AI Act conformity assessment for internal HR analytics tools — where to start?

The EU AI Act classifies certain HR analytics systems as high-risk. We have an internal tool that scores employee engagement and flags retention risk. Not sure if this crosses into high-risk territory. What we're trying to figure out: - Does an internal-only employee analytics tool count as a "high-risk AI system" under Annex III? - If yes, what does the conformity assessment process actually look like for a company that isn't placing the system on the market? - Are teams building a technical documentation file from scratch, or is there a template/standard that maps to the AI Act requirements? Jurisdiction: DE/EU Looking for peer experiences from teams that went through this. Not seeking legal advice.
