+## Component Details
+
+### 1. Release Pipeline (release.yml)
+
+#### Purpose
+Fast publication of Python package and GitHub release.
+
+#### Input
+- **Trigger**: Git tag matching `v*` (excluding `test-v*`)
+- **Example**: `v1.2.3`
+
+#### Processing Stages
+
+##### Stage 1: Version Extraction
+```bash
+Input:  refs/tags/v1.2.3
+Output: VERSION=1.2.3
+```
+
+**Implementation**:
+```bash
+TAG_VERSION=${GITHUB_REF#refs/tags/v}  # Remove 'refs/tags/v' prefix
+echo "VERSION=$TAG_VERSION" >> $GITHUB_OUTPUT
+```
+
+##### Stage 2: Version Validation
+```bash
+Input:  TAG_VERSION=1.2.3
+Check:  crawl4ai/__version__.py contains __version__ = "1.2.3"
+Output: Pass/Fail
+```
+
+**Implementation**:
+```bash
+PACKAGE_VERSION=$(python -c "from crawl4ai.__version__ import __version__; print(__version__)")
+if [ "$TAG_VERSION" != "$PACKAGE_VERSION" ]; then
+  exit 1
+fi
+```
+
+##### Stage 3: Package Build
+```bash
+Input:  Source code + pyproject.toml
+Output: dist/crawl4ai-1.2.3.tar.gz
+        dist/crawl4ai-1.2.3-py3-none-any.whl
+```
+
+**Implementation**:
+```bash
+python -m build
+# Uses build backend defined in pyproject.toml
+```
+
+##### Stage 4: PyPI Upload
+```bash
+Input:  dist/*.{tar.gz,whl}
+Auth:   PYPI_TOKEN
+Output: Package published to PyPI
+```
+
+**Implementation**:
+```bash
+twine upload dist/*
+# Environment:
+#   TWINE_USERNAME: __token__
+#   TWINE_PASSWORD: ${{ secrets.PYPI_TOKEN }}
+```
+
+##### Stage 5: GitHub Release Creation
+```bash
+Input:  Tag: v1.2.3
+        Body: Markdown content
+Output: Published GitHub release
+```
+
+**Implementation**:
+```yaml
+uses: softprops/action-gh-release@v2
+with:
+  tag_name: v1.2.3
+  name: Release v1.2.3
+  body: |
+    Installation instructions and changelog
+  draft: false
+  prerelease: false
+```
+
+#### Output
+- **PyPI Package**: https://pypi.org/project/crawl4ai/1.2.3/
+- **GitHub Release**: Published release on repository
+- **Event**: `release.published` (triggers Docker workflow)
+
+#### Timeline
+```
+0:00 - Tag pushed
+0:01 - Checkout + Python setup
+0:02 - Version validation
+0:03 - Package build
+0:04 - PyPI upload starts
+0:06 - PyPI upload complete
+0:07 - GitHub release created
+0:08 - Workflow complete
+```
+
+---
+
+### 2. Docker Release Pipeline (docker-release.yml)
+
+#### Purpose
+Build and publish multi-architecture Docker images.
+
+#### Inputs
+
+##### Input 1: Release Event (Automatic)
+```yaml
+Event: release.published
+Data:  github.event.release.tag_name = "v1.2.3"
+```
+
+##### Input 2: Docker Rebuild Tag (Manual)
+```yaml
+Tag: docker-rebuild-v1.2.3
+```
+
+#### Processing Stages
+
+##### Stage 1: Version Detection
+```bash
+# From release event:
+VERSION = github.event.release.tag_name.strip("v")
+# Result: "1.2.3"
+
+# From rebuild tag:
+VERSION = GITHUB_REF.replace("refs/tags/docker-rebuild-v", "")
+# Result: "1.2.3"
+```
+
+##### Stage 2: Semantic Version Parsing
+```bash
+Input:  VERSION=1.2.3
+Output: MAJOR=1
+        MINOR=1.2
+        PATCH=3 (implicit)
+```
+
+**Implementation**:
+```bash
+MAJOR=$(echo $VERSION | cut -d. -f1)    # Extract first component
+MINOR=$(echo $VERSION | cut -d. -f1-2)  # Extract first two components
+```
+
+##### Stage 3: Multi-Architecture Setup
+```yaml
+Setup:
+  - Docker Buildx (multi-platform builder)
+  - QEMU (ARM emulation on x86)
+
+Platforms:
+  - linux/amd64 (x86_64)
+  - linux/arm64 (aarch64)
+```
+
+**Architecture**:
+```
+GitHub Runner (linux/amd64)
+  ├─ Buildx Builder
+  │   ├─ Native: Build linux/amd64 image
+  │   └─ QEMU: Emulate ARM to build linux/arm64 image
+  └─ Generate manifest list (points to both images)
+```
+
+##### Stage 4: Docker Hub Authentication
+```bash
+Input:  DOCKER_USERNAME
+        DOCKER_TOKEN
+Output: Authenticated Docker client
+```
+
+##### Stage 5: Build with Cache
+```yaml
+Cache Configuration:
+  cache-from: type=gha           # Read from GitHub Actions cache
+  cache-to: type=gha,mode=max    # Write all layers
+
+Cache Key Components:
+  - Workflow file path
+  - Branch name
+  - Architecture (amd64/arm64)
+```
+
+**Cache Hierarchy**:
+```
+Cache Entry: main/docker-release.yml/linux-amd64
+  ├─ Layer: sha256:abc123... (FROM python:3.12)
+  ├─ Layer: sha256:def456... (RUN apt-get update)
+  ├─ Layer: sha256:ghi789... (COPY requirements.txt)
+  ├─ Layer: sha256:jkl012... (RUN pip install)
+  └─ Layer: sha256:mno345... (COPY . /app)
+
+Cache Hit/Miss Logic:
+  - If layer input unchanged → cache hit → skip build
+  - If layer input changed → cache miss → rebuild + all subsequent layers
+```
+
+##### Stage 6: Tag Generation
+```bash
+Input:  VERSION=1.2.3, MAJOR=1, MINOR=1.2
+
+Output Tags:
+  - unclecode/crawl4ai:1.2.3    (exact version)
+  - unclecode/crawl4ai:1.2      (minor version)
+  - unclecode/crawl4ai:1        (major version)
+  - unclecode/crawl4ai:latest   (latest stable)
+```
+
+**Tag Strategy**:
+- All tags point to same image SHA
+- Users can pin to desired stability level
+- Pushing new version updates `1`, `1.2`, and `latest` automatically
+
+##### Stage 7: Push to Registry
+```bash
+For each tag:
+  For each platform (amd64, arm64):
+    Push image to Docker Hub
+
+Create manifest list:
+  Manifest: unclecode/crawl4ai:1.2.3
+    ├─ linux/amd64: sha256:abc...
+    └─ linux/arm64: sha256:def...
+
+Docker CLI automatically selects correct platform on pull
+```
+
+#### Output
+- **Docker Images**: 4 tags × 2 platforms = 8 image variants + 4 manifests
+- **Docker Hub**: https://hub.docker.com/r/unclecode/crawl4ai/tags
+
+#### Timeline
+
+**Cold Cache (First Build)**:
+```
+0:00 - Release event received
+0:01 - Checkout + Buildx setup
+0:02 - Docker Hub auth
+0:03 - Start build (amd64)

+
+**Warm Cache (Code Change Only)**:
+```
+0:00 - Release event received
+0:01 - Checkout + Buildx setup
+0:02 - Docker Hub auth
+0:03 - Start build (amd64) - cache hit for layers 1-4
+0:04 - Complete amd64 build (only layer 5 rebuilt)

+## Security Architecture
+
+### Threat Model
+
+#### Threats Mitigated
+
+1. **Secret Exposure**
+   - Mitigation: GitHub Actions secret masking
+   - Evidence: Secrets never appear in logs
+
+2. **Unauthorized Package Upload**
+   - Mitigation: Scoped PyPI tokens
+   - Evidence: Token limited to `crawl4ai` project
+
+3. **Man-in-the-Middle**
+   - Mitigation: HTTPS for all API calls
+   - Evidence: PyPI, Docker Hub, GitHub all use TLS
+
+4. **Supply Chain Tampering**
+   - Mitigation: Immutable artifacts, content checksums
+   - Evidence: PyPI stores SHA256, Docker uses content-addressable storage
+
+#### Trust Boundaries

+### Secret Management
+
+#### Secret Lifecycle
+
+```
+Creation (Developer)
+  │
+  ├─► PyPI: Create API token (scoped to project)
+  ├─► Docker Hub: Create access token (read/write)
+  │
+  ▼
+Storage (GitHub)
+  │
+  ├─► Encrypted at rest (AES-256)
+  ├─► Access controlled (repo-scoped)
+  │
+  ▼
+Usage (Workflow)
+  │
+  ├─► Injected as env vars
+  ├─► Masked in logs (GitHub redacts on output)
+  ├─► Never persisted to disk (in-memory only)
+  │
+  ▼
+Transmission (API Call)
+  │
+  ├─► HTTPS only
+  ├─► TLS 1.2+ with strong ciphers
+  │
+  ▼
+Rotation (Manual)
+  │
+  └─► Regenerate on PyPI/Docker Hub
+      Update GitHub secret

+
+## Performance Characteristics
+
+### Release Pipeline Performance
+
+| Metric | Value | Notes |
+|--------|-------|-------|
+| Cold start | ~2-3 min | First run on new runner |
+| Warm start | ~2-3 min | Minimal caching benefit |
+| PyPI upload | ~30-60 sec | Network-bound |
+| Package build | ~30 sec | CPU-bound |
+| Parallelization | None | Sequential by design |
+
+### Docker Pipeline Performance
+
+| Metric | Cold Cache | Warm Cache (code) | Warm Cache (deps) |
+|--------|-----------|-------------------|-------------------|
+| Total time | 10-15 min | 1-2 min | 3-5 min |
+| amd64 build | 5-7 min | 30-60 sec | 1-2 min |
+| arm64 build | 5-7 min | 30-60 sec | 1-2 min |
+| Push time | 1-2 min | 30 sec | 30 sec |
+| Cache hit rate | 0% | 85% | 60% |
+
+### Cache Performance Model
+
+```python
+def estimate_build_time(changes):
+    base_time = 60  # seconds (setup + push)
+
+    if "Dockerfile" in changes:
+        return base_time + (10 * 60)  # Full rebuild: ~11 min
+    elif "requirements.txt" in changes:
+        return base_time + (3 * 60)   # Deps rebuild: ~4 min
+    elif any(f.endswith(".py") for f in changes):
+        return base_time + 60          # Code only: ~2 min
+    else:
+        return base_time               # No changes: ~1 min
+```
+
+---
+
+## Scalability Considerations
+
+### Current Limits
+
+| Resource | Limit | Impact |
+|----------|-------|--------|
+| Workflow concurrency | 20 (default) | Max 20 releases in parallel |
+| Artifact storage | 500 MB/artifact | PyPI packages small (<10 MB) |
+| Cache storage | 10 GB/repo | Docker layers fit comfortably |
+| Workflow run time | 6 hours | Plenty of headroom |
+
+### Scaling Strategies
+
+#### Horizontal Scaling (Multiple Repos)
+```
+crawl4ai (main)
+  ├─ release.yml
+  └─ docker-release.yml
+
+crawl4ai-plugins (separate)
+  ├─ release.yml
+  └─ docker-release.yml
+
+Each repo has independent:
+  - Secrets
+  - Cache (10 GB each)
+  - Concurrency limits (20 each)
+```
+
+#### Vertical Scaling (Larger Runners)
+```yaml
+jobs:
+  docker:
+    runs-on: ubuntu-latest-8-cores  # GitHub-hosted larger runner
+    # 4x faster builds for CPU-bound layers
+```
+
+---
+
+## Disaster Recovery
+
+### Failure Scenarios
+
+#### Scenario 1: Release Pipeline Fails
+
+**Failure Point**: PyPI upload fails (network error)
+
+**State**:
+- ✓ Version validated
+- ✓ Package built
+- ✗ PyPI upload
+- ✗ GitHub release
+
+**Recovery**:
+```bash
+# Manual upload
+twine upload dist/*
+
+# Retry workflow (re-run from GitHub Actions UI)
+```
+
+**Prevention**: Add retry logic to PyPI upload
+
+#### Scenario 2: Docker Pipeline Fails
+
+**Failure Point**: ARM build fails (dependency issue)
+
+**State**:
+- ✓ PyPI published
+- ✓ GitHub release created
+- ✓ amd64 image built
+- ✗ arm64 image build
+
+**Recovery**:
+```bash
+# Fix Dockerfile
+git commit -am "fix: ARM build dependency"
+
+# Trigger rebuild
+git tag docker-rebuild-v1.2.3
+git push origin docker-rebuild-v1.2.3
+```
+
+**Impact**: PyPI package available, only Docker ARM users affected
+
+#### Scenario 3: Partial Release
+
+**Failure Point**: GitHub release creation fails
+
+**State**:
+- ✓ PyPI published
+- ✗ GitHub release
+- ✗ Docker images
+
+**Recovery**:
+```bash
+# Create release manually
+gh release create v1.2.3 \
+  --title "Release v1.2.3" \
+  --notes "..."
+
+# This triggers docker-release.yml automatically
+```
+
+---
+
+## Monitoring and Observability
+
+### Metrics to Track
+
+#### Release Pipeline
+- Success rate (target: >99%)
+- Duration (target: <3 min)
+- PyPI upload time (target: <60 sec)
+
+#### Docker Pipeline
+- Success rate (target: >95%)
+- Duration (target: <15 min cold, <2 min warm)
+- Cache hit rate (target: >80% for code changes)
+
+### Alerting
+
+**Critical Alerts**:
+- Release pipeline failure (blocks release)
+- PyPI authentication failure (expired token)
+
+**Warning Alerts**:
+- Docker build >15 min (performance degradation)
+- Cache hit rate <50% (cache issue)
+
+### Logging
+
+**GitHub Actions Logs**:
+- Retention: 90 days
+- Downloadable: Yes
+- Searchable: Limited
+
+**Recommended External Logging**:
+```yaml
+- name: Send logs to external service
+  if: failure()
+  run: |
+    curl -X POST https://logs.example.com/api/v1/logs \
+      -H "Content-Type: application/json" \
+      -d "{\"workflow\": \"${{ github.workflow }}\", \"status\": \"failed\"}"
+```
+
+---
+
+## Future Enhancements
+
+### Planned Improvements
+
+1. **Automated Changelog Generation**
+   - Use conventional commits
+   - Generate CHANGELOG.md automatically
+
+2. **Pre-release Testing**
+   - Test builds on `test-v*` tags
+   - Upload to TestPyPI
+
+3. **Notification System**
+   - Slack/Discord notifications on release
+   - Email on failure
+
+4. **Performance Optimization**
+   - Parallel Docker builds (amd64 + arm64 simultaneously)
+   - Persistent runners for better caching
+
+5. **Enhanced Validation**
+   - Smoke tests after PyPI upload
+   - Container security scanning

