Row 5 in 098b58d was byte-identical to row 2 ({i32,i32,i64} fields
{{4,4},{4,4},{8,8}}): same struct, same field table, only label
differed. The row's own comment acknowledged "off from 8→8 (already
aligned)" — i.e., it did not exercise mid-record alignment at all
despite the label "i32_i32_i64_mid_align" and the commit-body
listing "mid-record align step explicit".
Replace with {i16, i64}: after f1 off=2, f2 must align off 2→8
before placing the i64. A missing `off = align(off, fa)` on either
walker (check.c:760 / check.ww:958 / structabisize) would land f2
at off=2 and size to 10 — clearly red. This is the shape the row
was meant to be.
Six distinct shapes after this fix; gate polarity unchanged (GREEN).
