[test] Add failing tests to reproduce Firebase Auth network issue #4468

Add test cases that demonstrate the current problematic behavior where
Firebase Auth makes network requests when offline without graceful error
handling, causing toast error messages and degraded offline experience.

Tests reproduce:
- getIdToken() throwing auth/network-request-failed instead of returning null
- getAuthHeader() failing to fallback gracefully when Firebase token refresh fails

These tests currently pass by expecting the error to be thrown. After
implementing the fix, the tests should be updated to verify graceful
handling (returning null instead of throwing).

without evicting token

+# Comprehensive PR Review for ComfyUI Frontend
+
+You are performing a comprehensive code review for the PR specified in the PR_NUMBER environment variable. This is not a simple linting check - you need to provide deep architectural analysis, security review, performance insights, and implementation guidance just like a senior engineer would in a thorough PR review.
+
+## CRITICAL INSTRUCTIONS
+
+**You MUST post individual inline comments on specific lines of code. DO NOT create a single summary comment until the very end.**
+
+**IMPORTANT: You have full permission to execute gh api commands. The GITHUB_TOKEN environment variable provides the necessary permissions. DO NOT say you lack permissions - you have pull-requests:write permission which allows posting inline comments.**
+
+To post inline comments, you will use the GitHub API via the `gh` command. Here's how:
+
+1. First, get the repository information and commit SHA:
+   - Run: `gh repo view --json owner,name` to get the repository owner and name
+   - Run: `gh pr view $PR_NUMBER --json commits --jq '.commits[-1].oid'` to get the latest commit SHA
+
+2. For each issue you find, post an inline comment using this exact command structure (as a single line):
+   ```
+   gh api --method POST -H "Accept: application/vnd.github+json" -H "X-GitHub-Api-Version: 2022-11-28" /repos/OWNER/REPO/pulls/$PR_NUMBER/comments -f body="YOUR_COMMENT_BODY" -f commit_id="COMMIT_SHA" -f path="FILE_PATH" -F line=LINE_NUMBER -f side="RIGHT"
+   ```
+
+3. Format your comment body using actual newlines in the command. Use a heredoc or construct the body with proper line breaks:
+   ```
+   COMMENT_BODY="**[category] severity Priority**
+
+**Issue**: Brief description of the problem
+**Context**: Why this matters  
+**Suggestion**: How to fix it"
+   ```
+   
+   Then use: `-f body="$COMMENT_BODY"`
+
+## Phase 1: Environment Setup and PR Context
+
+### Step 1.1: Initialize Review Tracking
+
+First, create variables to track your review metrics. Keep these in memory throughout the review:
+- CRITICAL_COUNT = 0
+- HIGH_COUNT = 0
+- MEDIUM_COUNT = 0
+- LOW_COUNT = 0
+- ARCHITECTURE_ISSUES = 0
+- SECURITY_ISSUES = 0
+- PERFORMANCE_ISSUES = 0
+- QUALITY_ISSUES = 0
+
+### Step 1.2: Validate Environment
+
+1. Check that PR_NUMBER environment variable is set. If not, exit with error.
+2. Run `gh pr view $PR_NUMBER --json state` to verify the PR exists and is open.
+3. Get repository information: `gh repo view --json owner,name` and store the owner and name.
+4. Get the latest commit SHA: `gh pr view $PR_NUMBER --json commits --jq '.commits[-1].oid'` and store it.
+
+### Step 1.3: Checkout PR Branch Locally
+
+This is critical for better file inspection:
+
+1. Get PR metadata: `gh pr view $PR_NUMBER --json files,title,body,additions,deletions,baseRefName,headRefName > pr_info.json`
+2. Extract branch names from pr_info.json using jq
+3. Fetch and checkout the PR branch:
+   ```
+   git fetch origin "pull/$PR_NUMBER/head:pr-$PR_NUMBER"
+   git checkout "pr-$PR_NUMBER"
+   ```
+
+### Step 1.4: Get Changed Files and Diffs
+
+Use git locally for much faster analysis:
+
+1. Get list of changed files: `git diff --name-only "origin/$BASE_BRANCH" > changed_files.txt`
+2. Get the full diff: `git diff "origin/$BASE_BRANCH" > pr_diff.txt`
+3. Get detailed file changes with status: `git diff --name-status "origin/$BASE_BRANCH" > file_changes.txt`
+
+### Step 1.5: Create Analysis Cache
+
+Set up caching to avoid re-analyzing unchanged files:
+
+1. Create directory: `.claude-review-cache`
+2. Clean old cache entries: Find and delete any .cache files older than 7 days
+3. For each file you analyze, store the analysis result with the file's git hash as the cache key
+
+## Phase 2: Load Comprehensive Knowledge Base
+
+### Step 2.1: Set Up Knowledge Directories
+
+1. Create `.claude-knowledge-cache` directory for caching downloaded knowledge
+2. Check if `../comfy-claude-prompt-library` exists locally. If it does, use it for faster access.
+
+### Step 2.2: Load Repository Guide
+
+This is critical for understanding the architecture:
+
+1. Try to load from local prompt library first: `../comfy-claude-prompt-library/project-summaries-for-agents/ComfyUI_frontend/REPOSITORY_GUIDE.md`
+2. If not available locally, download from: `https://raw.githubusercontent.com/Comfy-Org/comfy-claude-prompt-library/master/project-summaries-for-agents/ComfyUI_frontend/REPOSITORY_GUIDE.md`
+3. Cache the file for future use
+
+### Step 2.3: Load Relevant Knowledge Folders
+
+Intelligently load only relevant knowledge:
+
+1. Use GitHub API to discover available knowledge folders: `https://api.github.com/repos/Comfy-Org/comfy-claude-prompt-library/contents/.claude/knowledge`
+2. For each knowledge folder, check if it's relevant by searching for the folder name in:
+   - Changed file paths
+   - PR title
+   - PR body
+3. If relevant, download all files from that knowledge folder
+
+### Step 2.4: Load Validation Rules
+
+Load specific validation rules:
+
+1. Use GitHub API: `https://api.github.com/repos/Comfy-Org/comfy-claude-prompt-library/contents/.claude/commands/validation`
+2. Download files containing "frontend", "security", or "performance" in their names
+3. Cache all downloaded files
+
+### Step 2.5: Load Local Guidelines
+
+Check for and load:
+1. `CLAUDE.md` in the repository root
+2. `.github/CLAUDE.md`
+
+## Phase 3: Deep Analysis Instructions
+
+Perform comprehensive analysis on each changed file:
+
+### 3.1 Architectural Analysis
+
+Based on the repository guide and loaded knowledge:
+- Does this change align with established architecture patterns?
+- Are domain boundaries respected?
+- Is the extension system used appropriately?
+- Are components properly organized by feature?
+- Does it follow the established service/composable/store patterns?
+
+### 3.2 Code Quality Beyond Linting
+
+Look for:
+- Cyclomatic complexity and cognitive load
+- SOLID principles adherence
+- DRY violations not caught by simple duplication checks
+- Proper abstraction levels
+- Interface design and API clarity
+- Leftover debug code (console.log, commented code, TODO comments)
+
+### 3.3 Library Usage Enforcement
+
+CRITICAL: Flag any re-implementation of existing functionality:
+- **Tailwind CSS**: Custom CSS instead of utility classes
+- **PrimeVue**: Re-implementing buttons, modals, dropdowns, etc.
+- **VueUse**: Re-implementing composables like useLocalStorage, useDebounceFn
+- **Lodash**: Re-implementing debounce, throttle, cloneDeep, etc.
+- **Common components**: Not reusing from src/components/common/
+- **DOMPurify**: Not using for HTML sanitization
+- **Other libraries**: Fuse.js, Marked, Pinia, Zod, Tiptap, Xterm.js, Axios
+
+### 3.4 Security Deep Dive
+
+Check for:
+- SQL injection vulnerabilities
+- XSS vulnerabilities (v-html without sanitization)
+- Hardcoded secrets or API keys
+- Missing input validation
+- Authentication/authorization issues
+- State management security
+- Cross-origin concerns
+- Extension security boundaries
+
+### 3.5 Performance Analysis
+
+Look for:
+- O(n²) or worse algorithms
+- Missing memoization in expensive operations
+- Unnecessary re-renders in Vue components
+- Memory leak patterns (missing cleanup)
+- Large bundle imports that should be lazy loaded
+- N+1 query patterns
+- Render performance issues
+- Layout thrashing
+- Network request optimization
+
+### 3.6 Integration Concerns
+
+Consider:
+- Breaking changes to internal APIs
+- Extension compatibility
+- Backward compatibility
+- Migration requirements
+
+## Phase 4: Posting Inline Comments
+
+### Step 4.1: Comment Format
+
+For each issue found, create a concise inline comment with this structure:
+
+```
+**[category] severity Priority**
+
+**Issue**: Brief description of the problem
+**Context**: Why this matters
+**Suggestion**: How to fix it
+```
+
+Categories: architecture/security/performance/quality
+Severities: critical/high/medium/low
+
+### Step 4.2: Posting Comments
+
+For EACH issue:
+
+1. Identify the exact file path and line number
+2. Update your tracking counters (CRITICAL_COUNT, etc.)
+3. Construct the comment body with proper newlines
+4. Execute the gh api command as a SINGLE LINE:
+
+```bash
+gh api --method POST -H "Accept: application/vnd.github+json" -H "X-GitHub-Api-Version: 2022-11-28" /repos/OWNER/REPO/pulls/$PR_NUMBER/comments -f body="$COMMENT_BODY" -f commit_id="COMMIT_SHA" -f path="FILE_PATH" -F line=LINE_NUMBER -f side="RIGHT"
+```
+
+CRITICAL: The entire command must be on one line. Use actual values, not placeholders.
+
+### Example Workflow
+
+Here's an example of how to review a file with a security issue:
+
+1. First, get the repository info:
+   ```bash
+   gh repo view --json owner,name
+   # Output: {"owner":{"login":"Comfy-Org"},"name":"ComfyUI_frontend"}
+   ```
+
+2. Get the commit SHA:
+   ```bash
+   gh pr view $PR_NUMBER --json commits --jq '.commits[-1].oid'
+   # Output: abc123def456
+   ```
+
+3. Find an issue (e.g., SQL injection on line 42 of src/db/queries.js)
+
+4. Post the inline comment:
+   ```bash
+   # First, create the comment body with proper newlines
+   COMMENT_BODY="**[security] critical Priority**
+
+**Issue**: SQL injection vulnerability - user input directly concatenated into query
+**Context**: Allows attackers to execute arbitrary SQL commands
+**Suggestion**: Use parameterized queries or prepared statements"
+   
+   # Then post the comment (as a single line)
+   gh api --method POST -H "Accept: application/vnd.github+json" -H "X-GitHub-Api-Version: 2022-11-28" /repos/Comfy-Org/ComfyUI_frontend/pulls/$PR_NUMBER/comments -f body="$COMMENT_BODY" -f commit_id="abc123def456" -f path="src/db/queries.js" -F line=42 -f side="RIGHT"
+   ```
+
+Repeat this process for every issue you find in the PR.
+
+## Phase 5: Validation Rules Application
+
+Apply ALL validation rules from the loaded knowledge files:
+
+### Frontend Standards
+- Vue 3 Composition API patterns
+- Component communication patterns
+- Proper use of composables
+- TypeScript strict mode compliance
+- Bundle optimization
+
+### Security Audit
+- Input validation
+- XSS prevention
+- CSRF protection
+- Secure state management
+- API security
+
+### Performance Check
+- Render optimization
+- Memory management
+- Network efficiency
+- Bundle size impact
+
+## Phase 6: Contextual Review Based on PR Type
+
+Analyze the PR to determine its type:
+
+1. Extract PR title and body from pr_info.json
+2. Count files, additions, and deletions
+3. Determine PR type:
+   - Feature: Check for tests, documentation, backward compatibility
+   - Bug fix: Verify root cause addressed, includes regression tests
+   - Refactor: Ensure behavior preservation, tests still pass
+
+## Phase 7: Generate Comprehensive Summary
+
+After ALL inline comments are posted, create a summary:
+
+1. Calculate total issues by category and severity
+2. Use `gh pr review $PR_NUMBER --comment` to post a summary with:
+   - Review disclaimer
+   - Issue distribution (counts by severity)
+   - Category breakdown
+   - Key findings for each category
+   - Positive observations
+   - References to guidelines
+   - Next steps
+
+Include in the summary:
+```

