# Artifact

Immutable data unit

Layer: Infrastructure · Category: Data Structures

## Mechanism

A discrete, immutable unit of data produced by a solver or workflow. It serves as a typed input/output token.

## Invariants

- Immutability: Once minted, the content cannot change.
- Addressability: Must be referenceable by a content-derived hash.

## Failure modes

- Link Rot: The artifact persists conceptually but the storage medium fails.
- Hash Collision: Two different artifacts produce the same ID (theoretical risk).

## Data schema

```json
{
  "type": "object",
  "required": [
    "hash",
    "content_type"
  ],
  "properties": {
    "hash": {
      "type": "string",
      "description": "SHA-256 content hash (Immutable ID)"
    },
    "content_type": {
      "type": "string",
      "description": "MIME type (e.g., application/json, text/markdown)"
    },
    "uri": {
      "type": "string",
      "description": "Storage location (s3://, ipfs://, or memory://)"
    },
    "size_bytes": {
      "type": "integer"
    },
    "metadata": {
      "type": "object",
      "description": "Author, timestamp, tags"
    }
  }
}
```
