+## 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).

+          This workflow attempts to automatically fix TypeScript compatibility issues that may arise from npm audit fixes.
+
+          ⚠️ **Manual Review Required**: The build is currently failing after automated fixes were attempted.
+
+          Common issues and solutions:
+          - Check for TypeScript version compatibility with Node.js types
+          - Review breaking changes in updated dependencies
+          - Consider pinning problematic dependency versions temporarily
+          - Review tsconfig.json for compatibility settings
+
+          **Automated Fix Strategy**:
+          1. Run npm audit fix with proper error handling
+          2. Update @types/node to latest compatible version
+          3. Try Node 20 specific @types/node version if needed
+          4. Clean reinstall dependencies if conflicts persist
+          5. Update TypeScript compiler if necessary

+          
+          **Changes made:**

+          **⚠️ Security Fixes Applied - Build Issues Need Manual Resolution**
+          This update applies important security patches but causes build failures that require manual fixes.
+          
+          **Changes made:**
+          - Applied `npm audit fix --force` to resolve security vulnerabilities
+          - Updated package-lock.json with security patches
+          
+          **⚠️ Build Issues Detected:**
+          The build fails after applying security fixes, likely due to TypeScript compatibility issues with updated `@types/node`.
+          
+          **Required Manual Fixes:**
+          1. Review TypeScript compilation errors in the build output
+          2. Update TypeScript configuration if needed
+          3. Consider pinning `@types/node` to a compatible version
+          4. Run `npm run all` locally to verify fixes
+          
+          **Next steps:**
+          - **DO NOT merge until build issues are resolved**
+          - Apply manual fixes for TypeScript compatibility
+          - Test the hashFiles functionality still works as expected

+# DAP Cancellation Support
+
+**Status:** Implemented  
+**Author:** OpenCode  
+**Date:** January 2026
+
+## Problem
+
+When a cancellation signal for the current job comes in from the server, the DAP debugging session doesn't properly respond. If the runner is paused at a breakpoint waiting for debugger commands (or if a debugger never connects), the job gets stuck forever and requires manually deleting the runner.
+
+### Root Cause
+
+The `DapDebugSession.WaitForCommandAsync()` method uses a `TaskCompletionSource` that only completes when a DAP command arrives from the debugger. There's no mechanism to interrupt this wait when the job is cancelled externally.
+
+Additionally, REPL shell commands use `CancellationToken.None`, so they also ignore job cancellation.
+
+## Solution
+
+Add proper cancellation token support throughout the DAP debugging flow:
+
+1. Pass the job cancellation token to `OnStepStartingAsync` and `WaitForCommandAsync`
+2. Register cancellation callbacks to release blocking waits
+3. Add a `CancelSession()` method for external cancellation
+4. Send DAP `terminated` and `exited` events to notify the debugger before cancelling
+5. Use the cancellation token for REPL shell command execution
+
+## Progress Checklist
+
+- [x] **Phase 1:** Update IDapDebugSession interface
+- [x] **Phase 2:** Update DapDebugSession implementation
+- [x] **Phase 3:** Update StepsRunner to pass cancellation token
+- [x] **Phase 4:** Update JobRunner to register cancellation handler
+- [ ] **Phase 5:** Testing
+
+## Files to Modify
+
+| File | Changes |
+|------|---------|
+| `src/Runner.Worker/Dap/DapDebugSession.cs` | Add cancellation support to `OnStepStartingAsync`, `WaitForCommandAsync`, `ExecuteShellCommandAsync`, add `CancelSession` method |
+| `src/Runner.Worker/StepsRunner.cs` | Pass `jobContext.CancellationToken` to `OnStepStartingAsync` |
+| `src/Runner.Worker/JobRunner.cs` | Register cancellation callback to call `CancelSession` on the debug session |
+
+## Detailed Implementation
+
+### Phase 1: Update IDapDebugSession Interface
+
+**File:** `src/Runner.Worker/Dap/DapDebugSession.cs` (lines ~144-242)
+
+Add new method to interface:
+
+```csharp
+/// <summary>
+/// Cancels the debug session externally (e.g., job cancellation).
+/// Sends terminated event to debugger and releases any blocking waits.
+/// </summary>
+void CancelSession();
+```
+
+Update existing method signature:
+
+```csharp
+// Change from:
+Task OnStepStartingAsync(IStep step, IExecutionContext jobContext, bool isFirstStep);
+
+// Change to:
+Task OnStepStartingAsync(IStep step, IExecutionContext jobContext, bool isFirstStep, CancellationToken cancellationToken);
+```
+
+### Phase 2: Update DapDebugSession Implementation
+
+#### 2.1 Add cancellation token field
+
+**Location:** Around line 260-300 (field declarations section)
+
+```csharp
+// Add field to store the job cancellation token for use by REPL commands
+private CancellationToken _jobCancellationToken;
+```
+
+#### 2.2 Update OnStepStartingAsync
+
+**Location:** Line 1159
+
+```csharp
+public async Task OnStepStartingAsync(IStep step, IExecutionContext jobContext, bool isFirstStep, CancellationToken cancellationToken)
+{
+    if (!IsActive)
+    {
+        return;
+    }
+
+    _currentStep = step;
+    _jobContext = jobContext;
+    _jobCancellationToken = cancellationToken; // Store for REPL commands
+
+    // ... rest of existing implementation ...
+
+    // Update the WaitForCommandAsync call at line 1212:
+    await WaitForCommandAsync(cancellationToken);
+}
+```
+
+#### 2.3 Update WaitForCommandAsync
+
+**Location:** Line 1288
+
+```csharp
+private async Task WaitForCommandAsync(CancellationToken cancellationToken)
+{
+    lock (_stateLock)
+    {
+        _state = DapSessionState.Paused;
+        _commandTcs = new TaskCompletionSource<DapCommand>(TaskCreationOptions.RunContinuationsAsynchronously);
+    }
+
+    Trace.Info("Waiting for debugger command...");
+
+    // Register cancellation to release the wait
+    using (cancellationToken.Register(() =>
+    {
+        Trace.Info("Job cancellation detected, releasing debugger wait");
+        _commandTcs?.TrySetResult(DapCommand.Disconnect);
+    }))
+    {
+        var command = await _commandTcs.Task;
+
+        Trace.Info($"Received command: {command}");
+
+        lock (_stateLock)
+        {
+            if (_state == DapSessionState.Paused)
+            {
+                _state = DapSessionState.Running;
+            }
+        }
+
+        // Send continued event (only for normal commands, not cancellation)
+        if (!cancellationToken.IsCancellationRequested && 
+            (command == DapCommand.Continue || command == DapCommand.Next))
+        {
+            _server?.SendEvent(new Event
+            {
+                EventType = "continued",
+                Body = new ContinuedEventBody
+                {
+                    ThreadId = JobThreadId,
+                    AllThreadsContinued = true
+                }
+            });
+        }
+    }
+}
+```
+
+#### 2.4 Add CancelSession method
+
+**Location:** After `OnJobCompleted()` method, around line 1286
+
+```csharp
+/// <summary>
+/// Cancels the debug session externally (e.g., job cancellation).
+/// Sends terminated/exited events to debugger and releases any blocking waits.
+/// </summary>
+public void CancelSession()
+{
+    Trace.Info("CancelSession called - terminating debug session");
+
+    lock (_stateLock)
+    {
+        if (_state == DapSessionState.Terminated)
+        {
+            Trace.Info("Session already terminated, ignoring CancelSession");
+            return;
+        }
+        _state = DapSessionState.Terminated;
+    }
+
+    // Send terminated event to debugger so it updates its UI
+    _server?.SendEvent(new Event
+    {
+        EventType = "terminated",
+        Body = new TerminatedEventBody()
+    });
+
+    // Send exited event with cancellation exit code (130 = SIGINT convention)
+    _server?.SendEvent(new Event
+    {
+        EventType = "exited",
+        Body = new ExitedEventBody { ExitCode = 130 }
+    });
+
+    // Release any pending command waits
+    _commandTcs?.TrySetResult(DapCommand.Disconnect);
+
+    Trace.Info("Debug session cancelled");
+}
+```
+
+#### 2.5 Update ExecuteShellCommandAsync
+
+**Location:** Line 889-895
+
+Change the `ExecuteAsync` call to use the stored cancellation token:
+
+```csharp
+int exitCode;
+try
+{
+    exitCode = await processInvoker.ExecuteAsync(
+        workingDirectory: workingDirectory,
+        fileName: shell,
+        arguments: string.Format(shellArgs, command),
+        environment: env,
+        requireExitCodeZero: false,
+        cancellationToken: _jobCancellationToken);  // Changed from CancellationToken.None
+}
+catch (OperationCanceledException)
+{
+    Trace.Info("Shell command cancelled due to job cancellation");
+    return new EvaluateResponseBody
+    {
+        Result = "(cancelled)",
+        Type = "error",
+        VariablesReference = 0
+    };
+}
+catch (Exception ex)
+{
+    Trace.Error($"Shell execution failed: {ex}");
+    return new EvaluateResponseBody
+    {
+        Result = $"Error: {ex.Message}",
+        Type = "error",
+        VariablesReference = 0
+    };
+}
+```
+
+### Phase 3: Update StepsRunner
+
+**File:** `src/Runner.Worker/StepsRunner.cs`
+**Location:** Line 204
+
+Change:
+```csharp
+await debugSession.OnStepStartingAsync(step, jobContext, isFirstStep);
+```
+
+To:
+```csharp
+await debugSession.OnStepStartingAsync(step, jobContext, isFirstStep, jobContext.CancellationToken);
+```
+
+### Phase 4: Update JobRunner
+
+**File:** `src/Runner.Worker/JobRunner.cs`
+
+#### 4.1 Add cancellation registration
+
+**Location:** After line 191 (after "Debugger connected" output), inside the debug mode block:
+
+```csharp
+// Register cancellation handler to properly terminate DAP session on job cancellation
+CancellationTokenRegistration? dapCancellationRegistration = null;
+try
+{
+    dapCancellationRegistration = jobRequestCancellationToken.Register(() =>
+    {
+        Trace.Info("Job cancelled - terminating DAP session");
+        debugSession.CancelSession();
+    });
+}
+catch (Exception ex)
+{
+    Trace.Warning($"Failed to register DAP cancellation handler: {ex.Message}");
+}
+```
+
+Note: The `dapCancellationRegistration` variable should be declared at a higher scope (around line 116 with other declarations) so it can be disposed in the finally block.
