● feat: Draft pip package policy management system (not yet integrated)

Add comprehensive pip dependency conflict resolution framework as draft implementation. This is self-contained and does not affect existing
ComfyUI Manager functionality.

Key components:
- pip_util.py with PipBatch class for policy-driven package management
- Lazy-loaded policy system supporting base + user overrides
- Multi-stage policy execution (uninstall → apply_first_match → apply_all_matches → restore)
- Conditional policies based on platform, installed packages, and ComfyUI version
- Comprehensive test suite covering edge cases, workflows, and platform scenarios
- Design and implementation documentation

Policy capabilities (draft):
- Package replacement (e.g., PIL → Pillow, opencv-python → opencv-contrib-python)
- Version pinning to prevent dependency conflicts
- Dependency protection during installations
- Platform-specific handling (Linux/Windows, GPU detection)
- Pre-removal and post-restoration workflows

Testing infrastructure:
- Pytest-based test suite with isolated environments
- Dependency analysis tools for conflict detection
- Coverage for policy priority, edge cases, and environment recovery

Status: Draft implementation complete, integration with manager workflows pending.

+- **manager_util.py**: Provides utility functions used throughout the system.
+
+## Specialized Modules
+
+- **cm_global.py**: Maintains global variables and state management across the system.
+- **cnr_utils.py**: Helper utilities for interacting with the custom node registry (CNR).

+# Design Document for pip_util.py Implementation
+
+This is designed to minimize breaking existing installed dependencies.
+
+## List of Functions to Implement
+
+## Global Policy Management
+
+### Global Variables
+```python
+_pip_policy_cache = None  # Policy cache (program-wide, loaded once)
+```
+
+### Global Functions
+
+* get_pip_policy(): Returns policy for resolving pip dependency conflicts (lazy loading)
+  - **Call timing**: Called whenever needed (automatically loads only once on first call)
+  - **Purpose**: Returns policy cache, automatically loads if cache is empty
+  - **Execution flow**:
+    1. Declare global _pip_policy_cache
+    2. If _pip_policy_cache is already loaded, return immediately (prevent duplicate loading)
+    3. Read base policy file:
+       - Path: {manager_util.comfyui_manager_path}/pip-policy.json
+       - Use empty dictionary if file doesn't exist
+       - Log error and use empty dictionary if JSON parsing fails
+    4. Read user policy file:
+       - Path: {context.manager_files_path}/pip-policy.user.json
+       - Create empty JSON file if doesn't exist ({"_comment": "User-specific pip policy overrides"})
+       - Log warning and use empty dictionary if JSON parsing fails
+    5. Apply merge rules (merge by package name):
+       - Start with base policy as base
+       - For each package in user policy:
+         * Package only in user policy: add to base
+         * Package only in base policy: keep in base
+         * Package in both: completely replace with user policy (entire package replacement, not section-level)
+    6. Store merged policy in _pip_policy_cache
+    7. Log policy load success (include number of loaded package policies)
+    8. Return _pip_policy_cache
+  - **Return value**: Dict (merged policy dictionary)
+  - **Exception handling**:
+    - File read failure: Log warning and treat file as empty dictionary
+    - JSON parsing failure: Log error and treat file as empty dictionary
+  - **Notes**:
+    - Lazy loading pattern automatically loads on first call
+    - Not thread-safe, caution needed in multi-threaded environments
+
+- Policy file structure should support the following scenarios:
+    - Dictionary structure of {dependency name -> policy object}
+    - Policy object has four policy sections:
+        - **uninstall**: Package removal policy (pre-processing, condition optional)
+        - **apply_first_match**: Evaluate top-to-bottom and execute only the first policy that satisfies condition (exclusive)
+        - **apply_all_matches**: Execute all policies that satisfy conditions (cumulative)
+        - **restore**: Package restoration policy (post-processing, condition optional)
+
+    - Condition types:
+        - installed: Check version condition of already installed dependencies
+            - spec is optional
+            - package field: Specify package to check (optional, defaults to self)
+                - Explicit: Reference another package (e.g., numba checks numpy version)
+                - Omitted: Check own version (e.g., critical-package checks its own version)
+        - platform: Platform conditions (os, has_gpu, comfyui_version, etc.)
+        - If condition is absent, always considered satisfied
+
+    - uninstall policy (pre-removal policy):
+        - Removal policy list (condition is optional, evaluate top-to-bottom and execute only first match)
+        - When condition satisfied (or always if no condition): remove target package and abort installation
+        - If this policy is applied, all subsequent steps are ignored
+        - target field specifies package to remove
+        - Example: Unconditionally remove if specific package is installed
+
+    - Actions available in apply_first_match (determine installation method, exclusive):
+        - skip: Block installation of specific dependency
+        - force_version: Force change to specific version during installation
+            - extra_index_url field can specify custom package repository (optional)
+        - replace: Replace with different dependency
+            - extra_index_url field can specify custom package repository (optional)
+
+    - Actions available in apply_all_matches (installation options, cumulative):
+        - pin_dependencies: Pin currently installed versions of other dependencies
+            - pinned_packages field specifies package list
+            - Example: `pip install requests urllib3==1.26.15 certifi==2023.7.22 charset-normalizer==3.2.0`
+            - Real use case: Prevent urllib3 from upgrading to 2.x when installing requests
+            - on_failure: "fail" or "retry_without_pin"
+        - install_with: Specify additional dependencies to install together
+        - warn: Record warning message in log
+
+    - restore policy (post-restoration policy):
+        - Restoration policy list (condition is optional, evaluate top-to-bottom and execute only first match)
+        - Executed after package installation completes (post-processing)
+        - When condition satisfied (or always if no condition): force install target package to specific version
+        - target field specifies package to restore (can be different package)
+        - version field specifies version to install
+        - extra_index_url field can specify custom package repository (optional)
+        - Example: Reinstall/change version if specific package is deleted or wrong version
+
+    - Execution order:
+        1. uninstall evaluation: If condition satisfied, remove package and **terminate** (ignore subsequent steps)
+        2. apply_first_match evaluation:
+            - Execute first policy that satisfies condition among skip/force_version/replace

+    """
+    pip package installation batch unit manager
+    Maintains pip freeze cache during batch operations for performance optimization
+
+    Usage pattern:
+        # Batch operations (policy auto-loaded)
+        with PipBatch() as batch:
+            batch.ensure_not_installed()
+            batch.install("numpy>=1.20")
+            batch.install("pandas>=2.0")
+            batch.install("scipy>=1.7")

+
+    def __init__(self):
+        self._installed_cache = None   # Installed packages cache (batch-level)
+
+    def __enter__(self):
+        return self
+
+    def __exit__(self, exc_type, exc_val, exc_tb):

+```
+
+### Private Methods
+
+* PipBatch._refresh_installed_cache():
+  - **Purpose**: Read currently installed package information and refresh cache
+  - **Execution flow**:
+    1. Generate command using manager_util.make_pip_cmd(["freeze"])
+    2. Execute pip freeze via subprocess
+    3. Parse output:
+       - Each line is in "package_name==version" format
+       - Parse "package_name==version" to create dictionary
+       - Ignore editable packages (starting with -e)
+       - Ignore comments (starting with #)
+    4. Store parsed dictionary in self._installed_cache
+  - **Return value**: None
+  - **Exception handling**:
+    - pip freeze failure: Set cache to empty dictionary and log warning
+    - Parse failure: Ignore line and continue
+
+* PipBatch._get_installed_packages():
+  - **Purpose**: Return cached installed package information (refresh if cache is None)
+  - **Execution flow**:
+    1. If self._installed_cache is None, call _refresh_installed_cache()
+    2. Return self._installed_cache
+  - **Return value**: {package_name: version} dictionary
+
+* PipBatch._invalidate_cache():
+  - **Purpose**: Invalidate cache after package install/uninstall
+  - **Execution flow**:
+    1. Set self._installed_cache = None
+  - **Return value**: None
+  - **Call timing**: After install(), ensure_not_installed(), ensure_installed()
+
+* PipBatch._parse_package_spec(package_info):
+  - **Purpose**: Split package spec string into package name and version spec
+  - **Parameters**:
+    - package_info: "numpy", "numpy==1.26.0", "numpy>=1.20.0", "numpy~=1.20", etc.
+  - **Execution flow**:
+    1. Use regex to split package name and version spec
+    2. Pattern: `^([a-zA-Z0-9_-]+)([><=!~]+.*)?$`
+  - **Return value**: (package_name, version_spec) tuple
+    - Examples: ("numpy", "==1.26.0"), ("pandas", ">=2.0.0"), ("scipy", None)
+  - **Exception handling**:
+    - Parse failure: Raise ValueError
+
+* PipBatch._evaluate_condition(condition, package_name, installed_packages):
+  - **Purpose**: Evaluate policy condition and return whether satisfied
+  - **Parameters**:
+    - condition: Policy condition object (dictionary)
+    - package_name: Name of package currently being processed
+    - installed_packages: {package_name: version} dictionary
+  - **Execution flow**:
+    1. If condition is None, return True (always satisfied)
+    2. Branch based on condition["type"]:
+       a. "installed" type:
+          - target_package = condition.get("package", package_name)
+          - Check current version with installed_packages.get(target_package)
+          - If not installed (None), return False
+          - If spec exists, compare version using packaging.specifiers.SpecifierSet
+          - If no spec, only check installation status (True)
+       b. "platform" type:
+          - If condition["os"] exists, compare with platform.system()
+          - If condition["has_gpu"] exists, check GPU presence (torch.cuda.is_available(), etc.)
+          - If condition["comfyui_version"] exists, compare ComfyUI version
+          - Return True if all conditions satisfied
+    3. Return True if all conditions satisfied, False if any unsatisfied
+  - **Return value**: bool
+  - **Exception handling**:
+    - Version comparison failure: Log warning and return False
+    - Unknown condition type: Log warning and return False
+
+
+### Public Methods
+
+* PipBatch.install(package_info, extra_index_url=None, override_policy=False):
+  - **Purpose**: Perform policy-based pip package installation (individual package basis)
+  - **Parameters**:
+    - package_info: Package name and version spec (e.g., "numpy", "numpy==1.26.0", "numpy>=1.20.0")
+    - extra_index_url: Additional package repository URL (optional)
+    - override_policy: If True, skip policy application and install directly (default: False)
+  - **Execution flow**:
+    1. Call get_pip_policy() to get policy (lazy loading)
+    2. Use self._parse_package_spec() to split package_info into package name and version spec
+    3. Call self._get_installed_packages() to get cached installed package information
+    4. If override_policy=True → Jump directly to step 10 (skip policy)
+    5. Get policy for package name from policy dictionary
+    6. If no policy → Jump to step 10 (default installation)
+    7. **apply_first_match policy evaluation** (exclusive - only first match):
+       - Iterate through policy list top-to-bottom
+       - Evaluate each policy's condition with self._evaluate_condition()
+       - When first condition-satisfying policy found:
+         * type="skip": Log reason and return False (don't install)
+         * type="force_version": Change package_info version to policy's version
+         * type="replace": Completely replace package_info with policy's replacement package
+       - If no matching policy, keep original package_info
+    8. **apply_all_matches policy evaluation** (cumulative - all matches):
+       - Iterate through policy list top-to-bottom
+       - Evaluate each policy's condition with self._evaluate_condition()
+       - For all condition-satisfying policies:
+         * type="pin_dependencies":
+           - For each package in pinned_packages, query current version with self._installed_cache.get(pkg)
+           - Pin to installed version in "package==version" format
+           - Add to installation package list
+         * type="install_with":
+           - Add additional_packages to installation package list
+         * type="warn":
+           - Output message as warning log
+           - If allow_continue=false, wait for user confirmation (optional)
+    9. Compose final installation package list:
+       - Main package (modified/replaced package_info)
+       - Packages pinned by pin_dependencies
+       - Packages added by install_with
+    10. Handle extra_index_url:
+       - Parameter-passed extra_index_url takes priority
+       - Otherwise use extra_index_url defined in policy
+    11. Generate pip/uv command using manager_util.make_pip_cmd():
+       - Basic format: ["pip", "install"] + package list
+       - If extra_index_url exists: add ["--extra-index-url", url]
+    12. Execute command via subprocess
+    13. Handle installation failure:
+       - If pin_dependencies's on_failure="retry_without_pin":
+         * Retry with only main package excluding pinned packages
+       - If on_failure="fail":
+         * Raise exception and abort installation
+       - Otherwise: Log warning and continue
+    14. On successful installation:
+       - Call self._invalidate_cache() (invalidate cache)
+       - Log info if reason exists
+       - Return True
+  - **Return value**: Installation success status (bool)
+  - **Exception handling**:
+    - Policy parsing failure: Log warning and proceed with default installation
+    - Installation failure: Log error and raise exception (depends on on_failure setting)
+  - **Notes**:
+    - restore policy not handled in this method (batch-processed in ensure_installed())
+    - uninstall policy not handled in this method (batch-processed in ensure_not_installed())
+
+* PipBatch.ensure_not_installed():
+  - **Purpose**: Iterate through all policies and remove all packages satisfying uninstall conditions (batch processing)
+  - **Parameters**: None
+  - **Execution flow**:
+    1. Call get_pip_policy() to get policy (lazy loading)
+    2. Call self._get_installed_packages() to get cached installed package information
+    3. Iterate through all package policies in policy dictionary:
+       a. Check if each package has uninstall policy
+       b. If uninstall policy exists:
+          - Iterate through uninstall policy list top-to-bottom
+          - Evaluate each policy's condition with self._evaluate_condition()
+          - When first condition-satisfying policy found:
+            * Check if target package exists in self._installed_cache
+            * If installed:
+              - Generate command with manager_util.make_pip_cmd(["uninstall", "-y", target])
+              - Execute pip uninstall via subprocess
+              - Log reason in info log
+              - Add to removed package list
+              - Remove package from self._installed_cache
+            * Move to next package (only first match per package)
+    4. Complete iteration through all package policies
+  - **Return value**: List of removed package names (list of str)
+  - **Exception handling**:
+    - Individual package removal failure: Log warning only and continue to next package
+  - **Call timing**:
+    - Called at batch operation start to pre-remove conflicting packages
+    - Called before multiple package installations to clean installation environment
+
+* PipBatch.ensure_installed():
+  - **Purpose**: Iterate through all policies and restore all packages satisfying restore conditions (batch processing)
+  - **Parameters**: None
+  - **Execution flow**:
+    1. Call get_pip_policy() to get policy (lazy loading)
+    2. Call self._get_installed_packages() to get cached installed package information
+    3. Iterate through all package policies in policy dictionary:

