Day-One Patch

Every shipped game has a day-one patch. Planning it before launch day prevents chaos. This skill scopes the patch to only what is safe and necessary, gates it through a lightweight QA pass, and ensures a rollback plan exists before anything ships. It is a mini-sprint — not a hotfix, not a full sprint.

When to run:

• After the gold master build is locked (cert approved or launch candidate tagged)
• When known bugs exist that are too risky to address in the gold master
• When cert feedback requires minor fixes post-submission
• When a pre-launch playtest surfaces must-fix issues after the release gate passed

Day-one patch scope rules:

• Only P1/P2 bugs that are SAFE to fix quickly
• No new features — this is fix-only
• No refactoring — minimum viable change
• Any fix that requires more than 4 hours of dev time belongs in patch 1.1, not day-one
