# Session Specification

**Session ID**: `phase26-session09-documentation-validation-release` **Phase**: 26 - Knowledge Graph Shared Brain Port **Status**: Not Started **Created**: 2026-06-09

***

## 1. Session Overview

This session closes Phase 26 by turning the implemented Knowledge Graph Shared Brain port into a documented, validated, and releasable product slice. Sessions 01 through 08 delivered the typed graph contracts, bundled seed fixtures, loopback-only read bridge, admin-gated ingest and removal bridge, reusable 3D renderer, `/knowledge-graph` route, ingest UI, connect prompt, starter chips, Hermes chat grounding, home surface, shared-brain scripts, and OAuth-provider readiness fix.

The remaining work is not new feature behavior. The session must reconcile the source contract with AI OS documentation, fold the upstream `GRAPHIFY.md`, `GRAPHIFY_HANDOVER.md`, `HANDOVER.md`, unlocks roadmap, and changelog intent into AI OS-native docs, run the release validation envelope, and record parity against the upstream `v2.4` Knowledge Graph and `V2.5` Shared Brain work.

The end state should let an operator or future maintainer understand the shared-brain model, one-command setup path, optional `graphify` dependency, route and endpoint contracts, admin-gated write boundary, Hermes grounded chat toolset, security posture, responsive behavior, residual gaps, and release version without reading the upstream tree.

***

## 2. Objectives

1. Create source-verified Knowledge Graph guide, handover, and unlock roadmap docs that describe shipped AI OS behavior.
2. Update data-contract, agent-page, and local API docs for `/knowledge-graph`, `/__graphify_*` wire paths, graph registry data, and grounded chat toolset.
3. Run and record the full validation envelope: tests, typechecks, lint, format check, build, responsive/e2e, accessibility, security, private artifact, and ASCII/LF checks.
4. Record parity sign-off against upstream `v2.4`/`V2.5`, reconcile release version metadata, and add the Phase 26 changelog entry.

***

## 3. Prerequisites

### Required Sessions

* [x] `phase26-session01-graph-data-contracts-seed-fixtures` - provides typed graph contracts, seed fixtures, and graph registry contract.
* [x] `phase26-session02-graph-read-bridge-registry-endpoints` - provides loopback-only read endpoints and path-confined graph reads.
* [x] `phase26-session03-graph-ingest-removal-admin-bridge` - provides admin-gated ingest and removal endpoints.
* [x] `phase26-session04-reusable-3d-code-graph-renderer` - provides the lazy reusable 3D code graph renderer.
* [x] `phase26-session05-read-hook-route-shell-project-gallery` - provides the `/knowledge-graph` route, hook, gallery, side rail, and wired hero.
* [x] `phase26-session06-ingest-ui-connect-prompt-starter-chips` - provides the ingest UI, connect prompt, and starter chips.
* [x] `phase26-session07-hermes-chat-grounding-graph-toolset` - provides grounded Hermes chat integration with the `graphify` toolset.
* [x] `phase26-session08-homepage-surface-shared-brain-scripts-oauth` - provides the home surface, Shared Brain scripts, dashboard ingest helper, and OAuth-provider readiness fix.

### Required Tools/Knowledge

* Bun 1.3.14 project toolchain.
* Existing package scripts in `package.json`.
* React 19, TypeScript 6, TanStack Router/Query, Vite 8, Vitest, and Playwright.
* Current Knowledge Graph source files: `src/lib/knowledge-graph-types.ts`, `src/lib/knowledge-graph-admin-types.ts`, `src/hooks/use-knowledge-graph.ts`, `src/hooks/use-knowledge-graph-admin.ts`, `src/components/knowledge-graph/`, `scripts/lib/knowledge-graph-dev-bridge.ts`, `scripts/lib/knowledge-graph-admin-bridge.ts`, `scripts/setup-graphify-brain.sh`, and `scripts/graph-to-dashboard.sh`.
* Upstream reference docs under `/home/aiwithapex/projects/claudeos/claude-os-v2.4/`.
* Existing documentation conventions: document what exists, validate commands and paths before documenting them, and avoid planned-as-implemented claims.

### Environment Requirements

* Work from the repository root.
* `graphify` is optional for automated validation; seed/demo fallback must remain documented and usable when the binary is absent.
* Any live ingest or removal smoke check must be opt-in, local-only, and avoid private repository disclosure in committed evidence.
* Generated private data, `.env*`, dashboard tokens, OAuth material, graph artifacts, Playwright traces, screenshots, local logs, and private paths remain out of git.

***

## 4. Scope

### In Scope (MVP)

* Operators can set up and use the Shared Brain - document the model, one-command setup, optional `graphify` install path, dashboard ingest helper, usage flow, fallback behavior, and cost note in `docs/knowledge-graph.md`.
* Maintainers can carry the feature forward - fold upstream handover detail into AI OS-native architecture notes, including route, hook, renderer, bridge, data directory, registry, and security boundaries.
* Future roadmap work is explicit - create the five-tier Knowledge Graph unlocks roadmap and mark it as forward-looking rather than shipped behavior.
* Maintainers can rely on contracts - update data-contract, agent-page, and local API docs for `/knowledge-graph`, `/__graphify_list`, `/__graphify_graph`, `/__graphify_admin_status`, `/__graphify_ingest`, `/__graphify_remove`, registry entries, seed/live provenance, and Hermes grounded chat toolset behavior.
* Security reviewers get current evidence - document loopback-only reads, token/admin/non-demo write gates, path confinement, argv-only process spawn, temp cleanup, oversized graph rejection, vendored-dependency guard, and token non-leakage.
* Release owners get evidence - record validation commands, responsive/e2e and accessibility review, parity sign-off, residual gaps, changelog entry, and release version bump.

