The share of this author’s assessed papers carrying a ⚑ flag. A concentration is a prompt for expert review — never, on its own, a determination about the person.

Collaborators, sized by shared output and coloured by their own reproducibility (green = high, red = low). Click a node to open their card. A pattern is a prompt for review, never a determination.

How this author’s assessed papers reproduced — the outcome of reproduction attempts, not a judgement of the person. Coverage is partial and grows over time.
