eduKateSG · DEEP READING INDEX · QUIET ROUTING LAYER
Deep Reading Index
This is the quiet safety-net underneath the eduKateSG knowledge system. Normal reading should begin in a subject or system hub. This index exists so older, specialist and deep pages remain reachable even when they do not belong in the main navigation.
Start with Learning Hubs for school learning, Education for the larger learning system, World & Knowledge for wider knowledge systems, or the eduKateSG Ecosystem Atlas for the current owner map and decade-scale roadmap. Use this index when you deliberately want older, specialist, experimental or long-tail material beyond those normal routes.

Routing rule: use hubs for meaning; use this index for completeness. A deep page should remain discoverable without forcing the main menu to carry the entire library.
Return routes: use Learning Hubs for the normal subject-facing map, World & Knowledge for connected disciplines, Research & Inquiry when evidence and uncertainty are the issue, Civilisation for the longest system view, HELP when the next route is unclear, or the eduKate Ecosystem Hub when the correct federation owner is the question.
