getAllTools() left outer joins #__resources to #__tool_version and then groups by v.toolname -- the nullable side of the join. Every type 7 standalone resource with no matching tool version lands in a single v.toolname IS NULL group, r.alias is neither grouped nor functionally dependent on it, and the server returns one arbitrarily chosen alias to stand in for all of them. A second degenerate group forms around v.toolname = '' for resources whose alias is empty.

On nanoHUB that surfaced as two entries in /api/tools/listAll that are not tools at all: "mdl" (the alias the server happened to pick out of eight orphaned resources) and "". Sixteen resources in total were being collapsed into those two rows.

Group by the alias that is actually selected, make the join inner so the orphan group cannot form, and skip empty aliases. No published tool is lost -- every affected resource is in published state 0, 2 or 4, and the entries are old tool-information stubs and explicit test records.

It stays silent because ONLY_FULL_GROUP_BY is off on that server; with it on the query would be rejected outright.
