…otocol#6) Decouples telemetry ingestion from the canvas draw loop so 50+ msg/s bursts no longer drop frames or cause tab unresponsiveness. - utils/buffer.ts: RingBuffer (fixed MAX_POINTS=200 capacity, slice(-cap) eviction, runtime setCapacity), StreamBatcher (accumulate writes, flush into the ring every BATCH_INTERVAL=50ms; injectable clock), and AdaptiveCapacityMonitor (shrinks the window after frames exceed 33ms / <30 FPS, grows back when healthy) - utils/helpers.ts: throttle<T>(fn, wait) (leading + trailing) plus debounce - components/spatial/LiveDataView.tsx: routes ingestion through the batcher, the RAF draw loop reads the ring buffer directly (no React state on the hot path) and feeds frame time to the CPU monitor to adapt capacity; ResizeObserver updates are throttled - tests for the ring buffer, batching/flush timing, the adaptive monitor, and throttle/debounce Test file lives under tests/unit (vitest only collects tests/**, not src/__tests__).
