s5.kit.heal was Rust's November 2026 build: a player-only item (the syringe) has a held entity only in the belt (ItemModEntity.playerOnlyEntityBeltOnly), so RunicNPC's heal found nothing. D331 records the fix the org lead chose: every kit extra is found by its item definition when it has no held entity. s5.fight.shootBack was the harness: a cliff rock between the fifth fight's pair on the drill's 3500 map. s5.fight.leash (run 49, left out of the 9c note) did not come back in three tries; the likeliest way in and the harness's new note are recorded, and the rule stays until a failing run says which.
