Sources: the 4 Duncan playbook memory files (master + DV-DU + DT-DS + DR-DQ chunks) and the 16 Wave 1-4 commits on `main`._ The reels are the source of truth for "what Duncan ships." The commits are the source of truth for "what we ship."

Corpus pages are public-safe readers for discovered workspace artifacts. They are not automatically final papers. A corpus item becomes a polished paper only after the editable source, evidence checkpoints, references, figures, render path, and release status are attached through the paper schema.
