GHUL update – frontend work in progress 🧪📊

Right now I’m developing the GHULbenchmark GUI locally on my own machine.
The focus is not “pretty graphs”, but measurement correctness.

The visualizer already detects sensor glitches (they always happen),
marks them as outliers, and filters them out for calculations and analysis –
so averages, peaks and ratings stay meaningful.

This is slowly turning into a real measurement lab instead of a gaming dashboard.
First impression attached. More to come.

Why “Aging” Makes Switches Reliable
We burn-in switches at 50℃±5℃ to catch early flaws & ensure they endure real-world heat—before they reach you. No weak links, just lasting performance. 🌡️⚙️

Tested Next.js native deps on riscv64 hardware (Banana Pi F3). Results:

✅ Sharp WASM: Production-ready (604ms resize 1920×1080, zero crashes)
❌ Prisma: Broken (WASM parser bug, no fix)

Hardware testing beats speculation. 2,400+ lines of docs updated with real numbers.

The JieLi (JL) Bluetooth Test Box is a must-have for hardware teams! It supports:
🔸 Parallel testing of 2 devices (4+ recommended for efficiency)
🔸 Configurable tests via dip-switch (music playback, call frequency deviation)
🔸 Clear displays for device name, status (🎵/📞), and real-time frequency data
🔸 Physical buttons for playback control (pause, skip, volume)

Ideal for production line validation!
