Where the Doubt Is Kept
Default frozen comparison: the Art Institute index names Rembrandt van Rijn on 237 records, 228 with plain labels; the National Gallery index names Rembrandt van Rijn on 383 under the selected maker-role rule, 363 with plain labels and 5 labels joining multiple terms. The page compares cataloguing fields, not authorship.

A museum can print Workshop of Rembrandt van Rijn, store a linked agent with Rembrandt's dates, and still have made no claim that the work is by Rembrandt. The useful object is the seam between those fields.
Reading the local record...
Layer one / worked records
Three records to touch.
Open the museum source, then compare the printed label with the linked title, id, role, or prefix that lives beside it. These are the three records the page uses to make its central seam concrete.

Touch a phrase. Watch it stay a phrase.
These are the National Gallery of Art's own attribution and constituent records. The label is one field. The linked name, role, and prefix are other fields. Buttons mark only spans that the declared parser recognizes.

NGA attribution field, then the linked slotsLoading the six anchor records...
Select a phrase span to see the parser's current reading.
The instrument
The catalogue has more than one mouth.
The AIC artwork search exposes phrase hits in artist_display. Its artist_ids and artist_title are separate structured fields. The NGA export separates an object's attribution from objects_constituents.csv rows. This page never collapses those channels into a single authorship verdict.

Search prose is not an agent register.
Use the table to see the AIC search totals, the number of frozen rows, and the same phrase matcher applied locally. The search cap forced an id-partitioned crawl. The agent endpoint is shown beside it because the pseudo-agent record is not a master record in disguise.

NGA recovery / denominator in view
The recovery rate has a shape.
The headline uses the full targeted linked-index comparison for the selected master and maker-role rule. This recovery table is a separate test over 5,329 objects with prefixed artist rows, so its denominator stays visible and is not substituted for the full NGA index.

Layer two / the dismissal answered
Ask the index what it kept.
If the label is only a cloud of words, ask the linked index. Change the museum, linked name, role rule, or stratum. The answer moves because the record has changed, not because the page has invented a scale of certainty.

Further result
One label can carry several kinds of relation.
The compound result keeps the terms side by side. A phrase such as probably after a model by is parsed as a hedge plus a declared production-context phrase. It is not forced into a certainty ladder.

Source vocabulary
Published glossaries describe words, not probabilities.
The sampled glossary language is kept as a vocabulary reference. It gives the parser terms to recognize and gives the reader the source's own distinction between a relation and a degree of doubt. It does not create a certainty ladder.

The instrument's boundary
Ask for the verdict it cannot give.
A living catalogue can change, and a label can be incomplete. This page therefore refuses the seductive answers that are not in the record. The buttons make the refusal operational.

The check
This is the page's own audit surface. It names the recomputed values, the free choices, the refusal path, and the uncertainty that survives the freeze.
