# RetrieX SSE running reconnect / final cleanup fix

Patch-only fix for the streamed answer UI after the job-based SSE flow.

## Problem

After introducing stream jobs, an EventSource reconnect to an already running job could receive:

```text
retry: 15000

: duplicate-or-finished-stream

event: done
data: [DONE]
```

Because `running` jobs were treated like harmless duplicate/finished streams, the browser could finalize an incomplete answer as if it had completed successfully. In addition, the final `done` cleanup still used the streaming cleanup path, which can keep the last `.think` block visible.

## Changes

- `running` duplicate/reconnect streams are no longer silently closed as successful `[DONE]` completions.
- Only already `completed` duplicate streams are silently closed with `done`.
- A reconnect to a still-running job now follows the existing explicit error path, so the UI can show a clear interruption message instead of silently accepting a partial answer.
- Final stream completion now removes all `.think` blocks and the loader class.

## Changed files

- `src/Controller/AskSseController.php`
- `public/assets/js/base.js`

## After installing

Run:

```bash
php bin/console cache:clear
php bin/console mto:agent:config:validate
php bin/console mto:agent:regression:test
```

Also hard-refresh the browser or clear browser cache because `public/assets/js/base.js` is client-side JavaScript.
