Evidence Challenge, Appeal and Correction Propagation API

Pre-flight checklist

• This is an API feature request, not a consumer app or Comet UI request.
• Check current documentation and forum topics for closely equivalent functionality before posting.
• The developer workflow or API use case is described below.

Feature type

New endpoint or API capability; New response field or metadata

Affected API area

Agent API; Search API

Summary

Make evidence-record disputes, revisions and downstream correction notices machine-readable.

Problem

A published verification finding may be challenged or corrected after AI systems have already retrieved or cached it. Merely issuing a new webpage is insufficient for traceable downstream updates.

Proposed API behavior

Support challenge submission by eligible parties, acknowledgement, review status, decision reasons, correction versions, supersession and revocation. Offer read-only status endpoints and optional signed event notifications for consumers, with authorization and abuse prevention.

Example usage

A published finding is corrected after fresh institutional evidence. An application requesting the old claim ID receives a superseded status, replacement version and link to the published rationale.

Workarounds tried / considered

Manual errata pages, changed web content and cache expiry provide partial workarounds but do not guarantee a standard appeal lifecycle across consumers.

Impact

Affected individuals, institutions and developers gain clearer remedies, reduced stale citations and auditable correction history.

Additional context

This expands the correction-history principle in my published proposal into a standalone workflow. Design must protect privacy, prevent abusive disputes and avoid revealing confidential appeals.
