Code Review
This pull request introduces a robust user analytics system using an Adapter pattern to integrate GA4 and Amplitude, featuring an AnalyticsManager, dedicated providers, and custom hooks for tracking page views and user interactions. Feedback highlights a critical security risk concerning potentially malicious dependency versions. Other recommendations focus on improving maintainability by using defined constants for language fallbacks and correcting inconsistencies between the documentation, technical contracts, and the implementation.

패키지 버전이 의심스럽습니다. package.json과 package-lock.json에 명시된 @amplitude/analytics-browser의 버전 2.39.0과 axios의 버전 1.13.4는 공식 npm 레지스트리에 존재하지 않는 것으로 보입니다. 이는 오타일 수도 있지만, typosquatting을 통한 악성 패키지 설치의 위험이 있습니다.
보안을 위해 공식 레지스트리에서 각 패키지의 최신 안정 버전을 확인하고 수정해 주시기 바랍니다. 예를 들어, @amplitude/analytics-browser의 최신 버전은 2.9.0입니다.

문서에 기재된 trigger_context 값이 실제 구현과 다릅니다. 이로 인해 대시보드 사용자가 데이터를 해석할 때 혼란을 겪을 수 있습니다.
timer_save_prompt는 코드에서timer_modal로 사용되고 있습니다.share_prompt는 코드에서share_save로 정의되어 있습니다.
문서의 내용을 실제 구현과 일치시켜 주시기 바랍니다.

타입 정의가 구현과 일치하지 않습니다. table_id의 타입을 number | string으로 정의하셨지만, 실제 구현(src/util/analytics/types.ts)과 데이터 모델에서는 비회원 케이스를 위해 'guest'라는 특정 문자열만 사용하므로 number | 'guest'로 더 명확하게 정의하는 것이 좋습니다. 계약 파일의 타입을 더 구체적으로 수정하면 타입 안정성과 코드 명확성을 높일 수 있습니다.
이 변경은 TableSharedProperties, TimerStartedProperties, DebateCompletedProperties, DebateAbandonedProperties, TemplateUsedProperties 인터페이스에 모두 적용되어야 합니다.

구현 계획 문서의 내용이 실제 구현과 다릅니다. 체류 시간 측정 방식에 대해 'SDK 기본'을 사용한다고 기재되어 있지만, data-model.md와 실제 구현 코드(usePageTracking.ts)에서는 화면별 체류 시간 측정을 위해 duration_ms를 직접 계산하는 방식을 사용하고 있습니다. 문서의 일관성을 위해 이 부분을 실제 구현 내용에 맞게 수정해 주세요.

하드코딩된 폴백(fallback) 언어 사용은 유지보수성을 저해할 수 있습니다. 'ko' 대신 src/util/languageRouting.ts에 정의된 DEFAULT_LANG 상수를 사용하면, 향후 기본 언어 변경 시 한 곳만 수정하면 되므로 코드의 일관성과 유지보수성이 향상됩니다. 이 패턴이 프로젝트의 다른 파일에서도 반복되고 있으니 함께 수정하는 것을 권장합니다.

