Memory apparently ignored by Codex until specifically asked to read it

What version of Codex CLI is running?

codex-cli 0.121.0

Plus

gpt-5.4

What platform is your computer?

Darwin 25.3.0 arm64 arm

Terminal.app

What issue are you seeing?

I have a simple instruction in the memories that Codex itself created:

$ cat ~/.codex/memories/conventional_commits.md 
Preferences for this workspace:
- Use Conventional Commits for git commit titles when amending or creating commits, unless the user asks otherwise.
- Include a `Co-Authored-By: Codex` trailer in commit messages to indicate the commit was written by AI, unless the user asks otherwise.

It never follows it until I specifically ask it to re-read the memory; then it starts following. Seems like the memory file is never read on start.
