i18n & Localization

Language is culture, not just words.

Core Concepts

• i18n (Enable) vs L10n (Translate).
• Structure: locales/{lang}/{namespace}.json.
• RTL: Plan for right-to-left layout.

🧠 Aletheia Reasoning Protocol (Localization)

1. Generator (Visual Expansion)

• Length: "German is 30% longer. Will the button break?".
• Direction: "Arabic is RTL. Will the sidebar flip?".
• Context: "Is 'Date' a fruit or a meeting?".

2. Verifier (Cultural Audit)

• Colors: "Red means lucky in China, danger in US.".
• Formats: "MM/DD/YYYY vs DD/MM/YYYY".
• Hardcoding: "Grep for raw strings".

3. Reviser (Key Management)

• Hierarchy: "Nest keys by page/feature".
• Plurals: "Use ICU format".

🛡️ Security & Safety Protocol (i18n)

1. XSS: Sanitize translations (No <script>).
2. Interpolation: Prevent injection via variables.
3. Locale Spoofing: Validate locale param against allowlist.
4. Info Leak: Consistent error messages across languages.
