Spec Delta: User Presence Tracking
Change ID: add-presence-tracking
Capability: User Presence Tracking
Type: NEW
ADDED Requirements
User Session Management
Requirement: Server shall create and track user sessions
Description: When user connects with valid token, server creates session tracking user identity, connection state, and lifetime.
Priority: High Status: Proposed
Scenarios:
Scenario: User session created on connection
Given: Client connects with valid token
When: gRPC connection established
Then: Server creates new session
And: Session includes: user_id, session_id, connected_at
And: User marked as ONLINE
And: Session persists for connection lifetime
Scenario: Session destroyed on disconnect
Given: User has active session
When: Connection is closed
Then: Server destroys session
And: User marked as OFFLINE
And: UserOffline event broadcast
And: Channel membership updated
Presence Status
Requirement: Server shall track and broadcast user presence status
Description: Users have status: ONLINE, IDLE, OFFLINE. Status is tracked and broadcast to all connected clients.
Priority: High Status: Proposed
Details:
- ONLINE: Connected and active
- IDLE: Connected but inactive 5+ minutes
- OFFLINE: Not connected
- Future: DO_NOT_DISTURB, AWAY
Scenarios:
Scenario: User status transitions
Given: User just connected
Then: Status is ONLINE
When: User inactive for 5 minutes
Then: Status changes to IDLE
When: User takes action
Then: Status returns to ONLINE
Scenario: Presence broadcast
Given: Users A and B connected to server
When: User A comes online
Then: User B receives UserOnline event
And: Event includes User A's presence info
And: User A appears in online user list for B
Idle Detection
Requirement: Server shall detect and mark idle users
Description: Background process monitors activity and marks users idle after 5 minutes of inactivity.
Priority: High Status: Proposed
Scenarios:
Scenario: Idle detection after timeout
Given: User connected but inactive for 5 minutes
When: Server checks for idle users
Then: User marked as IDLE status
And: UserStatusChanged event broadcast
And: Other users see user as idle
Scenario: Activity resumes
Given: User is IDLE
When: User takes any action (join channel, send message, etc)
Then: User marked as ONLINE again
And: Idle timer reset
Channel Presence
Requirement: Server shall track which channel users are in
Description: Presence includes current channel. Updated when user joins/leaves channel.
Priority: High Status: Proposed
Scenarios:
Scenario: Channel presence tracked
Given: User joins "general" channel
When: Server updates user presence
Then: Presence includes: current_channel_id = "general"
And: UserChannelChanged event broadcast
And: Other users see user in "general"
When: User leaves "general" and joins "announcements"
Then: Presence updated: current_channel_id = "announcements"
And: UserChannelChanged event broadcast
Mute Status
Requirement: Server shall track microphone and speaker mute state
Description: Presence includes mute status for microphone and speaker. Updated when user toggles mute.
Priority: High Status: Proposed
Scenarios:
Scenario: User mutes microphone
Given: User in voice channel with microphone active
When: User toggles microphone mute
Then: Server receives mute status update
And: Presence updated: is_microphone_muted = true
And: UserMuteStateChanged event broadcast
And: Other channel members see user as muted
Scenario: Multiple mute states
Given: User in channel
When: User mutes microphone only
Then: is_microphone_muted = true, is_speaker_muted = false
When: User also mutes speakers
Then: is_microphone_muted = true, is_speaker_muted = true
Online User List
Requirement: Clients can query list of all online users
Description: Clients can retrieve real-time list of all currently online users with their presence details.
Priority: High Status: Proposed
Scenarios:
Scenario: Get online users list
Given: Server has 5 online users
When: Client requests ListOnlineUsers
Then: Response includes all 5 users
And: Each user includes: user_id, status, current_channel, mute_state
And: Response is current (not stale)
Channel Member Presence
Requirement: Clients can query presence of channel members
Description: Get presence information for all members in specific channel.
Priority: High Status: Proposed
Scenarios:
Scenario: Get channel members with presence
Given: Channel "general" has 3 members
When: Client requests ListChannelMembers with channel_id
Then: Response includes all 3 members
And: Each includes: user_id, status, microphone_muted, speaker_muted
And: Presence info helps UI show who can talk
Presence Events
Requirement: Server broadcasts presence changes to all clients
Description: Real-time events notify clients when presence changes.
Priority: High Status: Proposed
Scenarios:
Scenario: Presence event broadcast
Given: Client A subscribed to presence events
When: User B comes online
Then: Client A receives UserOnlineEvent
And: Event includes User B's full presence
And: Event includes timestamp
When: User C changes channel
Then: UserChannelChangedEvent broadcast
And: Subscribers notified immediately
