 - Batch 4Z expanded the supported locale set to the six UN official languages: Arabic, Chinese, English, French, Russian, and Spanish. Arabic, French, Russian, and Spanish now have full client-owned UI resource coverage, with key parity, fallback-ratio, and interpolation-placeholder tests guarding the generated translations. Arabic does not enable RTL layout direction in this batch.
 - Batch 5A added Brazilian Portuguese (`pt-BR`) resource coverage, language selector labels, i18next registration, and system-locale mapping for `pt-BR` and bare `pt`. Non-Brazilian Portuguese regional locales remain unsupported until a matching resource is added.
 - Batch 5B added Korean (`ko`) resource coverage, language selector labels, i18next registration, and system-locale mapping for `ko` and Korean regional locales.
-- Batch 5C migrated provider-usage chrome across the Usage settings tab and context-meter tooltip: loading/error/empty states, refresh actions, usage/remaining labels, availability statuses, reset/run-out timing, and updated-at text. Provider names, plan labels, usage-window labels, balance/detail labels, source labels, and raw provider errors remain runtime values.
+- Batch 5C migrated provider-usage chrome across the Usage settings tab and context-meter tooltip: loading/error/empty states, refresh actions, usage/remaining labels, availability statuses, reset/run-out timing, and updated-at text. Known generic usage labels (`session`, `weekly`, `code_review`, and `credits`) are localized by ID; provider names, plan labels, provider-specific labels, detail labels, source labels, and raw provider errors remain runtime values.
