Where in the criteria the problem is, as keys and array indices.

`["windows", "some", "name", "startsWith"]` reads as
`windows.some.name.startsWith`, which is what the message renders. Kept
apart from the message so a caller that built the criteria from somewhere
else — a form, a config file, an MCP client — can point at the right field
rather than parse a sentence. Empty when the criteria themselves are not an
object at all.
