Record the rc.24 certification: floors 2903/917/2864

Cold cache (116K -> 269M), all three platforms compiling, zero "No tests to
run". The delta was +65 / +14 / +65 and reconciled exactly to a prediction
written down before the run.

Also records a failure mode this page did not have: a corpus suite went red
mid-run because the CORPUS MOVED. Root2JsonCorpusTest failed on reactive-bbq,
and re-running it alone read 190/190 clean -- riddl-models had committed twice
during the certification, one of them converting that very model. Nothing in
riddl changed. The check is one command against the sibling repo's log, and it
is decisive.

Deliberate failures are 190: 189 in commands and 1 in riddlc, the latter being
riddl-examples' dokn failing on exactly 5 set-after-morph errors. Both are
corpus cost from rules that shipped after rc.23, and both are confirmed by
message rather than by count.
