+# KinematicsPluginFactory Global State Issue
+
+## Summary
+
+Creating multiple `KinematicsPluginFactory` instances in the same process causes segmentation faults when the factories load different plugin types (e.g., KDL vs OPW). This issue affects Python bindings but originates in the C++ tesseract library.
+
+## Reproduction
+
+```python
+# Test 1: Create KDL-based kinematics (IIWA)
+factory1 = tesseract_kinematics.KinematicsPluginFactory(iiwa_plugins_yaml, locator1)
+inv_kin1 = factory1.createInvKin("manipulator", "KDLInvKinChainLMA", scene_graph1, state1)
+# Works fine
+
+# Test 2: Create OPW-based kinematics (ABB)
+factory2 = tesseract_kinematics.KinematicsPluginFactory(abb_plugins_yaml, locator2)
+inv_kin2 = factory2.createInvKin("manipulator", "OPWInvKin", scene_graph2, state2)
+# SEGFAULT here
+```
+
+## Error Messages
+
+```
+Warning: Failed to load symbol 'KDLFwdKinChainFactory'
+         at line 299 in kinematics_plugin_factory.cpp
+```
+
+or
+
+```
+Warning: Failed to create plugin instance 'OPWInvKinFactory' of type 'tesseract_kinematics::InvKinFactory'

+    - libtesseract_kinematics_opw_factory.dylib
+    ...
+         at line 356 in kinematics_plugin_factory.cpp
+```
+
+## Root Cause Analysis
+
+The `KinematicsPluginFactory` uses the `tesseract_common` plugin loading infrastructure which appears to use global state:
+
+1. First factory loads `tesseract_kinematics_kdl_factories` library
+2. Plugin symbols are registered in a global registry
+3. First factory is destroyed (Python GC, test teardown)
+4. Second factory tries to load `tesseract_kinematics_opw_factories`
+5. Global registry is in inconsistent state
+6. Symbol lookup fails or accesses freed memory → segfault
+
+The issue is in `tesseract_kinematics/core/src/kinematics_plugin_factory.cpp` around line 299-356.
+
+## Evidence
+
+- Tests pass when run **individually** in separate processes
+- Tests fail when run **together** in the same Python process
+- Using pytest `--forked` option causes `dlopen` handle issues (plugin libraries not found in forked child)
+- The error occurs at the boundary between different plugin library loads
+
+## Affected Code
+
+- `tesseract_kinematics/core/src/kinematics_plugin_factory.cpp`
+- `tesseract_common` plugin loading infrastructure
+- Any code that creates multiple `KinematicsPluginFactory` instances with different plugin configs
+
+## Potential Solutions
+
+### Option 1: Per-Factory Plugin State (Recommended)
+
+Make the plugin registry per-factory instead of global. Each factory maintains its own map of loaded plugins and dlopen handles.
+
+```cpp
+class KinematicsPluginFactory {
+private:
+    std::map<std::string, PluginHandle> loaded_plugins_;  // Per-instance
+    // Instead of global:
+    // static std::map<std::string, PluginHandle> loaded_plugins_;
+};
+```
+
+### Option 2: Reference-Counted Plugin Handles
+
+Keep track of how many factories reference each loaded plugin library. Only unload when reference count drops to zero.
+
+### Option 3: Never Unload Plugin Libraries
+
+Once loaded, keep plugin libraries loaded for process lifetime. Simplest fix but uses more memory.
+
+### Option 4: Clear Plugin Registry API
+
+Expose an API to explicitly clear/reset the plugin registry:
+
+```cpp
+// New API
+void KinematicsPluginFactory::clearGlobalRegistry();
+```
+
+Python users would call this between tests or when switching between different robot configurations.
+
+## Current Workaround
+
+Run tests in separate process invocations:
+
+```bash
+# Instead of:
+pytest tests/
+
+# Use:
+pytest tests/test_kdl.py
+pytest tests/test_opw.py  # Separate process
+```
+
+Or use pytest's `subprocess` isolation for affected tests.
