SignalProof
An evidence-first low-voltage signal quality workbench that computes six deterministic metrics (DC offset, AC RMS, rail clipping, 48-52 Hz mains hum, timing jitter and capture duration) before validating bilingual explanations against fixed finding IDs.

What I built
An evidence-first low-voltage signal quality workbench that computes six deterministic metrics (DC offset, AC RMS, rail clipping, 48-52 Hz mains hum, timing jitter and capture duration) before validating bilingual explanations against fixed finding IDs.
Developed with AI coding assistance. Source code, reproduction instructions, a 3-minute narrated walkthrough on YouTube and tests are available via the links above.
What was checked
Verified with 60 passing Node.js tests, 15/15 synthetic evaluation scenarios, and 520 archived synthetic inference records (1,313,133 tokens across Baseten & Fireworks).
Verification date: 7 November 2026. Tests cover the included fixtures and recorded audit traces and do not establish production performance.
What this demonstrates
Validates signal quality rules on synthetic and CSV bench captures (0.0-3.3 V default range). Passing deterministic checks and recorded LLM audit replays do not establish calibrated oscilloscope accuracy or hardware safety.
