🔀 merge: integrate origin/main (PR #16 JSON logging fix) into restructure branch

PR #16 (commit c17fb4f) introduced 2 things while this restructure branch
was in flight:
1. A fix in pkg/config/config.go (peekJSONLogging) so the very first log
   line is JSON when DLC_LOGGING_JSON=true.
2. Its own attempt to shorten AGENTS.md (1296 → 191 lines).

Resolution:
- Code/scripts changes from #16 (config.go, server.go, scripts/*,
  gitea-client.sh) accepted as-is via auto-merge.
- AGENTS.md conflict resolved by keeping our version (130 lines,
  fully externalized to documentation/*.md). Our approach goes further
  in the lazy-loading direction (D-004, 128k context constraint),
  externalizing every detail instead of keeping minimal inline content.

Caught up the missing /api/version endpoint in documentation/API.md
(commit acebea3 just before this merge) so we don't regress on the
new endpoint introduced by #16.

Pre-commit hooks already validated each upstream commit. Re-running
on the merge to confirm.

+# CI/CD Workflow Architecture
+
+## 🗺️ Overview
+
+The dance-lessons-coach project uses a **multi-workflow architecture** for better separation of concerns, maintainability, and flexibility.
+
+## 📁 Workflow Files
+
+### 1. `ci-cd.yaml` - Main CI/CD Pipeline
+
+**Purpose**: Run tests, build binaries, and generate documentation
+
+**Triggers**:
+- Push to `main`, `ci/**`, `feature/**`, `fix/**`, `refactor/**` branches
+- Pull requests to `main` branch
+- Manual workflow dispatch
+
+**Jobs**:
+1. **build-cache** - Build and cache Docker build environment
+2. **ci-pipeline** - Run tests, build binaries, generate Swagger docs
+3. **trigger-docker-push** - Trigger separate Docker workflow on main branch
+
+**Key Features**:
+- Runs in container environment with all build tools
+- Generates Swagger documentation
+- Runs BDD and unit tests with PostgreSQL
+- Updates badges and version information
+- Triggers Docker workflow only on main branch
+
+### 2. `docker-push.yaml` - Docker Image Publishing
+
+**Purpose**: Build and push Docker images to registry
+
+**Triggers**:
+- Manual workflow dispatch only (no automatic triggers)
+- Triggered by `ci-cd.yaml` on main branch
+
+**Jobs**:
+1. **docker-push** - Build production Docker image and push to registry
+
+**Key Features**:
+- Runs on host environment (access to Docker daemon)
+- Uses dependency hash from build-cache
+- Builds minimal Alpine-based production image
+- Pushes multiple tags (version, latest, commit SHA)
+
+## 🔧 Architecture Benefits
+
+### 1. Clear Separation of Concerns
+- **CI/CD Pipeline**: Testing and artifact generation
+- **Docker Publishing**: Image building and registry operations
+
+### 2. Proper Environment Isolation
+- **CI jobs run in container**: Consistent build environment
+- **Docker jobs run on host**: Access to Docker daemon
+
+### 3. Flexible Testing
+- Can trigger Docker workflow independently for testing
+- No complex conditional logic in main workflow
+- Easier to debug and maintain
+
+### 4. Better Security
+- Docker operations isolated in separate workflow
+- Clear dependency between test success and deployment
+- Manual trigger capability for emergency situations
+
+## 🚀 Usage Examples
+
+### Trigger Full CI/CD Pipeline
+```bash
+# Automatically triggered on push to main branch
+# Or manually:
+./scripts/gitea-client.sh trigger-workflow arcodange dance-lessons-coach ci-cd.yaml main
+```
+
+### Trigger Docker Push Manually
+```bash
+# Get dependency hash from build-cache job first
+DEPS_HASH="abc123def456"
+
+# Trigger Docker workflow manually
+./scripts/gitea-client.sh trigger-workflow arcodange dance-lessons-coach docker-push.yaml main --deps_hash $DEPS_HASH
+```
+
+### Workflow Dispatch Parameters (docker-push.yaml)
+- `deps_hash` (required): Dependency hash from build-cache job
+- `ref` (optional): Git reference (branch/tag), defaults to current
+
+## 🔗 Workflow Dependencies
+
+```mermaid
+graph TD
+    A[Push to main] --> B[ci-cd.yaml]
+    B --> C[build-cache job]
+    B --> D[ci-pipeline job]
+    D --> E[trigger-docker-push job]
+    E --> F[docker-push.yaml]
+    F --> G[docker-push job]
+    G --> H[Docker Registry]
+```
+
+## 📋 Best Practices
+
+### 1. Always Run CI First
+- Docker workflow should only be triggered after CI passes
+- Maintains quality gate before deployment
+
+### 2. Use Dependency Hash
+- Ensures consistent builds across workflows
+- Pass hash from build-cache to docker-push
+
+### 3. Manual Testing
+- Use separate Docker workflow for testing image builds
+- Avoids polluting main branch with test images
+
+### 4. Monitor Both Workflows
+- CI/CD workflow for test results and artifacts
+- Docker workflow for image build and push status
+
+## 🎯 Docker Build Strategy Decision
+
+### 🏆 Chosen Approach: Attempt 2 (Standard Dockerfile)
+
+After extensive testing of multiple approaches, we selected **Attempt 2** as the optimal Docker build strategy.
+
+#### ⚡ Why Attempt 2 Won:
+
+**1. Simplicity (60% smaller workflow)**
+- 73 lines vs 158 lines in complex approaches
+- No inline Dockerfile generation
+- Standard `docker build -f docker/Dockerfile .` command
+
+**2. Better Performance**
+- No artifact/cache action overhead
+- Natural Docker layer caching works optimally
+- Faster execution without complex variable substitutions
+
+**3. Superior Reliability**
+- Proven standard Docker build process
+- Easier to debug and maintain
+- Fewer moving parts = fewer failures
+
+**4. Better Maintainability**
+- Uses standard Dockerfile (easier to understand)
+- No complex YAML templating
+- Clear separation of concerns
+
+#### 🗑️ Why We Rejected Other Approaches:
+
+**Attempt 1 (Inline Dockerfile):**
+- Complex YAML templating
+- Harder to debug and maintain
+- No significant performance benefit
+
+**Attempt 3 (Build Cache Image):**
+- Added complexity with cache management
+- Slower due to artifact actions overhead
+- More prone to cache invalidation issues
+
+**Attempt 4 (Template File):**
+- Added unnecessary file management
+- No clear advantage over standard Dockerfile
+- More complex workflow
+
+### 📊 Performance Comparison:
+
+| Approach | Lines of Code | Complexity | Reliability | Maintainability |
+|----------|---------------|------------|-------------|-----------------|
+| **Attempt 2** | 73 | Low | High | Excellent |
+| Attempt 1 | 158 | High | Medium | Poor |
+| Attempt 3 | 125 | Medium | Medium | Fair |
+| Attempt 4 | 110 | Medium | High | Good |
+
+### 🔧 Implementation Details:
+
+**Standard Dockerfile Approach:**
+```yaml
+- name: Build and push Docker image
+  run: |
+    docker build -t dance-lessons-coach -f docker/Dockerfile .
+    docker tag dance-lessons-coach "$IMAGE_NAME"
+    docker push "$IMAGE_NAME"
+```
+
+**Key Benefits:**
+- Uses multi-stage builds for optimization
+- Standard Docker layer caching works naturally
+- Easy to understand and modify
+- Proven reliability in production
+
+## 🎯 Future Enhancements
+
+### Potential Improvements:
+- Add workflow status badges to README
+- Implement workflow chaining with outputs
+- Add matrix builds for multiple architectures
+- Implement canary deployment workflow
+- Add rollback capability
+
+### Architecture Considerations:
+- Keep workflows focused on single responsibilities
+- Maintain clear separation between test and deploy
+- Document all workflow triggers and conditions
+- Monitor workflow execution times and optimize
+
+## 📝 Maintenance
+
+### Adding New Jobs:
+- Add to appropriate workflow based on responsibility
+- CI-related jobs → `ci-cd.yaml`
+- Docker-related jobs → `docker-push.yaml`
+
+### Modifying Triggers:
+- Update trigger conditions in respective workflow files
+- Test changes thoroughly before merging
+
+### Debugging:
+- Check workflow logs in Gitea Actions
+- Use `gitea-client.sh diagnose-job` for detailed analysis
+- Monitor workflow dependencies and execution order
+
+## 🔒 Security
+
+### Secrets Management:
+- Docker registry credentials stored in Gitea secrets
+- Never hardcode credentials in workflow files
+- Use GitHub token for workflow dispatch
+
+### Access Control:
+- Only authorized users can trigger workflows
+- Manual approval required for production deployments
+- Audit logs available for all workflow executions
+
+This architecture provides a clean, maintainable, and secure CI/CD pipeline that scales well with project growth while maintaining clear separation of concerns.

-## CI/CD Pipeline
-
-dance-lessons-coach features an optimized CI/CD pipeline using GitHub Actions with container/services architecture:
-
-### Key Features
-- ✅ **Container-based execution**: All steps run in pre-built Docker cache images
-- ✅ **Service-based PostgreSQL**: Automatic database service provisioning
-- ✅ **Smart caching**: Dependency-aware cache invalidation
-- ✅ **Multi-platform**: Compatible with Gitea, GitHub, and GitLab
-- ✅ **Fast execution**: No Docker Compose overhead
-- ✅ **Reliable testing**: Full database connectivity with proper environment setup
-
-### Architecture
-
-The pipeline uses GitHub Actions' native `container` and `services` directives instead of Docker Compose:
-
-```yaml
-jobs:
-  ci-pipeline:
-    container:
-      image: gitea.arcodange.lab/arcodange/dance-lessons-coach-build-cache:${{ needs.build-cache.outputs.deps_hash }}
-    
-    services:
-      postgres:
-        image: postgres:15
-        env:
-          POSTGRES_USER: postgres
-          POSTGRES_PASSWORD: postgres
-          POSTGRES_DB: dance_lessons_coach_bdd_test
-```
-
-### Benefits
-
-1. **Performance**: Direct container execution without compose overhead
-2. **Reliability**: Service containers managed by GitHub Actions
-3. **Simplicity**: Cleaner workflow definition
-4. **Portability**: Works across CI platforms
-5. **Caching**: Intelligent dependency-based cache rebuilding
-
-### Workflow Steps
-
-1. **Build Cache**: Creates Docker image with Go tools and dependencies
-2. **CI Pipeline**: Runs tests, builds binaries, and generates documentation
-3. **Database Tests**: Connects to PostgreSQL service container
-4. **Coverage Reporting**: Updates coverage badges automatically
-5. **Artifact Publishing**: Builds and pushes Docker images (main branch only)
-
-### Environment Configuration
-
-The pipeline automatically sets up database environment variables:
-
 ```bash
-echo "DLC_DATABASE_HOST=postgres" >> $GITHUB_ENV
-echo "DLC_DATABASE_PORT=5432" >> $GITHUB_ENV
-echo "DLC_DATABASE_USER=postgres" >> $GITHUB_ENV
-echo "DLC_DATABASE_PASSWORD=postgres" >> $GITHUB_ENV
-echo "DLC_DATABASE_NAME=dance_lessons_coach_bdd_test" >> $GITHUB_ENV
-echo "DLC_DATABASE_SSL_MODE=disable" >> $GITHUB_ENV
+curl http://localhost:8080/api/health

-
-## Development
-
-### Generate OpenAPI Documentation
-
-The project uses [swaggo/swag](https://github.com/swaggo/swag) to generate OpenAPI/Swagger documentation from code annotations:
-
-```bash
-# Generate documentation
-go generate ./pkg/server/
-
-# This creates:
-# - pkg/server/docs/docs.go (swagger template)
-# - pkg/server/docs/swagger.json (OpenAPI spec)
-# - pkg/server/docs/swagger.yaml (YAML version)
-```
-
-**Note:** `pkg/server/docs/` is gitignored. Documentation is embedded in the binary at build time.
-
-### Documentation Annotations
-
-Add swagger annotations to handlers and models:
-
-```go
-// @Summary Get personalized greeting
-// @Description Returns a greeting with the specified name
-// @Tags greet
-// @Accept json
-// @Produce json
-// @Param name path string true "Name to greet"
-// @Success 200 {object} GreetResponse "Successful response"
-// @Failure 400 {object} ErrorResponse "Invalid name parameter"
-// @Router /v1/greet/{name} [get]
-func (h *apiV1GreetHandler) handleGreetPath(w http.ResponseWriter, r *http.Request) {
-    // handler implementation
-}
-```

However, the flat `features/` layout and single `steps.go` file described here were replaced by a modular per-domain structure. See ADR-0024 for the current organisation: `features/{auth,greet,health,jwt,config}/` with domain-specific step files and per-domain `*_test.go` runners.

That second layer was deferred and has no concrete plan. The actual architecture is **BDD direct-HTTP testing + OpenAPI documentation via swaggo** — calling it "hybrid" is misleading. SDK generation remains a possible future enhancement but is not tracked by any open issue.

+
+* Status: Accepted
+* Deciders: Gabriel Radureau, AI Agent
+* Date: 2026-04-05
+* Implementation Date: 2026-04-05
+
+## Context and Problem Statement
+
+The dance-lessons-coach application needs input validation for API request bodies and configuration values. We need a library that integrates well with Go structs and provides clear error messages.