Inline comments:
In `@docs/analytics-dashboard.md`:
- Around line 295-299: Update the docs' trigger_context examples to match the
code by replacing `timer_save_prompt` with `timer_modal` and `share_prompt` with
`share_save`, ensure existing `landing_header` remains, and add the missing
code-defined triggers `landing_table_section` and `protected_route` so the
example list matches the constants defined in
src/util/analytics/loginTrigger.ts.
In `@specs/feat/443-user-analytics/plan.md`:
- Around line 156-160: The fenced code blocks in
specs/feat/443-user-analytics/plan.md are missing language tags and trigger
markdownlint MD040; update each triple-backtick block (including the ones around
the snippets at the shown ranges and the additional ranges 164-169, 173-176,
182-185, 192-195, 214-217) to include a language tag such as text (e.g., replace
``` with ```text) so markdownlint passes; search for all occurrences of ``` in
plan.md and add the tag consistently.
In `@specs/feat/443-user-analytics/research.md`:
- Around line 8-19: The Amplitude plan limits are incorrect: replace every
instance that states "Starter 플랜: 50,000 MTU" (and related mentions in the same
sections at lines noted in the review) with the correct "Starter 플랜: 10K MTU",
update any consequential statements (e.g., the assessment that 50K MTU is
sufficient) to reflect the 10K limit, and correct any references to free vs.
Starter plan capabilities accordingly; also add a verification date and cite the
official Amplitude pricing page as the source for these changes so future
readers can verify the claim.
In `@src/hooks/usePageTracking.ts`:
- Around line 53-72: Multiple handlers (window 'pagehide' and 'beforeunload'
plus the SPA cleanup) can cause duplicate page_leave events; add a guard/ref
(e.g., hasTrackedPageLeaveRef or isPageLeaveTracked) checked and set inside
handlePageHide and in the SPA cleanup code path so trackEvent('page_leave', ...)
and analyticsManager.flush() only run once per page leave, and reset that flag
when a new page is entered (where entryTimeRef is updated or in the page_view
tracking logic) so future navigations can fire again; update references to
handlePageHide, the useEffect that registers pagehide/beforeunload, and the
existing cleanup routine to use this guard.
In `@src/page/DebateEndPage/DebateEndPage.tsx`:
- Around line 20-24: The hook useGetDebateTableData is being called with tableId
before URL validation, causing requests with NaN; fix by deriving a validated id
(e.g., parse id from useParams into parsedId and ensure
Number.isFinite(parsedId) or !Number.isNaN(parsedId)) and only invoke the query
(or pass enabled: Boolean(validatedId)) when the id is valid — update the call
to useGetDebateTableData to be conditional or use its enabled option so getTable
is never called with NaN.
In `@src/page/DebateVoteResultPage/DebateVoteResultPage.tsx`:
- Around line 65-70: The event is fired too early; move the
trackEvent('poll_result_viewed', { poll_id: pollId }) call out of the current
useEffect that only checks isPollIdValid and instead fire it only after the poll
data successfully loads (e.g., in the API success handler or a useEffect that
watches the poll data/loading state). Specifically, remove the trackEvent from
the useEffect that references isPollIdValid and pollId, and invoke trackEvent in
the code path that confirms successful data load (for example when pollData !==
null or isLoaded === true) so it only executes once per successful render; keep
references to trackEvent and pollId unchanged.
In `@src/page/LandingPage/hooks/useLandingPageHandlers.ts`:
- Line 41: The hook is building a language-aware homePath via
buildLangPath('/home', lang) (homePath) but several analytics payloads still
hardcode trigger_page: '/home'; update all occurrences of trigger_page in
useLandingPageHandlers (the four places currently using '/home') to use the
homePath variable instead so analytics record the language-prefixed path
consistently (e.g., replace trigger_page: '/home' with trigger_page: homePath).
In `@src/page/TableSharingPage/TableSharingPage.tsx`:
- Around line 71-87: The code currently saves template origin as soon as
isTemplateEntry is true, which can persist for invalid decodedData and
