Superseded canonical-export diagnostic

This interrupted sweep retains all 22 complete cells (88 validated pairs) measured before profiling the q4 regression. It used two canonical savepoint exports per trial. It is not the final Nexmark matrix and none of its cells is selected into the final aggregates. The entire cohort is superseded by the uniform configured checkpoint / draining native-savepoint protocol documented in the connector page.

The corresponding CPU, wall, GC and kernel-wait evidence is retained in the diagnostic directory. All warmups, unfavorable observations, plans and metadata remain available here.
