# Story 4.1: Real Upload Validation

## Summary
Successfully validated real file uploads to Bunny.net storage on October 22, 2025.

## Test Details

**Storage Zone:** 5axislaser925  
**Region:** DE (Frankfurt)  
**File:** story-4.1-test.html  
**Result:** HTTP 201 (Success)  
**Public URL:** https://5axislaser925.b-cdn.net/story-4.1-test.html

## Key Learnings

### 1. Region-Specific URLs
Frankfurt (DE) is the default region and uses a different URL pattern:
- **DE:** `https://storage.bunnycdn.com/{zone}/{file}`
- **Other regions:** `https://{region}.storage.bunnycdn.com/{zone}/{file}`

This was implemented in `BunnyStorageClient._get_storage_url()`.

### 2. Content-Type Requirements
Per Bunny.net API documentation:
- **Required:** `application/octet-stream`
- **NOT** `text/html` or other MIME types
- File content must be raw binary (we use `.encode('utf-8')`)

### 3. Success Response Code
- Bunny.net returns **HTTP 201** for successful uploads (not 200)
- This is documented in their API reference

### 4. Authentication
- Uses per-zone `storage_zone_password` via `AccessKey` header
- Password is stored in database (`site_deployments.storage_zone_password`)
- Set automatically when zones are created via `provision-site` or `sync-sites`
- NO API key from `.env` needed for uploads

## Implementation Changes Made

1. **Fixed region URL logic** - DE uses no prefix
2. **Changed default Content-Type** - Now uses `application/octet-stream`
3. **Updated success detection** - Looks for HTTP 201
4. **Added region parameter** - All upload methods now require `zone_region`

## Test Coverage

**Unit Tests (5):**
- DE region URL generation (with/without case)
- LA, NY, SG region URL generation

**Integration Tests (13):**
- Full upload workflow mocking
- Deployment service orchestration
- URL generation and logging
- Error handling

**Real-World Test:**
- Actual upload to Bunny.net storage
- File accessible via CDN URL
- HTTP 201 response confirmed

## Status
✅ **VALIDATED** - Ready for production use
