**All 18 YAML data files + config schema + tests: 20/20 files exist.**

### Level 2 -- SUBSTANTIVE

- **Industry files:** Each contains `name`, `description`, `styles` (primary/secondary/avoid), `palette` (primary/accent/neutral with hex+usage), `typography` (heading/body/mono families with weights). Verified saas.yaml in detail -- rich, production-quality data with specific hex colors, font families, and avoid lists.
- **Anti-pattern files:** Each contains `description` and `patterns` array with `name`, `severity`, `scope`, `detect` (methods/values), `reason`, `instead` (fix guidance), and `strictness` mapping (permissive/standard/strict). Verified typography.yaml -- real detection logic with CSS property targeting.
- **Palettes:** `curated.yaml` has named palettes with tags, 8 color roles each, pre-validated WCAG contrast pairs with ratios and pass levels (AA/AAA).
- **Typography:** `pairings.yaml` has named pairings with display/body/mono families, fallback stacks, weights, variable font flags, sources, and complete type scales.
- **Platform rules:** Each has `platform`, `frameworks`, `styling`, `token_binding` methods with priority/examples, and `component_patterns` with rules/examples.
- **Config schema:** `DesignConfigSchema` is a proper Zod schema with `strictness` enum (strict/standard/permissive defaulting to standard), `platforms` array enum (web/mobile defaulting to []), optional `tokenPath` string, optional `aestheticIntent` string. Integrated into `HarnessConfigSchema` as optional `design` field.
- **Tests:** 17 test cases covering valid/invalid inputs, defaults, type validation, and integration with HarnessConfigSchema.

### Level 3 -- WIRED

- `DesignConfigSchema` is exported from `schema.ts` and used in `HarnessConfigSchema.design` field
- `DesignConfig` type is exported for downstream consumption
- Tests import from the actual schema module and validate real behavior
- All tests pass in full suite

**Phase 1 verdict: VERIFIED**

| `packages/graph/tests/constraints/DesignConstraintAdapter.test.ts` | 157   | EXISTS |

### Level 2 -- SUBSTANTIVE

- **types.ts:** Contains `design_token`, `aesthetic_intent`, `design_constraint` as node types and `uses_token`, `declares_intent`, `violates_design`, `platform_binding` as edge types.
- **DesignIngestor:** Full implementation with:
  - `ingestTokens()`: Reads tokens.json, recursively walks W3C DTCG structure, creates `design_token` nodes with tokenType, value, group, and description metadata. Handles parse errors gracefully.
  - `ingestDesignIntent()`: Reads DESIGN.md, extracts Style/Tone/Differentiator/strictness via regex, creates `aesthetic_intent` node. Parses anti-patterns section to create `design_constraint` nodes.
  - `ingestAll()`: Runs both in parallel via `Promise.all`, merges results.
  - Uses `ingestUtils.ts` for hash, mergeResults, emptyResult helpers.
- **DesignConstraintAdapter:** Full implementation with:
  - `checkForHardcodedColors()`: Gets color token values from graph, extracts hex codes from source, reports violations for non-token colors. Severity controlled by strictness parameter.
  - `checkForHardcodedFonts()`: Similar pattern for font-family values.
  - `mapSeverity()`: Maps strictness levels to severity (strict->error, standard->warn, permissive->info).
  - Proper `DesignViolation` interface with code, file, message, severity, value, suggestion fields.

### Level 3 -- WIRED

- `DesignIngestor` exported from `packages/graph/src/index.ts`
- `DesignConstraintAdapter` exported from `packages/graph/src/index.ts`
- `DesignViolation` and `DesignStrictness` types exported from index
- Both test files exist with 182 and 157 lines respectively
- All graph tests pass in full suite

**Phase 2 verdict: VERIFIED**
