"""Example: Browsing and filtering the ZIRAN attack vector library.

Demonstrates how to explore the built-in library of 21+ attack
vectors, filter by category/phase/OWASP mapping, and load custom
attack vectors from your own YAML files.  No API keys required.

What this example shows
-----------------------
  1. Loading the built-in attack library
  2. Listing all categories and vector counts
  3. Filtering vectors by phase, category, severity, OWASP mapping
  4. Using the multi-criteria ``search()`` API
  5. Loading custom attack vectors from a YAML file

Usage::

    uv run python examples/attack_library_example.py
