dbt groups with no contactable owner

This rule flags dbt groups with no owner, or an owner with no email address. It also flags models whose group: names a group the project never declares.

Every model in the group resolves to an owner nobody can contact, so the group records accountability without enabling it. A model pointing at a missing group is worse: it reads as owned and resolves to nobody.

Give every declared group a contactable owner. Add owner: {email: …} to each group. Where a model names a group that does not exist, declare the group or correct the model.

Before:

groups:
  - name: finance
    owner:
      name: Finance analytics

After:

groups:
  - name: finance
    owner:
      name: Finance analytics
      email: finance-data@jaffle.example

Rarely. A group exists to route questions, and a name with no address cannot receive one. A shared team inbox is enough; it need not be a person.

manifest.json alone. Owners' names never appear in our findings; we name the group, and keep the owner in the worklist you receive.
