Socket timeout exception during Twitter API v2 filtered stream termination

Stream Termination Behavior
Twitter API v2 streaming endpoints, such as the filtered tweet stream, rely on the client closing the TCP connection to terminate the data flow. Because there is no dedicated API-level cancellation signal or subscription identifier to send a DELETE request, clients must manage the lifecycle via the transport layer.
Connection State Uncertainty
When a client-side read timeout triggers a socket timeout exception, the HTTP connection may enter a half-closed state. This creates a scenario where the server continues to transmit data until it detects a broken pipe, potentially leading to inefficient network utilization and resource leakage on the client side.
Given the reliance on HTTP/1.1 or HTTP/2 for these long-running connections, it is unclear how the server-side state is synchronized with client-side timeouts.
- Does the Twitter API v2 server immediately cease transmission upon a TCP FIN packet, or is there a grace period?
- Is there a documented method to ensure a graceful teardown that avoids half-closed socket states?
