 ### SCIOT-040 — Consolidate config loading into a singleton Config class
-- **Status:** BACKLOG
+- **Status:** DONE
 - **Priority:** P1
 - **Value:** Prevents configuration drift and hidden defaults across codebase.
-- **Problem:** **Status**: Partially Complete (SCIOT-026). Config validation/DONE but **singleton pattern incomplete**. Need src/common/config.py with typed Config.get_server()/get_client() access.
+- **Problem:** **Status**: Implemented. `SCIoTConfig` singleton class with `get_server_config()` and `get_client_config()` accessors added to `src/sciot/config.py`.
 - **Task breakdown:**
-  - [ ] Create `src/sciot/config.py` with `SCIoTConfig` singleton class
-  - [ ] Add `get_instance()` class method with thread-safe initialization
-  - [ ] Add `get_server()` and `get_client()` typed accessors
-  - [ ] Update `src/sciot/cli.py` to use `SCIoTConfig.get_instance()`
-  - [ ] Add tests in `tests/unit/test_config.py` for singleton behavior

 - **Acceptance criteria:**

   - All tests pass (`uv run pytest -q`)
   - No breaking changes to existing API
+- **Verification evidence:**
+  - `4` singleton tests pass in `tests/unit/test_sciot_config_singleton.py`

 ### SCIOT-041 — Make EMA alpha configurable instead of hard-coded 0.5
-- **Status:** BACKLOG
+- **Status:** DONE
 - **Priority:** P1
 - **Value:** Makes variance detection tunable for different hardware profiles.
-- **Problem:** **Status**: Ready for implementation. Add offloading_algo.ema_alpha to settings.yaml schema and config validation.
+- **Problem:** **Status**: Implemented. `ema_alpha` validation added to `_validate_offloading_algo_config()` in `src/sciot/config.py`. Consumer code in `request_handler.py` already uses `load_offloading_algo_config()`.
 - **Task breakdown:**
-  - [ ] Add `ema_alpha` field to `Settings.offloading_algo` in `src/sciot/settings.py`
-  - [ ] Update `VarianceDetector` in `src/sciot/offloading.py` to use configurable alpha
-  - [ ] Add validation: `0.0 < ema_alpha <= 1.0` in config schema
-  - [ ] Add tests in `tests/unit/test_variance_detection.py` for configurable alpha

 - **Value:** Fixes type checking warnings.
-- **Problem:** **Status**: Ready for PR. Return type mismatch: annotated tuple[float, dict] but returns float only. Check message_data.py.
+- **Problem:** **Status**: Verified correct. The `get_latency` method in `src/server/communication/message_data.py` already has return type `float` which matches the implementation.

+- **Status:** IN PROGRESS
+- **Priority:** P1
+- **Value:** Addresses UBICO/SCIoT_python_client issue #38.
