fix(images): honor max_retries and prevent Router retry amplification (#48705)
* test(images): cover SDK retry budgets and router ownership

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(images): forward max_retries to the OpenAI image generation client

Per-call, deployment and default_litellm_params max_retries were filtered
out before reaching the OpenAI-compatible image handler, which then always
used 2 SDK retries. Forward the caller's value, and pin it to 0 for routed
calls so the Router stays the only retry owner, matching completion()

test(scim): audit #47544 (#48791)
* test(scim): audit #47544

Add integration cells for the SCIM group delete that now runs through the team delete's bulk path: an admin group delete revokes its members' admin key, a delete sent with the IdP's SCIM token revokes member keys and audits them under that token, a delete that times out on a locked member row changes nothing so a retry works, and two racing team deletes write one tombstone and one team audit row

* test(scim): read the racing team delete's audit rows after the proxy drains them

Covers the json_schema envelope edge cases #47478 fixed on the Anthropic json tool path: a key listed only in
`required`, a tool-named wrapper on a stream, non-ASCII and lone-surrogate answers, a stream cut before the tool
block closes (proxy and sync SDK, Anthropic and Bedrock Invoke), and a string `output_format` with and without
`drop_params` on Anthropic and Vertex chat and /v1/messages. The scripted Anthropic peer now refuses a non-object
`output_format` the way Anthropic does

test(proxy): pin the max_parallel_requests slot release when a streamed /v1/messages MCP auto-execute ends (#47788)
* test(proxy): cover the max_parallel_requests slot a streamed /v1/messages MCP auto-execute keeps

A streamed /v1/messages request that auto-executes MCP tools replays its answer
as a stream after its model rounds already logged success. The stream path frees
the request's max_parallel_requests slot only on a client disconnect, so after
message_stop the slot stays taken and the key's next request answers 429

The test streams such a replay to the end and expects the slot to be free. It
fails until the fix lands

* fix(proxy): free the max_parallel_requests slot when a replayed /v1/messages MCP stream completes

A streamed /v1/messages request that auto-executes MCP tools runs its model
rounds without streaming and replays the final answer as a stream. The first
round claims the request's only success log, and its limiter callback keeps the
slot because the tool call reused it afterwards. The stream path released the
slot only on a client disconnect, so after message_stop the key stayed at its
max_parallel_requests limit and its next request answered 429

Stream cleanup now releases the stashed slot when the stream completed and its
logging object already claimed the success log, which only happens when the
stream replays a response that was logged before it started. A real stream
still releases through its own success callback

* test(mcp): free the key's only parallel slot after a streamed auto-execute ends

Run a streamed MCP auto-execute on a key with max_parallel_requests 1 on
every LLM surface, then send the next request on that key and expect 200.
On main both /v1/messages surfaces answer 429 here, while /v1/responses and
/v1/chat/completions already pass

* test(proxy): keep only the MCP stream regression tests, since #48628 already frees the slot at stream end

* test(proxy): require the MCP stream regression test's response to stream and reach its end event

* fix(langfuse otel): share request metadata export across callbacks

* fix(langfuse otel): drop prompt variables, MCP tool I/O and vector store queries from exported request metadata

* fix(langfuse_otel): keep span export alive when nested request metadata has non-string keys

The content strip validated prompt_management_metadata, mcp_tool_call_metadata
and vector_store_request_metadata items as str-keyed mappings, so an SDK
caller passing one with a non-string key raised inside
exported_request_metadata: OTEL v2 dropped the LLM span for every vendor and
v1 langfuse_otel lost the request metadata and every attribute after it.
Validate those nested mappings with object keys instead. Also hoists the
langfuse_otel imports.

* fix(langfuse_otel): send the request metadata blob to Langfuse destinations only

- A requester_metadata that is not a mapping no longer raises. The v2 LLM span
  (every vendor) and the v1 Langfuse attributes survive it again.
- Prompt-quoting routing_decision fields stay out of langfuse.observation.metadata.
- An exporter or key/team destination for any other backend drops
  langfuse.observation.metadata and langfuse.trace.metadata.user_api_key_*, as on
  main. This covers a collector folded into the Langfuse logger.
- The v2 Langfuse key-set pin in the arize family test gains the two new keys.

