeSuccessful`
+- Use present tense for actions: "I authenticate", "the server reloads"
+
+## State Isolation Pattern
+
+**Problem:** Step definition structs (AuthSteps, GreetSteps, etc.) maintain state in their fields (e.g., `lastToken`, `lastUserID`). This state persists across all scenarios in a test process, causing pollution even with database schema isolation.
+
+**Solution:** Use the `ScenarioState` manager for per-scenario state isolation.
+
+### How It Works
+
+The `scenario_state.go` provides a thread-safe mechanism to store and retrieve state that is isolated per scenario:
+
+```go
+// Get scenario-specific state
+state := steps.GetScenarioState(scenarioName)
+
+// Store scenario-specific data
+state.LastToken = token
+state.LastUserID = userID
+
+// Retrieve scenario-specific data
+token := state.LastToken
+```
+
+### Usage in Step Definitions
+
+Instead of storing state in struct fields:
+
+```go
+// ❌ NOT RECOMMENDED - state shared across all scenarios
+type AuthSteps struct {
+    client     *testserver.Client
+    lastToken  string  // Shared across all scenarios!
+    lastUserID uint    // Shared across all scenarios!
+}
+
+func (s *AuthSteps) iShouldReceiveAValidJWTToken() error {
+    s.lastToken = extractedToken  // Pollutes other scenarios
+    return nil
+}
+```
+
+Use per-scenario state:
+
+```go
+// ✅ RECOMMENDED - state isolated per scenario
+type AuthSteps struct {
+    client     *testserver.Client
+    scenarioName string  // Track current scenario for state isolation
+}
+
+func (s *AuthSteps) iShouldReceiveAValidJWTToken() error {
+    state := steps.GetScenarioState(s.scenarioName)
+    state.LastToken = extractedToken  // Isolated to this scenario
+    return nil
+}
+```
+
+### Integration with Suite Hooks
+
+Clear state in AfterScenario to prevent memory growth:
+
+```go
+sc.AfterScenario(func(s *godog.Scenario, err error) {
+    scenarioKey := s.Name
+    if s.Uri != "" {
+        scenarioKey = fmt.Sprintf("%s:%s", s.Uri, s.Name)
+    }
+    steps.ClearScenarioState(scenarioKey)
+})
+```
+
+### ScenarioState Structure
+
+The `ScenarioState` struct contains common fields needed across step definitions:
+
+```go
+type ScenarioState struct {
+    LastToken  string
+    FirstToken string
+    LastUserID uint
+    // Add more fields as needed for other step types
+}
+```
+
+If you need additional scenario-scoped fields, add them to the `ScenarioState` struct.
 
 ## Testing the Steps
 
 Run BDD tests with:
 ```bash
+# Run all features
 go test ./features/... -v
+
+# Run specific feature
+go test ./features/auth -v
+
+# Run with state tracing enabled
+BDD_TRACE_STATE=1 go test ./features/auth -v
+
+# Validate full test suite
+./scripts/validate-test-suite.sh 1
+```
+
+## State Cleanup Strategy
+
+| Cleanup Level | When | What | Implementation |
+|---------------|------|------|----------------|
+| Per-Scenario | After each scenario | Step struct fields | `ClearScenarioState()` |
+| Per-Scenario | After each scenario | Database state | `CleanupDatabase()` (if no schema isolation) |
+| Per-Scenario | After each scenario | Schema | `DROP SCHEMA` (if schema isolation enabled) |
+| Per-Process | After each feature test | Server-level state | `ResetJWTSecrets()` |
+| Per-Suite | After all scenarios | All state | Server restart |
+
+## Best Practices
+
+### 1. Use Per-Scenario State for Shared Data
+
+Any data that:
+- Is modified during scenario execution
+- Affects subsequent steps in the same scenario
+- Should NOT affect other scenarios
+
+**Use:** `GetScenarioState(scenarioName).Field`
+
+### 2. Keep Step Definitions Stateless Where Possible
+
+If a step doesn't need to store intermediate state, don't store it:
+```go
+// ✅ Good - stateless
+func (s *GreetSteps) iRequestAGreetingFor(name string) error {
+    return s.client.Request("GET", fmt.Sprintf("/api/v1/greet/%s", name), nil)
+}
+
+// ❌ Avoid - unnecessary state
+func (s *GreetSteps) iRequestAGreetingFor(name string) error {
+    s.lastGreetedName = name  // Unnecessary unless used later
+    return s.client.Request("GET", fmt.Sprintf("/api/v1/greet/%s", name), nil)
+}
+```
+
+### 3. Prefix Config Files Per-Scenario
+
+If your scenario modifies config files, use scenario-specific paths:
+```go
+configPath := fmt.Sprintf("features/%s/%s-scenario-%s.yaml", 
+    feature, feature, scenarioKey)
+```
+
+### 4. Document Dependencies
+
+If a step depends on state set by another step, document it:
+
+```go
+// Step: The user should have a valid JWT token
+// Requires: iAuthenticateWithUsernameAndPassword to have been called first
+func (s *AuthSteps) theUserShouldHaveAValidJWTToken() error {
+    state := steps.GetScenarioState(s.scenarioName)
+    if state.LastToken == "" {
+        return fmt.Errorf("no token found - did you authenticate first?")
