For example: ``` class Book { readonly canBeDraft = newAsyncProperty("reviews" => b.reviews.length === 0) } class Author {} authorConfig.addRule({ "currentDraftBook:rx": "canBeDraft:rx" }, a => { if (!a.currentDraftBook.canBeDraft.get) { return "Book...

I.e.: ``` const [projectStage, location] = await Promise.all([ selection.load((hs) => hs.projectItem.projectStage), selection.load((hs) => hs.projectItem.location), ]); ``` Could be: ``` const [projectStage, location] = await hs.load( (hs) => hs.projectItem.projectStage, (hs) =>...

Look into transaction conflicts

Explore queries issuing in parallel

I.e. so that: ```typescript const tasksByDefinitionId = target.stages.get .flatMap((s) => s.units.get) .flatMap((u) => u.activities.get) .flatMap((a) => a.tasks.get) .filter((t) => t.taskDefinition.isSet) .mapToObject((t) => [t.taskDefinition.idOrFail, t]); ``` Could be: ```typescript const tasksByDefinitionId...
