# CROVIA · Evidence Machine

**The world's first AI forensic evidence console.**

Type any AI model. Get a complete, cryptographically anchored, temporally verified evidence package showing exactly what training data documentation exists — and what doesn't.

## What this does

- **200+ models monitored** with 20 NEC# documentation requirements each
- **Pedersen commitments** anchor every observation cryptographically
- **Chain height 3,000+** — continuous, append-only temporal proof
- **Regulatory mapping** — jurisdictions affected by each documentation gap
- **Citation engine** — one-click, legal-grade evidence statements
- **Outreach tracking** — was the organization contacted? Did they respond?
- **Peer comparison** — how does this model compare to its organization and industry?

## How to use

1. Type a model ID (e.g. `google/gemma-3-12b-it`) in the command bar
2. Click **INVESTIGATE**
3. Read the signal strip, NEC# constellation, forensic report, and citation

## What you see

- **Signal Strip** — Trust level, evidence strength, chain height, NEC# gaps, jurisdictions
- **NEC# Constellation** — Interactive SVG showing all 20 documentation requirements as nodes
- **NEC# Grid** — Color-coded grid of present/absent/critical elements
- **Forensic Report** — Full monospace report with cryptographic anchors
- **Jurisdictions** — Which regulations apply to the observed gaps
- **Citation Engine** — Copy-paste evidence statement for legal or journalistic use

## CEP Capsules tab

## Important

This is observation, not judgment. All data derived from publicly observable artifacts.
No model audit. No legal claim. Presence/absence only.
