This sounds like the pacts would slow down alicorn production, thus consuming alicorns instead of necrocorns. However, my necrocorn rate remains slow, as if my pacts are still consuming necrocorns.

My reading of the code makes it sound like there is only necrocorn consumption if the Siphoning policy is chosen, and alicorns are not affected either way. Aside from the necro fast forward code, this is the only place siphoning appears:

getCorruptionPerTickConsumption: function()
{
    if(this.game.getFeatureFlag("MAUSOLEUM_PACTS") > 0 && this.game.science.getPolicy("siphoning").researched)
    {
        return this.game.getEffect("necrocornPerDay")/this.game.calendar.ticksPerDay;
    }
    return 0;
},

getCorruptionDeficitPerTick: function()
{
    return Math.max(-this.getCorruptionPerTickProduction() - this.getCorruptionPerTickConsumption(),0);
},

getCorruptionPerTick: function(pretendExistNecrocorn)
{
    var corruptionProduction = this.getCorruptionPerTickProduction(pretendExistNecrocorn);
    if(this.game.getFeatureFlag("MAUSOLEUM_PACTS") && corruptionProduction > 0 && this.game.science.getPolicy("siphoning").researched)
    {
        corruptionProduction += this.getCorruptionPerTickConsumption();
    }
    return Math.max(corruptionProduction, 0);
},
