Must <foreign_model>_id be fillable to save it on resource creation?

I have two models, Opportunity -> belongsTo -> Company. The opportunities table has a company_id field which is * not nullable* to ensure data integrity. The Opportunity model has a relationship company.

class Opportunity extends Model
{
  protected $fillable = [
    // attributes of Opportunity, WITHOUT `company_id`
  ];

  public function company(): BelongsTo
  {
      return $this->belongsTo(Company::class, 'company_id');
  }
}

Note that company_id is not included in $fillable, as other sections of my app outside the Filament admin panel should not be able to alter this relationship through requests.

My OpportunityResource::form field for the relationship:
Forms\Components\Select::make('company_id')
  ->label('Company')
  ->relationship(name: 'company', titleAttribute: 'name')
->required(),


On the EditOpportunity page, I can alter the associated company just fine. On CreateOpportunity however, I can select a company but I get this error:
SQLSTATE[HY000]: General error: 1364 Field 'company_id' doesn't have a default value


If I add company_id to Opportunity::$fillable, it works as expected.
I'd expect consistent behavior between Create and Edit, so either require company_id in $fillable on both operations or on neither.
