서브테스트(duplicate token_ref, duplicate token_hash_sha256, empty principal_ref, non-hex hash, non-64-length hash)로 구성했고, "raw-looking token field 없음" 검증은 YAML 로드 케이스 대신 별도 리플렉션 테스트 `TestOpenAIPrincipalTokenConf_NoRawTokenField`로 분리했다(`OpenAIPrincipalTokenConf`의 YAML 태그 화이트리스트를 검사해 raw token 필드 재도입을 막는다). 계획의 정성적 요구(raw token 미저장 검증)는 그대로 충족한다. +- `TestRoutesDoNotUseMetadataUserForPrincipal`을 계획에 없던 별도 테스트로 추가했다: `metadata.user`가 신원 source로 쓰이지 않음을 spoofing 방지 테스트(`TestChatCompletionsAddsPrincipalMetadataFromBearerToken`)와 별도로, 미인증 open 엔드포인트 케이스에서도 확인한다. +- `TestChatCompletionsPrincipalMetadataEmptyWhenUnauthenticatedDirectCall`을 추가했다: 기존 테스트 다수가 `withAuth`를 거치지 않고 핸들러를 직접 호출하므로, principal 미해결 context에서도 `principalMetadata`가 nil을 반환해 기존 테스트 결과에 영향을 주지 않음을 확인한다(회귀 방지 목적, 계획에 명시되지 않았으나 범위 내). + +## 주요 설계 결정 + +- Auth 우선순위: `principal_tokens`가 설정되어 있으면 SHA-256 해시 매칭을 먼저 시도하고, 매칭 실패 시 legacy `bearer_token`으로 폴백한다(둘 다 설정 가능, 공존). 어느 쪽도 설정되지 않았으면 기존 동작과 동일하게 인증을 요구하지 않는다(open, `principalSourceUnknown`). +- Principal 신원은 `context.Context`를 통해 `withAuth` → handler로 전달한다(`principal.go`의 `withPrincipal`/`principalFromContext`). 별도 request-scoped 저장소나 헤더 재작성을 도입하지 않았다. +- Dispatch metadata(`iop_principal_ref`, `iop_principal_alias`, `iop_token_ref`, `iop_principal_source`)는 caller가 보낸 `metadata.*` 파싱 이후 마지막에 **덮어쓰기(overwrite)** 방식으로 주입한다. 이는 caller가 `metadata.iop_principal_ref` 같은 키로 신원을 스푸핑하는 것을 원천 차단하기 위함이다(단순 merge-if-absent가 아님). +- `chat_handler.go`에서 principal metadata를 `runMeta`에 한 번만 병합하면 normalized path(`chatRunMetadata`)와 provider tunnel path(`submitChatCompletionTunnel`)가 같은 `runMeta`를 소비하므로 별도 중복 주입 없이 두 경로 모두에 전파된다. +- 해시 비교는 후보별로 `crypto/subtle.ConstantTimeCompare`를 사용한다. `principal_tokens` 리스트 전체를 순회하는 시간 자체는 매칭 위치에 따라 달라질 수 있으나(짧은 운영 리스트 기준 실질적 위험 낮음), 각 후보 비교 자체는 타이밍 누출을 피한다. 계획의 "constant-time hash match" 요구를 이 수준으로 해석했다. +- Ollama API passthrough(`/api/*`)는 계획 범위에 principal metadata 전파 대상으로 명시되지 않아 손대지 않았다(체크리스트는 Chat Completions/Responses/provider tunnel만 명시). + +## 사용자 리뷰 요청 + +_기본값은 `없음`이다. 구현 중 새 결정이 필요해 보여도 직접 질문하거나 선택지를 제시하거나 `request_user_input`을 호출하지 않는다. 이 섹션은 선택된

"provider_reported vs unavailable" 판별은 wire presence가 아니라 관측값 `> 0` 휴리스틱으로 처리한다. token counter는 값이 0이면 series를 만들지 않으므로 reported-0과 unreported를 구분할 실익이 없고, reasoning-observed(S07) 케이스는 정확히 `reasoning_tokens==0 && reasoningChars>0`으로 잡힌다. +- **Prometheus 등록 방식**: `usage_metrics.go`에서 `promauto.NewCounterVec`로 default registry에 package-level counter를 등록한다. 기존 `packages/go/observability.ServeMetrics`의 `promhttp.Handler()`(default registry)로 `/metrics`에 그대로 노출된다. +- **reasoning token 미추정 보장**: `emitUsageMetrics`는 `obs.reasoningChars > 0 && obs.reasoningTokens == 0`일 때만 `iop_openai_reasoning_observed_total`/`iop_openai_reasoning_chars_total`을 올리고, token counter(`token_type="reasoning"`)에는 절대 char 기반 추정치를 넣지 않는다 (SDD S07). +- **passthrough body byte-identity**: pure passthrough 경로에서 provider usage는 body(JSON/SSE), USAGE frame에서 관측만 하고 응답 byte를 바꾸지 않는다. metric emit은 기존 `defer`에 `metricStatus` 추적을 더해 단일 지점으로 모았다. +- **edge_id 주입**: `Server.SetEdgeID`를 추가하고 `input.NewManager`에서 `cfg.Edge.ID`를 전달한다. label allowlist(`edge_id`, `principal_ref`, `principal_alias`, `token_ref`, `model_group`, `endpoint`, `response_mode`, `status`, `usage_source`, `token_type`)는 raw token/prompt/response/request_id/session_id를 배제한다 (SDD S08). +- **scope 제한**: metric emit은 `chat.completions`/`responses`

block에서 사용합니다. +3. **sidebandUsageObservation limitation**: `sidebandUsageObservation`은 input/output token만 지원하므로, reasoning/cached_input/chars는 sideband metric에 반영하지 않습니다. +4. **test helper
