CLI: embedding spaces

Create spaces, load JSONL vectors, upsert individual vectors, and run scoped vector search.

Outcome: Create spaces, load JSONL vectors, upsert individual vectors, and run scoped vector search.

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.

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.
