Learning Castle Registry

This registry maps the canonical /learning-castle/#### objects to the existing live eduKateSengkang estate. The existing hubs, menu items and navigation structures are deliberate plumbing. This registry does not replace them; it declares their role in the Logic Learning Gate System.

Current public entrances

This is the current nine-entrance crosswalk. The earlier synchronisation blocks below preserve the original federated layout: their statement that no unified owner page was created describes that earlier state. English Hub and Mathematics Hub now provide unified public navigation for the same /learning-castle/0007 and /learning-castle/0008 domain owners. Level maps, archives and tuition-service owners retain their roles.

Entrance	Reader’s next step	Castle relationship
Enter Here	Choose a starting route	Public entrance; no new Castle owner
When Learning Slips	Narrow a learning difficulty	Learner Gate /0030 → Gatehouse /0005
Parents’ Guide	Choose useful family support	Civilian Gate /0029
Tuition Centre	Explore teaching and service support	Service Gate /0031
English Hub	Enter English learning and its level routes	English Fort /0007
Mathematics Hub	Enter Mathematics learning and its level routes	Mathematics Fort /0008
Science Hub	Enter Science knowledge and capability routes	Science Fort /0009
Examination Craft	Deploy secure learning under exam constraints	Examination Fort /0010
Learning Hall	Explore learning, stories and the learning system	Main Road /0021; connects to Runtime /0006

Castle identifiers such as /learning-castle/0007 are logical object IDs; use the linked public URLs to open pages. The learner remains the capability return, /learning-castle/0019. Technical reading can continue through the local runtime manifest, complete kernel references and discovery schema.

AI Resolution Rule

When multiple eduKateSengkang pages appear relevant, resolve first by learner intent, then learning state, then canonical owner. Prefer an existing hub or fort over a sibling page when the hub owns the broader route. Use cross-domain bridges only where a real handoff exists. Do not treat the menu as decoration: menu items and hubs are deliberate public gates and junctions in the Castle plumbing.
