I like this but I have several questions. Sometimes options like funding the Reichsbanner, building loyalty in the police, using the leftist minister to boost relations with KPD or using the card (not minister) to boost coalition do nothing. With police I understood that you can't boost loyalty past mostly loyal is impossible but many others are seemingly function (or not) at random. To be more clear: they mostly function but couple of times it didn't function

You can boost loyalty for both the Prussian and Internal police from 'Mostly loyal' to 'Generally loyal' and then 'Completely loyal'. It doesn't seem to function because the differences between the categories can't be bypassed with only one 'Improve loyalty' action, instead you need multiple. This applies for all the items in your list including boosting relations, building loyalty and funding the Reichsbanner.
You don't see the bar progression, but from divided to -> mostly loyal, you just do 1 loyalty, then from mostly loyal -> generally loyal, it generally needs 3 boosts/purges. Going completely loyal is useless in the long-term, mostly just aesthetic.
Generally loyal Prussian bulwark is more effective when you ban the SA, though I recommend you just do "boost loyalty" 2-3 times, then switch to recruiting, which gives 20k more men per recruitment, making them more effective when you try to arrest and deport Hitler, or when the SA disrupts your rallies.
Speaking purely from experience, I actually don't know the metadata.
