+# 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.

+- Guard fail-fast di `src/env.ts`: service MENOLAK start (exit non-zero) jika `TELEGRAM_CHUNK_SIZE_BYTES` > 19922944 (19 MB, margin aman dari limit 20 MB). Konstanta: `TELEGRAM_CHUNK_SIZE_MAX_BYTES` di `src/shared/utils/validation.ts`, juga dipakai `asSafeChunkSize()` di runtime.
+- Default 19 MB; berlaku untuk chunked storage DAN S3 multipart parts (sama-sama disimpan ke Telegram lalu di-resolve via getFile).

 ## Testing
 
 Use `bun test` to run tests. Jalankan tes secara spesifik (misal `bun test test/rateLimit.test.ts`) untuk menghindari polusi mock antar berkas tes ketika dijalankan bersamaan.

+# Per-Bot Queue Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Replace global PQueue with per-bot queues (concurrency=1 per bot) to eliminate 429 collisions and improve rate-limit safety.
+
+**Architecture:** Each bot token gets its own PQueue with concurrency=1. Uploads are assigned to the least-loaded available bot via `selectBot()`. On 429, the bot is marked rate-limited and the upload retries on the next available bot. The global `upload-queue.ts` is removed; `uploadConcurrency` config is replaced by `botCount * perBotConcurrency`.
+
+**Tech Stack:** TypeScript, PQueue, Telegraf
+
+## Global Constraints
+
+- Use `Bun` runtime, not Node.js
+- Follow existing code style (Biome lint)
+- Each bot queue has concurrency=1 (no two uploads hit same bot simultaneously)
+- `selectBot()` picks bot with lowest pending queue count, skipping rate-limited bots
+- Remove `uploadConcurrency` from config; derive effective concurrency from bot count
+- Remove `upload-queue.ts` entirely
+- Remove `enqueueUpload` from `ITelegramService` interface
+
+---
+## File Structure
+
+### Files to Modify
+| File | Change |
+|------|--------|
+| `src/infrastructure/telegram/bot-pool.ts` | BotEntry array, selectBot(), per-bot queues, retry logic |
+| `src/domain/ports/telegram-service.ts` | Remove `enqueueUpload` from interface |
+| `src/env.ts` | Remove `uploadConcurrency` field |
+| `src/index.ts` | Remove upload-queue import and usage |
+| `src/utils/chunked-storage.ts` | Replace `config.uploadConcurrency` with bot count |
+
+### Files to Delete
+| File | Reason |
+|------|--------|
+| `src/infrastructure/telegram/upload-queue.ts` | Global queue replaced by per-bot queues |
+| `test/telegramQueue.test.ts` | Tests for deleted module |
+
+### Files Not Changed
+| File | Reason |
+|------|--------|
+| `test/bot.test.ts` | Only uses ITelegramService interface (via `forwardToStorage`) |
+| `src/infrastructure/telegram/chunked-storage.ts` | Uses ITelegramService interface, not BotPool directly |
+
+---
+
+### Task 1: Refresh the spec & plan files after compaction
+
+Due to context compaction, re-read the current spec and plan files to ensure accuracy before implementing.
+
+- [ ] **Step 1: Re-read the spec**
+
+Read: `docs/superpowers/specs/2026-07-29-per-bot-queue-design.md`
+
+- [ ] **Step 2: Re-read key implementation files**
+
+Read: `src/infrastructure/telegram/bot-pool.ts`, `src/env.ts`, `src/utils/chunked-storage.ts`
+
+### Task 2: Refactor ITelegramService interface
+
+Remove `enqueueUpload` from the interface — BotPool handles queueing internally now.
+
+**Files:**
+- Modify: `src/domain/ports/telegram-service.ts`
+
+- [ ] **Step 1: Remove `enqueueUpload` from interface**
+
+```typescript
+// src/domain/ports/telegram-service.ts — remove entire section:
+  /**
+   * Enqueue a task for sequential upload execution.
+   *
+   * Ensures only one Telegram upload runs at a time to avoid
+   * rate limits and resource contention.
+   *
+   * @param task - An async function performing the upload.
+   * @returns The result of the task.
+   */
+  enqueueUpload<T>(task: () => Promise<T>): Promise<T>;
+```
+
+- [ ] **Step 2: Run lint to verify**
+
+Run: `bunx biome check src/domain/ports/telegram-service.ts`
+Expected: No errors.
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/domain/ports/telegram-service.ts
+git commit -m "refactor: remove enqueueUpload from ITelegramService
+
+Per-bot queue handles queueing internally.
+
+Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>"
+```
+
+### Task 3: Refactor BotPool with per-bot queues
+
+The core of the redesign. Replace `claimBotIndex()` round-robin with per-bot PQueue instances and `selectBot()` for least-loaded assignment.
+
+**Files:**
+- Modify: `src/infrastructure/telegram/bot-pool.ts`
+
+**Interfaces:**
+- Consumes: `ITelegramService` (no `enqueueUpload` method)
+- Produces: `botPool` singleton with per-bot queues, `selectBot()`, per-bot rate-limit tracking
+
+- [ ] **Step 1: Write test file for per-bot queue behavior**
+
+```typescript
+// test/bot-pool.test.ts
+import { beforeEach, describe, expect, it, mock, spyOn } from 'bun:test';
+
+// We'll test the BotEntry queue behavior and selectBot logic
+```
+
+- [ ] **Step 2: Implement BotEntry type and BotPool refactor**
+
+Replace the class body:
+
+```typescript
+import PQueue from 'p-queue';
+import { Telegraf } from 'telegraf';
+import type {
+  ForwardResult,
+  ITelegramService,
+  TelegramFileInfo,

