 - 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
