Mobile i18n + Dev Translate

Goal

Ensure all user-facing strings are translatable from day one.

Source of truth notes

• Ratio-scaling guidance remains in mobile/AGENTS.md.
• Keep this skill scoped to i18n/dev-translate; do not duplicate scaling policy here.
• Keep guidance additive and concise; reference canonical policy docs instead of restating them.

QC evidence contract (i18n scope)

• For i18n-related changes, report touched translation/config files and rationale.
• Confirm user-facing strings in touched scope remain translation-driven.
• Report findings with baseline-vs-introduced classification.

Baseline Setup

• Use i18next + react-i18next
• Keep resources under src/lib/i18n/resources/{lang}/
• Initialize in app providers at startup

Language Management

• Store app language in Zustand store
• Expose explicit language switch function
• Use fallback language (en)

Dev Translate

• Enable missing-key diagnostics in development
• Log missing keys with namespace and language
• Keep feature text in keys, never inline literals

Starter Done Criteria

• At least en and pl resources exist
• Home and auth starter screens read strings from i18n
• Missing-key logs are enabled for development mode
