PURPOSE + BUSINESS CONTEXT

Return proposal state, authority, approvals, and retained evidence.

WHEN THIS CALL IS USEFUL

Call this when a workspace governor, policy administrator, custody participant, or governance agent needs to inspect one specific proposal before presenting it or making a dependent decision so it can make a proposal, authority, decision, or ceremony transition under the correct quorum and policy.

OUTCOME · Inspect

What changes

Read-only projection; it grants no mutation, settlement, traffic, or authority change.

WHY IT MATTERS

Gives people and agents a contract-backed way to inspect proposal.
Keeps deliberation, approval evidence, authority assignment, and threshold-signing participation explicit and auditable.

ISOLATION + AUTHORITY

Tenant, workspace, proposal, voter, authority assignment, quorum, custody participant, and signing-session boundaries remain separate. A proposal, recorded decision, assigned role, or ceremony request does not by itself activate a contract, produce a threshold signature, move value, or grant publisher, matching, or trading authority.

BEFORE YOU CALL

Authenticate at the documented boundary: bearer+scope.
Supply the required proposal_uuid (path) exactly as defined by the live contract.
Resolve the current proposal or assignment version, eligible authority, quorum rule, and purpose-bound policy before relying on this result.

WHAT TO DO NEXT

Re-read the proposal, assignment, quorum, or ceremony state and verify its version and commitments before advancing the governed action.
Refresh proposal when its observation time, version, or lifecycle state is no longer adequate for the decision.

AGENT GUIDANCE

Use proposal only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
Supply the required proposal_uuid (path) exactly as defined by the live contract.
Keep proposal creation, review, decision recording, quorum satisfaction, authority assignment, ceremony request, participant signing, execution, and finality as separate lifecycle facts.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.

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 the proposal, assignment, quorum, or ceremony state and verify its version and commitments before advancing the governed action.
RETRY SAFETY: Repeat only when the integration needs a fresher authoritative projection.
STATE RECONCILIATION: Use returned identifiers and versions as the comparison point for later reads. Refresh the proposal, approval threshold, signer set, policy version, and execution or rejection receipt before changing or resubmitting governance instructions.

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. Do not replay an expired signature.
STATE RECONCILIATION: Authentication failed before an authoritative read was returned for workspace governance proposals, approvals, signing handoffs, policy versions, and execution evidence.
ESCALATE WHEN: Escalate when signer eligibility, threshold evidence, proposal version, or downstream execution state remains inconsistent after a fresh governance read.

403The principal lacks the required scope, role, tenant, or step-up authority.Authority or policy denied · JSON RESPONSE+

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

INTEGRATION DECISIONinvalid_credentials

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 workspace governance proposals, approvals, signing handoffs, policy versions, and execution evidence.
ESCALATE WHEN: Escalate when signer eligibility, threshold evidence, proposal version, or downstream execution state remains inconsistent after a fresh governance read.

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 proposal, approval threshold, signer set, policy version, and execution or rejection receipt before changing or resubmitting governance instructions.
ESCALATE WHEN: Escalate when signer eligibility, threshold evidence, proposal version, or downstream execution state remains inconsistent after a fresh governance read.

INTEGRATION DECISIONinvalid_credentials

CALLER ACTION: Treat the failure as transient and preserve the last known good representation without presenting it as fresh.
RETRY SAFETY: Retry with bounded exponential backoff and jitter; stop after the integration's failure budget is exhausted.
STATE RECONCILIATION: Refresh the proposal, approval threshold, signer set, policy version, and execution or rejection receipt before changing or resubmitting governance instructions.
ESCALATE WHEN: Escalate when signer eligibility, threshold evidence, proposal version, or downstream execution state remains inconsistent after a fresh governance read.

OPERATIONAL NOTES

Security and lifecycle guarantees

Return proposal state, authority, approvals, and retained evidence. Authoritative owner: governance-service.
The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
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.
