refactor: remove package-level caching to support dynamic installation

Remove package-level caching in cnr_utils and node_package modules to enable
proper dynamic custom node installation and version switching without ComfyUI
server restarts.

Key Changes:
- Remove @lru_cache decorators from version-sensitive functions
- Remove cached_property from NodePackage for dynamic state updates
- Add comprehensive test suite with parallel execution support
- Implement version switching tests (CNR ↔ Nightly)
- Add case sensitivity integration tests
- Improve error handling and logging

API Priority Rules (manager_core.py:1801):
- Enabled-Priority: Show only enabled version when both exist
- CNR-Priority: Show only CNR when both CNR and Nightly are disabled
- Prevents duplicate package entries in /v2/customnode/installed API
- Cross-match using cnr_id and aux_id for CNR ↔ Nightly detection

Test Infrastructure:
- 8 test files with 59 comprehensive test cases
- Parallel test execution across 5 isolated environments
- Automated test scripts with environment setup
- Configurable timeout (60 minutes default)
- Support for both master and dr-support-pip-cm branches

Bug Fixes:
- Fix COMFYUI_CUSTOM_NODES_PATH environment variable export
- Resolve test fixture regression with module-level variables
- Fix import timing issues in test configuration
- Register pytest integration marker to eliminate warnings
- Fix POSIX compliance in shell scripts (((var++)) → $((var + 1)))

Documentation:
- CNR_VERSION_MANAGEMENT_DESIGN.md v1.0 → v1.1 with API priority rules
- Add test guides and execution documentation (TESTING_PROMPT.md)
- Add security-enhanced installation guide
- Create CLI migration guides and references
- Document package version management

+
+## Running Tests
+
+### Prerequisites
+
+1. Install test dependencies:
+```bash
+pip install pytest requests
+```
+
+2. Start ComfyUI server with Manager:
+```bash
+cd tests/env
+./run.sh
+```
+
+### Run All Tests
+
+```bash
+# From project root
+pytest tests/glob/ -v
+
+# With coverage
+pytest tests/glob/ -v --cov=comfyui_manager.glob --cov-report=html
+```
+
+### Run Specific Tests
+
+```bash
+# Run specific test file
+pytest tests/glob/test_queue_task_api.py -v
+
+# Run specific test function
+pytest tests/glob/test_queue_task_api.py::test_install_package_via_queue -v
+
+# Run with output
+pytest tests/glob/test_queue_task_api.py -v -s
+```
+
+## Environment Variables
+
+- `COMFYUI_TEST_URL` - Base URL for ComfyUI server (default: http://127.0.0.1:8188)
+- `TEST_SERVER_PORT` - Server port (default: 8188, automatically used by conftest.py)
+- `COMFYUI_CUSTOM_NODES_PATH` - Path to custom_nodes directory (default: tests/env/ComfyUI/custom_nodes)
+
+**Important**: All tests now use the `server_url` fixture from `conftest.py`, which reads from these environment variables. This ensures compatibility with parallel test execution.
+
+Example:
+```bash
+# Single test environment
+COMFYUI_TEST_URL=http://localhost:8188 pytest tests/glob/ -v
+
+# Parallel test environment (port automatically set)
+TEST_SERVER_PORT=8189 pytest tests/glob/ -v
+```

