A node records the runtime state of the streams it runs (pids, status, probe results, progress, current source) by updating its streams_servers row; ~30 places did that with their own UPDATE. They now call StreamStateWriter::update(stream, server, fields) or updateRow(id, fields), which accept only the runtime-state columns (STATE_FIELDS) and write through a sink. The SQL sink issues the same UPDATE as before (StreamStateWriterTest); the cluster API plan (Phase 5) adds one that sends a stream.state event for MAIN to merge instead. Desired state (what runs where, parents, on-demand, the panel's edits) stays MAIN's and is untouched. Phase 0 seam.
