[Avodah] Eruv Tavshilin - Shavuos Erev Shabbos

[Micha Berger]

I am pretty sure we discussed this in the past, but I couldn't find it
in the archive.

Today's eruv tavshilin is a rarity as Friday is Yom Tov mideOraisa. We
are permitting hakhanah on YT deOraisa for Shabbos.

I was wondering how eruv tavshilin works in this case. Why isn't it
ha'aramah?

Tir'u baTov!
