* fix(langfuse_otel): keep joined-trace tags, mask trace io, leave v2 trace io to the root

Joined traces (existing_trace_id) keep the caller tags they carried before,
and only the derived trace fields are skipped for them. mask_input and
mask_output now redact the derived trace input and output, matching the
vanilla Langfuse callback. The v2 mapper derives the trace name only,
because the root observation already carries the trace input and output
there. Uses the public preset cache key helper, moves imports to module
top, restores the original formatting of the unit test file, and adds
integration cells for the v2 llm_only scope and SDK sync/async calls.

* fix(langfuse_otel): split string caller tags the way Langfuse reads them

A caller tags value given as a comma list or a JSON array string (body
metadata.tags or the langfuse_tags header) used to reach Langfuse raw,
where ingestion split it into separate tags. Merging it with the derived
tags kept it as one tag, so parse it the same way before the merge

* test(otel): expect langfuse.trace.name on the v2 langfuse_otel generation span

* fix(langfuse_otel): read string mask flags the way the classic callback does

The langfuse_mask_input / langfuse_mask_output headers arrive as strings,
so "false" redacted the derived trace io. Parse them with str_to_bool and
fall back to truthiness, as the classic langfuse callback does

* fix(langfuse_otel): derive trace fields only on traces litellm starts

A litellm span that joins a trace an app or caller started (inbound
traceparent, the app's active span, a caller-provided parent span) no
longer gets a derived trace name, input, output or tags, like a request
joining an existing_trace_id. Langfuse applies the later-starting span's
trace update, so the derived values overwrote the app's own trace name
and io.

OTel v2 derives the name on the request root only when it has no parent,
and the generation span keeps main's caller-only trace name.

* test(langfuse_otel): keep main's OTel v2 generation key set in the arize family cell

The OTel v2 generation span no longer carries a derived langfuse.trace.name,
so the pinned key set goes back to main's.

* fix(langfuse_otel): name the OTel v2 request root once, from the request's own call

The v2 Langfuse logger re-derived langfuse.trace.name on the request root
for every LLM call in the request. A post_call llm_as_a_judge guardrail's
judge call replaced the caller's trace_name on the root with
litellm-acompletion, and with another v2 callback (otel, arize_phoenix)
listed before langfuse_otel that vendor's root span gained
langfuse.trace.name on every request.

The derived name now fills only an unnamed root this logger's provider
started, and never comes from a call litellm makes for its own features.
A caller trace_name still names the root on every call, as on main.

* fix(langfuse_otel): keep the derived trace fields from pushing other attributes off a full span

The derived trace name, tags, input and output were written after the OpenInference attributes with no room
check, so a span near the SDK's attribute limit (about 34 tools at the default 128) evicted keys main
exported, such as openinference.span.kind, metadata and llm.model_name, and raised the dropped count.
They are now written last and only into the room the limit leaves next to the error attributes a failed
call adds, so a full span exports what it would without them.

* test(langfuse_otel): give the full-span cells' derived request a caller trace id, as the joined one's traceparent does

* chore(langfuse_otel): drop the docstrings and comments the house rule disallows and type the new tests' parameters

* test(langfuse_otel): set the span attribute limit the full-span tests run at and keep Final locals out of the app-trace loop

In total litellm runs 1000+ tests

[02/20/2025] Update:

To make it easier to contribute and map what behavior is tested,

we've started mapping the litellm directory in tests/unit

This folder can only run mock tests.
