feat(telemetry): inject Tick-to-Pixel IPC JitterCharts and Desktop Notification stream

quantDIY · quantDIY · commit ca3f777fa013 · 2026-02-24T01:06:33.000-05:00
Built the Epoch 10 Ref-Buffer validation graphs across GUI targets to prove &lt;1ms transmission limits. Wired native OS system tray triggers on Rust to confirm zero-drop IPC ingestion boundaries.

+## Epoch 10: The Pulse of the Machine
+
+The Brawn (C++), the Nerves (Tauri/Rust), and the Retina (React HTML5 Canvas) are fundamentally connected. We built the `JitterChart` to mathematically prove the determinism gained from the "Dead Core" sacrifice.
+
+By plotting the exact delta between the C++ Time Stamp Counter (`arrival_tsc`) and the React `requestAnimationFrame` loop (`render_tsc`), we visualize the absolute total pipeline latency. On the Desktop (IPC Bypass), this should produce a perfectly flat oscilloscope trace representing the unadulterated heartbeat of the machine. On the Web, it demonstrates the structural cost of the GraphQL "Strawberry" Relay transmission. 
+
+We do not approximate performance; we measure it down to the exact nanosecond cycle. The UI is calibrated.
