# Phase 2: Graph Schema Verification Report

**Phase Goal:** The harness graph understands design concepts natively -- tokens, aesthetic intent, and design constraints are first-class nodes; design relationships are first-class edges; tokens.json and DESIGN.md are auto-ingested into the graph; and enforce-architecture can surface design violations alongside layer violations.
**Verified:** 2026-03-19T17:50:00Z
**Status:** passed
**Re-verification:** No -- initial verification

| 3   | `DesignIngestor` class parses W3C DTCG `tokens.json` and produces `design_token` nodes                 | VERIFIED | `packages/graph/src/ingest/DesignIngestor.ts`: `ingestTokens()` method reads JSON, walks DTCG structure recursively via `isDTCGToken()` check (`$value` + `$type`), creates nodes with type `design_token` including metadata for `tokenType`, `value`, `group`, `description`. Test confirms 7 tokens ingested from fixture with correct metadata.                                                                                             |

Test confirms 1 `aesthetic_intent` node with correct metadata and 3 `design_constraint` nodes matching fixture anti-patterns.                                                                                                                                       |
| 5   | `DesignConstraintAdapter` checks for hardcoded colors/fonts and returns `DESIGN-XXX` violations        | VERIFIED | `packages/graph/src/constraints/DesignConstraintAdapter.ts`: `checkForHardcodedColors()` returns `DESIGN-001` violations for hex colors not in token set; `checkForHardcodedFonts()` returns `DESIGN-002` violations for fonts not in token set. `checkAll()` combines both. Tests confirm violation detection and that token-matching values are not flagged.                                                                                  |

### Human Verification Required

None required. All observable truths are verifiable programmatically through code inspection and test execution.

### Gaps Summary

No gaps found. All 10 observable truths are verified with evidence from actual source code, test fixtures, TypeScript compilation, and test execution. The implementation is substantive (not stubs), fully wired into the graph package, and all 229 tests pass including the 19 new design-specific tests.
