Status

Ratified / implemented at contract level for global-working-memory.

This page records the normalized Slice 2 implementation after reconciliation with the canonical STONE Source Manifest and existing MASON/Observatory roles.

Core law

SOURCE ≠ AUTHORITY ≠ CONFIDENCE ≠ ACCESS.

The Context Provenance Envelope is a portable per-object metadata layer. It does not replace the STONE Source Manifest, does not create a new authority store, and does not bypass STONE → MASON.

Canonical model

• Stable object_id is distinct from immutable envelope_id and source-native source_id.
• Source identity records provider, native ID/URI, native version, observation/retrieval time, and SHA-256 source fingerprint.
• Authority is explicit: authority_domain, authority_owner, authority_state, optional authority_resolution_ref.
• Confidence never upgrades authority.
• Access/write policy is represented by policy references, separate from authority.
• Lineage is a typed DAG using direct parent envelope IDs and relations such as derived_from, copied_from, migrated_from, revision_of, supersedes, extracted_from, merged_from, and generated_from.
• Ordered transformation activities record executor/tool, inputs, policy/config reference, execution ID, timestamp, and output reference.
• Runtime links may include workflow execution_id, retrieval/Observatory trace IDs, span IDs, and MASON receipt IDs.

STONE integration

STONE remains responsible for source-object resolution, reproducible payload boundary, requested transformation, scope, retained/rejected receipts, unresolved conflicts, provenance classes, integrity/replay fields, and its completion gate. Envelope references may be attached as evidence pointers but may not widen a locked STONE boundary.

MASON integration

MASON consumes locked STONE manifests plus referenced envelopes. Governed durable writes/promotions must preserve lineage and record MASON execution receipt IDs. Original provenance classes and unresolved authority conflicts are never silently rewritten.
