Research direction

The issue names the history service, incoming signals, and its worker, but no files, tests, or entry points. Start by locating the history service's signal intake and worker handling, then clarify how pausing should work and what worker state should resume acceptance; done requires an agreed behavior and tests for a worker that cannot keep up.
