• Complete the primary user flow end-to-end
• Verify in-app purchases / subscriptions work in production

T+1 Hour

T+4 Hours

Mid-day assessment:

Decision Framework

Green Light (Proceed with Rollout)

All of these must be true:

• Crash-free rate > 99.5%
• ANR rate < 0.5% (Android)
• No critical bugs in core user flow
• Store rating ≥ 4.0 (if enough reviews to judge)
• Backend services healthy

Action: Increase Android rollout percentage. Maintain iOS release.

Yellow Light (Proceed with Caution)

Any of these are true:

• Crash-free rate between 99.0% and 99.5%
• Non-critical bugs reported but core flow works
• Store rating between 3.5 and 4.0
• Backend services showing elevated latency

Action: Hold rollout percentage. Investigate issues. Prepare hotfix if needed. Increase monitoring frequency.

Red Light (Halt Rollout)

Any of these are true:

• Crash-free rate below 99.0%
• Critical bug in core user flow (login, purchase, primary feature)
• Data loss or security issue
• Backend services down or severely degraded

Action: Halt Android staged rollout immediately. Prepare emergency hotfix. For iOS, submit hotfix with expedited review request. Communicate with affected users.
