+# TeleUploader — Audit & Optimisasi Stabilitas + S3 (2026-08-27)
+
+## Scope
+Audit dan optimasikan backend TeleUploader agar stabil di segala situasi dan
+S3 protocol stabil + secepat mungkin. Fokus pada bottleneck nyata yang
+ditemukan saat audit kode + log.
+
+## Temuan Audit (root cause → prioritas)
+
+### A. S3 GET lambat (bottleneck terbesar download)
+1. **`concatPartStreams` (object-stream.ts) fetch part SEQUENTIAL** — tiap part
+   di-`fetch` satu per satu (for..of + await penuh). Untuk objek chunked/multipart
+   dengan N part, byte pertama baru terkirim SETELAH semua fetch part selesai.
+   → **PARALELISASI** dengan bounded concurrency, urut tetap dipertahankan.
+2. **`buildChunkedObjectSources` & `handleGetMultipartObject` resolve
+   `getFileInfo` SEQUENTIAL** (for..of + await). N call Telegram API berurutan
+   sebelum streaming mulai.
+   → **`Promise.all`** resolve paralel.
+3. **`botPool.getFileInfo` TIDAK pakai `fileInfoCache`** yang sudah ada — setiap
+   S3 GET objek reguler memanggil API Telegram `getFile` (network round-trip).
+   file-controller punya wrapper cache sendiri, tapi path S3 tidak.
+   → **pindahkan caching ke dalam `botPool.getFileInfo`** agar semua caller dapat.
+
+### B. Stabilitas / lingkungan produksi
+4. **`nodeEnv: "development"` di produksi** (dari log BWS). Winston format json
+   sudah benar di production, tapi flag salah.
+5. **`trustProxy: false` di produksi padahal di belakang Caddy** → rate limiter
+   meng-key semua user ke `127.0.0.1` (satu bucket global). Ini bug kecil untuk
+   non-S3 route. Fix: default trustProxy menyesuaikan, tapi utama via env.
+6. **MemoryMax=512M di systemd** padahal config mendukung blob 2GB. Streaming
+   PUT O(1) memory, tapi GET gzip part membuffer part utuh. Naikkan ke 1G.
+
+### C. Robustness S3
+7. **`handleUploadPart` tidak `await writer.end()`** sebelum `createReadStream`
+   → potensi race baca file belum flush. Await end().
+8. Batas kecepatan unggah: `telegramBotConcurrency:1` × 6 bot = 6 unggah paralel.
+   Karena Telegram ~1 rps/bot untuk sendDocument, konkuransi per-bot 1 masuk
+   akal. Biarkan default, tapi pastikan pool retry terhadap 429 sudah bagus
+   (sudah, ada retry-after handling).
+
+## File yang disentuh (semua di bawah src/)
+- `src/interfaces/s3/object-stream.ts` — paralelisasi fetch part (concatPartStreams)
+- `src/infrastructure/telegram/bot-pool.ts` — getFileInfo + cache, resolve paralel
+- `src/infrastructure/telegram/chunked-storage.ts` — buildChunkedObjectSources paralel
+- `src/interfaces/http/controllers/s3-controller.ts` — handleGetMultipartObject paralel,
+  await writer.end() di handleUploadPart
+- `src/infrastructure/cache/index.ts` — (opsional) tambah helper
+
+## Verifikasi
+- `bunx biome check src test` (lint)
+- `bun test test/s3-auth.test.ts` & `test/s3-operations.test.ts` (S3 regresi)
+- `bun test test/telegram.test.ts` (pool) kalau ada
+- Test unit baru untuk parallel part streaming (tanpa network) kalau layak.
+- Deploy via push main → CI `deploy.yml` (Nix build → nix copy → systemctl restart).
+
+## Deploy
+Push ke `main` → GitHub Actions `deploy.yml` build + deploy Nix ke orangevps.
+Setelah deploy, verifikasi `/health` 200 dan S3 GET masih berfungsi.
