The developer just "cleaned up the code comments", i.e. they removed all TODOs from the code: https://github.com/nkuntz1934/matrix-workers/commit/2d3969dd... Professionalism at its finest!
I also use this as a simple heuristic: https://github.com/nkuntz1934/matrix-workers/commits/main/ There exist only two commits. I've never seen a "real" project that looks like this.
You don't need to see every single commit and the exact chronology of my work, snapshots is enough :)
