+Feature: Race Event Performance Summary Notifications
+
+  As a driver
+  I want to receive performance summary notifications after races
+  So that I can see my results and rating changes immediately
+
+  Background:
+    Given a league exists with stewarding configuration
+    And a season exists for that league
+    And a race event is scheduled with practice, qualifying, and main race sessions
+
+  Scenario: Driver receives performance summary after main race completion
+    Given I am a registered driver for the race event
+    And all sessions are scheduled
+    When the main race session is completed
+    Then a MainRaceCompleted domain event is published
+    And I receive a race_performance_summary notification
+    And the notification shows my position, incidents, and provisional rating change
+    And the notification has modal urgency and requires no response
+
+  Scenario: Driver receives final results after stewarding closes
+    Given I am a registered driver for the race event
+    And the main race has been completed
+    And the race event is in awaiting_stewarding status
+    When the stewarding window expires
+    Then a RaceEventStewardingClosed domain event is published
+    And I receive a race_final_results notification
+    And the notification shows my final position and rating change
+    And the notification indicates if penalties were applied
+
+  Scenario: Practice and qualifying sessions don't trigger notifications
+    Given I am a registered driver for the race event
+    When practice and qualifying sessions are completed
+    Then no performance summary notifications are sent
+    And the race event status remains in_progress
+
+  Scenario: Only main race completion triggers performance summary
+    Given I am a registered driver for the race event
+    And the race event has practice, qualifying, sprint, and main race sessions
+    When the sprint race session is completed
+    Then no performance summary notification is sent
+    When the main race session is completed
+    Then a performance summary notification is sent
+
+  Scenario: Provisional rating changes are calculated correctly
+    Given I finished in position 1 with 0 incidents
+    When the main race is completed
+    Then my provisional rating change should be +25 points
+    And the notification should display "+25 rating"
+
+  Scenario: Rating penalties are applied for incidents
+    Given I finished in position 5 with 3 incidents
+    When the main race is completed
+    Then my provisional rating change should be reduced by 15 points
+    And the notification should show the adjusted rating change
+
+  Scenario: DNF results show appropriate rating penalty
+    Given I did not finish the race (DNF)
+    When the main race is completed
+    Then my provisional rating change should be -10 points
+    And the notification should display "DNF" as position
+
+  Scenario: Stewarding close mechanism works correctly
+    Given a race event is awaiting_stewarding
+    And the stewarding window is configured for 24 hours
+    When 24 hours have passed since the main race completion
+    Then the CloseRaceEventStewardingUseCase should close the event
+    And final results notifications should be sent to all participants
+
+  Scenario: Race event lifecycle transitions work correctly
+    Given a race event is scheduled
+    When practice and qualifying sessions start
+    Then the race event status becomes in_progress
+    When the main race completes
+    Then the race event status becomes awaiting_stewarding
+    When stewarding closes
+    Then the race event status becomes closed
+
+  Scenario: Notifications include proper action buttons
+    Given I receive a performance summary notification
+    Then it should have a "View Full Results" action button
+    And clicking it should navigate to the race results page
+
+  Scenario: Final results notifications include championship standings link
+    Given I receive a final results notification
+    Then it should have a "View Championship Standings" action button
+    And clicking it should navigate to the league standings page
+
+  Scenario: Notifications are sent to all registered drivers
+    Given 10 drivers are registered for the race event
+    When the main race is completed
+    Then 10 performance summary notifications should be sent
+    When stewarding closes
+    Then 10 final results notifications should be sent
+
+  Scenario: League configuration affects stewarding window
+    Given a league has stewardingClosesHours set to 48
+    When a race event is created for that league
+    Then the stewarding window should be 48 hours after main race completion
