   needed; composition through plugins is (plugin set fixed at deploy). Research in `research/chord-on-durable-objects.md`.
 - Deferred until a concrete case: jobs as objects and where a flow lives (when login is ported); project plugins.
+- **Every object may contribute** (owner, 2026-10-29: "note it down as something to consider for the future; can be
