MIME type (upload flow only; null for CID-flow rows)

created_at: DateTime<Utc>

Upload timestamp

entry_count: Option<i64>

Top-level JSON entry count; null when not parsed

filename: Option<String>

Original filename (upload flow only; null for CID-flow rows)

id: Uuid

Unique artifact identifier

line_count: Option<i64>

Line count for text-based artifacts; null for binary

output_cid: Option<String>

Operator-pinned CIDv1 base32 sha2-256 (gh #254 PR2; non-custodial CID-flow rows only — null for upload-flow rows).

size_bytes: Option<i64>
