2. Cross-request cache collisions 🐞 Bug ⛨ Security
getCacheKey() collapses any non-string message content into the constant "[complex content]", creating cache-key collisions (especially for image/array content) and the module-scoped cache can serve cached results across requests/users.
Agent Prompt
### Issue description
`getCacheKey()` replaces all non-string `message.content` with a constant, causing cache collisions. Additionally, `queryCache` is module-scoped so cached data can be reused across requests/users.
### Issue Context
Resolution search and other flows use `CoreMessage['content']` arrays (e.g., text+image parts). Those currently hash to the same placeholder, making cached related queries incorrect and potentially cross-user.
### Fix Focus Areas
- lib/agents/query-suggestor.tsx[8-24]
- app/actions.tsx[75-90]
- app/actions.tsx[148-151]
### Suggested fix
- Scope cache to a chat/session identifier (e.g., add `chatId` param to `querySuggestor()` and use nested maps keyed by chatId), OR remove module-level caching.
- Improve keying:
- Serialize message content deterministically instead of substituting `"[complex content]"`.
- For array content, include the text parts and a stable placeholder for images (or a hash of sanitized content).
- Consider hashing the serialized key to limit memory usage.
- If safe keying/scoping can’t be guaranteed, disable caching when messages include non-string content.

3. Stale related stream output 🐞 Bug ≡ Correctness
Throttling can skip the last partial object update, and the stream is then completed without an unconditional final update, so the UI can render outdated related queries.
Agent Prompt
### Issue description
The throttling logic can prevent the last partial object from being sent to the UI stream.
### Issue Context
`finalRelatedQueries` is updated on every partial, but `objectStream.update()` is throttled and may not run for the last partial before `objectStream.done()`.
### Fix Focus Areas
- lib/agents/query-suggestor.tsx[66-83]
### Suggested fix
- After the `for await` loop, unconditionally call `objectStream.update(finalRelatedQueries)` (guarded if it has items), then call `objectStream.done()`.
- Optionally: initialize `lastUpdateTime = 0` so the first partial always updates, and use `>=` for the throttle comparison.
