-## Snapshot Pipeline Monitoring
-
-Snapshot-backed strategies depend on upstream pipelines. To detect failures:
-
-1. `/probe` checks that required snapshot artifacts exist in GCS
-2. `feature_snapshot_fallback_mode` controls behavior when artifacts are missing
-3. 7-day DCA retry window absorbs transient pipeline delays
-
-## Combo Strategy Pattern
-
-Combo strategies (e.g., `us_equity_combo`) combine sub-strategies. They are:
-- Defined in separate pip packages, imported and merged into platform catalogs
-- Share the parent platform's Scheduler and monitoring
-- Sub-strategy execution handled internally by the combo entrypoint
-- Platform only needs to declare `quant_combo` domain and inputs
