📝 WalkthroughWalkthroughLegacy ChangesOpenAI API 호환성
Estimated code review effort: 4 (Complex) | ~60 minutes Mergeability Score: 🟠 High · up to Although this PR tightens request validation, concurrent requests can still receive each other’s sampling or penalty settings, while passthrough requests can bypass validation and receive 200 responses for unsupported options. These are concrete correctness and API-contract risks, so the PR is not merge-ready until the affected paths are fixed; usage attribution and lint follow-up also remain.

PASSTHROUGH_TRIGGER_KEYS(response_format,tools,tool_choice,functions,function_call)가 있으면 이 블록이 즉시 반환합니다. 그래서 Line 2017-2134의 검증은 실행되지 않습니다. 누락되는 항목은 다음과 같습니다.
stream,stream_optionsuser,metadata,service_tierseed,stop,n,logprobs,top_logprobsstore,prediction,reasoning_effort예:
{"tools": [...], "seed": 7, "store": true, "stream": true}는 검증 없이 provider로 전달되고 200을 받습니다. 같은 요청에서tools만 제거하면 400을 받습니다. 결과적으로 동일 옵션이 경로에 따라 다르게 처리됩니다. 이는 PR이/v1/responses에서 적용한 "passthrough 전에 검증" 원칙과도 어긋납니다.미지원 옵션 검증을 passthrough 분기보다 앞으로 이동하세요.

Inline comments:
In `@contextual_orchestrator/cost_ledger.py`:
- Around line 593-600: Update the raw SQL cur.execute calls in cost_ledger.py to
suppress Ruff S608 using inline Ruff-compatible noqa annotations on all four
reported statements, while preserving the existing parameter binding and nosec
annotations.
- Around line 225-239: Update UsageRecord.as_dict() to preserve the served model
identifier in a separate served_model_name field while retaining
attribution.model_name as model_name when explicitly provided. Add the field to
the SQL schema migration and _USAGE_COLUMNS, and update related persistence/API
tests to verify both values.
In `@contextual_orchestrator/orchestrator.py`:
- Around line 253-275: Update the chat method to accept request-scoped
presence_penalty and frequency_penalty arguments, compute their effective values
using the corresponding defaults when omitted, and pass those values through the
ModelClient.chat request path. Record the effective penalties alongside the
existing temperature and top_p diagnostics, without relying on mutating shared
defaults.
In `@contextual_orchestrator/server.py`:
- Around line 541-569: Replace the ambiguous en dash characters in the docstring
of _validate_completions_logprobs with standard hyphen-minus characters,
preserving the surrounding wording and behavior.
- Around line 1879-1910: Remove request-specific sampling assignments and
restoration from the /v1/completions flow around coordinator.complete, passing
the values as call arguments instead. Apply the same change in
contextual_orchestrator/server.py lines 2136-2180 for /v1/chat/completions,
including forwarding them to _stream_route_completion; do not modify shared
orchestrator.client state.
In `@tests/test_responses_input_metadata_fail_closed.py`:
- Around line 122-130: Add a test alongside
test_http_responses_stream_true_fail_closed that submits non-boolean stream
values such as "true" and 1, and assert each response returns HTTP 400 with an
invalid_stream error. Keep the existing true-value rejection test unchanged.

요청별 penalty 값을 chat 호출 경로에 전달하십시오.
ThreadingHTTPServer는 여러 요청을 동시에 처리합니다. 현재 ModelClient.chat는 공유된 default_presence_penalty와 default_frequency_penalty를 읽습니다. 따라서 요청 처리 중 기본값을 변경하면 동시 요청이 서로의 penalty 값을 사용하거나 잘못 복원할 수 있습니다.
두 penalty를 요청 범위의 인자로 전달하고, 다른 sampling 값과 함께 유효 값을 계산하십시오.

🩺 Stability & Availability | 🔴 Critical | 🏗️ Heavy lift
두 엔드포인트가 공유 orchestrator.client에 요청별 sampling 값을 대입합니다. build_server는 ThreadingHTTPServer를 반환하므로 요청은 병렬로 실행됩니다. 단일 공유 client 속성을 대입하고 finally에서 복원하는 방식은 값 교차 적용과 기본값 영구 오염을 만듭니다. 근본 원인은 요청 범위 상태를 전역 객체에 저장하는 설계입니다.
contextual_orchestrator/server.py#L1879-L1910:/v1/completions에서 속성 대입을 제거하고 sampling 값을coordinator.complete호출 인자로 전달하세요.contextual_orchestrator/server.py#L2136-L2180:/v1/chat/completions에서도 동일하게 호출 인자 방식으로 변경하세요. 스트리밍 경로(_stream_route_completion)에도 같은 값을 전달해야 합니다.

stream 타입 검증을 테스트로 고정하세요.
현재 테스트는 stream=True만 거부하는지 확인합니다. stream="true" 또는 stream=1을 허용하는 회귀는 이 테스트 집합을 통과합니다. invalid_stream과 HTTP 400을 검증하는 비-boolean stream 테스트를 추가하세요.
