In ATC, agents claim by profile — not hardcoded AVD names — and restore QEMU snapshots in ~1.5s: atc claim --type phone --api ">=35" --play --snapshot-load logged_in atc exec -- ./gradlew connectedCheck atc free Injects ANDROID_SERIAL + --device and renews the lease every 15s. No more mis-deploys!

No cold-boot thrashing or OOMs: • Warm-affinity queue batches jobs on warm AVDs within a 120s window without starving cold configs • Pre-flight RAM & disk admission checks • Targets emulators by default — your charging USB phone is never hijacked (unless you want it to be :P)

No daemon, no npm deps: • Atomic lock (atc.lock) with <20ms in-memory critical sections — zero subprocesses ever run under the lock • 6-tier session identity across ephemeral subshells • Dead-PID GC & 5s offline grace reclaim orphaned leases automatically

The charging-phone failure mode is the one that actually scares me. Claim by profile plus a lease that expires beats hardcoding AVD names, because the next agent will invent a new name and still find your USB device. Defaulting targets to emulators is the copyable rule.
