Retired the last remaining confirmed-dead items: 4 pre-migration temp/ library files (LIBR_Android/Windows/Definitions_Tech + Tech_Library_UI.jsx, all confirmed unreferenced anywhere via full-snapshot grep before touching) and the qa_seed_boot.php/qa_seed_exec.php one-time DB seed pair -- handled these last two with extra care since qa_seed_exec.php contains a live DELETE FROM qa statement, so both were fetched and retired via read-only file-editor.php + direct content write only, never a live GET, to avoid any risk of accidentally re-triggering a data wipe (learned from the earlier self-deletion incident this session).\n\nFULL LINK AUDIT: extracted every href from the 19 live Tech[30] pages (frontend hub + all 10 apps/ pages + all 6 php-ed/ pages + the systems/30-tech backend hub + laboratory/apps-hub.html) -- 142 link instances, 57 unique internal targets after dedup. Checked live HTTP status on all 57. 5 initially flagged as 401 turned out to be a false positive in my own check script (file-editor.php links correctly require a token param, which my automated HEAD/GET check omitted) -- confirmed with the token, all 5 return 200. Real result: all 57 unique links across all 19 pages are live and working.\n\nPAGE-INVENTORY UPDATED: systems/30-tech/index.php entry (n:27) updated to reflect the Apps-link fix and link-audit result, status MINOR->DONE. Added 4 new entries not previously tracked: backend/369/index.html (n:184, the rebuild), and win-scripts.php/server-scripts.php/android-scripts.php (n:185-187, the token+title fixes) -- these 3 render live HTML pages but had no page-inventory entry before today.
