 # Redis Connection Capability Specification
 
 ## Overview
+
 This specification defines the Redis connection capability for the BLS Project Console, which manages the connection between the system and the Redis server for reading logs and sending commands.
 
 ## Requirements
 
 ### Requirement: Redis Connection Establishment
+
 The system SHALL establish a connection to the Redis server.
 
 #### Scenario: Establishing Redis connection on server start
+
 - **WHEN** the server starts
 - **THEN** it SHALL attempt to connect to the Redis server
 - **AND** it SHALL log the connection status
 
 ### Requirement: Redis Connection Configuration
+
 The system SHALL allow configuration of Redis connection parameters.
 
 #### Scenario: Configuring Redis connection via environment variables
+
 - **WHEN** the server starts with Redis environment variables set
 - **THEN** it SHALL use those variables to configure the Redis connection
 - **AND** it SHALL override default values
 
 ### Requirement: Redis Connection Reconnection
+
 The system SHALL automatically reconnect to Redis if the connection is lost.
 
 #### Scenario: Reconnecting to Redis after connection loss
+
 - **WHEN** the Redis connection is lost
 - **THEN** the system SHALL attempt to reconnect with exponential backoff
 - **AND** it SHALL log each reconnection attempt
 - **AND** it SHALL notify the user when connection is restored
 
 ### Requirement: Redis Connection Error Handling
+
 The system SHALL handle Redis connection errors gracefully.
 
 #### Scenario: Handling Redis connection failure
+
 - **WHEN** the system fails to connect to Redis
 - **THEN** it SHALL log the error
 - **AND** it SHALL display an error message to the user
 - **AND** it SHALL continue attempting to reconnect
 
 ### Requirement: Redis Connection Monitoring
+
 The system SHALL monitor the Redis connection status.
 
 #### Scenario: Monitoring Redis connection status
+
 - **WHEN** the Redis connection status changes
 - **THEN** the system SHALL update the connection status in the UI
 - **AND** it SHALL log the status change
