Package cosmosbatch provides a state.Store implementation that wraps the in-memory store and mirrors Azure Cosmos DB's transactional-batch semantics: if any delete operation in a Multi targets a key that does not exist, the whole batch is rejected with a generic "transaction failed" error and none of the operations are applied.

Package fault provides a state.Store implementation that wraps the in-memory store and lets tests deterministically inject transient transactional save failures keyed by a substring of the operation key.

Package progress draws a live progress line for an integration test run.

Package schedulerplacement tests actor placement served by the scheduler.

Package statefulhistory contains integration tests for the stateful-history (delta) work-item optimization, where a worker that advertises WORKER_CAPABILITY_STATEFUL_HISTORY retains an instance's committed history between turns so the sidecar sends only the new events.
