Fix impact graphs and add a layered 3D view for large graphs - #13
Conversation
📝 WalkthroughWalkthroughThe PR adds Django form and signal extraction, excludes test projects from Django detection, introduces linked-edge graph integrity and index revisions, and adds filterable 2D and 3D graph views with supporting tests. ChangesLoad-path extraction and graph visualization
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR changes graph extraction and makes large graphs open in a new 3D view. At the current head, graph results can still be incorrect when a test Django project is selected or a signal sender is passed positionally, while selecting nodes in large 3D graphs can reset the view and cause costly rebuilds; these issues should be fixed or explicitly accepted before merging.

Custom React Flow nodes had no handles, so the UI drew isolated boxes while reporting dozens of edges. Subgraphs could also keep dangling src/dst ids. Attach left/right handles, drop unlinked edges from review and HTML graphs, and assert the invariant in unit and Playwright tests. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Library repos such as Wagtail keep manage.py under a test project. Drafted loadpath.yml then indexed only that test tree's contexts. Prefer the common parent of non-test apps.py files so contrib apps like redirects show up as architecture contexts. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Kitsune form PRs and Wagtail custom signals produced isolated nodes because ModelForm classes and signal.connect(handler) were ignored. Index forms as django.form nodes, treat .connect() in apps.py as receives edges, and pick up undecorated handlers in signal_handlers.py. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Existing indexes skipped every unchanged file after INDEX_REVISION changed, so new form/signal extractors never landed. Force a full extract when the revision meta differs, and do not treat TestCase subclasses named TestFooForm as Django forms. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Large architecture graphs are shown as orbitable type-layers instead of one 2D hairball, with overview filters, family chips, and click-to-highlight neighbors. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
The Three.js chunk loads on demand; the graph-3d wrapper is now present as soon as 3D layers is selected, and the canvas fills the remaining pane. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Catch renderer creation failures instead of crashing the pane, and launch Playwright Chromium with SwiftShader so headless tests can still toggle 3D layers. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Orbiting the camera no longer swallows inspect clicks, and node spheres are slightly larger so they are easier to hit. Co-authored-by: Damon <Modsofthenation@users.noreply.github.com>
Keep the WebGL canvas on its own mount so hover tooltips do not reconcile against the renderer DOM, dispose layer geometries and the GL context on unmount, and only show family chips for stacks that are actually present. Rebuild the bundled UI so the static assets match. Co-authored-by: zord.lack.net <zord.lack.net@gmail.com>

Record a residual for an unresolvable signal handler.
Line 310 prevents _signal_connect from running when the handler is dynamic. The residual at Lines 971-973 is then unreachable for calls such as post_save.connect(lambda **kwargs: ...). Call _signal_connect for every signal-like connect() call. Let that method retain the residual when it cannot resolve a handler.

Django official documentation Signal.connect receiver sender positional arguments
💡 Result:
In Django, the Signal.connect method is used to register a receiver function to handle a specific signal [1][2]. The signature for the connect method is: Signal.connect(receiver, sender=None, weak=True, dispatch_uid=None) [1][3] Parameters: - receiver: The callable function or method that will be executed when the signal is sent [1]. - sender: (Optional) A specific sender to filter signals from. If provided, the receiver will only be called when the signal is sent by this specific sender [1][2]. - weak: (Optional) A boolean that defaults to True. If True, Django stores the receiver as a weak reference, which can cause the receiver to be garbage collected if it is a local function. Set to False to keep the reference alive [1][2]. - dispatch_uid: (Optional) A unique identifier to prevent duplicate signals if the same receiver is connected multiple times [1][3]. Regarding the receiver function itself, Django enforces that all signal receivers must accept a sender argument and wildcard keyword arguments (kwargs) [1][2]. Even if a signal is documented as sending no additional information, your receiver function must be defined to accept these arguments to remain compatible with future changes [1][3]: def my_receiver(sender, kwargs): # Your logic here pass Attempting to define a receiver that does not accept kwargs may result in a ValueError, as Django's dispatcher explicitly checks for this requirement [4]. While the sender argument is technically a positional argument in the receiver's definition, signals are dispatched such that these values are passed to the receiver correctly [1].

Handle positional sender arguments.
Django supports Signal.connect(receiver, sender). Read the second positional argument when sender= is absent. Otherwise, calls such as post_save.connect(sync_invoice, Invoice) omit the EMITS_SIGNAL edge.

🚀 Performance & Scalability | 🟠 Major | ⚡ Quick win
The scene rebuilds on every node selection, and the camera resets.
The effect depends on nodes and edges (Line 281). In ui/src/ImpactGraph.tsx lines 130-139, visible is memoized with selectedId in the dependency list, so visibleGraph returns new array identities on each click even when the content is unchanged. Each click therefore tears down and recreates the whole WebGL scene: geometries, materials, meshes, discs, labels, controls, and the camera position (lines 168-177). The user loses the current orbit and zoom, and large graphs (the PR reports up to 419 nodes) pay the full rebuild cost per click.
The paint effect at lines 283-285 already handles selection highlighting, so the rebuild is not needed for selection.
Derive a stable content key and depend on that instead.
♻️ Proposed fix
+ const graphKey = useMemo(
+ () => `${nodes.map((n) => n.id).join("|")}#${edges.map((e) => e.id).join("|")}`,
+ [nodes, edges],
+ );
+ const dataRef = useRef({ nodes, edges });
+ dataRef.current = { nodes, edges };
+
useEffect(() => {
const host = hostRef.current;
if (!host) return;
+ const { nodes, edges } = dataRef.current;- }, [nodes, edges]);
+ }, [graphKey]);Note that useMemo for visible in ui/src/ImpactGraph.tsx can also drop selectedId from its dependencies when neighborhoodOnly is false, which removes the churn at the source.
Also applies to: 281-281

The WebGL fallback text overlaps the 3D guidance hint.
.graph-3d-hint is absolutely positioned at left: 10px; bottom: 10px. Two elements use this class at the same time: the guidance paragraph in ui/src/ImpactGraph.tsx lines 257-260, and the fallback message in ui/src/LayeredGraph3D.tsx lines 291-293. If WebGL is unavailable, both render and the two texts draw on top of each other, so neither is readable.
Hide the guidance paragraph when the fallback is shown, or stack the messages in normal flow.

Place django.form in the labeled forms layer.
layerFor("django.form") returns layer 3. ui/src/graphView.ts Line 59 labels that layer as serializers. Line 69 reserves layer 13 for forms / tests. Map forms to layer 13 so the 3D label matches the rendered node type.

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