+
+## Known Issues and Fixes
+
+### Issue 1: Glob API Parameters
+**Important**: Glob API does NOT support `channel` or `mode` parameters.
+
+**Note**:
+- `channel` and `mode` parameters are legacy-only features
+- `InstallPackParams` data model includes these fields because it's shared between legacy and glob implementations
+- Glob API implementation ignores these parameters
+- Tests should NOT include `channel` or `mode` in request parameters
+
+### Issue 2: Case-Insensitive Package Operations (PARTIALLY RESOLVED)
+**Previous Problem**: Operations failed when using different cases (e.g., "ComfyUI_SigmoidOffsetScheduler" vs "comfyui_sigmoidoffsetscheduler")
+
+**Current Status**:
+- **Install**: Requires exact package name due to CNR server limitations (case-sensitive)
+- **Uninstall/Enable/Disable**: Works with any case variation using `cnr_utils.normalize_package_name()`
+
+**Normalization Function** (`cnr_utils.normalize_package_name()`):
+- Strips leading/trailing whitespace with `.strip()`
+- Converts to lowercase with `.lower()`
+- Accepts any case variation (e.g., "ComfyUI_SigmoidOffsetScheduler", "COMFYUI_SIGMOIDOFFSETSCHEDULER", " comfyui_sigmoidoffsetscheduler ")
+
+**Examples**:
+```python
+# Install - requires exact case
+{"id": "ComfyUI_SigmoidOffsetScheduler"}  # ✓ Works
+{"id": "comfyui_sigmoidoffsetscheduler"}  # ✗ Fails (CNR limitation)
+
+# Uninstall - accepts any case
+{"node_name": "ComfyUI_SigmoidOffsetScheduler"}  # ✓ Works
+{"node_name": " ComfyUI_SigmoidOffsetScheduler "}  # ✓ Works (normalized)
+{"node_name": "COMFYUI_SIGMOIDOFFSETSCHEDULER"}  # ✓ Works (normalized)
+{"node_name": "comfyui_sigmoidoffsetscheduler"}  # ✓ Works (normalized)
+```
+
+### Issue 3: `.disabled/` Directory Mechanism
+**Critical Discovery**: The `.disabled/` directory is used by the **disable** operation to store disabled packages.
+
+**Implementation** (manager_core.py:1115-1154):
+```python
+def unified_disable(self, packname: str):
+    # Disable moves package to .disabled/ with version suffix
+    to_path = os.path.join(base_path, '.disabled', f"{folder_name}@{matched_active.version.replace('.', '_')}")
+    shutil.move(matched_active.fullpath, to_path)
+```
+
+**Directory Naming Format**:
+- CNR packages: `.disabled/{package_name_normalized}@{version}`
+  - Example: `.disabled/comfyui_sigmoidoffsetscheduler@1_0_2`
+- Nightly packages: `.disabled/{package_name_normalized}@nightly`
+  - Example: `.disabled/comfyui_sigmoidoffsetscheduler@nightly`
+
+**Key Points**:
+- Package names are **normalized** (lowercase) in directory names
+- Version dots are **replaced with underscores** (e.g., `1.0.2` → `1_0_2`)
+- Disabled packages **preserve** their marker files (`.tracking` for CNR, `.git` for Nightly)
+- Enable operation **moves packages back** from `.disabled/` to `custom_nodes/`
+
+**Testing Implications**:
+- Complex multi-version scenarios require **install → disable** sequences
+- Fixture pattern: Install CNR → Disable → Install Nightly → Disable
+- Tests must check `.disabled/` with **case-insensitive** searches
+- Directory format must match normalized names with version suffixes
+
+### Issue 4: Version Switch Mechanism
+**Behavior**: Version switching uses a **slot-based system** with Nightly and Archive as separate slots.
+
+**Slot-Based System Concept**:
+- **Nightly Slot**: Git-based installation (one slot)
+- **Archive Slot**: Registry-based installation (one slot)
+- Only **one slot is active** at a time
+- The inactive slot is stored in `.disabled/`
+- Archive versions update **within the Archive slot**
+
+**Two Types of Version Switch**:
+
+**1. Slot Switch: Nightly ↔ Archive (uses `.disabled/` mechanism)**
+- **Archive → Nightly**:
+  - Archive (any version) → moved to `.disabled/ComfyUI_SigmoidOffsetScheduler`
+  - Nightly → active in `custom_nodes/ComfyUI_SigmoidOffsetScheduler`
+
+- **Nightly → Archive**:
+  - Nightly → moved to `.disabled/ComfyUI_SigmoidOffsetScheduler`
+  - Archive (any version) → **restored from `.disabled/`** and becomes active
+
+**2. Version Update: Archive ↔ Archive (in-place update within Archive slot)**
+- **1.0.1 → 1.0.2** (when Archive slot is active):
+  - Directory contents updated in-place
+  - pyproject.toml version updated: 1.0.1 → 1.0.2
+  - `.tracking` file updated
+  - NO `.disabled/` directory used
+
+**3. Combined Operation: Nightly (active) + Archive 1.0 (disabled) → Archive 2.0**
+- **Step 1 - Slot Switch**: Nightly → `.disabled/`, Archive 1.0 → active
+- **Step 2 - Version Update**: Archive 1.0 → 2.0 (in-place within Archive slot)
+- **Result**: Archive 2.0 active, Nightly in `.disabled/`
+
+**Version Identification**:
+- **Archive versions**: Use `pyproject.toml` version field
+- **Nightly version**: pyproject.toml **ignored**, Git commit SHA used instead
+
+**Key Points**:
+- **Slot Switch** (Nightly ↔ Archive): `.disabled/` mechanism for enable/disable
+- **Version Update** (Archive ↔ Archive): In-place content update within slot
+- Archive installations have `.tracking` file
+- Nightly installations have `.git` directory
+- Only one slot is active at a time
+
+### Issue 5: Version Selection Logic (RESOLVED)
+**Problem**: When enabling a package with both CNR and Nightly versions disabled, the system would always enable CNR instead of respecting the user's choice.
+
+**Root Cause** (manager_server.py:876-919):
+- `do_enable()` was parsing `version_spec` from `cnr_id` (e.g., `packagename@nightly`)
+- But it wasn't passing `version_spec` to `unified_enable()`
+- This caused `unified_enable()` to use default version selection (latest CNR)
+
+**Solution**:
+```python
+# Before (manager_server.py:876)
+res = core.unified_manager.unified_enable(node_name)  # Missing version_spec!
+
+# After (manager_server.py:876)
+res = core.unified_manager.unified_enable(node_name, version_spec)  # ✅ Fixed
+```
+
+**API Usage**:
+```python
+# Enable CNR version (default or latest)
+{"cnr_id": "ComfyUI_SigmoidOffsetScheduler"}
+
+# Enable specific CNR version
+{"cnr_id": "ComfyUI_SigmoidOffsetScheduler@1.0.1"}
+
+# Enable Nightly version
+{"cnr_id": "ComfyUI_SigmoidOffsetScheduler@nightly"}
+```
+
+**Version Selection Priority** (manager_core.py:get_inactive_pack):
+1. Explicit version in cnr_id (e.g., `@nightly`, `@1.0.1`)
+2. Latest CNR version (if available)
+3. Nightly version (if no CNR available)
+4. Unknown version (fallback)
+
+**Files Modified**:
+- `comfyui_manager/glob/manager_server.py` - Pass version_spec to unified_enable
+- `comfyui_manager/common/node_package.py` - Parse @version from disabled directory names
+- `comfyui_manager/glob/manager_core.py` - Fix is_disabled() early-return bug
+
+**Status**: ✅ Resolved - All 42 tests passing
+

