 ### Layering
 - **`orchestrator/worker/worker.py`** — entrypoint (`python -m orchestrator.worker.worker`). Builds a single `Activities` instance, connects to Temporal, starts Prometheus (`HTTP_METRICS_PORT`) and Temporal SDK metrics (`HTTP_SDK_METRICS_PORT`) servers, then runs three `Worker`s concurrently via `asyncio.gather`, each on its own task queue: `orchestrator-queue`, `alerts-queue`, `reports-queue`. `prepare_worker.py` derives the queue name from the workflow class name (`camel_to_snake`) and reads per-queue concurrency/poller tuning from env vars prefixed with the workflow name (e.g. `ORCHESTRATOR_MAX_CONCURRENT_ACTIVITIES`).
-- **`orchestrator/workflows/`** — Temporal workflow definitions: `orchestrator.py` (pipeline/slot/schedule orchestration), `alerts.py` (real-time ERROR notifications), `reports.py` (scheduled all-level reports). `alerts.py` and `reports.py` both delegate to the same two subworkflows in `workflows/subworkflows/`: `load_notification_package.py` (load notifications + receiver configs from Mongo, incremental via Redis timestamp) and `process_notifications.py` (build HTML email, send, log to Postgres). The difference between alerts and reports is which filter activity they call (`filter_notification_alerts` vs `filter_notification_reports`) and their base data filter (`level: ERROR` vs all levels).
+- **`orchestrator/workflows/`** — Temporal workflow definitions: `orchestrator.py` (pipeline/slot/schedule orchestration), `alerts.py` (real-time ERROR notifications), `reports.py` (scheduled all-level reports). `alerts.py` and `reports.py` both delegate to the same two subworkflows in `workflows/subworkflows/`: `load_notification_package.py` (load notifications + receiver configs from Mongo, incremental via Redis timestamp) and `process_notifications.py` (build HTML email, send, log to Postgres). The difference between alerts and reports is which filter activity they call (`filter_notification_alerts` vs `filter_notification_reports`) and their base data filter (`level: ERROR` by default vs all levels) — `load_notification_package.py`'s `_compute_query_time_filter` can widen either beyond that default to the union of active receiver groups' own `levels` (SIENTIAPDE-2011); the ERROR-only default only holds when no active group narrows further.
 - **`orchestrator/activities/activities.py`** — `Activities` is a single class combining every activity mixin via multiple inheritance: `TemporalManager, SlotManager, Formatters, MongoDB, Email, Postgres` (Postgres comes from `sientia_do.temporal.activities.postgres`, the external `sientia-dataops-library` dependency). One instance is constructed in `worker.py` and its bound methods are handed to each `Worker` as the activity list — activities are plain methods on this shared object, not separate classes. Each mixin's `__init__` takes its own config dict plus shared `logger`, `notification_handler`, `metrics_controller`. `Activities.shutdown()` closes every mixin's connections.
 - **`orchestrator/utils/`** — `connectors_config.py` builds each config dict from env vars (Temporal/Redis/MongoDB/Postgres/Email); `email_builder.py` renders Jinja2 templates (`utils/templates/email_template.html`, `general_template.html`); `orchestrator_functions.py` transforms pipeline documents into pipeline-type-specific configs (`scouter`, `pi_web_api_scouter`, `predictions_batch`, `minimal_retrain`, `drift`, `simple_metrics`); `converters.py` handles Temporal schedule frequency parsing.
