What's exactly the condition for race for german achievement?

In order to avoid random that allies naval land near Hamburg, I choose unconventional route. Alt hitstory, goes pan-slavic route.
German opposite hilter, british goes fasicist.
annex TUR, ROM, civil war
Italy join pact of rome, I create faction with GERMAN, France, and carefully not allow GERMAN to join war (by not inviting FRA at last moment)

Annex / puppet all EU land countries, except FRA, GER. annex AUS, CZ, POLAND, since it might have core of GER

Kick FRA out of faction, declare war puppet it. Since GER tend to attack british, finish and puppet england

kick GER out of faction, declare war, and carefully not to call in any puppets. Finish GER alone, no achievement

So on paper, I conquer german after fall of France (although by me) and no core of GER was hold by any other country

People really are struggling with understanding "Fall of France" xD
For me it's pretty clear that it means a historical even after fall of Paris but here you go

limit = {
original_tag = FRA
has_government = democratic
NOT = { has_global_flag = achievement_france_surrender } #might as well use the achievement flag to check if france.10 fired
16 = { is_controlled_by = GER } # Don't fire if someone else is the occupier of Paris
is_subject = no
is_in_faction_with = ENG
has_war_with = GER
}

Basically keep France in the Allies and allow them to die from Germany