+
+#### 4.2 Dispose the registration
+
+**Location:** In the finally block (after line 316, alongside dapServer cleanup):
+
+```csharp
+// Dispose DAP cancellation registration
+dapCancellationRegistration?.Dispose();
+```
+
+## Behavior Summary
+
+| Scenario | Before | After |
+|----------|--------|-------|
+| Paused at breakpoint, job cancelled | **Stuck forever** | DAP terminated event sent, wait released, job cancels normally |
+| REPL command running, job cancelled | Command runs forever | Command cancelled, job cancels normally |
+| Waiting for debugger connection, job cancelled | Already handled | No change (already works) |
+| Debugger disconnects voluntarily | Works | No change |
+| Normal step execution, job cancelled | Works | No change (existing cancellation logic handles this) |
+
+## Exit Code Semantics
+
+The `exited` event uses these exit codes:
+- `0` = job succeeded
+- `1` = job failed  
+- `130` = job cancelled (standard Unix convention for SIGINT/Ctrl+C)
+
+## Testing Scenarios
+
+1. **Basic cancellation while paused:**
+   - Start a debug job, let it pause at first step
+   - Cancel the job from GitHub UI
+   - Verify: DAP client receives terminated event, runner exits cleanly
+
+2. **Cancellation during REPL command:**
+   - Pause at a step, run `!sleep 60` in REPL
+   - Cancel the job from GitHub UI
+   - Verify: Sleep command terminates, DAP client receives terminated event, runner exits cleanly
+
+3. **Cancellation before debugger connects:**
+   - Start a debug job (it waits for connection)
+   - Cancel the job before connecting a debugger
+   - Verify: Runner exits cleanly (this already works, just verify no regression)
+
+4. **Normal operation (no cancellation):**
+   - Run through a debug session normally with step/continue
+   - Verify: No change in behavior
+
+5. **Debugger disconnect:**
+   - Connect debugger, then disconnect it manually
+   - Verify: Job continues to completion (existing behavior preserved)
+
+## Estimated Effort
+
+| Phase | Effort |
+|-------|--------|
+| Phase 1: Interface update | 15 min |
+| Phase 2: DapDebugSession implementation | 45 min |
+| Phase 3: StepsRunner update | 5 min |
+| Phase 4: JobRunner update | 15 min |

+# DAP Debug Logging Feature
+
+**Status:** Implemented  
+**Date:** January 2026  
+**Related:** [dap-debugging.md](./dap-debugging.md), [dap-step-backwards.md](./dap-step-backwards.md)
+
+## Overview
+
+Add comprehensive debug logging to the DAP debugging infrastructure that can be toggled from the DAP client. This helps diagnose issues like step conclusions not updating correctly after step-back operations.
+
+## Features
+
+### 1. Debug Log Levels
+
+| Level | Value | What Gets Logged |
+|-------|-------|------------------|
+| `Off` | 0 | Nothing |
+| `Minimal` | 1 | Errors, critical state changes |
+| `Normal` | 2 | Step lifecycle, checkpoint operations |
+| `Verbose` | 3 | Everything including outputs, expressions |
+
+### 2. Enabling Debug Logging
+
+#### Via Attach Arguments (nvim-dap config)
+
+```lua
+{
+  type = "runner",
+  request = "attach",
+  debugLogging = true,           -- Enable debug logging (defaults to "normal" level)
+  debugLogLevel = "verbose",     -- Optional: "off", "minimal", "normal", "verbose"
+}
+```
+
+#### Via REPL Commands (runtime toggle)
+
+| Command | Description |
+|---------|-------------|
+| `!debug on` | Enable debug logging (level: normal) |
+| `!debug off` | Disable debug logging |
+| `!debug minimal` | Set level to minimal |
+| `!debug normal` | Set level to normal |
+| `!debug verbose` | Set level to verbose |
+| `!debug status` | Show current debug settings |
+
+### 3. Log Output Format
+
+All debug logs are sent to the DAP console with the format:
+
+```
+[DEBUG] [Category] Message
+```
+
+Categories include:
+- `[Step]` - Step lifecycle events
+- `[Checkpoint]` - Checkpoint creation/restoration
+- `[StepsContext]` - Steps context mutations (SetOutcome, SetConclusion, SetOutput, ClearScope)
+
+### 4. Example Output
+
+With `!debug verbose` enabled:
+
+```
+[DEBUG] [Step] Starting: 'cat doesnotexist' (index=2)
+[DEBUG] [Step] Checkpoints available: 2
+[DEBUG] [StepsContext] SetOutcome: step='thecat', outcome=failure
+[DEBUG] [StepsContext] SetConclusion: step='thecat', conclusion=failure
+[DEBUG] [Step] Completed: 'cat doesnotexist', result=Failed
+[DEBUG] [Step] Context state: outcome=failure, conclusion=failure
+
+# After step-back:
+[DEBUG] [Checkpoint] Restoring checkpoint [1] for step 'cat doesnotexist'
+[DEBUG] [StepsContext] ClearScope: scope='(root)'
+[DEBUG] [StepsContext] Restoring: clearing scope '(root)', restoring 2 step(s)
+[DEBUG] [StepsContext] Restored: step='thefoo', outcome=success, conclusion=success
+
+# After re-running with file created:
+[DEBUG] [Step] Starting: 'cat doesnotexist' (index=2)
+[DEBUG] [StepsContext] SetOutcome: step='thecat', outcome=success
+[DEBUG] [StepsContext] SetConclusion: step='thecat', conclusion=success
+[DEBUG] [Step] Completed: 'cat doesnotexist', result=Succeeded
+[DEBUG] [Step] Context state: outcome=success, conclusion=success
+```
+

+
+---
+
+### Phase 1: Debug Logging Infrastructure
+
+**File:** `src/Runner.Worker/Dap/DapDebugSession.cs`
+
+Add enum and helper method:
+
+```csharp
+// Add enum for debug log levels (near top of file with other enums)
+public enum DebugLogLevel
+{
+    Off = 0,
+    Minimal = 1,    // Errors, critical state changes
+    Normal = 2,     // Step lifecycle, checkpoints
+    Verbose = 3     // Everything including outputs, expressions
+}
+
+// Add field (with other private fields)
+private DebugLogLevel _debugLogLevel = DebugLogLevel.Off;
+
+// Add helper method (in a #region Debug Logging)
+private void DebugLog(string message, DebugLogLevel minLevel = DebugLogLevel.Normal)
+{
+    if (_debugLogLevel >= minLevel)
+    {
+        _server?.SendEvent(new Event
+        {
+            EventType = "output",
+            Body = new OutputEventBody
+            {
+                Category = "console",
+                Output = $"[DEBUG] {message}\n"
+            }
+        });
+    }
+}
+```
+
+Update `HandleAttach` to parse debug logging arguments:
+
+```csharp
+private Response HandleAttach(Request request)
+{
+    Trace.Info("Attach request handled");
+
+    // Parse debug logging from attach args
+    if (request.Arguments is JsonElement args)
+    {
+        if (args.TryGetProperty("debugLogging", out var debugLogging))
+        {
+            if (debugLogging.ValueKind == JsonValueKind.True)
+            {
+                _debugLogLevel = DebugLogLevel.Normal;
+                Trace.Info("Debug logging enabled via attach args (level: normal)");
+            }
+        }
+        if (args.TryGetProperty("debugLogLevel", out var level) && level.ValueKind == JsonValueKind.String)
+        {
+            _debugLogLevel = level.GetString()?.ToLower() switch
+            {
+                "minimal" => DebugLogLevel.Minimal,
+                "normal" => DebugLogLevel.Normal,
+                "verbose" => DebugLogLevel.Verbose,
+                "off" => DebugLogLevel.Off,
+                _ => _debugLogLevel
+            };
+            Trace.Info($"Debug log level set via attach args: {_debugLogLevel}");
+        }
+    }
+
+    return CreateSuccessResponse(null);
+}
+```
+
+---
+
+### Phase 2: REPL `!debug` Command
+
+**File:** `src/Runner.Worker/Dap/DapDebugSession.cs`
+
+In `HandleEvaluateAsync`, add handling for `!debug` command before other shell command handling:
+
+```csharp
+// Near the start of HandleEvaluateAsync, after getting the expression:
+
+// Check for debug command
+if (expression.StartsWith("!debug", StringComparison.OrdinalIgnoreCase))
+{
+    return HandleDebugCommand(expression);
+}
+
+// ... rest of existing HandleEvaluateAsync code
+```
+
+Add the handler method:
+
+```csharp
+private Response HandleDebugCommand(string command)
+{
+    var parts = command.Split(' ', StringSplitOptions.RemoveEmptyEntries);
+    var arg = parts.Length > 1 ? parts[1].ToLower() : "status";
+    
+    string result;
+    switch (arg)
+    {
+        case "on":
+            _debugLogLevel = DebugLogLevel.Normal;
+            result = "Debug logging enabled (level: normal)";
+            break;
+        case "off":
+            _debugLogLevel = DebugLogLevel.Off;
