Package committer holds the deterministic checks of the committer role (roles/committer).

Package documentalist holds the deterministic part of the documentalist role (roles/documentalist): which docs became suspect because a source changed, which are only pending because the cascade is cut, the hygiene checks (budgets, duplicates, links, identifiers gone from the code), and the judge of the patches the agent proposes for suspect docs.

Package productowner holds the deterministic steps of the product owner role (roles/product-owner): pre lists the open issues with what the engine knows of each; the acts the agent proposes are checked when the engine applies them (internal/backlog).
