The spine is the survivor. The corpus is the record around it — live systems, validation sleeves, research still being tested, and rejected ideas kept visible because failure is evidence.
These repositories have progressed far enough to enter LABS. LIVE indicates the governed spine or live path; VALIDATION indicates active work that has not yet earned the production bar.
Research, Concept, Null, and Rejected repositories remain part of the public record even when they do not qualify for LABS. The full organization view is the authoritative inventory.
