ui-trace, the adb wrapper and its device recorder were loose files under
~/.local, and each Android checkout carried its own copy of the same
emulator boot sequence. This puts them together, with an install script that
symlinks them back so editing the repo is editing what runs.
Two things are new rather than moved. `emu` is the emulator lifecycle --
name, serial, list, up, down -- keyed on the AVD named after the enclosing
checkout, which is the rule that lets several sessions work here at once;
and `adb` now fills in `-s` from that same rule, because with two emulators
attached a bare `adb shell pm list packages` comes back empty rather than
failing, which reads as the app being uninstalled rather than the question
being ambiguous.
`emu up` refuses when the machine has no room. On 2026-08-30 an emulator
started with 2.8 GB available invoked the OOM killer, and what it took was
not the emulator that had just started: it walked the user slice and killed
pipewire, dbus-broker and another session's emulator first.
