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: apply the requested transition to new prediction through the authoritative prediction service boundary.

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 new prediction 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: creates or advances only the new prediction resource described by this contract after authorization, validation, policy, and idempotency gates pass.

WHY IT MATTERS

  • Lets people and agents prepare for new prediction without falsely presenting roadmap scope as a live capability.
  • Gives people and agents a contract-backed way to advance new prediction.
  • Separates contract definition, participation, evidence gathering, governance decisions, resolution, publication, and settlement so a planned interface cannot be mistaken for a live market.

ISOLATION + AUTHORITY

Tenant, workspace, prediction contract, participant, market status, order admission, matching, evidence source, reviewer, resolver, governance decision, payout, settlement, and finality remain distinct. These planned contracts grant no ability to create a live market, accept orders, match trades, publish outcomes, resolve funds, or change frozen prediction or trading controls. 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.
  • Treat the proposed title (body), outcomes (body), closes_at (body), oracle_policy (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.

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 new prediction 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 new prediction only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
  • Treat the proposed title (body), outcomes (body), closes_at (body), oracle_policy (body) as planning input only; re-generate the request from deployed OpenAPI before making a call.
  • Distinguish draft contract, admitted market, participation, order state, evidence observation, lifecycle decision, resolution proposal, finalized outcome, payout, and settlement.
  • 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.

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.

UPGRADING FROM V1

Legacy calls replaced by this operation

If you maintain an older integration, use this map to find the V2 replacement. Do not translate the old request field-for-field: rebuild it from the V2 parameters and schemas above because identity, authorization, replay protection, and response semantics may have changed.

POST/api/v1/prediction/createPREDICTION: Create new Prediction
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.
