Paper read

Any task, in any project, that needs what a library paper says gets it fast from the paper's paper note, with sources to check it against the PDF, instead of reading the paper again. Two things hold this knowledge:

• The paper note, in Zotero under the paper's item, one per paper: the paper alone, what it says and judgements about it (references/note-format.md).
• The project's paper index, in the project: one line per decision the project based on a paper, pointing at the note's question and the project's own reasoning (references/notes.md).

The subject decides where a sentence goes. About the paper → the note, whether or not a project needs it. About a project → that project.
