Merge branch 'develop' into fix/roadmap-tasks

- ROADMAP_UPDATE_FEATURE handler now clears task_outcome and
  previous_status when status moves away from done, matching the
  renderer store behavior
- Add tests for markFeatureDoneBySpecId (previousStatus preservation,
  taskOutcome setting, feature isolation)
- Add tests for updateFeatureStatus clearing taskOutcome/previousStatus

-# GitHub Issues Documentation Design
-
-**Date:** 2025-02-16
-**Status:** Approved
-**Author:** Claude (Superpowers Brainstorming)
-
-## Overview

-
-## Target Audience
-
-**Mixed audience with progressive depth:**
-- **End users** - New to Auto Claude, want to understand features and get started quickly
-- **Technical users** - Existing users wanting to optimize AI configuration and manage costs
-- **Pro users/developers** - Want to customize prompts, context injection, and extend the system
-
-## Document Structure
-
-### New Directory: `guides/github-issues/`
-
-```
-guides/
-└── github-issues/
-    ├── README.md                                    # Navigation index
-    ├── github-issues-user-guide.md                  # Document 1
-    ├── github-issues-advanced-ai-configuration.md   # Document 2

-
-## Content Approach
-
-### Progressive Disclosure
-- Each document builds on the previous one
-- Clear navigation links between documents
-- Users can enter at their appropriate level
-
-### Writing Style Guidelines
-
-| Document | Tone | Language | Example Style |
-|----------|------|----------|---------------|
-| User Guide | Friendly, encouraging | Plain English | "Think of AI investigation as having a senior developer analyze the issue for you" |
-| Advanced Config | Professional, technical | Terms explained in context | "Fast Mode uses optimized token generation to reduce investigation time by 2.5x" |
-| Customization | Developer-to-developer | Technical, code-heavy | "Modify the `<system_context>` variable in `prompts/github/root_cause.xml`" |
-
-### Code & Configuration Examples
-- **Doc 1:** Simple copy-paste examples, UI navigation
-- **Doc 2:** Configuration snippets, environment variables
-- **Doc 3:** Full XML/Python examples, file paths, code blocks
-
-## Visual Elements
-
-### Screenshots (Hybrid Approach)
-
-**User Guide:**
-1. GitHub Issues main UI (issue list, filters, actions)
-2. Issue detail view (comments, labels, "Investigate" button)
-3. Investigation in progress (4 parallel specialists)
-4. Investigation results (completed report)
-5. Settings screen (GitHub auth, repo connection, Fast Mode toggle)
-
-**Advanced AI Config:**
-1. Settings → AI Investigation panel (configurable options)
-2. Token usage display (cost visibility)
-3. Investigation pipeline flowchart (issue → 4 specialists → report)
-
-**Customization Guide:**
-1. Directory structure diagram (prompt file locations)
-2. Annotated XML prompt file (variables and structure)
-3. Context injection flow diagram
-4. Code snippets throughout
-
-### Diagram Style
-- Clean, simple flowcharts
-- Consistent color scheme: Blue (user actions), Green (AI agents), Orange (data flow)
-- Minimal text, focus on flow and relationships
-
-## Navigation & Cross-References
-
-### Linking Strategy
-
-**User Guide → Deeper:**
-- "For detailed configuration, see [Advanced AI Configuration]"
-- "Learn how the 4 specialists work in [Advanced AI Configuration]"
-- "Want to customize agent behavior? See [Customization Guide]"
-
-**Advanced AI Config → Both Directions:**
-- "New to GitHub Issues? Start with the [User Guide]"
-- "Want to modify agent prompts? See [Customization Guide]"
-
-**Customization Guide → Reference:**
-- "Assumes familiarity with concepts from [User Guide] and [Advanced AI Config]"
-
-### Navigation Aids
-- Table of Contents at the top of each document
-- "In this section" callouts at the start of major sections
-- "Next steps" boxes at the end of each workflow section
-
-### External References
-- `guides/opus-4.6-features.md` - Opus 4.6 details (don't duplicate)
-- `ARCHITECTURE.md` - System architecture
-- GitHub CLI docs - Authentication setup
-
-## Key Emphasis
-
-**Integration Workflow** is the primary focus across all documents:
-
-> **Import Issues** → **AI Investigation** → **Create Task** → **Implement** → **Merge**
-
-This pipeline demonstrates the core value of Auto Claude - connecting GitHub issues to autonomous development.
-
-## File Organization
-
-### Naming Convention
-- Lowercase with hyphens (matches existing documentation style)
-- Descriptive names indicating audience and content
-- Keep under 80 characters for GitHub rendering
-
-### README.md (Index Page)
-
-```markdown
-# GitHub Issues Documentation
-
-Choose the guide that matches your needs:
-
-📖 **[User Guide](github-issues-user-guide.md)** - Get started with GitHub Issues integration
-  For: All users | Focus: Using the features
-
-⚙️ **[Advanced AI Configuration](github-issues-advanced-ai-configuration.md)** - Optimize AI investigations
-  For: Technical users | Focus: Performance, costs, Opus 4.6
-
-🔧 **[Customization Guide](github-issues-customization-guide.md)** - Extend and customize the system
-  For: Developers | Focus: Prompts, context, customization
-```
-
-## Markdown Format Guidelines
-
-- Standard GitHub-flavored markdown
-- H1 for title, H2 for main sections, H3 for subsections
-- Code blocks with language specification (`xml`, `python`, `bash`)
-- Callout boxes using `> **Note:**` format
-- Internal links use relative paths
-- Front matter with title and description metadata
-
-## Implementation Notes
-
-### Content Sources
-- `apps/frontend/src/renderer/components/github-issues/` - UI components
-- `apps/frontend/src/main/ipc-handlers/github/` - IPC handlers
-- `apps/backend/runners/github/` - Backend services
-- `guides/opus-4.6-features.md` - Reference for Opus 4.6 details
-- Existing code comments and docstrings
-
-### Screenshots to Capture
-- Need to run the application in development mode (`npm run dev`)
-- Capture each UI state listed in Visual Elements section
-- Save to `guides/github-issues/images/` with descriptive names
-
-### Diagram Creation
-- Use Mermaid syntax for flowcharts (if supported by docs build)
-- Alternatively, describe for manual creation with diagram tools
-
-## Success Criteria
-
-1. ✅ All three documents created in `guides/github-issues/`
-2. ✅ README.md index page created
-3. ✅ Progressive structure allows users to enter at appropriate level

