btrfsck was created in April 2007. Btrfs was merged in 2009.

I can't find a related commit in btrfs-progs from before 2013. Could you provide a reference?

I vaguely member asking Chris Mason about said tool at a SCALE talk in the early 201Xs. There was no fsck at that time and it definitely was not "in the wild" when btrfs was merged.

That was probably late 2011/early 2012, there was a lot of buzz about btrfsck. With the announced enterprise support by SUSE and Oracle the question about fsck was frequent. There was fsck code in git and admittedly missing some features, but not really non-existent. In February 2012, some important repair features landed and since then lot of improvements have been added.
