There are questions about whether code casts are allowed or not. I have decided that, yes, you may enable code casts in any% for all categories that you can choose your code cast before playing.

What does this mean?

You may go back into your flame poem chapter for the Orchid Words and change your Code Cast before starting Orchid Words and using them for side stories.

Why did I make this decision to allow it?

Because it would invalidate speed runs that old mods have already approved.

Install Skills?

Because of the ability to gain bond through extra missions, for the side stories, you can gain bond. For any% sidestories, you may not apply install skills; only in NG+ any% may you put install skills in side stories.

Though I am willing to listen to feedback about this topic.

Thanks for setting clear rules about code casting.

I support that decision as well.
The reason is that Code Casts can only be earned up to the start of that story, but Install Skills can be earned as much as you want before then.(DeepL)
