USR369: "connect them, keep them in the inventory, put links, and Tech will have to go through this and fix them." Backed up frontend/30-Tech/index.html first (D353), then added links for apps/Tech_Library_UI.html ("Tech Library") and apps/android-library.html ("Android App Library" -- temporary label). Read-back + live 200 check confirmed. Added page-inventory.html entries for all 5 kept pages (housekeeping-library, script-library, Tech_Library_UI, navigator, android-library) at n:177-181 -- none had entries before, checked the whole file for the true highest existing n (176) rather than assuming based on nearby entries. Did NOT resolve the real naming collision (android.html already used "Android Library" as its link label) by guessing -- filed T-ANDROID-LIBRARY-NAMING (id 451) to Tech[30] with full detail plus an inbox notice, since deciding whether these should merge or just get better distinct names is a content judgment for the page owner, not something to silently decide.