+
+## Impact
+
+This issue affects:
+- Python bindings (segfaults)
+- C++ applications creating multiple factories
+- Unit testing any code using KinematicsPluginFactory
+- Applications switching between robot configurations at runtime
+
+## Related Files

+- `tesseract_kinematics/core/src/kinematics_plugin_factory.cpp`
+- `tesseract_common/include/tesseract_common/plugin_loader.h`
+- `tesseract_common/src/plugin_loader.cpp`
+
+## Test Case for C++
+
+```cpp
+#include <tesseract_kinematics/core/kinematics_plugin_factory.h>
+
+TEST(KinematicsPluginFactory, MultipleFactories) {
+    // Create first factory with KDL plugins
+    auto factory1 = std::make_shared<KinematicsPluginFactory>(iiwa_config, locator);
+    auto kin1 = factory1->createInvKin(...);
+    ASSERT_NE(kin1, nullptr);
+
+    // Destroy first factory
+    factory1.reset();
+
+    // Create second factory with OPW plugins
+    auto factory2 = std::make_shared<KinematicsPluginFactory>(abb_config, locator);
+    auto kin2 = factory2->createInvKin(...);  // Should not crash

+# nanobind Binding Issues for tesseract_python
+
+Report on issues encountered porting tesseract_pybind to nanobind.
+
+## 1. Reference Leaks in Poly Types
+
+**Severity**: High - Causes warnings at interpreter exit, potential memory corruption
+
+**Symptoms**:
+```
+nanobind: leaked 48 types!
+ - leaked type "WaypointPoly"
+ - leaked type "InstructionPoly"
+ ...
+nanobind: leaked 156 functions!
+ - leaked function "setManipulatorInfo"
+ - leaked function "getWaypoint"
+ ...
+```
+
+**Root Cause**: Type-erased `*Poly` wrappers store function pointers in global registries. These functions implicitly depend on module namespace, creating reference cycles that Python's GC cannot break.
+
+**Affected Types**:
+- `WaypointPoly`, `CartesianWaypointPoly`, `JointWaypointPoly`, `StateWaypointPoly`
+- `InstructionPoly`, `MoveInstructionPoly`
+- `CompositeInstruction` (iterates over InstructionPoly)
+
+**Fix Required**: Implement `tp_traverse` and `tp_clear` for cyclic GC support:
+
+```cpp
+// Example for WaypointPoly
+int waypointpoly_traverse(PyObject* self, visitproc visit, void* arg) {
+    // Visit all Python object references held by this type
+    return 0;
+}
+
+int waypointpoly_clear(PyObject* self) {
+    // Clear member variables that form cycles
+    return 0;
+}
+
+nb::class_<tp::WaypointPoly>(m, "WaypointPoly",
+    nb::type_slots({
+        {Py_tp_traverse, (void*)waypointpoly_traverse},
+        {Py_tp_clear, (void*)waypointpoly_clear}
+    }))
+    ...
+```
+
+**Reference**: https://nanobind.readthedocs.io/en/latest/refleaks.html
+
+---
+
+## 2. TaskComposer Async Execution Crash
+
+**Severity**: Critical - Segfaults during planning
+
+**Symptoms**: Crash at `future.wait()` after `executor.run(task, task_data)`
+
+**Context**:
+- `TaskComposerExecutor.run()` returns `std::unique_ptr<TaskComposerFuture>` (abstract base)
+- Actual returned type is `TaskflowTaskComposerFuture` (derived class)
+- nanobind needs both classes bound with proper inheritance for polymorphism
+
+**Current Workaround**: Tests marked `@pytest.mark.skip`
+
+**Attempted Fixes**:
+1. Added `TaskflowTaskComposerFuture` binding with inheritance
+2. Added `gil_scoped_release` during `wait()`
+3. Both base and derived classes re-expose methods
+
+**pybind11 Solution** (from tesseract_pybind):
+- Uses trampoline class `PyTaskComposerFuture` for abstract base
+- Explicit `std::unique_ptr<T>` holder type in class binding
+- Both base and derived need the unique_ptr holder
+
+**nanobind Equivalent Required**:
+```cpp
+struct PyTaskComposerFuture : tp::TaskComposerFuture {
+    NB_TRAMPOLINE(tp::TaskComposerFuture, 7);
+    void clear() override { NB_OVERRIDE_PURE(clear); }
+    bool valid() const override { NB_OVERRIDE_PURE(valid); }
+    bool ready() const override { NB_OVERRIDE_PURE(ready); }
+    void wait() const override { NB_OVERRIDE_PURE(wait); }
+    ...
