Traceability Chains and Chain-of-Custody Proofs

Track document or multi-document workflows by `chainId` across upload, manifest, and version flows. Use `sort=asc` for operational replay and `cursor` for continuous load-more timelines.

Show not only what was stored, but how it moved through a business process.

Traceability extends permanence into workflow history. It links files, events, and actors into a chain that buyers can use for compliance, provenance, and operational audits.

Value

Build process-level evidence chains

Files become part of a larger business sequence, not isolated records floating without context.

Support provenance-heavy sectors

Supply chain, legal evidence, compliance review, and regulated operations all benefit from linked event history.

Create better downstream automation hooks

Trace events become useful signals for connectors, alerts, and customer-facing workflows.

For operators

• Record chain IDs, steps, and actors so file events remain tied to the process that created them.
• Use Business Profiles when trace events must carry domain-specific metadata that can still be validated.
• Pair with Connectors and SDK helpers for integration into external systems and custom apps.

For buyers

• Strong fit for buyers who need auditability, chain of custody, or provenance they can explain externally.
• Helps the platform feel more like workflow infrastructure than passive storage.
• Adds substance to industry-specific demos, especially in supply chain and legal settings.
