## 4. Smoke Test Results

### LITE Tier

```bash
node ./endiorbot.mjs init --tier LITE --path /tmp/test-lite-150
```

| Check | Result |
|-------|--------|
| Root `CLAUDE.md` | ✅ Created |
| `src/CLAUDE.md` | ✅ NOT created (correct) |
| `tests/CLAUDE.md` | ✅ NOT created (correct) |
| Root has "Context Files" section | ✅ NOT present (correct) |

### STANDARD Tier

```bash
node ./endiorbot.mjs init --tier STANDARD --path /tmp/test-std-150
```

| Check | Result |
|-------|--------|
| Root `CLAUDE.md` | ✅ Created |
| `src/CLAUDE.md` | ✅ Created (30 lines) |
| `tests/CLAUDE.md` | ✅ Created (32 lines) |
| `docs/CLAUDE.md` | ✅ NOT created (correct) |
| Root has "Context Files" section | ✅ Present with `src/` and `tests/` pointers |

### PROFESSIONAL Tier

```bash
node ./endiorbot.mjs init --tier PROFESSIONAL --path /tmp/test-pro-150
```

| Check | Result |
|-------|--------|
| Root `CLAUDE.md` | ✅ Created |
| `src/CLAUDE.md` | ✅ Created |
| `tests/CLAUDE.md` | ✅ Created |
| `docs/CLAUDE.md` | ✅ Created (41 lines) |
| All subdir files < 100 lines | ✅ Verified |

### ENTERPRISE Tier + Service Dirs

```bash
mkdir -p /tmp/test-ent-150/packages/core /tmp/test-ent-150/packages/ui
echo '{"workspaces":["packages/*"]}' > /tmp/test-ent-150/package.json
node ./endiorbot.mjs init --tier ENTERPRISE --path /tmp/test-ent-150
```

| Check | Result |
|-------|--------|
| Root `CLAUDE.md` | ✅ Created |
| `src/CLAUDE.md` | ✅ Created |
| `tests/CLAUDE.md` | ✅ Created |
| `packages/core/CLAUDE.md` | ✅ Detected & created |
| `packages/ui/CLAUDE.md` | ✅ Detected & created |

### Re-init (Additive-Only)

```bash
node ./endiorbot.mjs init --tier ENTERPRISE --path /tmp/test-ent-150
```

| Check | Result |
|-------|--------|
| Existing subdir files preserved | ✅ 24 skipped (hash match) |
| No overwrite without `--force` | ✅ Confirmed |

---

## 5. Design Decisions

| Decision | Rationale |
|----------|-----------|
| `TIER_SUBDIR_CLAUDE_MD` as constant | Centralized config, easy to extend per tier |
| Subdir files generated via `executeStep()` | Reuses existing dry-run, force, hash-check, and preserve logic |
| `generateSubdirClaudeMd()` switch-based | Clean separation of concerns per subdirectory type |
| `< 100 lines` target | Keeps scoped context concise; verified by test assertion |
| ENTERPRISE service detection | Scans `packages/`, `apps/`, `services/`, and `package.json workspaces` |
| Root backward-compat | "Context Files" section appended at end; no restructuring of existing content |

---

## 6. Compliance Check

| Constraint | Status |
|------------|--------|
| `exactOptionalPropertyTypes` | ✅ No `undefined` assigned to optional properties |
| No `any` types | ✅ All types explicit |
| Reuse `collectProjectContext()` | ✅ `snapshot` threaded through from `scaffoldProject` config |
| Root CLAUDE.md backward-compatible | ✅ Only adds "Context Files" section for STANDARD+ |
| Conventional commit ready | `feat(sdlc): add layered CLAUDE.md generation (Sprint 150, ADR-055)` |

---

## 7. Summary

| Category | Result |
|----------|--------|
| Build | ✅ Clean |
| New tests | ✅ 14/14 pass |
| Full regression | ✅ 8,159/8,159 pass |
| Smoke LITE | ✅ No subdir files |
| Smoke STANDARD | ✅ src/ + tests/ |
| Smoke PROFESSIONAL | ✅ src/ + docs/ + tests/ |
| Smoke ENTERPRISE | ✅ + per-service files |
| Re-init preservation | ✅ Additive-only |
| Line count target | ✅ All subdir files < 100 lines |

**Verdict:** Sprint 150 implementation complete and **approved** for merge.
