Detailed Description

One Layer-1 objective, scored on the chamber and engine that are actually drawn.

L1-03 / CN-3: the worker and inline objectives were two implementations that disagreed by
~300 points on one design (worker cone to R_t, clipped at 1 m; config cone to r_tan). Both now
call ``_compute_objective_value``. CN-9: engine length was cone + 0.8 D_exit instead of
face-to-throat + the 80 % Rao bell the contour draws. L1-06, L1-09, L1-10, L1-11 and INJ-7 are
defects in the same scoring function.

Expected numbers come from hand geometry (frustum + entrance arc, H&H ch. 4) and the Rao
contour generator, never from the function under test.
