Agreed, and the near-miss report is gone.  The series is posted again:

The check is now a fixed list of the 51 keys a json object under arch/ may
carry: 47 of them jevents.py reads, one more metric.py reads, and three are
read by nothing although the tables hold them (Counter, CountersNumFixed,
CountersNumGeneric).  A key outside that list is reported with the object
that carries it.  There is no cut-off, no similarity and nothing that
depends on what a run of the generator happened to read, so there is no
edge case left to work around.

It still runs as "make check-jevents" and as a perf test rather than as part
of the build, and on the tree today it reports exactly the two misspellings
we have, the 16 in this file and 3 in the AMD tables, so it wants those
fixes in front of it or together with it.

The one thing I did not do is put the list in a json schema file, because
perf's build would then require jsonschema, which it does not use today and
which is not in every builder's python.  The list holds the same names that
a schema with "additionalProperties": false would say.  If you would rather
have the schema file and take the dependency, it is a small change from
here.
