   **Root cause 4 (fix landed 2026-04-25):** `combat_resolver.gd::_get_ranged_attack` and three `combat_preview.gd` callsites called `unit.get_damage()` and `unit.get_damage_resistance()` — methods that don't exist on `Unit`. The `unit.gd` only has `get_attack()` and `get_defense()`. Each game produced ~300 SCRIPT ERROR lines per game on huge-map runs (combat-heavy). Verified in `huge-map-5clan-20260425_021822/game_*_seed4/game.log`: 305 errors, primarily `Invalid call. Nonexistent function 'get_damage' in base 'RefCounted (Unit)'`. Fixed: changed all 4 callsites to `get_attack()` / `get_defense()`. Verification batch `p0-22-noerror-*` running on apricot.