+
+## Decision Drivers
+
+* Struct-tag-based validation to avoid boilerplate
+* Good error messages with field-level detail
+* Active maintenance and wide adoption
+* Compatibility with existing interface-based design
+
+## Considered Options
+
+* `github.com/go-playground/validator/v10` — struct-tag driven, widely adopted
+* `github.com/asaskevich/govalidator` — tag-based but less expressive
+* Manual validation — full control, no dependency, high boilerplate
+
+## Decision Outcome
+
+Chosen option: **`go-playground/validator/v10`** because it is the de-facto standard in the Go ecosystem, supports struct-tag annotations, provides field-level error detail, and integrates cleanly with our interface-based design.
+
+## Implementation
+
+`github.com/go-playground/validator/v10 v10.30.2` is present in `go.mod`.
+The `pkg/validation/` package wraps the validator for reuse across handlers.

+# 14. gRPC Adoption Strategy
+
+* Status: Rejected / Deferred
+* Deciders: Gabriel Radureau, AI Agent
+* Date: 2026-04-05
+
+## Context and Problem Statement
+
+As the API grows, gRPC was evaluated as an alternative or complement to REST for internal service communication. The question was whether to adopt gRPC alongside the existing Chi REST API.
+
+## Decision Drivers
+
+* Performance of inter-service communication
+* Type safety via Protocol Buffers
+* Streaming support
+* Team familiarity and operational overhead
+
+## Considered Options
+
+* **Hybrid REST/gRPC** — add gRPC endpoints alongside existing REST endpoints
+* **REST only** — maintain current Chi router approach
+* **gRPC-first with transcoding** — use bufbuild/connect for unified REST+gRPC
+
+## Decision Outcome
+
+Chosen option: **REST only (deferred)**. gRPC adoption is not warranted at the current scale. The application has a small number of endpoints, a single-binary deployment model, and no internal service mesh that would benefit from gRPC's efficiency.
+
+### Reasons for deferral
+
+1. **No inter-service communication today** — the application is a single binary; gRPC's main benefit (efficient binary RPC between services) does not apply
+2. **Complexity cost** — adding Protobuf toolchain, code generation, and a second transport layer would significantly increase cognitive overhead
+3. **Chi router commitment** — the REST API is well-designed with OpenAPI documentation; introducing gRPC in parallel creates dual-maintenance burden
+4. **Team capacity** — limited bandwidth for large architectural changes
+
+## When to reconsider
+
+* Application evolves into multiple services that need efficient internal RPC
+* Streaming use cases emerge (real-time lesson progress, etc.)
+* External consumers explicitly require gRPC endpoints

+> **Note:** Basic JWT multi-secret support and graceful rotation are implemented in `pkg/jwt/jwt_secret_manager.go`. The retention cleanup policy (background job, configurable TTL factor) proposed in this ADR is **not yet implemented**.
+
+## Context
+
+The dance-lessons-coach application requires a robust JWT secret management system that balances security and user experience. The system supports multiple JWT secrets for graceful rotation. However, the current implementation lacks a clear policy for secret retention and cleanup.
+
+### Current State
+
+- ✅ Multiple JWT secrets supported
+- ✅ Graceful rotation implemented
+- ✅ Backward compatibility maintained
+- ❌ No automatic cleanup of old secrets
+- ❌ No configurable retention periods
+- ❌ No expiration-based secret management
+
+### Problem Statement
+
+Without a retention policy:
+1. **Security Risk**: Old secrets accumulate indefinitely, increasing attack surface
+2. **Memory Bloat**: Unbounded growth of secret storage
+3. **Operational Overhead**: Manual cleanup required
+4. **Compliance Issues**: May violate security policies requiring regular key rotation
+
+### Requirements
+
+1. **Configurable Retention**: Administrators should control how long secrets are retained
+2. **Automatic Cleanup**: System should automatically remove expired secrets
+3. **Backward Compatibility**: Existing tokens should continue working during retention period
+4. **Sensible Defaults**: Should work out-of-the-box with secure defaults
+5. **Performance**: Cleanup should not impact runtime performance
+
+## Decision
+
+### JWT Secret Retention Policy
+
+Implement a configurable retention policy based on JWT TTL (Time-To-Live) with the following components:
+
+#### 1. Configuration Structure
+
+```yaml
+jwt:
+  # Token time-to-live (default: 24h)
+  ttl: 24h
+
+  # Secret retention configuration
+  secret_retention:
+    # Retention factor multiplier (default: 2.0)
+    # Retention period = JWT TTL × retention_factor
+    retention_factor: 2.0
+
+    # Maximum retention period (safety limit, default: 72h)
+    max_retention: 72h
+
+    # Cleanup frequency for expired secrets (default: 1h)
+    cleanup_interval: 1h
+```
+
+#### 2. Retention Period Calculation
+
+```
+retention_period = min(JWT_TTL × retention_factor, max_retention)
+```
+
+**Examples:**
+- Default (24h TTL, 2.0 factor): `min(48h, 72h) = 48h`
+- Short-lived tokens (1h TTL, 3.0 factor): `min(3h, 72h) = 3h`
+- Long-lived tokens (72h TTL, 2.0 factor): `min(144h, 72h) = 72h`
+
+#### 3. Secret Lifecycle
+
+```mermaid
+graph LR
+    A[Secret Created] --> B[Active Period]
+    B --> C{Retention Period}
+    C -->|Expired| D[Marked for Cleanup]
+    C -->|Valid| B
+    D --> E[Automatic Removal]
+```
+
+#### 4. Cleanup Process
+
+- **Frequency**: Configurable interval (default: 1 hour)
+- **Scope**: Remove secrets older than retention period
+- **Safety**: Never remove current primary secret
+- **Logging**: Audit trail of cleanup operations
+
+### Implementation Strategy
+
+#### Phase 1: Configuration Framework
+
+1. **Extend Config Package** (`pkg/config/config.go`)
+   - Add JWT TTL configuration
+   - Add secret retention parameters
+   - Implement validation
+
+2. **Environment Variables**
+   ```bash
+   # JWT Token TTL
+   DLC_JWT_TTL=24h
+
+   # Secret Retention
+   DLC_JWT_SECRET_RETENTION_FACTOR=2.0
+   DLC_JWT_SECRET_MAX_RETENTION=72h
+   DLC_JWT_SECRET_CLEANUP_INTERVAL=1h
+   ```
+
+#### Phase 2: Secret Manager Enhancement
+
+1. **Enhance JWTSecret Struct**
+   ```go
+   type JWTSecret struct {
+       Secret     string
+       IsPrimary  bool
+       CreatedAt  time.Time
+       ExpiresAt  *time.Time  // Now properly calculated
+       RetentionPeriod time.Duration
+   }
+   ```
+
+2. **Add Expiration Logic**
+   ```go
+   func (m *JWTSecretManager) AddSecret(secret string, isPrimary bool, expiresIn time.Duration) {
+       // Calculate retention period based on config
+       retentionPeriod := m.calculateRetentionPeriod()
+       expiresAt := time.Now().Add(expiresIn)
+       
+       m.secrets = append(m.secrets, JWTSecret{
+           Secret:        secret,
+           IsPrimary:     isPrimary,
+           CreatedAt:     time.Now(),
+           ExpiresAt:     &expiresAt,
+           RetentionPeriod: retentionPeriod,
+       })
+   }
+   ```
+
+#### Phase 3: Automatic Cleanup
+
+1. **Background Cleanup Job**
+   ```go
+   func (m *JWTSecretManager) StartCleanupJob(ctx context.Context, interval time.Duration) {
+       ticker := time.NewTicker(interval)
+       go func() {
+           for {
+               select {
+               case <-ticker.C:
+                   m.CleanupExpiredSecrets()
+               case <-ctx.Done():
+                   ticker.Stop()
+                   return
+               }
+           }
+       }()
+   }
+   ```
+
+2. **Cleanup Implementation**
+   ```go
+   func (m *JWTSecretManager) CleanupExpiredSecrets() {
+       now := time.Now()
+       var activeSecrets []JWTSecret
+       
+       for _, secret := range m.secrets {
+           if secret.IsPrimary {
+               // Never remove current primary
+               activeSecrets = append(activeSecrets, secret)
+               continue
+           }
+           
+           // Check if secret is within retention period
+           if now.Sub(secret.CreatedAt) <= secret.RetentionPeriod {
+               activeSecrets = append(activeSecrets, secret)
+           } else {
+               log.Info().
+                   Str("secret", secret.Secret).
+                   Msg("Removed expired JWT secret")
+           }
+       }
+       
+       m.secrets = activeSecrets
+   }
+   ```
+
+#### Phase 4: Integration
+
+1. **Server Initialization**
+   ```go
+   func (s *Server) InitializeJWT() error {
+       // Load config
+       jwtConfig := s.config.GetJWTConfig()
+       
+       // Create secret manager with retention policy
+       secretManager := NewJWTSecretManager(
+           jwtConfig.Secret,
+           WithRetentionFactor(jwtConfig.RetentionFactor),
+           WithMaxRetention(jwtConfig.MaxRetention),
+       )
+       
+       // Start cleanup job
+       secretManager.StartCleanupJob(s.ctx, jwtConfig.CleanupInterval)
+       
+       return nil
+   }
+   ```
+
+### Validation
+
+#### 1. Configuration Validation
+
+```go
+func (c *Config) ValidateJWTConfig() error {
+    if c.JWT.TTL <= 0 {
+        return fmt.Errorf("jwt.ttl must be positive")
+    }
+    
+    if c.JWT.SecretRetention.RetentionFactor < 1.0 {
+        return fmt.Errorf("jwt.secret_retention.retention_factor must be ≥ 1.0")
+    }
+    
+    if c.JWT.SecretRetention.MaxRetention <= 0 {
+        return fmt.Errorf("jwt.secret_retention.max_retention must be positive")
+    }
+    
+    if c.JWT.SecretRetention.CleanupInterval <= 0 {
+        return fmt.Errorf("jwt.secret_retention.cleanup_interval must be positive")
+    }
+    
+    // Ensure max retention is reasonable
+    if c.JWT.SecretRetention.MaxRetention > 720h { // 30 days
+        return fmt.Errorf("jwt.secret_retention.max_retention exceeds maximum of 720h")
+    }
+    
+    return nil
+}
+```
+
+#### 2. Runtime Validation
+
+```go
+func (m *JWTSecretManager) ValidateSecret(secret string) error {
+    // Check minimum length
+    if len(secret) < 16 {
+        return fmt.Errorf("jwt secret must be at least 16 characters")
+    }
+    
+    // Check entropy (basic check)
+    if !hasSufficientEntropy(secret) {
+        return fmt.Errorf("jwt secret must have sufficient entropy")
+    }
+    
+    return nil
+}
+```
+
+### Monitoring and Observability
+
+#### 1. Metrics
+
+```go
+// Prometheus metrics
+var (
+    jwtSecretsActive = prometheus.NewGauge(prometheus.GaugeOpts{
+        Name: "jwt_secrets_active_count",
+        Help: "Number of active JWT secrets",
+    })
+    
+    jwtSecretsExpired = prometheus.NewCounter(prometheus.CounterOpts{
+        Name: "jwt_secrets_expired_total",
+        Help: "Total number of expired JWT secrets removed",
+    })
+    
+    jwtSecretRetentionDuration = prometheus.NewHistogram(prometheus.HistogramOpts{
+        Name: "jwt_secret_retention_duration_seconds",
+        Help: "Duration of JWT secret retention periods",
+        Buckets: prometheus.ExponentialBuckets(3600, 2, 6), // 1h to 32h
+    })
+)
+```
+
+#### 2. Logging
+
+```go
+func (m *JWTSecretManager) logSecretEvent(secret string, event string, details ...interface{}) {
+    log.Info().
+        Str("secret", maskSecret(secret)).
+        Str("event", event).
+        Interface("details", details).
+        Msg("JWT secret event")
+}
+
+func maskSecret(secret string) string {
+    if len(secret) <= 4 {
+        return "****"
+    }
+    return secret[:4] + "****" + secret[len(secret)-4:]
+}
+```
+
+## Consequences
+
+### Positive
+
+1. **Enhanced Security**: Automatic cleanup reduces attack surface
+2. **Reduced Memory Usage**: Prevents unbounded growth of secret storage
+3. **Operational Efficiency**: No manual cleanup required
+4. **Compliance Ready**: Meets security policy requirements for key rotation
+5. **Flexibility**: Configurable to meet different security requirements
+
+### Negative
+
+1. **Complexity**: Adds configuration and cleanup logic
+2. **Performance Overhead**: Background cleanup job (minimal impact)
+3. **Migration**: Existing deployments need configuration updates
+4. **Debugging**: More moving parts to troubleshoot
+
+### Neutral
+
+1. **Backward Compatibility**: Existing tokens continue to work
+2. **Learning Curve**: New configuration options to understand
+3. **Monitoring**: Additional metrics to track
+
+## Alternatives Considered
+
+### Alternative 1: Fixed Retention Period
+
+**Proposal**: Use fixed retention period (e.g., 48 hours) instead of TTL-based calculation
+
+**Rejected Because**:
+- Less flexible for different use cases
+- Doesn't scale with JWT TTL changes
+- May be too short for long-lived tokens or too long for short-lived ones
+
+### Alternative 2: Manual Cleanup Only
+
+**Proposal**: Require administrators to manually clean up old secrets
+
+**Rejected Because**:
+- Operational overhead
+- Security risk if cleanup is forgotten
+- Doesn't scale for frequent rotations
+
+### Alternative 3: No Retention (Current State)
+
+**Proposal**: Keep current behavior with no automatic cleanup
+
+**Rejected Because**:
+- Security concerns with accumulating secrets
+- Memory management issues
+- Compliance violations
+
+## Success Metrics
+
+1. **Security**: No old secrets remain beyond retention period
+2. **Reliability**: 99.9% of valid tokens continue to work during rotation
+3. **Performance**: Cleanup job completes in <100ms with <1000 secrets
+4. **Adoption**: Configuration used in 100% of deployments within 3 months
+

+## Appendix
+
+### Configuration Examples
+
+**Development Environment** (short retention for testing):
+```yaml
+jwt:
+  ttl: 1h
+  secret_retention:
+    retention_factor: 1.5
+    max_retention: 3h
+    cleanup_interval: 30m
+```
+
+**Production Environment** (secure defaults):
+```yaml
+jwt:
+  ttl: 24h
+  secret_retention:
+    retention_factor: 2.0
+    max_retention: 72h
+    cleanup_interval: 1h
+```
+
+**High-Security Environment** (aggressive rotation):
+```yaml
+jwt:
+  ttl: 8h
+  secret_retention:
+    retention_factor: 1.5
+    max_retention: 24h
+    cleanup_interval: 30m
+```
+
+### Troubleshooting
+
+**Issue**: Secrets being removed too quickly
+- **Check**: Retention factor and JWT TTL settings
+- **Fix**: Increase retention_factor or JWT TTL
+
+**Issue**: Too many old secrets accumulating
+- **Check**: Cleanup job logs and interval
+- **Fix**: Decrease cleanup_interval or retention_factor
+
+**Issue**: Performance degradation during cleanup
+- **Check**: Number of secrets and cleanup frequency
+- **Fix**: Optimize cleanup algorithm or increase interval
+
+### FAQ
+
+**Q: What happens to tokens signed with expired secrets?**
+A: Tokens signed with expired secrets will be rejected during validation, requiring users to re-authenticate.
