Detect rings the moment they form.

Three engines that usually live in three systems - streaming, graph, rule evaluation - composed on one substrate. Zero replication lag between them.

three engines you usually need
01
Streaming

React to every write the instant it lands. /watch over the transaction prefix is a one-line subscription.

02
Graph

Find rings, detect collusion. PageRank ranks influence; triangle enumeration finds 3-clique mules.

03
Rules

SQL predicates over customer + transaction tables. Predicate pushdown keeps rule evaluation fast.

why one substrate matters

Fraudsters exploit the gap between systems.

Split the stack into Kafka + Neo4j + Postgres and your graph view is 30 seconds to 5 minutes behind reality. A ring spinning up in that window is invisible to the detector that has the right algorithm.

WAL-native /watch + graph queries against the same store means zero lag. The detector and the data are the same surface.
