app-order registered its migrations and its menus and nothing else, so
`migrate install order` answered that no application in the binary registers a
manifest. Which was true, and made the installer untestable against the one
application this repository ships.
The manifest goes in the migration package rather than one of its own because
that is the package a host has to import for the application to exist at all -
its migrations register from there too. A second package would be a second
thing to remember to import, and forgetting it would leave an application
whose migrations run and which no installer can name.
Its Version is not the migration version and the two move independently:
adding a migration file without renaming the application is normal, and so is
a release that changes no schema. The migration versions decide what runs;
this decides what the installed row says.
go-admin-core moves to v2.8.0, which is where contract/app lives.
sys_menu.sort is `gorm:"size:4"`, which MySQL builds as a tinyint holding
-128..127. Sort: 200 passes every sqlite test - sqlite ignores the width -
and fails on a real install with Error 1264, partway through a migration.
This is the exact incident class checksilent's menu-sort-overflow check
exists to prevent, and it reached a hand-written deliverable anyway: that
check only recognises a SysMenu literal from the host's model packages, so
a seed.MenuSpec is invisible to it. Widening the check is tracked
separately; this is the value it would have caught.

Registration goes through core's package-level facades: SetAppRouters for
the routes, migration.ForApp for the schema, and seed.MenuSpec/ApiSpec
for the menu rows - none of which requires importing the host.
The menu component is spelled apps/order/order/index. The frontend tells
a packaged view from a built-in one by that first segment alone, and
getting it wrong is silent: the page falls back to the not-installed
placeholder while the console names a src/views path that was never going
to exist. The tests assert that prefix, that every Parent reference
closes, and that every ApiCode resolves - the three ways a menu graph is
wrong without anything saying so.
