Clicking a graph node now opens a detailed inspector instead of just name/type/file.

Rebased onto latest main (theme catalog). Inspector no longer repeats role chips as facts, drops a redundant App row when it matches the bounded context, and has a close control so the overlay does not trap the graph.

What you get

  • A short purpose for that node type (view, serializer, field, route, Zod schema, …)
  • Role chips when it is a sink or a contract
  • Typed extras already on the node: field type, permissions, bases, schema fields, URL, broker, etc.
  • Inputs and Outputs: neighboring nodes plus the edge that connects them (inferred stitches are labeled)

Tests

  • Unit coverage for purpose, extra formatting, neighbor lists, role/fact dedupe, and overflow CSS
  • E2E asserts the inspector shows purpose plus Inputs/Outputs sections

Summary by CodeRabbit

  • New Features

    • Added a node inspector to 2D and 3D graph views.
    • View node purpose, role, metadata, facts, location, and linked inputs and outputs.
    • See inferred relationships, item counts, and indicators when lists are truncated.
    • Dismiss the inspector with a close control or the Escape key.
  • Bug Fixes

    • Clearing a selection now consistently exits neighborhood-only mode.
  • UI Improvements

    • Improved inspector layout, scrolling, fact wrapping, and section styling.

📝 Walkthrough

Walkthrough

The graph UI now provides detailed node inspection in 2D and 3D views. Inspection includes roles, purposes, facts, locations, categorized links, inferred-link indicators, and truncation counts. Selection clearing, styling, tests, and bundled asset references were updated.

Changes

Node Inspector

Layer / File(s) Summary
Inspection data and classification
ui/src/nodeInspector.ts, ui/src/nodeInspector.test.ts
Added inspection contracts and utilities for node purposes, roles, metadata facts, graph links, inferred links, and bounded lists. Added unit coverage for these behaviors.
Graph view integration and selection
ui/src/ImpactGraph.tsx, tests/e2e/test_ui_flows.py
Replaced the basic inspector with detailed content in both graph views. Added Escape and button dismissal, shared selection clearing, and E2E assertions for purpose and input/output sections.
Inspector presentation and generated assets
ui/src/styles.css, ui/src/styles.test.ts, src/loadpath/static/index.html, src/loadpath/static/assets/*
Added inspector layout and content styles, style coverage for scrolling, wrapping, and close-control sizing, and updated bundled asset references.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to fa8ba

The richer node inspector improves graph exploration, but it currently repeats full graph scans during unrelated updates, which can add UI latency as graphs grow. The change is mergeable with explicit owner awareness and follow-up to avoid unnecessary recomputation.

The inspector now explains what the node is for, surfaces field types,
permissions, schema fields, and other extracted metadata, and lists
incoming/outgoing edges so a click shows the load path around that node.

Role chips (generated, inferred, mutation, …) were also listed as yes/no
facts, and App repeated the bounded context. Closing the panel lets you
click nodes the overlay was covering.

20-58: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Add a case for the list overflow suffix.

formatFact truncates arrays at 12 items and appends +N more. No test covers that branch. One extra case locks the displayed limit.

  it("truncates long list values", () => {

    expect(fact.value).toContain("+3 more");
  });

Consider moving the close button out of the role chip container.

The close button sits inside .inspector-roles, which uses flex-wrap: wrap. If a node carries several role chips, the chips wrap and the close button can shift to a second line. Placing the button as a direct child of .inspector-head keeps its position fixed.

Adding Escape to dismiss the inspector would also help keyboard users, since the panel is an overlay.

104-115: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Memoize inspectNode so it does not rescan the whole graph on every render.

GraphInspector receives the full nodes and edges arrays, not the visible subset. inspectNode builds a Map over all nodes and filters all edges twice. The component re-renders on each ImpactGraph state change, such as family toggles or detail changes, so the scan repeats even when the selected node did not change.

⚡ Proposed fix
-  const info = inspectNode(node, nodes, edges);
+  const info = useMemo(() => inspectNode(node, nodes, edges), [node, nodes, edges]);

useMemo is already imported in this file. Confirm the import list before applying.

Use one shared confidence threshold for inferred edges.

ui/src/ImpactGraph.tsx:89 and ui/src/nodeInspector.ts:297 both use 0.8. Extract this value into a shared named constant and use it for edge styling and the inferred flag.