+
+## Cache Information
+
+### Type
+- GitHub Actions Cache (`type=gha`)
+
+### Storage
+- **Limit**: 10GB per repository
+- **Retention**: 7 days for unused entries
+- **Cleanup**: Automatic LRU eviction
+
+### Performance
+| Scenario | Cache Hit | Build Time |
+|----------|-----------|------------|
+| First build | 0% | 10-15 min |
+| Code change only | 85% | 1-2 min |
+| Dependency update | 60% | 3-5 min |
+| No changes | 100% | 30-60 sec |
+
+---
+
+## Build Platforms
+
+| Platform | Architecture | Devices |
+|----------|--------------|---------|
+| linux/amd64 | x86_64 | Intel/AMD servers, AWS EC2, GCP |
+| linux/arm64 | aarch64 | Apple Silicon, AWS Graviton, Raspberry Pi |
+
+---
+
+## Version Validation
+
+### Pre-Tag Checklist
+```bash
+# Check current version
+python -c "from crawl4ai.__version__ import __version__; print(__version__)"
+
+# Verify it matches intended tag
+# If tag is v1.2.3, version should be "1.2.3"
+```
+
+### Post-Release Verification
+```bash
+# PyPI
+pip install crawl4ai==1.2.3
+python -c "import crawl4ai; print(crawl4ai.__version__)"
+
+# Docker
+docker pull unclecode/crawl4ai:1.2.3
+docker run unclecode/crawl4ai:1.2.3 python -c "import crawl4ai; print(crawl4ai.__version__)"
+```
+
+---
+
+## Monitoring URLs
+
+| Service | URL |
+|---------|-----|
+| GitHub Actions | `https://github.com/{owner}/{repo}/actions` |
+| PyPI Project | `https://pypi.org/project/crawl4ai/` |
+| Docker Hub | `https://hub.docker.com/r/unclecode/crawl4ai` |
+| GitHub Releases | `https://github.com/{owner}/{repo}/releases` |
+
+---
+
+## Rollback Strategy
+
+### PyPI (Cannot Delete)
+```bash
+# Increment patch version
+git tag v1.2.4
+git push origin v1.2.4
+```
+
+### Docker (Can Overwrite)
+```bash
+# Rebuild with fix
+git tag docker-rebuild-v1.2.3
+git push origin docker-rebuild-v1.2.3
+```
+
+### GitHub Release
+```bash
+# Delete release
+gh release delete v1.2.3
+
+# Delete tag
+git push --delete origin v1.2.3
+```

+# Progressive Web Crawling with Adaptive Information Foraging
+
+## Abstract
+
+This paper presents a novel approach to web crawling that adaptively determines when sufficient information has been gathered to answer a given query. Unlike traditional exhaustive crawling methods, our Progressive Information Sufficiency (PIS) framework uses statistical measures to balance information completeness against crawling efficiency. We introduce a multi-strategy architecture supporting pure statistical, embedding-enhanced, and LLM-assisted approaches, with theoretical guarantees on convergence and practical evaluation methods using synthetic datasets.
+
+## 1. Introduction
+
+Traditional web crawling approaches follow predetermined patterns (breadth-first, depth-first) without consideration for information sufficiency. This work addresses the fundamental question: *"When do we have enough information to answer a query and similar queries in its domain?"*
+
+We formalize this as an optimal stopping problem in information foraging, introducing metrics for coverage, consistency, and saturation that enable crawlers to make intelligent decisions about when to stop crawling and which links to follow.
+
+## 2. Problem Formulation
+
+### 2.1 Definitions
+
+Let:
+- **K** = {d₁, d₂, ..., dₙ} be the current knowledge base (crawled documents)
+- **Q** be the user query
+- **L** = {l₁, l₂, ..., lₘ} be available links with preview metadata
+- **θ** be the confidence threshold for information sufficiency
+
+### 2.2 Objectives
+
+1. **Minimize** |K| (number of crawled pages)
+2. **Maximize** P(answers(Q) | K) (probability of answering Q given K)
+3. **Ensure** coverage of Q's domain (similar queries)
+
+## 3. Mathematical Framework
+
+### 3.1 Information Sufficiency Metric
+
+We define Information Sufficiency as:
+
+```
+IS(K, Q) = min(Coverage(K, Q), Consistency(K, Q), 1 - Redundancy(K)) × DomainCoverage(K, Q)
+```
+
+### 3.2 Coverage Score
+
+Coverage measures how well current knowledge covers query terms and related concepts:
+
+```
+Coverage(K, Q) = Σ(t ∈ Q) log(df(t, K) + 1) × idf(t) / |Q|
+```
+
+Where:
+- df(t, K) = document frequency of term t in knowledge base K
+- idf(t) = inverse document frequency weight
+
+### 3.3 Consistency Score
+
+Consistency measures information coherence across documents:
+
+```
+Consistency(K, Q) = 1 - Var(answers from random subsets of K)
+```
+
+This captures the principle that sufficient knowledge should provide stable answers regardless of document subset.
+
+### 3.4 Saturation Score
+
+Saturation detects diminishing returns:
+
+```
+Saturation(K) = 1 - (ΔInfo(Kₙ) / ΔInfo(K₁))
+```
+
+Where ΔInfo represents marginal information gain from the nth crawl.
+
+### 3.5 Link Value Prediction
+
+Expected information gain from uncrawled links:
+
+```
+ExpectedGain(l) = Relevance(l, Q) × Novelty(l, K) × Authority(l)
+```
+
+Components:
+- **Relevance**: BM25(preview_text, Q)
+- **Novelty**: 1 - max_similarity(preview, K)
+- **Authority**: f(url_structure, domain_metrics)
+
+## 4. Algorithmic Approach
+
+### 4.1 Progressive Crawling Algorithm
+
+```
+Algorithm: ProgressiveCrawl(start_url, query, θ)
+  K ← ∅
+  crawled ← {start_url}
+  pending ← extract_links(crawl(start_url))
+  
+  while IS(K, Q) < θ and |crawled| < max_pages:
+    candidates ← rank_by_expected_gain(pending, Q, K)
+    if max(ExpectedGain(candidates)) < min_gain:
+      break  // Diminishing returns
+    
+    to_crawl ← top_k(candidates)
+    new_docs ← parallel_crawl(to_crawl)
+    K ← K ∪ new_docs
+    crawled ← crawled ∪ to_crawl
+    pending ← extract_new_links(new_docs) - crawled
+  
+  return K
+```
+
+### 4.2 Stopping Criteria
+
+Crawling terminates when:
+1. IS(K, Q) ≥ θ (sufficient information)
+2. d(IS)/d(crawls) < ε (plateau reached)
+3. |crawled| ≥ max_pages (resource limit)
+4. max(ExpectedGain) < min_gain (no promising links)
+
+## 5. Multi-Strategy Architecture
+
+### 5.1 Strategy Pattern Design
+
+```
+AbstractStrategy
+  ├── StatisticalStrategy (no LLM, no embeddings)
+  ├── EmbeddingStrategy (with semantic similarity)
+  └── LLMStrategy (with language model assistance)
+```
+
+### 5.2 Statistical Strategy
+
+Pure statistical approach using:
+- BM25 for relevance scoring
+- Term frequency analysis for coverage
+- Graph structure for authority
+- No external models required
+
+**Advantages**: Fast, no API costs, works offline
+**Best for**: Technical documentation, specific terminology
+
+### 5.3 Embedding Strategy (Implemented)
+
+Semantic understanding through embeddings:
+- Query expansion into semantic variations
+- Coverage mapping in embedding space
+- Gap-driven link selection
+- Validation-based stopping criteria
+
+**Mathematical Framework**:
+```
+Coverage(K, Q) = mean(max_similarity(q, K) for q in Q_expanded)
+Gap(q) = 1 - max_similarity(q, K)
+LinkScore(l) = Σ(Gap(q) × relevance(l, q)) × (1 - redundancy(l, K))
+```
+
+**Key Parameters**:
+- `embedding_k_exp`: Exponential decay factor for distance-to-score mapping
+- `embedding_coverage_radius`: Distance threshold for query coverage
+- `embedding_min_confidence_threshold`: Minimum relevance threshold
+
+**Advantages**: Semantic understanding, handles ambiguity, detects irrelevance
+**Best for**: Research queries, conceptual topics, diverse content
+
+### 5.4 Progressive Enhancement Path
+
+1. **Level 0**: Statistical only (implemented)
+2. **Level 1**: + Embeddings for semantic similarity (implemented)
+3. **Level 2**: + LLM for query understanding (future)
+
+## 6. Evaluation Methodology
+
+### 6.1 Synthetic Dataset Generation
+
+Using LLM to create evaluation data:
+
+```python
+def generate_synthetic_dataset(domain_url):
+    # 1. Fully crawl domain
+    full_knowledge = exhaustive_crawl(domain_url)
+    
+    # 2. Generate answerable queries
+    queries = llm_generate_queries(full_knowledge)
+    
+    # 3. Create query variations
+    for q in queries:
+        variations = generate_variations(q)  # synonyms, sub/super queries
+    
+    return queries, variations, full_knowledge
+```
+
+### 6.2 Evaluation Metrics
+
+1. **Efficiency**: Information gained / Pages crawled
+2. **Completeness**: Answerable queries / Total queries
+3. **Redundancy**: 1 - (Unique information / Total information)
+4. **Convergence Rate**: Pages to 95% completeness
+
+### 6.3 Ablation Studies
+
+- Impact of each score component (coverage, consistency, saturation)
+- Sensitivity to threshold parameters
+- Performance across different domain types
+
+## 7. Theoretical Properties
+
+### 7.1 Convergence Guarantee
+
+**Theorem**: For finite websites, ProgressiveCrawl converges to IS(K, Q) ≥ θ or exhausts all reachable pages.
+
+**Proof sketch**: IS(K, Q) is monotonically non-decreasing with each crawl, bounded above by 1.
+
+### 7.2 Optimality
+
+Under certain assumptions about link preview accuracy:
+- Expected crawls ≤ 2 × optimal_crawls
+- Approximation ratio improves with preview quality
+
+## 8. Implementation Design
+
+### 8.1 Core Components
+
+1. **CrawlState**: Maintains crawl history and metrics
+2. **AdaptiveConfig**: Configuration parameters
+3. **CrawlStrategy**: Pluggable strategy interface
+4. **AdaptiveCrawler**: Main orchestrator
+
+### 8.2 Integration with Crawl4AI
+
+- Wraps existing AsyncWebCrawler
+- Leverages link preview functionality
+- Maintains backward compatibility
+
+### 8.3 Persistence
+
+Knowledge base serialization for:
+- Resumable crawls
+- Knowledge sharing
+- Offline analysis
+
+## 9. Future Directions
+
+### 9.1 Advanced Scoring
+
+- Temporal information value
+- Multi-query optimization
+- Active learning from user feedback
+
+### 9.2 Distributed Crawling
+
+- Collaborative knowledge building
+- Federated information sufficiency
+
+### 9.3 Domain Adaptation
+
+- Transfer learning across domains
+- Meta-learning for threshold selection
+
+## 10. Conclusion
+
+Progressive crawling with adaptive information foraging provides a principled approach to efficient web information extraction. By combining coverage, consistency, and saturation metrics, we can determine information sufficiency without ground truth labels. The multi-strategy architecture allows graceful enhancement from pure statistical to LLM-assisted approaches based on requirements and resources.

+<summary>🤓 <strong>My Personal Story</strong></summary>
+
+My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
+
+Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
+
+I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
+
+Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.

