Researcher Evidence Record

R. Gregor

This bounded record lists 32 Pith paper rows and 0 imported work rows attributed to this corpus identity. The enumerated, non-disputed paper rows include nucl-ex, hep-ex work dated 2007 to 2015. The record describes sources and coverage; it makes no judgment about the person.

Compiled coverage vector

Measured lane counts only. Not a trust score or person verdict.

Identity 2 canonical identity row plus typed public identifiers Pith papers 32 attributed paper rows in the Pith corpus, itemized below Imported works 0 imported works beyond the paper ledger Current reviews 0 of 32 papers carrying a current Pith review; presence, not outcome Sourced citations 5 of 32 works with a source-named citation count Coauthors 50 distinct coauthors across shared paper rows
Enumerated paper scope: 2 fields (nucl-ex, hep-ex) · 2007-2015 sources: authors, author_identifiers · paper_authors · author_works · current_verdicts · cited_works

A sourced case file for attributed work. It is neither a profile score nor a verdict about this researcher.

Attributed works

A bounded ledger from the Pith paper and imported-work queries. Counts and source confidence stay with each work.

Record scope

The work queries are bounded. Missing rows may mean measured zero, an unavailable source, a query that did not run, or private data that Pith withheld. The lane table keeps those cases separate.

Paper findings remain attached to papers. They do not become findings about this researcher.
