One item was left in Software & PHP — an OS package management UI. The System Updates page only applies updates to packages already installed, so installing something new was a real gap. This adds searching the server’s package index from the panel and installing on demand, queued with the same live terminal-style log System Updates uses.
The interesting design question was how far to let an admin-chosen package name reach. The answer follows the same reasoning as the Database Browser’s query runner: this is an admin-only, high-trust action, so there’s no reason to fence it down to an allowlist of “safe” packages. The privileged side still independently validates the package name and confirms the package exists in the configured repositories before anything installs, rather than trusting the front end.
One deliberate performance call: search does not refresh the package index first, because that would add seconds to every search for no benefit, since the index is already kept current by System Updates and routine automatic updates. Installed-status per result is a fast lookup against the installed list rather than a nested loop.
Live-verified on a development server with a harmless, side-effect-free package: searched, showed as not installed, installed for real with the live log showing the package manager’s output, and searching again correctly showed it installed, proving the status is read live. It was removed afterward.
Software & PHP is now fully Live.
