The tail rescale shipped in cd392e7 is a measured NULL as a search
intervention -- 12 of 12 pairs byte-identical on harbor and maple, 8000 evals
from a plateau, not merely underpowered. Of course it is: the whole failing
tail is 0.034% of corpus value. Looking at the rest of the factor, prompted by
the owner, found something much larger above the threshold.
crink = area_outside/area = (L*h)/A, so 1/crink = A/(L*h) is the room's mean
depth from its daylit wall in storey-heights. That is the right variable for a
daylight rule, and the fail boundary it implies (1/crink = 1.62, i.e. 4.86 m at
h=3) is a sensible one that agrees with 38.3's frontage bound derived
independently. What is wrong is hanging a TWO-sided gaussian on it:
* The near side penalises a room for having MORE daylit wall than target --
while leaf_cost's siblings edge_cost and outside_edge_cost already charge
that same wall at exterior_wall=100 and boundary_wall=133.3 per m2. The wall
is billed once in cost and again as lost value.
* It never earns its keep as a failure either: the over-exposed branch only
reaches FAIL_THRESHOLD above crinkliness 21.5, and the corpus maximum is
3.95. It has never produced a single fail; it only removes value.
* 133 of the 318 passing graded leaves in the 500k baseline (42%) sit on that
side, mean quality 0.810.
crinkliness_shape="daylight" (default OFF, "gaussian" is stock) clips it: a
room shallower than the gaussian's peak scores 1.0, because daylight is a
sufficiency requirement and surplus is the cost model's business, not this
factor's. Clipping at the PEAK rather than at FAIL_THRESHOLD is deliberate --
it keeps the factor continuous and preserves the graded approach to the
daylight limit, where clipping at the threshold would put a 10x cliff on the
exact boundary the 0.5**n fail multiplier already steps on.
Fail set byte-identical on all 21 corpus artefacts for all four
shape/tail combinations, so stock stays a valid yardstick for every arm.
Area-weighted crinkliness quality 0.480 -> 0.513, leaf quality product
0.2722 -> 0.2831; per-artefact score +0.2%..+19.6%, and unlike the ramp it
reaches health-centre and programme-house, where the tail change was 0.000%.
Note "daylight" clips the OPPOSITE side from 38.1's superseded compact_ok,
which forgives being buried; composing either with those modes is refused.
ab_9gj_ramp.py becomes ab_9gj_crinkliness.py and takes named arms, since it
now covers both changes; its first arm is the baseline and the yardstick.
