What problem does it solve? Redux-saga applications need consistent rules for starting, stopping, and restarting sagas, plus safe handling of crash reports, without leaking package-internal saga-manager APIs into application code. ## Core Features & Use Cases - Lifecycle guidance: Explains how store.runSaga starts sagas, how returned cancel functions and reference counting stop them, and when Store.dispose applies. - Crash report semantics: Documents addCrash/clearCrashes behavior, serialized crash report shape, per-saga retention with MAX_SAGA_CRASH_REPORTS, and omittedCount trimming. - Restart backoff rules: Details getBackOffDelay exponential backoff from 1s up to a 10-minute cap with restart-pressure decay after stable runtime. - Use Case: An agent editing saga-manager docs or code uses this checklist to keep import boundaries intact and avoid documenting internal APIs like @internal_sagaManager as public. ## Quick Start Ask the agent to explain or verify how saga crashes, restarts, and backoff work in the themis Store before editing any saga-manager guidance.
