Backport of BerriAI/litellm-private#5 (12981f93d3) onto stable/1.100.x, applied as
the PR's net diff so main-only intermediate refactors stay out.
The dashboard and lite CLI SSO specs under tests/e2e/ui/oidc are left out
because this line has no OIDC e2e harness to run them.
Adapted for stable/1.100.x: added Final to the test module's typing import; upstream's test file already imported it.
(cherry picked from commit 8a4fae0e17)
Adapted for stable/1.100.x: reflowed one generator to this line's ruff format (upstream reformatted it in a later style commit).

(cherry picked from commit daced81f20)
Adapted for stable/1.100.x: import-context conflict only (upstream's neighbouring custom_tools import is not on this line); the added and removed lines are identical to upstream.

Backport of #41607 to stable/1.100.x.
Cherry-picked from deb9d8aedd (main).

Backport of #42048 to stable/1.100.x.
Cherry-picked from 7966f50c34 (main). The safeguards backport maps the dangerous-tool-use-2026-09-03 beta for Bedrock, which Claude Opus 4.5 on Bedrock Invoke rejects as an invalid beta flag, so the all-beta-headers Bedrock cases run on Claude Fable 5.1 as they do on main.
The picked TypedDict fields use read-only Sequence[Mapping[str, object]] annotations and the picked Vertex test carries a test-quality-ok marker, so stable/1.100.x's LIT001, LIT012 and TQ008 budgets hold. Static typing only, no runtime change.
Hand-ported to stable/1.100.x from 47b2479c94 on main (fix(bedrock): gate Invoke tool search on the model map's supports_tool_search flag), the one prerequisite the #42288 handler tests need; the rest of that commit stays on main.
Backport of #42288 to stable/1.100.x.
Cherry-picked from merge commit fc82f6e8fa (litellm_safeguards_bedrock_vertex_messages).
The line has no bedrock_mantle beta-header mapping and no Mantle /v1/messages route, so the Mantle mapping, its test file, and the bedrock_mantle test parameter are left out.
Backports the Converse part of fbc6fb56ae from main (PR #31884). The gate only matched
openai.gpt-5, so a GPT-6 model fell through to Anthropic's thinking block and Bedrock
rejected the first real turn after a Claude Code /model switch with 400 Unknown
parameter: 'thinking'. The Nova 2 tool_choice registry keys and the invoke json_mode
forwarding in that commit stay on main
Backport of #41870 to stable/1.100.x. Cherry-picked from a6e3a72ed8 (main) with -m 1.
converse_transformation.py conflicted because this line has no `import re` and no
_is_openai_gpt_reasoning_model helper next to the insertion point. The resolution adds
exactly the four hunks #41870 merged: the import, the 16-token constant,
_requires_min_max_tokens, and the clamped maxTokens assignment. The test file applied clean.
Move the BaseLLMException import into _map_error_event_exception so the
module no longer imports it at load time, clearing the module-level cyclic
import CodeQL flagged. The class is used only on the cold error path.
Replace the mutable list-append test collector with aiter/anext so the
regression tests read the stream immutably.
(cherry picked from commit c246372859)
Mid-stream error events on the streaming Responses API were all raised as
APIError, so a content_policy_violation event never matched the router's
content-policy fallback dispatch and the client got the raw error instead
of the fallback model's answer. Map each error event's code and status
through the existing exception_type mapping, matching the non-streaming
path, and unwrap the typed ContentPolicyViolationError and
ContextWindowExceededError so the router routes them to the configured
content_policy_fallbacks and context_window_fallbacks.
