gtg.se zoominfo.com/c/göteborgsregionens-tekniska-gymnasium/458572877 GTG technical upper-secondary school (gymnasium) owned by 13 Gothenburg-area municipalities (via the Göteborgsregionens kommunalförbund) — founded in 2006 specifically to solve the region's engineering talent shortage, the first inter-municipal school of its kind in Sweden. Located inside Lindholmen Science Park next to Chalmers, Volvo, SKF and Saab — a genuine "school inside an industrial cluster" with guest lectures, real projects, internships and equipment from industry partners. Programs: Teknikprogrammet (design & product development, production, IT/media tech) and El- och energiprogrammet (automation, electricity, energy) — ~700–900 students, tuition-free, with graduates feeding directly into Chalmers engineering programs or industrial apprenticeships.

Evidence ladder
Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.
