Every sentence knows where it came from
You export an authorship report alongside the thesis. The record is append-only, so nobody can change what it says afterwards, including us.
A reference you cannot check is not a reference
Every source comes back from Crossref, OpenAlex or Semantic Scholar carrying an identifier. If it did not resolve, you never see it.
It works with no connection
Your chapters, your sources and your reference library are on the laptop. What you wrote goes up when you are back.
