Defender-side damage reduction. Highest-wins (multiple sources do not stack in 10e); the dominant source is the one whose value matches the surviving reduction.
Ability-granted invulnerable save. Best (lowest) threshold wins. null
when no ability granted one; the engine still uses the unit's printed
invuln_sv from the profile in that case.
Read-out of a resolved buff stack, with provenance per field.
