# DigiDala — Alpha 50.6.9 Changeset

## Goal

Continue the UI cleanup block after `v0.4.0-alpha.50.6.8` by removing obsolete sidebar UI, fixing the Archive return/navigation initialization path, and making Mandala navigation headings compact and consistent.

## Scope

- Remove the legacy sidebar blocks marked `future`, `preview` and `immutable`.
- Remove the corresponding dead Mini App DOM references and CSS.
- Initialize the Mandala navigation catalog before archive routes are handled.
- Make the Archive `К мандалам` action resilient when the catalog is not yet loaded.
- Keep `Архив` visible as the only topbar action on mobile.
- Keep Mandala titles on one visual line with ellipsis when necessary.
- Show the Mandala number as a small secondary `#NNN` label instead of embedding it in the large heading.
- Add focused unit checks for the navigation and heading changes.

## Explicitly not changed

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

## Verification

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

## Manual QA target

At minimum verify:

- Telegram bot → direct open of every existing Mandala type.
- Archive → `К мандалам` → Sandbox.
- From Sandbox, circular navigation through Support, Small Creative, Large Creative, Special and Competitive.
- The previously reported `404` no longer occurs when entering Special after coming from the Archive path.
- Long Mandala titles remain on one line on desktop and mobile.
- `#001`-style Mandala numbers are visually secondary and no longer dominate the heading.
- Mobile Telegram still exposes the permanent `Архив` entry.
- Removed legacy sidebar blocks are absent on ordinary Mandala pages.
