**issue:** Mime type fallback may be unreliable for unknown extensions.

If neither mimeTypes.lookup nor response.headers['content-type'] returns a value, mimeType may be empty, which could cause issues later. Please add a default value to ensure mimeType is always set.

**suggestion (bug_risk):** Cache update logic for contacts may result in duplicate entries.

Review the handling of remoteJid and remoteJidAlt to prevent duplicate or inconsistent cache entries when updating with both contact types.

Suggested implementation:

```typescript
          if (contactRaw.remoteJid.includes('@s.whatsapp') || contactRaw.remoteJid.includes('@lid')) {
            const cacheRemoteJid = messageRaw.key.addressingMode === 'lid' ? messageRaw.key.remoteJidAlt : messageRaw.key.remoteJid;
            const cacheRemoteJidAlt = messageRaw.key.remoteJidAlt;

            // Check for existing cache entry for either remoteJid or remoteJidAlt
            const existingCacheEntry = await getWhatsappCacheEntry(cacheRemoteJid) || (cacheRemoteJidAlt ? await getWhatsappCacheEntry(cacheRemoteJidAlt) : null);

            if (existingCacheEntry) {
              // Merge or update the cache entry to ensure consistency
              await updateWhatsappCacheEntry({
                ...existingCacheEntry,
                remoteJid: cacheRemoteJid,
                remoteJidAlt: cacheRemoteJidAlt,
                lid: messageRaw.key.addressingMode === 'lid' ? 'lid' : null,
              });
            } else {
              // Add new cache entry if neither exists
              await saveOnWhatsappCache([
                {
                  remoteJid: cacheRemoteJid,
                  remoteJidAlt: cacheRemoteJidAlt,
                  lid: messageRaw.key.addressingMode === 'lid' ? 'lid' : null,
                },
              ]);
            }
          }

```

You will need to implement or ensure the existence of the following helper functions:
- `getWhatsappCacheEntry(remoteJid: string)` to retrieve a cache entry by remoteJid.
- `updateWhatsappCacheEntry(entry: object)` to update an existing cache entry.

If these functions do not exist, you should add them to your cache management module or service.

+    // TODO: Unificar verificação de cache para todos os números (normais e LID)
</code_context>

<issue_to_address>
**issue:** Multiple TODOs indicate incomplete refactoring and potential for missed edge cases.

The presence of TODOs for cache handling, particularly for LID numbers, suggests incomplete logic. Please address these to avoid missing edge cases.

**suggestion (code-quality):** Prefer object destructuring when accessing and using properties. ([`use-object-destructuring`](https://docs.sourcery.ai/Reference/Rules-and-In-Line-Suggestions/TypeScript/Default-Rules/use-object-destructuring))

```suggestion
    const {remoteJid} = body.key;
```

<br/><details><summary>Explanation</summary>Object destructuring can often remove an unnecessary temporary reference, as well as making your code more succinct.

**suggestion (code-quality):** Avoid unneeded ternary statements ([`simplify-ternary`](https://docs.sourcery.ai/Reference/Rules-and-In-Line-Suggestions/TypeScript/Default-Rules/simplify-ternary))

```suggestion
              content = bodyMessage || '';
```

<br/><details><summary>Explanation</summary>It is possible to simplify certain ternary statements into either use of an `||` or `!`.
This makes the code easier to read, since there is no conditional logic.

      if (altJid) {
        if (!finalJidOptions.includes(altJid)) {

**suggestion (code-quality):** Merge nested if conditions ([`merge-nested-ifs`](https://docs.sourcery.ai/Reference/Rules-and-In-Line-Suggestions/TypeScript/Default-Rules/merge-nested-ifs))

```suggestion
      if (altJid && !finalJidOptions.includes(altJid)) {
            finalJidOptions.push(altJid);
      }

```

<br/><details><summary>Explanation</summary>Reading deeply nested conditional code is confusing, since you have to keep track of which
conditions relate to which levels. We therefore strive to reduce nesting where
possible, and the situation where two `if` conditions can be combined using
`and` is an easy win.