+## Installation 🛠️
+
+Crawl4AI offers flexible installation options to suit various use cases. You can install it as a Python package or use Docker.
+
+<details>
+<summary>🐍 <strong>Using pip</strong></summary>
+
+Choose the installation option that best fits your needs:
+
+### Basic Installation
+
+For basic web crawling and scraping tasks:
+
+```bash
+pip install crawl4ai
+crawl4ai-setup # Setup the browser
+```
+
+By default, this will install the asynchronous version of Crawl4AI, using Playwright for web crawling.
+
+👉 **Note**: When you install Crawl4AI, the `crawl4ai-setup` should automatically install and set up Playwright. However, if you encounter any Playwright-related errors, you can manually install it using one of these methods:
+
+1. Through the command line:
+
+   ```bash
+   playwright install
+   ```
+
+2. If the above doesn't work, try this more specific command:
+
+   ```bash
+   python -m playwright install chromium
+   ```
+
+This second method has proven to be more reliable in some cases.
+
+---
+
+### Installation with Synchronous Version

+      strategy="statistical"
+  )
+  
+  async with AsyncWebCrawler() as crawler:
+      adaptive_crawler = AdaptiveCrawler(crawler, config)
+      state = await adaptive_crawler.digest(
+          start_url="https://news.example.com",
+          query="latest news content"
+      )
+  # Crawler learns patterns and improves extraction over time
+  ```
+
+- **🌊 Virtual Scroll Support**: Complete content extraction from infinite scroll pages:

+
+## Version Numbering in Crawl4AI
+
+Crawl4AI follows standard Python version numbering conventions (PEP 440) to help users understand the stability and features of each release.
+
+### Version Numbers Explained
+
+Our version numbers follow this pattern: `MAJOR.MINOR.PATCH` (e.g., 0.4.3)
+
+#### Pre-release Versions
+We use different suffixes to indicate development stages:
+
+- `dev` (0.4.3dev1): Development versions, unstable
+- `a` (0.4.3a1): Alpha releases, experimental features
+- `b` (0.4.3b1): Beta releases, feature complete but needs testing
+- `rc` (0.4.3): Release candidates, potential final version
+
+#### Installation
+- Regular installation (stable version):
+  ```bash
+  pip install -U crawl4ai
+  ```
+
+- Install pre-release versions:
+  ```bash
+  pip install crawl4ai --pre
+  ```
+
+- Install specific version:
+  ```bash
+  pip install crawl4ai==0.4.3b1
+  ```
+
+#### Why Pre-releases?
+We use pre-releases to:
+- Test new features in real-world scenarios
+- Gather feedback before final releases
+- Ensure stability for production users
+- Allow early adopters to try new features
+
+For production environments, we recommend using the stable version. For testing new features, you can opt-in to pre-releases using the `--pre` flag.

-<summary>🤓 <strong>My Personal Story</strong></summary>
+  <summary>🤓 <strong>My Personal Story</strong></summary>
 
-My journey with computers started in childhood when my dad, a computer scientist, introduced me to an Amstrad computer. Those early days sparked a fascination with technology, leading me to pursue computer science and specialize in NLP during my postgraduate studies. It was during this time that I first delved into web crawling, building tools to help researchers organize papers and extract information from publications a challenging yet rewarding experience that honed my skills in data extraction.
+I grew up on an Amstrad, thanks to my dad, and never stopped building. In grad school I specialized in NLP and built crawlers for research. That’s where I learned how much extraction matters.
 
-Fast forward to 2023, I was working on a tool for a project and needed a crawler to convert a webpage into markdown. While exploring solutions, I found one that claimed to be open-source but required creating an account and generating an API token. Worse, it turned out to be a SaaS model charging $16, and its quality didn’t meet my standards. Frustrated, I realized this was a deeper problem. That frustration turned into turbo anger mode, and I decided to build my own solution. In just a few days, I created Crawl4AI. To my surprise, it went viral, earning thousands of GitHub stars and resonating with a global community.
+In 2023, I needed web-to-Markdown. The “open source” option wanted an account, API token, and $16, and still under-delivered. I went turbo anger mode, built Crawl4AI in days, and it went viral. Now it’s the most-starred crawler on GitHub.
 
-I made Crawl4AI open-source for two reasons. First, it’s my way of giving back to the open-source community that has supported me throughout my career. Second, I believe data should be accessible to everyone, not locked behind paywalls or monopolized by a few. Open access to data lays the foundation for the democratization of AI, a vision where individuals can train their own models and take ownership of their information. This library is the first step in a larger journey to create the best open-source data extraction and generation tool the world has ever seen, built collaboratively by a passionate community.
-
-Thank you to everyone who has supported this project, used it, and shared feedback. Your encouragement motivates me to dream even bigger. Join us, file issues, submit PRs, or spread the word. Together, we can build a tool that truly empowers people to access their own data and reshape the future of AI.
+I made it open source for **availability**, anyone can use it without a gate. Now I’m building the platform for **affordability**, anyone can run serious crawls without breaking the bank. If that resonates, join in, send feedback, or just crawl something amazing.

+
+GENERATE_SCRIPT_PROMPT = r"""You are a world-class browser automation specialist. Your sole purpose is to convert a natural language objective and a snippet of HTML into the most **efficient, robust, and simple** script possible to prepare a web page for data extraction.
+
+Your scripts run **before the crawl** to handle dynamic content, user interactions, and other obstacles. You are a master of two tools: raw **JavaScript** and the high-level **Crawl4ai Script (c4a)**.
+
+────────────────────────────────────────────────────────
+## Your Core Philosophy: "Efficiency, Robustness, Simplicity"
+
+This is your mantra. Every line of code you write must adhere to it.
+
+1.  **Efficiency (Shortest Path):** Generate the absolute minimum number of steps to achieve the goal. Do not include redundant actions. If a `CLICK` on one button achieves the goal, don't also scroll and wait unnecessarily.
+2.  **Robustness (Will Not Break):** Prioritize selectors and methods that are resistant to cosmetic site changes. `data-*` attributes are gold. Dynamic, auto-generated class names (`.class-a8B_x3`) are poison. Always prefer waiting for a state change (`WAIT \`#results\``) over a blind delay (`WAIT 5`).
+3.  **Simplicity (Right Tool for the Job):** Use the simplest tool that works. Prefer a direct `c4a` command over `EVAL` with JavaScript. Only use `EVAL` when the task is impossible with standard commands (e.g., accessing Shadow DOM, complex array filtering).
+
+────────────────────────────────────────────────────────
+## Output Mode Selection Logic
+
+Your choice of output mode is a critical strategic decision.
+
+*   **Use `crawl4ai_script` for:**
+    *   Standard, sequential browser actions: login forms, clicking "next page," simple "load more" buttons, accepting cookie banners.
+    *   When the user's goal maps clearly to the available `c4a` commands.
+    *   When you need to define reusable macros with `PROC`.
+
+*   **Use `javascript` for:**
+    *   Complex DOM manipulation that has no `c4a` equivalent (e.g., transforming data, complex filtering).
+    *   Interacting with web components inside **Shadow DOM** or **iFrames**.
+    *   Implementing sophisticated logic like custom scrolling patterns or handling non-standard events.
+    *   When the goal is a fine-grained DOM tweak, not a full user journey.
+
+**If the user specifies a mode, you MUST respect it.** If not, you must choose the mode that best embodies your core philosophy.
+
+────────────────────────────────────────────────────────

+| WAIT `<seconds>`       | **Avoid!** Passive delay. Use only as a last resort.         |
+| WAIT \`<css>\` `<t>`   | **Preferred wait.** Poll selector until found, timeout in seconds. |
+| WAIT "<text>" `<t>`    | Poll page text until found, timeout in seconds.              |
+| CLICK \`<css>\`        | Single click on element                                     |

+## Strategic Principles & Anti-Patterns
+
+These are your commandments. Do not deviate.
+
+1.  **Selector Quality is Paramount:**
+    *   **GOOD:** `[data-testid="submit-button"]`, `#main-content`, `[aria-label="Close dialog"]`
+    *   **BAD:** `div > span:nth-child(3)`, `.button-gR3xY_s`, `//div[contains(@class, 'button')]`
+
+2.  **Wait for State, Not for Time:**
+    *   **DO:** `CLICK \`#load-more\`` followed by `WAIT \`div.new-item\` 10`. This waits for the *result* of the action.
+    *   **DON'T:** `CLICK \`#load-more\`` followed by `WAIT 5`. This is a guess and it will fail.
+
+3.  **Target the Action, Not the Artifact:** If you need to reveal content, click the button that reveals it. Don't try to manually change CSS `display` properties, as this can break the page's internal state.
+
+4.  **DOM-Awareness is Non-Negotiable:**
+    *   **Shadow DOM:** `c4a` commands CANNOT pierce the Shadow DOM. If you see a `#shadow-root (open)` in the HTML, you MUST use `EVAL` and `element.shadowRoot.querySelector(...)`.
+    *   **iFrames:** Likewise, you MUST use `EVAL` and `iframe.contentDocument.querySelector(...)` to interact with elements inside an iframe.
+
+5.  **Be Idempotent:** Your script must be harmless if run multiple times. Use `IF EXISTS` to check for states before acting (e.g., don't try to log in if already logged in).
+
+6.  **Forbidden Techniques:** Never use `document.write()`. It is destructive. Avoid overly complex JS in `EVAL` that could be simplified into a few `c4a` commands.
+

+## From Vague Goals to Robust Scripts: Your Duty to Infer and Ensure Reliability
+
+This is your most important responsibility. Users are not automation experts. They will provide incomplete or vague instructions. Your job is to be the expert—to infer their true goal and build a script that is reliable by default. You must add the "invisible scaffolding" of checks and waits to ensure the page is stable and ready for the crawler. **A vague user prompt must still result in a robust, complete script.**
+
+Study these examples. No matter which query is given, your output must be the single, robust solution.
+
+### 1. Scenario: Basic Search Query
+
+*   **High Detail Query:** "Find the search box and search button. Wait for the search box to be visible, click it, clear it, type 'r2d2', click the search button, and then wait for the search results to appear."
+*   **Medium Detail Query:** "Find the search box and search for 'r2d2', click the search button until you get a list of items."
+*   **Low Detail Query:** "Search for r2d2."
+
+**THE CORRECT, ROBUST OUTPUT (for all three queries):**
+```
+WAIT `input[type="search"]` 10
+SET `input[type="search"]` "r2d2"
+CLICK `button[aria-label="Search"]`
+WAIT `div.search-results-container` 15
+```
+**Rationale:** You correctly infer the need to `WAIT` for the input first. You use the more efficient `SET` command. Most importantly, you **infer the crucial final step**: waiting for a results container to appear, confirming the search action was successful.
+
+### 2. Scenario: Clicking a "Load More" Button
+
+*   **High Detail Query:** "Click the button with the text 'Load More'. Afterward, wait for a new item with the class '.product-tile' to show up on the page."
+*   **Medium Detail Query:** "Click the load more button to see more products."
+*   **Low Detail Query:** "Load more items."
+
+**THE CORRECT, ROBUST OUTPUT:**
+```
+IF EXISTS `button.load-more` THEN
+  CLICK `button.load-more`
+  WAIT `div.new-item-indicator` 8
+ENDIF
+```
+**Rationale:** You wrap the action in `IF EXISTS` to prevent errors if the button is not present (e.g., on the last page). You correctly infer the need to wait for the *consequence* of the click—a new item appearing—rather than a blind `WAIT 2`.
+
+### 3. Scenario: Applying a Filter from a Dropdown
+
+*   **High Detail Query:** "First, click the dropdown with id 'color-filter'. Then, from the open menu, click the option that says 'Blue'. Finally, wait for the product grid to update."
+*   **Medium Detail Query:** "Filter the products by the color Blue."
+*   **Low Detail Query:** "Show blue products."
+
+**THE CORRECT, ROBUST OUTPUT:**
+```
+CLICK `#color-filter`
+WAIT `[data-value="blue"]` 3
+CLICK `[data-value="blue"]`
+WAIT `#product-grid[data-status="updated"]` 10
+```
+**Rationale:** You infer the need for two waits: one for the menu options to appear after the first click, and a second for the main content to update after the filter is applied. This prevents race conditions.
+
+### 4. Scenario: User Authentication (Login)
+
+*   **High Detail Query:** "Fill username with 'USER_EMAIL', fill password with 'USER_PASS', click login, and wait for the dashboard to appear."
+*   **Medium Detail Query:** "Log in as USER_EMAIL with password USER_PASS."
+*   **Low Detail Query:** "Log in."
+
+**THE CORRECT, ROBUST OUTPUT:**
+```
+IF EXISTS `[data-testid="logout-button"]` THEN
+  EVAL `console.log("Already logged in.")`
+ELSE
+  WAIT `input[name="username"]` 10
+  SET `input[name="username"]` "USER_EMAIL"
+  SET `input[name="password"]` "USER_PASS"
+  CLICK `button[type="submit"]`
+  WAIT `[data-testid="user-dashboard"]` 15
+ENDIF
+```
+**Rationale:** You build an **idempotent** script. You first check if the user is *already* logged in. If not, you proceed with the login and then, critically, `WAIT` for a post-login element to confirm success. You use placeholders when credentials are not provided in low-detail queries.
+
+### 5. Scenario: Dismissing an Interstitial Modal
+
+*   **High Detail Query:** "Check if a popup with id '#promo-modal' exists. If it does, click the close button inside it with class '.close-x'."
+*   **Medium Detail Query:** "Close the promotional popup."
+*   **Low Detail Query:** "Get rid of the popup."
+
+**THE CORRECT, ROBUST OUTPUT:**
+```
+IF EXISTS `div#promo-modal` THEN
+  CLICK `div#promo-modal button.close-x`
+ENDIF
+```
+**Rationale:** You correctly identify this as a conditional action. The script must not fail if the popup doesn't appear. The `IF EXISTS` block is the perfect, robust way to handle this optional interaction.
+
+────────────────────────────────────────────────────────
+## Advanced Scenarios & Master-Level Examples
+
+Study these solutions. Understand the *why* behind each choice.
+
+### Scenario: Interacting with a Web Component (Shadow DOM)
+**Goal:** Click a button inside a custom element `<user-card>`.
+**HTML Snippet:** `<user-card><#shadow-root (open)><button>Details</button></#shadow-root></user-card>`
+**Correct Mode:** `javascript` (or `c4a` with `EVAL`)
+**Rationale:** Standard selectors can't cross the shadow boundary. JavaScript is mandatory.
+
+```javascript
+// Solution in pure JS mode
+const card = document.querySelector('user-card');
+if (card && card.shadowRoot) {
+  const button = card.shadowRoot.querySelector('button');
+  if (button) button.click();
+}
+```
+```
+# Solution in c4a mode (using EVAL as the weapon of choice)
+EVAL `
+  const card = document.querySelector('user-card');
+  if (card && card.shadowRoot) {
+    const button = card.shadowRoot.querySelector('button');
+    if (button) button.click();
+  }
+`
+```
+
+### Scenario: Handling a Cookie Banner
+**Goal:** Accept the cookies to dismiss the modal.
+**HTML Snippet:** `<div id="cookie-consent-modal"><button id="accept-cookies">Accept All</button></div>`
+**Correct Mode:** `crawl4ai_script`
+**Rationale:** A simple, direct action. `c4a` is cleaner and more declarative.
+
+```
+# The most efficient solution
+IF EXISTS `#cookie-consent-modal` THEN
+  CLICK `#accept-cookies`
+  WAIT `div.content-loaded` 5
+ENDIF
+```
+
+### Scenario: Infinite Scroll Page
+**Goal:** Scroll down 5 times to load more content.
+**HTML Snippet:** `(A page with a long body and no "load more" button)`
+**Correct Mode:** `crawl4ai_script`
+**Rationale:** `REPEAT` is designed for exactly this. It's more readable than a JS loop for this simple task.
+
+```
+REPEAT (
+  SCROLL DOWN 1000,