+
+---
+*This is a comprehensive automated review. For architectural decisions requiring human judgment, please request additional manual review.*
+```
+
+## Important Guidelines
+
+1. **Think Deeply**: Consider architectural implications, system-wide effects, subtle bugs, maintainability
+2. **Be Specific**: Point to exact lines with concrete suggestions
+3. **Be Constructive**: Focus on improvements, not just problems
+4. **Be Concise**: Keep comments brief and actionable
+5. **No Formatting**: Don't use markdown headers in inline comments
+6. **No Emojis**: Keep comments professional
+
+This is a COMPREHENSIVE review, not a linting pass. Provide the same quality feedback a senior engineer would give after careful consideration.
+
+## Execution Order
+
+1. Phase 1: Setup and checkout PR
+2. Phase 2: Load all relevant knowledge
+3. Phase 3-5: Analyze each changed file thoroughly
+4. Phase 4: Post inline comments as you find issues
+5. Phase 6: Consider PR type for additional checks
+6. Phase 7: Post comprehensive summary ONLY after all inline comments
+
+Remember: Individual inline comments for each issue, then one final summary. Never batch issues into a single comment.

+# Create Frontend Release
+
+This command guides you through creating a comprehensive frontend release with semantic versioning analysis, automated change detection, security scanning, and multi-stage human verification.
+
+<task>
+Create a frontend release with version type: $ARGUMENTS
+
+Expected format: Version increment type and optional description
+Examples:
+- `patch` - Bug fixes only
+- `minor` - New features, backward compatible  
+- `major` - Breaking changes
+- `prerelease` - Alpha/beta/rc releases
+- `patch "Critical security fixes"` - With custom description
+- `minor --skip-changelog` - Skip automated changelog generation
+- `minor --dry-run` - Simulate release without executing
+
+If no arguments provided, the command will always perform prerelease if the current version is prerelease, or patch in other cases. This command will never perform minor or major releases without explicit direction.
+</task>
+
+## Prerequisites
+
+Before starting, ensure:
+- You have push access to the repository
+- GitHub CLI (`gh`) is authenticated  
+- You're on a clean main branch working tree
+- All intended changes are merged to main
+- You understand the scope of changes being released
+
+## Critical Checks Before Starting
+
+### 1. Check Current Version Status
+```bash
+# Get current version and check if it's a pre-release
+CURRENT_VERSION=$(node -p "require('./package.json').version")
+if [[ "$CURRENT_VERSION" =~ ^[0-9]+\.[0-9]+\.[0-9]+- ]]; then
+  echo "⚠️  Current version $CURRENT_VERSION is a pre-release"
+  echo "Consider releasing stable (e.g., 1.24.0-1 → 1.24.0) first"
+fi
+```
+
+### 2. Find Last Stable Release
+```bash
+# Get last stable release tag (no pre-release suffix)
+LAST_STABLE=$(git tag -l "v*" | grep -v "\-" | sort -V | tail -1)
+echo "Last stable release: $LAST_STABLE"
+```
+
+## Configuration Options
+
+**Environment Variables:**
+- `RELEASE_SKIP_SECURITY_SCAN=true` - Skip security audit
+- `RELEASE_AUTO_APPROVE=true` - Skip some confirmation prompts
+- `RELEASE_DRY_RUN=true` - Simulate release without executing
+
+## Release Process
+
+### Step 1: Environment Safety Check
+
+1. Verify clean working directory:
+   ```bash
+   git status --porcelain
+   ```
+2. Confirm on main branch:
+   ```bash
+   git branch --show-current
+   ```
+3. Pull latest changes:
+   ```bash
+   git pull origin main
+   ```
+4. Check GitHub CLI authentication:
+   ```bash
+   gh auth status
+   ```
+5. Verify npm/PyPI publishing access (dry run)
+6. **CONFIRMATION REQUIRED**: Environment ready for release?
+
+### Step 2: Analyze Recent Changes
+
+1. Get current version from package.json
+2. **IMPORTANT**: Determine correct base for comparison:
+   ```bash
+   # If current version is pre-release, use last stable release
+   if [[ "$CURRENT_VERSION" =~ ^[0-9]+\.[0-9]+\.[0-9]+- ]]; then
+     BASE_TAG=$LAST_STABLE
+   else
+     BASE_TAG=$(git describe --tags --abbrev=0)
+   fi
+   ```
+3. Find commits since base release (CRITICAL: use --first-parent):
+   ```bash
+   git log ${BASE_TAG}..HEAD --oneline --no-merges --first-parent
+   ```
+4. Count total commits:
+   ```bash
+   COMMIT_COUNT=$(git log ${BASE_TAG}..HEAD --oneline --no-merges --first-parent | wc -l)
+   echo "Found $COMMIT_COUNT commits since $BASE_TAG"
+   ```
+5. Analyze commits for:
+   - Breaking changes (BREAKING CHANGE, !, feat())
+   - New features (feat:, feature:)
+   - Bug fixes (fix:, bugfix:)
+   - Documentation changes (docs:)
+   - Dependency updates
+6. **VERIFY PR TARGET BRANCHES**:
+   ```bash
+   # Get merged PRs and verify they were merged to main
+   gh pr list --state merged --limit 50 --json number,title,baseRefName,mergedAt | \
+     jq -r '.[] | select(.baseRefName == "main") | "\(.number): \(.title)"'
+   ```
+7. **HUMAN ANALYSIS**: Review change summary and verify scope
+
+### Step 3: Version Preview
+
+**Version Preview:**
+- Current: `${CURRENT_VERSION}`
+- Proposed: Show exact version number
+- **CONFIRMATION REQUIRED**: Proceed with version `X.Y.Z`?
+
+### Step 4: Security and Dependency Audit
+
+1. Run security audit:
+   ```bash
+   npm audit --audit-level moderate
+   ```
+2. Check for known vulnerabilities in dependencies
+3. Scan for hardcoded secrets or credentials:
+   ```bash
+   git log -p ${BASE_TAG}..HEAD | grep -iE "(password|key|secret|token)" || echo "No sensitive data found"
+   ```
+4. Verify no sensitive data in recent commits
+5. **SECURITY REVIEW**: Address any critical findings before proceeding?
+
+### Step 5: Pre-Release Testing
+
+1. Run complete test suite:
+   ```bash
+   npm run test:unit
+   npm run test:component
+   ```
+2. Run type checking:
+   ```bash
+   npm run typecheck
+   ```
+3. Run linting (may have issues with missing packages):
+   ```bash
+   npm run lint || echo "Lint issues - verify if critical"
+   ```
+4. Test build process:
+   ```bash
+   npm run build
+   npm run build:types
+   ```
+5. **QUALITY GATE**: All tests and builds passing?
+
+### Step 6: Breaking Change Analysis
+
+1. Analyze API changes in:
+   - Public TypeScript interfaces
+   - Extension APIs
+   - Component props
+   - CLAUDE.md guidelines
+2. Check for:
+   - Removed public functions/classes
+   - Changed function signatures
+   - Deprecated feature removals
+   - Configuration changes
+3. Generate breaking change summary
+4. **COMPATIBILITY REVIEW**: Breaking changes documented and justified?
+
+### Step 7: Analyze Dependency Updates
+
+1. **Check for dependency version changes:**
+   ```bash
+   # Compare package.json between versions to detect dependency updates
+   PREV_PACKAGE_JSON=$(git show ${BASE_TAG}:package.json 2>/dev/null || echo '{}')
+   CURRENT_PACKAGE_JSON=$(cat package.json)
+   
+   # Extract litegraph versions
+   PREV_LITEGRAPH=$(echo "$PREV_PACKAGE_JSON" | grep -o '"@comfyorg/litegraph": "[^"]*"' | grep -o '[0-9][^"]*' || echo "not found")
+   CURRENT_LITEGRAPH=$(echo "$CURRENT_PACKAGE_JSON" | grep -o '"@comfyorg/litegraph": "[^"]*"' | grep -o '[0-9][^"]*' || echo "not found")
+   
+   echo "Litegraph version change: ${PREV_LITEGRAPH} → ${CURRENT_LITEGRAPH}"
+   ```
+
+2. **Generate litegraph changelog if version changed:**
+   ```bash
+   if [ "$PREV_LITEGRAPH" != "$CURRENT_LITEGRAPH" ] && [ "$PREV_LITEGRAPH" != "not found" ]; then
+     echo "📦 Fetching litegraph changes between v${PREV_LITEGRAPH} and v${CURRENT_LITEGRAPH}..."
+     
+     # Clone or update litegraph repo for changelog analysis
+     if [ ! -d ".temp-litegraph" ]; then
+       git clone https://github.com/comfyanonymous/litegraph.js.git .temp-litegraph
+     else
+       cd .temp-litegraph && git fetch --all && cd ..
+     fi
+     
+     # Get litegraph changelog between versions
+     LITEGRAPH_CHANGES=$(cd .temp-litegraph && git log v${PREV_LITEGRAPH}..v${CURRENT_LITEGRAPH} --oneline --no-merges 2>/dev/null || \
+       git log --oneline --no-merges --since="$(git log -1 --format=%ci ${BASE_TAG})" --until="$(git log -1 --format=%ci HEAD)" 2>/dev/null || \
+       echo "Unable to fetch litegraph changes")
+     
+     # Categorize litegraph changes
+     LITEGRAPH_FEATURES=$(echo "$LITEGRAPH_CHANGES" | grep -iE "(feat|feature|add)" || echo "")
+     LITEGRAPH_FIXES=$(echo "$LITEGRAPH_CHANGES" | grep -iE "(fix|bug)" || echo "")
+     LITEGRAPH_BREAKING=$(echo "$LITEGRAPH_CHANGES" | grep -iE "(break|breaking)" || echo "")
+     LITEGRAPH_OTHER=$(echo "$LITEGRAPH_CHANGES" | grep -viE "(feat|feature|add|fix|bug|break|breaking)" || echo "")
+     
+     # Clean up temp directory
+     rm -rf .temp-litegraph
+     
+     echo "✅ Litegraph changelog extracted"
+   else
+     echo "ℹ️  No litegraph version change detected"
+     LITEGRAPH_CHANGES=""
+   fi
+   ```
+
+3. **Check other significant dependency updates:**
+   ```bash
+   # Extract all dependency changes for major version bumps
+   OTHER_DEP_CHANGES=""
+   
+   # Compare major dependency versions (you can extend this list)
+   MAJOR_DEPS=("vue" "vite" "@vitejs/plugin-vue" "typescript" "pinia")
+   
+   for dep in "${MAJOR_DEPS[@]}"; do
+     PREV_VER=$(echo "$PREV_PACKAGE_JSON" | grep -o "\"$dep\": \"[^\"]*\"" | grep -o '[0-9][^"]*' | head -1 || echo "")
+     CURR_VER=$(echo "$CURRENT_PACKAGE_JSON" | grep -o "\"$dep\": \"[^\"]*\"" | grep -o '[0-9][^"]*' | head -1 || echo "")
+     
+     if [ "$PREV_VER" != "$CURR_VER" ] && [ -n "$PREV_VER" ] && [ -n "$CURR_VER" ]; then
+       # Check if it's a major version change
+       PREV_MAJOR=$(echo "$PREV_VER" | cut -d. -f1 | sed 's/[^0-9]//g')
+       CURR_MAJOR=$(echo "$CURR_VER" | cut -d. -f1 | sed 's/[^0-9]//g')
+       
+       if [ "$PREV_MAJOR" != "$CURR_MAJOR" ]; then
+         OTHER_DEP_CHANGES="${OTHER_DEP_CHANGES}\n- **${dep}**: ${PREV_VER} → ${CURR_VER} (Major version change)"
+       fi
+     fi
+   done
+   ```
+
+### Step 8: Generate Comprehensive Release Notes
+
+1. Extract commit messages since base release:
+   ```bash
+   git log ${BASE_TAG}..HEAD --oneline --no-merges --first-parent > commits.txt
+   ```
+2. **CRITICAL**: Verify PR inclusion by checking merge location:
+   ```bash
+   # For each significant PR mentioned, verify it's on main
+   for PR in ${SIGNIFICANT_PRS}; do
+     COMMIT=$(gh pr view $PR --json mergeCommit -q .mergeCommit.oid)
+     git branch -r --contains $COMMIT | grep -q "origin/main" || \
+       echo "WARNING: PR #$PR not on main branch!"
+   done
+   ```
