코스를 그릴 때 찍는 마커 개수를 계정 단위 재화로 관리한다. 마커를 찍을 때마다 서버를 호출하지 않고 로컬에서 실시간으로 잔량을 표시/차감하다가, 코스 저장 시점에 실제 사용한 마커 수만큼 서버에 소비 요청을 보낸다. 잔량이 0인데 지도를 탭하면 팝업으로 광고 시청을 유도하고, 리워드 광고 시청 완료 시 서버에 지급 요청을 보내 잔량을 채운다. - data/domain/repository/DI: MarkerQuotaService·RemoteMarkerQuotaDataSource· MarkerQuotaRepository(Impl) 3계층, 기존 CourseRepository 패턴과 동일하게 구성 - RewardedAdManager: AdMob 리워드 광고 로드/노출을 감싸고, 시청 완료 시 rewardTransactionId(UUID)를 발급해 서버의 멱등성 처리에 사용 - DrawViewModel: markerQuotaBalance/consumeMarkerQuota/grantMarkerRewardFromAd 추가 - DrawActivity: 마커 잔량 칩 + 충전 버튼 UI, 마커 배치/해제 시 로컬 잔량 증감, 코스 저장 시 consumeMarkerQuota 호출 후 성공 시에만 업로드 진행, 잔량 소진 시 광고 유도 바텀시트 노출 AdMob App ID/광고 단위 ID는 Google 공식 테스트용 값으로 넣어둠 (local.properties: ADMOB_APP_ID, ADMOB_REWARDED_AD_UNIT_ID) — 실제 배포 전 본인 AdMob 계정의 값으로 교체 필요.

📝 WalkthroughWalkthroughAdds a marker quota system to the draw flow. The app retrieves, consumes, and refunds quota through new APIs. Users can earn five markers from rewarded ads. AdMob is configured and initialized at startup. ChangesMarker Quota Feature
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change adds client-side quota consumption and ad-based rewards, but the current implementation can permanently lose quota after failed saves, create duplicate courses from concurrent saves, and crash or enable invalid course saves when no quota remains. These issues should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

consumeMarkerQuota and uploadCourse calls so quota is not permanently consumed
before the course upload succeeds. Prefer a server-side reservation or atomic
save-and-consume operation; otherwise, add compensation to restore the reserved
quota on upload failure and ensure retries do not double-consume markers while
preserving loading-state handling.

1. markerQuotaBalance를 Int? = null로 바꿔, 서버 조회가 아직 안 끝난 상태와 실제 잔량 0을 구분. 조회 전에는 마커 배치를 막고 안내 토스트를 띄운다. 2. consumeMarkerQuota 성공 -> uploadCourse() 트리거를 액티비티 쪽 별도 LiveData 관찰로 나누지 않고, DrawViewModel.saveCourse() 하나의 코루틴 안에서 순차 체이닝하도록 변경. 기존 방식은 액티비티가 재생성되면 markerQuotaConsumeState의 sticky한 Success 값이 다시 흘러 uploadCourse()가 중복 호출될 수 있었다. 3. 업로드가 실패하면 이미 차감한 마커 재화를 grantMarkerReward API로 되돌려준다(광고 리워드 API의 멱등 처리를 재사용). 이전에는 업로드 실패 시 저장되지 않은 코스 때문에 마커만 잃는 문제가 있었다.

Prevent concurrent course saves.
saveCourse has no in-flight guard. DrawActivity keeps the draw action enabled while the loading bar is visible. A second save can start before the first upload finishes.
Each invocation consumes quota and uploads the same route. This can create duplicate courses and consume quota twice.
Add a ViewModel-owned save lock. Release it only after upload success or after the refund operation reaches a terminal state.
Also applies to: 117-139

Make quota refunds durable.
If the upload fails and the refund request also fails or the process ends, this code only logs the failure. The server quota remains consumed.
The generated rewardTransactionId is not persisted. A later retry cannot safely reuse the same idempotency key.
Store a pending refund with its transaction ID and retry it durably, or replace this compensation flow with a server-side atomic reservation or save operation.
