Sub-ticket of MARS-23 Ayudante grading-responsibility = NONE (Elazar policy B): ayudantes must NOT count toward sin-calificar NOR receive grading nags. getJtpStats pending/sin-calificar axis -> JTP (assignedTeacherUserId) ONLY (drop ayudante CROSS JOIN from that axis); weekly-kpi grading nags -> JTP only; drill auto-follows getJtpStats. Acceptance: Belén Montoya bcd98024 (pure ayudante) shows 0% sin calificar; no ayudante gets a grading nag. Fixes both Belén-100% + Florencia-nag complaints. · mars