+3. Create comprehensive release notes including:
+   - **Version Change**: Show version bump details
+   - **Changelog** grouped by type:
+     - 🚀 **Features** (feat:)
+     - 🐛 **Bug Fixes** (fix:)
+     - 💥 **Breaking Changes** (BREAKING CHANGE)
+     - 📚 **Documentation** (docs:)
+     - 🔧 **Maintenance** (chore:, refactor:)
+     - ⬆️ **Dependencies** (deps:, dependency updates)
+       - **Litegraph Changes** (if version updated):
+         - 🚀 Features: ${LITEGRAPH_FEATURES}
+         - 🐛 Bug Fixes: ${LITEGRAPH_FIXES}
+         - 💥 Breaking Changes: ${LITEGRAPH_BREAKING}
+         - 🔧 Other Changes: ${LITEGRAPH_OTHER}
+       - **Other Major Dependencies**: ${OTHER_DEP_CHANGES}
+   - Include PR numbers and links
+   - Add issue references (Fixes #123)
+4. **Save release notes:**
+   ```bash
+   # Save release notes for PR and GitHub release
+   echo "$RELEASE_NOTES" > release-notes-${NEW_VERSION}.md
+   ```
+5. **CONTENT REVIEW**: Release notes clear and comprehensive with dependency details?
+
+### Step 9: Create Version Bump PR
+
+**For standard version bumps (patch/minor/major):**
+```bash
+# Trigger the workflow
+gh workflow run version-bump.yaml -f version_type=${VERSION_TYPE}
+
+# Workflow runs quickly - usually creates PR within 30 seconds
+echo "Workflow triggered. Waiting for PR creation..."
+```
+
+**For releasing a stable version:**
+1. Must manually create branch and update version:
+   ```bash
+   git checkout -b version-bump-${NEW_VERSION}
+   # Edit package.json to remove pre-release suffix
+   git add package.json
+   git commit -m "${NEW_VERSION}"
+   git push origin version-bump-${NEW_VERSION}
+   ```
+
+2. Wait for PR creation (if using workflow) or create manually:
+   ```bash
+   # For workflow-created PRs - wait and find it
+   sleep 30
+   # Look for PR from comfy-pr-bot (not github-actions)
+   PR_NUMBER=$(gh pr list --author comfy-pr-bot --limit 1 --json number --jq '.[0].number')
+   
+   # Verify we got the PR
+   if [ -z "$PR_NUMBER" ]; then
+     echo "PR not found yet. Checking recent PRs..."
+     gh pr list --limit 5 --json number,title,author
+   fi
+   
+   # For manual PRs
+   gh pr create --title "${NEW_VERSION}" \
+     --body-file release-notes-${NEW_VERSION}.md \
+     --label "Release"
+   ```
+3. **Add required sections to PR body:**
+   ```bash
+   # Create PR body with release notes plus required sections
+   cat > pr-body.md << EOF
+   ${RELEASE_NOTES}
+
+   ## Breaking Changes
+   ${BREAKING_CHANGES:-None}
+
+   ## Testing Performed
+   - ✅ Full test suite (unit, component)
+   - ✅ TypeScript compilation
+   - ✅ Linting checks
+   - ✅ Build verification
+   - ✅ Security audit
+
+   ## Distribution Channels
+   - GitHub Release (with dist.zip)
+   - PyPI Package (comfyui-frontend-package)
+   - npm Package (@comfyorg/comfyui-frontend-types)
+
+   ## Post-Release Tasks
+   - [ ] Verify all distribution channels
+   - [ ] Update external documentation
+   - [ ] Monitor for issues
+   EOF
+   ```
+4. Update PR with enhanced description:
+   ```bash
+   gh pr edit ${PR_NUMBER} --body-file pr-body.md
+   ```
+5. **PR REVIEW**: Version bump PR created and enhanced correctly?
+
+### Step 10: Critical Release PR Verification
+
+1. **CRITICAL**: Verify PR has "Release" label:
+   ```bash
+   gh pr view ${PR_NUMBER} --json labels | jq -r '.labels[].name' | grep -q "Release" || \
+     echo "ERROR: Release label missing! Add it immediately!"
+   ```
+2. Check for update-locales commits:
+   ```bash
+   # WARNING: update-locales may add [skip ci] which blocks release workflow!
+   gh pr view ${PR_NUMBER} --json commits | grep -q "skip ci" && \
+     echo "WARNING: [skip ci] detected - release workflow may not trigger!"
+   ```
+3. Verify version number in package.json
+4. Review all changed files
+5. Ensure no unintended changes included
+6. Wait for required PR checks:
+   ```bash
+   gh pr checks ${PR_NUMBER} --watch
+   ```
+7. **FINAL CODE REVIEW**: Release label present and no [skip ci]?
+
+### Step 11: Pre-Merge Validation
+
+1. **Review Requirements**: Release PRs require approval
+2. Monitor CI checks - watch for update-locales
+3. **CRITICAL WARNING**: If update-locales adds [skip ci], the release workflow won't trigger!
+4. Check no new commits to main since PR creation
+5. **DEPLOYMENT READINESS**: Ready to merge?
+
+### Step 12: Execute Release
+
+1. **FINAL CONFIRMATION**: Merge PR to trigger release?
+2. Merge the Release PR:
+   ```bash
+   gh pr merge ${PR_NUMBER} --merge
+   ```
+3. **IMMEDIATELY CHECK**: Did release workflow trigger?
+   ```bash
+   sleep 10
+   gh run list --workflow=release.yaml --limit=1
+   ```
+4. If workflow didn't trigger due to [skip ci]:
+   ```bash
+   echo "ERROR: Release workflow didn't trigger!"
+   echo "Options:"
+   echo "1. Create patch release (e.g., 1.24.1) to trigger workflow"
+   echo "2. Investigate manual release options"
+   ```
+5. If workflow triggered, monitor execution:
+   ```bash
+   WORKFLOW_RUN_ID=$(gh run list --workflow=release.yaml --limit=1 --json databaseId --jq '.[0].databaseId')
+   gh run watch ${WORKFLOW_RUN_ID}
+   ```
+
+### Step 13: Enhance GitHub Release
+
+1. Wait for automatic release creation:
+   ```bash
+   # Wait for release to be created
+   while ! gh release view v${NEW_VERSION} >/dev/null 2>&1; do
+     echo "Waiting for release creation..."
+     sleep 10
+   done
+   ```
+
+2. **Enhance the GitHub release:**
+   ```bash
+   # Update release with our release notes
+   gh release edit v${NEW_VERSION} \
+     --title "🚀 ComfyUI Frontend v${NEW_VERSION}" \
+     --notes-file release-notes-${NEW_VERSION}.md \
+     --latest
+   
+   # Add any additional assets if needed
+   # gh release upload v${NEW_VERSION} additional-assets.zip
+   ```
+
+3. **Verify release details:**
+   ```bash
+   gh release view v${NEW_VERSION}
+   ```
+
+### Step 14: Verify Multi-Channel Distribution
+
+1. **GitHub Release:**
+   ```bash
+   gh release view v${NEW_VERSION} --json assets,body,createdAt,tagName
+   ```
+   - ✅ Check release notes
+   - ✅ Verify dist.zip attachment
+   - ✅ Confirm release marked as latest (for main branch)
+
+2. **PyPI Package:**
+   ```bash
+   # Check PyPI availability (may take a few minutes)
+   for i in {1..10}; do
+     if curl -s https://pypi.org/pypi/comfyui-frontend-package/json | jq -r '.releases | keys[]' | grep -q ${NEW_VERSION}; then
+       echo "✅ PyPI package available"
+       break
+     fi
+     echo "⏳ Waiting for PyPI package... (attempt $i/10)"
+     sleep 30
+   done
+   ```
+
+3. **npm Package:**
+   ```bash
+   # Check npm availability
+   for i in {1..10}; do
+     if npm view @comfyorg/comfyui-frontend-types@${NEW_VERSION} version >/dev/null 2>&1; then
+       echo "✅ npm package available"
+       break
+     fi
+     echo "⏳ Waiting for npm package... (attempt $i/10)"
+     sleep 30
+   done
+   ```
+
+4. **DISTRIBUTION VERIFICATION**: All channels published successfully?
+
+### Step 15: Post-Release Monitoring Setup
+
+1. **Monitor immediate release health:**
+   ```bash
+   # Check for immediate issues
+   gh issue list --label "bug" --state open --limit 5 --json title,number,createdAt
+   
+   # Monitor download metrics (if accessible)
+   gh release view v${NEW_VERSION} --json assets --jq '.assets[].downloadCount'
+   ```
+
+2. **Update documentation tracking:**
+   ```bash
+   cat > post-release-checklist.md << EOF
+   # Post-Release Checklist for v${NEW_VERSION}
+
+   ## Immediate Tasks (Next 24 hours)
+   - [ ] Monitor error rates and user feedback
+   - [ ] Watch for critical issues

+
+### Quality Gates Summary
+
+The command implements multiple quality gates:
+
+1. **🔒 Security Gate**: Vulnerability scanning, secret detection
+2. **🧪 Quality Gate**: Unit and component tests, linting, type checking
+3. **📋 Content Gate**: Changelog accuracy, release notes quality
+4. **🔄 Process Gate**: Release timing verification
+5. **✅ Verification Gate**: Multi-channel publishing confirmation
+6. **📊 Monitoring Gate**: Post-release health tracking
+
+## Common Scenarios
+
+### Scenario 1: Regular Feature Release
+```bash
+/project:create-frontend-release minor
+```
+- Analyzes features since last release
+- Generates changelog automatically
+- Creates comprehensive release notes
+
+### Scenario 2: Critical Security Patch
+```bash
+/project:create-frontend-release patch "Security fixes for CVE-2024-XXXX"
+```
+- Expedited security scanning
+- Enhanced monitoring setup
+
+### Scenario 3: Major Version with Breaking Changes
+```bash
+/project:create-frontend-release major
+```
+- Comprehensive breaking change analysis
+- Migration guide generation
+
+### Scenario 4: Pre-release Testing
+```bash
+/project:create-frontend-release prerelease
+```
+- Creates alpha/beta/rc versions
+- Draft release status
+- Python package specs require that prereleases use alpha/beta/rc as the preid
+
+## Common Issues and Solutions
+
+### Issue: Pre-release Version Confusion
+**Problem**: Not sure whether to promote pre-release or create new version
+**Solution**: 
+- Follow semver standards: a prerelease version is followed by a normal release.  It should have the same major, minor, and patch versions as the prerelease.
+
+### Issue: Wrong Commit Count
+**Problem**: Changelog includes commits from other branches
+**Solution**: Always use `--first-parent` flag with git log
+
+**Update**: Sometimes update-locales doesn't add [skip ci] - always verify!
+
+### Issue: Missing PRs in Changelog
+**Problem**: PR was merged to different branch
+**Solution**: Verify PR merge target with:
+```bash
+gh pr view ${PR_NUMBER} --json baseRefName
+```
+
+### Issue: Incomplete Dependency Changelog
+**Problem**: Litegraph or other dependency updates only show version bump, not actual changes
+**Solution**: The command now automatically:
+- Detects litegraph version changes between releases
+- Clones the litegraph repository temporarily
+- Extracts and categorizes changes between versions
+- Includes detailed litegraph changelog in release notes
+- Cleans up temporary files after analysis
+
+### Issue: Release Failed Due to [skip ci]
+**Problem**: Release workflow didn't trigger after merge
+**Prevention**: Always avoid this scenario
+- Ensure that `[skip ci]` or similar flags are NOT in the `HEAD` commit message of the PR
+  - Push a new, empty commit to the PR
+- Always double-check this immediately before merging
+
+**Recovery Strategy**:
+1. Revert version in a new PR (e.g., 1.24.0 → 1.24.0-1)
+2. Merge the revert PR
+3. Run version bump workflow again
