Deferred: CombatantState has no temporary-hit-point track (temp HP must absorb damage before real hp, not affect the dying/dead thresholds, and expire on duration - a cross-cutting change to every damage site), so no mechanical effect is applied."

Modeled as a TempHpEffect (amount 1, 10 rounds): temporary hit points absorb damage before real hp (CRB 'Temporary Hit Points'), expire when the granting effect's duration ends, and do not stack (the creature keeps the higher amount, ties keep the longer remaining duration). default_policy never casts it: cantrips have no spell slot, and _find_buff_spell skips level-0 spells, so Virtue cannot preempt a leveled buff (Divine Favor) in the known-spell order."
