ctan 56c8970d5b feat(combat): expose threatened squares and movement cost fields for LLM policy 
Rename _threatened_squares -> threatened_squares and
_enemies_threatening -> enemies_threatening (public read-only API for a
future LLM policy), and add reachable_ft(state, budget) and
movement_cost_ft(state, target) accessors returning movement costs in
feet. Pure exposure: no behavior change, resolution engine untouched,
goldens bit-identical.

ctan 82148cea1e test(loaders): add unit tests for combatant feat resolution and feature/spell handling 
Tests for _resolve_feat (known/unknown/Toughness/Weapon Focus),
_resolve_features (filtering, empty lists), load_combatant with
features+spells integration, and backward-compat aliases.

Gate: 401 tests, ruff clean, basedpyright clean.

ctan c88d8fd6f4 refactor(loaders): unify combatant loader, migrate PC features/spells 
Rename monster.py → combatant.py with _KNOWN_FEATS lookup table
that resolves feat name strings to AbilitySpec constants (Power Attack,
Iron Will, Toughness, Weapon Focus, etc.). Unknown feats produce
minimal AbilitySpec (data preserved for future implementation).

Migrate all 8 PC JSONs (data/pcs/) with complete feat/spell lists
extracted from Foundry sheets — including traits, racial abilities,
and all spells. Monsters (goblin, orc) unchanged (no feats/spells).

Update all imports, add backward-compatible aliases (load_monster,
MonsterLoadError), update CLI to use load_combatant.

Gate: 377 tests, ruff clean, basedpyright clean.

ctan e9e8c26d50 feat(loaders): extend Foundry loader with feat/spell extraction 
Map Foundry feat strings to AbilitySpec constants (Power Attack, Iron Will,
Alertness, Point-Blank Shot, Precise Shot, Dodge, Weapon Focus (X)).
Extract spell names from spellcasting.spells into Combatant.spells.
Wire features and spells into load_sheet_detailed return.
Add 41 tests (unit + golden on 8 real sheets).

Gate: 377 tests, ruff clean, basedpyright clean.

ctan 828afc15c0 feat(spells): add spell system with 10 combat spells, cast_spell action 
Spells are SpellSpec dataclasses with typed effects: DamageEffect
(dice + types, half-on-save), ConditionEffect (condition lookup +
save negates), HealEffect (capped at hp_max), BuffEffect (transient
StatModifiers). Range categories (personal/touch/close/medium/long)
scale with caster level via spell_range_ft. JSON loader
(load_spell/load_spell_registry) reads data/spells/*.json.

The engine integrates spells via Action(kind='cast_spell') and
_cast_spell: range check, line-of-effect gate, save resolution
(resolve_save), effect application (_apply_spell_effects with DR
via _apply_dr_for_types), transcript logging. The spell_registry
is passed to CombatEngine; Combatant.spells holds known spell names.

- spells.py: SpellSpec, 4 effect types, SpellRange/SaveType literals,
  spell_range_ft, JSON loader (uses Json type from foundry.py)
- conditions.py: CONDITIONS_BY_NAME registry for condition lookup
- combat.py: cast_spell Action kind, _execute_cast_spell dispatch,
  _cast_spell (range/LoE/save/effects/log), _apply_spell_effects,
  _apply_dr_for_types, _save_label helper, SpellSpec/BuffEffect/etc
  imports, spell_registry parameter on CombatEngine
- models.py: spells field on Combatant
- data/spells/: 10 spells (Magic Missile, Burning Hands, Fireball,
  Lightning Bolt, Acid Arrow, Cure Light/Moderate Wounds, Hold Person,
  Fear, Bull's Strength)
- tests/test_spells.py: 29 tests (loading, range, damage/save/condition/
  heal/buff/DR, out-of-range, unknown spell, dispatch, DC scaling)
- pyproject.toml: PLR0913 ignore for combat.py (CombatEngine.__init__)
- README.md: spells.py architecture section, Sorts removed from
  non-modeled list, 336 tests

ctan 97c0431479 feat(abilities): add Power Attack active feat (-X atk / +2X dmg, melee only) 
Power Attack is the first active feat: a free-action toggle declared at
turn start. When state.power_attack is True and the combatant has the
POWER_ATTACK feature, melee attacks apply -X to the attack roll and
+2X to damage, where X = BAB//4 + 1 (min 1). Ranged attacks are
unaffected. The flag is cleared at the start of each turn via
_take_turn, like other per-turn state.

- abilities.py: POWER_ATTACK constant (AbilitySpec, no passive effects)
- combat.py: _has_feat helper, _power_attack_amt, resolve_attack
  applies penalty to attack total + crit confirm, bonus to damage
- tests/test_power_attack.py: 14 tests (amount at BAB 1/4/8/12, flag
  false, feat missing, attack penalty, damage bonus, ranged unaffected,
  flag cleared on turn)
- pyproject.toml: add SLF001 + RUF059 to test per-file-ignores (white-box
  testing accesses private helpers, partial tuple unpacking)
- README.md: document Power Attack in abilities.py section, 307 tests
