Recorded readings
The NEXUS matrix records textual states. A match at a site does not itself identify a copying direction.
Recorded + reconstructed history / identity
One text.
More than one parent.
The Caxton second edition carries a base-text relation to Cx1 and an attributed correction source from a second, unresolved exemplar. The graph must preserve both without pretending that shared words reveal ancestry.
01 / Bounded result
A real contamination pattern, with honest limits
The source corpus has 58 witnesses and 4032 NEXUS characters. This interface displays seven witnesses and two source-discussed readings to explain the result, not to substitute a miniature corpus for the full one.
02 / Attributed transmission
Cx2 cannot be represented by one clean tree edge
Every arrow below is attributed to Robinson's published analysis, not observed directly. Solid slate arrows are tree-compatible within this bounded view; the orange dashed correction source is explicitly not.

03 / Recorded reading slice
Same words are evidence, not a family tree
The two sites are deliberately selection-biased examples from the published discussion. “Not supplied” means the compact source projection contains no count for that cell; it is not zero.
04 / Published correction profile
What the number 207 actually says
Robinson reports 207 differences between Cx2 and Cx1 where the Cx2 reading also appears in more than three witnesses. This supports extensive correction from a second exemplar in the published analysis. It is neither 207 copied events nor a Historical Load value.

07 / History equivalence
“Same” is always regime-relative
Pn and Wy can share both displayed readings, the published group, and the bounded transmission role while remaining distinct witness records.

Derived comparison
Exact equality over the selected slice is deterministic but knowingly non-representative.
Attributed relation
Copying and correction-source relations come from the published analysis and remain non-observed.
Unresolved exemplar
The better copy is not given an invented shelfmark, extant witness identity, or false precision.