+            result = "Debug logging disabled";
+            break;
+        case "minimal":
+            _debugLogLevel = DebugLogLevel.Minimal;
+            result = "Debug logging set to minimal";
+            break;
+        case "normal":
+            _debugLogLevel = DebugLogLevel.Normal;
+            result = "Debug logging set to normal";
+            break;
+        case "verbose":
+            _debugLogLevel = DebugLogLevel.Verbose;
+            result = "Debug logging set to verbose";
+            break;
+        case "status":
+        default:
+            result = $"Debug logging: {_debugLogLevel}";
+            break;
+    }
+
+    return CreateSuccessResponse(new EvaluateResponseBody
+    {
+        Result = result,
+        VariablesReference = 0
+    });
+}
+```
+
+---
+
+### Phase 3: StepsContext OnDebugLog Callback
+
+**File:** `src/Runner.Worker/StepsContext.cs`
+
+Add callback property and helper:
+
+```csharp
+public sealed class StepsContext
+{
+    private static readonly Regex _propertyRegex = new("^[a-zA-Z_][a-zA-Z0-9_]*$", RegexOptions.Compiled);
+    private readonly DictionaryContextData _contextData = new();
+
+    /// <summary>
+    /// Optional callback for debug logging. When set, will be called with debug messages
+    /// for all StepsContext mutations.
+    /// </summary>
+    public Action<string> OnDebugLog { get; set; }
+
+    private void DebugLog(string message)
+    {
+        OnDebugLog?.Invoke(message);
+    }
+
+    // ... rest of class
+}
+```
+
+Update `ClearScope`:
+
+```csharp
+public void ClearScope(string scopeName)
+{
+    DebugLog($"[StepsContext] ClearScope: scope='{scopeName ?? "(root)"}'");
+    if (_contextData.TryGetValue(scopeName, out _))
+    {
+        _contextData[scopeName] = new DictionaryContextData();
+    }
+}
+```
+
+Update `SetOutput`:
+
+```csharp
+public void SetOutput(
+    string scopeName,
+    string stepName,
+    string outputName,
+    string value,
+    out string reference)
+{
+    var step = GetStep(scopeName, stepName);
+    var outputs = step["outputs"].AssertDictionary("outputs");
+    outputs[outputName] = new StringContextData(value);
+    if (_propertyRegex.IsMatch(outputName))
+    {
+        reference = $"steps.{stepName}.outputs.{outputName}";
+    }
+    else
+    {
+        reference = $"steps['{stepName}']['outputs']['{outputName}']";
+    }
+    DebugLog($"[StepsContext] SetOutput: step='{stepName}', output='{outputName}', value='{TruncateValue(value)}'");
+}
+
+private static string TruncateValue(string value, int maxLength = 50)
+{
+    if (string.IsNullOrEmpty(value)) return "(empty)";
+    if (value.Length <= maxLength) return value;
+    return value.Substring(0, maxLength) + "...";
+}
+```
+
+Update `SetConclusion`:
+
+```csharp
+public void SetConclusion(
+    string scopeName,
+    string stepName,
+    ActionResult conclusion)
+{
+    var step = GetStep(scopeName, stepName);
+    var conclusionStr = conclusion.ToString().ToLowerInvariant();
+    step["conclusion"] = new StringContextData(conclusionStr);
+    DebugLog($"[StepsContext] SetConclusion: step='{stepName}', conclusion={conclusionStr}");
+}
+```
+
+Update `SetOutcome`:
+
+```csharp
+public void SetOutcome(
+    string scopeName,
+    string stepName,
+    ActionResult outcome)
+{
+    var step = GetStep(scopeName, stepName);
+    var outcomeStr = outcome.ToString().ToLowerInvariant();
+    step["outcome"] = new StringContextData(outcomeStr);
+    DebugLog($"[StepsContext] SetOutcome: step='{stepName}', outcome={outcomeStr}");
+}
+```
+
+---
+
+### Phase 4: DapDebugSession Logging Calls
+
+**File:** `src/Runner.Worker/Dap/DapDebugSession.cs`
+
+#### In `OnStepStartingAsync` (after setting `_currentStep` and `_jobContext`):
+
+```csharp
+DebugLog($"[Step] Starting: '{step.DisplayName}' (index={stepIndex})");
+DebugLog($"[Step] Checkpoints available: {_checkpoints.Count}");
+```
+
+#### In `OnStepCompleted` (after logging to Trace):
+
+```csharp
+DebugLog($"[Step] Completed: '{step.DisplayName}', result={result}");
+
+// Log current steps context state for this step
+if (_debugLogLevel >= DebugLogLevel.Normal)
+{
+    var stepsScope = step.ExecutionContext?.Global?.StepsContext?.GetScope(step.ExecutionContext.ScopeName);
+    if (stepsScope != null && !string.IsNullOrEmpty(step.ExecutionContext?.ContextName))
+    {
+        if (stepsScope.TryGetValue(step.ExecutionContext.ContextName, out var stepData) && stepData is DictionaryContextData sd)
+        {
+            var outcome = sd.TryGetValue("outcome", out var o) && o is StringContextData os ? os.Value : "null";
+            var conclusion = sd.TryGetValue("conclusion", out var c) && c is StringContextData cs ? cs.Value : "null";
+            DebugLog($"[Step] Context state: outcome={outcome}, conclusion={conclusion}");
+        }
+    }
+}
+```
+
+#### In `CreateCheckpointForPendingStep` (after creating checkpoint):
+
+```csharp
+DebugLog($"[Checkpoint] Created [{_checkpoints.Count - 1}] for step '{_pendingStep.DisplayName}'");
+if (_debugLogLevel >= DebugLogLevel.Verbose)
+{
+    DebugLog($"[Checkpoint] Snapshot contains {checkpoint.StepsSnapshot.Count} step(s)", DebugLogLevel.Verbose);
+    foreach (var entry in checkpoint.StepsSnapshot)
+    {
+        DebugLog($"[Checkpoint]   {entry.Key}: outcome={entry.Value.Outcome}, conclusion={entry.Value.Conclusion}", DebugLogLevel.Verbose);
+    }
+}
+```
+
+#### In `RestoreCheckpoint` (at start of method):
+
+```csharp
+DebugLog($"[Checkpoint] Restoring [{checkpointIndex}] for step '{checkpoint.StepDisplayName}'");
+if (_debugLogLevel >= DebugLogLevel.Verbose)
+{
+    DebugLog($"[Checkpoint] Snapshot has {checkpoint.StepsSnapshot.Count} step(s)", DebugLogLevel.Verbose);
+}
+```
+
+#### In `RestoreStepsContext` (update existing method):
+
+```csharp
+private void RestoreStepsContext(StepsContext stepsContext, Dictionary<string, StepStateSnapshot> snapshot, string scopeName)
+{
+    scopeName = scopeName ?? string.Empty;
+
+    DebugLog($"[StepsContext] Restoring: clearing scope '{(string.IsNullOrEmpty(scopeName) ? "(root)" : scopeName)}', will restore {snapshot.Count} step(s)");
+
+    stepsContext.ClearScope(scopeName);
+
+    foreach (var entry in snapshot)
+    {
+        var key = entry.Key;
+        var slashIndex = key.IndexOf('/');
+
+        if (slashIndex >= 0)
+        {
+            var snapshotScopeName = slashIndex > 0 ? key.Substring(0, slashIndex) : string.Empty;
+            var stepName = key.Substring(slashIndex + 1);
+
+            if (snapshotScopeName == scopeName)
+            {
+                var state = entry.Value;
+
+                if (state.Outcome.HasValue)
+                {
+                    stepsContext.SetOutcome(scopeName, stepName, state.Outcome.Value);
+                }
+                if (state.Conclusion.HasValue)
+                {
+                    stepsContext.SetConclusion(scopeName, stepName, state.Conclusion.Value);
+                }
+
+                if (state.Outputs != null)
+                {
+                    foreach (var output in state.Outputs)
+                    {
+                        stepsContext.SetOutput(scopeName, stepName, output.Key, output.Value, out _);
+                    }
+                }
+
+                DebugLog($"[StepsContext] Restored: step='{stepName}', outcome={state.Outcome}, conclusion={state.Conclusion}", DebugLogLevel.Verbose);
+            }
+        }
+    }
+
+    Trace.Info($"Steps context restored: cleared scope '{scopeName}' and restored {snapshot.Count} step(s) from snapshot");
+}
+```
+
+---
+
+### Phase 5: Hook Up StepsContext Logging
+
+**File:** `src/Runner.Worker/Dap/DapDebugSession.cs`
+
+In `OnStepStartingAsync`, after setting `_jobContext`, hook up the callback (only once):
+
+```csharp
+// Hook up StepsContext debug logging (do this once when we first get jobContext)
+if (jobContext.Global.StepsContext.OnDebugLog == null)
+{
+    jobContext.Global.StepsContext.OnDebugLog = (msg) => DebugLog(msg, DebugLogLevel.Verbose);
+}
+```
+
+**Note:** StepsContext logging is set to `Verbose` level since `SetOutput` can be noisy. `SetConclusion` and `SetOutcome` will still appear at `Verbose` level, but all the important state changes are also logged directly in `OnStepCompleted` at `Normal` level.