+    }
+    // Verify token is valid...
+}
 ```

+
+## Troubleshooting
+
+### State Pollution Between Scenarios
+
+**Symptom:** Tests pass individually but fail when run together
+
+**Check:**
+1. Are you using struct fields to store state? → Use `ScenarioState` instead
+2. Are database tables being cleaned up? → Verify `CleanupDatabase()` or schema isolation
+3. Are JWT secrets being reset? → Verify `ResetJWTSecrets()` is called
+
+**Debug:** Enable state tracing:
+```bash
+BDD_TRACE_STATE=1 go test ./features/auth -v
+```
+
+### Timeout or Delay Issues
+
+**Symptom:** Config reloading tests fail intermittently
+
+**Cause:** Server monitors config files every 1 second
+
+**Fix:** Add delays >1100ms after config file changes:
+```go
+time.Sleep(1100 * time.Millisecond)  // Wait for monitoring cycle
+```
+
+### Missing Step Definitions
+
+**Symptom:** `undefined step` error
+
+**Check:**
+1. Step is defined in the appropriate `*_steps.go` file
+2. Step is registered in `steps.go`
+3. Step regex matches the feature file text exactly
+4. No typos in the step name
+
+**Tip:** Run with `-v` to see which step is undefined

+This document describes the configuration architecture for BDD tests in the dance-lessons-coach project.
+It establishes a clear hierarchy and flow of configuration parameters to ensure predictable, maintainable,
+and isolated test execution.
+
+## Configuration Sources (Priority Order)
+
+### 1. Explicit Parameters (Highest Priority)
+Passed directly between components with no hidden behavior:
+- `FEATURE`: Which feature is being tested (`greet`, `config`, `auth`, `health`, `jwt`)
+- `GODOG_TAGS`: Scenario tag filters (e.g., `@v2`, `~@flaky`, `~@todo`)
+- `Config` struct: Passed explicitly to server initialization
+
+### 2. Feature-Specific Configuration Files
+Loaded from filesystem when testing specific features:
+- Path: `features/{FEATURE}/{FEATURE}-test-config.yaml`
+- Used by: Config hot-reload tests only
+- Monitored by: `testserver.monitorConfigFile()`
+- Example: `features/config/config-test-config.yaml`
+
+### 3. Environment Variables (External Control Only)
+Set by test scripts and CI/CD, **NOT read deep in implementation code**:
+
+| Variable | Purpose | Default | Set By |
+|----------|---------|---------|-------|
+| `DLC_API_V2_ENABLED` | Enable v2 API globally | `false` | Test scripts |
+| `BDD_SCHEMA_ISOLATION` | Enable per-scenario database schema isolation | `false` | Test scripts, validate-test-suite.sh |
+| `BDD_ENABLE_CLEANUP_LOGS` | Enable detailed cleanup logging | `false` | Test scripts |
+| `BDD_TRACE_STATE` | Enable state tracing | `false` | Test scripts |
+| `FIXED_TEST_PORT` | Use fixed port instead of random | `false` | Test scripts |
+| `FEATURE` | Current feature under test | `""` | testsetup.CreateTestSuite |
+| `GODOG_TAGS` | Tag filter for scenario selection | `"~@flaky && ~@todo && ~@skip"` | CreateTestSuite |
+
+### 4. Hardcoded Defaults (Fallback)
+Used when no other source provides a value:
+- Port: Random in range 10000-19999 (or 9191 if FIXED_TEST_PORT=true)
