Rename PredictionMetadata (prediction_metadata.py) to MongoActivities (mongo.py) and move update_simple_metrics_adaptive_state there from ModelMetrics, so both Mongo-backed activities share one class and repository (PR #59 review, agreed with the class author). write_prediction_metadata is unchanged; the pure hysteresis helpers stay in model_metrics.py. References in activities.py, docstrings and tests updated.
Drop the try/except around update_simple_metrics_adaptive_state in the workflow and the broad except in the activity, so Mongo failures fail the run and show up in the Temporal metrics (PR #59 review). Invalid frequency_alert stays a warning + skip (the orchestrator ignores it too) and a malformed adaptive_state is read as not escalated.
Requirements follow the release; only sientia_model>=0.12.0 (RegressionMetrics),
model-library@0.13.1 and scikit-learn==1.8.0 (local) are kept from this branch.
Simplify merge in retrain: expose timestamp explicitly for join
Refactor evaluation_data merge to reset both frames' index into a
"timestamp" column before joining, instead of merging on index then
copying it out afterward. Same validate='one_to_one' safety check,
fewer intermediate steps.
Harden retrain merge and OPC write against silent failures
- pandas merge now uses validate='one_to_one' so duplicated timestamps
from wrapper.retrain fail loudly instead of silently multiplying rows
- OPC write_data raises OpcClientNotInitializedError instead of a bare
assert when client is torn down between validation and write, so
callers get a reported error instead of an AssertionError
- add regression test covering the torn-down client path

SIENTIAPDE-1646 Merge origin/main into release/SIENTIAPDE-1646
Bring main up to date while keeping this branch's sync execution, PluginStore
runtime and sientia_model (SientiaMLflowRepository/SientiaModel) structure.
Resolution decisions:
- OPC: keep the sync asyncua.sync implementation; port main's server_uri
validation, e2e race fix (lock held until released) and the new unit tests
converted to sync.
- Model import workflow (.sientia bundles), joblib/transform flavors and the
local MLFlowRepository (model_repository.py) are dropped, with their tests,
docs, metrics, env vars and connectors config.
- Worker: drift/simple_metrics stay pinned to the 'core' runtime; port main's
HOSTNAME pod id, logger-based prometheus startup and sys.exit after finally.
- values.yaml removed, following main (SIENTIAPDE-1945).
- Deps: keep sientia_model; take main's fsspec/s3fs/botocore/boto3 pins and
sientia_do>=1.12.2; drop import-only deps (pynacl, cryptography, pymongo,
python-dotenv, pycaret, joblib, gcsfs).
- e2e: keep sientia_data schema and scenario input files.

QTZPOC-20: Refactor ModelImport status engine for lazy initialization, add byte-counted size validation to bundle extraction, optimize MLflow run ID lookups, and ensure workflow cancellation propagates correctly.
QTZPOC-20: Refactor model import workflow, introduce atomic model ID generation, and clarify MinIO expiry.
Fuses bundle download, decryption, MLflow experiment creation, and artifact upload into a single activity to prevent cross-worker issues. Implements an atomic counter for MongoDB model IDs, replacing the max(id) + 1 scan to avoid collisions during concurrent imports. Adds comprehensive documentation for MinIO object expiry mechanisms and refines lifecycle rule application. Improves error handling with clearer responsibility classification and centralizes MLflow repository injection.
QTZPOC-20: Add skip_predict_timestamp flag to model_config to prevent timestamp reinsertion in prediction data, and document other ad-hoc behavioral flags.
QTZPOC-20: Improve structured logging and reporting for all model import pipeline failures by introducing a dedicated activity and centralizing error classification. This ensures consistent observability, with all workflow failures now reported before cleanup. Also, adjusted import step timeouts and refined manual run script cleanup logic.
QTZPOC-20: Implement explicit joblib model flavor and enhance model import workflow with extensive E2E tests.
This commit introduces a first-class joblib model flavor for direct loading and saving of Python pickle artifacts, including custom code within the artifact's code/ directory, bypassing MLflow's flavor loaders. The model import workflow's status database configuration is now streamlined to default to the POSTGRES_* server, with explicit IMPORT_STATUS_DB_* overrides.
Comprehensive end-to-end tests have been added for the model import workflow, covering success paths, gate rejections, digest enforcement, provisioning failures, status record integrity, cleanup, and retry/recovery scenarios using a real-clock environment. New E2
QTZPOC-20: Implement model import workflow for .sientia bundles
Introduces the import_model workflow and its associated activities to enable importing .sientia bundles into MLflow and MongoDB. This includes:
* New core workflow and activity logic for handling bundle download, decryption, validation, MLflow provisioning (experiments, runs, registered versions), and MongoDB model document creation.
* Comprehensive E2E and unit test suites, including a dedicated test harness and a manual run script for development.
* Updated .env.example and README.md with new configurations and usage instructions.
* Ensures correct MLflow model source resolution for legacy loader compatibility and robust MongoDB document management.
* Refactors existing utility scripts into a scripts/ directory.
QTZPOC-20: Implement .sientia model bundle import workflow
Introduces a new Temporal workflow and activities to import .sientia model bundles. This enables:
- Secure decryption and validation of bundles through a seven-gate process.
- Provisioning imported models in MLflow and updating the MongoDB model listing.
- Comprehensive status tracking in the public.experiment_run table with new IMPORT_SUCCESS/IMPORT_ERROR states.
- Dedicated metrics, robust error handling, and configurable settings.
- Includes updated e2e database fixtures and extensive unit/integration tests for bundle format, reader, and overall workflow.
Compares each computed metric against optional per-model thresholds
from model_config.simple_metrics_thresholds. Convention:
- {metric}_max: breach when value > threshold (rmse, mse, mae)
- {metric}_min: breach when value < threshold (r2)
Fires WARNING notification on breach. Missing thresholds = no alerting.
Schema designed to be extensible for Card 2 (Drift) thresholds.
SIENTIAPDE-1986
Replaces manual numpy if/elif chain with RegressionMetrics from
sientia_model. Fixes 3 known bugs in one pass:
- NaN now handled via _align_dropna (was silently propagated)
- r2 zero-variance uses sklearn r2_score (was divergent, pinned at 0.0)
- Unknown metric names raise ValueError (were silently dropped)
Also adds r2 lock: when model_type is known and non-linear,
r2 is excluded from calculation with a WARNING notification.
Drops the now-unused `numpy` import (the manual math it backed is gone,
and no other method in this file references it).
