# Dimentorin — Catatan Temuan Infra (Dev Audit, 2026-08-04)
Dokumen ini mencatat temuan yang membutuhkan perhatian tim sebelum produksi.
Semua diuji lokal (Postgres `dimentorin`, backend :4099).
## 1. SMTP email verification broken (blocker aktivasi user baru) — ✅ FIXED (2026-08-05, Google App Password)
- Endpoint `POST /v1/iam/auth/send-otp` gagal: `SMTP transport error (535): Username and Password not accepted` — kredensial `.env` (`SMTP_EMAIL=dev@example.com`, `SMTP_PASSWORD=dev`) ditolak Google SMTP.
- `POST /v1/iam/auth/verify-email` tetap butuh OTP untuk memanggil, tapi lihat poin 2.
- **Dampak**: mentee/mentor baru tak bisa menerima OTP lewat email → tak bisa aktivasi → tak bisa login, kecuali via verify-email langsung.
- **Diperlukan**: SMTP credential institution yang valid (Gmail App Password atau SMTP relay), sebaiknya dari BWS secret management, bukan hardcode.
## 2. ✅ FIXED — verify-email TIDAK memverifikasi OTP (security issue)
**Status: FIXED di branch feat/dimentorin-postgres (2026-08-04).**
`imphnen-iam/src/auth/application/mod.rs``verify_email()`:
- OTP sekarang dipersist ke tabel **`app_otp_cache`** (entity baru `imphnen-entities/src/seaorm/common/otp_cache.rs`, resource `app_otp_cache` sudah direncanakan di `ResourceEnum::OtpCache`).
- `register()` & `resend_otp()` menyimpan `otp_hash` + `expires_at` setelah email terkirim (kalau email gagal, tidak ada OTP yatim / OTP lama tidak di-overwrite).
- `verify_email()` memanggil `OtpManager::validate_otp_hash(stored_hash, expires_at, payload.otp)` sebelum set `is_active`. `validate_otp_hash` ditambahkan ke `OtpManager` (pure hash+expiry tanpa perlu plaintext code).
- OTP **single-use**: di-delete setelah verifikasi sukses. Reuse / OTP tanpa cache / OTP expired semua ditolak (400).
- Uji lokal (Postgres, :4099): OTP salah → 400 "Invalid or expired OTP", user tetap inactive; OTP benar → 200 "Email verified successfully", user aktif, OTP dihapus; verify ulang → 400 "User already active"; email tanpa OTP → 400 "No OTP issued".
- Tabel dibuat via SQL manual (`create_schema.rs` ditambah `otp_cache` untuk bootstrap penuh).
## 3. (OK, sudah benar) Register mentor + booking
- `POST /v1/dimentorin/mentors/create` → 200, user + mentor profile dibuat, status `pending`, user tak tampil di list public sampai verified.
- `POST /v1/dimentorin/mentors/{id}/sessions/create` → 200, session pending.
- Kedua endpoint fungsional setelah fix UUID (commit 9b5efef).
## Rekomendasi
Tangani #1 dan #2 sebelum go-live. #2 adalah kelas bug "OTP di-generate tapi tak dipakai" — sisi verifikasi email saat ini tidak lebih dari form "set is_active=true tanpa autentikasi".
## 4. ✅ DONE — Payment flow (alur bisnis menjual)
**Status: DONE di feat/dimentorin-postgres (2026-08-05).**
- Tabel `app_payments`: amount (dari `mentoring_rate` mentor) + service_fee 2000 + total; method `va`/`qris`/`manual`; provider `manual` default (swap Midtrans/Xendit nanti — cukup ganti nilai `provider` dan implementasi `generate_external_ref`/notifikasi webhook).
- Routes protected: `POST /payments/sessions/{id}/create`, `GET /payments/me`, `GET /payments/{id}`, `POST /payments/{id}/confirm`.
- Guard: mentee hanya bisa akses payment miliknya (403 kalau bukan); confirm hanya Admin / Admin Pembayaran.
- `confirm_payment` otomatis mengubah session terkait `pending` -> `confirmed` (loop bisnis lengkap: book -> bayar -> sesi terkonfirmasi -> feedback).
- FE: PaymentStep pilih VA/QRIS, rate real dari `mentoring_rate`; modal appointment: book -> create payment -> tampil VA/QR dengan `external_ref` + total + expiry -> success. Service lib: `postCreatePayment/getMyPayments/getPaymentById/postConfirmPayment`.
- E2E verified (lokal :4099): create VA dan QRIS, confirm 200, re-confirm 409, non-admin 403, akses payment orang lain 403, session auto-confirmed.
- TODO produksi: isi kredensial payment gateway (Midtrans/Xendit) + webhook callback; SMTP masih blocker (#1).
## 5. Payment lifecycle complete: auto-paid refresh + dashboards (2026-08-05)
- POST /payments/{id}/refresh: polls Midtrans v2/{order_id}/status; settlement/capture -> payment paid + session confirmed automatically (e2e verified via sandbox simulator: VA paid -> refresh -> paid + confirmed)
- GET /payments/session/{id}: payments for one session, accessible by that session's mentee or mentor (powers both dashboards)
- Session mentor may confirm their own payments (previously admins only) — verified e2e
- FE: /mentoring/my-sessions (mentee) + /mentoring/mentor-dashboard (mentor), both with live payment status and refresh/confirm actions; QRIS step renders real QR from qr_string
## 6. Materi + AI Agent RAG (2026-08-05, commit 164c186 BE / 7294040 FE)
Fitur yang "harusnya ada" menurut user (Figma hanya berisi Design System, halaman Materi/AI Agent tidak ada di file) — dibangun dari pemahaman alur bisnis mentoring.
**Backend — modul materials** (`imphnen-dimentorin/src/materials/`):
- `app_materials` table: mentor_id, title, slug, category, description, content, cover_url, is_published
- Pola articles: domain/repository/service + postgres repo + DTO ZodValidate
- Routes: GET /materials (public, published), /materials/{id|slug|categories}, POST/PUT/DELETE (auth, author-only)
- ENV baru: AI_LLM_BASE_URL/API_KEY/MODEL, AI_EMBEDDING_MODEL, QDRANT_URL
**Backend — AI agent RAG** (`imphnen-dimentorin/src/ai_agent/`):
- Chunking materi (700 chars, overlap 80) -> embed via 9router `gemini/gemini-embedding-001` (3072 dim!)
- Qdrant collection `dimentorin_materi` (3072d cosine, point id = u64 dari uuid xor index — Qdrant TOLAK string non-UUID)
- Chat: embed question -> search top-4 -> LLM (`text` -> gemini-3.1-flash-lite) jawab dengan konteks + sources
- Routes: POST /ai/chat, POST /ai/materials/{id}/index, POST /ai/reindex
- 9router chat SELALU SSE-streaming walau tanpa stream:true — parser harus agregate `data:` lines
**Verified e2e**: reindex 3 chunks; chat 'ownership' -> source materi Rust 0.88; chat 'endpoint axum' -> Axum 0.82; browser: list materi, detail, chatbox jawab + sources 84/64/61%.
**Pitfall**: embedding Gemini = 3072 dim (bukan 768); Qdrant point id harus u64/UUID; model embedding yang berfungsi di 9router = `gemini/gemini-embedding-001` (llama-nemotron -> 'No credentials for provider: openai').
