Concept-ownership migration ledger

concept-ownership.json assigns every heading in the project-start donor glossary to its intended destination under CUST-ADR-006 accepted-1. This is migration metadata, not a new home for canonical definitions.

source-inventory.json pins the donor commit, path, SHA-256, exact headings, and source line numbers. The baseline is the last repository commit before 2026-08-17 UTC; the glossary itself last changed on 2026-06-21. No definitions are copied into this repository. Git history remains the provenance source after the rename.

Reading the assignments

• own: a source concept moves to and is owned by the named destination.
• import: an upstream owner supplies the concept; migration consumers refer to it rather than copying its definition. Community requires the T12 extension.
• split: one source entry becomes separately owned destinations. Family Or Household becomes Household in itc-org and a separate Family seed.
• retire: no destination, with an explicit rationale. None are currently retired.

The four convenience terms retain that status. Their owners steward resolution guidance; the ledger does not promote them to canonical roots.

The registry's counterparty and family-area values are migration locators, not newly approved model identifiers. Destination repositories choose their permanent identifiers through their own review processes. The general evidence strength label is similarly provisional. additional_required_concepts records the Evidence and strength requirements from ADR-006 that are not source headings.

Validation

Run from this repository:

python3 tools/validate_ownership.py
python3 tools/validate_ownership.py --source-repo ../identity-canon
python3 -m unittest discover -s tools -p 'test_*.py'

After rename, pass ../commerce-canon instead. The second command checks the inventory against the pinned Git blob, independent of current working-tree edits. The first can check assignments offline without the donor checkout.

Validation requires complete source coverage, one mapping per source heading, valid disposition cardinality, registered owners, and no destination concept assigned to different owners. It preserves convenience-term status and validates the Family/Household split structurally. It does not establish semantic equivalence from different names or inspect published canon definitions.

Publication prerequisites

T05 must reconcile Delegation Relationship with existing itc-org section 10.18 Delegation. ADR-006 assigns actor-linking delegation to identity, but the existing organization model already defines bounded delegation of authority. Changing the label alone does not resolve the overlap. Preserve the accepted assignment until the canon review resolves the boundary; if ownership must change, amend the governing decision before publication.

T06 must rewrite the old Evidence Source subtype language in Reputation Signal, Performance Evidence, and Beneficial Ownership Exemption against the new assertion/source distinction. Commerce imports Adjudication Outcome from itc-evid. T11 must remove Evidence ownership from itc-gov.

These are implementation requirements in the existing live workplan, not untracked residuals. The ledger check supplies G2 validation evidence; accepted project completion and proof of zero duplicate published definitions remain separate review gates.