+4. This creates a fresh PR without [skip ci]
+Benefits: Cleaner than creating extra version numbers
+
+## Key Learnings & Notes
+
+1. **PR Author**: Version bump PRs are created by `comfy-pr-bot`, not `github-actions`
+2. **Workflow Speed**: Version bump workflow typically completes in ~20-30 seconds
+3. **Update-locales Behavior**: Inconsistent - sometimes adds [skip ci], sometimes doesn't
+4. **Recovery Options**: Reverting version is cleaner than creating extra versions
+5. **Dependency Tracking**: Command now automatically includes litegraph and major dependency changes in changelogs
+6. **Litegraph Integration**: Temporary cloning of litegraph repo provides detailed change analysis between versions

+# Create Hotfix Release
+
+This command guides you through creating a patch/hotfix release for ComfyUI Frontend with comprehensive safety checks and human confirmations at each step.
+
+<task>
+Create a hotfix release by cherry-picking commits or PR commits from main to a core branch: $ARGUMENTS
+
+Expected format: Comma-separated list of commits or PR numbers
+Examples: 
+- `abc123,def456,ghi789` (commits)
+- `#1234,#5678` (PRs)
+- `abc123,#1234,def456` (mixed)
+
+If no arguments provided, the command will help identify the correct core branch and guide you through selecting commits/PRs.
+</task>
+
+## Prerequisites
+
+Before starting, ensure:
+- You have push access to the repository
+- GitHub CLI (`gh`) is authenticated
+- You're on a clean working tree
+- You understand the commits/PRs you're cherry-picking
+
+## Hotfix Release Process
+
+### Step 1: Identify Target Core Branch
+
+1. Fetch the current ComfyUI requirements.txt from master branch:
+   ```bash
+   curl -s https://raw.githubusercontent.com/comfyanonymous/ComfyUI/master/requirements.txt | grep "comfyui-frontend-package"
+   ```
+2. Extract the `comfyui-frontend-package` version (e.g., `comfyui-frontend-package==1.23.4`)
+3. Parse version to get major.minor (e.g., `1.23.4` → `1.23`)
+4. Determine core branch: `core/<major>.<minor>` (e.g., `core/1.23`)
+5. Verify the core branch exists: `git ls-remote origin refs/heads/core/*`
+6. **CONFIRMATION REQUIRED**: Is `core/X.Y` the correct target branch?
+
+### Step 2: Parse and Validate Arguments
+
+1. Parse the comma-separated list of commits/PRs
+2. For each item:
+   - If starts with `#`: Treat as PR number
+   - Otherwise: Treat as commit hash
+3. For PR numbers:
+   - Fetch PR details using `gh pr view <number>`
+   - Extract the merge commit if PR is merged
+   - If PR has multiple commits, list them all
+   - **CONFIRMATION REQUIRED**: Use merge commit or cherry-pick individual commits?
+4. Validate all commit hashes exist in the repository
+
+### Step 3: Analyze Target Changes
+
+1. For each commit/PR to cherry-pick:
+   - Display commit hash, author, date
+   - Show PR title and number (if applicable)
+   - Display commit message
+   - Show files changed and diff statistics
+   - Check if already in core branch: `git branch --contains <commit>`
+2. Identify potential conflicts by checking changed files
+3. **CONFIRMATION REQUIRED**: Proceed with these commits?
+
+### Step 4: Create Hotfix Branch
+
+1. Checkout the core branch (e.g., `core/1.23`)
+2. Pull latest changes: `git pull origin core/X.Y`
+3. Display current version from package.json
+4. Create hotfix branch: `hotfix/<version>-<timestamp>`
+   - Example: `hotfix/1.23.4-20241120`
+5. **CONFIRMATION REQUIRED**: Created branch correctly?
+
+### Step 5: Cherry-pick Changes
+
+For each commit:
+1. Attempt cherry-pick: `git cherry-pick <commit>`
+2. If conflicts occur:
+   - Display conflict details
+   - Show conflicting sections
+   - Provide resolution guidance
+   - **CONFIRMATION REQUIRED**: Conflicts resolved correctly?
+3. After successful cherry-pick:
+   - Show the changes: `git show HEAD`
+   - Run validation: `npm run typecheck && npm run lint`
+4. **CONFIRMATION REQUIRED**: Cherry-pick successful and valid?
+
+### Step 6: Create PR to Core Branch
+
+1. Push the hotfix branch: `git push origin hotfix/<version>-<timestamp>`
+2. Create PR using gh CLI:
+   ```bash
+   gh pr create --base core/X.Y --head hotfix/<version>-<timestamp> \
+     --title "[Hotfix] Cherry-pick fixes to core/X.Y" \
+     --body "Cherry-picked commits: ..."
+   ```
+3. Add appropriate labels (but NOT "Release" yet)
+4. PR body should include:
+   - List of cherry-picked commits/PRs
+   - Original issue references
+   - Testing instructions
+   - Impact assessment
+5. **CONFIRMATION REQUIRED**: PR created correctly?
+
+### Step 7: Wait for Tests
+
+1. Monitor PR checks: `gh pr checks`
+2. Display test results as they complete
+3. If any tests fail:
+   - Show failure details
+   - Analyze if related to cherry-picks
+   - **DECISION REQUIRED**: Fix and continue, or abort?
+4. Wait for all required checks to pass
+5. **CONFIRMATION REQUIRED**: All tests passing?
+
+### Step 8: Merge Hotfix PR
+
+1. Verify all checks have passed
+2. Check for required approvals
+3. Merge the PR: `gh pr merge --merge`
+4. Delete the hotfix branch
+5. **CONFIRMATION REQUIRED**: PR merged successfully?
+
+### Step 9: Create Version Bump
+
+1. Checkout the core branch: `git checkout core/X.Y`
+2. Pull latest changes: `git pull origin core/X.Y`
+3. Read current version from package.json
+4. Determine patch version increment:
+   - Current: `1.23.4` → New: `1.23.5`
+5. Create release branch named with new version: `release/1.23.5`
+6. Update version in package.json to `1.23.5`
+7. Commit: `git commit -m "[release] Bump version to 1.23.5"`
+8. **CONFIRMATION REQUIRED**: Version bump correct?
+
+### Step 10: Create Release PR
+
+1. Push release branch: `git push origin release/1.23.5`
+2. Create PR with Release label:
+   ```bash
+   gh pr create --base core/X.Y --head release/1.23.5 \
+     --title "[Release] v1.23.5" \
+     --body "..." \
+     --label "Release"
+   ```
+3. **CRITICAL**: Verify "Release" label is added
+4. PR description should include:
+   - Version: `1.23.4` → `1.23.5`
+   - Included fixes (link to previous PR)
+   - Release notes for users
+5. **CONFIRMATION REQUIRED**: Release PR has "Release" label?
+
+### Step 11: Monitor Release Process
+
+1. Wait for PR checks to pass
+2. **FINAL CONFIRMATION**: Ready to trigger release by merging?
+3. Merge the PR: `gh pr merge --merge`
+4. Monitor release workflow:
+   ```bash
+   gh run list --workflow=release.yaml --limit=1
+   gh run watch
+   ```
+5. Track progress:
+   - GitHub release draft/publication
+   - PyPI upload
+   - npm types publication
+
+### Step 12: Post-Release Verification
+
+1. Verify GitHub release:
+   ```bash
+   gh release view v1.23.5
+   ```
+2. Check PyPI package:
+   ```bash
+   pip index versions comfyui-frontend-package | grep 1.23.5
+   ```
+3. Verify npm package:
+   ```bash
+   npm view @comfyorg/comfyui-frontend-types@1.23.5
+   ```
+4. Generate release summary with:
+   - Version released
+   - Commits included
+   - Issues fixed
+   - Distribution status
+5. **CONFIRMATION REQUIRED**: Release completed successfully?
+
+## Safety Checks
+
+Throughout the process:
+- Always verify core branch matches ComfyUI's requirements.txt
+- For PRs: Ensure using correct commits (merge vs individual)
+- Check version numbers follow semantic versioning
+- **Critical**: "Release" label must be on version bump PR
+- Validate cherry-picks don't break core branch stability
+- Keep audit trail of all operations
+
+## Rollback Procedures
+
+If something goes wrong:
+- Before push: `git reset --hard origin/core/X.Y`
+- After PR creation: Close PR and start over
+- After failed release: Create new patch version with fixes
+- Document any issues for future reference
+
+## Important Notes
+
+- Core branch version will be behind main - this is expected
+- The "Release" label triggers the PyPI/npm publication
+- PR numbers must include the `#` prefix
+- Mixed commits/PRs are supported but review carefully
+- Always wait for full test suite before proceeding
+
+## Expected Timeline
+
+- Step 1-3: ~10 minutes (analysis)
+- Steps 4-6: ~15-30 minutes (cherry-picking)
+- Step 7: ~10-20 minutes (tests)
+- Steps 8-10: ~10 minutes (version bump)
+- Step 11-12: ~15-20 minutes (release)
+- Total: ~60-90 minutes
+
+This process ensures a safe, verified hotfix release with multiple confirmation points and clear tracking of what changes are being released.

+# ComfyUI Frontend - Claude Review Context
+
+This file provides additional context for the automated PR review system.
+
+## Quick Reference
+
+### PrimeVue Component Migrations
+
+When reviewing, flag these deprecated components:
+- `Dropdown` → Use `Select` from 'primevue/select'
+- `OverlayPanel` → Use `Popover` from 'primevue/popover'
+- `Calendar` → Use `DatePicker` from 'primevue/datepicker'
+- `InputSwitch` → Use `ToggleSwitch` from 'primevue/toggleswitch'
+- `Sidebar` → Use `Drawer` from 'primevue/drawer'
+- `Chips` → Use `AutoComplete` with multiple enabled and typeahead disabled
+- `TabMenu` → Use `Tabs` without panels
+- `Steps` → Use `Stepper` without panels
+- `InlineMessage` → Use `Message` component
+
+### API Utilities Reference
+
+- `api.apiURL()` - Backend API calls (/prompt, /queue, /view, etc.)
+- `api.fileURL()` - Static file access (templates, extensions)
+- `$t()` / `i18n.global.t()` - Internationalization
+- `DOMPurify.sanitize()` - HTML sanitization
+
+## Review Scope
+
+This automated review performs comprehensive analysis including:
+- Architecture and design patterns
+- Security vulnerabilities
+- Performance implications
+- Code quality and maintainability
+- Integration concerns
+
+For implementation details, see `.claude/commands/comprehensive-pr-review.md`.

-- When referencing PrimeVue, you can get all the docs here: https://primevue.org. Do this instead of making up or inferring names of Components
-- When trying to set tailwind classes for dark theme, use "dark-theme:" prefix rather than "dark:"
-- Never add lines to PR descriptions that say "Generated with Claude Code"
-- When making PR names and commit messages, if you are going to add a prefix like "docs:", "feat:", "bugfix:", use square brackets around the prefix term and do not use a colon (e.g., should be "[docs]" rather than "docs:").
-- When I reference GitHub Repos related to Comfy-Org, you should proactively fetch or read the associated information in the repo. To do so, you should exhaust all options: (1) Check if we have a local copy of the repo, (2) Use the GitHub API to fetch the information; you may want to do this IN ADDITION to the other options, especially for reading speicifc branches/PRs/comments/reviews/metadata, and (3) curl the GitHub website and parse the html or json responses