+
+---
+
+### Phase 6: Testing
+
+#### Manual Testing Checklist
+
+- [ ] `!debug status` shows "Off" by default
+- [ ] `!debug on` enables logging, shows step lifecycle
+- [ ] `!debug verbose` shows StepsContext mutations
+- [ ] `!debug off` disables logging
+- [ ] Attach with `debugLogging: true` enables logging on connect
+- [ ] Attach with `debugLogLevel: "verbose"` sets correct level
+- [ ] Step-back scenario shows restoration logs
+- [ ] Logs help identify why conclusion might not update
+
+#### Test Workflow
+
+Use the test workflow with `thecat` step:
+1. Run workflow, let `thecat` fail
+2. Enable `!debug verbose`
+3. Step back
+4. Create the missing file
+5. Step forward
+6. Observe logs to see if `SetConclusion` is called with `success`
+
+---

+# DAP Debugging - Bug Fixes and Enhancements
+
+**Status:** Planned  
+**Date:** January 2026  
+**Related:** [dap-debugging.md](./dap-debugging.md)
+
+## Overview
+
+This document tracks bug fixes and enhancements for the DAP debugging implementation after the initial phases were completed.
+
+## Issues
+
+### Bug 1: Double Output in REPL Shell Commands
+
+**Symptom:** Running commands in the REPL shell produces double output - the first one unmasked, the second one with secrets masked.
+
+**Root Cause:** In `DapDebugSession.ExecuteShellCommandAsync()` (lines 670-773), output is sent to the debugger twice:
+
+1. **Real-time streaming (unmasked):** Lines 678-712 stream output via DAP `output` events as data arrives from the process - but this output is NOT masked
+2. **Final result (masked):** Lines 765-769 return the combined output as `EvaluateResponseBody.Result` with secrets masked
+
+The DAP client displays both the streamed events AND the evaluate response result, causing duplication.
+
+**Fix:**
+1. Mask secrets in the real-time streaming output (add `HostContext.SecretMasker.MaskSecrets()` to lines ~690 and ~708)
+2. Change the final `Result` to only show exit code summary instead of full output
+
+---
+
+### Bug 2: Expressions Interpreted as Shell Commands
+
+**Symptom:** Evaluating expressions like `${{github.event_name}} == 'push'` in the Watch/Expressions pane results in them being executed as shell commands instead of being evaluated as GitHub Actions expressions.
+
+**Root Cause:** In `DapDebugSession.HandleEvaluateAsync()` (line 514), the condition to detect shell commands is too broad:
+
+```csharp
+if (evalContext == "repl" || expression.StartsWith("!") || expression.StartsWith("$"))
+```
+
+Since `${{github.event_name}}` starts with `$`, it gets routed to shell execution instead of expression evaluation.
+
+**Fix:**
+1. Check for `${{` prefix first - these are always GitHub Actions expressions
+2. Remove the `expression.StartsWith("$")` condition entirely (ambiguous and unnecessary since REPL context handles shell commands)
+3. Keep `expression.StartsWith("!")` for explicit shell override in non-REPL contexts
+
+---
+
+### Enhancement: Expression Interpolation in REPL Commands
+
+**Request:** When running REPL commands like `echo ${{github.event_name}}`, the `${{ }}` expressions should be expanded before shell execution, similar to how `run:` steps work.
+
+**Approach:** Add a helper method that uses the existing `PipelineTemplateEvaluator` infrastructure to expand expressions in the command string before passing it to the shell.
+
+---
+
+## Implementation Details
+
+### File: `src/Runner.Worker/Dap/DapDebugSession.cs`
+
+#### Change 1: Mask Real-Time Streaming Output
+
+**Location:** Lines ~678-712 (OutputDataReceived and ErrorDataReceived handlers)
+
+**Before:**
+```csharp
+processInvoker.OutputDataReceived += (sender, args) =>
+{
+    if (!string.IsNullOrEmpty(args.Data))
+    {
+        output.AppendLine(args.Data);
+        _server?.SendEvent(new Event
+        {
+            EventType = "output",
+            Body = new OutputEventBody
+            {
+                Category = "stdout",
+                Output = args.Data + "\n"  // NOT MASKED
+            }
+        });
+    }
+};
+```
+
+**After:**
+```csharp
+processInvoker.OutputDataReceived += (sender, args) =>
+{
+    if (!string.IsNullOrEmpty(args.Data))
+    {
+        output.AppendLine(args.Data);
+        var maskedData = HostContext.SecretMasker.MaskSecrets(args.Data);
+        _server?.SendEvent(new Event
+        {
+            EventType = "output",
+            Body = new OutputEventBody
+            {
+                Category = "stdout",
+                Output = maskedData + "\n"
+            }
+        });
+    }
+};
+```
+
+Apply the same change to `ErrorDataReceived` handler (~lines 696-712).
+
+---
+
+#### Change 2: Return Only Exit Code in Result
+
+**Location:** Lines ~767-772 (return statement in ExecuteShellCommandAsync)
+
+**Before:**
+```csharp
+return new EvaluateResponseBody
+{
+    Result = result.TrimEnd('\r', '\n'),
+    Type = exitCode == 0 ? "string" : "error",
+    VariablesReference = 0
+};
+```
+
+**After:**
+```csharp
+return new EvaluateResponseBody
+{
+    Result = $"(exit code: {exitCode})",
+    Type = exitCode == 0 ? "string" : "error",
+    VariablesReference = 0
+};
+```
+
+Also remove the result combination logic (lines ~747-762) since we no longer need to build the full result string for the response.
+
+---
+
+#### Change 3: Fix Expression vs Shell Routing
+
+**Location:** Lines ~511-536 (HandleEvaluateAsync method)
+
+**Before:**
+```csharp
+try
+{
+    // Check if this is a REPL/shell command (context: "repl") or starts with shell prefix
+    if (evalContext == "repl" || expression.StartsWith("!") || expression.StartsWith("$"))
+    {
+        // Shell execution mode
+        var command = expression.TrimStart('!', '$').Trim();
+        // ...
+    }
+    else
+    {
+        // Expression evaluation mode
+        var result = EvaluateExpression(expression, executionContext);
+        return CreateSuccessResponse(result);
+    }
+}
+```
+
+**After:**
+```csharp
+try
+{
+    // GitHub Actions expressions start with "${{" - always evaluate as expressions
+    if (expression.StartsWith("${{"))
+    {
+        var result = EvaluateExpression(expression, executionContext);
+        return CreateSuccessResponse(result);
+    }
+
+    // Check if this is a REPL/shell command:
+    // - context is "repl" (from Debug Console pane)
+    // - expression starts with "!" (explicit shell prefix for Watch pane)
+    if (evalContext == "repl" || expression.StartsWith("!"))
+    {
+        // Shell execution mode
+        var command = expression.TrimStart('!').Trim();
+        if (string.IsNullOrEmpty(command))
+        {
+            return CreateSuccessResponse(new EvaluateResponseBody
+            {
+                Result = "(empty command)",
+                Type = "string",
+                VariablesReference = 0
+            });
+        }
+
+        var result = await ExecuteShellCommandAsync(command, executionContext);
+        return CreateSuccessResponse(result);
+    }
+    else
+    {
+        // Expression evaluation mode (Watch pane, hover, etc.)
