Long-running operations in Daneel — site crawls, vault indexing, knowledge graph builds — run in the background. You can close panels, switch tabs, and navigate freely without losing progress. The Settings > Tasks panel lets you monitor and control these operations.

## Open the task monitor

1. Click the Daneel widget icon to open the extension
2. Open **Settings** (gear icon)
3. Select **Tasks** in the sidebar (clock icon, between Data Backup and AI Models)

The panel shows two sections: **Active** tasks and **History**.

## Active tasks

Each running task shows:

- **Task name** — the site hostname or vault name
- **Task type** — Site Crawl, Vault Indexing, or Knowledge Graph
- **Progress bar** — percentage complete
- **Progress label** — current step (e.g., "Embedding page 12 of 50...")
- **Duration** — how long the task has been running
- **ETA** — estimated time remaining (extrapolated from current progress rate)

### Transport controls

Each active task has three icon buttons:

| Button | Action |
|--------|--------|
| **Pause** (two vertical bars) | Stops the task at its current checkpoint. The host tab releases resources. |
| **Resume** (play triangle) | Restarts a paused task from its last checkpoint. Skips already-completed work. |
| **Stop** (square) | Cancels the task permanently. Partial results (pages already crawled, documents already embedded) are kept. |
| **Delete** (trash) | Cancels the task (if active) and removes it from the list entirely. |

### Queued tasks

If you start a second task while one is already running, it shows as **"Waiting for GPU..."** with an amber dot. Daneel runs one GPU-heavy task at a time to prevent crashes. The queued task starts automatically when the current one finishes.

## History

Completed, failed, and cancelled tasks appear in the History section, sorted newest first. Each entry shows:

- Status (green dot for completed, red for failed, grey for cancelled)
- Task name and type
- Total duration
- How long ago it finished

Failed tasks include an error message you can use for troubleshooting.

### Clearing history

- **Clear all** — click "Clear all" next to the History heading to remove all history entries
- **Delete one** — click the trash icon on any individual history entry

History entries are also cleaned up automatically after 24 hours.

## Starting tasks

You don't start tasks from the Tasks panel — you start them from their respective UIs:

- **Site crawls** — open the Search overlay on any website, configure sitemaps and page limits, click "Start Crawl"
- **Vault indexing** — open the Vault panel, import files into a vault. Embedding starts automatically after conversion.
- **Knowledge graph builds** — open the Vault panel, scroll to the Knowledge Graph section, click "Build" or "Update"

Once started, all three task types appear in Settings > Tasks regardless of which panel triggered them.

## Recovering from interruptions

If the extension's service worker is evicted (Chrome routinely suspends inactive extension workers), or if you close and reopen Chrome entirely, tasks resume automatically within about 60 seconds. You may notice a brief pause in the progress bar, then it picks up where it left off.

For site crawls, already-crawled pages are not re-fetched. For knowledge graphs, already-processed chunks are detected via incremental mode and skipped.
