Living Word — UGC Phase 1A (educator-authored quizzes, private visibility)
Phase 1A of Living Word UGC — shipped educator quiz authoring at /living-word/educator/*, the lw_ugc_quizzes + lw_ugc_authors + lw_classrooms (stub) + lw_ugc_quiz_audit_log schema, the synchronous regex + asynchronous semantic moderation pipeline, the 13-rule UGC hard floor (rules a-m) enforced at submit time, and the in-game pool merge for private-scope quizzes. Phase 1B (school-pool visibility) and Phase 1C (public-library publish) deferred per spec §10.
