# CLI: embedding spaces

{% hint style="info" %}
**Outcome:** Create spaces, load JSONL vectors, upsert individual vectors, and run scoped vector search.
{% endhint %}

```bash
unitlab embeddings create "clip-vit-l14" --dimensions 768 --model-name ViT-L/14 --json
unitlab embeddings upload SPACE_ID embeddings.jsonl --json
unitlab embeddings upsert SPACE_ID ASSET_ID vector.json --frame-index 12 --json
unitlab embeddings search SPACE_ID query-vector.json --limit 25 --project-id PROJECT_ID --level frame --json
```

Each JSONL line must contain `asset_id` and `vector`; frame-level records may include `frame_index`. Empty files, malformed JSON, missing fields, dimension mismatches, and invalid search limits fail before or during the operation.

### Operating contract

| Concern           | Required behavior                                                           |
| ----------------- | --------------------------------------------------------------------------- |
| Execution surface | Pinned `unitlab==3.0.0` command in the intended Python 3.10+ environment.   |
| Machine contract  | Use `--json`; human-readable output is not an automation interface.         |
| Target resolution | Resolve stable IDs with a read command before a state-changing command.     |
| Success evidence  | Exit status, JSON result, returned IDs, and a read-after-write state check. |

### Failure and recovery boundary

| Condition                                       | Response                                                                                                     |
| ----------------------------------------------- | ------------------------------------------------------------------------------------------------------------ |
| Authentication or authorization fails           | Stop, correct the service identity or access model, rotate exposed credentials, and rerun a read-only check. |
| Validation or entitlement rejects the operation | Correct the input or entitlement; do not retry an unchanged request.                                         |
| A request times out                             | Inspect remote state before repeating a mutation because the server may have accepted it.                    |
| Asynchronous processing exceeds its deadline    | Preserve the Batch Queue or release ID, continue bounded monitoring, and inspect item-level failures.        |
| Only part of a batch succeeds                   | Keep successful identifiers, isolate failed rows, and retry only the corrected subset.                       |

{% hint style="warning" %}
Pin and test the production SDK version. Use stable IDs, keep secrets out of logs and command history, and record the correlation ID, target IDs, counts, final state, and redacted error details for material state changes.