+- JWT Secret: `test-secret-key-for-bdd-tests`
+- Database: localhost:5432, postgres/postgres, dance_lessons_coach
+- Logging Level: debug
+- v2_enabled: false

+
+## Use Cases
+
+### UC-1: Default Test Run (No v2, No Config File)
+```
+Input:     go test ./features/greet
+FEATURE:   greet
+GODOG_TAGS: ~@flaky && ~@todo && ~@skip
+Config Source: createTestConfig(port)
+v2_enabled: false
+Result: v1 scenarios pass, v2 scenarios skipped by tag filter
+```
+
+### UC-2: v2 API Tests (Split Test Suite)
+```
+Input:     go test ./features/greet (with GODOG_TAGS="@v2" in v2 subtest)
+FEATURE:   greet
+GODOG_TAGS: @v2 && ~@skip
+Config Source: createTestConfig(port) with v2 check
+v2_enabled: true (because FEATURE=greet AND tags contain @v2)
+Result: v2 scenarios execute with v2 API available
+
+Flow:
+1. TestGreetBDD runs v1 subtest with tags="~@v2"
+2. TestGreetBDD runs v2 subtest with tags="@v2"
+3. Each subtest starts its own server
+4. Server in v2 subtest has v2_enabled=true
+5. v2 scenarios pass
+```
+
+### UC-3: Config Hot Reload Tests
+```
+Input:     go test ./features/config
+FEATURE:   config
+GODOG_TAGS: ~@flaky && ~@todo && ~@skip
+Config File: features/config/config-test-config.yaml
+Config Monitor: Watches config file for changes
+
+When config file is modified:
+1. monitorConfigFile() detects file change via mod time
+2. Calls ReloadConfig()
+3. ReloadConfig() for FEATURE=config: loads from config file
+4. Server restarts with new config
+5. Subsequent scenarios see new configuration
+
+Note: This is the ONLY feature that uses config file hot-reload.
+      All other features use hardcoded/test defaults.
+```
+
+### UC-4: Config Hot Reload with v2 Enable
+```
+Scenario: Hot reloading feature flags
+Steps:
+1. Server starts with default config (v2_enabled: false)
+2. Test sets v2_enabled: true in config file
+3. Config monitor detects change
+4. ReloadConfig() called
+5. Server loads from config file (NOT createTestConfig)
+6. Server restarts with v2_enabled: true
+7. Test verifies v2 API works
+
+Current Bug: ReloadConfig() calls createTestConfig() which:
+- Reads FEATURE=config
+- Reads GODOG_TAGS (doesn't contain @v2)
+- Sets v2_enabled: false
+- Overrides the config file setting!
+
+Fix: ReloadConfig() must load from file for config feature.
+```
+
+## Implementation Details
+
+### Config Creation Flow
+
+```go
+// pkg/bdd/testserver/server.go
+
+func NewServer() *Server {
+    port := getRandomPort() // 10000-19999
+    return &Server{port: port}
+}
+
+func (s *Server) Start() error {
+    cfg := createTestConfig(s.port)
+    // ... start server with cfg
+    go s.monitorConfigFile()
+}
+
+// CURRENT - BAD
+func createTestConfig(port int) *config.Config {
+    feature := os.Getenv("FEATURE")
+    tags := os.Getenv("GODOG_TAGS")
+    
+    enableV2 := false
+    if feature == "greet" && strings.Contains(tags, "@v2") {
+        enableV2 = true
+    }
+    // ...
+    return &config.Config{
+        API: config.APIConfig{V2Enabled: enableV2},
+        // ...