### Out of Scope (Deferred)

* New Knowledge Graph product behavior - Reason: Sessions 01-08 completed the feature work; this session certifies it.
* New bridge endpoints or endpoint names - Reason: prompt and script compatibility depends on the current `/__graphify_*` wire paths.
* Changing the graph schema, registry schema, or Hermes chat admin model - Reason: the prior sessions already define the shipped contract.
* Making `graphify` a hard dependency - Reason: AI OS must keep seed/demo fallback behavior for fresh clones and missing optional tooling.
* Live destructive smoke testing against operator data - Reason: release validation should avoid mutating private local state by default.
* PRD completion state changes - Reason: the `updateprd` workflow step owns final phase/session completion after validation.

***

## 5. Technical Approach

### Architecture

Use the implemented AI OS source as the authority and the upstream Claude OS `v2.4` tree as a behavior reference. Documentation should explain how AI OS maps upstream behavior into its own architecture: thin TanStack route, modular Knowledge Graph page components, typed client contracts, hook-mediated fetch/admin flows, loopback-only read bridge, token/admin-gated write bridge, shared graph registry files, optional external `graphify`, and seeded fallback data.

The validation record should be evidence-oriented. It should list commands, statuses, relevant test files, manual review outcomes, known blockers, and sanitized residual gaps without embedding private graph contents, local machine paths, credentials, tokens, Playwright binary artifacts, or generated runtime data.

Release metadata should reconcile the current package and README version drift before adding the final Phase 26 changelog entry. The expected implementation flow is to inspect the current package version, choose the next patch release, update package metadata and README consistently, and record the exact version in the changelog and implementation notes.

### Design Patterns

* Source-first docs: verify current source and tests before writing prose.
* Current behavior only: mark unlocks and future tiers as roadmap, not shipped features.
* AI OS-native mapping: document route, component, hook, bridge, and script boundaries instead of copying upstream file organization.
* Fail-closed security language: write endpoints require loopback, token, `HERMES_DASHBOARD_ADMIN=1`, non-demo state, hook-mediated calls, schema validation, and path confinement.
* Bounded evidence: record command names, pass/fail statuses, counts, and sanitized notes only.
* Closeout discipline: if validation fails, record actionable blockers and do not declare Phase 26 parity complete.

### Technology Stack

* TypeScript 6.0.3.
* React 19.
* TanStack Router/Query through existing Knowledge Graph route and hooks.
* Vite 8 local dev middleware.
* Vitest 4.1.6 and Testing Library.
* Playwright 1.60.
* Bun 1.3.14 project scripts.
* Markdown docs under `docs/` and spec evidence under `.spec_system/specs/`.

## 8. Implementation Notes

### Key Considerations

* Current `package.json` is `0.1.300` while `README.md` still shows `0.1.296`; release closeout should reconcile them intentionally.
* `graphify` remains optional. Docs must explain how seed/demo fallback behaves when `graphify` is missing.
* Wire paths intentionally keep upstream `/__graphify_*` names while the route is AI OS-native `/knowledge-graph`.
* The connect prompt and dashboard ingest helper must not expose per-run dashboard tokens in docs, logs, or evidence.
* Upstream docs are references for behavior and wording, not copy-paste file structure.

### Potential Challenges

* Version drift: inspect package, README, changelog, and prior release notes before choosing the final patch version.
* Live ingest optionality: rely on focused tests and seed/demo route behavior when `graphify` or private repositories are unavailable.
* Heavy validation time: record command status and blockers honestly instead of hiding timeouts or environmental failures.
* Documentation breadth: keep docs accurate and linked rather than duplicating every implementation detail in every file.

### Relevant Considerations

* \[P01] **3D vendor chunk budget**: validation must confirm the Knowledge Graph renderer stays lazy and does not regress bundle budgets.
* \[P04] **Hermes bridge guardrails must stay intact**: docs and security review must preserve loopback/token/admin write gates.
* \[P18] **Lazy imports plus cleanup-first effects make 3D UI safe**: route and responsive validation should include lazy renderer fallback behavior.
* \[P24] **Fail-closed bridges need boundary validation**: document graph bridge schema checks, body limits, and explicit error mapping.
* \[P25] **Mission Control writes stay on the shared Hermes admin contract**: grounded chat uses existing admin/chat boundaries and must not imply new route-specific execution paths.

***

## 9. Testing Strategy

### Unit Tests

* Full `bun run test`.
* Focused Knowledge Graph type/parser, hook, admin hook, bridge, component, route, home section, and script tests.

### Integration Tests

* `bun run typecheck`.
* `bun run typecheck:scripts`.
* `bun run lint`.
* `bun run format:check`.
* `bun run build`.
* `bun run budget:check`.
* `bun run runtime:check-private`.

### Manual Testing

* `/knowledge-graph` desktop and mobile review with seed/demo fallback.
* Home Shared Brain section desktop and mobile review.
* Ingest UI review for admin disabled, graphify missing, and no token leakage states.
* Hermes grounded chat review for graph context presentation and existing admin gate boundaries.

### Edge Cases

* Missing `graphify` binary.
* Missing or malformed registry file.
* Missing requested graph id.
* Oversized graph rejection remains documented and tested.
* Invalid GitHub/git URL rejection remains documented and tested.
* Offline, error, empty, seed fallback, demo, admin-disabled, and admin-ready UI states.
