+## Making changes
+
+### Tests
+
+Whenever possible, changes should be accompanied by non-trivial tests that meaningfully exercise the core functionality of the new code being introduced.
+
+All tests are in the `Test/` directory at the repo root. Fast unit tests are in the `Test/L0` directory and by convention have the suffix `L0.cs`. For example: unit tests for a hypothetical `src/Runner.Worker/Foo.cs` would go in `src/Test/L0/Worker/FooL0.cs`.
+
+Run tests using this command:
+
+```sh
+cd src && ./dev.sh test
+```
+
+### Formatting
+
+After editing .cs files, always format the code using this command:
+
+```sh
+cd src && ./dev.sh format
+```
+
+### Feature Flags
+
+Wherever possible, all changes should be safeguarded by a feature flag; `Features` are declared in [Constants.cs](src/Runner.Common/Constants.cs).

docs/adrs/0276-problem-matchers.md

@@ -250,6 +250,42 @@ Two problem matchers can be used:
 }
 ```
 
+#### Default from path
+
+The problem matcher can specify a `fromPath` property at the top level, which applies when a specific pattern doesn't provide a value for `fromPath`. This is useful for tools that don't include project file information in their output.
+
+For example, given the following compiler output that doesn't include project file information:
+
+```
+ClassLibrary.cs(16,24): warning CS0612: 'ClassLibrary.Helpers.MyHelper.Name' is obsolete
+```
+
+A problem matcher with a default from path can be used:
+
+```json
+{
+    "problemMatcher": [
+        {
+            "owner": "csc-minimal",
+            "fromPath": "ClassLibrary/ClassLibrary.csproj",
+            "pattern": [
+                {
+                    "regexp": "^(.+)\\((\\d+),(\\d+)\\): (error|warning) (.+): (.*)$",
+                    "file": 1,
+                    "line": 2,
+                    "column": 3,
+                    "severity": 4,
+                    "code": 5,
+                    "message": 6
+                }
+            ]
+        }
+    ]
+}
+```
+
+This ensures that the file is rooted to the correct path when there's not enough information in the error messages to extract a `fromPath`.

 #### Mitigate regular expression denial of service (ReDos)
 
 If a matcher exceeds a 1 second timeout when processing a line, retry up to two three times total.

+### Common Issues

+# - admin:org (for organization-level runners)
+export RUNNER_CFG_PAT=your_token_here
+echo $RUNNER_CFG_PAT  # Verify it's set

 > IMPORTANT: Building your own runner is critical for the dev inner loop process when contributing changes.  However, only runners built and distributed by GitHub (releases) are supported in production.  Be aware that workflows and orchestrations run service side with the runner being a remote process to run steps.  For that reason, the service can pull the runner forward so customizations can be lost.

+## Quick Setup
+
+1. **Download** the latest runner from [releases](https://github.com/actions/runner/releases)
+2. **Extract** the downloaded archive: `tar xzf actions-runner-osx-x64-*.tar.gz`
+3. **Run** `./config.sh` to configure the runner
+4. **Install** as a service: `sudo ./svc.sh install` and `sudo ./svc.sh start`
+
+## System Requirements
+
+### macOS Version
+- macOS 10.15 (Catalina) or later
+- Both Intel (x64) and Apple Silicon (ARM64) are supported
+
+### Required Tools
+
+#### Homebrew (Recommended)
+Install Homebrew for easy package management:
+```bash
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+```
+
+#### Development Tools
+```bash
+# Install Xcode Command Line Tools
+xcode-select --install
+
+# Install essential development tools via Homebrew
+brew install git curl wget
+```
+
+### .NET Runtime
+- .NET 6.0 runtime (automatically included with the runner)
