Installer
The first-party mamenein/filament-installer (≥0.3) is a first-run web installer for the Qcentic Edge stack on stateless hosts — Magic Containers, ephemeral disks, multi-replica. With INSTALLER_ENABLED=true and no setup yet, every web request redirects to /install. There is no shell and no local file to flip; the gates live in the database and in env.
What it does
GET /install shows an env checklist; POST /install runs migrate → configured seeders → optional first user, then writes a row to installer_locks. That DB lock is shared across every replica, so two pods finishing at once is safe. The complete page then asks the operator to set INSTALLER_ENABLED=false, redeploy, and press Check — the env retire gate that opens the app for good. Until the lock exists, the plugin forces session.driver=cookie and cache.default=array so SESSION_DRIVER=database / CACHE_STORE=database do not 500 on missing tables.
On the template
The installer ships in the published template/ packages (it is not a Docs stack plugin), so every clone is installable out of the box. Host apps that use Spatie/Shield must wire installer.seeders and listen for InstallerUserCreated to assign the first user super_admin.