+# Testing Guide for ComfyUI Manager
+
+## Code Update and Testing Workflow
+
+When you modify code that affects the API or data models, follow this **mandatory workflow** to ensure your changes are properly tested:
+
+### 1. OpenAPI Spec Modification
+
+If you change data being sent or received:
+
+```bash
+# Edit openapi.yaml
+vim openapi.yaml
+
+# Verify YAML syntax
+python3 -c "import yaml; yaml.safe_load(open('openapi.yaml'))"
+```
+
+### 2. Regenerate Data Models
+
+```bash
+# Generate Pydantic models from OpenAPI spec
+datamodel-codegen \
+  --use-subclass-enum \
+  --field-constraints \
+  --strict-types bytes \
+  --use-double-quotes \
+  --input openapi.yaml \
+  --output comfyui_manager/data_models/generated_models.py \
+  --output-model-type pydantic_v2.BaseModel
+
+# Verify Python syntax
+python3 -m py_compile comfyui_manager/data_models/generated_models.py
+
+# Format and lint
+ruff format comfyui_manager/data_models/generated_models.py
+ruff check comfyui_manager/data_models/generated_models.py --fix
+```
+
+### 3. Update Exports (if needed)
+
+```bash
+# Update __init__.py if new models were added
+vim comfyui_manager/data_models/__init__.py
+```
+
+### 4. **CRITICAL**: Reinstall Package
+
+⚠️ **You MUST reinstall the package before restarting the server!**
+
+```bash
+# Reinstall package in development mode
+uv pip install .
+```
+
+**Why this is critical**: The server loads modules from `site-packages`, not from your source directory. If you don't reinstall, the server will use old models and you'll see Pydantic errors.
+
+### 5. Restart ComfyUI Server
+
+```bash
+# Stop existing servers
+ps aux | grep "main.py" | grep -v grep | awk '{print $2}' | xargs -r kill
+sleep 3
+
+# Start new server
+cd tests/env
+python ComfyUI/main.py \
+  --enable-compress-response-body \
+  --enable-manager \
+  --front-end-root front \
+  > /tmp/comfyui-server.log 2>&1 &
+
+# Wait for server to be ready
+sleep 10
+grep -q "To see the GUI" /tmp/comfyui-server.log && echo "✓ Server ready" || echo "Waiting..."
+```
+
+### 6. Run Tests
+
+```bash
+# Run all queue task API tests
+python -m pytest tests/glob/test_queue_task_api.py -v
+
+# Run specific test
+python -m pytest tests/glob/test_queue_task_api.py::test_install_package_via_queue -v
+
+# Run with verbose output
+python -m pytest tests/glob/test_queue_task_api.py -v -s
+```
+
+### 7. Check Test Results and Logs
+
+```bash
+# View server logs for errors
+tail -100 /tmp/comfyui-server.log | grep -E "exception|error|failed"
+
+# Check for specific test task
+tail -100 /tmp/comfyui-server.log | grep "test_task_id"
+```
+
+## Complete Workflow Script
+
+Here's the complete workflow in a single script:
+
+```bash
+#!/bin/bash
+set -e
+
+echo "=== Step 1: Verify OpenAPI Spec ==="
+python3 -c "import yaml; yaml.safe_load(open('openapi.yaml'))"
+echo "✓ YAML valid"
+
+echo ""
+echo "=== Step 2: Regenerate Data Models ==="

