Optional evidence dump for the FINAL failed attempt, appended to the thrown message.
A bare model-noncompliance: says only "the model didn't do it" — and the fixtures are
purged at teardown, so nothing can be re-queried afterwards to find out WHY. Without this,
"the model declined" is indistinguishable from "the tool was never advertised" or "the
response came back empty", which is precisely how three real product defects hid behind this
prefix during the 6.1 release. Must never throw: a failing diagnostic must not replace the
failure it is describing.
