Introduction

This post walks through how PROTO RECON — an experimental app that combines phone sensors with in-browser ML — evolved from pre-coding requirements to its current implementation. I've verified the UI behavior, but I'm still at the stage of reading the source code for the first time. Here I organize the original requirements and an AI-generated source map as a foundation for deeper dives in future posts.

Live demo (experimental) : Proto Recon (Cloudflare Workers)

Repository : github.com/katsutoshi0katsutoshi/proto_recon

Sandbox for isolated experiments : CodePen / @wlzpaovm-the-bashful

Note: This is still in testing. Performance tuning for heavy workloads hasn't been done yet — use at your own risk.

Where It Started
