A slow filesystem could stall the writer's receive pipeline, propagating TCP backpressure to the pusher. The pusher's 3s per-frame send deadline then treated that backpressure as a dead peer and force-closed the connection mid-run. The writer reconnected as a brand-new connection that was not part of the active session, so the rest of the run was silently dropped and the half-written HDF5 file was later finalized with holes. Replace the throughput-based send timeout with a peer-liveness timeout: - Add TCPFrameType::BUSY (wire version 2 -> 3). - TCPImagePuller runs a heartbeat thread that sends BUSY every 250ms on a thread independent of the stalled write path, so liveness keeps flowing during deep stalls. A send_mutex serializes ACK/pong/heartbeat writes. - TCPStreamPusher refreshes last_peer_activity on every inbound frame and only declares a connection dead after peer_liveness_timeout (15s) of complete silence, tolerating arbitrarily long backpressure while still catching a genuinely dead peer (and immediate EPIPE/ECONNRESET).
