Generic content-addressed artifact.

This is the common substrate object for records and files that are not only papers: trial registry snapshots, protocols, supplements, notebooks, tables, figures, model outputs, lab files, and dataset manifests. Typed objects such as Dataset and CodeArtifact still exist because they carry stronger domain-specific fields. Artifact gives every byte or pointer the same minimum durability contract.

Fields

id: String

va_<16hex>, content-addressed over kind, name, hash, source, and locator.

kind: String

One of VALID_ARTIFACT_KINDS.

name: String

Human-readable label.

content_hash: String

SHA-256 commitment. Convention: sha256:<64hex>.

size_bytes: Option<u64>

Byte count when known.

media_type: Option<String>

MIME type or close equivalent.

storage_mode: String

local_blob, local_file, remote, or pointer.

locator: Option<String>

Local relative path, file path, HTTPS URL, S3 URL, or registry locator.

source_url: Option<String>

Original upstream URL or accession, distinct from a mirrored blob path.

license: Option<String>

License identifier, URL, or access terms note.

target_findings: Vec<String>

Findings this artifact directly bears on.

source_id: Option<String>

Pointer to the source record that described this artifact, if one already exists in sources.

provenance: Provenance

Artifact-level provenance. The source record may be a registry, repository, dataset portal, protocol page, or paper.

metadata: BTreeMap<String, Value>

Structured adapter metadata such as NCT id, outcomes, accession ids, version tags, or retrieval timestamps.

review_state: Option<ReviewState>

Review lifecycle for the artifact itself.

retracted: bool

access_tier: AccessTier

created: String

RFC 3339 creation timestamp.
