# Workspace

> How to read statuses, notes, and classifications when a document stops.

The invoice workspace is where you follow stamping day to day. Three signals matter:

1. **Status** — the label on the document right now
2. **Note** — observed values and what disagreed
3. **Classification ID** — the precise reason Lambda paused

## How to read a stopped document

1. Note the workspace label — [Statuses](/stamping/statuses).
2. Open the document note for observed values and the classification ID.
3. Match the ID to [Failures](/stamping/failures) or [System errors](/stamping/system-errors).

**Failed** can mean either a document/provider problem or a system/support problem. The note and classification ID distinguish them. Both appear under the same workspace label so you always open the note first.

When Lambda can safely continue stuck work, or when a deliberate correction is needed, continue with [Recovery](/stamping/retry/overview).
