# Catalog Maker by Magic AI

Node.js replacement for the Excel macro workflow behind the `Catalog maker - 20` button.

## Current Goal

Replace the Excel click workflow with a controlled Node.js pipeline:

1. Read local configuration from `config/local.json`.
2. Load or identify the source workbook.
3. Run catalog-maker steps in a safe order.
4. Default to dry-run mode.
5. Read from the database only. Database writes are forbidden.

## First Run

```powershell
copy config/local.example.json config/local.json
npm run catalog:dry-run
```

## Safety Rules

- Local secrets stay in `config/local.json`.
- `config/local.json` and Excel files are ignored by git.
- The app starts in dry-run mode.
- Rule #1: the database is read-only for this project.
- SQL guards must reject write statements before execution.

## Excel Entry Point Found

- Sheet: `endpoint`
- Button caption: `Catalog maker - 20`
- Internal control name: `CommandButton20`
- Approximate location: `A21:C22`
- ActiveX relation: `xl/activeX/activeX72.xml`

The exact VBA click handler still needs to be mapped before we implement real catalog generation logic.
