PLUTO-136 PLUTO-133 follow-up (Elazar 5b, sequenced AFTER the main toast sweep ships): should-be-required / data-integrity candidates needing a verify pass then fix — (1) periodo date-range fechaFin<=fechaInicio unvalidated client+server; (2) practica rejection comentario not required; (3) destructive activo toggles (periodo/comision) no confirm dialog → toggle-off cascades; (4) admin create-user with no role → primaryRoleId NULL → blank-redirect login. Verify each path first (2nd-sweep agent guessed some), then fix. Do NOT start until PLUTO-133 main sweep is shipped.
