final_final_REAL.zip is a confession
You have seen the folder. report_final.docx, report_final_v2.docx, report_ACTUALLY_final.docx, and the closing argument project_final_v2_REAL_USE_THIS.zip. That naming scheme is not a workflow. It is a confession that the project has no memory and the human is the memory.
A backup tool answers can I recover this file? Git answers a different question: how did this project become what it is, and can I move safely through that history? A real project is a web of source files, configs, generated artifacts, experiments, bug fixes, and decisions. Git gives that web a timeline you can walk forwards, backwards, sideways into a parallel universe, and back.
That is why the rest of this quest is not a list of commands. It is a model. A commit is a named checkpoint for the whole project, not just a save of one file. A repository is a history database that lives next to your working files in .git/. GitHub is useful, but Git itself is local-first — you can commit, branch, diff, blame, and recover without the network. If you finish this lesson with one upgrade, let it be this: stop saving copies, start writing history.
