| Internet-Draft | Correctover Conformance Shape (CCS): Run | September 2026 |
| Wang | Expires 18 March 2027 | [Page] |
This document defines the Correctover Conformance Shape (CCS), a runtime verification framework for AI agent tool calls. CCS specifies seven verification dimensions (Structure, Schema, Latency, Cost, Identity, Integrity, Security) that tool calls and results must conform to at runtime. The framework defines a receipt format with Ed25519 signatures, three verdict values (allow, deny, escalate) and four executor lifecycle states (confirmed, dispatched, indeterminate, unknown), and normative requirements for implementations.¶
This revision makes the document self-contained for publication: the related AEB and CAID specifications are reclassified as Informative References, and the native artifact requirements they motivate are restated normatively in this document so that no conformance requirement depends on an unreferenced work in progress. It also corrects the implementation-experience description (one reference implementation in two deployment forms, plus one independently developed third-party interoperability profile), clarifies the relationship to SCITT-based agent evidence work, and updates the author contact address. The detached Ed25519 signature construction over RFC 8785 canonical JSON and the receipt lifecycle and signing-algorithm conformance are unchanged from draft-08.¶
This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.¶
