Decision:
- decision_class: TA9_SHADOW_NONINTERVENTION_VERIFIED_OOS_COLLECTION_READY
- P1_implementation_allowed: false
- real_exit_implementation_allowed: false
- shadow_logging_deployment_allowed: true
- shadow_logging_deployment_scope: STRATEGY_TESTER_OOS_ONLY
- out_of_sample_shadow_collection_allowed: true
- production_shadow_deployment_allowed: false
- demo_forward_shadow_logging_allowed: false
- live_real_money_shadow_logging_allowed: false

Reason for OOS_READY instead of full VERIFIED:
- Non-intervention and snapshot integrity passed.
- Recovery eligibility TRUE branch was not observed in these six in-sample runs.
- Actual close join remains proxy-only because broad order-result hooks were intentionally not added.