-2. Set up directory structure
-3. Draft content for each document
-4. Capture screenshots
-5. Create diagrams
-6. Review and refine
-7. Commit to repository

-To fully clear all PR review data so reviews run fresh, delete/reset these three things in `.auto-claude/github/`:
-
-1. `rm .auto-claude/github/pr/logs_*.json` — review log files
-2. `rm .auto-claude/github/pr/review_*.json` — review result files

-Dependency Strategy Mapping
-============================
-
-Maps dependency types to sharing strategies for worktree creation.
-
-Each dependency ecosystem has different constraints:
-
-- **node_modules**: Safe to symlink. Node's resolution algorithm follows symlinks
-  correctly, and the directory is self-contained.
-
-- **venv / .venv**: Must be recreated. Python's ``pyvenv.cfg`` discovery walks the
-  real directory hierarchy without resolving symlinks (CPython bug #106045), so a
-  symlinked venv resolves paths relative to the *target*, not the worktree.
-
-- **vendor (PHP)**: Safe to symlink. Composer's autoloader uses ``__DIR__``-relative
-  paths that resolve correctly through symlinks.
-
-- **cargo target / go modules**: Skip entirely. Rust's ``target/`` dir contains
-  per-machine build artifacts that must be rebuilt. Go uses a global module cache
-  (``$GOPATH/pkg/mod``), so there is nothing in-tree to share.

