**Version**: claude-faf-mcp v3.0.4+
**Source**: Ported from faf-cli v3.2.5
**Tester**: Championship Tools Team
**Philosophy**: *"We break things so others never have to know they were broken."*

---

## Executive Summary

**Objective**: Validate TYPE_DEFINITIONS implementation in MCP bundled compiler matches faf-cli behavior exactly, covering all 94 project types, 38 aliases, and slot calculation edge cases.

**Status**: CHAMPIONSHIP GRADE - All 35 edge case tests passing

**Risk Level**: LOW - Full parity with faf-cli achieved

## WJTTC Tier 8: TYPE_DEFINITIONS Vigor

### What is TYPE_DEFINITIONS?

TYPE_DEFINITIONS is the core system that determines which slots count for scoring based on project type. Different project types have different slot requirements:

| Project Type | Slot Count | Categories |
|-------------|-----------|------------|
| `cli`, `library`, `k8s` | 9 | project(3) + human(6) |
| `mobile`, `dapp` | 13 | project(3) + frontend(4) + human(6) |
| `mcp-server`, `data-science` | 14 | project(3) + backend(5) + human(6) |
| `frontend`, `react`, `vue` | 16 | project(3) + frontend(4) + universal(3) + human(6) |
| `backend-api`, `node-api` | 17 | project(3) + backend(5) + universal(3) + human(6) |
| `fullstack`, `nextjs`, `monorepo` | 21 | ALL categories |

### Why Tier 8?

TYPE_DEFINITIONS is the **mathematical foundation** of FAF scoring:
- Wrong slot counts = wrong scores = broken trust
- Aliases must resolve correctly (k8s -> kubernetes)
- slot_ignore must parse all formats (array, string, shorthand)
- Edge cases can silently corrupt scoring

---

## Test Scope: 7 Categories, 35 Tests

### Category 1: Similar Type Differentiation (4 tests)

**Why Critical**: Similar types (cli vs cli-tool, react vs vue) must produce correct slot counts.

| Test | Types Compared | Expected Slots | Status |
|------|---------------|----------------|--------|
| cli vs cli-tool | Both alias to cli | 9 | PASS |
| frontend vs react vs vue | All frontend types | 16 | PASS |
| backend-api vs node-api vs python-api | All backend types | 17 | PASS |
| mcp-server | Backend without universal | 14 | PASS |

### Category 2: Alias Resolution (10 tests)

**Why Critical**: 38 aliases must resolve to canonical types correctly.

| Alias | Resolves To | Expected Slots | Status |
|-------|-------------|----------------|--------|
| k8s | kubernetes | 9 | PASS |
| tf | terraform | 9 | PASS |
| rn | react-native | 13 | PASS |
| expo | react-native | 13 | PASS |
| flask | python-api | 17 | PASS |
| fastapi | python-api | 17 | PASS |
| express | node-api | 17 | PASS |
| next | nextjs | 21 | PASS |
| turbo | turborepo | 21 | PASS |
| gha | github-action | 9 | PASS |

### Category 3: slot_ignore Edge Cases (6 tests)

**Why Critical**: slot_ignore is the escape hatch for customizing scoring.

| Test | Input Format | Expected Behavior | Status |
|------|--------------|-------------------|--------|
| Array format | `['human.who', 'human.what']` | 9 - 2 = 7 slots | PASS |
| String format | `'human.who, human.what'` | 9 - 2 = 7 slots | PASS |
| Shorthand | `['who', 'what']` | Expands to human.* | PASS |
| Stack slots | `['stack.database']` | 17 - 2 = 15 slots | PASS |
| Empty array | `[]` | No effect | PASS |
| Non-existent slot | `['nonexistent']` | Ignored gracefully | PASS |

### Category 4: Fallback Behavior (3 tests)

**Why Critical**: Unknown/missing types must degrade gracefully.

| Test | Input | Expected Behavior | Status |
|------|-------|-------------------|--------|
| Unknown type | `'unknown-project-type'` | Falls back to generic (12 slots) | PASS |
| Missing type | No type field | Falls back to generic | PASS |
| Null type | `type: null` | Falls back to generic | PASS |

### Category 5: Monorepo/Container Types (3 tests)

**Why Critical**: Monorepos need all 21 slots.

| Test | Type | Expected Slots | Status |
|------|------|----------------|--------|
| monorepo | monorepo | 21 | PASS |
| nx | nx | 21 | PASS |
| lerna | lerna | 21 | PASS |

### Category 6: Score Calculations (3 tests)

**Why Critical**: Score = filled/total must be mathematically correct.

| Test | Scenario | Expected | Status |
|------|----------|----------|--------|
| 100% score | All slots filled | score = 100, filled = total | PASS |
| Partial score | Missing slots | score < 100, filled < total | PASS |
| Denominator matches type | CLI=9, Fullstack=21 | Correct totals | PASS |

### Category 7: Special Type Cases (6 tests)

**Why Critical**: Unusual project types must have correct slot assignments.

| Type | Category | Expected Slots | Status |
|------|----------|----------------|--------|
| chrome-extension | 9-slot | 9 | PASS |
| smart-contract | 9-slot | 9 | PASS |
| jupyter | 9-slot | 9 | PASS |
| data-science | 14-slot (backend) | 14 | PASS |
| ml-model | 14-slot (backend) | 14 | PASS |
| dapp | 13-slot (frontend) | 13 | PASS |

## MCP-CLI Parity

### The Connection

TYPE_DEFINITIONS were **ported from faf-cli v3.2.5** to the MCP bundled compiler. This test suite validates:

1. **Same slot counts**: MCP compiler produces identical slot assignments
2. **Same alias resolution**: k8s -> kubernetes works in both
3. **Same slot_ignore parsing**: All formats (array, string, shorthand) work
4. **Same fallback behavior**: Unknown types degrade gracefully

### Why Both Need Testing

```
┌─────────────────┐     ┌─────────────────┐

├─────────────────┤     ├─────────────────┤
│ TYPE_DEFINITIONS│ === │ TYPE_DEFINITIONS│  <- MUST BE IDENTICAL

                    ▼
           ┌───────────────┐
           │  Same Score   │
           │  Same Output  │
           │  Same Trust   │
