The 20-route learning estate
eduKateSengkang is organised as a Learning Castle: existing subject hubs, level routes, examination routes and learning-system pages retain their jobs. This page is the master upgrade directory. It does not replace those owners. It makes the work visible, assigns every upgrade to one route, and gives new or substantially revised articles stable IDs so later batches can be connected without losing track of what is complete.
Numbering rule
Each route has a -000 hub pointer. Article slots then use reserved tens: -010, -020, -030 and so on. The first upgrade programme reserves up to 150 article slots per route, ending at -1500. Existing high-value URLs are upgraded in place wherever practical; the ID identifies the editorial job, not a requirement to create a new URL.

Article register
The first-wave titles and status ledger are live in the eduKate Sengkang Article Register | SK-01 to SK-20. Use it to claim the next article ID, see protected owners and avoid duplicating work already active in another branch.
Protection-first reader standard
All 20 branches now follow the eduKate Sengkang Reader Experience Standard: protect strong pages, connect isolated pages, improve formatting only where it helps, use bounded surgery for specific defects, and modernise only when the existing article no longer completes its reader job.
Article state
Every inspected URL receives one state before work begins: PROTECT for ranking or strategically sensitive owners; KEEP for sound pages needing no substantial rewrite; MODERNISE for useful but outdated pages; SURGERY for small bounded repairs; RETARGET for pages that need a distinct adjacent search job; CONSOLIDATION CANDIDATE for overlapping intent that requires owner review; LOCATION LEAKAGE for misplaced locality; or HISTORICAL for material worth preserving without major reinvestment.
Completion rule
An article ID becomes complete only when the assigned existing URL or new article has a defined reader job, correct owner, current factual scope, useful internal return path and no unresolved collision with another Sengkang owner. A branch can therefore inspect more than 150 URLs without rewriting 150 pages. The 150 slots are a controlled first-wave capacity, not a quota.
Castle relationship
This programme sits under the existing Learning Castle and follows its one-owner-many-routes rule. English, Mathematics, Science, Examination Craft, Learning Runtime and Algorithms retain their existing canonical roles. The master directory exists to coordinate upgrades and make unfinished work visible; it does not create twenty competing subject hubs.
Complete-index crosswalk
Use the 20 routes above to decide ownership and upgrade work. Use these Complete Archives when the job is enumeration, orphan control or direct deep-article discovery.
English Archive · Mathematics Archive · Science Archive · Examination Archive · Learning Runtime Archive · Algorithms & Computing Archive
Deep fallback discovery
The subject hubs and Complete Archives remain the preferred routes. These live indexes are the final orphan-control layer: they expose every published Page and Post through paginated internal links so newly published or unusually placed content still has a crawlable return path while specialist routing is updated.
