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: list the authenticated account's active Transit RSA public-key identifiers and fingerprints without exposing private keys.

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 transit keys workflow; enable it only after the status becomes implemented-contract and the exact operation appears in deployed OpenAPI.

OUTCOME · Planned · Discover

What changes

None today: this route is not executable. Its intended behavior is: read-only projection; it grants no mutation, settlement, traffic, or authority change.

WHY IT MATTERS

Lets people and agents prepare for transit keys without falsely presenting roadmap scope as a live capability.
Gives people and agents a contract-backed way to discover transit keys.
Provides bounded, nonce-bound physical entropy with a verifiable source envelope while keeping source credentials and private signing material isolated.

ISOLATION + AUTHORITY

Caller authorization, nonce, requested byte count, physical source, source key, signed envelope, consumer conditioning, application randomness model, and downstream cryptographic use remain distinct. A valid source signature proves envelope provenance and integrity, not fitness for every cryptographic protocol or permission to perform a downstream action. 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 capability-registry profile as design guidance only; deployed OpenAPI must define the executable request and response shapes.
Resolve the required assurance and byte count, fetch the current source key, generate a fresh caller nonce, and define the consuming application's conditioning and replay policy.

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 transit keys 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 transit keys only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Treat the capability-registry profile as design guidance only; deployed OpenAPI must define the executable request and response shapes.
Validate source ID, key ID, signature, nonce echo, byte count, encoding, freshness, and replay posture, then apply the consuming application's required conditioning and health policy.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.
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 bounded entropy requests, source identity, assurance level, digests, signatures, and retained verification evidence through an implemented operation.
ESCALATE WHEN: Escalate when source proof, digest, signature, key identity, assurance, or replay state fails verification; never substitute unverified randomness.

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.

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.
