 Course codes, names, and scheduled semesters were checked on 18 October 2026 against the [official AIN-B module handbook](https://www.th-deg.de/Studierende/Antraege-und-Organisatorisches/Modulhandbuecher/modulhandbuch-ain-b-ws25-26.pdf) (document dated 7 September 2026; Internet Technologies p. 33, Assistance Systems p. 51, Machine Learning p. 67, Computer Vision p. 70, Deep Learning/Big Data p. 93). The [2023 handbook](https://cs-mariakirchen.th-deg.de/Studierende/Antraege-und-Organisatorisches/Modulhandbuecher/Module%20Handbooks/modulhandbuch-ain-b-en.pdf) also identifies these modules in the original cohort curriculum.
 
-Project associations use the creators' confirmation and repository evidence: [CheXVision README](https://github.com/arudaev/chexvision#readme), [Mini README](https://github.com/arudaev/chexvision-mini#readme), [Painfully Trivial README](https://github.com/arudaev/Painfully-Trivial#readme), and [Devablos prototype README](https://github.com/THD-AI/Devablos-Project#readme). Alexander confirmed the Assistance Systems association for Apero and both course associations for Painfully Trivial. Its README explicitly records Machine Learning; the Computer Vision association is creator-confirmed rather than a claim of a separate graded submission.

-The official course name is **Internet Technologies**, not Ethernet Technologies, and **Assistance Systems**. Rasa is a framework used by Apero, not a separate module. Project names, creator credits, original artwork, licences, and repository URLs are preserved. GitHub has no separate repository display-name field, so course-first names appear in descriptions, documentation, and the showroom.
+The official course name is **Internet Technologies**, not Ethernet Technologies, and **Assistance Systems**. Rasa is a framework used by Apero, not a separate module. Creator credits, original artwork, and licences are preserved. Organization course repositories now use course-first names containing their official module codes; historical GitHub links redirect to the renamed repositories. Personal upstream repositories retain their original names. THD Room Finder keeps its existing name as an independent campus project.
 
 Curricula can change. When adding coursework, provide the programme, exact module code, course name, scheduled semester, handbook edition, and evidence linking the project to the course. For personal work, leave course fields empty. Never infer an academic assignment from its technical subject alone.
