728 -> test/asm/matchdispatch_test.ww. The distinct-CMPQ-tag
collection window over TEXT b.next preserved on both stages.
Strengthened: per-row byte-id legs added -- the C header claimed a
cmp -s its code never ran; all three rows verify green.
719/724/744/746 -> test/asm/dataemit_test.ww. Exact DATAW payload
needles, the produce-window zero-init and MOVQ-load count floors,
and the strdef inline-pair want/anti windows preserved with their
per-row byte-id legs.
720/723/727/743 -> test/asm/callarg_test.ww. Ordered PUSHQ windows,
tag-synth + stack-overflow-cleanup needles and the variadic
eightbyte store-count floors preserved. Strengthened: 720's
4-variant row gains the byte-id leg the C skipped behind the
then-open #22 zero-init gate — #22 landed (724 pins the fix), and
the leg verifies green on both stages.
718/721/730 -> test/asm/sret_test.ww. Frame-size and max--K(BP)
stomp sentinels, line-adjacency sret triangle (hidden-RDI, return-
the-pointer, no-AX-capture, forwarding reload) and narrow-trailing-
field windows preserved, including 718's #15 byte-id gate on the
three-return row. 718's whole-suite ww_ww-executable gate dropped
with the other skip gates (the Make target declares the tools).
726/731/732/733/734/735/745/747 -> test/asm/modshadow_test.ww, one
@test per carrier, every want/anti window, occurrence floor and
byte-id leg preserved. New ASM_WW_TESTS block runs the test/asm
observers under test-compiler beside the residual carriers.
