PLANNING CONTRACT · NOT CALLABLE

This page describes intended capability and integration boundaries so people and agents can prepare safely. Do not send this request or register it as an executable tool. Wait until the capability registry marks it implemented-contract, then re-fetch the deployed OpenAPI document and build the request from that machine contract.

PURPOSE + BUSINESS CONTEXT

Planned capability: issue a short-lived, subject-bound download ticket for an authorized object version.

WHEN THIS CALL IS USEFUL

Do not call or register this operation as an executable agent tool yet. Use this page to plan the future download ticket workflow; enable it only after the status becomes implemented-contract and the exact operation appears in deployed OpenAPI.

OUTCOME · Planned · Create or advance

What changes

None today: this route is not executable. Its intended behavior is: no executable public ticket issuer exists. The legacy direct download returns content through Core and lacks the required subject-, purpose-, version-, and expiry-bound capability model.

WHY IT MATTERS

Lets people and agents prepare for download ticket without falsely presenting roadmap scope as a live capability.
Gives people and agents a contract-backed way to advance download ticket.
Supports private object discovery and evidence selection while keeping content access, keys, grants, storage topology, and retention authority outside the listing contract.

ISOLATION + AUTHORITY

Tenant, workspace, object, directory, version, content, encryption key, storage location, retention policy, access grant, evidence commitment, and download authority remain distinct. Object discovery or integrity metadata does not reveal protected content, create a grant, authorize decryption, or prove an external business outcome. This planning record grants no runtime authority, and only deployed OpenAPI can define an executable public contract.

BEFORE YOU CALL

First confirm that this operation is marked implemented-contract and exists in the currently deployed OpenAPI document; until then, no production request is valid.
Its capability-registry profile is provisional integration guidance, not an executable request schema.
Authenticate at the documented boundary: bearer+scope.
Treat the proposed object_uuid (path), purpose (body) as planning input only; re-generate the request from deployed OpenAPI before making a call.
Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.
Resolve the authenticated workspace, opaque object identifier, object type, integrity requirement, and any separately authorized content-access or retention workflow.

WHAT TO DO NEXT

Keep this operation disabled in clients, agents, SDKs, and workflow automation while it remains planned-contract.
Use the stated owner, lifecycle, authority boundary, and provisional download ticket profile to prepare requirements and conformance tests without sending a request.
Monitor the capability registry for implemented-contract, then re-fetch deployed OpenAPI and validate its exact security, parameters, schemas, responses, and agent metadata before enabling the integration.

AGENT GUIDANCE

Never call this planned contract, include it in an executable tool registry, or infer runtime availability from this readable page.
Its capability-registry profile is provisional integration guidance, not an executable request schema.
Use download ticket only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Treat the proposed object_uuid (path), purpose (body) as planning input only; re-generate the request from deployed OpenAPI before making a call.
Treat object existence, metadata readiness, directory membership, version, integrity commitment, access grant, decryption, download, retention, and external acceptance as separate lifecycle facts.
After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.
When implementation lands, discard generated requests based on this planning record and rebuild them from the deployed OpenAPI operation.

MACHINE CONTRACT

This operation is a non-executable planning contract. Its capability-registry record defines the intended owner, parameters, responses, and integration boundary until an implemented Rust OpenAPI operation replaces it.

EXTENDED INTEGRATION GUIDANCE

Readable request and response reference

Examples describe the reviewed planning contract and remain non-executable until promoted into OpenAPI.

INTEGRATION DECISION

CALLER ACTION: Do not send this request or register it as an executable agent tool. Use the implemented alternatives linked by the module guide.
RETRY SAFETY: Do not retry on a timer. Re-fetch production OpenAPI and proceed only after this exact operation appears there.
STATE RECONCILIATION: No runtime state exists to reconcile for this planning contract. Continue from owner-scoped vault metadata, data classifications, commitments, retention state, grants, and audit evidence through an implemented operation.
ESCALATE WHEN: Escalate when ownership, grant, retention, classification, or commitment evidence cannot be reconciled without disclosing protected data.

OPERATIONAL NOTES

Security and lifecycle guarantees

The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
Mutations are retry-safe only when the same Idempotency-Key and canonical request body are reused.

DOCUMENTATION STATUS

This planned contract now defines its public parameters, authorization boundary, replay behavior, responses, and authoritative owner. It remains non-executable until its owner adapter and conformance tests are promoted into the Rust gateway.
