Snapshot Format Reference

Snapshots are JSON objects keyed by fact label.

Shape

{
  "fact-label": {
    "samples": [
      {
        "traces": [{ "path": "file.txt" }],
        "content": "hello"
      }
    ],
    "created": "..."
  }
}

Batch fields

• samples ordered list of samples
• created timestamp for when the batch was created

Sample fields

• traces ordered list of trace objects
• content string content being tracked

Stability notes

• Snapshot files are a practical storage format, not a public network protocol.
• They are suitable for inspect, diff, check, apply, and op eval experiments.
