…pack first Closes #1072. audit_strict_coverage.py's missing_case_entirely list found 44 non-None LANGUAGE_DEFINITIONS keys with zero _SIMPLE_CASES coverage across 6 languages -- most notably python's and javascript's entire AI/ML extension pack (llm_api, llm_orchestrator, llm_vector_store, ml_traditional, dl_frameworks) had no detection test coverage at all, a real blind spot in a supply-chain-risk detection feature. Every candidate case was empirically verified with verify_candidates.py's check_case against the real compiled regex before being written in; no engine bugs surfaced (expected -- this suite proves presence/absence of a construct, not exact-identifier extraction, per how_to_harden_strict_signatures.md). python: 19 keys, javascript: 16, haskell: 4, objective-c: 3, solidity: 1, yaml: 1. Re-running audit_strict_coverage.py confirms missing_case_entirely is now empty for all six languages. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