-<title>Design Fix Approaches</title>
-For each approach, specify:
-- What to change: Exact files and the nature of the modification
-- Complexity: simple (< 1 hour), moderate (1-4 hours), complex (> 4 hours)
-- Pros: Why this approach is good

-- Do NOT conclude with "medium" or "low" confidence if you still have unexplored code paths you could Read or Grep
-- If the issue mentions a UI behavior, trace it from the React component through the store, IPC handler, and into the backend
-- If you find the likely cause early, keep investigating to VERIFY it — read callers, check edge cases, look for related patterns
-- Use your full tool budget. Read more files, run more greps. Thoroughness is more valuable than speed for root cause analysis

-Provide your analysis as structured output with:
-- identified_root_cause: Clear description of what causes the issue
-- code_paths: Ordered list of code locations from entry point to root cause
-- confidence: Your confidence level (high/medium/low)
-- evidence: Code snippets and traces supporting your analysis
-- related_issues: Known issue patterns this matches (e.g., "race condition", "null reference")
-- likely_already_fixed: True if evidence suggests the issue is already resolved

-### The Problem: `~/.claude.json` Race Condition
-
-When multiple agents spawn concurrently, they all attempt to read and write to `~/.claude.json`:
-
-```
-Agent 1: Read ~/.claude.json → Modify → Write
-Agent 2: Read ~/.claude.json → Modify → Write (concurrently!)
-Agent 3: Read ~/.claude.json → Modify → Write (concurrently!)
-```
-
-This caused:
-- **JSON corruption**: Invalid JSON structure from interleaved writes
-- **Backup file accumulation**: `.claude.json.backup`, `.claude.json.backup.1`, etc.
-- **Lost configuration**: Last write wins, earlier changes lost
-- **Mysterious failures**: Agents failing with "invalid JSON" errors
-
-### The Solution: Sequential Spawning via SpawnQueue
-
-All agent types now execute **sequentially** through a FIFO queue:
-
-```
-Request 1 (ideation) → Spawn → Wait for exit → Next
-Request 2 (roadmap)  → Spawn → Wait for exit → Next
-Request 3 (ideation) → Spawn → Wait for exit → Next
-```
-
-**Benefits:**
-- No concurrent writes to `~/.claude.json`
-- No JSON corruption or backup files
-- Predictable execution order
-- Simple error recovery (continue on failure)