+
+**Q: Can I disable automatic cleanup?**
+A: Yes, set `cleanup_interval` to a very high value (e.g., `8760h` for 1 year).
+
+**Q: How does this affect existing deployments?**
+A: Existing deployments will use sensible defaults. The feature is backward compatible.
+
+**Q: What's the recommended retention factor?**
+A: Start with 2.0 (2× JWT TTL) and adjust based on your security requirements and user experience needs.
+
+**Q: How often should cleanup run?**
+A: For most deployments, every 1 hour is sufficient. High-volume systems may need more frequent cleanup.

+# ADR 0022: Rate Limiting and Cache Strategy
+
+## Status
+**Proposed** 🟡
+
+> **⚠️ Not yet implemented.** Gitea issue #13 ("feat: Implement Rate Limiting and Caching Strategy") is open and tracks this work. `go-cache`, `redis`, and `ulule/limiter` are absent from `go.mod`. The phase checkboxes below are corrected to reflect actual status.
+
+## Context
+
+As the dance-lessons-coach application grows and potentially serves multiple users simultaneously, we need to implement rate limiting to:
+
+1. **Prevent abuse** of API endpoints
+2. **Protect against DDoS attacks**
+3. **Ensure fair usage** across all users
+4. **Maintain system stability** under load
+5. **Provide consistent performance**
+
+Additionally, we need a caching strategy to:
+1. **Reduce database load** for frequently accessed data
+2. **Improve response times** for common requests
+3. **Support horizontal scaling** with shared cache
+4. **Handle cache invalidation** properly
+
+## Decision
+
+We will implement a **multi-phase caching and rate limiting strategy** with the following components:
+
+### Phase 1: In-Memory Cache with TTL Support
+
+**Library Selection**: We will use **`github.com/patrickmn/go-cache`** for in-memory caching because:
+
+✅ **Pros:**
+- Simple, lightweight, and well-maintained
+- Built-in TTL (Time-To-Live) support
+- Thread-safe by default
+- No external dependencies
+- Good performance for single-instance applications
+- Supports automatic expiration
+
+❌ **Cons:**
+- Not shared between multiple instances
+- Memory-bound (not persistent)
+- Limited advanced features
+
+**Implementation Plan:**
+```go
+type CacheService interface {
+    Set(key string, value interface{}, expiration time.Duration) error
+    Get(key string) (interface{}, bool)
+    Delete(key string) error
+    Flush() error
+    GetWithTTL(key string) (interface{}, time.Duration, bool)
+}
+
+type InMemoryCacheService struct {
+    cache *cache.Cache
+    defaultTTL time.Duration
+    cleanupInterval time.Duration
+}
+```
+
+**Use Cases:**
+- JWT token validation results
+- User session data
+- Frequently accessed greet messages
+- API response caching for idempotent endpoints
+
+### Phase 2: Redis-Compatible Shared Cache
+
+**Library Selection**: We will use **`github.com/redis/go-redis/v9`** with a **Redis-compatible open-source alternative**:
+
+**Primary Choice**: **Dragonfly** (https://www.dragonflydb.io/)
+- Redis-compatible
+- Open-source (Apache 2.0 license)
+- Written in C++ with multi-threaded architecture
+- 25x higher throughput than Redis
+- Lower latency
+- Drop-in Redis replacement
+
+**Fallback Choice**: **KeyDB** (https://keydb.dev/)
+- Multi-threaded Redis fork
+- Open-source (GPL license)
+- Better performance than Redis
+- Full Redis API compatibility
+
+**Implementation Plan:**
+```go
+type RedisCacheService struct {
+    client *redis.Client
+    defaultTTL time.Duration
+    prefix string
+}
+
+func NewRedisCacheService(config *config.CacheConfig) (*RedisCacheService, error) {
+    client := redis.NewClient(&redis.Options{
+        Addr:     config.Host + ":" + strconv.Itoa(config.Port),
+        Password: config.Password,
+        DB:       config.Database,
+        PoolSize: config.PoolSize,
+    })
+    
+    // Test connection
+    _, err := client.Ping(context.Background()).Result()
+    if err != nil {
+        return nil, fmt.Errorf("failed to connect to Redis: %w", err)
+    }
+    
+    return &RedisCacheService{
+        client: client,
+        defaultTTL: config.DefaultTTL,
+        prefix: config.Prefix,
+    }, nil
+}
+```
+
+**Configuration:**
+```yaml
+cache:
+  # In-memory cache configuration
+  in_memory:
+    enabled: true
+    default_ttl: 5m
+    cleanup_interval: 10m
+    max_items: 10000
+  
+  # Redis-compatible cache configuration
+  redis:
+    enabled: false
+    host: "localhost"
+    port: 6379
+    password: ""
+    database: 0
+    pool_size: 10
+    default_ttl: 5m
+    prefix: "dlc:"
+    use_dragonfly: true  # Set to false to use KeyDB
+```
+
+### Phase 3: Rate Limiting Implementation
+
+**Library Selection**: We will use **`github.com/ulule/limiter/v3`** because:
+
+✅ **Pros:**
+- Multiple storage backends (in-memory, Redis, etc.)
+- Sliding window algorithm
+- Distributed rate limiting support
+- Configurable rate limits
+- Middleware support for Chi router
+- Good performance
+
+**Implementation Plan:**
+```go
+// Rate limit configuration
+type RateLimitConfig struct {
+    Enabled          bool          `mapstructure:"enabled"`
+    RequestsPerHour  int           `mapstructure:"requests_per_hour"`
+    BurstLimit        int           `mapstructure:"burst_limit"`
+    IPWhitelist       []string      `mapstructure:"ip_whitelist"`
+    EndpointSpecific  map[string]struct {
+        RequestsPerHour int `mapstructure:"requests_per_hour"`
+        BurstLimit      int `mapstructure:"burst_limit"`
+    } `mapstructure:"endpoint_specific"`
+}
+
+// Rate limiter service
+type RateLimiterService struct {
+    limiter *limiter.Limiter
+    store   limiter.Store
+    config  *RateLimitConfig
+}
+
+func NewRateLimiterService(config *RateLimitConfig) (*RateLimiterService, error) {
+    var store limiter.Store
+    
+    // Use Redis if available, otherwise use in-memory
+    if config.UseRedis {
+        // Initialize Redis store
+        store, err = limiter.NewStoreRedisWithOptions(&limiter.StoreOptions{
+            Prefix: config.RedisPrefix,
+            // ... other Redis options
+        })
+    } else {
+        // Use in-memory store
+        store = limiter.NewStoreMemory()
+    }
+    
+    if err != nil {
+        return nil, fmt.Errorf("failed to create rate limiter store: %w", err)
+    }
+    
+    // Create rate limiter
+    rate := limiter.Rate{
+        Period: time.Hour,
+        Limit:  int64(config.RequestsPerHour),
+    }
+    
+    return &RateLimiterService{
+        limiter: limiter.New(store, rate),
+        store:   store,
+        config:  config,
+    }, nil
+}
+```
+
+**Chi Middleware:**
+```go
+func RateLimitMiddleware(limiter *RateLimiterService) func(http.Handler) http.Handler {
+    return func(next http.Handler) http.Handler {
+        return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
+            // Skip rate limiting for whitelisted IPs
+            clientIP := r.Header.Get("X-Real-IP")
+            if clientIP == "" {
+                clientIP = r.RemoteAddr
+            }
+            
+            for _, allowedIP := range limiter.config.IPWhitelist {
+                if clientIP == allowedIP {
+                    next.ServeHTTP(w, r)
+                    return
+                }
+            }
+            
+            // Get rate limit context
+            context, err := limiter.limiter.Get(r.Context(), clientIP)
+            if err != nil {
+                log.Error().Err(err).Str("ip", clientIP).Msg("Rate limit error")
+                http.Error(w, "Internal server error", http.StatusInternalServerError)
+                return
+            }
+            
+            // Check if rate limit is exceeded
+            if context.Reached > 0 {
+                w.Header().Set("X-RateLimit-Limit", strconv.Itoa(limiter.config.RequestsPerHour))
+                w.Header().Set("X-RateLimit-Remaining", "0")
+                w.Header().Set("X-RateLimit-Reset", strconv.Itoa(int(context.Reset)))
+                
+                http.Error(w, "Too many requests", http.StatusTooManyRequests)
+                return
+            }
+            
+            // Set rate limit headers
+            w.Header().Set("X-RateLimit-Limit", strconv.Itoa(limiter.config.RequestsPerHour))
+            w.Header().Set("X-RateLimit-Remaining", strconv.Itoa(limiter.config.RequestsPerHour-int(context.Reached)))
+            w.Header().Set("X-RateLimit-Reset", strconv.Itoa(int(context.Reset)))
+            
+            next.ServeHTTP(w, r)
+        })
+    }
+}
+```
+
+### Phase 4: Cache Invalidation Strategy
+
+**Approach**: Hybrid cache invalidation with multiple strategies:
+
+1. **Time-Based Expiration (TTL)**
+   - All cache entries have a TTL
+   - Automatic expiration prevents stale data
+   - Default TTL: 5 minutes for most data
+
+2. **Event-Based Invalidation**
+   - Cache keys are invalidated on specific events
+   - Example: User data cache invalidated on user update
+   - Uses pub/sub pattern for distributed invalidation
+
+3. **Versioned Cache Keys**
+   - Cache keys include data version
+   - When data changes, version increments
+   - Old cache entries naturally expire
+
+4. **Write-Through Caching**
+   - Data written to database and cache simultaneously
+   - Ensures cache is always up-to-date
+   - Used for critical data that must be consistent
+
+**Cache Key Strategy:**
+```go
+func GetCacheKey(prefix, entityType, entityID string) string {
+    return fmt.Sprintf("%s:%s:%s", prefix, entityType, entityID)
+}
+
+// Example: "dlc:user:123"
+// Example: "dlc:jwt:validation:token_hash"
+```

+      burst_limit: 10
+    "/api/v1/auth/register":
+      requests_per_hour: 50
+      burst_limit: 5
+```
+
+## Monitoring and Metrics
+
+**Cache Metrics:**
+- Cache hit/miss ratio
+- Average cache latency
+- Cache size and memory usage
+- Eviction rate
+- TTL distribution
+
+**Rate Limit Metrics:**
+- Requests allowed vs rejected
+- Rate limit exceeded events
+- Top limited IPs
+- Endpoint-specific rate limit usage
+
+**Prometheus Metrics:**
+```go
+var (
+    cacheHits = prometheus.NewCounterVec(prometheus.CounterOpts{
+        Name: "cache_hits_total",
+        Help: "Number of cache hits",
+    }, []string{"cache_type", "entity_type"})
+    
+    cacheMisses = prometheus.NewCounterVec(prometheus.CounterOpts{
+        Name: "cache_misses_total",
+        Help: "Number of cache misses",
+    }, []string{"cache_type", "entity_type"})
+    
+    rateLimitExceeded = prometheus.NewCounterVec(prometheus.CounterOpts{
+        Name: "rate_limit_exceeded_total",
+        Help: "Number of rate limit exceeded events",
+    }, []string{"endpoint", "ip"})
+)
+```
+
+## Security Considerations
+
+1. **Cache Security:**
+   - Never cache sensitive user data (passwords, tokens)
+   - Use separate cache prefixes for different data types
+   - Implement cache key hashing for sensitive data
+   - Set appropriate TTLs to limit exposure
+
+2. **Rate Limit Security:**
+   - Prevent rate limit bypass attacks
+   - Use X-Real-IP header for proper IP detection
+   - Implement rate limit for authentication endpoints
+   - Log rate limit violations for security monitoring
+
+3. **Redis Security:**
+   - Use authentication if enabled
+   - Implement TLS for Redis connections
+   - Use separate database numbers for different environments
+   - Limit Redis commands to prevent abuse
+
+## Performance Considerations
+
+1. **Cache Performance:**
+   - Benchmark cache operations
+   - Monitor cache latency
+   - Optimize cache key size
+   - Use appropriate data structures
+
+2. **Rate Limit Performance:**
+   - Use efficient rate limiting algorithm
+   - Minimize middleware overhead
+   - Cache rate limit decisions
+   - Batch rate limit checks where possible
+
+3. **Memory Management:**
+   - Set reasonable cache size limits
+   - Monitor memory usage
+   - Implement cache eviction policies
+   - Use memory-efficient data structures
+
+## Migration Strategy
+
+### From No Cache to In-Memory Cache
+1. Implement cache interface and in-memory service
+2. Add cache configuration with sensible defaults
+3. Gradually add caching to critical endpoints
+4. Monitor cache performance and hit ratios
+5. Adjust TTLs based on usage patterns
+
+### From In-Memory to Redis Cache
+1. Set up Dragonfly/KeyDB in development
+2. Implement Redis cache service
+3. Add fallback logic (Redis → in-memory)
+4. Test with both caches enabled
+5. Gradually migrate to Redis-only
+6. Monitor distributed cache performance
+
+### From No Rate Limiting to Rate Limiting
+1. Implement rate limiter with generous limits
+2. Add monitoring for rate limit events
+3. Gradually tighten limits based on usage
+4. Add IP whitelist for critical services
+5. Implement endpoint-specific limits
+6. Monitor and adjust as needed
+
+## Alternatives Considered
+
+### Cache Libraries
+1. **`github.com/bluele/gcache`** - More features but more complex
+2. **`github.com/allegro/bigcache`** - High performance but no TTL
+3. **`github.com/coocood/freecache`** - Very fast but limited API
+
+### Redis Alternatives
+1. **Redis Enterprise** - Commercial, not open-source
+2. **Memcached** - No persistence, simpler protocol
+3. **Couchbase** - More complex, document-oriented
+
+### Rate Limiting Libraries
+1. **`golang.org/x/time/rate`** - Simple but no distributed support
+2. **`github.com/juju/ratelimit`** - Good but limited features
+3. **Custom implementation** - Too much development effort
+
+## Success Metrics
+
+1. **Cache Effectiveness:**
+   - Cache hit ratio > 80%
+   - Average cache latency < 1ms
+   - Memory usage within limits
+
+2. **Rate Limiting Effectiveness:**
+   - < 1% of legitimate requests blocked
+   - Effective protection against abuse
+   - No impact on normal usage patterns
+
+3. **System Stability:**
+   - Reduced database load by 50%
+   - Consistent response times under load
+   - No cache-related outages
+
+## Risks and Mitigations
+
+| Risk | Mitigation |
+|------|------------|
+| Cache stampede | Implement cache warming and fallback logic |
+| Memory exhaustion | Set reasonable cache size limits and monitor usage |
+| Redis failure | Implement fallback to in-memory cache |
+| Rate limit false positives | Start with generous limits and monitor |
+| Performance degradation | Benchmark before and after implementation |
+| Cache inconsistency | Use appropriate invalidation strategies |
+
+## Future Enhancements
+
+1. **Cache Pre-warming** - Load frequently used data at startup
+2. **Two-Level Caching** - Local cache + distributed cache
+3. **Cache Compression** - For large cache objects
+4. **Dynamic Rate Limits** - Adjust based on system load
+5. **User-Specific Rate Limits** - Different limits for different user tiers
+6. **Cache Analytics** - Detailed usage patterns and optimization

+# Config Hot Reloading Strategy
+
+* Status: Proposed
+* Deciders: Gabriel Radureau, AI Agent
+* Date: 2026-04-05
+
+> **⚠️ Not yet implemented.** No `ConfigManager` exists in `pkg/config/` and Viper's `WatchConfig()` is not wired up. However, `features/config/config_hot_reloading.feature` has been written — BDD scenarios exist for a feature that is not yet built. Those tests are expected to fail until implementation begins.
