The large number at the top is the score of the vendor's best position in a ranking: the number that orders it on that list. These two scores describe the profile itself and never change a position. Rules: how Vendar ranks.
The collector adds these as its passes come online. Until then they are gaps, not zeros.
- Cross-source consistency
Team size, founding year, address and prices compared across the site, LinkedIn, directories and registries. Arrives with the collector's evidence pass.
- Change history
What changed on the profile and how the score moved per question, with the model version. Arrives with the monthly fast pass.
- Case quality grades
Client specificity, baseline and result, scale, causality and verifiability graded 0 to 3 with quotes. Arrives with ranking model 2026.11 after calibration.
- Measurements and buyer reports
Speed and uptime of delivered sites, visibility of named clients, response time to a quote request, and what buyers report 30 and 90 days after a shortlist.
The same facts, limits and citations are served as JSON. Readiness: candidate_only_with_caveat.
