Two reports on running a private LLM over confidential material while staying legally defensible: a business assessment of on-prem vs. single-tenant rental vs. managed cloud against the "reasonable steps" test, and a technical reference architecture (threat model, VRAM sizing, hardening, control-to-law mapping). Built from public sources; not legal advice.
