Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟠 High · up to This PR adds browser push subscription management and asynchronous Kafka delivery, but the current head can allow cross-member subscription deletion, lose or strand notifications, resend deliveries beyond their retry limit, and accept unsafe delivery targets; CI token permissions also remain overly broad. These concrete authorization, notification-correctness, and security risks make the PR not merge-ready until addressed. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

- Around line 73-92: Update PushSubscribe validation and
NotificationConverter.toPushSubscription to validate endpoint as an HTTPS URI
and verify that p256dh and auth are valid Base64URL values with the required Web
Push key lengths before persistence. Map any validation failure to the
documented NOTIFICATION_400_6 response instead of accepting or storing the
subscription.
In
`@src/main/java/com/whereyouad/WhereYouAd/domains/notification/domain/service/push/BrowserPushDataAccess.java`:
- Around line 114-146: Update recordResults to batch-load deliveries with
findAllById using the grouped delivery IDs, then map them by ID for result
processing instead of calling findById per group. Collect distinct non-null
expired subscription IDs while processing results and remove them with
subscriptionRepository.deleteAllByIdInBatch after processing, preserving the
existing success/failure updates and deletion warning behavior as appropriate.
In

- Around line 31-43: Update PushRetryScheduler.retryFailed so the Redis lock
remains valid for the entire retry lookup and Kafka publication, using an
ownership token and renewing the lease before LOCK_TTL_SECONDS expires, or
atomically claiming deliveries before loading retry targets. Also bound the
number of retry targets returned by findRetryTargets to prevent unbounded
batches, while preserving the existing duplicate-execution prevention.
In
`@src/main/java/com/whereyouad/WhereYouAd/domains/notification/persistence/entity/PushSubscription.java`:
- Around line 13-16: Update PushSubscription.java lines 13-16 to enforce
uniqueness on the membership_id and endpoint pair. In
PushSubscriptionService.java lines 44-52, update only the current member’s
matching endpoint without deleting or transferring another member’s
subscription. In lines 56-59, constrain unsubscribe by both endpoint and
membership_id.
In
`@src/main/java/com/whereyouad/WhereYouAd/domains/notification/presentation/docs/NotificationControllerDocs.java`:
- Around line 188-195: Update the unsubscribePush API documentation to include a
400 response describing validation failure for invalid subscription data,
specifically when PushUnsubscribe.endpoint is empty, while preserving the
existing 200 and 404 responses.
In
`@src/main/java/com/whereyouad/WhereYouAd/domains/notification/presentation/NotificationController.java`:
- Around line 174-181: Update unsubscribePush and the underlying unsubscribe
deletion flow to scope deletion by both request.endpoint() and the authenticated
user’s OrgMember identifier, rather than endpoint alone. Preserve idempotent
success when no matching subscription exists, and update the relevant
service/repository symbols accordingly.
In
`@src/main/java/com/whereyouad/WhereYouAd/infrastructure/client/kafka/KafkaPushNotificationEventProducer.java`:
- Around line 19-30: Update the push notification flow around
persistPushNotification and KafkaPushNotificationEventProducer.produce so Kafka
publication failures become recoverable: preferably persist the database record
and outbox event in one transaction and have a relay publish it; otherwise
persist FAILED on send failure and ensure PushRetryScheduler retries that state.
In
`@src/main/java/com/whereyouad/WhereYouAd/infrastructure/client/kafka/NotificationConsumer.java`:
- Around line 25-30: Update NotificationAlertEvent and the Kafka consumer flow
to include a producer-generated unique event ID, enforce uniqueness for that ID
in the inbox or notification persistence layer, and check it before invoking
sendBrowserPushToOrg. For already-recorded IDs, skip both persistence and push
dispatch while preserving normal processing for new events.
In
`@src/main/java/com/whereyouad/WhereYouAd/infrastructure/client/kafka/PushNotificationConsumer.java`:

recordResults are rethrown after logging, allowing the Kafka listener error
handler to apply its retry/backoff or DLT policy instead of acknowledging the
record. Configure the relevant DefaultErrorHandler accordingly, and add delivery
claiming or idempotent result handling to prevent duplicate pushes when
recordResults fails and the message is redelivered.

구독 해제를 요청 멤버의 구독으로 제한하세요.
Line 181의 서비스 호출은 현재 요청자의 조직 멤버십만 확인한 뒤 deleteByEndpoint(endpoint)를 실행합니다. endpoint를 아는 다른 조직 멤버도 해당 구독을 삭제할 수 있습니다.
삭제 쿼리를 endpoint와 요청자의 OrgMember 식별자로 제한하세요. 대상이 없어도 성공 처리하면 구독 해제의 멱등성은 유지할 수 있습니다.

