Continuing the backend audit: systems/30-tech/index.php (the backend Tech landing page) had an 'Apps' quick-access link pointing at systems/30-tech/apps/index.php -- a placeholder scaffold from 07/12/26 that was never populated ('No apps listed yet -- build out links here as apps are completed'), despite 11+ real apps existing in that exact directory now, all properly indexed on frontend/30-Tech/index.html. Anyone clicking 'Apps' from the backend hub was landing on a misleading dead end. Fixed by pointing the link directly at the real, actively-maintained frontend hub instead of duplicating a second app list that would need separate upkeep. Also noticed (not fixed, flagging only): the adjacent 'Internet' quick-link on the same page is a literal href="#" stub that goes nowhere -- purpose unclear, left alone per 'ask don't guess' rather than assuming what it should link to.