-
-### Data Flow
-
-1. **User Request**: User triggers ideation or roadmap generation from UI
-2. **Enqueue**: `AgentQueueManager` creates `SpawnRequest` and enqueues it
-3. **Queue Processing**: `SpawnQueue` processes requests FIFO
-4. **Spawn Execution**: Router calls `executeIdeationSpawn()` or `executeRoadmapSpawn()`
-5. **Process Tracking**: Spawned process added to `AgentState` for tracking
-6. **Event Handlers**: stdout/stderr/exit handlers attached to process
-7. **Wait for Exit**: Queue waits for process to exit before processing next
-8. **Completion**: Success/error events emitted to renderer process
-
-### Queue Behavior
-
-**FIFO Processing:**
-- First in, first out
-- No priority system (simple is better)
-- All agent types share same queue
-
-**Error Resilience:**
-- If spawn fails, invoke `onError` callback
-- Continue to next item in queue
-- Don't block queue on single failure
-
-**Sequential Execution:**
-- Only one agent spawns at a time
-- Wait for `process.exit()` before next spawn
-- Prevents `~/.claude.json` race condition
-
-## Agent Types
-
-### Ideation Agents
-
-**Purpose**: Discover improvements, performance issues, security vulnerabilities
-
-**Runner**: `apps/backend/runners/ideation_runner.py`
-
-**Types**:
-- `discovery`: Code improvements and refactorings
-- `performance`: Performance optimizations
-- `security`: Security vulnerabilities
-- `testing`: Test coverage gaps
-- `documentation`: Documentation improvements
-- `accessibility`: Accessibility issues
-
-**Process Type**: `'ideation'`
-
-**Events**:
-- `ideation-progress`: Progress updates with phase/message
-- `ideation-log`: Log output lines
-- `ideation-type-complete`: Single type completed with ideas
-- `ideation-type-failed`: Single type failed
-- `ideation-complete`: All types completed
-- `ideation-error`: Fatal error
-- `ideation-stopped`: User stopped generation
-
-### Roadmap Agents
-
-**Purpose**: Generate strategic roadmap with competitor analysis
-
-**Runner**: `apps/backend/runners/roadmap_runner.py`
-
-**Features**:
-- Strategic feature planning
-- Competitive analysis (optional)
-- Timeline estimation
-- Priority ranking
-
-**Process Type**: `'roadmap'`
-
-**Events**:
-- `roadmap-progress`: Progress updates with phase/message
-- `roadmap-log`: Log output lines
-- `roadmap-complete`: Roadmap generated
-- `roadmap-error`: Fatal error
-- `roadmap-stopped`: User stopped generation
-
-### Build Agents (Not in Queue)
-
-**Note**: Build agents (planner, coder, QA) are managed separately by `agent-process.ts` and do **not** go through this queue. They have their own spawning mechanism tied to spec/task lifecycle.
-
-## Process State Tracking
-
-Each spawned process is tracked in `AgentState`:
-
-```typescript
-interface QueuedProcessInfo {
-  taskId: string;           // Project ID or task ID
-  process: ChildProcess;    // Node.js ChildProcess instance
-  startedAt: Date;          // When process was spawned
-  projectPath: string;      // Project directory path
-  spawnId: number;          // Unique spawn ID
-  queueProcessType: 'ideation' | 'roadmap'; // Process type
-}
-```
-
-**Key Methods:**
-- `addProcess(projectId, info)`: Track spawned process
-- `getProcess(projectId)`: Get process info
-- `deleteProcess(projectId)`: Remove from tracking
-- `generateSpawnId()`: Generate unique spawn ID
-- `wasSpawnKilled(spawnId)`: Check if intentionally stopped
-- `clearKilledSpawn(spawnId)`: Clear killed flag
-
-## Adding New Agent Types
-
-To add a new agent type to the sequential queue:
-
-### 1. Define Process Type
-
-Add to `QueuedProcessInfo` type in `agent-state.ts`:
-
-```typescript
-queueProcessType: 'ideation' | 'roadmap' | 'new-type';
-```
-
-### 2. Create Spawn Executor
-
-Add method in `AgentQueueManager`:
-
-```typescript
-private async executeNewTypeSpawn(
-  spawnId: string,
-  projectPath: string,
-  args: string[],
-  env: Record<string, string>,
-  projectId: string,
-  cwd: string
-): Promise<ChildProcess> {
-  // Spawn the process
-  const childProcess = spawn(/* ... */);
-
-  // Add to state tracking
-  this.state.addProcess(projectId, {
-    taskId: projectId,
-    process: childProcess,
-    startedAt: new Date(),
-    projectPath,
-    spawnId: parseInt(spawnId, 10),
-    queueProcessType: 'new-type'
-  });
-
-  return childProcess;
-}
-```
-
-### 3. Create Spawn Wrapper
-
-Add method in `AgentQueueManager` to enqueue requests:
-
-```typescript
-async startNewTypeGeneration(
-  projectId: string,
-  projectPath: string,
-  config: NewTypeConfig
-): Promise<void> {
-  // Build args
-  const args = ['runner.py', '--project', projectPath];
-
-  // Enqueue spawn request
-  this.spawnQueue.enqueue({
-    id: String(spawnId),
-    type: 'new-type',
-    projectId,
-    projectPath,
-    args,
-    env: finalEnv,
-    cwd,
-    onSpawn: async (childProcess) => {
-      // Attach event handlers
-      childProcess.stdout?.on('data', (data) => { /* ... */ });
