Documentary boundary

The internal record supplied with the problem consists of excerpts and summaries associated with corpus identifier ca99b12b, retrieval identifier retrieval-3 SuppliedRecord. It explicitly describes a local retrieval rather than a complete scan of the series.

Accordingly, the documentary conclusion below is restricted to the supplied record. Statements about Em02-E, En02-C, En02-D, and XVI-P that are available only as summaries are identified as such. Their full manuscripts have not been independently checked here. An internal label is a source locator, not a theorem proved by this paper.

In particular, “not constructed” and “not admitted” are not replaced by “mathematically nonexistent.” Similarly, “XV-B remains closed” means that its downstream admission condition remains undischarged; it does not mean that a manuscript named XV-B is absent.