misattribute later template_used events; update the effect so that template
origin is only set when decodedData is successfully validated (i.e., after
decodedData exists/passes the same checks you use elsewhere) or, alternatively,
ensure you clear the stored origin when decodedData validation fails; target the
same logic around encodedData/isTemplateEntry and the setTemplateOrigin call in
TableSharingPage (and any sessionStorage usage) so the origin is only persisted
on a successful decode and removed on decode failure.
In `@src/page/TimerPage/hooks/useDebateTracking.ts`:
- Around line 82-86: The current handleVisibilityChange fires
sendAbandonEvent('visibility') immediately on document.visibilityState ===
'hidden', which falsely marks brief tab switches as abandon; modify
handleVisibilityChange to start a timeout (e.g., 10s) when visibility becomes
'hidden' and only call sendAbandonEvent('visibility') and set
isDebateActiveRef.current = false when that timeout elapses, and cancel/clear
that timeout if visibility returns to 'visible' before the delay so the debate
remains active; reference handleVisibilityChange, sendAbandonEvent, and
isDebateActiveRef to implement the delayed-abandon logic and ensure the timer is
cleared on unmount.
In `@src/util/analytics/providers/ga4Provider.ts`:
- Around line 73-75: In the reset() method of ga4Provider (the function named
reset), replace the incorrect call ReactGA.set({ userId: undefined }) with
ReactGA.set({ user_id: null }) so the GA4 user ID key and value are correctly
reset (use the snake_case key "user_id" and null as the value).

origin.template_label exists and use it, falling back to
`${origin.organization_name} - ${origin.template_name}` only if absent. Update
the trackEvent payload construction (where table_id and other fields are set) to
reference origin.template_label when present to keep consistency with
setTemplateOrigin and stored state.
In `@src/routes/ProtectedRoute.tsx`:
- Around line 22-27: The render currently calls setLoginTrigger inside the
ProtectedRoute render when !isAuthenticated; move that side-effect into a
useEffect to preserve render purity. Inside the ProtectedRoute component add a
useEffect that watches [isAuthenticated, location.pathname] (or just
[isAuthenticated, location.pathname]) and when !isAuthenticated calls
setLoginTrigger({ trigger_page: location.pathname, trigger_context:
'protected_route' }); then remove the setLoginTrigger call from the JSX branch
and still return <Navigate to={homePath} state={{ from: location }} replace />
when not authenticated. Ensure the effect guards against running when
isAuthenticated is true so the trigger is only set during unauthenticated
transitions.
In `@src/util/analytics/providers/amplitudeProvider.test.ts`:
- Around line 52-55: Update the test for setUserProperties to not only assert
amplitude.identify was called but also verify the Identify object passed
contains the expected user properties; when calling provider.setUserProperties({
user_type: 'member', language: 'ko' }) assert that amplitude.identify was
invoked with an Identify-like argument that includes those keys/values (e.g.,
check for an object containing the user properties or the Identify's
set/operations that hold user_type and language) so the test validates the
actual payload as well as the call.

Amplitude 요금제 정보가 정확하지 않습니다 - 즉시 수정이 필요합니다.
문서의 "Starter 플랜: 50,000 MTU"는 틀렸습니다. 현재 Amplitude Starter 플랜의 실제 한도는 10K MTU입니다. 이는 의사결정(예: "토론 타이머 서비스의 예상 사용자 규모는 50K MTU 이하로 충분")에 직접 영향을 미칩니다. Plus 플랜 가격($49/월)은 정확하지만, 무료 플랜 개념과 Starter 플랜의 실제 제한 사항을 다시 확인하고 수정하세요. 향후 업데이트 시에는 정보 검증 날짜와 공식 출처를 함께 기재하십시오.

📝 작업 내용
개요
회원/비회원 플로우별 유저 유입 및 전환 흐름을 분석하기 위한 이벤트 트래킹 시스템을 구축했습니다.
기존의 GA4 단독 방식에서 벗어나, Amplitude + GA4 듀얼 프로바이더 구조로 전환했습니다.
전체 구조 한눈에 보기
이 구조 덕분에 어떤 분석 도구를 추가하거나 교체해도 각 페이지 코드는 전혀 바꿀 필요가 없습니다.
핵심 구현:
src/util/analytics/analytics의 핵심 로직이 모두 여기에 있습니다.
analyticsManager.ts— 중앙 허브모든 이벤트에는 공통 속성이 자동으로 붙습니다:
user_type:member(로그인) /guest(비로그인)language: 현재 서비스 언어 (ko,en등)page_path: 이벤트 발생 시점의 URL 경로providers/— 실제 전송 담당amplitudeProvider.tsga4Provider.tsgtag)로 이벤트 전송noopProvider.tsloginTrigger.ts— 로그인 유발 맥락 추적로그인 버튼은 여러 곳에 있습니다 (헤더, 타이머 모달, 공유 저장 등).
