+### `scripts/mosaic` sends these verbs to the wrong CLI

+Added 2026-10-19 after Darkwing's row 169 rehearsal. `scripts/mosaic:37-39` sends only `usage`, `project`,
+`limits`, `inbox`, `decide`, `tasks`, `agents`, `trail`, `talk`, `stop`, `launches` and `bus` to
+`packages/cli/src/cli.mjs`. Everything else falls through to the seat CLI, which prints `usage: mosaic launch ...`.
+That includes `plugins`, `name`, `names`, `follow`, `threads` and `thread`, though `cli.mjs:571-581` handles them
+all. So `mosaic plugins set` (W1), `mosaic name` (W4) and `mosaic names` fail through the wrapper, while
+`packages/plugins/README.md:52-53` and `packages/webui/README.md:645` document them. Add those six verbs to that
+case line. `queue` and `business` keep their own branches.
