Handoff Package

A handoff_package gives another system enough artifact facts to continue work without losing identity, provenance, policy, or evidence boundaries.

Package contents

A package SHOULD include selected artifact envelopes, versions, parts, byte refs, source links, export manifests, policy refs, evidence refs, integrity summary, receiver constraints, and omitted payload reasons.

Rule

Handoff should preserve refs before copying bytes. If a receiver cannot access private byte refs, the package should say why and include safe previews or redacted substitutes when permitted.
