Article 12 & 26(6)
High-risk AI systems must “technically allow for the automatic recording of events over the lifetime of the system,” and deployers must retain those logs for at least six months — a floor, not a target; sector law (AML, SOX, HIPAA) routinely demands longer. Article 17 adds a Quality Management System; Annex IV adds technical documentation.
The Act does not explicitly require cryptographic logs — but it does require completeness, integrity, and reconstruction. A mutable log fails all three. Runfile produces an Article 12 monthly log-integrity report as a single command.
The May 2026 Digital Omnibus moved standalone high-risk obligations to 2 Dec 2027 and embedded high-risk to 2 Aug 2028. Both are now fixed calendar dates, not standards-conditional.
