I see - the project is called `guru-connect` (with hyphen), not `guruconnect`. And it was created on another machine at `/home/guru/claude-projects/`. Let me check if it's in Gitea:


Bash

curl -s --max-time 5 "https://git.azcomputerguru.com/api/v1/repos/azcomputerguru/guru-connect" 2>&1

Check guru-connect repo


not found

not found


The GuruConnect project doesn't exist in Gitea yet. Based on the session log, it was created locally on another machine but never pushed.

## Summary

**Dev Tools on This Machine:**
| Tool | Status |
|------|--------|
| Rust (rustc/cargo) | ✅ v1.92.0 |
| Node.js | ✅ v24.11.0 |
| npm | ✅ v11.6.1 |
| protoc | ❌ Not installed |
| MSVC (cl) | ❌ Not in PATH (may need VS Developer Command Prompt) |

**GuruConnect Status:**
The `guru-connect` project was created on another machine (localadmin/WSL) but **hasn't been pushed to Gitea yet**. The repo doesn't exist on Gitea.

**To build GuruConnect on this Windows machine, you need:**
1. `protoc` - Install with `winget install protocolbuffers.protobuf`
2. Visual Studio Build Tools with C++ workload (or use VS Developer Command Prompt)
3. Push the guru-connect code from the original machine to Gitea first

Would you like me to:
1. Install protoc on this machine?
2. Help you push the guru-connect project from the other machine first?


I'm installing the requisites.  Did the other machine not push?

Phase 1: Create migration 007_authorization.sql

Phase 1: Create server/src/authz/mod.rs

Phase 1: Create server/src/authz/permissions.rs

Phase 1: Update server/src/auth/mod.rs with enhanced AuthUser

Phase 1: Create server/src/db/user_organizations.rs

Phase 2: Create server/src/api/organizations.rs

Phase 2: Update login to include org claims

Run tests

Add dashboard API types for organizations

Phase 3: Add scoping to data API endpoints


The user is asking if the other machine pushed the guru-connect repo to Gitea. Based on my checks, the repo doesn't exist on Gitea - the API returned "not found". Let me check the session logs more carefully to see if there was a push attempt.


Let me check the session logs to see what happened:


grep -i "push\|commit\|remote\|gitea" "C:/Users/MikeSwanson/claude-projects/session-logs/2025-12-21-guruconnect-session.md" 2>&1

Search for push/commit info


Created the GuruConnect project - a ScreenConnect-like remote desktop solution that will integrate with GuruRMM.
1. **Agent** (`agent/`) - Windows remote desktop agent
   - RemoteViewer component (canvas-based rendering)
   - useRemoteSession hook for WebSocket connection
        │   ├── RemoteViewer.tsx
        │   └── useRemoteSession.ts


The grep didn't show any push or gitea mentions. Let me check the build session log too, and also search for git-related commands in both logs.

Looking at the session logs, there's no mention of pushing to Gitea. The code was created locally on another machine (the Mac with WSL or another machine) but was never pushed to Gitea. The session logs mention "committed to local git" but no remote push.

Let me check the build session log for any git push references.


grep -i "push\|remote\|gitea\|origin" "C:/Users/MikeSwanson/claude-projects/session-logs/2025-12-21-guruconnect-build.md" 2>&1

Check build log for push


   - `RemoteViewer.tsx` - Canvas-based frame rendering
   - `useRemoteSession.ts` - WebSocket connection hook


The grep didn't find any push/remote/gitea mentions in the build log either. The code was committed locally but never pushed to Gitea. Let me confirm this and explain to the user.


**No, it was never pushed.** The session logs show:

- The build session says: "All GuruConnect files committed to local git"
- No mention of `git remote add`, `git push`, or Gitea anywhere

The code exists only on the other machine (looks like it was `/home/guru/claude-projects/guru-connect/` on a Linux/WSL system, mapped to `C:\Users\localadmin\`).

**To get the code to this machine, you'll need to:**

1. On the original machine, push to Gitea:
   ```bash
   cd ~/claude-projects/guru-connect
   git remote add origin ssh://git@172.16.3.20:2222/azcomputerguru/guru-connect.git
   # First create the repo in Gitea web UI, then:
   git push -u origin main
   ```

2. Then clone here once it's pushed

Or alternatively, if you have direct access to that machine, you could copy the files directly.

Which machine was the guru-connect project created on? The Mac?


<command-message>sync</command-message>
<command-name>/sync</command-name>


Sync Claude Code preferences and commands from gitea to this local machine.