+### Task 5: Update env.ts and chunked-storage backpressure
+
+Remove `uploadConcurrency` from config and update chunked-storage to derive effective concurrency from bot pool.
+
+**Files:**
+- Modify: `src/env.ts`
+- Modify: `src/utils/chunked-storage.ts`
+
+- [ ] **Step 1: Remove `uploadConcurrency` from env.ts**
+

+
+Replace:
+```typescript
+import { config } from '../env';
+// ...
+if (inFlight.size >= config.uploadConcurrency * 2) {
+```
+With:
+```typescript
+import { botPool } from '../infrastructure/telegram/bot-pool';
+// ...
+if (inFlight.size >= botPool.getEffectiveConcurrency()) {
+```
+(Use effective concurrency * 2 for backpressure, or just use effective concurrency as the limit.)
+
+Actually let me think about this more carefully. The backpressure in chunked-storage:
+```
+if (inFlight.size >= config.uploadConcurrency * 2) {
+  await Promise.race(inFlight);
+  await new Promise((resolve) => setTimeout(resolve, 0));
+}
+```
+
+This limits the number of in-flight chunks per file. With `uploadConcurrency: 16`, it was 32. Now with effective concurrency of 6 (6 bots), it would be 12. That's fine as backpressure — it prevents too many chunks from being in memory at once.
+
+Let me use `botPool.getEffectiveConcurrency() * 2` to keep the same multiplier.
+
+- [ ] **Step 3: Run lint and tests**
+
+```bash

+# Per-Bot Queue: Rate-Limit Safe Telegram Upload
+
+**Date:** 2026-07-29
+**Status:** Approved Design
+
+## Problem
+
+Telegram Bot API rate-limits each bot to approximately 1-2 concurrent uploads. When multiple upload chunks hit the same bot simultaneously, Telegram returns HTTP 429 (Too Many Requests), causing delays of 30-60 seconds per retry. Under Docker push load, these cumulative delays trigger Gitea client timeouts and `500 Internal Server Error`.
+
+> Catatan (2026-08-02): Produksi sekarang port 4000, deploy Nix+systemd di orangevps, Caddy reverse proxy upload.asepharyana.my.id, DB via pgbouncer pool imrnes 100.121.180.82:6432. Docker/Traefik/Gitea-CI legacy.
+
+The current architecture uses a **global PQueue** with `concurrency=N` where each task picks a bot via round-robin (`claimBotIndex()`). This means two concurrent tasks can both land on the same bot index (after wrap-around), causing 429 collisions.
+
+## Solution: Per-Bot Queue
+
+Each bot has its own PQueue with `concurrency=1`. Uploads are assigned to the bot with the fewest pending tasks. If a bot rate-limits, the upload moves to the next available bot.
+
+### Architecture

