# Execution Log: Phase 1 (Parsing Benchmark)

**Date:** 2026-05-13

## Tasks Executed
- [x] Setup Direktori: Added `ensure_dirs()` logic to create nested output, error log, and perform matrix folders.
- [x] Helper Functions (Sanitasi nama file): Added `sanitize_filename()` logic using regex to replace special characters with underscores.
- [x] Helper Functions (Append Matriks): Added `append_to_matrix()` logic that checks for existing file to add header, and appends formatted row properly.
- [x] Helper Functions (Append Error Log): Added `append_to_error_log()` logic to capture timestamp, error type, and full traceback via `traceback.format_exc()`.

## Activity Details
- Initialized script `scripts/Testing-Pipeline/benchmark_parsing.py`.
- Verified execution paths relative to `backend-sre` root directory.
- Mapped outputs correctly according to the strict Artifact Plan constraints.
- Utilized MCP Context7 to ensure library syntax was up-to-date (Specifically retrieved `psutil` documentation for Phase 2 preparation, though only standard library imports `os`, `re`, `traceback`, `datetime` were utilized in Phase 1 setup).

## Status
Phase 1 tasks completed successfully and are ready for architecture validation before moving onto Phase 2 (Main Script, System Monitoring, Parsing Logic).