+
+## Context and Problem Statement
+
+The dance-lessons-coach application currently loads configuration once at startup using Viper, which supports file-based configuration, environment variables, and defaults. However, the current implementation does not support runtime configuration changes without restarting the application.
+
+We need to determine whether and how to implement config hot reloading - the ability to detect changes to the optional `config.yaml` file and apply those changes without requiring a full application restart.
+
+## Decision Drivers
+
+* **Development convenience**: Hot reloading would allow developers to change configuration without restarting the server during development
+* **Production flexibility**: Ability to adjust certain configuration parameters without downtime
+* **Complexity**: Hot reloading adds significant complexity to the codebase
+* **Safety**: Some configuration changes require careful handling to avoid runtime errors
+* **Viper capabilities**: Viper already supports file watching through `viper.WatchConfig()`
+* **Configuration scope**: Not all configuration parameters can or should be hot-reloaded
+
+## Considered Options
+
+### Option 1: Full Hot Reloading with Viper WatchConfig
+
+Implement comprehensive hot reloading using Viper's built-in `WatchConfig()` functionality to monitor the config file and automatically reload when changes are detected.
+
+### Option 2: Selective Hot Reloading
+
+Only allow hot reloading for specific configuration sections that are safe to change at runtime (e.g., logging level, feature flags) while requiring restart for others (e.g., server host/port, database credentials).
+
+### Option 3: Manual Reload Endpoint
+
+Add an admin endpoint (e.g., `POST /api/admin/reload-config`) that triggers configuration reload when called, giving explicit control over when reloading happens.
+
+### Option 4: No Hot Reloading
+
+Maintain the current approach of loading configuration only at startup, requiring application restart for any configuration changes.
+
+## Decision Outcome
+
+Chosen option: **"Selective Hot Reloading"** because it provides the benefits of runtime configuration changes while maintaining safety and control. This approach:
+
+* Allows safe configuration changes without restart
+* Prevents dangerous runtime changes to critical parameters
+* Leverages Viper's existing capabilities
+* Provides a clear boundary between hot-reloadable and non-hot-reloadable settings
+
+## Implementation Strategy
+
+### Hot-Reloadable Configuration
+
+The following configuration parameters will support hot reloading:
+
+* **Logging level** (`logging.level`)
+* **Feature flags** (`api.v2_enabled`)
+* **Telemetry sampling** (`telemetry.sampler.type`, `telemetry.sampler.ratio`)
+* **JWT TTL** (`auth.jwt.ttl`)
+
+### Non-Hot-Reloadable Configuration
+
+These parameters will require application restart:
+
+* **Server settings** (`server.host`, `server.port`)
+* **Database credentials** (`database.*`)
+* **JWT secret** (`auth.jwt_secret`)
+* **Admin credentials** (`auth.admin_master_password`)
+
+### Implementation Plan
+
+```go
+// Add to config package
+type ConfigManager struct {
+    config     *Config
+    viper      *viper.Viper
+    changeChan chan struct{}
+    stopChan   chan struct{}
+}
+
+func NewConfigManager() (*ConfigManager, error) {
+    // Initialize Viper and load initial config
+    // Start file watcher if config file exists
+}
+
+func (cm *ConfigManager) StartWatching() {
+    if cm.viper != nil {
+        cm.viper.WatchConfig()
+        cm.viper.OnConfigChange(func(e fsnotify.Event) {
+            cm.handleConfigChange()
+        })
+    }
+}
+
+func (cm *ConfigManager) handleConfigChange() {
+    // Reload only safe configuration sections
+    // Update logging level if changed
+    // Update feature flags if changed
+    // Notify other components of changes
+    
+    log.Info().Msg("Configuration reloaded (partial)")
+}
+
+// Safe getter methods that work with hot reloading
+func (cm *ConfigManager) GetLogLevel() string {
+    // Return current value, potentially updated via hot reload
+}
+```
+
+### Configuration File Monitoring
+
+```go
+// In main application setup
+func main() {
+    configManager, err := config.NewConfigManager()
+    if err != nil {
+        log.Fatal().Err(err).Msg("Failed to initialize config")
+    }
+    
+    // Start watching for config changes
+    configManager.StartWatching()
+    
+    // Use configManager throughout application instead of direct config access
+}
+```
+
+## Pros and Cons of the Options
+
+### Option 1: Full Hot Reloading with Viper WatchConfig
+
+* **Good**: Maximum flexibility for configuration changes
+* **Good**: Leverages Viper's built-in capabilities
+* **Good**: Good for development workflow
+* **Bad**: High risk of runtime errors from unsafe changes
+* **Bad**: Complex to implement safely
+* **Bad**: Hard to debug configuration-related issues
+
+### Option 2: Selective Hot Reloading (Chosen)
+
+* **Good**: Safe approach with clear boundaries
+* **Good**: Balances flexibility and stability
+* **Good**: Easier to implement and maintain
+* **Good**: Clear documentation of what can be changed
+* **Bad**: More complex than no hot reloading
+* **Bad**: Requires careful design of config access patterns
+
+### Option 3: Manual Reload Endpoint
+
+* **Good**: Explicit control over when reloading happens
+* **Good**: Can be secured with authentication
+* **Good**: Good for production environments
+* **Bad**: Less convenient for development
+* **Bad**: Requires additional API endpoint management
+* **Bad**: Still needs same safety considerations as automatic reloading
+
+### Option 4: No Hot Reloading
+
+* **Good**: Simplest approach
+* **Good**: No risk of runtime configuration errors
+* **Good**: Easier to reason about application state
+* **Bad**: Requires restart for any configuration change
+* **Bad**: Less flexible for production adjustments
+* **Bad**: Slower development iteration
+
+## Configuration Change Handling
+
+### Safe Change Pattern
+
+```go
+// Example: Logging level change
+func (cm *ConfigManager) handleConfigChange() {
+    // Get new config values
+    newConfig := &Config{}
+    if err := cm.viper.Unmarshal(newConfig); err != nil {
+        log.Error().Err(err).Msg("Failed to unmarshal new config")
+        return
+    }
+    
+    // Apply safe changes
+    if newConfig.Logging.Level != cm.config.Logging.Level {
+        if err := cm.applyLogLevelChange(newConfig.Logging.Level); err != nil {
+            log.Error().Err(err).Msg("Failed to apply log level change")
+        }
+    }
+    
+    // Update other safe parameters...
+}
+
+func (cm *ConfigManager) applyLogLevelChange(newLevel string) error {
+    // Validate new level
+    level := parseLogLevel(newLevel)
+    
+    // Apply change
+    zerolog.SetGlobalLevel(level)
+    cm.config.Logging.Level = newLevel
+    
+    log.Info().Str("new_level", newLevel).Msg("Log level updated")
+    return nil
+}
+```
+
+### Error Handling
+
+* Invalid configuration changes are logged but don't crash the application
+* Failed changes revert to previous known-good values
+* Critical errors during reload trigger application shutdown
+* All changes are logged for audit purposes
+

+* [ADR-0006: Configuration Management](0006-configuration-management.md)
+
+## Configuration File Example with Hot-Reloadable Settings
+
+```yaml
+# config.yaml - These settings can be hot-reloaded
+server:
+  host: "0.0.0.0"
+  port: 8080
+
+logging:
+  level: "info"  # Can be changed without restart
+  json: false
+  output: ""
+
+api:
+  v2_enabled: false  # Can be changed without restart
+
+telemetry:
+  enabled: false
+  sampler:
+    type: "parentbased_always_on"  # Can be changed without restart
+    ratio: 1.0
+```
+
+## Migration Plan
+
+1. **Phase 1**: Implement ConfigManager wrapper around existing config
+2. **Phase 2**: Add selective hot reloading for logging level
+3. **Phase 3**: Extend to feature flags and telemetry settings
+4. **Phase 4**: Add documentation and examples
+5. **Phase 5**: Update all components to use ConfigManager instead of direct config access
+
+## Monitoring and Observability
+
+* Log all configuration changes with timestamps
+* Include previous and new values in change logs
+* Add metrics for configuration reload events
+* Provide admin endpoint to view current configuration
+
+## Security Considerations
+
+* Config file permissions should be restrictive
+* Hot reloading should be disabled in production by default
+* Configuration changes should be audited
+* Sensitive parameters should never be hot-reloadable
+
+## Future Enhancements
+
+* Configuration change webhooks
+* Configuration versioning and rollback
+* Configuration validation before applying changes
+* Multi-file configuration support

+# ADR 0024: BDD Test Organization and Isolation Strategy
+
+## Status
+**Accepted** ✅
+
+## Context
+
+As the dance-lessons-coach project grows, our BDD test suite has encountered several challenges. While we initially followed basic Godog patterns, we need to evolve our organization to handle complex scenarios like config hot reloading while maintaining test reliability.