## Steps to perform:

1. **Clone or pull the claude-projects repo** from gitea:
   ```
   Repository: ssh://git@172.16.3.20:2222/azcomputerguru/claude-projects.git
   ```

2. **Check if repo exists locally** at `~/claude-projects/`
   - If exists: `git pull gitea main`
   - If not: Clone it first

3. **Copy the .claude directory** from the repo to apply commands:
   - Source: `~/claude-projects/.claude/commands/`
   - These slash commands will now be available

4. **Apply global permissions** - Copy the shared settings to make them permanent:
   ```bash
   cp ~/claude-projects/claude-settings/settings.json ~/.claude/settings.json
   ```
   This applies the comprehensive permission set so you get fewer prompts.

5. **Read and apply any project settings** from `~/claude-projects/.claude/settings.local.json` if present

6. **Report what was synced**:
   - List available slash commands
   - Show any settings applied
   - Show recent session logs available for context

7. **Read the most recent session log** to get context on what was worked on recently

This ensures all your machines have the same Claude Code setup and can pick up where you left off.


cd "C:\Users\MikeSwanson\claude-projects" && git pull

Pull latest from gitea

**Ready to build?** Let me check if protoc is installed now:


where protoc 2>&1 && protoc --version 2>&1

Check for protoc


Error: Exit code 1
INFO: Could not find files for the given pattern(s).


Ah, the other PC (localadmin), not the Mac. Got it.

**protoc not found yet.** Once you've finished installing the prerequisites, let me know and I'll attempt the build. The requirements are:

1. **protoc** - `winget install protocolbuffers.protobuf` (or download from GitHub releases)
2. **MSVC/Visual Studio Build Tools** with C++ workload

When ready, I'll run:
```
cargo build -p guruconnect-agent --release
```


Got it - the GuruConnect project was created on the **other PC** (the `localadmin` Windows machine), not the Mac. That explains the path `/home/guru/` which was likely WSL on that Windows PC.

The repo is now cloned here and ready. Just let me know when you've finished installing protoc and the MSVC build tools, and I'll attempt the agent build.


protoc is installed, using the command specified about an hour ago.

Phase 1: Create migration 007_authorization.sql

Phase 1: Create server/src/authz/mod.rs

Phase 1: Create server/src/authz/permissions.rs

Phase 1: Update server/src/auth/mod.rs with enhanced AuthUser

Phase 1: Create server/src/db/user_organizations.rs

Phase 2: Create server/src/api/organizations.rs

Phase 2: Update login to include org claims

Run tests

Add dashboard API types for organizations

Phase 3: Add scoping to data API endpoints


The user says protoc is installed. Let me verify it's available and then try to build the guruconnect-agent.


Verify protoc installed


Error: Exit code 127
/usr/bin/bash: line 1: protoc: command not found


The bash shell doesn't see it. It might have been installed but the PATH wasn't updated in this session. Let me check common Windows installation paths.


ls "C:/Program Files/protobuf/bin/protoc.exe" 2>&1 || ls "C:/ProgramData/chocolatey/bin/protoc.exe" 2>&1 || ls "$LOCALAPPDATA/Microsoft/WinGet/Packages/"*protoc*/bin/protoc.exe 2>&1 || where.exe protoc 2>&1

Sorry:PS C:\Users\MikeSwanson> winget install protocolbuffers.protobuf
No package found matching input criteria.


Let me try checking where winget installs things or if it's under a different path.


powershell.exe -Command "Get-Command protoc -ErrorAction SilentlyContinue | Select-Object -ExpandProperty Source" 2>&1

Find protoc via PowerShell


Exit code 1


The winget package name is wrong. Let me help the user find the correct package or download it directly.


The winget package name isn't right. Let me find the correct one:


powershell.exe -Command "winget search protobuf" 2>&1

Search for protobuf package

The correct package is `Google.Protobuf`. Let me tell the user.


The correct package is `Google.Protobuf`:

```powershell
winget install Google.Protobuf
```

Or you can download directly from GitHub:
- https://github.com/protocolbuffers/protobuf/releases
- Get `protoc-XX.X-win64.zip`, extract, and add the `bin` folder to your PATH

protoc is installed. The user will need to restart the shell or we can try finding the path directly. Let me check the common installation location for winget packages.