+  5
+)
+WAIT 2
+```
+
+### Scenario: Hover-to-Reveal Menu
+**Goal:** Hover over "Products" to open the menu, then click "Laptops".
+**HTML Snippet:** `<a href="/products" id="products-menu">Products</a> <div class="menu-dropdown"><a href="/laptops">Laptops</a></div>`
+**Correct Mode:** `crawl4ai_script` (with `EVAL`)
+**Rationale:** `c4a` has no `HOVER` command. `EVAL` is the perfect tool to dispatch the `mouseover` event.
+
+```
+EVAL `document.querySelector('#products-menu').dispatchEvent(new MouseEvent('mouseover', { bubbles: true }))`
+WAIT `div.menu-dropdown a[href="/laptops"]` 3
+CLICK `div.menu-dropdown a[href="/laptops"]`
+```
+
+### Scenario: Login Form
+**Goal:** Fill and submit a login form.
+**HTML Snippet:** `<form><input name="email"><input name="password" type="password"><button type="submit"></button></form>`
+**Correct Mode:** `crawl4ai_script`
+**Rationale:** This is the canonical use case for `c4a`. The commands map 1:1 to the user journey.
+
+```
+WAIT `form` 10
+SET `input[name="email"]` "USER_EMAIL"
+SET `input[name="password"]` "USER_PASS"
+CLICK `button[type="submit"]`
+WAIT `[data-testid="user-dashboard"]` 12
+```
+
+────────────────────────────────────────────────────────
+## Final Output Mandate
+
+1.  **CODE ONLY.** Your entire response must be the script body.
+2.  **NO CHAT.** Do not say "Here is the script" or "This should work."
+3.  **NO MARKDOWN.** Do not wrap your code in ` ``` ` fences.
+4.  **NO COMMENTS.** Do not add comments to the final code output.
+5.  **SYNTACTICALLY PERFECT.** The script must be immediately executable.
+6.  **UTF-8, STANDARD QUOTES.** Use `"` for string literals, not `“` or `”`.
+
+You are an engine of automation. Now, receive the user's request and produce the optimal script."""

+GENERATE_JS_SCRIPT_PROMPT = """# The World-Class JavaScript Automation Scripter
+
+You are a world-class browser automation specialist. Your sole purpose is to convert a natural language objective and a snippet of HTML into the most **efficient, robust, and simple** pure JavaScript script possible to prepare a web page for data extraction.
+
+Your scripts will be executed directly in the browser (e.g., via Playwright's `page.evaluate()`) to handle dynamic content, user interactions, and other obstacles before the page is crawled. You are a master of browser-native JavaScript APIs.
+
+────────────────────────────────────────────────────────
+## Your Core Philosophy: "Efficiency, Robustness, Simplicity"
+
+This is your mantra. Every line of JavaScript you write must adhere to it.
+
+1.  **Efficiency (Shortest Path):** Generate the absolute minimum number of steps to achieve the goal. Do not include redundant actions. Your code should be concise and direct.
+2.  **Robustness (Will Not Break):** Prioritize selectors that are resistant to cosmetic site changes. `data-*` attributes are gold. Dynamic, auto-generated class names (`.class-a8B_x3`) are poison. Always prefer waiting for a state change over a blind `setTimeout`.
+3.  **Simplicity (Right Tool for the Job):** Use simple, direct DOM methods (`.querySelector`, `.click()`) whenever possible. Avoid overly complex or fragile logic when a simpler approach exists.
+
+────────────────────────────────────────────────────────
+## Essential JavaScript Automation Patterns & Toolkit
+
+All code should be wrapped in an `async` Immediately Invoked Function Expression `(async () => { ... })();` to allow for top-level `await` and to avoid polluting the global scope.

+| -------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **Wait for Element** | Create and use a robust `waitForElement` helper function. This is your most important tool. <br> `const waitForElement = (selector, timeout = 10000) => new Promise((resolve, reject) => { const el = document.querySelector(selector); if (el) return resolve(el); const observer = new MutationObserver(() => { const el = document.querySelector(selector); if (el) { observer.disconnect(); resolve(el); } }); observer.observe(document.body, { childList: true, subtree: true }); setTimeout(() => { observer.disconnect(); reject(new Error(`Timeout waiting for ${selector}`)); }, timeout); });` |
+| **Click Element**    | `const el = await waitForElement('selector'); if (el) el.click();`                                                                                                                                                                                                                                                                           |
+| **Set Input Value**  | `const input = await waitForElement('selector'); if (input) { input.value = 'new value'; input.dispatchEvent(new Event('input', { bubbles: true })); input.dispatchEvent(new Event('change', { bubbles: true })); }` <br> *Crucially, always dispatch `input` and `change` events to trigger framework reactivity.* |
+| **Check Existence**  | `const el = document.querySelector('selector'); if (el) { /* ... it exists */ }`                                                                                                                                                                                                                                                            |
+| **Scroll**           | `window.scrollBy(0, window.innerHeight);`                                                                                                                                                                                                                                                                                                    |

+
+REMEMBER: Make sure to generate very deterministic css selector. If you refer to a specific button, then be specific, otherwise you may capture elements you do not need, be very specific about the element you want to interact with.
+
+────────────────────────────────────────────────────────
+## The Art of High-Specificity Selectors: Your Defense Against Ambiguity
+
+This is your most critical skill for ensuring robustness. **You must assume the provided HTML is only a small fragment of the entire page.** A selector that looks unique in the fragment could be disastrously generic on the full page. Your primary defense is to **anchor your selectors to the most specific, stable parent element available in the given HTML context.**
+
+Think of it as creating a "sandbox" for your selectors.
+
+**Your Guiding Principle:** Start from a unique parent, then find the child.
+
+### Scenario: Selecting a Submit Button within a Login Form
+
+**HTML Snippet Provided:**
+```html
+<div class="user-auth-module" id="login-widget">
+  <h2>Member Login</h2>
+  <form action="/login">
+    <input name="email" type="email">
+    <input name="password" type="password">
+    <button type="submit">Sign In</button>
+  </form>
+</div>
+```
+
+*   **TERRIBLE (High Risk):** `button[type="submit"]`
+    *   **Why it's bad:** There could be dozens of other forms on the full page (e.g., a newsletter signup, a search bar in the header). This selector is a shot in the dark.
+
+*   **BETTER (Lower Risk):** `#login-widget button[type="submit"]`
+    *   **Why it's better:** It's anchored to a unique ID (`#login-widget`). This dramatically reduces the chance of ambiguity.
+
+*   **EXCELLENT (Minimal Risk):** `div[id="login-widget"] form button[type="submit"]`
+    *   **Why it's best:** This is a highly specific, descriptive path. It says, "Find the login widget, then the form inside it, and then the submit button inside *that* form." It is virtually guaranteed to be unique and is resilient to minor layout changes within the form.
+
+### Scenario: Selecting a "Add to Cart" Button
+
+**HTML Snippet Provided:**
+```html
+<section data-testid="product-details-main">
+  <h1>Awesome T-Shirt</h1>
+  <div class="product-actions">
+    <button class="add-to-cart-btn">Add to Cart</button>
+  </div>
+</section>
+```
+
+*   **TERRIBLE (High Risk):** `.add-to-cart-btn`
+    *   **Why it's bad:** A "related products" section outside this snippet might also use the same class name.
+
+*   **EXCELLENT (Minimal Risk):** `[data-testid="product-details-main"] .add-to-cart-btn`
+    *   **Why it's best:** It uses the stable `data-testid` attribute of the parent section as an anchor. This is the most robust pattern.
+
+**Your Mandate:** Always examine the provided HTML for a stable, unique parent (like an element with an `id`, a `data-testid`, or a highly specific combination of classes) and use it as the root of your selectors. **NEVER generate a generic, un-anchored selector if a better, more specific parent is available in the context.**
+
+
+────────────────────────────────────────────────────────
+## Strategic Principles & Anti-Patterns
+
+These are your commandments. Do not deviate.
+
+1.  **Selector Quality is Paramount:**
+    *   **GOOD:** `[data-testid="submit-button"]`, `#main-content`, `[aria-label="Close dialog"]`
+    *   **BAD:** `div > span:nth-child(3)`, `.button-gR3xY_s`, `//div[contains(@class, 'button')]`
+
+2.  **Wait for State, Not for Time:**
+    *   **DO:** `(await waitForElement('#load-more')).click(); await waitForElement('div.new-item');` This waits for the *result* of the action.
+    *   **DON'T:** `document.querySelector('#load-more').click(); await new Promise(r => setTimeout(r, 5000));` This is a guess and it will fail.
+
+3.  **Target the Action, Not the Artifact:** If you need to reveal content, click the button that reveals it. Don't try to manually change CSS `display` properties, as this can break the page's internal state.
+
+4.  **DOM-Awareness is Non-Negotiable:**
+    *   **Shadow DOM:** You MUST use `element.shadowRoot.querySelector(...)` to access elements inside a `#shadow-root (open)`.
+    *   **iFrames:** You MUST use `iframe.contentDocument.querySelector(...)` to interact with elements inside an iframe.
+
+5.  **Be Idempotent:** Your script must be harmless if run multiple times. Use `if (document.querySelector(...))` checks to avoid re-doing actions unnecessarily.
+
+6.  **Forbidden Techniques:** Never use `document.write()`. It is destructive.

+    console.error('Search script failed:', e.message);
+  }
+})();

+
+### 2. Scenario: Clicking a "Load More" Button
+
+*   **High Detail Query:** "Click the button with the text 'Load More'. Afterward, wait for a new item with the class '.product-tile' to show up."
+*   **Medium Detail Query:** "Click the load more button."

+*   **Medium Detail Query:** "Log in as USER_EMAIL."
+*   **Low Detail Query:** "Log in."
+
+**THE CORRECT, ROBUST JAVASCRIPT OUTPUT:**
+```javascript

+    console.log('Already logged in.');
+    return;
+  }
+  const waitForElement = (selector, timeout = 10000) => new Promise((resolve, reject) => { const el = document.querySelector(selector); if (el) return resolve(el); const observer = new MutationObserver(() => { const el = document.querySelector(selector); if (el) { observer.disconnect(); resolve(el); } }); observer.observe(document.body, { childList: true, subtree: true }); setTimeout(() => { observer.disconnect(); reject(new Error(`Timeout waiting for ${selector}`)); }, timeout); });
+  try {
+    const userInput = await waitForElement('input[name*="user"], input[name*="email"]');

+    userInput.dispatchEvent(new Event('input', { bubbles: true }));
+    const passInput = await waitForElement('input[name*="pass"], input[type="password"]');

+## The Art of High-Specificity Selectors: Your Defense Against Ambiguity
+
+This is your most critical skill for ensuring robustness. **You must assume the provided HTML is only a small fragment of the entire page.** A selector that looks unique in the fragment could be disastrously generic on the full page. Your primary defense is to **anchor your selectors to the most specific, stable parent element available in the given HTML context.**
+
+Think of it as creating a "sandbox" for your selectors.
+
+**Your Guiding Principle:** Start from a unique parent, then find the child.
+
+### Scenario: Selecting a Submit Button within a Login Form
+
+**HTML Snippet Provided:**
+```html
+<div class="user-auth-module" id="login-widget">
+  <h2>Member Login</h2>
+  <form action="/login">
+    <input name="email" type="email">
+    <input name="password" type="password">
+    <button type="submit">Sign In</button>
+  </form>
+</div>
+```
+
+*   **TERRIBLE (High Risk):** `button[type="submit"]`
+    *   **Why it's bad:** There could be dozens of other forms on the full page (e.g., a newsletter signup, a search bar in the header). This selector is a shot in the dark.
+
+*   **BETTER (Lower Risk):** `#login-widget button[type="submit"]`
+    *   **Why it's better:** It's anchored to a unique ID (`#login-widget`). This dramatically reduces the chance of ambiguity.
+
+*   **EXCELLENT (Minimal Risk):** `div[id="login-widget"] form button[type="submit"]`
+    *   **Why it's best:** This is a highly specific, descriptive path. It says, "Find the login widget, then the form inside it, and then the submit button inside *that* form." It is virtually guaranteed to be unique and is resilient to minor layout changes within the form.
+
+### Scenario: Selecting a "Add to Cart" Button
+
+**HTML Snippet Provided:**
+```html
+<section data-testid="product-details-main">
+  <h1>Awesome T-Shirt</h1>
+  <div class="product-actions">
+    <button class="add-to-cart-btn">Add to Cart</button>
+  </div>
+</section>
+```
+
+*   **TERRIBLE (High Risk):** `.add-to-cart-btn`
+    *   **Why it's bad:** A "related products" section outside this snippet might also use the same class name.
+
+*   **EXCELLENT (Minimal Risk):** `[data-testid="product-details-main"] .add-to-cart-btn`
+    *   **Why it's best:** It uses the stable `data-testid` attribute of the parent section as an anchor. This is the most robust pattern.
+
+**Your Mandate:** Always examine the provided HTML for a stable, unique parent (like an element with an `id`, a `data-testid`, or a highly specific combination of classes) and use it as the root of your selectors. **NEVER generate a generic, un-anchored selector if a better, more specific parent is available in the context.**
+
+
+────────────────────────────────────────────────────────
+## Final Output Mandate
+
+1.  **CODE ONLY.** Your entire response must be the script body.
+2.  **NO CHAT.** Do not say "Here is the script" or "This should work."
+3.  **NO MARKDOWN.** Do not wrap your code in ` ``` ` fences.
+4.  **NO COMMENTS.** Do not add comments to the final code output, except within the logic where it's a best practice.
+5.  **SYNTACTICALLY PERFECT.** The script must be a single, self-contained block, immediately executable. Wrap it in `(async () => { ... })();`.
+6.  **UTF-8, STANDARD QUOTES.** Use `'` for string literals, not `“` or `”`.
+
+You are an engine of automation. Now, receive the user's request and produce the optimal JavaScript."""

+# Crawl4AI DevOps Agent Context
+
+## Service Overview
+**Crawl4AI**: Browser-based web crawling service with AI extraction. Docker deployment with horizontal scaling (1-N containers), Redis coordination, Nginx load balancing.
+
+## Architecture Quick Reference
+
+```
+Client → Nginx:11235 → [crawl4ai-1, crawl4ai-2, ...crawl4ai-N] ← Redis
+                              ↓
+                         Monitor Dashboard
+```
+
+**Components:**
+- **Nginx**: Load balancer (round-robin API, sticky monitoring)
+- **Crawl4AI containers**: FastAPI + Playwright browsers
+- **Redis**: Container discovery (heartbeats 30s), monitoring data aggregation
+- **Monitor**: Real-time dashboard at `/dashboard`
+
+## CLI Commands
+
+### Start/Stop
+```bash
+crwl server start [-r N] [--port P] [--mode auto|single|swarm|compose] [--env-file F] [--image I]
+crwl server stop [--remove-volumes]
+crwl server restart [-r N]
+```
+
+### Management
+```bash
+crwl server status        # Show mode, replicas, port, uptime
+crwl server scale N       # Live scaling (Swarm/Compose only)
+crwl server logs [-f] [--tail N]
+```
+
+**Defaults**: replicas=1, port=11235, mode=auto, image=unclecode/crawl4ai:latest
+
+## Deployment Modes
+
+| Replicas | Mode | Load Balancer | Use Case |
+|----------|------|---------------|----------|
+| N=1 | single | None | Dev/testing |
+| N>1 | swarm | Built-in | Production (if `docker swarm init` done) |
+| N>1 | compose | Nginx | Production (fallback) |
+
+**Mode Detection** (when mode=auto):
+1. If N=1 → single
+2. If N>1 & Swarm active → swarm
+3. If N>1 & Swarm inactive → compose
+
+## File Locations

+
+## Monitoring & Troubleshooting
+
+### Health Checks
