android-tier.md carried a warning block telling the reader not to use run:device or deploy-device, and offered a manual sequence instead. Both are wrong now: the tasks are the way in, and the warning would read as a live hazard. It becomes a note about what changed, and the manual sequence stays as the smallest thing that works when you want no script between you and adb. "The identity is declared twice" was the section this file had carried for five phases saying nothing enforced that the two ids agree. It describes the enforcement now, plus what APP_ID means since it stopped being a setting it never was. NOTES.md takes the four measurements: that the uninstall existed only to cover a missing -r (which is what makes deleting it a fix rather than a trade), that the emulator tasks installed on a phone, what reading the id back costs, and the boot-wait race filed as #162.
