OIP Specification

The Specification is the source of truth for the wire format: objects, schemas, lifecycle, the trust model, the API surface, and compatibility requirements.

OIP v1.0 — Public Review Draft. This document defines what to implement. For the conceptual model (why) read the Reference Architecture; for the implementation path (how) read the Developer Guide.

What the Specification covers

Core concepts and the eight-object model (identity, assets, evidence, projections).
The Outcome Manifest and Trust Manifest schemas.
The Outcome Trust Metric — evidence-led, sample-size-aware, with published bands.
Discovery, licensing (free / one-time), verification, and update protocols.
Compatibility with A2A, MCP, SKILL.md, ACP/UCP, and Apple App Intents.

Note: the Specification describes the trust model’s bands, confidence, and evidence components. Exact scoring weights and the DeepSenz extension profile are not part of this public preview.
