# Synthetic Helix Evidence Bundle

This bundle is a synthetic, in silico sample artifact. It exists to show how a Helix evidence bundle can be inspected and verified locally.

It proves a narrow software property: the files in this directory match the SHA-256 hashes in `checksums.sha256`, and the core JSON artifacts include the required keys expected by the sample verifier.

It does not prove real-world effectiveness, real-world safety, diagnostics, treatment, or any real-world outcome. It is not a substitute for an internal review process.

## Contents

- `manifest.json`: bundle identity, file index, status, and claims boundary.
- `provenance_receipt.json`: source, run, environment, input, and artifact provenance.
- `evidence.json`: synthetic decision workflow evidence and policy results.
- `replay_report.json`: local verification and replay metadata.
- `checksums.sha256`: SHA-256 digest index.
- `verify.mjs`: local verifier for hashes and required schema keys.

## Verify Locally

Run from this directory:

```bash
node verify.mjs
```

Expected result:

```text
Helix sample evidence bundle verification passed.
Verified 5 checksums.
Verified required keys for 4 JSON artifacts.
```