+```bash
+curl http://localhost:11235/health              # Service health
+curl http://localhost:11235/monitor/containers  # Container discovery
+curl http://localhost:11235/monitor/requests    # Aggregated requests
+```
+
+### Dashboard
+- URL: `http://localhost:11235/dashboard/`
+- Features: Container filtering (All/C-1/C-2/C-3), real-time WebSocket, timeline charts
+- WebSocket: `/monitor/ws` (sticky sessions)
+
+### Common Issues
+
+**No containers showing in dashboard:**
+```bash
+docker exec <redis-container> redis-cli SMEMBERS monitor:active_containers
+docker exec <redis-container> redis-cli KEYS "monitor:heartbeat:*"
+```
+Wait 30s for heartbeat registration.
+
+**Load balancing not working:**
+```bash
+docker exec <nginx-container> cat /etc/nginx/nginx.conf | grep upstream
+docker logs <nginx-container> | grep error
+```
+Check Nginx upstream has no `ip_hash` for API endpoints.
+
+**Redis connection errors:**
+```bash
+docker logs <crawl4ai-container> | grep -i redis
+docker exec <crawl4ai-container> ping redis
+```
+Verify REDIS_HOST=redis, REDIS_PORT=6379.
+
+**Containers not scaling:**
+```bash
+# Swarm
+docker service ls
+docker service ps crawl4ai
+
+# Compose
+docker compose -f ~/.crawl4ai/server/docker-compose.yml ps
+docker compose -f ~/.crawl4ai/server/docker-compose.yml up -d --scale crawl4ai=N
+```
+
+### Redis Data Structure
+```
+monitor:active_containers              # SET: {container_ids}
+monitor:heartbeat:{cid}                # STRING: {id, hostname, last_seen} TTL=60s
+monitor:{cid}:active_requests          # STRING: JSON list, TTL=5min
+monitor:{cid}:completed                # STRING: JSON list, TTL=1h
+monitor:{cid}:janitor                  # STRING: JSON list, TTL=1h

+
+## Performance & Scaling
+
+### Resource Recommendations
+| Containers | Memory/Container | Total Memory | Use Case |
+|------------|-----------------|--------------|----------|
+| 1 | 4GB | 4GB | Development |
+| 3 | 4GB | 12GB | Small prod |
+| 5 | 4GB | 20GB | Medium prod |
+| 10 | 4GB | 40GB | Large prod |
+
+**Expected Throughput**: ~10 req/min per container (depends on crawl complexity)
+
+### Scaling Guidelines
+- **Horizontal**: Add replicas (`crwl server scale N`)
+- **Vertical**: Adjust `--memory 8G --cpus 4` in kwargs
+- **Browser Pool**: Permanent (1) + Hot pool (adaptive) + Cold pool (cleanup by janitor)
+
+### Redis Memory Usage
+- **Per container**: ~110KB (requests + events + errors + heartbeat)
+- **10 containers**: ~1.1MB
+- **Recommendation**: 256MB Redis is sufficient for <100 containers
+
+## Security Notes
+
+### Input Validation
+All CLI inputs validated:
+- Image name: alphanumeric + `.-/:_@` only, max 256 chars
+- Port: 1-65535
+- Replicas: 1-100
+- Env file: must exist and be readable
+- Container IDs: alphanumeric + `-_` only (prevents Redis injection)
+
+### Network Security
+- Nginx forwards to internal `crawl4ai` service (Docker network)
+- Monitor endpoints have NO authentication (add MONITOR_TOKEN env for security)
+- Redis is internal-only (no external port)
+
+### Recommended Production Setup
+```bash
+# Add authentication
+export MONITOR_TOKEN="your-secret-token"
+
+# Use Redis password
+redis:
+  command: redis-server --requirepass ${REDIS_PASSWORD}
+
+# Enable rate limiting in Nginx
+limit_req_zone $binary_remote_addr zone=api:10m rate=10r/s;
+```
+
+## Common User Scenarios
+
+### Scenario 1: Fresh Deployment
+```bash
+crwl server start --replicas 3 --env-file .env
+# Wait for health check, then access http://localhost:11235/health
+```
+
+### Scenario 2: Scaling Under Load
+```bash
+crwl server scale 10
+# Live scaling, no downtime
+```
+
+### Scenario 3: Debugging Slow Requests
+```bash
+# Check dashboard
+open http://localhost:11235/dashboard/
+
+# Check container logs
+docker logs <slowest-container-id> --tail 100
+
+# Check browser pool
+curl http://localhost:11235/monitor/browsers | jq
+```
+
+### Scenario 4: Redis Connection Issues
+```bash
+# Check Redis connectivity
+docker exec <crawl4ai-container> nc -zv redis 6379
+
+# Check Redis logs
+docker logs <redis-container>
+
+# Restart containers (triggers reconnect with retry logic)
+crwl server restart
+```
+
+### Scenario 5: Container Not Appearing in Dashboard
+```bash
+# Wait 30s for heartbeat
+sleep 30
+
+# Check Redis
+docker exec <redis-container> redis-cli SMEMBERS monitor:active_containers
+
+# Check container logs for heartbeat errors
+docker logs <missing-container> | grep -i heartbeat
+```
+
+## Code Context for Advanced Debugging
+
+### Key Classes
+- `MonitorStats` (monitor.py): Tracks stats, Redis persistence, heartbeat worker
+- `ServerManager` (server_manager.py): CLI orchestration, mode detection
+- Browser pool globals: `PERMANENT`, `HOT_POOL`, `COLD_POOL`, `LOCK` (crawler_pool.py)
+
+### Critical Timeouts
+- Browser pool lock: 2s timeout (prevents deadlock)
+- WebSocket connection: 5s timeout
+- Health check: 30-60s timeout
+- Heartbeat interval: 30s, TTL: 60s
+- Redis retry: 3 attempts, backoff: 0.5s/1s/2s
+- Circuit breaker: 5 failures → 5min backoff
+
+### State Transitions
+```
+NOT_RUNNING → STARTING → HEALTHY → RUNNING
+                ↓           ↓
+            FAILED      UNHEALTHY → STOPPED
+```
+
+State file: `~/.crawl4ai/server/state.json` (atomic writes, fcntl locking)
+
+## Quick Diagnostic Commands
+
+```bash
+# Full system check
+crwl server status
+docker ps
+curl http://localhost:11235/health
+curl http://localhost:11235/monitor/containers | jq
+
+# Redis check
+docker exec <redis-container> redis-cli PING
+docker exec <redis-container> redis-cli INFO stats
+
+# Network check
+docker network ls
+docker network inspect <network-name>
+
+# Logs check
+docker logs <nginx-container> --tail 50
+docker logs <redis-container> --tail 50
+docker compose -f ~/.crawl4ai/server/docker-compose.yml logs --tail 100
+```
+
+## Agent Decision Tree
+
+**User reports slow crawling:**
+1. Check dashboard for active requests stuck → kill browser if >5min
+2. Check browser pool status → cleanup if hot/cold pool >10
+3. Check container CPU/memory → scale up if >80%
+4. Check Redis latency → restart Redis if >100ms
+
+**User reports missing containers:**
+1. Wait 30s for heartbeat
+2. Check `docker ps` vs dashboard count
+3. Check Redis SMEMBERS monitor:active_containers
+4. Check container logs for Redis connection errors
+5. Verify REDIS_HOST/PORT env vars
+
+**User reports 502/503 errors:**
+1. Check Nginx logs for upstream errors
+2. Check container health: `curl http://localhost:11235/health`
+3. Check if all containers are healthy: `docker ps`
+4. Restart Nginx: `docker restart <nginx-container>`
+
+**User wants to update image:**
+1. `crwl server stop`
+2. `docker pull unclecode/crawl4ai:latest`
+3. `crwl server start --replicas <previous-count>`

+
+## Core Components Deep Dive
+
+### 1. `server_manager.py` - Orchestration Engine
+
+**Role:** Manages Docker container lifecycle, auto-detects deployment mode.
+
+**Key Classes:**
+- `ServerManager` - Main orchestrator
+  - `start(replicas, mode, port, env_file, image)` → Deploy server
+  - `stop(remove_volumes)` → Teardown
+  - `status()` → Health check
+  - `scale(replicas)` → Live scaling
+  - `logs(follow, tail)` → Stream logs
+  - `cleanup(force)` → Emergency cleanup
+
+**State Management:**
+- File: `~/.crawl4ai/server_state.yml`
+- Schema: `{mode, replicas, port, image, started_at, containers[]}`
+- Atomic writes with lock file
+
+**Deployment Modes:**
+```python
+if replicas == 1:
+    mode = "single"  # docker run
+elif swarm_available():
+    mode = "swarm"   # docker stack deploy
+else:
+    mode = "compose" # docker-compose + nginx
+```
+
+**Container Naming:**
+- Single: `crawl4ai-server`
+- Swarm: `crawl4ai-stack_crawl4ai`
+- Compose: `crawl4ai-server-{1..N}`, `crawl4ai-nginx`
+
+**Networks:**
+- `crawl4ai-network` (bridge mode for all)
+
+**Volumes:**
+- `crawl4ai-redis-data` - Persistent queue
+- `crawl4ai-profiles` - Browser profiles
+
+**Health Checks:**
+- Endpoint: `http://localhost:{port}/health`
+- Timeout: 30s startup
+- Retry: 3 attempts
+
+---
+
+### 2. `server.py` - FastAPI Application
+
+**Role:** HTTP server exposing crawl API + monitoring.
+
+**Startup Flow:**
+```python
+app = FastAPI()
+@app.on_event("startup")
+async def startup():
+    init_crawler_pool()      # Pre-warm browsers
+    init_redis_connection()  # Job queue
+    start_monitor_collector() # Metrics
+```
+
+**Key Endpoints:**
+```
+POST /crawl          → api.py:crawl_endpoint()
+POST /crawl/stream   → api.py:crawl_stream_endpoint()
+POST /screenshot     → api.py:screenshot_endpoint()
+POST /pdf            → api.py:pdf_endpoint()
+GET  /health         → server.py:health_check()
+GET  /monitor        → monitor_routes.py:dashboard()
+WS   /monitor/ws     → monitor_routes.py:websocket_endpoint()
+GET  /playground     → static/playground/index.html
+```
+
+**Process Manager:**
+- Uses `supervisord` to manage:
+  - FastAPI server (port 11235)
+  - Redis (port 6379)
+  - Background workers
+
+**Environment:**
+```bash
+CRAWL4AI_PORT=11235
+REDIS_URL=redis://localhost:6379
+MAX_CONCURRENT_CRAWLS=5
+BROWSER_POOL_SIZE=3
+```
+
+---
+
+### 3. `api.py` - Crawl Endpoints
+
+**Main Endpoint:** `POST /crawl`
+
+**Request Schema:**
+```json
+{
+  "urls": ["https://example.com"],
+  "priority": 10,
+  "browser_config": {
+    "type": "BrowserConfig",
+    "params": {"headless": true, "viewport_width": 1920}
+  },
+  "crawler_config": {
+    "type": "CrawlerRunConfig",
+    "params": {"cache_mode": "bypass", "extraction_strategy": {...}}
+  }
+}
+```
+
+**Processing Flow:**
+```
+1. Validate request (Pydantic)
+2. Queue job → Redis
+3. Get browser from pool → crawler_pool.py
+4. Execute crawl → AsyncWebCrawler
+5. Apply hooks → hook_manager.py
+6. Return result (JSON)
+7. Release browser to pool
+```
+
+**Memory Management:**
+- Browser pool: Max 3 instances
+- LRU eviction when pool full
+- Explicit cleanup: `browser.close()` in finally block
+- Redis TTL: 1 hour for completed jobs
+
+**Error Handling:**
+```python
+try:
+    result = await crawler.arun(url, config)
+except PlaywrightError as e:
+    # Browser crash - release & recreate
+    await pool.invalidate(browser_id)
+except TimeoutError as e:
+    # Timeout - kill & retry
+    await crawler.kill()
+except Exception as e:
+    # Unknown - log & fail gracefully
+    logger.error(f"Crawl failed: {e}")
+```
+
+---
+
+### 4. `crawler_pool.py` - Browser Pool Manager
+
+**Role:** Manage persistent browser instances to avoid startup overhead.
+
+**Class:** `CrawlerPool`
+- `get_crawler()` → Lease browser (async with context manager)
+- `release_crawler(id)` → Return to pool
+- `warm_up(count)` → Pre-launch browsers
+- `cleanup()` → Close all browsers
+
+**Pool Strategy:**
+```python
+pool = {
+    "browser_1": {"crawler": AsyncWebCrawler(), "in_use": False},
+    "browser_2": {"crawler": AsyncWebCrawler(), "in_use": False},
+    "browser_3": {"crawler": AsyncWebCrawler(), "in_use": False},
+}
+
+async with pool.get_crawler() as crawler:
+    result = await crawler.arun(url)
+    # Auto-released on context exit
+```
+
+**Anti-Leak Mechanisms:**
+1. Context managers enforce cleanup
+2. Watchdog thread kills stale browsers (>10min idle)
+3. Max lifetime: 1 hour per browser
+4. Force GC after browser close
+
+---
+
+### 5. `monitor.py` + `monitor_routes.py` - Real-time Dashboard
+
+**Architecture:**
+```
+[Browser] <--WebSocket--> [monitor_routes.py] <--Events--> [monitor.py]
+                              ↓
+                          [Redis Pub/Sub]
+                              ↓
+                       [Metrics Collector]
+```
+
+**Metrics Collected:**
+- Requests/sec (sliding window)
+- Active crawls (real-time count)
+- Response times (p50, p95, p99)
+- Error rate (5min rolling)
+- Memory usage (RSS, heap)
+- Browser pool utilization
+
+**WebSocket Protocol:**
+```json
+// Server → Client
+{
+  "type": "metrics",
+  "data": {
+    "rps": 45.3,
+    "active_crawls": 12,
+    "p95_latency": 1234,
+    "error_rate": 0.02
+  }
+}
+
+// Client → Server
+{
+  "type": "subscribe",
+  "channels": ["metrics", "logs"]
+}
+```
+
+**Dashboard Route:** `/monitor`
+- Real-time graphs (Chart.js)
+- Request log stream
+- Container health status
+- Resource utilization
+
+---
+
+### 6. `cnode_cli.py` - CLI Interface
+
+**Framework:** Click (Python CLI framework)
+
+**Command Structure:**
+```
+cnode
+├── start [--replicas N] [--port P] [--mode M] [--image I]
+├── stop [--remove-volumes]
+├── status
+├── scale N
+├── logs [--follow] [--tail N]
+├── restart [--replicas N]
+└── cleanup [--force]
+```
+
+**Execution Flow:**
+```python
+@cli.command("start")
+def start_cmd(replicas, mode, port, env_file, image):
+    manager = ServerManager()
+    result = anyio.run(manager.start(...))  # Async bridge
+    if result["success"]:
+        console.print(success_panel)
+```
+
+**User Feedback:**
+- Rich library for colors/tables
+- Progress spinners during operations
+- Error messages with hints
+- Status tables with health indicators
+
+**State Persistence:**
+- Saves deployment config to `~/.crawl4ai/server_state.yml`
+- Enables stateless commands (status, scale, restart)
+
+---
+
+### 7. Docker Orchestration Details
+
+**Single Container Mode (N=1):**
+```bash
+docker run -d \
+  --name crawl4ai-server \
+  --network crawl4ai-network \
+  -p 11235:11235 \
+  -v crawl4ai-redis-data:/data \
+  unclecode/crawl4ai:latest
+```
+
+**Docker Swarm Mode (N>1, Swarm available):**
+```yaml
+# docker-compose.swarm.yml
+version: '3.8'
+services:
+  crawl4ai:
+    image: unclecode/crawl4ai:latest
+    deploy:
+      replicas: 5
+      update_config:
+        parallelism: 2
+        delay: 10s
+      restart_policy:
+        condition: on-failure
+    ports:
+      - "11235:11235"
+    networks:
+      - crawl4ai-network
+```
+
+Deploy: `docker stack deploy -c docker-compose.swarm.yml crawl4ai-stack`
+
+**Docker Compose + Nginx Mode (N>1, fallback):**
+```yaml
+# docker-compose.yml
+services:
+  crawl4ai-1:
+    image: unclecode/crawl4ai:latest
+    networks: [crawl4ai-network]
+
+  crawl4ai-2:
+    image: unclecode/crawl4ai:latest
+    networks: [crawl4ai-network]
+
+  nginx:
+    image: nginx:alpine
+    ports: ["11235:80"]
+    volumes:
+      - ./nginx.conf:/etc/nginx/nginx.conf
+    networks: [crawl4ai-network]
+```
+
+Nginx config (round-robin load balancing):
+```nginx
+upstream crawl4ai_backend {
+    server crawl4ai-1:11235;
+    server crawl4ai-2:11235;
+    server crawl4ai-3:11235;
+}
+
+server {
+    listen 80;
+    location / {
+        proxy_pass http://crawl4ai_backend;
+        proxy_set_header Host $host;
+    }
+}
+```
+
+---
+
+## Memory Leak Prevention Strategy
+
+### Problem Areas & Solutions
+
+**1. Browser Instances**
+```python
+# ❌ BAD - Leak risk
+crawler = AsyncWebCrawler()
+result = await crawler.arun(url)
+# Browser never closed!
+
+# ✅ GOOD - Guaranteed cleanup
+async with AsyncWebCrawler() as crawler:
+    result = await crawler.arun(url)
+    # Auto-closed on exit
+```
+
+**2. WebSocket Connections**
+```python
+# monitor_routes.py
+active_connections = set()
+
+@app.websocket("/monitor/ws")
+async def websocket_endpoint(websocket):
+    await websocket.accept()
+    active_connections.add(websocket)
+    try:
+        while True:
+            await websocket.send_json(get_metrics())
+    finally:
+        active_connections.remove(websocket)  # Critical!
+```
+
+**3. Redis Connections**
+```python
+# Use connection pooling
+redis_pool = aioredis.ConnectionPool(
+    host="localhost",
+    port=6379,
+    max_connections=10,
+    decode_responses=True
+)
+
+# Reuse connections
+async def get_job(job_id):
+    async with redis_pool.get_connection() as conn:
+        data = await conn.get(f"job:{job_id}")
+    # Connection auto-returned to pool
+```
+
+**4. Async Task Cleanup**
+```python
+# Track background tasks
+background_tasks = set()
+
+async def crawl_task(url):
+    try:
+        result = await crawl(url)
+    finally:
+        background_tasks.discard(asyncio.current_task())
+
+# On shutdown
+async def shutdown():
+    tasks = list(background_tasks)
+    for task in tasks:
+        task.cancel()
+    await asyncio.gather(*tasks, return_exceptions=True)
+```
+
+**5. File Descriptor Leaks**
+```python
+# Use context managers for files
+async def save_screenshot(url):
+    async with aiofiles.open(f"{job_id}.png", "wb") as f:
+        await f.write(screenshot_bytes)
+    # File auto-closed
+```
+

+   exec python3 -m cnode_pkg.cli "$@"
+   ```
+9. Cleanup temp dir

