Three defects that only a real MySQL run could show.
The table had no version-local migration. Adding the model to
migrations.Migrate covers databases built from scratch, but every existing
one already has the older versions recorded in sys_migration, so that list
never runs again there. cmd/migrate's post-migration table check caught it:
"迁移后仍缺少表：syb_product_filter". The new version file creates the table
and seeds the same eight rules with FirstOrCreate on the normalized key, so
running both paths against one database cannot duplicate them.
Keyword and NormalizedKeyword were typed text, which MySQL refuses to put in
a key specification without a prefix length (Error 1170), so the unique index
could not be built at all. They are sized 200 now, matching how SYBShop sizes
its own matching key. SQLite accepts text in an index, which is why the whole
test suite passed while the real migration failed.
The 只看启用 filter is removed rather than kept: hiding a disabled structural
rule would conceal the one state on this page that matters most, since a
disabled "#" means roughly 65% of 档口 rows start entering the system again.
Keyword search stays.
Verified against the local MySQL database: migration applies, eight rules
present with traditional Chinese preserved (印花大學T normalizes to 印花大學t),
menu row created under 采采管理.
