fix(codeql): fix high-severity CodeQL issues

- Replace MD5 with SHA-256 for finding ID generation (4 locations)
- Use crypto.randomBytes() instead of Math.random() for temp files (2 files)
- Fix TOCTOU race conditions by using try/catch instead of existsSync (5 files)
- Add __dir__() to lazy import module for static analysis

Fixes the following CodeQL alerts:
- Use of broken/weak cryptographic hashing algorithm
- Insecure temporary file creation
- Potential file system race conditions (TOCTOU)
- Explicit export not defined in __all__

All 3841 frontend tests pass.

-# GIT WORKTREE CONTEXT HANDLING
+# GIT WORKTREE ENVIRONMENT CLEANUP
 # =============================================================================
-# When running in a worktree, we need to preserve git context to prevent HEAD
-# corruption. However, we must also CLEAR these variables when NOT in a worktree
-# to prevent cross-worktree contamination (files leaking between worktrees).
+# Git automatically sets GIT_DIR (and CWD to the working tree root) before
+# running hooks -- even in worktrees. We do NOT need to manually parse .git
+# files or export GIT_DIR/GIT_WORK_TREE.
 #
-# The bug: If GIT_DIR/GIT_WORK_TREE are set from a previous worktree session
-# and this hook runs in the main repo (where .git is a directory, not a file),
-# git commands will target the wrong repository, causing files to appear as
-# untracked in the wrong location.
-#
-# Fix: Explicitly unset these variables when NOT in a worktree context.
+# However, external tools (IDEs, agents, parent shells) may leave stale
+# GIT_DIR/GIT_WORK_TREE values in the environment. If these point to a
+# different repo or worktree, git commands in this hook would target the
+# wrong repository. Unsetting them lets git re-resolve the correct values
+# from the working directory.

+# GitHub Issues Documentation Design
+
+**Date:** 2025-02-16
+**Status:** Approved
+**Author:** Claude (Superpowers Brainstorming)
+
+## Overview
+
+Create comprehensive, user-friendly documentation for Auto Claude's GitHub Issues integration. The documentation will serve a mixed audience (new and existing users) with progressive depth across three documents.
+
+## 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

+2. **Prompt System Architecture** - How agent prompts are structured
+3. **Context Injection System** - How context is built and passed to agents
+4. **Customizing Agent Prompts** - Modifying XML prompt files
+   - Finding the prompt files
+   - Prompt structure and variables
+   - Creating custom investigation specialists
+5. **Context Configuration** - Customizing what data is included
+   - File selection patterns
+   - Context window management
+   - Repository context settings
+6. **Adding Custom Specialists** - Creating new investigation agents
+7. **Extending the Integration** - Hooks, custom providers
+8. **Examples & Recipes** - Common customizations
+
+**Tone:** Developer-to-developer, technical, code-heavy, minimal hand-holding.
+
+## 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

+
+🔧 **[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/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

 **PR target** — Always target the `develop` branch for PRs to AndyMik90/Auto-Claude, NOT `main`.
 
+## Work Approach
+
+**Investigate before speculating** — Always read the actual code before proposing root causes. Spawn agents to grep and read relevant source files before forming any hypothesis. Never guess at causes without evidence from the codebase.
+
+**Spawn agents for complex tasks** — When tackling complex tasks, spawn sub-agents/agent teams immediately rather than trying to handle everything in a single context window. Never attempt to analyze large codebases or multiple features monolithically.
+
+**Minimal fixes only** — Prefer the simplest approach (e.g., prompt-only changes, single guard clause) before suggesting multi-component solutions. If the user asks for X, implement X — don't bundle additional fixes they didn't request.
+
+## Known Gotchas

+**Electron path resolution** — For bug fixes in the Electron app, always check path resolution differences between dev and production builds (`app.isPackaged`, `process.resourcesPath`). Paths that work in dev often break when Electron is bundled for production — verify both contexts.

