## Lesson — Verify escaped characters in global renames

**Tags:** regex, testing, automation
**Scope:** packages/**/*.ts, packages/**/*.test.ts, packages/**/*.spec.ts

Standard sed substitutions often miss escaped characters in regex literals (e.g., @scope\/name); use multi-pass scripts to ensure test assertions remain valid after a package rename. Test files are in scope because they are the primary host for these escaped-regex literals — excluding them defeats the lesson's intent.
