## Setup (3 tasks)

Initial configuration and environment preparation.

* [x] T001 \[S2605] Verify Sessions 01-04 prerequisites, read bridge endpoints, renderer exports, and current Session 05 stub scope (`.spec_system/PRD/phase_26/session_05_read_hook_route_shell_project_gallery.md`)
* [x] T002 \[S2605] Copy and size-check the upstream thinker hero asset under the AI OS media policy (`src/assets/hermes-art/knowledge-graph/thinker.webp`)
* [x] T003 \[S2605] Confirm TanStack route generation command behavior before adding the new route (`src/routeTree.gen.ts`)

***

## Foundation (6 tasks)

Core structures and base implementations.

* [x] T004 \[S2605] \[P] Create the typed Knowledge Graph read hook contract and query helpers with schema-validated response parsing and explicit error mapping (`src/hooks/use-knowledge-graph.ts`)
* [x] T005 \[S2605] Implement registry polling, active project selection, graph loading, and stale-selection reset with cleanup on scope exit for all acquired resources (`src/hooks/use-knowledge-graph.ts`)
* [x] T006 \[S2605] Implement bundled demo/seed fallback, offline state, empty state, parser-error state, god-node derivation, savings estimate, and Hermes status projection (`src/hooks/use-knowledge-graph.ts`)
* [x] T007 \[S2605] \[P] Create the thin `/knowledge-graph` route with head metadata and page adapter import (`src/routes/knowledge-graph.tsx`)
* [x] T008 \[S2605] \[P] Create the Knowledge Graph page adapter skeleton with stable responsive layout slots for hero, gallery, panel, and side rail (`src/components/knowledge-graph/knowledge-graph-page.tsx`)
* [x] T009 \[S2605] \[P] Add scoped KG hero CSS with reduced-motion-safe animation fallbacks (`src/styles.css`)

***

## Implementation (7 tasks)

Main feature implementation.

* [x] T010 \[S2605] \[P] Build the wired hero header using `thinker.webp`, live graph summary, provenance, and explicit loading, empty, error, and offline states (`src/components/knowledge-graph/knowledge-graph-hero.tsx`)
* [x] T011 \[S2605] \[P] Build the scrollable project gallery with keyboard-selectable project cards, active state, deterministic ordering, and accessible labels (`src/components/knowledge-graph/knowledge-graph-project-gallery.tsx`)
* [x] T012 \[S2605] \[P] Build the graph panel that mounts the Session 04 renderer with explicit loading, empty, error, offline, demo, and selected-node states (`src/components/knowledge-graph/knowledge-graph-panel.tsx`)
* [x] T013 \[S2605] \[P] Build the side rail for stats, confidence, important files, savings, provenance, Hermes status, and selected-node details with long-text overflow handling (`src/components/knowledge-graph/knowledge-graph-side-rail.tsx`)
* [x] T014 \[S2605] Wire `KnowledgeGraphPage` to `useKnowledgeGraph`, gallery selection, graph selected-node callbacks, and page-level fallback states with revalidation on route re-entry (`src/components/knowledge-graph/knowledge-graph-page.tsx`)
* [x] T015 \[S2605] Add the sidebar "Knowledge Graph" entry with `Waypoints`, active styling, and mobile-close behavior matching existing nav patterns (`src/components/app-sidebar.tsx`)
* [x] T016 \[S2605] Regenerate and verify TanStack route tree registration through normal tooling only, without manual generated-route edits (`src/routeTree.gen.ts`)

***

## Testing (4 tasks)

Verification and quality assurance.

* [x] T017 \[S2605] \[P] Write hook tests for loaded, empty, offline, fetch-error, malformed-payload fallback, selection reset, polling, and Hermes status projection (`src/hooks/__tests__/use-knowledge-graph.test.tsx`)
* [x] T018 \[S2605] \[P] Write page/component tests for hero, gallery selection, graph panel state shells, side rail selected-node details, and renderer mock callbacks (`src/components/knowledge-graph/__tests__/knowledge-graph-page.test.tsx`)
* [x] T019 \[S2605] Write route and route-tree tests covering `/knowledge-graph`, route head metadata, generated route registration, and sidebar navigation (`src/routes/__tests__/route-tree.test.ts`)
* [x] T020 \[S2605] Run focused tests, lint/type readiness checks, route generation verification, and ASCII validation for all Session 05 files (`.spec_system/specs/phase26-session05-read-hook-route-shell-project-gallery/tasks.md`)

***

## Completion Checklist

# 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-session05-read-hook-route-shell-project-gallery/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.
