- Fix Allium spec syntax: type→value, enum for Status, remove implies chaining - Fix factions.spec: add missing type declarations (Health, Level, Status) - Fix magical-objects.spec: add type declarations, use .value for Health access, remove entity inheritance syntax, remove invalid invariants - Implement Changing Level: add totalDamageTaken + factionsJoined to Character - Add level-up logic in dealDamage() and joinFaction() - Add Level.damageThresholdForLevel() static method - Fix changing-level.spec.ts properties: handle target survival, compute expected level from threshold crossings
