Mini Chat + Downloads + Windows Installer: Tego OS v3.0.0's Desktop Triple Play

Put the digital avatar into the daily workflow — not as a new app to launch, but as something you summon, use, and dismiss.

Why the desktop matters

A great backend still meets users through the client they touch every day. v3.0.0 ships three things on the desktop with a single goal:

Make the digital avatar feel like Spotlight or Raycast — summon, use, dismiss, without breaking the main task.

Three things, one section each.

1. Mini Chat — the always-on-top "pocket avatar"

Design goal

Most digital-avatar usage isn't "open the app and chat for a while." It's:

• Writing a doc → ask a quick definition;
• Reading code → ask about an API;
• Handling a ticket → summon the IT assistant;
• Writing a listing → have the avatar pull a competitor review.

The key for these flows: the entry point must be lighter than launching the main app, or users won't use it.

Five experience details

1. Independent Tauri window — compact, frameless, always-on-top

Mini Chat isn't a child window of the main app — it's a fully independent Tauri webview. Compact + frameless + always-on-top, so it can sit in the corner of your screen for hours without disrupting your main task.

2. Same connection — no split conversations

Mini Chat shares the same session connection as the main window. Type a couple of lines in Mini Chat, then open the main window — the history is continuous, and vice versa.

3. Global shortcut, à la Spotlight / Raycast

Configurable global shortcut to summon / hide. Default behavior models Spotlight / Raycast:

• Summon → grab focus immediately;
• Already visible → hide;
• ESC → hide (don't quit);
• Configuration lets enterprises standardize the shortcut org-wide.

4. Cross-window sync

Both windows always show the same conversation. Type in Mini Chat, then open the main window for the full thread — no refresh, no reconnect.

5. Lazy-create + reuse — webview created on first invocation

Mini Chat's webview is lazily created — not at app startup but on first invocation, then kept alive. A meaningful optimization:

• App startup isn't slowed by Mini Chat;
• Subsequent summons respond in milliseconds;
• If a user never uses Mini Chat, the webview is never created.

This is what makes Mini Chat an entry point that's "actually used every day," instead of a feature "installed and never opened again."

2. Downloads — a unified download center

The pain

In v2.x, when an enterprise distributed Tego across endpoints, they hit:

• Desktop / mobile / CLI installers scattered across multiple places;
• Different employees on different versions ("I'm on 0.x, you're on 0.y");
• Download links going stale, IT support overwhelmed.

The v3.0.0 fix

A single Downloads center that aggregates installers across endpoints:

• Desktop — macOS / Windows / Linux;
• Mobile — Android / iOS;
• CLI — single binary;
• Version, update time, signature fingerprint visible at a glance.

Once enterprise IT has the environment, they share one Downloads URL with the whole company; the rest takes care of itself.

Supporting features

• Version compatibility — each installer marks the minimum / recommended server version;
• Silent download — links can be configured for batch distribution inside corporate networks;
• Signature fingerprints — IT can verify signatures, defending against repackaged binaries.

3. Windows NSIS installer — full rewrite

Windows is where v3.0.0's desktop experience improved most. The v2.x installer regularly hit:

• AV false positives, install interrupted;
• Wrong install-path permissions, no log writes after launch;
• Old version residue, new install fails;
• Oversized package straining corporate bandwidth.

What v3.0.0 fixes

1. NSIS installer fully rewritten — restructured to remove hidden writes from the legacy script;
2. Silent install — supports /S, friendly to SCCM / Intune mass deployment;
3. Auto-uninstall old version — detects and removes prior versions before installing;
4. Package slimming — removes redundant deps and debug symbols, much smaller;
5. Signature compatibility — works with mainstream AV signature checks, fewer false positives;
6. Optional install path — enterprises can specify a standardized directory.

Whether Tego "installs and upgrades reliably on Windows" is the hard gate for any enterprise rollout. v3.0.0 lowers that gate by more than one notch.

Three features, one whole

Mini Chat, Downloads and the Windows installer look like three unrelated features. In the context of "put the digital avatar into daily work," they're a single package:

• Windows installer → it installs;
• Downloads center → on the right version, fully equipped;
• Mini Chat → after installation, used daily.

Drop any one and the desktop experience shows obvious gaps.

Integration with the server

Desktop isn't only a client experience — it integrates deeply with the v3.0.0 server:

• Mini Chat and main-window session sync rely on v3.0.0's unified session contract;
• When desktop runs in per_user, each Windows account maps to its own runtime (no cross-colleague leak);
• Desktop access to skills / memory / templates flows through v3.0.0's gateway + 3-layer fallback;
• All desktop interactions feed into BusinessMonitor's engagement panel.

The desktop is the "last mile" of v3.0.0's end-to-end experience.

Getting started

1. Pull your platform's installer from the Downloads center;
2. (Windows) confirm enterprise IT has signature trust configured;
3. Install and log in;
4. Configure the global shortcut to summon Mini Chat;
5. Drag Mini Chat to the corner of your screen and start your day.
