 Notes:
 
-- This slice follows the external operation consumer cleanup and keeps the old
-  aggregate facade, DTO/helper, response, and operation contract guards active.
-- External DTO consumers now name ECStore-owned object DTOs through local
-  semantic aliases in their owning crates or RustFS storage boundary module.
-- The slice does not alter object metadata shape, options defaults,
-  reader/writer behavior, delete replication DTO handling, scanner cache
-  semantics, heal storage metadata semantics, Swift/S3 Select object reads,
-  notification event payloads, S3 response DTO mapping, or runtime storage
-  behavior.
-- The CI follow-up preserves empty-object erasure reconstruction by filling
-  missing zero-length shards before calling encoders that reject zero-byte SIMD
-  shard sizes.
+- This slice is stacked on API-026 while `rustfs/rustfs#3566` is pending.
+- Direct ECStore `store_api` references outside ECStore now remain only at
+  explicit alias boundary points.
+- The slice does not alter table catalog storage behavior, IAM config storage,
+  admin zip download object reads, capacity dirty-disk behavior, heal
+  integration semantics, scanner cache I/O, Swift/S3 Select object reads,
+  notification event payloads, or ECStore DTO definitions.
 
 ## Handoff Notes
 
-- External DTO consumer cleanup is based on `main` after
-  `rustfs/rustfs#3565` merged and carries the empty-object erasure recovery
-  CI follow-up because the merged PR did not include that post-merge fix.
 - Continue with larger consumer-migration batches; keep ECStore-owned
   DTOs/readers/walk filters in ECStore until their concrete behavior is isolated
   enough for a pure-move slice.
