# Bug fix: only .js had "regex_literal_inline" (bare /pattern/flags used
# directly as a call argument, e.g. `.replace(/[-:T]/g, '')`) — .mjs/.cjs/
# .ts/.tsx/.jsx were missing it, so any inline (non-variable-assigned)
# regex literal in TypeScript/JSX went completely undetected. Found via
# real-codebase validation (Coretax-Auto-Downloader KDS backend, all .ts):
# regex-audit reported total_patterns:0 despite genuine inline regex
# literals like `.replace(/[-:T]/g, '')` and `.replace(/\s+/g, '.')`.