+    }
+}
+
+// PROPOSED - GOOD
+func createTestConfig(port int, opts ConfigOptions) *config.Config {
+    defaults := &config.Config{
+        Server: config.ServerConfig{Host: "0.0.0.0", Port: port},
+        // ... all hardcoded defaults
+    }
+    
+    // Apply explicit options (passed from caller)
+    if opts.V2Enabled {
+        defaults.API.V2Enabled = true
+    }
+    
+    return defaults
+}
+
+// ConfigOptions passed from testsuite
+type ConfigOptions struct {
+    V2Enabled      bool
+    UseConfigFile  bool
+    ConfigFilePath string
+}
+```
+
+### Reload Flow Fix
+
+```go
+// pkg/bdd/testserver/server.go
+
+func (s *Server) ReloadConfig() error {
+    feature := os.Getenv("FEATURE")
+    
+    if feature == "config" && s.configFilePath != "" {
+        // For config tests: load from monitored file
+        cfg, err := loadConfigFromFile(s.configFilePath)
+        if err != nil {
+            return err
+        }
+        return s.applyConfig(cfg)
+    }
+    
+    // For all other features: use defaults
+    // (hot reload not supported for non-config features)
+    cfg := createDefaultConfig(s.port)
+    return s.applyConfig(cfg)
+}
+
+func loadConfigFromFile(path string) (*config.Config, error) {
+    v := viper.New()
+    v.SetConfigFile(path)
+    v.SetConfigType("yaml")
+    
+    if err := v.ReadInConfig(); err != nil {
+        return nil, err
+    }
+    
+    var cfg config.Config
+    if err := v.Unmarshal(&cfg); err != nil {
+        return nil, err
+    }
+    
+    // Apply hardcoded values that should NOT come from file
+    // (database connection for BDD tests, etc.)
+    cfg.Database.Host = getDatabaseHost()
+    cfg.Database.Port = getDatabasePort()
+    cfg.Database.User = "postgres"
+    cfg.Database.Password = "postgres"
+    cfg.Database.Name = "dance_lessons_coach"
+    
+    return &cfg, nil
+}
+```
+
+## Configuration File Format
+
+### Config Test File (features/config/config-test-config.yaml)
+```yaml
+server:
+  host: "127.0.0.1"
+  port: 9191
+
+logging:
+  level: "info"
+  json: false
+
+api:
+  v2_enabled: false  # Will be toggled by tests
+
+telemetry:
+  enabled: true
+  sampler:
+    type: "parentbased_always_on"
+    ratio: 1.0
+
+auth:
+  jwt:
+    ttl: 1h
+
+database:
+  # These are OVERRIDDEN by BDD test infrastructure
+  host: "localhost"
+  port: 5432
+  user: "postgres"
+  password: "postgres"
+  name: "dance_lessons_coach_bdd_test"
+  ssl_mode: "disable"
+```
+
+## State Isolation
+
+### Per-Scenario State
+- Managed by: `pkg/bdd/steps/scenario_state.go`
+- Key: SHA256 hash of scenario URI + name
+- State includes: LastToken, FirstToken, LastUserID, LastSecret, LastError
+- Cleared: At start of each scenario in BeforeScenario hook
+
+### Database Schema Isolation
+- Enabled by: `BDD_SCHEMA_ISOLATION=true`
+- Mechanism: Creates unique schema per scenario
+- Schema name: `test_{sha256(scenarioKey)[:8]}`
+- Search path: Set via `SET search_path TO ...`
+- Cleanup: Schema dropped after scenario
+
+### Server-Level State Reset
+- JWT secrets: Reset after every scenario via `ResetJWTSecrets()`
+- Database: Cleaned up after every scenario
+- Auth state: Per-scenario via state manager
+
+## Package Responsibilities
+
+### pkg/bdd/testserver
+- **Purpose**: Test HTTP server management
+- **Responsibilities**:
+  - Server lifecycle (Start, Stop)
+  - Configuration loading and reloading
+  - Database cleanup
+  - Schema isolation
+  - JWT secret management
