# Execution Log: Phase 2 (Parsing Benchmark)

**Date:** 2026-05-13

## Tasks Executed
- [x] Main Script (System Monitoring): Added `psutil` logic to capture `Peak RAM (MB)` (by reading memory RSS before and after the parse operation and taking the max) and `Peak CPU (%)` via `cpu_percent(interval=None)`. Required installing `psutil`, `pymupdf` (for `fitz`) into the virtual environment.
- [x] Main Script (Parsing Logic & Strict Constraint): Added `fitz.open()` to retrieve total pages securely. Instantiated `HybridParser()` and called `parser.parse_pdf(file)`. Populated OCR-related metrics with "N/A" as required, adhering strictly to the constraint of not modifying any file inside the `app/` directory.
- [x] Main Script (Output Handling): Created logic to dump the retrieved raw Markdown text into `Output-Parsing/{sanitized_name}_parsed.md`.
- [x] Main Script (Error Handling): Wrapped `parser.parse_pdf` in a `try...except Exception as e` block. On exception, it invokes `append_to_error_log` and updates the status to "❌ Failed", maintaining the robustness of the script so it continues gracefully.

## Activity Details
- Modified `scripts/Testing-Pipeline/benchmark_parsing.py` to include system monitoring logic using `psutil`.
- Handled path issues by inserting the project root into `sys.path` to allow imports from `app.services.parser.hybrid_parser`.
- Used `psutil.Process().oneshot()` techniques learned from Context7 to query memory and CPU data accurately.
- Installed missing dependencies (`psutil` and `pymupdf`) to the local virtual environment (`./venv/bin/pip install ...`) because the system enforces PEP 668 (externally-managed-environment).
- Executed strict compliance: The `HybridParser` file inside `app/` remains completely untouched.

## Status
Phase 2 tasks completed successfully. The core script logic is built and robust. Awaiting clearance to proceed with Phase 3 (Testing).
