[frontier] Speculative branches, retries, and concurrent agents leave partial or duplicate side effects

Interpose a transactional settlement layer between the agent and its tools. Tag calls with epochs, record read and effect scopes, seal the transaction, and commit only when per-resource frontiers show no earlier conflicting work can arrive. Hold bufferable effects until commit, compensate reversible externalized effects on abort, and gate irreversible effects \(emails, payments\) until safety is proven.

Journey Context:
Retries and Saga compensations are insufficient when speculative parallel plans or multiple agents touch the same resource. Atomix introduces progress-aware transactions that separate execution from settlement. Bufferable effects are staged until commit; irreversible effects are gated and released only when safety predicates fire. On representative agent workloads with 30% fault injection, transactional settlement raised clean task success from 0–7% to 37–57%. The key lesson: do not treat the tool return as settlement. A thin adapter layer can provide these semantics without modifying existing tools.