+  - Config file monitoring (config feature only)
+
+### pkg/bdd/testsetup  
+- **Purpose**: Godog test suite setup
+- **Responsibilities**:
+  - Feature test file discovery
+  - Test suite configuration
+  - Tag filtering
+  - godog options setup
+
+### pkg/bdd/suite
+- **Purpose**: Test suite initialization hooks
+- **Responsibilities**:
+  - BeforeSuite/AfterSuite hooks
+  - BeforeScenario/AfterScenario hooks
+  - Step context creation
+  - State isolation setup
+
+### pkg/bdd/steps
+- **Purpose**: Step definitions
+- **Responsibilities**:
+  - All Gherkin step implementations
+  - Per-scenario state management
+  - Per-feature step organization
+
+## Migration Plan
+
+### Phase 1: Fix Config Reload (Urgent)
+1. Create `loadConfigFromFile()` function
+2. Modify `ReloadConfig()` to use file for config feature
+3. Add tests to verify config hot-reload works
+
+### Phase 2: Clean Up Config Creation
+1. Create `ConfigOptions` struct
+2. Modify `createTestConfig()` to accept options
+3. Update callers to pass explicit options
+4. Remove env var reading from deep in config creation
+
+### Phase 3: Document and Validate
+1. Write comprehensive documentation (this file)
+2. Add validation tests for all use cases
+3. Create troubleshooting guide
+
+### Phase 4: Consider Package Merge (Optional)
+1. Evaluate merging testserver + testsetup
+2. Design new `pkg/bdd/testing` package structure
+3. Migrate code incrementally
+
+## Rules for Adding New Configuration
+
+1. **Prefer explicit parameters** over environment variables
+2. **Read env vars at ONE layer only** (typically test entry point)
+3. **Document all config sources** in this file
+4. **Test config combinations** to prevent override bugs
+5. **Never read env vars in hot paths** (scenario steps, server handlers)
+
+## Troubleshooting
+
+### Symptom: Config file changes not applied
+- Check: Is FEATURE=config?
+- Check: Does config file exist at `features/config/config-test-config.yaml`?
+- Check: Does monitorConfigFile() detect the change?
+- Fix: ReloadConfig() must load from file, not createTestConfig()
+
+### Symptom: v2 tests fail with 404
+- Check: Is FEATURE=greet?
+- Check: Does GODOG_TAGS contain @v2?
+- Check: Does createTestConfig() see the tags?
+- Fix: Ensure tags are set before server creation
+
+### Symptom: State pollution between scenarios
+- Check: Is schema isolation enabled?
+- Check: Are step definitions using per-scenario state?
+- Fix: Use ScenarioState for all mutable state

+# BDD State Tracer
+
+## Overview
+
+The BDD State Tracer is a debugging tool that logs scenario execution, database operations, and state modifications to a file in `$TMPDIR` for analysis of test execution order and state pollution issues.
+
+## Purpose
+
+### Why Tracing Was Added
+
+During multi-iteration BDD test runs with `./scripts/validate-test-suite.sh`, intermittent failures occurred that were difficult to diagnose:
+- Tests passed when run individually
+- Tests failed when run together in the validation script
+- Patterns suggested database state pollution between scenarios across different feature packages
+
+The tracer was created to answer key questions:
+1. **Execution Order**: Which scenarios run in which order?
+2. **State Modifications**: What database writes/cleanups occur and when?
+3. **Overlap Detection**: Are scenarios running in parallel (causing race conditions)?
+4. **Isolation Verification**: Is schema isolation working as expected?