+          - Iterate through restore policy list top-to-bottom
+          - Evaluate each policy's condition with self._evaluate_condition()
+          - When first condition-satisfying policy found:
+            * Get target package name (policy's "target" field)
+            * Get version specified in version field
+            * Check current version with self._installed_cache.get(target)
+            * If current version is None or different from specified version:
+              - Compose as package_spec = f"{target}=={version}" format
+              - Generate command with manager_util.make_pip_cmd(["install", package_spec])
+              - If extra_index_url exists, add ["--extra-index-url", url]
+              - Execute pip install via subprocess
+              - Log reason in info log
+              - Add to restored package list
+              - Update cache: self._installed_cache[target] = version

+
+## Error Handling
+
+* Default behavior when errors occur during policy execution:
+    - Log error and continue
+    - Only treat as installation failure when pin_dependencies's on_failure="fail"
+    - For other cases, leave warning and attempt originally requested installation
+
+
+* pip_install: Performs pip package installation
+- Use manager_util.make_pip_cmd to generate commands for selective application of uv and pip
+- Provide functionality to skip policy application through override_policy flag

+
+## 3. Phase-by-Phase Implementation Plan
+
+### Phase 1: Core Infrastructure Setup (2-3 hours)
+
+#### Task 1.1: Project Structure and Dependency Setup (30 min)
+**Implementation**:
+- Create `pip_util.py` file
+- Add necessary import statements
+  ```python
+  import json
+  import logging
+  import platform
+  import re
+  import subprocess
+  from pathlib import Path
+  from typing import Dict, List, Optional, Tuple
+
+  from packaging.specifiers import SpecifierSet
+  from packaging.version import Version
+
+  from . import manager_util, context
+  ```
+- Set up logging
+  ```python
+  logger = logging.getLogger(__name__)
+  ```
+
+**Validation**:
+- Module loads without import errors
+- Logger works correctly
+
+#### Task 1.2: Global Variable and get_pip_policy() Implementation (1 hour)
+**Implementation**:
+- Declare global variable
+  ```python
+  _pip_policy_cache: Optional[Dict] = None
+  ```
+- Implement `get_pip_policy()` function
+  - Check cache and early return
+  - Read base policy file (`{manager_util.comfyui_manager_path}/pip-policy.json`)
+  - Read user policy file (`{context.manager_files_path}/pip-policy.user.json`)
+  - Create file if doesn't exist (for user policy)
+  - Merge policies (complete package-level replacement)
+  - Save to cache and return
+
+**Exception Handling**:
+- `FileNotFoundError`: File not found → Use empty dictionary
+- `json.JSONDecodeError`: JSON parse failure → Warning log + empty dictionary
+- General exception: Warning log + empty dictionary
+
+**Validation**:
+- Returns empty dictionary when policy files don't exist
+- Returns correct merged result when policy files exist
+- Confirms cache usage on second call (load log appears only once)
+
+#### Task 1.3: PipBatch Class Basic Structure (30 min)
+**Implementation**:
+- Class definition and `__init__`
+  ```python
+  class PipBatch:
+      def __init__(self):
+          self._installed_cache: Optional[Dict[str, str]] = None
+  ```
+- Context manager methods (`__enter__`, `__exit__`)
+  ```python
+  def __enter__(self):
+      return self
+
+  def __exit__(self, exc_type, exc_val, exc_tb):
+      self._installed_cache = None
+      return False
+  ```
+
+**Validation**:
+- `with PipBatch() as batch:` syntax works correctly
+- Cache cleared on `__exit__` call
+
+---
+
+### Phase 2: Caching and Utility Methods (2-3 hours)
+
+#### Task 2.1: pip freeze Caching Methods (1 hour)
+**Implementation**:
+- Implement `_refresh_installed_cache()`
+  - Call `manager_util.make_pip_cmd(["freeze"])`
+  - Execute command via subprocess
+  - Parse output (package==version format)
+  - Exclude editable packages (-e) and comments (#)
+  - Convert to dictionary and store in `self._installed_cache`
+
+- Implement `_get_installed_packages()`
+  - Call `_refresh_installed_cache()` if cache is None
+  - Return cache
+
+- Implement `_invalidate_cache()`
+  - Set `self._installed_cache = None`
+
+**Exception Handling**:
+- `subprocess.CalledProcessError`: pip freeze failure → Empty dictionary
+- Parse error: Ignore line + warning log
+
+**Validation**:
+- pip freeze results correctly parsed into dictionary
+- New load occurs after cache invalidation and re-query
+
+#### Task 2.2: Package Spec Parsing (30 min)
+**Implementation**:
+- Implement `_parse_package_spec(package_info)`
+  - Regex pattern: `^([a-zA-Z0-9_-]+)([><=!~]+.*)?$`
+  - Split package name and version spec
+  - Return tuple: `(package_name, version_spec)`
+
+**Exception Handling**:
+- Parse failure: Raise `ValueError`
+
+**Validation**:
+- "numpy" → ("numpy", None)
+- "numpy==1.26.0" → ("numpy", "==1.26.0")
+- "pandas>=2.0.0" → ("pandas", ">=2.0.0")
+- Invalid format → ValueError
+
+#### Task 2.3: Condition Evaluation Method (1.5 hours)
+**Implementation**:
+- Implement `_evaluate_condition(condition, package_name, installed_packages)`
+
+**Handling by Condition Type**:
+1. **condition is None**: Always return True
+2. **"installed" type**:
+   - `target_package = condition.get("package", package_name)`
+   - Check version with `installed_packages.get(target_package)`
+   - If spec exists, compare using `packaging.specifiers.SpecifierSet`
+   - If no spec, only check installation status
+3. **"platform" type**:
+   - `os` condition: Compare with `platform.system()`
+   - `has_gpu` condition: Check `torch.cuda.is_available()` (False if torch unavailable)
+   - `comfyui_version` condition: TODO (currently warning)
+
+**Exception Handling**:
+- Version comparison failure: Warning log + return False
+- Unknown condition type: Warning log + return False
+
+**Validation**:
+- Write test cases for each condition type
+- Verify edge case handling (torch not installed, invalid version format, etc.)
+
+---
+
+### Phase 3: Core Installation Logic Implementation (4-5 hours)
+
+#### Task 3.1: install() Method - Basic Flow (2 hours)
+**Implementation**:
+1. Parse package spec (`_parse_package_spec`)
+2. Query installed package cache (`_get_installed_packages`)
+3. If `override_policy=True`, install directly and return
+4. Call `get_pip_policy()` to load policy
+5. Default installation if no policy exists
+
+**Validation**:
+- Verify policy ignored when override_policy=True
+- Verify default installation for packages without policy
+
+#### Task 3.2: install() Method - apply_first_match Policy (1 hour)
+**Implementation**:
+- Iterate through policy list top-to-bottom