* fix(langfuse_otel): export only caller identity under the Langfuse metadata keys

- The Langfuse metadata keys carried the whole request metadata. On OTel v2 that
  sent request headers, caller metadata, user email, user agent and auth metadata
  to a Langfuse destination that never received them on main; on v1 it doubled
  each span's metadata payload, so big caller metadata doubled the export size
- Both paths now export only the key alias, user, end user, team, team alias and
  org. On v2 that is the team plus the identity among the operator's
  `baggage_metadata_keys`, which v2 spans already carry as `litellm.metadata.*`.
  Everything else stays in the bare `metadata` attribute, as on main
- `output_messages` returns a list again, and the arize v2 b3 key pin is back to
  main's set

* fix(langfuse_otel): drop the caller identity first when a span hits its attribute limit

v1 wrote the identity attributes after the OpenInference ones, so a span near the
128-attribute limit (about 33+ tools) evicted openinference.span.kind, metadata
and llm.model_name instead. The identity now goes first on a fresh span, so the
SDK evicts it before anything else, and a caller's active span that already
carries attributes does not get it.

v2 sheds the Langfuse identity keys before any indexed message attribute when a
span is over budget, so a span keeps every attribute it carried without them.

* fix(langfuse_otel): keep other spans and dropped counts as main exports them

- v1 writes the caller identity only into the room the span's attribute
  limit leaves next to the error attributes a failed call adds, so the
  exported dropped-attribute count matches main
- v2 strips the Langfuse request metadata only from LiteLLM's own spans;
  application, instrumentation and server spans keep every key they set
- a stripped v2 span keeps the dropped attribute, event and link counts
- a config that lists the Langfuse mapper without the langfuse_otel
  exporter also keeps the request metadata away from other exporters

* fix(langfuse_otel): keep the caller identity off the caller's active span

v1 writes LiteLLM's attributes onto the caller's active span when one is
current instead of starting its own span. That span goes to the caller's
own exporter, so the identity keys reached a non-Langfuse collector and
could take attribute slots the caller fills later. The identity keys now
go only on the span LiteLLM starts, whatever the caller's span carries.

* fix(langfuse otel): keep the identity keys on the OTEL v2 Langfuse mapper only

The v1 langfuse_otel callback goes back to main: it sends no
langfuse.observation.metadata or langfuse.trace.metadata.user_api_key_*
keys. The OTEL v2 Langfuse mapper keeps them. The integration cells now
run every endpoint, client, redaction, failure and chaos case on v2.

* test(langfuse otel): count only accepted batches in the sink outage cell

The wire also records the batches the sink answered 503, so an exporter
retry made a span look exported twice. The chaos cells now also check the
spans that landed carry the caller identity.

* test(langfuse otel): split stacked span comprehensions and drop constant comments

* test(langfuse otel): split the metadata integration module into focused files

* fix(langfuse otel): send the org id in trace metadata too

The trace metadata keys now reuse IDENTITY_METADATA_FIELDS, so a key in an org gets langfuse.trace.metadata.user_api_key_org_id next to the generation's org id.

* fix(tavily): return raw_content, score, favicon and the response envelope from Tavily search

Tavily search dropped every field except title, url and content, so
include_raw_content, include_answer, include_images and include_favicon
reached Tavily but their output never reached the caller. Each result now
carries raw_content, score and favicon when Tavily returned them, and the
top-level fields (answer, images, request_id, usage, ...) come back as
provider_metadata, same as the Exa fix in #47423

feat(passthrough): let upstreams report the model name via x-litellm-upstream-model (#48275)
* feat(passthrough): let upstreams report the model name via x-litellm-upstream-model

A pass-through upstream that prices its own requests already reports cost and
tokens in x-litellm-response-cost / x-litellm-total-tokens. Product endpoints
that take no `model` in the body still landed under `unknown`, so their spend
could not be broken down.

When the upstream sends x-litellm-upstream-model, record its value as the
request's model on success and failure rows, overriding any body `model`. The
name is a label only: it never marks the request as upstream-priced and is not
used to look up a price. A blank or missing header changes nothing.

