#!/usr/bin/env python3
"""
Verify that all Rust files in a crate meet file size limits.

Checks both GOAL (500 lines) and HARD LIMIT (1000 lines) by default.

Usage:
    python3 scripts/verify-file-size.py <crate-path> [--goal LINES] [--hard-limit LINES]

Example:
    python3 scripts/verify-file-size.py multi-llm
    python3 scripts/verify-file-size.py multi-llm --goal 500 --hard-limit 1000

Exit codes:
    0 - All files meet goal
    1 - Files exceed goal but meet hard limit
    2 - Files exceed hard limit (requires approval)
