Understanding したことまで


The speaker is defending her teacher:

> 「毎日クラス全員のこと、こまかくノートに書いてるんだよ。 **会話したことまで** 」  
>  Every day, in her notebook, she made detailed notes about all the class.
> _Even as far as conversations._

Am I correct that verb-ことまで means "to go as far as doing verb"?

I'm not 100% sure about the verb here. Is した just a substitute for 書いた? i.e.
is it talking about writing down the conversations, or is it talking about the
act of conversing itself?




した in 会話した is simply a part of the suru-verb 会話する ("to converse"), which is an
intransitive verb that does not take を.

If we took this こと after 会話した as a nominalizer, this would mean "She writes
even the fact her classmates conversed", which makes almost no sense to me.
The mere fact that "students made a conversation" is not a meaningful piece of
information because students do so every day.

So I think this こと simply is "things", and 会話したこと means "the things we
conversed _about_ ", or "the contents of our conversations".

Relative clauses in Japanese can have an adverbial relationship with the
modified noun (Type B in [this
question](https://japanese.stackexchange.com/q/39551/5010)), and can be safely
used with intransitive verbs.

Examples:

>   * よく行く場所 the place we often go _to_
>   * 何か書くもの something to write _with_ (eg, a pen)
>   * 何か書くこと something to write _about_ (eg, an event)
>   * 感謝の気持ちを表す言葉 words _with_ which I can express my gratitude