+        var result = EvaluateExpression(expression, executionContext);
+        return CreateSuccessResponse(result);
+    }
+}
+```
+
+---
+
+#### Change 4: Add Expression Expansion Helper Method
+
+**Location:** Add new method before `ExecuteShellCommandAsync` (~line 667)
+
+```csharp
+/// <summary>
+/// Expands ${{ }} expressions within a command string.
+/// For example: "echo ${{github.event_name}}" -> "echo push"
+/// </summary>
+private string ExpandExpressionsInCommand(string command, IExecutionContext context)
+{
+    if (string.IsNullOrEmpty(command) || !command.Contains("${{"))
+    {
+        return command;
+    }
+
+    try
+    {
+        // Create a StringToken with the command
+        var token = new StringToken(null, null, null, command);
+
+        // Use the template evaluator to expand expressions
+        var templateEvaluator = context.ToPipelineTemplateEvaluator();
+        var result = templateEvaluator.EvaluateStepDisplayName(
+            token,
+            context.ExpressionValues,
+            context.ExpressionFunctions);
+
+        // Mask secrets in the expanded command
+        result = HostContext.SecretMasker.MaskSecrets(result ?? command);
+
+        Trace.Info($"Expanded command: {result}");
+        return result;
+    }
+    catch (Exception ex)
+    {
+        Trace.Info($"Expression expansion failed, using original command: {ex.Message}");
+        return command;
+    }
+}
+```
+
+**Required import:** Add `using GitHub.DistributedTask.ObjectTemplating.Tokens;` at the top of the file if not already present.
+
+---
+
+#### Change 5: Use Expression Expansion in Shell Execution
+
+**Location:** Beginning of `ExecuteShellCommandAsync` method (~line 670)
+
+**Before:**
+```csharp
+private async Task<EvaluateResponseBody> ExecuteShellCommandAsync(string command, IExecutionContext context)
+{
+    Trace.Info($"Executing shell command: {command}");
+    // ...
+}
+```
+
+**After:**
+```csharp
+private async Task<EvaluateResponseBody> ExecuteShellCommandAsync(string command, IExecutionContext context)
+{
+    // Expand ${{ }} expressions in the command first
+    command = ExpandExpressionsInCommand(command, context);
+
+    Trace.Info($"Executing shell command: {command}");
+    // ...
+}
+```
+
+---
+
+## DAP Context Reference
+
+For future reference, these are the DAP evaluate context values:
+
+| DAP Context | Source UI | Behavior |
+|-------------|-----------|----------|
+| `"repl"` | Debug Console / REPL pane | Shell execution (with expression expansion) |
+| `"watch"` | Watch / Expressions pane | Expression evaluation |
+| `"hover"` | Editor hover (default) | Expression evaluation |
+| `"variables"` | Variables pane | Expression evaluation |
+| `"clipboard"` | Copy to clipboard | Expression evaluation |
+
+---
+
+## Testing Checklist
+
+- [ ] REPL command output is masked and appears only once
+- [ ] REPL command shows exit code in result field
+- [ ] Expression `${{github.event_name}}` evaluates correctly in Watch pane
+- [ ] Expression `${{github.event_name}} == 'push'` evaluates correctly
+- [ ] REPL command `echo ${{github.event_name}}` expands and executes correctly
+- [ ] REPL command `!ls -la` from Watch pane works (explicit shell prefix)
+- [ ] Secrets are masked in all outputs (streaming and expanded commands)

+# DAP-Based Debugging for GitHub Actions Runner
+
+**Status:** Draft  
+**Author:** GitHub Actions Team  
+**Date:** January 2026
+
+## Progress Checklist
+
+- [x] **Phase 1:** DAP Protocol Infrastructure (DapMessages.cs, DapServer.cs, basic DapDebugSession.cs)
+- [x] **Phase 2:** Debug Session Logic (DapVariableProvider.cs, variable inspection, step history tracking)
+- [x] **Phase 3:** StepsRunner Integration (pause hooks before/after step execution)
+- [x] **Phase 4:** Expression Evaluation & Shell (REPL)
+- [x] **Phase 5:** Startup Integration (JobRunner.cs modifications)
+
+## Overview
+
+This document describes the implementation of Debug Adapter Protocol (DAP) support in the GitHub Actions runner, enabling rich debugging of workflow jobs from any DAP-compatible editor (nvim-dap, VS Code, etc.).
+
+## Goals
+
+- **Primary:** Create a working demo to demonstrate the feasibility of DAP-based workflow debugging
+- **Non-goal:** Production-ready, polished implementation (this is proof-of-concept)
+
+## User Experience
+
+1. User re-runs a failed job with "Enable debug logging" checked in GitHub UI
+2. Runner (running locally) detects debug mode and starts DAP server on port 4711
+3. Runner prints "Waiting for debugger on port 4711..." and pauses
+4. User opens editor (nvim with nvim-dap), connects to debugger
+5. Job execution begins, pausing before the first step
+6. User can:
+   - **Inspect variables:** View `github`, `env`, `inputs`, `steps`, `secrets` (redacted), `runner`, `job` contexts
+   - **Evaluate expressions:** `${{ github.event.pull_request.title }}`
+   - **Execute shell commands:** Run arbitrary commands in the job's environment (REPL)
+   - **Step through job:** `next` moves to next step, `continue` runs to end
+   - **Pause after steps:** Inspect step outputs before continuing
+
+## Activation
+
+DAP debugging activates automatically when the job is in debug mode:
+
+- User enables "Enable debug logging" when re-running a job in GitHub UI
+- Server sends `ACTIONS_STEP_DEBUG=true` in job variables
+- Runner sets `Global.WriteDebug = true` and `runner.debug = "1"`
+- DAP server starts on port 4711
+
+**No additional configuration required.**
+
+### Optional Configuration
+
+| Environment Variable | Default | Description |
+|---------------------|---------|-------------|
+| `ACTIONS_DAP_PORT` | `4711` | TCP port for DAP server (optional override) |

+## DAP Concept Mapping
+
+| DAP Concept | Actions Runner Equivalent |
+|-------------|---------------------------|
+| Thread | Single job execution |
+| Stack Frame | Current step + completed steps (step history) |
+| Scope | Context category: `github`, `env`, `inputs`, `steps`, `secrets`, `runner`, `job` |
+| Variable | Individual context values |
+| Breakpoint | Pause before specific step (future enhancement) |
+| Step Over (Next) | Execute current step, pause before next |
+| Continue | Run until job end |
+| Evaluate | Evaluate `${{ }}` expressions OR execute shell commands (REPL) |

+│   └── DapVariableProvider.cs    # Converts ExecutionContext to DAP variables
+```
+
+## Implementation Phases
+
+### Phase 1: DAP Protocol Infrastructure
+
+#### 1.1 Protocol Messages (`Dap/DapMessages.cs`)
+
+Base message types following DAP spec:
+
+```csharp
+public abstract class ProtocolMessage
+{
+    public int seq { get; set; }
+    public string type { get; set; }  // "request", "response", "event"
+}
+
+public class Request : ProtocolMessage
+{
+    public string command { get; set; }
+    public object arguments { get; set; }
+}
+
+public class Response : ProtocolMessage
+{
+    public int request_seq { get; set; }
+    public bool success { get; set; }
+    public string command { get; set; }
+    public string message { get; set; }
+    public object body { get; set; }
+}
+
+public class Event : ProtocolMessage
+{
+    public string @event { get; set; }
+    public object body { get; set; }
+}
+```
+
+Message framing: `Content-Length: N\r\n\r\n{json}`
+
+#### 1.2 DAP Server (`Dap/DapServer.cs`)
+
+```csharp
+[ServiceLocator(Default = typeof(DapServer))]
+public interface IDapServer : IRunnerService
+{
+    Task StartAsync(int port);
+    Task WaitForConnectionAsync();
+    Task StopAsync();
+    void SendEvent(Event evt);
+}
+
+public sealed class DapServer : RunnerService, IDapServer
+{
+    private TcpListener _listener;
+    private TcpClient _client;
+    private IDapDebugSession _session;
+    
+    // TCP listener on configurable port
+    // Single-client connection
+    // Async read/write loop
+    // Dispatch requests to DapDebugSession
+}
+```
+
+### Phase 2: Debug Session Logic
+
+#### 2.1 Debug Session (`Dap/DapDebugSession.cs`)
+
+```csharp
+public enum DapCommand { Continue, Next, Pause, Disconnect }
+public enum PauseReason { Entry, Step, Breakpoint, Pause }
+
+[ServiceLocator(Default = typeof(DapDebugSession))]
+public interface IDapDebugSession : IRunnerService
+{
+    bool IsActive { get; }
+    
+    // Called by DapServer
+    void Initialize(InitializeRequestArguments args);
+    void Attach(AttachRequestArguments args);
+    void ConfigurationDone();
+    Task<DapCommand> WaitForCommandAsync();
+    
+    // Called by StepsRunner
+    Task OnStepStartingAsync(IStep step, IExecutionContext jobContext);
+    void OnStepCompleted(IStep step);
+    
+    // DAP requests
+    ThreadsResponse GetThreads();
+    StackTraceResponse GetStackTrace(int threadId);
+    ScopesResponse GetScopes(int frameId);
+    VariablesResponse GetVariables(int variablesReference);
+    EvaluateResponse Evaluate(string expression, string context);
+}
+
+public sealed class DapDebugSession : RunnerService, IDapDebugSession
+{
+    private IExecutionContext _jobContext;
+    private IStep _currentStep;
+    private readonly List<IStep> _completedSteps = new();
+    private TaskCompletionSource<DapCommand> _commandTcs;
+    private bool _pauseAfterStep = false;
+    
+    // Object reference management for nested variables
+    private int _nextVariableReference = 1;
+    private readonly Dictionary<int, object> _variableReferences = new();
+}
+```
+
+Core state machine:
+1. **Waiting for client:** Server started, no client connected
+2. **Initializing:** Client connected, exchanging capabilities
+3. **Ready:** `configurationDone` received, waiting to start
+4. **Paused (before step):** Stopped before step execution, waiting for command
+5. **Running:** Executing a step
+6. **Paused (after step):** Stopped after step execution, waiting for command
+
+#### 2.2 Variable Provider (`Dap/DapVariableProvider.cs`)
+
+Maps `ExecutionContext.ExpressionValues` to DAP scopes and variables:
+
+| Scope | Source | Notes |
+|-------|--------|-------|
+| `github` | `ExpressionValues["github"]` | Full github context |
+| `env` | `ExpressionValues["env"]` | Environment variables |
+| `inputs` | `ExpressionValues["inputs"]` | Step inputs (when available) |
+| `steps` | `Global.StepsContext.GetScope()` | Completed step outputs |
+| `secrets` | `ExpressionValues["secrets"]` | Keys shown, values = `[REDACTED]` |
+| `runner` | `ExpressionValues["runner"]` | Runner context |
+| `job` | `ExpressionValues["job"]` | Job status |
+
+Nested objects (e.g., `github.event.pull_request`) become expandable variables with child references.
