# Data race on a shared Go map — Agent PR X-Ray

> Canonical page: https://codevetter.com/xray/go-race-condition

This is an adjudicated synthetic benchmark example, not a claim about an uploaded repository.

## Source

- Corpus: codevetter-public-benchmark/go-race-condition
- Language: Go
- Category: Concurrency
- Evidence state: benchmark_ground_truth

## Finding

- Severity: high
- Title: Concurrent map access is not synchronized
- Summary: Multiple goroutines read and write the same map without a mutex or another synchronization boundary.
- Source anchor: `source.go:14`

## Verification boundary

The static finding is qualified against benchmark ground truth. No exact-current executable test or audience validation is included in this example, so those stages remain unverified.
