Architecture

Deterministic engines do the scoring at zero marginal cost; language models are spent only on the handful of cases a human is about to look at.

Agent	Tier	Responsibility	Cost
Triage scorer	Deterministic	Rule-based transaction scoring: refund abuse, velocity spikes, POD anomalies, rating manipulation.	₹0
Graph analyst	Deterministic	Union-Find clustering over shared devices, IPs and addresses; reciprocal loop and rating-density weighting.	₹0
Explainer	LLM	Turns the signal set into plain-language evidence for investigators and for the accused party.	per case
Planner	LLM	Proposes graduated remediation, constrained to the action ladder and the precision gate.	per case
Reviewer	LLM	Self-check pass that must agree with the evidence before a hard action is offered.	per case