Refs LIT-9910

* fix(passthrough): keep the upstream-reported model name bounded

The upstream model name becomes a spend row, a daily rollup key and a metric
label. Use only the first element of a repeated header (RFC 9110 field
combining, which is how httpx joins it) and cut the name to
MAX_SPEND_LOG_MODEL_NAME_LENGTH, the limit the spend log already applies to
model names.

Refs LIT-9910

* test(passthrough): cover x-litellm-upstream-model through spend rows and rollups

Drives a config-defined pass-through against a scripted upstream and reads
back the spend row, the daily team rollup and /team/daily/activity. Covers the
header winning over a body model on buffered and streamed responses, failure
rows, a model-only header keeping cost_per_request, the no-header and blank
header cases, and repeated or long header values.

test: update stale integration and guardrail e2e tests to intended behavior (#48665)
* test(integration): update stale expectations to intended provider behavior

Each expectation moved because a merged PR changed behavior on purpose.
- chatgpt string input is wrapped as one user message (#41522)
- Gemini 2.5 tool media sits beside function_response (#48428)
- sampling knobs move to Gemini 3.5 Flash, which keeps them (#47645)

- ai_decide answers without usage return usage null (#48261)
- azure_ai forwards mapped client anthropic-beta values (#48033)
- the OpenCode scripted upstream mints a fresh id per request

* test(e2e-ui): type the guardrail name before deleting it

GuardrailDeleteModal requires the exact name before Delete enables since
#45893. All three guardrail delete flows now go through one helper.

* test(observability): accept any sampled traceresponse flags and expect a 400 for a non-object body

OpenTelemetry 1.45 (#48055) sets the W3C random trace id flag on new traces,
so the gateway's traceresponse now ends in -03. The producer copies the server
span's own trace flags, so the tests now accept any two-digit flags with the
sampled bit set instead of pinning -01

#48438 made a non-object JSON body a 400 "Invalid JSON payload: expected an
object" on purpose, so the [1] body case is renamed non_object_body and
expects that 400

* test(observability): stop waiting on OpenTelemetry's export log line in the langtrace outage test

The outage test waited for "Exception while exporting Span batch" in the proxy
log, which is OpenTelemetry's wording and no longer appears with 1.45. The test
keeps asserting what the gateway guarantees, callers unaffected during the
outage, a live gateway, and every span after recovery delivered once with no
outage span duplicated

* test(guardrails): count the Responses disconnect spend rows #47611 added

Since #47611 a streamed /v1/responses disconnect writes its own spend row, so
the concurrent disconnect test saw 20 rows where it counted 10 by model group.
It now reads each row's call type and expects ten acompletion rows with the
outage verdict and ten aresponses rows with success. /v1/messages disconnects
still write no row on main, so they are left out of the count rather than
pinned as absent

The responses-httpx case of the single disconnect test no longer needs its
LIT-8603 skip and passes

* test(observability): size K4's timeout from the harness boot budget

K4 boots three two-worker proxies in a row. On CircleCI each boot takes 43 to
58 seconds, so a passing run took 179.97s against its fixed 180s cap and 6 of
30 runs hit pytest-timeout. The cap and the restart gate wait now come from
readiness_seconds and graceful_stop_seconds, like other multi-boot tests

fix(guardrails)!: redact secrets in tool traffic and system prompts (#47122)
* fix(guardrails): redact secrets in tool traffic and Anthropic system

* fix(guardrails): bound tool payload scans and stop nested tool_result recursion

Scan each tool value beside its key instead of an indented dump, read
tool_result content one level deep, keep non-finite tool arguments as
raw text, and give read-only guardrails one fragment per tool payload

* test(guardrails): cover read-only guardrail consumers of tool and system text

* fix(guardrails): keep tool argument parsing, scanning and tests within bounds

Treat tool arguments that decode to a lone surrogate as raw text, decode
JSON-escaped detections back to the leaf value, quote unkeyed leaves
without repeating a parent key per list item, drop cycle tracking that
parsed JSON cannot reach, and use the CI license instead of a fake
license server

* fix(guardrails): scan list items beside a capped parent key

List items keep their parent key in the scanned JSON line, capped to its
last 64 characters, so a credential key over a list is still detected
while a long key over many items no longer multiplies the scan text

* fix(guardrails): cap the scanned key after JSON escaping

A key of control characters escaped to six times its length after the
cap, so every list item's scan line grew with it

