+# HANDOFF — ECR-011 Engineer → Reviewer（re-submit）
+
+**From:** Engineer  
+**To:** Reviewer  
+**Date:** 2026-08-12  
+**ECR:** ECR-011  
+
+## Fixed
+
+- P1：`ecr011_test.go` 断言改为 `clothing` · `clothing_index` · `palette` · `wellness` · `source`  
+- TEST_REPORT 已更新  
+
+## Still SKIP locally
+
+Docker daemon 不可用 → integration 仍 SKIP。请 Reviewer 在有 Postgres 环境跑：
+
+```bash
+npm run deps:up
+cd apps/api && go test ./internal/integration/ -run TestECR011 -count=1 -v
+```
+
+## Owner next
+
+`STATE.owner = reviewer`
