Seems you refer to this object, http://www.openstreetmap.org/way/341791043/history

When I first looked at the map, it was rendered correctly as building and name; however refreshing the page made it disappear.

So it looks like a glitch in Carto or in the rendering database. Do not immediately recommend tagging changes for such reason.

I have opened in ticket in Carto:
https://github.com/gravitystorm/openstreetmap-carto/issues/2611

Clicking the the history button shows the area affected by a flurry
of large scale edits including by woodpeck_repair, though I can't
associate edits with specific objects on the main page.

The object history has 4 versions, none if the edits is by by woodpeck_repair.

no that should be fine. If an amenity fills a building, the amenity tag can be on the building outline.

That would be a mapping regression, since the school fills the building.
In the specific case it looks like the campus should be mapped.

This is not what the wiki says. It says "Mark the boundary of the school using an Area Area or place a Node Node in the middle of the site" thus it does not exclude having the amenity on the building.
Direct and fuller quote from the wiki page I linked to above ..


     "/How to map/

/Mark the boundary of the school using an //Area <http://wiki.openstreetmap.org/wiki/Elements#Area_.28closed_way.29>////Area <http://wiki.openstreetmap.org/wiki/Area>//or place a //Node <http://wiki.openstreetmap.org/wiki/Node>////Node <http://wiki.openstreetmap.org/wiki/Elements#Node>//in the middle of the site if you are in a hurry (or don't have access to information about the boundary and it is not obvious from aerial imagery). /

/This area should envelop the full grounds of the school including all the buildings, sports facilities and grounds. //For schools with multiple sites the multipolygon <http://wiki.openstreetmap.org/wiki/Multipolygon> relation can be used."

/The playground to the west of the building looks to be part of the school going by its name. And I would think the parking area to the east of the building is also part of the school.

However on the information available to me ... I could not reliably map the extent of the school .. so I would map it as a node only. I think this is not regression but removes an assumption (from the present tagging) that the school is limited to the building alone.
