Local API stress (lib.mjs / api_stress.mjs): - setupSession now does login -> /admin/api/reset and returns sid="main". Drops the dead /admin/api/quizzes + /admin/api/sessions calls left over from the multi-quiz codex era. - bootServer writes the fixture pool (STRESS_POOL by default) to a tmp file and passes QUIZ_POOL_PATH so the v1.2 server has a session at startup. - happyPath: drop the post-connect lobby_update wait (race with snapshot dispatch) and stop double-driving the lifecycle (next() already opens the next question, an explicit open() afterwards is a no-op). - cross_session: rewritten as "cookie not honored on a non-existent sid" since v1.2 hosts a single canonical session. Live accuracy stress (live_accuracy.mjs): - Per-student lobby-snapshot timeout (12s) with WS error/close rejection, so a stalled handshake no longer hangs Promise.all until the outer shell timeout (which produced the exit=124 cycles). - Open all student WSs in parallel (mirrors what real students do); the batch-of-8 throttle was masking the question we wanted answered. - Instructor WS open also bounded by a 15s race so any failure surfaces as actionable error text instead of a silent stall. Bootstrap (deploy/bootstrap.sh): - Stage 1 provisions a 2GB swap file (idempotent) with vm.swappiness=10. 1GB-RAM ECS instances OOM-kill uvicorn under WS-burst start-of-class pressure; swap absorbs the spike without affecting steady state. - Pool seeding prefers examples/demo10_pool.json over the 2-question example so a fresh deploy boots with a usable demo. Pool fixture (examples/demo10_pool.json): - 10-question generic-knowledge demo pool, gitignore exception added.
