I18N Integrity

Translation Integrity (i18n)

Trigger phrases: "i18n", "translation", "language file", "missing translation", "localization", "translate", "untranslated", "hardcoded string", "multi language", "multiple languages", "still in english", "locale"

Goal: no missing/broken text in any language. Default languages: TR / EN / DE / RU (the project sets these).

Audit dimensions

• Key parity: every key has a counterpart in ALL languages; a missing/extra key = a finding.
• No hardcoded strings: user-facing text is not embedded in code, it comes from the language file.
• Placeholder consistency: {name}, %s, ICU {count, plural, ...} are identical in every language.
• Plural rules: language-specific plural forms (especially RU) are correct.
• Empty/identical value: an untranslated (identical to the source) placeholder value is flagged.

Check (key-set comparison)

# Example: compare the key sets of JSON language files
for f in locales/*.json; do echo "== $f =="; jq -r 'keys[]' "$f" | sort > "/tmp/$(basename $f).keys"; done
diff /tmp/tr.json.keys /tmp/en.json.keys   # differences = missing/extra keys

DoD

• Key sets are equal across all languages; no hardcoded user text; placeholders are consistent.
• Missing translation = red (no deferral).