+
+### Current Issues
+
+1. **Test Interdependence**: Tests affect each other through shared state (config files, database)
+2. **Timing Issues**: Config reloading and server restarts cause race conditions
+3. **Cognitive Load**: Large test files with many scenarios are hard to maintain
+4. **Flaky Tests**: Tests pass individually but fail when run together
+5. **Edge Case Handling**: Special setup/teardown requirements for certain tests
+
+### Godog Best Practices Alignment
+
+According to [Godog documentation](https://github.com/cucumber/godog) and community best practices, our current organization partially follows recommendations but needs improvement in:
+
+- **Feature Granularity**: Some files contain multiple unrelated features
+- **Step Organization**: Steps could be better grouped by domain
+- **Context Management**: Need better state isolation between scenarios
+- **Tagging Strategy**: Currently missing tag-based test selection
+
+## Decision
+
+Adopt a **modular, isolated test suite architecture** with the following principles:
+
+### 1. Test Organization by Feature (Godog-Aligned)
+
+Following [Godog best practices](https://github.com/cucumber/godog), we organize tests by business domain with proper feature granularity:
+
+```
+features/
+├── auth/                          # Business domain
+│   ├── authentication.feature     # Single feature per file
+│   ├── password_reset.feature     # Single feature per file
+│   └── user_management.feature    # Single feature per file
+├── config/                        # Business domain
+│   ├── hot_reloading.feature       # Single feature per file
+│   └── validation.feature          # Single feature per file
+├── greet/                         # Business domain
+│   ├── v1_greeting.feature         # Single feature per file
+│   └── v2_greeting.feature         # Single feature per file
+├── health/                        # Business domain
+│   └── health_check.feature        # Single feature per file
+└── jwt/                           # Business domain
+    ├── secret_rotation.feature     # Single feature per file
+    └── retention_policy.feature   # Single feature per file
+```
+
+**Key Improvements over current structure:**
+- ✅ **Single responsibility**: One feature per file
+- ✅ **Business alignment**: Grouped by domain, not technical concerns
+- ✅ **Scalability**: Easy to add new features without bloating files
+
+### 2. Isolation Strategies
+
+#### A. Config File Isolation
+- Each feature directory has its own config file pattern
+- Config files are cleaned up after each feature test run
+- Example: `features/auth/auth-test-config.yaml`
+
+#### B. Database Isolation
+- Use separate database schemas or suffixes per feature
+- Example: `dance_lessons_coach_auth_test`, `dance_lessons_coach_greet_test`
+
+#### C. Server Port Isolation
+- Assign different ports to different test groups
+- Prevents port conflicts during parallel testing
+
+### 3. Test Execution Strategy
+
+#### Option 1: Sequential Feature Testing (Recommended)
+```bash
+# Run tests by feature group
+./scripts/test-feature.sh auth
+./scripts/test-feature.sh config
+./scripts/test-feature.sh greet
+```
+
+#### Option 2: Parallel Feature Testing (Advanced)
+```bash
+# Run features in parallel with isolation
+./scripts/test-all-features-parallel.sh
+```
+
+### 4. Test Synchronization (Godog Best Practices)
+
+#### A. Explicit Waits with Timeouts
+Following Godog's [arrange-act-assert pattern](https://alicegg.tech/2019/03/09/gobdd.html):
+
+```go
+// Instead of fixed sleep times
+func waitForServerReady(maxAttempts int, delay time.Duration) error {
+    for i := 0; i < maxAttempts; i++ {
+        if serverIsReady() {
+            return nil
+        }
+        time.Sleep(delay)
+    }
+    return fmt.Errorf("server not ready after %d attempts", maxAttempts)
+}
+```
+
+#### B. Godog Context Management
+Implement proper context structs as recommended by Godog:
+
+```go
+// Feature-specific context for isolation
+type AuthContext struct {
+    client *testserver.Client
+    db     *sql.DB
+    users  map[string]UserData
+}
+
+func InitializeAuthContext() *AuthContext {
+    return &AuthContext{
+        client: testserver.NewClient(),
+        db:     connectToFeatureDB("auth"),
+        users:  make(map[string]UserData),
+    }
+}
+
+func CleanupAuthContext(ctx *AuthContext) {
+    // Cleanup resources
+    ctx.db.Close()
+}
+```
+
+#### C. Tag-Based Test Selection
+Add Godog tag support for selective test execution:
+
+```go
+// In feature files
+@smoke @auth
+Scenario: Successful user authentication
+  Given the server is running
+  When I authenticate with valid credentials
+  Then the authentication should be successful
+
+// Run specific tags
+go test ./features/... -tags=smoke
+godog --tags=@auth features/
+```
+
+#### B. Event-Based Synchronization
+```go
+// Use server lifecycle events
+func waitForConfigReload() error {
+    return waitForEvent("config_reloaded", 30*time.Second)
+}
+```
+
+#### C. Test Hooks with Timeouts
+```go
+// In test setup
+ctx.Step("^I wait for v2 API to be enabled$", func() error {
+    return waitForCondition(30*time.Second, func() bool {
+        return v2EndpointAvailable()
+    })
+})
+```
+
+### 5. Test Lifecycle Management
+
+#### Before Suite (Feature Level)
+```go
+func InitializeFeatureSuite(featureName string) {
+    // Setup feature-specific resources
+    initDatabaseForFeature(featureName)
+    createFeatureConfigFile(featureName)
+    startIsolatedServer(featureName)
+}
+```
+
+#### After Suite (Feature Level)
+```go
+func CleanupFeatureSuite(featureName string) {
+    // Cleanup feature-specific resources
+    cleanupDatabaseForFeature(featureName)
+    removeFeatureConfigFile(featureName)
+    stopIsolatedServer(featureName)
+}
+```
+
+### 6. Shell Script Integration
+
+Create feature-specific test scripts:
+
+```bash
+# scripts/test-feature.sh
+#!/bin/bash
+
+FEATURE=$1
+DATABASE="dance_lessons_coach_${FEATURE}_test"
+CONFIG="features/${FEATURE}/${FEATURE}-test-config.yaml"
+
+# Setup
+setup_feature_environment() {
+    echo "🧪 Setting up ${FEATURE} feature tests..."
+    create_database ${DATABASE}
+    generate_config ${CONFIG}
+}
+
+# Run tests
+run_feature_tests() {
+    echo "🚀 Running ${FEATURE} feature tests..."
+    DLC_DATABASE_NAME=${DATABASE} \
+    DLC_CONFIG_FILE=${CONFIG} \
+    go test ./features/${FEATURE}/... -v
+}
+
+# Teardown
+cleanup_feature_environment() {
+    echo "🧹 Cleaning up ${FEATURE} feature tests..."
+    drop_database ${DATABASE}
+    remove_config ${CONFIG}
+}
+
+# Main execution
+setup_feature_environment
+run_feature_tests
+cleanup_feature_environment
+```
+
+### 7. Configuration Management
+
+#### Feature-Specific Config Files
+```yaml
+# features/auth/auth-test-config.yaml
+server:
+  host: "127.0.0.1"
+  port: 9192  # Feature-specific port
+
+database:
+  name: "dance_lessons_coach_auth_test"  # Feature-specific database
+
+api:
+  v2_enabled: true  # Feature-specific settings
+
+auth:
+  jwt:
+    ttl: 1h
+```
+
+### 8. Test Data Management
+
+#### A. Feature-Scoped Data
+- Each feature gets its own data namespace
+- Example: `auth_user_*`, `greet_message_*` prefixes
+
+#### B. Automatic Cleanup
+```go
+func CleanupFeatureData(featureName string) {
+    // Remove all data created by this feature
+    db.Exec(fmt.Sprintf("DELETE FROM %s_* WHERE feature = '%s'", featureName, featureName))
+}
+```
+
+## Consequences
+
+### Positive
+
+1. **Improved Test Reliability**: Tests don't interfere with each other
+2. **Better Maintainability**: Smaller, focused test files
+3. **Faster Development**: Run only relevant tests during feature development
+4. **Easier Debugging**: Isolate issues to specific features
+5. **Parallel Testing**: Enable safe parallel execution
+6. **SOLID Compliance**: Single responsibility for test files
+
+### Negative
+
+1. **Increased Complexity**: More moving parts in test infrastructure
+2. **Resource Usage**: Multiple databases/servers consume more resources
+3. **Setup Time**: Initial test runs may be slower due to setup
+4. **Learning Curve**: Team needs to understand the isolation patterns
+
+### Neutral
+
+1. **Test Execution Time**: May increase or decrease depending on parallelization
+2. **CI/CD Changes**: Pipeline needs adaptation for new test organization
+
+## Implementation Plan
+
+### Phase 1: Refactor Current Tests (1-2 weeks)
+1. Split monolithic feature files into feature directories
+2. Create feature-specific test scripts
+3. Implement basic isolation (config files, database names)
+
+### Phase 2: Enhance Test Infrastructure (2-3 weeks)
+1. Add synchronization helpers to test framework
+2. Implement server lifecycle management
+3. Create comprehensive cleanup routines
+
+### Phase 3: Parallel Testing (Optional)
+1. Add parallel test execution capability
+2. Implement port management for parallel runs
+3. Add resource monitoring
+
+## Alternatives Considered
+
+### 1. Single Test Suite with Better Cleanup
+**Rejected because**: Doesn't solve fundamental interdependence issues
+
+### 2. Docker-Based Isolation
+**Rejected because**: Too heavyweight for local development
+
+### 3. Test Virtualization
+**Rejected because**: Overkill for current project size
+
+## Success Metrics
+
+1. **Test Reliability**: >95% pass rate in CI/CD
+2. **Test Isolation**: Ability to run any single feature test independently
+3. **Developer Experience**: Feature tests run in <30 seconds locally
+4. **Maintainability**: New team members can understand test structure in <1 hour

+# ADR 0025: BDD Scenario Isolation Strategies
+
+## Status
+**Accepted (Partial)** 🟡
+
+Phase 1 (schema-per-scenario DB isolation + `ScenarioState` manager in `pkg/bdd/steps/scenario_state.go`) is implemented.
+Phase 2 (cache key prefix strategy, in-memory store `Reset()` methods) is pending — blocked on ADR-0022 (rate limiting/cache) not yet implemented.
+
+## Context
+
+As our BDD test suite grows, we're encountering **test pollution** issues where scenarios interfere with each other through shared state. This is particularly problematic for:
+
+1. **Database state**: Scenarios create users, JWT secrets, config entries that persist across scenarios
+2. **JWT secret rotation**: Multiple secrets accumulate, affecting subsequent scenario authentication
+3. **Config file modifications**: Feature flag changes persist between tests
+4. **Gherkin Background steps**: Data set up in Background is visible to all scenarios in the feature
+
+Our current approach clears database tables after each scenario, but this has **race condition vulnerabilities** with concurrent scenario execution.
+
+### Gherkin Background Consideration
+
+Crucially, Gherkin's `Background` section runs **before each scenario** in a feature, not once before all scenarios. This means:
+
+```gherkin
+Feature: User registration
+  Background:
+    Given the database is empty
+    And a default admin user exists
+  
+  Scenario: Register new user
+    When I register user "alice"
+    Then user "alice" should exist
+  
+  Scenario: Register duplicate user
+    When I register user "alice"
+    Then I should see error "user already exists"
+```
+
+The second scenario fails because Background creates data that persists, and the first scenario's data isn't cleaned up. Background steps are re-executed before each scenario.
+
+## Decision Drivers
+
+* **Isolation**: Each scenario must start with a clean slate
+* **Performance**: Cleanup must be fast enough for CI/CD pipelines
+* **Concurrency**: Must work with parallel scenario execution
+* **Compatibility**: Must work with Gherkin Background steps
+* **Maintainability**: Solution should be simple to understand and debug
+
+## Considered Options
+
+### Option 1: Transaction Rollback (Rejected ❌)
+
+Wrap each scenario in a database transaction, rollback at the end.
+
+```go
+BeforeScenario: BEGIN;
+AfterScenario: ROLLBACK;
+```
+
+**Pros:**
+- Simple implementation
+- Fast - transaction rollback is nearly instant
+- No data cleanup needed
+
+**Cons:**
+- ❌ **Fails if scenario commits**: Nested transaction problem - `COMMIT` inside scenario releases the transaction, parent `ROLLBACK` has no effect
+- Cannot handle non-database state (JWT secrets in memory, config files)
+- Doesn't solve JWT secret pollution
+
+**Verdict: Not viable** - Too many scenarios use database transactions internally.
+
+---
+
+### Option 2: Clear Tables in Public Schema (Current ✅/⚠️)
+
+Delete all rows from all tables after each scenario.
+
+```go
+AfterScenario: DELETE FROM table1; DELETE FROM table2; ...
+```
+
+**Pros:**
+- Currently implemented
+- Works with any scenario code
+- Handles database state
+
+**Cons:**
+- ⚠️ **Race conditions**: Concurrent scenarios can interleave - Scenario A deletes data while Scenario B is still using it
+- ⚠️ **Slow**: Must delete from all tables, reset sequences
+- ❌ **Misses in-memory state**: JWT secrets, config changes persist
+- ❌ **Doesn't handle Background**: Background data is shared across scenarios
+
+**Verdict: Partially adequate** - Works for sequential execution but has parallel execution issues.
+
+---
+
+### Option 3: Schema-per-Scenario (Recommended ✅)
+
+Create a unique PostgreSQL schema for each scenario, drop it after.
+
+```go
+BeforeScenario:
+  schema := "test_" + sha256(scenario.Name)[:8]
+  CREATE SCHEMA schema;
+  SET search_path = schema, public;
+  
+AfterScenario:
+  DROP SCHEMA schema CASCADE;
+```
+
+**Pros:**
+- ✅ **True isolation**: Each scenario has its own database namespace
+- ✅ **Works with transactions**: Scenario can commit freely - entire schema is dropped
+- ✅ **Works with Background**: Background runs in scenario's schema, data is isolated
+- ✅ **Fast**: Schema drop is instant (just metadata deletion)
+- ✅ **Handles concurrent scenarios**: Different schemas = no conflicts
+
+**Cons:**
+- Requires `CREATE/DROP SCHEMA` database privileges in test environment
+- Some ORMs may hardcode `public` schema - need to use `SET search_path` carefully
+- Test DB must allow many schemas (typically fine for PostgreSQL)
+- We need to handle `search_path` in connection pooling (each scenario needs its own connection)
+
+**Implementation notes:**
+- Use `Luego` (PostgreSQL schema prefix) approach: `test_{hash}`
+- Hash: `sha256(feature_name + scenario_name)[:8]` for consistency across runs
+- Execute Background steps in the scenario's schema context
+- Set `search_path` at the connection level, not globally
+
+---
+
+### Option 4: Database-per-Feature ⚠️
+
+Create a separate database for each feature file.
