DamageEffect gains optional scaling (1dX per N levels, capped) and scaling_flat (+X per N levels, capped) specs; effective_formula resolves them against the caster's level at cast time, so scaled dice flow through crits, energy resistance and metamagic like the base formula (CRB Magic - Caster Level). Loader rejects mismatched die types. Data: Fireball/Lightning Bolt 1d6/lvl max 10d6, Burning Hands 1d4/lvl max 5d4, Shocking Grasp 1d6/lvl max 5d6, Inflict Light Wounds +1/lvl max +5 (SRD-verified). Cure Light Wounds stays flat: its golden transcript pins 1d8+1 and HealEffect scaling is out of scope.

PF1e (APG Evil Eye): the target takes -2 on ONE chosen option (AC, ability checks, attack rolls, saving throws or skill checks) for 3 rounds, and "A Will save reduces this to just 1 round" — it never negates. _hex_evil_eye applied shaken (-2 attack AND saves) for 1 round with the save negating entirely. It now adds a targeted -2 attack ActiveBuff for 3 rounds, or 1 round on a successful Will save. Simplification documented in README: the option choice is not modeled (attack rolls are the engine's target). The hex-DC behavioral test now reads the -2 attack (3r) transcript line.