+
+## Setup Steps
+
+### 1. Download and Extract
+```bash
+# Create runner directory
+mkdir ~/actions-runner && cd ~/actions-runner
+
+# Download latest release (replace with actual version)
+curl -O -L https://github.com/actions/runner/releases/download/v2.xyz.z/actions-runner-osx-x64-2.xyz.z.tar.gz
+
+# Extract
+tar xzf ./actions-runner-osx-x64-2.xyz.z.tar.gz
+```
+
+### 2. Configure
+```bash
+./config.sh --url https://github.com/YOUR_ORG/YOUR_REPO --token YOUR_TOKEN
+```
+
+### 3. Run as Service (macOS)
+```bash
+# Install as launchd service
+sudo ./svc.sh install
+
+# Start the service
+sudo ./svc.sh start
+
+# Check status
+sudo ./svc.sh status
+```
+
+### 4. Run Interactively (Alternative)
+```bash
+./run.sh
+```
+
+## macOS-Specific Considerations
+
+### Security & Privacy
+- Allow the runner executable through macOS Gatekeeper
+- Grant necessary permissions in System Preferences > Security & Privacy
+
+### Code Signing
+For repositories that build macOS applications:
+```bash
+# Install certificates for code signing
+security import developer_certificates.p12 -k ~/Library/Keychains/login.keychain
+```
+
+### Xcode Integration
+If building iOS/macOS apps:
+```bash
+# Install Xcode from App Store or developer portal
+# Set Xcode path
+sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**Permission Denied:**
+```bash
+chmod +x ./config.sh ./run.sh ./svc.sh
+```
+
+**Gatekeeper Issues:**
+```bash
+# Allow unsigned binary to run
+sudo spctl --master-disable
+# Or specifically allow the runner
+sudo spctl --add ./bin/Runner.Listener
+```
+
+**Service Not Starting:**
+```bash
+# Check system logs
+sudo ./svc.sh status
+tail -f ~/Library/Logs/Runner_*.log
+```
+
+**Path Issues:**
+```bash
+# Ensure proper PATH in your shell profile
+echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.zshrc
+source ~/.zshrc
+```

+# Enable required Windows features (run as Administrator)
+Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux
+```
+
+### Visual Studio Build Tools (For builds requiring compilation)
+For repositories that need to compile code, install:
+
+- **Visual Studio 2017 or newer** [Install here](https://visualstudio.microsoft.com)
+- **Visual Studio 2022 17.3 Preview or later** (for ARM64) [Install here](https://docs.microsoft.com/en-us/visualstudio/releases/2022/release-notes-preview)
+
+### Git for Windows
+- **Git for Windows** [Install here](https://git-scm.com/downloads) (required for repository operations)
+
+## Common Setup Steps
+
+### 1. Create Runner Directory
+```cmd
+mkdir C:\actions-runner
+cd C:\actions-runner
+```
+
+### 2. Download and Extract
+```powershell
+# Download latest release
+Invoke-WebRequest -Uri "https://github.com/actions/runner/releases/download/v2.xyz.z/actions-runner-win-x64-2.xyz.z.zip" -OutFile "actions-runner.zip"
+# Extract
+Expand-Archive -Path "actions-runner.zip" -DestinationPath "."
+```
+
+### 3. Configure
+```cmd
+.\config.cmd --url https://github.com/YOUR_ORG/YOUR_REPO --token YOUR_TOKEN
+```
+
+### 4. Run as Service
+```cmd
+# Install service
+.\svc.sh install
+# Start service  
+.\svc.sh start
+```
+
+## Troubleshooting
+
+### Common Issues
+
+**PowerShell Execution Policy:**
+```powershell
+Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
+```
+
+**Windows Defender/Antivirus:**
+- Add runner directory to antivirus exclusions
+- Exclude `Runner.Listener.exe` and `Runner.Worker.exe`
+
+**Firewall Issues:**
+```powershell
+# Allow runner through Windows Firewall
+New-NetFirewallRule -DisplayName "GitHub Actions Runner" -Direction Inbound -Protocol TCP -LocalPort 443 -Action Allow
+```
+
+**Permission Issues:**
+- Run `config.cmd` as Administrator
+- Ensure the runner user has "Log on as a service" rights
