94c, the last C-mig piece. The #65 enumeratedir-cap gate built a 300-file
bigmod dir (past the old 256 cap) and byte-compared cstage vs wwstage
.combined.ww to prove both enumerate the complete file set. The flip
deletes combined.ww, so the comparison now targets each stage's
<stem>.sepwork/bigmod.unit.ww (one `package bigmod;` clause per enrolled
file). count_pkgs asserts the full nfiles count and `cmp` byte-compares
the two stages' unit, so a silent cap-drop on either side reddens both
paths. >cap fixture unchanged. Test-only; all 5 binary pins HOLD.
The wwstage driver silently dropped directory entries past a 256
cap; the cstage twin already grows by realloc-doubling. Grow the
same way (seed 8, double) so both stages agree on any directory size.