+  --output-model-type pydantic_v2.BaseModel
+
+python3 -m py_compile comfyui_manager/data_models/generated_models.py
+ruff format comfyui_manager/data_models/generated_models.py
+ruff check comfyui_manager/data_models/generated_models.py --fix
+echo "✓ Models regenerated and formatted"
+
+echo ""
+echo "=== Step 3: Reinstall Package ==="
+uv pip install .
+echo "✓ Package reinstalled"
+
+echo ""
+echo "=== Step 4: Restart Server ==="
+ps aux | grep "main.py" | grep -v grep | awk '{print $2}' | xargs -r kill
+sleep 3
+
+cd tests/env
+python ComfyUI/main.py \
+  --enable-compress-response-body \
+  --enable-manager \
+  --front-end-root front \
+  > /tmp/comfyui-server.log 2>&1 &
+
+sleep 10
+grep -q "To see the GUI" /tmp/comfyui-server.log && echo "✓ Server ready" || echo "⚠ Server still starting..."
+cd ../..
+
+echo ""
+echo "=== Step 5: Run Tests ==="
+python -m pytest tests/glob/test_queue_task_api.py -v
+
+echo ""
+echo "=== Workflow Complete ==="
+```
+
+## Common Issues
+
+### Issue 1: Pydantic Validation Errors
+
+**Symptom**: `AttributeError: 'UpdateComfyUIParams' object has no attribute 'id'`
+
+**Cause**: Server is using old data models from site-packages
+
+**Solution**:
+```bash
+uv pip install .  # Reinstall package
+# Then restart server
+```
+
+### Issue 2: Server Using Old Code
+
+**Symptom**: Changes don't take effect even after editing files
+
+**Cause**: Server needs to be restarted to load new code
+
+**Solution**:
+```bash
+ps aux | grep "main.py" | grep -v grep | awk '{print $2}' | xargs -r kill
+# Then start server again
+```
+
+### Issue 3: Union Type Discrimination
+
+**Symptom**: Wrong params type selected in Union
+
+**Cause**: Pydantic matches Union types in order; types with all optional fields match everything
+
+**Solution**: Place specific types first, types with all optional fields last:
+```python
+# Good
+params: Union[
+    InstallPackParams,      # Has required fields
+    UpdatePackParams,       # Has required fields
+    UpdateComfyUIParams,    # All optional - place last
+    UpdateAllPacksParams,   # All optional - place last
+]
+
+# Bad
+params: Union[
+    UpdateComfyUIParams,    # All optional - matches everything!
+    InstallPackParams,      # Never reached
+]
+```
+