+  │   │
+  │   ├─ selectBot(attemptedIndexes)

+  │   │   ├─ Filter out already-attempted bots

+  │   │   │   └─ Retry selectBot
+  │   │   └─ Return bot with smallest queue.pending count
+  │   │
+  │   ├─ attemptedIndexes.add(selectedBot)
+  │   │
+  │   ├─ result = await bots[selectedBot].queue.add(() =>
+  │   │     executeTelegramCall(bot, fileChunk, fileName)
+  │   │   )
+  │   │   │

+  │   │   │

+  │   │       ├─ 429 → markRateLimited(bot, retryAfter)
+  │   │       │        → continue to next bot in retry loop
+  │   │       ├─ Transient (timeout, 5xx) → continue
+  │   │       └─ Non-transient → throw (propagate up)
+  │   │
+  │   └─ Attempt counter exhausted → throw lastError
+  │
+  └─ Sorted part tracking (for chunked uploads)
+```
+
+### Key Design Decisions
+
+1. **Concurrency=1 per bot**: Guarantees no two Telegram API calls compete for the same bot token. With 6 bots, effective concurrency = 6.
+
+2. **Least-loaded assignment**: `selectBot()` picks the bot with the fewest queued + pending tasks. This naturally load-balances even when some bots are slower.
+
+3. **Rate-limit isolation**: When bot A hits 429, only bot A's queue is paused. Other 5 bots continue serving uploads uninterrupted.
+
+4. **Per-bot rate-limit timer**: `rateLimitedUntil` prevents re-selecting a recently-429'd bot until its cooldown expires.
+
+5. **No global PQueue**: The old `upload-queue.ts` is removed. Each bot owns its queue, eliminating the global backpressure problem.
+
+### Changes by File
+
+| File | Action |
+|------|--------|
+| `src/infrastructure/telegram/bot-pool.ts` | **Major refactor**: BotEntry array, selectBot(), per-bot queues, retry loop |
+| `src/infrastructure/telegram/upload-queue.ts` | **Delete**: No longer needed |
+| `src/domain/ports/telegram-service.ts` | **Remove** `enqueueUpload<T>(task: () => Promise<T>): Promise<T>` from interface |
+| `src/utils/chunked-storage.ts` | **No changes** — only uses `forwardToStorage()` |
+| `src/env.ts` | **Remove** `uploadConcurrency` config (no longer needed) |
+
+### Error Handling
+
+- **429 per bot**: Mark bot rate-limited, move to next. Clear timer after `retryAfter` seconds.
+- **All bots 429**: Sleep 5 seconds with jitter, then retry from bot 0.
+- **Transient errors** (timeout, 5xx, connection reset): Retry on same bot (inside its queue), then on next bot.
+- **Non-transient errors** (4xx other than 429, wrong file_id, auth errors): Propagate immediately.
+- **MAX_RETRIES**: 10 attempts across all bots before giving up.
+
+### Testing
+
+- Unit: `selectBot()` returns bot with fewest pending tasks
+- Unit: `selectBot()` skips rate-limited bots
+- Unit: 429 on bot 0 → retries on bot 1 → succeeds
+- Unit: All bots rate-limited → sleeps → retries → succeeds
+- Unit: Per-bot queue has concurrency=1 (two tasks to same bot queue sequentially)
+- Integration: Forward a real file through the per-bot pool