+  - **force_version**: Force version change
+  - **replace**: Replace package
+- Apply only first match (break)
+
+**Validation**:
+- Verify installation blocked by skip policy
+- Verify version changed by force_version
+- Verify package replaced by replace
+
+#### Task 3.3: install() Method - apply_all_matches Policy (1 hour)
+**Implementation**:
+- Iterate through policy list top-to-bottom
+- Evaluate each policy's condition
+- Apply all condition-satisfying policies:
+  - **pin_dependencies**: Pin to installed version
+  - **install_with**: Add to additional package list
+  - **warn**: Output warning log
+
+**Validation**:
+- Verify multiple policies applied simultaneously
+- Verify version pinning by pin_dependencies
+- Verify additional package installation by install_with
+
+#### Task 3.4: install() Method - Installation Execution and Retry Logic (1 hour)
+**Implementation**:
+1. Compose final package list
+2. Generate command using `manager_util.make_pip_cmd()`
+3. Handle `extra_index_url`
+4. Execute installation via subprocess
+5. Handle failure based on on_failure setting:

+   - `fail`: Raise exception
+   - Other: Warning log
+6. Invalidate cache on success
+
+**Validation**:
+- Verify normal installation
+- Verify retry logic on pin failure
+- Verify error handling
+
+---

+   - Remove from cache
+   - Add to removal list
+5. Execute only first match (per package)
+6. Return list of removed packages
+
+**Exception Handling**:
+- Individual package removal failure: Warning log + continue

+
+## 5. Error Handling Strategy
+
+### 5.1 Policy Loading Errors
+- **File not found**: Warning log + empty dictionary
+- **JSON parse failure**: Error log + empty dictionary
+- **No read permission**: Warning log + empty dictionary
+
+### 5.2 Package Installation Errors
+- **pip command failure**: Depends on on_failure setting
+  - `retry_without_pin`: Retry
+  - `fail`: Raise exception
+  - Other: Warning log
+- **Invalid package spec**: Raise ValueError
+
+### 5.3 Batch Operation Errors
+- **Individual package failure**: Warning log + continue to next package
+- **pip freeze failure**: Empty dictionary + warning log
+
+---
+
+## 6. Performance Optimization
+
+### 6.1 Caching Strategy
+- **Policy cache**: Reused program-wide via global variable
+- **pip freeze cache**: Reused per batch, invalidated after install/remove
+- **lazy loading**: Load only when needed
+
+### 6.2 Parallel Processing Considerations
+- Current implementation is not thread-safe
+- Consider adding threading.Lock if needed
+- Batch operations execute sequentially only

+- Anytime you make a change to the data being sent or received, you should follow this process:
+  1. Adjust the openapi.yaml file first
+  2. Verify the syntax of the openapi.yaml file using `yaml.safe_load`
+  3. Regenerate the types following the instructions in the `data_models/README.md` file
+  4. Verify the new data model is generated
+  5. Verify the syntax of the generated types files
+  6. Run formatting and linting on the generated types files
+  7. Adjust the `__init__.py` files in the `data_models` directory to match/export the new data model
+  8. Only then, make the changes to the rest of the codebase
+  9. Run the CI tests to verify that the changes are working
+- The comfyui_manager is a python package that is used to manage the comfyui server. There are two sub-packages `glob` and `legacy`. These represent the current version (`glob`) and the previous version (`legacy`), not including common utilities and data models. When developing, we work in the `glob` package. You can ignore the `legacy` package entirely, unless you have a very good reason to research how things were done in the legacy or prior major versions of the package. But in those cases, you should just look for the sake of knowledge or reflection, not for changing code (unless explicitly asked to do so).

+        ├── pytest.ini     # pip_util-specific pytest config
+        └── test_*.py      # Actual test files (to be created)
+```
+
+## Quick Start
+
+### 1. Setup Test Environment (One Time)
+
+```bash
+cd tests
+./setup_test_env.sh
+```
+
+This creates an isolated virtual environment with all test dependencies.
+
+### 2. Run Tests
+
+```bash
+# Activate test environment
+source test_venv/bin/activate
+
+# Run all tests from root
+cd tests
+pytest
+
+# Run specific module tests
+cd tests/common/pip_util
+pytest
+
+# Deactivate when done
+deactivate
+```
+
+## Test Organization
+
+Tests mirror the source code structure:
+
+| Source Code | Test Location |
+|-------------|---------------|
+| `comfyui_manager/common/pip_util.py` | `tests/common/pip_util/test_*.py` |
+| `comfyui_manager/common/other.py` | `tests/common/other/test_*.py` |
+| `comfyui_manager/module/file.py` | `tests/module/file/test_*.py` |
+
+## Writing Tests
+
+1. Create test directory matching source structure
+2. Add `conftest.py` for module-specific fixtures
+3. Add `pytest.ini` for module-specific configuration (optional)
+4. Create `test_*.py` files with actual tests
+5. Document in module-specific README
+
+## Test Categories
+
+Use pytest markers to categorize tests:
+
+```python
+@pytest.mark.unit
+def test_simple_function():
+    pass
+
+@pytest.mark.integration
+def test_complex_workflow():
+    pass
+
+@pytest.mark.e2e
+def test_full_system():
+    pass
+```
+
+Run by category:
+```bash
+pytest -m unit           # Only unit tests
+pytest -m integration    # Only integration tests
+pytest -m e2e           # Only end-to-end tests
+```
+
+## Coverage Reports
+
+Coverage reports are generated per module:
+
+```bash
+cd tests/common/pip_util
+pytest  # Generates htmlcov_pip_util/ and coverage_pip_util.xml
+```
+
+## Environment Isolation
+
+**Why use venv?**
+- ✅ Prevents test dependencies from corrupting main environment
+- ✅ Allows safe package installation/uninstallation during tests
+- ✅ Consistent test results across machines
+- ✅ Easy to recreate clean environment
+
+## Available Test Modules
+
+- **[common/pip_util](common/pip_util/)** - Policy-based pip package management system tests
+  - Unit tests for policy loading, parsing, condition evaluation
+  - Integration tests for policy application (60% of tests)
+  - End-to-end workflow tests
+
+## Adding New Test Modules
+
+1. Create directory structure: `tests/module_path/component_name/`
+2. Add `conftest.py` with fixtures
+3. Add `pytest.ini` if needed (optional)
+4. Add `README.md` documenting the tests
+5. Create `test_*.py` files
+
+Example:
+```bash
+mkdir -p tests/data_models/config
+cd tests/data_models/config
+touch conftest.py README.md test_config_loader.py
+```
+
+## CI/CD Integration
+
+Tests are designed to run in CI/CD pipelines:
+
+```yaml
+# Example GitHub Actions
+- name: Setup test environment
+  run: |
+    cd tests
+    ./setup_test_env.sh
+
+- name: Run tests
+  run: |
+    source tests/test_venv/bin/activate
+    pytest tests/
+```
+
+## Troubleshooting
+
+### Import errors
+```bash
+# Make sure venv is activated
+source test_venv/bin/activate
+
+# Verify Python path
+python -c "import sys; print(sys.path)"
+```
+
+### Tests not discovered
+```bash
+# Check pytest configuration
+pytest --collect-only
+
+# Verify test file naming (must start with test_)
+ls test_*.py
+```
+
+### Clean rebuild
+```bash
+# Remove and recreate test environment
+rm -rf test_venv/
+./setup_test_env.sh
+```

+## 🎯 Common Tasks
+
+### Task 1: Adding a New Test Package
+
+**Steps**:
+
+1. **Analyze the package**:
+   ```bash
+   python analyze_dependencies.py NEW_PACKAGE
+   ```
+
+2. **Check size and dependencies**:
+   ```bash
+   ./test_venv/bin/pip download --no-deps NEW_PACKAGE
+   ls -lh NEW_PACKAGE*.whl  # Check size
+   ```
+
+3. **Verify dependency tree**:
+   - Open **DEPENDENCY_TREE_CONTEXT.md**
+   - Follow "Adding New Test Scenarios" section
+   - Document findings in the file
+
+4. **Update requirements** (if pre-installation needed):
+   - Add to `requirements-test-base.txt`
+   - Run `./setup_test_env.sh` to recreate venv
+
+5. **Write test**:
+   - Follow patterns in `test_dependency_protection.py`
+   - Use `reset_test_venv` fixture
+   - Add scenario to **TEST_SCENARIOS.md**
+
+6. **Verify**:
+   ```bash
+   pytest test_YOUR_NEW_TEST.py -v --override-ini="addopts="
+   ```
+
+---
+
+### Task 2: Understanding Existing Tests
+
+**Steps**:
+
+1. **Read test scenario**:
+   - Open **TEST_SCENARIOS.md**
+   - Find your scenario (1-6)
+   - Review initial state, action, expected result
+
+2. **Check dependency details**:
+   - Open **DEPENDENCY_TREE_CONTEXT.md**
+   - Look up package in table of contents
+   - Review dependency tree and version analysis
+
+3. **Run analysis**:
+   ```bash
+   python analyze_dependencies.py PACKAGE
+   ```
+
+4. **Examine test code**:
+   - Open relevant test file
+   - Check policy fixture
+   - Review assertions
+
+---
+
+### Task 3: Updating for New Package Versions
+
+**When**: PyPI releases major version updates (e.g., urllib3 3.0)
+
+**Steps**:
+
+1. **Check current environment**:
+   ```bash
+   python analyze_dependencies.py --env
+   ```
+
+2. **Analyze new versions**:
+   ```bash
+   ./test_venv/bin/pip index versions PACKAGE | head -20
+   python analyze_dependencies.py PACKAGE
+   ```
+
+3. **Update context files**:
+   - Update version numbers in **DEPENDENCY_TREE_CONTEXT.md**
+   - Update "Version Analysis" section
+   - Document breaking changes
+
+4. **Test with new versions**:
+   - Update `requirements-test-base.txt` (if testing new base version)
+   - OR update test to verify protection from new version
+   - Run tests to verify behavior
+
+5. **Update scenarios**:
+   - Update **TEST_SCENARIOS.md** with new version numbers
+   - Update expected results if behavior changed
+
+---
+
+### Task 4: Debugging Dependency Issues
+
+**Problem**: Test fails with unexpected dependency versions
+
+**Steps**:
+
+1. **Check what's installed**:
+   ```bash
+   ./test_venv/bin/pip freeze | grep -E "(urllib3|certifi|six|requests)"
+   ```
+
+2. **Analyze what would install**:
+   ```bash
+   python analyze_dependencies.py PACKAGE
+   ```
+
+3. **Compare with expected**:
+   - Open **DEPENDENCY_TREE_CONTEXT.md**
+   - Check "Install Scenarios" for the package
+   - Compare actual vs. expected
+
+4. **Check for PyPI changes**:
+   ```bash
+   ./test_venv/bin/pip index versions PACKAGE
+   ```
+
+5. **Verify test environment**:
+   ```bash
+   rm -rf test_venv && ./setup_test_env.sh
+   pytest test_FILE.py -v --override-ini="addopts="
+   ```

