 - Pull and capture outputs are additive: the destination must not already
  exist. Re-running a completed pull refuses the existing directory instead
  of overwriting evidence.
- Cancellation during a package pull preserves caller-selected output. The
-  error includes partial observations identifying completed artifacts and the
-  interrupted local path; remaining APKs were not attempted.
- Failed package acquisition rollback retains its directory identity and retries
-  cleanup before later work and during shutdown. Cleanup refuses a replacement
-  directory. Terminal shutdown stops admission and drains active operations.
 - The provider holds no long-lived processes; every invocation is one
  bounded adb run. The adb server belongs to the caller.
