v3 no less!
You can look at the time for first commit (only commit here) and compare it to the time it was submitted to HN. The fastest I had seen before today was 25 minutes.
The pattern you seen in these is
1. Single commit to GitHub
2. Create HN account
3. Make HN post
You can find skills for project promotion that include HN.
In this case, I think the "v3" is to try and bypass some of the filtering, to suggest the project has more maturity than the likely fresh vibe coded output it is.
Your git project should have history. Your claims about working on it for T time are unverifiable. You should `git init` before any code is written.
