Method
HOW A TARGET BECOMES A DOSSIER

No black boxes.
A transparent
ledger of every call.

The engine commits to a grouped, weighted evidence model. Every connector that touched the target, every item that influenced the score, is persisted and printable.

Connect

Fast pass and deep connectors

A generic connector runs first. Platform-specific, identity-graph, reputation-search, and operator-intelligence connectors run deep.

Weigh

Grouped deterministic scoring

Signals map to 9 evidence groups. Corroboration and complaint-source diversity raise score more than repeated single-source signals.

Decide

Floor-aware verdict

Social and marketplace profiles never reach low risk from generic positives alone. Independent positive reputation evidence is required.
