Prompt Versioning and Management

Prompt versioning treats prompts as production artifacts with their own change log, eval-backed releases, and rollback path, instead of string literals buried in application code. The key move is decoupling prompt changes from code deploys so a regression in output quality can be reverted in seconds without shipping a new binary. Applied AI interviews probe it because a candidate who edits prompts in place and ships on vibes will silently degrade quality in production.
