PURPOSE + BUSINESS CONTEXT

Set or clear the authenticated member's default wallet environment for one workspace through a signed mutation.

WHEN THIS CALL IS USEFUL

Call this when an identity, compliance, relying-party, or trust agent workflow needs to apply the documented workspace preferences transition after re-reading the current authoritative state so it can make a purpose-limited identity or assurance decision with current policy and lifecycle state.

OUTCOME · Revise and reconcile

What changes

Updates only the allowlisted workspace preferences fields and version accepted by the authoritative owner; it grants no adjacent authority.

WHY IT MATTERS

Gives people and agents a contract-backed way to advance workspace preferences.
Separates subject identity, consent, evidence, provider output, review, issuer credentials, and relying-party acceptance instead of collapsing them into a universal trust score.

ISOLATION + AUTHORITY

Bearer subject, tenant, purpose, policy version, role, issuer, reviewer, provider, and relying-party boundaries remain distinct. The response or transition grants no payment, custody, settlement, publisher, matching, or trading authority and must not expose regulated evidence beyond the live schema.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required workspace_uuid (path), default_wallet_network (body) exactly as defined by the live contract.
Use one Idempotency-Key only for retries of the same byte-equivalent logical mutation.
Resolve the applicable purpose, policy version, consent or role basis, and required assurance before relying on this result.

WHAT TO DO NEXT

Re-read workspace preferences using the canonical identifier returned by this operation.
Reconcile an ambiguous response with the same idempotency key before attempting another mutation.
Use the returned lifecycle state and policy version to choose the next least-privilege trust action; do not infer a missing stage.

AGENT GUIDANCE

Use workspace preferences only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required workspace_uuid (path), default_wallet_network (body) exactly as defined by the live contract.
Treat policy availability, consent, evidence capture, completed checks, review, decision, credential issuance, validity, and relying-party acceptance as separate facts.
After a timeout or conflict, read authoritative state before deciding whether an equivalent retry is safe.

MACHINE CONTRACT

The exact deployed parameters, schemas, responses, security requirements, and Hybrid-Chain agent metadata are authoritative at this operation's production OpenAPI JSON Pointer. The readable tables below add integration guidance; the deployed OpenAPI controls if guidance and the machine contract ever differ.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then re-read workspace preferences 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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.

400The request syntax, required metadata, or JSON body is malformed.Request must change · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}

INTEGRATION DECISIONinvalid_credentials

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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

401Bearer credential is missing, expired, or invalid.Authentication required · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is 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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

404The requested resource does not exist within the authenticated authority boundary.Resource not visible · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}

INTEGRATION DECISIONinvalid_credentials

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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

503The authoritative service or read model is unavailable.Dependency unavailable or outcome uncertain · JSON RESPONSE+

{
  "code": "invalid_credentials",
  "message": "the supplied Hybrid credential is invalid"
}

INTEGRATION DECISIONinvalid_credentials

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 subject, claim or credential version, issuer and reviewer authority, evidence commitment, decision, expiry, and revocation status.
ESCALATE WHEN: Escalate when subject binding, evidence minimization, issuer or reviewer authority, decision lineage, expiry, or revocation cannot be established.

OPERATIONAL NOTES

Security and lifecycle guarantees

Set or clear the authenticated member's default wallet environment for one workspace through a signed mutation. Authoritative owner: identity-service.
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.
The tables and examples are derived from the current gateway source OpenAPI. Re-fetch the deployed OpenAPI before execution; deployment status is shown separately on this page.
Only parameters present in the OpenAPI operation are accepted; undocumented query keys fail closed with HTTP 422.

DOCUMENTATION STATUS

This route is implemented in canonical gateway source and appears in the production OpenAPI snapshot observed 2026-09-11T06:35:11.572Z. Authentication, tenant, feature, venue, and market policy still apply.