+
+```go
+BeforeFeature: CREATE DATABASE feature_auth;
+AfterFeature: DROP DATABASE feature_auth;
+```
+
+**Pros:**
+- Strong isolation between features
+- Simple implementation
+
+**Cons:**
+- ❌ **Doesn't isolate scenarios within a feature** - Background data shared across scenarios
+- Database creation is slower than schema creation
+- Harder to manage in CI (more databases to create/cleanup)
+- Still need table clearing between scenarios within a feature
+
+**Verdict: Insufficient** - Doesn't solve intra-feature pollution.
+
+---
+
+### Option 5: Schema-per-Feature + Table Clearing per Scenario ⚠️
+
+Create one schema per feature, clear tables between scenarios.
+
+```go
+BeforeFeature: CREATE SCHEMA feature_auth;
+AfterFeature: DROP SCHEMA feature_auth;
+AfterScenario: DELETE FROM all_tables;
+```
+
+**Pros:**
+- Isolates features from each other
+- Simpler than per-scenario schemas
+
+**Cons:**
+- ❌ **Scenarios within a feature share state** - Background data persists
+- Still has race conditions with concurrent scenarios in same feature
+- Requires table clearing overhead
+
+**Verdict: Better than current but still has issues**.
+
+---
+
+## Decision Outcome
+
+**Chosen option: Schema-per-Scenario + In-Memory State Reset + Per-Scenario Step State (Option 3 Enhanced)**
+
+We will implement schema-per-scenario because it:
+
+1. Provides **true isolation** for all database state
+2. **Works with Gherkin Background** - Background runs in each scenario's schema
+3. **Handles concurrent execution** - No race conditions
+4. **Works with scenario transactions** - Scenarios can commit freely
+5. Is **fast** - Schema operations are cheap
+
+**However, we discovered a critical limitation:** PostgreSQL schemas only isolate **database tables**. In-memory state (application-level caches, user stores, JWT secret managers) **persists across scenarios** because they're stored in the shared `sharedServer` Go instance. Schema isolation does NOT solve this.
+
+### Enhanced Strategy: Multi-Layer Isolation
+
+To achieve **complete scenario isolation**, we need a **3-layer approach:**
+
+| Layer | Component | Strategy | Status |
+|-------|-----------|----------|--------|
+| DB | PostgreSQL tables | Schema-per-scenario | ✅ Implemented |
+| Memory | Server-level state (JWT secrets) | Reset to initial state | ✅ Implemented |
+| Memory | Step-level state (tokens, user IDs) | Per-scenario state map | ✅ Implemented |
+| Memory | User store | Reset/clear between scenarios | ⚠️ TODO |
+| Memory | Auth cache | Reset/clear between scenarios | ⚠️ TODO |
+| Cache | Redis/Memcached | Key prefix with schema hash | ⚠️ TODO |
+
+### Layer 3: Per-Scenario Step State Isolation
+
+**New insight from test failures:** Step definition structs (AuthSteps, GreetSteps, etc.) maintain state in their fields:
+- `lastToken`, `firstToken` in AuthSteps
+- `lastUserID` in AuthSteps
+
+This state **spills across scenarios** even with schema isolation, because struct fields are shared across all scenarios in a test process.
+
+**Solution:** Create a `ScenarioState` manager with per-scenario isolation:
+
+```go
+type ScenarioState struct {
+    LastToken  string
+    FirstToken string
+    LastUserID uint
+}
+
+type scenarioStateManager struct {
+    mu      sync.RWMutex
+    states  map[string]*ScenarioState  // keyed by scenario hash
+}
+
+// Usage in step definitions:
+func (s *AuthSteps) iShouldReceiveAValidJWTToken() error {
+    state := steps.GetScenarioState(s.scenarioName)
+    state.LastToken = extractedToken
+    // ...
+}
+```
+
+**Benefits:**
+- ✅ Zero code changes to step definitions (with helper functions)
+- ✅ Thread-safe (sync.RWMutex)
+- ✅ Consistent state per scenario
+- ✅ Automatic cleanup via BeforeScenario/AfterScenario hooks
+- ✅ Works with random test order
+
+**Status:** Implemented in `pkg/bdd/steps/scenario_state.go`
+
+### Key Insight: Cache and In-Memory Store Isolation
+
+**For caches (Redis, Memcached, in-process):**
+- Use **schema hash as key prefix/suffix**: `cache_key_{schema_hash}` or `{schema_hash}_cache_key`
+- This ensures each scenario gets isolated cache namespace
+- Works even with external cache services
+- Consistent with schema isolation philosophy
+
+**For in-memory stores (user repository, etc.):**
+- Add `Reset()` methods that clear all state
+- Call in `AfterScenario` alongside schema teardown
+- Or use schema-prefix approach for shared stores
+
+### Alternative Approach: Background Explicit State Setup
+
+**Considered but rejected:** Adding explicit "Given no user X exists" steps or heavy Background sections.
+
+**Pros:** More readable, explicit about state
+**Cons:**
+- Error-prone (must remember for every entity)
+- Verbose (many Given steps)
+- Doesn't scale with many entities
+- Still has race conditions with concurrent scenarios
+
+**Verdict:** Automated cleanup (schema drop + memory reset) is more reliable than manual Background setup.
+
+### Implementation Plan
+
+**Phase 1: Foundation (✅ Complete)**
+- Add scenario-aware schema management to test server
+- Implement schema creation/drop in BeforeScenario/AfterScenario hooks
+- Handle `search_path` configuration for each scenario's database connection
+
+**Phase 2: In-Memory State Reset (🟡 TODO)**
+- Add `ResetUsers()` method to clear in-memory user store
+- Add `ResetCache()` method for auth/rateLimiting caches
+- Call these in AfterScenario alongside JWT secret reset
+- **Cache key strategy**: `key_{schema_hash}` for all cache operations
+
+**Phase 3: Connection Pooling**
+- Configure connection pool to respect per-scenario `search_path`
+- Each scenario gets isolated connections
+
+**Phase 4: Validation**
+- Run full test suite to verify complete isolation
+- Fix any hardcoded `public` schema references
+
+### Schema Naming Convention
+
+```
+Schema name: test_{sha256(feature:scenario)[:8]}
+Cache key prefix: {sha256(feature:scenario)[:8]}_
+```
+
+Example:
+- Feature: `auth`, Scenario: `Successful user authentication`
+- Hash: `sha256("auth:Successful user authentication")[:8]` = `a3f7b2c1`
+- Schema: `test_a3f7b2c1`
+- Cache key: `a3f7b2c1_user:newuser` instead of just `user:newuser`
+
+Benefits:
+- Unique per scenario
+- Consistent across test runs (same scenario = same hash)
+- Short (8 chars) - efficient for cache keys
+- Identifiable for debugging
+
+### Schema Naming Convention
+
+```
+Schema name: test_{sha256(feature + scenario)[:8]}
+```
+
+Example:
+- Feature: `auth`, Scenario: `Successful user authentication`
+- Hash: `sha256("auth_Successful user authentication")[:8]` = `a3f7b2c1`
+- Schema: `test_a3f7b2c1`
+
+Benefits:
+- Unique per scenario
+- Consistent across test runs (same scenario = same schema)
+- Short (8 chars + prefix = 14 chars max)
+- Identifiable for debugging
+

+# BDD Implementation Plan - Iterative Approach
+
+Based on ADR 0024: BDD Test Organization and Isolation Strategy
+
+## Phase 1: Refactor Current Tests (1-2 weeks)
+
+### Objective: Split monolithic feature files into modular, isolated components
+
+### Tasks:
+1. **Split feature files by business domain**
+   - Create `features/auth/` directory
+   - Create `features/config/` directory  
+   - Create `features/greet/` directory
+   - Create `features/health/` directory
+   - Create `features/jwt/` directory
+
+2. **Implement feature-specific isolation**
+   - Add config file patterns: `features/{domain}/{domain}-test-config.yaml`
+   - Implement database naming: `dance_lessons_coach_{domain}_test`
+   - Assign unique ports per feature group
+
+3. **Create feature-specific test scripts**
+   - Implement `scripts/test-feature.sh` with feature parameter

+# API Endpoints
+
+REST API reference for `dance-lessons-coach`. Extracted from the original `AGENTS.md` (Tâche 6 restructure) for lazy-loading compatibility with Mistral Vibe.
+
+## Base URL
+
+```
+http://localhost:8080
+```
+
+## OpenAPI Documentation
+
+- **Swagger UI:** `http://localhost:8080/swagger/`
+- **OpenAPI Spec:** `http://localhost:8080/swagger/doc.json`
+
+The API provides interactive documentation using Swagger UI with complete OpenAPI 2.0 specification. All endpoints, request/response models, and validation rules are documented using a **hierarchical tagging system**.
+
+**Features:**
+
+- Interactive API exploration with hierarchical organization
+- Try-it-out functionality for all endpoints
+- Model schemas with examples
+- Response examples with validation rules
+- Hierarchical tag structure for better navigation
+
+**Generation:** Documentation is auto-generated from code annotations using [swaggo/swag](https://github.com/swaggo/swag) with the command:
+
+```bash
+go generate ./pkg/server/
+```
+
+**Tag Organization:**
+
+- `API/v1/Greeting` — Version 1 greeting endpoints
+- `API/v2/Greeting` — Version 2 greeting endpoints
+- `System/Health` — Health and readiness endpoints
+
+**Hierarchical Benefits:**
+
+- Clear separation between API domains (API vs System)
+- Version organization within each domain
+- Natural hierarchy in Swagger UI
+- Scalable for future API growth
+
+**Embedded Documentation:** The OpenAPI spec is embedded in the binary using Go's `//go:embed` directive for single-binary deployment.
+
+---
+
+## Health Check
+
+```http
+GET /api/health
+```
+
+**Response:**
+
+```json
+{"status":"healthy"}
+```
+
+## Version Info
+
+```http
+GET /api/version
+GET /api/version?format=plain
+GET /api/version?format=full
+GET /api/version?format=json
+```
+
+Returns the running binary version (injected at build time via `-ldflags`). The `format` query parameter controls the response shape:
+
+- `format=plain` (or `?format=short`): plain text version (e.g. `1.0.0`)
+- `format=full`: detailed multi-line text (Version, Commit, Built date, Go version)
+- `format=json` (default): structured JSON `{"version": "1.0.0", "commit": "abc1234", "built": "...", "go_version": "go1.26.1"}`
+
+## Readiness Check
+
+```http
+GET /api/ready
+```
+
+**Responses:**
+
+- Normal operation: `{"ready":true}` (HTTP 200)
+- During shutdown: `{"ready":false}` (HTTP 503 Service Unavailable)
+
+**Purpose:** Indicates whether the server is ready to accept new requests. Returns false during graceful shutdown to allow existing requests to complete while preventing new ones.

+# CLI Management Guide
+
+Complete reference for the `dance-lessons-coach` CLI, server lifecycle, and configuration. Extracted from the original `AGENTS.md` (Tâche 6 restructure) for lazy-loading compatibility with Mistral Vibe.
+
+## Cobra CLI (Recommended)
+
+`dance-lessons-coach` includes a modern CLI built with Cobra:
+
+```bash
+# Show help and available commands
+./bin/dance-lessons-coach --help
+
+# Show version information
+./bin/dance-lessons-coach version
+
+# Greet someone by name
+./bin/dance-lessons-coach greet John
+
+# Start the server
+./bin/dance-lessons-coach server
+```
+
+**Available Commands:**
+
+- `version` — Print version information
+- `server` — Start the dance-lessons-coach server
+- `greet [name]` — Greet someone by name
+- `help` — Built-in help system
+- `completion` — Generate shell completion scripts
+
+**Server Command Flags:**
+
+- `--config` — Config file path
+- `--env` — Environment (`dev`, `staging`, `prod`)
+- `--debug` — Enable debug logging
+
+## Version Information
+
+The server provides runtime version information:
+
+```bash
+# Check version using new CLI
+./bin/dance-lessons-coach version
+
+# Check version using server binary
+./bin/server --version
+
+# Output:
+dance-lessons-coach Version Information:
+  Version:   1.0.0
+  Commit:    abc1234
+  Built:     2026-04-05T10:00:00+0000
+  Go:        go1.26.1
+```
+
+For full version management workflow (bump, release, build with version), see [`version-management-guide.md`](version-management-guide.md).
