Feature/lab2

[G-Akleh]

Goal

Solves lab 2 for the DevOps course repository

Changes

• Tag v0.1.0-lab2-Ghadeer created with -a -s flags (annotated + signed)
• Pushed to origin successfully
• Verified with git tag -v showing "Good" signature ✓
• Simulated upstream moving with an empty commit on main
• Rebased feature/lab2 onto origin/main (3 commits replayed cleanly, no conflicts)
• Pushed with --force-with-lease for safety
• Captured before/after graph showing linear history
• Documented when to choose rebase (solo branches, before PR) vs merge (shared branches, preserving history)
• Explained why rebase was correct for this scenario

Testing

• Verified object model with git cat-file on main
• Checked recovery WIP commits via git reflog + git reset --hard
• Verified tag with git tag -v → Good "git" signature; pushed tag to origin
• Checked rebasing feature/lab2 onto local main after simulated upstream move; pushed with --force-with-lease

Checklist

• Title is a clear sentence (≤ 70 chars)
• Commits are signed (git log --show-signature)
• submissions/labN.md updated
