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.

No generic CRUD action anywhere: real business - a cross-table order
placement, a payment transition - is what the contract surface has to
carry, and the actions cover only the single-table case that a real
application outgrows immediately.
The transaction is Orm.Transaction(), not the Begin/defer shape that
app/admin/service/sys_role.go and three other files use. That shape
commits a half-written transaction when the body panics, because the
deferred check reads err, which a panic leaves nil.
The payment transition guards concurrency through the update itself -
WHERE status = 'pending' plus RowsAffected - rather than a read followed
by a write.
The tests cover both rollback paths, because they fail differently: a
mid-transaction error returns, a panic unwinds - and the second is what
tells Orm.Transaction() apart from the shape it replaces. The concurrency
test pins the pool to one writer so sqlite's own single-writer semantics
cannot stand in for the guard being tested. The data-scope tests assert
the fail-closed direction too: an unrecognised scope must return no rows
rather than every row.

A reference application for a third-party author: its own module, and a
require list that names go-admin-core and nothing else. The point of the
example is that constraint - an application that reaches for the host
cannot be installed through a module proxy at all, because `go-admin` has
no dot in its first path element and a replace directive is ignored
outside the main module.
Two tables rather than one, because a single-table example proves only
what the generic CRUD actions already proved. The interesting question is
whether the contract surface holds up for business that spans tables.
The table names carry an app_ prefix: "order" is a reserved word, and
Permission() interpolates the table name into raw SQL without quoting.