-      childProcess.on('exit', (code) => { /* ... */ });
-    },
-    onError: (error) => {
-      this.emitter.emit('new-type-error', projectId, error.message);
-    }
-  });
-}
-```
-
-### 4. Update SpawnQueue Router
-
-Update constructor in `AgentQueueManager`:
-
-```typescript
-this.spawnQueue = new SpawnQueue(async (id, projectPath, args, env, projectId, cwd, type = 'ideation') => {
-  if (type === 'roadmap') {
-    return this.executeRoadmapSpawn(id, projectPath, args, env, projectId, cwd);
-  } else if (type === 'new-type') {
-    return this.executeNewTypeSpawn(id, projectPath, args, env, projectId, cwd);
-  } else {
-    return this.executeIdeationSpawn(id, projectPath, args, env, projectId, cwd);
-  }
-});
-```
-
-### 5. Add Event Emitter Methods
-
-Add stop/status methods:
-
-```typescript
-stopNewType(projectId: string): boolean {
-  const processInfo = this.state.getProcess(projectId);
-  const isNewType = processInfo?.queueProcessType === 'new-type';
-
-  if (isNewType) {
-    this.processManager.killProcess(projectId);
-    this.emitter.emit('new-type-stopped', projectId);
-    return true;
-  }
-  return false;
-}
-
-isNewTypeRunning(projectId: string): boolean {
-  const processInfo = this.state.getProcess(projectId);
-  return processInfo?.queueProcessType === 'new-type';
-}
-```
-
-## Rate Limit Detection
-
-The queue system automatically detects API rate limits:
-
-1. **Collect Output**: stdout/stderr collected during process execution
-2. **Detect Patterns**: Checks for rate limit error messages
-3. **Emit Event**: `sdk-rate-limit` event with detection info
-4. **Auto-Switch**: Profile scorer automatically switches to next available profile
-
-**Detection**:
-```typescript
-const rateLimitDetection = detectRateLimit(allOutput);
-if (rateLimitDetection.isRateLimited) {
-  const rateLimitInfo = createSDKRateLimitInfo('ideation', rateLimitDetection, { projectId });
-  this.emitter.emit('sdk-rate-limit', rateLimitInfo);
-}
-```
-
-## Python Environment Management
-
-Agents require a Python environment with dependencies:
-
-1. **Pre-flight Check**: `ensurePythonEnvReady()` checks if venv is ready
-2. **Venv Creation**: If needed, creates venv and installs dependencies
-3. **Python Path**: Uses configured Python path (or bundled Python)
-4. **PYTHONPATH**: Bundled site-packages + autoBuildSource for imports
-
-**Environment Variables**:
-```typescript
-const finalEnv = {
-  ...process.env,
-  ...pythonEnv,           // Bundled packages
-  ...combinedEnv,         // auto-claude/.env
-  ...profileEnv,          // OAuth token
-  ...apiProfileEnv,       // API profile config
-  PYTHONPATH: combinedPythonPath,
-  PYTHONUNBUFFERED: '1',
-  PYTHONUTF8: '1'
-};
-```
-
-## Progress Persistence
-
-Roadmap generation persists progress to disk for recovery:
-
-- **File**: `.auto-claude/roadmap/generation_progress.json`
-- **Debounced**: 300ms debounce (3-4 writes/sec max)
-- **Leading + Trailing**: Immediate first write, final state on completion
-- **Recovery**: Process can recover after app restart
-
-**Progress Data**:
-```json
-{
-  "phase": "analyzing",
-  "progress": 45,
-  "message": "Analyzing codebase...",
-  "started_at": "2025-02-15T10:30:00Z",
-  "last_update_at": "2025-02-15T10:35:00Z",
-  "is_running": true
-}
-```
-
-## Debug Logging
-
-All operations are logged for debugging:
-
-```typescript
-debugLog('[Agent Queue] Starting ideation generation:', { projectId, projectPath, config });
-debugLog('[Agent Queue] Generated spawn ID:', spawnId);
-debugLog('[Agent Queue] Ideation process spawned:', { spawnId, projectId, pid });
-```
-
-**Enable Debug Logs**:
-- Dev mode: Logs always visible
-- Production: Set `DEBUG=auto-claude:*` environment variable
-
-## Error Handling
-
-### Spawn Errors
-
-If process spawn fails:
-1. `onError` callback invoked
-2. Error event emitted to renderer
-3. Queue continues to next item
-
-**Example**:
-```typescript
-onError: (error) => {
-  debugError('[Agent Queue] Failed to spawn ideation process:', error);
-  this.emitter.emit('ideation-error', projectId, error.message);
-}
-```
-
-### Process Errors
-
-If process errors after spawn:
-1. `process.on('error')` handler invoked
-2. Process removed from state tracking
-3. Error event emitted to renderer
-
-### Exit Codes
-
-- **Code 0**: Success
-- **Code ≠ 0**: Failure (check for rate limits)
-
-## Testing
-
-### Manual Testing
-
-```bash
-# Start app in dev mode
-npm run dev
-
-# Trigger multiple agents simultaneously:
-# 1. Open 3 projects
-# 2. Click "Generate Ideas" on all 3 quickly
-# 3. Click "Generate Roadmap" on 2 projects
-# 4. Monitor console - should see sequential execution
-# 5. Check ~/.claude.json - should be valid JSON
-# 6. No .backup files should be created
-```
-
-### Automated Testing
-
-```bash
-# Run frontend tests
-cd apps/frontend
-npm test
-
-# Typecheck
-npm run typecheck
-
-# Lint
-npm run lint
-```

