What issue are you seeing?

Every restart prints Session renamed to {NL rename of session}
The UUID does not change.

What steps can reproduce the bug?

Restart codex session.

What is the expected behavior?

resume silently because the name did not change

Additional information

session_index.jsonl appends another identical UUID/name entry on each resume

Start by reproducing the report in Codex CLI 0.147.0 by resuming a named session repeatedly and observing the session-status output. Trace the session-resume and rename-message entry points, then verify that unchanged names no longer print “Session renamed” while actual name changes still do.
