Building PROTO RECON — From Vague Idea to a Browser-Based Tactical HUD

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.
