## What this repository is

This repository is not an application source-code release or a question-bank download. It is a **knowledge base, implementation methodology, and AI skill**. You can use it as an operating guide for agents that support `SKILL.md`, or as a practical blueprint for product managers, designers, and engineers building similar systems.

It provides:

- A nine-stage pipeline from source audit to product delivery - Decision cards for vision-model selection, batch transcription, and cost estimation - Validation rules that prevent alignment errors, truncation, and AI-generated content drift - Information architecture, interaction, and visual-design lessons for desktop practice products - A reusable design for answer-key-driven controls, local grading, persistence, and mistake review - A troubleshooting guide organized as **symptom → root cause → fix
