      body: `Hey team,
  
  I’ve updated the architecture RFC for the multi-region state synchronization engine. Based on yesterday's benchmark results, we are proceeding with hybrid state-based CRDTs for deterministic document convergence.
  
  Key RFC Highlights:
  • P99 sync latency reduced from 140ms to 24ms across edge worker replicas
  • Deterministic Last-Write-Wins (LWW) resolver for metadata mutations
  • Offline reconciliation buffer with automated exponential retry backoff
  • Zero dependency footprint — pure TypeScript state machines
  
  Please review the attached technical specification and drop your comments before Thursday's design council.
  
  Best,