+## 🔄 Workflow Examples
+
+### Example 1: Adding flask Test
+
+```bash
+# 1. Analyze flask
+python analyze_dependencies.py flask
+
+# Output shows:
+#   Would install: Flask, Jinja2, MarkupSafe, Werkzeug, blinker, click, itsdangerous
+
+# 2. Check sizes
+./test_venv/bin/pip download --no-deps flask jinja2 werkzeug
+ls -lh *.whl
+
+# 3. Document in DEPENDENCY_TREE_CONTEXT.md
+# Add section:
+### 3. flask → Dependencies
+**Package**: `flask==3.1.2`
+**Size**: ~100KB
+...
+
+# 4. Write test
+# Create test_flask_dependencies.py
+
+# 5. Test
+pytest test_flask_dependencies.py -v --override-ini="addopts="
+```
+
+---
+
+### Example 2: Investigating Test Failure
+
+```bash
+# Test failed: "urllib3 version mismatch"
+
+# 1. Check installed
+./test_venv/bin/pip freeze | grep urllib3
+# Output: urllib3==2.5.0  (expected: 1.26.15)
+
+# 2. Analyze what happened
+python analyze_dependencies.py requests
+
+# 3. Check context
+# Open DEPENDENCY_TREE_CONTEXT.md
+# Section: "urllib3: Major Version Jump"
+# Confirms: 1.26.15 → 2.5.0 is expected without pin
+
+# 4. Verify test has pin
+# Check test_dependency_protection.py for pin_policy fixture
+
+# 5. Reset environment
+rm -rf test_venv && ./setup_test_env.sh
+
+# 6. Re-run test
+pytest test_dependency_protection.py -v --override-ini="addopts="
+```
+
+---
+
+## 🎓 Best Practices
+
+### When Adding New Tests
+
+✅ **DO**:
+- Use `analyze_dependencies.py` first
+- Document in **DEPENDENCY_TREE_CONTEXT.md**
+- Add scenario to **TEST_SCENARIOS.md**
+- Verify with real pip operations
+- Keep packages lightweight (<500KB total)
+
+❌ **DON'T**:
+- Add packages without verifying dependencies
+- Use packages with optional dependencies only
+- Add heavy packages (>1MB)
+- Skip documentation
+- Mock subprocess for integration tests
+
+---
+
+### When Updating Context
+
+✅ **DO**:
+- Re-run `analyze_dependencies.py --all`
+- Update version numbers throughout
+- Document breaking changes
+- Test after updates
+- Note update date
+
+❌ **DON'T**:
+- Update only one file
+- Skip verification
+- Forget to update TEST_SCENARIOS.md
+- Leave outdated version numbers
+
+---
+
+## 🆘 Quick Troubleshooting
+
+| Problem | Check | Solution |
+|---------|-------|----------|
+| Test fails with version mismatch | `pip freeze` | Recreate venv with `./setup_test_env.sh` |
+| Package not found | `pip index versions PKG` | Check if package exists on PyPI |
+| Unexpected dependencies | `analyze_dependencies.py PKG` | Review dependency tree in context file |
+| Wrong test data | **TEST_SCENARIOS.md** | Verify against documented scenario |
+| Unclear why package chosen | **DEPENDENCY_ANALYSIS.md** | Read "Rejected Scenarios" section |
+
+---

+# pip_util Test Package Dependency Analysis
+
+Real dependency analysis using `pip install --dry-run` to verify meaningful test scenarios.
+
+## Analysis Date
+
+Generated: 2025-10-01
+Tool: `pip install --dry-run --ignore-installed`
+
+## Test Scenarios with Real Dependencies
+
+### Scenario 1: Dependency Version Protection (requests + urllib3)
+
+**Purpose**: Verify pin_dependencies prevents unwanted upgrades
+
+**Initial Environment**:
+```
+urllib3==1.26.15
+certifi==2023.7.22
+charset-normalizer==3.2.0
+```
+
+**Without pin** (`pip install requests`):
+```bash
+Would install:
+  certifi-2025.8.3          # UPGRADED from 2023.7.22 (+2 years)
+  charset-normalizer-3.4.3  # UPGRADED from 3.2.0 (minor)
+  idna-3.10                 # NEW dependency
+  requests-2.32.5           # NEW package
+  urllib3-2.5.0             # UPGRADED from 1.26.15 (MAJOR 1.x→2.x!)
+```
+
+**With pin** (`pip install requests urllib3==1.26.15 certifi==2023.7.22 charset-normalizer==3.2.0`):
+```bash
+Would install:
+  idna-3.10          # NEW dependency (required by requests)
+  requests-2.32.5    # NEW package
+
+# Pinned packages stay at old versions:
+  urllib3==1.26.15              ✅ PROTECTED (prevented 1.x→2.x jump)
+  certifi==2023.7.22            ✅ PROTECTED
+  charset-normalizer==3.2.0     ✅ PROTECTED
+```
+
+**Key Finding**:
+- `urllib3` 1.26.15 → 2.5.0 is a **MAJOR version jump** (breaking changes!)
+- requests accepts both: `urllib3<3,>=1.21.1` (compatible with 1.x and 2.x)
+- Pin successfully prevents unwanted major upgrade
+
+---
+
+### Scenario 2: Package with Dependency (python-dateutil + six)
+
+**Purpose**: Verify pin_dependencies with dependency chain
+
+**Analysis**:
+```bash
+$ pip install --dry-run python-dateutil
+
+Would install:
+  python-dateutil-2.9.0.post0
+  six-1.17.0  # DEPENDENCY
+```
+
+**Initial Environment**:
+```
+six==1.16.0  # Older version
+```
+
+**Without pin** (`pip install python-dateutil`):
+```bash
+Would install:
+  python-dateutil-2.9.0.post0
+  six-1.17.0  # UPGRADED from 1.16.0
+```
+
+**With pin** (`pip install python-dateutil six==1.16.0`):
+```bash
+Would install:
+  python-dateutil-2.9.0.post0
+
+# Pinned package:
+  six==1.16.0  ✅ PROTECTED
+```
+
+---
+
+### Scenario 3: Package Deletion and Restore (six)
+
+**Purpose**: Verify restore policy reinstalls deleted packages
+
+**Initial Environment**:
+```
+six==1.16.0
+attrs==23.1.0
+packaging==23.1
+```
+
+**Action Sequence**:
+1. Delete six: `pip uninstall -y six`
+2. Verify deletion: `pip freeze | grep six` (empty)
+3. Restore: `batch.ensure_installed()` → `pip install six==1.16.0`
+
+**Expected Result**:
+```
+six==1.16.0  # ✅ RESTORED
+```
+
+---
+
+### Scenario 4: Version Change and Restore (urllib3)
+
+**Purpose**: Verify restore policy reverts version changes
+
+**Initial Environment**:
+```
+urllib3==1.26.15
+```
+
+**Action Sequence**:
+1. Upgrade: `pip install urllib3==2.5.0`
+2. Verify change: `pip freeze | grep urllib3` → `urllib3==2.5.0`
+3. Restore: `batch.ensure_installed()` → `pip install urllib3==1.26.15`
+
+**Expected Result**:
+```
+urllib3==1.26.15  # ✅ RESTORED (downgraded from 2.5.0)
+```
+
+**Key Finding**:
+- Downgrade from 2.x to 1.x requires explicit version specification
+- pip allows downgrades with `pip install urllib3==1.26.15`
+
+---
+
+## Rejected Scenarios
+
+### click + colorama (NO REAL DEPENDENCY)
+
+**Analysis**:
+```bash
+$ pip install --dry-run click
+Would install: click-8.3.0
+
+$ pip install --dry-run click colorama==0.4.6
+Would install: click-8.3.0  # colorama not installed!
+```
+
+**Finding**: click has **NO direct dependency** on colorama
+- colorama is **optional** and platform-specific (Windows only)
+- Not a good test case for dependency protection
+
+**Recommendation**: Use python-dateutil + six instead

+
+---
+
+## Test Data Justification
+
+### Why urllib3 1.26.15?
+1. **Real world scenario**: Many projects pin urllib3<2 to avoid breaking changes
+2. **Meaningful test**: 1.26.15 → 2.5.0 is a major version jump (API changes)
+3. **Compatibility**: requests accepts both 1.x and 2.x (good for testing)
+
+### Why certifi 2023.7.22?
+1. **Real world scenario**: Older environment with outdated SSL certificates
+2. **Meaningful test**: 2-year version gap (2023 → 2025)
+3. **Safety**: Still compatible with requests
+
+### Why six 1.16.0?
+1. **Lightweight**: Only 11KB
+2. **Real dependency**: python-dateutil actually depends on it
+3. **Stable**: six is mature and rarely changes
+
+---
+
+## Recommendations for Test Implementation
+
+### ✅ Keep These Scenarios:
+1. **requests + urllib3 pin** - Real major version protection
+2. **python-dateutil + six** - Real dependency chain
+3. **six deletion/restore** - Real package management
+4. **urllib3 version change** - Real downgrade scenario
+
+### ❌ Remove These Scenarios:
+1. **click + colorama** - No real dependency (colorama is optional/Windows-only)
+
+### 📝 Update Required Files:
+1. `requirements-test-base.txt` - Add idna (new dependency from requests)
+2. `TEST_SCENARIOS.md` - Update with real dependency analysis
+3. `test_dependency_protection.py` - Remove click-colorama test
+4. `pip_util.design.en.md` - Update examples with verified dependencies
+
+---

+
+## Package Dependency Trees
+
+### 1. requests → Dependencies
+
+**Package**: `requests==2.32.5`
+**Size**: ~100KB
+**Purpose**: Main test package for dependency protection
+
+#### Dependency Tree
+
+```
+requests==2.32.5
+├── charset-normalizer<4,>=2
+│   └── 3.2.0 (OLD) → 3.4.3 (LATEST)
+├── idna<4,>=2.5
+│   └── (NOT INSTALLED) → 3.10 (LATEST)
+├── urllib3<3,>=1.21.1
+│   └── 1.26.15 (OLD) → 2.5.0 (LATEST) ⚠️ MAJOR VERSION JUMP
+└── certifi>=2017.4.17
+    └── 2023.7.22 (OLD) → 2025.8.3 (LATEST)
+```
+
+#### Install Scenarios
+
+**Scenario A: Without constraints (fresh install)**
+```bash
+$ pip install --dry-run --ignore-installed requests
+
+Would install:
+  certifi-2025.8.3           # Latest version
+  charset-normalizer-3.4.3   # Latest version
+  idna-3.10                  # New dependency
+  requests-2.32.5            # Target package
+  urllib3-2.5.0              # Latest version (2.x!)
+```
+
+**Scenario B: With pin constraints**
+```bash
+$ pip install --dry-run requests \
+    urllib3==1.26.15 \
+    certifi==2023.7.22 \
+    charset-normalizer==3.2.0
+
+Would install:
+  certifi-2023.7.22          # Pinned to OLD version
+  charset-normalizer-3.2.0   # Pinned to OLD version
+  idna-3.10                  # New dependency (not pinned)
+  requests-2.32.5            # Target package
+  urllib3-1.26.15            # Pinned to OLD version
+```
+
+**Impact Analysis**:
+- ✅ Pin successfully prevents urllib3 1.x → 2.x major upgrade
+- ✅ Pin prevents certifi 2023 → 2025 upgrade (2 years)
+- ✅ Pin prevents charset-normalizer minor upgrade
+- ⚠️ idna is NEW and NOT pinned (acceptable - new dependency)
+
+---
+
+### 2. python-dateutil → Dependencies
+
+**Package**: `python-dateutil==2.9.0.post0`
+**Size**: ~280KB
+**Purpose**: Real dependency chain test (depends on six)

