When she writes in Chinese, say Translate — not Clarity

She reaches for her own language mid-sentence when English won't come, and
Petal already handled it: it found the span and rendered it into English. It
just filed the result as a Clarity fix, so the pair model's flagship moment
read as tidying up her Chinese.

The type is now derived from the span rather than asked of the model. A type is
structural, and a model that re-reasons every pass would drift between labels
for a sentence nobody had touched — the instability the last session spent
itself removing. The label the model volunteers is still ignored.

Only the grammar checkpoint can be promoted. A pass with a forced type owns its
family: voice reads paragraphs for tone and its rows carry no replacement, so a
"translation" there would be a card offering nothing to accept.

zh is a different script and counting Han runes is close to certain. The Latin
pairs share an alphabet with English and get none of that, so they fall back to
function words and need two before Petal claims anything — with every word that
is also English left out, even the common ones. The heuristic is justified by
how cheap being wrong is: it changes a coloured pill, and nothing else.

The pill is the one bilingual type name in the rail. Every other type stays
English because those are the terms she is learning; this card's whole subject
is her own language. And it stops truncating its two lines — elsewhere the diff
is a word and the explanation is what she reads, but here the two sentences are
the card.

Two things only the running page could report. The inline underline was
invisible: the decoration carries a per-type class and the base rule is a
transparent border, so a type with no colour rule gets no mark at all. And at
1517×810 with the document list open there is no rail — the margin is 258 where
railEnabled wants 348 — so what she gets is the inline hover card. Item 7 is
written the other way round.

Migration 0015 rebuilds the suggestions table for the CHECK, which makes it the
first one here that could quietly drop her rows; there is a test that carries
every column, both timestamps and both indexes across it.
