The deleted wrapper put cache: {"no-cache": true} on every request body, so the
gateway's response cache never answered a re-sent prompt. The SDKs send nothing
of the sort, and the mid-conversation prompt-cache priming loop re-sends an
identical body until the provider reports a warm cache, which a cached reply
never does. NO_PROXY_CACHE in sdk_clients.py restores the field as extra_body
on every messages, responses, completions, and embeddings call.
The wrapper also returned a 4xx as a value where the SDKs raise. The Bedrock
safety_identifier test judges the captured Converse body, and Claude on Bedrock
rejects the forwarded field with a 400, so the /v1/responses leg now suppresses
openai.BadRequestError the way the chat leg carries the same 400 as a Result.
The shared settings-store work this branch was stacked on landed on main,
along with source reporting for /config/field/info and /config/list.
Resolved by taking main for the store, the config routes and their tests,
and re-applying only the read surfaces main does not cover:
/alerting/settings, /get/ui_settings and /router/settings.
Claude Code's server-side auto-mode classifier sends a `safeguards` body field
together with the `dangerous-tool-use-2026-09-03` beta. PR #42152 made the
first-party anthropic route pass them through, but the beta header mapping
left the other two Claude platforms at null, so Bedrock Invoke dropped both
(classifier silently disabled) and Vertex forwarded the body field without
the beta, which the platform rejects with "safeguards: Extra inputs are not
permitted" (a 400 Claude Code hides by retrying without them).
Map the beta for bedrock and vertex_ai in the beta headers config and add
`safeguards` to the Bedrock Invoke request allowlist so the pair reaches
both platforms unchanged. Nothing is injected: a client that sends
`safeguards` without the beta still gets the platform's 400, exactly as
api.anthropic.com answers it.
A fallback hop that dies before its first chunk surfaces inside the streaming
iterator, where the chain lookup is keyed by the hop's own group. That group has
no chain of its own, so the remaining entries of the original list were never
tried. Resume the original group's chain as the last lookup key; attempted_targets
already skips the entries that were tried.
Resolves LIT-7400

Mantle serves anthropic.claude-haiku-4-5 without the dated -20251001-v1:0
suffix the Bedrock row carries, so the native route billed it at 0. Add a
bedrock_mantle/anthropic.claude-haiku-4-5 row and let a
bedrock_mantle/<region>/<model> name fall back to the region-free
bedrock_mantle/<model> row before the provider-prefixed lookup. Also
satisfy the mutable-collection gate in the native messages transformation.
Cherry-pick of merge commit b3882d8e43 (PRs #39321, #39562, #40107), which landed on litellm_internal_staging instead of main.