-# Token Encryption Investigation
-
-## Issue Summary
-
-Auto-Claude users are experiencing API 401 errors ("Invalid bearer token") because the Python backend is passing encrypted tokens (with `enc:` prefix) directly to the Claude Agent SDK without decryption. Standalone Claude Code terminals work correctly because they decrypt these tokens before use.
-
-**Key insight from user thehaffk:** "python cant unencrypt claude token and it launches session with CLAUDE_CODE_OAUTH_TOKEN=enc:djEwtxMGISt3tQ..."
-
-## Token Storage Format
-
-### Encrypted Token Format
-
-Claude Code CLI stores OAuth tokens in an encrypted format with the prefix `enc:`:
-
-```text
-enc:djEwtxMGISt3tQ...
-```
-
-This format is used when tokens are stored in:
-- **macOS**: Keychain (service: "Claude Code-credentials")
-- **Linux**: Secret Service API (DBus, via secretstorage library)
-- **Windows**: Credential Manager / .credentials.json files
-
-### Decrypted Token Format
-
-Valid Claude OAuth tokens have the format:
-```text
-sk-ant-oat01-XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
-```
-
-## Current Token Flow (BROKEN)
-
-1. **Token Storage**: Claude Code CLI stores encrypted token with `enc:` prefix in system keychain
-2. **Token Retrieval**: `apps/backend/core/auth.py::get_auth_token()` retrieves token from:
-   - Environment variable `CLAUDE_CODE_OAUTH_TOKEN`
-   - OR system keychain via `get_token_from_keychain()`
-3. **❌ NO DECRYPTION**: Token is returned as-is with `enc:` prefix intact
-4. **SDK Initialization**: Encrypted token passed to Claude Agent SDK
-5. **API Call Fails**: SDK sends encrypted token to API → 401 error
-
-### Proof of Broken Flow
-
-Test in `apps/backend`:
-```python
-import os
-os.environ['CLAUDE_CODE_OAUTH_TOKEN'] = 'enc:test123'
-
-from core.auth import get_auth_token
-token = get_auth_token()
-print(f"Token: {token}")  # Output: "enc:test123"
-print(f"Encrypted: {token.startswith('enc:')}")  # Output: True
-```
-
-## How Standalone Claude Code CLI Handles Tokens
-
-### Current Understanding
-
-1. **Token Detection**: CLI checks if token starts with `enc:` prefix
-2. **Decryption**: If encrypted, CLI decrypts using platform-specific keyring access
-3. **Authentication**: Decrypted `sk-ant-oat01-` token is used for API calls
-
-### Missing Documentation
-
-Web search for "Claude Code CLI encrypted token enc: prefix decryption" found:
-- Token storage formats (JSON with accessToken, refreshToken, expiresAt)
-- Security issues (tokens exposed in debug logs before v2.1.0)
-- Keychain access patterns for macOS/Linux/Windows
-
-**❌ NOT FOUND**: Specific documentation on how Claude Code CLI decrypts `enc:` tokens
-
-Sources:

