miner", + "notes": "A general high/critical vulnerability miner for the sn60__bitsec/miner lane. Ranks the project's own source across Solidity, Vyper, Rust, Move and Cairo; a triage pass that also picks audit targets, then deep and grouped source audits over the ranked files, and a second pass that sharpens candidate mechanisms. Falls back to two textbook model-free checks (unprotected initializer, tx.origin authorization) when no model finding survives. Findings localized to exact file and function. No project-specific or benchmark-specific content." +}