Protoc installed. Let me find its path and try the build:


ls "$LOCALAPPDATA/Microsoft/WinGet/Links/protoc.exe" 2>&1 || find /c/Users/MikeSwanson/AppData -name "protoc.exe" 2>/dev/null | head -3

Find protoc path


ls: cannot access '/Microsoft/WinGet/Links/protoc.exe': No such file or directory
/c/Users/MikeSwanson/AppData/Local/Microsoft/WinGet/Links/protoc.exe
/c/Users/MikeSwanson/AppData/Local/Microsoft/WinGet/Packages/Google.Protobuf_Microsoft.Winget.Source_8wekyb3d8bbwe/bin/protoc.exe


Found it. Let me add it to PATH temporarily and try the build.


export PATH="$PATH:/c/Users/MikeSwanson/AppData/Local/Microsoft/WinGet/Links" && protoc --version

Test protoc with updated PATH


libprotoc 33.2


protoc works. Now let me try to build the guruconnect-agent. I need to make sure the PATH includes protoc for the build.


Protoc works. Now let's build the agent:


export PATH="$PATH:/c/Users/MikeSwanson/AppData/Local/Microsoft/WinGet/Links" && cd "C:/Users/MikeSwanson/claude-projects/guru-connect" && cargo build -p guruconnect-agent --release 2>&1

Build guruconnect-agent

There are compilation errors. The code was written for a different version of the `windows` crate. The API has changed. Let me look at the specific issues:

1. `windows::Win32::Foundation::BOOL` doesn't have `Ok` method in newer versions
2. `CreateTexture2D` signature changed (takes 3 args instead of 2)
3. `as_bool()` method on Result instead of BOOL
4. Type mismatches with `wScan` field

Let me check what version of the windows crate is being used and fix these issues.


Build failed due to Windows crate API changes. The code was written for an older version of the `windows` crate but the current version has breaking changes. Let me fix these:

The code uses `windows = "0.58"`. The issue is that the Windows crate version 0.58 has different API signatures than what was coded against. Looking at the errors:

1. `windows::Win32::Foundation::BOOL::Ok` - In newer versions, BOOL functions don't return `Result<BOOL>`, they return `BOOL` directly, and there's no `.Ok` method on `BOOL`.

2. `CreateTexture2D` - The signature changed, now takes an output parameter instead of returning the texture.

3. `as_bool()` on Result - The function returns a `Result<(), Error>` not a `BOOL`

Let me check the exact files that need fixing and update them to work with the current API.

    fn drop(&mut self) {
        // Release any held frame
        unsafe {
            self.duplication.ReleaseFrame().ok();
        }
    }
}


btw do we need to account for those API changes if we're supporting older machines?  Or is this only a build issue?


Looking at the errors, the main issue is with line 175:

```rust
let staging = self.device.CreateTexture2D(&desc, None)
    .context("Failed to create staging texture")?;
```

In the newer version of the Windows crate, `CreateTexture2D` takes 3 arguments:
1. `pdesc: *const D3D11_TEXTURE2D_DESC`
2. `pinitialdata: Option<*const D3D11_SUBRESOURCE_DATA>`
3. `pptexture: Option<*mut Option<ID3D11Texture2D>>`

And returns `Result<(), Error>` instead of `Result<ID3D11Texture2D, Error>`.

Let me also check the other files with errors (gdi.rs, display.rs, keyboard.rs).

The user is asking if the API changes are a build issue or if they affect runtime compatibility with older Windows machines.

The answer is: **This is only a build issue**. The changes are in the *Rust binding* crate (`windows-rs`), not in the actual Windows API. The Windows crate is just Rust bindings that generate FFI calls to the same underlying Windows DLLs.

The underlying Windows APIs (DXGI, GDI, etc.) haven't changed - they're part of Windows and are backward compatible. The issue is that the `windows` crate (which provides the Rust bindings) has evolved its API surface to be more idiomatic Rust, but this doesn't affect what Windows DLLs are called at runtime.

So:
- **Build issue**: The Rust code needs to match the Rust binding signatures in `windows` crate 0.58
- **Runtime**: The compiled binary will work on older Windows machines (Windows 8+ for DXGI, any Windows for GDI)

Let me fix the code to match the current `windows` crate API.


**This is only a build issue**, not a runtime compatibility problem.

The `windows` crate is just Rust bindings to the Windows API. The actual Windows DLLs (DXGI, GDI, etc.) haven't changed - the crate maintainers just changed how the Rust wrappers work (e.g., how they return results). The compiled binary will still call the same Windows APIs and work on older machines.

So the fix is just updating the Rust code to match the current crate's API signatures. Let me fix these files:
