# Validation Report

**Session ID**: `phase26-session01-graph-data-contracts-seed-fixtures` **Reviewed**: 2026-06-09 **Result**: PASS

***

## Scope

**Files reviewed**:

* `.spec_system/specs/phase26-session01-graph-data-contracts-seed-fixtures/spec.md`
* `.spec_system/specs/phase26-session01-graph-data-contracts-seed-fixtures/tasks.md`
* `.spec_system/specs/phase26-session01-graph-data-contracts-seed-fixtures/implementation-notes.md`

* `src/lib/__tests__/knowledge-graph-types.test.ts`
* `src/data/graphs/index.json`
* `src/data/graphs/ai-os.json`

**Review method**: session document review, artifact existence check, ASCII/LF spot-check, JSON parse compatibility check, and test command verification.

***

## Check Results

### Task Completion

**Status**: PASS

* All 20 tasks are marked complete in `tasks.md`.

### Deliverables

**Status**: PASS

* The session deliverables exist and are non-empty.
* The contract, demo fixture, test, and seed data files are present at the declared paths.

### ASCII And Line Endings

**Status**: PASS

* `file` reports ASCII text for the new TypeScript deliverables.
* `grep` checks found no non-ASCII characters in the new contract, demo, test, and JSON artifacts.
* `grep` checks found no CRLF line endings in the reviewed deliverables.

### Validation Evidence

**Status**: PASS

* `bun run test -- src/lib/__tests__/knowledge-graph-types.test.ts` passed with 1 test file and 9 tests.
* `bun run typecheck` passed.
* `bun run test` passed with 248 test files and 3194 tests.
* `jq empty src/data/graphs/index.json src/data/graphs/ai-os.json` passed earlier during implementation.

### Success Criteria

**Status**: PASS

* `parseKnowledgeGraph()` accepts valid graphify node-link graphs and rejects malformed payloads.
* Registry parsing accepts the checked-in seed registry and rejects malformed ids, counts, colors, god nodes, and graph paths.
* Demo fixtures parse through the same public contract as the seed data.
* Savings estimate behavior is typed, bounded, and deterministic.

### Conventions Spot Check

**Status**: PASS

* No obvious naming, structure, or error-handling issues were found in the new contract surface.

***

## Conclusion

The Knowledge Graph contract and seed-fixture session is validated successfully. The session artifacts are complete, the deliverables are present, and the test and typecheck evidence is sufficient for session closeout.

# 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-session01-graph-data-contracts-seed-fixtures/validation.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.
