RFC: Implement @ceoc-next handle for CEOC handover workflow

Request for comments

Need

The latest CEOC workflow requires Engineers to manually search for the next on-call person when needing to reach them before rotation schedules update. This creates delays during time-sensitive situations where quick handover or early coordination is needed.

Current pain points:

• Wait for @ceoc handle to update after rotation
• Manually search PagerDuty schedules or #spt_leaders-daily
• Time lost during emergency situations

Approach

Implement a @next-ceoc Slack handle that automatically points to the next scheduled CEOC engineer. The current @ceoc Engineer can use this to ping the next CEOC engineer in case something needs to be communicated in advance.

Implementation considerations:

• Integrate with existing PagerDuty schedule automation
• Update alongside current @ceoc handle rotation
• Consider fallback behavior if next engineer is unavailable

Benefit

• Eliminates manual lookup of schedules for handovers.
• Easier coordination during overlapping/multiple emergencies.
• Allowing earlier engagement allows for better handovers.

Competition / Alternatives

• Continue current @ceoc slack handle rotation and Pagerduty lookups.
