i18n Rules

Shared JSON Files Are High-Conflict

i18n JSON files (en.json, ru.json, etc.) are modified by many tasks. When editing:

1. Surgical edits only. Never rewrite the entire file or large blocks. Add/rename only the specific keys you need.
2. Never delete keys unless the task explicitly requires it. Other code may reference them.
3. Always add to ALL locale files simultaneously. If you add a key to en.json, add it to ru.json too (and vice versa).
4. Verify key references before renaming. grep -r "old.key.name" src/ to find all usages. Update code references or keep the old key as alias.

Key Naming Convention

Use nested JSON objects with dot-path access:

{
  "section": {
    "subsection": {
      "key": "Value"
    }
  }
}

Access: t("section.subsection.key")

Pattern: {feature}.{context}.{label|hint|tooltip|action}

Adding Keys Checklist

1. Add key to ALL locale JSON files
2. Use {{ variable }} for interpolation: "greeting": "Hello, {{ name }}"
3. Run tests — i18n-dependent tests will catch missing keys
4. Check for dead keys: search codebase for removed t("...") calls

Worktree Warning

When working in a git worktree, your copy of i18n files may be outdated. Other tasks may have added keys to main after your branch point. Your edits must be additive only — never remove or reorder existing keys.
