Next decision

Do not start P1 implementation directly from this package.
Next action: human/design approval for TA9_SAFE_DISTANCE_TO_HARDSTOP_NONNEG in a POST_HEDGE_SLOT or equivalent pre-HardStop evaluation slot.
If priority-order change is not acceptable, TA5_DISTANCE_HS_1500_HTE_NOT_NEAR is the safer P1 fallback.
TA4 remains the conservative fallback but is weaker and 50k-biased in this six-log sample.