-- [Claude Code sessions should be encrypted | yoav.blog](https://yoav.blog/2026/01/09/claude-code-sessions-should-be-encrypted/)
-
-## Decryption Approach Options
-
-### Option 1: Claude Agent SDK Built-in Decryption
-
-**Status**: NEEDS VERIFICATION
-
-The Claude Agent SDK (`claude-agent-sdk>=0.1.19`) may handle decryption internally if:
-- Token is passed to SDK still encrypted
-- SDK detects `enc:` prefix
-- SDK has access to system keyring for decryption
-
-**Action Required**: Check if SDK has decryption capabilities by examining:
-- SDK source code or documentation
-- Whether SDK expects encrypted vs decrypted tokens
-- If SDK requires specific environment variables for decryption
-
-### Option 2: Python Backend Decryption (Recommended)
-
-**Approach**: Implement decryption in `apps/backend/core/auth.py` before passing to SDK
-
-**Implementation Pattern**:
-```python
-def get_auth_token() -> str | None:
-    """Get authentication token (decrypted if necessary)."""
-    token = _retrieve_token_from_sources()  # From env or keychain
-
-    if token and token.startswith("enc:"):
-        # Decrypt the token
-        token = decrypt_token(token)
-
-    return token
-
-def decrypt_token(encrypted_token: str) -> str:
-    """
-    Decrypt Claude Code encrypted token.
-
-    Args:
-        encrypted_token: Token with 'enc:' prefix
-
-    Returns:
-        Decrypted token in format 'sk-ant-oat01-...'
-    """
-    # Remove 'enc:' prefix
-    encrypted_data = encrypted_token[4:]
-
-    # TODO: Implement decryption logic
-    # Questions to answer:
-    # 1. What encryption algorithm does Claude Code use?
-    # 2. Where is the decryption key stored?
-    # 3. Is the decryption key platform-specific (per-user)?
-    # 4. Can we reuse Claude Code's decryption mechanism?
-
-    raise NotImplementedError("Token decryption not yet implemented")
-```
-
-### Option 3: Call Claude Code CLI for Decryption
-
-**Approach**: Use the Claude Code CLI binary to decrypt tokens
-
-```python
-def decrypt_token(encrypted_token: str) -> str:
-    """Decrypt token by invoking Claude Code CLI."""
-    # Find claude binary
-    claude_path = shutil.which("claude") or "~/.local/bin/claude"
-
-    # Use CLI command to get decrypted token
-    # (if such a command exists - needs research)
-    result = subprocess.run(
-        [claude_path, "auth", "decrypt", encrypted_token],
-        capture_output=True,
-        text=True
-    )
-
-    return result.stdout.strip()
-```
-
-**Issues**:
-- Requires Claude Code CLI to be installed
-- No documented CLI command for token decryption
-- Adds external dependency
-
-## Required Investigation Steps
-
-### 1. Verify SDK Decryption Capabilities
-
-**Task**: Check if `claude-agent-sdk` handles `enc:` tokens automatically
-
-**Method**:
-```bash
-# In environment with SDK installed
-python3 << 'EOF'
-import os
-os.environ['CLAUDE_CODE_OAUTH_TOKEN'] = 'enc:...'  # Real encrypted token
-
-from claude_agent_sdk import Client
-# Try creating client - does it decrypt internally?
-client = Client()
-# Check if authentication works
-EOF
-```
-
-### 2. Reverse Engineer Claude Code CLI Decryption
-
-**Task**: Understand how Claude CLI decrypts tokens
-
-**Method**:
-- Examine Claude CLI binary (if possible)
-- Trace system calls when CLI runs (strace on Linux, dtruss on macOS)
-- Check if CLI accesses specific keychain entries for decryption keys
-- Look for encryption/decryption libraries used by CLI
-
-### 3. Find Decryption Key Storage
-
-**Task**: Locate where decryption keys are stored
-
-**Hypothesis**: Decryption key stored in:
-- macOS: Keychain (separate entry from encrypted token)
-- Linux: Secret Service API
-- Windows: Credential Manager
-
-**Verification**:
-```bash
-# macOS: List all keychain entries
-security find-generic-password -a "$(whoami)" | grep -i claude
-
-# Linux: Use secretstorage to list all items
-python3 -c "import secretstorage; ..."
-```
-
-## Recommended Decryption Approach for Python Backend
-
-Based on investigation so far, the recommended approach is:
-
-1. **Detect encrypted tokens**: Check for `enc:` prefix in `get_auth_token()`
-2. **Decrypt before use**: Implement `decrypt_token()` function
-3. **Platform-specific decryption**: Use appropriate keyring library:
-   - macOS: Use `subprocess` with `/usr/bin/security` to access decryption key
-   - Linux: Use `secretstorage` library to access Secret Service API
-   - Windows: Access Credential Manager or credentials.json
-4. **Backward compatibility**: Support both encrypted and plaintext tokens
-5. **Error handling**: Provide clear error messages if decryption fails
-
-## Complete Token Flow Trace (Frontend → Backend)
-
-### 1. Token Retrieval (Frontend)
-
-**File**: `apps/frontend/src/main/services/profile-service.ts`
-
-The frontend retrieves the OAuth token from the system keychain but **does not decrypt it**. When no API profile is active (OAuth mode), the frontend returns an empty environment object, which means it relies on:
-- The token already being in the environment as `CLAUDE_CODE_OAUTH_TOKEN`
-- OR the Python backend retrieving it from the keychain
-
-**Key Code**:
-```typescript
-// Line 223: Returns empty object in OAuth mode, allowing
-// CLAUDE_CODE_OAUTH_TOKEN to be used from system keychain
-```
-
-### 2. Environment Variable Passing (Frontend → PTY)
-
-**File**: `apps/frontend/src/main/terminal/pty-manager.ts`
-
-The PTY manager spawns the terminal shell with environment variables, including `CLAUDE_CODE_OAUTH_TOKEN`:
-
-**Key Code** (Lines 149-152):
-```typescript
-// Remove ANTHROPIC_API_KEY to ensure Claude Code uses OAuth tokens
-// (CLAUDE_CODE_OAUTH_TOKEN from profileEnv) instead of API keys
-const { DEBUG: _DEBUG, ANTHROPIC_API_KEY: _ANTHROPIC_API_KEY, ...cleanEnv } = process.env;
-```
-
-**Important**: The frontend passes through whatever token value exists in the environment - it does NOT check for `enc:` prefix or decrypt it.
-
-### 3. Token Retrieval (Backend)
-
-**File**: `apps/backend/core/auth.py`
-
-#### 3.1. get_auth_token()
-
-This function retrieves the token from multiple sources:
-
-```python
-def get_auth_token() -> str | None:
-    # First check environment variables
-    for var in AUTH_TOKEN_ENV_VARS:  # CLAUDE_CODE_OAUTH_TOKEN, ANTHROPIC_AUTH_TOKEN
-        token = os.environ.get(var)
-        if token:
-            return token  # ❌ Returns immediately without checking for enc: prefix
-
-    # Fallback to system credential store
-    return get_token_from_keychain()  # ❌ Also returns without decryption
-```
-
-**Issue**: Returns token as-is with `enc:` prefix intact.
-
-#### 3.2. require_auth_token()
-
-This function calls `get_auth_token()` and raises an error if no token is found:
-
-```python
-def require_auth_token() -> str:
-    token = get_auth_token()  # ❌ Gets encrypted token
-    if not token:
-        raise ValueError("No OAuth token found...")
-    return token  # ❌ Returns encrypted token
-```
-
-**Issue**: No decryption step between retrieval and return.
-
-#### 3.3. ensure_claude_code_oauth_token()
-
-This function ensures the environment variable is set:
-
-```python
-def ensure_claude_code_oauth_token() -> None:
-    if os.environ.get("CLAUDE_CODE_OAUTH_TOKEN"):
-        return
-
-    token = get_auth_token()  # ❌ Gets encrypted token
-    if token:
-        os.environ["CLAUDE_CODE_OAUTH_TOKEN"] = token  # ❌ Sets encrypted token
-```
-
-**Issue**: Propagates encrypted token to environment variable.
-
-### 4. Token Usage in SDK Client Creation (Backend)
-
-#### 4.1. Full Client Creation
-
-**File**: `apps/backend/core/client.py` (see `create_client()` function)
-
-```python
-def create_client(...):
-    oauth_token = require_auth_token()  # ❌ Gets encrypted token
-    # Ensure SDK can access it via its expected env var
-    os.environ["CLAUDE_CODE_OAUTH_TOKEN"] = oauth_token  # ❌ Sets encrypted token
-```
-
-**Issue**: Encrypted token is passed to the Claude Agent SDK, which expects a decrypted `sk-ant-oat01-` token.
-
-#### 4.2. Simple Client Creation
-
-**File**: `apps/backend/core/simple_client.py` (see `create_simple_client()` function)
-
-```python
-def create_simple_client(...):
-    # Get authentication
-    oauth_token = require_auth_token()  # ❌ Gets encrypted token
-    import os
-    os.environ["CLAUDE_CODE_OAUTH_TOKEN"] = oauth_token  # ❌ Sets encrypted token
-```
-
-**Issue**: Same problem - encrypted token passed to SDK.
-
-#### 4.3. Other Usages
-
-**Files**:
-- `apps/backend/core/workspace.py` (Line 1966) - AI merge operations
-- `apps/backend/runners/insights_runner.py` - Insights analysis
-- `apps/backend/runners/github/batch_issues.py` - GitHub batch operations
-- `apps/backend/integrations/linear/updater.py` - Linear integration
-- `apps/backend/commit_message.py` - Commit message generation
-- `apps/backend/analysis/insight_extractor.py` - Code insights
-- `apps/backend/merge/ai_resolver/claude_client.py` - Merge resolution
-
-**All follow the same pattern**: Call `ensure_claude_code_oauth_token()` → encrypted token in environment → SDK receives encrypted token → API 401 error.

