Research direction
The issue does not name source files, tests, or code entry points. Start by tracing GitHub mention handling and cloud task creation, then reproduce with @codex review on a pull request; done means one task is created, it is associated with the source repository, and Stop permanently transitions it to Cancelled.

Summary
Mentioning @codex review on a GitHub PR created multiple duplicate Codex
cloud tasks. Pressing Stop briefly shows a loading state, but the tasks
return to “Working on your task.”
Some task detail pages temporarily showed “Cancelled,” then later reverted
to “Working on your task.”