+
+### Phase 3: StepsRunner Integration
+
+#### 3.1 Modify `StepsRunner.cs`
+
+Add debug hooks at step boundaries:
+
+```csharp
+public async Task RunAsync(IExecutionContext jobContext)
+{
+    // Get debug session if available
+    var debugSession = HostContext.TryGetService<IDapDebugSession>();
+    bool isFirstStep = true;
+    
+    while (jobContext.JobSteps.Count > 0 || !checkPostJobActions)
+    {
+        // ... existing dequeue logic ...
+        
+        var step = jobContext.JobSteps.Dequeue();
+        
+        // Pause BEFORE step execution
+        if (debugSession?.IsActive == true)
+        {
+            var reason = isFirstStep ? PauseReason.Entry : PauseReason.Step;
+            await debugSession.OnStepStartingAsync(step, jobContext, reason);
+            isFirstStep = false;
+        }
+        
+        // ... existing step execution (condition eval, RunStepAsync, etc.) ...
+        
+        // Pause AFTER step execution (if requested)
+        if (debugSession?.IsActive == true)
+        {
+            debugSession.OnStepCompleted(step);
+            // Session may pause here to let user inspect outputs
+        }
+    }
+}
+```
+
+### Phase 4: Expression Evaluation & Shell (REPL)
+
+#### 4.1 Expression Evaluation
+
+Reuse existing `PipelineTemplateEvaluator`:
+
+```csharp
+private EvaluateResponseBody EvaluateExpression(string expression, IExecutionContext context)
+{
+    // Strip ${{ }} wrapper if present
+    var expr = expression.Trim();
+    if (expr.StartsWith("${{") && expr.EndsWith("}}"))
+    {
+        expr = expr.Substring(3, expr.Length - 5).Trim();
+    }
+    
+    var expressionToken = new BasicExpressionToken(fileId: null, line: null, column: null, expression: expr);
+    var templateEvaluator = context.ToPipelineTemplateEvaluator();
+    
+    var result = templateEvaluator.EvaluateStepDisplayName(
+        expressionToken, 
+        context.ExpressionValues, 
+        context.ExpressionFunctions
+    );
+    
+    // Mask secrets and determine type
+    result = HostContext.SecretMasker.MaskSecrets(result ?? "null");
+    
+    return new EvaluateResponseBody
+    {
+        Result = result,
+        Type = DetermineResultType(result),
+        VariablesReference = 0
+    };
+}
+```
+
+**Supported expression formats:**
+- Plain expression: `github.ref`, `steps.build.outputs.result`
+- Wrapped expression: `${{ github.event.pull_request.title }}`
+
+#### 4.2 Shell Execution (REPL)
+
+Shell execution is triggered when:
+1. The evaluate request has `context: "repl"`, OR
+2. The expression starts with `!` (e.g., `!ls -la`), OR  
+3. The expression starts with `$` followed by a shell command (e.g., `$env`)
+
+**Usage examples in debug console:**
+```
+!ls -la                          # List files in workspace
+!env | grep GITHUB               # Show GitHub environment variables
+!cat $GITHUB_EVENT_PATH          # View the event payload
+!echo ${{ github.ref }}          # Mix shell and expression (evaluated first)
+```
+
+**Implementation:**
+
+```csharp
+private async Task<EvaluateResponseBody> ExecuteShellCommandAsync(string command, IExecutionContext context)
+{
+    var processInvoker = HostContext.CreateService<IProcessInvoker>();
+    var output = new StringBuilder();
+    
+    processInvoker.OutputDataReceived += (sender, args) =>
+    {
+        output.AppendLine(args.Data);
+        // Stream to client in real-time via DAP output event
+        _server?.SendEvent(new Event
+        {
+            EventType = "output",
+            Body = new OutputEventBody { Category = "stdout", Output = args.Data + "\n" }
+        });
+    };
+    
+    processInvoker.ErrorDataReceived += (sender, args) =>
+    {
+        _server?.SendEvent(new Event
+        {
+            EventType = "output",
+            Body = new OutputEventBody { Category = "stderr", Output = args.Data + "\n" }
+        });
+    };
+

+
+**Shell detection by platform:**
+
+| Platform | Priority | Shell | Arguments |
+|----------|----------|-------|-----------|
+| Windows | 1 | `pwsh` | `-NoProfile -NonInteractive -Command "{0}"` |
+| Windows | 2 | `powershell` | `-NoProfile -NonInteractive -Command "{0}"` |
+| Windows | 3 | `cmd.exe` | `/C "{0}"` |
+| Unix | 1 | `bash` | `-c "{0}"` |
+| Unix | 2 | `sh` | `-c "{0}"` |
+
+**Environment built for shell commands:**
+- Current system environment variables
+- GitHub Actions context variables (from `IEnvironmentContextData.GetRuntimeEnvironmentVariables()`)
+- Prepend path from job context added to `PATH`
+
+### Phase 5: Startup Integration
+
+#### 5.1 Modify `JobRunner.cs`
+
+Add DAP server startup after debug mode is detected (around line 159):
+
+```csharp
+if (jobContext.Global.WriteDebug)
+{
+    jobContext.SetRunnerContext("debug", "1");
+    
+    // Start DAP server for interactive debugging
+    var dapServer = HostContext.GetService<IDapServer>();
+    var port = int.Parse(
+        Environment.GetEnvironmentVariable("ACTIONS_DAP_PORT") ?? "4711");
+    
+    await dapServer.StartAsync(port);
+    Trace.Info($"DAP server listening on port {port}");
+    jobContext.Output($"DAP debugger waiting for connection on port {port}...");
+    
+    // Block until debugger connects
+    await dapServer.WaitForConnectionAsync();
+    Trace.Info("DAP client connected, continuing job execution");
+}
+```
+
+## DAP Capabilities
+
+Capabilities to advertise in `InitializeResponse`:
+
+```json
+{
+    "supportsConfigurationDoneRequest": true,
+    "supportsEvaluateForHovers": true,
+    "supportsTerminateDebuggee": true,
+    "supportsStepBack": false,
+    "supportsSetVariable": false,
+    "supportsRestartFrame": false,

+    "supportsLoadedSourcesRequest": false,
+    "supportsProgressReporting": false,
+    "supportsRunInTerminalRequest": false
+}
+```
+
+## Client Configuration (nvim-dap)
+
+Example configuration for nvim-dap:
+
+```lua
+local dap = require('dap')
+
+dap.adapters.actions = {
+    type = 'server',
+    host = '127.0.0.1',
+    port = 4711,
+}
+
+dap.configurations.yaml = {
+    {
+        type = 'actions',
+        request = 'attach',
+        name = 'Attach to Actions Runner',
+    }
+}
+```
+
+## Demo Flow
+
+1. Trigger job re-run with "Enable debug logging" checked in GitHub UI
+2. Runner starts, detects debug mode (`Global.WriteDebug == true`)
+3. DAP server starts, console shows: `DAP debugger waiting for connection on port 4711...`
+4. In nvim: `:lua require('dap').continue()`
+5. Connection established, capabilities exchanged
+6. Job begins, pauses before first step
+7. nvim shows "stopped" state, variables panel shows contexts
+8. User explores variables, evaluates expressions, runs shell commands
+9. User presses `n` (next) to advance to next step
+10. After step completes, user can inspect outputs before continuing
+11. Repeat until job completes
+
+## Testing Strategy
+
+1. **Unit tests:** DAP protocol serialization, variable provider mapping
+2. **Integration tests:** Mock DAP client verifying request/response sequences
+3. **Manual testing:** Real job with nvim-dap attached
+
+## Future Enhancements (Out of Scope for Demo)
+
+- Composite action step-in (expand into sub-steps)
+- Breakpoints on specific step names
+- Watch expressions
+- Conditional breakpoints
+- Remote debugging (runner not on localhost)
+- VS Code extension
+

+# Actions DAP Debugger - Browser Extension
+
+A Chrome extension that enables interactive debugging of GitHub Actions workflows directly in the browser. Connects to the runner's DAP server via a WebSocket proxy.
