# CoH3 Build Studio 3.5.0 — Ranked Achievements preview & Command Desk

Prepared 5 October 2026. This is a release candidate; it has not been deployed to the production server or tested in a real Windows Ranked match.

## Achievements

- Exactly 100 Studio achievements: 25 each for US Forces, British Forces, Wehrmacht and Afrika Korps.
- English and Polish titles and conditions, faction tabs, search, status filters, progress sorting and unlock history.
- Details show the qualifying condition, confirmed progress, evidence match IDs and separate match/unlock verification dates.
- A tracking status explains whether the app is connected. Previously synchronized verified history remains readable offline.
- Main-process presence tracking continues when the app window is minimized. Match detection does not need to be enabled.
- Server-side session challenges, match verification jobs, deduplicated contributions, notification events and an audit history are implemented. New achievements cannot be granted through client-provided counters or imported replay metadata.

**Availability:** none of the 100 achievements can currently be earned in production. The catalog is a working preview. Live Relic responses confirm that match and leaderboard data exist, but they do not yet establish the complete required evidence: full-match human control, validated game duration, statistical counter semantics, patch mappings and trusted Battlegroup provenance. The app labels these challenges as unavailable. An open-app session alone does not make a match eligible.

Once those capabilities are validated, only confirmed Ranked PvP 1v1–4v4 matches will qualify, with Studio open before and throughout the match. These are Studio achievements, separate from Steam achievements for the game. No medals, currencies or gameplay rewards are added.

## Website

- Reworked homepage with dark steel panels, brass accents, the app's bundled artwork and a command-desk layout.
- Optional muted background animation. Video is only downloaded after choosing Background motion, pauses when the browser tab is hidden, and respects reduced-motion preferences.
- Compact expandable tool index replaces the repetitive feature-card grid.
- Existing build, map, comparison, tactical animation and community demos remain available in English and Polish.
- Added 3.4.0 history and clearly labelled 3.5.0 preview notes. The existing public 3.4.0 download and stable update feed are preserved.

## Deployment notes

The new achievements screen requires the matching backend and additive migration 008. Existing Steam login, builds, community, overlays and offline planning are retained. The website package runs as static files without a Node.js server. Do not announce 100 earnable achievements or activate automatic distribution before Windows acceptance and source validation are complete.
