feat(api): update API spec from langfuse/langfuse ce4a1e9

[langfuse-bot]

Confidence Score: 4/5

The PR should not merge until compatibility for the removed public SDK-log imports is addressed.

Summary

This generated API update adds comment and observation timestamp hints, prompt-list filtering, shared cursor metadata, and revised ingestion and real-time API guidance.

• The removal of public SDK-log types breaks existing imports.
• The new OTLP guidance incorrectly claims the Python SDK already sends the specified ingestion-version header.

Looks good — this is a mechanical, auto-generated Fern API client sync with no bugs found.

What was reviewed: the new shared CursorMetaResponse pagination base class and its wiring through langfuse/api/utils/pagination lazy-import maps; the refactor of ExperimentsResponseMeta, ObservationsV2Meta, GetScoresV3Meta, and CursorMeta to inherit from it instead of duplicating the cursor field; and the removal of the sdk-log ingestion event type (SdkLogEvent/SdkLogBody), confirmed unused elsewhere in the SDK. All changed files carry the Fern auto-generation header and match the described upstream spec bump.

Extended reasoning...

The diff is entirely within langfuse/api/ (Fern-generated client code): a new CursorMetaResponse pagination type, several resource meta types refactored to inherit from it, deprecation-notice docstrings and a new deprecation field on IngestionResponse, and removal of the sdk-log ingestion event type. No security-sensitive surface (auth, crypto, permissions) is touched, and the sdk-log type removal was verified unused elsewhere in the repo. Given the small, mechanical, spec-driven nature of the change and no CODEOWNERS or outstanding review objections, this is safe to approve.

Public SDK-log imports break

Callers that import SdkLogBody, SdkLogEvent, or IngestionEvent_SdkLog to construct sdk-log batches now get an ImportError because those public exports were removed. This takes effect before the documented November 16, 2026 Cloud cutoff and also affects self-hosted callers. Please retain compatibility for these imports while those callers are supported.

**Public SDK-log imports break**

Callers that import `SdkLogBody`, `SdkLogEvent`, or `IngestionEvent_SdkLog` to construct `sdk-log` batches now get an `ImportError` because those public exports were removed. This takes effect before the documented November 16, 2026 Cloud cutoff and also affects self-hosted callers. Please retain compatibility for these imports while those callers are supported.
