fix(translation-worker): enforce ±3 word count on short UI copy - #998
Conversation
- Count words on 2–24 word source strings and reject translations outside ±3 - Exempt compact CJK locales; fall back to English like length guard - Tell the model to preserve word count for headings and short UI labels - Bump translation cache version and add parser regression tests Co-authored-by: Martin DONADIEU <martindonadieu@gmail.com>

Your included PR review attempts over the past 7 days set your current allowance at 2 reviews per hour. 📝 WalkthroughWalkthroughThe translation worker now enforces word-count limits for short UI translations. It updates prompt guidance, error handling, source fallback behavior, cache versioning, test helpers, and parser verification coverage. ChangesTranslation word-count enforcement
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The change adds word-count enforcement for short translations and falls back to the English source when a translation is too long. The PR is mergeable with owner awareness that the fallback regression test should explicitly demonstrate this new behavior. Sequence Diagram(s)sequenceDiagram

- Around line 199-200: Update the fallback fixture in guardTranslationLength so
the translation is exactly four words longer than the source while remaining
within the character-length threshold, ensuring the assertion specifically
validates the word-count rule rather than the length check.

Problem
French headlines and short UI copy often translate into many more words than English, breaking layout (nav, hero headings, buttons).
Fix
Add a ±3 word count constraint for short translatable copy (2–24 source words):
translationWordCount()counts Unicode words (handles French elision/apostrophes)Tests
