Conversation
- Implement `autoLayoutGraph` supporting Top-to-Bottom (TB) and Left-to-Right (LR) flow directions with topological rank propagation, cycle safety, and offset centering. - Add Auto-Layout controls (`⚡ layout TB` and `LR`) to the header toolbar in `Index.tsx` integrated with undo snapshotting. - Add Execution Metrics Summary Banner in the Execution Run Drawer displaying run duration, step count, unique node types, and pass/fail status badge. - Add comprehensive unit tests in `graphLayout.test.ts` and `globalsAndLogs.test.tsx`.

These tests duplicate metric calculations instead of rendering the
Indexbanner or calling the production metrics helper. A broken banner can therefore pass both tests. Add a component-level assertion for the displayed status, duration, step count, and node-kind count.The first fixture also has no
kind: "runtime"entry. Add one and verify thatuniqueKindsremains2; otherwise the runtime filter is untested.Also applies to: 247-261

- Around line 52-75: Update the rank computation around the existing queue-based
propagation to first identify and condense strongly connected components, then
propagate ranks only across the resulting acyclic component graph so cyclic
components receive stable ranks independent of unrelated nodes. Preserve
fallback handling for graphs without explicit entry points, and add a regression
test covering an entry node reaching a cycle alongside a disconnected node.
In `@frontend/src/pages/Index.tsx`:
- Around line 2256-2279: Update the Execution Metrics Summary banner rendering
near the runLogs condition so an active run is not displayed as “✓ PASSED”:
require running to be false before showing the completed-run banner, or render
an explicit in-progress status while running remains true; preserve the existing
FAILED/PASSED determination for completed runs.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Stop rank propagation through cyclic components.
Lines 52-75 increase ranks on every cycle traversal until maxPasses expires. A cycle reachable from an entry node can therefore receive different positions when an unrelated disconnected node is added, because that node increases maxPasses.
Condense strongly connected components before rank propagation. Assign ranks on the resulting acyclic component graph. Add a regression test for an entry node that reaches a cycle plus an unrelated node.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Do not mark an active run as passed.
onLog adds entries while running is still true. After the first successful step, this banner shows ✓ PASSED even when a later step can fail. Render this completed-run banner only when running is false, or show an in-progress status while execution continues.
