crovia 0.2.0

Crovia — The Global Standard for AI Training Data Attribution. Cryptographic proofs, absence verification, and automatic royalty settlement.

Crovia Core Engine (Open Core)

If AI is trained on your data, there should be a receipt.

Crovia is an offline-verifiable evidence engine for declared AI training data.

It does not accuse.
It does not infer intent.
It does not enforce compliance.

Crovia produces deterministic artifacts that anyone can verify independently.

Read this first (30 seconds)

If you read only one thing, read this:

Crovia turns a declaration into a closed, verifiable evidence capsule.
Nothing more. Nothing less.

No trust required.
No network required.
No hidden logic.

What Crovia produces (CRC-1)

Crovia generates a CRC-1 Evidence Pack — a closed set of files that fully describe:

• what was declared
• what was produced
• how integrity can be verified

Each CRC-1 pack contains:

• receipts.ndjson — declared training receipts
• validate_report.md — deterministic validation result
• hashchain.txt — integrity hash-chain
• trust_bundle.json — normalized trust summary
• MANIFEST.json — authoritative artifact contract

All files are offline-verifiable.

Specification:
docs/CROVIA_ARTIFACT_SPEC.md

---

Try it (single command)

Generate a complete CRC-1 Evidence Pack:

# Unified CLI
crovia run --period 2025-11 --budget 100000

# Or with custom receipts
crovia run \
  --receipts examples/minimal_royalty_receipts.ndjson \
  --period 2025-11 \
  --out out_crc1

Other commands:

crovia status    # Check system status
crovia test      # Run module tests
crovia score     # Calculate Crovia Score

This creates a fully self-contained evidence capsule in out_crc1/.

• No network
• No secrets
• Fully deterministic

---

Inspect the artifacts

Example:

ls out_crc1
cat out_crc1/MANIFEST.json

MANIFEST.json defines exactly which files must exist.

Nothing implicit.
Nothing hidden.

---

Verify evidence (offline, by anyone)

Verification requires only the files themselves.

Example:

crovia-verify out_crc1

Expected result:

✔ All artifacts present
✔ trust_bundle JSON valid
✔ Hashchain verified

✔ CRC-1 VERIFIED

If verification fails, the evidence is invalid.

No trust assumptions.
No authority required.

---

Design principles

• Offline-first
• Deterministic
• No attribution claims
• No enforcement logic
• Evidence > opinions

Crovia produces facts, not judgments.

---

Where to see real evidence

Crovia Open Core does not ship conclusions.

All public, inspectable evidence generated with this engine lives here:

https://github.com/croviatrust/crovia-evidence-lab

That repository contains:

• reproducible CRC-1 capsules
• offline-verifiable artifacts
• neutral semantic observations (DSSE)
• presence / absence observations (Spider)

If you want to see results, go there.
If you want to reproduce them, stay here.
