A DRAFT UWC page passes its zone checks into a CANDIDATE CERTIFICATE on staging (5.5.3), which H-DECL lands as a DECLARATIONS line (5.5.4); TPX verifies each build against it on the BUILD CHAIN page (5.6.1) and instantiates the container's MANIFEST, whose BADGE is written last (5.10.1). The CENTRAL HUB reaches LIBRARY PAGES and manifests (5.11.7). Each container has a LOCK page (5.7.2), a COLLABORATION page with PETITION rows in revision order, ASSIGNMENT rows written by the lead and RETURNS on staging subpages (5.8), and a CONTROL PANEL with its SCHEDULE LOG and WORK-BLOCK LOG (5.9.2, 5.12.1). TPS is the instruction artifact whose digest is D(IS); IMPLEMENTATION entries conform to it (5.11.4, 6.1).
