Hi @ManavTheOG 👋 thanks for signing the workbook! The Validate signature check failed. Here's everything to fix in one go:

• Your file must be named exactly signatures/ManavTheOG.md, matching your GitHub username letter for letter (capitals included). Your PR has cp signatures/_template.md signatures/ManavTheOG.md.

How to fix it (in your clone, on the same branch as this PR):

git mv "cp signatures/_template.md signatures/ManavTheOG.md" signatures/ManavTheOG.md
git add -A
git commit -m "Fix signature"
git push

Your finished file should look like this:

# Your Real Name

- **GitHub:** @ManavTheOG
- **Batch:** 2026
- **I'm here to:** your own line
- **One thing I've built:** a link, or nothing yet

Push to this same PR. Don't open a new one. The check re-runs by itself, and a governance reviewer is requested once it's green. Stuck? See Stuck? in the README or ask in the club group.
