# Aradia Briefs — Sovereign AI Evidence Library

> Aradia Briefs: documented, cited, decision-shaped proof of why sovereign on-premises AI differs from public cloud AI. Court rulings, incident reports, and buying decisions — each with primary sources, cross-checked against our continuous Risk Monitor.

`>` Briefs / Sovereign AI Evidence Library — https://aradia.com/briefs/

Every claim we make has a brief behind it. Marketing says "private," "secure," "sovereign." We don't argue — we show the court rulings, the incident reports, and the invoices. If a cloud-AI failure has a name and a citation, it lives in this library.

## The Library

- **U.S. v. Heppner — public cloud AI waives privilege** (/briefs/law-firms/) — Law Firms / Court Ruling / 2026-02-17. Judge Rakoff, S.D.N.Y.: client facts pasted into Claude or ChatGPT are voluntary disclosure to a commercial vendor. What the ruling breaks, and the $15,125 air-gapped fix.
- More briefs land here as the Risk Monitor verifies new incidents. Machine-readable incident feed: https://aradia.com/api/incidents.json

## How a Brief Is Different From a Blog Post

- `//` **CITED, NOT OPINED** — Every brief traces to a primary source: a docket number, a ruling, an SEC filing, a published incident report. No "experts say." No vibes.
- `//` **MONITORED, NOT STALE** — Our continuous monitoring watches for the failures we warn about. When one is verified in the wild, it gets its own entry in the incident feed and its own brief.
- `//` **DECISION-SHAPED** — A brief ends at the decision: buy the Spark if…, the cloud works if…. Readable in five minutes by the person who signs the purchase order.