-Based on the flow analysis, decryption should be added at **the earliest point of token retrieval** to avoid duplicating decryption logic:
-
-**RECOMMENDED INSERTION POINT**: `apps/backend/core/auth.py::get_auth_token()`
-
-```python
-def get_auth_token() -> str | None:
-    # First check environment variables
-    for var in AUTH_TOKEN_ENV_VARS:
-        token = os.environ.get(var)
-        if token:
-            # ✅ INSERT DECRYPTION HERE
-            if token.startswith("enc:"):
-                token = decrypt_token(token)
-            return token
-
-    # Fallback to system credential store
-    token = get_token_from_keychain()
-    # ✅ ALSO DECRYPT KEYCHAIN TOKENS
-    if token and token.startswith("enc:"):
-        token = decrypt_token(token)
-    return token
-```
-
-**Benefits of this approach**:
-1. Single location for decryption logic
-2. All downstream functions automatically get decrypted tokens
-3. Backward compatible (plaintext tokens pass through unchanged)
-4. Consistent behavior across all token sources (env vars and keychain)
-
-**Alternative insertion points** (NOT recommended):
-- `require_auth_token()` - Would need similar logic in `get_auth_token()` for non-required usage
-- `create_client()` - Would need duplication in `create_simple_client()` and all other clients
-- `ensure_claude_code_oauth_token()` - Would miss direct `get_auth_token()` calls
-
-## Next Steps
-
-1. ✅ Document current token flow and identify issue (THIS FILE - COMPLETED)
-2. ✅ Trace token flow from frontend to backend (THIS FILE - COMPLETED)
-3. ✅ Identify where decryption should be inserted (THIS FILE - COMPLETED)
-4. ⏳ Verify if Claude Agent SDK handles decryption internally
-5. ⏳ Reverse engineer or document Claude Code CLI decryption mechanism
-6. ⏳ Implement `decrypt_token()` function in `apps/backend/core/auth.py`
-7. ⏳ Add encryption detection and auto-decryption to `get_auth_token()`
-8. ⏳ Test with real encrypted tokens on macOS and Linux
-9. ⏳ Add comprehensive error handling for decryption failures
-
-## Open Questions
-
-1. **What encryption algorithm does Claude Code use for `enc:` tokens?**
-   - Possible: AES-256, ChaCha20, or similar
-   - Key derivation method?
-
-2. **Where is the decryption key stored?**
-   - Same keychain entry as encrypted token?
-   - Separate keychain entry?
-   - Derived from system/user credentials?
-
-3. **Does Claude Agent SDK expect encrypted or decrypted tokens?**
-   - If it expects decrypted: we must decrypt before passing
-   - If it handles encryption: we may be missing SDK configuration
-
-4. **Is there a Claude Code CLI command to decrypt tokens?**
-   - `claude auth decrypt <token>`?
-   - `claude auth get-token`?
-   - No documented command found in research
-
-5. **Can we reuse Claude Code's decryption mechanism?**
-   - Import decryption functions from CLI?
-   - Call CLI as subprocess?
-   - Implement decryption ourselves?

