September 21, 2026 The duplicate-app mistake behind Ace's release checks

While building Ace, a duplicate app with the same bundle identifier caused a release check to launch a stale build. Voice commands fired twice. The lesson was simple: launch by an explicit path and verify that the running process is the artifact you intended to test.

We documented that incident, along with a speech-recognition failure, in the Ace build record:
