* feat(guardrails): add headroom guardrail for message compression Adds a headroom guardrail that compresses request messages via POST /v1/compress before they reach the LLM. The guardrail implements apply_guardrail so it runs on the unified guardrail path; it receives pre-built structured_messages (OpenAI format) from the translation layer, calls the headroom compression service, and returns the compressed messages as structured_messages. Set x-headroom-bypass: true on the request to skip compression. Also adds structured_messages write-back support to the OpenAI and Anthropic translation handlers: when apply_guardrail returns structured_messages, those are written to data["messages"] directly (OpenAI) or reverse-translated via anthropic_messages_pt (Anthropic) instead of falling through to the existing text-patch path. This is a prerequisite for any guardrail that needs to replace the full message list rather than patch individual text spans. * fix(guardrails/headroom): add @log_guardrail_information to populate guardrail_information in spend logs * style: fix ruff format violations * fix(lint): replace deprecated typing aliases with builtin generics (UP006/UP037) * fix(guardrails): only write back structured_messages when guardrail actually changed them * fix(guardrails/headroom): raise 502 when compression returns empty message list * fix(guardrails/headroom): catch transport errors and fix stale debug log * fix(guardrails/anthropic): strip system messages before anthropic_messages_pt reverse-translation * fix(guardrails/anthropic): strip cache_control from thinking blocks after write-back * debug(headroom): add INFO logging to trace guardrail execution * debug(headroom): use print() for immediate visibility * debug(headroom): print request_data keys to diagnose metadata dict mismatch * fix(guardrails/anthropic): propagate guardrail info to logging_obj.metadata for spend log * fix: use model_call_details litellm_params metadata on Logging object * fix(guardrails/anthropic): write guardrail info to litellm_params attr not model_call_details copy * fix: read slg_info from litellm_metadata when metadata key absent * fix: write slg_info to both litellm_params attr and model_call_details copy * chore: remove debug prints; fix now verified end-to-end * refactor(guardrails): move spend-log sync to shared helper in custom_guardrail.py - Add _sync_guardrail_info_to_logging_obj in custom_guardrail.py; call it from both async and sync wrappers in @log_guardrail_information, fixing guardrail_information=null in spend logs for all passthrough routes (/v1/messages, /v1/responses, etc.) in one place - Remove the 35-line inline sync block from the anthropic translation handler - Wrap response.json() in try/except in headroom.py to 502 on HTML/truncated responses - Drop redundant headers.get(BYPASS_HEADER.lower()) — header key already lowercase - Add regression tests for _sync_guardrail_info_to_logging_obj * fix(lint): reduce _sync_guardrail_info_to_logging_obj complexity below C901 threshold * fix(lint): simplify _sync_guardrail_info_to_logging_obj to reduce McCabe complexity * fix(lint): extract _append_slg_to_litellm_params to reduce McCabe complexity * fix(lint): extract _write_back_structured_messages to reduce process_input_messages complexity |