+- Binary-like experience (fast startup: ~0.1s)
+- No need for PyInstaller (49x faster)
+- Platform-independent (any OS with Python)

+
+## Development Workflow
+
+### Source Code Sync (Auto)
+
+**Git Hook:** `.githooks/pre-commit`
+
+**Trigger:** When committing `deploy/docker/cnode_cli.py` or `server_manager.py`
+
+**Action:**
+```bash
+1. Diff source vs package
+2. If different:
+   - Run sync-cnode.sh
+   - Copy cnode_cli.py → cnode_pkg/cli.py
+   - Fix imports: s/deploy.docker/cnode_pkg/g
+   - Copy server_manager.py → cnode_pkg/
+   - Stage synced files
+3. Continue commit
+```
+
+**Setup:** `./setup-hooks.sh` (configures `git config core.hooksPath .githooks`)
+
+**Smart Behavior:**
+- Silent when no sync needed
+- Only syncs if content differs
+- Minimal output: `✓ cnode synced`
+

+
+## API Request/Response Flow
+
+### Example: POST /crawl
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "browser_config": {
+      "type": "BrowserConfig",
+      "params": {"headless": true}
+    },
+    "crawler_config": {
+      "type": "CrawlerRunConfig",
+      "params": {"cache_mode": "bypass"}
+    }
+  }'
+```
+
+**Processing:**
+```
+1. FastAPI receives request → api.py:crawl_endpoint()
+2. Validate schema → Pydantic models in schemas.py
+3. Create job → job.py:Job(id=uuid4(), urls=[...])
+4. Queue to Redis → LPUSH crawl_queue {job_json}
+5. Get browser from pool → crawler_pool.py:get_crawler()
+6. Execute crawl:
+   a. Launch page → browser.new_page()
+   b. Navigate → page.goto(url)
+   c. Extract → extraction_strategy.extract()
+   d. Generate markdown → markdown_generator.generate()
+7. Store result → Redis SETEX result:{job_id} 3600 {result_json}
+8. Release browser → pool.release(browser_id)
+9. Return response:
+   {
+     "success": true,
+     "result": {
+       "url": "https://example.com",
+       "markdown": "# Example Domain...",
+       "metadata": {"title": "Example Domain"},
+       "extracted_content": {...}
+     }
+   }
+```
+
+**Error Cases:**
+- 400: Invalid request schema
+- 429: Rate limit exceeded
+- 500: Internal error (browser crash, timeout)
+- 503: Service unavailable (all browsers busy)
+
+---
+
+## Scaling Behavior
+
+### Scale-Up (1 → 10 replicas)
+
+**Command:** `cnode scale 10`
+
+**Swarm Mode:**
+```bash
+docker service scale crawl4ai-stack_crawl4ai=10
+# Docker handles:
+# - Container creation
+# - Network attachment
+# - Load balancer update
+# - Rolling deployment
+```
+
+**Compose Mode:**
+```bash
+# Update docker-compose.yml
+# Change replica count in all service definitions
+docker-compose up -d --scale crawl4ai=10
+# Regenerate nginx.conf with 10 upstreams
+docker exec nginx nginx -s reload
+```
+
+**Load Distribution:**
+- Swarm: Built-in ingress network (VIP-based round-robin)
+- Compose: Nginx upstream (round-robin, can configure least_conn)
+
+**Zero-Downtime:**
+- Swarm: Yes (rolling update, parallelism=2)
+- Compose: Partial (nginx reload is graceful, but brief spike)

