# NOTE: this file used to carry `filter_run_excluding(:embedding)` — but no
# example was tagged :embedding, so nothing was ever excluded and the whole
# file ran (and failed) against Couchbase. The basic embedded flows are now
# fixed and expected green; only reverse lookups (finding embedded documents
# through an N1QL query on a foreign key inside the embedded array) remain
# unimplemented, and are tagged :embedded_in_reverse_lookup below (excluded in
# spec_helper).
