Cleared open task queue 16->3. Fixed live security exposure (K351, backend/tools/critical/ open directory listing + downloadable browser-history.db). Fixed silent-param-loss routing bug (K350, add_task assigned_to vs to_system). Fixed 2 stale gov docs (LEGACY-STANDARD.md, BACKUP-REG.md). Ran first decision audit -- found 544/776 decisions with blank D-codes plus 10 genuine code collisions, filed T00-DUPCODE. 2 tasks remain, both need USR369 clarification (T721, T2512).

6 tasks closed directly, 5 routed to Server[40], 1 security fix deployed+verified, 1 routing bug fixed, 2 gov docs corrected, full decision audit run, D763 logged.
