Hierarchical descriptor structure
Verified against extracted text and rendered PDF during complete review; locator is the PDF sheet number in the canonical local copy.
Capture evidence faithfully. Select one Source, record a usable locator, and preserve enough surrounding context to prevent misquotation.
Evidence
Paste the exact quote, paraphrase, statistic, definition, or source claim into Excerpt Text. Use Excerpt Type to distinguish quotation from interpretation.
Location and context
Record Locator Type, Locator Start, Locator End when needed, and Source Section. Explain the surrounding argument in Context.
Annotation
In Annotation, state why this evidence matters. Add approved Tags for retrieval and connect it to every relevant Literature Note.