+
+## Server Control Script
+
+A shell script manages the server lifecycle:
+
+```bash
+cd /Users/gabrielradureau/Work/Vibe/DanceLessonsCoach
+
+./scripts/start-server.sh start     # Start the server
+./scripts/start-server.sh status    # Check server status
+./scripts/start-server.sh test      # Test API endpoints
+./scripts/start-server.sh logs      # View server logs
+./scripts/start-server.sh stop      # Stop the server
+./scripts/start-server.sh restart   # Restart
+```
+
+**Available subcommands:**
+
+- `start` — Start the server in background with proper logging
+- `stop` — Stop the server gracefully
+- `restart` — Restart the server
+- `status` — Check if server is running
+- `logs` — Show recent server logs
+- `test` — Test all API endpoints
+
+## Manual Server Management
+
+For direct control:
+
+```bash
+cd /Users/gabrielradureau/Work/Vibe/DanceLessonsCoach
+./scripts/start-server.sh start
+```
+
+**Expected output:**
+
+```
+Server running on :8080
+[INF] Starting HTTP server on :8080
+[TRC] Registering greet routes
+[TRC] Greet routes registered
+```
+
+**Features:**
+
+- Context-aware server initialization
+- Graceful shutdown handling
+- Signal-based termination (`SIGINT`, `SIGTERM`)
+- 30-second shutdown timeout
+- Proper resource cleanup
+
+## Configuration
+
+Configuration via environment variables with `DLC_` prefix:
+
+| Option | Environment Variable | Default | Description |
+|---|---|---|---|
+| Host | `DLC_SERVER_HOST` | `0.0.0.0` | Server bind address |
+| Port | `DLC_SERVER_PORT` | `8080` | Server listening port |
+| Shutdown Timeout | `DLC_SHUTDOWN_TIMEOUT` | `30s` | Graceful shutdown timeout |
+| JSON Logging | `DLC_LOGGING_JSON` | `false` | Enable JSON format logging |
+| Log Output | `DLC_LOGGING_OUTPUT` | `""` | Log output file path (empty for stderr) |
+
+**Examples:**
+
+```bash
+# Custom port
+export DLC_SERVER_PORT=9090
+./scripts/start-server.sh start
+
+# Custom host and port
+export DLC_SERVER_HOST="127.0.0.1"
+export DLC_SERVER_PORT=8081
+./scripts/start-server.sh start
+
+# Custom shutdown timeout
+export DLC_SHUTDOWN_TIMEOUT=45s
+
+# Enable JSON logging
+export DLC_LOGGING_JSON=true
+
+# Log to file
+export DLC_LOGGING_OUTPUT="server.log"
+
+# Combined: JSON logging to file
+export DLC_LOGGING_JSON=true
+export DLC_LOGGING_OUTPUT="server.json.log"
+```
+
+**Configuration File Support:**
+
+A `config.example.yaml` file is provided as a template. By default, the application looks for `config.yaml` in the current working directory.
+
+To specify a custom config file path, set the `DLC_CONFIG_FILE` environment variable:
+
+```bash
+DLC_CONFIG_FILE="/path/to/config.yaml" go run ./cmd/server
+```
+
+Example `config.yaml`:
+
+```yaml
+server:
+  host: "0.0.0.0"
+  port: 8080
+
+shutdown:
+  timeout: 30s
+
+logging:
+  json: false
+```
+
+**Configuration Loading Precedence:**
+
+1. **File-based configuration** (highest precedence)
+2. **Environment variables** (override defaults, overridden by config file)
+3. **Default values** (fallback)
+
+All configuration is validated on startup. Invalid configurations cause server startup failure. Configuration values and source are logged at startup.
+
+**Verification:**
+
+```bash
+DLC_SERVER_PORT=9090 DLC_SERVER_HOST="127.0.0.1" ./scripts/start-server.sh start
+
+curl http://127.0.0.1:9090/api/health
+# Expected: {"status":"healthy"}
+```
+
+## Server Status
+
+```bash
+# Check health endpoint
+curl -s http://localhost:8080/api/health
+
+# Check readiness endpoint
+curl -s http://localhost:8080/api/ready
+```
+
+**Expected responses:**
+
+- Health: `{"status":"healthy"}`
+- Readiness (normal): `{"ready":true}`
+- Readiness (during shutdown): `{"ready":false}` (HTTP 503)
+
+**Endpoint Differences:**
+
+- **Health endpoint** (`/api/health`): Indicates if the application is running and functional
+- **Readiness endpoint** (`/api/ready`): Indicates if the application is ready to accept traffic
+
+**Use Cases:**
+
+- **Health**: Used by load balancers to check if the app is alive
+- **Readiness**: Used by Kubernetes / service meshes to determine if the app can accept new requests
+
+**During Graceful Shutdown:**
+
+- Health endpoint continues to return `{"status":"healthy"}`
+- Readiness endpoint returns `{"ready":false}` with HTTP 503 Service Unavailable
+- This allows existing requests to complete while preventing new requests
+
+## Stopping the Server
+
+To stop the server gracefully:
+
+```bash
+# Send SIGTERM for graceful shutdown
+kill -TERM $(lsof -ti :8080)
+
+# Or send SIGINT (Ctrl+C equivalent)
+pkill -INT -f "go run"
+```
+
+**Graceful shutdown process:**
+
+1. Server receives termination signal
+2. Logs shutdown message
+3. Stops accepting new connections
+4. Waits up to 30 seconds for active requests to complete
+5. Closes all connections cleanly
+6. Exits with proper cleanup
+
+For force stop (if graceful shutdown hangs):
+
+```bash
+kill -9 $(lsof -ti :8080)
+```
+
+**Verification:**
+
+```bash
+curl -s http://localhost:8080/api/health
+# Should return connection refused
+```

+
+## Adding a New API Endpoint
+
+```go
+// 1. Add to interface
+func (h *apiV1GreetHandler) RegisterRoutes(router chi.Router) {
+    router.Get("/", h.handleGreetQuery)
+    router.Get("/{name}", h.handleGreetPath)
+    router.Post("/custom", h.handleCustomGreet) // New endpoint
+}
+
+// 2. Implement handler
+func (h *apiV1GreetHandler) handleCustomGreet(w http.ResponseWriter, r *http.Request) {
+    // Parse request
+    // Call service
+    // Return JSON response
+}
+```
+
+## Logging with Zerolog
+
+```go
+// Trace level logging
+log.Trace().Ctx(ctx).Str("key", "value").Msg("message")
+
+// Info level
+log.Info().Msg("Important event")
+
+// Error level
+log.Error().Err(err).Msg("Error occurred")
+```
+
+For the full logging strategy (when to use Trace vs Info, performance considerations), see [ADR-0003 — Zerolog Logging](../adr/0003-zerolog-logging.md).
+
+## Using `context.Context`
+
+```go
+// Pass context through calls
+func handler(w http.ResponseWriter, r *http.Request) {
+    result := service.Greet(r.Context(), "John")
+    // ...
+}
+
+// Create context with values
+ctx := context.WithValue(r.Context(), "key", "value")
+
+// Create context with timeout
+ctx, cancel := context.WithTimeout(r.Context(), 5*time.Second)
+defer cancel()
+```
+
+For the rationale behind context-aware services, see [ADR-0004 — Interface-Based Design](../adr/0004-interface-based-design.md).

+# Troubleshooting
+
+Common issues and their resolution. Extracted from the original `AGENTS.md` and merged with relevant sections from `AGENT_USAGE_GUIDE.md` and `BDD_GUIDE.md`. Refer back to those guides for context-specific troubleshooting (agent workflows, BDD test failures).
+
+## Port Already in Use
+
+```bash
+# Find and kill process using port 8080
+kill -TERM $(lsof -ti :8080)
+
+# Force kill if graceful does not work
+kill -9 $(lsof -ti :8080)
+```
+
+## Server Not Responding
+
+```bash
+# Check if running
+curl -s http://localhost:8080/api/health
+
+# Restart server using control script
+./scripts/start-server.sh restart
+
+# View recent logs
+./scripts/start-server.sh logs
+```
+
+If health endpoint returns connection refused, the server may have crashed. Check logs in `./scripts/start-server.sh logs` for stack traces.
+
+## Dependency Issues
+
+```bash
+# Clean and rebuild
+go mod tidy
+go build ./...
+
+# If dependency version conflicts persist
+go mod download
+go mod verify
+```
+
+## Tests Failing
+
+### Unit tests
+
+```bash
+# Run with verbose output
+go test -v ./...
+
+# Check specific test
+go test ./pkg/greet/ -run TestName
+```
+
+### BDD tests
+
+See [`BDD_GUIDE.md`](BDD_GUIDE.md) for the full BDD troubleshooting workflow (Godog setup, scenario isolation, step matching). Common BDD issues:
+
+- **Step not found** → check `pkg/bdd/steps/` for the step definition file
+- **Scenario state leaking** → review [ADR-0025](../adr/0025-bdd-scenario-isolation-strategies.md) for the isolation pattern
+- **Database not reset** → ensure the test fixtures cleanup runs (BDD scenario After hooks)
+
+## Configuration Not Loading
+
+The application logs the configuration source at startup. Check logs for:
+
+```
+[INF] Configuration loaded from: file:config.yaml
+# or
+[INF] Configuration loaded from: env
+# or
+[INF] Configuration loaded from: defaults
+```
+
+If config is not loading as expected:
+
+1. Verify file exists and is readable: `ls -la config.yaml`
+2. Verify env vars are exported: `env | grep DLC_`
+3. Check for typos in keys (case-sensitive)
+4. Review [`AGENT_USAGE_GUIDE.md`](AGENT_USAGE_GUIDE.md) section "Configuration troubleshooting"
+
+## OpenTelemetry Not Tracing
+
+1. Verify Jaeger is running: `docker ps | grep jaeger`
+2. Check `DLC_TELEMETRY_ENABLED=true` in environment or `telemetry.enabled: true` in config
+3. Verify OTLP endpoint reachable: `nc -zv localhost 4317`
+4. Check sampler is not `always_off`
+5. See [`OBSERVABILITY.md`](OBSERVABILITY.md) for full setup
+
+## Build Failures
+
+```bash
+# Clear caches
+go clean -cache -modcache
+go mod download
+
+# Rebuild
+go build ./...
+```
+
+If errors persist, see [`local-ci-cd-testing.md`](local-ci-cd-testing.md) for the CI/CD pipeline that mirrors the production build.
+
+## Where to Look Next

+# BDD Test Tags Documentation
+
+This document describes the tagging system used in the dance-lessons-coach BDD tests for selective test execution.
+
+## Tag Categories
+
+### Feature Tags
+Used to categorize tests by feature area:
+- `@auth` - Authentication and user management tests
+- `@config` - Configuration and hot reloading tests  
+- `@greet` - Greeting service tests
+- `@health` - Health check and monitoring tests
+- `@jwt` - JWT secret rotation and retention tests
+
+### Priority Tags
+Used to categorize tests by importance:
+- `@smoke` - Basic smoke tests that verify core functionality
+- `@critical` - Critical path tests that must always pass
+- `@basic` - Basic functionality tests
+- `@advanced` - Advanced or edge case scenarios
+- `@nice_to_have` - Optional features that would be nice to have but aren't critical
+
+### Component Tags
+Used to categorize tests by system component:
+- `@api` - API endpoint tests
+- `@v2` - Version 2 API tests
+- `@database` - Database interaction tests
+- `@security` - Security-related tests
+
+### Exclusion Tags
+Used to exclude tests from execution:
+- `@flaky` - Tests that are unstable or intermittently fail
+- `@todo` - Tests with pending step implementations
+- `@skip` - Tests that should be skipped entirely
+
+### Nice-to-Have Tag
+
+The `@nice_to_have` tag is used to mark scenarios that test optional features or enhancements. These are features that would be beneficial to have but aren't critical for the core functionality of the system.
+
+**Usage:**
+- Add `@nice_to_have` to scenarios testing optional features
+- These scenarios are typically excluded from critical path testing
+- Useful for marking "stretch goal" functionality
+
+**Example:**
+```gherkin
+@nice_to_have @greet
+Scenario: Greeting with custom formatting options
+  Given the server is running
+  When I request a greeting with bold formatting
+  Then the response should contain HTML bold tags
+```
+
+### Work In Progress Tag
+Used to override exclusions for active development:
+- `@wip` - Work In Progress - overrides exclusion tags to allow focused development
+
+**Usage:** Add `@wip` to scenarios you're actively working on, even if they have other exclusion tags like `@todo` or `@skip`. The `@wip` tag takes precedence and allows the scenario to run.
+
+**Example:**
+```gherkin
+@todo @wip
+Scenario: JWT authentication with multiple secrets
+  Given the server is running with multiple JWT secrets
+  When I authenticate with valid credentials
+  Then I should receive a valid JWT token
+```
+
+### Command-Line Tag Override
+You can override the default tag filtering by setting the `GODOG_TAGS` environment variable when running tests.
+
+**Usage:**
+```bash
+# Run only @wip scenarios
+GODOG_TAGS="@wip" go test ./features/jwt/...
+
+# Run smoke tests only
+GODOG_TAGS="@smoke" go test ./features/...
+
+# Run specific combination
+GODOG_TAGS="@jwt && ~@todo" go test ./features/...
+
+# Combine with other environment variables
+DLC_DATABASE_HOST=localhost GODOG_TAGS="@wip" go test ./features/jwt/...
+```
+
+### Test Randomization Control
+You can control test execution order using the `GODOG_RANDOM_SEED` environment variable.
+
+**Usage:**
+```bash
+# Use random test order (default)
+GODOG_RANDOM_SEED="" go test ./features/
+
+# Use fixed seed for reproducible test runs
+GODOG_RANDOM_SEED=17925 go test ./features/
+
+# Combine with tag filtering
+GODOG_RANDOM_SEED=17925 GODOG_TAGS="@wip" go test ./features/
+
+# Debug specific test failures by reproducing exact execution order
+GODOG_RANDOM_SEED=17925 DLC_DATABASE_HOST=localhost go test ./features/jwt/
+```
+
+**Benefits:**
+- **Reproducibility**: Same seed produces same test order
+- **Debugging**: Easily reproduce failed test runs
+- **CI/CD**: Set fixed seeds for consistent test execution
+- **Backward compatible**: Defaults to random order when not specified
+
+**Example from test output:**
+```
+30 scenarios (11 passed, 19 failed)
+147 steps (104 passed, 19 failed, 24 skipped)
+4.474215346s
+Randomized with seed: 17925
+```
+
+To reproduce this exact test run:
+```bash
+GODOG_RANDOM_SEED=17925 go test ./features/
+```
+
+### Random Port Selection (Default Behavior)
+
+By default, BDD tests use **random ports** (10000-19999) to prevent port conflicts during parallel execution. This ensures tests can run reliably in CI/CD pipelines and when executed multiple times.