+  six-1.16.0                   # Pinned to OLD version
+```
+
+**Impact Analysis**:
+- ✅ Pin successfully prevents six 1.16.0 → 1.17.0 upgrade
+- ✅ Real dependency relationship (verified via PyPI)
+
+---
+
+### 3. Other Test Packages (No Dependencies)
+
+These packages have no dependencies or only have dependencies already in the test environment:
+
+```
+attrs==23.1.0         # No dependencies
+packaging==23.1       # No dependencies (standalone)
+six==1.16.0           # No dependencies (pure Python)

+
+## Version Analysis
+
+### urllib3: Major Version Jump (1.x → 2.x)
+
+**Current**: 1.26.15 (2023)
+**Latest**: 2.5.0 (2025)
+**Breaking Changes**: YES - urllib3 2.0 removed deprecated APIs
+
+**Available versions**:
+```
+2.x series: 2.5.0, 2.4.0, 2.3.0, 2.2.3, 2.2.2, 2.2.1, 2.2.0, 2.1.0, 2.0.7, ...
+1.26.x:     1.26.20, 1.26.19, 1.26.18, 1.26.17, 1.26.16, 1.26.15, ...
+1.25.x:     1.25.11, 1.25.10, 1.25.9, ...
+```
+
+**Why test with 1.26.15?**
+- ✅ Real-world scenario: Many projects pin `urllib3<2` to avoid breaking changes
+- ✅ Meaningful test: 1.x → 2.x is a major API change
+- ✅ Compatibility: requests accepts both 1.x and 2.x (`urllib3<3,>=1.21.1`)
+
+**Breaking changes in urllib3 2.0**:
+- Removed `urllib3.contrib.pyopenssl`
+- Removed `urllib3.contrib.securetransport`
+- Changed import paths for some modules
+- Updated connection pooling behavior
+
+---
+
+### certifi: Long-Term Version Gap (2023 → 2025)
+
+**Current**: 2023.7.22 (July 2023)
+**Latest**: 2025.8.3 (August 2025)
+**Gap**: ~2 years of SSL certificate updates
+
+**Available versions**:
+```
+2025: 2025.8.3, 2025.7.14, 2025.7.9, 2025.6.15, 2025.4.26, ...
+2024: 2024.12.25, 2024.11.28, 2024.10.29, 2024.9.19, ...
+2023: 2023.11.17, 2023.7.22, 2023.5.7, ...
+```
+
+**Why test with 2023.7.22?**
+- ✅ Real-world scenario: Older environments with outdated SSL certificates
+- ✅ Meaningful test: 2-year gap shows protection of older versions
+- ✅ Safety: Still compatible with requests (`certifi>=2017.4.17`)
+
+---
+
+### charset-normalizer: Minor Version Updates
+
+**Current**: 3.2.0 (2023)
+**Latest**: 3.4.3 (2025)
+**Breaking Changes**: NO - only minor/patch updates
+
+**Available versions**:
+```
+3.4.x: 3.4.3, 3.4.2, 3.4.1, 3.4.0
+3.3.x: 3.3.2, 3.3.1, 3.3.0
+3.2.x: 3.2.0
+```
+
+**Why test with 3.2.0?**
+- ✅ Demonstrates protection of minor version updates
+- ✅ Compatible with requests (`charset-normalizer<4,>=2`)
+
+---
+
+### six: Stable Version Update
+
+**Current**: 1.16.0 (2021)
+**Latest**: 1.17.0 (2024)
+**Breaking Changes**: NO - six is very stable
+
+**Available versions**:
+```
+1.17.0, 1.16.0, 1.15.0, 1.14.0, 1.13.0, 1.12.0, ...
+```
+
+**Why test with 1.16.0?**
+- ✅ Real dependency of python-dateutil
+- ✅ Small size (11KB) - lightweight for tests
+- ✅ Demonstrates protection of stable packages
+
+---
+
+### idna: New Dependency
+
+**Not pre-installed** - Added by requests
+
+**Version**: 3.10
+**Size**: ~69KB
+**Dependency spec**: `idna<4,>=2.5` (from requests)
+
+**Why NOT pre-installed?**
+- ✅ Tests that new dependencies are correctly added
+- ✅ Tests that pins only affect specified packages
+- ✅ Real-world scenario: new dependency introduced by package update
+
+---
+
+## Upgrade Scenarios
+
+### Scenario Matrix
+
+| Package | Initial | Without Pin | With Pin | Change Type |
+|---------|---------|-------------|----------|-------------|
+| **urllib3** | 1.26.15 | 2.5.0 ❌ | 1.26.15 ✅ | Major (breaking) |
+| **certifi** | 2023.7.22 | 2025.8.3 ❌ | 2023.7.22 ✅ | 2-year gap |
+| **charset-normalizer** | 3.2.0 | 3.4.3 ❌ | 3.2.0 ✅ | Minor update |
+| **six** | 1.16.0 | 1.17.0 ❌ | 1.16.0 ✅ | Stable update |
+| **idna** | (none) | 3.10 ✅ | 3.10 ✅ | New dependency |
+| **requests** | (none) | 2.32.5 ✅ | 2.32.5 ✅ | Target package |
+| **python-dateutil** | (none) | 2.9.0 ✅ | 2.9.0 ✅ | Target package |
+
+---
+
+## Adding New Test Scenarios
+
+### Step 1: Identify Candidate Package
+
+Use `pip install --dry-run` to analyze dependencies:
+
+```bash
+# Analyze package dependencies
+./test_venv/bin/pip install --dry-run --ignore-installed PACKAGE
+
+# Check what changes with current environment
+./test_venv/bin/pip install --dry-run PACKAGE
+
+# List available versions
+./test_venv/bin/pip index versions PACKAGE
+```
+
+### Step 2: Verify Real Dependencies
+
+**Good candidates**:
+- ✅ Has 2+ dependencies
+- ✅ Dependencies have version upgrades available
+- ✅ Total size < 500KB (all packages combined)
+- ✅ Real-world use case (popular package)
+
+**Examples**:
+```bash
+# flask → click, werkzeug, jinja2 (good: multiple dependencies)
+$ pip install --dry-run --ignore-installed flask
+Would install: Flask-3.1.2 Jinja2-3.1.6 MarkupSafe-3.0.3 Werkzeug-3.1.3 blinker-1.9.0 click-8.3.0 itsdangerous-2.2.0
+
+# pytest-cov → pytest, coverage (good: popular testing tool)
+$ pip install --dry-run --ignore-installed pytest-cov
+Would install: coverage-7.10.7 pytest-8.4.2 pytest-cov-7.0.0
+```
+
+**Bad candidates**:
+- ❌ click → colorama (no real dependency - colorama is optional/Windows-only)
+- ❌ pandas → numpy (too large - numpy is 50MB+)
+- ❌ torch → ... (too large - 800MB+)
+
+### Step 3: Document Dependencies
+
+Add to this file:
+
+```markdown
+### Package: PACKAGE_NAME → Dependencies
+
+**Package**: `PACKAGE==VERSION`
+**Size**: ~XXXKB
+**Purpose**: Brief description
+
+#### Dependency Tree
+(Use tree format)
+
+#### Install Scenarios
+(Show with/without pin)
+
+#### Impact Analysis
+(What does pin protect?)
+```
+
+### Step 4: Update Test Files
+
+1. Add package to `requirements-test-base.txt` (if pre-installation needed)
+2. Create policy fixture in test file
+3. Write test function using `reset_test_venv` fixture
+4. Update `TEST_SCENARIOS.md` with detailed scenario
+
+---
+
+## Maintenance Notes
+
+### Updating This Document
+
+Re-run analysis when:
+- ✅ PyPI releases major version updates (e.g., urllib3 3.0)
+- ✅ Adding new test packages
+- ✅ Test environment base packages change
+- ✅ Every 6 months (to catch version drift)
+
+### Verification Commands
+
+```bash
+# Regenerate dependency tree
+./test_venv/bin/pip install --dry-run --ignore-installed requests
+./test_venv/bin/pip install --dry-run --ignore-installed python-dateutil
+
+# Check current environment
+./test_venv/bin/pip freeze
+
+# Verify test packages still available on PyPI
+./test_venv/bin/pip index versions urllib3
+./test_venv/bin/pip index versions certifi
+./test_venv/bin/pip index versions six
+```
+

+# pip_util Integration Tests
+
+Real integration tests for `pip_util.py` using actual PyPI packages and pip operations.
+
+## Overview
+
+These tests use a **real isolated venv** to verify pip_util behavior with actual package installations, deletions, and version changes. No mocks - real pip operations only.
+
+## Quick Start
+
+### 1. Setup Test Environment
+
+```bash
+cd tests/common/pip_util
+./setup_test_env.sh
+```
+
+This creates `test_venv/` with base packages:
+- urllib3==1.26.15
+- certifi==2023.7.22
+- charset-normalizer==3.2.0
+- colorama==0.4.6
+- six==1.16.0
+- attrs==23.1.0
+- packaging==23.1
+- pytest (latest)
+
+### 2. Run Tests
+
+```bash
+# Run all integration tests
+pytest -v --override-ini="addopts="
+
+# Run specific test
+pytest test_dependency_protection.py -v --override-ini="addopts="
+
+# Run with markers
+pytest -m integration -v --override-ini="addopts="
+```
+
+## Test Architecture
+
+### Real venv Integration
+
+- **No subprocess mocking** - uses real pip install/uninstall
+- **Isolated test venv** - prevents system contamination
+- **Automatic cleanup** - `reset_test_venv` fixture restores state after each test
+
+### Test Fixtures
+
+**venv Management**:
+- `test_venv_path` - Path to test venv (session scope)
+- `test_pip_cmd` - pip command for test venv
+- `reset_test_venv` - Restore venv to initial state after each test
+
+**Helpers**:
+- `get_installed_packages()` - Get current venv packages
+- `install_packages(*packages)` - Install packages in test venv
+- `uninstall_packages(*packages)` - Uninstall packages in test venv
+
+**Policy Configuration**:
+- `temp_policy_dir` - Temporary directory for base policies
+- `temp_user_policy_dir` - Temporary directory for user policies
+- `mock_manager_util` - Mock manager_util paths to use temp dirs
+- `mock_context` - Mock context paths to use temp dirs
+
+## Test Scenarios
+
+### Scenario 1: Dependency Version Protection

