CHAPTER 06
Data Vault: Protected Information with Verifiable Evidence
Connect confidentiality, integrity evidence, retention context, and governed access around protected business information.
- Private content
- Access control
- Integrity evidence
A protected file is useful only if the organization can also manage its relationship to people and processes. Who may inspect it? What evidence supports its integrity? What retention obligations apply? Can an authorized party retrieve it when required? Data Vault brings these questions into one product context while preserving the distinction between information, its metadata, and the authority to use it.
Confidential content, useful records
Data Vault's public product model combines protected information with distributed storage and evidence about the retained object. Authorized metadata views can help a user identify a record and inspect its available state without exposing decryption material or publishing the contents. Public evidence can provide an integrity reference while leaving the associated business record private.
That distinction matters in collaboration. A team may need to show that a document corresponds to a particular reference while giving the document itself only to an authorized reviewer. The reference and the access grant serve different purposes. Possessing one must not be interpreted as possessing the other.
Proofs with a specific meaning
Integrity evidence helps determine whether the information being checked matches the relevant commitment or retained reference. Retention and continuity information can describe the observed state of a protected record over its lifecycle, where the deployment exposes those capabilities. Such evidence is useful precisely because its meaning can be stated narrowly.
An integrity match does not establish that the document's assertions are true. A retained event is not, on its own, proof that an authorized user can recover the content now. A retention policy describes an obligation or intended behavior; it should be distinguished from observed evidence of that behavior. Public proof descriptions should identify the subject and scope of the check without exposing proprietary proof construction.
FROM ARCHITECTURE TO INTERFACE
Engineering references
The object interfaces give engineers a concrete view of permitted metadata and evidence while maintaining the content-access boundary.
Discover protected objects
Start with the objects visible in the caller's authorized workspace.
GET/api/v2/data-vault/objects- Observable result
- Minimized metadata for top-level protected objects.
- Authority and limits
- Discovery is not permission to download, decrypt, publish, or share their contents.
Inspect object metadata and evidence
Make the distinction between a private record and its permitted evidence concrete.
GET/api/v2/data-vault/objects/{object_uuid}- Observable result
- The owner-scoped object's minimized metadata and commitment-oriented evidence.
- Authority and limits
- A returned commitment is neither the file nor a decryption key, access grant, or recovery guarantee.
Follow an authorized directory
Navigate protected information using the documented resource boundary.
GET/api/v2/data-vault/objects/{object_uuid}/children- Observable result
- Minimized metadata for the authorized directory's immediate children.
- Authority and limits
- This is bounded metadata traversal, not an unrestricted recursive export.
Selected operations were checked against the public OpenAPI contract on October 1, 2026. Links open documentation; they do not invoke an operation. Authentication, exact schemas, and deployment requirements remain defined by the current contract.
Lifecycle responsibilities
Storage evaluation should name the owners of access, key custody, retention, and recovery. These responsibilities remain relevant even when an interface makes the normal workflow simple. The organization should know which authorized workflow retrieves information and how the outcome of an agreed recovery exercise is recorded.
The published object-read interface provides minimized metadata and commitment-oriented evidence. It should not be read as a promise that download, sharing, version management, retention changes, or erasure are enabled through the same interface. Those lifecycle capabilities require their own confirmed contracts and authority. Likewise, withdrawing future access cannot undo information a recipient has already obtained.
Follow the information through its lifecycle
Consider a finance team retaining a confidential supplier assessment. The team first identifies the information owner, intended reviewers, business purpose, and retention requirement. Protection and storage then create a record whose permitted metadata can be inspected. The published read interface exposes a view of that record; it does not replace the separately authorized workflow needed to retrieve the underlying assessment.
| Lifecycle question | Responsibility to establish | Evidence to inspect |
|---|---|---|
| What was protected? | Identify the intended content and version through the authorized workflow. | The exact object reference and the commitment scheme actually used. |
| Who may use it? | Define metadata visibility, content access, and any onward sharing separately. | The effective access decision for the intended reviewer and purpose. |
| What must be retained? | Assign the retention requirement, responsible owner, and permitted review process. | Available policy and observed retention information, without assuming a read exposes either. |
| Can it be retrieved? | Confirm the authorized client, required key custody, and retrieval procedure. | An observed retrieval and applicable integrity check for the selected record. |
| What happens at end of life? | Confirm the supported withdrawal, retention-change, or disposal process and its scope. | The action and outcome actually recorded, with unresolved copies or obligations kept explicit. |
The stages describe responsibilities for an evaluation, not a promise of lifecycle endpoints beyond the published contract. A team can use them to discover missing operational agreements before relying on the stored information in an approval, investigation, or agent-assisted workflow.
Retention evidence and recoverability
A retention requirement says what should remain available for an agreed period. An observation says what was seen at a particular time. A successful retrieval says that an authorized participant obtained the selected content under the tested conditions. These statements are related, but none should silently stand in for the others. A public commitment can remain inspectable even when a required retrieval dependency has not been demonstrated.
For the supplier assessment, an integrity exercise starts with the exact reference and documented verification scheme. An encrypted content root is not automatically a plaintext-file hash. Record which representation was compared and who performed the authorized check. If the retrieval route or required key access is missing, report retrieval as untested or unavailable rather than describing the successful metadata read as a recovery result.
Sharing and end-of-life boundaries
A reviewer may need the assessment itself, while a partner needs only an approved summary and another party needs a narrow integrity reference. Establish those audiences independently. Publishing reviewed context through Agentic Memory Exchange does not turn the source assessment into a public document; it introduces a separate publication decision with its own audience and permitted use.
Withdrawing access changes an access boundary. It cannot recall a copy already obtained by an authorized recipient. Similarly, removing a visible index entry is not proof of physical erasure, and deleting one protected object does not establish the deletion of every related copy. Confirm the supported end-of-life behavior, responsible parties, and retained evidence for the actual deployment. These are acceptance questions, not claims that the metadata interface supplies universal deletion or retention controls.
This lifecycle perspective makes protected information more useful to the business. A team can connect the record to a review or investigation while explaining what was retained, what was checked, and what authority was needed, without publishing confidential content or the proprietary construction of its proofs.
A foundation for connected workflows
Protected records can support compliance review, operational investigations, contract workflows, and selected agent context. The benefit is not that all data becomes available to every connected application. It is that each workflow can use the information and evidence appropriate to its purpose, with the content's protection and access responsibilities remaining explicit.
