Security review follow-ups. The 200-character registry-name cap the UI
forms promise now holds in domain.Validate for categories, tags,
merchants and instruments, so a non-browser client cannot persist an
unbounded name that every subsequent state response would carry. And a
model-supplied merchant or taxonomy name containing control or format
code points — bidi overrides, zero-width characters — is dropped like
an identifier-shaped one: React escaping already prevented injection,
but such names could visually spoof or reorder the review UI the
operator approves from.
