How do you debug a detached HEAD issue?

Short answer: A detached HEAD means Git’s HEAD points to a specific commit instead of a branch — commits made now won’t belong to any branch. To fix it: Check what commit you’re on: git status

Real-world example (ShopNest)

ShopNest’s team uses GitHub PRs with reviews and CI checks so broken builds never reach production unnoticed.

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
