Coloured by coverage, never by performance. Every cell opens its contributing records — favourable, adverse and mixed together, affiliations visible. Every cell is clickable — numbers open their contributing records; empty cells open the pilots programme.

The full mix stays visible — showing what didn't work is the credibility move. 4 adverse results are as prominent as the 10 favourable ones.

This workspace never shows: a product ranking, universal efficacy or suitability claim, a recommendation, a validation certificate, hidden adverse evidence, or synthetic adoption presented as traction. Absence of evidence is never converted into a marketing claim. Affiliation flags appear wherever sponsored evidence appears. k=5 throughout.