+
+## Adding New Tests
+
+When you add new tests or significantly modify existing ones, follow these steps to maintain optimal test performance.
+
+### 1. Write Your Test
+
+Create or modify test files in `tests/glob/`:
+
+```python
+# tests/glob/test_my_new_feature.py
+import pytest
+from tests.glob.conftest import *
+
+def test_my_new_feature(session, base_url):
+    """Test description."""
+    # Your test implementation
+    response = session.get(f"{base_url}/my/endpoint")
+    assert response.status_code == 200
+```
+
+### 2. Run Tests to Verify
+
+```bash
+# Quick verification with automated script
+./tests/run_automated_tests.sh
+
+# Or manually
+cd /mnt/teratera/git/comfyui-manager
+source ~/venv/bin/activate
+uv pip install .
+./tests/run_parallel_tests.sh
+```
+
+### 3. Check Load Balancing
+
+After tests complete, check the load balance variance in the report:
+
+```bash
+# Look for "Load Balancing Analysis" section in:
+cat .claude/livecontext/automated_test_*.md | grep -A 20 "Load Balance"
+```
+
+**Thresholds**:
+- ✅ **Excellent**: Variance < 1.2x (no action needed)
+- ⚠️ **Good**: Variance 1.2x - 2.0x (consider updating)
+- ❌ **Poor**: Variance > 2.0x (update required)
+
+### 4. Update Test Durations (If Needed)
+
+**When to update**:
+- Added 3+ new tests
+- Significantly modified test execution time
+- Load balance variance increased above 2.0x
+- Tests redistributed unevenly
+
+**How to update**:
+
+```bash
+# Run the duration update script (takes ~15-20 minutes)
+./tests/update_test_durations.sh
+
+# This will:
+# 1. Run all tests sequentially
+# 2. Measure each test's execution time
+# 3. Generate .test_durations file
+# 4. Enable pytest-split to optimize distribution
+```
+
+**Commit the results**:
+
+```bash
+git add .test_durations
+git commit -m "chore: update test duration data for optimal load balancing"
+```
+
+### 5. Verify Optimization
+
+Run tests again to verify improved load balancing:
+
+```bash
+./tests/run_automated_tests.sh
+# Check new variance in report - should be < 1.2x
+```
+
+### Example: Adding 5 New Tests
+
+```bash
+# 1. Write tests
+vim tests/glob/test_new_api_feature.py
+
+# 2. Run and check results
+./tests/run_automated_tests.sh
+# Output shows: "Load Balance: 2.3x variance (poor)"
+
+# 3. Update durations
+./tests/update_test_durations.sh
+# Wait ~15-20 minutes
+
+# 4. Commit duration data
+git add .test_durations
+git commit -m "chore: update test durations after adding 5 new API tests"
+
+# 5. Verify improvement
+./tests/run_automated_tests.sh
+# Output shows: "Load Balance: 1.08x variance (excellent)"
+```
+
+### Load Balancing Optimization Timeline
+
+| Tests Added | Action | Reason |
+|-------------|--------|--------|
+| 1-2 tests | No update needed | Minimal impact on distribution |
+| 3-5 tests | Consider updating | May cause slight imbalance |
+| 6+ tests | **Update required** | Significant distribution changes |
+| Major refactor | **Update required** | Test times may have changed |
+
+### Current Status (2025-11-06)
+
+```
+Total Tests: 54
+Execution Time: ~140-160s (2.3-2.7 minutes)
+Load Balance: 1.2x variance (excellent)
+Speedup: 9x+ vs sequential
+Parallel Efficiency: >90%
+Pass Rate: 100%
+```
+
+**Recent Updates**:
+- **P1 Implementation Complete**: Added 5 new complex scenario tests
+  - Phase 3.1: Disable CNR when Nightly disabled
+  - Phase 5.1: Install CNR when Nightly enabled (automatic version switch)
+  - Phase 5.2: Install Nightly when CNR enabled (automatic version switch)
+  - Phase 5.3: Install new version when both disabled
+  - Phase 6: Uninstall removes all versions
+
+**Recent Fixes** (2025-11-06):
+- Fixed `test_case_sensitivity_full_workflow` - migrated to queue API
+- Fixed `test_enable_package` - added pre-test cleanup
+- Increased timeouts for parallel execution reliability
+- Enhanced fixture cleanup with filesystem sync delays
+
+**No duration update needed** - test distribution remains optimal after fixes.