실제 구독이 있는 멤버만 브라우저 푸시 대상으로 판정하십시오.
findPushEnabledForOrg는 알림 설정만 확인합니다. PushSubscription이 없는 멤버도 hasPushTargets에서 대상이라고 판정됩니다.
이 경우 클릭 급증 흐름은 쿨다운을 획득하고 알림을 생성합니다. 이후 loadTargets는 구독이 없으므로 실패 대상을 만듭니다. 외부 채널도 없으면 실제 수신자가 없는 조직이 알림 처리 완료 상태가 됩니다.
구독 존재 조건을 포함한 조회를 추가하십시오. hasPushTargets와 persistPushNotification이 같은 실제 수신자 조건을 사용하도록 수정하십시오.

@kingmingyu, 네. 6e1474a만으로는 이 리뷰 코멘트를 해결하지 못합니다.
이 커밋은 PushSubscription을 membershipId + endpoint 범위로 조회·삭제하게 변경했습니다. 이 변경은 좋습니다. 같은 브라우저 endpoint를 다른 멤버십이 공유할 수 있는 경우의 격리를 보장합니다.
하지만 BrowserPushDataAccess.hasPushTargets와 persistPushNotification은 아직 memberSettingRepository.findPushEnabledForOrg(...)만 사용합니다. 이 쿼리는 알림 설정과 활성 사용자만 확인합니다. PushSubscription 존재 여부는 확인하지 않습니다.
따라서 구독이 없는 멤버도 대상에 포함됩니다.
hasPushTargets()가true를 반환합니다.persistPushNotification()이NotificationDelivery를 생성합니다.loadTargets()에서 구독이 없음을 발견합니다.- 빈 대상을 만들고 실패 배송으로 처리합니다.
PushSubscription이 존재하는 멤버만 조회하는 공통 repository 쿼리를 추가하고, 두 메서드가 그 쿼리를 사용하면 이 코멘트가 해결됩니다.

P3 : 여기 Kafka Consumer 에서는 topics 에 web-push.topic:notification-push-events 로 되어서 application.yml 에 web-push.topics 값을 가져다 쓰되 없으면 기본값 notification-push-events 로 설정되도록 되어있는데, application.yml 에는 해당 값이 없는 것 같은데 의도하신 걸까요...?
대응되는 Producer 인 KafkaPushNotificationEventProducer 에는 private static final String TOPIC = "notification-push-events" 으로 final 필드 정의로 해놓은거 같아서 두 값을 통일하면 어떨까 해서 물어봅니다! Producer 쪽에서 final 필드를 public 으로 열어서 Consumer 에서도 사용하거나, application.yml 에 필드를 정의해서 Producer 에서 yml 값을 가져다 쓰도록 하는 둘 중 하나로 통일하면 좋을 거 같아요..!!

🌐 Web query:
W3C Push API PushSubscription unsubscribe user agent must not deliver push messages after unsubscribe endpoint semantics
💡 Result:
According to the W3C Push API specification, when the unsubscribe method is invoked on a PushSubscription object, the user agent is required to deactivate the push subscription [1][2][3]. As part of this deactivation process, the user agent MUST NOT deliver any further push messages for that specific subscription [1][2][4]. Furthermore, the specification mandates that both the user agent and the push service must delete any stored copies of the subscription's details [2][4]. If the user agent is unable to successfully notify the push service of the deactivation—for instance, due to network issues—it is instructed to retry the request to the push service for a reasonable duration [1][3]. The unsubscribe method returns a Promise that resolves to a boolean value indicating the outcome of the operation [5][2].

조직별 구독 해제와 브라우저 구독 해제를 분리하세요.
PushSubscription의 UNIQUE 제약은 membership_id와 endpoint의 조합에만 적용됩니다. 따라서 하나의 브라우저 PushSubscription이 여러 멤버십에 등록될 수 있습니다. 반면 unsubscribe는 현재 멤버십의 레코드만 삭제합니다.
클라이언트가 조직별 해제 전에 pushManager.unsubscribe()를 호출하면 다른 멤버십의 레코드가 비활성화된 구독을 참조합니다. 발송은 실패하고 FAILED 상태 및 재시도 대상으로 처리됩니다.
조직별 알림 해제에서는 서버 레코드만 삭제하도록 NotificationControllerDocs.java의 설명과 프런트엔드 호출을 수정하세요. 브라우저 구독 자체를 해제해야 하면 동일 endpoint의 모든 관련 레코드를 정리하는 별도 흐름을 정의하세요.

PushSubscriptionService.unsubscribe and its NotificationControllerDocs
documentation and frontend invocation so it deletes only the current
membership’s server-side subscription record without calling browser
pushManager.unsubscribe(). Define a separate flow for browser-level removal that
deletes all PushSubscription records sharing the same endpoint when that
behavior is explicitly required.
