106-114: Consider adding context manager support and resource managementTo maintain consistency with the Serializer class and ensure proper resource handling, consider adding:
- Context manager methods (enter, exit)
- Resource management methods (close, flush)
Example implementation:

Learning: In `src/clp_ffi_py/ir/native/PyDeserializer.cpp`, the `deserialize_log_event` method in the `PyDeserializer` class ensures proper loop termination and does not risk infinite loops, even when handling incomplete or corrupted streams.

Learning: In code interfacing with CPython (e.g., `src/clp_ffi_py/ir/native/PyDeserializer.cpp`), using raw pointers for memory management is acceptable due to CPython's memory management requirements.

Learning: In the `src/clp_ffi_py/ir/native` module, raw pointers with `gsl::owner` are intentionally used instead of `std::unique_ptr` to comply with CPython's memory management requirements.

262-270: LGTM! Well-implemented module initialization.
The implementation includes proper type safety checks and error handling.
122-124: 🛠️ Refactor suggestion
Add buffer capacity validation.
Consider adding validation for the buffer capacity to ensure it's within reasonable bounds:
Py_ssize_t buffer_capacity{PyDeserializer::cDefaultBufferCapacity};
int allow_incomplete_stream{0};
+ if (buffer_capacity <= 0 || buffer_capacity > PY_SSIZE_T_MAX / 2) {
+ PyErr_SetString(PyExc_ValueError, "buffer_capacity must be positive and within reasonable bounds");
+ return -1;
+ }Likely invalid or redundant comment.

Description
This PR adds a new class
Deserializerto support deserializing log events from CLP key-value pair IR stream. TheDeserializeris designed to read from a Python IO[byte] object as the input stream, and emitKeyValueLogEventinstances as the deserialized output.Validation performed
