* feat(anthropic): generate auto mode safeguard_results with a classifier model on the /v1/messages chat bridge
* fix(anthropic): check caller limits for the safeguards classifier, mark truncated tool calls, and keep pre-compaction context
* fix(anthropic): log classifier spend under the caller's key hash and read list-shaped classifier replies
* feat(anthropic): generate safeguard_results on the Responses bridge and native non-Claude /v1/messages providers
* fix(messages): keep safeguards requests on Python under the Rust opt-in
* fix(anthropic): keep non-ASCII text unescaped in the safeguards classifier prompt
* test(anthropic): build the text-parts classifier reply without openai's construct path
Message.model_construct goes through openai's construct_type, which caches
discriminated unions in a weak-key map. On Python 3.12 a PEP 604 union cannot be
weak-referenced, so the fixture raised inside the fake classifier and the test
read an unavailable verdict. model_copy sets the list content without that path.
* fix(anthropic): scan only new bytes for SSE frame ends on safeguarded native streams
* fix(anthropic): answer safeguards on web search short circuits and widen the classifier reply cap
* fix(anthropic): answer unsupported when the proxy serves no deployment for the safeguards classifier
* fix(anthropic): keep a backend's stream verdicts and join split SSE data lines before stamping
* fix(anthropic): map only the router's no-healthy-deployments refusal to unsupported
* fix(anthropic): answer unavailable for the turn on a transient caller denial and let the classifier deployment's timeout apply
* fix(anthropic): keep the user's whole opening message in the classifier transcript past its budget
* fix(anthropic): run the proxy's own access checks for the safeguards classifier call
The classifier and compaction sub-calls now pass through the same model access
checks as the parent request (key, team, team member, user, project, end user,
managed agent grants), with budgets left to the per-model budget check so
nothing is reserved. They also carry the parent's logging params and headers,
so a redaction header or per-request callback params apply to their own rows.
Only per-model RPM limits count against a sub-call now, since a key-wide or
team-wide RPM window is already spent by the parent request. The MCP
auto-execute loop classifies only its final response, a chat-bridge stream
without safeguards yields frames directly, and a classifier provider failure
logs one warning line instead of a traceback
* fix(anthropic): keep safeguards sub-calls off the parent's session routing and carry a body trace id
The classifier and compaction summary calls no longer get the parent's proxy_server_request, so a Claude Code session bound to a router no longer pulls them off their configured model. Redaction still reads the headers carried in metadata.
Their access checks now use the parent's resolved litellm_trace_id when the parent metadata has no trace_id, so a team that requires a trace id accepts a sub-call whose parent sent it in the body.
* fix(anthropic): keep the disable-callbacks header on safeguards sub-calls
* fix(proxy): charge per-model budgets from litellm_metadata when metadata holds only routing keys
* test(integration): add safeguard_results cells for the bridges, native routes, caller checks, and classifier failures
* fix(proxy): check the caller's budgets on the classifier call and keep failed access reads retryable
