summary
Shows how to make third‑party upgrades safe by isolating library usage and keeping tests green, specifically replace moment.js with date‑fns across a large app while preserving ~1000 tests. Explains creating a compatibility layer and using test doubles/seams so replacements run in production and tests run against stable fakes, reports actual refactor steps, the number of changed call sites, and demonstrates the replacement working end‑to‑end without breaking the suite.