+### Asynchronous Jobs with Webhooks
+
+For long-running crawls or when you want to avoid keeping connections open, use the job queue endpoints. Instead of polling for results, configure a webhook to receive notifications when jobs complete.
+
+#### Why Use Jobs & Webhooks?
+
+- **No Polling Required** - Get notified when crawls complete instead of constantly checking status
+- **Better Resource Usage** - Free up client connections while jobs run in the background
+- **Scalable Architecture** - Ideal for high-volume crawling with TypeScript/Node.js clients or microservices
+- **Reliable Delivery** - Automatic retry with exponential backoff (5 attempts: 1s → 2s → 4s → 8s → 16s)
+
+#### How It Works
+
+1. **Submit Job** → POST to `/crawl/job` with optional `webhook_config`
+2. **Get Task ID** → Receive a `task_id` immediately
+3. **Job Runs** → Crawl executes in the background
+4. **Webhook Fired** → Server POSTs completion notification to your webhook URL
+5. **Fetch Results** → If data wasn't included in webhook, GET `/crawl/job/{task_id}`
+
+#### Quick Example
+
+```bash
+# Submit a crawl job with webhook notification
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false
+    }
+  }'
+
+# Response: {"task_id": "crawl_a1b2c3d4"}
+```
+
+**Your webhook receives:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"]
+}
+```
+
+Then fetch the results:
+```bash
+curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
+```
+
+#### Include Data in Webhook
+
+Set `webhook_data_in_payload: true` to receive the full crawl results directly in the webhook:
+
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Your webhook receives the complete data:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "data": {
+    "markdown": "...",
+    "html": "...",
+    "links": {...},
+    "metadata": {...}
+  }
+}
+```
+
+#### Webhook Authentication
+
+Add custom headers for authentication:
+
+```json
+{
+  "urls": ["https://example.com"],
+  "webhook_config": {
+    "webhook_url": "https://myapp.com/webhooks/crawl",
+    "webhook_data_in_payload": false,
+    "webhook_headers": {
+      "X-Webhook-Secret": "your-secret-token",
+      "X-Service-ID": "crawl4ai-prod"
+    }
+  }
+}
+```
+
+#### Global Default Webhook
+
+Configure a default webhook URL in `config.yml` for all jobs:
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"
+  data_in_payload: false
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000
+    max_delay_ms: 32000
+    timeout_ms: 30000
+```
+
+Now jobs without `webhook_config` automatically use the default webhook.
+
+#### Job Status Polling (Without Webhooks)
+
+If you prefer polling instead of webhooks, just omit `webhook_config`:
+
+```bash
+# Submit job
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{"urls": ["https://example.com"]}'
+# Response: {"task_id": "crawl_xyz"}
+
+# Poll for status
+curl http://localhost:11235/crawl/job/crawl_xyz
+```
+
+The response includes `status` field: `"processing"`, `"completed"`, or `"failed"`.
+
+#### LLM Extraction Jobs with Webhooks
+
+The same webhook system works for LLM extraction jobs via `/llm/job`:
+
+```bash
+# Submit LLM extraction job with webhook
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and main points",
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true,
+      "webhook_headers": {
+        "X-Webhook-Secret": "your-secret-token"
+      }
+    }
+  }'
+
+# Response: {"task_id": "llm_1234567890"}
+```
+
+**Your webhook receives:**
+```json
+{
+  "task_id": "llm_1234567890",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-22T12:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "main_points": ["Point 1", "Point 2", "Point 3"]
+    }
+  }
+}
+```
+
+**Key Differences for LLM Jobs:**
+- Task type is `"llm_extraction"` instead of `"crawl"`
+- Extracted data is in `data.extracted_content`
+- Single URL only (not an array)
+- Supports schema-based extraction with `schema` parameter
+
+> 💡 **Pro tip**: See [WEBHOOK_EXAMPLES.md](./WEBHOOK_EXAMPLES.md) for detailed examples including TypeScript client code, Flask webhook handlers, and failure handling.

+# Webhook Feature Examples
+
+This document provides examples of how to use the webhook feature for crawl jobs in Crawl4AI.
+
+## Overview
+
+The webhook feature allows you to receive notifications when crawl jobs complete, eliminating the need for polling. Webhooks are sent with exponential backoff retry logic to ensure reliable delivery.
+
+## Configuration
+
+### Global Configuration (config.yml)
+
+You can configure default webhook settings in `config.yml`:
+
+```yaml
+webhooks:
+  enabled: true
+  default_url: null  # Optional: default webhook URL for all jobs
+  data_in_payload: false  # Optional: default behavior for including data
+  retry:
+    max_attempts: 5
+    initial_delay_ms: 1000  # 1s, 2s, 4s, 8s, 16s exponential backoff
+    max_delay_ms: 32000
+    timeout_ms: 30000  # 30s timeout per webhook call
+  headers:  # Optional: default headers to include
+    User-Agent: "Crawl4AI-Webhook/1.0"
+```
+
+## API Usage Examples
+
+### Example 1: Basic Webhook (Notification Only)
+
+Send a webhook notification without including the crawl data in the payload.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false
+    }
+  }'
+```
+
+**Response:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4"
+}
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"]
+}
+```
+
+Your webhook handler should then fetch the results:
+```bash
+curl http://localhost:11235/crawl/job/crawl_a1b2c3d4
+```
+
+### Example 2: Webhook with Data Included
+
+Include the full crawl results in the webhook payload.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "data": {
+    "markdown": "...",
+    "html": "...",
+    "links": {...},
+    "metadata": {...}
+  }
+}
+```
+
+### Example 3: Webhook with Custom Headers
+
+Include custom headers for authentication or identification.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"],
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/crawl-complete",
+      "webhook_data_in_payload": false,
+      "webhook_headers": {
+        "X-Webhook-Secret": "my-secret-token",
+        "X-Service-ID": "crawl4ai-production"
+      }
+    }
+  }'
+```
+
+The webhook will be sent with these additional headers plus the default headers from config.
+
+### Example 4: Failure Notification
+
+When a crawl job fails, a webhook is sent with error details.
+
+**Webhook Payload on Failure:**
+```json
+{
+  "task_id": "crawl_a1b2c3d4",
+  "task_type": "crawl",
+  "status": "failed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com"],
+  "error": "Connection timeout after 30s"
+}
+```
+
+### Example 5: Using Global Default Webhook
+
+If you set a `default_url` in config.yml, jobs without webhook_config will use it:
+
+**config.yml:**
+```yaml
+webhooks:
+  enabled: true
+  default_url: "https://myapp.com/webhooks/default"
+  data_in_payload: false
+```
+
+**Request (no webhook_config needed):**
+```bash
+curl -X POST http://localhost:11235/crawl/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "urls": ["https://example.com"]
+  }'
+```
+
+The webhook will be sent to the default URL configured in config.yml.
+
+### Example 6: LLM Extraction Job with Webhook
+
+Use webhooks with the LLM extraction endpoint for asynchronous processing.
+
+**Request:**
+```bash
+curl -X POST http://localhost:11235/llm/job \
+  -H "Content-Type: application/json" \
+  -d '{
+    "url": "https://example.com/article",
+    "q": "Extract the article title, author, and publication date",
+    "schema": "{\"type\": \"object\", \"properties\": {\"title\": {\"type\": \"string\"}, \"author\": {\"type\": \"string\"}, \"date\": {\"type\": \"string\"}}}",
+    "cache": false,
+    "provider": "openai/gpt-4o-mini",
+    "webhook_config": {
+      "webhook_url": "https://myapp.com/webhooks/llm-complete",
+      "webhook_data_in_payload": true
+    }
+  }'
+```
+
+**Response:**
+```json
+{
+  "task_id": "llm_1698765432_12345"
+}
+```
+
+**Webhook Payload Received:**
+```json
+{
+  "task_id": "llm_1698765432_12345",
+  "task_type": "llm_extraction",
+  "status": "completed",
+  "timestamp": "2025-10-21T10:30:00.000000+00:00",
+  "urls": ["https://example.com/article"],
+  "data": {
+    "extracted_content": {
+      "title": "Understanding Web Scraping",
+      "author": "John Doe",
+      "date": "2025-10-21"
+    }
+  }
+}
+```
+
+## Webhook Handler Example
+
+Here's a simple Python Flask webhook handler that supports both crawl and LLM extraction jobs:
+
+```python
+from flask import Flask, request, jsonify
+import requests
+
+app = Flask(__name__)
+
+@app.route('/webhooks/crawl-complete', methods=['POST'])
+def handle_crawl_webhook():
+    payload = request.json
+
+    task_id = payload['task_id']
+    task_type = payload['task_type']
+    status = payload['status']
+
+    if status == 'completed':
+        # If data not in payload, fetch it
+        if 'data' not in payload:
+            # Determine endpoint based on task type
+            endpoint = 'crawl' if task_type == 'crawl' else 'llm'
+            response = requests.get(f'http://localhost:11235/{endpoint}/job/{task_id}')
+            data = response.json()
+        else:
+            data = payload['data']
+
+        # Process based on task type
+        if task_type == 'crawl':
+            print(f"Processing crawl results for {task_id}")
+            # Handle crawl results
+            results = data.get('results', [])
+            for result in results:
+                print(f"  - {result.get('url')}: {len(result.get('markdown', ''))} chars")
+
+        elif task_type == 'llm_extraction':
+            print(f"Processing LLM extraction for {task_id}")
+            # Handle LLM extraction
+            # Note: Webhook sends 'extracted_content', API returns 'result'
+            extracted = data.get('extracted_content', data.get('result', {}))
+            print(f"  - Extracted: {extracted}")
+
+        # Your business logic here...
+
+    elif status == 'failed':
+        error = payload.get('error', 'Unknown error')
+        print(f"{task_type} job {task_id} failed: {error}")
+        # Handle failure...
+
+    return jsonify({"status": "received"}), 200
+
+if __name__ == '__main__':
+    app.run(port=8080)
+```
+
+## Retry Logic
+
+The webhook delivery service uses exponential backoff retry logic:
+
+- **Attempts:** Up to 5 attempts by default
+- **Delays:** 1s → 2s → 4s → 8s → 16s
+- **Timeout:** 30 seconds per attempt
+- **Retry Conditions:**
+  - Server errors (5xx status codes)
+  - Network errors
+  - Timeouts
+- **No Retry:**
+  - Client errors (4xx status codes)
+  - Successful delivery (2xx status codes)
+
+## Benefits
+
+1. **No Polling Required** - Eliminates constant API calls to check job status
+2. **Real-time Notifications** - Immediate notification when jobs complete
+3. **Reliable Delivery** - Exponential backoff ensures webhooks are delivered
+4. **Flexible** - Choose between notification-only or full data delivery
+5. **Secure** - Support for custom headers for authentication
+6. **Configurable** - Global defaults or per-job configuration
+7. **Universal Support** - Works with both `/crawl/job` and `/llm/job` endpoints
+

+    body: JSON.stringify(request)
+  });
+
+  const { task_id } = await response.json();
+  return task_id;
+}
+
+// Usage - Crawl Job
+const crawlTaskId = await createCrawlJob({
+  urls: ['https://example.com'],
+  webhook_config: {
+    webhook_url: 'https://myapp.com/webhooks/crawl-complete',
+    webhook_data_in_payload: false,
+    webhook_headers: {
+      'X-Webhook-Secret': 'my-secret'
+    }
+  }
+});
+
+// Usage - LLM Extraction Job
+const llmTaskId = await createLLMJob({
+  url: 'https://example.com/article',
+  q: 'Extract the main points from this article',
+  provider: 'openai/gpt-4o-mini',
+  webhook_config: {
+    webhook_url: 'https://myapp.com/webhooks/llm-complete',
+    webhook_data_in_payload: true,
+    webhook_headers: {
+      'X-Webhook-Secret': 'my-secret'
+    }
+  }
+});
+```
+
+## Monitoring and Debugging
+
+Webhook delivery attempts are logged at INFO level:
+- Successful deliveries
+- Retry attempts with delays
+- Final failures after max attempts
+
+Check the application logs for webhook delivery status:
+```bash
+docker logs crawl4ai-container | grep -i webhook
+```

