Deployment readiness is a habit. Version control, build routines, test passes, analytics, patch notes, rollback thinking, and communication rhythms should exist before public pressure arrives.
Milestones as release rehearsals
Each milestone should answer a production question. Does the loop work? Is the interface readable? Can the build be deployed safely? Do players understand the next action? This turns development into an operational system.
Deploy without panic
A calm launch is not luck. It is the result of repeatable systems and the willingness to test them before they matter publicly.