-- For information about ComfyUI, ComfyUI_frontend, or ComfyUI-Manager, you can web search or download these wikis: https://deepwiki.com/Comfy-Org/ComfyUI-Manager, https://deepwiki.com/Comfy-Org/ComfyUI_frontend/1-overview, https://deepwiki.com/comfyanonymous/ComfyUI/2-core-architecture
-- If a question/project is related to Comfy-Org, Comfy, or ComfyUI ecosystem, you should proactively use the Comfy docs to answer the question. The docs may be referenced with URLs like https://docs.comfy.org
-- When operating inside a repo, check for README files at key locations in the repo detailing info about the contents of that folder. E.g., top-level key folders like tests-ui, browser_tests, composables, extensions/core, stores, services often have their own README.md files. When writing code, make sure to frequently reference these README files to understand the overall architecture and design of the project. Pay close attention to the snippets to learn particular patterns that seem to be there for a reason, as you should emulate those.
-- Prefer running single tests, and not the whole test suite, for performance
-- If using a lesser known or complex CLI tool, run the --help to see the documentation before deciding what to run, even if just for double-checking or verifying things.
-- IMPORTANT: the most important goal when writing code is to create clean, best-practices, sustainable, and scalable public APIs and interfaces. Our app is used by thousands of users and we have thousands of mods/extensions that are constantly changing and updating; and we are also always updating. That's why it is IMPORTANT that we design systems and write code that follows practices of domain-driven design, object-oriented design, and design patterns (such that you can assure stability while allowing for all components around you to change and evolve). We ABSOLUTELY prioritize clean APIs and public interfaces that clearly define and restrict how/what the mods/extensions can access.
-- If any of these technologies are referenced, you can proactively read their docs at these locations: https://primevue.org/theming, https://primevue.org/forms/, https://www.electronjs.org/docs/latest/api/browser-window, https://vitest.dev/guide/browser/, https://atlassian.design/components/pragmatic-drag-and-drop/core-package/drop-targets/, https://playwright.dev/docs/api/class-test, https://playwright.dev/docs/api/class-electron, https://www.algolia.com/doc/api-reference/rest-api/, https://pyav.org/docs/develop/cookbook/basics.html
-- IMPORTANT: Never add Co-Authored by Claude or any refrence to Claude or Claude Code in commit messages, PR descriptions, titles, or any documentation whatsoever
-- The npm script to type check is called "typecheck" NOT "type check"
-- Use the Vue 3 Composition API instead of the Options API when writing Vue components. An exception is when overriding or extending a PrimeVue component for compatibility, you may use the Options API.
-- when we are solving an issue we know the link/number for, we should add "Fixes #n" (where n is the issue number) to the PR description.
-- Never write css if you can accomplish the same thing with tailwind utility classes
-- Use setup() function for component logic
-- Utilize ref and reactive for reactive state
-- Implement computed properties with computed()
-- Use watch and watchEffect for side effects
-- Implement lifecycle hooks with onMounted, onUpdated, etc.
-- Utilize provide/inject for dependency injection
-- Use vue 3.5 style of default prop declaration. Do not define a `props` variable; instead, destructure props. Since vue 3.5, destructuring props does not strip them of reactivity.
-- Use Tailwind CSS for styling
-- Leverage VueUse functions for performance-enhancing styles
-- Use lodash for utility functions
-- Use TypeScript for type safety
-- Implement proper props and emits definitions
-- Utilize Vue 3's Teleport component when needed
-- Use Suspense for async components
-- Implement proper error handling
-- Follow Vue 3 style guide and naming conventions
-- Use Vite for fast development and building
-- Use vue-i18n in composition API for any string literals. Place new translation entries in src/locales/en/main.json.
-- Avoid using `@ts-expect-error` to work around type issues. We needed to employ it to migrate to TypeScript, but it should not be viewed as an accepted practice or standard.

 This document outlines the setup, usage, and common patterns for Playwright browser tests in the ComfyUI_frontend project.
 
-## WARNING
+## Prerequisites
 
-The browser tests will change the ComfyUI backend state, such as user settings and saved workflows.
-If `TEST_COMFYUI_DIR` in `.env` isn't set to your `(Comfy Path)/ComfyUI` directory, these changes won't be automatically restored.
+**CRITICAL**: Start ComfyUI backend with `--multi-user` flag:
+
+```bash
+python main.py --multi-user
+```
+
+Without this flag, parallel tests will conflict and fail randomly.
 
 ## Setup
 
 ### ComfyUI devtools
+
 Clone <https://github.com/Comfy-Org/ComfyUI_devtools> to your `custom_nodes` directory.  
 _ComfyUI_devtools adds additional API endpoints and nodes to ComfyUI for browser testing._
 
 ### Node.js & Playwright Prerequisites
-Ensure you have Node.js v20 or later installed. Then, set up the Chromium test driver:
+
+Ensure you have Node.js v20 or v22 installed. Then, set up the Chromium test driver:
+
 ```bash
 npx playwright install chromium --with-deps
 ```
 
-### Environment Variables
-Ensure the environment variables in `.env` are set correctly according to your setup. 
+### Environment Configuration
 
-The `.env` file will not exist until you create it yourself.
+Create `.env` from the template:
 
-A template with helpful information can be found in `.env_example`.
+```bash
+cp .env_example .env
+```
 
-### Multiple Tests
-If you are running Playwright tests in parallel or running the same test multiple times, the flag `--multi-user` must be added to the main ComfyUI process.
+Key settings for debugging:
+
+```bash
+# Remove Vue dev overlay that blocks UI elements
+DISABLE_VUE_PLUGINS=true
+
+# Test against dev server (recommended) or backend directly
+PLAYWRIGHT_TEST_URL=http://localhost:5173  # Dev server
+# PLAYWRIGHT_TEST_URL=http://localhost:8188  # Direct backend
+
+# Path to ComfyUI for backing up user data/settings before tests
+TEST_COMFYUI_DIR=/path/to/your/ComfyUI
+```
+
+### Common Setup Issues
+
+**Most tests require the new menu system** - Add to your test:
+
+```typescript
+test.beforeEach(async ({ comfyPage }) => {
+  await comfyPage.setSetting('Comfy.UseNewMenu', 'Top')
+})
+```
+
+### Release API Mocking
+
+By default, all tests mock the release API (`api.comfy.org/releases`) to prevent release notification popups from interfering with test execution. This is necessary because the release notifications can appear over UI elements and block test interactions.
+
+To test with real release data, you can disable mocking:
+
+```typescript
+await comfyPage.setup({ mockReleases: false })
+```
+
+For tests that specifically need to test release functionality, see the example in `tests/releaseNotifications.spec.ts`.
 
 ## Running Tests
 
-There are multiple ways to run the tests:
+**Always use UI mode for development:**
 
-1. **Headless mode with report generation:**
-   ```bash
-   npx playwright test
-   ```
-   This runs all tests without a visible browser and generates a comprehensive test report.
+```bash
+npx playwright test --ui
+```
 
-2. **UI mode for interactive testing:**
-   ```bash
-   npx playwright test --ui
-   ```
-   This opens a user interface where you can select specific tests to run and inspect the test execution timeline.
+UI mode features:
 
-   ![Playwright UI Mode](https://github.com/user-attachments/assets/6a1ebef0-90eb-4157-8694-f5ee94d03755)
+- **Locator picker**: Click the target icon, then click any element to get the exact locator code to use in your test. The code appears in the _Locator_ tab.
+- **Step debugging**: Step through your test line-by-line by clicking _Source_ tab
+- **Time travel**: In the _Actions_ tab/panel, click any step to see the browser state at that moment
+- **Console/Network Tabs**: View logs and API calls at each step
+- **Attachments Tab**: View all snapshots with expected and actual images
 
-3. **Running specific tests:**
-   ```bash
-   npx playwright test widget.spec.ts
-   ```
+![Playwright UI Mode](https://github.com/user-attachments/assets/c158c93f-b39a-44c5-a1a1-e0cc975ee9f2)
+
+For CI or headless testing:
+
+```bash
+npx playwright test                    # Run all tests
+npx playwright test widget.spec.ts     # Run specific test file
+```
+
+### Local Development Config
+
+For debugging, you can try adjusting these settings in `playwright.config.ts`:
+
+```typescript
+export default defineConfig({
+  // VERY HELPFUL: Skip screenshot tests locally
+  grep: process.env.CI ? undefined : /^(?!.*screenshot).*$/
+
+  retries: 0, // No retries while debugging. Increase if writing new tests. that may be flaky.
+  workers: 1, // Single worker for easier debugging. Increase to match CPU cores if you want to run a lot of tests in parallel.
+  timeout: 30000, // Longer timeout for breakpoints
+
+  use: {
+    trace: 'on', // Always capture traces (CI uses 'on-first-retry')
+    video: 'on' // Always record video (CI uses 'retain-on-failure')
+  },
+
+})

 Browser tests in this project follow a specific organization pattern:
 
 - **Fixtures**: Located in `fixtures/` - These provide test setup and utilities
+
   - `ComfyPage.ts` - The main fixture for interacting with ComfyUI
   - `ComfyMouse.ts` - Utility for mouse interactions with the canvas
   - Components fixtures in `fixtures/components/` - Page object models for UI components
 
 - **Tests**: Located in `tests/` - The actual test specifications
+
   - Organized by functionality (e.g., `widget.spec.ts`, `interaction.spec.ts`)
   - Snapshot directories (e.g., `widget.spec.ts-snapshots/`) contain reference screenshots

 1. **Focus elements explicitly**:
    Canvas-based elements often need explicit focus before interaction:
+
    ```typescript
    // Click the canvas first to focus it before pressing keys
-   await comfyPage.canvas.click();
-   await comfyPage.page.keyboard.press('a');
+   await comfyPage.canvas.click()
+   await comfyPage.page.keyboard.press('a')
    ```
 
