Python SDK v6.2.0

Added

• client.signals.create, client.signals.update, and client.signals.delete on LatitudeApiClient and AsyncLatitudeApiClient — author signals over the API. create registers a signal with its own evaluation (declarative settings, e.g. an LLM judge with criteria, or a raw script) plus optional priority and filters; update changes a signal's name, description, and filters; delete removes a user-authored signal. Adds the CreateSignalResponse and UpdateSignalResponse types.

Changed

• Evaluation.alignment and Evaluation.aligned_at are now optional — they are omitted for raw or deterministic evaluations that are not annotation-aligned.
