feat(api): update API spec from langfuse/langfuse 6a4314a

[langfuse-bot]

Greptile Summary

Updates the generated API client from the latest upstream specification.

• Adds session-ID filtering to synchronous and asynchronous observation-list APIs.
• Documents semantic-root filtering for metrics and evaluation rules.
• Updates blob-storage, comment-author, and SCIM password behavior documentation.
• Removes prior deprecation notices from v2 score retrieval methods.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete changed-code failure identified.

The only runtime change consistently wires an optional session filter through keyword-only public and raw clients, while the remaining changes update generated documentation without introducing a demonstrated contract or validation failure.

LGTM — auto-generated API client update from the Fern spec, purely additive and mechanical.

What was reviewed: the new session_id parameter on observations.get_many is wired through consistently in both sync/async client.py and raw_client.py (added to the params dict as sessionId, matching the existing pattern for user_id/userId). The boolean filter operator and isRootObservation docs additions on the unstable evaluation-rule filter types are documentation-only (the EvaluationRuleFilter_Boolean model already existed). The removed "deprecated" docstring blocks on scores.get_many/get_by_id and the reworded blob-storage/SCIM/comments docstrings are text-only changes with no code impact.

Extended reasoning...

Overview

This PR regenerates the Fern-based API client from an updated OpenAPI spec (langfuse/langfuse @ 6a4314a). All 16 changed files are auto-generated client/type files. The changes are: (1) docstring/description rewording for blob storage export source defaults, comment author constraints, and SCIM password field; (2) new documented isRootObservation dimension/filter examples for the metrics client (docs only, no new code path); (3) a new optional session_id parameter added to observations.get_many in both sync/async client and raw_client, forwarded as sessionId query param, following the exact existing pattern; (4) removal of stale "deprecated" docstring notices on two scores client methods; (5) documentation of the pre-existing boolean filter operator/isRootObservation column for the unstable evaluation-rule filter types (no new Pydantic model — EvaluationRuleFilter_Boolean already existed).

Security risks

None. No auth, crypto, or permission logic is touched. All changes are either docstrings or a new pass-through optional query parameter on a GET endpoint.

Level of scrutiny

Low. This is a generated-client update mirroring an upstream spec change, mechanically following established patterns (identical to how user_id/trace_id/etc. are already wired). No hand-written business logic, no control-flow changes.

Other factors

No CODEOWNERS-restricted paths are involved (these are auto-generated API client files, consistent with prior spec-sync PRs in this repo). The bug-hunting pass found nothing, and my own read of the diff found the new parameter correctly threaded through both the sync and async code paths.
