  • Website navigation crawling with configurable selectors (basic implementation).
  • Recursive sub-menu traversal.
  • Extraction of page name, URL, and last updated date (if available).
  • Markdown output generation in a tree structure (<website_name>_nav_map.md).
• Concurrency & Robustness:

  • Comprehensive logging (INFO, WARNING, ERROR) to console and structured JSON file (dlq.log).
  • Graceful handling of Network, Parsing, I/O, and Concurrency errors.
  • Thread-specific metadata in logs.
• User Experience:
  • tqdm progress bar during the crawling phase.
• Project Setup & Documentation:
  • Standard Python project structure (src/, tests/, input_csvs/, output_maps/, logs/).
  • requirements.txt for dependency management.
  • .gitignore and .clineignore files.
  • Initial unit tests (pytest) for utilities, CSV processing, and crawler functions.
  • Comprehensive Memory Bank documentation in dev_docs/ (project_brief.md, codebase_summary.md, tech_stack.md, current_task.md, project_tracker.md, implementation_plan.md).
  • README.md with project overview, setup, and usage instructions.
  • CHANGELOG.md following Keep a Changelog format.
