Everything else a group's library is made of -- the artifact, its dialects, its
chapters, the translations of it -- is signed into existence by a quorum. The
translation of a chunk was the last thing still being saved: `saveTranslation`
wrote the row on this device and queued a submission, and the group's only
recourse afterwards was social.
That is the wrong way round for this one in particular. An artifact is a link
and a name; a translated passage is a claim about what somebody else's words
mean, made in the group's name, and it is what every reader of that translation
reads instead of the original. If anything in the library deserves a quorum it
is this one.
So the screen proposes rather than saves, the way `AddArtifactScreen` does.
Nothing is written when the button is pressed. What goes out is a proposal to
sign a `TranslationChunkEvent`, and the translation appears on every member's
device at once -- authored by the room's own key rather than by whoever typed
it, since signing runs at the path the room was derived at -- when enough
members have signed.
**The form knows whether it can sign before it offers to.**
`TranslateChunkUIState.Loaded` now carries the room and
`frostSigningRepository.canSign`, so the view model has something to propose
with and the button has something to check. Greyed out with
`semantics { disabled() }` when the group holds no shared key, and the screen
says why: a group without one cannot translate here at all, and that is a dead
end to say up front rather than a proposal to be told about afterwards. The
disabled colours are borrowed from `ButtonDefaults` because M3 gives a FAB no
`enabled`, which is what the artifact and dialect forms already do.
**The index is read off the source chunk**, as the DAO did before it. A chapter
is translated a passage at a time and in no particular order, so counting what
is translated so far would number the translations by who got there first.
**Onto the session, not back to the chapter.** The editor is popped and replaced
by the signing screen: nothing has been translated yet, so a table still showing
the passage untranslated would read as a failure. Back from the session lands on
the chapter table, which is deliberately left alone -- the old flow popped and
reloaded it to reflect a save, and there is no longer a save to reflect.
**`ProposedEvent` learns kind 30309.** Without it, members would be asked to put
the group's name to "Event of kind 30309". A translated passage is summarised as
its position and then the translation itself: the words are the whole of what is
being decided -- signing this is agreeing they say what the original said -- and
the position is what tells the reader which passage to weigh them against.
