beezm a59e52fcbc chat2/10: frag_4 seed gallery — render-only, the 09 setting frozen across 2 anchors + 6 fresh seeds at 8192
FragGalleryTool pins every frag_4 value explicitly (amp 0.5, freq 12, window 0.66 +- 0.18,
zero-mean, stretch 2 with band 0.70/0.05 and the sinker stretched, speck revert 2.5e-7, offshore
and shelf off, labeling on) and proves it is the 09 setting: at 4096 the frozen field is
bit-identical to the 09 frag_4 dump on both anchors (a9, 16.8 M cells each), the frag-off field
to the 08 stretch_3 dump (a8), the interior locked against it (r), ids deterministic (o), the
curve untouched (a1). No generation code changed.

Eight seeds at 8192 - the anchors 1063685222 and 999999937 plus 20260822, 31415926, 27182818,
16180339, 14142135, 17320508 (constants chosen before any render) - each with grayscale, .f32,
relief and the labeled-regions overlay, and the hemisphere-split count/size table with a stated
numeric read rule (too solid < 12 big islands across both hemispheres; shredded if big < 25 % of
all; else good spread). Seven read good spread; 14142135 trips the ratio rule (17 big of 69) and
is the most solid mainland of the eight (99.3 % of land). Graduation held.
