At certification the CAC runs the zone checks (4.2 rows 34, 35, 17, 18), the digests (row 2), prefix uniqueness (row 14), atomicity of assumptions (row 23) and regime assignment (row 19), then checks every record against the register and the master record (4.1.2) and applies SR3 to SR6 (rows 20, 21, 22, 24). All passing yields the candidate certificate (5.5.3); a contradiction yields a withdrawal record (4.6.1); equal distance, a reached N_x or a gold-standard case opens an audit block ending in a decision item (4.1.5). A rejected component returns to its author (5.5.2).