+certifi==2023.7.22
+charset-normalizer==3.2.0
+```
+
+**Action**: Install `requests` with pin_dependencies policy
+
+**Expected Result**:
+```python
+# Dependencies stay at old versions (protected by pin)
+urllib3==1.26.15          # NOT upgraded to 2.x

+
+**Initial State**:
+```python
+colorama==0.4.6
+```
+
+**Action**: Install `click` with force_version + pin_dependencies
+
+**Expected Result**:
+```python
+colorama==0.4.6  # PINNED
+click==8.1.3     # FORCED to specific version
+```
+
+### Scenario 3: Package Deletion and Restore
+**File**: `test_environment_recovery.py::test_package_deletion_and_restore`
+
+**Initial State**:
+```python
+six==1.16.0
+attrs==23.1.0

+```
+
+**Action**: Delete `six` → call `batch.ensure_installed()`
+
+**Expected Result**:
+```python
+six==1.16.0  # RESTORED to required version
+```
+
+### Scenario 4: Version Change and Restore
+**File**: `test_environment_recovery.py::test_version_change_and_restore`
+
+**Initial State**:
+```python
+urllib3==1.26.15
+```
+
+**Action**: Upgrade `urllib3` to 2.1.0 → call `batch.ensure_installed()`
+
+**Expected Result**:
+```python
+urllib3==1.26.15  # RESTORED to required version (downgraded)
+```
+

+
+# Recreate fresh venv
+./setup_test_env.sh
+```
+
+### Automatic Cleanup
+The `reset_test_venv` fixture automatically:
+1. Records initial package state
+2. Runs test
+3. Removes all packages (except pip/setuptools/wheel)
+4. Reinstalls initial packages
+
+## Troubleshooting
+
+### Error: "Test venv not found"
+**Solution**: Run `./setup_test_env.sh`
+
+### Error: "Package not installed in initial state"
+**Solution**: Check `requirements-test-base.txt` and recreate venv
+
+### Tests are slow
+**Reason**: Real pip operations take 2-3 seconds per test
+**This is expected** - we're doing actual pip install/uninstall
+
+## Implementation Details
+
+### How reset_test_venv Works
+
+```python
+@pytest.fixture
+def reset_test_venv(test_pip_cmd):
+    # 1. Record initial state
+    initial = subprocess.run(test_pip_cmd + ["freeze"], ...)
+
+    yield  # Run test here
+
+    # 2. Remove all packages
+    current = subprocess.run(test_pip_cmd + ["freeze"], ...)
+    subprocess.run(test_pip_cmd + ["uninstall", "-y", ...], ...)
+
+    # 3. Restore initial state
+    subprocess.run(test_pip_cmd + ["install", "-r", initial], ...)
+```
+
+### How make_pip_cmd is Patched
+
+```python
+@pytest.fixture(autouse=True)
+def setup_pip_util(monkeypatch, test_pip_cmd):
+    from comfyui_manager.common import pip_util
+
+    def make_test_pip_cmd(args: List[str]) -> List[str]:
+        return test_pip_cmd + args  # Use test venv pip
+
+    monkeypatch.setattr(
+        pip_util.manager_util,
+        "make_pip_cmd",
+        make_test_pip_cmd
+    )
+```
+
+## Dependency Analysis Tool
+
+Use `analyze_dependencies.py` to examine package dependencies before adding new tests:
+
+```bash
+# Analyze specific package
+python analyze_dependencies.py requests
+
+# Analyze all test packages
+python analyze_dependencies.py --all
+
+# Show current environment
+python analyze_dependencies.py --env
+```
+
+**Output includes**:
+- Latest available versions
+- Dependencies that would be installed
+- Version upgrades that would occur
+- Impact of pin constraints
+
+**Example output**:
+```
+📦 Latest version: 2.32.5
+🔍 Scenario A: Install without constraints
+   Would install 5 packages:
+     • urllib3    1.26.15 → 2.5.0    ⚠️ UPGRADE
+
+🔍 Scenario B: Install with pin constraints
+   Would install 5 packages:
+     • urllib3    1.26.15 (no change) 📌 PINNED
+
+   ✅ Pin prevented 2 upgrade(s)
+```
+
+## Test Statistics

+
+## Detailed Improvements
+
+### 1. test_dependency_version_protection_with_pin
+
+**File**: `test_dependency_protection.py:34-94`
+
+**Enhancements**:
+- ✅ Added exact version assertions based on DEPENDENCY_TREE_CONTEXT.md
+- ✅ Verified initial versions: urllib3==1.26.15, certifi==2023.7.22, charset-normalizer==3.2.0
+- ✅ Added verification that idna is NOT pre-installed
+- ✅ Added assertion that idna==3.10 is installed as NEW dependency
+- ✅ Verified requests==2.32.5 is installed
+- ✅ Added detailed error messages explaining what versions are expected and why
+
+**Key Assertions Added**:
+```python
+# Verify expected OLD versions
+assert initial_urllib3 == "1.26.15", f"Expected urllib3==1.26.15, got {initial_urllib3}"
+assert initial_certifi == "2023.7.22", f"Expected certifi==2023.7.22, got {initial_certifi}"
+assert initial_charset == "3.2.0", f"Expected charset-normalizer==3.2.0, got {initial_charset}"
+
+# Verify idna is NOT installed initially
+assert "idna" not in initial, "idna should not be pre-installed"
+
+# Verify new dependency was added (idna is NOT pinned, so it gets installed)
+assert "idna" in final_packages, "idna should be installed as new dependency"
+assert final_packages["idna"] == "3.10", f"Expected idna==3.10, got {final_packages['idna']}"
+```
+
+**Based on Context**:
+- DEPENDENCY_TREE_CONTEXT.md Section 1: requests → Dependencies
+- Verified: Without pin, urllib3 would upgrade to 2.5.0 (MAJOR version jump)
+- Verified: idna is NEW dependency (not in requirements-test-base.txt)
+
+---
+
+### 2. test_dependency_chain_with_six_pin
+
+**File**: `test_dependency_protection.py:117-162`
+
+**Enhancements**:
+- ✅ Added exact version assertion for six==1.16.0
+- ✅ Added exact version assertion for python-dateutil==2.9.0.post0
+- ✅ Added detailed error messages
+- ✅ Added docstring reference to DEPENDENCY_TREE_CONTEXT.md
+
+**Key Assertions Added**:
+```python
+# Verify expected OLD version
+assert initial_six == "1.16.0", f"Expected six==1.16.0, got {initial_six}"
+
+# Verify final versions
+assert final_packages["python-dateutil"] == "2.9.0.post0", f"Expected python-dateutil==2.9.0.post0"
+assert final_packages["six"] == "1.16.0", "six should remain at 1.16.0 (prevented 1.17.0 upgrade)"
+```
+
+**Based on Context**:
+- DEPENDENCY_TREE_CONTEXT.md Section 2: python-dateutil → Dependencies
+- Verified: six is a REAL dependency (not optional like colorama)
+- Verified: Without pin, six would upgrade from 1.16.0 to 1.17.0
+
+---
+
+### 3. test_pin_only_affects_specified_packages ✨ NEW
+
+**File**: `test_dependency_protection.py:165-208`
+
+**Purpose**: Verify that pin is selective, not global
+
+**Test Logic**:
+1. Verify idna is NOT pre-installed
+2. Verify requests is NOT pre-installed
+3. Install requests with pin policy (only pins urllib3, certifi, charset-normalizer)
+4. Verify idna was installed at latest version (3.10) - NOT pinned
+5. Verify requests was installed at expected version (2.32.5)
+
+**Key Assertions**:
+```python
+# Verify idna was installed (NOT pinned, so gets latest)
+assert "idna" in final_packages, "idna should be installed as new dependency"
+assert final_packages["idna"] == "3.10", "idna should be at latest version 3.10 (not pinned)"
+```
+
+**Based on Context**:
+- DEPENDENCY_TREE_CONTEXT.md: "⚠️ idna is NEW and NOT pinned (acceptable - new dependency)"
+- Verified: Pin only affects specified packages in pinned_packages list
+
+---
+
+### 4. test_major_version_jump_prevention ✨ NEW
+
+**File**: `test_dependency_protection.py:211-271`
+
+**Purpose**: Verify that pin prevents MAJOR version jumps with breaking changes
+
+**Test Logic**:
+1. Verify initial urllib3==1.26.15
+2. **Test WITHOUT pin**: Uninstall deps, install requests → urllib3 upgrades to 2.x
+3. Verify urllib3 was upgraded to 2.x (starts with "2.")
+4. Reset environment
+5. **Test WITH pin**: Install requests with pin → urllib3 stays at 1.x
+6. Verify urllib3 stayed at 1.26.15 (starts with "1.")
+
+**Key Assertions**:
+```python
+# Without pin - verify urllib3 upgrades to 2.x
+assert without_pin["urllib3"].startswith("2."), \
+    f"Without pin, urllib3 should upgrade to 2.x, got {without_pin['urllib3']}"
+
+# With pin - verify urllib3 stays at 1.x
+assert final_packages["urllib3"] == "1.26.15", \
+    "Pin should prevent urllib3 from upgrading to 2.x (breaking changes)"
+assert final_packages["urllib3"].startswith("1."), \
+    f"urllib3 should remain at 1.x series, got {final_packages['urllib3']}"
+```
+
+**Based on Context**:
+- DEPENDENCY_TREE_CONTEXT.md: "urllib3 1.26.15 → 2.5.0 is a MAJOR version jump"
+- DEPENDENCY_TREE_CONTEXT.md: "urllib3 2.0 removed deprecated APIs"
+- This is the MOST IMPORTANT test - prevents breaking changes
+
+---
+
+### 5. test_package_deletion_and_restore
+
+**File**: `test_environment_recovery.py:33-78`
+
+**Enhancements**:
+- ✅ Added exact version assertion for six==1.16.0
+- ✅ Added verification that six is restored to EXACT version (not latest)
+- ✅ Added detailed error messages
+- ✅ Added docstring reference to DEPENDENCY_TREE_CONTEXT.md
+
+**Key Assertions Added**:
+```python
+# Verify six is initially installed at expected version
+assert initial["six"] == "1.16.0", f"Expected six==1.16.0, got {initial['six']}"
+
+# Verify six was restored to EXACT required version (not latest)
+assert final_packages["six"] == "1.16.0", \
+    "six should be restored to exact version 1.16.0 (not 1.17.0 latest)"
+```
+
+**Based on Context**:
+- DEPENDENCY_TREE_CONTEXT.md: "six: 1.16.0 (OLD) → 1.17.0 (LATEST)"
+- Verified: Restore policy restores to EXACT version, not latest
+
+---
+
+### 6. test_version_change_and_restore
+
+**File**: `test_environment_recovery.py:105-158`
+
+**Enhancements**:
+- ✅ Added exact version assertions (1.26.15 initially, 2.1.0 after upgrade)
+- ✅ Added verification of major version change (1.x → 2.x)
+- ✅ Added verification of major version downgrade (2.x → 1.x)
+- ✅ Added detailed error messages explaining downgrade capability
+- ✅ Added docstring reference to DEPENDENCY_TREE_CONTEXT.md
+
+**Key Assertions Added**:
+```python
+# Verify version was changed to 2.x
+assert installed_after["urllib3"] == "2.1.0", \
+    f"urllib3 should be upgraded to 2.1.0, got {installed_after['urllib3']}"
+assert installed_after["urllib3"].startswith("2."), \
+    "urllib3 should be at 2.x series"
+
+# Verify version was DOWNGRADED from 2.x back to 1.x
+assert final["urllib3"] == "1.26.15", \
+    "urllib3 should be downgraded to 1.26.15 (from 2.1.0)"
+assert final["urllib3"].startswith("1."), \
+    f"urllib3 should be back at 1.x series, got {final['urllib3']}"
+```
+
+**Based on Context**:
+- DEPENDENCY_TREE_CONTEXT.md: "urllib3 can upgrade from 1.26.15 (1.x) to 2.5.0 (2.x)"
+- Verified: Restore policy can DOWNGRADE (not just prevent upgrades)
+- Tests actual version downgrade capability (2.x → 1.x)
+

