- MagicalObject: internal #health and #maxHealth now Health type
- HealingObject: constructor, create, and heal use Health value object
- MagicalWeapon: constructor, create, and use use Health value object
- DamageDealer and Healer interfaces: health: number -> health: Health
- magical-objects.spec.ts: all assertions use .health.value
- Run npm run checks: 0 errors, 70 tests passing
- Create src/magical-objects/magical-object-types.ts with DamageDealer
and Healer interfaces
- MagicalWeapon implements DamageDealer
- HealingObject implements Healer
- Character depends on interfaces instead of concrete classes
- MagicalWeapon: fixed damage, owner-only, self-destructs at 0 HP
- HealingObject: heals characters up to both caps, self-destructs at 0 HP
- 18 fast-check properties covering rules and invariants
- Allium spec with entities, rules, and invariants
- Character.createWithHealthAndStatus factory method for status-aware creation
- dealDamage returns new Character instead of mutating in-place
- SelfDamageForbidden uses reference equality (this === target)
- Negative damage throws at the boundary
- Removed duplicate Health.maxHealthForLevel (Level.ts is source of truth)
- Allium spec uses max(0, ...) for health floor precision
- New property: NegativeDamageForbidden (11 total properties)
- Allium spec: damage-and-health.allium
- 5 fast-check properties: damage reduces health, health non-negative,
death at zero, self-damage forbidden, dead cannot take damage
- Character.createWithHealth factory for testing with arbitrary health
- Character.dealDamage(target, damage) method
- Level value object (1..10, level-capped health)
- Health value object (non-negative, pure sub/add)
- Status discriminated union (alive | dead)
- Character entity with private constructor and static factory
- 9 fast-check properties covering creation invariants
- Allium spec with entities, rules, and invariants
