;;; Commentary:

;; Smoke tests for `testutil-fixtures'.  The fixtures exist for the upcoming
;; query/representation tests, which don't exist yet, so without this file the
;; suite would never load the fixtures and a syntax slip or shape change would
;; rot unnoticed.  These assertions exercise the file and lock the key shapes
;; the consuming tests will rely on (json-read conventions: missing keys for
;; absent fields, `t' / `:json-false' booleans).
