atlas-completeness

Use when a built atlas needs to be interrogated for what is MISSING rather than what is wrong - before handing a build to a customer, when reviewing an atlas someone else built, or when preparing the follow-up interview after a first modeling pass. Runs read-only absence checks per point type, as AtlasQL SQL through query_atlas with run_audit and the read tools as the fallback (does this step have a performer, a system, an input, an output, a sequence, a source document; does this person have a position; does this process have steps and an accountable owner; is this system provided by a vendor), then produces an INTERVIEW SCRIPT of the questions that cannot be answered from the graph, grouped by who can answer them. Complements atlas-auditing, which detects violations; this one detects absences. Reports only, never mutates.
