# The picture and the API are the same model. Are they the same ANSWER?
#
# check-editor-parity.sh proves the editor can SAY every constraint the model layer has. That is a
# check on vocabulary, and it passes an editor whose `fromModel` drops a k, a soft price or an
# objective term -- such an editor still draws every node type, still runs, and answers a different
# question. The gap between "can say it" and "means it" is exactly where check-parity.sh and
# check-semantics.sh sit apart for the language bindings, and the editor deserves the same pair.
#
# So: one JSON model at a time, through the HTTP API and through the editor's fromModel, comparing
# the COMPILED size and the feasibility. Not the values -- both surfaces anneal, and two runs of a
# stochastic sampler are entitled to differ. Spins and ancillas are not: they are what the model
# compiled to, and a lost constraint shows there.
#
#   scripts/check-editor-model.sh
#
# --selftest first: this gate reads its numbers out of a report with a regex, and a regex that stops
# matching reports -1 on both sides and calls it agreement.
