Artifact: Risk Prioritization — Top Three This Sprint

Aurora Checkout Redesign -- risk prioritization -- exercises co-10.

Rank	Risk	Score	Rationale for this rank
1	Load test reveals checkout cannot sustain 3x traffic	15	Highest impact (5) of any risk -- a launch-blocking failure discovered late.
2	Key engineer (Bayu) on scheduled leave during Sprint 2	15	Tied on score; the leave date is fixed and near-term, so its mitigation window is the tightest of any risk on the list.
3	Apple Pay API breaking change before launch	12	Tied with the code-freeze risk at 12; ranked above it because a third-party API change is outside the team's control entirely, while the freeze date is knowable in advance with one confirming conversation.

Risks not in the top three (holiday code-freeze, scope-creep) remain on the register with their existing mitigations assigned, without dedicated attention this sprint.
