All content is authored as original study notes (concept cards, summaries, practice questions). Official third-party course materials — Tricentis exercise workbooks, transcripts, and Tosca subset (.tsu) files — are not included in this repository; the relevant modules link to the official Tricentis Academy courses instead.

Adding content

1. Create a module JSON in data/business-architect/ or data/system-architect/ following the schema of existing files (studyGuide, examPitfalls, practiceQuiz, quickRecap).
2. Register it in data/registry.json with "ready": true.

The UI renders it automatically — no code changes needed.