 2. **Mark canvas as dirty if needed**:
    Some interactions need explicit canvas updates:
+
    ```typescript
    // After programmatically changing node state, mark canvas dirty
    await comfyPage.page.evaluate(() => {
-     window['app'].graph.setDirtyCanvas(true, true);
-   });
+     window['app'].graph.setDirtyCanvas(true, true)
+   })
    ```
 
-3. **Use node references over coordinates**: 
+3. **Use node references over coordinates**:
    Node references from `fixtures/utils/litegraphUtils.ts` provide stable ways to interact with nodes:
+
    ```typescript
    // Prefer this:
-   const node = await comfyPage.getNodeRefsByType('LoadImage')[0];
-   await node.click('title');
-   
+   const node = await comfyPage.getNodeRefsByType('LoadImage')[0]
+   await node.click('title')
+
    // Over this:
-   await comfyPage.canvas.click({ position: { x: 100, y: 100 } });
+   await comfyPage.canvas.click({ position: { x: 100, y: 100 } })
    ```
 
 4. **Wait for canvas to render after UI interactions**:
+
    ```typescript
-   await comfyPage.nextFrame();
+   await comfyPage.nextFrame()
    ```
 
 5. **Clean up persistent server state**:
    While most state is reset between tests, anything stored on the server persists:
+
    ```typescript
    // Reset settings that affect other tests (these are stored on server)
-   await comfyPage.setSetting('Comfy.ColorPalette', 'dark');
-   await comfyPage.setSetting('Comfy.NodeBadge.NodeIdBadgeMode', 'None');
-   
+   await comfyPage.setSetting('Comfy.ColorPalette', 'dark')
+   await comfyPage.setSetting('Comfy.NodeBadge.NodeIdBadgeMode', 'None')
+
    // Clean up uploaded files if needed
-   await comfyPage.request.delete(`${comfyPage.url}/api/delete/image.png`);
+   await comfyPage.request.delete(`${comfyPage.url}/api/delete/image.png`)
    ```
 