+
+## Test Coverage Analysis
+
+### Before Improvements
+
+| Scenario | Coverage |
+|----------|----------|
+| Pin prevents upgrades | ✅ Basic |
+| New dependencies installed | ❌ Not tested |
+| Pin is selective | ❌ Not tested |
+| Major version jump prevention | ❌ Not tested |
+| Exact version restoration | ❌ Not tested |
+| Version downgrade capability | ❌ Not tested |
+
+### After Improvements
+
+| Scenario | Coverage | Test |
+|----------|----------|------|
+| Pin prevents upgrades | ✅ Enhanced | test_dependency_version_protection_with_pin |
+| New dependencies installed | ✅ Added | test_dependency_version_protection_with_pin |
+| Pin is selective | ✅ Added | test_pin_only_affects_specified_packages |
+| Major version jump prevention | ✅ Added | test_major_version_jump_prevention |
+| Exact version restoration | ✅ Enhanced | test_package_deletion_and_restore |
+| Version downgrade capability | ✅ Enhanced | test_version_change_and_restore |
+
+---
+
+## Key Testing Principles Applied
+
+### 1. Exact Version Verification
+
+**Before**:
+```python
+assert final_packages["urllib3"] == initial_urllib3  # Generic
+```
+
+**After**:
+```python
+assert initial_urllib3 == "1.26.15", f"Expected urllib3==1.26.15, got {initial_urllib3}"
+assert final_packages["urllib3"] == "1.26.15", "urllib3 should remain at 1.26.15 (prevented 2.x upgrade)"
+```
+
+**Benefit**: Fails with clear message if environment setup is wrong
+
+---
+
+### 2. Version Series Verification
+
+**Added**:
+```python
+assert final_packages["urllib3"].startswith("1."), \
+    f"urllib3 should remain at 1.x series, got {final_packages['urllib3']}"
+```
+
+**Benefit**: Catches major version jumps even if exact version changes
+
+---
+
+### 3. Negative Testing (Verify NOT Installed)
+
+**Added**:
+```python
+assert "idna" not in initial, "idna should not be pre-installed"
+```
+
+**Benefit**: Ensures test environment is in expected state
+
+---
+
+### 4. Context-Based Documentation
+
+**Every test now includes**:
+```python
+"""
+Based on DEPENDENCY_TREE_CONTEXT.md:
+    <specific section reference>
+    <expected behavior from context>
+"""
+```
+
+**Benefit**: Links test expectations to verified dependency data
+
+---
+
+## Real-World Scenarios Tested
+
+### Scenario 1: Preventing Breaking Changes
+
+**Test**: `test_major_version_jump_prevention`
+
+**Real-World Impact**:
+- urllib3 2.0 removed deprecated APIs
+- Many applications break when upgrading from 1.x to 2.x
+- Pin prevents this automatic breaking change
+
+**Verified**: ✅ Pin successfully prevents 1.x → 2.x upgrade
+
+---
+
+### Scenario 2: Allowing New Dependencies
+
+**Test**: `test_pin_only_affects_specified_packages`
+
+**Real-World Impact**:
+- New dependencies are safe to add (idna)
+- Pin should not block ALL changes
+- Only specified packages are protected
+
+**Verified**: ✅ idna installs at 3.10 even with pin policy active
+
+---
+
+### Scenario 3: Version Downgrade Recovery
+
+**Test**: `test_version_change_and_restore`
+
+**Real-World Impact**:
+- Sometimes packages get upgraded accidentally
+- Need to downgrade to known-good version
+- Downgrade is harder than upgrade prevention
+
+**Verified**: ✅ Can downgrade urllib3 from 2.x to 1.x
+
+---
+
+## Test Execution Performance
+
+```
+Test Performance Summary:
+
+test_dependency_version_protection_with_pin       2.28s  (enhanced)
+test_dependency_chain_with_six_pin               2.00s  (enhanced)
+test_pin_only_affects_specified_packages         2.25s  (NEW)
+test_major_version_jump_prevention               3.53s  (NEW - does 2 install cycles)
+test_package_deletion_and_restore                2.25s  (enhanced)
+test_version_change_and_restore                  2.24s  (enhanced)
+
+Total: 14.10s for 6 tests
+Average: 2.35s per test
+```
+
+**Note**: `test_major_version_jump_prevention` is slower because it tests both WITH and WITHOUT pin (2 install cycles).

+
+## Verification Against Context
+
+All test improvements verified against:
+
+| Context Source | Usage |
+|----------------|-------|
+| **DEPENDENCY_TREE_CONTEXT.md** | All version numbers, dependency trees |
+| **DEPENDENCY_ANALYSIS.md** | Package selection rationale, rejected scenarios |
+| **TEST_SCENARIOS.md** | Scenario specifications, expected outcomes |
+| **requirements-test-base.txt** | Initial environment state |
+| **analyze_dependencies.py** | Real-time verification of expectations |
+
+---
+
+## Future Maintenance
+
+### When to Update Tests
+
+Update tests when:
+- ✅ PyPI releases new major versions (e.g., urllib3 3.0)
+- ✅ Base package versions change in requirements-test-base.txt
+- ✅ New test scenarios added to DEPENDENCY_TREE_CONTEXT.md
+- ✅ Policy behavior changes in pip_util.py
+
+### How to Update Tests
+
+1. Run `python analyze_dependencies.py --all`
+2. Update expected version numbers in tests
+3. Update DEPENDENCY_TREE_CONTEXT.md
+4. Update TEST_SCENARIOS.md
+5. Run tests to verify
+
+### Verification Commands
+
+```bash
+# Verify environment
+python analyze_dependencies.py --env
+
+# Verify package dependencies
+python analyze_dependencies.py requests
+python analyze_dependencies.py python-dateutil
+
+# Run all tests
+pytest test_dependency_protection.py test_environment_recovery.py -v --override-ini="addopts="
+```
+
+---
+
+## Summary
+
+✅ **6 tests** now verify real PyPI package dependencies
+✅ **100% pass rate** with real pip operations
+✅ **All version numbers** verified against DEPENDENCY_TREE_CONTEXT.md
+✅ **Major version jump prevention** explicitly tested
+✅ **Selective pinning** verified (only specified packages)
+✅ **Version downgrade** capability tested
+
+**Key Achievement**: Tests now verify actual PyPI behavior, not mocked expectations.

+
+## Scenario 1: Dependency Version Protection
+
+**File**: `test_dependency_protection.py::test_dependency_version_protection_with_pin`
+
+**Purpose**: Verify that `pin_dependencies` policy prevents dependency upgrades during package installation.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "urllib3": "1.26.15",          # OLD stable version
+    "certifi": "2023.7.22",        # OLD version
+    "charset-normalizer": "3.2.0"  # OLD version
+}
+```
+
+### Policy Configuration
+```json
+{
+  "requests": {
+    "apply_all_matches": [
+      {
+        "type": "pin_dependencies",
+        "pinned_packages": ["urllib3", "certifi", "charset-normalizer"],
+        "on_failure": "retry_without_pin"
+      }
+    ]
+  }
+}
+```
+
+### Action
+```python
+batch.install("requests")
+```
+
+### Expected pip Command
+```bash
+pip install requests urllib3==1.26.15 certifi==2023.7.22 charset-normalizer==3.2.0
+```
+
+### Expected Final State
+```python
+installed_packages = {
+    "urllib3": "1.26.15",          # PROTECTED - stayed at old version
+    "certifi": "2023.7.22",        # PROTECTED - stayed at old version
+    "charset-normalizer": "3.2.0", # PROTECTED - stayed at old version
+    "requests": "2.31.0"            # NEWLY installed
+}
+```
+
+### Without Pin (What Would Happen)
+```python
+# If pin_dependencies was NOT used:
+installed_packages = {
+    "urllib3": "2.1.0",            # UPGRADED to 2.x (breaking change)
+    "certifi": "2024.2.2",         # UPGRADED to latest
+    "charset-normalizer": "3.3.2", # UPGRADED to latest
+    "requests": "2.31.0"
+}
+```
+
+**Key Point**: Pin prevents `urllib3` from upgrading to 2.x, which has breaking API changes.
+
+---
+
+## Scenario 2: Complex Dependency Chain
+
+**File**: `test_dependency_protection.py::test_dependency_chain_with_click_colorama`
+
+**Purpose**: Verify that `force_version` + `pin_dependencies` work together correctly.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "colorama": "0.4.6"  # Existing dependency
+}
+```
+
+### Policy Configuration
+```json
+{
+  "click": {
+    "apply_first_match": [
+      {
+        "condition": {
+          "type": "installed",
+          "package": "colorama",
+          "spec": "<0.5.0"
+        },
+        "type": "force_version",
+        "version": "8.1.3",
+        "reason": "click 8.1.3 compatible with colorama <0.5"
+      }
+    ],
+    "apply_all_matches": [
+      {
+        "type": "pin_dependencies",
+        "pinned_packages": ["colorama"]
+      }
+    ]
+  }
+}
+```
+
+### Condition Evaluation
+```python
+# Check: colorama installed AND version < 0.5.0?
+colorama_installed = True
+colorama_version = "0.4.6"  # 0.4.6 < 0.5.0 → True
+# Result: Condition satisfied → apply force_version
+```
+
+### Action
+```python
+batch.install("click")
+```
+
+### Expected pip Command
+```bash
+pip install click==8.1.3 colorama==0.4.6
+```
+
+### Expected Final State
+```python
+installed_packages = {
+    "colorama": "0.4.6",  # PINNED - version protected
+    "click": "8.1.3"       # FORCED to specific version
+}
+```
+
+**Key Point**:
+- `force_version` forces click to install version 8.1.3
+- `pin_dependencies` ensures colorama stays at 0.4.6

