📝 WalkthroughWalkthroughPeople API에 저카디널리티 HTTP 텔레메트리 미들웨어를 추가했다. 메서드와 라우트를 제한하고, 요청 처리 시간·상태·오류 유형을 기록한다. 예외와 내보내기 실패를 요청 처리와 분리한다. 관련 요구사항과 회귀 테스트를 추가했다. ChangesPeople API 운영 텔레메트리
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The new telemetry boundary can currently reject a People request if its injected clock fails, despite telemetry being intended as best effort. This is a bounded availability risk requiring owner awareness or a small follow-up; the reported checks otherwise pass. Sequence Diagram(s)sequenceDiagram

🔍 Telemetry middleware defined but never wired in
PeopleHttpTelemetryMiddleware is not instantiated or registered anywhere in the People API app, so no live traffic is measured yet. This matches the stated slice scope, but a follow-up must wire it in for the telemetry to have effect.

🔍 Record-instance paths are not classified
classify_people_http_route matches only the two-segment collection routes; an instance path like /v1/employment-records/{id} returns None and loses route attribution. Such URLs are produced in Location headers (mutation_http.py:614-637). Confirm the allow-list covers all deployed endpoints whose traffic should be measured.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
시작 시각 측정 실패가 요청을 중단시킵니다.
self.clock() 호출이 try 밖에 있습니다. 주입된 clock이 예외를 던지면 래핑된 앱이 실행되기 전에 예외가 호출자에게 전파됩니다. 이는 "텔레메트리 장애가 HR 요청을 거부할 수 없다"는 이 모듈의 계약(150-155행, 문서 18행)과 어긋납니다. _record_completion은 이미 방어되어 있으므로 시작 시각도 동일하게 방어하십시오. 시작 시각을 얻지 못하면 측정을 생략하고 요청은 그대로 진행하십시오.

Buyer-visible gap

develop@9e3e4847510e1e612b48474ba42b177b8ed824dfdefines candidate SLOs but has no executable People HTTP measurement boundary. Operators therefore cannot derive request-volume, latency, or server-error evidence from a deliberately low-cardinality, PII-safe contract before choosing an OpenTelemetry/export backend.This Orgmetra-only slice adds an adapter-neutral request-completion measurement boundary. It does not copy tenant/person/candidate IDs, raw URL paths, query strings, headers, bearer tokens, actor references, HR values, support references, backend exception messages, database details, or other uncontrolled request data into metric dimensions, and telemetry exporter failure cannot change the governed HR request result.

developcurrently exposes separate dependency-injected People ASGI adapters rather than one canonical production composition root, so this PR deliberately does not pretend to register itself in a deployment entrypoint that does not exist. Deployment composition must wrap the selected People ASGI app withPeopleHttpTelemetryMiddlewareand supply the metric sink; SDK/Collector/exporter configuration, current required/recommended resource/network attributes, deployment-specific known-method policy, histogram aggregation/temporality/retention and alert/SLO policy remain deployment-owned follow-up work.Fresh review also noted collection Location paths such as
/v1/employment-records/{id}. Those are not deployed People request endpoints on protecteddevelop: current mutations arePOST /v1/employment-records,/v1/position-records, and/v1/assignment-records, while the governed read endpoint is the tenant/person route. Unknown/non-endpoint paths intentionally emit no route label rather than copying a raw path into telemetry. Neither observation is treated as a defect or falsely resolved.Exact-current-head evidence
