Freeze launch

AUTHENTICATIONBearer token · contracts:governService ownercontract-authority-serviceContract sourceOpenAPISTATUSProduction listed

Purpose and usage

What this endpoint does

Freeze the launch intent so its governed digests can no longer change.

When to use it

Call this when a contract author, authority reviewer, deployment operator, or contract-lifecycle agent needs to apply the documented freeze launch transition after re-reading the current authoritative state so it can move a contract launch through draft, analysis, governance binding, freeze, evidence, and deployment preparation without collapsing those gates.

OUTCOME · Create or advance

What changes

Creates or advances only the freeze launch resource described by this contract after authorization, validation, policy, and idempotency gates pass.

WHY IT MATTERS

Gives people and agents a contract-backed way to advance freeze launch.
Creates an auditable path from editable launch intent to immutable, authority-bound deployment inputs.

ISOLATION + AUTHORITY

Launch owner, workspace, source artifact, analysis, declared authority, governance binding, frozen revision, deployment preparation, target network, and runtime deployment remain distinct. Analysis or preparation does not deploy code, freezing does not approve it, and no contract route grants wallet, publisher, matching, trading, or external-domain authority.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required launch_uuid (path), request (body) exactly as defined by the live contract.
Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.
Resolve the launch owner, current revision, source and configuration commitments, authority analysis, governance binding, and target-network policy.

WHAT TO DO NEXT

Re-read freeze launch using the canonical identifier returned by this operation.
Reconcile an ambiguous response with the same idempotency key before attempting another mutation.
Compare the launch revision, source and configuration commitments, authority analysis, governance binding, and target-network policy before moving to the next contract stage.

AGENT GUIDANCE

Use freeze launch only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required launch_uuid (path), request (body) exactly as defined by the live contract.
Treat draft editing, authority analysis, governance binding, freeze, evidence completion, deployment preparation, deployment, activation, and external effects as separate states.
After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then re-read freeze launch using the canonical identifier returned by this operation.
RETRY SAFETY: Do not repeat a successful mutation merely to confirm it. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Persist returned identifiers, versions, commitments, and receipts. Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.

400The request or required headers are malformed.Request must change · JSON RESPONSE+

{
  "code": "invalid_json",
  "message": "The request or required headers are malformed."
}

INTEGRATION DECISIONinvalid_json

CALLER ACTION: Rebuild the request from the live OpenAPI operation and correct the rejected method, media type, header, parameter, or body field.
RETRY SAFETY: Do not retry the same invalid request. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Compare the submitted values with the documented constraints before another call. Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.
ESCALATE WHEN: Escalate when revision lineage, approvals, artifact hashes, deployment authority, or finality evidence cannot be proven consistently.

{
  "code": "invalid_credentials",
  "message": "The bearer credential is missing or invalid."
}

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Discard the rejected credential, complete the documented authentication or reassertion flow, and rebuild any request signature with fresh timestamps and nonces.
RETRY SAFETY: Retry only with a newly valid credential and fresh replay-protection values. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Assume the outcome is unknown only when the connection failed after transmission; otherwise authentication failed before domain work. Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.
ESCALATE WHEN: Escalate when revision lineage, approvals, artifact hashes, deployment authority, or finality evidence cannot be proven consistently.

}

INTEGRATION DECISIONinsufficient_scope

CALLER ACTION: Verify the exact scope, tenant or workspace membership, owner boundary, step-up purpose, feature policy, and resource eligibility. Never broaden authority automatically.
RETRY SAFETY: Do not retry until the missing authority or policy condition has been deliberately resolved with least privilege.
STATE RECONCILIATION: Confirm the caller and resource resolve to the same authority boundary for contract drafts, immutable revisions, reviews, approvals, launch inputs, and deployment evidence.
ESCALATE WHEN: Escalate when revision lineage, approvals, artifact hashes, deployment authority, or finality evidence cannot be proven consistently.

{
  "code": "contract_not_found",
  "message": "The requested launch does not exist in the caller's workspace."
}

INTEGRATION DECISIONcontract_not_found

CALLER ACTION: Verify the canonical identifier and authenticated owner boundary. A 404 may intentionally conceal a resource outside the caller's authority.
RETRY SAFETY: Do not retry the unchanged identifier repeatedly. Refresh the relevant collection or lookup before choosing another identifier.
STATE RECONCILIATION: Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.
ESCALATE WHEN: Escalate when revision lineage, approvals, artifact hashes, deployment authority, or finality evidence cannot be proven consistently.

INTEGRATION DECISIONcontract_conflict

CALLER ACTION: Stop the mutation sequence and fetch the latest authoritative resource, lifecycle state, version, ETag, reservation, or existing idempotency result.
RETRY SAFETY: Retry only after reconciling the conflict. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.
ESCALATE WHEN: Escalate when revision lineage, approvals, artifact hashes, deployment authority, or finality evidence cannot be proven consistently.

RETRY SAFETY: Do not retry the same invalid request. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions.
STATE RECONCILIATION: Compare the submitted values with the documented constraints before another call. Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.

INTEGRATION DECISIONcontract_registry_unavailable

CALLER ACTION: Preserve the exact request and treat the outcome as uncertain until authoritative state proves whether it committed.
RETRY SAFETY: Reconcile before retrying. For one logical mutation, retain the same Idempotency-Key and byte-equivalent request. Never reuse that key for changed instructions. Use bounded backoff with jitter.
STATE RECONCILIATION: Refresh the draft or launch revision, approval state, artifact commitments, authority assignments, and deployment or rejection receipt before another mutation.
