# Batch 4: Content Delivery + Rendering Verification

## 1. ViewContent.svelte Assessment

**Status: CORRECT**

- **Multi-file display**: Correctly branches on `metadata.files.length === 1` vs multi-file.
- **Metadata rendering**: Displays:
  - `created_at` via `new Date(metadata.created_at).toLocaleString()`
  - `total_size` via `formatSize(metadata.total_size)`
  - `author` conditionally (`{#if metadata.author}`), linking to `https://t.me/{username}`
- **Password propagation**: `password` state is initialized from `sc` prop and passed to all `fileUrl()` / `rawUrl()` calls for single-file viewers.
- **Viewer routing**: `getViewerFor()` maps `render_flags` to the correct component.

## 2. MixedGallery.svelte Assessment

**Status: CORRECT**

- **Multi-file handling**: Iterates `files` with keyed `{#each}` (`(file.idx)`), rendering each in its own panel with index and filename header.
- **Password propagation**: The `password` prop (default `''`) is passed to **every** `fileUrl()` and `rawUrl()` call across all viewer types (image, video, audio, markdown, text, pdf, docx, dangerous, sensitive, document). This ensures password-protected multi-file galleries load correctly.
- **Consistency**: Uses the same viewer mapping logic as `ViewContent.svelte`.

## 3. Frontend Display Issues Affecting Submission/Forward System

**No blocking issues found.**

### Author Visibility Toggle
- The backend supports `show_author: bool` (database + API).
- The server returns `author: Option<AuthorInfo>`; when `show_author` is `false`, `author` is `null`.
- The frontend respects this via `{#if metadata.author}` — no author block is rendered when hidden.
- **Conclusion**: Author visibility toggle works end-to-end.

### Password Field Behavior
- `Home.svelte`: Password field appears when `needsPassword` is set (401 response without password, or incorrect password entered). Correctly appends `sc` to URL on success.
- `ViewContent.svelte`: If `sc` is present in URL, it pre-fills the password state. If metadata fetch returns 401, shows password panel. Correct.

### Minor Observations (non-blocking)
1. **Missing `loading = false` in `Home.svelte` success path**: After successful metadata fetch, `loading` is never reset to `false`. Because the component unmounts on navigation, this is not user-visible, but it is a logic gap.
2. **`MixedGallery.svelte` flag logic**: Combines executable (`64`) and dangerous (`128`) into a single `'dangerous'` branch. `ViewContent.svelte` separates them into `'executable'` / `'dangerous'`, but both map to `<ExecutableWarning>`, so behavior is identical.
3. **Chunk size warning**: Build emits a warning about `lib-BKGKj-wr.js` (~497 kB). This is from `marked` / `DOMPurify` and is cosmetic only.
