# [Template] PR Description

Add memory analysis report for Tizen HAL tensor filters

This PR introduces a comprehensive memory analysis report for the
Tizen HAL tensor filter implementations and their caller
infrastructure. The report details 6 identified memory-related issues,
including a confirmed constructor exception memory leak validated
with Valgrind. It provides risk assessments and recommendations for
immediate and long-term fixes to improve memory safety.

**Changes proposed in this PR:**
- New file `tizen_hal_memory_analysis_report.md` added.
- Report covers static analysis of `/ext/nnstreamer/tensor_filter/tizen_hal_*`
  and `gst/nnstreamer` codebases.
- Identifies 6 memory issues (leaks, double-free, uninitialized access).
- Includes Valgrind validation for a constructor exception memory leak.
- Provides risk assessment and recommendations for fixes.
