From your keyboard to the vault
A contribution is anything you know that your class does not have yet. It goes through four steps, and you decide at every one of them.
The loop
Type what you remember, attach a photo of the whiteboard, paste a link. No formatting. It does not have to be neat.
Your note comes back with a title, a summary, a clean body, and a suggested section. Your original sits right beside it, untouched.
Change anything you like, the title, the structure, every word. What comes back is a draft of yours, not a decision made for you.
Nothing reaches the class until you press share. Until then it is a private draft only you can see.
Shared notes carry their contributors. When a correction goes through, the person who wrote the note and the person who fixed it both appear in the version history, and they stay there.
Your run of days is yours alone. Nobody else sees it, where you stand in a class is shown only to you, and after a quiet week it shows the run you already managed instead of a zero.
After sharing
Anyone in the class can propose a fix to a shared note, with a reason and sources. A maintainer reads it and decides. Nothing changes without a person choosing it, and the old version stays where it is.