+
+### Key Findings from Tracing
+
+1. **Sequential Execution**: Each feature package runs in a separate process (separate PIDs), but scenarios within each feature run sequentially
+2. **Shared Database**: All processes share the same PostgreSQL database connection
+3. **Schema Isolation Status**: When `BDD_SCHEMA_ISOLATION=false` (default in validate script), all scenarios share the `public` schema
+4. **Cleanup Operations**: Database cleanup (`CleanupDatabase`) runs after each scenario, deleting all test data from all tables
+5. **In-Memory State**: JWT secrets are stored in-memory only, not in database - schema isolation doesn't prevent JWT secret pollution
+
+### Example Trace Output
+
+```
+2026-04-11T10:10:53.032156 | auth            | User registration               | SCENARIO_START   | 
+2026-04-11T10:10:53.146438 | auth            | User registration               | SCENARIO_END     | PASSED
+2026-04-11T10:10:53.152398 | auth            | User registration               | JWT_RESET        | ok
+2026-04-11T10:10:53.162357 | auth            | Failed authentication          | SCENARIO_START   | 
+2026-04-11T10:10:53.268273 | auth            | Failed authentication          | SCENARIO_END     | PASSED
+```
+
+## Usage
+
+### Enable Tracing
+
+Set the environment variable `BDD_TRACE_STATE=1` before running tests:
+
+```bash
+# Single run with tracing
+BDD_TRACE_STATE=1 go test ./features/auth -v
+
+# Validation script with tracing
+BDD_TRACE_STATE=1 ./scripts/validate-test-suite.sh 1
+
+# Multiple runs with tracing
+BDD_TRACE_STATE=1 ./scripts/validate-test-suite.sh 5
+```
+
+### Trace File Location
+
+Trace files are written to `$TMPDIR` (typically `/var/folders/.../T/` on macOS or `/tmp` on Linux):
+
+```bash
+# Find trace files
+ls -la $TMPDIR/bdd-state-trace-*.log
+
+# View a trace file
+cat $TMPDIR/bdd-state-trace-20260411-101053-12345.log
+```
+
+### Trace File Format
+
+```
+TIMESTAMP | FEATURE          | SCENARIO                              | ACTION           | DETAILS
+2026-04-11T10:10:53.032156 | auth            | User registration               | SCENARIO_START   | 
+2026-04-11T10:10:53.146438 | auth            | User registration               | SCENARIO_END     | PASSED
+2026-04-11T10:10:53.152398 | auth            | User registration               | JWT_RESET        | ok
+2026-04-11T10:10:53.162357 | auth            | User registration               | DB_CLEANUP       | all_tables
+```
+
+**Columns:**
+- `TIMESTAMP`: ISO 8601 format with microseconds
+- `FEATURE`: Feature name from `FEATURE` environment variable
+- `SCENARIO`: Scenario name (includes URI for disambiguation)
+- `ACTION`: Type of action (see below)
+- `DETAILS`: Additional context
+
+**Action Types:**
+- `SCENARIO_START` - Scenario execution begins
+- `SCENARIO_END` - Scenario execution completes (PASSED or FAILED)
+- `DB_CLEANUP` - Database cleanup operation
+- `DB_SELECT` - Database read operation
+- `JWT_RESET` - JWT secrets reset to initial state
+- `DB_INSERT/UPDATE/DELETE` - Database write operations (future)
+- `SCHEMA_*` - Schema isolation operations (future)
+- `TX_*` - Transaction boundary operations (future)
+
+## Implementation
+
+### Architecture
+
+The state tracer uses a simple file-based approach:
+
+1. **Per-Process Tracing**: Each `go test` process creates its own trace file with unique filename based on timestamp and PID
+2. **Immediate Flush**: Each trace line is flushed immediately to disk using `Sync()` to prevent data loss
+3. **No Dependencies**: Uses only standard library (`os`, `fmt`, `time`, `path/filepath`)
+4. **Singleton Pattern**: Package-level functions for easy usage across the codebase
+
+### Files
+
+- `pkg/bdd/testserver/state_tracer.go` - Core tracing functions
+- `pkg/bdd/suite.go` - Integration with godog Before/After scenario hooks
+
+### Key Functions
+
+```go
+// Package-level functions (called from anywhere)
+TraceStateScenarioStart(feature, scenario string)
+TraceStateScenarioEnd(feature, scenario string, err error)
+TraceStateDBCleanup(feature, scenario, table string)
+TraceStateJWTSecretOperation(feature, scenario, operation, details string)
+TraceStateSchemaIsolation(feature, scenario, operation, details string)
