+## `createMachineSessionWorkflowStatus(state)`
+
+This helper derives a lightweight status object for upper-level control pages:
+
+```js
+{
+  readiness: { ini: "...", interp: "...", opfs: "..." },
+  lastAction: "run-gcode",
+  error: null,
+  session: { snapshotLabel: "...", workflow: "...", gcode: "..." },
+  run: { status: "ok", canonicalEventCount: 2, motionSnapshotCount: 2, iniWasmPath: "..." }
+}
+```
+
+It is intended for polling or status panels that need current UI workflow
+state without parsing logs, DOM nodes, or transient window state.
