Three small UX/fairness tweaks from manual live testing: 1. Post-submit "wait for reveal" screen: show only the response time, no score. The +score reveal leaked correctness — any positive number = correct, zero = wrong — short-circuiting the "stop and think" beat the reveal pause was supposed to enforce. Time stays as the engagement signal; score now waits for the instructor reveal. 2. Final-screen "Correct X / Y" denominator is now total_questions instead of questions_answered. Missed questions are scored zero, so they belong in the denominator visibly. Server adds total_questions to the session_ended payload. 3. Projector score-distribution: drop the in-chart count labels (they collided with each other and with the median tag at small N), restore the previously-computed-but-not-rendered x-axis tick labels at the bottom. Stats line at the foot keeps n / mean / max. Also: short-circuit the per-submit instructor + presence broadcasts when no instructor / projector is connected (no listener, no DB work). The 50-student load test was tight on margin against its 2 s time_limit; with the new presence_message / live_histogram_message DB queries firing on every submit, the margin disappeared on busy boxes. Conftest fixture also bumped to 8 s per question for the same reason — gives breathing room for sequential WS submits in the load test. 71/71 pytest green.
