Artifact

Immutable data unit

Definition

Mechanism

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

Invariants

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

Risks

Failure modes

  1. Link Rot

    The artifact persists conceptually but the storage medium fails.

  2. Hash Collision

    Two different artifacts produce the same ID (theoretical risk).

Relationships

Root pattern: builds on nothing in this library.
