A third product class, almost entirely unrouted
On this page11
Every property in this library describes a shelf as containers and closures
Which is accurate as far as it goes and it is not the whole catalog. The component kind field takes three values, not two.
Across 2,150 products the split is 1,172, 899 and 79
Containers, closures and accessories. The three sum to the whole catalog, so there is no fourth class and no unclassified remainder.
And only three of the seventy nine accessories appear in any use case group
Not three on this shelf. Three in the whole routing layer. So 76 products exist in the catalog attached to no use case at all.
None of the seventy nine is on this shelf
This group draws 253 containers and 289 closures and nothing else, which is true of every shelf described in this library.
Which is a measurable fact about the routing rather than about the catalog
The accessories exist, they are classified, and the use case layer almost never points at them. That is a gap with a known size and a known cause.
And it is the kind of absence a curated shelf cannot show you
Every property here says that a shelf cannot display what it excluded. This is the clearest instance: an entire product class, 79 rows, invisible from every shelf in the library.
It also sets a limit on what any of these properties can say
A page that says the shelf has no vented container, or no fiber desiccant, or no dispensing part, is describing 253 rows out of 2,150. The accessory class is where several of those answers would live.
So the honest formulation is about the shelf and not about supply
Which is how the pages are written throughout, and this finding is the reason that formulation matters rather than a stylistic preference.
Nothing on this page says what the 79 accessories are
They are not on this shelf and the pages describe what is. Naming them would be describing products this property has not measured.
And nothing here says the routing is wrong
Seventy six unrouted accessories may be a deliberate decision or an unfinished one. The record shows the count and not the reason, so the page reports the count.
