alef 0.25.56

//! Verifies that the brew e2e codegen correctly:
//! 1. Renders mock_url_list arguments as multiple positional URL tokens.
//! 2. Uses the call's brew override function (e.g., "batch-scrape") as authoritative
//!    instead of tag-derived subcommand determination.
//!
//! This test validates batch-scrape and batch-crawl fixtures work correctly with
//! the brew CLI backend.
