* [x] T008 \[S2604] Implement adjacency and active highlight helpers for hover and pinned state with types matching declared contract and exhaustive enum handling (`src/components/knowledge-graph/knowledge-graph-3d.tsx`)

***

## Implementation (7 tasks)

Main feature implementation.

* [x] T015 \[S2604] Implement Full/Core toggle, Pause/Play, capped-node notice, and legend with platform-appropriate accessibility labels, focus management, and input support (`src/components/knowledge-graph/knowledge-graph-3d.tsx`)

***

## Testing (4 tasks)

Verification and quality assurance.

* [x] T016 \[S2604] \[P] Write loader tests for status text, stable shell rendering, and reduced-motion-safe output (`src/components/knowledge-graph/__tests__/knowledge-graph-loader.test.tsx`)
* [x] T017 \[S2604] \[P] Write renderer tests with mocked vendor modules for loading, projection, density, capping, callbacks, and cleanup (`src/components/knowledge-graph/__tests__/knowledge-graph-3d.test.tsx`)
* [x] T018 \[S2604] Run targeted component tests, typecheck affected files, and verify no top-level 3D vendor imports (`package.json`)
* [x] T019 \[S2604] Validate ASCII encoding and update implementation notes with manual verification results (`.spec_system/specs/phase26-session04-reusable-3d-code-graph-renderer/implementation-notes.md`)

***

## Completion Checklist

Before marking session complete:

* [x] All tasks marked `[x]`
* [x] All tests passing
* [x] All files ASCII-encoded
* [x] implementation-notes.md updated
* [x] Ready for the validate workflow step

***

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase26-session04-reusable-3d-code-graph-renderer/tasks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
