# DigiDala — Alpha 50.9 Changeset

## Scope

Alpha.50.9 introduces the first localization foundation for the DigiDala Mini App.

### Mini App localization

- Added dedicated i18n modules for English and Russian.
- Added automatic locale selection from Telegram `language_code`.
- Added persisted manual locale selection with manual preference taking priority.
- English is the fallback locale.
- Moved approved user-facing Russian/English copy out of the primary renderer where localization keys are now used.
- Added localization coverage for the approved Mini App interface, states, errors, Archive, completion and ritual UI.
- Added localized accessibility labels and dynamic UI strings.
- Added regression coverage for locale selection and localized UI bindings.

### Campaign localization

- Added campaign localization storage.
- Campaign titles, descriptions and goal text can be stored independently for RU and EN.
- Active campaign presentation resolves localized content with English fallback.
- Archive presentation resolves historical localized campaign content where localized archive data exists.
- Campaign localization data is stored separately from Mandala mechanics and cell state.

### Bot-managed campaign content

- Competitive campaign creation/editing supports localized campaign content.
- Backend campaign updates no longer accept a standalone legacy `description` without localization data.

### Existing campaign safety

No changes were made to:

- Mandala cell ownership;
- Mandala cycles;
- Pix balances or cell prices;
- payment verification;
- destruction lifecycle;
- campaign activation and queue mechanics;
- archive mechanics;
- Mandala routing or share-link mechanics.

The existing Special/Daughter campaign remains the same campaign object; the localization layer only adds localized presentation data.

This document records the Alpha.50.9 localization foundation checkpoint. It was superseded by the subsequent Alpha.50.9.1 and Alpha.50.9.2 release chain, which completed the Telegram bot localization and its follow-up QA. No separate final release/Telegram-QA claim is made for Alpha.50.9 itself.
