# storm — diamond recursion CWE-407 scan: CLEAN

## Scan date: 2026-03-29

## Method scanned

Storm topology construction and validation: `TopologyBuilder`, `StormTopology`,
worker task routing code.

## Finding

Storm topology validation does not perform recursive graph traversal. Topology
structure is built once via `TopologyBuilder.createTopology()` which iterates
components linearly. No recursive cycle-detection or parent-ancestor walk was found
that lacks a visited set.

The existing `storm-0001` (Fields duplicate check linear scan) and `storm-0002`
(WorkerState localTaskIds list membership) were already filed. No new diamond
recursion patterns were found.

## Verdict: CLEAN
