The span check compared multisets, so a translation was refused whenever its
set of protected spans differed from the source's in either direction. But
`PROTECTED` ends in two very low-precision alternatives, `\d+(?:[.,]\d+)*` and
the bare markup characters, which claim every digit run and every parenthesis.
Over-claiming is right when masking, because nothing may leak to the engine
unprotected. As a comparison basis it is wrong: the translation is another
language whose ordinary prose trips those same rules, and a gained parenthesis
destroys nothing the source carried. The module's own contract says "whether a
translation broke something its source carried", which is a subset relation.
So the loss half keeps the name and the surplus half gets its own. `added_spans`
refuses only a surplus whose presence is itself damage: an injected `%s` that
`msgfmt` rejects, a decoder artefact like `♪`, a leaked `<unk>`, an invented
`{placeholder}`. Measured over representative shapes, all four of those stay
refused, a gained parenthesis stays refused through the existing `structure`
check, and what becomes admitted is a surplus numeral or an abbreviation like
the Danish `f.eks`.
The gate moves in the same commit, and it has to. fe80a23725 introduced one
predicate for both ends precisely because a writer and a gate that disagree
never converge: the run writes, the gate condemns, `i18n-prune` empties, the
next run writes the same entries back. That commit did not quite finish the job
- `test_i18n_catalogs.py` still duplicates the comparison rather than calling
the shared predicate - so the duplicate is mirrored here. Making it call
`reason()` outright would be better and is left for its own change.
No catalog entry changes here. The refusal markers are all still in place, so
the entries this releases stay empty until a translate run fills them.
