Refresh handling moves to a separate API, so the aggregate flow no longer needs to detect expire CDC items and reroute them. Drops: - `isExpire` branching in `createTopkEvent` / `processTopk` / `aggregateTopk` - `isExpire` field on `EdgeAggregationEvent` and its properties-based `of` overload Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Follow-up on the terminology change from #400: the score row is still valid at the refresh timestamp, just due for a rebuild. Applied end-to- end so the aggregate flow and its persisted schema line up: - `AggregationConstants`: `TOPK_EXPIRE_TABLE` / `_PARTITIONS` and `expireSource` / `expireTarget` renamed - `AggregationService`: local `expiresAt` and property key `"expiresAt"` renamed - Refresh tracker table schema: column `expiresAt` → `refreshAt`, index `expires_at_asc` → `refresh_at_asc`, table comment updated Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Summary
Add an endpoint that runs a topk aggregation for a batch of edge events. For each event, the service queries the group's aggregation and writes the score row into the topk score table.
Changes
POST /graph/v3/aggregations— accepts anAggregationItemRequestand returns per-itemAggregationResult.AggregationService.aggregate(type, items)— fans items out to events, dispatches per aggregation type, resolves ranges ({source}/{target}/{_source}/{_target}/ user properties), writes score entries to the score table keyed by${entity}|${topkName}.EdgeAggregationEventdomain model for the item × group unit.How to Test
./gradlew :engine:test --tests "com.kakao.actionbase.engine.service.AggregationServiceSpec"./gradlew :server:test --tests "com.kakao.actionbase.server.api.graph.v3.metadata.MetadataAggControllerE2ETest"AI Assistance