+};
+
+nb::class_<tp::TaskComposerFuture, PyTaskComposerFuture>(m, "TaskComposerFuture")
+    ...
+```
+
+---
+
+## 3. OPW Kinematics Plugin Loading Under pytest
+
+**Severity**: Medium - Tests fail when using OPW-based robots
+
+**Symptoms**:
+```
+Failed to create plugin instance 'OPWInvKinFactory'
+Warning: This process is multi-threaded, use of fork() may lead to deadlocks
+```
+
+**Context**:
+- OPW plugin loads fine in standalone Python scripts
+- Fails when run under pytest due to fork/threading issues
+- `boost::plugin_loader` uses thread-local caches that corrupt during fork
+
+**Workaround Applied**: Use IIWA robot (KDL kinematics) instead of ABB IRB2400 (OPW) in tests
+
+**Root Cause**: pytest's forking combined with boost::dll plugin loader's global state causes corruption. The plugin factory maintains thread-local caches that don't survive fork correctly.
+
+**Long-term Fix Options**:
+1. Run tests with `--forked` to isolate each test
+2. Use threading-safe initialization in plugin loaders
+3. Disable fork in pytest configuration
+
+---
+
+## 4. FilesystemPath Type Mismatch
+
+**Severity**: Low - Fixed
+
+**Symptoms**:
+```
+TypeError: __init__(): incompatible function arguments
+```
+
+**Root Cause**: SWIG compatibility wrapper defined FilesystemPath as Python `str` subclass. nanobind's strict type checking rejected this.
+
+**Fix Applied**: Removed str subclass wrapper, use C++ binding directly:
+```python
+# Before (SWIG compatibility)
+class FilesystemPath(str):
+    def __new__(cls, s): return str.__new__(cls, str(s))
+
+# After (nanobind)
+from tesseract_robotics.tesseract_common._tesseract_common import FilesystemPath
+```
+
+---
+
+## 5. Cross-Module Type Inheritance
+
+**Severity**: Low - Workaround applied
+
+**Issue**: Types bound in different modules cannot directly inherit. For example, `TaskComposerPluginFactory` constructor takes `ResourceLocator` from tesseract_common module.
+
+**Workaround**: Manual type checking with `nb::handle`:
+```cpp
+m.def("__init__", [](Factory* self, const std::string& config, nb::handle locator_handle) {
+    auto common_module = nb::module_::import_("tesseract_robotics.tesseract_common._tesseract_common");
+    auto grl_type = common_module.attr("GeneralResourceLocator");
+    if (!nb::isinstance(locator_handle, grl_type)) {
+        throw nb::type_error("locator must be a GeneralResourceLocator");
+    }
+    auto* locator = nb::cast<tc::GeneralResourceLocator*>(locator_handle);
+    new (self) Factory(config, *locator);
+});
+```

+## Test Status Summary
+
+| Module | Tests | Status |
+|--------|-------|--------|
+| tesseract_common | 20+ | PASS |
+| tesseract_collision | 10+ | PASS |
+| tesseract_geometry | 10+ | PASS |
+| tesseract_environment | 15+ | PASS |
+| tesseract_kinematics | 10+ | PASS (KDL only) |
+| tesseract_command_language | 20+ | PASS |
+| tesseract_task_composer | 2 | SKIP (async crash) |
+| planning API | 35 | PASS (1 skip) |
+
+**Known Limitations**:
+- OPW kinematics tests require `--forked` or manual execution
+- TaskComposer pipeline tests crash (need trampoline fix)
+- Leaked types/functions warnings at exit (cosmetic, not functional)