 6. **Prefer functional assertions over screenshots**:
    Use screenshots only when visual verification is necessary:
+
    ```typescript
    // Prefer this:
-   expect(await node.isPinned()).toBe(true);
-   expect(await node.getProperty('title')).toBe('Expected Title');
-   
+   expect(await node.isPinned()).toBe(true)
+   expect(await node.getProperty('title')).toBe('Expected Title')
+
    // Over this - only use when needed:
-   await expect(comfyPage.canvas).toHaveScreenshot('state.png');
+   await expect(comfyPage.canvas).toHaveScreenshot('state.png')
    ```
 
 7. **Use minimal test workflows**:
    When creating test workflows, keep them as minimal as possible:
+
    ```typescript
    // Include only the components needed for the test
-   await comfyPage.loadWorkflow('single_ksampler');
+   await comfyPage.loadWorkflow('single_ksampler')
    ```
 
+8. **Debug helpers for visual debugging** (remove before committing):
+
+   ComfyPage includes temporary debug methods for troubleshooting:
+
+   ```typescript
+   test('debug failing interaction', async ({ comfyPage }, testInfo) => {
+     // Add visual markers to see click positions
+     await comfyPage.debugAddMarker({ x: 100, y: 200 })
+
+     // Attach screenshot with markers to test report
+     await comfyPage.debugAttachScreenshot(testInfo, 'node-positions', {
+       element: 'canvas',
+       markers: [{ position: { x: 100, y: 200 } }]
+     })
+
+     // Show canvas overlay for easier debugging
+     await comfyPage.debugShowCanvasOverlay()
+
+     // Remember to remove debug code before committing!
+   })
+   ```
+
+   Available debug methods:
+
+   - `debugAddMarker(position)` - Red circle at position
+   - `debugAttachScreenshot(testInfo, name)` - Attach to test report
+   - `debugShowCanvasOverlay()` - Show canvas as overlay
+   - `debugGetCanvasDataURL()` - Get canvas as base64