+
+## Features
+
+- **Variable Inspection**: Browse workflow context variables (`github`, `env`, `steps`, etc.)
+- **REPL Console**: Evaluate expressions and run shell commands
+- **Step Control**: Step forward, step back, continue, and reverse continue
+- **GitHub Integration**: Debugger pane injects directly into the job page
+
+## Quick Start
+
+### 1. Start the WebSocket Proxy
+
+The proxy bridges WebSocket connections from the browser to the DAP TCP server.
+
+```bash
+cd browser-ext/proxy
+npm install
+node proxy.js
+```
+
+The proxy listens on `ws://localhost:4712` and connects to the DAP server at `tcp://localhost:4711`.
+
+### 2. Load the Extension in Chrome
+
+1. Open Chrome and navigate to `chrome://extensions/`
+2. Enable "Developer mode" (toggle in top right)
+3. Click "Load unpacked"
+4. Select the `browser-ext` directory
+
+### 3. Start a Debug Session
+
+1. Go to your GitHub repository
+2. Navigate to Actions and select a workflow run
+3. Click "Re-run jobs" → check "Enable debug logging"
+4. Wait for the runner to display "DAP debugger waiting for connection..."
+
+### 4. Connect the Extension
+
+1. Navigate to the job page (`github.com/.../actions/runs/.../job/...`)
+2. Click the extension icon in Chrome toolbar
+3. Click "Connect"
+4. The debugger pane will appear above the first workflow step
+
+## Usage
+
+### Variable Browser (Left Panel)
+
+Click on scope names to expand and view variables:
+- **Globals**: `github`, `env`, `runner` contexts
+- **Job Outputs**: Outputs from previous jobs
+- **Step Outputs**: Outputs from previous steps
+
+### Console (Right Panel)
+
+Enter expressions or commands:
+
+```bash
+# Evaluate expressions
+${{ github.ref }}
+${{ github.event_name }}
+${{ env.MY_VAR }}
+
+# Run shell commands (prefix with !)
+!ls -la
+!cat package.json
+!env | grep GITHUB
+
+# Modify variables
+!export MY_VAR=new_value
+```
+
+### Control Buttons
+
+| Button | Action | Description |
+|--------|--------|-------------|
+| ⏮ | Reverse Continue | Go back to first checkpoint |
+| ◀ | Step Back | Go to previous checkpoint |
+| ▶ | Continue | Run until next breakpoint/end |
+| ⏭ | Step (Next) | Step to next workflow step |
+
+## Architecture
+
+```
+Browser Extension ──WebSocket──► Proxy ──TCP──► Runner DAP Server
+    (port 4712)                              (port 4711)
+```
+
+The WebSocket proxy handles DAP message framing (Content-Length headers) and provides a browser-compatible connection.
+
+## Configuration
+
+### Proxy Settings
+
+| Environment Variable | Default | Description |
+|---------------------|---------|-------------|
+| `WS_PORT` | 4712 | WebSocket server port |
+| `DAP_HOST` | 127.0.0.1 | DAP server host |
+| `DAP_PORT` | 4711 | DAP server port |
+
+Or use CLI arguments:
+```bash
+node proxy.js --ws-port 4712 --dap-host 127.0.0.1 --dap-port 4711
+```
+
+### Extension Settings
+
+Click the extension popup to configure:
+- **Proxy Host**: Default `localhost`
+- **Proxy Port**: Default `4712`
+

+```
+
+## Troubleshooting
+
+### "Failed to connect to DAP server"
+
+1. Ensure the proxy is running: `node proxy.js`
+2. Ensure the runner is waiting for a debugger connection
+3. Check that debug logging is enabled for the job
+
+### Debugger pane doesn't appear
+
+1. Verify you're on a job page (`/actions/runs/*/job/*`)
+2. Open DevTools and check for console errors
+3. Reload the page after loading the extension
+
+### Variables don't load
+
+1. Wait for the "stopped" event (status shows PAUSED)
+2. Click on a scope to expand it
+3. Check the console for error messages
+
+## Development
+
+### Modifying the Extension
+
+After making changes:
+1. Go to `chrome://extensions/`
+2. Click the refresh icon on the extension card
+3. Reload the GitHub job page
+
+### Debugging
+
+- **Background script**: Inspect via `chrome://extensions/` → "Inspect views: service worker"
+- **Content script**: Use DevTools on the GitHub page
+- **Proxy**: Watch terminal output for message logs
+
+## Security Note
+
+The proxy and extension are designed for local development. The proxy only accepts connections from localhost. Do not expose the proxy to the network without additional security measures.

 ```
 
+#### 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:

+            "fromPath": "ClassLibrary/ClassLibrary.csproj",

+# ADR 2494: Runner Image Tags
+
+**Date**: 2023-03-17
+
+**Status**: Accepted<!-- |Accepted|Rejected|Superceded|Deprecated -->
+
+## Context
+
+Following the [adoption of actions-runner-controller by GitHub](https://github.com/actions/actions-runner-controller/discussions/2072) and the introduction of the new runner scale set autoscaling mode, we needed to provide a basic runner image that could be used off the shelf without much friction.
+
+The [current runner image](https://github.com/actions/runner/pkgs/container/actions-runner) is published to GHCR. Each release of this image is tagged with the runner version and the most recent release is also tagged with `latest`.
+
+While the use of `latest` is common practice, we recommend that users pin a specific version of the runner image for a predictable runtime and improved security posture. However, we still notice that a large number of end users are relying on the `latest` tag & raising issues when they encounter problems.
+
+Add to that, the community actions-runner-controller maintainers have issued a [deprecation notice](https://github.com/actions/actions-runner-controller/issues/2056) of the `latest` tag for the existing runner images (https://github.com/orgs/actions-runner-controller/packages).
+
+## Decision
+
+Proceed with Option 2, keeping the `latest` tag and adding the `NOTES.txt` file to our helm charts with the notice.
+
+### Option 1: Remove the `latest` tag
+
+By removing the `latest` tag, we have to proceed with either of these options:
+
+1. Remove the runner image reference in the `values.yaml` provided with the `gha-runner-scale-set` helm chart and mark these fields as required so that users have to explicitly specify a runner image and a specific tag. This will obviously introduce more  friction for users who want to start using actions-runner-controller for the first time.
+
+```yaml
+  spec:
+    containers:
+    - name: runner
+      image: ""
+      tag: ""
+      command: ["/home/runner/run.sh"]
+```
+
+1. Pin a specific runner image tag in the `values.yaml` provided with the `gha-runner-scale-set` helm chart. This will reduce friction for users who want to start using actions-runner-controller for the first time but will require us to update the `values.yaml` with every new runner release.
+
+```yaml
+  spec:
+    containers:
+    - name: runner
+      image: "ghcr.io/actions/actions-runner"
+      tag: "v2.300.0"
+      command: ["/home/runner/run.sh"]
+```
+
+### Option 2: Keep the `latest` tag
+
+Keeping the `latest` tag is also a reasonable option especially if we don't expect to make any breaking changes to the runner image. We could enhance this by adding a [NOTES.txt](https://helm.sh/docs/chart_template_guide/notes_files/) to the helm chart which will be displayed to the user after a successful helm install/upgrade. This will help users understand the implications of using the `latest` tag and how to pin a specific version of the runner image.
+
+The runner image release workflow will need to be updated so that the image is pushed to GHCR and tagged only when the runner rollout has reached all scale units.
