* fix(router): resolve fallbacks against the tier a pre-routing hook selected
A complexity or auto router picks a tier behind the router group name, but
fallback lookup kept using kwargs["model"], which is still the router name. The
tier's configured chain never ran, so a provider failure on its first hop went
straight back to the client with "No fallback model group found for original
model_group=smart-router".
The hook assigns the selected model to a local only, and fallback resolution runs
on an outer kwargs dict that **kwargs already copied, so writing it there is not
visible. Record the selection in the metadata bucket instead, which is a nested
dict shared by reference across those copies and is how the router already
carries values back up, then key fallback lookup off it when present.
Applies to the generic, context-window, content-policy and weighted-failover
lookups. Reporting keeps using the router name, since that is what the caller
asked for.
Fixes#38832
* fix(router): annotate the recorded-selection helper with a read-only mapping
record_pre_routing_selection only reads the request kwargs, writing into the
nested metadata bucket it finds there, so Mapping states what it actually needs
and clears the LIT001 mutable-annotation budget without a suppression.
* test(router): assert the no-kwargs path leaks nothing
The tolerated-None case called the helper without checking anything, which the
test-quality gate counts as a test with no assertion. Assert that a fresh mapping
still reads back empty, so the case proves the call is a no-op rather than only
that it does not raise.
* fix(router): stop declaring loop-assigned locals Final in the selection helpers
Both helpers annotated a loop-assigned local as Final, which reassigns a Final on
every iteration and cost three basedpyright errors. Read the buckets through a
generator instead, so the write path iterates a for-target and the read path
resolves in one shot with next(), which also matches the functional style the
type-discipline rules ask for.
* style(router): apply ruff format to the selection helpers
* fix(router): derive the pre-routing tier fresh on every fallback hop
The metadata buckets also carry whatever the caller sent, so an inbound
pre_routing_selected_model let a client pick which fallback chain its
request fell into. A fallback hop also inherited the previous hop's tier,
so the second hop keyed its own failure off the tier that already failed
and never ran its own chain.
Clear the key at the top of async_function_with_fallbacks. Every hop
re-enters there, so only the hook that routed that hop can set it.
* fix(router): drop the cast at the fallback-hop clear call site
* feat(router): fall back on anthropic safeguard refusals on /v1/messages

The Guard main branch job ran while this PR still pointed at main and
recorded a failure that cannot clear: re-running it replays the original
event payload, base included. Its trigger is scoped to PRs against main, so
it does not apply now and a fresh head SHA is what drops the stale run.

`path:line` cannot represent a path that itself contains a colon, and the
one way pytest produces one is a Windows absolute location: separator
normalization turns `C:\app\e2e\a2a\test_x.py` into `C:/app/...`, which
slipped past the leading-slash check and composed the nonsense repo path
`tests/e2e/C:/app/e2e/a2a/test_x.py`.
Reject the colon itself rather than special-casing a drive letter: it is
the character the format reserves, so no path containing one was ever
linkable.

The JUnit report is the only thing that leaves the e2e run, and it says
where a test's results came from but never where its code lives. A reader
looking at `test_cell_claimed_only_by_a_skipped_test_is_uncovered` on the
status page has a name and nothing else -- no file, no line, no way to
reach the source short of grepping the repo by hand.
Pytest knows the location; the report format loses it. The `xunit1` family
wrote `file=` and `line=` onto every `<testcase>`, and the `xunit2` default
this suite runs on drops both. Switching families back would change the
document for every consumer of the same XML -- the Buildkite Test Engine
upload and the Loki pipeline included -- so add the location the way this
suite already adds `package` and `covers`: as a `<property>`, which is
purely additive.
`source` is repo-relative and one-based (`tests/e2e/a2a/test_x.py:41`), so
a consumer can build a link without knowing how pytest was started. That
takes normalizing the two launch shapes -- the runner image runs from its
own copy at /app/e2e, a developer runs from the repo root -- which is the
same normalization `package_from_nodeid` was already doing in reverse, now
factored into `suite_parts` so the two cannot drift apart. Paths that
escape the suite, and tests pytest reports no line for, emit an empty
string: a test with no link beats a link that 404s.

