Title: Article 12 of the EU AI Act becomes applicable in 80 days — what cross-mappings to GDPR have you found most useful?

Body:

Hi r/europrivacy,

We have been running Article 12 logging in our own production system for about 14 months, and the GDPR cross-compliance turned out to be more subtle than I expected when I started.

A few mappings we use day to day:

Article 5(1)(c) data minimisation — we log SHA-256 hashes of inputs rather than raw inputs, with raw payloads encrypted in a separate tier under tighter retention.

Article 17 right to erasure — hash chain stays intact when we erase the linked tier (the hash does not reveal the data). The erasure event itself becomes a separate compliance log entry.

Article 30 RoPA — logging activities are listed as a distinct processing operation. Most internal RoPAs I see do not yet have this entry, but auditors are starting to expect it.

Article 35 DPIA — required for high-risk systems anyway. Logging design choices end up being a section in the DPIA itself.

What I am less sure about is the practical handling of cross-border logging when an EU-only deployment processes a flow that briefly touches a non-EU model provider. Anyone navigated that with their DPA at the supervisory authority?

I also wrote up the full set of patterns and templates into a practitioner toolkit, in case it is useful — bilingual DE/EN, 40-page PDF, five Excel templates, three checklists, 50+ JSON schemas. Launch price 29 euros: https://yoendem.gumroad.com/l/eu-ai-act-article-12-toolkit

Posting this here primarily for the discussion — happy to share specifics from our setup if useful.