* fix(guardrails): collapse whitespace in the scanned key context

Space-heavy keys made every inherited list item scan several times slower
than a short key

* fix(guardrails): build each key's scan context once per payload

Repeating the collapse, escape and cut for every list item made a long key
over many items cost key length times item count

* fix(guardrails): cover Responses tool call items and instructions

Responses carries the same tool call arguments and system prompt as chat
and messages under function_call.arguments, custom_tool_call.input and
instructions, so secrets there reached the provider unscanned

* perf(guardrails): skip rescanning text hide-secrets already found clean

Agents resend their whole conversation on every turn, so each turn
rescanned every earlier tool result. Each guardrail now keeps a bounded
set of digests of scan inputs that held no secret and skips those; text
with a secret is always rescanned and no secret material is kept

* fix(guardrails): size the clean-scan cache for many sessions and replace longest secrets first

4096 digests held about 20 long agent sessions per worker, so interleaved
sessions evicted each other and every resend rescanned its history;
65536 digests (about 10 MB) hold a few hundred. Tool payload secrets are
now replaced longest first after JSON unescaping, so a shorter overlapping
match cannot leave part of a secret behind. The key-context test checks
the work it bounds instead of wall-clock time, which CI could not meet

* fix(guardrails): keep unmasked tool argument text and redact keyword matches cut inside an escape

* fix(guardrails): write a tool visitor's whole payload when it changes more than string values

* fix(guardrails): read message text before tool and system text so a vendor error on the new text cannot skip it

* fix(guardrails): moderate tool and system text in its own call so a long payload cannot hide a flagged message

* fix(guardrails): skip the empty moderation call when only tool or system text is present

* fix(guardrails): scan long multi-line tool strings as their own lines so the scan stays linear

* fix(guardrails): keep the key beside every line of a long multi-line tool string

* fix(guardrails): confine tool-traffic coverage to hide-secrets

Restore iter_message_text to its main behavior, so banned keywords, Azure
Content Safety, IBM detectors and the OpenAI and Google moderation hooks
read exactly what they read on main. Only walk_user_text, which
hide-secrets alone calls, still reaches system, instructions and tool
payloads.

* test(guardrails): stop the tool-traffic integration tests from flaking on a busy host

Use the shared per-case timeout for the rig client, and open a new
connection per call in the worker-kill burst so a pooled keep-alive
socket to the killed worker is never reused.

* test(guardrails): drop the wall-clock check from the deep tool arguments unit test

The integration test test_deeply_nested_tool_arguments_do_not_stall_the_worker
already covers the timing; the unit test keeps the redaction check.

fix(proxy): keep every startup line JSON when json_logs is on (#47035)
* fix(proxy): keep every startup line JSON when json_logs is on

Boot-time messages the proxy printed straight to stdout (banner, feedback
box, model list, cache and callback notices, policy table, migration
notices, CLI launch notes) and the first records of uvicorn- or
granian-spawned workers came out as plain text while json_logs was on,
breaking log pipelines that parse every line as JSON.

- print_startup_message() prints unchanged in plain mode and, with
  json_logs on, emits one INFO record on the proxy logger (ANSI
  stripped) that skips the logger and handler level checks like the
  print it replaces; show_banner() routes to it in JSON mode only
- the CLI exports JSON_LOGS=true when the config sets json_logs so
  spawned workers log JSON from their first record
- the --enforce_prisma_migration_check deprecation notice prints after
  the config is read so a config-only json_logs covers it

Resolves LIT-1624

* fix(proxy): keep show_banner() SDK-free, pick the JSON banner in initialize()

Since #46803 the `lite` shell calls show_banner() against an uninitialized
litellm package, and reading litellm.json_logs inside it initialized the whole
SDK at the banner (0.14 s to 0.83 s for a bare `lite` here, the seconds that PR
removed on small VMs). show_banner() is back to its main version; the proxy's
initialize() now emits the JSON banner record itself and calls show_banner()
only in plain mode. The banner unit tests move to the initialize() call site.

