Real-Time Communication Audit

community-realtime · v1.1.0 · paid

Evaluates WebSocket/SSE implementation, message delivery reliability, presence indicators, connection handling, and real-time UX.

Connection Management

connection-management · weight 0.3

WebSocket connections require authentication before streaming
ab-000735
critical
Per-user connection limits enforced to prevent slot exhaustion
ab-000736
high
Heartbeat or ping on idle connections; zombie connections closed after configurable timeout
ab-000737
high
Exponential backoff with jitter on client reconnection, not fixed retry interval
ab-000738
high
Channel authorization re-validated on subscribe, not only at initial handshake
ab-000739
critical

Message Delivery & Ordering

message-delivery · weight 0.3

Each message carries a monotonic sequence number enabling gap detection
ab-000740
high
Duplicate messages deduplicated via client-generated ID before rendering
ab-000741
high
Pub/sub layer such as Redis or NATS ensures cross-instance message delivery
ab-000742
high
Messages queued server-side during disconnect and delivered in order on reconnection
ab-000743
medium
Max message payload size enforced server-side; oversized frames rejected with error
ab-000744
medium

Presence & State Sync

presence · weight 0.2

Presence state computed from server connection state, not forgeable client heartbeats
ab-000745
critical
Typing indicators debounced at client and expire server-side on timeout
ab-000746
medium
Read receipts stored as explicit user acknowledgment, not inferred from delivery
ab-000747
medium
Presence payloads contain only state and user ID; no IP, device, or session data leaked
ab-000748
medium
Real-time fan-out uses channel membership cache, not per-message permission reads
ab-000749
medium

Real-Time UX & Resilience

realtime-ux · weight 0.2

Connection state exposed to UI as connected, connecting, or disconnected indicator
ab-000750
low
Messages maintain causal order within a single thread; reply not emitted before parent
ab-000751
low
Client queues outbound messages while offline and re-sends on reconnect
ab-000752
low
Horizontal scaling confirmed: real-time state not held solely in process memory
ab-000753
low
Active connections, throughput, and queue depth exposed to observability layer
ab-000754
low
