The viewer could grow to ~100 GB RAM when live-following an HTTP broker. The rc.153 images_in_flight backpressure only throttled imageLoaded; the heavy per-frame payload rides datasetLoaded, fanned out over ~10 queued cross-thread connections with no cap. In HTTPSyncDataset follow mode (entered when an operator clicks an image while following live) RefreshDatasetOnly_i emits a fresh full dataset every autoload tick with no imageLoaded, so the gate never engaged and the queued events - each pinning a full JFJochReaderDataset (full-detector PixelMask + per-image plots) - accumulated without bound. Backpressure datasetLoaded the same way as imageLoaded: a datasets_in_flight counter (cap 2), all emits routed through EmitDatasetLoaded_i, and AutoLoadTimerExpired gated on it (covers HTTPSyncDataset). The window routes the worker's datasetLoaded through a single OnDatasetReady sink that fans out synchronously via datasetReady and acks with datasetConsumed. Under load stale datasets are dropped; the next tick sends the latest. Share the pixel mask instead of deep-copying it: JFJochReaderDataset::pixel_mask is now shared_ptr<const PixelMask>, so per-frame dataset copies share the ~72 MB mask. UpdateUserMask does copy-on-write; JFJochHttpReader caches the mask by arm_date so a live refresh reuses one shared mask per acquisition. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