* fix(proxy): keep the JSON banner when an operator --log_config names the proxy logger

uvicorn applies --log_config after proxy_cli has switched JSON logging on and before
initialize() switches it on again through load_config(). A logging config that names
"LiteLLM Proxy" removes that logger's handlers in the window between the two, which is where
initialize() emits the banner and the feedback box, so at one worker both went nowhere;
two-worker children import litellm after uvicorn's logging setup and were not affected.
print_startup_message() now falls back to a one-off JSON handler, on the stream the JSON
handler uses, when the proxy logger has no handler of its own.

Live, json_logs on plus a log_config naming the proxy logger, one worker: main prints the
banner and the feedback box as plaintext, e2303a3925 prints neither, this head prints both as
one JSON record each. New unit test fails on e2303a3925; new integration cell
test_json_logs_with_operator_log_config_keeps_every_line_json passes at one and two workers.

* fix(proxy): keep a long startup listing whole in its JSON record

print_startup_message ran its record through the proxy logger's filters, so
in JSON mode the required-migration SQL list and the policy list were
middle-truncated at MAX_STRING_LENGTH_STDOUT_LOG (4096 by default) with the
litellm_truncated marker, where the prints they replace showed them whole.
That cap bounds echoed request payloads; a startup message is operator text,
so the record now gets the uncapped processing of a DEBUG line: secret
redaction and base64 collapse still apply, the text cap does not.

Red on 41f92b745a, green here:
- tests/unit/test_logging.py: a listing longer than the cap comes out whole;
  a credential in a startup message is still redacted
- tests/integration/configuration/test_json_logs_startup.py: a 60-policy
  config boots with json_logs on and the policy listing record (9762 chars)
  carries every policy with no truncation marker (4096 chars, marker, on
  the unfixed tree)

* fix(proxy): keep the --enforce_prisma_migration_check notice on --health and --test

This PR moved the deprecation notice after the config is read, so that a
json_logs set only in the config applies to it; --health and --test return
before that point and stopped printing it, a visible change main did not
have. The notice is now also emitted before those two returns, through the
same helper, so a deployment running `litellm --health
--enforce_prisma_migration_check` still learns the flag is dead, as on main.
A normal server start emits it once, after the config, as in the previous
commit.

Red on 2d7a2d6844, green here: tests/unit/proxy/test_proxy_cli.py asserts
the notice on --health and on --test.

* fix(proxy): keep the JSON startup records on stdout under an operator handler on the proxy logger

An operator --log_config that gives "LiteLLM Proxy" a handler of its own, a NullHandler
that silences it or a plain WARNING-level handler on stderr, is in force in the window
where the banner, the feedback box and the cache notice are emitted: uvicorn applies it
after the CLI process switched JSON on and before initialize() re-installs the JSON
handler through load_config(). 41f92b745a sent the startup records through the proxy
logger's handlers and fell back to a JSON stdout handler only when there were none, so
under such a config the records landed in the operator's handler, as plaintext on stderr,
or vanished, where the prints they replace reached stdout whatever the logging config
said.

print_startup_message() now writes every startup record through the proxy's own JSON
handler on stdout, filters included, and never through the proxy logger's handlers; the
operator's handler gets nothing from a startup message, as it got nothing from the print.
The normal JSON handler is the same class, formatter and filters, so the records a
pipeline reads are unchanged when no operator config is in play.

Tests: tests/unit/test_logging.py gets the two handler shapes (red on f6f5957d16: the
record went to stderr as plaintext or nowhere); tests/integration/configuration/
test_json_logs_startup.py gets a silencing operator --log_config cell at 1 and 2 workers
(red on f6f5957d16: banner, feedback box and cache notice missing; green here).

* fix(proxy): print the --enforce_prisma_migration_check notice when the config fails to load

f6f5957d16 printed the deprecation notice after the config is read, so a json_logs set
only in the config makes it a JSON record. A boot whose config file is missing or does
not parse then exited before that point and never printed it, where main printed it
before the error (10-20 gauntlet finding).

The notice is printed where main printed it, unless a config file can still switch
json_logs on: then it is held until the config is read and printed right after the
json_logs switch, and a click close callback prints it on the way out if the boot fails
first. functools.cache keeps it to one print either way.

Tests: tests/unit/proxy/test_proxy_cli.py covers a failed config read (red on
75043aed83), a plain config printing it once and a config-only json_logs making it one
JSON record; tests/integration/configuration/test_json_logs_startup.py adds the JSON cell
and a missing and an unparseable config cell (red on 75043aed83, green here), through
refused_boot_log, which now takes extra CLI arguments.