+TraceStateTransaction(feature, scenario, action, details string)
+TraceStateDBRead(feature, scenario, table, details string)
+```
+
+## Limitations
+
+### Current Limitations
+
+1. **Per-Process Files**: Each `go test` process creates its own file, making correlation across processes manual
+2. **No Database Write Tracing**: Currently only traces cleanup, not individual INSERT/UPDATE/DELETE operations
+3. **No API Call Tracing**: Doesn't trace HTTP requests made during scenarios
+4. **No Timing Analysis**: Doesn't measure duration between operations automatically
+5. **No Schema Name in Trace**: When schema isolation is enabled, doesn't show which schema is active
+6. **File Rotation**: No automatic cleanup of old trace files
+
+### Known Issues
+
+1. **PID-based filenames**: If multiple runs happen in the same second, filenames could collide
+2. **Large file sizes**: High-volume tracing could create large files (mitigated by per-run files)
+3. **No header/footer**: Trace files start immediately with data, no metadata about the run
+
+## Future Enhancements
+
+### Priority 1: Process Correlation
+- Add a unique run ID that can be passed across all processes
+- Include process start/end markers to show process lifecycle
+- Add parent PID tracking to show process hierarchy
+
+### Priority 2: Database Operation Tracing
+- Add tracing for all database writes (INSERT, UPDATE, DELETE)
+- Include query text and affected rows
+- Trace transaction boundaries with IDs
+- Add schema name to all database operations when isolation is enabled
+
+### Priority 3: API Call Tracing
+- Trace all HTTP requests made during scenarios
+- Include request method, path, status code, and duration
+- Mark requests that modify state (POST, PUT, DELETE vs GET)
+
+### Priority 4: Analysis Tools
+- Create a `bdd-trace-analyzer` tool to:
+  - Merge trace files from all processes in correct order
+  - Detect overlapping scenarios (parallel execution)
+  - Identify database state pollution patterns
+  - Generate visualization of scenario execution timeline
+  - Flag potential race conditions
+
+### Priority 5: Improved Output
+- Add trace file header with metadata (run ID, start time, config, etc.)
+- Color-coded output for different action types
+- JSON output option for programmatic analysis
+- Trace level filtering (DEBUG, INFO, WARN, ERROR)
+
+### Priority 6: Performance Optimization
+- Batch writes instead of per-line flush (with configurable flush interval)
+- Compress old trace files
+- Automatic cleanup of old files
+
+## Analysis Use Cases
+
+### Detecting State Pollution
+
+Look for patterns like:
+```
+PID 1234 | auth | Scenario A | DB_CLEANUP | all_tables
+PID 5678 | greet | Scenario B | SCENARIO_START |
+# ^ Scenario B starts AFTER auth cleanup - potential issue
+```
+
+### Detecting Parallel Execution
+
+Check if timestamps overlap:
+```
+PID 1234 | 10:10:53.032 | auth | Scenario A | SCENARIO_START
+PID 5678 | 10:10:53.035 | greet | Scenario B | SCENARIO_START
+# ^ Both started within 3ms - likely parallel
+```
+
+### Verifying Schema Isolation
+
+Check that each scenario gets its own schema:
+```
+PID 1234 | auth | Scenario A | SCHEMA_CREATE | test_a1b2c3d4
+PID 1234 | auth | Scenario B | SCHEMA_CREATE | test_e5f6g7h8
+# ^ Different schemas for different scenarios - good
+```
+
+## Troubleshooting
+
+### Tracing Not Working
+
+1. Verify `BDD_TRACE_STATE=1` is set:
+   ```bash
+   echo $BDD_TRACE_STATE
+   ```
+2. Check if trace files are being created:
+   ```bash
+   ls -la $TMPDIR/bdd-state-trace-*.log
+   ```
+3. Verify the `testserver` package is being used (tracing is integrated there)
+
+### No Trace Files Found
+
+- Tracing only works when `BDD_TRACE_STATE=1` is set before the test process starts
+- Each `go test` process creates its own file - if tests pass quickly, files may be short
+- Files are created in `$TMPDIR` which defaults to `/tmp` on Linux and a temp folder on macOS
+
+### Trace Files Too Large
+
+- Tracing every operation can generate large files
+- Consider filtering to specific scenarios:
+  ```bash
+  # Run only failing scenarios with tracing
+  BDD_TRACE_STATE=1 go test ./features/auth -v -run "TestAuthBDD/Password_reset"
+  ```
