# DigiDala — Alpha 50.6.10 Changeset

## Goal

Continue the UI cleanup after `v0.4.0-alpha.50.6.9` by refining the archive presentation and return navigation, and by making Competitive Mandala numbering consistent with the other Mandala types.

## Scope

- Rename the user-facing archive to **Эфирный след (архив)** in the Mini App archive entry and archive views.
- Show the Mandala number as a compact `#NNN` secondary label for Competitive Mandalas as well as ordinary Mandalas.
- Add a top-right `← Назад` control to the archive index that returns to the route from which the archive was opened; direct archive entry falls back to Sandbox.
- Add a top-right `← Назад` control to individual archive views that returns to the archive index.
- Remove the ambiguous `Открыть архив в Telegram` action from individual archive views.
- Remove the duplicate bottom archive-index button; keep the campaign-space return action in archive detail.
- Add focused regression coverage for archive naming, return routing, header controls and Competitive number presentation.
- Present archive participants as a compact three-column table while preserving participant-trace highlighting.

## Explicitly not changed

- No backend/API behavior is changed.
- No Mandala lifecycle semantics are changed.
- No archive data model is changed.
- No changes are made to the circular navigation algorithm.
- No campaign archive deep-link API behavior is changed.

## Verification

Automated verification: pending.
Deployment: pending.
Manual Telegram QA: pending.

## Manual QA target

At minimum verify:

- The topbar archive entry reads `Эфирный след (архив)` on desktop and mobile.
- Archive index is titled `Эфирный след (архив)`.
- Opening the archive from an ordinary Mandala and pressing the top-right `← Назад` returns to that same Mandala.
- Opening the archive from Special or Competitive and pressing `← Назад` returns to the same space.
- Direct archive entry has a safe Sandbox fallback for `← Назад`.
- Opening an archive item and pressing the top-right `← Назад` returns to the archive index without losing the original archive return target.
- The individual archive view no longer offers `Открыть архив в Telegram`.
- Competitive Mandalas show a compact `#NNN` secondary number consistent with other Mandalas.
- Archive and navigation visuals remain readable on mobile Telegram.
