The agent, OpenAI Codex, was tasked with hardening bounds checks for UTF-8 reads in Chronicle-Bytes. It added offset and length validation to RandomDataInput.readUtf8 and readUtf8Limited across three files, and documented readUtf8Limited for untrusted data. The mvn -q verify run failed: command not found. The change merged after 2.69 hours with no change requests.