Clearing the Team combobox in the Create Key modal left team_id set to an
empty string, so /key/generate treated the request as team key generation
and failed with a team-not-found error for non-admin members.
TeamDropdown now emits null on clear, and GenerateKeyRequest normalizes an
empty team_id to None so the request runs the personal key path.
The text-completion wire test set litellm.aclient_session, which the
test-quality gate (TQ005) flags as a process-wide global write. Pass an
AsyncOpenAI client through the router's client kwarg instead, so the test
owns its transport and needs no cache flush or global restore.

* fix(cli): quote the Claude Code apiKeyHelper for cmd.exe on Windows
lite up and lite login --config-claude wrote the helper command with
POSIX shlex quoting, so a backslashed Windows install path came out
wrapped in single quotes that cmd.exe and PowerShell take literally.
Quote every token with the cmd.exe rules already used for agent shims
when running on Windows, and keep the POSIX output unchanged elsewhere.

trips for backslashed, spaced, metacharacter, percent and quoted tokens

Reading _target_order with .get left it in the request kwargs after selection, and only
nine provider boundaries stripped it. _atext_completion and _aadapter_completion spread
the raw kwargs, so an order-2 hop on /completions sent _target_order upstream, which
real providers reject as an unknown argument. Popping at selection strips it for every
path in one place; the PR's retry-keeping test already passed with pop because each retry
hands the callee its own kwargs copy.

Two P0 rows in the reliability coverage registry had no test.
reliability.retry.timeout.succeeds_within_retries gets a new file. The model
group is a pair: an always-timing-out deployment holding all of the group's
shuffle weight, and a healthy backup at weight 0. The weighted pick always opens
on the timing-out one, its first Timeout benches it via an allowed_fails_policy
of TimeoutErrorAllowedFails 0, and the retry falls through to the only
deployment left, so the outcome is a completion plus a reported retry with no
random first pick in the middle.
reliability.fallback.context_window.routes_to_fallback joins the existing
fallbacks spec. It registers a genuinely small-context OpenAI deployment, sends
a prompt past its limit so the provider refuses it on length, and reroutes with
context_window_fallbacks, which is the setting that handles that refusal rather
than plain fallbacks.
Both drive real provider calls through router_settings_override, so no config
change and no second proxy is needed. Reliability & Performance goes 16/36 to
18/36.

* fix(mcp): follow tools/list pagination from upstream servers
Adopts BerriAI/litellm#32244 by Jupiter363 onto litellm_internal_staging
with merge conflicts resolved
* fix(mcp): degrade buggy pagination to partial results and bound the preview walk
A repeated nextCursor now returns the tools collected so far instead of
discarding every page with a RuntimeError, an empty-string cursor is treated
as terminal, load_mcp_tools shares the same pagination walk instead of
returning only the first page, and the tools/list preview is bounded by the
listing timeout instead of only the per-request timeout times the page cap
* fix(mcp): annotate deliberate rebind for the preview timeout scope
* fix(mcp): bound the shared pagination walk with an overall listing deadline
The per-request session read timeout restarts on every page, so direct SDK
callers of list_tools and load_mcp_tools could run up to the page cap with
no overall bound. The walk now returns the tools collected so far when
max(MCP_CLIENT_TIMEOUT, MCP_TOOL_LISTING_TIMEOUT) expires
* fix(mcp): let a per-server timeout extend the pagination deadline
MCPClient carries a per-server timeout that can exceed the global default;
list_tools now passes max(self.timeout, MCP_TOOL_LISTING_TIMEOUT) into the
shared walk so a deliberately slow server is not silently truncated at the
global deadline
* fix(mcp): honor per-server timeouts in the preview deadline and test the walk sessionless
The preview deadline now extends with the created client's own timeout, and
the pagination walk's cap, repeated-cursor, and empty-cursor cases are tested
directly against the helper instead of through patched SDK internals
* fix(mcp): forward the preview request's per-server timeout to the temporary server model
The tools preview built its temporary MCPServer without the request's
timeout field, so the client factory always fell back to the global
default and a per-server timeout could never extend the preview's
listing deadline (or its per-request timeout).
