Why traditional microservices fail under concurrent inventory contention, and how finite state machines with transactional outboxes guarantee exact-once execution.
KEY ARCHITECTURAL TAKEAWAYS:
Eliminating two-phase commit overhead with idempotent event logs
Local-first optimistic state transitions with guaranteed rollback safety
Benchmarking sub-15ms reconciliation across 100k distributed ledger mutations