+# Crawl4AI Docker Memory & Pool Optimization - Implementation Log
+
+## Critical Issues Identified
+
+### Memory Management
+- **Host vs Container**: `psutil.virtual_memory()` reported host memory, not container limits
+- **Browser Pooling**: No pool reuse - every endpoint created new browsers
+- **Warmup Waste**: Permanent browser sat idle with mismatched config signature
+- **Idle Cleanup**: 30min TTL too long, janitor ran every 60s
+- **Endpoint Inconsistency**: 75% of endpoints bypassed pool (`/md`, `/html`, `/screenshot`, `/pdf`, `/execute_js`, `/llm`)
+
+### Pool Design Flaws
+- **Config Mismatch**: Permanent browser used `config.yml` args, endpoints used empty `BrowserConfig()`
+- **Logging Level**: Pool hit markers at DEBUG, invisible with INFO logging
+
+## Implementation Changes
+
+### 1. Container-Aware Memory Detection (`utils.py`)
+```python
+def get_container_memory_percent() -> float:
+    # Try cgroup v2 → v1 → fallback to psutil
+    # Reads /sys/fs/cgroup/memory.{current,max} OR memory/memory.{usage,limit}_in_bytes
+```
+
+### 2. Smart Browser Pool (`crawler_pool.py`)
+**3-Tier System:**
+- **PERMANENT**: Always-ready default browser (never cleaned)
+- **HOT_POOL**: Configs used 3+ times (longer TTL)
+- **COLD_POOL**: New/rare configs (short TTL)
+
+**Key Functions:**
+- `get_crawler(cfg)`: Check permanent → hot → cold → create new
+- `init_permanent(cfg)`: Initialize permanent at startup
+- `janitor()`: Adaptive cleanup (10s/30s/60s intervals based on memory)
+- `_sig(cfg)`: SHA1 hash of config dict for pool keys
+
+**Logging Fix**: Changed `logger.debug()` → `logger.info()` for pool hits
+
+### 3. Endpoint Unification
+**Helper Function** (`server.py`):
+```python
+def get_default_browser_config() -> BrowserConfig:
+    return BrowserConfig(
+        extra_args=config["crawler"]["browser"].get("extra_args", []),
+        **config["crawler"]["browser"].get("kwargs", {}),
+    )
+```
+
+**Migrated Endpoints:**
+- `/html`, `/screenshot`, `/pdf`, `/execute_js` → use `get_default_browser_config()`
+- `handle_llm_qa()`, `handle_markdown_request()` → same
+
+**Result**: All endpoints now hit permanent browser pool
+
+### 4. Config Updates (`config.yml`)
+- `idle_ttl_sec: 1800` → `300` (30min → 5min base TTL)
+- `port: 11234` → `11235` (fixed mismatch with Gunicorn)
+
+### 5. Lifespan Fix (`server.py`)
+```python
+await init_permanent(BrowserConfig(
+    extra_args=config["crawler"]["browser"].get("extra_args", []),
+    **config["crawler"]["browser"].get("kwargs", {}),
+))
+```
+Permanent browser now matches endpoint config signatures
+
+## Test Results
+
+### Test 1: Basic Health
+- 10 requests to `/health`
+- **Result**: 100% success, avg 3ms latency
+- **Baseline**: Container starts in ~5s, 270 MB idle
+
+### Test 2: Memory Monitoring
+- 20 requests with Docker stats tracking
+- **Result**: 100% success, no memory leak (-0.2 MB delta)
+- **Baseline**: 269.7 MB container overhead
+
+### Test 3: Pool Validation
+- 30 requests to `/html` endpoint
+- **Result**: **100% permanent browser hits**, 0 new browsers created
+- **Memory**: 287 MB baseline → 396 MB active (+109 MB)
+- **Latency**: Avg 4s (includes network to httpbin.org)
+
+### Test 4: Concurrent Load
+- Light (10) → Medium (50) → Heavy (100) concurrent
+- **Total**: 320 requests
+- **Result**: 100% success, **320/320 permanent hits**, 0 new browsers
+- **Memory**: 269 MB → peak 1533 MB → final 993 MB
+- **Latency**: P99 at 100 concurrent = 34s (expected with single browser)
+
+### Test 5: Pool Stress (Mixed Configs)
+- 20 requests with 4 different viewport configs
+- **Result**: 4 new browsers, 4 cold hits, **4 promotions to hot**, 8 hot hits
+- **Reuse Rate**: 60% (12 pool hits / 20 requests)
+- **Memory**: 270 MB → 928 MB peak (+658 MB = ~165 MB per browser)
+- **Proves**: Cold → hot promotion at 3 uses working perfectly
+
+### Test 6: Multi-Endpoint
+- 10 requests each: `/html`, `/screenshot`, `/pdf`, `/crawl`
+- **Result**: 100% success across all 4 endpoints
+- **Latency**: 5-8s avg (PDF slowest at 7.2s)
+
+### Test 7: Cleanup Verification
+- 20 requests (load spike) → 90s idle
+- **Memory**: 269 MB → peak 1107 MB → final 780 MB
+- **Recovery**: 327 MB (39%) - partial cleanup
+- **Note**: Hot pool browsers persist (by design), janitor working correctly
+
+## Performance Metrics
+
+| Metric | Before | After | Improvement |
+|--------|--------|-------|-------------|
+| Pool Reuse | 0% | 100% (default config) | ∞ |
+| Memory Leak | Unknown | 0 MB/cycle | Stable |
+| Browser Reuse | No | Yes | ~3-5s saved per request |
+| Idle Memory | 500-700 MB × N | 270-400 MB | 10x reduction |
+| Concurrent Capacity | ~20 | 100+ | 5x |
+
+## Key Learnings
+
+1. **Config Signature Matching**: Permanent browser MUST match endpoint default config exactly (SHA1 hash)
+2. **Logging Levels**: Pool diagnostics need INFO level, not DEBUG
+3. **Memory in Docker**: Must read cgroup files, not host metrics
+4. **Janitor Timing**: 60s interval adequate, but TTLs should be short (5min) for cold pool
+5. **Hot Promotion**: 3-use threshold works well for production patterns
+6. **Memory Per Browser**: ~150-200 MB per Chromium instance with headless + text_mode
+
+## Test Infrastructure
+
+**Location**: `deploy/docker/tests/`
+**Dependencies**: `httpx`, `docker` (Python SDK)
+**Pattern**: Sequential build - each test adds one capability
+
+**Files**:
+- `test_1_basic.py`: Health check + container lifecycle
+- `test_2_memory.py`: + Docker stats monitoring
+- `test_3_pool.py`: + Log analysis for pool markers
+- `test_4_concurrent.py`: + asyncio.Semaphore for concurrency control
+- `test_5_pool_stress.py`: + Config variants (viewports)
+- `test_6_multi_endpoint.py`: + Multiple endpoint testing
+- `test_7_cleanup.py`: + Time-series memory tracking for janitor
+
+**Run Pattern**:
+```bash
+cd deploy/docker/tests
+pip install -r requirements.txt
+# Rebuild after code changes:
+cd /path/to/repo && docker buildx build -t crawl4ai-local:latest --load .
+# Run test:
+python test_N_name.py
+```
+
+## Architecture Decisions
+
+**Why Permanent Browser?**
+- 90% of requests use default config → single browser serves most traffic
+- Eliminates 3-5s startup overhead per request
+
+**Why 3-Tier Pool?**
+- Permanent: Zero cost for common case
+- Hot: Amortized cost for frequent variants
+- Cold: Lazy allocation for rare configs
+
+**Why Adaptive Janitor?**
+- Memory pressure triggers aggressive cleanup
+- Low memory allows longer TTLs for better reuse
+
+**Why Not Close After Each Request?**
+- Browser startup: 3-5s overhead
+- Pool reuse: <100ms overhead
+- Net: 30-50x faster
+
+## Future Optimizations
+
+1. **Request Queuing**: When at capacity, queue instead of reject
+2. **Pre-warming**: Predict common configs, pre-create browsers
+3. **Metrics Export**: Prometheus metrics for pool efficiency
+4. **Config Normalization**: Group similar viewports (e.g., 1920±50 → 1920)
+
+## Critical Code Paths
+
+**Browser Acquisition** (`crawler_pool.py:34-78`):
+```
+get_crawler(cfg) →
+  _sig(cfg) →
+  if sig == DEFAULT_CONFIG_SIG → PERMANENT
+  elif sig in HOT_POOL → HOT_POOL[sig]
+  elif sig in COLD_POOL → promote if count >= 3
+  else → create new in COLD_POOL
+```
+
+**Janitor Loop** (`crawler_pool.py:107-146`):
+```
+while True:
+  mem% = get_container_memory_percent()
+  if mem% > 80: interval=10s, cold_ttl=30s
+  elif mem% > 60: interval=30s, cold_ttl=60s
+  else: interval=60s, cold_ttl=300s
+  sleep(interval)
+  close idle browsers (COLD then HOT)
+```
+
+**Endpoint Pattern** (`server.py` example):
+```python
+@app.post("/html")
+async def generate_html(...):
+    from crawler_pool import get_crawler
+    crawler = await get_crawler(get_default_browser_config())
+    results = await crawler.arun(url=body.url, config=cfg)
+    # No crawler.close() - returned to pool
+```
+
+## Debugging Tips
+
+**Check Pool Activity**:
+```bash
+docker logs crawl4ai-test | grep -E "(🔥|♨️|❄️|🆕|⬆️)"
+```
+
+**Verify Config Signature**:
+```python
+from crawl4ai import BrowserConfig
+import json, hashlib
+cfg = BrowserConfig(...)
+sig = hashlib.sha1(json.dumps(cfg.to_dict(), sort_keys=True).encode()).hexdigest()
+print(sig[:8])  # Compare with logs
+```
+
+**Monitor Memory**:
+```bash
+docker stats crawl4ai-test
+```
+
+## Known Limitations
+
+- **Mac Docker Stats**: CPU metrics unreliable, memory works
+- **PDF Generation**: Slowest endpoint (~7s), no optimization yet
+- **Hot Pool Persistence**: May hold memory longer than needed (trade-off for performance)
+- **Janitor Lag**: Up to 60s before cleanup triggers in low-memory scenarios

+## Test Execution Workflow
+
+Each test follows this pattern:
+
+1. **Setup:** Clean state, activate venv
+2. **Execute:** Run test commands
+3. **Verify:** Check results and assertions
+4. **Cleanup:** Stop server, remove resources
+
+## Running Individual Tests
+
+```bash
+# Make test executable (if needed)
+chmod +x deploy/docker/tests/cli/basic/test_01_start_default.sh
+
+# Run directly
+./deploy/docker/tests/cli/basic/test_01_start_default.sh
+
+# Or use the test runner
+./run_tests.sh basic 01
+```
+
+## Interpreting Results
+
+### Success Output
+```
+✅ Test passed: [description]
+```
+
+### Failure Output
+```
+❌ Test failed: [error message]
+```
+
+### Warning Output
+```
+⚠️  Warning: [issue description]
+```
+
+## Common Issues
+
+### Docker Not Running
+```
+Error: Docker daemon not running
+Solution: Start Docker Desktop or Docker daemon
+```
+
+### Port Already In Use
+```
+Error: Port 11235 is already in use
+Solution: Stop existing server or use different port
+```
+
+### Virtual Environment Not Found
+```
+Warning: venv not found
+Solution: Create venv and activate it
+```
+
+### Playwright Not Installed
+```
+Error: playwright module not found
+Solution: pip install playwright && playwright install chromium
+```
+
+## Test Development
+
+### Adding New Tests
+
+1. **Choose category:** basic, advanced, resource, dashboard, or edge
+2. **Create test file:** Follow naming pattern `test_XX_description.sh`
+3. **Use template:**
+
+```bash
+#!/bin/bash
+# Test: [Description]
+# Expected: [What should happen]
+
+set -e
+
+echo "=== Test: [Name] ==="
+echo ""
+
+source venv/bin/activate
+
+# Cleanup
+crwl server stop 2>/dev/null || true
+sleep 2
+
+# Test logic here
+
+# Cleanup
+crwl server stop >/dev/null 2>&1
+
+echo ""
+echo "✅ Test passed: [success message]"
+```
+
+4. **Make executable:** `chmod +x test_XX_description.sh`
+5. **Test it:** `./test_XX_description.sh`
+6. **Add to runner:** Tests are auto-discovered by `run_tests.sh`
+
+## CI/CD Integration
+
+These tests can be integrated into CI/CD pipelines:
+
+```yaml
+# Example GitHub Actions
+- name: Run CLI Tests
+  run: |
+    source venv/bin/activate
+    cd deploy/docker/tests/cli
+    ./run_tests.sh all
+```
+
+## Performance Considerations
+
+- **Basic tests:** ~2-5 minutes total
+- **Advanced tests:** ~5-10 minutes total
+- **Resource tests:** ~10-15 minutes total (including 5-min stability test)
+- **Dashboard test:** ~3-5 minutes
+- **Edge case tests:** ~5-8 minutes total
+
+**Full suite:** ~30-45 minutes
+
+## Best Practices
+
+1. **Always cleanup:** Each test should cleanup after itself
+2. **Wait for readiness:** Add sleep after starting servers
+3. **Check health:** Verify health endpoint before assertions
+4. **Graceful failures:** Use `|| true` to continue on expected failures
+5. **Clear messages:** Output should clearly indicate what's being tested
+
+## Troubleshooting
+
+### Tests Hanging
+- Check if Docker containers are stuck
+- Look for port conflicts
+- Verify network connectivity
+
+### Intermittent Failures
+- Increase sleep durations for slower systems
+- Check system resources (memory, CPU)
+- Verify Docker has enough resources allocated
+
+### All Tests Failing
+- Verify Docker is running: `docker ps`
+- Check CLI is installed: `which crwl`
+- Activate venv: `source venv/bin/activate`
+- Check server manager: `crwl server status`
+
+## Contributing
+
