# Quiz-Lead Task 3 — Implementation Report

Date: 20260622

## STATUS: DONE

## Files created/modified

| File | Action |
|------|--------|
| `src/app/api/internal/quiz-lead/route.ts` | CREATED |
| `.env.example` | MODIFIED — added QUIZ_LEAD_SECRET, LISTMONK_URL, LISTMONK_USER, LISTMONK_TOKEN, LISTMONK_QUIZ_LIST_ID |
| `src/middleware.ts` | NOT MODIFIED — `/api/internal` already in PUBLIC_ROUTES with startsWith match; covers /api/internal/quiz-lead without changes |

## Test infra

`grep -E 'vitest|jest' package.json` → no output (empty).
No test framework present. Verification done via `npx tsc --noEmit` + manual reasoning.

## Commands and output

### `npm run type-check`
```
> lms-sb@0.1.0 type-check
> tsc --noEmit

(no output = clean)
```
Exit code: 0

### `npm run lint` (new file only)
```
grep 'quiz-lead' in lint output → no results (no errors in new file)
```

Pre-existing lint errors in repo (36 total, 20 errors) are NOT related to this task:
- `.claude/plugins/superpowers/` scripts using CommonJS require
- `quick-enroll-modal.tsx` — react-hooks/immutability (pre-existing)
- `kinescope-player.tsx` — react-hooks/set-state-in-effect (pre-existing)

## Commit

Base: `9fbb7ae`
New:  `5e65ad6`

```
5e65ad6 Add quiz-lead internal endpoint for Typebot → Listmonk funnel
```

## Implementation notes

- Auth: `x-quiz-secret` header vs `QUIZ_LEAD_SECRET` env var; 401 on mismatch/missing
- Validation: email regex, archetype against const tuple, Number.isFinite(score); 400 on failure
- Upsert logic: POST create → 409 → GET by email SQL query → PUT update; 502 on Listmonk errors
- Middleware: `/api/internal` already in PUBLIC_ROUTES with `startsWith` — no changes needed
- TypeScript strict mode: no `any` used; typed interfaces for Listmonk response shapes
- No production Listmonk list created; LISTMONK_QUIZ_LIST_ID left as empty placeholder in .env.example
- No git push; no deploy

## Concerns

None. The pre-existing lint errors in the repo are unrelated to this task and were already present before this commit.