* fix(proxy): keep startup records as printed instead of running secret redaction

In JSON mode the startup messages ran secret redaction, which the prints they replace never
had. Its sk- key pattern has no left boundary, so a model named risk-assessment-gpt4o was
logged as riREDACTED in the model list (10-21 gauntlet finding). The records now skip
redaction like the prints did; the processed record still counts as scrubbed, so the
handler's secret filter and the formatter leave it alone. The stdout cap stays off and base64
collapse stays on, as before.

Tests: tests/unit/test_logging.py checks the model name comes out whole (red on 7d17f126e5),
replacing the test that asserted startup records were redacted;
tests/integration/configuration/test_json_logs_startup.py adds a boot with a
risk-assessment-<id> model whose model list record carries the name (red on 7d17f126e5).

* refactor(proxy): meet the AGENTS.md rules Greptile flagged on the startup-message change

The policy listing builds its rows as tuples in two helpers instead of appending to a list;
plain output is unchanged (same bytes as before across 3000 random policy and attachment
configs). The explanatory comments added with this change are gone, and the docstring of
print_startup_message now says the record is whole and unredacted.

Tests: the migration-diff JSON test no longer runs the fake prisma CLI; it checks the
skipped-diff notice in-process, and the fixture extension it needed is reverted. The
json_logs export and deprecation-notice CLI tests run the real proxy module and a real
config file instead of a mocked ProxyConfig and proxy module, and the --health/--test
notice tests no longer patch our helpers. Each still fails when the export, the hold or
call_on_close is removed. New test parameters are typed.

fix(aiohttp_transport): close an owned aiohttp session when its transport is collected (#48650)
An OpenAI or Azure SDK client litellm built and evicted from the client
cache is usually garbage collected inside the closer's 900 second grace
window, so the closer's weak reference dies and the client's aiohttp
session is never closed. LiteLLMAiohttpTransport.__del__ now hands an
owned, still-open ClientSession to _close_recycled_session, which already
covers the current-loop, foreign-loop and closed-loop cases.

* feat(proxy): size the whole btree entry in the row check and name the flag for what it does

The index check now lays out each row's entry the way index_form_tuple does (tuple header, null bitmap, every indexed column at its alignment, rounded to 8) and compares it with BTMaxItemSize for the server's block_size, so a key that passes octet_length > 2704 but still fails the (api_key, startTime) index is caught. --db_preflight becomes --check_migrations_against_existing_data, db_preflight.py becomes migration_data_checks.py and the timeout env var LITELLM_MIGRATION_DATA_CHECK_TIMEOUT

refactor(mcp): drop the experimental label from the MCP server and client paths (#48513)
* refactor(mcp): drop the experimental label from the MCP server and client paths

Move litellm/proxy/_experimental/mcp_server to litellm/proxy/mcp_server and litellm/experimental_mcp_client to litellm/mcp_client, with the mirrored tests moved under tests/unit/proxy/mcp_server and tests/unit/mcp_client. Both old packages stay as shims that warn with DeprecationWarning, re-export the new package's public names and alias every submodule in sys.modules so deep imports keep resolving to the same objects. The OpenAPI docs gate now puts the merge base's enterprise package on PYTHONPATH so its base counts do not mix the checked-out enterprise code with the base litellm tree

* fix(mcp): alias namespace subpackages and bind attributes in the deprecated MCP shims

pkgutil.walk_packages skipped mcp_server/auth because it has no __init__.py, so old imports of litellm.proxy._experimental.mcp_server.auth.* failed, and sys.modules entries alone left litellm.experimental_mcp_client.tools unreachable as an attribute. Walk the package on disk and setattr each alias on its old parent.

* 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

refactor(anthropic): rename llms/anthropic/pass_through to llms/anthropic/messages (#48510)
* refactor(anthropic): rename llms/anthropic/pass_through to llms/anthropic/messages

Move the unified /v1/messages code out of a directory called pass_through, since it is not the
passthrough feature. The inner messages sub-package becomes native, and the Vertex AI partner
model experimental_pass_through package becomes messages. The old packages stay as import shims
that warn once and alias every submodule in sys.modules, so old deep imports still resolve
