   - `CORE-001D1` is complete: portfolio/workspace persistence now uses an explicit unit-aware schema with strict validation and atomic saves.
-  - Remaining focus is `CORE-001D2` provider/cache normalization and `CORE-001D3` service entrypoint tightening.
+  - `CORE-001D2A` is complete: DataService quote/provider cache normalization is now a named boundary adapter with explicit symbol mismatch rejection and GLD quote-unit repair.

   - Pre-launch policy: unit-aware schema changes may be breaking until persistence is considered live; old flat payloads may fail loudly instead of being migrated.
   - See `docs/CORE-001D_BOUNDARY_CLEANUP_PLAN.md` for the current hotspot inventory and proposed sub-slices.

+summary: DataService quote payload normalization is now an explicit provider/cache boundary with tested repair and rejection rules.
+completed_notes:
+  - Added a named quote normalization adapter in `app/services/data_service.py` for cache/provider payloads.
+  - GLD quotes repair missing or empty `quote_unit` metadata to preserve CORE-002 behavior.
+  - Explicit symbol mismatches are now rejected instead of being silently rewritten.
+  - Mismatched cached quotes are discarded and refreshed from the provider path.
+  - Added focused boundary tests in `tests/test_data_service_normalization.py`.
+  - Validated with focused pytest coverage and `make build` on `main`.
