Researcher Evidence Record

Alexander Erhard

This bounded record lists 9 Pith paper rows and 0 imported work rows attributed to this corpus identity. The enumerated, non-disputed paper rows include quant-ph work dated 2018 to 2026. 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 9 attributed paper rows in the Pith corpus, itemized below Imported works 0 imported works beyond the paper ledger Current reviews 2 of 9 papers carrying a current Pith review; presence, not outcome Sourced citations 2 of 9 works with a source-named citation count Coauthors 40 distinct coauthors across shared paper rows
Enumerated paper scope: 1 field (quant-ph) · 2018-2026 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.

Evidence apparatus

The machinery behind this record. Every lane states whether Pith measured it, did not query it, could not reach it, or withheld it.

Enumerated research scope

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.