+
+## API Usage Patterns
+
+### Correct Queue API Usage
+
+**Install Package**:
+```python
+# Queue install task
+response = api_client.queue_task(
+    kind="install",
+    ui_id="unique_test_id",
+    params={
+        "id": "ComfyUI_PackageName",  # Original case
+        "version": "1.0.2",
+        "selected_version": "latest"
+    }
+)
+assert response.status_code == 200
+
+# Start queue
+response = api_client.start_queue()
+assert response.status_code in [200, 201]
+
+# Wait for completion
+time.sleep(10)
+```
+
+**Switch to Nightly**:
+```python
+# Queue install with version=nightly
+response = api_client.queue_task(
+    kind="install",
+    ui_id="unique_test_id",
+    params={
+        "id": "ComfyUI_PackageName",
+        "version": "nightly",
+        "selected_version": "nightly"
+    }
+)
+```
+
+**Uninstall Package**:
+```python
+response = api_client.queue_task(
+    kind="uninstall",
+    ui_id="unique_test_id",
+    params={
+        "node_name": "ComfyUI_PackageName"  # Can use lowercase
+    }
+)
+```
+
+**Enable/Disable Package**:
+```python
+# Enable
+response = api_client.queue_task(
+    kind="enable",
+    ui_id="unique_test_id",
+    params={
+        "cnr_id": "comfyui_packagename"  # Lowercase
+    }
+)
+
+# Disable
+response = api_client.queue_task(
+    kind="disable",
+    ui_id="unique_test_id",
+    params={
+        "node_name": "ComfyUI_PackageName"
+    }
+)
+```
+
+### Common Pitfalls
+
+❌ **Don't use non-existent endpoints**:
+```python
+# WRONG - This endpoint doesn't exist!
+url = f"{server_url}/customnode/install"
+requests.post(url, json={"id": "PackageName"})
+```
+
+✅ **Always use the queue API**:
+```python
+# CORRECT
+api_client.queue_task(kind="install", ...)
+api_client.start_queue()
+```
+
+❌ **Don't use short timeouts in parallel tests**:
+```python
+time.sleep(5)  # Too short for parallel execution
+```
+
+✅ **Use adequate timeouts**:
+```python
+time.sleep(20-30)  # Better for parallel execution
+```
+
+### Test Fixture Best Practices
+
+**Always cleanup before AND after tests**:
+```python
+@pytest.fixture
+def my_fixture(custom_nodes_path):
+    def _cleanup():
+        # Remove test artifacts
+        if package_path.exists():
+            shutil.rmtree(package_path)
+        time.sleep(0.5)  # Filesystem sync
+
+    # Cleanup BEFORE test
+    _cleanup()
+
+    # Setup test state
+    # ...
+
+    yield
+
+    # Cleanup AFTER test
+    _cleanup()
+```
