Replaces the 16/4 MEAN with a per-group measurement, closing the caveat that a
5/5/3/3 split would have made the counter's step-of-four a coincidence.
Route_S02.tbl names routes Route_<squadron>_p<phase><kind>, so the squadron->phase
link is readable off the disc. Stage 02 has 37 phase-1 squadrons; intersecting
with the e010 roster gives exactly FOUR -- ADS151, ADT102, ADT107, ADT113 -- and
every one has n=4, summing to 16 craft.
The five e010 groups NOT in phase 1 (ADN204, ADN206, ADN208, ADN209, ADS251)
include both n=6 groups and the n=9 group. That is why the stage-wide mean
misled: the odd-sized squadrons belong to later phases. Restricted to phase 1 the
size is uniform.
Pure static, no emulator. The hypothesis itself stays 🟡 -- the runtime
kill-one-e010 test is still the thing that would confirm or kill it.
