The hoisted structured row keeps every text block of the top-level system
prompt, empty ones included, while the scanned texts dropped the empty ones.
Guardrails that count one text per slot then came back with more texts than
the handler could place, so their rewrite was rejected. User text blocks were
already scanned empty or not; the system prompt now matches.
A mapped litellm_proxy exception now attaches an httpx.Response that
carries the proxy's response headers whenever the handler attached a
header-less synthetic one, on every status branch and on the relay
path. BadRequestError keeps its base-class contract: .headers stays the
proxy-supplied channel, so the proxy edge keeps forwarding an upstream
proxy's headers under the llm_provider- prefix and the date and server
edge change is no longer needed.
Only image-only unscoped content stays unrecorded; text or tool content
removed by scoping is recorded as not_run even when an image sits beside it.
Also keeps the type-discipline budget flat by returning the reason from the
helper and annotating the accumulator lists _extract_inputs requires.

main's test_one_text_per_row_over_a_system_prompt_is_rejected_by_name assumed the
top-level system prompt stays out of the scanned texts. This branch scans it, so one
text per structured row now lines up and the rewrite is applied; the test asserts that,
and a multi-block system prompt keeps the length-guard rejection covered.
The one-hour cache write fallback now takes the applied cache write rate, so an off-peak write price carries into it instead of the input rate
The cost estimate test for a cost-map model without cache prices now expects writes at the input rate, which is what the proxy bills
The recording logger in the deferred guardrail test types its callback parameters
The chat and A2A AgentCore handlers send X-Amzn-Bedrock-AgentCore-Runtime-User-Id
when runtimeUserId is set, and AWS requires bedrock-agentcore:InvokeAgentRuntimeForUser
alongside InvokeAgentRuntime on that call, so the ceiling now carries both. The role
identity policy still decides whether a given role may use it
The invalid-token test now uses a neutral example audience
A chat row whose content carried an empty text part counted two slots in the
chat completions handler while Prompt Security read one text out of the
modified row, so the structured rewrite was dropped and the request got the
named rejection. One shared helper now lists a row's slot texts and both the
slot count and the modified-row reader use it.
With a post-call guardrail the proxy defers async success logging, and every nested wrapper on a
/v1/messages call bridged to the Responses API overwrote the stored closure, so the spend log was
built from the outermost Anthropic-shaped reply under Responses semantics and recorded the prompt
tokens without the cache hit. The first wrapper to exit now keeps the slot, which is the innermost
provider response, the same one the non-deferred path logs.
The flat cost path also billed cache-creation tokens at 0 when the model had no
cache_creation_input_token_cost. It now falls back to the input rate, and the 1h rate to the
creation rate, matching the tiered path and the custom pricing helper.
The three guardrail translation handlers imported the exception from the proxy policy engine through a function-local import, which CodeQL flagged as a cyclic import. The exception and its helper now live next to the handlers in the shared guardrail translation utils, and the tests import it from there.
The Prompt Security modify-mode helper is also restructured into early-return TypedDict displays so the LIT002 budget stays at its limit
compress() scores text-only copies of the rows, so a content-part cache_control marker was gone by the time get_protected_indices ran and the pinned row could still be stubbed. Read protection from the original rows, which are index-aligned with the normalized copies, and add a regression test that fails without the change.
