`min_max_range` took one `target_reach` that served two roles: the melee arm's fallback to the auto-attack target and the ranged arm's explicit target. The ranged arm padded whenever it was `Some`. The tooltip passed the auto-attack target's reach, so while you swung, every ranged spell's tooltip read its row plus both reaches: Fireball read "38 yd range" where 1.12.1 reads 35.
`GetMinMaxRange 0x6e3480` counts its target (`[ebx+0x10]`) only when it is a unit (`0x6e34e1`-`0x6e34f9`).
- **Melee arm** (`0x6e3552`-`0x6e3594`): with no unit target, it falls back to the caster's auto-attack target (`0x6e356a`), then to the caster's own reach.
- **Ranged arm:** pads only for a non-null target (`0x6e35d8`, `0x6e35ec`). The max always takes the pad, and the min only when nonzero.
What each caller passes:
| Caller | Call site | Target |
|---|---|---|
| Tooltip | `0x52e9c2` | none |
| `ActionHasRange` | `0x4e5852` | none |
| The cast check and `IsActionInRange` | through `CanTargetUnit 0x6e4440` → `0x6e47b0` | the bound or selected target |
Changes:
- `min_max_range` takes `RangeTargets { target, attack_target }`.
- The melee arm reads the target, else the attack target, else the caster. The ranged arm pads for the target alone.
- Each caller passes what its reference call site passes. The action button's two verbs are now two calls: `has_range` with no target and `in_range` with the selected one.
- `min_max_range_reads_reach` narrows to melee rows. The tooltip safety net then counts 813 reach-dependent views instead of 10,298, so starting to swing no longer rebuilds every ranged tooltip.
Tests:
- `ranges.rs`: `the_ranged_arm_pads_only_for_the_explicit_target`, `the_melee_arm_falls_back_from_the_target_to_the_attack_target_to_the_caster`, and the narrowed exactness test.
- `range_cell_on_real_data` reads Fireball as "35 yd range" and Charge as "8-25 yd range" with an auto-attack target present.
- `cast_range_refusal_follows_the_two_compares` covers a bound target's pad.
- `a_ranged_button_pads_its_range_by_the_selected_target_alone`.
