Sub-ticket of MARS-355 /alumnos page renders raw UUIDs in the Comisión and JTP/Ayudante columns instead of human names — violates evolutiva-commons 'no raw IDs/UUIDs in UI/exports'. Surfaced by Elazar 2026-06-30 (duplicate-student screenshot). Fix the /alumnos render path to resolve comisiónId→comisión name and jtpUserId→teacher name (use existing name lookups/views; don't add a new query fan-out if a join/view already serves it). Reversible UI fix. · mars