+- Base Branch targeting — check based on target_branch value
+- Type of Change (bug fix, feature, docs, refactor, test) — infer from diff and spec
+- Area (Frontend, Backend, Fullstack) — infer from changed file paths
+- Feature Toggle "N/A" — if the feature appears complete and not behind a flag
+- Breaking Changes "No" — if changes appear backward compatible
+
+**Leave UNCHECKED (these require human verification you cannot perform):**
+- "I've tested my changes locally" — you have not tested anything
+- "All CI checks pass" — CI has not run yet
+- "Windows/macOS/Linux tested" — requires manual testing on each platform
+- "All existing tests pass" — CI has not run yet
+- "New features include test coverage" — unless test files are clearly visible in the diff
+- "Bug fixes include regression tests" — unless test files are clearly visible in the diff
+
+**For platform/code quality checkboxes:**
+- "Used centralized platform/ module" — leave unchecked unless you can verify from the diff
+- "No hardcoded paths" — leave unchecked unless you can verify from the diff
+- "PR is small and focused (< 400 lines)" — check only if diff stats show < 400 lines changed
+
+**For the "I've synced with develop branch" checkbox:**
+- Leave unchecked — you cannot verify the sync status

-Test Discovery Module
-=====================
-
-Detects test frameworks, test commands, and test directories in a project.
-This module analyzes project configuration files to discover how tests
-should be run.
-
-The test discovery results are used by:
-- QA Agent: To determine what test commands to run
-- Test Creator: To know what framework to use when creating tests
-- Planner: To include correct test commands in verification strategy
-
-Usage:
-    from test_discovery import TestDiscovery
-
-    discovery = TestDiscovery()
-    result = discovery.discover(project_dir)
-
-    print(f"Test frameworks: {result['frameworks']}")

+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.
