selected_plan: TA9_SAFE_DISTANCE_TO_HARDSTOP_NONNEG
decision_class: TA9_DESIGN_REQUIRED
P1_implementation_allowed: false
reason: TA9 has the strongest effect and the HTE Kill can be removed by a real-time field filter, but implementation still needs a POST_HEDGE_SLOT / priority-order design decision before P1.
required_runtime_slot: POST_HEDGE_SLOT or explicit Pre-HardStop slot with shared ClosePriority snapshot
priority_order_change_required: true
HTE_kill_count: 0
HTE_kill_yen: 0.00 after TA9_FILTER_DISTANCE_TO_HARDSTOP_NONNEG (TA9 raw HTE kill was 70.00)
executable_net_effect_yen: 32830.00
TA5_advantage_or_disadvantage_yen: 12767.00
TA4_advantage_or_disadvantage_yen: 18827.00
additional_logging_required: yes; runtime candidate logs must include distance_to_hardstop_yen, hte state, priority_snapshot_id, eval_stage_index, and same-tick ClosePriority state
next_action: Design-review TA9 safe filter in POST_HEDGE_SLOT. If priority-order change is not accepted, move to TA5 as safer fallback.

Reference raw plan comparison:
- TA9 raw net: 32760.00; HTE Kill 1 / 70.00 yen.
- TA5 net: 20063.00; HTE Kill 0.
- TA4 net: 14003.00; HTE Kill 0.
