[architecture] Partial failure in multi-agent transaction leaving system in inconsistent state with no rollback mechanism

Implement Saga orchestration with explicit compensating transactions for each agent action; on failure, run compensations in reverse order to restore consistency without holding distributed locks.

Journey Context:
ACID transactions across distributed agents require two-phase commit which blocks on network partitions, killing availability and adding latency. The Saga pattern accepts eventual consistency and handles failures via compensating logic. For example, if Agent B charged a credit card, the compensation issues a refund. This avoids long-lived locks and allows agents to remain autonomous. The tradeoff is the complexity of writing compensations for every action, and temporary inconsistency windows where users might see phantom charges before compensation runs. It also requires idempotency on compensations to handle retry scenarios safely.

environment: Long-running business processes spanning multiple autonomous agents with irreversible side effects such as payments or inventory reservation. · tags: saga distributed-transactions compensation consistency orchestration · source: swarm · provenance: https://microservices.io/patterns/data/saga.html
