The router deliberately scores familiar text as less novel, so every
benchmark run slightly burns the hard-prompt pool — with 3 templates per
test a variant would drift below the high band within a handful of runs
and flip the test red for no real reason.
Two-part fix: pools doubled to 6 interdisciplinary families each (science:
+ quantum error correction, soil-carbon MRV, cryo-EM; ops: + ED triage +
staffing, port berth/tides/rail, agri-drone fleets — all probed high against
the live router), and a route-judged test that lands non-high gets ONE retry
with a freshly generated template before failing. A single burnt wording no
longer fails the assertion; a genuinely unreachable high tier still does.