-## Troubleshooting
-
-### Agents Not Starting
-
-**Symptom**: Click "Generate Ideas" but nothing happens
-
-**Checks**:
-1. Check Python path is configured in settings
-2. Check autoBuildSource path is set
-3. Check runner files exist (`ideation_runner.py`, `roadmap_runner.py`)
-4. Check debug logs for errors
-
-### JSON Corruption
-
-**Symptom**: `~/.claude.json` is invalid JSON
-
-**Checks**:
-1. Check if queue is being used (should be sequential)
-2. Check for concurrent spawns (shouldn't happen)
-3. Check backup files (.backup, .backup.1)
-4. Restore from backup: `cp ~/.claude.json.backup ~/.claude.json`
-
-### Rate Limiting
-
-**Symptom**: Agents fail with rate limit errors
-
-**Solution**:
-1. System automatically switches to next available profile
-2. Add more Claude profiles in settings
-3. Wait for rate limit to reset (1 minute)
-
-### Process Won't Stop
-
-**Symptom**: Click "Stop" but process keeps running
-
-**Checks**:
-1. Check process ID in debug logs
-2. Check if `wasIntentionallyStopped` flag is set
-3. Check if process is tracked in AgentState
-4. Manual kill: `kill <PID>` (macOS/Linux) or `taskkill /PID <PID>` (Windows)

- * - Each agent type gets unique process tracking via queueProcessType
- *
- * **Architecture:**
- * - User calls startIdeationGeneration() or startRoadmapGeneration()
- * - Request enqueued in spawnQueue with type ('ideation' | 'roadmap')
- * - Queue routes to executeIdeationSpawn() or executeRoadmapSpawn()
- * - Process spawned, tracked in AgentState, event handlers attached
- * - Queue waits for process.exit() before processing next item
- *
- * **Process Types:**
- * - 'ideation': Idea generation (discoveries, performance, security)
- * - 'roadmap': Strategic roadmap generation with competitor analysis
- * - 'build': Build agents (managed separately, not in this queue)