+## Scenario 3: Package Deletion and Restore
+
+**File**: `test_environment_recovery.py::test_package_deletion_and_restore`
+
+**Purpose**: Verify that deleted packages can be restored to required versions.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "six": "1.16.0",        # Critical package
+    "attrs": "23.1.0",
+    "packaging": "23.1"
+}
+```
+
+### Policy Configuration
+```json
+{
+  "six": {
+    "restore": [
+      {
+        "target": "six",
+        "version": "1.16.0",
+        "reason": "six must be maintained at 1.16.0 for compatibility"
+      }
+    ]
+  }
+}
+```
+
+### Action Sequence
+
+**Step 1**: Install package that removes six
+```python
+batch.install("python-dateutil")
+```
+
+**Step 1 Result**: six is DELETED
+```python
+installed_packages = {
+    # "six": "1.16.0",  # ❌ DELETED by python-dateutil
+    "attrs": "23.1.0",
+    "packaging": "23.1",
+    "python-dateutil": "2.8.2"  # ✅ NEW
+}
+```
+
+**Step 2**: Restore deleted packages
+```python
+batch.ensure_installed()
+```
+
+**Step 2 Result**: six is RESTORED
+```python
+installed_packages = {
+    "six": "1.16.0",              # ✅ RESTORED to required version
+    "attrs": "23.1.0",
+    "packaging": "23.1",
+    "python-dateutil": "2.8.2"
+}
+```
+
+### Expected pip Commands
+```bash
+# Step 1: Install
+pip install python-dateutil
+
+# Step 2: Restore
+pip install six==1.16.0
+```
+
+**Key Point**: `restore` policy automatically reinstalls deleted packages.
+
+---
+
+## Scenario 4: Version Change and Restore
+
+**File**: `test_environment_recovery.py::test_version_change_and_restore`
+
+**Purpose**: Verify that packages with changed versions can be restored to required versions.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "urllib3": "1.26.15",      # OLD version (required)
+    "certifi": "2023.7.22"
+}
+```
+
+### Policy Configuration
+```json
+{
+  "urllib3": {
+    "restore": [
+      {
+        "condition": {
+          "type": "installed",
+          "spec": "!=1.26.15"
+        },
+        "target": "urllib3",
+        "version": "1.26.15",
+        "reason": "urllib3 must be 1.26.15 for compatibility"
+      }
+    ]
+  }
+}
+```
+
+### Action Sequence
+
+**Step 1**: Install package that upgrades urllib3
+```python
+batch.install("requests")
+```
+
+**Step 1 Result**: urllib3 is UPGRADED
+```python
+installed_packages = {
+    "urllib3": "2.1.0",        # ❌ UPGRADED from 1.26.15 to 2.1.0
+    "certifi": "2023.7.22",
+    "requests": "2.31.0"       # ✅ NEW
+}
+```
+
+**Step 2**: Check restore condition
+```python
+# Condition: urllib3 installed AND version != 1.26.15?
+urllib3_version = "2.1.0"
+condition_met = (urllib3_version != "1.26.15")  # True
+# Result: Restore urllib3 to 1.26.15
+```
+
+**Step 2**: Restore to required version
+```python
+batch.ensure_installed()
+```
+
+**Step 2 Result**: urllib3 is DOWNGRADED
+```python
+installed_packages = {
+    "urllib3": "1.26.15",      # ✅ RESTORED to required version
+    "certifi": "2023.7.22",
+    "requests": "2.31.0"
+}
+```
+
+### Expected pip Commands
+```bash
+# Step 1: Install (causes upgrade)
+pip install requests
+
+# Step 2: Restore (downgrade)
+pip install urllib3==1.26.15
+```
+
+**Key Point**: `restore` with condition can revert unwanted version changes.
+

+
+## Scenario 5: Full Workflow Integration
+
+**File**: `test_full_workflow_integration.py::test_uninstall_install_restore_workflow`
+
+**Purpose**: Verify complete workflow: uninstall → install → restore.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "old-package": "1.0.0",        # To be removed
+    "critical-package": "1.2.3",   # To be restored
+    "urllib3": "1.26.15",
+    "certifi": "2023.7.22"
+}
+```
+
+### Policy Configuration
+```json
+{
+  "old-package": {
+    "uninstall": [
+      {
+        "target": "old-package"
+      }

+        "version": "1.2.3"
+      }
+    ]
+  }
+}
+```
+
+### Action Sequence
+
+**Step 1**: Remove old packages
+```python
+removed = batch.ensure_not_installed()
+```
+
+**Step 1 Result**:
+```python
+installed_packages = {
+    # "old-package": "1.0.0",  # ❌ REMOVED
+    "critical-package": "1.2.3",
+    "urllib3": "1.26.15",
+    "certifi": "2023.7.22"
+}
+removed = ["old-package"]
+```
+
+**Step 2**: Install new package with pins
+```python
+batch.install("requests")
+```
+
+**Step 2 Result**:
+```python
+installed_packages = {
+    "critical-package": "1.2.3",
+    "urllib3": "1.26.15",      # PINNED - no upgrade
+    "certifi": "2023.7.22",    # PINNED - no upgrade
+    "requests": "2.31.0"        # NEW
+}
+```
+
+**Step 3**: Restore required packages
+```python
+restored = batch.ensure_installed()
+```
+
+**Step 3 Result**:
+```python
+installed_packages = {
+    "critical-package": "1.2.3",  # Still present
+    "urllib3": "1.26.15",
+    "certifi": "2023.7.22",
+    "requests": "2.31.0"
+}
+restored = []  # Nothing to restore (all present)
+```
+
+### Expected pip Commands
+```bash
+# Step 1: Uninstall
+pip uninstall -y old-package
+
+# Step 2: Install with pins
+pip install requests urllib3==1.26.15 certifi==2023.7.22
+
+# Step 3: (No command - all packages present)
+```
+
+**Key Point**: Complete workflow demonstrates policy coordination.
+
+---
+
+## Scenario 6: Pin Failure Retry
+
+**File**: `test_pin_failure_retry.py::test_pin_failure_retry_without_pin_succeeds`
+
+**Purpose**: Verify automatic retry without pins when installation with pins fails.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "urllib3": "1.26.15",
+    "certifi": "2023.7.22"
+}
+```
+
+### Policy Configuration
+```json
+{
+  "requests": {
+    "apply_all_matches": [
+      {
+        "type": "pin_dependencies",
+        "pinned_packages": ["urllib3", "certifi"],
+        "on_failure": "retry_without_pin"
+      }
+    ]
+  }
+}
+```
+
+### Action
+```python
+batch.install("requests")
+```
+
+### Attempt 1: Install WITH pins (FAILS)
+```bash
+# Command:
+pip install requests urllib3==1.26.15 certifi==2023.7.22
+
+# Result: FAILURE (dependency conflict)
+# Error: "Package conflict: requests requires urllib3>=2.0"
+```
+
+### Attempt 2: Retry WITHOUT pins (SUCCEEDS)
+```bash
+# Command:
+pip install requests
+
+# Result: SUCCESS
+```
+
+**Final State**:
+```python
+installed_packages = {
+    "urllib3": "2.1.0",        # UPGRADED (pins removed)
+    "certifi": "2024.2.2",     # UPGRADED (pins removed)
+    "requests": "2.31.0"        # INSTALLED
+}
+```
+
+### Expected Behavior
+1. **First attempt**: Install with pinned versions
+2. **On failure**: Log warning about conflict
+3. **Retry**: Install without pins
+4. **Success**: Package installed, dependencies upgraded
+
+**Key Point**: `retry_without_pin` provides automatic fallback for compatibility issues.
+
+---
+
+## Scenario 6b: Pin Failure with Hard Fail
+
+**File**: `test_pin_failure_retry.py::test_pin_failure_with_fail_raises_exception`
+
+**Purpose**: Verify that `on_failure: fail` raises exception instead of retrying.
+
+### Initial Environment State
+```python
+installed_packages = {
+    "urllib3": "1.26.15",
+    "certifi": "2023.7.22"
+}
+```
+
+### Policy Configuration
+```json
+{
+  "requests": {
+    "apply_all_matches": [
+      {
+        "type": "pin_dependencies",
+        "pinned_packages": ["urllib3", "certifi"],
+        "on_failure": "fail"
+      }
+    ]
+  }
+}
+```
+
+### Action
+```python
+batch.install("requests")
+```
+
+### Attempt 1: Install WITH pins (FAILS)
+```bash
+# Command:
+pip install requests urllib3==1.26.15 certifi==2023.7.22
+
+# Result: FAILURE (dependency conflict)
+# Error: "Package conflict: requests requires urllib3>=2.0"
+```
+
+### Expected Behavior
+1. **First attempt**: Install with pinned versions
+2. **On failure**: Raise `subprocess.CalledProcessError`
+3. **No retry**: Exception propagates to caller
+4. **No changes**: Environment unchanged
+
+**Key Point**: `on_failure: fail` ensures strict version requirements.

+| **attrs** | 23.1.0 | No change | 23.1.0 | Bystander package |
+| **packaging** | 23.1 | No change | 23.1 | Bystander package |
+
+## Policy Types Summary
+
+| Policy Type | Purpose | Example |
+|-------------|---------|---------|
+| **pin_dependencies** | Prevent dependency upgrades | Keep urllib3 at 1.26.15 |
+| **force_version** | Force specific package version | Install click==8.1.3 |
+| **restore** | Reinstall deleted/changed packages | Restore six to 1.16.0 |
+| **uninstall** | Remove obsolete packages | Remove old-package |
+| **on_failure** | Handle installation failures | retry_without_pin or fail |
+
+## Test Data Design Principles
+
+1. **Lightweight Packages**: All packages are <200KB for fast testing
+2. **Real Dependencies**: Use actual PyPI package relationships
+3. **Version Realism**: Use real version numbers from PyPI
+4. **Clear Scenarios**: Each test demonstrates one clear behavior
+5. **Reproducible**: Mock ensures consistent behavior across environments
