compiler: text keys (phase 26.2) - k"pause.resume" / kn"catch.count" of the builtin type Key (not a string, and no string one; == compares), its run-time value the key after a marker byte (1, or 2 for a plural); package.ludic's lang "assets/lang" en and a gettext .po reader; every key literal checked against en.po (a kn"" one wants a msgid_plural), trf / trn and a template's t('key', ...) against the English's holes, a component's template words and a @Text row's English as "English left" (warnings, english_left in ludic deps), a @Text Key field a compiled row leaves out filled with its derived key <registry>.<row>.<field> (or @TextKey's prefix; maps.<map>.<table>.<row>.<field> for a @PerMap row, checked), one English under several undescribed keys warned at en.po's line; the schema's "lang" (keys and their sites, unused, undescribed, split, and every other language's missing / fuzzy / extra); k"" in .lres data, @PerMap rows included (lres_key); ludic-fmt keeps a key literal whole; reseeded, bootstrap-cfree fixpoint holds
