EU AI Act Article 53(1)(c) is the GPAI-provider duty to maintain a copyright policy that identifies and honours text-and-data-mining (TDM) rights reservations made under DSM Directive Art. 4(3). Machine-readable means (Recital 18) is the operative standard for online content; robots.txt/RFC 9309 is the only protocol named in the GPAI Code of Practice's Copyright chapter (Measure 1.3), while W3C TDMRep, Cloudflare Content Signals and IETF aipref are credible but unrecognised candidates, and llms.txt/ai.txt are not opt-outs at all. Kneschke v LAION (OLG Hamburg) held a reservation must be machine-actionable, not just machine-readable; GEMA v OpenAI shows the TDM exception does not shelter memorisation/regurgitation. Sourced from 3 files (1 skill + 2 references) in the eu-ai-act-tdm-opt-out skill, covering the DSM/AI-Act legal framework, the Code of Practice, case law, and the protocol layer.
