+# Verification Report
+
+## 1. Accepted File Types
+- **Claim**: `.mp4`, `.webm`, `.mov`, `.mkv`, `.ts`, `.m3u8`, `.mpg`, `.mpeg`.
+- **Code**: `components/upload-modal.html`
+  ```html
+  <input id="input-file" type="file" class="hidden" accept="video/*,.m3u8,.ts,.mp4,.webm,.mov,.mkv,.mpg,.mpeg" />
+  ```
+- **Status**: **Verified**.
+
+## 2. File Size Limits
+- **Claim**: 2GB recommended due to browser memory hashing.
+- **Code**: `js/services/s3UploadService.js` calls `this.deps.calculateTorrentInfoHash(file)`. `js/utils/torrentHash.js` reads file into memory/buffer for hashing.
+- **Status**: **Verified**.
+
+## 3. Metadata Validation
+- **Claim**: Title required. HTTPS for URLs.
+- **Code**: `js/services/videoNotePayload.js`:
+  ```javascript
+  if (!legacyFormData.title) errors.push(VIDEO_NOTE_ERROR_CODES.MISSING_TITLE);
+  if (legacyFormData.url && !/^https:\/\//i.test(legacyFormData.url)) errors.push(VIDEO_NOTE_ERROR_CODES.INVALID_URL_PROTOCOL);
+  ```
+- **Status**: **Verified**.
+
+## 4. CORS Policy
+- **Claim**: JSON policy provided in docs.
+- **Code**: `js/storage/s3-multipart.js` `ensureBucketCors` constructs the policy dynamically but matches the structure (AllowedOrigins, AllowedMethods, AllowedHeaders=["*"], ExposeHeaders=[ETag, ...]).
+- **Status**: **Verified**.
+
+## 5. Upload Lifecycle
+- **Claim**: "The client handles the upload, generates a magnet link...".
+- **Code**: `js/ui/components/UploadModal.js` `handleVideoSelection` uploads video, then calls `generateTorrentMetadata`, then uploads `.torrent` file if successful.
+- **Gap**: Docs do not explicitly mention that a `.torrent` file is also uploaded to the bucket.
+- **Recommendation**: Update docs to mention `.torrent` file generation and upload.
+
+## 6. S3/R2 Configuration
+- **Claim**: Supports S3 and R2.
+- **Code**: `js/services/s3Service.js` and `js/services/storageService.js` handle these providers.
+- **Status**: **Verified**.
