EU AI Act–NIST–ISO compliance crosswalk template

I’ve compiled a v0.9 crosswalk mapping EU AI Act obligations (Annex IV technical documentation, risk management, and post‑market monitoring) to NIST AI RMF 1.1 and ISO/IEC 42001:2023 for teams operationalizing governance. If you want the template or can sanity‑check the mappings — and suggest additions for UK AISI, Singapore AI Verify, or Canada’s AIDA — to help drive consistent compliance and informed policy advocacy, say so and I’ll share the latest (updated Dec 2025).

I’ve found one tweak that pays off: add an Evidence column that names the exact artifact IDs you’d hand to an auditor for each EU AI Act item (risk register entry, validation protocol, “post‑market monitoring” ticket) and cross‑ref ISO/IEC 42001 cl. 9.1/10.2 and NIST AI RMF Measure/Manage rows. Small caveat: don’t collapse “intended purpose” across variants — track it per deployment so your risk class and Annex IV scope don’t drift; want a sample schema?
