# Do These Violent Delights Have Violent Ends?

## Measuring the Post-Merge Fate of Agentic Code

### First longitudinal empirical study of the post-merge lifecycle of agentic and human code in real-world open source projects.

**182**
public GitHub repositories

**30K+**
agentic commits

**121M+**
lifecycle lines tracked

**12**
maintenance operational intents

**143K+**
security & dependency findings

**1 year**
May 2025 to May 2026

## Finding Highlights:

**46%**
higher corrective maintenance rates than human contributions

**1.51x**
times more high-severity static security findings than human contributions

**Agentic code share**
increases the corrective maintenance burden within projects

**No review rate**
increases the agentic maintenance burden of a project