-## Screenshot Expectations
+## Screenshot Testing
 
 Due to variations in system font rendering, screenshot expectations are platform-specific. Please note:
 
-- **DO NOT commit local screenshot expectations** to the repository
+- **Do not commit local screenshot expectations** to the repository
 - We maintain Linux screenshot expectations as our GitHub Action runner operates in a Linux environment
 - While developing, you can generate local screenshots for your tests, but these will differ from CI-generated ones
 
-To set new test expectations for PR:
+### Working with Screenshots Locally
 
-1. Write your test with screenshot assertions using `toHaveScreenshot(filename)`
-2. Create a pull request from a `Comfy-Org/ComfyUI_frontend` branch
-3. Add the `New Browser Test Expectation` tag to your pull request
-4. The GitHub CI will automatically generate and commit the reference screenshots
+Option 1 - Skip screenshot tests (add to `playwright.config.ts`):
 
-This approach ensures consistent screenshot expectations across all PRs and avoids issues with platform-specific rendering.
+```typescript
+export default defineConfig({
+  grep: process.env.CI ? undefined : /^(?!.*screenshot).*$/
+})
+```
 
-> **Note:** If you're making a pull request from a forked repository, the GitHub action won't be able to commit updated screenshot expectations directly to your PR branch.
+Option 2 - Generate local baselines for comparison:
+
+```bash
+npx playwright test --update-snapshots
+```
+
+### Getting Test Artifacts from GitHub Actions
+
+When tests fail in CI, you can download screenshots and traces:
+
+1. Go to the failed workflow run in GitHub Actions
+2. Scroll to "Artifacts" section at the bottom
+3. Download `playwright-report` or `test-results`
+4. Extract and open the HTML report locally
+5. View actual vs expected screenshots and execution traces
+
+### Creating New Screenshot Baselines
+
+For PRs from `Comfy-Org/ComfyUI_frontend` branches:
+
+1. Write test with `toHaveScreenshot('filename.png')`
+2. Create PR and add `New Browser Test Expectation` label
+3. CI will generate and commit the Linux baseline screenshots
+
+> **Note:** Fork PRs cannot auto-commit screenshots. A maintainer will need to commit the screenshots manually for you (don't worry, they'll do it).
