Artifact Lineage

Settld artifacts are linked by deterministic IDs and hashes.

Core lineage chain

1. Policy decision record
2. Execution binding record
3. Settlement decision/receipt
4. Verification report
5. Closepack export bundle

Common identifiers in flows

• gateId
• decisionId
• settlementReceiptId
• runId

Guarantees

• Each artifact references prior decision context.
• Timeline is append-only; updates emit new events.
• Closepacks include enough material for offline verification.