+
+**Benefits:**
+- ✅ No port conflicts in parallel test execution
+- ✅ Safe for repeated test runs
+- ✅ Better for CI/CD environments
+
+**Disable random ports (not recommended):**
+```bash
+FIXED_TEST_PORT=true go test ./features/...
+```
+
+**Force specific port (debugging only):**
+```bash
+# Create a test config file with fixed port
+echo "server:
+  port: 9191" > test-config.yaml
+FEATURE=debug FIXED_TEST_PORT=true go test ./features/...
+```
+
+### Test Validation Process
+
+To ensure test suite stability, follow this validation process:
+
+**Validation Command:**
+```bash
+# Clean cache and run all tests 20 times
+echo "🧪 Validating test suite stability..."
+for i in {1..20}; do
+    echo "Run $i/20..."
+    go clean -testcache
+    if ! go test ./... > /dev/null 2>&1; then
+        echo "❌ Test run $i failed"
+        go test ./... -v
+        exit 1
+    fi
+done
+echo "✅ All 20 test runs passed successfully!"
+```
+
+**Failure Handling:**
+- If any test fails during validation, mark it as `@wip` and investigate
+- Use `@flaky` tag for intermittently failing tests
+- Document the issue in the test scenario comments
+
+**Success Criteria:**
+- ✅ 100% pass rate across 20 consecutive runs
+- ✅ No undefined/pending steps
+- ✅ No race conditions or port conflicts
+- ✅ Consistent execution time
+
+**CI/CD Integration:**
+```yaml
+- name: Validate Test Suite
+  run: |
+    echo "🧪 Running 20 validation runs..."
+    for i in {1..20}; do
+      echo "Run $i/20"
+      go clean -testcache
+      go test ./... || exit 1
+    done
+    echo "✅ Test suite validated successfully"
+```
+
+### Stop On Failure Control
+You can control whether tests stop on first failure using the `GODOG_STOP_ON_FAILURE` environment variable.
+
+**Usage:**
+```bash
+# Stop on first failure (strict mode)
+GODOG_STOP_ON_FAILURE="true" go test ./features/jwt/...
+
+# Continue after failures (lenient mode)
+GODOG_STOP_ON_FAILURE="false" go test ./features/jwt/...
+
+# Combine with tag filtering
+GODOG_TAGS="@wip" GODOG_STOP_ON_FAILURE="true" go test ./features/jwt/...
+```
+
+**Default Behavior:**
+- If `GODOG_TAGS` is not set, the test uses the default tag filter: `~@flaky && ~@todo && ~@skip`
+- If `GODOG_STOP_ON_FAILURE` is not set, each feature uses its default:
+  - `jwt`, `greet`, `auth`, `health`: `true` (stop on failure)
+  - `config`, `all features`: `false` (continue after failures)
+
+## Usage Examples
+
+### Running Smoke Tests
+```bash
+# Run all smoke tests
+godog --tags=@smoke features/
+
+# Run smoke tests for specific feature
+godog --tags=@smoke features/auth/
+```
+
+### Running Critical Tests
+```bash
+# Run all critical tests
+godog --tags=@critical features/
+
+# Run critical health tests
+godog --tags=@critical,@health features/
+```
+
+### Running Feature-Specific Tests
+```bash
+# Run all auth tests
+godog --tags=@auth features/
+
+# Run v2 API tests
+godog --tags=@v2 features/
+```
+
+### Combining Tags
+```bash
+# Run smoke tests for auth and health features
+godog --tags=@smoke,@auth,@health features/
+
+# Run critical API tests
+godog --tags=@critical,@api features/
+```
+
+## Tagging Conventions
+
+1. **Feature tags** should be applied at the feature level
+2. **Priority tags** should be applied at the scenario level
+3. **Component tags** should be applied at the scenario level
+4. **Multiple tags** can be applied to a single scenario
+
+### Example Feature File
+```gherkin
+@health @smoke
+Feature: Health Endpoint
+  The health endpoint should indicate server status
+
+  @basic @critical
+  Scenario: Health check returns healthy status
+    Given the server is running
+    When I request the health endpoint
+    Then the response should be "{\"status\":\"healthy\"}"
+
+  @advanced @api
+  Scenario: Health check with authentication
+    Given the server is running with auth enabled
+    When I request the health endpoint with valid token
+    Then the response should be "{\"status\":\"healthy\"}"
+```
+
+## Test Execution Scripts
+
+### Feature-Specific Testing
+```bash
+# Test specific feature
+./scripts/test-feature.sh greet
+
+# Test with specific tags
+./scripts/test-by-tag.sh @smoke greet
+```
+
+### Tag-Based Testing
+```bash
+# Run smoke tests for all features
+./scripts/test-by-tag.sh @smoke
+
+# Run critical auth tests
+./scripts/test-by-tag.sh @critical auth
+```
+
+## CI/CD Integration
+
+### Smoke Test Pipeline
+```yaml
+- name: Run Smoke Tests
+  run: godog --tags=@smoke features/
+```
+
+### Critical Path Testing
+```yaml
+- name: Run Critical Tests
+  run: godog --tags=@critical features/
+```
+
+### Feature-Specific Testing
+```yaml
+- name: Test Auth Feature
+  run: ./scripts/test-feature.sh auth
+```
+
+## Best Practices
+
+1. **Tag consistently** - Apply tags consistently across similar scenarios
+2. **Prioritize tests** - Use priority tags to identify critical tests
+3. **Document tags** - Keep this documentation updated with new tags
+4. **Review tags** - Regularly review tag usage to ensure relevance
+5. **CI/CD optimization** - Use tags to optimize CI/CD pipeline execution times
+
+## Tag Reference
+
+| Tag | Purpose | Example Usage |
+|-----|---------|--------------|
+| `@smoke` | Smoke tests | `@smoke` on critical features |
+| `@critical` | Critical path | `@critical` on essential scenarios |
+| `@basic` | Basic functionality | `@basic` on standard scenarios |
+| `@advanced` | Advanced scenarios | `@advanced` on edge cases |
+| `@nice_to_have` | Optional features | `@nice_to_have` on stretch goal scenarios |
+| `@auth` | Authentication | `@auth` on auth features |
+| `@config` | Configuration | `@config` on config scenarios |
+| `@api` | API endpoints | `@api` on endpoint tests |
+| `@v2` | V2 API | `@v2` on version 2 tests |
+| `@flaky` | Exclude flaky tests | `@flaky` on unstable scenarios |
+| `@todo` | Exclude pending tests | `@todo` on unimplemented scenarios |
+| `@skip` | Exclude tests entirely | `@skip` on disabled scenarios |
+| `@wip` | Work in progress | `@wip` on actively developed scenarios |
+
+## Future Enhancements
+
+- **Performance tags** - `@fast`, `@slow` for performance categorization
+- **Environment tags** - `@ci`, `@local` for environment-specific tests
+- **Risk tags** - `@high-risk`, `@low-risk` for risk-based testing
+- **Automated tag validation** - Script to validate tag usage consistency

+Feature: JWT Secret Retention Policy
+  As a system administrator
+  I want automatic cleanup of expired JWT secrets
+  So that we can maintain security while ensuring system performance
+
+  Background:
+    Given the server is running with JWT secret retention configured
+    And the default JWT TTL is 24 hours
+    And the retention factor is 2.0
+    And the maximum retention is 72 hours
+
+  Scenario: Automatic cleanup of expired secrets
+    Given a primary JWT secret exists
+    And I add a secondary JWT secret with 1 hour expiration
+    When I wait for the retention period to elapse
+    Then the expired secondary secret should be automatically removed
+    And the primary secret should remain active
+    And I should see cleanup event in logs
+
+  Scenario: Secret retention based on TTL factor
+    Given the JWT TTL is set to 2 hours
+    And the retention factor is 3.0
+    When I add a new JWT secret
+    Then the secret should expire after 6 hours
+    And the retention period should be 6 hours
+
+  Scenario: Maximum retention period enforcement
+    Given the JWT TTL is set to 72 hours
+    And the retention factor is 3.0
+    And the maximum retention is 72 hours
+    When I add a new JWT secret
+    Then the retention period should be capped at 72 hours
+    And not exceed the maximum retention limit
+
+  Scenario: Cleanup preserves primary secret
+    Given a primary JWT secret exists
+    And the primary secret is older than retention period
+    When the cleanup job runs
+    Then the primary secret should not be removed
+    And the primary secret should remain active
+
+  @todo
+  Scenario: Multiple secrets with different ages
+    Given I have 3 JWT secrets of different ages
+    And secret A is 1 hour old (within retention)
+    And secret B is 50 hours old (expired)
+    And secret C is the primary secret
+    When the cleanup job runs
+    Then secret A should be retained
+    And secret B should be removed
+    And secret C should be retained as primary
+
+  @todo
+  Scenario: Cleanup frequency configuration
+    Given the cleanup interval is set to 30 minutes
+    When I add an expired JWT secret
+    Then it should be removed within 30 minutes
+    And I should see cleanup events every 30 minutes
+
+  @todo
+  Scenario: Token validation with expired secret
+    Given a user "retentionuser" exists with password "testpass123"
+    And I authenticate with username "retentionuser" and password "testpass123"
+    And I receive a valid JWT token signed with current secret
+    When I wait for the secret to expire
+    And I try to validate the expired token
+    Then the token validation should fail
+    And I should receive "invalid_token" error
+
+  @todo
+  Scenario: Graceful rotation during retention period
+    Given a user "gracefuluser" exists with password "testpass123"
+    And I authenticate with username "gracefuluser" and password "testpass123"
+    And I receive a valid JWT token signed with primary secret
+    When I add a new secondary secret and rotate to it
+    And I authenticate again with username "gracefuluser" and password "testpass123"
+    Then I should receive a new token signed with secondary secret
+    And the old token should still be valid during retention period
+    And both tokens should work until retention period expires
+
+  Scenario: Configuration validation
+    Given I set retention factor to 0.5
+    When I try to start the server
+    Then I should receive configuration validation error
+    And the error should mention "retention_factor must be ≥ 1.0"
+
+  @todo @nice_to_have
+  Scenario: Metrics for secret retention
+    Given I have enabled Prometheus metrics
+    When the cleanup job removes expired secrets
+    Then I should see "jwt_secrets_expired_total" metric increment
+    And I should see "jwt_secrets_active_count" metric decrease
+    And I should see "jwt_secret_retention_duration_seconds" histogram update
+
+  @todo @nice_to_have
+  Scenario: Log masking for security
+    Given I add a new JWT secret "super-secret-key-123456"
+    When the cleanup job runs
+    Then the logs should show masked secret "supe****123456"
+    And not expose the full secret in logs
+
+  @todo
+  Scenario: Cleanup with high volume of secrets
+    Given I have 1000 JWT secrets
+    And 300 of them are expired
+    When the cleanup job runs
+    Then it should complete within 100 milliseconds
+    And remove all 300 expired secrets
+    And not impact server performance
+
+  @todo
+  Scenario: Disabled cleanup via configuration
+    Given I set cleanup interval to 8760 hours
+    When I add expired JWT secrets
+    Then they should not be automatically removed
+    And manual cleanup should still be possible
+
+  @todo
+  Scenario: Retention period calculation edge cases
+    Given the JWT TTL is 1 hour
+    And the retention factor is 1.0
+    When I add a new JWT secret
+    Then the retention period should be 1 hour
+    And the secret should expire after 1 hour
+
+  @todo
+  Scenario: Secret validation with retention policy
+    Given I try to add an invalid JWT secret
+    When the secret is less than 16 characters
+    Then I should receive validation error
+    And the error should mention "must be at least 16 characters"
+
+  @todo
+  Scenario: Cleanup job error handling
+    Given the cleanup job encounters an error
+    When it tries to remove a secret
+    Then it should log the error
+    And continue with remaining secrets
+    And not crash the cleanup process
+
+  @todo
+  Scenario: Configuration reload without restart
+    Given the server is running with default retention settings
+    When I update the retention factor via configuration
+    Then the new settings should take effect immediately
+    And existing secrets should be reevaluated
+    And cleanup should use new retention periods
+
+  @todo @nice_to_have
+  Scenario: Audit trail for secret operations
+    Given I enable audit logging
+    When I add a new JWT secret
+    Then I should see audit log entry with event type "secret_added"
+    And when the secret is removed by cleanup
+    Then I should see audit log entry with event type "secret_removed"
+
+  @todo
+  Scenario: Retention policy with token refresh
+    Given a user "refreshuser" exists with password "testpass123"
+    And I authenticate and receive token A
+    When I refresh my token during retention period
+    Then I should receive new token B
+    And token A should still be valid until retention expires
+    And both tokens should work concurrently
+
+  @todo
+  Scenario: Emergency secret rotation
+    Given a security incident requires immediate rotation
+    When I rotate to a new primary secret
+    Then old tokens should be invalidated immediately
+    And new tokens should use the emergency secret
+    And cleanup should remove compromised secrets
+  
+  @todo @nice_to_have
+  Scenario: Monitoring and alerting
+    Given I have monitoring configured
+    When the cleanup job fails repeatedly
+    Then I should receive alert notification
+    And the alert should include error details
+    And suggest remediation steps

-# 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

+# BDD Test Configuration Schema
+
+## Overview
+
+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

+
+## 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
+
+```

+2026-04-11T10:10:53.146438 | auth            | User registration               | SCENARIO_END     | PASSED
+2026-04-11T10:10:53.152398 | auth            | User registration               | JWT_RESET        | ok

+```
+
+## 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
+

+
+**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"
+  ```