+
+## Consequences
+
+Proceeding with **option 1** means:
+
+1. We will enhance the runtime predictability and security posture of our end users
+1. We will have to update the `values.yaml` with every new runner release (that can be automated)
+1. We will introduce friction for users who want to start using actions-runner-controller for the first time
+
+Proceeding with **option 2** means:
+
+1. We will have to continue to maintain the `latest` tag
+1. We will assume that end users will be able to handle the implications of using the `latest` tag
+1. Runner image release workflow needs to be updated

+# Runner Dependency Management Process
+
+## Overview
+
+This document outlines the automated dependency management process for the GitHub Actions Runner, designed to ensure we maintain up-to-date and secure dependencies while providing predictable release cycles.
+
+## Release Schedule
+
+- **Monthly Runner Releases**: New runner versions are released monthly
+- **Weekly Dependency Checks**: Automated workflows check for dependency updates every Monday
+- **Security Patches**: Critical security vulnerabilities are addressed immediately outside the regular schedule
+
+## Automated Workflows
+
+**Note**: These workflows are implemented across separate PRs for easier review and independent deployment. Each workflow includes comprehensive error handling and security-focused vulnerability detection.
+
+### 1. Foundation Labels
+
+- **Workflow**: `.github/workflows/setup-labels.yml` (PR #4024)
+- **Purpose**: Creates consistent dependency labels for all automation workflows
+- **Labels**: `dependencies`, `security`, `typescript`, `needs-manual-review`
+- **Prerequisite**: Must be merged before other workflows for proper labeling
+
+### 2. Node.js Version Updates
+
+- **Workflow**: `.github/workflows/node-upgrade.yml`
+- **Schedule**: Mondays at 6:00 AM UTC
+- **Purpose**: Updates Node.js 20 and 24 versions in `src/Misc/externals.sh`
+- **Source**: [nodejs.org](https://nodejs.org) and [actions/alpine_nodejs](https://github.com/actions/alpine_nodejs)
+- **Priority**: First (NPM depends on current Node.js versions)
+
+### 3. NPM Security Audit
+
+- **Primary Workflow**: `.github/workflows/npm-audit.yml` ("NPM Audit Fix")
+  - **Schedule**: Mondays at 7:00 AM UTC
+  - **Purpose**: Automated security vulnerability detection and basic fixes
+  - **Location**: `src/Misc/expressionFunc/hashFiles/`
+  - **Features**: npm audit, security patch application, PR creation
+  - **Dependency**: Runs after Node.js updates for optimal compatibility
+
+- **Fallback Workflow**: `.github/workflows/npm-audit-typescript.yml` ("NPM Audit Fix with TypeScript Auto-Fix")
+  - **Trigger**: Manual dispatch only
+  - **Purpose**: Manual security audit with TypeScript compatibility fixes
+  - **Use Case**: When scheduled workflow fails or needs custom intervention
+  - **Features**: Enhanced TypeScript auto-repair, graduated security response
+  - **How to Use**:
+    1. If the scheduled "NPM Audit Fix" workflow fails, go to Actions tab
+    2. Select "NPM Audit Fix with TypeScript Auto-Fix" workflow
+    3. Click "Run workflow" and optionally specify fix level (auto/manual)
+    4. Review the generated PR for TypeScript compatibility issues
+
+### 4. .NET SDK Updates
+
+- **Workflow**: `.github/workflows/dotnet-upgrade.yml`
+- **Schedule**: Mondays at midnight UTC
+- **Purpose**: Updates .NET SDK and package versions with build validation
+- **Features**: Global.json updates, NuGet package management, compatibility checking
+- **Independence**: Runs independently of Node.js/NPM updates
+
+### 5. Docker/Buildx Updates
+
+- **Workflow**: `.github/workflows/docker-buildx-upgrade.yml` ("Docker/Buildx Version Upgrade")
+- **Schedule**: Mondays at midnight UTC
+- **Purpose**: Updates Docker and Docker Buildx versions with multi-platform validation
+- **Features**: Container security scanning, multi-architecture build testing
+- **Independence**: Runs independently of other dependency updates
+
+### 6. Dependency Monitoring
+
+- **Workflow**: `.github/workflows/dependency-check.yml` ("Dependency Status Check")
+- **Schedule**: Mondays at 11:00 AM UTC
+- **Purpose**: Comprehensive status report of all dependencies with security audit
+- **Features**: Multi-dependency checking, npm audit status, build validation, choice of specific component checks
+- **Summary**: Runs last to capture results from all morning dependency updates
+
+## Release Process Integration
+
+### Pre-Release Checklist
+
+Before each monthly runner release:
+
+1. **Check Dependency PRs**:
+
+   ```bash
+   # List all open dependency PRs
+   gh pr list --label "dependencies" --state open
+   
+   # List only automated weekly dependency updates
+   gh pr list --label "dependencies-weekly-check" --state open
+   
+   # List only custom dependency automation (not dependabot)
+   gh pr list --label "dependencies-not-dependabot" --state open
+   ```
+
+2. **Run Manual Dependency Check**:
+   - Go to Actions tab → "Dependency Status Check" → "Run workflow"
+   - Review the summary for any outdated dependencies
+
+3. **Review and Merge Updates**:
+   - Prioritize security-related updates
+   - Test dependency updates in development environment
+   - Merge approved dependency PRs
+
+### Vulnerability Response
+
+#### Critical Security Vulnerabilities
+
+- **Response Time**: Within 24 hours
+- **Process**:
+  1. Assess impact on runner security
+  2. Create hotfix branch if runner data security is affected
+  3. Expedite patch release if necessary
+  4. Document in security advisory if applicable
+
+#### Non-Critical Vulnerabilities
+
+- **Response Time**: Next monthly release
+- **Process**:
+  1. Evaluate if vulnerability affects runner functionality
+  2. Include fix in regular dependency update cycle
+  3. Document in release notes
+
+## Monitoring and Alerts
+
+### GitHub Actions Workflow Status
+
+- All dependency workflows create PRs with the `dependencies` label
+- Failed workflows should be investigated immediately
+- Weekly dependency status reports are generated automatically
+
+### Manual Checks
+
+You can manually trigger dependency checks:
+
+- **Full Status**: Run "Dependency Status Check" workflow
+- **Specific Component**: Use the dropdown to check individual dependencies
+
+## Dependency Labels
+
+All automated dependency PRs are tagged with labels for easy filtering and management:
+
+### Primary Labels
+
+- **`dependencies`**: All automated dependency-related PRs
+- **`dependencies-weekly-check`**: Automated weekly dependency updates from scheduled workflows
+- **`dependencies-not-dependabot`**: Custom dependency automation (not created by dependabot)
+- **`security`**: Security vulnerability fixes and patches  
+- **`typescript`**: TypeScript compatibility and type definition updates
+- **`needs-manual-review`**: Complex updates requiring human verification
+
+### Technology-Specific Labels
+
+- **`node`**: Node.js version updates
+- **`javascript`**: JavaScript runtime and tooling updates
+- **`npm`**: NPM package and security updates
+- **`dotnet`**: .NET SDK and NuGet package updates
+- **`docker`**: Docker and container tooling updates
+
+### Workflow-Specific Branches
+
+- **Node.js updates**: `chore/update-node` branch
+- **NPM security fixes**: `chore/npm-audit-fix-YYYYMMDD` and `chore/npm-audit-fix-with-ts-repair` branches
+- **NuGet/.NET updates**: `feature/dotnetsdk-upgrade/{version}` branches
+- **Docker updates**: `feature/docker-buildx-upgrade` branch
+
+## Special Considerations
+
+### Node.js Updates
+
+When updating Node.js versions, remember to:
+
+1. Create a corresponding release in [actions/alpine_nodejs](https://github.com/actions/alpine_nodejs)
+2. Follow the alpine_nodejs getting started guide
+3. Test container builds with new Node versions
+
+### .NET SDK Updates
+
+- Only patch versions are auto-updated within the same major.minor version
+- Major/minor version updates require manual review and testing
+
+### Docker Updates
+
+- Updates include both Docker Engine and Docker Buildx
+- Verify compatibility with runner container workflows
+
+## Troubleshooting
+
+### Common Issues
+
+1. **NPM Audit Workflow Fails**:
+   - Check if `package.json` exists in `src/Misc/expressionFunc/hashFiles/`
+   - Verify Node.js setup step succeeded
+
+2. **Version Detection Fails**:
+   - Check if upstream APIs are available
+   - Verify parsing logic for version extraction
+
+3. **PR Creation Fails**:
+   - Ensure `GITHUB_TOKEN` has sufficient permissions
+   - Check if branch already exists
+
+### Contact
+
+For questions about the dependency management process:
+
+- Create an issue with the `dependencies` label
+- Review existing dependency management workflows
+- Consult the runner team for security-related concerns
+
+## Metrics and KPIs
+
+Track these metrics to measure dependency management effectiveness:
+
+- Number of open dependency PRs at release time
+- Time to merge dependency updates
+- Number of security vulnerabilities by severity
+- Release cycle adherence (monthly target)
